Hello,
I've put together some basic implementation of ABRT support for Ruby. It
means that whenever your application/library fails in Ruby code (note
that this does not catch segfaults), it will be easy to your users to
report such problem into Bugzilla.
Source code: https://github.com/voxik/abrt-ruby
Gem: gem install abrt
ATM, there are several ways how to test the gem:
1) "require 'abrt'" in your code, as soon as possible, but later then
rubygems if you are using Ruby 1.8.
2) If you are already using Ruby 1.9, you can add "RUBYOPT='-rabrt'"
into your environment. This assures that every time Ruby is started, the
abrt gem is activated. Unfortunately, this doesn't work with Ruby 1.8,
since RubyGems are not loaded by default and "RUBYOPT='-rubygems
-rabrt'" does not work for some reason :/
Please note that ABRT reports errors just for Ruby libraries managed by
RPM. If something appears to not work as expected, it is good to observe
/var/log/messages for more details.
In the future, I'd love to see this integrated into Ruby (probably in
F18?). I already asked upstream about possible integration [1], but if
went without response, so it seems that I will have to come with some
proposal.
I'd love to here your comments and of course your patches :)
Thank you
Vit

Hello,
I have a question. Can we detect abrt enableness on runtime? I mean, I want to integrate
it to upstream. Ruby already has
similar support code for Mac. but I also want to fallback original behavior when a user
disable abrt service.

Hello Motohiro,

Hello,
I have a question. Can we detect abrt enableness on runtime?
I am not sure what is the best way how to detect ABRT enableness, but I
can clarify it with upstream. Actually such checking is not required I
would say, because:
1) If ABRT is not enabled, the gem cannot send the report via socket.
Only record into /var/log/messages is made.
2) I would like to see Ruby in Fedora automatically to try to require
abrt.rb and fail silently if the gem is not installed.
I mean, I want to integrate it to upstream. Ruby already has
similar support code for Mac.
Could you please elaborate what Mac support Ruby already has?
but I also want to fallback original behavior when a user disable
abrt
service.
The original behavior is always preserved (assuming that there is no bug
in the ABRT gem :)), i.e. the exception is written to terminal for
example. The report to ABRT is just extension.
With regards to SEGV, I believe that they are caught by ABRT anyway,
since Ruby itself is C, so they should be handled by ABRT C hook. Or are
you aware of some specific example which does not work that way?

Hmm.. this is not an item I wanted. when abrt is disabled, ruby shouldn't
run any additional code. any new code path might make application
deadlock. for clarify, the worst scenario is, ruby or ruby extention
made
memory corruption and libc internal function made SEGV and then libc
lock (libc internal mutex) was not released. any libc call may makes
deadlock. and if ruby don't exit, abrt can't record correct
information and
more importantly, crash watching daemon can't know ruby stop to
working and then fail to restart it.

Ruby didn't need any additional code for Mac. Its abrt like crash logger
automatically save a crash information. we only remove redundunt code.

Hmm.. this is not an item I wanted. when abrt is disabled, ruby shouldn't
run any additional code.
Hmm, there might be some additional code on startup checking if ABRT is
enabled and install the at_exit handler only if it is. However there are
two issues to consider:
1) There will be probably some slowdown to Ruby startup time, which may
penalize especially short scripts, but this might be unnoticeable.
2) What if the Ruby process is some long running service and ABRT is
started/installed later? But this looks a bit silly :)
any new code path might make application
deadlock.
Yes, that is true that this handler might get things worse, but it is
aimed to handle problems in your Ruby code, such as if you change some
functionality, but not adjust the rest of the application. So it is not
designed to check some errors in C code or extensions. However I really
should check, if for example SEGV in nokogiri is caught by ABRT.
for clarify, the worst scenario is, ruby or ruby extention
made
memory corruption and libc internal function made SEGV and then libc
lock (libc internal mutex) was not released. any libc call may makes
deadlock. and if ruby don't exit, abrt can't record correct
information and
more importantly, crash watching daemon can't know ruby stop to
working and then fail to restart it.
Hm, this is probably far beyond ABRT capabilities and design. Do you
believe that such problem is somehow detectable?

Ruby didn't need any additional code for Mac. Its abrt like crash logger
automatically save a crash information. we only remove redundunt code.
What I need to get this working is some thing like automatic inclusion
of os_prelude.rb during build time if that is available in build
directory, or alternatively some configuration option to achieve the
same, i.e. to require some .rb file which is somewhere available and
treat it as a prelude file. Of course I can patch the Ruby build to
include some os_prelude.rb, but I'd like to see this supported by upstream.

Oops. This seems wrong idea. When SEGV occur, ruby code can't work. we need simple C
extension, maybe. At least, you want to merge

Hi,
Updated ABRT gem version 0.0.2 is available at RubyGems.org if you like
to test it. I'd love to hear some feedback.
There were done following changes:
* Improved code base
* Better handling of some edge cases, such as call to Kernel#exit or
Ctrl+C event
* Test suite added
* Improved documentation
I also prepared RPM for Fedora. Review is available at
https://bugzilla.redhat.com/show_bug.cgi?id=838568

You are right, you can change the $PROGRAM_NAME. I'll make several
points here
* Is there some more reliable way how to detect the script name?
* What is the use case and how widely is this practice used? Can we
ignore this case? Python handler ignores it if I am not mistaken (but we
should be better of course ;)
* ABRT ignores such failure and it just logs something like "Executable
'foo.rb' doesn't belong to any package" into /var/log/messages.

If the Ruby documentation is to be believed you could use
Kernel#caller to get a stack trace which apparently has a set format
including the file name. It is of course swapping a user modifiable
value for something slightly more fragile (it could potentially change
in some future version). Perhaps use the current way and fall back to
Kernel#caller if $0 doesn't resolve to a real file (which would
indicate it has been modified.
None of this of course covers scenarios where user/other code is
loaded from within another program (think rake, thor, etc) but in the
case of an exception, Exception#backtrace is the same format as
Kernel#caller.

John, thank you. Use of the Exception#backtrace is nice idea! Have to
take a look into.
It might be even possible to extract the "latest gem" in the backtrace
and assign the bug to it, but I am not sure if that is good idea, since
the error might be in the gem as well as in its caller. In that case, I
would expect that the library consumer/application author has "more"
knowledge about the library then the library author about the
consumer/application. Thoughts?

Yeah i think you are right there. The entry point is the only
guaranteed thing. The more you narrow things down from there the more
work is needed to avoid getting things wrong so it really depends on
how much effort you want to put into it.
Certainly if i was maintaining a ruby program i would not mind
receiving bugs that are in the end caused by a library used by my
program. I would easily be able to forward it on plus if i have had a
bug then i can watch for the fix etc. Bonus points though if the
report could include a complete list of loaded gems/packages (to help
in ruling out monkey patching issues and the like) and the list of
gems/packages in the call stack at the time of the error (would make
it much easier to see where the problems _could_ be).

Right. I will keep it simple for now, report it to the entry point
application. Thinking about gems would definitely add more fragility
than anything else.
Bonus points though if the
report could include a complete list of loaded gems/packages (to help
in ruling out monkey patching issues and the like) and the list of
gems/packages in the call stack at the time of the error (would make
it much easier to see where the problems _could_ be).
This could be done. The python handler for example adds values of local
variables as a bonus. This might be also very valuable information. Will
try to keep that idea in mind, if I'll get bored ;)

Local variables would be great although at this moment in time i can't
think how to get at them by the time an exception has been caught. If
you are interested in and want any help with my own suggestions i
would be more than happy to fork and submit a potential implementation
upstream when i get some free time next week :-)
