When sending patch series (with a cover-letter or not)
sendemail-validate is called with every email/patch file independently
from the others. When one of the patches depends on a previous one, it
may not be possible to use this hook in a meaningful way. A hook that
wants to check some property of the whole series needs to know which
patch is the final one.
Expose the current and total number of patches to the hook via the
GIT_SENDEMAIL_PATCH_COUNTER and GIT_SENDEMAIL_PATCH_TOTAL environment
variables so that both incremental and global validation is possible.
Sharing any other state between successive invocations of the validate
hook must be done via external means. For example, by storing it in
a git config sendemail.validateWorktree entry.
Add a sample script with placeholder validations and update tests to
check that the counters are properly exported.

The $(QUIET) variables we define are largely duplicated between our
various Makefiles, let's define them in the new "shared.mak" instead.
Since we're not using the environment to pass these around we don't
need to export the "QUIET_GEN" and "QUIET_BUILT_IN" variables
anymore. The "QUIET_GEN" variable is used in "git-gui/Makefile" and
"gitweb/Makefile", but they've got their own definition for those. The
"QUIET_BUILT_IN" variable is only used in the top-level "Makefile". We
still need to export the "V" variable.

We have various behavior that's shared across our Makefiles, or that
really should be (e.g. via defined templates). Let's create a
top-level "shared.mak" to house those sorts of things, and start by
adding the ".DELETE_ON_ERROR" flag to it.
See my own 7b76d6bf22 (Makefile: add and use the ".DELETE_ON_ERROR"
flag, 2021-06-29) and db10fc6c09 (doc: simplify Makefile using
.DELETE_ON_ERROR, 2021-05-21) for the addition and use of the
".DELETE_ON_ERROR" flag.
I.e. this changes the behavior of existing rules in the altered
Makefiles (except "Makefile" & "Documentation/Makefile"). I'm
confident that this is safe having read the relevant rules in those
Makfiles, and as the GNU make manual notes that it isn't the default
behavior is out of an abundance of backwards compatibility
caution. From edition 0.75 of its manual, covering GNU make 4.3:
[Enabling '.DELETE_ON_ERROR' is] almost always what you want
'make' to do, but it is not historical practice; so for
compatibility, you must explicitly request it.
This doesn't introduce a bug by e.g. having this
".DELETE_ON_ERROR" flag only apply to this new shared.mak, Makefiles
have no such scoping semantics.
It does increase the danger that any Makefile without an explicit "The
default target of this Makefile is..." snippet to define the default
target as "all" could have its default rule changed if our new
shared.mak ever defines a "real" rule. In subsequent commits we'll be
careful not to do that, and such breakage would be obvious e.g. in the
case of "make -C t".
We might want to make that less fragile still (e.g. by using
".DEFAULT_GOAL" as noted in the preceding commit), but for now let's
simply include "shared.mak" without adding that boilerplate to all the
Makefiles that don't have it already. Most of those are already
exposed to that potential caveat e.g. due to including "config.mak*".

The watchman integration for fsmonitor was racy, which has been
corrected to be more conservative.
* kw/fsmonitor-watchman-fix:
fsmonitor: fix watchman integration
When running Git commands quickly -- such as in a shell script or the
test suite -- the Git commands frequently complete and start again
during the same second. The example fsmonitor hooks to integrate with
Watchman truncate the nanosecond times to seconds. In principle, this is
fine, as Watchman claims to use inclusive comparisons [1]. The result
should only be an over-representation of the changed paths since the
last Git command.
However, Watchman's own documentation claims "Using a timestamp is prone
to race conditions in understanding the complete state of the file tree"
[2]. All of their documented examples use a "clockspec" that looks like
'c:123:234'. Git should eventually learn how to store this type of
string to provide a stronger integration, but that will be a more
invasive change.
When using GIT_TEST_FSMONITOR="$(pwd)/t7519/fsmonitor-watchman", scripts
such as t7519-wtstatus.sh fail due to these race conditions. In fact,
running any test script with GIT_TEST_FSMONITOR pointing at
t/t7519/fsmonitor-wathcman will cause failures in the test_commit
function. The 'git add "$indir$file"' command fails due to not enough
time between the creation of '$file' and the 'git add' command.
For now, subtract one second from the timestamp we pass to Watchman.
This will make our window large enough to avoid these race conditions.
Increasing the window causes tests like t7519-wtstatus.sh to pass.
When the integration was introduced in def437671 (fsmonitor: add a
sample integration script for Watchman, 2018-09-22), the query included
an expression that would ignore files created and deleted in that
window. The performance reason for this change was to ignore temporary
files created by a build between Git commands. However, this causes
failures in script scenarios where Git is creating or deleting files
quickly.
When using GIT_TEST_FSMONITOR as before, t2203-add-intent.sh fails
due to this add-and-delete race condition.
By removing the "expression" from the Watchman query, we remove this
race condition. It will lead to some performance degradation in the case
of users creating and deleting temporary files inside their working
directory between Git commands. However, that is a cost we need to pay
to be correct.

In Perl, setting $/ sets the string that is used as the "record
separator," which sets the boundary that the `<>` construct reads to.
Setting `local $/ = 0666;` evaluates the octal, getting 438, and
stringifies it. Thus, the later read from `<CHLD_OUT>` stops as soon
as it encounters the string "438" in the watchman output, yielding
invalid JSON; repositories containing filenames with SHA1 hashes are
able to trip this easily.
Set `$/` to undefined, thus slurping all output from watchman. Also
close STDIN which is provided to watchman, to better guarantee that we
cannot deadlock with watchman while both attempting to read.

The environment variable GIT_PUSH_OPTION_COUNT is set to the number of
push options sent, and GIT_PUSH_OPTION_{0,1,..} is set to the transmitted
option.
The code is not executed as the push options are set to NULL, nor is the
new capability advertised.
There was some discussion back and forth how to present these push options
to the user as there are some ways to do it:
Keep all options in one environment variable
============================================
+ easiest way to implement in Git
- This would make things hard to parse correctly in the hook.
Put the options in files instead,
filenames are in GIT_PUSH_OPTION_FILES
======================================
+ After a discussion about environment variables and shells, we may not
want to put user data into an environment variable (see [1] for example).
+ We could transmit binaries, i.e. we're not bound to C strings as
we are when using environment variables to the user.
+ Maybe easier to parse than constructing environment variable names
GIT_PUSH_OPTION_{0,1,..} yourself
- cleanup of the temporary files is hard to do reliably
- we have race conditions with multiple clients pushing, hence we'd need
to use mkstemp. That's not too bad, but still.
Use environment variables, but restrict to key/value pairs
==========================================================
(When the user pushes a push option `foo=bar`, we'd
GIT_PUSH_OPTION_foo=bar)
+ very easy to parse for a simple model of push options
- it's not sufficient for more elaborate models, e.g.
it doesn't allow doubles (e.g. cc=reviewer@email)
Present the options in different environment variables
======================================================
(This is implemented)
* harder to parse as a user, but we have a sample hook for that.
- doesn't allow binary files
+ allows the same option twice, i.e. is not restrictive about
options, except for binary files.
+ doesn't clutter a remote directory with (possibly stale)
temporary files
As we first want to focus on getting simple strings to work
reliably, we go with the last option for now. If we want to
do transmission of binaries later, we can just attach a
'side-channel', e.g. "any push option that contains a '\0' is
put into a file instead of the environment variable and we'd
have new GIT_PUSH_OPTION_FILES, GIT_PUSH_OPTION_FILENAME_{0,1,..}
environment variables".

the "read" used in the per-ref while loop that iterates over
"<localref> SP <localsha1> SP <remoteref> SP <remotesha>" records,
where we know refs and sha1s will not have SPs, would split them
correctly.
While this is not wrong per-se, it is not necessary; because we know
these fields do not contain HT or LF, either, we can simply leave
IFS the default.
This will also prevent those who cut and paste from this sample from
getting bitten when they write things in the per-ref loop that need
splitting with the default $IFS (e.g. use $(git rev-list ...) to
produce one-record-per-line output).
