git-sh-setup: move the repository check to a core program.
Any core commands that use setup_git_directory() now check if
given GIT_DIR is really a valid repository, so the same check in
git-sh-setup can use it without reimplementing it in shell.
This commit changes git-sh-setup to use git-var command for
that, although any other commands would do.
Note that we export GIT_DIR explicitly when calling git-var;
without it, the caller of this script would use GIT_DIR that we
return (which is to assume ./.git unless the caller has it
elsewhere) while git-var would go up to find a .git directory in
our parent directories, which would be checking a different
directory from what our callers will be using.
setup_git_directory: make sure GIT_DIR is a valid repository.
setup_git_directory() always trusted what the user told where
GIT_DIR was, and assumed that is a valid .git/ directory. This
commit changes it to at least do the same level validation as
is_toplevel_directory() does -- has refs/, has objects/ unless
GIT_OBJECT_DIRECTORY is set, and has valid HEAD symlink or
symref.
Now all the users of this script detect its exit status and die,
complaining that it is outside git repository. So move the code
that dies from all callers to git-sh-setup script.
There is no reason to use git-sh-setup from git-ls-remote.
git-parse-remote can help the caller to use .git/remotes
shortcut if it is run inside a git repository, but can still be
useful outside a git repositoryas long as the caller does not
use any shortcut. Use "git-rev-parse --git-dir" to figure out
where the GIT_DIR is, instead of using git-sh-setup.
This also makes "git-ls-remote origin" to work from inside a
subdirectory of a git managed repository as a side effect.
git-update-index --index-info can almost be usable to read from ls-tree
output to update the index (and not the working tree file) to HEAD commit,
but not quite. It was designed to read from git-apply --index-info
output, and does not want " blob " in ls-tree output. Accept that as well.
This lets us update "git-checkout <ent> <path>" that used to filter the
extra " blob " string out. Noted by Luben.
Revert always should explain why, so make --edit the default,
unless stdin is not a terminal. If you really don't want to say
anything, you can say "git-revert --no-edit $commit", or if you
are really sick, you could also say "git-revert $commit </dev/null".
But please don't.
You can also say "git-cherry-pick --edit $commit". Not editting
the commit log message is the default for cherry-pick.
I think all commit operations should allow editing of the message (ie we
should do this for merges too), but that's _particularly_ true of doing a
"git revert".
We should always explain why we needed to revert something.
This patch adds a "-e" or "--edit" flag to "git revert", although I
actually suspect it should be on by default (and we should have a
"--no-edit" flag to disable it, probably together with an automatic
disable if stdin isn't a terminal).

git-pull invoked merge with recursive as the default strategy
for some time now; match it in the git-merge itself. Also avoid
listing more than one strategy on default because we have only
one strategy that can resolve an octopus and we are already

modifications.

In a corrupt repository, git-repack produces a pack that does not

This builds on top of the git-proxy mechanism Paul Collins did,
and updates its configuration mechanism.
* GIT_PROXY_COMMAND environment variable is used as the
catch-all fallback, as in the original. This has not
changed.
* Renames proxy configuration variables to core.gitproxy; this
has become a multi-value variable per list discussion, most
notably from suggestion by Linus.
[core]
;# matches www.kernel.org as well
gitproxy = netcatter for kernel.org
gitproxy = netscatter for sample.xz
gitproxy = none for mydomain.xz
gitproxy = netcatter-default
The values are command names, followed by an optional " for "
and domainname; the first tail-match of the domainname
determines which proxy command is used. An entry without "
for " matches any domain and can be used as the default.
The command name "none" is special -- it tells the mechanism
not to use any proxy command and use the native git://
connection.
Here is an updated patch that first looks for GIT_PROXY_COMMAND
in the environment and then git.proxycommand in the repository's
configuration file. I have left the calling convention the same
argv[1] is the host and argv[2] is the port.
I've taken the hostname parsing verbatim from git_tcp_connect(),
so it should now support an explicit port number and whatever
that business with the square brackets is. (Should I move this
to a helper function?)
Regarding internal vs. external hosts, the proxy command can
simply run netcat locally to internal hosts, so perhaps that is
sufficient.
tutorial: setting up a tree for subsystem maintainers
The "copying over packs" step is to prevent the objects
available in upstream repository to get expanted in the
subsystem maintainer tree, and is still valid if the upstream
repository do not live on the same machine. But if they are on
the same machine using objects/info/alternates is cleaner.
rename detection with -M100 means "exact renames only".
When the user is interested in pure renames, there is no point
doing the similarity scores. This changes the score argument
parsing to special case -M100 (otherwise, it is a precision
scaled value 0 <= v < 1 and would mean 0.1, not 1.0 --- if you
do mean 0.1, you can say -M1), and optimizes the diffcore_rename
transformation to only look at pure renames in that case.
format-patch: fix two-argument special case, and make it easier to pick single commits
Luben Tuikov noticed that sometimes being able to say
'git-format-patch <commit>' to format the change a single commit
introduces relative to its parent is handy.
This patch does not support that directly, but it makes sense to
interpret a single argument "rev" to mean "rev^1..rev".
With this, the backward compatibility syntaxes still apply:
- "format-patch master" means "format-patch master..HEAD"
- "format-patch origin master" means "format-patch origin..master"
- "format-patch origin.." means "format-patch origin..HEAD"
But "format-patch a b c d e" formats the changes these five
commits introduce relative to their respective parents. Earlier
it rejected these arguments not in "one..two" form.
Make sure heads/foo and tags/foo do not confuse things.
When both heads/foo and tags/foo exist, get_sha1_basic("foo")
picked up the tag without complaining, which is quite confusing.
Make sure we require unambiguous form, "heads/foo" or "tags/foo"
in such cases.
We wanted --strict to mean "do not DWIM", but the code required to
see absolute path. daemon does its own path verification and chdirs
to the verified repository, so enter_repo() called from upload-pack
will always enter ".". Requiring absolute path does not make any sense.
This basically translates the man-page from 'git-developerish' to plain
english, adding some almost-sample output from git-status so users can
recognize what will happen.
Also mention explicitly that --mixed updates the index, while --soft
doesn't. I understood the old text to mean "--mixed is exactly like
--soft, but verbose".

Add functions git_config_set() and git_config_set_multivar()
The function git_config_set() does exactly what you think it does.
Given a key (in the form "core.filemode") and a value, it sets the
key to the value. Example:
git_config_set("core.filemode", "true");
The function git_config_set_multivar() is meant for setting variables which
can have several values for the same key. Example:
The third argument of the function is a POSIX extended regex which has to
match the value. If there is no key/value pair with a matching value, a new
key/value pair is added.
These commands are also capable of unsetting (deleting) entries:

gitk switched to use git-diff-tree with one argument in gettreediffs and
getblobdiffs. git-diff-tree with one argument outputs commit ID in from

which is useless there.
This patch makes git use the newly added -no-commit-id option for

Rewrite rebase to use git-format-patch piped to git-am.
The current rebase implementation finds commits in our tree but
not in the upstream tree using git-cherry, and tries to apply
them using git-cherry-pick (i.e. always use 3-way) one by one.
Which is fine, but when some of the changes do not apply
cleanly, it punts, and punts badly.
Suppose you have commits A-B-C-D-E since you forked from the
upstream and submitted the changes for inclusion. You fetch
from upstream head U and find that B has been picked up. You
run git-rebase to update your branch, which tries to apply
changes contained in A-C-D-E, in this order, but replaying of C
fails, because the upstream got changes that touch the same area
from elsewhere.
Now what?
It notes that fact, and goes ahead to apply D and E, and at the
very end tells you to deal with C by hand. Even if you somehow
managed to replay C on top of the result, you would now end up
with ...-B-...-U-A-D-E-C.
Breaking the order between B and others was the conscious
decision made by the upstream, so we would not worry about it,
and even if it were worrisome, it is too late for us to fix now.
What D and E do may well depend on having C applied before them,
which is a problem for us.
This rewrites rebase to use git-format-patch piped to git-am,
and when the patch does not apply, have git-am fall back on
3-way merge. The updated diff/patch pair knows how to apply
trivial binary patches as long as the pre- and post-images are
locally available, so this should work on a repository with
binary files as well.
The primary benefit of this change is that it makes rebase
easier to use when some of the changes do not replay cleanly.
In the "unapplicable patch in the middle" case, this "rebase"
works like this:
- A series of patches in e-mail form is created that records
what A-C-D-E do, and is fed to git-am. This is stored in
.dotest/ directory, just like the case you tried to apply
them from your mailbox. Your branch is rewound to the tip of
upstream U, and the original head is kept in .git/ORIG_HEAD,
so you could "git reset --hard ORIG_HEAD" in case the end
result is really messy.
- Patch A applies cleanly. This could either be a clean patch
application on top of rewound head (i.e. same as upstream
head), or git-am might have internally fell back on 3-way
(i.e. it would have done the same thing as git-cherry-pick).
In either case, a rebased commit A is made on top of U.
- Patch C does not apply. git-am stops here, with conflicts to
be resolved in the working tree. Yet-to-be-applied D and E
are still kept in .dotest/ directory at this point. What the
user does is exactly the same as fixing up unapplicable patch
when running git-am:
- Resolve conflict just like any merge conflicts.
- "git am --resolved --3way" to continue applying the patches.
- This applies the fixed-up patch so by definition it had
better apply. "git am" knows the patch after the fixed-up
one is D and then E; it applies them, and you will get the
changes from A-C-D-E commits on top of U, in this order.
I've been using this without noticing any problem, and as people
may know I do a lot of rebases.
A new usage, 'git-branch -f branch [start]', resets the branch head at
start (or current head). Should be considered a dangerous operation,
but if you are like me to keep rewinding branches it is handy.

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.
