Since commit c699866 (parsing: clear query path before starting, 2017-02-19), we clear the "page" variable simply by calling cgit_parse_url() even if the URL is empty. This breaks a URL like: .../cgit?p=about which is generated when using the "root-readme" configuration option. This happens because "page" is set to "about" when parsing the query string before we handle the path (which is empty, but non-null). It turns out that this is not the only case which is broken, but specifying repository and page via query options has been broken since before the commit mentioned above, for example: .../cgit?r=git&p=log Fix both of these by allowing the previous state to persist if PATH_INFO is empty, falling back to the query parameters if no path has been requested.

cgit - CGI for Git
==================
This is an attempt to create a fast web interface for the Git SCM, using a
built-in cache to decrease server I/O pressure.
Installation
------------
Building cgit involves building a proper version of Git. How to do this
depends on how you obtained the cgit sources:
a) If you're working in a cloned cgit repository, you first need to
initialize and update the Git submodule:
$ git submodule init # register the Git submodule in .git/config
$ $EDITOR .git/config # if you want to specify a different url for git
$ git submodule update # clone/fetch and checkout correct git version
b) If you're building from a cgit tarball, you can download a proper git
version like this:
$ make get-git
When either a) or b) has been performed, you can build and install cgit like
this:
$ make
$ sudo make install
This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
can configure this location (and a few other things) by providing a `cgit.conf`
file (see the Makefile for details).
If you'd like to compile without Lua support, you may use:
$ make NO_LUA=1
And if you'd like to specify a Lua implementation, you may use:
$ make LUA_PKGCONFIG=lua5.1
If this is not specified, the Lua implementation will be auto-detected,
preferring LuaJIT if many are present. Acceptable values are generally "lua",
"luajit", "lua5.1", and "lua5.2".
Dependencies
------------
* libzip
* libcrypto (OpenSSL)
* libssl (OpenSSL)
* optional: luajit or lua, most reliably used when pkg-config is available
Apache configuration
--------------------
A new `Directory` section must probably be added for cgit, possibly something
like this:
<Directory "/var/www/htdocs/cgit/">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>
Runtime configuration
---------------------
The file `/etc/cgitrc` is read by cgit before handling a request. In addition
to runtime parameters, this file may also contain a list of repositories
displayed by cgit (see `cgitrc.5.txt` for further details).
The cache
---------
When cgit is invoked it looks for a cache file matching the request and
returns it to the client. If no such cache file exists (or if it has expired),
the content for the request is written into the proper cache file before the
file is returned.
If the cache file has expired but cgit is unable to obtain a lock for it, the
stale cache file is returned to the client. This is done to favour page
throughput over page freshness.
The generated content contains the complete response to the client, including
the HTTP headers `Modified` and `Expires`.
