#11023 [Com]: exec does not wait for completion of cmd

ID: 11023 Comment by: lars at erhardsen dot dk Reported By: terry at advertwizard dot com Status: Closed Bug Type: Program Execution Operating System: slackware 7 PHP Version: 4.0.5 New Comment: I think, I have a similar problem. The scenary is: Linux 2.4.22, Apache 2.0.48, PHP 4.3.4 on a Pentium 4, 2.4ghz, 512 mb ram The page continues without the 'output' from exec thus leaving an incomplete page. If I press f5/refresh, some times it works, other times it does not work. I have also placed sleeps between commands to ensure it works well. My php config: ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-gd=/usr/local --with-pdflib=/usr/local --with-mysql --with-config-file-path=/etc/apache2 --with-session --with-zlib-dir=/usr --with-png-dir=/usr/lib --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-tiff-dir=/usr --with-system-regex=yes --enable-debug=no --with-xml --with-imap-ssl=/usr/local/imap-2002d --enable-exif --with-openssl --with-gettext --enable-ftp --enable-sysvsem --enable-sysvshm --enable-calendar --enable-bcmath --enable-sockets --enable-track-vars --with-mcrypt --enable-gd-native-ttf --enable-mbstring --enable-gd-native-ttf My Apache config: ./configure --enable-ssl --enable-rewrite --enable-so --enable-info --enable-suexec --with-suexec-caller=nobody --enable-dav --enable-deflate Previous Comments: ------------------------------------------------------------------------ [2002-01-12 06:47:36] lobbin@php.net No feedback, closing. ------------------------------------------------------------------------ [2001-12-22 07:04:10] lobbin@php.net Does this happen on 4.1.0? R. ------------------------------------------------------------------------ [2001-05-22 13:14:30] terry at advertwizard dot com $cmd = "mv " . SITES_IMP . "site_* " . DB_UPDATES; exec($cmd); $arr = array(); $cmd = "ls " . DB_UPDATES . " site_* | wc -l"; exec($cmd,$arr); i am of the impression that code proceeding an exec cmd will not execute until the exec is finished in the above instance, the "ls" exec is executing before the "mv" exec has finished - when i know that 10 files have been moved, the "ls" exec returns 0 for a "wc -l", when running the code again it returns the number of files correctly - have placed sleeps between the commands and all works well wondered if this is a bug in the exec cmd or my misunderstanding of its use ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=11023&edit=1
