It's a one-liner, but it's useful as documentation if nothing else.

The documentation of the test harness still refer to old
numbering and also contains an obvious typo.
Also "make test" should be run after making sure we have built
all binaries, since test is designed to test the newly built
ones.

It used to be that diff-tree needed helper support to parse its
raw output to generate diffs, but these days git-diff-* family
produces the same output and the helper is not tied to diff-tree
anymore. Drop "tree" from its name.
This commit is done separately to record just the rename and no
file content changes. The changes in the renamed files are recorded
in the next commit.

Mark Allen had trouble with building GIT on his Darwin and
posted a patch to link with -lcrypto instead of -lssl on Darwin.
Later Daniel Barkalow suggested to change it for everybody who
uses openssl, because the relevant functionality is in -lcrypto
not in -lssl, and the current linking happens to work only
because -lssl pulls in -lcrypto.

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.

Separate out the merge resolve from the actual getting of the
data. Also, update the resolve phase to take advantage of the
fact that we don't need to do the commit->tree object lookup
by hand, since all the actors involved happily just act on a
commit object these days.

A new command, git-write-blob, is introduced. This registers
the contents of any file on the filesystem as a blob in the
object database and reports its SHA1 to the standard output.
To implement it, the patch promotes index_fd() from a static
function in update-cache.c to extern and moves it to a library
source, sha1_file.c.
This command is used to update git-merge-one-file-script so that
it does not smudge the work tree.

I said:
- Stop attempting to be compatible with cg-patch, and drop
(mode:XXXXXX) bits from the diff.
- Do keep the /dev/null change for created and deleted case.
- No "Index:" line, no "Mode change:" line, anywhere in the
output. Anything that wants the mode bits and sha1 hash can
do things from GIT_EXTERNAL_DIFF mechanism. Maybe document
suggested usage better.
This adds an example script git-apply-patch-script, that can be
used as the GIT_EXTERNAL_DIFF to apply changes between two trees
directly on the current work tree, like this:
GIT_EXTERNAL_DIFF=git-apply-patch-script git-diff-tree -p <tree> <tree>

This date parser turns line-noise into a date. Cool.
|
|
As suggested by Nicolas Pitre
|
|
...since everything out there is either strange (libc mktime has issues
with timezones) or introduces unnecessary dependencies for people (libcurl).
This goes back to the old date parsing, but moves it out into a file of
its own, and does the "struct tm" to "seconds since epoch" handling by
hand.
I grepped through the tz-database and it seems there's one "country"
left that has non-60-minute DST: Lord Howe Island. All others dropped
that before 1970.
|
|
This switches git-commit-tree to using curl_getdate() for the
AUTHOR_DATE, and thus fixes the problem with "mktime()" parsing dates in
the local timezone. It also ends up being more permissive about the
format of the date.

This also regularizes the make. The source files themselves don't get
the "git-" prefix, because that's just inconvenient. So instead we just
make the rule that "git-xxxx" depends on "xxxx.c", and do that for
all the core programs (ie the old "git-mktag.c" got renamed to just
"mktag.c" to match everything else).
And "show-diff" got renamed to "git-diff-files" while at it, since
that's what it really should be to match the other git-diff-xxx cases.

This is an improved version of tar-tree, a streaming archive creator for
GIT. The major added feature is blocking; all write(2) calls now have a
size of 10240, just as GNU tar (and tape drives) likes them. The
buffering overhead does not seem to degrade performance because most
files in the repositories I tested this with are smaller than 10KB, so
we need fewer system calls.
File names are still restricted to 500 bytes and the archive format
currently only allows for files up to 8GB. Both restrictions can be
lifted if need be with more pax extended headers.
The archive format used is the pax interchange format, i.e. POSIX tar
format. It can be read by (and created with) GNU tar. If I read the
specs correctly tar-tree should now be standards compliant (modulo
bugs).
Because it streams the archive (think ls-tree merged with cat-file),
tar-tree doesn't need to create any temporary files. That makes it
quite fast.
It accepts tree IDs and commit IDs as first parameter. In the latter
case tar-tree tries to get the commit date out of the committer line.
Else all files in the archive are time-stamped with the current time.
An optional second parameter is used as a path prefix for all files in
the archive. Example:
$ tar-tree a2755a80f40e5794ddc20e00f781af9d6320fafb \

This patch introduces a new program, diff-tree-helper. It reads
output from diff-cache and diff-tree, and produces a patch file.
The diff format customization can be done the same way the
show-diff uses; the same external diff interface introduced by
the previous patch to drive diff from show-diff is used so this
is not surprising.
It is used like the following examples:
$ diff-cache --cached -z <tree> | diff-tree-helper -z -R paths...
$ diff-tree -r -z <tree1> <tree2> | diff-tree-helper -z paths...
- As usual, the use of the -z flag is recommended in the script
to pass NUL-terminated filenames through the pipe between
commands.
- The -R flag is used to generate reverse diff. It does not
matter for diff-tree case, but it is sometimes useful to get
a patch in the desired direction out of diff-cache.
- The paths parameters are used to restrict the paths that
appears in the output. Again this is useful to use with
diff-cache, which, unlike diff-tree, does not take such paths
restriction parameters.

With this patch, the non-core'ish part of show-diff command that
invokes an external "diff" comand to obtain patches is split
into a separate file. The next patch will introduce a new
command, diff-tree-helper, which uses this common diff interface
to format diff-tree and diff-cache output into a patch form.

You use "git-mktag" to create them, and fsck-cache knows how to parse them.

This is probably what you'd want to see for "git log".

This patch adds three similar and related programs. http-pull downloads
objects from an HTTP server; rpull downloads objects by using ssh and
rpush on the other side; and rpush uploads objects by using ssh and rpull
on the other side.
The algorithm should be sufficient to make the network throughput required
depend only on how much content is new, not at all on how much content the
repository contains.
The combination should enable people to have remote repositories by way of
ssh login for authenticated users and HTTP for anonymous access.

This one includes the Mozilla SHA1 implementation sent in by Edgar Toernig.
It's dual-licenced under MPL-1.1 or GPL, so in the context of git, we
obviously use the GPL version.
Side note: the Mozilla SHA1 implementation is about twice as fast as the
default openssl one on my G5, but the default openssl one has optimized
x86 assembly language on x86. So choose wisely.

Yeah, my Makefiles are always a total disaster. Better this than autotools
or some horror like that, though.

Do the usage and error reporting in "usage.c", and the sha1 file
accesses in "sha1_file.c".
Small, nice, easily separated parts. Good.
|
|
This introduces the concept of git "library" objects that
the real programs use, and makes it easier to add such things
to a "libgit.a".
This will also make it trivial to split the current "read-cache.o"
into more aptly named pieces (it does a lot more than just read
the index file).

This was a real git merge with conflicts. I'll commit the scripts I used

The question of "best" commit can probably be tweaked almost arbitrarily.

It's there in the history if somebody wants to resurrect it, but it
