# Define MOZILLA_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
# on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
# choice) has very fast version optimized for i586.
#
# Define NO_OPENSSL environment variable if you do not have OpenSSL. You will
# miss out git-rev-list --merge-order. This also implies MOZILLA_SHA1.
#
# Define NO_CURL if you do not have curl installed. git-http-pull is not
# built, and you cannot use http:// and https:// transports.
#
# Define NO_STRCASESTR if you don't have strcasestr.
#
# Define PPC_SHA1 environment variable when running make to make use of
# a bundled SHA1 routine optimized for PowerPC.
#
# Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
#
# Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
#
# Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
# Patrick Mauritz).
#
# Define NO_GETDOMAINNAME if your library lack it (SunOS, Patrick Mauritz).
#
# Define COLLISION_CHECK below if you believe that SHA1's
# 1461501637330902918203684832716283019655932542976 hashes do not give you
# sufficient guarantee that no collisions between objects will ever happen.
# DEFINES += -DCOLLISION_CHECK
# Define USE_NSEC below if you want git to care about sub-second file mtimes
# and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
# it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
# randomly break unless your underlying filesystem supports those sub-second
# times (my ext3 doesn't).
# DEFINES += -DUSE_NSEC
# Define USE_STDEV below if you want git to care about the underlying device
# change being considered an inode change from the update-cache perspective.

Multi-backend merge driver. The new command 'git merge' takes the current head and one or more remote heads, with the commit log message for the automated case. If the heads being merged are simple fast-forwards, it acts the same way as the current 'git resolve'. Otherwise, it tries different merge strategies and takes the result from the one that succeeded auto-merging, if there is any. If no merge strategy succeeds auto-merging, their results are evaluated for number of paths needed for hand resolving, and the one with the least number of such paths is left in the working tree. The user is asked to resolve them by hand and make a commit manually. The calling convention from the 'git merge' driver to merge strategy programs is very simple: - A strategy program is to be called 'git-merge-<strategy>'. - They take input of this form: <common1> <common2> ... '--' <head> <remote1> <remote2>... That is, one or more the common ancestors, double dash, the current head, and one or more remote heads being merged into the current branch. - Before a strategy program is called, the working tree is matched to the current <head>. - The strategy program exits with status code 0 when it successfully auto-merges the given heads. It should do update-cache for all the merged paths when it does so -- the index file will be used to record the merge result as a commit by the driver. - The strategy program exits with status code 1 when it leaves conflicts behind. It should do update-cache for all the merged paths that it successfully auto-merged, and leave the cache entry in the index file as the same as <head> for paths it could not auto-merge, and leave its best-effort result with conflict markers in the working tree when it does so. - The strategy program exists with status code other than 0 or 1 if it does not handle the given merge at all. As examples, this commit comes with merge strategies based on 'git resolve' and 'git octopus'. Signed-off-by: Junio C Hamano <junkio@cox.net>

Rename environment variables. H. Peter Anvin mentioned that using SHA1_whatever as an environment variable name is not nice and we should instead use names starting with "GIT_" prefix to avoid conflicts. Here is what this patch does: * Renames the following environment variables: New name Old Name GIT_AUTHOR_DATE AUTHOR_DATE GIT_AUTHOR_EMAIL AUTHOR_EMAIL GIT_AUTHOR_NAME AUTHOR_NAME GIT_COMMITTER_EMAIL COMMIT_AUTHOR_EMAIL GIT_COMMITTER_NAME COMMIT_AUTHOR_NAME GIT_ALTERNATE_OBJECT_DIRECTORIES SHA1_FILE_DIRECTORIES GIT_OBJECT_DIRECTORY SHA1_FILE_DIRECTORY * Introduces a compatibility macro, gitenv(), which does an getenv() and if it fails calls gitenv_bc(), which in turn picks up the value from old name while giving a warning about using an old name. * Changes all users of the environment variable to fetch environment variable with the new name using gitenv(). * Updates the documentation and scripts shipped with Linus GIT distribution. The transition plan is as follows: * We will keep the backward compatibility list used by gitenv() for now, so the current scripts and user environments continue to work as before. The users will get warnings when they have old name but not new name in their environment to the stderr. * The Porcelain layers should start using new names. However, just in case it ends up calling old Plumbing layer implementation, they should also export old names, taking values from the corresponding new names, during the transition period. * After a transition period, we would drop the compatibility support and drop gitenv(). Revert the callers to directly call getenv() but keep using the new names. The last part is probably optional and the transition duration needs to be set to a reasonable value.
