Avoid deadlock caused by Cocoa code taking the ROOT lock
fe17c1f 
In the example below, thread #11 is waiting on the ‘AppKit lock’ while thread #1 is waiting on the ROOT read lock and thread #12 is waiting on the ROOT write lock.

In thread #11, the ROOT write lock is taken/held by frame #9, TCanvas::Update, to ‘serialize’ the update to the windowing system.

In thread #1, the ‘AppKit lock’ is likely taken/held by a frame in the #16 to root-project#40 range.

This commit remove the dead lock by removing the unnecessary use of code needing the ROOT lock within code run under the AppKit lock so that in they case thread #1 no longer need to wait for the ROOT (read) lock.

In addition it should be investigated whether the ROOT (write) lock should be taken in thread #1, frame 1 (TMacOSXSystem::ProcessPendingEvents) for the same reason it is taken in TCanvas::Update.

Avoid deadlock caused by Cocoa code taking the ROOT lock
acf759c 
In the example below, thread #11 is waiting on the ‘AppKit lock’ while thread #1 is waiting on the ROOT read lock and thread #12 is waiting on the ROOT write lock.

In thread #11, the ROOT write lock is taken/held by frame #9, TCanvas::Update, to ‘serialize’ the update to the windowing system.

In thread #1, the ‘AppKit lock’ is likely taken/held by a frame in the #16 to #40 range.

This commit remove the dead lock by removing the unnecessary use of code needing the ROOT lock within code run under the AppKit lock so that in they case thread #1 no longer need to wait for the ROOT (read) lock.

In addition it should be investigated whether the ROOT (write) lock should be taken in thread #1, frame 1 (TMacOSXSystem::ProcessPendingEvents) for the same reason it is taken in TCanvas::Update.

Avoid deadlock caused by Cocoa code taking the ROOT lock
dde03a8 
In the example below, thread #11 is waiting on the ‘AppKit lock’ while thread #1 is waiting on the ROOT read lock and thread #12 is waiting on the ROOT write lock.

In thread #11, the ROOT write lock is taken/held by frame #9, TCanvas::Update, to ‘serialize’ the update to the windowing system.

In thread #1, the ‘AppKit lock’ is likely taken/held by a frame in the #16 to root-project#40 range.

This commit remove the dead lock by removing the unnecessary use of code needing the ROOT lock within code run under the AppKit lock so that in they case thread #1 no longer need to wait for the ROOT (read) lock.

In addition it should be investigated whether the ROOT (write) lock should be taken in thread #1, frame 1 (TMacOSXSystem::ProcessPendingEvents) for the same reason it is taken in TCanvas::Update.

Avoid deadlock caused by Cocoa code taking the ROOT lock
c2e3a62 
In the example below, thread #11 is waiting on the ‘AppKit lock’ while thread #1 is waiting on the ROOT read lock and thread #12 is waiting on the ROOT write lock.

In thread #11, the ROOT write lock is taken/held by frame #9, TCanvas::Update, to ‘serialize’ the update to the windowing system.

In thread #1, the ‘AppKit lock’ is likely taken/held by a frame in the #16 to #40 range.

This commit remove the dead lock by removing the unnecessary use of code needing the ROOT lock within code run under the AppKit lock so that in they case thread #1 no longer need to wait for the ROOT (read) lock.

In addition it should be investigated whether the ROOT (write) lock should be taken in thread #1, frame 1 (TMacOSXSystem::ProcessPendingEvents) for the same reason it is taken in TCanvas::Update.

Work-around cling::Interpreter::compileFunction getting confused by t…
afd28c4 
…railing transactions.

With the current code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.

The work-around is to avoid the need for the transaction by marking the class
TGlobal has been guaranteed to have a proper Hash vs RecursiveRemove setup
thus avoid the need to check it at run-time (by JIT code)

Reproducer:

With a main composed of 'only':

int main(int argc, char ** argv)
{
  char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;
}

which is a representation of real use case (in a more complex setup) in ART.
We were getting:

Error in <TClingCallFunc::make_wrapper>: Failed to compile
  ==== SOURCE BEGIN ====
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wformat-security"
__attribute__((used)) extern "C" void __cf_0(void* obj, int nargs, void** args, void* ret)
{
   if (ret) {
      (*(TStreamerInfo**)ret) = new TStreamerInfo();
      return;
   }
   else {
      new TStreamerInfo();
      return;
   }
}
#pragma clang diagnostic pop
  ==== SOURCE END ====
Error in <TClingCallFunc::ExecT>: Called with no wrapper, not implemented!
Error in <TVirtualStreamerInfo::Factory>: The plugin handler for TVirtualStreamerInfo was found but failed to create the factory object!

The reason is that during TClingCallFunc::make_wrapper, the call to cling::Interpreter::compileFunction ends with:

    if (const llvm::GlobalValue* GV
        = getLastTransaction()->getModule()->getNamedValue(name))

However in the 'broken' case, the getLastTransaction does not return the transaction for the code being compiled by DeclareCFunction but instead the one used/created at:

The work-around is to avoid the need for the transaction by marking the class
TGlobal has been guaranteed to have a proper Hash vs RecursiveRemove setup

Reproducer:

With a main composed of 'only':

  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;

which is a representation of real use case (in a more complex setup) in ART.

Work-around cling::Interpreter::compileFunction getting confused by t…
3fcf140 
…railing transactions.

This fixes https://sft.its.cern.ch/jira/browse/ROOT-9672

With the current code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.

The work-around is to avoid the need for the transaction by marking the class
TGlobal has been guaranteed to have a proper Hash vs RecursiveRemove setup
thus avoid the need to check it at run-time (by JIT code)

Reproducer:

With a main composed of 'only':

int main(int argc, char ** argv)
{
  char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;
}

which is a representation of real use case (in a more complex setup) in ART.
We were getting:

Work-around cling::Interpreter::compileFunction getting confused by t…
683aed4 
…railing transactions.

This fixes https://sft.its.cern.ch/jira/browse/ROOT-9672

With the current code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.

The work-around is to avoid the need for the transaction by marking the class
TGlobal has been guaranteed to have a proper Hash vs RecursiveRemove setup
thus avoid the need to check it at run-time (by JIT code)

Reproducer:

With a main composed of 'only':

int main(int argc, char ** argv)
{
  char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;
}

which is a representation of real use case (in a more complex setup) in ART.
We were getting:

#pragma clang diagnostic ignored "-Wformat-security"

      (*(TStreamerInfo**)ret) = new TStreamerInfo();
      return;
   }
   else {
      new TStreamerInfo();
      return;
   }
}

  ==== SOURCE END ====

The reason is that during TClingCallFunc::make_wrapper, the call to cling::Interpreter::compileFunction ends with:

    if (const llvm::GlobalValue* GV
        = getLastTransaction()->getModule()->getNamedValue(name))

However in the 'broken' case, the getLastTransaction does not return the transaction for the code being compiled by DeclareCFunction but instead the one used/created at:

Fix cling::Interpreter::compileFunction getting confused by trailing …
8109495 
…transactions.

This fixes https://sft.its.cern.ch/jira/browse/ROOT-9672 by having
cling::Interpreter::DeclareCFunction return the transaction containing the
compiled code.

With the previous code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.

Reproducer:

With a main composed of 'only':

int main(int argc, char ** argv)
{
  char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;
}

which is a representation of real use case (in a more complex setup) in ART.
We were getting:

However in the 'broken' case, the getLastTransaction does not return the transaction for the code being compiled by DeclareCFunction but instead the one used/created at:

Fix cling::Interpreter::compileFunction getting confused by trailing …
1ad7538 
…transactions.

This fixes https://sft.its.cern.ch/jira/browse/ROOT-9672 by having
cling::Interpreter::DeclareCFunction return the transaction containing the
compiled code.

With the previous code, cling::Interpreter::compileFunction will get confused by
transaction created during the callbacks executed during the
cling::IncrementalParser::commitTransaction of the main transaction.

Reproducer:

With a main composed of 'only':

int main(int argc, char ** argv)
{
  char const * class_string = (argc == 2) ? argv[1] : "std::vector<int>";
  auto const result [[gnu::unused]] = TClass::GetClass(class_string);
  return 0;
}

which is a representation of real use case (in a more complex setup) in ART.
We were getting:

Error in <TClingCallFunc::make_wrapper>: Failed to compile
  ==== SOURCE BEGIN ====
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wformat-security"
__attribute__((used)) extern "C" void __cf_0(void* obj, int nargs, void** args, void* ret)
{
   if (ret) {
      (*(TStreamerInfo**)ret) = new TStreamerInfo();
      return;
   }
   else {
      new TStreamerInfo();
      return;
   }
}
#pragma clang diagnostic pop
  ==== SOURCE END ====
Error in <TClingCallFunc::ExecT>: Called with no wrapper, not implemented!
Error in <TVirtualStreamerInfo::Factory>: The plugin handler for TVirtualStreamerInfo was found but failed to create the factory object!

The reason is that during TClingCallFunc::make_wrapper, the call to cling::Interpreter::compileFunction ends with:

    if (const llvm::GlobalValue* GV
        = getLastTransaction()->getModule()->getNamedValue(name))

However in the 'broken' case, the getLastTransaction does not return the transaction for the code being compiled by DeclareCFunction but instead the one used/created at:

Fix the behavior of 'rpath' option. In both cases the RPATH is always…
a68f24a 
… used for the build tree. If OFF, the RPATH is removed from the installation, otherwise the RPATH in the installation points to the install libdir.

[cling] Lifetime of MetaParser is that of its input:
3aa83e5 
Before, MetaParser might have pointed to a StringRef whose storage
was gone, see asan failure in roottest/cling/other/runfileClose.C below.

This was caused by recursive uses of MetaParser; see stack trace below:
the inner recursion returned, but as the same MetaParser object was used
by both frames, the objects cursor now pointed to freed memory.

Instead, create a MetaParser (and MetaLexer) object per input. That way,
their lifetime corresponds to the lifetime of their input.

Difficult to reduce it further due to how rootcling implicitly

cling: Add ROOT lock to LookupHelper::findType
7c1f0a0 
This fixes #18236

As seen in cms-sw/cmssw#47763 (comment)
there are cases where the ROOT global lock is taken too late:

In the stack trace below the lock is requested on frame #7 where as
it should really be (also) requested on frame #12 as soon as the
transaction is being generated.

[RFHS3] Remove mention of RapidYML backend, which is not supported.

Due to lack of time, only one RooFit backend can be supported. On CMake
configure, it, however, looked like RapidYML should be found. Here, the
corresponding YML messages and mentions throughout the documentation are
removed.
If the backend should be revived, this commit can be reverted.

Fix root-project#18128.

Introduce TObject::SavePrimitiveVector

Save array of doubles in C++ macro as std::vector<Double_t>.
Should replace in code use of SavePrimitiveArray -
while stack has limited memory and therefore plain arrays in macro can exhaust resources

Use SavePrimitiveVector for TH1/TProfile classes

Use SavePrimitiveVector in TGraph classes

Use SavePrimitiveVector for TCutG/TScatter/TEfficiency

Use SavePrimitiveVector for TF1/TF2

Use SavePrimitiveVector in TGraph2D

Use SavePrimitiveVector in TPolyLine/Mraker/3D classes

Remove SavePrimitiveArray

Was replaced by SavePrimitiveVector.
No longer used in the code, was not in released code

[ntuple] Move RNTupleView out of Experimental

[Python] Fix RDF Pythonization tests with `builtin_llvm=OFF`

On my machine, the RDF pythonization tests don't run when I build ROOT
with `builtin_llvm=OFF`. There is a crash unless I do `import numba` in
the beginning.

I guess it's not a priority to understand the underlying problem because
not many people build ROOT like this and the workaround is easy, but at
least the tests should be green.

We do the same "magically ordered imports" also in other Python tests
where ROOT doesn't work together with xgboost because of `std::regexp`
symbol clashes, unless you do the import in a certain order:

[df] Avoid bad integer substitution in string formatting

The '%lu' token used in RLoopManager::RunDataSource does not correspond
to the correct integer representation of `std::uint64_t` on all
platforms. We use a stringstream instead to construct the warning
message.

Introduce TObject::SavePrimitiveDraw method

Store typical object->Draw() invocation.
Correctly handle "nodraw" arguments in options
Also replace special symbols if option string is not empty

Use SavePrimitiveDraw in graf2d/graf classes

Improve TGraphStruct::SavePrimitive

Use new method to store constructor and attributes
Simplify loops over nodes and edges
Use fixed variable name for TGraphEdge

Use SavePrimitiveDraw in hist classes

Use SavePrimitiveDraw in other classes

Fix TPave::SavePrimitive for web case

In case when canvas created in the batch mode,
it never rendered on server side.
And thus coordinates of TPave object remains not-initialized.
But there are macros where coordinates of TPaveStats are modified.
Such modification stored in NDC coordinates and should be taken into
account when TPave stored in C macro

Adjust stressGraphics_web.ref after TPave adjustments

Now positions of stats box modified in batch stored correctly

Completely delete qt5webdisplay sources

Delete/deprecate qt5web build option

Qt5 web engine no longer works with newest JSROOT and makes no sence to support. Everybody should be able to switch to comparable qt6 version

Remove kQt5 from RWebDsiaplayArgs

It was display kind for --web=qt5 argument

Adjust tutorials/visualisation/webgui/qtweb

Only support qt6 for building this tutorial

Remove qt5 workaround in THttpServer

For usage of qt5 webengine importmap has to be emulated
Now such emulation is no longer necessary

Introduce RWebDisplayArgs::GetQtEmbedQualifier

Keep old GetQt5EmbedQualifier to backward compatibility,
but prefer to use newer approach

Use GetQtEmbedQualifier in qtweb tutorial

[Python] Correctly manage NumPy dependencey in pythonization tests

builtin "array" library.

[CPyCppyy] Drop `__array__` from std::vector pythonizations

The addition of the __array__ utility to std::vector Python proxies causes a
bug where the resulting array is a single dimension, causing loss of data when
converting to numpy arrays, for >1dim vectors. The recursive nature of this
function, passes each subarray (pydata) to the next call and only the final
buffer is cast to a lowlevel view and resized (in VectorData), resulting in
only the first 1D array to be returned. See root-project#17729

Since this C++ pythonization was added with the upgrade in 6.32, and is only
defined and used recursively, the safe option is to disable this function and
no longer add it. It is temporarily removed to prevent errors due to -Wunused-function

cling: Add ROOT lock to LookupHelper::findType

there are cases where the ROOT global lock is taken too late:

it should really be (also) requested on frame root-project#12 as soon as the
transaction is being generated.

[ntuple] Add tests and a warning for projected Real32(Quant|Trunc)

Setting a projected field to quantized or truncated works and read proper
data but it doesn't do what one would probably expect.
The projected field can correctly read values from any fields that can
be read as float, but the value range and bits of precision set on the
projected field are silently ignored (since they only make sense for
physical columns that are actually stored on disk).
To reduce confusion, we now emit a warning if a user tries to call
AddProjectedField with a quantized or truncated field.

Remove current RHist prototype

For a number of reasons, it is not what we want for the future
generation of histogram classes in ROOT:

 * It is templated on the DIMENSIONS, the PRECISION, and optional
   bin statistics. This makes it hard(er) to use for IO.
 * The RHist interface has a pointer to an abstract, polymorphic
   RHistImplBase.
 * The concrete RHistImpl is templated on the processed axis types.
 * The polymorphic pointer makes the current prototype incompatible
   with RNTuple (unless using streamer fields).
 * It also takes minutes to compile for higher dimensions because
   concrete RHistImpl have to be generated for all combinations of
   axis types, which grows exponentially.

The plan is to remove the current prototype now, in time for the
next ROOT release v6.36, and then add a new implementation after.

[cppyy] Disable warnings for invalid function casts

Some C++ functions defined in CPyCppyy are passed to CPython API, e.g.
to build Python methods that use some C++ functionality. This is done by
creating a instance of a PyMethodDef struct
(https://docs.python.org/3/c-api/structures.html#c.PyMethodDef). One
data member of this struct is of type PyCFunction
(https://docs.python.org/3/c-api/structures.html#c.PyCFunction), a
typedef of a function with signature
```
PyObject *PyCFunction(PyObject *self,
                      PyObject *args);
```
In many cases, the C++ functions that are used as the data member of the
PyMethodDef are not directly implemented as PyCFunction, thus need to be
cast. This cast is often invalid, since many of such functions do not
really respect the function signature prescribed by the API. This
pattern is actually encouraged for CPython extension implementations by
the official CPython docs
(https://docs.python.org/3/extending/extending.html#keyword-parameters-for-extension-functions).
As such, the compiler warnings that are generated becausee of the
invalid function casts, for example
```
root/bindings/pyroot/cppyy/CPyCppyy/src/Pythonize.cxx:1949:50: warning: cast from 'PyObject *(*)(PyObject *)' (aka '_object *(*)(_object *)') to 'PyCFunction' (aka '_object *(*)(_object *, _object *)') converts to incompatible function type [-Wcast-function-type-mismatch]
 1949 |         Utility::AddToClass(pyclass, "__repr__", (PyCFunction)ComplexRepr, METH_NOARGS);
```
cannot be avoided and have to be suppressed. This is also done upstream,
see wlav/CPyCppyy@33d4a6e

[tree] Reset missing proxies list when changing trees.

When changing trees while the missing value feature of RDF was in use,
the proxies for branches could not get recreated, since TTreeReader
refuses the registration when fProxiesSet == true.
This lead to the TTreeReaderValue being in a broken state.

[tree] Refactor vector of missing proxies to a set.

When running over multiple trees, the list of missing proxies in
TTreeReader will grow indefinitely. Here, it is refactored to a set,
which also shortens the code that looks up the missing proxies.

[tree] Include branch name in an error message.

Pointed out by Philippe in root-project#18259.

[tree] Make test of error messages a bit more rigid.

In debugging a UB in TTreeReaderValueBase, it would have been easier to
have an explicit note of the expected error messages of that test.
Instead of globally suppressing all errors, the three expected message
were added here.

[tree] Don't dereference a nullptr in TTreeReaderValue test.

On mac15 beta, this generated a SIGTRAP, while it was OK on all other
platforms, because the reference was never used.
But retrieving the pointer instead of dereferencing, the problem
seems to go away.

[CMake] Restore Python tutorial dependencies.

Due to a missing quote, dependencies on Mac15 beta seemed to have gotten
deleted.

[ntuple] apply I/O rules also to persistent members

[json] check if map class has dictionary

When stream directly std::map object in macro like:
```
   std::map<int,string> m;
   m[1] = "number 1";
   m[2] = "number 2";
   auto json = TBufferJSON::ToJSON(&m);
```
Real dictionary class for std::map is required.
It checked automatically when map is member of user class,
but was not checked when map object intself streamed

[json] check map dictionary also when read object

Same when write object, reading is not possible for std::map<>
object without dictionary

[json] mention GenerateDictionary for map classes in documentation

While std::map uses in TBufferJSON in documentaiton,
mention gInterpreter->GenerateDictionary

[CMake] Improve handling of RPATH options

Some improvements to the handling of RPATH options, which are necessary
on my system because I need to add a custom RPATH to make my CUDA
package from nix packages findable.

  1. Don't set CMake variables to `FALSE` if the default is `FALSE`
     already. This makes it impossible to change these variables from
     the CMake user configuration, unnecessarily taking flexibility out
     of the build system.

  2. If `rpath=ON`, ROOT adds the relative path from the binary
     directory to the lib directory to the RPATH. But it doesn't append
     it, overriding any `CMAKE_INSTALL_RPATH` that the user might set in
     the CMake configuration. This commit suggests to append instead.

  3. If `rpath=OFF`, ROOT sets `CMAKE_SKIP_INSTALL_RPATH` to `TRUE`
     without any apparent reason, again, preventing the user from
     defining the RPATH via `CMAKE_INSTALL_RPATH`. This commit suggests
     to remove that line.

[cppyy] Do not use non-C++ GCC warning

Although `bad-function-cast` is present for both Clang and GCC, on the
latter it is only used for C and Objective-C code. Using
`no-cast-function-type` seems to already disable the
PyCFunction-cast-related warnings seen with AppleClang.

[Python] Fix RDF Pythonization tests with `builtin_llvm=OFF`

On my machine, the RDF pythonization tests don't run when I build ROOT
with `builtin_llvm=OFF`. There is a crash unless I do `import numba` in

I guess it's not a priority to understand the underlying problem because
not many people build ROOT like this and the workaround is easy, but at
least the tests should be green.

We do the same "magically ordered imports" also in other Python tests
where ROOT doesn't work together with xgboost because of `std::regexp`
symbol clashes, unless you do the import in a certain order:

[Python] Correctly manage NumPy dependencey in pythonization tests

The dependency on Python libraries like NumPy needs to be declared in

builtin "array" library.

[CPyCppyy] Drop `__array__` from std::vector pythonizations

The addition of the __array__ utility to std::vector Python proxies causes a
bug where the resulting array is a single dimension, causing loss of data when
converting to numpy arrays, for >1dim vectors. The recursive nature of this
function, passes each subarray (pydata) to the next call and only the final
buffer is cast to a lowlevel view and resized (in VectorData), resulting in
only the first 1D array to be returned. See root-project#17729

Since this C++ pythonization was added with the upgrade in 6.32, and is only
defined and used recursively, the safe option is to disable this function and
no longer add it. It is temporarily removed to prevent errors due to -Wunused-function

[ntuple] Add tests and a warning for projected Real32(Quant|Trunc)

Setting a projected field to quantized or truncated works and read proper
data but it doesn't do what one would probably expect.
The projected field can correctly read values from any fields that can
be read as float, but the value range and bits of precision set on the
projected field are silently ignored (since they only make sense for
physical columns that are actually stored on disk).
To reduce confusion, we now emit a warning if a user tries to call
AddProjectedField with a quantized or truncated field.

Remove current RHist prototype

For a number of reasons, it is not what we want for the future
generation of histogram classes in ROOT:

 * It is templated on the DIMENSIONS, the PRECISION, and optional
   bin statistics. This makes it hard(er) to use for IO.
 * The RHist interface has a pointer to an abstract, polymorphic
   RHistImplBase.
 * The concrete RHistImpl is templated on the processed axis types.
 * The polymorphic pointer makes the current prototype incompatible
   with RNTuple (unless using streamer fields).
 * It also takes minutes to compile for higher dimensions because
   concrete RHistImpl have to be generated for all combinations of
   axis types, which grows exponentially.

The plan is to remove the current prototype now, in time for the
next ROOT release v6.36, and then add a new implementation after.

[cppyy] Disable warnings for invalid function casts

Some C++ functions defined in CPyCppyy are passed to CPython API, e.g.
to build Python methods that use some C++ functionality. This is done by
creating a instance of a PyMethodDef struct
(https://docs.python.org/3/c-api/structures.html#c.PyMethodDef). One
data member of this struct is of type PyCFunction
(https://docs.python.org/3/c-api/structures.html#c.PyCFunction), a
typedef of a function with signature
```
PyObject *PyCFunction(PyObject *self,
                      PyObject *args);
```
In many cases, the C++ functions that are used as the data member of the
PyMethodDef are not directly implemented as PyCFunction, thus need to be
cast. This cast is often invalid, since many of such functions do not
really respect the function signature prescribed by the API. This
pattern is actually encouraged for CPython extension implementations by
the official CPython docs
(https://docs.python.org/3/extending/extending.html#keyword-parameters-for-extension-functions).
As such, the compiler warnings that are generated becausee of the
invalid function casts, for example
```
root/bindings/pyroot/cppyy/CPyCppyy/src/Pythonize.cxx:1949:50: warning: cast from 'PyObject *(*)(PyObject *)' (aka '_object *(*)(_object *)') to 'PyCFunction' (aka '_object *(*)(_object *, _object *)') converts to incompatible function type [-Wcast-function-type-mismatch]
 1949 |         Utility::AddToClass(pyclass, "__repr__", (PyCFunction)ComplexRepr, METH_NOARGS);
```
cannot be avoided and have to be suppressed. This is also done upstream,
see wlav/CPyCppyy@33d4a6e

[tree] Reset missing proxies list when changing trees.

When changing trees while the missing value feature of RDF was in use,
the proxies for branches could not get recreated, since TTreeReader
refuses the registration when fProxiesSet == true.
This lead to the TTreeReaderValue being in a broken state.

[tree] Refactor vector of missing proxies to a set.

When running over multiple trees, the list of missing proxies in
TTreeReader will grow indefinitely. Here, it is refactored to a set,
which also shortens the code that looks up the missing proxies.

[tree] Include branch name in an error message.

Pointed out by Philippe in root-project#18259.

[tree] Make test of error messages a bit more rigid.

In debugging a UB in TTreeReaderValueBase, it would have been easier to
have an explicit note of the expected error messages of that test.
Instead of globally suppressing all errors, the three expected message
were added here.

[tree] Don't dereference a nullptr in TTreeReaderValue test.

On mac15 beta, this generated a SIGTRAP, while it was OK on all other
platforms, because the reference was never used.
But retrieving the pointer instead of dereferencing, the problem
seems to go away.

[CMake] Restore Python tutorial dependencies.

Due to a missing quote, dependencies on Mac15 beta seemed to have gotten
deleted.

   auto json = TBufferJSON::ToJSON(&m);
```
Real dictionary class for std::map is required.
It checked automatically when map is member of user class,
but was not checked when map object intself streamed

[json] check map dictionary also when read object

[CMake] Improve handling of RPATH options

Some improvements to the handling of RPATH options, which are necessary
on my system because I need to add a custom RPATH to make my CUDA
package from nix packages findable.

  1. Don't set CMake variables to `FALSE` if the default is `FALSE`
     already. This makes it impossible to change these variables from
     the CMake user configuration, unnecessarily taking flexibility out
     of the build system.

  2. If `rpath=ON`, ROOT adds the relative path from the binary
     directory to the lib directory to the RPATH. But it doesn't append
     it, overriding any `CMAKE_INSTALL_RPATH` that the user might set in
     the CMake configuration. This commit suggests to append instead.

  3. If `rpath=OFF`, ROOT sets `CMAKE_SKIP_INSTALL_RPATH` to `TRUE`
     without any apparent reason, again, preventing the user from
     defining the RPATH via `CMAKE_INSTALL_RPATH`. This commit suggests
     to remove that line.

[cppyy] Do not use non-C++ GCC warning

Although `bad-function-cast` is present for both Clang and GCC, on the
latter it is only used for C and Objective-C code. Using
`no-cast-function-type` seems to already disable the
PyCFunction-cast-related warnings seen with AppleClang.

cling: Add ROOT lock to LookupHelper::findType
6d9d29f 
This fixes #18236

As seen in cms-sw/cmssw#47763 (comment)
there are cases where the ROOT global lock is taken too late:

In the stack trace below the lock is requested on frame #7 where as
it should really be (also) requested on frame #12 as soon as the
transaction is being generated.
