[0:06] <Tv> hey at least we're talking about platforms that are beefy enough to compile their own code
[0:06] <Tv> arm was.. "interesting"
[0:07] <Tv> my favorite scar from arm-nommu was that non-aligned 4-byte reads saw abcd as cdab, silently
[0:07] <Tv> that was a pain to find
[0:10] <cmccabe> nommu just sounds like a painful environment in general
[0:10] <Tv> oh yes
[0:10] <Tv> but cheap hardware = good for mass market
[0:10] <Tv> a lot of embedded companies choose to burn sw dev time instead
[0:11] <cmccabe> depends on how many units you expect to sell I guess
[0:11] <Tv> yeah #1 target market they listed was "China"
[0:11] <Tv> as in, china, period

[1:52] <Tv> so cmon mkfs now has now failed for me twice in a row
[1:53] <gregaf> yeah, it's crashing after some recent pushes to master
[1:53] <gregaf> cmccabe
[1:54] <gregaf> my push for mon tells is a little busted too because of how I tried to send repeat messages, but now I'm having trouble testing my fix :(

[20:33] <bchrisman> my take on the chdir code in Client.cc is that it's changing the directory and we basically lose the root of the filesystem at that point? is there a pointer to the root in the object so we can add some basic logic like "if (test for fullpath), set current dir to the root then ???."
[20:33] <bchrisman> right now if you chdir(/foo/bar) and then chdir(/foo), it's looking for /foo/bar/foo
[20:34] <Tv> bchrisman: that logic belongs in Client::chdir
[20:34] <Tv> (sorry if that's what you meant already)
[20:35] <bchrisman> yup...
[20:35] <Tv> "Warning: failed to parse error message from AWS: <unknown>:1:49: syntax error"
[20:35] <bchrisman> need to get a reference to the root though.. was wondering if that's stored somewhere in the object.
[20:35] <Tv> ohh crap
[20:35] <Tv> (that's rgw not aws)
[20:36] <Tv> whee 500 infernal server errors
[20:39] * lxo (~aoliva@186.214.48.116) has joined #ceph
[20:41] <yehudasa> Tv: how did you get the 500?
[20:41] <Tv> bucket creation or delete
[20:41] <Tv> don't yet know if it'll reproduce
[20:41] <Tv> but it's all going in s3-tests
[20:41] <yehudasa> hmm.. might be that Carl is doing something
[20:41] <Tv> i'm not using dho
[20:41] <yehudasa> oh
[20:42] <yehudasa> so what are you using?
[20:42] <Tv> vstart
[20:42] <yehudasa> do you have apache configured?
[20:42] * yoshi (~yoshi@KD027091032046.ppp-bb.dion.ne.jp) has joined #ceph
[20:42] <Tv> oh come on
[20:42] <Tv> all the existing s3-tests either work, or are flagged fails_on_rgw
[20:42] * yoshi (~yoshi@KD027091032046.ppp-bb.dion.ne.jp) Quit (Remote host closed the connection)
[20:43] <yehudasa> what version is installed on the gateway?
[20:43] <Tv> 1376a5ab0c89780eab39ffbbe436f6a6092314ed
[20:44] <Tv> anyway, i'll report it if it's reproducible etc
[20:48] <Tv> yeah it's not the test it's the rgw in this ceph version
[20:53] <yehudasa> yeah.. looking at it now
[20:54] <Tv> alright s3-tests have gotten a lot of new stuff today
[20:54] <yehudasa> actually it looks like something I've seen before and fixed
[20:54] <Tv> i recommend a pull
[20:54] <yehudasa> it's a problem in librados refcounting
[20:56] <yehudasa> oh.. sage probably merged something and this fix wasn't in his branch
[20:56] <yehudasa> I'll cherry pick
[21:00] <yehudasa> Tv: pushed a fix
[21:07] <Tv> sweet

[23:40] <Tv> today's verbal exercise commit message: "Properly package the python bindings."
[23:56] <Tv> sagewk1: i pushed branch deb-pybind, i'm still running tests to see if it does the right thing, but if you can launch deb builds on older debians that'd be appreciated
[23:56] <Tv> sagewk1: note changed build-deps
