Documentation/config.txt: fix typo in core.alternateRefsCommand

In [1] Git learned about 'core.alternateRefsCommand', and with it, the
accompanying documentation. However, this documentation included a typo
involving the verb tense of "produced".

Match the tense of the surrounding bits by correcting this typo.

cocci: simplify "if (++u > 1)" to "if (u++)"

It is more common to use post-increment than pre-increment when the
side effect is the primary thing we want in our code and in C in
general (unlike C++).

Initializing a variable to 0, incrementing it every time we do
something, and checking if we have already done that thing to guard
the code to do that thing, is easier to understand when written

if (u++)
; /* we've done that! */
else
do_it(); /* just once. */

but if you try to use pre-increment, you end up with a less natural
looking

if (++u > 1)

rebase (autostash): use an explicit OID to apply the stash

When `git stash apply <argument>` sees an argument that consists only of
digits, it tries to be smart and interpret it as `stash@{<number>}`.

Unfortunately, an all-digit hash (which is unlikely but still possible)
is therefore misinterpreted as `stash@{<n>}` reflog.

To prevent that from happening, let's append `^0` after the stash hash,
to make sure that it is interpreted as an OID rather than as a number.

rebase (autostash): store the full OID in <state-dir>/autostash

It was reported by Gábor Szeder and analyzed by Alban Gruin that the
built-in rebase stores only abbreviated stash hashes in the `autostash`
file.

This is problematic e.g. in t5520-pull.sh, where the abbreviated hash is
so short that it sometimes consists only of digits, which are
subsequently mistaken ("DWIMmed") for numbers by `git stash apply`.

Let's align the behavior of the built-in rebase with the scripted rebase
and store the full stash hash instead. That makes it a lot less likely
that it consists only of digits.

gpg-interface.c: detect and reject multiple signatures on commits

GnuPG supports creating signatures consisting of multiple signature
packets. If such a signature is verified, it outputs all the status
messages for each signature separately. However, git currently does not
account for such scenario and gets terribly confused over getting
multiple *SIG statuses.

For example, if a malicious party alters a signed commit and appends
a new untrusted signature, git is going to ignore the original bad
signature and report untrusted commit instead. However, %GK and %GS
format strings may still expand to the data corresponding
to the original signature, potentially tricking the scripts into
trusting the malicious commit.

Given that the use of multiple signatures is quite rare, git does not
support creating them without jumping through a few hoops, and finally
supporting them properly would require extensive API improvement, it
seems reasonable to just reject them at the moment.

diff: don't attempt to strip prefix from absolute Windo... Johannes Sixt Fri, 19 Oct 2018 16:58:07 +0000 (18:58 +0200)

diff: don't attempt to strip prefix from absolute Windows paths

git diff can be invoked with absolute paths. Typically, this triggers
the --no-index case. Then the absolute paths remain in the file names
that are printed in the output.

There is one peculiarity, though: When the command is invoked from a
a sub-directory in a repository, then it is attempted to strip the
sub-directory from the beginning of relative paths. Yet, to detect a
relative path the code just checks for an initial forward slash.
This mistakes a Windows style path like "D:/base" as a relative path
and the output looks like this, for example:

D:\dir\test\one>git -P diff --numstat D:\dir\base D:\dir\diff
1 1 ir/{base => diff}/1.txt

where the correct output should be

D:\dir\test\one>git -P diff --numstat D:\dir\base D:\dir\diff
1 1 D:/dir/{base => diff}/1.txt

If the sub-directory where 'git diff' is invoked is sufficiently deep
that the prefix becomes longer than the path to be printed, then the
subsequent code accesses the path out of bounds.

Use is_absolute_path() to detect Windows style absolute paths.

One might wonder whether the check for a directory separator that
is visible in the patch context should be changed from == '/' to
is_dir_sep() or not. It turns out not to be necessary. That code
only ever investigates paths that have undergone pathspec
normalization, after which there are only forward slashes even on
Windows.

receive: denyCurrentBranch=updateinstead should not blindly update

The handling of receive.denyCurrentBranch=updateInstead was added to
a switch statement that handles other values of the variable, but
all the other case arms only checked a condition to reject the
attempted push, or let later logic in the same function to still
intervene, so that a push that does not fast-forward (which is
checked after the switch statement in question) is still rejected.

But the handling of updateInstead incorrectly took immediate effect,
without giving other checks a chance to intervene.

Instead of calling update_worktree() that causes the side effect
immediately, just note the fact that we will need to call the
function later, and first give other checks a chance to reject the
request. After the update-hook gets a chance to reject the push
(which happens as the last step in a series of checks), call
update_worktree() when we earlier detected the need to.

pack-objects (mingw): initialize `packing_data` mutex in the correct spot

In 9ac3f0e5b3e4 (pack-objects: fix performance issues on packing large
deltas, 2018-07-22), a mutex was introduced that is used to guard the
call to set the delta size. This commit even added code to initialize
it, but at an incorrect spot: in `init_threaded_search()`, while the
call to `oe_set_delta_size()` (and hence to `packing_data_lock()`) can
happen in the call chain `check_object()` <- `get_object_details()` <-
`prepare_pack()` <- `cmd_pack_objects()`, which is long before the
`prepare_pack()` function calls `ll_find_deltas()` (which initializes
the threaded search).

Another tell-tale that the mutex was initialized in an incorrect spot is
that the function to initialize it lives in builtin/, while the code
that uses the mutex is defined in a libgit.a header file.

Let's use a more appropriate function: `prepare_packing_data()`, which
not only lives in libgit.a, but *has* to be called before the
`packing_data` struct is used that contains that mutex.

This fixes https://github.com/git-for-windows/git/issues/1839.

commit-reach: fix first-parent heuristicDerrick Stolee Thu, 18 Oct 2018 17:24:40 +0000 (10:24 -0700)

commit-reach: fix first-parent heuristic

The algorithm in can_all_from_reach_with_flags() performs a depth-
first-search, terminated by generation number, intending to use
a hueristic that "important" commits are found in the first-parent
history. This heuristic is valuable in scenarios like fetch
negotiation.

However, there is a problem! After the search finds a target commit,
it should pop all commits off the stack and mark them as "can reach".
This logic is incorrect, so the algorithm instead walks all reachable
commits above the generation-number cutoff.

The existing algorithm is still an improvement over the previous
algorithm, as the worst-case complexity went from quadratic to linear.
The performance measurement at the time was good, but not dramatic.
By fixing this heuristic, we reduce the number of walked commits.

We can also re-run the performance tests from commit 4fbcca4e
"commit-reach: make can_all_from_reach... linear".

Performance was measured on the Linux repository using
'test-tool reach can_all_from_reach'. The input included rows seeded by
tag values. The "small" case included X-rows as v4.[0-9]* and Y-rows as
v3.[0-9]*. This mimics a (very large) fetch that says "I have all major
v3 releases and want all major v4 releases." The "large" case included
X-rows as "v4.*" and Y-rows as "v3.*". This adds all release-candidate
tags to the set, which does not greatly increase the number of objects
that are considered, but does increase the number of 'from' commits,
demonstrating the quadratic nature of the previous code.

Small Case:

4fbcca4e~1: 0.85 s
4fbcca4e: 0.26 s (num_walked: 1,011,035)
HEAD: 0.14 s (num_walked: 8,601)

Large Case:

4fbcca4e~1: 24.0 s
4fbcca4e: 0.12 s (num_walked: 503,925)

config.mak.dev: enable -Wunused-function

We explicitly omitted -Wunused-function when we added
-Wextra, but there is no need: the current code compiles
cleanly with it. And it's worth having, since it can let you
know when there are cascading effects from a cleanup (e.g.,
deleting one function lets you delete its static helpers).

There are cases where we may need an unused function to
exist, but we can handle these easily:

- macro-generated code like commit-slab; there we have the
MAYBE_UNUSED annotation to silence the compiler

- conditional compilation, where we may or may not need a
static helper. These generally fall into one of two
categories:

- the call should not be conditional, but rather the
function body itself should be (and may just be a
no-op on one side of the #if). That keeps the
conditional pollution out of the main code.

- call-chains of static helpers should all be in the
same #if block, so they are all-or-nothing

And if there's some case that doesn't cover, we still
have MAYBE_UNUSED as a fallback.

ci: add optional test variables

The commit-graph and multi-pack-index features introduce optional
data structures that are not required for normal Git operations.
It is important to run the normal test suite without them enabled,
but it is helpful to also run the test suite using them.

Our continuous integration scripts include a second test stage that
runs with optional GIT_TEST_* variables enabled. Add the following
two variables to that stage:

GIT_TEST_COMMIT_GRAPH
GIT_TEST_MULTI_PACK_INDEX

This will slow down the operation, as we build a commit-graph file
after every 'git commit' operation and build a multi-pack-index
during every 'git repack' operation. However, it is important that
future changes are compatible with these features.

merge-recursive: avoid showing conflicts with merge... Elijah Newren Tue, 16 Oct 2018 20:19:48 +0000 (13:19 -0700)

merge-recursive: avoid showing conflicts with merge branch before HEAD

We want to load unmerged entries from HEAD into the index at stage 2 and
from MERGE_HEAD into stage 3. Similarly, folks expect merge conflicts
to look like

<<<<<<<< HEAD
content from our side
========
content from their side
>>>>>>>> MERGE_HEAD

not

<<<<<<<< MERGE_HEAD
content from their side
========
content from our side
>>>>>>>> HEAD

The correct order usually comes naturally and for free, but with renames
we often have data in the form {rename_branch, other_branch}, and
working relative to the rename first (e.g. for rename/add) is more
convenient elsewhere in the code. Address the slight impedance
mismatch by having some functions re-call themselves with flipped
arguments when the branch order is reversed.

Note that setup_rename_conflict_info() has one asymmetry in it, in
setting dst_entry1->processed=0 but not doing similarly for
dst_entry2->processed. When dealing with rename/rename and similar
conflicts, we do not want the processing to happen twice, so the
desire to only set one of the entries to unprocessed is intentional.
So, while this change modifies which branch's entry will be marked as
unprocessed, that dovetails nicely with putting HEAD first so that we
get the index stage entries and conflict markers in the right order.

merge-recursive: improve auto-merging messages with... Elijah Newren Tue, 16 Oct 2018 20:19:47 +0000 (13:19 -0700)

merge-recursive: improve auto-merging messages with path collisions

Each individual file involved in a rename could have also been modified
on both sides of history, meaning it may need to have content merges.
If two such files are renamed into the same location, then on top of the
two natural auto-merging messages we also have to two-way merge the
result, giving us messages that look like

Auto-merging somefile.c (was somecase.c)
Auto-merging somefile.c (was somefolder.c)
Auto-merging somefile.c

However, despite the fact that I was the one who put the "(was %s)"
portions into the messages (and just a few months ago), I was still
initially confused when running into a rename/rename(2to1) case and
wondered if somefile.c had been merged three times. Update this to
instead be:

Auto-merging version of somefile.c from somecase.c
Auto-merging version of somefile.c from someportfolio.c
Auto-merging somefile.c

This is an admittedly long set of messages for a single path, but you
only get all three messages when dealing with the rare case of a
rename/rename(2to1) conflict where both sides of both original files
were also modified, in conflicting ways.

However, it seems weird that we'd check those cases here (and provide

git-p4: fully support unshelving changelistsLuke Diamand Mon, 15 Oct 2018 11:14:08 +0000 (12:14 +0100)

git-p4: fully support unshelving changelists

The previous git-p4 unshelve support would check for changes
in Perforce to the files being unshelved since the original
shelve, and would complain if any were found.

This was to ensure that the user wouldn't end up with both the
shelved change delta, and some deltas from other changes in their
git commit.

e.g. given fileA:
the
quick
brown
fox

change1: s/the/The/ <- p4 shelve this change
change2: s/fox/Fox/ <- p4 submit this change
git p4 unshelve 1 <- FAIL

This change teaches the P4Unshelve class to always create a parent
commit which matches the P4 tree (for the files being unshelved) at
the point prior to the P4 shelve being created (which is reported
in the p4 description for a shelved changelist).

That then means git-p4 can always create a git commit matching the
P4 shelve that was originally created, without any extra deltas.

The user might still need to use the --origin option though - there
is no way for git-p4 to work out the versions of all of the other
*unchanged* files in the shelve, since this information is not recorded
by Perforce.

Additionally this fixes handling of shelved 'move' operations.

git-p4: unshelve into refs/remotes/p4-unshelved, not... Luke Diamand Mon, 15 Oct 2018 11:14:07 +0000 (12:14 +0100)

git-p4: unshelve into refs/remotes/p4-unshelved, not refs/remotes/p4/unshelved

The branch detection code looks for branches under refs/remotes/p4/...
and can end up getting confused if there are unshelved changes in
there as well. This happens in the function p4BranchesInGit().

Instead, put the unshelved changes into refs/remotes/p4-unshelved/<N>.

http: add support for selecting SSL backends at runtimeJohannes Schindelin Mon, 15 Oct 2018 10:14:43 +0000 (03:14 -0700)

http: add support for selecting SSL backends at runtime

As of version 7.56.0, curl supports being compiled with multiple SSL
backends.

This patch adds the Git side of that feature: by setting http.sslBackend
to "openssl" or "schannel", Git for Windows can now choose the SSL
backend at runtime.

This comes in handy on Windows because Secure Channel ("schannel") is
the native solution, accessing the Windows Credential Store, thereby
allowing for enterprise-wide management of certificates. For historical
reasons, Git for Windows needs to support OpenSSL still, as it has
previously been the only supported SSL backend in Git for Windows for
almost a decade.

The patch has been carried in Git for Windows for over a year, and is
considered mature.

mingw: use domain information for default email

When a user is registered in a Windows domain, it is really easy to
obtain the email address. So let's do that.

getpwuid(mingw): provide a better default for the user name

We do have the excellent GetUserInfoEx() function to obtain more
detailed information of the current user (if the user is part of a
Windows domain); Let's use it.

Suggested by Lutz Roeder.

To avoid the cost of loading Secur32.dll (even lazily, loading DLLs
takes a non-neglibile amount of time), we use the established technique
to load DLLs only when, and if, needed.
