#20532 [NEW]: proc_open connection hangs

From: chergr@bigpond.com Operating system: Linux Redhat 7.3 PHP version: 4.3.0RC1 PHP Bug Type: Program Execution Bug description: proc_open connection hangs The example in the manual that invokes the cli version of php works. But If I try to do the same thing with R (the statistics package at www.r-project.org) it hangs. Almost the same problem with bc -- output is only seen there if the fwrite connection is closed before doing an fread/fget. R buffers its output in non-terminal mode so I have tried modifying the source of R to force line-buffered output -- no joy. I have also tried calling R indirectly via the unbuffer script that comes with expect -- no joy. I have also tried the pty example program from "Advanced Programming in the Unix environment -- no joy. -- Edit bug report at http://bugs.php.net/?id=20532&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=20532&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=20532&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=20532&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=20532&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=20532&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=20532&r=support Expected behavior: http://bugs.php.net/fix.php?id=20532&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=20532&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=20532&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=20532&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=20532&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=20532&r=dst IIS Stability: http://bugs.php.net/fix.php?id=20532&r=isapi
