auth: have cgit calculate login address

2014-01-16T22:21:54Z

This way we're sure to use virtual root, or any other strangeness encountered. Signed-off-by: Jason A. Donenfeld

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: allow returning exit code from filter

2014-01-14T17:09:52Z

Filters can now indicate a status back to cgit by means of the exit code for exec, or the return value from close for Lua. Signed-off-by: Jason A. Donenfeld

filter: add page source to email filter

2014-01-14T01:00:07Z

Since the email filter is called from lots of places, the script might benefit from knowing the origin. That way it can modify its contents and/or size depending. Signed-off-by: Jason A. Donenfeld

filter: return on null filter from open and close

2014-01-14T01:00:07Z

So that we don't have to include the if(filter) open_filter(filter) block everywhere, we introduce the guard in the function itself. This should simplify quite a bit of code. 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
