Description Robert Vogelgesang 2010-09-30 09:55:50 UTC 
Created attachment 450704 [details]
Patch to clear the compression flag for integer, float, and boolean data

Description of problem:
php-pecl-memcache has a bug preventing the successful storage of integer, float,
or boolean values in memcached.

Version-Release number of selected component (if applicable):
php-5.3.2-4.el6.x86_64
php-pecl-memcache-3.0.4-3.2.el6.2.x86_64
memcached-1.4.4-3.el6.x86_64

How reproducible:
Always when storing and retrieving integer, float, or boolean values, with compression enabled.

Steps to Reproduce:
Example scripts that reproduce the bug can be found in upstreams bug tracker at:
http://pecl.php.net/bugs/bug.php?id=16442
  
Actual results:
Retrieving a stored value fails, the stored value is lost, and PHP logs a message with level NOTICE:
MemcachePool::get(): Failed to uncompress data

Expected results:
Retrieving a stored value should succeed and return the stored value.

Additional info:
The upstream author changed php-pecl-memcache so that compression is never used to store values of integer, float, and boolean types, but forgot to clear the compression flag in case it should be set.  Because of this, values that were stored this way fail decompression on retrieval, because they are not compressed in the first place.

The attached patch fixes the issue.

Upstream has released version 3.0.5 which contains the fix from the patch attached to this Bugzilla entry.  Please upgrade to the latest version.

Had to clear Rebase keyword to keep bot from resetting relnote flag - there is a relnote for this rebase, it is just attached to another bug fixed by the rebase
