spivGood morning.00:53
pooliehi spivvo!01:02
poolienice to see pjkeating getting an outing again01:02
pooliejelmer, do you know off hand how many importer branches have succeeded?01:13
wallyworld_poolie: did you know "bzr xmlls" is broken on natty?01:35
pooliethat's from bzr-xmloutput?01:36
pooliei did not01:36
wallyworld_poolie: it's a python 2.7 incompatibility. i'll raise a bug01:37
wallyworld_  File "/usr/lib/python2.7/dist-packages/bzrlib/plugins/xmloutput/xml_errors.py", line 30, in __str__01:38
wallyworld_    _escape_cdata(str(e))01:38
wallyworld_TypeError: _escape_cdata() takes exactly 2 arguments (1 given)01:38
wallyworld_well i think it's python 2.7 related. haven't really looked into it01:38
wallyworld_it worked fine before i upgraded to natty01:39
jelmerpoolie: Sorry, was afk. I'm not sure how many successful imports we have.01:41
poolienp, i took a reasonable guess01:42
pooliehave a good night01:42
jelmerwallyworld_: I'm pretty sure that's been fixed in trunk, any chance you can give lp:bzr-xmloutput a try?01:42
pooliewallyworld, bug 73288101:42
ubot5Error: Launchpad bug 732881 could not be found01:42
pooliethought it rang a bell01:42

spivpoolie: Hey :)02:38
spivpoolie: ah, I guess freenode shenanigans or something kept you from seeing me earlier.02:38
pooliehi there02:39
poolieah i wondered if it was something like that02:39
poolieeither that or you'd abandoned 90s irc technology for tweeting02:39
spivHah.02:39
pooliehow are the failures?02:42
spivThe LP workaround has passed ec2 and so landed on lp:launchpad02:43
poolieok, and i guess will go live on the next downtime rollout?02:44
spivI guess so02:44
spivHmm02:45
spivI assume code changes on codehosting ssh aren't rolled out until there's downtime to restart the service02:46
spivBut because it's really split into the 'listens on ssh port' process and the 'bzr lp-serve' worker processes, in principle improvements to the latter could often be deployed without restarting the former.02:46
poolieyeah02:47
poolieok, and so now ... the twisted upstream fix?02:48
spivI guess when the ssh service can be brought down gracefully by being run behind haproxy there won't be as much incentive to try take advantage of that.02:48
spivs/brought down/upgraded/02:48
spivIs still waiting for a hopefully final review.02:48
spivAll the review points so far have been addressed.02:49
pooliegreat02:49
pooliei guess i will look into this possible whoami related selftest regression first02:51
pooliesince a lot of other outstanding stuff hangs off that02:51
pooliehow about you?02:52

pooliegood idea02:57
spivpoolie: hmm, hydrazine is now broken for me on maverick04:11
spivTypeError: login_with() got an unexpected keyword argument 'application_name'04:11
spivI do want to upgrade to natty quite soon, but perhaps not *right now* ;)04:12
poolie:/04:13
pooliei guess it needs some version-conditional code then04:14
pooliecould you have a go at it?04:14
spivI took a quick stab at backing out just that one revision to see the difference and got a surprisingly large conflict, so I just reverted to the version I was using before.04:16
poolieok i'll try when i can get unity going04:16
pooliespiv could you glance at https://code.edge.launchpad.net/~mbp/bzr/doc/+merge/5587205:20

fullermdNot that I know of.11:38
jelmerhrw: it's not planned; we should be able to get the new snapshot from Debian synced if there's a good reason to11:39
hrwjelmer: trying to get git-bzr-ng working again - it lists 0.10.0 as requirement11:42
jelmerhrw: natty has a 0.9 snapshot IIRC, I think it has the fixes required by git-bzr-ng11:43
hrwjelmer: bzr: ERROR: unknown command "fast-export"11:44
hrwhttp://paste.ubuntu.com/590170/ is whole output11:46
jelmerhrw: does "bzr plugins" list the fastimport plugin?11:47
hrwha! nice catch. http://paste.ubuntu.com/590175/ shows that it is installed but bzr does not know that11:48
=== psynaptic|away is now known as psynaptic
hrwbut why it happened? no idea11:52
vilahrw: python version mismatch ?11:54
hrwvila: fastimport landed in /usr/lib/pymodules/python2.7/bzrlib/plugins/ when all other plugins are in /usr/lib/python2.7/dist-packages/bzrlib/plugins directory11:55
hrwthis is under natty (which was upgraded from maverick in beginning of development cycle)11:56
vilahrw: 'bzr plugins -v' will tell you where plugins have been  found11:56
hrwvila: already used -v to find where normally they reside. only bzr-fastimport got into other place11:57
vilahrw: I'm not *that* familiar with packaging to say what the right directory is, but it's weird that two different ones are used (not counting link farms)11:57
jelmerI bet it's the switch to python-support that's related11:59
hrwjelmer: sure. but why bzr does not check python-support dirs too?12:00
vilahrw: could be a bug in packaging, you're using the daily ppa ? (Obviously no: bzr-fastimport 0.9.0+bzr311~ppa129~natty1  there)... where did your package come from ?12:00
jelmerhrw: bzr simply uses the standard python import mechanism12:01
vilaha, no, you're using stock natty12:01
hrwvila: plain natty package12:01
vilayup, rmadison told me12:02
hrwanyway - symlinked it to ~/.bazaar/plugins/fastimport for now12:02
jelmerhrw: it's definitely some sort of packaging issue, any chance you can file a bug?12:02
vilayou meant s/to/from/ ?12:02
hrwvila: ln -sf /usr/lib/pymodules/python2.7/bzrlib/plugins/fastimport/ ~/.bazaar/plugins/fastimport/12:03
vilabut yeah, easiest work-around if you don't want to put a branch there12:03
hrwjelmer: sure12:03
jelmervila: what's the problem with try/finally in tests?12:04
* vila nods ln -s will confuse me until my death, there is no way I will get it right now after getting it wrong for the past 30 years12:04
vilajelmer: error-prone, less clear generally12:04
vilajelmer: there are some exceptions but as a rule, avoiding them is generally better12:05
jelmervila: I understand less clear, but in what way is it error-prone?12:05
jelmerI don't have any objection to using self.addCleanup(), just curious.12:05
vilahmm, yeah, what did I mean...12:05
vilayou can define the try/finally scope wrongly12:06
jamjelmer: try/finally also tends to lead to terrible scopes when you have 3-4 of them12:07
vilaor more generally forget it, whereas using addCleanup *unless* you can't wait the end of the test to cleanup is generally safer12:07
jelmerah, fair enough12:07
vilajelmer: so it's kind of error-prone to *not* use addCleanup12:07
vilajelmer: which may be more precise than saying try/finally is error-prone12:08
vilajelmer: yeah, I think that's what I meant :D12:08
vilazomg, when did the ppa pages got the stop signs in 'Latest updates' ?12:09
vilafor ever but I never look at the page while failures where pending ?12:10
spivjelmer: the two basic problems with try-finally vs. addCleanup are12:10
hrwjelmer: bug 75239612:11
ubot5Launchpad bug 752396 in bzr-fastimport (Ubuntu) "bzr-fastimport is not listed in "bzr plugins" list" [Undecided,New] https://launchpad.net/bugs/75239612:11
spiv1) if the cleanup is distant from the initial action (i.e. many lines away) it's easier for skew between those to be missed, and12:11
jelmerhrw: thanks, marked confirmed12:11
spiv2) an error in a finally block will override a prior error12:12
hrwgit-bzr-ng now works in both directions - finally no need to touch bzr directly ;D12:12
spivSo you can get e.g. TooManyConcurrentRequests or some odd pack exception rather than the actual problem.12:12
spivAnd there's related things like if you have code like "if cond: foo.lock_read()" then you need to say "if cond: foo.unlock()" in your finally, so you're repeating yourself12:14
jelmerspiv: that makes sense, thanks12:14
spivBasically, default to using addCleanup everywhere it's conveniently available… and if it's not conveniently available, consider using it anyway ;)12:14
vilajelmer: and I don't remember a case where migrating from try/finally to addCleanup made the test harder to read or maintain12:15
vilajelmer: but a lot of cases where it fixed some nasty bugs12:15
jelmerjust to be clear, I'm not arguing for try/finally, I was only wondering why addCleanup is better.. I think I know now :)12:16
vilawell, may be no a lot, but some lock checks failures were fixed this way12:16

jelmerone of the nice things of splitting bzrlib.tests out is that it can actually depend on python-testtools properly17:21
maxbPerhaps "No module named testtools" was sufficiently informative to class as "reacting nicely" in my head :-)17:23
jelmerheh, fair enough17:23
maxbOK, so we could either patch cmd_selftest upstream to say something like "The testsuite is not part of this bzr installation", or we could patch it in the packaging branch to suggest 'apt-get install python-bzrlib-tests' similar to what the debian mercurial package does for this sort of thing17:25
