I have found a funky situation that I am trying to figure out if it is bug or not:
I see this behavior on both redhat 9 and fedora running php 4.3.4 httpd(apache) 2.0.48 calling umask(0002) in a script leaves the httpd process with a umask of 2 after exit so that the next process to hit that process gets the new umask. in other words the environment does not revert to default as the umask() docs say it should. This does not happen on my 7.3 box running apache-1.3.27-2 php-4.1.2-7.3.6 I found this chasing a rabbit trail of a bug. This is kind of sneaky since it only changes the umask for the single httpd process it hits. multiple calls to umask(0002) will change every process it hits. I distilled this down to this test: BTW this is also file at buzilla.redhat.com as bug number 121454: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=121454 1.install umask.php in a directory accessible by the web server ####### umask.php <?php if ( isset( $_GET['newmask']) ) { print "newmask is set to $_GET[newmask] calling umask()<br>\n"; print umask($_GET['newmask']) ."<br>\n"; } else { print "umask is ". umask() . "<br>\n"; } ?> ################# end of umask.php 2. copy chkmask.sh somwhere on the server ########## chkumask.sh #!/bin/sh if [ -n "$1" ] ; then echo "setting hostname to input host $1" myhost=$1 else myhost=$HOSTNAME fi echo "using $myhost as wget host" while [ 1 ]; do echo -n `date +'%D'` " host: $myhost " wget -q -O - "http://$myhost/umask.php"; sleep 1 done ############ end of of chkumask.sh 3. run chkumask.sh [hostnameofserver] this will start looping and making calls to the umask.php script on the server defaults to value of $HOSTNAME 4. with a broser or whatever go to http://servername/locationofumask.php?newmask=0002 5 observe output of chkumask.sh depending on the number of threads started by httpd the umask changes from 18(octal 22, the default) to 2 for that thread. refresh the browser several times to have more threads get changed. Actual Results: output of chkumask.sh: using 10.23.0.137 as wget host 04/21/04 host: 10.23.0.137 umask is 2<br> 04/21/04 host: 10.23.0.137 umask is 18<br> 04/21/04 host: 10.23.0.137 umask is 2<br> 04/21/04 host: 10.23.0.137 umask is 2<br> 04/21/04 host: 10.23.0.137 umask is 18<br> 04/21/04 host: 10.23.0.137 umask is 18<br> 04/21/04 host: 10.23.0.137 umask is 18<br> 04/21/04 host: 10.23.0.137 umask is 2<br> 04/21/04 host: 10.23.0.137 umask is 2<br> 04/21/04 host: 10.23.0.137 umask is 18<br> 04/21/04 host: 10.23.0.137 umask is 2<br> any tips appreciated as well as report wither the behavior is seen or not on various versions. I am trying to isolate when this behavior started or what I have done wrong. Bret -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
