[15:01:08] <jepler> it could be a sign the lockfree queue "backport" is not right

[15:06:40] <cradek> I have a machine up that's running wheezy on the linuxcnc 3.4.55-4linuxcnc rtai kernel. can that help?
[15:09:12] <jepler> cradek: maybe. I don't know if the uspace+rtai build works there at all, so it would be an interesting data point

[15:15:15] <seb_kuzminsky> i wanted to wait a little bit after that hairy Task fix/breaking i did, to see what else needs fixing
[15:16:51] <seb_kuzminsky> the original commits were in early June, the one bugfix since then was July 1
[15:17:16] <seb_kuzminsky> so maybe i should muster my courage and just release it
[15:17:47] <seb_kuzminsky> i'm super grateful to Gene Heskett for finding and reporting the bug
[15:19:14] <seb_kuzminsky> uhm, so maybe tuesday (tomorrow) at the hackspace i'll do it
[15:26:56] <cradek> Running test: tests/module-loading/rtapi-app-main-fails
[15:26:57] <cradek> loadrt did not find the test component
[15:26:57] <cradek> *** tests/module-loading/rtapi-app-main-fails: FAIL: checkresult exited with 1
[15:27:31] <cradek> jepler: what am I missing? this is branch jepler/master/uspace-plus built from clean
[15:29:14] <jepler> cradek: isn't that the error from buildbot? so it seems generally to affect wheezy, :(
[15:29:51] <jepler> what's happening is, some rtapi_print messages are going missing...
[15:30:23] <jepler> they go through this new queue thing so they can get out of real-time without making syscalls...
[15:35:46] -!- Daerist has quit [Quit: Leaving]
[15:39:55] <cradek> ok, it's failing every time on wheezy+rtai
[15:41:25] <cradek> wait,
http://paste.ubuntu.com/19086935/
[15:42:28] <seb_kuzminsky> heh
[15:42:36] <seb_kuzminsky> the module failed to load, but not like it should
[15:42:51] <cradek> first (real?) failure:
http://paste.ubuntu.com/19087032/
[15:42:56] <seb_kuzminsky> is that a negative false positive?
[15:43:03] <cradek> so confused
[15:43:43] <cradek> jepler: if I'm not helping, just tell me to stop

[15:47:54] <jepler> I don't even understand that second failure...
[15:48:22] <cradek> that's after I ran /etc/init.d/realtime stop manually to unload the stuck rtai modules
[15:48:49] <jepler> either of the failures you pasted in fact
[15:48:51] <cradek> the failure leaves 3 rtai modules loaded
[15:50:29] <jepler> there are at least two problems then. maybe stop helping for now...
[15:50:53] <cradek> ok
[15:51:34] <jepler> thanks though!
[15:51:38] <cradek> welcome
[16:28:21] -!- mk0 [mk0!~mk0@37.17.114.217] has joined #linuxcnc-devel
[16:46:42] <jepler> ISTM that the original failure (not seeing the specific load-failed error message) indicates that the backported boost stuff is not right.
[16:55:50] <jepler> no, it's not just the backport. I get eventual failures on my jessie system too, just took more than 4096 tries
[16:56:39] <seb_kuzminsky> i'm amused at your {,,,}
[16:57:02] <seb_kuzminsky> so something good has come out of all your hard work
[16:57:05] <jepler> it's not an elegant way to say it, but it works and it has become a habit
[16:57:23] <seb_kuzminsky> it's a lot less typing that writing a for loop in bash
[16:57:39] <jepler> yeah but it destroys the evidence
[16:57:52] <jepler> need to add an option: runtests --ttf (test-to-failure)
[16:58:07] <jepler> or something
[16:58:16] <jepler> or just stop-at-first-failure
[16:58:52] <jepler> sigh I hate 1-in-100-or-less bugs
[17:09:23] <jepler> "pthreads is stranger than we can imagine"
[17:10:28] <jepler> .. I have found an additional problem with my use of pthreads that would explain this test failure
[17:10:48] <jepler> I was unaware of the fact that a thread could get canceled in the middle of a printf(3) / write(2)
[17:11:14] <jepler> so the behavior is: message gets pulled off queue, write(2) syscall starts, thread gets canceled -> message is lost
[17:11:56] <jepler> I'll let this run to 10,000 iterations if it doesn't fail first
[17:12:03] <jepler> or one lunch of iterations

This will prevent RCU callbacks from ever being invoked, and in a CONFIG_PREEMPT_RCU kernel will further prevent RCU grace periods from ever completing. Either way, the system will eventually run out of memory and hang.

[22:55:06] <jepler> seb_kuzminsky: I've been trying to get the uspace builds from my branch to automatically pick up whether to build rtai or xenomai support based on info from apt-cache, but now I see two things: first, <distro>/base isn't in source.list (based on searching in
http://buildbot.linuxcnc.org/buildbot/builders/1400.rip-wheezy-i386/builds/2495/steps/apt-get-update/logs/stdio) and anyway the metadata might
[22:55:12] <jepler> not be there yet since apt-get update is after configure debian/control
[23:05:21] <seb_kuzminsky> jepler: you want to see if a xenomai kernel is available in the apt sources, but you don't care what's currently running on the build host?
[23:07:16] <seb_kuzminsky> i think it's likely i left the 'linuxcnc.org $DIST base' out of sources.list, since it was not needed at the time i set the wheezy machines up
[23:07:21] <seb_kuzminsky> that's probably a bug on my part
[23:11:06] <jepler> seb_kuzminsky: rtai, actually. xenomai development files are available in the base system on x86 even if no kernels are
[23:11:16] <jepler> (xenomai have a stable ABI while rtai is :shrug: about ABI)

[23:46:35] <jepler> hm
[23:47:25] <jepler> I guess it uses the same .dscs for i386, amd64, and armhf builds (how can it not) so it ends up requiring libxenomai-dev on armhf
