[TYPO3-core] FYI: Fixes & changes to caching framework in FLOW3

[Karsten Dambekalns]

Hi.

Yesterday and today I worked on the caching framework in FLOW3. Some  
of this is cleanup work, but there are also some important bugfixes  
(marked with ! in the following list). Here is a summary in reverse  
chronological order:

http://forge.typo3.org/repositories/revision/16/1805
  * added setter for default lifetime to AbstractBackend
  ! fixed handling of unlimited default lifetime in all three backend  
implementations (refs #1843, refs #1844)
  * the default cache configuration (Caches.yaml) now sets unlimited  
expiry time, should help against exception 1229362833

http://forge.typo3.org/repositories/revision/16/1803
  * moved and renamed cache frontend classes and interfaces, refs #2515

http://forge.typo3.org/repositories/revision/16/1802
  * removed wildcard support (from documentation) in getByTag() and  
findIdentifierByTag()
  * moved some methods, constants and checks to better-fitting places

http://forge.typo3.org/repositories/revision/16/1798
  * added cache backend for using the "Alternative PHP Cache" (APC)

http://forge.typo3.org/repositories/revision/16/1797
  * moved and renamed some cache backend classes and interfaces, refs  
#2515

http://forge.typo3.org/repositories/revision/16/1796
  ! now handles values larger than 1 MB and flush()es only the current  
cache's entries
  * uses SystemLogger for some operations
  * accepts "tcp://" prefix for hostnames and uses default port from  
php.ini if none given
  ! fixed handling of flags given to set(), enables compression
  ! memcache keys longer than 250 characters raise an exception now  
instead of being silently trunacted

I thought it might be of interest to keep the code in sync as much as  
possible or at least to profit from the bug fixes. Whoever takes care  
of the cache backport, feel free to contact me for more info if needed.

Happy coding,
Karsten
