* segfault fix on some bogus requestsEric Wong2012-03-181-2/+2
| | | | | | | | | ctx.qry.head can be NULL in some cases due to bad requests by weird bots. I managed to reproduce with: PATH_INFO=/repo.git/shop.php QUERY_STRING=id= Signed-off-by: Eric Wong <normalperson@yhbt.net>
* use correct type for sizeofJamie Couture2012-03-181-1/+1
| | | | | | | | | **L would have worked well too. Depending on the distribution sizeof *L may return 8 instead of 4. **L is preferable, but since we don't expect this datatype to change very often, sizeof int is less subtle and easier to understand.

* ui-ssdiff.c: correct length check for LCS tableEric Wong2012-01-081-4/+2
| | | | | | | Each individual string may be too long for its respective dimension of the LCS table. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* Fix segmentation fault in empty repositoryJohn Keeping2012-01-031-1/+1
| | | | | | | | | | | When a repository is empty, the ATOM feed link is written in the header, but this involves formatting ctx->qry.head which is NULL in this case. With glibc, vsnprintf formats "%s" with a NULL input as "(null)" but on Solaris this results in a segmentation fault. Since we don't have a meaningful head for the atom feed in an empty repository, it's simplest not to write out the link element at all. Signed-off-by: John Keeping <john@metanate.com>
* Makefile: fetch git tarballs from http://hjemli.net/git/git/Lars Hjemli2012-01-031-1/+1
| | | | | | | The git tarballs are currently not available from kernel.org, so for now the makefile will download autogenerated tarballs from cgit. Signed-off-by: Lars Hjemli <hjemli@gmail.com>

* Fix diff mode switching when side-by-side-diffs=1Tim Chen2012-01-033-2/+3
| | | | | | | When side-by-side-diffs=1 was set in cgitrc, specyfing 'ss=0' in the query- string would not switch to unified diffs. This patch fixes the issue by introducing a separate variable to track the occurrence of "ss" in the querystring.
* ui-log.c: do not show remote heads if enable-remote-branches=0Georg Müller2012-01-031-0/+3
| | | | | If remote branches are not enabled, the branches are still listed in the log view. This patch removes them if enable-remote-branches=0.
* Add sort parameter to pager of repo listTobias Grimm2012-01-033-13/+19
| | | | | | When the repolist is paged, the page-links are missing the sort parameter, causing the initial page to be custom sorted, but any clicked page will then be with the default sort order again.
* ui-ssdiff: move LCS table away from the stackJamie Couture2012-01-032-2/+43
| | | | | | | | | | | Printing deferred line changes for files containing long lines would cause a segfault. - limit LCS table size: 128x128. - move LCS table to global context: avoid allocating/freeing memory for every deferred line change. Signed-off-by: Jamie Couture <jamie.couture@gmail.com>
* Fix potential XSS vulnerability in rename hintLukas Fleischer2011-07-221-4/+6
| | | | | | | | | The file name displayed in the rename hint should be escaped to avoid XSS. Note that this vulnerability is only applicable when an attacker has gained push access to the repository. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Remove dead initialization in cgit_parse_commit()Lukas Fleischer2011-07-221-1/+1

* tests: fix failures when CDPATH is setFerry Huberts2011-07-211-0/+1
| | | | | | | | | | Some tests would otherwise fail because commands such as cd trash/repos/foo && git rev-list --reverse HEAD | head -1 would return 2 lines instead of 1: the 'cd' command also prints the path when CDPATH is set.

* cgit.c: improve error message when git repo cannot be accessedLars Hjemli2011-06-181-1/+5
| | | | | | | | | | | | | The current 'Not a git repository' error message is not very helpful, since it doesn't state the cause of the problem. This patch uses errno to provide a hint of the underlying problem. It would have been even better to give the exact cause (e.g. for ENOENT it would be nice to know which file/directory is missing), but that would require reimplementing setup_git_directory_gently() which seems a bit overkill.

* ui-plain.c: fix html and links generated by print_dir() and print_dir_entry()Lars Hjemli2011-06-121-19/+46
| | | | | | | | | | | This patch fixes the following issues: * the base argument usually isn't zero-terminated, so printing base without considering baselen will usually generate random garbage * when the current url represents a directory but doesn't end in a slash, relative urls would be incorrect * using unescaped paths allows XSS Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* scan-tree.c: avoid memory leakJamie Couture2011-06-061-0/+2

* fix virtual-root if script-name is ""Mark Lodato2011-05-231-1/+4
| | | | | | | | | | | In d0cb841 (Avoid trailing slash in virtual-root), virtual-root was set from script-name using trim_end(). However, if script-name was the empty string (""), which happens when cgit is used to serve the root path on a domain (/), trim_end() returns NULL and cgit acts like virtual-root is not available. Now, set virtual-root to "" in this case, which fixes this bug. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* ui-repolist.c: do not return random/stale data from read_agefileLars Hjemli2011-05-231-1/+1
| | | | | | | | | | | When git/date.c:parse_date() cannot parse its input it returns -1. But read_agefile() checks if the result is different from zero, essentialy returning random data from the date buffer when parsing fails. This patch fixes the issue by verifying that the result from parse_date() is positive. Noticed-by: Julius Plenz <plenz@cis.fu-berlin.de> Signed-off-by: Lars Hjemli <hjemli@gmail.com>
* Avoid null pointer dereference in cgit_print_diff().Lukas Fleischer2011-05-231-2/+6
| | | | | | | | | | When calling cgit_print_diff() with a bad new_rev and a NULL old_rev, checking for new_rev's parent commit will result in a null pointer dereference.

* fix two encoding bugsJulius Plenz2011-03-261-9/+15
| | | | | | | | | | | | | | reencode() takes three arguments in the order (txt, from, to), opposed to reencode_string, which will, like iconv, handle the arguments with from and to swapped. Fix that (this makes reencode more intuitive). If src and dst encoding are equivalent, don't do any encoding. If no special encoding parameter is found within the commit, assume UTF-8 and explicitly convert to PAGE_ENCODING. The change to reencode() mentioned above avoids re-encoding a UTF-8 string to UTF-8, for example. Signed-off-by: Julius Plenz <plenz@cis.fu-berlin.de> Signed-off-by: Lars Hjemli <hjemli@gmail.com>

| | | | | | | | | | | | | | | | | | | | When setting virtual-root from cgitrc, care is taken to avoid trailing slashes. But when no virtual-root setting is specified, SCRIPT_FILE from the web server is used without similar checks.
