* Only show first 80 characters of commit subject in log and summaryLars Hjemli2006-12-22
| | | | Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Show list of modified files in ui-commit.cLars Hjemli2006-12-17
| | | | | | | | Compare current commit with 1.parent, and for each affected file display current filemode, old filemode if changed, current filename and source filename if it was a copy/rename. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

* Add caching infrastructureLars Hjemli2006-12-10
| | | | | | | | | | | | | | | | | | | | | | 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>
* Import cgit prototype from git treeLars Hjemli2006-12-09
This enables basic cgit functionality, using libgit.a and xdiff/lib.a from git + a custom "git.h" + openssl for sha1 routines. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
