Hi,
I'm using uWSGI 0.9.7.2 on MacOS 10.6.7. When I try to gracefully reload the
code of my workers using SIGHUP, I get the following output from uWSGI:
<some output snipped>
binary reloading uWSGI...
closing all non-uwsgi socket fds > 2 (_SC_OPEN_MAX = 2560)...
found fd 18 mapped to socket 0 (/tmp/audish/uwsgi.sock)
<no more output beyond this point>
...and then the process hangs. In /var/log/system.log, these lines appear:
Apr 10 18:47:38 host /usr/local/bin/uwsgi[25911]: BUG in libdispatch:
10J869 - 1986 - 0x4 Apr 10 18:47:40 host ReportCrash[25939]: Saved crash
report for uwsgi[25911] version ??? (???) to
/Users/user/Library/Logs/DiagnosticReports/uwsgi_2011-04-10-184740_host.crash
And in
/Users/user/Library/Logs/DiagnosticReports/uwsgi_2011-04-10-184740_host.crash,
the most important line (I believe) is:
Application Specific Information:
BUG IN CLIENT OF LIBDISPATCH: Do not close random Unix descriptors
I'm fairly convinced that the socket closing code in master.py should be
modified so as not to upset libdispatch, but I'm still not entirely sure how
to go about doing it (maybe I'll play with it more and see if I can find a
patch later today).
Is this a known bug? Is there a known workaround? How can I assist in
producing a fix?
Cheers,
- Yaniv
