This works exactly as before but a little more correct and with the additions to be able to track kernel sources or whole source tree with a local revision system. Example output follows (uname -v) from my system being tracked locally with mercurial. FreeBSD 8.1-STABLE #0 r211092M 55:65408c40b051 Mon Aug 9 07:03:32 EDT 2010 jhell@ujump.dataix.net:/usr/obj/usr/src/sys/MITHOP Inspiration for making these changes came from mercurial, OpenSolaris and finally http://wiki.freebsd.org/LocalMercurial Following is a list of changes that I have made that I believe people that are involved with the source may find useful. 1 file changed, 55 insertions(+), 35 deletions(-) This allows a user: * That is using csup(1) or cvsup(1) to locally keep track of the whole source tree or just the kernel part of the tree using svn(1), hg(1) or git(1). * That is using svn(1) to checkout their source tree to use hg(1) or git(1) to keep track of the whole tree or the kernel part of the tree. http://svn.freebsd.org/base/ * That is using git(1) to checkout their source tree to use hg(1) to keep track of the whole tree or the kernel part of the tree. http://spoerlein.net/gitweb/ This checks for: * SCM roots in src/ or src/sys for .svn, .hg, & .git and acts accordingly if they exist while prioritizing using an SCM root in src/ before it uses src/sys/ * Then looks for acceptable binaries for svn(1), hg(1) git(1) within the select paths /usr/local/bin & then /usr/bin. The paths may change for svn(1) or git(1) & maybe mercurial if it ever becomes part of world. Currently I have set these to only look in /usr/local/bin. Cleanups: * Instead of using variables that shared the same name as their counterpart binaries to hold a revision number use more descriptive names like svnrev gitrev & hgrev for revisions. Use git svnversion & hg variables for their respective binaries. * Adjust the paths that are checked for binaries to be of only /usr/local/bin and /usr/bin. "/bin" is highly unlikely to hold svn(1), git(1) or hg(1). * Test for a SCM root in the source tree locations before we look for binaries. If these don't exist there is no need to know where svn or git are. * For git(1) always set work-tree and git-dir so there is no possibility to end up with a "-dirty" git(1) revision. * Remove extraneous "touch version" since the previous if statement already creates the file if its not found. * Inline the test for version file. >How-To-Repeat: >Fix: Attached patch. Should apply cleanly to head and stable/8 but was developed on stable/8 r211092.
