Switch to exclusively using global ctx

2014-01-16T23:44:54Z

Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_print_http_headers() * cgit_print_docstart() * cgit_print_pageheader() Remove context parameter from all commands Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_get_cmd() * All cgit command functions. * cgit_clone_info() * cgit_clone_objects() * cgit_clone_head() * cgit_print_plain() * cgit_show_stats() In initialization routines, use the global context variable instead of passing a pointer around locally. Remove callback data parameter for cache slots This is no longer needed since the context is always read from the global context variable. Signed-off-by: Lukas Fleischer

use attribute to catch printf format mistakes

2010-09-04T15:11:40Z

Use "__attribute__((format (printf,N,M)))", as is done in git, do catch mistakes in printf-style format strings. Signed-off-by: Mark Lodato

cache.h: export hash_str()

2009-08-24T08:22:57Z

This function will be reused to cache the result of tree scanning. Signed-off-by: Lars Hjemli

Add page 'ls_cache'

2008-04-28T10:10:13Z

This new page will list all entries found in the current cache, which is useful when reviewing the new cache implementation. There are no links to the new page, but it's reachable by adding 'p=ls_cache' to any cgit url. Signed-off-by: Lars Hjemli

Redesign the caching layer

2008-04-28T09:32:42Z

The original caching layer in cgit has no upper bound on the number of concurrent cache entries, so when cgit is traversed by a spider (like the googlebot), the cache might end up filling your disk. Also, if any error occurs in the cache layer, no content is returned to the client. This patch redesigns the caching layer to avoid these flaws by * giving the cache a bound number of slots * disabling the cache for the current request when errors occur The cache size limit is implemented by hashing the querystring (the cache lookup key) and generating a cache filename based on this hash modulo the cache size. In order to detect hash collisions, the full lookup key (i.e. the querystring) is stored in the cache file (separated from its associated content by ascii 0). The cache filename is the reversed 8-digit hexadecimal representation of hash(key) % cache_size which should make the filesystem lookup pretty fast (if directory content is indexed/sorted); reversing the representation avoids the problem where all keys have equal prefix. There is a new config option, cache-size, which sets the upper bound for the cache. Default value for this option is 0, which has the same effect as setting nocache=1 (hence nocache is now deprecated). Included in this patch is also a new testfile which verifies that the new option works as intended. Signed-off-by: Lars Hjemli

Add cache.h

2008-03-27T08:22:13Z

The functions found in cache.c are only used by cgit.c, so there's no point in rebuilding all object files when the cache interface is changed. Signed-off-by: Lars Hjemli
