|#152||fixed||Weird PHP errors when files get deleted and copied again (multiple times in cache)||moo||blueyed|
I have a demo setup for a PHP application and to reset it, I'm removing all files and copying them anew ("rm /path/to/app -rf && cp -a /source /path/to/app").
This causes weird PHP errors like "call to undefined function", "cannot redeclare foo()" or "Class 'DataObject?' not found".
After removing the xcache cache, it works again.
Looking at the cached files, there a duplicates, e.g.:
php#0 71 /path/inc/generic/model/_genericcache.class.php 0 0 6.04 K 2.79 K 4 M 2051 508796 8 m 8 m php#0 72 /path/inc/generic/model/_genericcache.class.php 2 0 6.04 K 2.79 K 4 M 2051 508795 10 s 8 m
I'm not sure if this is related to the PHP files being accessed during "deletion" and have not tried to create a smaller testcase.
I've tried using xcache.readonly_protection=On, but it still broke.
A workaround appears to be using "/bin/cp -a --no-preserve=timestamps" to copy the files to the same place again (--no-preserve=timestamps is the key here).
xcache.admin.enable_auth On xcache.cacher On xcache.coredump_directory no value xcache.count 1 xcache.gc_interval 0 xcache.mmap_path /dev/zero xcache.readonly_protection 1 xcache.shm_scheme mmap xcache.size 10M xcache.slots 8K xcache.stat On xcache.test 0 xcache.ttl 0 xcache.var_count 1 xcache.var_gc_interval 120 xcache.var_maxttl 0 xcache.var_size 64K xcache.var_slots 8K xcache.var_ttl 0
I'm using the 1.2 branch and PHP_5_2 (both uptodate).
|#185||worksforme||Using a php script for sendmail_path causes segmentation fault||moo||blueyed|
I've noticed that "mail()" failed on my webserver, since I've installed XCache:
# php -d sendmail_path="/usr/local/bin/sendmail_test" -r "var_dump( mail('EMAIL', 'test', 'test') );" /dev/zero: No space left on device Failed creating file mappping PHP Fatal error: Failed creating file mappping in Unknown on line 0 PHP Fatal error: XCache: Cannot create shm in Unknown on line 0 testSegmentation fault bool(false)
/usr/local/bin/sendmail_test looks as follows:
#!/usr/bin/php <?php echo "test"; ?>
Executing sendmail_test itself works fine, only when used for sendmail_path it fails.
The workaround for me is to use "#!/usr/bin/php -n" for this script (-n for "no ini and therefore also no xcache). Debian/Ubuntu? uses the same conf.d directories for CLI and CGI, otherwise I might have disabled XCache for CLI instead.
If you need more information, like e.g. a backtrace in case you cannot reproduce this, please let me know.
|#323||fixed||segfaults when using XCache 3.0.3 under heavy load||moo||boxdev|
Hi. I am working with David Schnepper from Box to troubleshoot segfaults on our site. He previously worked with you on XCache 2.0.1. You took his fixes for XCache 2.0.1 and created XCache 3.0.3. Box upgraded to XCache 3.0.3 but we are still seeing the segfaults.
I have attached some stack traces. We would appreciate your feedback on what other data we can gather.
