IMPALA-12643 (part 2): Fallback to safe libraries on error in
resolve_minidumps.py
Since resolve_minidumps.py's call to minidump_stackwalk can go haywire
due to bad symbols in shared libraries, this adds a fallback mechanism
where it tries again with a "safe" list of shared libraries. These are
limited to the ones that make the most difference in resolving minidumps
(libc, libstdc++, and libjvm). The list of safe libraries can be
customized via the --safe_library_list.
Testing:
- Verified that this uses the fallback on Centos 7 and resolves
the minidumps successfully.

> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 4.4.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> When looking into fixing IMPALA-11909 to enable running resolve_minidumps.py
> from finalize.sh, testing on Centos 7 showed that the minidump_stackwalk
> invocation from resolve_minidumps.py went haywire and used all the system's
> memory.
> resolve_minidumps.py is unique in processing all applicable system libraries.
> If some system library had corrupt symbols, it could cause minidump_stackwalk
> to get into an infinite loop.
> We should track down the offending library, but we should also run
> minidump_stackwalk with a limit on its memory usage to avoid using all the
> system memory.
