| micahg | nucc1: it means you don't have gnome-pkg-tools and cdbs installed | 15:14 |
| nucc1 | micahg, had cdbs, didn't have gnome-pkg-tools and dh-autoreconf . someone at ubuntu-devel told me. thanks | 15:15 |
| micahg | nucc1: ah, ok, you can use apt-file to tell you what package something is in | 15:16 |
| nucc1 | cool | 15:16 |
| nucc1 | if you're trying to patch an ubuntu package, is there a shorter way to get to test it? | 15:16 |
| nucc1 | currently, you have to build a .deb and install it | 15:16 |
| Amaranth | I don't see how it could get shorter, you have to actually compile the thing and test to make sure it works... | 15:18 |
| micahg | nucc1: no, that's the only way at least for a compiled program, for an interpreted program, you can copy the file on the system, but that's only a partial test | 15:19 |
| nucc1 | Amaranth, yes, compile, but skip the build a deb and install part. | 15:19 |
| nucc1 | micahg, thanks | 15:19 |
| Amaranth | nucc1: well if you run debuild binary it'll only do the full build once | 15:20 |
| Amaranth | nucc1: and further changes will only recompile the things you changed then make the package | 15:20 |
| Amaranth | once you think you've got it you should do a full regular build though | 15:20 |
| nucc1 | Amaranth, i was following the instructions here: https://wiki.ubuntu.com/Bugs/HowToFix | 15:21 |
| nucc1 | and that uses pbuilder-dist which seems to build the entire thing | 15:21 |
| Amaranth | Right, you'll want to do that once you've got a proper fix | 15:21 |
| nucc1 | so what command do i run to do a quick build? | 15:22 |
| Amaranth | debuild binary | 15:22 |
| Amaranth | it won't be quick the first time, you of course still have to build everything | 15:22 |
| nucc1 | ah, lol. my eyes saw "debbuild" | 15:22 |
| Amaranth | think of it like make but also building the package | 15:23 |
| nucc1 | yea, it seems to require me to install all the dependencies | 15:23 |
| Amaranth | of course | 15:23 |
| Amaranth | you need to be able to compile it :) | 15:23 |
| nucc1 | yes, pbuilder-dist seems to do that in some sort of way. anyway, if i actually install the dependencies, then i should be able to get away with the standard ./configure && make ? | 15:24 |
| Amaranth | nucc1: no, use debuild | 15:24 |
| Amaranth | pbuilder sets up a chroot and installs the dependencies there | 15:24 |
| Amaranth | but it installs them every time you run it, thus it takes quite a while | 15:25 |
| nucc1 | yea | 15:25 |
| nucc1 | running sudo apt-get build-dep now. | 15:25 |
| nucc1 | anyway, the issue i was tracking seems to be out of my league :p | 15:25 |
| nucc1 | a segfault in evolution | 15:25 |
| Amaranth | ah, do you have a stack trace? | 15:26 |
| nucc1 | i got some stuff out of gdb yes, https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/703488 | 15:26 |
| Amaranth | usually it's just a missing NULL check for forgetting to keep a reference to something | 15:26 |
| ubot2 | Launchpad bug 703488 in evolution (Ubuntu) "Evolution crashes if you drag and drop a file on the message list (affects: 1) (heat: 6)" [Undecided,New] | 15:26 |
| nucc1 | Amaranth, yes, but i couldn't find where to place the check :) | 15:26 |
| nucc1 | I tried valgrind, it was reaallly slow on my machine and i didn't quite understand what it was telling me afterwards | 15:27 |
| Amaranth | nucc1: well, it tells you where the crash was (line 873 of em-utils.c) | 15:27 |
| nucc1 | yes, that is not the source, cos i added a null check there but it still crashed | 15:28 |
| Amaranth | nucc1: in gdb run 'thread apply all bt full' when it crashes | 15:28 |
| nucc1 | ok, lemme try that now | 15:28 |
| Amaranth | that'll give you the entire detailed backtrace for every thread running | 15:28 |
| nucc1 | evolution is taking a while to quit... storing folder | 15:30 |
| nucc1 | Amaranth, http://paste.ubuntu.com/554749/ i suspect i need to install more dbg symbols | 15:35 |
| Amaranth | nucc1: that crash doesn't look anything like the first one | 15:35 |
| nucc1 | ah, seem to be many | 15:35 |
| Amaranth | nucc1: you did run it and wait for it to crash, right? | 15:36 |
| nucc1 | yeap. i've found it. let me paste it | 15:36 |
| nucc1 | Amaranth, http://paste.ubuntu.com/554750/ | 15:37 |
| Amaranth | nucc1: well, there you go, uris is 0x0 | 15:38 |
| Amaranth | Should uris be NULL at that point or is that your bug? | 15:38 |
| nucc1 | uris should not be null, because it get's set when a file is dropped onto the window. however, NULL is a valid value, but there is no null check | 15:40 |
| nucc1 | that sounds dense. | 15:40 |
| nucc1 | Amaranth, see the snippet, with my added null check: http://pastie.org/1466913 | 15:41 |
| nucc1 | (the ubuntu pastebin is not so convenient for repeated use) | 15:41 |
| Amaranth | nucc1: line 3 is your addition? | 15:42 |
| nucc1 | yes | 15:42 |
| Amaranth | odd, line 873 is actually in a different function... | 15:43 |
| nucc1 | line 873 is the first line of the loop | 15:44 |
| Amaranth | nucc1: oh, are you using maverick? | 15:46 |
| nucc1 | ah, yes :) | 15:46 |
| * Amaranth is looking at natty evolution | 15:46 | |
| nucc1 | lol | 15:46 |
| Amaranth | nucc1: in that case the first thing you should do is see if it still happens with natty's packages | 15:46 |
| nucc1 | that means a VM... | 15:46 |
| Amaranth | or just installing them on top of your maverick install | 15:47 |
| Amaranth | nucc1: but it's a waste of time trying to fix a bug that may already be fixed | 15:47 |
| nucc1 | that could pull in stuff that might make my machine unstable. | 15:47 |
| nucc1 | true, i just figured it was still helpful to fix it on a stable release | 15:48 |
| nucc1 | Amaranth, you could drag and drop a file onto evolution and see if it crashes :) | 15:50 |
| nucc1 | the message list, that is | 15:50 |
| Amaranth | nucc1: I don't even have it installed :) | 15:50 |
| nucc1 | lol | 15:50 |
| nucc1 | ok, lemme download the ISO. | 15:50 |
| Amaranth | why would you drag a file on to the message list anyway? | 15:51 |
| nucc1 | happened by mistake | 15:51 |
| nucc1 | then it felt embarrassing that the default mail client crashes when you drop a file on it. | 15:52 |
| nucc1 | so i figured, lemme have a go at it | 15:52 |
