Yesterday I’ve upgraded my development machines from Fedora 17 to Fedora
18. Although it went well, my [Symfony](http://symfony.com/) projects stopped
working with a message like this:

    RuntimeException: Command "/usr/bin/grep --fixed-strings --directories=recurse --devices=skip --files-with-matches --with-filename --color=never --include=*.php 'JMS\DiExtraBundle\Annotation'

After getting through my logs and such, I’ve finally found out that the new
SELinux policy is causing the trouble together with git. Eventually, my
`.git/logs` directory is tagged as `unconfined_u:object_r:httpd_log_t:s0`.
`httpd_log_t` type is not readable by the `system_u:system_r:httpd_t:s0` user,
which makes `/usr/bin/grep` throw an access denied error. To fix this, I needed
to do

    semanage fcontext -a -t httpd_sys_content_t '/var/www(/.*)?/\.git/logs(/.*)?'

as root. This makes `.git` directories readable for the httpd process, thus,
for `grep`. The optimal solution would be to tell `GrepPatternFinder` to ignore
version control stuff, so the `httpd` process would have no access to them at
all. Also, in production, removing the `.git` or `.svn` directories could be a
good idea.
