[Bug 65914] Re: apport-retrace -d fails with KeyError

[Hew McLachlan]

Ubuntu Edgy Eft is no longer supported, so a SRU will not be issued for
this release. Marking Edgy as Won't Fix.

Closing again, since it's fixed in Feisty.

Opening Edgy task. David, I'll consider this for a SRU.

No need for a dapper task, though, apport was introduced in Edgy.

Martin,  Would it be possible to push this fix back to dapper and edgy.  Launch 
pad is getting 10-15 crash reports per day for dapper and edgy users with 
ferefox issues.  
apport-retrace seems to work better (find more symbols) if used with a 
sources.list that points to the correct version of packages.

Thanks
David

Sorry if I committed a sin by reopening this issue.

 apport (0.29) feisty; urgency=low
 .
   * apport-retrace: Do not crash if a linked library is not a dependency.
 Closes: LP#65914
   * apport_utils.py:
 - Add test_find_file_package_diversion() selftest to check diversion
   handling.
 - find_file_package(): Check for and respect diversions.
 - Closes: LP#65917
   * debian/apport.init, test-apport, use-local: Adapt to 'crashdump-helper' -
 'crashdump' sysctl renaming in 2.6.19.
   * test-apport: Restore cwd even when failing a test.
   * problem_report.py, ProblemReport.write(): Support file-like objects as
 argument of file references to support direct reading from pipes. Add test
 case test_write_fileobj().
   * apport: Support '-' as core file argument, in which case the core will be
 read from stdin. This paves the way for using Linux 2.6.19's 'pipe
 core_pattern' feature. Bump python-problem-report dependency to = 0.29
 for this.
   * apport: Confine permissions of log file to root:adm 0640, just in case.
   * apport: Temporarily drop real u/gid to target user for the os.access()
 tests, so that normal users cannot verify the existence of a given
 inaccessible file. Add comprehensive tests to apport_utils' test suite and
 test-apport. Thanks to Kees Cook for this patch!
   * apport_utils.py, find_file_package(): Terminate fgrep options with '--' to
 avoid problems with funny file names. Thanks to Kees Cook for spotting
 this!
   * test-apport: Automatically detect whether ULIMIT_CORE is nonzero, and
 adapt tests accordingly: check that core still exists after invoking
 apport, and clean it up.
   * apport-retrace: Add new mode -g/--gdb which starts an interactive gdb
 session with the report's core dump. Add this to man/apport-retrace.1, too.
   * apport-retrace: If -c is given, completely remove the CoreDump field from
 the report instead of setting it to 'removed'.
   * test-apport: When using 'lib' mode, point APPORT_LOG_FILE to a temporary
 file. Print it if the test suite fails.
   * test-apport: Fix EXFAILure of the 'core dump works for non-writable cwds'
 test case.
   * preloadlib: Support -DPIPE_CORE mode which emulates the
 pipe-in-core_pattern mode of kernel 2.6.19.
   * test-apport: Build preload library with core piping. No more failed test
 suite checks in 'lib' mode.

This happens because

1. apport-retrace found the library file which included in libc6-i686 but 
crashed package depends on libc6, and
2. this line 'linux-gate.so.1 =  (0xe000)'

[Bug 65914] Re: apport-retrace -d fails with KeyError

[Aaron Whitehouse]

I was trying to retrace the crash log attached to Bug 65896
for the developers, but I got an error from apport-retrace.

$ apport-retrace -d
/var/crash/_usr_lib_mozilla-thunderbird_mozilla-thunderbird-bin.1000.crash
Traceback (most recent call last):
  File /usr/bin/apport-retrace, line 189, in ?
debug_dir = prepare_debugdir(report, options.cache_dir)
  File /usr/bin/apport-retrace, line 147, in prepare_debugdir
needed_deps.add((pkg, dependency_versions[pkg]))
KeyError

As an aside, I don't actually think that there is a debug ddeb for this
version of thunderbird, but I don't know if that matters.

Ran the exact same test as the reporter and with the same result.
Marking as confirmed.
