Print stack traces of running processes on Linux. Also does python! Works with -fomit-frame-pointer, 32 and 64 bit. Includes DWARF/ELF parsing library.
You'll need cmake and a C++ compiler. Build/install with cmake. Eg:
cd pstack/ mkdir `hostname` cd `hostname` cmake .. make sudo make install
Support for various ELF debugging formats requires liblzma and zlib.
This is an implementation of pstack that uses the DWARF ".eh_frame" or ".debug_frame" unwind tables to do its work. I wrote it mostly out of curiosity, and maintain it because sometimes its useful.
It also includes "canal", which allows you to analyze objects in the address space, identifying their types through the stored vptrs, and cross-referencing that with the vtables found in the symbol table. This can give a quick-and-dirty histogram of live objects by type for finding memory leaks.
- Support rela for object files
- Can't do much with object files, but at least having the dump functions work would be nice.
- The manual page could do with some care and attention
- This actually works on ARM (i.e., raspi), but needs debug_frame. Apparently, ARM has its own magical sections for storing unwind information that it might be worth implementing.
- Support inlined subroutines, so we show the surrounding scopes as part of the stack trace.
