* Convert KWSys to OSI-approved BSD LicenseBrad King2009-09-281-11/+9
| | | | | | | This converts the KWSys license to a pure 3-clause OSI-approved BSD License. We drop the previous license clause requiring modified versions to be plainly marked. We also update the KWSys copyright to cover the full development time range.
* ENH: Provide unix-sytle command line parsingBrad King2009-07-131-256/+3
| | | | | | | Add System_Parse_CommandForUnix to the KWSys System interface as a utility to parse a unix-style command line. Move the existing implementation out of ProcessUNIX. Add a flags argument reserved for future use in providing additional behavior.
* COMP: Do not compile VMS-specific code on non-VMSBrad King2009-06-121-8/+7
| | | | | This helps avoid fixing VMS-specific code for non-VMS compilers where it isn't needed anyway.

* ENH: Teach KWSys Process basic VMS supportBrad King2009-06-101-9/+76
| | | | | | | | | | | | | | This achieves basic process execution on OpenVMS. We use work-arounds for different fork()/exec() behavior and a lack of select(). VMS emulates fork/exec using setjmp/longjmp to evaluate the child and parent return cases from fork. Therefore both must be invoked from the same function. Since select() works only for sockets we use the BeOS-style polling implementation. However, non-blocking reads on empty pipes cannot be distinguished easily from the last read on a closed pipe. Therefore we identify end of data by an empty read after the child terminates.
* BUG: Fix non-select process impl without timeoutBrad King2009-06-101-12/+8
| | | | | This avoids use of an uninitialized value in the KWSys ProcessUNIX polling implementation when no timeout is given.

* BUG: Handle case when select() liesBrad King2008-08-201-7/+10
| | | | | | | According to "man select" on Linux it is possible that select() lies about data being ready on a pipe in some subtle cases. We deal with this by switching to non-blocking i/o and checking for EAGAIN. See issue #7180.

* BUG: Fix hang in Process_Kill on OS X caused by an OS bug in which a pipe ↵Brad King2008-01-101-39/+54
| | | | read end cannot be closed if the pipe write end is open, the pipe is full, and another process is blocking waiting to write. Work around the problem by killing the children before closing the pipes.

* BUG: Do not send both SIGSTOP and SIGKILL when killing a process. The ↵Brad King2007-05-161-5/+7
| | | | SIGSTOP seems to be able to block the SIGKILL occasionally. Also the SIGKILL is sufficient since the process table entry will still exist until it is reaped with waitpid.
