e904deb89d submodule: reject submodule.update = !command in .gitmodules
Since ac1fbbda20 (submodule: do not copy unknown update mode from
.gitmodules, 2013-12-02), Git has been careful to avoid copying

	[submodule "foo"]
		update = !run an arbitrary scary command

from .gitmodules to a repository's local config, copying in the
setting 'update = none' instead.  The gitmodules(5) manpage documents
the intention:

	The !command form is intentionally ignored here for security
	reasons

Unfortunately, starting with v2.20.0-rc0 (which integrated ee69b2a9
(submodule--helper: introduce new update-module-mode helper,
2018-08-13, first released in v2.20.0-rc0)), there are scenarios where
we *don't* ignore it: if the config store contains no
submodule.foo.update setting, the submodule-config API falls back to
reading .gitmodules and the repository-supplied !command gets run
after all.

This was part of a general change over time in submodule support to
read more directly from .gitmodules, since unlike .git/config it
allows a project to change values between branches and over time
(while still allowing .git/config to override things).  But it was
never intended to apply to this kind of dangerous configuration.

The behavior change was not advertised in ee69b2a9's commit message
and was missed in review.

Let's take the opportunity to make the protection more robust, even in
Git versions that are technically not affected: instead of quietly
converting 'update = !command' to 'update = none', noisily treat it as
an error.  Allowing the setting but treating it as meaning something
else was just confusing; users are better served by seeing the error
sooner.  Forbidding the construct makes the semantics simpler and
means we can check for it in fsck (in a separate patch).

As a result, the submodule-config API cannot read this value from
.gitmodules under any circumstance, and we can declare with confidence

	For security reasons, the '!command' form is not accepted
	here.

The only references to Gmane that remain are in RelNotes. Although these
are definitely not in active use, they might be of historical interest
for future readers so let's ensure that mail references are more robust.

Replace links to Gmane with links to lore.kernel.org (which is our new
preferred mailing list archive and has the Message-ID in the URL) and
bare Gmane ID references with Message-IDs.

The Message-IDs were found by searching for "gmane:<id>" on
https://public-inbox.org/git/ and taking the resulting message.

a9aecc7abb checkout, restore: support the --pathspec-from-file option
Decisions taken for simplicity:
1) For now, `--pathspec-from-file` is declared incompatible with
   `--patch`, even when <file> is not `stdin`. Such use case it not
   really expected.
2) It is not allowed to pass pathspec in both args and file.

`you must specify path(s) to restore` block was moved down to be able to
test for `pathspec.nr` instead, because testing for `argc` is no longer
correct.

`git switch` does not support the new options because it doesn't expect
`<pathspec>` arguments.

It was added in [1]. I understand that the duplicate change was not

Also, in explanation, there was only one section for two synopsis
entries.

Fix both problems by removing duplicate synopsis.

<paths> vs <pathspec> is resolved in next patch.

a52ed76142 fast-import: disallow "feature import-marks" by default
As with export-marks in the previous commit, import-marks can access the
filesystem. This is significantly less dangerous than export-marks
because it only involves reading from arbitrary paths, rather than
writing them. However, it could still be surprising and have security
implications (e.g., exfiltrating data from a service that accepts
fast-import streams).

Let's lump it (and its "if-exists" counterpart) in with export-marks,
and enable the in-stream version only if --allow-unsafe-features is set.

68061e3470 fast-import: disallow "feature export-marks" by default
The fast-import stream command "feature export-marks=<path>" lets the
stream write marks to an arbitrary path. This may be surprising if you
are running fast-import against an untrusted input (which otherwise
cannot do anything except update Git objects and refs).

Let's disallow the use of this feature by default, and provide a
command-line option to re-enable it (you can always just use the
command-line --export-marks as well, but the in-stream version provides
an easy way for exporters to control the process).

This is a backwards-incompatible change, since the default is flipping
to the new, safer behavior. However, since the main users of the
in-stream versions would be import/export-based remote helpers, and
since we trust remote helpers already (which are already running
arbitrary code), we'll pass the new option by default when reading a
remote helper's stream. This should minimize the impact.

Note that the implementation isn't totally simple, as we have to work
around the fact that fast-import doesn't parse its command-line options
until after it has read any "feature" lines from the stream. This is how
it lets command-line options override in-stream. But in our case, it's
important to parse the new --allow-unsafe-features first.

There are three options for resolving this:

  1. Do a separate "early" pass over the options. This is easy for us to
     do because there are no command-line options that allow the
     "unstuck" form (so there's no chance of us mistaking an argument
     for an option), though it does introduce a risk of incorrect
     parsing later (e.g,. if we convert to parse-options).

  2. Move the option parsing phase back to the start of the program, but
     teach the stream-reading code never to override an existing value.
     This is tricky, because stream "feature" lines override each other
     (meaning we'd have to start tracking the source for every option).

  3. Accept that we might parse a "feature export-marks" line that is
     forbidden, as long we don't _act_ on it until after we've parsed
     the command line options.

     This would, in fact, work with the current code, but only because
     the previous patch fixed the export-marks parser to avoid touching
     the filesystem.

     So while it works, it does carry risk of somebody getting it wrong
     in the future in a rather subtle and unsafe way.

I've gone with option (1) here as simple, safe, and unlikely to cause
regressions.

This fixes CVE-2019-1348.

4f3e57ef13 submodule--helper: advise on fatal alternate error
When recursively cloning a superproject with some shallow modules
defined in its .gitmodules, then recloning with "--reference=<path>", an
error occurs. For example:

  git clone --recurse-submodules --branch=master -j8 \
    https://android.googlesource.com/platform/superproject \
    master
  git clone --recurse-submodules --branch=master -j8 \
    https://android.googlesource.com/platform/superproject \
    --reference master master2

fails with:

  fatal: submodule '<snip>' cannot add alternate: reference repository
  '<snip>' is shallow

When a alternate computed from the superproject's alternate cannot be
added, whether in this case or another, advise about configuring the
"submodule.alternateErrorStrategy" configuration option and using
"--reference-if-able" instead of "--reference" when cloning.

10c64a0b3c Doc: explain submodule.alternateErrorStrategy
Commit 31224cbdc7 ("clone: recursive and reference option triggers
submodule alternates", 2016-08-17) taught Git to support the
configuration options "submodule.alternateLocation" and
"submodule.alternateErrorStrategy" on a superproject.

If "submodule.alternateLocation" is configured to "superproject" on a
superproject, whenever a submodule of that superproject is cloned, it
instead computes the analogous alternate path for that submodule from
$GIT_DIR/objects/info/alternates of the superproject, and references it.

The "submodule.alternateErrorStrategy" option determines what happens
if that alternate cannot be referenced. However, it is not clear that
the clone proceeds as if no alternate was specified when that option is
not set to "die" (as can be seen in the tests in 31224cbdc7). Therefore,
document it accordingly.

99dfa6f970 sparse-checkout: use in-process update for disable subcommand
The 'git sparse-checkout disable' subcommand returns a user to a
full working directory. The old process for doing this required
updating the sparse-checkout file with the "/*" pattern and then
updating the working directory with core.sparseCheckout enabled.
Finally, the sparse-checkout file could be removed and the config
setting disabled.

However, it is valuable to keep a user's sparse-checkout file
intact so they can re-enable the sparse-checkout they previously
used with 'git sparse-checkout init'. This is now possible with
the in-process mechanism for updating the working directory.

d89f09c828 clone: add --sparse mode
When someone wants to clone a large repository, but plans to work
using a sparse-checkout file, they either need to do a full
checkout first and then reduce the patterns they included, or
clone with --no-checkout, set up their patterns, and then run
a checkout manually. This requires knowing a lot about the repo
shape and how sparse-checkout works.

Add a new '--sparse' option to 'git clone' that initializes the
sparse-checkout file to include the following patterns:

	/*
	!/*/

These patterns include every file in the root directory, but
no directories. This allows a repo to include files like a
README or a bootstrapping script to grow enlistments from that
point.

During the 'git sparse-checkout init' call, we must first look
to see if HEAD is valid, since 'git clone' does not have a valid
HEAD at the point where it initializes the sparse-checkout. The
following checkout within the clone command will create the HEAD
ref and update the working directory correctly.

only documentation is supplementary information in the docs for

feature by creating a new 'git sparse-checkout' builtin. This
builtin will be the preferred mechanism for manipulating the
sparse-checkout file and syncing the working directory.

The documentation provided is adapted from the "git read-tree"

Extra sections are added to hint toward a future change to
a more restricted pattern set.

26d94853f0 pretty-options.txt: --notes accepts a ref instead of treeish
Although `--notes=` accepts and handles a tree-ish just fine, it isn't a
common use-case for users to pass in bare trees. By having "treeish", it
makes it harder to click in users' minds that the argument here is the
same type as the `notes.displayRef` configuration variable, for example.

Change `treeish` to `ref` so that it will be easier for users to make
this connection.

Note that we don't completely lose the notion that `--notes=` can accept
a tree-ish. In git-notes.txt, we have

	It is also permitted for a notes ref to point directly to a tree
	object, in which case the history of the notes can be read with
	`git log -p -g <refname>`.

which means that a hardcore user who wants to take advantage of this
obscure use-case will be able to infer the connection and not be
completely left in the dark.

1f0fc1db85 pretty: implement 'reference' format
The standard format for referencing other commits within some projects
(such as git.git) is the reference format. This is described in
Documentation/SubmittingPatches as

	If you want to reference a previous commit in the history of a stable
	branch, use the format "abbreviated hash (subject, date)", like this:

	....
		Commit f86a374 (pack-bitmap.c: fix a memleak, 2015-03-30)
		noticed that ...
	....

Since this format is so commonly used, standardize it as a pretty
format.

The tests that are implemented essentially show that the format-string
does not change in response to various log options. This is useful
because, for future developers, it shows that we've considered the
limitations of the "canned format-string" approach and we are fine with
them.

fb2ffa77a6 SubmittingPatches: remove dq from commit reference
Quoting SZEDER Gábor[1],

	SubmittingPatches is simply wrong: our de-facto standard format for
	referencing other commits does not enclose the subject in a pair of
	double-quotes:

	  $ git log v2.24.0 |grep -E '[0-9a-f]{7} \("' |wc -l
	  785
	  $ git log v2.24.0 |grep -E '[0-9a-f]{7} \([^"]' |wc -l
	  2276

	Those double-quotes don't add any value to the references, but they
	result in weird looking references for 1083 of our commits whose
	subject lines happen to end with double-quotes, e.g.:

	  f23a465132 ("hashmap_get{,_from_hash} return "struct hashmap_entry *"", 2019-10-06)

	and without those unnecessary pair of double-quotes we would have
	~3000 more commits whose summary would fit on a single line.

Remove references to the enclosing double-quotes from SubmittingPatches
since our de-facto standard for referencing commits does not actually
use them.

e440fc5888 commit: support the --pathspec-from-file option
Decisions taken for simplicity:
1) For now, `--pathspec-from-file` is declared incompatible with
   `--interactive/--patch`, even when <file> is not `stdin`. Such use
   case it not really expected. Also, it would require changes to
   `interactive_add()`.
2) It is not allowed to pass pathspec in both args and file.

2d92ab32fd rev-parse: make --show-toplevel without a worktree an error
Ever since it was introduced in 7cceca5ccc (Add 'git rev-parse
--show-toplevel' option., 2010-01-12), the --show-toplevel option has
treated a missing working tree as a quiet success: it neither prints a
toplevel path, but nor does it report any kind of error.

While a caller could distinguish this case by looking for an empty
response, the behavior is rather confusing. We're better off complaining
that there is no working tree, as other internal commands would do in
similar cases (e.g., "git status" or any builtin with NEED_WORK_TREE set
would just die()). So let's do the same here.

While we're at it, let's clarify the documentation and add some tests,
both for the new behavior and for the more mundane case (which was not
covered).

f83dff60a7 Start to implement a built-in version of git add --interactive
Unlike previous conversions to C, where we started with a built-in
helper, we start this conversion by adding an interception in the
`run_add_interactive()` function when the new opt-in
`add.interactive.useBuiltin` config knob is turned on (or the
corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and
calling the new internal API function `run_add_i()` that is implemented
directly in libgit.a.

At this point, the built-in version of `git add -i` only states that it
cannot do anything yet. In subsequent patches/patch series, the
`run_add_i()` function will gain more and more functionality, until it
is feature complete. The whole arc of the conversion can be found in the
PRs #170-175 at https://github.com/gitgitgadget/git.

The "--helper approach" can unfortunately not be used here: on Windows
we face the very specific problem that a `system()` call in
Perl seems to close `stdin` in the parent process when the spawned
process consumes even one character from `stdin`. Which prevents us from
implementing the main loop in C and still trying to hand off to the Perl
script.

The very real downside of the approach we have to take here is that the
test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the
conversion is complete (the `--helper` approach would have let it pass,
even at each of the incremental conversion steps).

git-shortlog, like git-log, supports options to filter what commits are
used to generate the log. These options come from git-rev-list, and are
documented in Documentation/rev-list-options.txt. Include those options
in shortlog's documentation.

But since rev-list-options.txt contains some other options that don't
really apply in the context of shortlog (like diff formatting, commit
ordering, etc), add a switch in rev-list-options.txt that excludes those
sections from the shortlog documentation. To be more specific, include
only the "Commit Limiting" and "History Simplification" sections.

3c8d754c4b myfirstcontrib: hint to find gitgitgadget allower
GitGitGadget, a handy tool for converting pull requests against Git into
Git-mailing-list-friendly-patch-emails, requires as anti-spam that all
new users be "/allow"ed by an existing user once before it will do
anything for that new user. While this tutorial explained that
mechanism, it did not give much hint on how to go about finding someone
to allow your new pull request. So, teach our new GitGitGadget user
where to look for someone who can add their name to the list.

The advice in this patch is based on the advice proposed for
GitGitGadget: https://github.com/gitgitgadget/gitgitgadget/pull/138

Users can discover commands and their brief usage by running 'git help
git' or 'git help -a'; both of these pages list all available commands
based on the contents of 'command-list.txt'. That means adding a new
command there is an important part of the new command process, and
therefore belongs in the new command tutorial.

Teach new users how to add their command, and include a brief overview
of how to discover which attributes to place on the command in the list.

Since 'git psuh' prints some workspace info, doesn't modify anything,
and is targeted as a user-facing porcelain command, list it as a
'mainporcelain' and 'info' command.

As the usage string is required to generate this documentation, don't
add the command to the list until after the usage string is added to the
tutorial.

8dfb04ae96 update-index: optionally leave skip-worktree entries alone
While `git update-index` mostly ignores paths referring to index entries
whose skip-worktree bit is set, in b4d1690df1 (Teach Git to respect
skip-worktree bit (reading part), 2009-08-20), for reasons that are not
entirely obvious, the `--remove` option was made special: it _does_
remove index entries even if their skip-worktree bit is set.

Seeing as this behavior has been in place for a decade now, it does not
make sense to change it.

However, in preparation for fixing a bug in `git stash` where it
pretends that skip-worktree entries have actually been removed, we need
a mode where `git update-index` leaves all skip-worktree entries alone,
even if the `--remove` option was passed.

55aca515eb manpage-bold-literal.xsl: match for namespaced "d:literal" in template
We recently regressed our rendering with Asciidoctor of "literal"
elements in our manpages, i.e, stuff we have placed within `backticks`
in order to render as monospace. In particular, we lost the bold
rendering of such literal text.

The culprit is f6461b82b9 ("Documentation: fix build with Asciidoctor 2",
2019-09-15), where we switched from DocBook 4.5 to DocBook 5 with
Asciidoctor. As part of the switch, we started using the namespaced
DocBook XSLT stylesheets rather than the non-namespaced ones. (See
f6461b82b9 for more details on why we changed to the namespaced ones.)

The bold literals are implemented as an XSLT snippet <xsl:template
match="literal">...</xsl:template>. Now that we use namespaces, this
doesn't pick up our literals like it used to.

Match for "d:literal" in addition to just "literal", after defining the
d namespace. ("d" is what
http://docbook.sourceforge.net/release/xsl-ns/current/manpages/docbook.xsl
uses.) Note that we need to keep matching without the namespace for
AsciiDoc.

This boldness was introduced by 5121a6d993 ("Documentation: option to
render literal text as bold for manpages", 2009-03-27) and made the
default in 5945717009 ("Documentation: bold literals in man",
2016-05-31).

One reason this was not caught in review is that our doc-diff tool diffs
without any boldness, i.e., it "only" compares text. As pointed out by
Peff in review of this patch, one can use `MAN_KEEP_FORMATTING=1
./doc-diff <...>`

This has been optically tested with AsciiDoc 8.6.10, Asciidoctor 1.5.5
and Asciidoctor 2.0.10. I've also verified that doc-diff produces the
empty output for all three programs, as expected, and that with the
MAN_KEEP_FORMATTING trick, AsciiDoc yields no diff, whereas with
Asciidoctor, we get bold literals, just like we want.

0115e5d929 git-diff.txt: document return code of --no-index
Within diff_no_index(), we have the following:

	revs->diffopt.flags.exit_with_status = 1;

	...

	/*
	 * The return code for --no-index imitates diff(1):
	 * 0 = no changes, 1 = changes, else error
	 */
	return diff_result_code(&revs->diffopt, 0);

Which means when `git diff` is run in `--no-index` mode, `--exit-code`
is implied. However, the documentation for this is missing in
git-diff.txt.

Add a note about how `--exit-code` is implied in the `--no-index`
documentation to cover this documentation blindspot.

In many projects the number of contributors is low enough that users know

Displaying only the author's username saves a lot of columns on the screen.

Existing 'e/E' (as in "%ae" and "%aE") placeholders would show the
author's address as "prarit@redhat.com", which would waste columns to show
the same domain-part for all contributors when used in a project internal
to redhat.  Introduce 'l/L' placeholders that strip '@' and domain part from

8dd327b246 Documentation/git-bisect.txt: add --no-ff to merge command
The hotfix application example uses `git merge --no-commit` to apply
temporary changes to the working tree during a bisect operation. In some
situations this can be a fast-forward and `merge` will apply the hotfix
branch's commits regardless of `--no-commit` (as documented in the `git
merge` manual).

In the pathological case this will make a `git bisect run` invocation
loop indefinitely between the first bisect step and the fast-forwarded
post-merge HEAD.

Add `--no-ff` to the merge command to avoid this issue.

7b4fb434b4 documentation: remove empty doc files
Remove empty and redundant documentation files from the
Documentation/technical/ directory.

The empty doc files included only TODO messages with no documentation for
years. Instead an approach is being taken to keep all doc beside the code
in the relevant header files.
Having empty doc files is confusing and disappointing to anybody looking
for information, besides having the documentation in header files makes it
easier for developers to find the information they are looking for.

Some of the content which could have gone here already exists elsewhere:
- api-object-access.txt -> sha1-file.c and object.h have some details.
- api-quote.txt -> quote.h has some details.
- api-xdiff-interface.txt -> xdiff-interface.h has some details.

works fine when pushing locally or over SSH, but when pushing over HTTP,
we fail to pass the atomic capability to the remote side.  In fact, we
have not reported this capability to any remote helpers during the life
of the feature.

Now normally, things happen to work nevertheless, since we actually
check for most types of failures, such as non-fast-forward updates, on
the client side, and just abort the entire attempt.  However, if the
server side reports a problem, such as the inability to lock a ref, the
transaction isn't atomic, because we haven't passed the appropriate
capability over and the remote side has no way of knowing that we wanted
atomic behavior.

Fix this by passing the option from the transport code through to remote
helpers, and from the HTTP remote helper down to send-pack.  With this
change, we can detect if the server side rejects the push and report
back appropriately.  Note the difference in the messages: the remote
side reports "atomic transaction failed", while our own checking rejects
pushes with the message "atomic push failed".

Document the atomic option in the remote helper documentation, so other
implementers can implement it if they like.

bf8e65b30b format-patch: teach --cover-from-description option
Before, when format-patch generated a cover letter, only the body would
be populated with a branch's description while the subject would be
populated with placeholder text. However, users may want to have the
subject of their cover letter automatically populated in the same way.

Teach format-patch to accept the `--cover-from-description` option and
corresponding `format.coverFromDescription` config, allowing users to
populate different parts of the cover letter (including the subject
now).

e0479fa073 documentation: add tutorial for object walking
Existing documentation on object walks seems to be primarily intended
as a reference for those already familiar with the procedure. This
tutorial attempts to give an entry-level guide to a couple of bare-bones
object walks so that new Git contributors can learn the concepts
without having to wade through options parsing or special casing.

The target audience is a Git contributor who is just getting started
with the concept of object walking. The goal is to prepare this
contributor to be able to understand and modify existing commands which
perform revision walks more easily, although it will also prepare
contributors to create new commands which perform walks.

The tutorial covers a basic overview of the structs involved during
object walk, setting up a basic commit walk, setting up a basic
all-object walk, and adding some configuration changes to both walk
types. It intentionally does not cover how to create new commands or
search for options from the command line or gitconfigs.

There is an associated patchset at
https://github.com/nasamuffin/git/tree/revwalk that contains a reference
implementation of the code generated by this tutorial.

11a3d3aadd git-rev-list.txt: prune options in synopsis
The synopsis section in git-rev-list.txt has grown to be a huge list
that probably needs its own synopsis. Since the list is huge, users may
be given the false impression that the list is complete, however it is
not. It is missing many of the available options.

Since the list of options in the synopsis is not only annoying but
actively harmful, replace it with `[<options>]` so users know to
explicitly look through the documentation for further information.

While we're at it, update the optional path notation so that it is more
modern.

d54dea77db fetch: let --jobs=<n> parallelize --multiple, too
So far, `--jobs=<n>` only parallelizes submodule fetches/clones, not
`--multiple` fetches, which is unintuitive, given that the option's name
does not say anything about submodules in particular.

Let's change that. With this patch, also fetches from multiple remotes
are parallelized.

For backwards-compatibility (and to prepare for a use case where
submodule and multiple-remote fetches may need different parallelization
limits), the config setting `submodule.fetchJobs` still only controls
the submodule part of `git fetch`, while the newly-introduced setting
`fetch.parallel` controls both (but can be overridden for submodules
with `submodule.fetchJobs`).

87db61a436 trace2: write discard message to sentinel files
Add a new "discard" event type for trace2 event destinations. When the
trace2 file count check creates a sentinel file, it will include the
normal trace2 output in the sentinel, along with this new discard
event.

Writing this message into the sentinel file is useful for tracking how
often the file count check triggers in practice.

83e57b04e6 trace2: discard new traces if target directory has too many files
trace2 can write files into a target directory. With heavy usage, this
directory can fill up with files, causing difficulty for
trace-processing systems.

This patch adds a config option (trace2.maxFiles) to set a maximum
number of files that trace2 will write to a target directory. The
following behavior is enabled when the maxFiles is set to a positive
integer:
  When trace2 would write a file to a target directory, first check
  whether or not the traces should be discarded. Traces should be
  discarded if:
    * there is a sentinel file declaring that there are too many files
    * OR, the number of files exceeds trace2.maxFiles.
  In the latter case, we create a sentinel file named git-trace2-discard
  to speed up future checks.

The assumption is that a separate trace-processing system is dealing
with the generated traces; once it processes and removes the sentinel
file, it should be safe to generate new trace files again.

The default value for trace2.maxFiles is zero, which disables the file
count check.

The config can also be overridden with a new environment variable:
GIT_TRACE2_MAX_FILES.

b8f50e5b60 fast-import: add support for new 'alias' command
fast-export and fast-import have nice --import-marks flags which allow
for incremental migrations.  However, if there is a mark in
fast-export's file of marks without a corresponding mark in the one for
fast-import, then we run the risk that fast-export tries to send new
objects relative to the mark it knows which fast-import does not,
causing fast-import to fail.

This arises in practice when there is a filter of some sort running
between the fast-export and fast-import processes which prunes some
commits programmatically.  Provide such a filter with the ability to
alias pruned commits to their most recent non-pruned ancestor.

f73b2aba05 fast-import: allow tags to be identified by mark labels
Mark identifiers are used in fast-export and fast-import to provide a
label to refer to earlier content.  Blobs are given labels because they
need to be referenced in the commits where they first appear with a
given filename, and commits are given labels because they can be the
parents of other commits.  Tags were never given labels, probably
because they were viewed as unnecessary, but that presents two problems:

   1. It leaves us without a way of referring to previous tags if we
      want to create a tag of a tag (or higher nestings).
   2. It leaves us with no way of recording that a tag has already been
      imported when using --export-marks and --import-marks.

Fix these problems by allowing an optional mark label for tags.

delimiters, Asciidoctor strips off all leading whitespace, resulting in
a misrendered ASCII drawing. Use an explicit literal block to indicate
to Asciidoctor that we want to keep the leading whitespace. Drop the
common indentation for all lines to make this a no-op with AsciiDoc.

user-manual.txt is the only file we process using the "book" doctype.
When we use AsciiDoc, user-manual.conf ensures that the linkgit macro
expands into something like

  <ulink url="git-foo.html">git-foo(1)</ulink>

in user-manual.xml, which we then process into a clickable link, both in
user-manual.html and user-manual.pdf. With Asciidoctor,
user-manual.conf is ignored (this is expected) and our
Asciidoctor-specific implementation of linkgit kicks in:

  <citerefentry>
    <refentrytitle>git-foo</refentrytitle><manvolnum>1</manvolnum>
  </citerefentry>

This eventually renders as "git-foo(1)", which is not bad, but it
doesn't turn into a link.

Teach our Asciidoctor-specific implementation of the linkgit macro that
if the doctype is "book", we should emit <ulink .../> just like we do
with AsciiDoc. While we're doing this, future-proof by supporting a
"prefix". The implementation in user-manual.conf doesn't support this,
and we don't need this for now because user-manual.txt is the only file
we process this way (and it's immediately in Documentation/).

fd5b820d9c user-manual.txt: change header notation
When AsciiDoc processes user-manual.txt, it generates a book containing
chapters containing sections. So for example, we have chapter 6,
"Advanced branch management", which contains four relatively short
sections, 6.1-6.4. Asciidoctor generates a book containing *parts*
containing *chapters* instead. So part 6, "Advanced branch management"
contains four short chapters, 1-4. This looks a bit odd.

To make AsciiDoc (8.6.10) and Asciidoctor (1.5.5) handle these the same,
change from indicating chapters like so:

  [[foobar]]
  Foobar
  ======

to doing it like so:

  [[foobar]]
  == Foobar

Same thing for sections (line of dashes to ===), subsections (line of
tildes to ====) and subsubsections (line of carets to =====). Mark the
appendices with "[appendix]", which both AsciiDoc and Asciidoctor
understand. This means we need to drop the "Appendix X: " from their
titles, or those "Appendix X: " would be included literally in the name
of the appendix.

This commit is a no-op for AsciiDoc: The generated user-manual.xml is
identical before and after this patch. Asciidoctor now creates the same
chapter-section-subsection structure as AsciiDoc.

Changing the book title at the start of the document to similarly use
"=" instead of a line of equal signs makes no difference with any of the
engines, but let's do that change anyway for consistency.

09487f2cba clean: avoid removing untracked files in a nested git repository
Users expect files in a nested git repository to be left alone unless
sufficiently forced (with two -f's).  Unfortunately, in certain
circumstances, git would delete both tracked (and possibly dirty) files
and untracked files within a nested repository.  To explain how this
happens, let's contrast a couple cases.  First, take the following
example setup (which assumes we are already within a git repo):

   git init nested
   cd nested
   >tracked
   git add tracked
   git commit -m init
   >untracked
   cd ..

In this setup, everything works as expected; running 'git clean -fd'
will result in fill_directory() returning the following paths:
   nested/
   nested/tracked
   nested/untracked
and then correct_untracked_entries() would notice this can be compressed
to
   nested/
and then since "nested/" is a directory, we would call
remove_dirs("nested/", ...), which would
check is_nonbare_repository_dir() and then decide to skip it.

However, if someone also creates an ignored file:
   >nested/ignored
then running 'git clean -fd' would result in fill_directory() returning
the same paths:
   nested/
   nested/tracked
   nested/untracked
but correct_untracked_entries() will notice that we had ignored entries
under nested/ and thus simplify this list to
   nested/tracked
   nested/untracked
Since these are not directories, we do not call remove_dirs() which was
the only place that had the is_nonbare_repository_dir() safety check --
resulting in us deleting both the untracked file and the tracked (and
possibly dirty) file.

One possible fix for this issue would be walking the parent directories
of each path and checking if they represent nonbare repositories, but
that would be wasteful.  Even if we added caching of some sort, it's
still a waste because we should have been able to check that "nested/"
represented a nonbare repository before even descending into it in the
first place.  Add a DIR_SKIP_NESTED_GIT flag to dir_struct.flags and use
it to prevent fill_directory() and friends from descending into nested
git repos.

With this change, we also modify two regression tests added in commit
91479b9c72 ("t7300: add tests to document behavior of clean and nested
git", 2015-06-15).  That commit, nor its series, nor the six previous
iterations of that series on the mailing list discussed why those tests
coded the expectation they did.  In fact, it appears their purpose was
simply to test _existing_ behavior to make sure that the performance
changes didn't change the behavior.  However, these two tests directly
contradicted the manpage's claims that two -f's were required to delete
files/directories under a nested git repository.  While one could argue
that the user gave an explicit path which matched files/directories that
were within a nested repository, there's a slippery slope that becomes
very difficult for users to understand once you go down that route (e.g.
what if they specified "git clean -f -d '*.c'"?)  It would also be hard
to explain what the exact behavior was; avoid such problems by making it
really simple.

Also, clean up some grammar errors describing this functionality in the
git-clean manpage.

Finally, there are still a couple bugs with -ffd not cleaning out enough
(e.g.  missing the nested .git) and with -ffdX possibly cleaning out the
wrong files (paying attention to outer .gitignore instead of inner).
This patch does not address these cases at all (and does not change the
behavior relative to those flags), it only fixes the handling when given
a single -f.  See
https://public-inbox.org/git/20190905212043.GC32087@szeder.dev/ for more
discussion of the -ffd[X?] bugs.

e86bbcf987 clean: disambiguate the definition of -d
The -d flag pre-dated git-clean's ability to have paths specified.  As
such, the default for git-clean was to only remove untracked files in
the current directory, and -d existed to allow it to recurse into
subdirectories.

The interaction of paths and the -d option appears to not have been
carefully considered, as evidenced by numerous bugs and a dearth of
tests covering such pairings in the testsuite.  The definition turns out
to be important, so let's look at some of the various ways one could
interpret the -d option:

  A) Without -d, only look in subdirectories which contain tracked
     files under them; with -d, also look in subdirectories which
     are untracked for files to clean.

  B) Without specified paths from the user for us to delete, we need to
     have some kind of default, so...without -d, only look in
     subdirectories which contain tracked files under them; with -d,
     also look in subdirectories which are untracked for files to clean.

The important distinction here is that choice B says that the presence
or absence of '-d' is irrelevant if paths are specified.  The logic
behind option B is that if a user explicitly asked us to clean a
specified pathspec, then we should clean anything that matches that
pathspec.  Some examples may clarify.  Should

   git clean -f untracked_dir/file

remove untracked_dir/file or not?  It seems crazy not to, but a strict
reading of option A says it shouldn't be removed.  How about

   git clean -f untracked_dir/file1 tracked_dir/file2

or

   git clean -f untracked_dir_1/file1 untracked_dir_2/file2

?  Should it remove either or both of these files?  Should it require
multiple runs to remove both the files listed?  (If this sounds like a
crazy question to even ask, see the commit message of "t7300: Add some
testcases showing failure to clean specified pathspecs" added earlier in
this patch series.)  What if -ffd were used instead of -f -- should that
allow these to be removed?  Should it take multiple invocations with
-ffd?  What if a glob (such as '*tracked*') were used instead of
spelling out the directory names?  What if the filenames involved globs,
such as

   git clean -f '*.o'

or

   git clean -f '*/*.o'

?

The current documentation actually suggests a definition that is
slightly different than choice A, and the implementation prior to this
series provided something radically different than either choices A or
B. (The implementation, though, was clearly just buggy).  There may be
other choices as well.  However, for almost any given choice of
definition for -d that I can think of, some of the examples above will
appear buggy to the user.  The only case that doesn't have negative
surprises is choice B: treat a user-specified path as a request to clean
all untracked files which match that path specification, including
recursing into any untracked directories.

Change the documentation and basic implementation to use this
definition.

There were two regression tests that indirectly depended on the current
implementation, but neither was about subdirectory handling.  These two
tests were introduced in commit 5b7570cfb4 ("git-clean: add tests for
relative path", 2008-03-07) which was solely created to add coverage for
the changes in commit fb328947c8e ("git-clean: correct printing relative
path", 2008-03-07).  Both tests specified a directory that happened to
have an untracked subdirectory, but both were only checking that the
resulting printout of a file that was removed was shown with a relative
path.  Update these tests appropriately.

A poster on Stackoverflow was confused that the documentation of git-log

none to be found. Rewrite the corresponding paragraph to talk about
"patch text" to avoid the confusion.

Shorten the language to say "X does Y" in place of "X does not Z, but Y".

Cross-reference the referred-to commands like the rest of the file does.

83b0b8953e doc-diff: replace --cut-header-footer with --cut-footer
After the previous commit, AsciiDoc and Asciidoctor render the manpage
headers identically, so we no longer need the "cut the header" part of
our `--cut-header-footer` option. We do still need the "cut the footer"
part, though. The previous commits improved the rendering of the footer
in Asciidoctor by quite a bit, but the two programs still disagree on
how to format the date in the footer: 01/01/1970 vs 1970-01-01.

We could keep using `--cut-header-footer`, but it would be nice if we
had a slightly smaller hammer `--cut-footer` that would be less likely
to hide regressions. Rather than simply adding such an option, let's
also drop `--cut-header-footer`, i.e., rework it to lose the "header"
part of its name and functionality.

`--cut-header-footer` is just a developer tool and it probably has no
more than a handful of users, so we can afford to be aggressive.

7a30134358 asciidoctor-extensions: provide <refmiscinfo/>
As can be seen from the previous commit, there are three attributes that
we provide to AsciiDoc through asciidoc.conf. Asciidoctor ignores that
file. After that patch, newer versions of Asciidoctor pick up the
`manmanual` and `mansource` attributes as we invoke `asciidoctor`, but
they don't pick up `manversion`. ([1] says: "Not used by Asciidoctor.")
Older versions (<1.5.7) don't handle these attributes at all. As a
result, we are missing one or three `<refmiscinfo/>` tags in each
xml-file produced when we build with Asciidoctor.

Because of this, xmlto doesn't include the Git version number in the
rendered manpages. And in particular, with versions <1.5.7, the manpage
footers instead contain the fairly ugly "[FIXME: source]".

That Asciidoctor ignores asciidoc.conf is nothing new. This is why we
implement the `linkgit:` macro in asciidoc.conf *and* in
asciidoctor-extensions.rb. Follow suit and provide these tags in
asciidoctor-extensions.rb, using a "postprocessor" extension where we
just search and replace in the XML, treated as text.

We may consider a few alternatives:

  * Inject these lines into the xml-files from the *Makefile*, e.g.,
    using `sed`. That would reduce repetition, but it feels wrong to
    impose another step and another risk on the AsciiDoc-processing only
    to benefit the Asciidoctor-one.

  * I tried providing a "docinfo processor" to inject these tags, but
    could not figure out how to "merge" the two <refmeta/> sections that
    resulted. To avoid xmlto barfing on the result, I needed to use
    `xmlto --skip-validation ...`, which seems unfortunate.

Let's instead inject the missing tags using a postprocessor. We'll make
it fairly obvious that we aim to inject the exact same three lines of
`<refmiscinfo/>` that asciidoc.conf provides. We inject them in
*post*-processing so we need to do the variable expansion ourselves. We
do introduce the bug that asciidoc.conf already has in that we won't do
any escaping, e.g., of funky versions like "some v <2.25, >2.20".

The postprocessor we add here works on the XML as raw text and doesn't
really use the full potential of XML to do a more structured injection.
This is actually precisely what the Asciidoctor User Manual does in its
postprocessor example [2]. I looked into two other approaches:

  1. The nokogiri library is apparently the "modern" way of doing XML
     in ruby. I got it working fairly easily:
        require 'nokogiri'
        doc = Nokogiri::XML(output)
        doc.search("refmeta").each { |n| n.add_child(new_tags) }
        output = doc.to_xml
     However, this adds another dependency (e.g., the "ruby-nokogiri"
     package on Ubuntu). Using Asciidoctor is not our default, but it
     will probably need to become so soon. Let's avoid adding a
     dependency just so that we can say "search...add_child" rather than
     "sub(regex...)".

  2. The older REXML is apparently always(?) bundled with ruby, but I
     couldn't even parse the original document:
        require 'rexml/document'
        doc = REXML::Document.new(output)
        ...
     The error was "no implicit conversion of nil into String" and I
     stopped there.

I don't think it's unlikely that doing a plain old search-and-replace
will work just as fine or better compared to parsing XML and worrying
about libraries and library versions.

226daba280 Doc/Makefile: give mansource/-version/-manual attributes
Rather than hardcoding "Git Manual" and "Git" as the manual and source
in asciidoc.conf, provide them as attributes `manmanual` and
`mansource`. Rename the `git_version` attribute to `manversion`.

These new attribute names are not arbitrary, see, e.g., [1].

For AsciiDoc (8.6.10) and Asciidoctor <1.5.7, this is a no-op. Starting
with Asciidoctor 1.5.7, `manmanual` and `mansource` actually end up in
the xml-files and eventually in the rendered manpages. In particular,
the manpage headers now render just as with AsciiDoc.

No versions of Asciidoctor pick up the `manversion` [2], and older
versions don't pick up any of these attributes. -- We'll fix that with a
bit of a hack in the next commit.

40e747e89d git-submodule.txt: fix AsciiDoc formatting error
In b57e8119e6 (submodule: teach set-branch subcommand, 2019-02-08), the
`set-branch` subcommand was added for submodules. When the documentation
was written, the syntax for a "index term" in AsciiDoc was
accidentally used. This caused the documentation to be rendered as

	set-branch -d|--default)|(-b|--branch <branch> [--] <path>

instead of

	set-branch ((-d|--default)|(-b|--branch <branch>)) [--] <path>

In addition to this, the original documentation was possibly confusing
as it made it seem as if the `-b` option didn't accept a `<branch>`
argument.

Break `--default` and `--branch` into their own separate invocations to
make it obvious that these options are mutually exclusive. Also, this
removes the surrounding parentheses so that the "index term" syntax is
not triggered.

f6461b82b9 Documentation: fix build with Asciidoctor 2
Our documentation toolchain has traditionally been built around DocBook
4.5.  This version of DocBook is the last DTD-based version of DocBook.
In 2009, DocBook 5 was introduced using namespaces and its syntax is
expressed in RELAX NG, which is more expressive and allows a wider
variety of syntax forms.

Asciidoctor, one of the alternatives for building our documentation,
moved support for DocBook 4.5 out of core in its recent 2.0 release and
now only supports DocBook 5 in the main release.  The DocBoook 4.5
converter is still available as a separate component, but this is not
available in most distro packages.  This would not be a problem but for
the fact that we use xmlto, which is still stuck in the DocBook 4.5 era.

xmlto performs DTD validation as part of the build process.  This is not
problematic for DocBook 4.5, which has a valid DTD, but it clearly
cannot work for DocBook 5, since no DTD can adequately express its full
syntax.  In addition, even if xmlto did support RELAX NG validation,
that wouldn't be sufficient because it uses the libxml2-based xmllint to
do so, which has known problems with validating interleaves in RELAX NG.

Fortunately, there's an easy way forward: ask Asciidoctor to use its
DocBook 5 backend and tell xmlto to skip validation.  Asciidoctor has
supported DocBook 5 since v0.1.4 in 2013 and xmlto has supported
skipping validation for probably longer than that.

We also need to teach xmlto how to use the namespaced DocBook XSLT
stylesheets instead of the non-namespaced ones it usually uses.
Normally these stylesheets are interchangeable, but the non-namespaced
ones have a bug that causes them not to strip whitespace automatically
from certain elements when namespaces are in use.  This results in
additional whitespace at the beginning of list elements, which is
jarring and unsightly.

We can do this by passing a custom stylesheet with the -x option that
simply imports the namespaced stylesheets via a URL.  Any system with
support for XML catalogs will automatically look this URL up and
reference a local copy instead without us having to know where this
local copy is located.  We know that anyone using xmlto will already
have catalogs set up properly since the DocBook 4.5 DTD used during
validation is also looked up via catalogs.  All major Linux
distributions distribute the necessary stylesheets and have built-in
catalog support, and Homebrew does as well, albeit with a requirement to
set an environment variable to enable catalog support.

On the off chance that someone lacks support for catalogs, it is
possible for xmlto (via xmllint) to download the stylesheets from the
URLs in question, although this will likely perform poorly enough to
attract attention.  People still have the option of using the prebuilt
documentation that we ship, so happily this should not be an impediment.

Finally, we need to filter out some messages from other stylesheets that
occur when invoking dblatex in the CI job.  This tool strips namespaces
much like the unnamespaced DocBook stylesheets and prints similar
messages.  If we permit these messages to be printed to standard error,
our documentation CI job will fail because we check standard error for
unexpected output.  Due to dblatex's reliance on Python 2, we may need
to revisit its use in the future, in which case this problem may go
away, but this can be delayed until a future patch.

The final message we filter is due to libxslt on modern Debian and
Ubuntu.  The patch which they use to implement reproducible ID
generation also prints messages about the ID generation.  While this
doesn't affect our current CI images since they use Ubuntu 16.04 which
lacks this patch, if we upgrade to Ubuntu 18.04 or a modern Debian,
these messages will appear and, like the above messages, cause a CI
failure.

4414e837fc gitweb.conf.txt: switch pluses to backticks to help Asciidoctor
This paragraph uses a lot of +pluses+ to render text as monospace. That
works fine with AsciiDoc (8.6.10), and almost fine with Asciidoctor
(1.5.5), which renders the third of these literally ("+$projname+"). The
reason seems to be that Asciidoctor trips on the lone plus a bit
earlier, even though it is escaped.

Switch +$projname+ to `$projname`, and change the next, similar instance
too (+$projname/+), because otherwise, we'd trip on /that one/ instead.
If we would stop there, we would now start falling over on the escaped
plus ('\+') mentioned earlier, rendering /it/ literally. So change that
too...

In other words, unescape the lone '+' and change all the pluses that
follow it to backticks.

AsciiDoc renders this paragraph identically before and after this
commit, and Asciidoctor now renders this the same as AsciiDoc.

I did try to switch the whole paragraph to using backticks rather than
pluses. That worked great with Asciidoctor, but confused AsciiDoc...
Let's go with this rather surgical change instead.

b7e1ba5649 git-merge-index.txt: wrap shell listing in "----"
The example output of `git merge-index` has been enriched by a second
"column" of helpful comments. When Asciidoctor renders this, the cells
in that second column aren't aligned.

Fix this by marking the example shell session as a code listing by
wrapping it in "----". Also drop some of the horizontal space between
the two columns so that we fit into 80 columns. This changes the
rendering with both AsciiDoc and Asciidoctor. They now render this
identically, nicely aligned, and within 80 columns.

922a2c93f5 git-merge-base.txt: render indentations correctly under Asciidoctor
There are several graphs in this document. For most of them, we use a
single leading tab to indent the whole graph, and then we use spaces
(possibly eight or more) to align things within the graph.

In the larger graph, we use a different strategy: We use 1-N tabs and
just a small number of spaces (<8). This is how we usually prefer to do
our indenting, but Asciidoctor ends up rendering this differently from
AsciiDoc. Same thing for the if-then-fi examples where the conditional
code is indented by two tabs, which renders differently under AsciiDoc
and Asciidoctor.

Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables. Change not
just the ones that render differently, but all of them for consistency.

Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first tab of
indentation on each line. With AsciiDoc, this results in identical
rendering before and after this commit, both for git-merge-base.1 and
git-merge-base.html.

A less intrusive change would be to replace tabs 2-N on each line with
eight spaces. But let's follow the example set by 379805051d, so that we
can use our preferred way of indenting.

2017956a19 Documentation: wrap blocks with "--"
The documentation for each of these options contains a list. After the
list, AsciiDoc interprets the continuation as a continuation of the
*list*, not as a continution of the larger block. As a result, we get
too much indentation. Wrap the entire blocks in "--" to fix this. With
Asciidoctor, this commit is a no-op, and the two programs now render
these identically.

These two files share the same problem and indeed, they both document
`--untracked-files` in quite similar ways. I haven't checked to what
extent that is intentional or warranted, and to what extent they have
simply drifted apart. I consider such an investigation and possible
cleanup as out of scope for this commit and this patch series.

65edd96aec treewide: rename 'exclude' methods to 'pattern'
The first consumer of pattern-matching filenames was the
.gitignore feature. In that context, storing a list of patterns
as a 'struct exclude_list'  makes sense. However, the
sparse-checkout feature then adopted these structures and methods,
but with the opposite meaning: these patterns match the files
that should be included!

It would be clearer to rename this entire library as a "pattern
matching" library, and the callers apply exclusion/inclusion
logic accordingly based on their needs.

This commit renames several methods defined in dir.h to make
more sense with the renamed 'struct exclude_list' to 'struct
pattern_list' and 'struct exclude' to 'struct path_pattern':

 * last_exclude_matching() -> last_matching_pattern()
 * parse_exclude() -> parse_path_pattern()

In addition, the word 'exclude' was replaced with 'pattern'
in the methods below:

 * add_exclude_list()
 * add_excludes_from_file_to_list()
 * add_excludes_from_file()
 * add_excludes_from_blob_to_list()
 * add_exclude()
 * clear_exclude_list()

A few methods with the word "exclude" remain. These will
be handled seperately. In particular, the method
"is_excluded()" is concretely about the .gitignore file
relative to a specific directory. This is the important
boundary between library and consumer: is_excluded() cares
about .gitignore, but is_excluded() calls
last_matching_pattern() to make that decision.

9df53c5de6 Recommend git-filter-repo instead of git-filter-branch
filter-branch suffers from a deluge of disguised dangers that disfigure
history rewrites (i.e. deviate from the deliberate changes).  Many of
these problems are unobtrusive and can easily go undiscovered until the
new repository is in use.  This can result in problems ranging from an
even messier history than what led folks to filter-branch in the first
place, to data loss or corruption.  These issues cannot be backward
compatibly fixed, so add a warning to both filter-branch and its manpage
recommending that another tool (such as filter-repo) be used instead.

Also, update other manpages that referenced filter-branch.  Several of
these needed updates even if we could continue recommending
filter-branch, either due to implying that something was unique to
filter-branch when it applied more generally to all history rewriting
tools (e.g. BFG, reposurgeon, fast-import, filter-repo), or because
something about filter-branch was used as an example despite other more
commonly known examples now existing.  Reword these sections to fix
these issues and to avoid recommending filter-branch.

Finally, remove the section explaining BFG Repo Cleaner as an
alternative to filter-branch.  I feel somewhat bad about this,
especially since I feel like I learned so much from BFG that I put to
good use in filter-repo (which is much more than I can say for
filter-branch), but keeping that section presented a few problems:
  * In order to recommend that people quit using filter-branch, we need
    to provide them a recomendation for something else to use that
    can handle all the same types of rewrites.  To my knowledge,
    filter-repo is the only such tool.  So it needs to be mentioned.
  * I don't want to give conflicting recommendations to users
  * If we recommend two tools, we shouldn't expect users to learn both
    and pick which one to use; we should explain which problems one
    can solve that the other can't or when one is much faster than
    the other.
  * BFG and filter-repo have similar performance
  * All filtering types that BFG can do, filter-repo can also do.  In
    fact, filter-repo comes with a reimplementation of BFG named
    bfg-ish which provides the same user-interface as BFG but with
    several bugfixes and new features that are hard to implement in
    BFG due to its technical underpinnings.
While I could still mention both tools, it seems like I would need to
provide some kind of comparison and I would ultimately just say that
filter-repo can do everything BFG can, so ultimately it seems that it
is just better to remove that section altogether.

50f26bd035 fetch: add fetch.writeCommitGraph config setting
The commit-graph feature is now on by default, and is being
written during 'git gc' by default. Typically, Git only writes
a commit-graph when a 'git gc --auto' command passes the gc.auto
setting to actualy do work. This means that a commit-graph will
typically fall behind the commits that are being used every day.

To stay updated with the latest commits, add a step to 'git
fetch' to write a commit-graph after fetching new objects. The
fetch.writeCommitGraph config setting enables writing a split
commit-graph, so on average the cost of writing this file is
very small. Occasionally, the commit-graph chain will collapse
to a single level, and this could be slow for very large repos.

For additional use, adjust the default to be true when
feature.experimental is enabled.
