Our usual style in the test scripts is to indent here
documents with tabs, and use "<<-" to strip the tabs. The
result is easier to read.
This old test script did not do so in its inception, and
further tests added onto it followed the local style. Let's
bring it in line with our usual style.
Some of the tests actually care quite a bit about
whitespace, but none of them do so at the beginning of the
line (because they use things like qz_to_tab_space to avoid
depending on the literal whitespace), so we can do a fairly
mechanical conversion.
Most of the here-docs also use interpolation, so they have
been left as "<<-EOF". In a few cases, though, where
interpolation was not in use, I've converted them to
"<<-\EOF" to match our usual "don't interpolate unless you
need to" style.

The test currently does something like:
do_one() &&
do_two() &&
test_expect_success ...
We generally avoid performing actions at the top-level of
the script (outside of a test_expect block) for two reasons:
1. The test harness is not checking and reporting if they
fail.
2. Their output is not handled correctly (not hidden by
default, nor shown with "-v").
Using &&-chains seems like it should help with (1), but it
doesn't. If either of the commands fails, we simply skip
running the follow-on test entirely, and the test harness
has no idea.
We can fix this by pushing that setup into its own block.
It _could_ go into the following test block, but since the
result in this case is used by multiple tests, it's more
clear to mark it explicitly as a distinct setup step.

We prefer a space between the function name and the parentheses, and no
space inside the parentheses.
The opening "{" should also be on the same line.

These tests are irrelevant under GETTEXT_POISON because they test text

This allows us to use common test infrastructure and parallelize
the tests. For now, GIT_SVN_TEST_HTTPD=true needs to be set to
enable the SVN HTTP tests because we reuse the same test cases
for both file:// and http:// SVN repositories. SVN_HTTPD_PORT
is no longer honored.
Tested under Apache 2.2 and 2.4 on Debian 7.x (wheezy) and
8.x (jessie), respectively.

not.
The test suite is directed at people reading t/README where we keep all

On Windows, it is already pretty expensive to try to recreate the stat()
data that Git assumes is cheap to obtain. To make things halfway decent
in performance, we even have to skip emulating the inode and to
determine the number of hard links.
This is not a huge problem, usually, as either the size or the mtime or
the ctime are tell-tale enough to say when a file has changed, and even
if not, those changes are typically made after the index file was
written, triggering a rehashing of the files' contents.
The t4130-apply-criss-cross-rename test case, however, requires the
inode to determine that files of equal size were swapped, as renaming
files does not update their mtime. Every once in a while, t4130 fails
on Windows because of this missing piece.
Equal file sizes are not crucial for the test cases, however. Hence,
generate files with different sizes so that there is some property that
the swapped files can be discovered reliably even on Windows.

When c5c31d33 (grep: move pattern-type bits support to top-level
grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper
function, the intention was to allow the users of grep API to having
to fiddle only with .pattern_type_option (which can be set to "fixed",
"basic", "extended", and "pcre"), and then immediately before compiling
the pattern strings for use, call grep_commit_pattern_type() to have
it prepare various bits in the grep_opt structure (like .fixed,
.regflags, etc.).
However, grep_set_pattern_type_option() helper function the grep API
internally uses were left as an external function by mistake. This
function shouldn't have been made callable by the users of the API.
Later when the grep API was used in revision traversal machinery,
the caller then mistakenly started calling the function around
34a4ae55 (log --grep: use the same helper to set -E/-F options as
"git grep", 2012-10-03), instead of setting the .pattern_type_option
field and letting the grep_commit_pattern_type() to take care of the
details.
This caused an unnecessary bug that made a configured
grep.patternType take precedence over the command line options
(e.g. --basic-regexp, --fixed-strings) in "git log" family of
commands.

'git submodule--helper update-clone' has logic to retry failed clones
a second time. For this purpose, there is a list of submodules to clone,
and a second list that is filled with the submodules to retry. Within
these lists, the submodules are identified by an index as if both lists
were just appended.
This works nicely except when the second clone attempt fails as well. To
report an error, the identifying index must be adjusted by an offset so
that it can be used as an index into the second list. However, the
calculation uses the logical total length of the lists so that the result
always points one past the end of the second list.
Pick the correct index.

git-submodule--helper is invoked as the upstream of a pipe in several
places. Usually, the failure of a program in this position is not
detected by the shell. For this reason, the code inserts a token in the
output stream when git-submodule--helper fails that is detected
downstream, where the shell script is quit with exit code 1.
There happens to be a bug in git-submodule--helper that leads to a
segmentation fault. The test suite triggers the crash in several places,
all of which are protected by 'test_must_fail'. But due to the inspecific
exit code 1, the crash remains undiagnosed.
Extend the failure protocol such that git-submodule--helper's exit code
is passed downstream (only in the case of failure). This enables the
downstream to use it as its own exit code, and 'test_must_fail' to
identify the segmentation fault as an unexpected failure.
The bug itself is fixed in the next commit.

In the transport protocol we use NAK to signal the non existence of a
common base, so fix the documentation. This helps readers of the document,
as they don't have to wonder about the difference between NAK and NACK.
As NACK is used in git archive and upload-archive, this is easy to get
wrong.

There is an optimization used in "git diff $treeA $treeB" to borrow
an already checked-out copy in the working tree when it is known to
be the same as the blob being compared, expecting that open/mmap of
such a file is faster than reading it from the object store, which
involves inflating and applying delta. This however kicked in even
when the checked-out copy needs to go through the convert-to-git
conversion (including the clean filter), which defeats the whole
point of the optimization. The optimization has been disabled when
the conversion is necessary.

When accessing a blob for a diff, we may try to reuse file
contents in the working tree, under the theory that it is
faster to mmap those file contents than it would be to
extract the content from the object database.
When we have to filter those contents, though, that
assumption does not hold. Even for our internal conversions
like CRLF, we have to allocate and fill a new buffer anyway.
But much worse, for external clean filters we have to exec
an arbitrary script, and we have no idea how expensive it
may be to run.
So let's skip this optimization when conversion into git's
"clean" form is required. This applies whenever the
"want_file" flag is false. When it's true, the caller
actually wants the smudged worktree contents, which the
reused file by definition already has (in fact, this is a
key optimization going the other direction, since reusing
the worktree file there lets us skip smudge filters).

Commit 959b5455 (submodule: implement a config API for lookup of
.gitmodules values, 2015-08-18) implemented the initial version of the
submodule config cache. During development of that initial version we
extracted the function gitmodule_sha1_from_commit(). During that process
we missed that the strbuf rev was still used in config_from() and now is
left empty. Lets fix this by also returning this string.
This means that now when reading .gitmodules from revisions, the error
messages also contain a reference to the blob they are from.

After a client has sent us the complete pack, we may spend
some time processing the data and running hooks. If the
client asked us to be quiet, receive-pack won't send any
progress data during the index-pack or connectivity-check
steps. And hooks may or may not produce their own progress
output. In these cases, the network connection is totally
silent from both ends.
Git itself doesn't care about this (it will wait forever),
but other parts of the system (e.g., firewalls,
load-balancers, etc) might hang up the connection. So we'd
like to send some sort of keepalive to let the network and
the client side know that we're still alive and processing.
We can use the same trick we did in 05e9515 (upload-pack:
send keepalive packets during pack computation, 2013-09-08).
Namely, we will send an empty sideband data packet every `N`
seconds that we do not relay any stderr data over the
sideband channel. As with 05e9515, this means that we won't
bother sending keepalives when there's actual progress data,
but will kick in when it has been disabled (or if there is a
lull in the progress data).
The concept is simple, but the details are subtle enough
that they need discussing here.
Before the client sends us the pack, we don't want to do any
keepalives. We'll have sent our ref advertisement, and we're
waiting for them to send us the pack (and tell us that they
support sidebands at all).
While we're receiving the pack from the client (or waiting
for it to start), there's no need for keepalives; it's up to
them to keep the connection active by sending data.
Moreover, it would be wrong for us to do so. When we are the
server in the smart-http protocol, we must treat our
connection as half-duplex. So any keepalives we send while
receiving the pack would potentially be buffered by the
webserver. Not only does this make them useless (since they
would not be delivered in a timely manner), but it could
actually cause a deadlock if we fill up the buffer with
keepalives. (It wouldn't be wrong to send keepalives in this
phase for a full-duplex connection like ssh; it's simply
pointless, as it is the client's responsibility to speak).
As soon as we've gotten all of the pack data, then the
client is waiting for us to speak, and we should start
keepalives immediately. From here until the end of the
connection, we send one any time we are not otherwise
sending data.
But there's a catch. Receive-pack doesn't know the moment
we've gotten all the data. It passes the descriptor to
index-pack, who reads all of the data, and then starts
resolving the deltas. We have to communicate that back.
To make this work, we instruct the sideband muxer to enable
keepalives in three phases:
1. In the beginning, not at all.
2. While reading from index-pack, wait for a signal
indicating end-of-input, and then start them.
3. Afterwards, always.
The signal from index-pack in phase 2 has to come over the
stderr channel which the muxer is reading. We can't use an
extra pipe because the portable run-command interface only
gives us stderr and stdout.
Stdout is already used to pass the .keep filename back to
receive-pack. We could also send a signal there, but then we
would find out about it in the main thread. And the
keepalive needs to be done by the async muxer thread (since
it's the one writing sideband data back to the client). And
we can't reliably signal the async thread from the main
thread, because the async code sometimes uses threads and
sometimes uses forked processes.
Therefore the signal must come over the stderr channel,
where it may be interspersed with other random
human-readable messages from index-pack. This patch makes
the signal a single NUL byte. This is easy to parse, should
not appear in any normal stderr output, and we don't have to
worry about any timing issues (like seeing half the signal
bytes in one read(), and half in a subsequent one).
This is a bit ugly, but it's simple to code and should work
reliably.
Another option would be to stop using an async thread for
muxing entirely, and just poll() both stderr and stdout of
index-pack from the main thread. This would work for
index-pack (because we aren't doing anything useful in the
main thread while it runs anyway). But it would make the
connectivity check and the hook muxers much more
complicated, as they need to simultaneously feed the
sub-programs while reading their stderr.
The index-pack phase is the only one that needs this
signaling, so it could simply behave differently than the
other two. That would mean having two separate
implementations of copy_to_sideband (and the keepalive
code), though. And it still doesn't get rid of the
signaling; it just means we can write a nicer message like
"END_OF_INPUT" or something on stdout, since we don't have
to worry about separating it from the stderr cruft.
One final note: this signaling trick is only done with
index-pack, not with unpack-objects. There's no point in
doing it for the latter, because by definition it only kicks
in for a small number of objects, where keepalives are not
as useful (and this conveniently lets us avoid duplicating
the implementation).

When we receive a large push, the server side of the
connection may spend a lot of time (30s or more for a full
push of linux.git) walking the object graph without
producing any output. Let's give the user some indication
that we're actually working.

If the connectivity check encounters a problem when
receiving a push, the error output goes to receive-pack's
stderr, whose destination depends on the protocol used
(ssh tends to send it to the user, though without a "remote"
prefix; http will generally eat it in the server's error
log).
The information should consistently go back to the user, as
there is a reasonable chance their client is buggy and
generating a bad pack.
We can do so by muxing it over the sideband as we do with
other sub-process stderr.

When we receive a large push, the server side may have to
spend a lot of CPU processing the incoming packfile.
During the "receiving" phase, we are typically network
bound, and the client is writing its own progress to the
user. But during the delta resolution phase, we may spend
minutes (e.g., for a full push of linux.git) without
making any indication to the user that the connection has
not hung.
Let's ask index-pack to produce progress output for this
phase (unless the client asked us to be quiet, of course).

The index-pack command has two progress meters: one for
"receiving objects", and one for "resolving deltas". You get
neither by default, or both with "-v".
But for a push through receive-pack, we would want only the
"resolving deltas" phase, _not_ the "receiving objects"
progress. There are two reasons for this.
One is simply that existing clients are already printing
"writing objects" progress at the same time. Arguably
"receiving" from the far end is more useful, because it
tells you what has actually gotten there, as opposed to what
might be stuck in a buffer somewhere between the client and
server. But that would require a protocol extension to tell
clients not to print their progress. Possible, but
complexity for little gain.
The second reason is much more important. In a full-duplex
connection like git-over-ssh, we can print progress while
the pack is incoming, and it will immediately get to the
client. But for a half-duplex connection like git-over-http,
we should not say anything until we have received the full
request. Anything we write is subject to being stuck in a
buffer by the webserver. Worse, we can end up in a deadlock
if that buffer fills up.
So our best bet is to avoid writing anything that isn't a
small fixed size until we've received the full pack.

Because the initial connectivity check for a cloned
repository can be slow, 0781aa4 (clone: let the user know
when check_everything_connected is run, 2013-05-03) added a
"fake" progress meter; we simply say "Checking connectivity"
when it starts, and "done" at the end, with nothing between.
Since check_connected() now knows how to do a real progress
meter, we can drop our fake one and use that one instead.

Connectivity checks have to traverse the entire object graph
in the worst case (e.g., a full clone or a full push). For
large repositories like linux.git, this can take 30-60
seconds, during which time git may produce little or no
output.
Let's add the option of showing progress, which is taken
care of by rev-list.

Unless the "quiet" flag is given, check_connected sends any
errors to the stderr of the caller (because the child
rev-list inherits that descriptor). However, server-side
callers may want to send these over a sideband channel
instead. Let's make that possible.

The number of variants of check_everything_connected has
grown over the years, so that the "real" function takes
several possibly-zero, possibly-NULL arguments. We hid the
complexity behind some wrapper functions, but this doesn't
scale well when we want to add new options.
If we add more wrapper variants to handle the new options,
then we can get a combinatorial explosion when those options
might be used together (right now nobody wants to use both
"shallow" and "transport" together, so we get by with just a
few wrappers).
If instead we add new parameters to each function, each of
which can have a default value, then callers who want the
defaults end up with confusing invocations like:
check_everything_connected(fn, 0, data, -1, 0, NULL);
where it is unclear which parameter is which (and every
caller needs updated when we add new options).
Instead, let's add a struct to hold all of the optional
parameters. This is a little more verbose for the callers
(who have to declare the struct and fill it in), but it
makes their code much easier to follow, because every option
is named as it is set (and unused options do not have to be
mentioned at all).
Note that we could also stick the iteration function and its
callback data into the option struct, too. But since those
are required for each call, by avoiding doing so, we can let
very simple callers just pass "NULL" for the options and not
worry about the struct at all.
While we're touching each site, let's also rename the
function to check_connected(). The existing name was quite
long, and not all of the wrappers even used the full name.

It's easy to ask rev-list to do a traversal that may takes
many seconds (e.g., by calling "--objects --all"). In theory
you can monitor its progress by the output you get to
stdout, but this isn't always easy.
Some operations, like "--count", don't make any output until
the end.
And some callers, like check_everything_connected(), are
using it just for the error-checking of the traversal, and
throw away stdout entirely.
This patch adds a "--progress" option which can be used to
give some eye-candy for a user waiting for a long traversal.
This is just a rev-list option and not a regular traversal
option, because it needs cooperation from the callbacks in
builtin/rev-list.c to do the actual count.

The check_everything_connected function takes a "quiet"
parameter which does two things if non-zero:
1. redirect rev-list's stderr to /dev/null to avoid
showing errors to the user
2. pass "--quiet" to rev-list
Item (1) is obviously useful. But item (2) is
surprisingly not. For rev-list, "--quiet" does not have
anything to do with chattiness on stderr; it tells rev-list
not to bother writing the list of traversed objects to
stdout, for efficiency. And since we always redirect
rev-list's stdout to /dev/null in this function, there is no
point in asking it to ever write anything to stdout.
The efficiency gains are modest; a best-of-five run of "git
rev-list --objects --all" on linux.git dropped from 32.013s
to 30.502s when adding "--quiet". That's only about 5%, but
given how easy it is, it's worth doing.

"git fetch" exchanges batched have/ack messages between the sender
and the receiver, initially doubling every time and then falling
back to enlarge the window size linearly. The "smart http"
transport, being an half-duplex protocol, outgrows the preset limit
too quickly and becomes inefficient when interacting with a large
repository. The internal mechanism learned to grow the window size
more aggressively when working with the "smart http" transport.

When updating large repositories, the LARGE_FLUSH limit (that is, the
limit at which the window growth strategy switches from exponential to
linear) is reached quite quickly. Use a conservative exponential growth
strategy when that limit is reached instead (and increase LARGE_FLUSH so
that there is no regression in window size).
This optimization is only applied during stateless RPCs to avoid the
issue raised and fixed in commit 44d8dc54 (Fix potential local
deadlock during fetch-pack, 2011-03-29).

If you have whitespace errors in lines you've introduced, it
can be convenient to be able to jump directly to them for
fixing. You can't quite use "git jump diff" for this,
because though it passes arbitrary options to "git diff", it
expects to see an actual unified diff in the output.
Whereas "git diff --check" actually produces lines that look
like compiler quickfix lines already, meaning we just need
to run it and feed the output directly to the editor.

The hunk-header regex looks for "\+\d+" to find the
post-image line numbers, but it skips the pre-image line
numbers with a simple ".*". That means we may greedily eat
the post-image numbers and match a "\+\d" further on, in the
funcname text.
For example, commit 6b9c38e has this hunk header:
diff --git a/t/t0006-date.sh b/t/t0006-date.sh
[...]
@@ -50,8 +50,8 @@ check_show iso-local "$TIME" '2016-06-15 14:13:20 +0000'
If you run:
git checkout 6b9c38e
git jump diff HEAD^ t/
it will erroneously match "+0000" as the starting line
number and jump there, rather than line 50.
We can fix it by just making the "skip" regex non-greedy,
taking the first "+" we see, which should be the post-image
line information.
