1 | Cache algorithm |
| |
2 | =============== |
| |
3 | |
| |
4 | Cgit normally returns cached pages when invoked. If there is no cache file, or |
| |
5 | the cache file has expired, it is regenerated. Finally, the cache file is |
| |
6 | printed on stdout. |
| |
7 | |
| |
8 | When it is decided that a cache file needs to be regenerated, an attempt is |
| |
9 | made to create a corresponding lockfile. If this fails, the process gives up |
| |
10 | and uses the expired cache file instead. |
| |
11 | |
| |
12 | When there is no cache file for a request, an attempt is made to create a |
| |
13 | corresponding lockfile. If this fails, the process calls sched_yield(2) before |
| |
14 | restarting the request handling. |
| |
15 | |
| |
16 | In pseudocode: |
| |
17 | |
| |
18 | name = generate_cache_name(request); |
| |
19 | top: |
| |
20 | if (!exists(name)) { |
| |
21 | if (lock_cache(name)) { |
| |
22 | generate_cache(request, name); |
| |
23 | unlock_cache(name); |
| |
24 | } else { |
| |
25 | sched_yield(); |
| |
26 | goto top; |
| |
27 | } |
| |
28 | } else if (expired(name)) { |
| |
29 | if (lock_cache(name)) { |
| |
30 | generate_cache(request, name); |
| |
31 | unlock_cache(name); |
| |
32 | } |
| |
33 | } |
| |
34 | print_file(name); |
| |
35 | |
| |
36 | |
| |
37 | The following options can be set in /etc/cgitrc to control cache behaviour: |
| |
38 | cache-root: root directory for cache files |
| |
39 | cache-root-ttl: TTL for the repo listing page |
| |
40 | cache-repo-ttl: TTL for any repos summary page |
| |
41 | cache-dynamic-ttl: TTL for pages with symbolic references (not SHA1) |
| |
42 | cache-static-ttl: TTL for pages with sha1 references |
| |
43 | |
| |
44 | TTL is specified in minutes, -1 meaning "infinite caching". |
| |
45 | |
| |
46 | |
| |
47 | Naming of cache files |
| |
48 | --------------------- |
| |
49 | Repository listing: <cachedir>/index.html |
| |
50 | Repository summary: <cachedir>/<repo>/index.html |
| |
51 | Repository subpage: <cachedir>/<repo>/<page>/<querystring>.html |
| |
52 | |
| |
53 | The corresponding lock files have a ".lock" suffix. |
| |
