Umpf... we really need a mailinglist... ... this has already been discussed with various proposed solutions, including: - dlload() of libshell.so (which may save the whole mess with fork()&co. and therefore avoid the related overhead) ... this is also my preferred solution... :-) - dlload() of libast which already provides a version of |wordexp()| - Usage of the libast |wordexp()| code in libc directly > If you amend your proposal to that effect, I will second it. Yes, that would be done as part of that project, too. I would prefer a 2-stage fix for this: 1. Use dlload() of libshell.so in a fork()'ed child process - this has the advantage that it doesn't need much work, preserves MT-safeness, abuses the child process to do the garbage collection when it terminates (yes, I know... that's ugly) and also allows easy testing for regressions... 2. Work-out a version which no longer needs the |fork()| - which means there needs to be a mutex and somehow a clever way to do the garbage collection (e.g. freeing resources like memory etc.) in a way which doesn't cause a performance it when being done in a tight loop. ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
