WINCACHE_FCACHE_FILEINFO(3) 1 WINCACHE_FCACHE_FILEINFO(3)wincache_fcache_fileinfo - Retrieves information about files cached in the file cacheSYNOPSIS
array wincache_fcache_fileinfo ([bool $summaryonly = false])
DESCRIPTION
Retrieves information about file cache content and its usage.
PARAMETERS
o $summaryonly
- Controls whether the returned array will contain information about individual cache entries along with the file cache summary.
RETURN VALUES
Array of meta data about file cache or FALSE on failure
The array returned by this function contains the following elements:
o total_cache_uptime - total time in seconds that the file cache has been active
o total_file_count - total number of files that are currently in the file cache
o total_hit_count - number of times the files have been served from the file cache
o total_miss_count - number of times the files have not been found in the file cache
o file_entries - an array that contains the information about all the cached files:
o file_name - absolute file name of the cached file
o add_time - time in seconds since the file has been added to the file cache
o use_time - time in seconds since the file has been accessed in the file cache
o last_check - time in seconds since the file has been checked for modifications
o hit_count - number of times the file has been served from the cache
o file_size - size of the cached file in bytes
EXAMPLES
Example #1
A wincache_fcache_fileinfo(3) example
<pre>
<?php
print_r(wincache_fcache_fileinfo());
?>
</pre>
The above example will output:
Array
( [total_cache_uptime] => 3234
[total_file_count] => 5
[total_hit_count] => 0
[total_miss_count] => 1
[file_entries] => Array
(
[1] => Array
(
[file_name] => c:inetpubwwwrootcheckcache.php
[add_time] => 1
[use_time] => 0
[last_check] => 1
[hit_count] => 1
[file_size] => 2435
)
[2] => Array (...iterates for each cached file)
)
)

DWWW-CACHE(8) Debian DWWW-CACHE(8)NAME
dwww-cache - manage the dwww cache of converted documents
SYNOPSIS
dwww-cache --lookup type location
dwww-cache --store type location
dwww-cache --list type location
dwww-cache --list-all
dwww-cache --clean
DESCRIPTION
dwww-cache manages the cache of converted documents; it is part of dwww(7). An option (the first argument) specifies the operation. Some
operations operate on the whole cache, and need no other arguments. Others need the second and third argument to specify the type and
pathname of the original document. (See dwww-convert(8) for more information about the arguments.)
The operations are:
--lookup
If the document is in the cache, output it to the standard output. Otherwise, output nothing and return a non-zero status.
--store
Read the document from the standard input, output it to the standard output and store it into the cache. If there was an older ver-
sion already in the cache, remove it.
--list Output information about one document in the cache to the standard output. The information is one line, with four space delimited
fields: type, pathname of original, pathname of cached, and permanent flag (y or n).
--list-all
Like --list, but for all documents.
--clean
Forget all cached documents that have been deleted.
dwww-cache maintains a database with information of the cached documents. The documents themselves are stored in separate files in the
cache directory. When old documents are removed from the cache by a suitable crontab entry, they will still exist in the database. This
operation removes all entries from the database where either the original or the converted file is now missing.
To stop the cache from growing too large, an entry in root's crontab should remove cached files that have not been accessed for a while.
For example, the following commands remove all documents that have not been accessed for ten days:
find /var/cache/dwww -atime +10 | xargs rm -f
dwww-cache --clean
The idea is to first delete the old cached files and then clean up the database. The policy of cleaning the cache has been kept outside of
dwww-cache to keep the program simple, and to allow maximum flexibility. The default dwww installation creates a /etc/cron.daily/dwww,
which automatically cleans the cache each day.
FILES
/var/cache/dwww/db
The cache directory.
/var/cache/dwww/db/.cache_db
The database with information about all cached documents. This is a binary file, specially encoded for small size and high speed,
and should not be touched by anyone but dwww-cache.
