[0:05] * shashank (~shashank@c-98-245-87-8.hsd1.co.comcast.net) has joined #jython
[1:16] * wmeissner (~wmeissner@121.91.44.146) has joined #jython
[1:17] <wmeissner> pjenvey: when I try and clone the jython-test9 repo, it stalls when trying to update to the default branch
[1:18] <wmeissner> pjenvey: same thing after I kill that, and run 'hg up default'
[1:19] <pjenvey> wmeissner - you might need a later version of hg for the svn repos support
[1:19] <pjenvey> what version are you using
[1:20] <wmeissner> 1.8.2
[1:20] <pjenvey> hrmm
[1:20] <pjenvey> how long did you wait for it? it'll do a subversion checkout of CPythonLib, but it doesn't give you any output while it's doing it
[1:21] <wmeissner> no output, and its not pulling anything off the net either
[1:21] <wmeissner> and I waited about 30 minutes
[1:21] <pjenvey> blah
[1:21] <pjenvey> can you try it again with clone -vvv -debug
[1:21] <pjenvey> er, -vvv --debug
[1:22] <wmeissner> trying that with hg -vvv --debug up default (so I don't have to retrive the entire repo again)
[1:22] <wmeissner> subrepo merge 000000000000+ e7cbc21f9ac3 000000000000
[1:22] <wmeissner> subrepo CPythonLib: remote added, get https://svn.python.org/projects/python/branches/release26-maint/Lib/:88766:svn
[1:23] <pjenvey> i couldn't reproduce it just now, so it's not like svn.python.org is down
[1:25] <jimbaker> shashank, i was thinking more about the problem of mapping global names against indy
[1:25] <wmeissner> its transmitting/receiving traffic from there, but its _really_ slow
[1:26] <jimbaker> so ast analysis (see the scope compiler) will always tell us accurately whether a name is used globally. we will not see usage through globals(), but we will assume this is always a slow path anyway
[1:30] <shashank> jimbaker: ok yes, I don't think we need to make the globals() access fast, we should just make the most obvious case fast first..
[1:30] <jimbaker> so we generate setters/getters for all global names (good discussion on the relevant limits here - http://stackoverflow.com/questions/4342072/what-is-the-maximum-number-of-methods-a-java-class-can-have, suffice to say, it's a tuning decision on how many such names we would support, eg we would never expect module level scripts to hot anyway)
[1:30] <jimbaker> one interesting thing i think we can distinguish is a "namesite" (newly named!) from a callsite
[1:32] <shashank> NameSite is a good idea, it might help us in the future to have such distinction
[1:32] <jimbaker> if we can distinguish callsites from namesites, we should be able to have a cheap guard for the callsites where we expect low volatility
[1:36] <pjenvey> wmeissner - is a plain svn checkout from there the same?
[1:37] <jimbaker> pjenvey, shashank is currently following jython trunk with http://gradual.colorado.edu for his work on jython performance - of course everyone will want to be in the loop regardless when we cut over to hg
[1:37] <wmeissner> pjenvey: nope, svn co https://svn.python.org/projects/python/branches/release26-maint/Lib python2.6-Lib works fine
[1:37] <wmeissner> but it did complain about the certificate being invalid
[1:38] <wmeissner> I wonder if thats why hg is stalling?
[1:40] <pjenvey> I don't see why
[1:40] <pjenvey> it just forks off a svn checkout command
[1:41] <pjenvey> what version of python are you using?
[1:41] <wmeissner> 2.6
[1:42] <wmeissner> if its just executing svn, and that svn is waiting for input to allow the user to accept the certificate, that could explain the stall
[1:43] <pjenvey> ah, yes
[1:45] <pjenvey> so IIRC you should get an option when you do the checkout to accept the cert permanently
[1:45] <pjenvey> so if you did that during the manual checkout, the next time you do another checkout you shouldn't get the prompt about it
[1:46] <wmeissner> did that, but asks me again the next time
[1:46] <wmeissner> evidently, its not storing them permanently
[1:46] <pjenvey> puts them in ~/.subversion/auth
[1:47] <wmeissner> hmmm
[1:47] <wmeissner> yes, permissions problem
[1:51] <wmeissner> pjenvey: blowing away ~/.subversion and permanently accepting that cert worked
[1:51] * jimbaker (~jbaker@c-24-8-39-78.hsd1.co.comcast.net) Quit (Ping timeout: 246 seconds)
[1:51] <wmeissner> the joys of executing interactive programs from other programs
[1:52] <pjenvey> +the joys of using somewhat new hg features
[1:52] <wmeissner> yeh
[1:52] <wmeissner> still, at least it makes supporting svn externals *possible*
