|
cacheDir
|
string
|
/tmp/
|
directory where to put the cache file
(with a trailing slash at the end)
|
|
caching
|
boolean
|
TRUE
|
enable / disable caching
|
|
lifeTime
|
integer
|
3600
|
cache lifetime in seconds (since 1.6.0beta 1, you can use a null value for an eternal cache lifetime)
|
|
fileLocking
|
boolean
|
TRUE
|
enable / disable fileLocking.
Can avoid cache corruption under bad circumstances.
|
|
writeControl
|
boolean
|
TRUE
|
enable / disable write control.
Enable write control will lightly slow the cache writing
but not the cache reading.
Write control can detect some corrupt cache files
but maybe it's not a perfect control.
|
|
readControl
|
boolean
|
TRUE
|
enable / disable read control.
If enabled, a control key is embeded in cache file
and this key is compared with the one calculated after the reading
|
|
readControlType
|
string
|
crc32
|
Type of read control (only if read control is enabled).
Must be
'md5' (for a md5 hash control (best but slowest)),
'crc32' (for a crc32 hash control (lightly less safe but faster))
or 'strlen' (for a length only test (fastest))
|
|
pearErrorMode
|
integer
|
CACHE_LITE_ERROR_RETURN
|
pear error mode
(when raiseError is called)
(CACHE_LITE_ERROR_RETURN for just returning
a PEAR_Error object
or CACHE_LITE_ERROR_DIE for
immediate stop of the script (good for debug) )
|
|
fileNameProtection
|
boolean
|
TRUE
|
file Name protection
(if set to true, you can use any cache id or group name,
if set to false, it can be faster but cache ids and group
names will be used directly in cache file names so be carefull with
special characters...)
|
|
automaticSerialization
|
boolean
|
FALSE
|
enable / disable automatic serialization
(it can be used to save directly datas
which aren't strings but it's slower)
|
|
memoryCaching
|
boolean
|
FALSE
|
enable / disable "Memory Caching"
(NB : there is no lifetime for memory caching,
only the end of the script)
|
|
onlyMemoryCaching
|
boolean
|
FALSE
|
enable / disable "Only Memory Caching"
(if enabled, files are not used anymore)
|
|
memoryCachingLimit
|
integer
|
1000
|
max number of records to store into memory caching
|
|
automaticCleaningFactor
|
integer
|
0
|
Disable / Tune the automatic cleaning process.
The automatic cleaning process destroy too old
(for the given life time)
cache files when a new cache file is written.
0 means "no automatic cache cleaning",
1 means "systematic cache cleaning" (slow),
x>1 means "automatic cleaning randomly 1 times on x cache writes".
A value between 20 and 200 is maybe a good start.
|
|
hashedDirectoryLevel
|
integer
|
0
|
Set the hashed directory structure level.
0 means "no hashed directory structure",
1 means "one level of directory",
2 means "two levels"...
This option can speed up Cache_Lite
only when you have many thousands of cache file.
Only specific benchs can help you to choose the perfect
value for you.
Maybe, 1 or 2 is a good start.
|
|
errorHandlingAPIBreak
|
boolean
|
FALSE
|
If set to true, it introduces a little API break but the error handling
is better in CACHE_LITE_ERROR_RETURN mode (specially with the save()
method which can return a PEAR_Error object).
