2006-12-28Add generic support for search box in page headerLars Hjemli-2/+2
This adds the ability to show a search box in any pageheader with correct href and hidden form data, but does not enable the box on any pages. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2006-12-20Add basic diff viewLars Hjemli-0/+2
Finally, xdiff is used to show per-file diffs via commit view. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2006-12-16Allow relative paths for cgit_cache_rootLars Hjemli-0/+4
Make sure we chdir(2) back to the original getcwd(2) when a page has been generated. Also, if the cgit_cache_root do not exist, try to create it. This is a feature intended to ease testing/debugging. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2006-12-16Add argument parsing + switch for uncached operationLars Hjemli-3/+47
This adds support for the following options to cgit: --root=<path> --cache=<path> --nocache --query=<querystring> --repo=<reponame> --page=<pagename> --head=<branchname> --sha1=<sha1> --ofs=<number> On startup, /etc/cgitrc is parsed, followed by argument parsing and finally querystring parsing. If --nocache is specified (or set in /etc/gitrc), caching is disabled and cgit instead generates pages to stdout. The combined effect of these two changes makes testing/debugging a lot less painfull.

2006-12-11Don't truncate valid cachefilesLars Hjemli-4/+10
An embarrassing thinko in cgit_check_cache() would truncate valid cachefiles in the following situation: 1) process A notices a missing/expired cachefile 2) process B gets scheduled, locks, fills and unlocks the cachefile 3) process A gets scheduled, locks the cachefile, notices that the cachefile now exist/is not expired anymore, and continues to overwrite it with an empty lockfile. Thanks to Linus for noticing (again). Signed-off-by: Lars Hjemli <hjemli@gmail.com>

2006-12-11Avoid infinite loops in caching layerLars Hjemli-1/+8
Add a global variable, cgit_max_lock_attemps, to avoid the possibility of infinite loops when failing to acquire a lockfile. This could happen on broken setups or under crazy server load. Incidentally, this also fixes a lurking bug in cache_lock() where an uninitialized returnvalue was used. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
2006-12-11Fix cache algorithm loopholeLars Hjemli-9/+9
This closes the door for unneccessary calls to cgit_fill_cache(). Noticed by Linus. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

2006-12-10Add caching infrastructureLars Hjemli-15/+102
This enables internal caching of page output. Page requests are split into four groups: 1) repo listing (front page) 2) repo summary 3) repo pages w/symbolic references in query string 4) repo pages w/constant sha1's in query string Each group has a TTL specified in minutes. When a page is requested, a cached filename is stat(2)'ed and st_mtime is compared to time(2). If TTL has expired (or the file didn't exist), the cached file is regenerated. When generating a cached file, locking is used to avoid parallell processing of the request. If multiple processes tries to aquire the same lock, the ones who fail to get the lock serves the (expired) cached file. If the cached file don't exist, the process instead calls sched_yield(2) before restarting the request processing. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
