[Bug 1036283] Re: callgrind_control cannot connect because of different executable name

[Sjors Gielen]

Thanks for releasing the patch Steve. By the way, I think you've quoted
the wrong patch in this bug (fix-buffer-overflows.patch instead of
05_fix-callgrind_control.patch) but the right patch is in the version
anyway. As soon as it's in -proposed I'll test it and give you a quick
reply.

Title:
  callgrind_control cannot connect because of different executable name

Status in “valgrind” package in Ubuntu:
  Fix Released
Status in “valgrind” source package in Precise:
  Fix Committed

Bug description:
  [Impact]
  When starting a Callgrind session using "valgrind", the actual executable name is "valgrind.bin". However, when callgrind_control searches for processes, its Perl regexp does not allow for this possibility. See callgrind_control line 32:
  Additionally the code contains several buffer overflows that can break depending on compiler optimizations.

  [TESTCASE]
    $ valgrind --tool=callgrind sleep 100 &
    $ callgrind_control -b
    No active callgrind runs detected.
  After making the change:
    $ valgrind --tool
    $ callgrind_control -b
    PID 23522: sleep 100

  [Regression Potential]
  the program currently doesn't work properly so there is little risk of things getting worse.
  The overflow fixes are applied upstream since several month and the process name fix is also in debian wheezy.
