Really it's more of a test program than an example program. It's useful for benchmarking, testing with valgrind, etc. It's not built by default, but it can be built manually with: $ make -C build/temp.* examples/load_debug_info And run with: $ ./build/temp.*/examples/load_debug_info Signed-off-by: Omar Sandoval <[email protected]>

Compile-time constants have DW_AT_const_value instead of DW_AT_location. We can translate those to a value object. Signed-off-by: Omar Sandoval <[email protected]>

posix_memalign() doesn't have the restriction that the size must be a multiple of the alignment like aligned_alloc() does in C11. Signed-off-by: Omar Sandoval <[email protected]>
The only major change to the folly F14 implementation since I originally
ported it is commit 3d169f4365cf ("memory savings for F14 tables with
explicit reserve()"). That is a small improvement for small tables and a
large improvement for vector tables, which are about to be added.

The folly F14 implementation provides 3 storage policies: value, node, and vector. The default F14FastMap/F14FastSet chooses between the value and vector policies based on the value size. We currently only implement the value policy, as the node policy is easy to emulate and the vector policy would've added more complexity. This adds support for the vector policy (adding even more C abuse :) and automatically chooses the policy the same way as folly. It'd be easy to add a way to choose the policy if needed.

My work VPN is apparently closing HTTP connections prematurely, which exposed that urllib won't catch incomplete reads if copied through shutil.copyfileobj(). Check it explicitly. Signed-off-by: Omar Sandoval <[email protected]>

PyPI's RST parser apparently doesn't know the highlight directive, which snuck into the README in commit 4de147e ("Add CONTRIBUTING.rst"). Use code-block instead. Signed-off-by: Omar Sandoval <[email protected]>

We have a very old feature request to support searching for vmlinux and kernel modules in a directory specified by the user. This is useful, for example, if someone is given a vmcore and the corresponding kernel files. Now that we have the flexibility of the module and debug info options APIs, we can finally support it and add a command line option. Closes #17. Signed-off-by: Omar Sandoval <[email protected]>
