2b958e790b repack: refactor setup of pack-objects cmd
A subsequent patch will teach repack to run pack-objects with some same
and some different arguments if repacking of promisor objects is
required. Refactor the setup of the pack-objects cmd so that setting up
the arguments common to both is done in a function.

1ace63bc39 rebase --exec: make it work with --rebase-merges
The idea of `--exec` is to append an `exec` call after each `pick`.

Since the introduction of fixup!/squash! commits, this idea was extended
to apply to "pick, possibly followed by a fixup/squash chain", i.e. an
exec would not be inserted between a `pick` and any of its corresponding
`fixup` or `squash` lines.

The current implementation uses a dirty trick to achieve that: it
assumes that there are only pick/fixup/squash commands, and then
*inserts* the `exec` lines before any `pick` but the first, and appends
a final one.

With the todo lists generated by `git rebase --rebase-merges`, this
simple implementation shows its problems: it produces the exact wrong
thing when there are `label`, `reset` and `merge` commands.

Let's change the implementation to do exactly what we want: look for
`pick` lines, skip any fixup/squash chains, and then insert the `exec`
line. Lather, rinse, repeat.

Note: we take pains to insert *before* comment lines whenever possible,
as empty commits are represented by commented-out pick lines (and we
want to insert a preceding pick's exec line *before* such a line, not
afterward).

While at it, also add `exec` lines after `merge` commands, because they
are similar in spirit to `pick` commands: they add new commits.

bf1a11f0a1 sideband: highlight keywords in remote sideband output
The colorization is controlled with the config setting "color.remote".

Supported keywords are "error", "warning", "hint" and "success". They
are highlighted if they appear at the start of the line, which is
common in error messages, eg.

   ERROR: commit is missing Change-Id

The Git push process itself prints lots of non-actionable messages
(eg. bandwidth statistics, object counters for different phases of the
process). This obscures actionable error messages that servers may
send back. Highlighting keywords in the sideband draws more attention
to those messages.

The background for this change is that Gerrit does server-side
processing to create or update code reviews, and actionable error
messages (eg. missing Change-Id) must be communicated back to the user
during the push. User research has shown that new users have trouble
seeing these messages.

The highlighting is done on the client rather than server side, so
servers don't have to grow capabilities to understand terminal escape
codes and terminal state. It also consistent with the current state
where Git is control of the local display (eg. prefixing messages with
"remote: ").

The highlighting can be configured using color.remote.<KEYWORD>
configuration settings. Since the keys are matched case insensitively,
we match the keywords case insensitively too.

Finally, this solution is backwards compatible: many servers already
prefix their messages with "error", and they will benefit from this
change without requiring a server update. By contrast, a server-side
solution would likely require plumbing the TERM variable through the
git protocol, so it would require changes to both server and client.

388d0ff6e5 git-update-index.txt: reword possibly confusing example
The following phrase could be interpreted multiple ways:
  "To pretend you have a file with mode and sha1 at path"

In particular, I can think of two:
  1. Pretend we have some new file, which happens to have a given mode
     and sha1
  2. Pretend one of the files we are already tracking has a different
     mode and sha1 than what it really does

I think people could easily assume either case while reading, but the
example command provided doesn't actually handle the first case, which
caused some minor frustration to at least one user.  Modify the example
command so that it correctly handles both cases, and re-order the
wording in a way that makes it more likely folks will assume the first
interpretation.  I believe the new example shouldn't pose any obstacles
to those wanting the second interpretation (at worst, they pass an
unnecessary extra flag).

bff7df7a87 git-config: document accidental multi-line setting in deprecated syntax
The bug was noticed when writing the previous patch; a fix for this bug
is not easy though: If we choose to ignore the case of the subsection
(and revert most of the code of the previous patch, just keeping
s/strncasecmp/strcmp/), then we'd introduce new sections using the
new syntax, such that

 --------
   [section.subsection]
     key = value1
 --------

  git config section.Subsection.key value2

would result in

 --------
   [section.subsection]
     key = value1
   [section.Subsection]
     key = value2
 --------

which is even more confusing. A proper fix would replace the first
occurrence of 'key'. As the syntax is deprecated, let's prefer to not
spend time on fixing the behavior and just document it instead.

2d84f13dcb config: fix case sensitive subsection names on writing
A user reported a submodule issue regarding a section mix-up,
but it could be boiled down to the following test case:

  $ git init test  && cd test
  $ git config foo."Bar".key test
  $ git config foo."bar".key test
  $ tail -n 3 .git/config
  [foo "Bar"]
        key = test
        key = test

Sub sections are case sensitive and we have a test for correctly reading
them. However we do not have a test for writing out config correctly with
case sensitive subsection names, which is why this went unnoticed in
6ae996f2ac (git_config_set: make use of the config parser's event
stream, 2018-04-09)

Unfortunately we have to make a distinction between old style configuration
that looks like

  [foo.Bar]
        key = test

and the new quoted style as seen above. The old style is documented as
case-agnostic, hence we need to keep 'strncasecmp'; although the
resulting setting for the old style config differs from the configuration.
That will be fixed in a follow up patch.

4aa5ff9409 sequencer: fix quoting in write_author_script
Single quotes should be escaped as \' not \\'. The bad quoting breaks
the interactive version of 'rebase --root' (which is used when there
is no '--onto' even if the user does not specify --interactive) for
authors that contain "'" as sq_dequote() called by read_author_ident()
errors out on the bad quoting.

For other interactive rebases this only affects external scripts that
read the author script and users whose git is upgraded from the shell
version of rebase -i while rebase was stopped when the author contains
"'". This is because the parsing in read_env_script() expected the
broken quoting.

This patch includes code to handle the broken quoting when
git has been upgraded while rebase was stopped. It does this by
detecting the missing "'" at the end of the GIT_AUTHOR_DATE line to see
if it should dequote \\' as "'". Note this is only implemented for
normal picks, not for creating a new root commit (rebase will stop with
an error complaining out bad quoting in that case).

The fallback code has been manually tested by reverting both the quoting
fixes in write_author_script() and the previous fix for the missing "'"
at the end of the GIT_AUTHOR_DATE line and running
t3404-rebase-interactive.sh.

Ideally rebase and am would share the same code for reading and
writing the author script, but this commit just fixes the immediate
bug.

0ed8d8da37 doc hash-function-transition: pick SHA-256 as NewHash
From a security perspective, it seems that SHA-256, BLAKE2, SHA3-256,
K12, and so on are all believed to have similar security properties.
All are good options from a security point of view.

SHA-256 has a number of advantages:

* It has been around for a while, is widely used, and is supported by
  just about every single crypto library (OpenSSL, mbedTLS, CryptoNG,
  SecureTransport, etc).

* When you compare against SHA1DC, most vectorized SHA-256
  implementations are indeed faster, even without acceleration.

* If we're doing signatures with OpenPGP (or even, I suppose, CMS),
  we're going to be using SHA-2, so it doesn't make sense to have our
  security depend on two separate algorithms when either one of them
  alone could break the security when we could just depend on one.

So SHA-256 it is.  Update the hash-function-transition design doc to
say so.

After this patch, there are no remaining instances of the string
"NewHash", except for an unrelated use from 2008 as a variable name in
t/t9700/test.pl.

6ec633059a t: factor out FUNNYNAMES as shared lazy prereq
A fair number of tests need to check that the filesystem supports file
names including "funny" characters, like newline, tab, and double-quote.
Jonathan Nieder suggested that this be extracted into a lazy prereq in
the top-level `test-lib.sh`. This patch effects that change.

The FUNNYNAMES prereq now uniformly requires support for newlines, tabs,
and double-quotes in filenames. This very slightly decreases the power
of some tests, which might have run previously on a system that supports
(e.g.) newlines and tabs but not double-quotes, but now will not. This
seems to me like an acceptable tradeoff for consistency.

One test (`t/t9902-completion.sh`) defined FUNNYNAMES to further require
the separators \034 through \037, the test for which was implemented
using the Bash-specific $'\034' syntax. I've elected to leave this one
as is, renaming it to FUNNIERNAMES.

After this patch, `git grep 'test_\(set\|lazy\)_prereq.*FUNNYNAMES'` has
only one result.

bd7dfa543e rerere: recalculate conflict ID when unresolved conflict is committed
Currently when a user doesn't resolve a conflict, commits the results,
and does an operation which creates another conflict, rerere will use
the ID of the previously unresolved conflict for the new conflict.
This is because the conflict is kept in the MERGE_RR file, which
'rerere' reads every time it is invoked.

After the new conflict is solved, rerere will record the resolution
with the ID of the old conflict.  So in order to replay the conflict,
both merges would have to be re-done, instead of just the last one, in
order for rerere to be able to automatically resolve the conflict.

Instead of that, assign a new conflict ID if there are still conflicts
in a file and the file had conflicts at a previous step.  This ID
matches the conflict we actually resolved at the corresponding step.

Note that there are no backwards compatibility worries here, as rerere
would have failed to even normalize the conflict before this patch
series.

4af32207bc rerere: teach rerere to handle nested conflicts
Currently rerere can't handle nested conflicts and will error out when
it encounters such conflicts.  Do that by recursively calling the
'handle_conflict' function to normalize the conflict.

Note that a conflict like this would only be produced if a user
commits a file with conflict markers, and gets a conflict including
that in a susbsequent operation.

The conflict ID calculation here deserves some explanation:

As we are using the same handle_conflict function, the nested conflict
is normalized the same way as for non-nested conflicts, which means
the ancestor in the diff3 case is stripped out, and the parts of the
conflict are ordered alphabetically.

The conflict ID is however is only calculated in the top level
handle_conflict call, so it will include the markers that 'rerere'
adds to the output.  e.g. say there's the following conflict:

    <<<<<<< HEAD
    1
    =======
    <<<<<<< HEAD
    3
    =======
    2
    >>>>>>> branch-2
    >>>>>>> branch-3~

it would be recorde as follows in the preimage:

    <<<<<<<
    1
    =======
    <<<<<<<
    2
    =======
    3
    >>>>>>>
    >>>>>>>

and the conflict ID would be calculated as

    sha1(1<NUL><<<<<<<
    2
    =======
    3
    >>>>>>><NUL>)

Stripping out vs. leaving the conflict markers in place in the inner
conflict should have no practical impact, but it simplifies the
implementation.

5ebbdad344 rerere: return strbuf from handle path
Currently we write the conflict to disk directly in the handle_path
function.  To make it re-usable for nested conflicts, instead of
writing the conflict out directly, store it in a strbuf and let the
caller write it out.

This does mean some slight increase in memory usage, however that
increase is limited to the size of the largest conflict we've
currently processed.  We already keep one copy of the conflict in
memory, and it shouldn't be too large, so the increase in memory usage
seems acceptable.

As a bonus this lets us get replace the rerere_io_putconflict function
with a trivial two line function.

Where previously we'd consider all files where an unmatched conflict

93406a282f rerere: fix crash with files rerere can't handle
Currently when a user does a conflict resolution and ends it (in any
way that calls 'git rerere' again) with a file 'rerere' can't handle,
subsequent rerere operations that are interested in that path, such as
'rerere clear' or 'rerere forget <path>' will fail, or even worse in
the case of 'rerere clear' segfault.

Such states include nested conflicts, or a conflict marker that
doesn't have any match.

This is because 'git rerere' calculates a conflict file and writes it
to the MERGE_RR file.  When the user then changes the file in any way
rerere can't handle, and then calls 'git rerere' on it again to record
the conflict resolution, the handle_file function fails, and removes
the 'preimage' file in the rr-cache in the process, while leaving the
ID in the MERGE_RR file.

Now when 'rerere clear' is run, it reads the ID from the MERGE_RR
file, however the 'fit_variant' function for the ID is never called as
the 'preimage' file does not exist anymore.  This means
'collection->status' in 'has_rerere_resolution' is NULL, and the
command will crash.

To fix this, remove the rerere ID from the MERGE_RR file in the case
when we can't handle it, just after the 'preimage' file was removed
and remove the corresponding variant from .git/rr-cache/.  Removing it
unconditionally is fine here, because if the user would have resolved
the conflict and ran rerere, the entry would no longer be in the
MERGE_RR file, so we wouldn't have this problem in the first place,
while if the conflict was not resolved.

Currently there is nothing left in this folder, as the 'preimage'
was already deleted by the 'handle_file' function, so 'remove_variant'
is a no-op.  Still call the function, to make sure we clean everything
up, in case we add some other files corresponding to a variant in the
future.

Note that other variants that have the same conflict ID will not be
touched.

b7446fcfdf t4150: fix broken test for am --scissors
Tests for "git am --[no-]scissors" [1] work in the following way:

 1. Create files with commit messages
 2. Use these files to create expected commits
 3. Generate eml file with patch from expected commits
 4. Create commits using git am with these eml files
 5. Compare these commits with expected

The test for "git am --scissors" is supposed to take an e-mail with a
scissors line and in-body "Subject:" header and demonstrate that the
subject line from the e-mail itself is overridden by the in-body header
and that only text below the scissors line is included in the commit
message of the commit created by the invocation of "git am --scissors".
However, the setup of the test incorrectly uses a commit without the
scissors line and without the in-body header in the commit message,
producing eml file not suitable for testing of "git am --scissors".

This can be checked by intentionally breaking is_scissors_line function
in mailinfo.c, for example, by changing string ">8", which is used by
the test. With such change the test should fail, but does not.

Fix broken test by generating eml file with scissors line and in-body
header "Subject:". Since the two tests for --scissors and --no-scissors
options are there to test cutting or keeping the commit message, update
both tests to change the test file in the same way, which allows us to
generate only one eml file to be passed to git am. To clarify the
intention of the test, give files and tags more explicit names.

[1]: introduced in bf72ac17d (t4150: tests for am --[no-]scissors,
     2015-07-19)

46af44b07d pull --rebase=<type>: allow single-letter abbreviations for the type
Git for Windows' original 4aa8b8c8283 (Teach 'git pull' to handle
--rebase=interactive, 2011-10-21) had support for the very convenient
abbreviation

	git pull --rebase=i

which was later lost when it was ported to the builtin `git pull`, and
it was not introduced before the patch eventually made it into Git as
f5eb87b98d (pull: allow interactive rebase with --rebase=interactive,
2016-01-13).

However, it is *really* a useful short hand for the occasional rebasing
pull on branches that do not usually want to be rebased.

So let's reintroduce this convenience, at long last.

beb188e22a add a script to diff rendered documentation
After making a change to the documentation, it's easy to
forget to check the rendered version to make sure it was
formatted as you intended. And simply doing a diff between
the two built versions is less trivial than you might hope:

  - diffing the roff or html output isn't particularly
    readable; what we really care about is what the end user
    will see

  - you have to tweak a few build variables to avoid
    spurious differences (e.g., version numbers, build
    times)

Let's provide a script that builds and installs the manpages
for two commits, renders the results using "man", and diffs
the result. Since this is time-consuming, we'll also do our
best to avoid repeated work, keeping intermediate results
between runs.

Some of this could probably be made a little less ugly if we
built support into Documentation/Makefile. But by relying
only on "make install-man" working, this script should work
for generating a diff between any two versions, whether they
include this script or not.

f1d15713fa builtin/submodule--helper: store update_clone information in a struct
The information that is printed for update_submodules in
'submodule--helper update-clone' and consumed by 'git submodule update'
is stored as a string per submodule. This made sense at the time of
48308681b0 (git submodule update: have a dedicated helper for cloning,
2016-02-29), but as we want to migrate the rest of the submodule update
into C, we're better off having access to the raw information in a helper
struct.

9eca701f69 git-submodule.sh: rename unused variables
The 'mode' variable is not used in cmd_update for its original purpose,
rename it to 'dummy' as it only serves the purpose to abort quickly
documenting this knowledge.

The variable 'stage' is also not used any more in cmd_update, so remove it.

This went unnoticed as first each function used the commonly used
submodule listing, which was converted in 74703a1e4d (submodule: rewrite
`module_list` shell function in C, 2015-09-02). When cmd_update was
using its own function starting in 48308681b0 (git submodule update:
have a dedicated helper for cloning, 2016-02-29), its removal was missed.

A later patch in this series also touches the communication between
the submodule helper and git-submodule.sh, but let's have this as
a preparatory patch, as it eases the next patch, which stores the
raw data instead of the line printed for this communication.
