* filter: don't use dlsym unnecessarily
 John Keeping
2015-08-13-36/+420c4d767
| | | | | | | We only need to hook write() if Lua filter's are in use. If support has been disabled, remove the dependency on dlsym(). Signed-off-by: John Keeping <john@keeping.me.uk>
* ui-tree: use "sane" isgraph()
 John Keeping
2015-08-13-1/+37105a78
| | | | | | | | | | | | | | | | | | Git's git-compat-util.h defines a "sane ctype" that does not use locale information and works with signed chars, but it does not include isgraph() so we have included ctype.h ourselves. However, this means we have to include a system header before git-compat-util.h which may lead to the system defining some macros (e.g. _FILE_OFFSET_BITS on Solaris) before git-compat-util.h redefines them with a different value. We cannot include ctype.h after git-compat-util.h because we have defined many of its functions as macros which causes a stream of compilation errors. Defining our own "sane" isgraph() using Git's sane isprint() and isspace() avoids all of these problems. Signed-off-by: John Keeping <john@keeping.me.uk>

* cache.c: fix header order
 John Keeping
2015-08-13-3/+343620cf
| | | | | | | | git-compat-util.h may define values that affect how system headers are interpreted, so move sys/sendfile.h after cgit.h (which includes git-compat-util.h). Signed-off-by: John Keeping <john@keeping.me.uk>
* configfile.c: don't include system headers directly
 John Keeping
2015-08-13-2/+1f2e8ca8
| | | | | | | | | git-compat-util.h may define various values that affect the interpretation of system headers. In most places we include cgit.h first, which pulls in git-compat-util.h, but this file does not depend on anything else in CGit, so use git-compat-util.h directly.

* Remove redundant includes

* tests: allow shell to be overridden
 John Keeping
2015-08-13-1/+52ef4ede
| | | | | | | | | | | On some systems (e.g. Solaris), /bin/sh is not a POSIX shell. Git already provides suitable overrides in its config.mak.uname file and we provide cgit.conf to allow the user to further change this. The code for this is taken from Git's t/Makefile, meaning that we now invoke the tests in the same way that Git does. Signed-off-by: John Keeping <john@keeping.me.uk>

* log: allow users to follow a file
 John Keeping
2015-08-12-18/+19430304d8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach the "log" UI to behave in the same way as "git log --follow", when given a suitable instruction by the user. The default behaviour remains to show the log without following renames, but the follow behaviour can be activated by following a link in the page header. Follow is not the default because outputting merges in follow mode is tricky ("git log --follow" will not show merges). We also disable the graph in follow mode because the commit graph is not simplified so we end up with frequent gaps in the graph and many lines that do not connect with any commits we're actually showing. We also teach the "diff" and "commit" UIs to respect the follow flag on URLs, causing the single-file version of these UIs to detect renames. This feature is needed only for commits that rename the path we're interested in. For commits before the file has been renamed (i.e. that appear later in the log list) we change the file path in the links from the log to point to the old name; this means that links to commits always limit by the path known to that commit. If we didn't do this we would need to walk down the log diff'ing every commit whenever we want to show a commit. The drawback is that the "Log" link in the top bar of such a page links to the log limited by the old name, so it will only show pre-rename commits. I consider this a reasonable trade-off since the "Back" button still works and the log matches the path displayed in the top bar. Since following renames requires running diff on every commit we consider, I've added a knob to the configuration file to globally enable/disable this feature. Note that we may consider a large number of commits the revision walking machinery no longer performs any path limitation so we have to examine every commit until we find a page full of commits that affect the target path or something related to it.

* contrib/hooks: add sample post-receive hook using agefile
 John Keeping
2015-08-12-0/+19121e653
| | | | | | | | | | | | One of the most frequent questions on the mailing list relates to the idle time in the repository list. The answer to this is to use the "agefile" feature to calculate the time of the last change whenever the repository receives changes. Add a sample post-receive hook in a new "contrib" directory so that we can just point people at the repository in the future. Signed-off-by: John Keeping <john@keeping.me.uk>

 John Keeping
2015-03-03-1/+14db9a70b
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CGit is killed while it holds a lock on a cache slot (for example because it is taking too long to generate a page), the lock file will be left in place. This prevents any future attempt to use the same slot since it will fail to exclusively create the lock file. Since CGit is the only program that should be manipulating lock files, we can use advisory locking to detect whether another process is actually using the lock file or if it is now stale. I have confirmed that this works on Linux by setting a short TTL in a custom cgitrc and running the following with CGit patched to print a message to stderr if the fcntl(2) fails: $ export CGIT_CONFIG=$PWD/cgitrc $ export QUERY_STRING=url=cgit/tree/ui-shared.c $ ./cgit | grep -v -e '^<div class=.footer.>' \ -e '^Last-Modified: ' \ -e ^'Expires: ' >expect $ seq 50000 | dd bs=8192 | parallel -j200 "diff -u expect <(./cgit | grep -v -e '^<div class=.footer.>' \ -e '^Last-Modified: ' \ -e ^'Expires: ') || echo BAD" This printed the fail message several times without ever printing "BAD".
