* use __attribute__ to catch printf format mistakesMark Lodato2010-09-04
| | | | | | | Use "__attribute__((format (printf,N,M)))", as is done in git, do catch mistakes in printf-style format strings. Signed-off-by: Mark Lodato <lodatom@gmail.com>
* cache.h: export hash_str()Lars Hjemli2009-08-24
| | | | | | This function will be reused to cache the result of tree scanning. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Add page 'ls_cache'Lars Hjemli2008-04-28
| | | | | | | | 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 <hjemli@gmail.com>
* Redesign the caching layerLars Hjemli2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <hjemli@gmail.com>
* Add cache.hLars Hjemli2008-03-27
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 <hjemli@gmail.com>
hive to READMEJune McEnroe 2021-06-10Stop accumulating ISUPPORT tokens once MOTD startsJune McEnroe This avoids duplicating tokens when a client sends VERSION and the server responds with its 005s again. 2021-06-09Use seprintf for snip, removing strlcpynJune McEnroe 2021-06-09Use seprintf for reserializeJune McEnroe 2021-06-09Use seprintf for capListJune McEnroe 2021-06-09Add seprintfJune McEnroe Based on seprint(2) from Plan 9. I'm not sure if my return value exactly matches Plan 9's in the case of truncation. seprint(2) is described only as returning a pointer to the terminating '\0', but if it does so even in the case of truncation, it is awkward for the caller to detect. This implementation returns end in the truncation case, so that (ptr == end) indicates truncation. 2021-05-27Add pounce-notify to README 2.4June McEnroe 2021-05-27Fix ENVIRONMENT formatting in pounce-notify(1)June McEnroe 2021-05-27Add note about Libera.Chat SASL-only rangesJune McEnroe 2021-05-25Add QUIRKS fileJune McEnroe 2021-05-19Replace freenode with tilde.chatJune McEnroe 2021-05-04notify: Reword pounce-notify manualJune McEnroe 2021-05-02Clean up Makefiles, configure scriptsJune McEnroe Default MANDIR to ${PREFIX}/man since it turns out man-db includes /usr/local/man by default.
