When HPA added Cygwin target, it ran just fine without NO_MMAP for him,
but recently we are getting reports that for some people things break
without it. For now, just suggest it in the Makefile without actually
updating the default.
the excessively verbose output of git fetch makes the result totally
unreadable. It's impossible to tell if it actually fetched anything new or
not, since the screen will fill up with an endless supply of
...
* committish: 9165ec17fde255a1770886189359897dbb541012
tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
* refs/tags/v0.99.7c: same as tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
...
and any new tags that got fetched will be totally hidden.
So add a new "--verbose" flag to "git fetch" to enable this verbose mode,
but make the default be quiet.
NOTE! The quiet mode will still report about new or changed heads, so if
you are really fetching a new head, you'll see something like this:
[torvalds@g5 git]$ git fetch --tags parent
Packing 6 objects
Unpacking 6 objects
100% (6/6) done
* refs/tags/v1.0rc2: storing tag 'v1.0rc2' of master.kernel.org:/pub/scm/git/git
* refs/tags/v1.0rc3: storing tag 'v1.0rc3' of master.kernel.org:/pub/scm/git/git
* refs/tags/v1.0rc1: storing tag 'v1.0rc1' of master.kernel.org:/pub/scm/git/git
which actually tells you something useful that isn't hidden by all the
useless crud that you already had.
Extensively tested (hey, for me, this _is_ extensive) by doing a
rm .git/refs/tags/v1.0rc*
and re-fetching with both --verbose and without.
NOTE! This means that if the fetch didn't actually fetch anything at all,
git fetch will be totally quiet. I think that's much better than being so
verbose that you can't even tell whether something was fetched or not, but
some people might prefer to get a "nothing to fetch" message in that case.

Now git-apply can grok binary replacement patches, give --binary
flag to git-am. As a safety measure, this is not by default
enabled, so that you do not let malicious e-mailed patch to
replace an arbitrary path with just a couple of lines (diff
index lines, the filename and string "Binary files "...) by
accident.
This allows people to use syntax like "last thursday" for the approxidate.
(Or, indeed, more complex "three thursdays ago", but I suspect that would
be pretty unusual).
NOTE! The parsing is strictly sequential, so if you do
"one day before last thursday"
it will _not_ do what you think it does. It will take the current time,
subtract one day, and then go back to the thursday before that. So to get
what you want, you'd have to write it the other way around:
"last thursday and one day before"
which is insane (it's usually the same as "last wednesday" _except_ if
today is Thursday, in which case "last wednesday" is yesterday, and "last
thursday and one day before" is eight days ago).
Similarly,
"last thursday one month ago"
will first go back to last thursday, and then go back one month from
there, not the other way around.
I doubt anybody would ever use insane dates like that, but I thought I'd
point out that the approxidate parsing is not exactly "standard English".
Side note 2: if you want to avoid spaces (because of quoting issues), you
can use any non-alphanumberic character instead. So
git log --since=2.days.ago
works without any quotes.

git's rev-parse.c function show_datestring presumes gnu date
Ok. This is the insane patch to do this.
It really isn't very careful, and the reason I call it "approxidate()"
will become obvious when you look at the code. It is very liberal in what
it accepts, to the point where sometimes the results may not make a whole
lot of sense.
It accepts "last week" as a date string, by virtue of "last" parsing as
the number 1, and it totally ignoring superfluous fluff like "ago", so
"last week" ends up being exactly the same thing as "1 week ago". Fine so
far.
It has strange side effects: "last december" will actually parse as "Dec
1", which actually _does_ turn out right, because it will then notice that
it's not December yet, so it will decide that you must be talking about a
date last year. So it actually gets it right, but it's kind of for the
"wrong" reasons.
It also accepts the numbers 1..10 in string format ("one" .. "ten"), so
you can do "ten weeks ago" or "ten hours ago" and it will do the right
thing.
But it will do some really strange thigns too: the string "this will last
forever", will not recognize anyting but "last", which is recognized as
"1", which since it doesn't understand anything else it will think is the
day of the month. So if you do
gitk --since="this will last forever"
the date will actually parse as the first day of the current month.
And it will parse the string "now" as "now", but only because it doesn't
understand it at all, and it makes everything relative to "now".
Similarly, it doesn't actually parse the "ago" or "from now", so "2 weeks
ago" is exactly the same as "2 weeks from now". It's the current date
minus 14 days.
But hey, it's probably better (and certainly faster) than depending on GNU
date. So now you can portably do things like
gitk --since="two weeks and three days ago"
git log --since="July 5"
git-whatchanged --since="10 hours ago"
git log --since="last october"
and it will actually do exactly what you thought it would do (I think). It
will count 17 days backwards, and it will do so even if you don't have GNU
date installed.
(I don't do "last monday" or similar yet, but I can extend it to that too
if people want).
It was kind of fun trying to write code that uses such totally relaxed
"understanding" of dates yet tries to get it right for the trivial cases.
The result should be mixed with a few strange preprocessor tricks, and be
submitted for the IOCCC ;)
Feel free to try it out, and see how many strange dates it gets right. Or
wrong.
And if you find some interesting (and valid - not "interesting" as in
"strange", but "interesting" as in "I'd be interested in actually doing
this) thing it gets wrong - usually by not understanding it and silently
just doing some strange things - please holler.
Now, as usual this certainly hasn't been getting a lot of testing. But my
code always works, no?
A new option, --full-index, is introduced to diff family. This
causes the full object name of pre- and post-images to appear on
the index line of patch formatted output, to be used in
conjunction with --allow-binary-replacement option of git-apply.
A new option, --allow-binary-replacement, is introduced.
When you feed a diff that records full SHA1 name of pre- and
post-image blob on its index line to git-apply with this option,
the post-image blob replaces the path if what you have in the
working tree matches the pre-image _and_ post-image blob is
already available in the object directory.
Later we _might_ want to enhance the diff output to also include
the full binary data of the post-image, to make this more
useful, but this is good enough for local rebasing application.
After failed patch application, you can manually apply the patch
(this includes resolving the conflicted merge after git-am falls
back to 3-way merge) and run git-update-index on necessary paths
to prepare the index file in a shape a successful patch
application should have produced. Then re-running git-am --resolved
would record the resulting index file along with the commit log
information taken from the patch e-mail.
Recently we fixed 'git-apply --stat' not to barf on a binary
differences. But it accidentally broke the error detection when
we actually attempt to apply them.
This commit fixes the problem and adds test cases.
For some reason I've done a "git grep" twice with no pattern, which is
really irritating, since it just grep everything. If I actually wanted
that, I could do "git grep ^" or something.
So add a "usage" message if the pattern is empty.

This patch provides a C implementation of the 'git' program and
introduces support for putting the git-* commands in a directory
of their own. It also saves some time on executing those commands
in a tight loop and it prints the currently available git commands
in a nicely formatted list.
The location of the GIT_EXEC_PATH (name discussion's closed, thank gods)
can be obtained by running
git --exec-path
which will hopefully give porcelainistas ample time to adapt their
heavy-duty loops to call the core programs directly and thus save
the extra fork() / execve() overhead, although that's not really
necessary any more.
The --exec-path value is prepended to $PATH, so the git-* programs
should Just Work without ever requiring any changes to how they call
other programs in the suite.
Some timing values for 10000 invocations of git-var >&/dev/null:
git.sh: 24.194s
git.c: 9.044s

The git-<tab><tab> behaviour can, along with the someday-to-be-deprecated
git-<command> form of invocation, be indefinitely retained by adding
the following line to one's .bash_profile or equivalent:
PATH=$PATH:$(git --exec-path)
Experimental libraries can be used by either setting the environment variable
GIT_EXEC_PATH, or by using
git --exec-path=/some/experimental/exec-path
Relative paths are properly grok'ed as exec-path values.

where gitweb was found to be using a lot of time and memory to
detect renames on huge commits. git-diff family takes -l<num>
flag, and if the number of paths that are rename destination
candidates (i.e. new paths with -M, or modified paths with -C)
are larger than that number, skips rename/copy detection even
when -M or -C is specified on the command line.
This commit makes the rename detection limit easier to use. You
can have:
[diff]
renamelimit = 30
in your .git/config file to specify the default rename detection
limit. You can override this from the command line; giving 0
means 'unlimited':
git diff -M -l0
We might want to change the default behaviour, when you do not
have the configuration, to limit it to say 20 paths or so. This
would also help the diffstat generation after a big 'git pull'.
Rework object refs tracking to reduce memory usage
Store pointers to referenced objects in a variable sized array instead
of linked list. This cuts down memory usage of utilities which use
object references; e.g., git-fsck-objects --full on the git.git
repository consumes about 2 MB of memory tracked by Massif instead of
7 MB before the change. Object refs are still the biggest consumer of
memory (57%), but the malloc overhead for a single block instead of a
linked list is substantially smaller.

Documentation: do not blindly run 'cat' .git/HEAD, or echo into it.
Many places in the documentation we still talked about reading
what commit is recorded in .git/HEAD or writing the new head
information into it, both assuming .git/HEAD is a symlink. That
is not necessarily so.
The current http-fetch is rather careless about fd leakage, causing
problems while fetching large repositories. This patch does not reserve

This fixes git-rev-list so that when there are multiple branches, we still
sort the heads in proper approximate date order even when sorting the
output topologically.
This makes things like
gitk --all -d
work sanely and show the branches in date order (where "date order" is
obviously modified by the paren-child dependency requirements of the
topological sort).
The trivial fix is to just build the "work" list in date order rather than
inserting the new work entries at the beginning.

merge-one-file: use empty- or common-base condintionally in two-stage merge.
If two sides added the same path completely different thing, it is
easier to see the merge pivoting on /dev/null. So check the size of
the common section we have found, and empty it if it is too small.
merge-one-file: use common as base, instead of emptiness.
Unlike the previous round that merged the path added differently
in each branches using emptiness as the base, compute a common
version and use it as input to 'merge' program.
This would show the resulting (still conflicting) file left in
the working tree as:
common file contents...
<<<<<< FILENAME
version from our branch...
======
version from their branch...
>>>>>> .merge_file_XXXXXX
more common file contents...
Merge ... /dev/null as base, instead of punting O==empty case
Instead of leaving the path unmerged in a case where each side
adds different version of the same path, attempt to merge it
with empty base and leave "our" version in the index file, just
like we do for the case in conflicting merge.
t1200: use --topo-order to keep the show-branch output stable.
Because a batch-oriented script creates many commits within a second
on a fast machine, show-branch output of the test results are unstable
without topo-order.
With the change in the previous round, we are guaranteed to come up
with the list of all relevant merge bases, but sometimes we do not
fully mark unintersting ones due to a horizon effect. Add a phase to
postprocess, so that we mark all ancestor of "interesting" commit.
This also changes the default ordering of shown commits back to
chronological order, and adds --topo-order flag to show them in
topological order.
This makes the merge-base computation resistant to the pathological
case discussed on the list earlier, by doing the same logic as
git-merge-base. As a side effect, it breaks the command's primary
function to list non-merge commit sequences, which needs to be fixed
separately.
Although it was shown that the "full contamination" was not really full
during the list discussion, the series improves things without incurring
extra parsing cost, and here is a test to check that.
