* protect syslog against cancellationRich Felker2011-04-181-5/+19
| | | | | | these functions are allowed to be cancellation points, but then we would have to install cleanup handlers to avoid termination with locks held.
* simplify syslog, add vsyslog interface (nonstandard)Rich Felker2011-04-131-31/+36
| | | | | | | | with datagram sockets, depending on fprintf not to flush the output early was very fragile; the new version simply uses a small fixed-size buffer. it could be updated to dynamic-allocate large buffers if needed, but i can't envision any admin being happy about finding 64kb-long lines in their syslog...
* remove useless SIGPIPE protection from syslogRich Felker2011-04-131-9/+0
| | | | per the standard, SIGPIPE is not generated for SOCK_DGRAM.
* fix syslog (corrected SIGPIPE blocking, and using dgram instead of stream)Rich Felker2011-04-131-10/+8
| | | | | | it actually appears the hacks to block SIGPIPE are probably not necessary, and potentially harmful. if i can confirm this, i'll remove them.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+115
