Patch by Austin Donnelly <austin@gimp.org> to address #2742. (I took
|
||||
the liberty of moving it to libgimp for general consumption, & fixed a
|
||||
typo) SYS5R4 unix's were failing when signals arrived at processes in
|
||||
system calls, a behavior in accordance with POSIX specs. Patch
|
||||
introduces a gimp_signal_private() workalike replacement for
|
||||
signal(2), layered over sigaction(2) which internally requests the
|
||||
signal environment to restart system calls instead of failing. This is
|
||||
POSIX spec 1170 extension behavior, but one that appears to be generally
|
||||
supported. Thanks due to Tim Mooney <mooney@dogbert.cc.ndsu.nodak.edu>
|
||||
for testing this on various flavors of OSF/1 boxes where #2742 seemed
|
||||
especially common.

/**
|

* gimp_signal:
|
||||
* @signum: selects signal to be handled see man 5 signal
|
||||
* @handler: handler that maps to signum. Invoked by O/S.
|
||||
* handler gets signal that caused invocation.
|
||||
* @sa_flags: preferences. OR'ed SA_<xxx>. See signal.h
|
||||
*
|
||||
* This function furnishes a workalike for signal(2) but
|
||||
* which internally invokes sigaction(2) after certain
|
||||
* sa_flags are set; these primarily to ensure restarting
|
||||
* of interrupted system calls. See sigaction(2) It is a
|
||||
* aid to transition and not new development: that effort
|
||||
* should employ sigaction directly. [<gosgood@idt.net> 18.04.2000]
|
||||
*
|
||||
* Cause handler to be run when signum is delivered. We
|
||||
* use sigaction(2) rather than signal(2) so that we can control the
|
||||
* signal hander's environment completely via sa_flags: some signal(2)
|
||||
* implementations differ in their sematics, so we need to nail down
|
||||
* exactly what we want. [<austin@gimp.org> 06.04.2000]
