report time

the ones mentioned in extraenv)

This requires that the report has a CoreDump and an
ExecutablePath. This adds the following fields:
- Registers: Output of gdb's 'info registers' command
- Disassembly: Output of gdb's 'x/16i $pc' command
- Stacktrace: Output of gdb's 'bt full' command
- ThreadStacktrace: Output of gdb's 'thread apply all bt full' command
- StacktraceTop: simplified stacktrace (topmost 5 functions) for inline
inclusion into bug reports and easier processing
- AssertionMessage: Value of __abort_msg, if present
The optional rootdir can specify a root directory which has the
executable, libraries, and debug symbols. This does not require
chroot() or root privileges, it just instructs gdb to search for the
files there.
Raises a IOError if the core dump is invalid/truncated.

Reports can be suppressed by per-user blacklisting in
~/.apport-ignore.xml (in the real UID's home) and
/etc/apport/blacklist.d/. For environments where you are only
interested in crashes of some programs, you can also create a whitelist
in /etc/apport/whitelist.d/, everything which does not match gets
ignored then.
This requires the ExecutablePath attribute. Throws a ValueError if the

This is suitable for identifying duplicates.
For signal crashes this the concatenation of ExecutablePath, Signal
number, and StacktraceTop function names, separated by a colon. If
StacktraceTop has unknown functions or the report lacks any of those
fields, return None. In this case, you can use
crash_signature_addresses() to get a less precise duplicate signature
based on addresses instead of symbol names.
For assertion failures, it is the concatenation of ExecutablePath
and assertion message, separated by colons.
For Python crashes, this concatenates the ExecutablePath, exception
name, and Traceback function names, again separated by a colon.

j | f S( s Compute heuristic duplicate signature for a signal crash.
This should be used if crash_signature() fails, i. e. Stacktrace does
not have enough symbols.
This approach only uses addresses in the stack trace and does not rely
on symbol resolution. As we can't unwind these stack traces, we cannot
limit them to the top five frames and thus will end up with several or
many different signatures for a particular crash. But these can be
computed and synchronously checked with a crash database at the client
side, which avoids having to upload and process the full report. So on
the server-side crash database we will only have to deal with all the
equivalence classes (i. e. same crash producing a number of possible
signatures) instead of every single report.
Return None when signature cannot be determined.

This can be used for building duplicate signatures from non-symbolic
stack traces. These often do not have enough symbols available to
resolve function names, but taking the raw addresses also is not
suitable due to ASLR. But the offsets within a library should be
constant between crashes (assuming the same version of all libraries).
This needs and uses the "ProcMaps" field to resolve addresses.
Return 'path+offset' when found, or None if address is not in any
mapped range.
