Bug Squashing Party on 2008/07/28-29

Communication via IRC

An IRC server is set up on and you need an IRC client to connect to it. IRC allows anyone to join when they become available without the need to invite them like we'd need to do if we used Google's or Skype's chat feature.

The client we have tested with the server is ChatZilla. Others may (probably do) work just as well. ChatZilla is available as an add-on for Firefox. Install it from Once you have installed ChatZilla just just follow this link irc:// or type it in firefox's address bar and you'll be connected: a ChatZilla window pops up. In the entry field on the bottom enter "/join bug" and you'll be on the "bug" channel with everyone else who has joined. When you want to leave just type "/leave".

In general, commands for the IRC server start with a "/". Few more important commands are:

  • /commands : lists all available commands
  • /help <command> : gives you help on a command.
  • /nick <new_nickname> : changes your nickname. Your default nickname is your login id. This command allows you to change it temporarily, and in the Preferences menu you can change it permanently.
  • /names : lists the nicknames of the people joined to the channel.

By default ChatZilla is in single-line entry mode, so whenever you hit enter, the line you just typed will be immediately sent to everyone on the channel. If you want to switch to multi-line mode (useful, e.e., entring code snippets) click on the small arrow right of the entry field. The direction of the arrow will change (clicking on that will switch back to single-line mode) and an "Enter" button is added there. Now you can just type away in the entry field and when you are ready for the others to see your work click on the "Enter" button.

Tickets to fix

These are tickets that look not too difficult to fix. Some are open for so long already that they might have been fixed in the meanwhile. A few are also invalid.

  • BuildTools ticket 64 - comitted my patch and rerun autotools
  • BuildTools ticket 66 - this should be fixed now, the dlamch.f file is now always compiled in debug mode
  • ...

(1) Studio does not like the way bonmin uses templates. Does not compile.

(2) Copy of Blis in Bcps/examples is out-of-date?  Studio complains that it's
    unable to match a template.  Does not compile.

(3) Misaligned data (double on 4-byte boundary). Kipp has details.

(4) Tests did not run automatically because the test in the top-level
    Makefile for Coin-All fails (no test/Makefile). When I tried to run the
    tests manually, the file Member/BB_packer.cpp was missing.

(5) test subdirectory not included in Coin-All, but DyLP was built and tested
    as part of Osi for all builds. Dylp's unit test is the Osi unit test, so
    that's as good as it gets.

(6) OsiCbc, OsiClp, OsiDylp, OsiGlpk, OsiSym, OsiVol.
    Studio builds also include OsiCpx (Cplex 9.1)
    Some solvers have issues but the unit test runs to completion.
