Generally remote-curl would never see a URL that did not
have "proto:" at the beginning, as that is what tells git to
run the "git-remote-proto" helper (and git-remote-http, etc,
are aliases for git-remote-curl).
However, the special syntax "proto::something" will run
git-remote-proto with only "something" as the URL. So a
malformed URL like:
http::/example.com/repo.git
will feed the URL "/example.com/repo.git" to
git-remote-http. The resulting URL has no protocol, but the
code added by 372370f (http: use credential API to handle
proxy authentication, 2016-01-26) does not handle this case
and segfaults.
For the purposes of this code, we don't really care what the
exact protocol; only whether or not it is https. So let's
just assume that a missing protocol is not, and curl will
handle the real error (which is that the URL is nonsense).

When pack-objects is given --include-tag, it peels each tag
ref down to a non-tag object, and if that non-tag object is
going to be packed, we include the tag, too. But what
happens if we have a chain of tags (e.g., tag "A" points to
tag "B", which points to commit "C")?
We'll peel down to "C" and realize that we want to include
tag "A", but we do not ever consider tag "B", leading to a
broken pack (assuming "B" was not otherwise selected).
Instead, we have to walk the whole chain, adding any tags we
find to the pack.
Interestingly, it doesn't seem possible to trigger this
problem with "git fetch", but you can with "git clone
--single-branch". The reason is that we generate the correct
pack when the client explicitly asks for "A" (because we do
a real reachability analysis there), and "fetch" is more
willing to do so. There are basically two cases:
1. If "C" is already a ref tip, then the client can deduce
that it needs "A" itself (via find_non_local_tags), and
will ask for it explicitly rather than relying on the
include-tag capability. Everything works.
2. If "C" is not already a ref tip, then we hope for
include-tag to send us the correct tag. But it doesn't;
it generates a broken pack. However, the next step is
to do a follow-up run of find_non_local_tags(),
followed by fetch_refs() to backfill any tags we
learned about.
In the normal case, fetch_refs() calls quickfetch(),
which does a connectivity check and sees we have no
new objects to fetch. We just write the refs.
But for the broken-pack case, the connectivity check
fails, and quickfetch will follow-up with the remote,
asking explicitly for each of the ref tips. This picks
up the missing object in a new pack.
For a regular "git clone", we are similarly OK, because we
explicitly request all of the tag refs, and get a correct
pack. But with "--single-branch", we kick in tag
auto-following via "include-tag", but do _not_ do a
follow-up backfill. We just take whatever the server sent us
via include-tag and write out tag refs for any tag objects
we were sent. So prior to c6807a4 (clone: open a shortcut
for connectivity check, 2013-05-26), we actually claimed the
clone was a success, but the result was silently
corrupted! Since c6807a4, index-pack's connectivity
check catches this case, and we correctly complain.
The included test directly checks that pack-objects does not
generate a broken pack, but also confirms that "clone
--single-branch" does not hit the bug.
Note that tag chains introduce another interesting question:
if we are packing the tag "B" but not the commit "C", should
"A" be included?
Both before and after this patch, we do not include "A",
because the initial peel_ref() check only knows about the
bottom-most level, "C". To realize that "B" is involved at
all, we would have to switch to an incremental peel, in
which we examine each tagged object, asking if it is being
packed (and including the outer tag if so).
But that runs contrary to the optimizations in peel_ref(),
which avoid accessing the objects at all, in favor of using
the value we pull from packed-refs. It's OK to walk the
whole chain once we know we're going to include the tag (we
have to access it anyway, so the effort is proportional to
the pack we're generating). But for the initial selection,
we have to look at every ref. If we're only packing a few
objects, we'd still have to parse every single referenced
tag object just to confirm that it isn't part of a tag
chain.
This could be addressed if packed-refs stored the complete
tag chain for each peeled ref (in most cases, this would be
the same cost as now, as each "chain" is only a single
link). But given the size of that project, it's out of scope
for this fix (and probably nobody cares enough anyway, as
it's such an obscure situation). This commit limits itself
to just avoiding the creation of a broken pack.

We generate a series of packfiles test-1-$pack,
test-2-$pack, with different properties and then examine
them. However we always store the packname generated by
pack-objects in the variable packname_1. This probably was
meant to be packname_2 in the second test, but it turns out
that it doesn't matter: once we are done with the first
pack, we can just keep using the same $packname variable.
So let's drop the confusing "_1" parameter. At the same
time, let's give test-1 and test-2 more descriptive names,
which can help keep them straight (note that we _could_
likewise overwrite the packfiles in each test, but by using
separate filenames, we are sure that test 2 does not
accidentally use the packfile from test 1).

This test unpacks objects into a separate repository, and
accesses it by setting GIT_DIR in a subshell. We can do the
same thing these days by using "git init <repo>" and "git
-C". In most cases this is shorter, though when there are
multiple commands, we may end up repeating the "-C".
However, this repetition can actually be a good thing. This
patch also fixes a bug introduced by 512477b (tests: use
"env" to run commands with temporary env-var settings,
2014-03-18). That commit essentially converted:
(GIT_DIR=...; export GIT_DIR
cmd1 &&
cmd2)
into:
(GIT_DIR=... cmd1 &&
cmd2)
which obviously loses the GIT_DIR setting for cmd2 (we never
noticed the bug because it simply runs "cmd2" in the parent
repo, which means we were simply failing to test anything
interesting). By using "git -C" rather than a subshell, it
becomes quite obvious where each command is supposed to be
running.

We might wonder why our && chain check does not catch this case:
The && chain check uses a strange exit code with the expectation that
the second or later part of a broken && chain would not exit with this
particular code.
This expectation does not work in this case because __git_ps1, being
the first command in the second part of the broken && chain, records
the current exit code, does its work, and finally returns to the caller
with the recorded exit code. This fools our && chain check.

The function is used to set up the environment variable used in a
subprocess we spawn in a submodule directory. The callers set up a
child_process structure, find the working tree path of one submodule
and set .dir field to it, and then use start_command() API to spawn
the subprocess like "status", "fetch", etc.
When this happens, we expect that the ".git" (either a directory or
a gitfile that points at the real location) in the current working
directory of the subprocess MUST be the repository for the submodule.
If this ".git" thing is a corrupt repository, however, because
prepare_submodule_repo_env() unsets GIT_DIR and GIT_WORK_TREE, the
subprocess will see ".git", thinks it is not a repository, and
attempt to find one by going up, likely to end up in finding the
repository of the superproject. In some codepaths, this will cause
a command run with the "--recurse-submodules" option to recurse
forever.
By exporting GIT_DIR=.git, disable the auto-discovery logic in the
subprocess, which would instead stop it and report an error.

Currently, do_submodule_path will attempt locating the .git directory by
using read_gitfile on <path>/.git. If this fails it just assumes the
<path>/.git is actually a git directory.
This is good because it allows for handling submodules which were cloned
in a regular manner first before being added to the superproject.
Unfortunately this fails if the <path> is not actually checked out any
longer, such as by removing the directory.
Fix this by checking if the directory we found is actually a gitdir. In
the case it is not, attempt to lookup the submodule configuration and
find the name of where it is stored in the .git/modules/ directory of
the superproject.
If we can't locate the submodule configuration, this might occur because
for example a submodule gitlink was added but the corresponding
.gitmodules file was not properly updated. A die() here would not be
pleasant to the users of submodule diff formats, so instead, modify
do_submodule_path() to return an error code:
- git_pathdup_submodule() returns NULL when we fail to find a path.
- strbuf_git_path_submodule() propagates the error code to the caller.
Modify the callers of these functions to check the error code and fail
properly. This ensures we don't attempt to use a bad path that doesn't
match the corresponding submodule.
Because this change fixes add_submodule_odb() to work even if the
submodule is not checked out, update the wording of the submodule log
diff format to correctly display that the submodule is "not initialized"
instead of "not checked out"

Each test run generates a "count" file in t/test-results
that stores the number of successful, failed, etc tests.
If you run "t1234-foo.sh", that file is named as
"t/test-results/t1234-foo-$$.count"
The addition of the PID there is serving no purpose, and
makes analysis of the count files harder.
The presence of the PID dates back to 2d84e9f (Modify
test-lib.sh to output stats to t/test-results/*,
2008-06-08), but no reasoning is given there. Looking at the
current code, we can see that other files we write to
test-results (like *.exit and *.out) do _not_ have the PID
included. So the presence of the PID does not meaningfully
allow one to store the results from multiple runs anyway.
Moreover, anybody wishing to read the *.count files to
aggregate results has to deal with the presence of multiple
files for a given test (and figure out which one is the most
recent based on their timestamps!). The only consumer of
these files is the aggregate.sh script, which arguably gets
this wrong. If a test is run multiple times, its counts will
appear multiple times in the total (I say arguably only
because the desired semantics aren't documented anywhere,
but I have trouble seeing how this behavior could be
useful).
So let's just drop the PID, which fixes aggregate.sh, and
will make new features based around the count files easier
to write.
Note that since the count-file may already exist (when
re-running a test), we also switch the "cat" from appending
to truncating. The use of append here was pointless in the
first place, as we expected to always write to a unique file.

If the repository is empty, or if the file would lexicographically be

When the index is locked and child processes inherit the handle to
said lock and the parent process wants to remove the lock before the
child process exits, on Windows there is a problem: it won't work
because files cannot be deleted if a process holds a handle on them.
The symptom:
Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed.
Should I try again? (y/n)
Spawning child processes with bInheritHandles==FALSE would not work
because no file handles would be inherited, not even the hStdXxx
handles in STARTUPINFO (stdin/stdout/stderr).
Opening every file with O_NOINHERIT does not work, either, as e.g.
git-upload-pack expects inherited file handles.
This leaves us with the only way out: creating temp files with the
O_NOINHERIT flag. This flag is Windows-specific, however. For our
purposes, it is equivalent to O_CLOEXEC (which does not exist on
Windows), so let's just open temporary files with the O_CLOEXEC flag and
map that flag to O_NOINHERIT on Windows.
As Eric Wong pointed out, we need to be careful to handle the case where
the Linux headers used to compile Git support O_CLOEXEC but the Linux
kernel used to run Git does not: it returns an EINVAL.
This fixes the test that we just introduced to demonstrate the problem.

On Windows, a file cannot be removed unless all file handles to it have

The example chosen for this test is a custom merge driver that indeed
has no idea that it blocks the deletion of index.lock. The full use case
is a daemon that lives on after the merge, with subsequent invocations
handing off to the daemon, thereby avoiding hefty start-up costs. We

expect that the submodules are created with references to the submodules
of the given alternate for the superproject.
An initial attempt to do this was presented to the mailing list, which
used flags that are passed around ("--super-reference") that instructed
the submodule clone to look for a reference in the submodules of the
referenced superproject. This is not well thought out, as any further
`submodule update` should also respect the initial setup.
When a new submodule is added to the superproject and the alternate
of the superproject does not know about that submodule yet, we rather
error out informing the user instead of being unclear if we did or did
not use a submodules alternate.
To solve this problem introduce new options that store the configuration
for what the user wanted originally.

The "t/" hierarchy is prone to get an unusual pathname; "make test"
has been taught to make sure they do not contain paths that cannot
be checked out on Windows (and the mechanism can be reusable to
catch pathnames that are not portable to other platforms as need
arises).
* js/test-lint-pathname:
t/Makefile: ensure that paths are valid on platforms we care
A small test clean-up for a topic introduced in v2.9.1 and later.
* sg/reflog-past-root:
t1410: remove superfluous 'git reflog' from the 'walk past root' test
The idea of the --git-path option is not only to avoid having to
prefix paths with the output of --git-dir all the time, but also to
respect overrides for specific common paths inside the .git directory
(e.g. `git rev-parse --git-path objects` will report the value of the
environment variable GIT_OBJECT_DIRECTORY, if set).
When introducing the core.hooksPath setting, we forgot to adjust
git_path() accordingly. This patch fixes that.
While at it, revert the special-casing of core.hooksPath in
run-command.c, as it is now no longer needed.

Some pathnames that are okay on ext4 and on HFS+ cannot be checked
out on Windows. Tests that want to see operations on such paths on
filesystems that support them must do so behind appropriate test
prerequisites, and must not include them in the source tree (instead
they should create them when they run). Otherwise, the source tree
cannot even be checked out.
Make sure that double-quotes, asterisk, colon, greater/less-than,
question-mark, backslash, tab, vertical-bar, as well as any non-ASCII
characters never appear in the pathnames with a new test-lint-* target
as part of a `make test`. To that end, we call `git ls-files` (ensuring
that the paths are quoted properly), relying on the fact that paths
containing non-ASCII characters are quoted within double-quotes.
In case that the source code does not actually live in a Git
repository (e.g. when extracted from a .zip file), or that the `git`
executable cannot be executed, we simply ignore the error for now; In
that case, our trusty Continuous Integration will be the last line of
defense and catch any problematic file name.
Noticed when a topic wanted to add a pathname with '>' in it. A
check like this will prevent a similar problems from happening in the
future.

At the moment difftool's "trust exit code" logic always suppresses the
exit status of the diff utility we invoke. This is useful because we
don't want to exit just because diff returned "1" because the files
differ, but it's confusing if the shell returns an error because the
selected diff utility is not found.
POSIX specifies 127 as the exit status for "command not found", 126 for
"command found but is not executable" and values greater than 128 if the
command terminated because it received a signal [1] and at least bash
and dash follow this specification, while diff utilities generally use
"1" for the exit status we want to ignore.
Handle any value of 126 or greater as a special value indicating that
some form of fatal error occurred.
