* Give up on the "try and compensate for broken programs" cruft and revertPeter Wemm1997-10-151-70/+0
| | | | | | | | | | | | | | | | back to the original single nanosleep() implementation. This is POSIX and Unix98 (aka single-unix spec v2) compliant behavior. If a program sets alarm(2) or an interval timer (setitimer(2)) without a SIGALRM handler being active, sleep(3) will no longer absorb it, and the program will get what it asked for..... :-] The original reason for this in the first place (apache) doesn't seem to need it anymore, according to Andrey.

* Back out my installation of SIGALRM handler even if it is blockedAndrey A. Chernov1997-08-121-19/+29
| | | | | | | | | | and return to previous Peter's variant. POSIX says that this place is implementation defined and old variant allows application block SIGALRM and sleep and not be killed by external SIGALRMs. BTW, GNU sleep f.e. sleeps forever in blocked SIGALRM :-) Notes: svn path=/head/; revision=28125

* Re-activate the nanosleep style using code, but with the signal handlingPeter Wemm1997-06-021-53/+1
| | | | | | | | | | | | | semantics of the old sleep for compatability with a few decades of expected side effects. Apache breaks if we just use nanosleep() for some reason, here we use a new signanosleep() syscall which is kinda like a hybrid of sigsuspend and nanosleep.. Reviewed by: ache (and tested on his apache that was failing when sleep used plain nanosleep) Notes: svn path=/head/; revision=26385

| | | | | | | | | | -DUSE_NANOSLEEP. Also, seperate the code for _THREAD_SAFE so that it uses the simpler threaded nanosleep() call in libc_r.. We don't go to the same extremes for emulating traditional sleep semantics (ie: eating any SIGALRM that might happen) which things like apache seem to depend on. Notes: svn path=/head/; revision=26338
* Update the nanosleep versions to set a SIGALRM handler while sleeping.Peter Wemm1997-05-181-2/+9
| | | | | | | | This appears to appease Apache, although depending on having sleep(3) changing the SIGALRM handler is a bit bogus. Notes: svn path=/head/; revision=25890

| | | | | | | | | | | | | | | | | | (nanosleep) breaks Apache httpd badly: his childs died quickly after number of requests (SIGPIPE). To reproduce this bug start gdb /usr/local/sbin/httpd run -X and make some bunch of concurent requests (load the server pages from 3 different places f.e.) After short time httpd dies via SIGPIPE. It never dies with old sleep.c In real life it looks like lots of broken images on the pages or missing pages. Lynx says about Network read error, etc. It seems something wrong in nanosleep signal handling. Notes: svn path=/head/; revision=25861
