Notes for util-linux-ng developers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
AUTOTOOLS:
* "./autogen.sh" generates all necessary files (run it after checkout from
git)
* "make mrproper" removes all generates files. You have to call autogen.sh
after mrproper.
* "make distclean" is subset of mrproper. It removes all unnecessary files,
but code is still possible recompile by "./configure; make"
* "make dist-gzip" (or -bzip2) creates tarball which is possible use without
autogen.sh
PATCHES:
* send your patches to the mailing list or to upstream maintainer
(see the AUTHORS file)
* diff -u
* don't include generated (autotools) stuff to your patches
* patches are delivered via email only. Downloading them from internet
servers is a pain.
* one patch per email, with the changelog in the body of the email.
* Subject: [PATCH] subsystem: description
* if someone else wrote the patch, they should be credited (and blamed) for it.
To communicate this, add a line:
From: John Doe <jdoe@wherever.com>
* add a Signed-off-by line:
Signed-off-by: Foo Bar <fb@wherever.com>
* there is a lot of really useful rules. Please, read:
The perfect patch
http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt
SCM (source code management):
git clone git://git.kernel.org/pub/scm/utils/util-linux-ng/util-linux-ng.git util-linux-ng
* maintenance branch(es)
- created for every <major>.<minor> release, branch name: v<major>.<minor>-mnt
* master branch
- the status of this branch is: "it works for me". It means useful
but not well tested patches.
- it's source for occasional snapshots
- for long-term development or invasive changes should be an active
development forked into a separate branch (topic branches) from the
tip of "master".
* A new tag object is created for:
- every release, tag name: v<version>
- every public snapshot, tag name: s<version>-YYYYMMDD
