Make git-send-pack exit with error when some refs couldn't be pushed out
In case some refs couldn't be pushed out due to an error (mostly the
not-a-proper-subset error), make git-send-pack exit with non-zero status
after the push is over (that is, it still tries to push out the rest
of the refs).

Although "git-merge" is advertised as the end-user level command
(instead of being a "git-pull" backend), it was not prepared to
take tag objects that point at commits and barfed when fed one.
Sanitize the input while we validate them, for which we already
have a loop.
git-clone: tell the user a bit more about clone-pack failure.
When clone-pack has trouble with the remote, it dies unfriendly
"EOF" error message. We cannot tell the reason why it failed
from the local end; it could be that the repository did not
exist, or configured not to serve over git-daemon, or a network
failure. At least, saying clone-pack failed makes it a bit more
meaningful.
I am not convinced yet that removing the newly created directory
is the right thing to do, so this commit leaves the new
directory behind.
The initial section of tutorial was too heavy on internal
workings for the first-time readers, so rewrite the introductory
section of git(7) to start with "not learning core git commands"
section and refer them to README to grasp the basic concepts,
then Everyday to give overview with task/role oriented examples
for minimum set of commands, and finally the tutorial.
Also add to existing note in the tutorial that many too
technical descriptions can be skipped by a casual reader.
I initially started to review the tutorial, with the objective
of ripping out the detailed technical information altogether,
but I found that the level of details in the initial couple of
sections that talk about refs and the object database in a
hands-on fashion was about rigth, and left all of them there. I
feel that reading about fsck-index and repack is too abstract
without being aware of these directories and files.
Delta computation with an empty blob used to punt and returned NULL.
This commit allows creation with empty blob; all combination of
empty->empty, empty->something, and something->empty are allowed.
This adds a couple of tests to cover the following renaming
merge cases:
- one side renames and the other side does not, with and without
content conflicts.
- both side rename to the same path, with and without content
conflicts.
The test setup also prepares a case in which both side rename to
different destination, but currently the code collapses these
destination paths and removes the original path, which may be
wrong. The outcome of this case is not checked by the tests in
this round.
Fredrik points out there is a useful wrapper runProgram() used
everywhere that we can use to feed input into subprocess. Use
it to catch errors from the subprocess; it is a good cleanup as
well.
merge-recursive: leave unmerged entries in the index.
This does two things.
- When one branch renamed and the other branch did not, the
resulting half-merged file in the working tree used to swap
branches around and showed as if renaming side was "ours".
This was confusing and inconsistent (even though the conflict
markers were marked with branch names, it was not a good
enough excuse). This changes the order of arguments to
mergeFile in such a case to make sure we always see "our"
change between <<< and ===, and "their" change between ===
and >>>.
- When both branches renamed to the same path, and when one
branch renamed and the other branch did not, we attempt
mergeFile. When this automerge conflicted, we used to
collapse the index. Now we use update-index --index-info
to inject higher stage entries to leave the index in unmerged
state for these two cases.
What this still does _not_ do is to inject unmerged state into
the index when the structural changes conflict. I have not
thought things through what to do in each case yet, but the
cases this commit cover are the most common ones, so this would
be a good start.
People seem to be getting test failure from t6021 not becuase
git is faulty but because they forgot to install "merge". Check
this and other trivial pilot errors in the first test.

git-prune: never lose objects reachable from our refs.
Explicit <head> arguments to git-prune replaces, instead of
extends, the list of heads used for reachability analysis by
fsck-objects. By giving a subset of heads by mistake, objects
reachable only from other heads can be removed, resulting in a
corrupted repository.
This commit stops replacing the list of heads, and makes the
command line arguments to add to them instead for safety.
This is a companion patch to e23eff8be92a2a2cb66b53deef020063cff285ed
commit. The same logic, the same rationale that a comparison
function that returns an int should not just compute a ptrdiff_t
and return it.
Not replacing but always including our own refs may be more
desirable (and unarguably much safer), but at the same time I
have a suspicion that that might be forbidding a useful usage I
haven't thought of, so...

gitk: Work around Tcl's non-standard names for encodings
This uses a table of encoding names and aliases distilled from
http://www.iana.org/assignments/character-sets plus some heuristics
to convert standard encoding names to ones that Tcl recognizes.
update-index: allow --index-info to add higher stages.
The new merge world order tells the merge strategies to leave
the cache unmerged and store the automerge result in the working
tree if automerge is not clean. This was done for the resolve
strategy and recursive strategy when no rename is involved, but
recording a conflicting merge in the rename case could not
easily be done by the recursive strategy.
This commit adds a new input format, in addition to the exsting
two, to "update-index --index-info".
(1) mode SP sha1 TAB path
The first format is what "git-apply --index-info"
reports, and used to reconstruct a partial tree
that is used for phony merge base tree when falling
back on 3-way merge.
(2) mode SP type SP sha1 TAB path
The second format is to stuff git-ls-tree output
into the index file.
(3) mode SP sha1 SP stage TAB path
This format is to put higher order stages into the
index file and matches git-ls-files --stage output.
To place a higher stage entry to the index, the path should
first be removed by feeding a mode=0 entry for the path, and
then feeding necessary input lines in the (3) format.
The first line of the input feeds 0 as the mode to remove the
path; the SHA1 does not matter as long as it is well formatted.
Then the second and third line feeds stage 1 and stage 2 entries
for that path. After the above, we would end up with this:
On AIX, there is no -n option to the system's echo. Instead,
it needs the '\c' control character. We could replace
echo -n "foo"
with
echo -e "foo\c"
but printf is recommended by most man pages. Tested on AIX
5.3, Solaris 8, and Debian.
[jc: futureproofed two instances that uses variable with '%s'
so later feeding different messages would not break things too
easily; others are emitting literal so whoever changes the
literal ought to notice more easily so they are safe.]

Added an AIX clause in the Makefile; that clause likely
will be wrong for any AIX pre-5.2, but I can only test
on 5.3. mailinfo.c was missing the compat header file,
and convert-objects.c needs to define a specific
_XOPEN_SOURCE as well as _XOPEN_SOURCE_EXTENDED.

git-merge-one-file: resurrect leading path creation.
Since we do not use git-update-index followed by
git-checkout-index -u to create the half-merged file on
conflicting case anymore, we need to make sure the leading
directories are created here.
Maybe a better solution would be to allow update-index to add to
higher stage, and checkout-index to extract from such, but that
is a change slightly bigger than I would like to have so close
to 1.0, so this should do for now.
Documentaiton (read-tree): update description of 3-way
The merge-one-file used to leave the working tree intact, but
it has long been changed to leave the merge result there since 2a68a8659f7dc55fd285d235ae2d19e7a8116c30 commit.
It was cumbersome to feed hash-object the file '-t' (you could
have said "./-t", though). Teach it '--' that terminates the
option list, like everybody else. There is no way to extract
usage string from the command either, so teach it "--help" as
well.
Not everybody can rely on /bin/sh to be sane, and we support
SHELL_PATH for that. Use it.
mktemp(1) is not used anywhere else in the core git. Do not
introduce dependency on it.
Not everybody's "which" gives a sane return value. For example,
on Solaris 'which XXX' says "no XXX in /usr/bin /bin ..." and
exits with zero status. The lesson here is to never use 'which'
in your scripts.

This attempts to clean up the way various compatibility
functions are defined and used.
- A new header file, git-compat-util.h, is introduced. This
looks at various NO_XXX and does necessary function name
replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
Makefile.
- Those function name replacements are removed from the Makefile.
- Common features such as usage(), die(), xmalloc() are moved
from cache.h to git-compat-util.h; cache.h includes
git-compat-util.h itself.
gitk: Some improvements for the code for updating the display
This should be more robust in the case that some does "Update" before
the initial drawing is finished. It also avoids having to reset the
list of children for each commit and reconstruct it.
The existing config.mak should satisfy almost everyone... You
can change the prefix and other vars catch the new setting
anyways. I had forgotten that ?= acts as = (lazy value binding)
and as not := (immediate value binding).

Documentation: shared repository management in tutorial.
The branch policy script I outlined was improved and polished by
Carl and posted on the list twice since then. It is a shame not
to pick it up, so replace the original outline in
howto/update-hook-example.txt with the latest from Carl.
Also talk about setting up git-shell to allow git-push/git-fetch
only SSH access to a shared repository host in the tutorial.
Mention documentation pages that talk about update and
post-update hooks from git-push, because a frequently asked
question is "I want X to happen when I push" and people would
not know to look at git-receive-pack documentation until they
understand that is what runs on the other end.
Again, dumb transport clients are too dumb to make use of the
top objects information to make a choice among multiple packs,
so computing these lines are useless for now. We could
resurrect them if needed later. Also dumb transport clients
presumably can do their own approximation by downloading idx
files to see how relevant each pack is for their fetch.
We tried to compute pack interdependency information in
$GIT_DIR/objects/info/packs, hoping that dumb transports would
make use of it when choosing from multiple choice, but that has
never materialized, so stop computing D lines for now.
sha1_file.c: make sure packs in an alternate odb is named properly.
We somehow ended up registering packs in alternate object
directories as "dir/object//pack/pack-*", which confusd the
update-server-info code very badly. Also we did not attempt to
detect a mistake of listing the object directory itself as one
of the alternates. This does not lead to incorrect behaviour,
but is simply wasteful, so try to do so when we are trivially
able to.
git.c: remove excess output for debugging when command is too long.
When the given command name was too long, we exited with a
message with the number of bytes of the final command name
inside parentheses, without saying what that number is. It was
only meant as a debugging aid while development, so remove it.

This switch was not documented properly. I decided not to mention

show-branch: allow glob pattern to name branches to show.
With this, you can say "git-show-branch topic/* master" to show
all the topic branches you have under .git/refs/heads/topic/ and
your master branch. Another example is "git-show-branch --list
v1.0*" to show all the v1.0 tags. You can disambiguate by
saying "heads/topic/*" to show only topic branches if you have
tags under .git/refs/tags/topic/ as well.
