Jacob Keller 4f655e22b7 notes: teach git-notes about notes.<name>.mergeStrategy option
Teach notes about a new "notes.<name>.mergeStrategy" option for
configuring the notes merge strategy when merging into
refs/notes/<name>. This option allows for the selection of merge
strategy for particular notes refs, rather than all notes ref merges, as
user may not want cat_sort_uniq for all refs, but only some. Note that
the <name> is the local reference we are merging into, not the remote
ref we merged from. The assumption is that users will mostly want to
configure separate local ref merge strategies rather than strategies
depending on which remote ref they merge from.

notes.<name>.mergeStrategy overrides the general behavior as it is more
specific.

Jeff King 2bc31d1631 refs: support negative transfer.hideRefs
If you hide a hierarchy of refs using the transfer.hideRefs
config, there is no way to later override that config to
"unhide" it. This patch implements a "negative" hide which
causes matches to immediately be marked as unhidden, even if
another match would hide it. We take care to apply the
matches in reverse-order from how they are fed to us by the
config machinery, as that lets our usual "last one wins"
config precedence work (and entries in .git/config, for
example, will override /etc/gitconfig).

So you can now do:

  $ git config --system transfer.hideRefs refs/secret
  $ git config transfer.hideRefs '!refs/secret/not-so-secret'

to hide refs/secret in all repos, except for one public bit
in one specific repo. Or you can even do:

  $ git clone \
      -u "git -c transfer.hiderefs="!refs/foo" upload-pack" \
      remote:repo.git

to clone remote:repo.git, overriding any hiding it has
configured.

There are two alternatives that were considered and
rejected:

  1. A generic config mechanism for removing an item from a
     list. E.g.: (e.g., "[transfer] hideRefs -= refs/foo").

     This is nice because it could apply to other
     multi-valued config, as well. But it is not nearly as
     flexible. There is no way to say:

       [transfer]
       hideRefs = refs/secret
       hideRefs = refs/secret/not-so-secret

     Having explicit negative specifications means we can
     override previous entries, even if they are not the
     same literal string.

  2. Adding another variable to override some parts of
     hideRefs (e.g., "exposeRefs").

     This solves the problem from alternative (1), but it
     cannot easily obey the normal config precedence,
     because it would use two separate lists. For example:

       [transfer]
       hideRefs = refs/secret
       exposeRefs = refs/secret/not-so-secret
       hideRefs = refs/secret/not-so-secret/no-really-its-secret

     With two lists, we have to apply the "expose" rules
     first, and only then apply the "hide" rules. But that
     does not match what the above config intends.

     Of course we could internally parse that to a single
     list, respecting the ordering, which saves us having to
     invent the new "!" syntax. But using a single name
     communicates to the user that the ordering _is_
     important. And "!" is well-known for negation, and
     should not appear at the beginning of a ref (it is
     actually valid in a ref-name, but all entries here
     should be fully-qualified, starting with "refs/").

Jeff King cc118a65b4 docs/config.txt: reorder hideRefs config
The descriptions for receive.hideRefs and
uploadpack.hideRefs are largely the same, and then
transfer.hideRefs refers to both of them. Instead, let's
make transfer.hideRefs the "master" source, and refer to it
from the other sites (with appropriate program-specific
annotations).

This avoids duplication, and will make it easier to document
changes to the config option without having to copy and
paste the description in two places.

While we're at it, this fixes some bogus subject/verb
agreement in the original description.

Galan Rémi 3707995960 git rebase -i: warn about removed commits
Check if commits were removed (i.e. a line was deleted) and print
warnings or stop git rebase depending on the value of the
configuration variable rebase.missingCommitsCheck.

This patch gives the user the possibility to avoid silent loss of
information (losing a commit through deleting the line in this case)
if he wants.

Add the configuration variable rebase.missingCommitsCheck.
    - When unset or set to "ignore", no checking is done.
    - When set to "warn", the commits are checked, warnings are
      displayed but git rebase still proceeds.
    - When set to "error", the commits are checked, warnings are
      displayed and the rebase is stopped.
      (The user can then use 'git rebase --edit-todo' and
      'git rebase --continue', or 'git rebase --abort')

rebase.missingCommitsCheck defaults to "ignore".

Identical to support in `git receive-pack for the config option
`receive.fsck.skiplist`, we now support ignoring given objects in

This is extremely handy in case of legacy repositories where it would
cause more pain to change incorrect objects than to live with them

Johannes Schindelin cd94c6f91e fsck: git receive-pack: support excluding objects from fsck'ing
The optional new config option `receive.fsck.skipList` specifies the path
to a file listing the names, i.e. SHA-1s, one per line, of objects that
are to be ignored by `git receive-pack` when `receive.fsckObjects = true`.

This is extremely handy in case of legacy repositories where it would
cause more pain to change incorrect objects than to live with them
(e.g. a duplicate 'author' line in an early commit object).

The intended use case is for server administrators to inspect objects
that are reported by `git push` as being too problematic to enter the
repository, and to add the objects' SHA-1 to a (preferably sorted) file
when the objects are legitimate, i.e. when it is determined that those
problematic objects should be allowed to enter the server.

Johannes Schindelin 2becf00ff7 fsck: support demoting errors to warnings
We already have support in `git receive-pack` to deal with some legacy
repositories which have non-fatal issues.

Let's make `git fsck` itself useful with such repositories, too, by
allowing users to ignore known issues, or at least demote those issues
to mere warnings.

Example: `git -c fsck.missingEmail=ignore fsck` would hide
problems with missing emails in author, committer and tagger lines.

In the same spirit that `git receive-pack`'s usage of the fsck machinery
differs from `git fsck`'s – some of the non-fatal warnings in `git fsck`
are fatal with `git receive-pack` when receive.fsckObjects = true, for
example – we strictly separate the fsck.<msg-id> from the
receive.fsck.<msg-id> settings.

Fredrik Medley 68ee628932 upload-pack: optionally allow fetching reachable sha1
With uploadpack.allowReachableSHA1InWant configuration option set on the
server side, "git fetch" can make a request with a "want" line that names
an object that has not been advertised (likely to have been obtained out
of band or from a submodule pointer). Only objects reachable from the
branch tips, i.e. the union of advertised branches and branches hidden by
transfer.hideRefs, will be processed. Note that there is an associated
cost of having to walk back the history to check the reachability.

This feature can be used when obtaining the content of a certain commit,
for which the sha1 is known, without the need of cloning the whole
repository, especially if a shallow fetch is used. Useful cases are e.g.
repositories containing large files in the history, fetching only the
needed data for a submodule checkout, when sharing a sha1 without telling
which exact branch it belongs to and in Gerrit, if you think in terms of
commits instead of change numbers. (The Gerrit case has already been
solved through allowTipSHA1InWant as every Gerrit change has a ref.)

Paul Tan eb8dc05c3d pull: make pull.ff=true override merge.ff
Since b814da8 (pull: add pull.ff configuration, 2014-01-15), running
git-pull with the configuration pull.ff=false or pull.ff=only is
equivalent to passing --no-ff and --ff-only to git-merge. However, if
pull.ff=true, no switch is passed to git-merge. This leads to the
confusing behavior where pull.ff=false or pull.ff=only is able to
override merge.ff, while pull.ff=true is unable to.

Fix this by adding the --ff switch if pull.ff=true, and add a test to
catch future regressions.

Furthermore, clarify in the documentation that pull.ff overrides
merge.ff.

Michael Haggerty f4ab4f3ab1 lock_packed_refs(): allow retries when acquiring the packed-refs lock
Currently, there is only one attempt to acquire any lockfile, and if
the lock is held by another process, the locking attempt fails
immediately.

This is not such a limitation for loose reference files. First, they
don't take long to rewrite. Second, most reference updates have a
known "old" value, so if another process is updating a reference at
the same moment that we are trying to lock it, then probably the
expected "old" value will not longer be valid, and the update will
fail anyway.

But these arguments do not hold for packed-refs:

* The packed-refs file can be large and take significant time to
  rewrite.

* Many references are stored in a single packed-refs file, so it could
  be that the other process was changing a different reference than
  the one that we are interested in.

Therefore, it is much more likely for there to be spurious lock
conflicts in connection to the packed-refs file, resulting in
unnecessary command failures.

So, if the first attempt to lock the packed-refs file fails, continue
retrying for a configurable length of time before giving up. The
default timeout is 1 second.

Jeff King 1c262bb7b2 doc: convert \--option to --option
Older versions of AsciiDoc would convert the "--" in
"--option" into an emdash. According to 565e135
(Documentation: quote double-dash for AsciiDoc, 2011-06-29),
this is fixed in AsciiDoc 8.3.0. According to bf17126, we
don't support anything older than 8.4.1 anyway, so we no
longer need to worry about quoting.

Even though this does not change the output at all, there
are a few good reasons to drop the quoting:

  1. It makes the source prettier to read.

  2. We don't quote consistently, which may be confusing when
     reading the source.

  3. Asciidoctor does not like the quoting, and renders a
     literal backslash.
