This removes the separate "formats" for name and name-with-zero-
termination.
It also removes the difference between HUMAN and MACHINE formats, and
they both become DIFF_FORMAT_RAW, with the difference being just in the
line and inter-filename termination.
It also makes the code easier to understand.

... and make git-diff-files use it too. This all _should_ make the
diffcore-pathspec.c phase unnecessary, since the diff'ers now all do the
path matching early interally.
|
|
This brings all the same pathspec optimizations that git-diff-tree does
to git-diff-cache.
|
|
The reason I say "start using" is that we really should also limit the
index checking by name - now we limit the tree object accesses by name,
but we still check the whole index.
Still, this should help.
|
|
The same way the other pathspecs work. Also fix missing success return
from the matching - not that anything actually uses this yet ;)
|
|
The same way "git-diff-tree" can limit its output to just a set of matches,
we can read in just a partial tree for comparison purposes.
|
|
The symlink case had never worked, and the file case was broken by the
O_EXCL change because the error return changed from EISDIR to EEXIST.
Fix both problems by just moving the test for an existing directory to a
more logical place.
|
|
Give a sane error rather than just silently claiming no diffs when
you're not at the top-level directory.
|
|
It's too dangerous not to. We need to follow alternate object
directories etc, or we might say something is unreachable just because
we didn't look it up completely.

This splits push-pull related commands into a separate
category. I think a bigger overhaul of the main index is
needed, but have not got around to it. Help is welcome.

While adding the documentation for these two commands, I noticed
that the name of the program on the other end (git-upload-pack)
is already almost configurable but git-clone-pack lacked command
line parameter parsing to actually use anything but default, so
I introduced --exec= like other remote commands while I was at it.

Now that we have something called tag object, and a notion of
"tags" stored in .git/refs/tags/ directory, the word "tagname"
has become misleading in the usage string. The documentation

With the socket case, the input and output fd's might end up being the same,
so we want to dup the other before we close either of them.

Useful for pulling stuff off a dedicated server. Instead of connecting
with ssh or just starting a local pipeline, we connect over TCP to the
other side and try to see if there's a git server listening.
Of course, since I haven't written the git server yet, that will never
happen. But the server really just needs to listen on a port, and
execute a "git-upload-pack" when somebody connects.
(It should read one packet-line, which should be of the format
"git-upload-pack directoryname\n"
and eventually we migth have other commands the server might accept).
|
|
We should always have unlinked any old ones before, but this just makes
sure that we never over-write any old file.
A quick "grep" now shows that all the core tools that open files for
writing use O_EXCL, ie we never overwrite an existing file in place.
|
|
We write them under another name and rename them to their destination,
so that if something bad happens in the middle, we won't have caused any
bigger harm.
Also, this makes the writing be NFS "intr" safe, and as a side effects
makes sure that if the target is hardlinked (or symlinked) we will have
broken the link.

Porcelain layers often want to find only names of changed files,
and even with diff-raw output format they end up having to pick
out only the filename. Support --name-only (and --name-only-z
for xargs -0 and cpio -0 users that want to treat filenames with
embedded newlines sanely) flag to help them.

We'll want to use it for the tagging too.
|
|
This is part of breaking up the tag ID patch by Eric Biederman.
|
|
There's a few generated files that we left behind.
|
|
That way we avoid any confusion with "GNU Interactive Tools", and it's
more descriptive anyway (the rpm documentation talks about how git is
split into a "core" part and an "SCM" part, this makes it clear that
this is the core one).
|
|
You can use it as
git branch <branchname> [start-point]
and it creates a new branch of name <branchname>. If a starting point
is specified, that will be where the branch is created, otherwise it
will be created at the current HEAD.
The sequence
git branch xyz abc
git checkout xyz
can also be written as
git checkout -b xyz abc
as per the previous commit.
|
|
In particular, if we check out something that isn't an old branch, it
now requires a new branch-name to check the thing out into.
So, for example:
git checkout -b my-branch v2.6.12
will create the new branch "my-branch", and start it at v2.6.12, while
git checkout master
will just switch back to the master branch.
Of course, if you want to create a new branch "my-branch" and _not_
check it out, you could have done so with just
git-rev-parse v2.6.12^0 > .git/refs/heads/my-branch
which I think I will codify as "git branch".
|
|
We still need to create a new branch if it didn't refer to an existing
branch, otherwise our HEAD will continue to point to something totally
different than what we just checked out.
I'll need to think about it. Maybe only do it with "-f" and force it to
the "master" branch?
|
|
This sounds nonsensical, but it's useful to make sure that the result is
a commit.
For example, "git-rev-parse v2.6.12" will return the _tag_ object for
v2.6.12, but "git-rev-parse v2.6.12^0" will return the _commit_ object
associated with that tag (and v2.6.12^1 will return the first parent).
Also, since the "parent" code will actually parse the commit, this,
together with the "--verify" flag, will verify not only that the result
is a single SHA1, but will also have verified that it's a proper commit
that we can see.

Cut-and-paste dup noticed by Junio. It's not even harmless, since a
match also causes that match to be invalidated, so this made it
impossible to update an existing branch by name.
I'd only tested the case of "ref doesn't exist at all on the other end",
which worked fine.

This reverses the order of object lookup, to check pack index first and
then go to the filesystem to find .git/objects/??/ hierarchy.
When most of the objects are packed, this saves quite many stat() calls
and negative dcache entries; while the price this approach has to pay is
negligible, even when most of the objects are outside pack, because
checking pack index file is quite cheap.

When we allow a tag object in place of a commit object, we only
dereferenced the given tag once, which causes a tag that points at a tag
that points at a commit to be rejected. Instead, dereference tag
repeatedly until we get a non-tag.
This patch makes change to two functions:
- commit.c::lookup_commit_reference() is used by merge-base,
rev-tree and rev-parse to convert user supplied SHA1 to that of
a commit.
- rev-list uses its own get_commit_reference() to do the same.
Dereferencing tags this way helps both of these uses.

The location alt_odb[j].name[0..] is filled with ??/?{38} to form a sha1
filename to try, but I was too lazy to allocate a copy, so while
fsck_object_dir() is running for the directory, the filenames ??/?{38}
are filled after NUL (usually and always the location should have '/'),
making them "not found".
This should fix it.

We used to print the index of the object we unpacked, not how many we
had unpacked. Which caused slightly confusing progress reports like
100% (2/3) done
rather than the more obvious "3/3" for 100% ;)
