This matches the use of the variables with the same names in autotools, reducing the potential for user surprise.

2013-02-25Merge branch 'jn/less-reconfigure'Libravatar Junio C Hamano1-6/+8
A change made on v1.8.1.x maintenance track had a nasty regression to break the build when autoconf is used. * jn/less-reconfigure: Makefile: avoid infinite loop on configure.ac change
2013-02-20Makefile: avoid infinite loop on configure.ac changeLibravatar Jeff King1-6/+8
If you are using autoconf and change the configure.ac, the Makefile will notice that config.status is older than configure.ac, and will attempt to rebuild and re-run the configure script to pick up your changes. The first step in doing so is to run "make configure". Unfortunately, this tries to include config.mak.autogen, which depends on config.status, which depends on configure.ac; so we must rebuild config.status. Which leads to us running "make configure", and so on. It's easy to demonstrate with: make configure ./configure touch configure.ac make We can break this cycle by not re-invoking make to build "configure", and instead just putting its rules inline into our config.status rebuild procedure. We can avoid a copy by factoring the rules into a make variable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-02-08Makefile: make script-related rules usable from subdirectoriesLibravatar Matthieu Moy1-3/+32
Git's Makefile provides a few nice features for script build and installation (substitute the first line with the right path, hardcode the path to Git library, ...). The Makefile already knows how to process files outside the toplevel directory with e.g. make SCRIPT_PERL=path/to/file.perl path/to/file but we can make it simpler for callers by exposing build, install and clean rules as .PHONY targets.

2013-02-01Makefile: explicitly set target name for autogenerated dependenciesLibravatar Jonathan Nieder1-2/+3
"gcc -MF depfile -MMD -MP -c -o path/to/file.o" produces a makefile snippet named "depfile" describing what files are needed to build the target given by "-o". When ccache versions before v3.0pre0~187 (Fix handling of the -MD and -MDD options, 2009-11-01) run, they execute gcc -MF depfile -MMD -MP -E instead to get the final content for hashing. Notice that the "-c -o" combination is replaced by "-E". The result is a target name without a leading path. Thus when building git with such versions of ccache with COMPUTE_HEADER_DEPENDENCIES enabled, the generated makefile snippets define dependencies for the wrong target: $ make builtin/add.o GIT_VERSION = 1.7.8.rc3 * new build flags or prefix CC builtin/add.o $ head -1 builtin/.depend/add.o.d add.o: builtin/add.c cache.h git-compat-util.h compat/bswap.h strbuf.h \ After a change in a header file, object files in a subdirectory are not automatically rebuilt by "make": $ touch cache.h $ make builtin/add.o $ Luckily we can prevent trouble by explicitly supplying the name of the target to ccache and gcc, using the -MQ option. Do so.

2013-01-03Makefile: hoist uname autodetection to config.mak.unameLibravatar Jeff King1-542/+1
Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

2013-01-02build: do not automatically reconfigure unless configure.ac changedLibravatar Jonathan Nieder1-2/+8
Starting with v1.7.12-rc0~4^2 (build: reconfigure automatically if configure.ac changes, 2012-07-19), "config.status --recheck" is automatically run every time the "configure" script changes. In particular, that means the configuration procedure repeats whenever the version number changes (since the configure script changes to support "./configure --version" and "./configure --help"), making bisecting painfully slow. The intent was to make the reconfiguration process only trigger for changes to configure.ac's logic. Tweak the Makefile rule to match that intent by depending on configure.ac instead of configure.

Earlier we allowed platforms that lack <sys/param.h> not to include the header file from git-compat-util.h; we have included this header file since the early days back when we used MAXPATHLEN (which we no longer use) and also depended on it slurping ULONG_MAX (which we get by including stdint.h or inttypes.h these days). It turns out that we can compile our modern codebase just file without including it on many platforms (so far, Fedora, Debian, Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are reported to be OK). Let's stop including it by default, and on platforms that need it to be included, leave "make NEEDS_SYS_PARAM_H=YesPlease" as an escape hatch and ask them to report to us, so that we can find out about the real dependency and fix it in a more platform agnostic way.

This is nice except when you run make another time setting a different PYTHON_PATH, because, as the python scripts have already been created, make finds nothing to do. The goal of this patch is to detect when the PYTHON_PATH changes and to create the python scripts again when this happens. To do that we use the same trick that is done to track other variables like prefix, flags, tcl/tk path and shell path. We update a GIT-PYTHON-VARS file with the PYTHON_PATH and check if it changed.
