2015-08-14snapshot: don't reimplement cgit_print_error_page()John Keeping1-17/+4
cgit_print_error_page() has the advantage that it sets a suitable HTTP status code for the response. Note that setting "mimetype" is redundant here since it cannot have changed since being initialized in cgit.c::prepare_context(), so we do not need to worry that cgit_print_error_page() does not set it.

2015-08-14snapshot: use cgit_print_error_page() for HTTP status codesJohn Keeping1-2/+4
This is a bugfix as well as an improvement to the HTTP status code handling since previously we would not print HTTP headers on any of these code paths. Signed-off-by: John Keeping <john@keeping.me.uk>

2015-08-14cgit: use cgit_print_error_page() where appropriateJohn Keeping1-20/+7
These are more-or-less one-to-one translations but in the final hunk we gain an HTTP error code where we used to send "200 OK", which is an improvement. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-14ui-shared: add cgit_print_error_page() functionJohn Keeping2-0/+16

2015-08-14ui-patch: make sure to send http headersChristian Hesse1-0/+4
Requesting a text/plain patch with bad commit id made cgit send text without proper http headers. This results in "500 Internal Server Error" with "Premature end of script headers" in server logs. So print http headers before error message and return. Signed-off-by: Christian Hesse <mail@eworm.de> Reviewed-by: John Keeping <john@keeping.me.uk>
2015-08-13Makefile: make "git/config.mak.uname" inclusion optionalJohn Keeping1-1/+1
If we haven't got a "git" directory, it should still be possible to run "make get-git", so we cannot include this file unconditionally. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-13ui-shared: show full date in tooltip if longer ago than max_relativeJohn Keeping1-0/+4
Commit caed6cb (ui-shared: show absolute time in tooltip for relative dates, 2014-12-20) added a toolip when we show a relative time. However, in some cases we show a short date (that is, the date but not the time) if an event was sufficiently far in the past and that commit did not update that case to add the same tooltip.

2015-08-13ui-tree: use "sane" isgraph()John Keeping2-1/+3
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>
2015-08-13cgit.h: move stdbool.h from ui-shared.hJohn Keeping2-2/+2
Follow the Git policy of including system headers in only one place. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-13cache.c: fix header orderJohn Keeping1-3/+3
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>
2015-08-13configfile.c: don't include system headers directlyJohn Keeping1-2/+1
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. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-13Remove redundant includesJohn Keeping6-16/+0
These are all included in git-compat-util.h (when necessary), which we include in cgit.h. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-13Makefile: include Git's config.mak.unameJohn Keeping1-0/+1
This pulls in the correct value of $(INSTALL) on a wide variety of systems. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-13tests: allow shell to be overriddenJohn Keeping1-1/+5
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>

2015-08-12log: allow users to follow a fileJohn Keeping10-18/+194
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.

2015-08-12contrib/hooks: add sample post-receive hook using agefileJohn Keeping1-0/+19
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>

2015-03-09html: avoid using a plain integer as a NULL pointerJohn Keeping1-22/+32
Sparse complains about this table because we use the integer zero as the NULL pointer.
