| infinity | barry: Can you SRU bug #938869 to precise as well? | 00:03 |
|---|---|---|
| ubottu | Launchpad bug 938869 in lsb (Ubuntu Raring) "lsb_release crashed with SIGABRT in Py_FatalError()" [High,In progress] https://launchpad.net/bugs/938869 | 00:03 |
| infinity | barry: From my reading of it, it's just as buggy there, it's just that we haven't (yet) seen a a crazy upstream package that, say, sets a py3.2 PYTHONHOME and breaks python2.7. | 00:03 |
| infinity | barry: (Of course, the realisation that every other python script in /usr/(s)bin is wrong is a bit scary, but lsb_release does seem to be called an awful lot in these sorts of scenarios) | 00:04 |
| barry | infinity: indeed about the scary bit ;). let me just verify that i can break it in precise and i'll sru it there to if necessary | 00:09 |
| infinity | barry: http://paste.ubuntu.com/1301515/ | 00:12 |
| barry | infinity: cool | 00:13 |
| infinity | barry: Do I smell an ammendment to Debian Python Policy and a mass bug filing in the future? | 00:14 |
| barry | infinity: probably so. i will be out tomorrow giving my talk, but i plan on at least bringing it up on the d-p list asap | 00:14 |
| infinity | barry: I'm not sure if it's sheer luck that this hasn't broken more often, or just proof that most of the python stuff in /usr/bin is useless. :P | 00:15 |
| barry | :-D | 00:15 |
| infinity | I have always wondered why lsb_release isn't a shell script. | 00:15 |
| infinity | Other than language flavor-of-the-month-ism. | 00:16 |
| infinity | Which is probably the reason. | 00:16 |
| * barry licks python | 00:16 | |
| barry | er | 00:16 |
| * barry likes python | 00:16 | |
| infinity | *snicker* | 00:17 |
| infinity | I can take it or leave it, but I could frame it differently. I really like Perl, but I still think lsb_release should be a shell script. | 00:17 |
| infinity | Cause it does, well. Nothing. And hardly needs the massive memory footprint and load time to do all that nothing. | 00:17 |
| slangasek | infinity: why would you expect this to be common breakage? | 00:18 |
| slangasek | setting PYTHONHOME and then invoking system utilities seems crackful | 00:18 |
| slangasek | the only case I'm aware of that we've seen so far is with vmware | 00:18 |
| barry | slangasek: and what vmware is doing is crackful | 00:19 |
| slangasek | yep | 00:19 |
| infinity | slangasek: I'd expect it to be common if more of those system utilities were actually called by crackful third parties. Luckily, most of the crack they call is likely all binaries. | 00:19 |
| barry | slangasek: -s makes some sense too, but i bet few users are putting anything in their user site directory | 00:19 |
| infinity | slangasek: I didn't claim the crack should happen more often, just that I suspect it probably does happen more often, and those people just don't call python binaries in the midst of their crack. | 00:20 |
| barry | slangasek: i'd say: it's an important thing to do when writing system scripts, but we needn't freak out about it | 00:20 |
| slangasek | right, exactly | 00:20 |
| infinity | And yeah, I agree that it's not worth a crazy freak out. But a transition to -Es over time doesn't sound like the worst idea. | 00:20 |
| infinity | Anyhow, this all just came about from my "if we're fixing it in Q and R, we should fix it in P" thing, that's all. Since we have 4.5 more years of P, I'm sure VMWare will at some point start shipping a bundled python3 that breaks P the way their bundled python2 breaks Q. :P | 00:22 |
| infinity | I'm such an optimist. | 00:22 |
| barry | infinity: sru'd and uploaded | 00:26 |
| * barry -> eod | 00:26 | |
| infinity | barry: Thanks. | 00:30 |
| * infinity processes those and EODs himself. | 00:30 | |

| vibhav | Does anybody know how to setup a raring pbuilder chroot? | 02:43 |

| xnox | the bug is interesting, the unit test passes but upon clean up python interpreter itself segfaults after/during cleaning up floats. Maybe barry or doko can look into it ^^^^ | 11:31 |
| * xnox is rebuilding in debian at the moment to see if debian is affected as well or not. | 11:32 | |
| xnox | OdyX: in debian shiboken builds fine.... | 11:36 |
| OdyX | xnox: eh :) It looks like a ubuntu python bug to me | 11:53 |
| doko | xnox, hmm, mpi4py had someting similiar, was fixed in http://launchpadlibrarian.net/120852567/mpi4py_1.3%2Bhg20120611-1_1.3%2Bhg20120611-2.diff.gz | 11:53 |
| xnox | doko: I'd agree with you, but the unit test passes in shiboken case (no asserts about ref-counts) it's just python segfaults after the unit-test has passed and said so. | 11:59 |
| xnox | and it segfaults all pythons after passing the unit test in Ubuntu, but everything is ok in Debian. | 11:59 |

| alexbligh | If I am packaging an program which contains shared libraries, Lintian is warning me that "non-dev-pkg-with-shlib-symlink", which I'm guessing means the shared library symlinks should not exist in the package. I can remove them, but what is it that runs ldconfig on install? | 15:34 |
| cjwatson | Those are two unconnected questions ... | 15:35 |
| cjwatson | The point is that .so links should generally go in a -dev package, not in the runtime package, because the only thing that needs the .so links (as opposed to .so.N) is the linker (ld) when building other packages against this library, not the runtime linker (ld.so) | 15:36 |
| cjwatson | ldconfig calls are inserted into your package's maintainer scripts by dh_makeshlibs | 15:37 |
| cjwatson | Incidentally, you don't need to guess what lintian messages mean; you can use lintian-info. | 15:37 |
| alexbligh | cjwatson, ah. So if this is a not a -dev package I can simply delete all symlinks in /usr/lib in the dist directory that the makefile for the undebianised things builds? | 15:38 |
| cjwatson | The details of exactly how to arrange it for any given build system vary. | 15:38 |
| cjwatson | Generally you install it into debian/tmp/ rather than debian/your-package-name/ (which dh_auto_install will do by default if you have multiple binary packages, as you should in this case) and then have dh_install pick the right files to put in each binary package. | 15:39 |
| alexbligh | actually, per the lintian-info thing, I think this is harmless | 15:40 |
| alexbligh | yes, it's actually a copy of the dist directory. | 15:40 |
| cjwatson | It is not the worst lintian error you could have, but it *is* generally wrong and should be fixed. | 15:40 |
| cjwatson | People expect shared library packages to be done in broadly the same way as all other shared library packages. | 15:40 |
| alexbligh | cjwatson, there are are LOT of things wrong with this package - I'm sort of looking for a quick and dirty hack and repackaging xen. | 15:41 |
| cjwatson | The exception is if it's a private library that isn't intended to be exposed outside this program, in which case you should put it in a private subdirectory of /usr/lib, not in /usr/lib itself. | 15:41 |
| cjwatson | Yeah, I'm not going to advise you on how to do things wrong, though :-) | 15:41 |
| alexbligh | cjwatson, I appreciate that :-) | 15:42 |
| alexbligh | dh_shlibdeps seems to complain if I start deleting symlinks. | 15:43 |
| alexbligh | so I'll guess I'll leave it in horrible hacked state for now. | 15:43 |
| cjwatson | Eh, the point isn't to delete symlinks | 15:46 |
| cjwatson | The point is to put them in the right binary packages | 15:46 |
| alexbligh | cjwatson, sure; what I'm saying is that if it's permissible for a 'small package', it isn't the worst sin in the world to do it on a larger package. Given the other horrors I have to contend with, I'm putting this in the 'mostly harmless' box :-) | 15:50 |
| alexbligh | (permissible per the lintian-info notes) | 15:50 |
| cjwatson | Yeah, I read those notes after I said that and I think they're far too lenienet. | 15:51 |
| cjwatson | Or misphrased. | 15:51 |
| cjwatson | I have a 50KB library package which does it right. Can't get much smaller. | 15:51 |
| alexbligh | after all, xen4.2 is a really small package (cough cough) | 15:52 |

| ubottu | Python 2.6 through 3.2 creates ~/.pypirc with world-readable permissions before changing them after data has been written, which introduces a race condition that allows local users to obtain a username and password by reading this file.

| jdstrand | barry: it isn't a big deal, but it would be nice to get it applied upstream | 18:14 |
| xnox | doko: last time this was brought up by wookey ( i think ) the "meta-packages" to select the default arch:any packages should also be arch:any. | 18:15 |
| xnox | Otherwise multi-arch will not be able to do it's multiarch magic. | 18:15 |
| xnox | cause it will not know how to do an M-A jump arch:all -> arch:any dep. | 18:16 |

| xnox | well all of them to be honest. | 18:17 |
| doko | haven't to be all, I think. why the packages with the binary symlinks? | 18:17 |
| xnox | because otherwise I will not be able to do build-dep python3:any | 18:19 |
| doko | hmm, maybe | 18:21 |
| doko | ohh I hate this multiarch stuff now | 18:21 |
| doko | xnox, should fixed packages be uploaded to the ppa, and then copied to the distro? | 18:22 |
| xnox | doko: I am not sure =) but for one package I uploaded into both. | 18:22 |
| xnox | doko: plus this round of uploads has slightly wrong changelog entries (i didn't pass --nomultimaint to dch, while my ~/.devscripts was setting it) | 18:23 |
| xnox | so currently there are [ Joe Bloggs ] * Rebuild for python3.3 -- Dmitrijs Ledkovs | 18:23 |
| xnox | entries =/ | 18:23 |
| xnox | doko: are you fixing up python3-defaults? | 18:24 |
| doko | well, fixing will be splitting the packages ... | 18:24 |
| * xnox haven't worked out how to bump the version in debian/changelog yet still have packages matching in version number with the real pythonX.Y default version number. | 18:24 | |
| xnox | doko: create .pc symlink at postinst? =))))) | 18:25 |
| * xnox hopes slangasek doesn't notice this suggestion. | 18:25 | |
| doko | well, as a quick fix I consider adding this link into the libpython3.3-dev package | 18:26 |
| doko | and removing it from the python-defaults package | 18:26 |
| xnox | doko: but how would libpython3.3-dev know it's the default? | 18:27 |
| slangasek | good way to avoid me noticing | 18:27 |
| slangasek | since I have /hilight and /ignore confused | 18:27 |
| doko | xnox, because it will be in the ppa | 18:27 |
| xnox | doko: ok. what about the real fix. | 18:28 |
| slangasek | what .pc files are you talking about? | 18:28 |
| doko | later, not before uds | 18:28 |
| slangasek | why would a .pc file not be shipped in the per-arch directory? | 18:28 |
| xnox | slangasek: python3-dev ships symlink python3.pc -> python3.X.pc | 18:28 |
| slangasek | ok, so if it wasn't already clear, python3-dev needs to be Arch: any | 18:29 |
| xnox | slangasek: currenlty python3-dev is arch:all package, but since 3.3 is multiarched, the meta-packages should be "multi-arched" as well, which for really means arch:all -> arch:any | 18:29 |
| slangasek | I have filed bugs in the past about this - python(3)-defaults need to be made arch: any | 18:29 |
| slangasek | doko: ^^ you understand this, right? We need to be able to specify the needed architecture of python3-dev for cross-building | 18:30 |
| xnox | slangasek: all packages it builds? I looks like -doc can stay as arch:all, not sure about idle3 (it has python3 = ${binary:version} so probably arch:all as well) | 18:30 |
| doko | slangasek, I do understand that it's not needed to make 3.3 the default. that's the priority for now | 18:31 |
| slangasek | xnox: yes, sorry, was being overly brief there | 18:31 |
| xnox | doko: the boost-defaults builds all packages as arch:any | 18:31 |
| slangasek | doko: true | 18:31 |
| xnox | ack. | 18:31 |
| slangasek | xnox: AFAIK the only one we care about is -dev | 18:31 |
| slangasek | doko: it's not the immediate priority, but it does need to be solved this cycle; I filed a bug about this about a year ago, and it blocks cross-bootstrapping | 18:32 |
| doko | so, I'll prepare an python3.3 upload for the ppa | 18:32 |
| xnox | slangasek: I thought we equally care a lot about "Build-Dep: python3:any" | 18:32 |
| xnox | doko: thanks. | 18:32 |
| slangasek | xnox: you only build-depend on python3 (instead of python3-dev) when you aren't building C extensions; therefore you don't care about the architecture of python3 being installed; so it can be Arch: all and rely on arch-all build-deps being implicitly Multi-Arch: foreign | 18:33 |
| doko | slangasek, there will be so many python cross build failures ... none of the various python build systems supports cross building | 18:33 |
| slangasek | doko: that's beside the point. Not having Arch: any python3-dev is *blocking* fixing those things. | 18:34 |
| doko | slangasek, you didn't, at least not for python3-defaults | 18:36 |
| slangasek | doko: possibly the bug was only filed against python-defaults. I can open a new task :) | 18:36 |
| * xnox slangasek's bugs outlive python2 | 18:37 | |
| doko | slangasek, better file a new one, your memory seems to be corrupted ;-) | 18:39 |
| slangasek | doko: bug #934593, which you closed and didn't reopen after you reverted the change! :) | 18:39 |
| ubottu | Launchpad bug 934593 in python-defaults (Ubuntu Precise) "python-all-dev, python-dev must be Arch: any for multiarch" [Medium,Fix released] https://launchpad.net/bugs/934593 | 18:39 |
| slangasek | (bug reopened) | 18:40 |
| doko | ahh, that one | 18:41 |
| xnox | So to fix the bug correctly: python3-dev should be arch:any package with symlink /usr/lib/$(arch)/pkgconfig/python3.pc -> python-3.X.pc | 18:43 |
| slangasek | yes | 18:43 |
| * xnox off to have dinner and will poke python3-defaults after that. | 18:43 | |
| === gallth is now known as tgall_foo | ||
| doko | xnox, how do you track the packages which you fix for the test rebuild? | 19:22 |
| doko | http://people.canonical.com/~xnox/py3.2/python3.2.html doesn't show any progress | 19:23 |
| doko | slangasek, xnox: the proper fix is to split out libpython3-{stdlib,dev,dbg} packages *and* make all of these arch any | 19:25 |
| slangasek | doko: what's the purpose of python3-dev, that would make it different from libpython3-dev/ | 19:26 |
| === morphis is now known as morphis|away | ||
| doko | slangasek, having the python3.3-config binary | 19:28 |
| slangasek | doko: and is it really useful to split the python3-dev package just for python3.3-config? | 19:29 |
| slangasek | it seems obvious to me that making python3-dev Arch: any is much simpler | 19:29 |
| doko | probably simpler, but how do you install a host interpreter, plus a target python-dev? | 19:30 |
| doko | most python build systems do use python as implementation for the build system | 19:31 |
| slangasek | python3-dev Arch: any Depends: python3.3-dev Arch: any Depends python3.3:any, with python3.3 as Multi-Arch: allowed? (Or Depends python3.3 with python3.3 as Multi-Arch: foreign, whichever is correct) | 19:33 |
| doko | why should it be allowed, and not same? | 19:37 |
| slangasek | assuming you mean foreign rather than same (since same is definitely wrong for an interpreter package): "allowed" would be correct if it contains libraries as well as the interpreter, otherwise "foreign" | 19:38 |
| doko | well, libpython3.3-dev is m-a same, as libpython3-dev would be too | 19:39 |
| slangasek | if libpython3.3 is M-A: same, and all the library bits are in libpython3.3, then python3.3 can probably be M-A: foreign | 19:39 |
| doko | right, libpython3-{stdlib,dev,dbg} would be m-a same, and python3{,dev,-dbg} would be m-a foreign | 19:43 |
| === cpg|away is now known as cpg | ||
| slangasek | doko: er, except then you're changing the policy for python build-dependencies | 19:44 |
| doko | but then how do I build not using the "target" interpreter? | 19:45 |
| slangasek | doko: right now, packages that build extensions build-depend on python3-dev. Splitting libpython3-dev out of python3-dev, and making python3-dev M-A: foreign, means packages would have to build-depend on libpython3-dev to be cross-buildable | 19:45 |
| slangasek | doko: apt will prefer to install the host version of any package that's marked Multi-Arch: foreign | 19:46 |
| doko | yes, this was my intention | 19:46 |
| slangasek | oh, I think I see the issue now | 19:46 |
| slangasek | /usr/bin/python3-config is not the same on all architectures, right? | 19:47 |
| slangasek | so it can't be in a M-A: same package | 19:47 |
| doko | yes | 19:47 |
| slangasek | ok | 19:47 |
| doko | currently it's meaningless because it's written in python, but it will be replaced by a shell script again | 19:48 |
| slangasek | so actually, I'm not sure it matters to have python3-dev as M-A: same... if it's M-A: none, it should still work | 19:48 |
| slangasek | then when cross-building, Build-Depends: python3-dev gets you the target arch version of python3-dev and the host-arch version of python3 | 19:48 |
| doko | and python3.3-dev depends on python3.3, with a different binary too | 19:48 |
| slangasek | you can't install more than one copy of python3-dev side-by-side, but for a first pass I don't think that's required | 19:49 |
| doko | ok, then let's delay the split of the python3-defaults packages for now | 19:49 |
| slangasek | "python3.3-dev depends on python3.3" but that's ok, isn't it? You should be able to use python3.3-dev:target + python3.3:host | 19:49 |
| doko | no | 19:50 |
| slangasek | why not? | 19:50 |
| doko | I can't see how this would be right | 19:50 |
| doko | if the build uses information from the sys or sysconfig modules, then these will come from the host, not the target | 19:51 |
| slangasek | if I'm not mistaken, it's right because python3.3 is *just* the interpreter, and python3.3-dev depends on the interpreter (which is Multi-Arch: foreign) + the lib (which is Multi-Arch: same) | 19:51 |
| slangasek | ok | 19:51 |
| slangasek | but that's a problem with the build system not being cross-build-safe | 19:51 |
| slangasek | I don't think there's any rearrangement of the interpreter packages that we can do to fix that | 19:52 |
| slangasek | installing the target-arch python3.3 doesn't solve the problem for a true cross-compile situation where you don't have qemu | 19:52 |
| slangasek | (such as, to pick a random example, aarch64) | 19:52 |
| doko | yes, known | 19:52 |
| slangasek | So I think python3.3-dev:target + libpython3.3:target + python3.3:host is still correct, and we just have to defer the fact that many build systems aren't cross-compile safe | 19:53 |
| doko | the trick for distutils I am using is to set an env var to use the host python with the target standard library | 19:54 |
| slangasek | but in the base system, there are a lot of *non*-python build systems being used which are cross-build-safe, they just need the right libpython available | 19:54 |
| doko | which works ok, as long as I'm only relying on sysconfig, not on the builtin sys module | 19:54 |
| slangasek | right | 19:54 |
| doko | indeed, and my idea was to have these packages now build-depend on libpython3-dev | 19:55 |
| slangasek | I still think it's better to keep everything build-depending on python3-dev; that way it doesn't require changing python policy or changing build-dependencies, and that change doesn't help cross-compile without qemu anyway so I think we should take our time to look for a better solution for those | 19:58 |
| ScottK | Help. | 20:02 |
| ScottK | In debian/rules for python-qt4, I have: configure: $(PYTHONS:%=pyqtconfig-%) $(PYTHONS:%=build-%/configure-stamp) $(PYTHONS:%=dbg-build-%/configure-stamp) | 20:02 |
| ScottK | I've added the $(PYTHONS:%=pyqtconfig-%) rule. | 20:03 |
| ScottK | If I run make -f debian/rules configure, then the pyqtconfig rule runs. | 20:03 |
| ScottK | But when I build the package, it does not (even though the build/dbg-build rules do) | 20:04 |
| ScottK | Any suggestions? | 20:04 |
| doko | slangasek, well, that would be brainstorming session for uds. I don't think that it will require a change to the python policy, as everything still builds, and python policy doesn't touch multiarch. and the b-d change ... how many packages are cross-buildable out of the box anyway | 20:04 |
| slangasek | ScottK: are you cleaning in between? | 20:04 |
| slangasek | doko: python policy says what build-dependencies are supposed to be | 20:04 |
| ScottK | No. | 20:04 |
| slangasek | ScottK: is pyqtconfig-$ver a real file? | 20:04 |
| slangasek | (pointer to source?) | 20:04 |
| ScottK | No. | 20:04 |
| ScottK | Let me publish this somewhere. | 20:05 |
| doko | slangasek, so yes, keep it unchanged, change it where it's needed for m-a | 20:06 |
| slangasek | doko: ok. in the meantime, will we still get Arch: any python3-dev? | 20:06 |
| slangasek | because that's still a blocker | 20:07 |
| doko | yeah, for the first milestone | 20:07 |
| slangasek | great, thanks :) | 20:07 |

| doko | ScottK, sip4 builds did finish, didn't see the python-qt4 upload ;-P | 21:15 |
| ScottK | Not quite there yet. | 21:16 |
| slangasek | ScottK: well, one thing is that you define a target for pyqtconfig-3.% but are patterning over $(PYTHONS) which includes python2 | 21:25 |
| slangasek | oh, but you have an explicit pyqtconfg-2.7 below | 21:26 |
| ScottK | Yes. | 21:26 |
| slangasek | so I suppose that should work | 21:26 |
| ScottK | Running configure directly failed without that. | 21:26 |
| ScottK | Switching to like I had it in sip4 doesn't help either. | 21:27 |
| ScottK | configure: $(PYTHONS:%=build-%/configure-stamp) $(PYTHONS:%=dbg-build-%/configure-stamp) | 21:27 |
| ScottK | build-%/configure-stamp: $(PYTHON3S:%=sipconfig-%) | 21:27 |
| slangasek | +install-arch-3.%: pyqtconfig-% | 21:28 |
| slangasek | that seems wrong? | 21:28 |
| slangasek | (but is probably not relevant) | 21:28 |
| slangasek | ScottK: oh; when I asked if these were real files you said they weren't | 21:29 |
| slangasek | ScottK: but you're clearly touching them | 21:30 |

| slangasek | ok | 21:30 |
| ScottK | The problem is they never get touched at all, so I know the rule never ran. | 21:30 |

| slangasek | ScottK: ah. Nothing actually depends on your configure rule. | 21:32 |
| ScottK | Hmmm. | 21:32 |
| ScottK | That would do it. | 21:32 |
| slangasek | the configure target depends on the configure-stamp targets; it should normally be the other way around... | 21:33 |
| slangasek | er, no | 21:33 |
| slangasek | that part is right - but then things should depend on configure instead of directly on the stamps | 21:33 |
| slangasek | probably simplest to make the build-arch target depend on configure | 21:34 |
