Add a cache-snapshot-ttl configuration variable

2014-02-20T18:56:44Z

This can be used to specify the TTL for snapshots. Snapshots are usually static and do not ever change. On the other hand, tarball generation is CPU intensive. One use case of this setting (apart from increasing the lifetime of snapshot cache slots) is caching of snapshots while disabling the cache for static/dynamic HTML pages (by setting TTL to zero for everything except for snapshot requests).

auth: add basic authentication filter framework

2014-01-16T01:28:12Z

This leverages the new lua support. See filters/simple-authentication.lua for explaination of how this works. There is also additional documentation in cgitrc.5.txt. Though this is a cookie-based approach, cgit's caching mechanism is preserved for authenticated pages. Very plugable and extendable depending on user needs. The sample script uses an HMAC-SHA1 based cookie to store the currently logged in user, with an expiration date. Signed-off-by: Jason A. Donenfeld

filter: basic write hooking infrastructure

2014-01-14T01:00:07Z

Filters can now call hook_write and unhook_write if they want to redirect writing to stdout to a different function. This saves us from potential file descriptor pipes and other less efficient mechanisms. We do this instead of replacing the call in html_raw because some places stdlib's printf functions are used (ui-patch or within git itself), which has its own internal buffering, which makes it difficult to interlace our function calls. So, we dlsym libc's write and then override it in the link stage. While we're at it, we move considerations of argument count into the generic new filter handler. Signed-off-by: Jason A. Donenfeld

filter: allow for cleanup hook for filter types

2014-01-14T01:00:07Z

At some point, we're going to want to do lazy deallocation of filters. For example, if we implement lua, we'll want to load the lua runtime once for each filter, even if that filter is called many times. Similarly, for persistent exec filters, we'll want to load it once, despite many open_filter and close_filter calls, and only reap the child process at the end of the cgit process. For this reason, we add here a cleanup function that is called at the end of cgit's main(). Signed-off-by: Jason A. Donenfeld

filter: add interface layer

2014-01-14T01:00:07Z

Change the existing cgit_{open,close,fprintf}_filter functions to delegate to filter-specific implementations accessed via function pointers on the cgit_filter object. We treat the "exec" filter type slightly specially here by putting its structure definition in the header file and providing an "init" function to set up the function pointers. This is required so that the ui-snapshot.c code that applies a compression filter can continue to use the filter interface to do so. Signed-off-by: John Keeping

filter: add fprintf_filter function

2014-01-14T01:00:07Z

This stops the code in cgit.c::print_repo needing to inspect the cgit_filter structure, meaning that we can abstract out different filter types that will have different fields that need to be printed. Signed-off-by: John Keeping

filter: pass extra arguments via cgit_open_filter

2014-01-12T19:20:20Z

This avoids poking into the filter data structure at various points in the code. We rely on the fact that the number of arguments is fixed based on the filter type (set in cgit_new_filter) and that the call sites all know which filter type they're using. Signed-off-by: John Keeping

filter: split filter functions into their own file

2014-01-10T16:45:43Z

A first step for more interesting things. Signed-off-by: Jason A. Donenfeld

filter: make exit status local

2014-01-10T16:45:43Z

It's only used in one place, and not useful to have around since close_filter will die() if exit_status isn't what it expects, anyway. So this is best as just a local variable instead of as part of the struct. Signed-off-by: Jason A. Donenfeld
