config.txt is going to be broken down in smaller pieces and put under
Documentation/config directory. Update build rules to take these files
into account.
A dummy file is added to make sure wildcard expansion is predictable
(depending on shell setting it could expand to nothing or becomes a
path if config directory is empty). The file will be deleted once the
move is over.

"git cmd --help" when "cmd" is aliased used to only say "cmd is
aliased to ...". Now it shows that to the standard error stream
and runs "git $cmd --help" where $cmd is the first word of the
alias expansion.
This could be misleading for those who alias a command with options
(e.g. with "[alias] cpn = cherry-pick -n", "git cpn --help" would
show the manual of "cherry-pick", and the reader would not be told
to pay close attention to the part that describes the "--no-commit"
option until closing the pager that showed the contents of the
manual, if the pager is configured to restore the original screen,
or would not be told at all, if the pager simply makes the message
on the standard error scroll away.
* rv/alias-help:

As of cURL v7.60.0, the Secure Channel backend can use the certificate
bundle provided via `http.sslCAInfo`, but that would override the
Windows Certificate Store. Since this is not desirable by default, let's
tell Git to not ask cURL to use that bundle by default when the `schannel`
backend was configured via `http.sslBackend`, unless
`http.schannelUseSSLCAInfo` overrides this behavior.

This adds support for a new http.schannelCheckRevoke config value.
This config value is only used if http.sslBackend is set to "schannel",
which forces cURL to use the Windows Certificate Store when validating
server certificates associated with a remote server.
This config value should only be set to "false" if you are in an
environment where revocation checks are blocked by the network, with
no alternative options.
This is only supported in cURL 7.44 or later.
Note: originally, we wanted to call the config setting
`http.schannel.checkRevoke`. This, however, does not work: the `http.*`
config settings can be limited to specific URLs via `http.<url>.*`
(and this feature would mistake `schannel` for a URL).

refresh_index() is done after a reset command as an optimization. Because
it can be an expensive call, warn the user if it takes more than 2 seconds
and tell them how to avoid it using the --quiet command line option or

Add a reset.quiet config setting that sets the default value of the --quiet
flag when running the reset command. This enables users to change the
default behavior to take advantage of the performance advantages of
avoiding the scan for unstaged changes after reset. Defaults to false.

When pushing into a repository that borrows its objects from an
alternate object store, "git receive-pack" that responds to the
push request on the other side lists the tips of refs in the
alternate to reduce the amount of objects transferred. This
sometimes is detrimental when the number of refs in the alternate
is absurdly large, in which case the bandwidth saved in potentially
fewer objects transferred is wasted in excessively large ref
advertisement. The alternate refs that are advertised are now
configurable with a pair of configuration variables.

"git help -a" and "git help -av" give different pieces of
information, and generally the "verbose" version is more friendly
to the new users. "git help -a" by default now uses the more
verbose output (with "--no-verbose", you can go back to the
original). Also "git help -av" now lists aliases and external
commands, which it did not used to.

corrected to use exit(1). Also the error reporting behaviour when

The previous git-p4 unshelve support would check for changes
in Perforce to the files being unshelved since the original
shelve, and would complain if any were found.
This was to ensure that the user wouldn't end up with both the
shelved change delta, and some deltas from other changes in their
git commit.
e.g. given fileA:
the
quick
brown
fox
change1: s/the/The/ <- p4 shelve this change
change2: s/fox/Fox/ <- p4 submit this change
git p4 unshelve 1 <- FAIL
This change teaches the P4Unshelve class to always create a parent
commit which matches the P4 tree (for the files being unshelved) at
the point prior to the P4 shelve being created (which is reported
in the p4 description for a shelved changelist).
That then means git-p4 can always create a git commit matching the
P4 shelve that was originally created, without any extra deltas.
The user might still need to use the --origin option though - there
is no way for git-p4 to work out the versions of all of the other
*unchanged* files in the shelve, since this information is not recorded
by Perforce.
Additionally this fixes handling of shelved 'move' operations.

The branch detection code looks for branches under refs/remotes/p4/...
and can end up getting confused if there are unshelved changes in
there as well. This happens in the function p4BranchesInGit().
Instead, put the unshelved changes into refs/remotes/p4-unshelved/<N>.

As of version 7.56.0, curl supports being compiled with multiple SSL
backends.
This patch adds the Git side of that feature: by setting http.sslBackend
to "openssl" or "schannel", Git for Windows can now choose the SSL
backend at runtime.
This comes in handy on Windows because Secure Channel ("schannel") is
the native solution, accessing the Windows Credential Store, thereby
allowing for enterprise-wide management of certificates. For historical
reasons, Git for Windows needs to support OpenSSL still, as it has
previously been the only supported SSL backend in Git for Windows for
almost a decade.
The patch has been carried in Git for Windows for over a year, and is
considered mature.

Explicitly mention in the intro that we may be writing supplemental
data structures such as the commit-graph during "gc", i.e. to call out
the "optimize" part of what this command does, it doesn't just
"collect garbage" as the "gc" name might imply.
Past changes have updated the intro to reflect new commands, such as
mentioning "worktree" in b586a96a39 ("gc.txt: more details about what
gc does", 2018-03-15). So let's elaborate on what was added in
d5d5d7b641 ("gc: automatically write commit-graph files", 2018-06-27).
See also

This patch enables addressing the CPU cost of loading the index by adding
additional data to the index that will allow us to efficiently multi-
thread the loading and conversion of cache entries.
It accomplishes this by adding an (optional) index extension that is a
table of offsets to blocks of cache entries in the index file. To make
this work for V4 indexes, when writing the cache entries, it periodically
"resets" the prefix-compression by encoding the current entry as if the
path name for the previous entry is completely different and saves the
offset of that entry in the IEOT. Basically, with V4 indexes, it
generates offsets into blocks of prefix-compressed entries.

Add support for a new index.threads config setting which will be used to
control the threading code in do_read_index(). A value of 0 will tell the
index code to automatically determine the correct number of threads to use.
A value of 1 will make the code single threaded. A value greater than 1
will set the maximum number of threads to use.
For testing purposes, this setting can be overwritten by setting the
GIT_TEST_INDEX_THREADS=<n> environment variable to a value greater than 0.

The End of Index Entry (EOIE) is used to locate the end of the variable
length index entries and the beginning of the extensions. Code can take
advantage of this to quickly locate the index extensions without having
to parse through all of the index entries.
The EOIE extension is always written out to the index file including to
the shared index when using the split index feature. Because it is always
written out, the SHA checksums in t/t1700-split-index.sh were updated
to reflect its inclusion.
It is written as an optional extension to ensure compatibility with other
git implementations that do not yet support it. It is always written out
to ensure it is available as often as possible to speed up index operations.
Because it must be able to be loaded before the variable length cache
entries and other index extensions, this extension must be written last.
The signature for this extension is { 'E', 'O', 'I', 'E' }.
The extension consists of:
- 32-bit offset to the end of the index entries
- 160-bit SHA-1 over the extension types and their sizes (but not
their contents). E.g. if we have "TREE" extension that is N-bytes
long, "REUC" extension that is M-bytes long, followed by "EOIE",
then the hash would be:
SHA-1("TREE" + <binary representation of N> +
"REUC" + <binary representation of M>)
