2014-12-13filter: fix libravatar email-filter https issueChristian Hesse1-1/+2
Serving cgit via https and getting avatar via http gives error messages about untrusted content. This decides whether or not to use https link by looking at the environment variable HTTPS, which is set in CGI.

This also gives us some CSRF protection. Note that we make use of the hmac to protect the redirect value. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2014-01-16auth: add basic authentication filter frameworkJason A. Donenfeld1-0/+225
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 <Jason@zx2c4.com>

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 <Jason@zx2c4.com>

2014-01-14filter: add page source to email filterJason A. Donenfeld2-1/+3
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 <Jason@zx2c4.com>

2014-01-13filters: Improved syntax-highlighting.pyStefan Tatschner1-19/+33
- Switched back to python2 according to a problem in pygments with python3. With the next release of pygments this problem should be fixed. Issue see here: https://bitbucket.org/birkenfeld/pygments-main/issue/901/problems-with-python3 - Just read the stdin, decode it to utf-8 and ignore unknown signs. This ensures that even destroyed files do not cause any errors in the filter. - Improved language guessing: -> At first use guess_lexer_for_filename for a better detection of the used programming languages (even mixed cases will be detected, e.g. php + html). -> If nothing was found look if there is a shebang and use guess_lexer. -> As default/fallback choose TextLexer.

2012-10-27syntax-highlighting.sh: Fix command injection.Jason A. Donenfeld1-2/+2
By not quoting the argument, an attacker with the ability to add files to the repository could pass arbitrary arguments to the highlight command, in particular, the --plug-in argument which can lead to arbitrary command execution. This patch adds simple argument quoting.
2012-10-09syntax-highlight: when the file has no extension, assume textFerry Huberts1-1/+4
There are 2 situations: 1- empty extension: assuming text is better than highlight producing no output because of a missing argument. 2- no extension at all: assuming text is better than setting the extension to the filename, which is what now happens.

This reverts commit f50be7fda0a7ab57009169dd5905fcbab8eb5166. An update with the latest highlight landed in EPEL. This new version doesn't have the --force bug, so the workaround can now be removed. Signed-off-by: Ferry Huberts <ferry.huberts@pelagic.nl>

This allows for putting descriptions closer to their expressions. It should also make it clearer how to apply an expression conditionally.
2009-11-19syntax highlighting for all formats supported by "highlight"Georg Lukas1-17/+12
The highlight tool can be given any of the supported file extensions as its -S parameter. This patch replaces the case-switch by extracting the extension from the supplied file name and passing it to highlight. However, this requires a shell supporting the ${var##pattern} syntax, like dash or bash. Unknown extensions cause a fall-back to plain text using the --force switch. Error messages are redirected to /dev/null. A special case maps Makefile and Makefile.* to the "mk" extension. The total overhead is reduced by calling "exec highlight". No forks are needed during script execution. Signed-off-by: Georg Lukas <georg@op-co.de>
