We used to unconditionally disable the pager in the pager process
we spawn to feed out output, but that prevented people who want to
run "less" within "less" from doing so.
* je/pager-do-not-recurse:
pager: do allow spawning pager recursively
Since the very beginning of Git, we gave the LESS environment a
default value "FRSX" when we spawn "less" as the pager. "S" (chop
long lines instead of wrapping) has been removed from this default
set of options, because it is more or less a personal taste thing,
as opposed to others that have good justifications (i.e. "R" is very
much justified because many kinds of output we produce are colored
and "FX" is justified because output we produce is often shorter
than a page).
Existing users who prefer not to see line-wrapped output may want to
set
$ git config core.pager "less -S"
to restore the traditional behaviour. It is expected that people
find output from the most subcommands easier to read with the new
default, except for "blame" which tends to produce really long
lines. To override the new default only for "git blame", you can do
this:
$ git config pager.blame "less -S"
* mm/pager-less-sans-S:
pager: remove 'S' from $LESS by default
update-index: fix segfault with missing --cacheinfo argument
Running "git update-index --cacheinfo" without any further
arguments results in a segfault rather than an error
message. Commit ec160ae (update-index: teach --cacheinfo a
new syntax "mode,sha1,path", 2014-03-23) added code to
examine the format of the argument, but forgot to handle the
NULL case.
Returning an error from the parser is enough, since we then
treat it as an old-style "--cacheinfo <mode> <sha1> <path>",
and complain that we have less than 3 arguments to read.

mergetool.prompt used to default to 'true', always causing a confirmation
"do you really want to run the tool on this path" to be shown.
Among the two purposes the prompt serves, ignore the use case to
confirm that the user wants to view particular path with the named
tool, and make the prompt only to confirm the choice of the tool
made by autodetection and defaulting. For those who configured the
tool explicitly, the prompt shown for the latter purpose is simply
annoying.
Strictly speaking, this is a backward incompatible change and the
users need to explicitly set the variable to 'true' if they want to
resurrect the now-ignored use case.

Read-only operations such as "git status" that internally refreshes
the index write out the refreshed index to the disk to optimize
future accesses to the working tree, but this could race with a
"read-write" operation that modify the index while it is running.
Detect such a race and avoid overwriting the index.
Duy raised a good point that we may need to do the same for the
normal writeout codepath, not just the "opportunistic" update
codepath. While that is true, nobody sane would be running two
simultaneous operations that are clearly write-oriented competing
with each other against the same index file. So in that sense that
can be done as a less urgent follow-up for this topic.

Instead of running N pair-wise diff-trees when inspecting a

As 0232852b, but for the push tests instead: this avoids a start_httpd
in the middle of the file, which fails under GIT_TEST_HTTPD=false.
Note that we have to munge the test in a few ways while
moving it:
1. We drop the `test -z "$GIT_TEST_HTTPD"` check; this is
too simplistic since 83d842d, and we should let
lib-httpd.sh handle it.
2. We have to port over some of the old setup from t5538.
3. In the final test, we no longer expect the extra commit
"1" built on top of "4". This was a side effect from an
earlier test in t5538 which was not ported over.

These were originally removed by 0232852 (t5537: move
http tests out to t5539, 2014-02-13). However, they were
accidentally re-added in 1ddb4d7 (Merge branch
'nd/upload-pack-shallow', 2014-03-21).
This looks like an error in manual conflict resolution.
Here's what happened:
1. v1.9.0 shipped with the http tests in t5537.
2. We realized that this caused problems, and built 0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.
3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.
When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

git-p4: Do not include diff in spec file when just preparing p4
The diff information render the spec file unusable as is by p4,
do not include it when run with --prepare-p4-only so that the
given file can be directly passed to p4.
With --prepare-p4-only, git-p4 already tells the user it can use
p4 submit with the generated spec file. This fails because of the
diff being present in the file. Not including the diff fixes that.
Without --prepare-p4-only, keeping the diff makes sense for a
quick review of the patch before submitting it. And does not cause
problems with p4 as we remove it programmatically.

test-lint: find unportable sed, echo, test, and export usage after &&
Instead of anchoring these checks with "^\s*", just check that the
usage is preceded by a word boundary. So now we can catch
test $cond && export foo=bar
just like we already catch
test $cond &&
export foo=bar
As a side effect, this will detect usage of "sed -i", "echo -n", "test
a == b", and "export a=b" in comments. That is not ideal but it's
potentially useful because people sometimes copy code from comments so
it can be good to also avoid nonportable patterns there.
To avoid false positives, keep the checks for 'declare' and 'which'
anchored. Those are frequently used words in normal English-language
comments.

Instead of showing a warning and working as before, fail and show
the message and force immediate upgrade from their upstream
repositories when these tools are run, per request from their
primary author.
The construct is error-prone; "test" being built-in in most modern
shells, the reason to avoid "test <cond> && test <cond>" spawning
one extra process by using a single "test <cond> -a <cond>" no
longer exists.
The author of the original topic says he broke the upcoming 2.0
release with something that relates to "synchronization crash
regression" while refusing to give further specifics, so this would
unfortunately be the safest option for the upcoming release.
git-prompt.sh: don't assume the shell expands the value of PS1
Not all shells subject the prompt string to parameter expansion. Test
whether the shell will expand the value of PS1, and use the result to
control whether raw ref names are included directly in PS1.
This fixes a regression introduced in commit 8976500 ("git-prompt.sh:
don't put unsanitized branch names in $PS1"): zsh does not expand PS1
by default, but that commit assumed it did. The bug resulted in
prompts containing the literal string '${__git_ps1_branch_name}'
instead of the actual branch name.

commit: allow core.commentChar=auto for character auto selection
When core.commentChar is "auto", the comment char starts with '#' as
in default but if it's already in the prepared message, find another
char in a small subset. This should stop surprises because git strips
some lines unexpectedly.
Note that git is not smart enough to recognize '#' as the comment char
in custom templates and convert it if the final comment char is
different. It thinks '#' lines in custom templates as part of the
commit message. So don't use this with custom templates.

that behavior is wanted.

git-gui: tolerate major version changes when comparing the git version
Since git 2.0.0 starting git gui in a submodule using a gitfile fails with
the following error:
No working directory ../../../<path>
couldn't change working directory
to "../../../<path>": no such file or
directory
This is because "git rev-parse --show-toplevel" is only run when git gui
sees a git version of at least 1.7.0 (which is the version in which the
--show-toplevel option was introduced). But "package vsatisfies" returns
false when the major version changes, which is not what we want here.
Fix that for both places where the git version is checked using vsatisfies
by appending a '-' to the version number. This tells vsatisfies that a
change of the major version is not considered to be a problem, as long as
the new major version is larger. This is done for both the place that
caused the reported bug and another spot where the git version is tested
for another feature.
