It is basically about the timing in the boot process. It is possible to merge them into one call if a runtime allows (binding specific).
gc_init(now calledmmtk_init): the runtime can call it at any time as long as it is before any other MMTk call. It does not assume anything about the runtime. Once this is done, the runtime can create mutators, and start allocating (but no GC will be triggered).initialize_collection: the runtime should only call this when it is ready for GC. This usually means the runtime should finish its thread system booting -- they should be able to create VM threads, block application threads, etc.

Is this file intended to be in the Julia repo in the long term? This is MMTk specific code, and this needs to be updated if there is any breaking changes in MMTk core. Putting this in the VM repo is usually not desired.
What we usually do is to allow the build system to search for an external directory for source code (specified at build time), and in that case, this file can be maintained in the binding repo, and for any MMTk changes, we will only need to update the binding.

Now that these changes are closer to complete, we should discuss which parts to move into the binding.

Throwing an error should be done by runtime, rather than GC. This should be the part of interface from GC -> runtime (GC calls runtime), rather than runtime -> GC.

For what I can find, this method and a few methods below are introduced in https://github.com/JuliaLang/Juleps/blob/master/GcExtensions.md. Julia program can call them to allow doing GC for foreign objects. We will have to provide an implementation for this. Ruby has some similar methods, and Kunshan introduced some mechanisms in MMTk to handle this. We should be fine.

We should make this low priority and focus on core functionality first. I'll keep a note of such logic.

If internal means pool allocation, and will be replaced with immix allocation, we need to get a constant from MMTk for the maximum object size.

I don't know if Eduardo implemented this or not. We can keep it, but we will need to go through sweep_objs at the end of GC, check with MMTk to see if those objects are live or not. Basically do this but replacing gc_marked with a check from MMTk.

This PR updates the binding to the latest Julia master (up to this commit: 134f3e7).
. Change build mechanism to better match other Julia optional libraries. . Reduce `#ifdef MMTK`s. . Add `gc-common.c` to hold GC code that is common to Julia's GC and MMTk. . Add `mmtk-gc.c` for MMTk-specific code. . Add `gc-interface.h` to document the GC interface.
The user can set `MMTK_BUILD` to `debug` or `release` explicitly. Otherwise, we choose based on whether the user starts a debug build or a regular build.
Foreign thread adoption can cause additional calls to `jl_init_thread_heap()` with a `ptls` that has `tid` 0. Thus we cannot use that condition to ensure that `initialize_collection` is called only once. Move the call back to `init.c`.

Merge only with mmtk/julia#5. - Correct prototype for `run_finalizer`. - Remove `jl_mmtk_gc_alloc_default_llvm`, no longer needed. - Remove calls to `gc_time_mallocd_array_*`, only needed with `GC_TIME`. - Remove call to `verify_parent1`, only needed with `GC_VERIFY`.

Even though it's not very common in julia's repo (why is that!?) it might be nice to leave a short file-level comment here explaining what this file is? It contains the parts of julia's GC implementation common to all GC backends ("native" GC and MMTk)

It would be a bigger, more disruptive change, but what if we put the rest of this .h file into its own file like "gc-native.h"?
(or whatever we want to call the non-MMTk GC)
Do you think that would be too disruptive? I guess that's a conversation that could be had on the MMTk=>JuliaLang PR
There was a problem hiding this comment.
I'd started with the same split as with gc.c, for each GC file, and felt it was too much. We can reassess when we open the PR upstream. Maybe we will move all of mmtk-gc.c and most code under #ifdef MMTK_GC to the binding (mmtk-julia).

Does MMTk's allocator not have a concept of realloc? My understanding is that sometimes this can save a lot of perf if you can avoid copying the array's bytes to a new region and just grow the buffer in place?

This is part of the work to address JuliaLang#51352 by attempting to allow the compiler to perform SRAO on persistent data structures like `PersistentDict` as if they were regular immutable data structures. These sorts of data structures have very complicated internals (with lots of mutation, memory sharing, etc.), but a relatively simple interface. As such, it is unlikely that our compiler will have sufficient power to optimize this interface by analyzing the implementation. We thus need to come up with some other mechanism that gives the compiler license to perform the requisite optimization. One way would be to just hardcode `PersistentDict` into the compiler, optimizing it like any of the other builtin datatypes. However, this is of course very unsatisfying. At the other end of the spectrum would be something like a generic rewrite rule system (e-graphs anyone?) that would let the PersistentDict implementation declare its interface to the compiler and the compiler would use this for optimization (in a perfect world, the actual rewrite would then be checked using some sort of formal methods). I think that would be interesting, but we're very far from even being able to design something like that (at least in Base - experiments with external AbstractInterpreters in this direction are encouraged). This PR tries to come up with a reasonable middle ground, where the compiler gets some knowledge of the protocol hardcoded without having to know about the implementation details of the data structure. The basic ideas is that `Core` provides some magic generic functions that implementations can extend. Semantically, they are not special. They dispatch as usual, and implementations are expected to work properly even in the absence of any compiler optimizations. However, the compiler is semantically permitted to perform structural optimization using these magic generic functions. In the concrete case, this PR introduces the `KeyValue` interface which consists of two generic functions, `get` and `set`. The core optimization is that the compiler is allowed to rewrite any occurrence of `get(set(x, k, v), k)` into `v` without additional legality checks. In particular, the compiler performs no type checks, conversions, etc. The higher level implementation code is expected to do all that. This approach closely matches the general direction we've been taking in external AbstractInterpreters for embedding additional semantics and optimization opportunities into Julia code (although we generally use methods there, rather than full generic functions), so I think we have some evidence that this sort of approach works reasonably well. Nevertheless, this is certainly an experiment and the interface is explicitly declared unstable. ## Current Status This is fully working and implemented, but the optimization currently bails on anything but the simplest cases. Filling all those cases in is not particularly hard, but should be done along with a more invasive refactoring of SROA, so we should figure out the general direction here first and then we can finish all that up in a follow-up cleanup. ## Obligatory benchmark Before: ``` julia> using BenchmarkTools julia> function foo() a = Base.PersistentDict(:a => 1) return a[:a] end foo (generic function with 1 method) julia> @benchmark foo() BenchmarkTools.Trial: 10000 samples with 993 evaluations.

* better signal handling (#55623)
Instead of relying on creating a fake stack frame, and having no signals
delivered, kernel bugs, accidentally gc_collect, or other issues occur
during the delivery and execution of these calls, use the ability we
added recently to emulate a longjmp into a unw_context to eliminate any
time where there would exist any invalid states.
Secondly, when calling jl_exit_thread0_cb, we used to end up completely
smashing the unwind info (with CFI_NOUNWIND), but this makes core files
from SIGQUIT much less helpful, so we now have a `fake_stack_pop`
function with contains the necessary CFI directives such that a minimal
unwind from the debugger will likely still succeed up into the frames
that were removed. We cannot do this perfectly on AArch64 since that
platform's DWARF spec lacks the ability to do so. On other platforms,
this should be possible to implement exactly (subject to libunwind
implementation quality). This is currently thus only fully implemented for
x86_64 on Darwin Apple.

Closes: https://github.com/JuliaLang/julia/pull/55674
* Make `rename` public (#55652)
Fixes #41584. Follow up of #55503
I think `rename` is a very useful low-level file system operation. Many
other programming languages have this function, so it is useful when
porting IO code to Julia.
One use case is to improve the Zarr.jl package to be more compatible
with zarr-python.
https://github.com/zarr-developers/zarr-python/blob/0b5483a7958e2ae5512a14eb424a84b2a75dd727/src/zarr/v2/storage.py#L994
uses the `os.replace` function. It would be nice to be able to directly
use `Base.rename` as a replacement for `os.replace` to ensure
compatibility.
Another use case is writing a safe zip file extractor in pure Julia.
https://github.com/madler/sunzip/blob/34107fa9e2a2e36e7e72725dc4c58c9ad6179898/sunzip.c#L365
uses the `rename` function to do this in C.
Lastly in
https://github.com/medyan-dev/MEDYANSimRunner.jl/blob/67d5b42cc599670486d5d640260a95e951091f7a/src/file-saving.jl#L83
I am using `ccall(:jl_fs_rename` to save files, because I have large
numbers of Julia processes creating and reading these files at the same
time on a distributed file system on a cluster, so I don't want data to
become corrupted if one of the nodes crashes (which happens fairly
regularly). However `jl_fs_rename` is not public, and might break in a
future release.
This PR also adds a note to `mv` comparing it to the `mv` command,
similar to the note on the `cp` function.

* Canonicalize names of nested functions by keeping a more fine grained counter -- per (module, method name) pair (#53719)
As mentioned in https://github.com/JuliaLang/julia/pull/53716, we've
been noticing that `precompile` statements lists from one version of our
codebase often don't apply cleanly in a slightly different version.
That's because a lot of nested and anonymous function names have a
global numeric suffix which is incremented every time a new name is
generated, and these numeric suffixes are not very stable across
codebase changes.
To solve this, this PR makes the numeric suffixes a bit more fine
grained: every pair of (module, top-level/outermost function name) will
have its own counter, which should make nested function names a bit more
stable across different versions.
This PR applies @JeffBezanson's idea of making the symbol name changes
directly in `current-julia-module-counter`.
Here is an example:
```Julia
julia> function foo(x)
function bar(y)
return x + y
end
end
foo (generic function with 1 method)
julia> f = foo(42)
(::var"#bar#foo##0"{Int64}) (generic function with 1 method)
```

* Fix various issues with PGO+LTO makefile (#55581)
This fixes various issues with the PGO+LTO makefile

https://github.com/JuliaLang/julia/blob/eb5587dac02d1f6edf486a71b95149139cc5d9f7/Make.inc#L734
This is because setting `CC` and `CCX` by passing them as arguments to
`make` prevents `Make.inc` from prepending these variables with `ccache`
as `Make.inc` doesn't use override. To workaround this I instead set
`USECLANG` and add the toolchain to the `PATH`.
- To deal with similar issues for the other make flags, I pass them as
environment variables which can be edited in `Make.inc`.
- I add a way to build in one go by creating the `all` target, now you
can just run `make` and a PGO+LTO build that profiles Julia's build will
be generated.
- I workaround `PROFRAW_FILES` not being reevaluated after `stage1`
builds, this caused the generation of `PROFILE_FILE` to run an outdated
command if `stage1` was built and affected the profraw files. This is
important when building in one go.
- I add a way to run rules like `binary-dist` which are not defined in
this makefile with the correct toolchain which for example prevents
`make binary-dist` from unnecessarily rebuilding `sys.ji`.
- Include `-Wl,--undefined-version` till

* Avoid materializing arrays in bidiag matmul (#55450)
Currently, small `Bidiagonal`/`Tridiagonal` matrices are materialized in
matrix multiplications, but this is wasteful and unnecessary. This PR
changes this to use a naive matrix multiplication for small matrices,
and fall back to the banded multiplication for larger ones.
Multiplication by a `Bidiagonal` falls back to a banded matrix
multiplication for all sizes in the current implementation, and iterates
in a cache-friendly manner for the non-`Bidiagonal` matrix.
In certain cases, the matrices were being materialized if the
non-structured matrix was small, even if the structured matrix was
large. This is changed as well in this PR.
Some improvements in performance:
```julia
julia> B = Bidiagonal(rand(3), rand(2), :U); A = rand(size(B)...); C = similar(A);
julia> @btime mul!($C, $A, $B);

* Various fixes to byte / bytearray search (#54579)
This was originally intended as a targeted fix to #54578, but I ran into
a bunch of smaller issues with this code that also needed to be solved
and it turned out to be difficult to fix them with small, trivial PRs.
I would also like to refactor this whole file, but I want these
correctness fixes to be merged first, because a larger refactoring has
higher risk of getting stuck without getting reviewed and merged.
## Larger things that needs decisions
* The internal union `Base.ByteArray` has been deleted. Instead, the
unions `DenseInt8` and `DenseUInt8` have been added. These more
comprehensively cover the types that was meant, e.g. `Memory{UInt8}` was
incorrectly not covered by the former. As stated in the TODO, the
concept of a "memory backed dense byte array" is needed throughout
Julia, so this ideally needs to be implemented as a single type and used
throughout Base. The fix here is a decent temporary solution. See #53178
#54581
* The `findall` docstring between two arrays was incorrectly not
attached to the method - now it is. **Note that this change _changes_
the documentation** since it includes a docstring that was previously
missed. Hence, it's an API addition.
* Added a new minimal `testhelpers/OffsetDenseArrays.jl` which provide a
`DenseVector` with offset axes for testing purposes.
## Trivial fixes
* `findfirst(==(Int8(-1)), [0xff])` and similar findlast, findnext and
findprev is no longer buggy, see #54578
* `findfirst([0x0ff], Int8[-1])` is similarly no longer buggy, see
#54578
* `findnext(==('\xa6'), "æ", 1)` and `findprev(==('\xa6'), "æa", 2)` no
longer incorrectly throws an error
* The byte-oriented find* functions now work correctly with offset
arrays
* Fixed incorrect use of `GC.@preserve`, where the pointer was taken
before the preserve block.
* More of the optimised string methods now also apply to
`SubString{String}`

* Update stable version number in readme to v1.10.5 (#55742)
* Add `invokelatest` barrier to `string(...)` in `@assert` (#55739)
This change protects `@assert` from invalidations to `Base.string(...)`
by adding an `invokelatest` barrier.
A common source of invalidations right now is `print(io,
join(args...))`. The problem is:
1. Inference concludes that `join(::Any...)` returns
`Union{String,AnnotatedString}`
2. The `print` call is union-split to `String` and `AnnotatedString`
3. This code is now invalidated when StyledStrings defines `print(io,
::AnnotatedString)`
The invalidation chain for `@assert` is similar: ` @assert 1 == 1` calls
into `string(::Expr)` which calls into `print(io, join(args::Any...))`.
Unfortunately that leads to the invalidation of almost all `@assert`s
without an explicit error message

fix #52986
* Assume that docstring code with no lang is julia (#55465)
* Broadcast binary ops involving strided triangular (#55798)
Currently, we evaluate expressions like `(A::UpperTriangular) +
(B::UpperTriangular)` using broadcasting if both `A` and `B` have
strided parents, and forward the summation to the parents otherwise.
This PR changes this to use broadcasting if either of the two has a
strided parent. This avoids accessing the parent corresponding to the
structural zero elements, as the index might not be initialized.
Fixes https://github.com/JuliaLang/julia/issues/55590
This isn't a general fix, as we still sum the parents if neither is
strided. However, it will address common cases.
This also improves performance, as we only need to loop over one half:
```julia
julia> using LinearAlgebra
julia> U = UpperTriangular(zeros(100,100));
julia> B = Bidiagonal(zeros(100), zeros(99), :U);
julia> @btime $U + $B;

* Reland " Avoid materializing arrays in bidiag matmul #55450" (#55777)
This relands #55450 and adds tests for the failing case noted in
https://github.com/JuliaLang/julia/issues/55727. The `addmul` tests that
were failing earlier pass with this change.
The issue in the earlier PR was that we were not exiting quickly for
`iszero(alpha)` in `_bibimul!` for small matrices, and were computing
the result as `C .= A * B * alpha + C * beta`. The problem with this is
that if `A * B` contains `NaN`s, this propagates to `C` even if `alpha
=== 0.0`. This is fixed now, and the result is only computed if
`!iszero(alpha)`.

Following a discussion on

* Markdown: support `parse(::AbstractString)` (#55747)
`Markdown.parse` is documented to accept `AbstractString` but it was
implemented by calling `IOBuffer` on the string argument. `IOBuffer`,
however, is documented only for `String` arguments.
This commit changes the current `parse(::AbstractString)` to
`parse(::String)` and implements `parse(::AbstractString)` by converting
the argument to `String`.
Now, even `LazyString`s can be parsed to Markdown representation.

* Specialize indexing triangular matrices with BandIndex (#55644)
With this, certain indexing operations involving a `BandIndex` may be

With this,
```julia
julia> n = 3; T = Tridiagonal(rand(n-1), rand(n), rand(n-1));
julia> @code_warntype ((T,j) -> UpperTriangular(T)[LinearAlgebra.BandIndex(2,j)])(T, 1)

│ %4 = Base.getindex(%1, %3)::Core.Const(0.0)

```
The indexing operation may be evaluated at compile-time, as the band
index is constant-propagated.

* Add filesystem func to transform a path to a URI (#55454)
In a few places across Base and the stdlib, we emit paths that we like
people to be able to click on in their terminal and editor. Up to this
point, we have relied on auto-filepath detection, but this does not
allow for alternative link text, such as contracted paths.
Doing so (via OSC 8 terminal links for example) requires filepath URI
encoding.
This functionality was previously part of a PR modifying stacktrace
printing (#51816), but after that became held up for unrelated reasons
and another PR appeared that would benefit from this utility (#55335),
I've split out this functionality so it can be used before the
stacktrace printing PR is resolved.
* constrain the path argument of `include` functions to `AbstractString` (#55466)
Each `Module` defined with `module` automatically gets an `include`
function with two methods. Each of those two methods takes a file path
as its last argument. Even though the path argument is unconstrained by
dispatch, it's documented as constrained with `::AbstractString`:
https://docs.julialang.org/en/v1.11-dev/base/base/#include
Furthermore, I think that any invocation of `include` with a
non-`AbstractString` path will necessarily throw a `MethodError`
eventually. Thus this change should be harmless.
Adding the type constraint to the path argument is an improvement
because any possible exception would be thrown earlier than before.
Apart from modules defined with `module`, the same issue is present with
the anonymous modules created by `evalfile`, which is also addressed.
Sidenote: `evalfile` seems to be completely untested apart from the test
added here.

* codegen: split gc roots from other bits on stack (#55767)
In order to help avoid memory provenance issues, and better utilize
stack space (somewhat), and use FCA less, change the preferred
representation of an immutable object to be a pair of
`<packed-data,roots>` values. This packing requires some care at the
boundaries and if the expected field alignment exceeds that of a
pointer. The change is expected to eventually make codegen more flexible
at representing unions of values with both bits and pointer regions.
Eventually we can also have someone improve the late-gc-lowering pass to
take advantage of this increased information accuracy, but currently it
will not be any better than before at laying out the frame.

* Root globals in toplevel exprs (#54433)

* inference: add missing `TypeVar` handling for `instanceof_tfunc` (#55884)
I thought these sort of problems had been addressed by d60f92c, but it
seems some were missed. Specifically, `t.a` and `t.b` from `t::Union`
could be `TypeVar`, and if they are passed to a subroutine or recursed
without being unwrapped or rewrapped, errors like JuliaLang/julia#55882
could occur.
This commit resolves the issue by calling `unwraptv` in the `Union`
handling within `instanceof_tfunc`. I also found a similar issue inside
`nfields_tfunc`, so that has also been fixed, and test cases have been
added. While I haven't been able to make up a test case specifically for
the fix in `instanceof_tfunc`, I have confirmed that this commit
certainly fixes the issue reported in JuliaLang/julia#55882.

This adds a command line option `--trim` that builds images where code
is only included if it is statically reachable from methods marked using
the new function `entrypoint`. Compile-time errors are given for call
sites that are too dynamic to allow trimming the call graph (however
there is an `unsafe` option if you want to try building anyway to see
what happens).
The PR has two other components. One is changes to Base that generally
allow more code to be compiled in this mode. These changes will either
be merged in separate PRs or moved to a separate part of the workflow
(where we will build a custom system image for this purpose). The branch
is set up this way to make it easy to check out and try the
functionality.
The other component is everything in the `juliac/` directory, which
implements a compiler driver script based on this new option, along with
some examples and tests. This will eventually become a package "app"
that depends on PackageCompiler and provides a CLI for all of this
stuff, so it will not be merged here. To try an example:
```
julia contrib/juliac.jl --output-exe hello --trim test/trimming/hello.jl
```
When stripped the resulting executable is currently about 900kb on my
machine.

* prevent loading other extensions when precompiling an extension (#55589)
The current way of loading extensions when precompiling an extension
very easily leads to cycles. For example, if you have more than one
extension and you happen to transitively depend on the triggers of one
of your extensions you will immediately hit a cycle where the extensions
will try to load each other indefinitely. This is an issue because you
cannot directly influence your transitive dependency graph so from this
p.o.v the current system of loading extension is "unsound".
The test added here checks this scenario and we can now precompile and
load it without any warnings or issues.

instead which could avoid those singled-threaded concurrency bugs.

This change ensures the compiler uses very little stack, making it
compatible with running on any arbitrary system stack size and depths
much more reliably. It also could be further modified now to easily add
various forms of pause-able/resumable inference, since there is no
implicit state on the stack--everything is local and explicit now.
Whereas before, less than 900 frames would crash in less than a second:
```

Warning: detected a stack overflow; program state may be corrupted, so further execution might be unreliable.

* optimizer: simplify the finalizer inlining pass a bit (#55934)
Minor adjustments have been made to the algorithm of the finalizer
inlining pass. Previously, it required that the finalizer registration
dominate all uses, but this is not always necessary as far as the
finalizer inlining point dominates all the uses. So the check has been
relaxed. Other minor fixes have been made as well, but their importance
is low.
* Limit `@inbounds` to indexing in the dual-iterator branch in `copyto_unaliased!` (#55919)
This simplifies the `copyto_unalised!` implementation where the source
and destination have different `IndexStyle`s, and limits the `@inbounds`
to only the indexing operation. In particular, the iteration over
`eachindex(dest)` is not marked as `@inbounds` anymore. This seems to
help with performance when the destination uses Cartesian indexing.
Reduced implementation of the branch:
```julia
function copyto_proposed!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
for (destind, srcind) in zip(iterdest, itersrc)
@inbounds dest[destind] = src[srcind]
end
dest
end
function copyto_current!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
ret = iterate(iterdest)
@inbounds for a in src
idx, state = ret::NTuple{2,Any}
dest[idx] = a
ret = iterate(iterdest, state)
end
dest
end
function copyto_current_limitinbounds!(dest, src)
axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes"))
iterdest, itersrc = eachindex(dest), eachindex(src)
ret = iterate(iterdest)
for isrc in itersrc
idx, state = ret::NTuple{2,Any}
@inbounds dest[idx] = src[isrc]
ret = iterate(iterdest, state)
end

I'm not quite certain why the proposed implementation here
(`copyto_proposed!`) is even faster than
`copyto_current_limitinbounds!`. In any case, `copyto_proposed!` is
easier to read, so I'm not complaining.

* Strong zero in Diagonal triple multiplication (#55927)
Currently, triple multiplication with a `LinearAlgebra.BandedMatrix`
sandwiched between two `Diagonal`s isn't associative, as this is
implemented using broadcasting, which doesn't assume a strong zero,
whereas the two-term matrix multiplication does.
```julia
julia> D = Diagonal(StepRangeLen(NaN, 0, 3));
julia> B = Bidiagonal(1:3, 1:2, :U);
julia> D * B * D
3×3 Matrix{Float64}:

julia> D * (B * D)

```
This PR ensures that the 3-term multiplication is evaluated as a
sequence of two-term multiplications, which fixes this issue. This also

* Fix dispatch on `alg` in Float16 Hermitian eigen (#55928)
Currently,
```julia
julia> using LinearAlgebra
julia> A = Hermitian(reshape(Float16[1:16;], 4, 4));
julia> eigen(A).values |> typeof
Vector{Float16} (alias for Array{Float16, 1})
julia> eigen(A, LinearAlgebra.QRIteration()).values |> typeof
Vector{Float32} (alias for Array{Float32, 1})
```
This PR moves the specialization on the `eltype` to an internal method,
so that firstly all `alg`s dispatch to that method, and secondly, there
are no ambiguities introduce by specializing the top-level `eigen`. The
latter currently causes test failures in `StaticArrays`
(https://github.com/JuliaArrays/StaticArrays.jl/actions/runs/11092206012/job/30816955210?pr=1279),
and should be fixed by this PR.
* Remove specialized `ishermitian` method for `Diagonal{<:Real}` (#55948)

checking that the `diag` is real, so we don't need this additional
specialization.
* Fix logic in `?` docstring example (#55945)
* fix `unwrap_macrocalls` (#55950)
The implementation of `unwrap_macrocalls` has assumed that what
`:macrocall` wraps is always an `Expr` object, but that is not
necessarily correct:
```julia

* make faster BigFloats (#55906)
We can coalesce the two required allocations for the MFPR BigFloat API
design into one allocation, hopefully giving a easy performance boost.
It would have been slightly easier and more efficient if MPFR BigFloat
was already a VLA instead of containing a pointer here, but that does
not prevent the optimization.

Revise wants to know what file a module's `module` definition is in.
Currently it does this by looking at the source location for the
implicitly generated `eval` method. This is terrible for two reasons:
1. The method may not exist if the module is a baremodule (which is not
particularly common, which is probably why we haven't seen it).
2. The fact that the implicitly generated `eval` method has this
location information is an implementation detail that I'd like to get
rid of (#55949).
This PR adds explicit file/line info to `Module`, so that Revise doesn't
have to use the hack anymore.

* [build] avoid libedit linkage and align libccalllazy* SONAMEs (#55968)
While building the 1.11.0-rc4 in Homebrew[^1] in preparation for 1.11.0
release (and to confirm Sequoia successfully builds) I noticed some odd
linkage for our Linux builds, which included of:
1. LLVM libraries were linking to `libedit.so`, e.g.
```
Dynamic Section:
NEEDED libedit.so.0
NEEDED libz.so.1
NEEDED libzstd.so.1
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libgcc_s.so.1
NEEDED libc.so.6
NEEDED ld-linux-x86-64.so.2
SONAME libLLVM-16jl.so
```
CMakeCache.txt showed
```
//Use libedit if available.
LLVM_ENABLE_LIBEDIT:BOOL=ON
```
Which might be overriding `HAVE_LIBEDIT` at
https://github.com/JuliaLang/llvm-project/blob/julia-release/16.x/llvm/cmake/config-ix.cmake#L222-L225.
So just added `LLVM_ENABLE_LIBEDIT`
2. Wasn't sure if there was a reason for this but `libccalllazy*` had
mismatched SONAME:
```console
❯ objdump -p lib/julia/libccalllazy* | rg '\.so'
lib/julia/libccalllazybar.so: file format elf64-x86-64
NEEDED ccalllazyfoo.so
SONAME ccalllazybar.so
lib/julia/libccalllazyfoo.so: file format elf64-x86-64
SONAME ccalllazyfoo.so
```
Modifying this, but can drop if intentional.

Hi everyone! First PR to Julia here.
It was noticed in a Slack thread yesterday
that `copy!(A, I)` doesn't work, but `copyto!(A, I)` does. This PR adds
the missing method for `copy!(::AbstractMatrix, ::UniformScaling)`,
which simply defers to `copyto!`, and corresponding tests.

However, this is still a WIP. Before merging, I want to improve EA's
precision a bit and at least fix the test case that is currently marked
as `broken`. I also need to check its impact on compiler performance.
Additionally, I believe this feature is not yet practical. In
particular, there is still significant room for improvement in the
following areas:
- EA's interprocedural capabilities: currently EA is performed ad-hoc
for limited frames because of latency reasons, which significantly
reduces its precision in the presence of interprocedural calls.
- Relaxing the `:nothrow` check for finalizer inlining: the current
algorithm requires `:nothrow`-ness on all paths from the allocation of
the mutable struct to its last use, which is not practical for
real-world cases. Even when `:nothrow` cannot be guaranteed, auxiliary
optimizations such as inserting a `finalize` call after the last use
might still be possible (JuliaLang#55990).

* Add filesystem func to transform a path to a URI (#55454) In a few places across Base and the stdlib, we emit paths that we like people to be able to click on in their terminal and editor. Up to this point, we have relied on auto-filepath detection, but this does not allow for alternative link text, such as contracted paths. Doing so (via OSC 8 terminal links for example) requires filepath URI encoding. This functionality was previously part of a PR modifying stacktrace printing (#51816), but after that became held up for unrelated reasons and another PR appeared that would benefit from this utility (#55335), I've split out this functionality so it can be used before the stacktrace printing PR is resolved. * constrain the path argument of `include` functions to `AbstractString` (#55466) Each `Module` defined with `module` automatically gets an `include` function with two methods. Each of those two methods takes a file path as its last argument. Even though the path argument is unconstrained by dispatch, it's documented as constrained with `::AbstractString`: https://docs.julialang.org/en/v1.11-dev/base/base/#include Furthermore, I think that any invocation of `include` with a non-`AbstractString` path will necessarily throw a `MethodError` eventually. Thus this change should be harmless. Adding the type constraint to the path argument is an improvement because any possible exception would be thrown earlier than before. Apart from modules defined with `module`, the same issue is present with the anonymous modules created by `evalfile`, which is also addressed. Sidenote: `evalfile` seems to be completely untested apart from the test added here.

This packing requires some care at the boundaries and if the expected field alignment exceeds that of a pointer. The change is expected to eventually make codegen more flexible at representing unions of values with both bits and pointer regions. Eventually we can also have someone improve the late-gc-lowering pass to take advantage of this increased information accuracy, but currently it will not be any better than before at laying out the frame. * Refactoring to be considered before adding MMTk * Removing jl_gc_notify_image_load, since it's a new function and not part of the refactoring * Moving gc_enable code to gc-common.c * Addressing PR comments * Push resolution of merge conflict * Removing jl_gc_mark_queue_obj_explicit extern definition from scheduler.c * Don't need the getter function since it's possible to use jl_small_typeof directly * WIP: Adding support for MMTk/Immix * Refactoring to be considered before adding MMTk * Adding fastpath allocation * Fixing removed newlines * Refactoring to be considered before adding MMTk * Adding a few comments; Moving some functions to be closer together * Fixing merge conflicts * Applying changes from refactoring before adding MMTk * Update TaskLocalRNG docstring according to #49110 (#55863) Since #49110, which is included in 1.10 and 1.11, spawning a task no longer advances the parent task's RNG state, so this statement in the docs was incorrect. * Root globals in toplevel exprs (#54433) This fixes #54422, the code here assumes that top level exprs are always rooted, but I don't see that referenced anywhere else, or guaranteed, so conservatively always root objects that show up in code. * codegen: fix alignment typos (#55880) So easy to type jl_datatype_align to get the natural alignment instead of julia_alignment to get the actual alignment.

Specifically, `t.a` and `t.b` from `t::Union` could be `TypeVar`, and if they are passed to a subroutine or recursed without being unwrapped or rewrapped, errors like JuliaLang/julia#55882 could occur. This commit resolves the issue by calling `unwraptv` in the `Union` handling within `instanceof_tfunc`. I also found a similar issue inside `nfields_tfunc`, so that has also been fixed, and test cases have been added.

Compile-time errors are given for call sites that are too dynamic to allow trimming the call graph (however there is an `unsafe` option if you want to try building anyway to see what happens). The PR has two other components. One is changes to Base that generally allow more code to be compiled in this mode. These changes will either be merged in separate PRs or moved to a separate part of the workflow (where we will build a custom system image for this purpose). The branch is set up this way to make it easy to check out and try the functionality. The other component is everything in the `juliac/` directory, which implements a compiler driver script based on this new option, along with some examples and tests. This will eventually become a package "app" that depends on PackageCompiler and provides a CLI for all of this stuff, so it will not be merged here.

To adapt, this changes `TOML.Parser` to be a type defined by the TOML stdlib, so that we can define methods on it without committing type-piracy and avoid problems like Pkg.jl#4017 Resolves https://github.com/JuliaLang/Pkg.jl/issues/4017#issuecomment-2377589989 * [FileWatching] fix PollingFileWatcher design and add workaround for a stat bug What started as an innocent fix for a stat bug on Apple (#48667) turned into a full blown investigation into the design problems with the libuv backend for PollingFileWatcher, and writing my own implementation of it instead which could avoid those singled-threaded concurrency bugs. * [FileWatching] fix FileMonitor similarly and improve pidfile reliability Previously pidfile used the same poll_interval as sleep to detect if this code made any concurrency mistakes, but we do not really need to do that once FileMonitor is fixed to be reliable in the presence of parallel concurrency (instead of using watch_file). * [FileWatching] reorganize file and add docs * Add `--trace-dispatch` (#55848) * relocation: account for trailing path separator in depot paths (#55355) Fixes #55340 * change compiler to be stackless (#55575) This change ensures the compiler uses very little stack, making it compatible with running on any arbitrary system stack size and depths much more reliably. It also could be further modified now to easily add various forms of pause-able/resumable inference, since there is no implicit state on the stack--everything is local and explicit now. Whereas before, less than 900 frames would crash in less than a second: ``` $ time ./julia -e 'f(::Val{N}) where {N} = N <= 0 ? 0 : f(Val(N - 1)); f(Val(1000))' Warning: detected a stack overflow; program state may be corrupted, so further execution might be unreliable. Internal error: during type inference of f(Base.Val{1000}) Encountered stack overflow. This might be caused by recursion over very long tuples or argument lists.

Previously, it required that the finalizer registration dominate all uses, but this is not always necessary as far as the finalizer inlining point dominates all the uses. So the check has been relaxed. Other minor fixes have been made as well, but their importance is low. * Limit `@inbounds` to indexing in the dual-iterator branch in `copyto_unaliased!` (#55919) This simplifies the `copyto_unalised!` implementation where the source and destination have different `IndexStyle`s, and limits the `@inbounds` to only the indexing operation. In particular, the iteration over `eachindex(dest)` is not marked as `@inbounds` anymore. This seems to help with performance when the destination uses Cartesian indexing. Reduced implementation of the branch: ```julia function copyto_proposed!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) for (destind, srcind) in zip(iterdest, itersrc) @inbounds dest[destind] = src[srcind] end dest end function copyto_current!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) ret = iterate(iterdest) @inbounds for a in src idx, state = ret::NTuple{2,Any} dest[idx] = a ret = iterate(iterdest, state) end dest end function copyto_current_limitinbounds!(dest, src) axes(dest) == axes(src) || throw(ArgumentError("incompatible sizes")) iterdest, itersrc = eachindex(dest), eachindex(src) ret = iterate(iterdest) for isrc in itersrc idx, state = ret::NTuple{2,Any} @inbounds dest[idx] = src[isrc] ret = iterate(iterdest, state) end dest end ``` ```julia julia> a = zeros(40000,4000); b = rand(size(a)...); julia> av = view(a, UnitRange.(axes(a))...); julia> @btime copyto_current!($av, $b); 617.704 ms (0 allocations: 0 bytes) julia> @btime copyto_current_limitinbounds!($av, $b); 304.146 ms (0 allocations: 0 bytes) julia> @btime copyto_proposed!($av, $b); 240.217 ms (0 allocations: 0 bytes) julia> versioninfo() Julia Version 1.12.0-DEV.1260 Commit 4a4ca9c8152 (2024-09-28 01:49 UTC) Build Info: Official https://julialang.org release Platform Info: OS: Linux (x86_64-linux-gnu) CPU: 8 × Intel(R) Core(TM) i5-10310U CPU @ 1.70GHz WORD_SIZE: 64 LLVM: libLLVM-18.1.7 (ORCJIT, skylake) Threads: 1 default, 0 interactive, 1 GC (on 8 virtual cores) Environment: JULIA_EDITOR = subl ``` I'm not quite certain why the proposed implementation here (`copyto_proposed!`) is even faster than `copyto_current_limitinbounds!`. In any case, `copyto_proposed!` is easier to read, so I'm not complaining. This fixes https://github.com/JuliaLang/julia/issues/53158 * Strong zero in Diagonal triple multiplication (#55927) Currently, triple multiplication with a `LinearAlgebra.BandedMatrix` sandwiched between two `Diagonal`s isn't associative, as this is implemented using broadcasting, which doesn't assume a strong zero, whereas the two-term matrix multiplication does. ```julia julia> D = Diagonal(StepRangeLen(NaN, 0, 3)); julia> B = Bidiagonal(1:3, 1:2, :U); julia> D * B * D 3×3 Matrix{Float64}: NaN NaN NaN NaN NaN NaN NaN NaN NaN julia> (D * B) * D 3×3 Bidiagonal{Float64, Vector{Float64}}: NaN NaN ⋅ ⋅ NaN NaN ⋅ ⋅ NaN julia> D * (B * D) 3×3 Bidiagonal{Float64, Vector{Float64}}: NaN NaN ⋅ ⋅ NaN NaN ⋅ ⋅ NaN ``` This PR ensures that the 3-term multiplication is evaluated as a sequence of two-term multiplications, which fixes this issue. This also improves performance, as only the bands need to be evaluated now. ```julia julia> D = Diagonal(1:1000); B = Bidiagonal(1:1000, 1:999, :U); julia> @btime $D * $B * $D; 656.364 μs (11 allocations: 7.63 MiB) # v"1.12.0-DEV.1262" 2.483 μs (12 allocations: 31.50 KiB) # This PR ``` * Fix dispatch on `alg` in Float16 Hermitian eigen (#55928) Currently, ```julia julia> using LinearAlgebra julia> A = Hermitian(reshape(Float16[1:16;], 4, 4)); julia> eigen(A).values |> typeof Vector{Float16} (alias for Array{Float16, 1}) julia> eigen(A, LinearAlgebra.QRIteration()).values |> typeof Vector{Float32} (alias for Array{Float32, 1}) ``` This PR moves the specialization on the `eltype` to an internal method, so that firstly all `alg`s dispatch to that method, and secondly, there are no ambiguities introduce by specializing the top-level `eigen`. The latter currently causes test failures in `StaticArrays` (https://github.com/JuliaArrays/StaticArrays.jl/actions/runs/11092206012/job/30816955210?pr=1279), and should be fixed by this PR. * Remove specialized `ishermitian` method for `Diagonal{<:Real}` (#55948) The fallback method for `Diagonal{<:Number}` handles this already by checking that the `diag` is real, so we don't need this additional specialization. * Fix logic in `?` docstring example (#55945) * fix `unwrap_macrocalls` (#55950) The implementation of `unwrap_macrocalls` has assumed that what `:macrocall` wraps is always an `Expr` object, but that is not necessarily correct: ```julia julia> Base.@assume_effects :nothrow @show 42 ERROR: LoadError: TypeError: in typeassert, expected Expr, got a value of type Int64 Stacktrace: [1] unwrap_macrocalls(ex::Expr) @ Base ./expr.jl:906 [2] var"@assume_effects"(__source__::LineNumberNode, __module__::Module, args::Vararg{Any}) @ Base ./expr.jl:756 in expression starting at REPL[1]:1 ``` This commit addresses this issue. * make faster BigFloats (#55906) We can coalesce the two required allocations for the MFPR BigFloat API design into one allocation, hopefully giving a easy performance boost. It would have been slightly easier and more efficient if MPFR BigFloat was already a VLA instead of containing a pointer here, but that does not prevent the optimization. * Add propagate_inbounds_meta to atomic genericmemory ops (#55902) `memoryref(mem, i)` will otherwise emit a boundscheck. ``` ; │ @ /home/vchuravy/WorkstealingQueues/src/CLL.jl:53 within `setindex_atomic!` @ genericmemory.jl:329 ; │┌ @ boot.jl:545 within `memoryref` %ptls_field = getelementptr inbounds i8, ptr %tls_pgcstack, i64 16 %ptls_load = load ptr, ptr %ptls_field, align 8 %"box::GenericMemoryRef" = call noalias nonnull align 8 dereferenceable(32) ptr @ijl_gc_small_alloc(ptr %ptls_load, i32 552, i32 32, i64 23456076646928) #9 %"box::GenericMemoryRef.tag_addr" = getelementptr inbounds i64, ptr %"box::GenericMemoryRef", i64 -1 store atomic i64 23456076646928, ptr %"box::GenericMemoryRef.tag_addr" unordered, align 8 store ptr %memoryref_data, ptr %"box::GenericMemoryRef", align 8 %.repack8 = getelementptr inbounds { ptr, ptr }, ptr %"box::GenericMemoryRef", i64 0, i32 1 store ptr %memoryref_mem, ptr %.repack8, align 8 call void @ijl_bounds_error_int(ptr nonnull %"box::GenericMemoryRef", i64 %7) unreachable ``` For the Julia code: ```julia function Base.setindex_atomic!(buf::WSBuffer{T}, order::Symbol, val::T, idx::Int64) where T @inbounds Base.setindex_atomic!(buf.buffer, order, val,((idx - 1) & buf.mask) + 1) end ``` from https://github.com/gbaraldi/WorkstealingQueues.jl/blob/0ebc57237cf0c90feedf99e4338577d04b67805b/src/CLL.jl#L41 * fix rounding mode in construction of `BigFloat` from pi (#55911) The default argument of the method was outdated, reading the global default rounding directly, bypassing the `ScopedValue` stuff. * fix `nonsetable_type_hint_handler` (#55962) The current implementation is wrong, causing it to display inappropriate hints like the following: ```julia julia> s = Some("foo"); julia> s[] = "bar" ERROR: MethodError: no method matching setindex!(::Some{String}, ::String) The function `setindex!` exists, but no method is defined for this combination of argument types.

This fixes it up. * Explicitly store a module's location (#55963) Revise wants to know what file a module's `module` definition is in. Currently it does this by looking at the source location for the implicitly generated `eval` method. This is terrible for two reasons: 1. The method may not exist if the module is a baremodule (which is not particularly common, which is probably why we haven't seen it). 2. The fact that the implicitly generated `eval` method has this location information is an implementation detail that I'd like to get rid of (#55949). This PR adds explicit file/line info to `Module`, so that Revise doesn't have to use the hack anymore. * mergewith: add single argument example to docstring (#55964) I ran into this edge case.

LLVM libraries were linking to `libedit.so`, e.g. ``` Dynamic Section: NEEDED libedit.so.0 NEEDED libz.so.1 NEEDED libzstd.so.1 NEEDED libstdc++.so.6 NEEDED libm.so.6 NEEDED libgcc_s.so.1 NEEDED libc.so.6 NEEDED ld-linux-x86-64.so.2 SONAME libLLVM-16jl.so ``` CMakeCache.txt showed ``` //Use libedit if available.

So just added `LLVM_ENABLE_LIBEDIT` 2. Wasn't sure if there was a reason for this but `libccalllazy*` had mismatched SONAME: ```console ❯ objdump -p lib/julia/libccalllazy* | rg '\.so' lib/julia/libccalllazybar.so: file format elf64-x86-64 NEEDED ccalllazyfoo.so SONAME ccalllazybar.so lib/julia/libccalllazyfoo.so: file format elf64-x86-64 SONAME ccalllazyfoo.so ``` Modifying this, but can drop if intentional. --- [^1]: https://github.com/Homebrew/homebrew-core/pull/192116 * Add missing `copy!(::AbstractMatrix, ::UniformScaling)` method (#55970) Hi everyone! First PR to Julia here. It was noticed in a Slack thread yesterday that `copy!(A, I)` doesn't work, but `copyto!(A, I)` does. This PR adds the missing method for `copy!(::AbstractMatrix, ::UniformScaling)`, which simply defers to `copyto!`, and corresponding tests.

Fix that by running the test in a fresh subprocess. * fix comma logic in time_print (#55977) Minor formatting fix * optimizer: fix up the inlining algorithm to use correct `nargs`/`isva` (#55976) It appears that inlining.jl was not updated in JuliaLang/julia#54341. Specifically, using `nargs`/`isva` from `mi.def::Method` in `ir_prepare_inlining!` causes the following error to occur: ```julia function generate_lambda_ex(world::UInt, source::LineNumberNode, argnames, spnames, @nospecialize body) stub = Core.GeneratedFunctionStub(identity, Core.svec(argnames...), Core.svec(spnames...)) return stub(world, source, body) end function overdubbee54341(a, b) return a + b end const overdubee_codeinfo54341 = code_lowered(overdubbee54341, Tuple{Any, Any})[1] function overdub_generator54341(world::UInt, source::LineNumberNode, selftype, fargtypes) if length(fargtypes) != 2 return generate_lambda_ex(world, source, (:overdub54341, :args), (), :(error("Wrong number of arguments"))) else return copy(overdubee_codeinfo54341) end end @eval function overdub54341(args...) $(Expr(:meta, :generated, overdub_generator54341)) $(Expr(:meta, :generated_only)) end topfunc(x) = overdub54341(x, 2) ``` ```julia julia> topfunc(1) Internal error: during type inference of topfunc(Int64) Encountered unexpected error in runtime: BoundsError(a=Array{Any, 1}(dims=(2,), mem=Memory{Any}(8, 0x10632e780)[SSAValue(2), SSAValue(3), #<null>, #<null>, #<null>, #<null>, #<null>, #<null>]), i=(3,)) throw_boundserror at ./essentials.jl:14 getindex at ./essentials.jl:909 [inlined] ssa_substitute_op! at ./compiler/ssair/inlining.jl:1798 ssa_substitute_op! at ./compiler/ssair/inlining.jl:1852 ir_inline_item! at ./compiler/ssair/inlining.jl:386 ... ``` This commit updates the abstract interpretation and inlining algorithm to use the `nargs`/`isva` values held by `CodeInfo`.

So fix and add tests. * adjust EA to JuliaLang/julia#52527 (#55986) `EnterNode.catch_dest` can now be `0` after the `try`/`catch` elision feature implemented in JuliaLang/julia#52527, and we actually need to adjust `EscapeAnalysis.compute_frameinfo` too. * Improvements to JITLink Seeing what this will look like, since it has a number of features (delayed compilation, concurrent compilation) that are starting to become important, so it would be nice to switch to only supporting one common implementation of memory management. Refs #50248 I am expecting https://github.com/llvm/llvm-project/issues/63236 may cause some problems, since we reconfigured some CI machines to minimize that issue, but it is still likely relevant. * rewrite catchjmp asm to use normal relocations instead of manual editing * add logic to prefer loading modules that are already loaded (#55908) Iterate over the list of existing loaded modules for PkgId whenever loading a new module for PkgId, so that we will use that existing build_id content if it otherwise passes the other stale_checks. * Apple: fix bus error on smaller readonly file in unix (#55859) Enables the fix for #28245 in #44354 for Apple now that the Julia bugs are fixed by #55641 and #55877.

This is technically fallible, but can't actually fail when A is a Memory or Array. Remove the dead error branch by casting to UInt instead. Similarly, in repeat(x, r), r is first checked to be nonnegative, then converted to UInt, then used in multiple calls where it is converted to UInt each time.

Fix #55998. * cleanup functions of Hermitian matrices (#55951) The functions of Hermitian matrices are a bit of a mess. For example, if we have a Hermitian matrix `a` with negative eigenvalues, `a^0.5` doesn't produce the `Symmetric` wrapper, but `sqrt(a)` does. On the other hand, if we have a positive definite `b`, `b^0.5` will be `Hermitian`, but `sqrt(b)` will be `Symmetric`: ```julia using LinearAlgebra a = Hermitian([1.0 2.0;2.0 1.0]) a^0.5 sqrt(a) b = Hermitian([2.0 1.0; 1.0 2.0]) b^0.5 sqrt(b) ``` This sort of arbitrary assignment of wrappers happens with pretty much all functions defined there. There's also some oddities, such as `cis` being the only function defined for `SymTridiagonal`, even though all `eigen`-based functions work, and `cbrt` being the only function not defined for complex Hermitian matrices. I did a cleanup: I defined all functions for `SymTridiagonal` and `Hermitian{<:Complex}`, and always assigned the appropriate wrapper, preserving the input one when possible. There's an inconsistency remaining that I didn't fix, that only `sqrt` and `log` accept a tolerance argument, as changing that is probably breaking. There were also hardly any tests that I could find (only `exp`, `log`, `cis`, and `sqrt`). I'm happy to add them if it's desired. * Fix no-arg `ScopedValues.@with` within a scope (#56019) Fixes https://github.com/JuliaLang/julia/issues/56017 * LinearAlgebra: make matprod_dest public (#55537) Currently, in a matrix multiplication `A * B`, we use `B` to construct the destination. However, this may not produce the optimal destination type, and is essentially single-dispatch. Letting packages specialize `matprod_dest` would help us obtain the optimal type by dispatching on both the arguments. This may significantly improve performance in the matrix multiplication. As an example: ```julia julia> using LinearAlgebra, FillArrays, SparseArrays julia> F = Fill(3, 10, 10); julia> s = sprand(10, 10, 0.1); julia> @btime $F * $s; 15.225 μs (10 allocations: 4.14 KiB) julia> typeof(F * s) SparseMatrixCSC{Float64, Int64} julia> nnz(F * s) 80 julia> VERSION v"1.12.0-DEV.1074" ``` In this case, the destination is a sparse matrix with 80% of its elements filled and being set one-by-one, which is terrible for performance. Instead, if we specialize `matprod_dest` to return a dense destination, we may obtain ```julia julia> LinearAlgebra.matprod_dest(F::FillArrays.AbstractFill, S::SparseMatrixCSC, ::Type{T}) where {T} = Matrix{T}(undef, size(F,1), size(S,2)) julia> @btime $F * $s; 754.632 ns (2 allocations: 944 bytes) julia> typeof(F * s) Matrix{Float64} ``` Potentially, this may be improved further by specializing `mul!`, but this is a 20x improvement just by choosing the right destination. Since this is being made public, we may want to bikeshed on an appropriate name for the function. * Sockets: Warn when local network access not granted.

This is because `SymTridiagonal` symmetrizes the values along the diagonal, so setting a diagonal entry to an asymmetric value would lead to a subsequent `getindex` producing a different result. ```julia julia> s = SMatrix{2,2}(1:4); julia> S = SymTridiagonal(fill(s,4), fill(s,3)) 4×4 SymTridiagonal{SMatrix{2, 2, Int64, 4}, Vector{SMatrix{2, 2, Int64, 4}}}: [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] [1 3; 2 4] ⋅ ⋅ [1 2; 3 4] [1 3; 3 4] julia> S[1,1] = s 2×2 SMatrix{2, 2, Int64, 4} with indices SOneTo(2)×SOneTo(2): 1 3 2 4 julia> S[1,1] == s false julia> S[1,1] 2×2 Symmetric{Int64, SMatrix{2, 2, Int64, 4}} with indices SOneTo(2)×SOneTo(2): 1 3 3 4 ``` After this PR, ```julia julia> S[1,1] = s ERROR: ArgumentError: cannot set a diagonal entry of a SymTridiagonal to an asymmetric value ``` * Remove unused matrix type params in diag methods (#56048) These parameters are not used in the method, and are unnecessary for dispatch. * LinearAlgebra: diagzero for non-OneTo axes (#55252) Currently, the off-diagonal zeros for a block-`Diagonal` matrix is computed using `diagzero`, which calls `zeros` for the sizes of the elements. This returns an `Array`, unless one specializes `diagzero` for the custom `Diagonal` matrix type. This PR defines a `zeroslike` function that dispatches on the axes of the elements, which lets packages specialize on the axes to return custom `AbstractArray`s. Choosing to specialize on the `eltype` avoids the need to specialize on the container, and allows packages to return appropriate types for custom axis types. With this, ```julia julia> LinearAlgebra.zeroslike(::Type{S}, ax::Tuple{SOneTo, Vararg{SOneTo}}) where {S<:SMatrix} = SMatrix{map(length, ax)...}(ntuple(_->zero(eltype(S)), prod(length, ax))) julia> D = Diagonal(fill(SMatrix{2,3}(1:6), 2)) 2×2 Diagonal{SMatrix{2, 3, Int64, 6}, Vector{SMatrix{2, 3, Int64, 6}}}: [1 3 5; 2 4 6] ⋅ ⋅ [1 3 5; 2 4 6] julia> D[1,2] # now an SMatrix 2×3 SMatrix{2, 3, Int64, 6} with indices SOneTo(2)×SOneTo(3): 0 0 0 0 0 0 julia> LinearAlgebra.zeroslike(::Type{S}, ax::Tuple{SOneTo, Vararg{SOneTo}}) where {S<:MMatrix} = MMatrix{map(length, ax)...}(ntuple(_->zero(eltype(S)), prod(length, ax))) julia> D = Diagonal(fill(MMatrix{2,3}(1:6), 2)) 2×2 Diagonal{MMatrix{2, 3, Int64, 6}, Vector{MMatrix{2, 3, Int64, 6}}}: [1 3 5; 2 4 6] ⋅ ⋅ [1 3 5; 2 4 6] julia> D[1,2] # now an MMatrix 2×3 MMatrix{2, 3, Int64, 6} with indices SOneTo(2)×SOneTo(3): 0 0 0 0 0 0 ``` The reason this can't be the default behavior is that we are not guaranteed that there exists a `similar` method that accepts the combination of axes. This is why we have to fall back to using the sizes, unless a specialized method is provided by a package. One positive outcome of this is that indexing into such a block-diagonal matrix will now usually be type-stable, which mitigates https://github.com/JuliaLang/julia/issues/45535 to some extent (although it doesn't resolve the issue). I've also updated the `getindex` for `Bidiagonal` to use `diagzero`, instead of the similarly defined `bidiagzero` function that it was using. Structured block matrices may now use `diagzero` uniformly to generate the zero elements. * Multi-argument `gcdx(a, b, c...)` (#55935) Previously, `gcdx` only worked for two arguments - but the underlying idea extends to any (nonzero) number of arguments. Similarly, `gcd` already works for 1, 2, 3+ arguments. This PR implements the 1 and 3+ argument versions of `gcdx`, following the [wiki page](https://en.wikipedia.org/wiki/Extended_Euclidean_algorithm#The_case_of_more_than_two_numbers) for the Extended Euclidean algorithm. * Refactoring to be considered before adding MMTk * Removing jl_gc_notify_image_load, since it's a new function and not part of the refactoring * Moving gc_enable code to gc-common.c * Addressing PR comments * Push resolution of merge conflict * Removing jl_gc_mark_queue_obj_explicit extern definition from scheduler.c * Don't need the getter function since it's possible to use jl_small_typeof directly * Remove extern from free_stack declaration in julia_internal.h * Putting everything that is common GC tls into gc-tls-common.h * Typo * Adding gc-tls-common.h to Makefile as a public header * Adding jl_full_sweep_reasons since timing.jl depends on it * Fixing issue with jl_full_sweep_reasons (missing constants) * fix `_growbeg!` unncessary resizing (#56029) This was very explicitly designed such that if there was a bunch of extra space at the end of the array, we would copy rather than allocating, but by making `newmemlen` be at least `overallocation(memlen)` rather than `overallocation(len)`, this branch was never hit. found by https://github.com/JuliaLang/julia/issues/56026 * REPL: hide any prints to stdio during `complete_line` (#55959) * teach llvm-alloc-helpers about `gc_loaded` (#56030) combined with https://github.com/JuliaLang/julia/pull/55913, the compiler is smart enough to fully remove ``` function f() m = Memory{Int}(undef, 3) @inbounds m[1] = 2 @inbounds m[2] = 2 @inbounds m[3] = 4 @inbounds return m[1] + m[2] + m[3] end ``` * mpfr: prevent changing precision (#56049) Changing precision requires reallocating the data field, which is better done by making a new BigFloat (since they are conceptually immutable anyways). Also do a bit a cleanup while here. Closes #56044 * stackwalk: fix jl_thread_suspend_and_get_state race (#56047) There was a missing re-assignment of old = -1; at the end of that loop which means in the ABA case, we accidentally actually acquire the lock on the thread despite not actually having stopped the thread; or in the counter-case, we try to run through this logic with old==-1 on the next iteration, and that isn't valid either (jl_thread_suspend_and_get_state should return failure and the loop will abort too early).

Seems cleaner to use the iteration interface for this. Also avoids some invalidations (https://github.com/JuliaLang/julia/issues/56080#issuecomment-2404765120) Co-authored-by: KristofferC <[email protected]> * array: inline `convert` where possible (#56034) This improves a common scenario, where someone wants to `push!` a poorly-typed object onto a well-typed Vector. For example: ```julia const NT = @NamedTuple{x::Int,y::Any} foo(v::Vector{NT}, x::Int, @nospecialize(y)) = push!(v, (; x, y)) ``` The `(; x, y)` is slightly poorly-typed here. It could have any type for its `.y` field before it is converted inside the `push!` to a NamedTuple with `y::Any` Without this PR, the dispatch for this `push!` cannot be inferred: ```julia julia> code_typed(foo, (Vector{NT}, Int, Any))[1] CodeInfo( 1 ─ ... │ %4 = %new(%3, x, y)::NamedTuple{(:x, :y), <:Tuple{Int64, Any}} │ %5 = Main.push!(v, %4)::Vector{@NamedTuple{x::Int64, y}} └── return %5 ) => Vector{@NamedTuple{x::Int64, y}} ``` With this PR, the above dynamic call is fully statically resolved and inlined (and therefore `--trim` compatible) * Remove some unnecessary `real` specializations for structured matrices (#56083) The `real(::AbstractArray{<:Rea})` fallback method should handle these cases correctly. * Combine `diag` methods for `SymTridiagonal` (#56014) Currently, there are two branches, one for an `eltype` that is a `Number`, and the other that deals with generic `eltype`s. They do similar things, so we may combine these, and use branches wherever necessary to retain the performance. We also may replace explicit materialized arrays by generators in `copyto!`. Overall, this improves performance in `diag` for matrices of matrices, whereas the performance in the common case of matrices of numbers remains unchanged. ```julia julia> using StaticArrays, LinearAlgebra julia> s = SMatrix{2,2}(1:4); julia> S = SymTridiagonal(fill(s,100), fill(s,99)); julia> @btime diag($S); 1.292 μs (5 allocations: 7.16 KiB) # nightly, v"1.12.0-DEV.1317" 685.012 ns (3 allocations: 3.19 KiB) # This PR ``` This PR also allows computing the `diag` for more values of the band index `n`: ```julia julia> diag(S,99) 1-element Vector{SMatrix{2, 2, Int64, 4}}: [0 0; 0 0] ``` This would work as long as `getindex` works for the `SymTridiagonal` for that band, and the zero element may be converted to the `eltype`. * fix `Vararg{T,T} where T` crashing `code_typed` (#56081) Not sure this is the right place to fix this error, perhaps `match.spec_types` should always be a tuple of valid types? fixes #55916 --------- Co-authored-by: Jameson Nash <[email protected]> * [libblastrampoline_jll] Upgrade to v5.11.1 (#56094) v5.11.1 is a patch release with a couple of RISC-V fixes. * Revert "REPL: hide any prints to stdio during `complete_line`" (#56102) * Remove warning from c when binding is ambiguous (#56103) * make `Base.ANSIIterator` have a concrete field (#56088) Avoids the invalidation ``` backedges: 1: superseding sizeof(s::AbstractString) @ Base strings/basic.jl:177 with MethodInstance for sizeof(::AbstractString) (75 children) ``` shown in https://github.com/JuliaLang/julia/issues/56080#issuecomment-2404765120.

(#56007) The main motivation of this PR is to fix #55807. dc689fe8700f70f4a4e2dbaaf270f26b87e79e04 tries to remove the slow `may_contain_union_decision` check by re-organizing the code path. Now the fast path has been removed and most of its optimization has been integrated into the preserved slow path. Since the slow path stores all inner ∃ decisions on the outer most R stack, there might be overflow risk. aee69a41441b4306ba3ee5e845bc96cb45d9b327 should fix that concern.

Because that removes some functionality (the pass itself). So LLVM.jl and friends might need annoying version code. We can maybe keep the code there and just not run the pass in a backport. * Fix implicit `convert(String, ...)` in several places (#56174) This removes several `convert(String, ...)` from this code, which really shouldn't be something we invalidate on in the first place (see https://github.com/JuliaLang/julia/issues/56173) but this is still an improvement in code quality so let's take it. * Change annotations to use a NamedTuple (#55741) Due to popular demand, the type of annotations is to be changed from a `Tuple{UnitRange{Int}, Pair{Symbol, Any}}` to a `NamedTuple{(:region, :label, :value), Tuple{UnitRange{Int}, Symbol, Any}}`. This requires the expected code churn to `strings/annotated.jl`, and some changes to the StyledStrings and JuliaSyntaxHighlighting libraries. Closes #55249 and closes #55245. * Getting rid of mmtk_julia.c in the binding and moving it to gc-mmtk.c * Trying to organize and label the code in gc-mmtk.c * Remove redundant `convert` in `_setindex!` (#56178) Follow up to #56034, ref: https://github.com/JuliaLang/julia/pull/56034#discussion_r1798573573. --------- Co-authored-by: Cody Tapscott <[email protected]> * Improve type inference of Artifacts.jl (#56118) This also has some changes that move platform selection to compile time together with https://github.com/JuliaPackaging/JLLWrappers.jl/commit/45cc04963f3c99d4eb902f97528fe16fc37002cc, move the platform selection to compile time.

If a MethodError arises on a anonyomous function, the words "anonymous function" are printed in the error like so: ```julia g=(x,y)->x+y g(1,2,3) ``` ``` ERROR: MethodError: no method of the anonymous function var"mmtk#5#6" matching (::var"mmtk#5#6")(::Int64, ::Int64, ::Int64) The function `mmtk#5` exists, but no method is defined for this combination of argument types. Closest candidates are: (::var"mmtk#5#6")(::Any, ::Any) @ Main REPL[4]:1 ``` See the [original pull request](JuliaLang#57319) and [issue](JuliaLang#56325) JuliaLang#56325

Simplify `workqueue_for`. While not strictly necessary, the acquire load
in `getindex(once::OncePerThread{T,F}, tid::Integer)` makes
ThreadSanitizer happy. With the existing implementation, we get false
positives whenever a thread other than the one that originally allocated
the array reads it:

This moves the `getindex(::Memory, ::Int)` bounds check to Julia, which is how it's already done for `getindex(::Array, ::Int)`, so I guess it's correct. Also deduplicate the bounds checking code while at it. * Define textwidth for overlong chars (#58602) Previously, this would error. There is no guarantee of how terminals render overlong encodings.

This helps users discover that they may need to import a function or ensure multiple functions are the same generic function. - For Base functions: suggests importing (e.g., "You may have intended to import Base.length") - For other modules: suggests they may be intended as the same generic function - Shows all matches from relevant modules in sorted order - Uses modulesof! to properly handle all type structures including unions Fixes #58682 * Fix markdown bullet list in variables-and-scoping.md (#58771) * CONTRIBUTING.md: Ask folks to disclose AI-written PRs (#58666) * Convert julia-repl blocks to jldoctest format (#58594) Convert appropriate julia-repl code blocks to jldoctest format to enable automatic testing. In addition, this introduces a new `nodoctest = "reason"` pattern to annotate code blocks that are deliberate not doctested, so future readers will know not to try. Many code blocks are converted, in particular: - Manual pages: arrays.md, asynchronous-programming.md, functions.md, integers-and-floating-point-numbers.md, metaprogramming.md, multi-threading.md, performance-tips.md, variables.md, variables-and-scoping.md - Base documentation: abstractarray.jl, bitarray.jl, expr.jl, file.jl, float.jl, iddict.jl, path.jl, scopedvalues.md, sort.md - Standard library: Dates/conversions.jl, Random/RNGs.jl, Sockets/addrinfo.jl Key changes: - Add filters for non-deterministic output (timing, paths, memory addresses) - Add setup/teardown for filesystem operations - Fix parentmodule(M) usage in expr.jl for doctest compatibility - Document double escaping requirement for regex filters in docstrings - Update AGENTS.md with test running instructions Note: Some julia-repl blocks were intentionally left unchanged when they demonstrate language internals subject to change or contain non-deterministic output that cannot be properly filtered.

Tangentially related to #10092 ? This PR introduces the `nth(itr, n)` function to iterators to give a `getindex` type of behaviour. I've tried my best to optimize as much as possible by specializing on different types of iterators. In the spirit of iterators any OOB access returns `nothing`. (edit: instead of throwing an error, i.e. `first(itr, n)` and `last(itr, n)`) here is the comparison of running the testsuite (~22 different iterators) using generic `nth` and specialized `nth`: ```julia @btime begin for (itr, n, _) in $testset _fallback_nth(itr, n) end end 117.750 μs (366 allocations: 17.88 KiB) @btime begin for (itr, n, _) in $testset nth(itr, n) end end 24.250 μs (341 allocations: 16.70 KiB) ``` --------- Co-authored-by: adienes <[email protected]> Co-authored-by: Steven G.

As far as I know this only really impacts `AbstractArray` so, I've implemented a proposal that does some unrolling / pipelining manually to recover `AbstractArray` hashing performance. in fact, it's quite a lot faster now for most lengths.

Fix #58801 Note that this is thought not to be a problem for CleanupWriteBarriers, since while that does read the previously-inaccessibleMemOnly state, these functions are not marked nosync, so as long as the global state can be read, it also must be assumed that it might observe another thread has written to any global state. * Revert code changes from "strengthen assume_effects doc" PR (#58289) Reverts only the functional changes from JuliaLang/julia#58254, not the docs. Accessing this field here assumes that the counter valid is numeric and relevant to the current inference frame, neither of which is intended to be true, as we continue to add interfaces to execute methods outside of their current specific implementation with a monotonic world counter (e.g. with invoke on a Method, with precompile files, with external MethodTables, or with static compilation). * build: Error when attempting to set USECLANG/USEGCC (#58795) Way back in the good old days, these used to switch between GCC and Clang. I guess these days we always auto-switch based on the CC value. If you try to directly set USECLANG, things get into a bad state. Give a better error message for that case. * build: Add --no-same-owner to TAR (#58796) tar changes behavior when the current uid is 0 to try to also restore owner uids/gids (if recorded). It is possible for the uid to be 0 in single-uid environments like user namespace sandboxes, in which case the attempt to change the uid/gid fails. Of course ideally, the tars would have been created non-archival (so that the uid/gid wasn't recorded in the first place), but we get source tars from various places, so we can't guarantee this. To make sure we don't run into trouble, manually add the --no-same-owner flag to disable this behavior. * Add `cfunction` support for `--trim` (#58812) * fix error message for `eachindex(::Vararg{Tuple})` (#58811) Make the error message in case of mismatch less confusing and consistent with the error message for arrays.

I think this is only a partial fix, since we can still end up loading code from pkgimages that has been poorly inferred due to running without these `InferenceParams`. However, many of the common scenarios (such as JLL's depending on each other) seem to be OK since we have a targeted heuristic that adds `__init__()` to a pkgimage only if the module has inference enabled. * codegen: gc wb for atomic FCA stores (#58792) Need to re-load the correct `r` since issetfield skips the intcast, resulting in no gc wb for the FCA. Fix #58760 * codegen: relaxed jl_tls_states_t.safepoint load (#58828) Every function with a safepoint causes spurious thread sanitizer warnings without this change. Codegen is unaffected, except when we build with `ThreadSanitizerPass`. * bpart: Properly track methods with invalidated source after require_world (#58830) There are three categories of methods we need to worry about during staticdata validation: 1. New methods added to existing generic functions 2. New methods added to new generic functions 3. Existing methods that now have new CodeInstances In each of these cases, we need to check whether any of the implicit binding edges from the method's source was invalidated. Currently, we handle this for 1 and 2 by explicitly scanning the method on load. However, we were not tracking it for case 3. Fix that by using an extra bit in did_scan_method that gets set when we see an existing method getting invalidated, so we know that we need to drop the corresponding CodeInstances during load. Fixes #58346 * Limit --help and --help-hidden to 100 character line length (#58835) Just fixing the command line description to make sure it is not more than 100 characters wide as discussed with @oscardssmith in PR #54066 and PR #53759. I also added a test to make sure that nothing more than 100 characters is inserted. Thank you. * libuv: Mark `(un)preserve_handle` as `@nospecialize` (#58844) These functions only worry about object identity, so there's no need for them to specialize them on their type. * add METHOD_SIG_LATEST_ONLY optimization to MethodInstance too (#58825) Add the same optimization from Method to MethodInstance, although the performance gain seems to be negligible in my specific testing, there doesn't seem any likely downside to adding one caching bit to avoid some recomputations. * Encode fully_covers=false edges using negative of method count This change allows edges that don't fully cover their method matches to be properly tracked through serialization. When fully_covers is false (indicating incomplete method coverage), we encode the method count as negative in the edges array to signal that compactly. * move trim patches to separate files, only load if trimming (#58826) fixes part of #58458 * gf: Add METHOD_SIG_LATEST_HAS_NOTMORESPECIFIC dispatch status bit This commit introduces a new dispatch status bit to track when a method has other methods that are not more specific than it, enabling better optimization decisions during method dispatch. Key changes: 1. Add METHOD_SIG_LATEST_HAS_NOTMORESPECIFIC bit to track methods with non-morespecific intersections 2. Add corresponding METHOD_SIG_PRECOMPILE_HAS_NOTMORESPECIFIC bit for precompiled methods 3. Refactor method insertion logic: - Remove morespec_unknown enum state, compute all morespec values upfront - Convert enum morespec_options to simple boolean logic (1/0) - Change 'only' from boolean to 'dispatch_bits' bitmask - Move dispatch status updates before early continues in the loop * optimize verify_call again * juliac: Add rudimentary Windows support (#57481) This was essentially working as-is, except for our reliance on a C compiler.

We want to compile a subset of the possible specializations of a function. To this end, we have a number of manually written `precompile` statements. Creating this list is, unfortunately, error-prone, and the list is also liable to going stale. Thus we'd like to validate each `precompile` statement in the list. The simple answer is, of course, to actually run the `precompile`s, and we naturally do so, but this takes time. We would like a relatively quick way to check the validity of a `precompile` statement. This is a dev-loop optimization, to allow us to check "is-precompilable" in unit tests. We can't use `hasmethod` as it has both false positives (too loose): ```julia julia> hasmethod(sum, (AbstractVector,)) true julia> precompile(sum, (AbstractVector,)) false julia> Base.isprecompilable(sum, (AbstractVector,)) # <- this PR false ``` and also false negatives (too strict): ```julia julia> bar(@nospecialize(x::AbstractVector{Int})) = 42 bar (generic function with 1 method) julia> hasmethod(bar, (AbstractVector,)) false julia> precompile(bar, (AbstractVector,)) true julia> Base.isprecompilable(bar, (AbstractVector,)) # <- this PR true ``` We can't use `hasmethod && isconcretetype` as it has false negatives (too strict): ```julia julia> has_concrete_method(f, argtypes) = all(isconcretetype, argtypes) && hasmethod(f, argtypes) has_concrete_method (generic function with 1 method) julia> has_concrete_method(bar, (AbstractVector,)) false julia> has_concrete_method(convert, (Type{Int}, Int32)) false julia> precompile(convert, (Type{Int}, Int32)) true julia> Base.isprecompilable(convert, (Type{Int}, Int32)) # <- this PR true ``` `Base.isprecompilable` is essentially `precompile` without the actual compilation. * Add a `similar` method for `Type{<:CodeUnits}` (#57826) Currently, `similar(::CodeUnits)` works as expected by going through the generic `AbstractArray` method. However, the fallback method hit by `similar(::Type{<:CodeUnits}, dims)` does not work, as it assumes the existence of a constructor that accepts an `UndefInitializer`. This can be made to work by defining a corresponding `similar` method that returns an `Array`. One could make a case that this is a bugfix since it was arguably a bug that this method didn't work given that `CodeUnits` is an `AbstractArray` subtype and the other `similar` methods work. If anybody buys that argument, it could be nice to backport this; it came up in some internal code that uses Arrow.jl and JSON3.jl together. * 🤖 [master] Bump the Pkg stdlib from e3d456127 to 109eaea66 (#58858) Stdlib: Pkg URL: https://github.com/JuliaLang/Pkg.jl.git Stdlib branch: master Julia branch: master Old commit: e3d456127 New commit: 109eaea66 Julia version: 1.13.0-DEV Pkg version: 1.13.0 Bump invoked by: @KristofferC Powered by: [BumpStdlibs.jl](https://github.com/JuliaLang/BumpStdlibs.jl) Diff: https://github.com/JuliaLang/Pkg.jl/compare/e3d4561272fc029e9a5f940fe101ba4570fa875d...109eaea66a0adb0ad8fa497e64913eadc2248ad1 ``` $ git log --oneline e3d456127..109eaea66 109eaea66 Various app improvements (#4278) 25c2390ed feat(apps): Add support for multiple apps per package via submodules (#4277) c78b40b35 copy the app project instead of wrapping it (#4276) d2e61025b Fix leading whitespace in REPL commands with comma-separated packages (#4274) e02bcabd7 Registry: Properly pass down `depot` (#4268) e9a055240 fix what project file to look at when package without path but with a subdir is devved by name (#4271) 8b1f0b9ff prompt for confirmation before removing compat entry (#4254) eefbef649 feat(errors): Improve error message for incorrect package UUID (#4270) 4d1c6b0a3 explain no reg installed when no reg installed (#4261) ``` Co-authored-by: KristofferC <[email protected]> * fix a few tiny JET linter issues (#58869) * Fix data race in jl_new_module__ (#58880) Use an atomic fetch and add to fix a data race in `Module()` identified by tsan: ``` ./usr/bin/julia -t4,0 --gcthreads=1 -e 'Threads.@threads for i=1:100 Module() end' ================== WARNING: ThreadSanitizer: data race (pid=5575) Write of size 4 at 0xffff9bf9bd28 by thread T9: #0 jl_new_module__ /home/user/c/julia/src/module.c:487:22 (libjulia-internal.so.1.13+0x897d4) #1 jl_new_module_ /home/user/c/julia/src/module.c:527:22 (libjulia-internal.so.1.13+0x897d4) #2 jl_f_new_module /home/user/c/julia/src/module.c:649:22 (libjulia-internal.so.1.13+0x8a968) #3 <null> <null> (0xffff76a21164) #4 <null> <null> (0xffff76a1f074) #5 <null> <null> (0xffff76a1f0c4) #6 _jl_invoke /home/user/c/julia/src/gf.c (libjulia-internal.so.1.13+0x5ea04) #7 ijl_apply_generic /home/user/c/julia/src/gf.c:3892:12 (libjulia-internal.so.1.13+0x5ea04) #8 jl_apply /home/user/c/julia/src/julia.h:2343:12 (libjulia-internal.so.1.13+0x9e4c4) #9 start_task /home/user/c/julia/src/task.c:1249:19 (libjulia-internal.so.1.13+0x9e4c4) Previous write of size 4 at 0xffff9bf9bd28 by thread T10: #0 jl_new_module__ /home/user/c/julia/src/module.c:487:22 (libjulia-internal.so.1.13+0x897d4) #1 jl_new_module_ /home/user/c/julia/src/module.c:527:22 (libjulia-internal.so.1.13+0x897d4) #2 jl_f_new_module /home/user/c/julia/src/module.c:649:22 (libjulia-internal.so.1.13+0x8a968) #3 <null> <null> (0xffff76a21164) #4 <null> <null> (0xffff76a1f074) #5 <null> <null> (0xffff76a1f0c4) #6 _jl_invoke /home/user/c/julia/src/gf.c (libjulia-internal.so.1.13+0x5ea04) #7 ijl_apply_generic /home/user/c/julia/src/gf.c:3892:12 (libjulia-internal.so.1.13+0x5ea04) #8 jl_apply /home/user/c/julia/src/julia.h:2343:12 (libjulia-internal.so.1.13+0x9e4c4) #9 start_task /home/user/c/julia/src/task.c:1249:19 (libjulia-internal.so.1.13+0x9e4c4) Location is global 'jl_new_module__.mcounter' of size 4 at 0xffff9bf9bd28 (libjulia-internal.so.1.13+0x3dbd28) ``` * fix trailing indices stackoverflow in reinterpreted array (#58293) would fix https://github.com/JuliaLang/julia/issues/57170, fix https://github.com/JuliaLang/julia/issues/54623 @nanosoldier `runbenchmarks("array", vs=":master")` * Add missing module qualifier (#58877) A very simple fix addressing the following bug: ```julia Validation: Error During Test at REPL[61]:1 Got exception outside of a @test #=ERROR showing exception stack=# UndefVarError: `get_ci_mi` not defined in `Base.StackTraces` Suggestion: check for spelling errors or missing imports.

It's been around since 1.8 (see also: #55773) and I think we should commit to keeping it functional for the rest of 1.x. * Add link to video in profiling manual (#58896) * Stop documenting that `permute!` is "in-place"; it isn't and never has been non-allocating (#58902) * faster iteration over a `Flatten` of heterogenous iterators (#58522) seems to help in many cases. would fix the precise MWE given in https://github.com/JuliaLang/julia/issues/52552, but does not necessarily fix comprehensively all perf issues of all heterogenous flattens. but, may as well be better when it's possible setup: ``` julia> using BenchmarkTools julia> A = rand(Int, 100000); B = 1:100000; julia> function g(it) s = 0 for i in it s += i end s end ``` before: ``` julia> @btime g($(Iterators.flatten((A, B)))) 12.461 ms (698979 allocations: 18.29 MiB) julia> @btime g($(Iterators.flatten(i for i in (A, B)))) 12.393 ms (698979 allocations: 18.29 MiB) julia> @btime g($(Iterators.flatten([A, B]))) 15.115 ms (999494 allocations: 25.93 MiB) julia> @btime g($(Iterators.flatten((A, Iterators.flatten((A, B)))))) 82.585 ms (2997964 allocations: 106.78 MiB) ``` after: ``` julia> @btime g($(Iterators.flatten((A, B)))) 135.958 μs (2 allocations: 64 bytes) julia> @btime g($(Iterators.flatten(i for i in (A, B)))) 149.500 μs (2 allocations: 64 bytes) julia> @btime g($(Iterators.flatten([A, B]))) 17.130 ms (999498 allocations: 25.93 MiB) julia> @btime g($(Iterators.flatten((A, Iterators.flatten((A, B)))))) 13.716 ms (398983 allocations: 10.67 MiB) ``` * Make `hypot` docs example more type stable (#58918) * Markdown: Make `Table`/`LaTeX` objects subtypes of `MarkdownElement` (#58916) These objects satisfy the requirements of the `MarkdownElement` interface (such as implementing `Markdown.plain`), so they should be subtypes of `MarkdownElement`. This is convenient when defining functions for `MarkdownElement` in other packages. * Support "Functor-like" `code_typed` invocation (#57911) This lets you easily inspect IR associated with "Functor-like" methods: ```julia julia> (f::Foo)(offset::Float64) = f.x + f.y + offset julia> code_typed((Foo, Float64)) 1-element Vector{Any}: CodeInfo( 1 ─ %1 = Base.getfield(f, :x)::Int64 │ %2 = Base.getfield(f, :y)::Int64 │ %3 = Base.add_int(%1, %2)::Int64 │ %4 = Base.sitofp(Float64, %3)::Float64 │ %5 = Base.add_float(%4, offset)::Float64 └── return %5 ) => Float64 ``` This is just a small convenience over `code_typed_by_type`, but I'm in support of it (even though it technically changes the meaning of, e.g., `code_typed((1, 2))` which without this PR inspects `(::Tuple{Int,Int})(::Vararg{Any})` We should probably update all of our reflection machinery (`code_llvm`, `code_lowered`, `methodinstance`, etc.) to support this "non-arg0" style as well, but I wanted to open this first to make sure folks like it. * IRShow: Print arg0 type when necessary to disambiguate `invoke` (#58893) When invoking any "functor-like", such as a closure: ```julia bar(x) = @noinline ((y)->x+y)(x) ``` our IR printing was not showing the arg0 invoked, even when it is required to determine which MethodInstance this is invoking. Before: ```julia julia> @code_typed optimize=true bar(1) CodeInfo( 1 ─ %1 = %new(var"#bar##2#bar##3"{Int64}, x)::var"#bar##2#bar##3"{Int64} │ %2 = invoke %1(x::Int64)::Int64 └── return %2 ) => Int64 ``` After: ```julia julia> @code_typed optimize=true bar(1) CodeInfo( 1 ─ %1 = %new(var"#bar##2#bar##3"{Int64}, x)::var"#bar##2#bar##3"{Int64} │ %2 = invoke (%1::var"#bar##2#bar##3"{Int64})(x::Int64)::Int64 └── return %2 ) => Int64 ``` * Support "functors" for code reflection utilities (#58891) As a follow-up to https://github.com/JuliaLang/julia/pull/57911, this updates: - `Base.method_instance` - `Base.method_instances` - `Base.code_ircode` - `Base.code_lowered` - `InteractiveUtils.code_llvm` - `InteractiveUtils.code_native` - `InteractiveUtils.code_warntype` to support "functor" invocations. e.g. `code_llvm((Foo, Int, Int))` which corresponds to `(::Foo)(::Int, ::Int)` * Prevent data races in invalidate_code_for_globalref! * Fix type instability in invalidate_code_for_globalref! * Add the fact that functions ending with `!` may allocate to the FAQ (#58904) I've run into this question several times, that might count as "frequently asked". * Economy mode REPL: run the event loop with jl_uv_flush (#58926) `ios_flush` won't wait for the `jl_static_show` from the previous evaluation to complete, resulting in the output being interleaved with subsequent REPL outputs. Anything that produces a lot of output will trigger it, like `Core.GlobalMethods.defs`. * Fix grammar, typos, and formatting issues in docstrings (#58944) Co-authored-by: Claude <[email protected]> * Fix nthreadpools size in JLOptions (#58937) * NFC: Remove duplicate `julia-src-%` dependency in makefile (#58947) * Improve error message for missing dependencies in packages (#58878) * Make current_terminfo a OncePerProcess (#58854) There seems to be no reason to always load this unconditionally - especially since it's in the critical startup path. If we never print colored output or our IO is not a TTY, we don't need to load this at all. While we're at it, remove the `term_type` argument to `ttyhascolor`, which didn't work as advertised anyway, since it still looked at the current_terminfo. If clients want to do a full TermInfo check, they can do that explicitly.

We were accidentally discarding inferred code during staticdata preparation that we would need immediately afterwards to satisfy inlining requests during code generation for the system image. This was resulting in spurious extra compilation at the first inference after sysimage reload. Additionally it was likely causing various unnecessary dispatch slow paths in the generated inference code. Fixes #58841. * clear up `isdone` docstring (#58958) I got pretty confused on my first reading of this docstring because for some reason I thought it was saying that `isdone(itr, state) == missing` implied that it was true that `iterate(itr, state) === nothing` (aka that `state` is indeed final). which of course is wrong and doesn't make sense, but it's still how I read it. I think the new docstring is a bit more explicit. * shield `_artifact_str` function behind a world age barrier (#58957) We already do this for `require` in Base loading, it probably makes sense to do this here as well, as invalidating this function easily adds +1s in load time for a jll. Avoids the big load time penalty from loading IntelOpenMP_jll in https://github.com/JuliaLang/julia/issues/57436#issuecomment-3052258775.

As discussed on slack, any `hygienic-scope` within an outer `hygienic-scope` can read and write variables in the outer one, so it's not particularly hygienic. The result is that we can't safely nest macro calls unless they know the contents of all inner macro calls. Should fix #48910. Co-authored-by: Michiel Dral <[email protected]> * remove comment from julia-syntax that is no longer true (#58964) The code this referred to was removed by c6c3d72d1cbddb3d27e0df0e739bb27dd709a413 * expand memoryrefnew capabilities (#58768) The goal here is 2-fold. Firstly, this should let us simplify the boundscheck (not yet implimented), but this also should reduce Julia IR side a bit. * Add news entry and update docstring for #58727 (#58973) * Fix alignment of failed precompile jobs on CI (#58971) * bpart: Tweak `isdefinedglobal` on backdated constant (#58976) In d2cc06193ef4161e4ac161bd4b5b57a51686a89a and prior commits, we made backdated access a conditional error (if depwarns are enabled or in generators). However, we did not touch `isdefinedglobal`. This resulted in the common pattern `isdefinedglobal(m, s) && getglobal(m, s)` to sometimes error. In particular, this could be observed when attempting to print a type from inside a generated function before that type's definition age. Additionally, I think the usage there, which used `invokelatest` on each of the two queries is problematic because it is racy, since the two `invokelatest` calls may be looking at different world ages. This makes two tweaks: 1. Makes `isdefinedglobal` consistent with `getglobal` in that it now returns false if `getglobal` would throw due to the above referenced restriction. 2. Removes the implicit `invokelatest` in _isself in the show code. Instead, it will use the current world. I considered having it use the exception age when used for MethodErrors. However, because this is used for printing it matters more how the object can be accessed *now* rather than how it could have been accessed in the past. * Fix precompilepkgs warn loaded setting (#58978) * specify that `Iterators.rest` must be given a valid `state` (#58962) ~currently `Iterators.rest(1:2, 3)` creates an infinite loop. after this PR it would be an `ArgumentError`~ docs only now * stdlib/Dates: Fix doctest regex to handle DateTime with 0 microseconds (#58981) The `now(UTC)` doctest can fail when the DateTime has exactly 0 milliseconds, as the output format omits the fractional seconds entirely (e.g., "2023-01-04T10:52:24" instead of "2023-01-04T10:52:24.000"). Update the regex filter to make the milliseconds portion optional by using `(\\.\\d{3})?` instead of `\\.\\d{3}`.

As a consequence, ```julia julia> struct MyStepRangeLen{T,R} <: AbstractRange{T} x :: R end julia> MyStepRangeLen(s::StepRangeLen{T}) where {T} = MyStepRangeLen{T,typeof(s)}(s) MyStepRangeLen julia> Base.first(s::MyStepRangeLen) = first(s.x) julia> Base.last(s::MyStepRangeLen) = last(s.x) julia> Base.length(s::MyStepRangeLen) = length(s.x) julia> Base.step(s::MyStepRangeLen) = step(s.x) julia> r = MyStepRangeLen(StepRangeLen(1,0,4)) 1:0:1 julia> unique(r) ERROR: MethodError: Cannot `convert` an object of type Vector{Int64} to an object of type MyStepRangeLen{Int64, Int64, StepRangeLen{Int64, Int64, Int64, Int64}} [...] ``` This PR fixes this by using constructing a `UnitRange` instead of the indexing operation. After this, we obtain ```julia julia> unique(r) 1:1:1 ``` In principle, the `step` should be preserved, but `range(r[begin]::Int, step=step(r), length=length(r))` appears to error at present, as it tries to construct a `StepRange` instead of a `StepRangeLen`. This fix isn't perfect as it assumes that the conversion from a `UnitRange` _is_ defined, which is also not the case by default. For example, the following still won't work: ```julia julia> struct MyRange <: AbstractRange{Int} end julia> Base.first(x::MyRange) = 1 julia> Base.last(x::MyRange) = 1 julia> Base.length(x::MyRange) = 3 julia> Base.step(x::MyRange) = 0 julia> unique(MyRange()) ERROR: MethodError: no method matching MyRange(::UnitRange{Int64}) [...] ``` In fact, if the indexing `MyRange()[begin:begin]` has been specialized but the conversion from a `UnitRange` isn't, then this is actually a regression. I'm unsure if such pathological cases are common, though. The reason the first example works is that the conversion for a range wrapper is defined implicitly if the parent type supports conversion from a `UnitRange`. * Docs: add GC user docs (#58733) Co-authored-by: Andy Dienes <[email protected]> Co-authored-by: Gabriel Baraldi <[email protected]> Co-authored-by: Diogo Netto <[email protected]> * 🤖 [master] Bump the Pkg stdlib from 109eaea66 to b85e29428 (#58991) Co-authored-by: IanButterworth <[email protected]> * Add one-argument `argtypes` methods to source reflection functions (#58925) Follow-up to https://github.com/JuliaLang/julia/pull/58891#issuecomment-3036419509, extending the feature to `which`, `functionloc`, `edit` and `less`. * Test: Add compiler hint for `ts` variable definedness in `@testset for` (#58989) Helps the new language server avoid reporting unused variable reports. * trimming: explictly add Libdl dep for test/trimming/basic_jll.jl (#58990) * win/msys2: Automatically switch msys2 symlinks mode for LLVM (#58988) As noted in https://github.com/JuliaLang/julia/issues/54981#issuecomment-2336444226, msys2 currently fails to untar an llvm source build. Fix that by setting the appropriate environment variable to switch the symlinks mode. * Fix order of MSYS rules (#58999) git-external changes the LLVM_SRC_DIR variable, so the target-specific variable applies to the wrong target if defined before it - didn't notice in local testing because I had accidentally switched the variable globally earlier for testing - but showed up on a fresh build. * msys2: Recommend correct cmake package (#59001) msys2 ships 2 different cmake packages, one built natively (with mingw prefix in the package name) and one built against the posix emulation environment. The posix emulation one does not work because it will detect unix-style paths, which it then writes into files that native tools process. Unlike during command invocation (where the msys2 runtime library does path translation), when paths are written to files, they are written verbatim. The practical result of this is that e.g. the LLVM build will fail with a mysterious libz link failure (as e.g. reported in #54981). This is our fault, because our built instructions tell the user to install the wrong one. Fix all that by 1. Correcting the build instructions to install the correct cmake 2. Detecting if the wrong cmake is installed and advising the correct one 3. Fixing an issue where the native CMake did not like our CMAKE_C_COMPILER setting. With all this, CMake runs correctly under msys2 with USE_BINARYBUILDER_LLVM=0. * feat(REPL): Added `active_module` context to numbered REPL (#59000) * optimize `length(::OrdinalRange)` for large bit-ints (#58864) Split from #58793, this coalesces nearly all the branches in `length`, allowing it to inline and generally perform much better while retaining the exact same functionality. --------- Co-authored-by: N5N3 <[email protected]> * Fix LLVM TaskDispatcher implementation issues (#58950) Fixes #58229 (LLVM JITLink stack overflow issue) I tried submitting this promise/future implementation upstream (https://github.com/llvm/llvm-project/compare/main...vtjnash:llvm-project:jn/cowait-jit) so that I would not need to duplicate nearly as much code here to fix this bug, but upstream is currently opposed to fixing this bug and instead insists it is preferable for each downstream project to implement this fix themselves adding extra maintenance burden for us for now.

The root cause is that uv_fseventscb_file called uvfinalize earlier, but did not set the handle to NULL, so when the actual finalizer ran later, it would see corrupted state. * Roll up msys2/clang/windows build fixes (#59003) This rolls up everything I had to change to get a successful source build of Julia under msys2.

This provides significant performance improvements: - Replace method comparisons with precomputed interference lookup. - Optimize ml_matches minmax computation using interference lookups. - Optimize sort_mlmatches for large return sets by iterating over interferences instead of all matching methods. - Add method_morespecific_via_interferences in both C and Julia. This representation may exclude some edges that are implied by transitivity since sort_mlmatches will ensure the correct result by following strong edges. Ambiguous edges are guaranteed to be checkable without recursion. Also fix a variety of bugs along the way: - Builtins signature would cause them to try to discard all other methods during `sort_mlmatches`. - Some ambiguities were over-estimated, which now are improved upon. - Setting lim==-1 now gives the same limited list of methods as lim>0, since that is actually faster now than attempting to give the unsorted list. This provides a better fix to #53814 than #57837 and fixes #58766. - Reverts recent METHOD_SIG_LATEST_HAS_NOTMORESPECIFIC attempt (though not the whole commit), since I found a significant problem with any usage of that bit during testing: it only tracks methods that intersect with a target, but new methods do not necessarily intersect with any existing target. This provides a decent performance improvement to `methods` calls, which implies a decent speed up to package loading also (e.g. ModelingToolkit loads in about 4 seconds instead of 5 seconds). * build/llvm: Remove bash-specific curly expansion (#59058) Fixes #59050 * build: More msys2 fixes (#59028) * remove a testset from MMAP that might cause CI to now fail on Windows (#59062) * Use a dedicated parameter attribute to identify the gstack arg. (#59059) Otherwise, on systems without SwitfCC support (i.e. RISC-V) `getPGCstack` may return null, disabling the final GC pass. * skip unnecessary alias-check in `collect(::AbstractArray)` from `copyto!` (#55748) As discussed on Slack with @MasonProtter & @jakobnissen, `collect` currently does a usually cheap - but sometimes expensive - aliasing check (via `unalias`->`mightalias`->`dataid` -> `objectid`) before copying contents over; this check is unnecessary, however, since the source array is newly created and cannot possibly alias the input. This PR fixes that by swapping from `copyto!` to `copyto_unaliased!` in the `_collect_indices` implementations where the swap is straightforward (e.g., it is not so straightforward for the fallback `_collect_indices(indsA, A)`, so I skipped it there). This improves the following example substantially: ```jl struct GarbageVector{N} <: AbstractVector{Int} v :: Vector{Int} garbage :: NTuple{N, Int} end GarbageVector{N}(v::Vector{Int}) where N = GarbageVector{N}(v, ntuple(identity, Val(N))) Base.getindex(gv::GarbageVector, i::Int) = gv.v[i] Base.size(gv::GarbageVector) = size(gv.v) using BenchmarkTools v = rand(Int, 10) gv = GarbageVector{100}(v) @btime collect($v); # 30 ns (v1.10.4) -> 30 ns (PR) @btime collect($gv); # 179 ns (v1.10.4) -> 30 ns (PR) ``` Relatedly, it seems the fact that `mightalias` is comparing immutable contents as well - and hence slowing down the `unalias` check for the above `GarbageVector` via a slow `objectid` on tuples - is suboptimal. I don't know how to fix that though, so I'd like to leave that outside this PR.

(#59080) On QEMU's RISC-V cpu, LLVM's `getHostCPUFeatures` reports: ``` +zksed,+zkne,+zksh,+zfh,+zfhmin,+zacas,+v,+f,+c,+zvknha,+a,+zfa,+ztso,+zicond,+zihintntl,+zvbb,+zvksh,+zvkg,+zbkb,+zvkned,+zvbc,+zbb,+zvfhmin,+zbkc,+d,+i,+zknh,+zicboz,+zbs,+zvksed,+zbc,+zba,+zvknhb,+zknd,+zvkt,+zbkx,+zkt,+zvfh,+zvkb,+m ``` We change that to: ``` +zksed,+zkne,+zksh,+zfh,+zfhmin,+zacas,+v,+f,+c,+zvknha,+a,+zfa,+ztso,+zicond,+zihintntl,+zvbb,+zvksh,+zvkg,+zbkb,+zvkned,+zvbc,+zbb,+zvfhmin,+zbkc,+d,+i,+zknh,+zicboz,+zbs,+zvksed,+zbc,+zba,+zvknhb,+zknd,+zvkt,+zbkx,+zkt,+zvfh,+zvkb,+m,-zcmop,-zca,-zcd,-zcb,-zve64d,-zve64x,-zve64f,-zawrs,-zve32x,-zimop,-zihintpause,-zcf,-zve32f ``` i.e. we add `-zcmop,-zca,-zcd,-zcb,-zve64d,-zve64x,-zve64f,-zawrs,-zve32x,-zimop,-zihintpause,-zcf,-zve32f`, disabling stuff `zve*` after first enabling `v` (which includes `zvl*b`). That's not valid: ``` LLVM ERROR: 'zvl*b' requires 'v' or 'zve*' extension to also be specified ``` ... so disable this post-processing of LLVM feature sets and trust what it spits out. AFAICT this only matters for the fallback path of `processor.cpp`, so shouldn't impact most users. * build: Also pass -fno-strict-aliasing for C++ (#59066) As diagnosed by Andrew Pinski (https://github.com/JuliaLang/julia/issues/58466#issuecomment-3105141193), we are not respecting strict aliasing currently. We turn this off for C, but the flag appears to be missing for C++. Looks like it's been that way ever since that flag was first added to our build system (#484). We should probably consider running TypeSanitizer over our code base to see if we can make our code correct under strict aliasing as compilers are increasingly taking advantage of it.

JuliaDiffEq and IterativeSolvers.jl have to make sure that the real-type is pulled out in order for `eps` to work: ```julia eps(real(typeof(b))) ``` This detail can make many algorithms with tolerances that are written generically that would otherwise work with complex numbers error. This PR proposes to do just that trick, so that way `eps(1.0 + 1.0im)` returns machine epsilon for a Float64 (and generally works for `AbstractFloat` of course). --------- Co-authored-by: Steven G.

If the cursor is on something that "looks like" an identifier, like a boolean or one of the keywords, treat it as if it was one for completion purposes.

In preparation for upstreaming these changes.
This ended up being a pretty large set of changes, but I think most of this would have been necessary for the upstream PR anyway.
Summary of the changes:
#ifdef MMTK_GCs.gc-interface.h.gc-common.c.gc-debug.candgc-pages.centirely for MMTk.gc.hinto 3 parts: common, MMTk-specific, and Julia GC-specific.julia.handjulia_internal.h.#ifdef MMTK_GCinllvm-pass-helpers.cpp.We can now start working on resolving the TODOs.
