2011-09-27Cache: fix for sending of empty responses.Maxim Dounin1-3/+5
Revert wrong fix for empty responses introduced in 0.8.31 and apply new one, rewritten to match things done by static module as close as possible.
2011-08-25Cache size accounting fix: actual cache size on disk was less thanIgor Sysoev1-0/+1
needed by sum of sizes of files loaded by worker processes themselves while cache loader was running. The bug has been introduced in r3900.
2011-08-22The change in adaptive loader behaviour introduced in r3975:Igor Sysoev1-40/+26
now cache loader processes either as many files as specified by loader_files or works no more than time specified by loader_threshold during each iteration. loader_threshold was previously used to decrease loader_files or to increase loader_timeout and this might eventually result in downgrading loader_files to 1 and increasing loader_timeout to large values causing loading cache for forever.

2011-07-25rename ngx_http_file_cache_manager_sleep() to ngx_http_file_cache_loader_sleep()Igor Sysoev1-4/+4
and do not use it all in cache manager: this is a vestige of the times when cache manager loaded cache
2011-07-24do not close connection if cache file is too small: replace it with valid oneIgor Sysoev1-1/+1
2011-07-24elimination of reading cache files by cache loaderIgor Sysoev1-42/+9

2011-07-24update the previous commit:Igor Sysoev1-2/+1
removing dependencies on file uniq since WIN32_FIND_DATA has no such field
2011-07-24The cache loader performs two tasks: inserting cache objects in inactivityIgor Sysoev1-11/+6
list and evaluating total cache size. Reading just directory is enough for this purpose. Elimination of reading cache files saves at least one disk I/O operation per file. Preparation for elimination of reading cache files by cache loader: removing dependencies on the reading: *) cache node valid_sec and valid_msec are used only for caching errors; *) upstream buffer size can be used instead of cache node body_start.

2011-05-13fix a broken cached response if bypass/no_cache directive values are different,Igor Sysoev1-3/+1
the bug has been introduced in r3700
2011-04-22Use more precise stat.st_blocks to account cache size on UnixIgor Sysoev1-17/+14
instead of file length rounded to a file system block size. There is no similar way on Windows, so rounding to a cache->bsize is kept.

2010-09-02fix race condition if during reconfiguration two cache managers tryIgor Sysoev1-0/+8
to delete old inactive entries: one of them removes a entry just locked by other manager from the queue and the rbtree as long inactive entry, causes the latter manager to segfault leaving cache mutex locked, the bug has been introduced in r3727

2010-07-28several changes in cache cleanup handling:Igor Sysoev1-23/+17
*) now ngx_http_file_cache_cleanup() uses ngx_http_file_cache_free() *) ngx_http_file_cache_free() interface has been changed to accept r->cache ngx_http_file_cache_cleanup() must use r->cache, but not r, because there can be several r->cache's during request processing, r->cache may be NULL at request finalising, etc. *) test if updating request does not complete correctly
2010-07-27fix r3708 and r3695: valid_sec is set only for caching error status codesIgor Sysoev1-1/+1
2010-07-27fix r3695: this commitIgor Sysoev1-1/+1
*) freed valid keys zone node *) and did not decrease cache size, so cache manager process ete CPU time, if cache checking max_size was enabled
