apport emacs bugs should include failed byte-compilation logs

[era]

Binary package hint: emacsen-common

This is a bit of a feature request, but it would be nice to get this for Karmic.

Bugs such as bug #411939 should include a copy of the requested log file. There are hooks in apport for doing this, but I'm not altogether sure how the pieces should fit together.

> !! Please file a bug report against emacs-snapshot
> !! and attach the file /tmp/emacs-snapshot.SuWGoG

Basically, any line in the dpkg terminal log which matches '!! and attach the file /tmp/x?emacs' and where the file in /tmp still exists should be included, at least as a first cut.

Can emacsen-common install a hook which is used by all emacsen, or will each need to provide its own?

Is there other information which should be included in apport bugs? I'm thinking installed Emacs extensions would be good to have listed as well.

Maybe I'm pointing out the painfully obvious, but this is the problem I
am attempting to solve with this request. I'm not familiar enough with
apport to know precisely how to make it attach /tmp/emacs*.* files to
the bug report automatically, so I was kind of hoping somebody with the
prerequisite skills would be able to at least briefly instruct me on how
to approach this.

If this were a real .signature, it would suck less. Well, maybe not.

triaging this bug. I feel that we should implement this better sooner than later.

[Reinhard Tartler (siretart)]

the code that print outs these temporary files is implemented directly in the emacs22/emacs23/emacs-snapshot postinst scripts. All postinst scripts must be "fixed" seperately.

Documenation how to write apport scripts can be found here: https://wiki.ubuntu.com/Apport/DeveloperHowTo

However AFAIUI there is no direct way to invoke apport properly from a postinst script without causing apport to be triggered twice. Does someone know a package that does this properly?

[Reinhard Tartler (siretart)]

as discussed in https://lists.launchpad.net/ubuntu-elisp/msg00036.html, this is best implemented in apport.

This bug was fixed in the package apport - 1.11-0ubuntu3

---------------
apport (1.11-0ubuntu3) lucid; urgency=low

  * Attach emacs compilation logs in order to assist bug triaging.

From the bzr branch:

Although I don't have any experience with xemacs, I'm wondering if it shouldn't be included here just like the other emacsen, for completeness if nothing else.

[era (era)]

Oh, and by the by, that probably requires the regex a few lines down to be updated a bit as well.

Thanks for your work on this, it's much appreciated!

[Reinhard Tartler (siretart)]

yes, that seems to be a good idea. Do you have a patch or branch at hand?

Nope, I don't, but the change should be trivial -- just change emacs to x?emacs everywhere. This is based on the listing of Emacs package names in the Debian Emacs policy, as included in /usr/share/doc/emacsen-common (I have a slightly old version; this system is still on Jaunty).

As of Karmic, only xemacs21 seems to be availble.

Off the top of my head:

-if report['Package'] in ['emacs22', 'emacs23', 'emacs-snapshot']:
+if report['Package'] in ['emacs22', 'emacs23', 'emacs-snapshot', 'xemacs21']:
            # emacs add-on packages trigger byte compilation, which might fail
            # we are very interested in reading the compilation log to determine
            # where to reassign this report to
- regex = r'^!! Byte-compilation for emacs\S+ failed!'
+ regex = r'^!! Byte-compilation for x?emacs\S+ failed!'
            if 'DpkgTerminalLog' in report and re.search(regex, report['DpkgTerminalLog'], re.MULTILINE):
                for line in report['DpkgTerminalLog'].split('\n'):
                    m = re.search(r'^!! and attach the file (\S+)', line)

I've uploaded that change now, sorry for the delay

Did this ever make it to production? I have yet to see a bug report with an attached byte compilation log.

[era (era)]

Ping? I see the code in Lucid but it doesn't appear to be doing anything. Should the hook be moved so it doesn't require the package to be Emacs specifically?

[era (era)]

For the record, emacs23 and emacs-snapshot do not store the byte compilation logs in a temporary file. Only emacs22 users would see this, and of course, there aren't a lot of them any more. (Can't remember which category xemacs21 was but I guess it's also not very relevant.)
