I started poking through perl documentation and found this in README.solaris The stdio(3C) manpage notes that only 255 files may be opened using fopen(), and only file descriptors 0 through 255 can be used in a stream. Since perl calls open() and then fdopen(3C) with the resulting file descriptor, perl is limited to 255 simultaneous open files. ---- So we should choose one of the following possibilities: a) use only open() and not fopen(), which should be possible beacuse later in streams.c only the read file descriptor is obtained with fileno(). Why also use fopen? b) in solaris use parts of glibc which handles fopen-streams. ------------------------------------------------------------------------ [2003-03-08 06:25:15] thetaphi@php.net I will test it with PHP5 on out solaris box. ------------------------------------------------------------------------ [2003-03-07 20:01:28] wez@php.net It's in PHP_4_3 branch. The problem does not apply to PHP5, as the ZE2 no longer needs to cast/clone streams. ------------------------------------------------------------------------ [2003-03-07 11:52:36] thetaphi@php.net wez@thetaphi.net: The fix you explained: Is it also in the 4.3 CVS? Or only in newest one? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
