emacs: Use makefile-gmake-mode in Makefile*s Use `makefile-gmake-mode' instead of `makefile-mode' because the former also highlights ifdef et al. while the latter does not. "./Makefile.global" and one "Makefile.local" failed to specify any major mode at all but doing so is necessary because Emacs does not automatically figure out that these are Makefiles (of any flavor).
Use https instead of http where possible Many of the external links found in the notmuch source can be resolved using https instead of http. This changeset addresses as many as i could find, without touching the e-mail corpus or expected outputs found in tests.
build: add dataclean It turns out to be inconvenient to delete the downloaded datafiles with distclean, so I propose a new target which does that instead. The closest conventional target is 'maintainer-clean'; the difference here is that having the original source tarball is not enough to reconstruct these files.
build: don't overwrite DISTCLEAN in performance-test This might have worked once for some fixed order of including makefiles, but it is clearly wrong now.
perf: Clean corpus and caches in distclean, not clean Previously, we cleaned the downloaded performance corpus and the cached indexes on 'make clean'. This seems heavy-handed, since these take a long time to download, unpack, and index. They also aren't make targets to begin with. Move cleaning these to 'make distclean'. This isn't exactly the right meaning of "distclean", but it's closer.
build: fix out-of-tree builds Support for out-of-tree builds was added in commit 3e4a9d60a9419621b08c647a306843d76c47c2cb Author: Carl Worth <cworth@cworth.org> Date: Wed Mar 9 15:02:42 2011 -0800 build: Add support for non-source-directory builds. and broken in commit 7beeb8c88a014ecbc53d8241f10683b3c4c16228 Author: David Bremner <bremner@debian.org> Date: Sat Nov 17 12:28:15 2012 -0400 test: initial performance testing infrastructure Fix the build breakage. Out-of-tree 'make test' has been broken since earlier than the above, and remains broken, as does out-of-tree perf test, but at least the build now works.
perf-test: initial version of memory test infrastructure. The idea is run some code under valgrind --leak-check=full and report a summary, leaving the user to peruse the log file if they want. We go to some lengths to preserve the log files from accidental overwriting; the full corpus takes about 3 hours to run under valgrind on my machine. The naming of the log directories may be slightly controversial; in the unlikely event of two runs in less than a second, the log will be overwritten. A previous version with mktemp+timestamp was dismissed as overkill; just mktemp alone does not sort nicely. One new test is included, to check notmuch new for memory leaks.
perf-test: rename current tests as "time tests" This is almost entirely renaming files, except for updating a few references to those file names, and changing the makefile target. A new set of memory tests will be run separately because they take much longer.
perf-test: add caching of xapian database The caching and uncaching seem to be necessarily manual, as timing the initial notmuch new is one of our goals with this suite.
perf-test: cache unpacked corpus Unpacking is not really the expensive step (compared to the initial notmuch new), but this is a pre-requisite to caching the database.
test: initial performance testing infrastructure This is not near as fancy as as the unit tests, on the theory that the code should typically be crashing when performance tuning. Nonetheless, there is plenty of room for improvement. Several more of the pieces of the test infrastructure (e.g. the option parsing) could be factored out into test/test-lib-common.sh
