Makefile: use git-describe to mark the git version. Note: with this commit, the GIT maintainer workflow must change. GIT-VERSION-GEN is now the file to munge when the default version needs to be changed, not Makefile. The tag needs to be pushed into the repository to build the official tarball and binary package beforehand. Signed-off-by: Junio C Hamano <junkio@cox.net>

GIT-VERSION-GEN: adjust for ancient git When an ancient "git" that does not understand "describe" command is on the $PATH, "git describe" emitted a Usage message without exiting non-zero status (which is a mistake we cannot fix retroactively). Catch this case to make sure we do not try using phoney multi-line string as a version number. Signed-off-by: Junio C Hamano <junkio@cox.net>

GIT-VERSION-FILE: check ./version first. When somebody else extracts git tarball inside a larger project, 'git describe' would reported the version number of that upper level project. Sometimes, using the consistent versioning across subdirectories of a larger project is useful, but it may not always be the right thing to do. This changes the script to check ./vertion file first, and then fall back to "git describe". This way, by default, tarball distribution will get our own version. If the upper level wants to use consistent versioning across its subdirectories, its Makefile can overwrite ./version file to force whatever version number they want to give us before descending into us.

GIT-VERSION-GEN: squelch unneeded error from "cat version" Now this is really a corner case, but if you have the git source tree from somewhere other than the official tarball, you do not have version file. And if git-describe does not work for you (maybe you do not have git yet), we spilled an error message from "cat version". Signed-off-by: Junio C Hamano <junkio@cox.net>

GIT-VERSION-GEN: do not force abbreviation length used by 'describe' The default version name for a Git binary is computed by running "git describe" on the commit the binary is made out of, basing on a tag whose name matches "v[0-9]*", e.g. v2.11.0-rc2-2-g7f1dc9. In the very early days, with 9b88fcef7d ("Makefile: use git-describe to mark the git version.", 2005-12-27), we used "--abbrev=4" to get absolute minimum number of abbreviated commit object name. This was later changed to match the default minimum of 7 with bf505158d0 ("Git 1.7.10.1", 2012-05-01). These days, the "default minimum" scales automatically depending on the size of the repository, and there is no point in specifying a particular abbreviation length; all we wanted since Git 1.7.10.1 days was to get "something reasonable we would use by default". Just drop "--abbrev=<number>" from the invocation of "git describe" and let the command pick what it thinks is appropriate, taking the end user's configuration and the repository contents into account.

GIT-VERSION-GEN: mark the version 'dirty' only if there are modified files We used to mark the version string with '-dirty' if the cache was not up to date, but the only thing we want to know is if the binaries are built from modified source. Refresh the cache to avoid false dirtyness. Christian Jaeger noticed this issue while building under fakeroot environment (without -u) that lies about the file ownership data.
