The Makefile tweak NO_ICONV is meant to allow Git to be built without
iconv in case iconv is not installed or is otherwise dysfunctional.
However, NO_ICONV's disabling of iconv is incomplete and can incorrectly
allow "-liconv" to slip into the linker flags when NEEDS_LIBICONV is
defined, which breaks the build when iconv is not installed.
On some platforms, iconv lives directly in libc, whereas, on others it
resides in libiconv. For the latter case, NEEDS_LIBICONV instructs the
Makefile to add "-liconv" to the linker flags. config.mak.uname
automatically defines NEEDS_LIBICONV for platforms which require it.
The adding of "-liconv" is done unconditionally, despite NO_ICONV.
Work around this problem by making NO_ICONV take precedence over
NEEDS_LIBICONV.

Some of our tests try to make sure Git behaves sensibly in a
read-only directory, by dropping 'w' permission bit before doing a
test and then restoring it after it is done. The latter is needed
for the test framework to clean after itself without leaving a
leftover directory that cannot be removed.
Ancient parts of tests however arrange the above with
chmod a-w . &&
... do the test ...
status=$?
chmod 775 .
(exit $status)
which obviously would not work if the test somehow dies before it
has the chance to do "chmod 775". Rewrite them by following a more
robust pattern recently written tests use, which is
test_when_finished "chmod 775 ." &&
chmod a-w . &&
... do the test ...

When a submodules work tree is removed, we should unset its core.worktree
setting as the worktree is no longer present. This is not just in line
with the conceptual view of submodules, but it fixes an inconvenience
for looking at submodules that are not checked out:
git clone --recurse-submodules git://github.com/git/git && cd git &&
git checkout --recurse-submodules v2.13.0
git -C .git/modules/sha1collisiondetection log
fatal: cannot chdir to '../../../sha1collisiondetection': \
No such file or directory
With this patch applied, the final call to git log works instead of dying
in its setup, as the checkout will unset the core.worktree setting such
that following log will be run in a bare repository.
This patch covers all commands that are in the unpack machinery, i.e.
checkout, read-tree, reset. A follow up patch will address
"git submodule deinit", which will also make use of the new function
submodule_unset_core_worktree(), which is why we expose it in this patch.

When fetching with recursing into submodules, the fetch logic inspects
the superproject which submodules actually need to be fetched. This is
tricky for submodules that were renamed in the fetched range of commits.
This was implemented in c68f837576 (implement fetching of moved
submodules, 2017-10-16), and this patch fixes a mistake in the logic
there.
When the warning is printed, the `name` might be NULL as
default_name_or_path can return NULL, so fix the warning to use the path
as obtained from the diff machinery, as that is not NULL.
While at it, make sure we only attempt to load the submodule if a git
directory of the submodule is found as default_name_or_path will return
NULL in case the git directory cannot be found. Note that passing NULL
to submodule_from_name is just a semantic error, as submodule_from_name
accepts NULL as a value, but then the return value is not the submodule
that was asked for, but some arbitrary other submodule. (Cf. 'config_from'
in submodule-config.c: "If any parameter except the cache is a NULL
pointer just return the first submodule. Can be used to check whether
there are any submodules parsed.")

Fetch-pack --all became broken with respect to unusual tags in

and was fixed only recently in e9502c0a7f (fetch-pack: don't try to fetch

In order to be sure fetching funky tags will never break, let's
explicitly test all relevant cases with 4 tag objects pointing to 1) a

tag objects themselves are referenced from under regular refs/tags/*

The buffer being passed to zlib includes a NUL terminator that git
needs to keep in place. unpack_compressed_entry() attempts to detect
the case that the source buffer hasn't been fully consumed by
checking to see if the destination buffer has been over consumed.
This causes a problem, that more recent zlib patches have been
poisoning the unconsumed portions of the buffer which overwrites
the NUL byte, while correctly returning length and status.
Let's place the NUL at the end of the buffer after inflate returns
to assure that it doesn't result in problems for git even if its
been overwritten by zlib.

Mention that this feature works with some commands (merge and cherry-pick,
implying that it also works with commands that build on these like rebase
-m and rebase -i). Explicitly mentioning two commands hopefully implies
that it may not always work with other commands (am, and rebase without
flags that imply either -m or -i).
Also, since the directory rename detection from this cycle was
specifically added in merge-recursive and not diffcore-rename, remove the
'in "diff" family" phrase from the note. (Folks have requested in the
past that `git diff` detect directory renames and somehow simplify its

The "autodie" module was added in Perl 5.10.1, but our INSTALL
document says "version 5.8 or later is needed".
As discussed in <87efhfvxzu.fsf@evledraar.gmail.com> this script is in
contrib/, so we might not want to apply that policy, however in this
case "autodie" was recently added as a "gratuitous safeguard" in
786ef50a23 ("git-credential-netrc: accept gpg option",
2018-05-12) (see
<CAHqJXRE8OKSKcck1APHAHccLZhox+tZi8nNu2RA74RErX8s3Pg@mail.gmail.com>).
Looking at it more carefully the addition of "autodie" inadvertently
introduced a logic error, since having it is equivalent to this patch:
@@ -245,10 +244,10 @@ sub load_netrc {
if ($gpgmode) {
my @cmd = ($options{'gpg'}, qw(--decrypt), $file);
log_verbose("Using GPG to open $file: [@cmd]");

} else {
log_verbose("Opening $file...");
- open $io, '<', $file;
+ open $io, '<', $file or die "$file: $!$!;
}
# nothing to do if the open failed (we log the error later)
As shown in the context the intent of that code is not do die but to
log the error later.
Per my reading of the file this was the only thing autodie was doing
in this file (there was no other code it altered). So let's remove it,
both to fix the logic error and to get rid of the dependency.

git-p4 originally would fetch changes in one query. On large repos this
could fail because of the limits that Perforce imposes on the number of
items returned and the number of queries in the database.
To fix this, git-p4 learned to query changes in blocks of 512 changes,
However, this can be very slow - if you have a few million changes,
with each chunk taking about a second, it can be an hour or so.
Although it's possible to tune this value manually with the
"--changes-block-size" option, it's far from obvious to ordinary users
that this is what needs doing.
This change alters the block size dynamically by looking for the
specific error messages returned from the Perforce server, and reducing
the block size if the error is seen, either to the limit reported by the
server, or to half the current block size.
That means we can start out with a very large block size, and then let
it automatically drop down to a value that works without error, while
still failing correctly if some other error occurs.

This change lays some groundwork for better handling of rowcount errors
from the server, where it fails to send us results because we requested
too many.
It adds an option to p4CmdList() to return errors as a Python exception.
The exceptions are derived from P4Exception (something went wrong),
P4ServerException (the server sent us an error code) and
P4RequestSizeException (we requested too many rows/results from the
server database).
This makes the code that handles the errors a bit easier.

master then run git-p4 submit. It can be very annoying to switch

Add option --commit to command 'git-p4 submit' in order to submit
only specified commit(s) in p4.
On a daily work developping software with big compilation time, one
may not want to rebase on his local git tree, in order to avoid long

Add option --disable-rebase to command 'git-p4 submit' in order to

These functions were added because processing of these conflicts needed
to be deferred until process_entry() in order to get D/F conflicts and
such right. The number of these has grown over time, and now include
some whose name is misleading:
* conflict_rename_normal() is for handling normal file renames; a
typical rename may need content merging, but we expect conflicts
from that to be more the exception than the rule.
* conflict_rename_via_dir() will not be a conflict; it was just an
add that turned into a move due to directory rename detection.
(If there was a file in the way of the move, that would have been
detected and reported earlier.)
* conflict_rename_rename_2to1 and conflict_rename_add (the latter
of which doesn't exist yet but has been submitted before and I
intend to resend) technically might not be conflicts if the
colliding paths happen to match exactly.
Rename this family of functions to handle_rename_*().
Also rename handle_renames() to detect_and_process_renames() both to make
it clearer what it does, and to differentiate it as a pre-processing step
from all the handle_rename_*() functions which are called from
process_entry().

We had an enum of rename types which included RENAME_DIR; this name felt
misleading since it was not about an entire directory but was a status for
each individual file add that occurred within a renamed directory.
Since this type is for signifying that the files in question were being
renamed due to directory rename detection, rename this enum value to
RENAME_VIA_DIR.
Make a similar change to the conflict_rename_dir() function, and add a

v2.18.0-rc0~90^2 (completion: reduce overhead of clearing cached
--options, 2018-04-18) worked around a bug in bash's "set" builtin on
MacOS by using compgen instead. It was careful to avoid breaking zsh
by guarding this workaround with
if [[ -n ${ZSH_VERSION-}} ]]
Alas, this interacts poorly with git-completion.zsh's bash emulation:
ZSH_VERSION='' . "$script"
Correct it by instead using a new GIT_SOURCING_ZSH_COMPLETION shell
variable to detect whether git-completion.bash is being sourced from
git-completion.zsh. This way, the zsh variant is used both when run
from zsh directly and when run via git-completion.zsh.
Reproduction recipe:
1. cd git/contrib/completion && cp git-completion.zsh _git
2. Put the following in a new ~/.zshrc file:
autoload -U compinit; compinit
autoload -U bashcompinit; bashcompinit
fpath=(~/src/git/contrib/completion $fpath)
3. Open zsh and "git <TAB>".
With this patch:

When "fetch-pack --all" sees a tag-to-blob on the remote, it
tries to fetch both the tag itself ("refs/tags/foo") and the
peeled value that the remote advertises ("refs/tags/foo^{}").
Asking for the object pointed to by the latter can cause
upload-pack to complain with "not our ref", since it does
not mark the peeled objects with the OUR_REF (unless they
were at the tip of some other ref).
Arguably upload-pack _should_ be marking those peeled
objects. But it never has in the past, since clients would
generally just ask for the tag and expect to get the peeled
value along with it. And that's how "git fetch" works, as
well as older versions of "fetch-pack --all".
The problem was introduced by 5f0fc64513 (fetch-pack:
eliminate spurious error messages, 2012-09-09). Before then,
the matching logic was something like:
if (refname is ill-formed)
do nothing
else if (doing --all)
always consider it matched
else
look through list of sought refs for a match
That commit wanted to flip the order of the second two arms
of that conditional. But we ended up with:
if (refname is ill-formed)
do nothing
else
look through list of sought refs for a match
if (--all and no match so far)
always consider it matched
That means tha an ill-formed ref will trigger the --all
conditional block, even though we should just be ignoring
it. We can fix that by having a single "else" with all of
the well-formed logic, that checks the sought refs and
"--all" in the correct order.
