            Bug ID: 18890
           Summary: libabigail hangs while processing DWARF
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: woodard at redhat dot com
                CC: libabigail at sourceware dot org
  Target Milestone: ---

There are many cases where abidw and abidiff hang processing DWARF. I have let
this run  as long as 85 minutes. 

This is with the latest abi-rework branch of libabigail which I got from Dodji.

--- Comment #4 from Ben Woodard <woodard at redhat dot com> ---
libgcj did finally complete the ABI abidiff run but it took several hours. So
this particular case may be more of an algorithmic optimization problem than a
bug.

Woo hoo it does ultimately finish with no errors and so the problem appears to
be just one of performance.

--- Comment #9 from Ben Woodard <woodard at redhat dot com> ---
Dodji maybe you can grab a machine with more memory to track this one down or
just add a big swap file. It appears to need about 8GB of RAM for this to run.
It has been using 8GB for more than an hour now and it hasn't seemed to budge. 

  6599 ben       20   0 8337m 8.0g 148m R 99.9  6.4 121:51.45 abidw       

As you can see it has been running for more than 2 hours now on a fast CPU a
Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz and so I think that there is a problem
here.

Hey Ben,

It looks like the binary wasn't attached finally as I cannot see it in the
attachments to this problem report.

Thank you for taking time to file this report, though.  I am now eager to get
my hands on those binaries to see how I can address the issue.

Oh, also, I have just merged the branch abixml-rework branch back into the
master branch; so master is where I'll try to reproduce the hang now.

Thanks!

--- Comment #3 from Ben Woodard <woodard at redhat dot com> ---
I cannot attach the ELF file that seems to demonstrate at least an excessively
long run time if not an infinite loop. I let it run for at least 23min before I
aborted it. However it can be downloaded from:
http://ssh.bencoyote.net/~ben/libgcj.so.bz2

--- Comment #1 from Ben Woodard <woodard at redhat dot com> ---
There are multiple binaries that trigger this. The attached file is just one.
When that one is fixed, I will retest to see if it is one problem or multiple
problems.

"infinite running" issues to see where the program is "stuck"

With the current master tree, at commit
https://sourceware.org/git/gitweb.cgi?p=libabigail.git;a=commit;h=75515395e1609000df42cf7ebfedb943ed42b547
abidw --abidiff now completes for me in 2 minutes and a half on the binary
libdyninstAPI.so.8.1.2.

I don't enough memory to test on the binary at
http://ssh.bencoyote.net/~ben/rewritersample.bz2.

Does that one pass for you now, with the current master?

librose seems to cause libabigail to hang.

http://ssh.bencoyote.net/~ben/rewritersample.bz2 seems to be a good
pathological test case.

So it has been running all night. This may be about as close to an infinite
loop as I can come up with.

I don't think that this is a problem anymore.
