It *is* a confusing thing to look at a diff of diffs. All too easy is it
to mix up whether the -/+ markers refer to the "inner" or the "outer"
diff, i.e. whether a `+` indicates that a line was added by either the
old or the new diff (or both), or whether the new diff does something
different than the old diff.
To make things easier to process for normal developers, we introduced
the dual color mode which colors the lines according to the commit diff,
i.e. lines that are added by a commit (whether old, new, or both) are
colored in green. In non-dual color mode, the lines would be colored
according to the outer diff: if the old commit added a line, it would be
colored red (because that line addition is only present in the first
commit range that was specified on the command-line, i.e. the "old"
commit, but not in the second commit range, i.e. the "new" commit).
However, this dual color mode is still not making things clear enough,
as we are looking at two levels of diffs, and we still only pick a color
according to *one* of them (the outer diff marker is colored
differently, of course, but in particular with deep indentation, it is
easy to lose track of that outer diff marker's background color).
Therefore, let's add another dimension to the mix. Still use
green/red/normal according to the commit diffs, but now also dim the
lines that were only in the old commit, and use bold face for the lines
that are only in the new commit.
That way, it is much easier not to lose track of, say, when we are
looking at a line that was added in the previous iteration of a patch
series but the new iteration adds a slightly different version: the
obsolete change will be dimmed, the current version of the patch will be
bold.
At least this developer has a much easier time reading the range-diffs
that way.

The colorization is controlled with the config setting "color.remote".
Supported keywords are "error", "warning", "hint" and "success". They
are highlighted if they appear at the start of the line, which is
common in error messages, eg.
ERROR: commit is missing Change-Id
The Git push process itself prints lots of non-actionable messages
(eg. bandwidth statistics, object counters for different phases of the
process). This obscures actionable error messages that servers may
send back. Highlighting keywords in the sideband draws more attention
to those messages.
The background for this change is that Gerrit does server-side
processing to create or update code reviews, and actionable error
messages (eg. missing Change-Id) must be communicated back to the user
during the push. User research has shown that new users have trouble
seeing these messages.
The highlighting is done on the client rather than server side, so
servers don't have to grow capabilities to understand terminal escape
codes and terminal state. It also consistent with the current state
where Git is control of the local display (eg. prefixing messages with
"remote: ").
The highlighting can be configured using color.remote.<KEYWORD>
configuration settings. Since the keys are matched case insensitively,
we match the keywords case insensitively too.
Finally, this solution is backwards compatible: many servers already
prefix their messages with "error", and they will benefit from this
change without requiring a server update. By contrast, a server-side
solution would likely require plumbing the TERM variable through the
git protocol, so it would require changes to both server and client.

Change the handling of fetch.negotiationAlgorithm=<str> to error out
on unknown strings, i.e. everything except "default" or "skipping".
This changes the behavior added in 42cc7485a2 ("negotiator/skipping:
skip commits during fetch", 2018-07-16) which would ignore all unknown
values and silently fall back to the "default" value.
For a feature like this it's much better to produce an error than
proceed. We don't want users to debug some amazingly slow fetch that
should benefit from "skipping", only to find that they'd forgotten to
deploy the new git version on that particular machine.

Implement support for fetch.fsck.* corresponding with the existing
receive.fsck.*. This allows for pedantically cloning repositories with
specific issues without turning off fetch.fsckObjects.
One such repository is https://github.com/robbyrussell/oh-my-zsh.git
which before this change will emit this error when cloned with
fetch.fsckObjects:
error: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes
fatal: Error in object
fatal: index-pack failed
Now with fetch.fsck.zeroPaddedFilemode=warn we'll warn about that
issue, but the clone will succeed:
warning: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes
warning: object a18c4d13c2a5fa2d4ecd5346c50e119b999b807d: zeroPaddedFilemode: contains zero-padded file modes
warning: object 84df066176c8da3fd59b13731a86d90f4f1e5c9d: zeroPaddedFilemode: contains zero-padded file modes
The motivation for this is to be able to turn on fetch.fsckObjects
globally across a fleet of computers but still be able to manually
clone various legacy repositories by either white-listing specific
issues, or better yet whitelist specific objects.
The use of --git-dir=* instead of -C in the tests could be considered
somewhat archaic, but the tests I'm adding here are duplicating the
corresponding receive.* tests with as few changes as possible.

Change the transfer.fsckObjects documentation to explicitly note the
unique security and/or corruption issues fetch.fsckObjects suffers
from, since it doesn't have a quarantine environment.
This was already alluded to in the existing documentation, but let's
spell it out so there's no confusion here, and give a concrete example
of how to work around this limitation.
Let's also prominently note that this is considered to be a limitation
of the current implementation, rather than something that's intended
and by design, since we might change this in the future.

doing were basic reachability sanity checks, but that hasn't been true
for a very long time. Update the description to match reality, and

The documentation for the fsck.<msg-id> and receive.fsck.<msg-id>
variables was mostly duplicated in two places, with fsck.<msg-id>
making no mention of the corresponding receive.fsck.<msg-id>, and the
same for fsck.skipList.
I spent quite a lot of time today wondering why setting the
fsck.<msg-id> variant wasn't working to clone a legacy repository (not
that that would have worked anyway, but a subsequent patch implements
fetch.fsck.<msg-id>).
Rectify this situation by describing the feature in general terms
under the fsck.* documentation, and make the receive.fsck.*
documentation refer to those variables instead.
This documentation was initially added in 2becf00ff7 ("fsck: support
demoting errors to warnings", 2015-06-22) and 4b55b9b479 ("fsck:

We can already disable replace refs using a command line
option or environment variable, but those are awkward to
apply universally. Let's add a config option to do the same
thing.
That raises the question of why one might want to do so
universally. The answer is that replace refs violate the
immutability of objects. For instance, if you wanted to
cache the diff between commit XYZ and its parent, then in
theory that never changes; the hash XYZ represents the total
state. But replace refs violate that; pushing up a new ref
may create a completely new diff.
The obvious "if it hurts, don't do it" answer is not to
create replace refs if you're doing this kind of caching.
But for a site hosting arbitrary repositories, they may want
to allow users to share replace refs with each other, but
not actually respect them on the site (because the caching
is more important than the replace feature).

Introduce a new negotiation algorithm used during fetch that skips
commits in an effort to find common ancestors faster. The skips grow
similarly to the Fibonacci sequence as the commit walk proceeds further
away from the tips. The skips may cause unnecessary commits to be
included in the packfile, but the negotiation step typically ends more
quickly.
Usage of this algorithm is guarded behind the configuration flag

The current description of "core.ignoreCase" reads like an option which
is intended to be changed by the user while it's actually expected to
be set by Git on initialization only. Subsequently, Git relies on the
proper configuration of this variable, as noted by Bryan Turner [1]:
Git on a case-insensitive filesystem (APFS, HFS+, FAT32, exFAT,
vFAT, NTFS, etc.) is not designed to be run with anything other
than core.ignoreCase=true.

Currently, while performing packfile negotiation, clients are only
allowed to specify their desired objects using object ids. This causes
a vulnerability to failure when an object turns non-existent during
negotiation, which may happen if, for example, the desired repository is
provided by multiple Git servers in a load-balancing arrangement and
there exists replication delay.
In order to eliminate this vulnerability, implement the ref-in-want
feature for the 'fetch' command in protocol version 2. This feature
enables the 'fetch' command to support requests in the form of ref names
through a new "want-ref <ref>" parameter. At the conclusion of
negotiation, the server will send a list of all of the wanted references
(as provided by "want-ref" lines) in addition to the generated packfile.

Introduce a checkout.defaultRemote setting which can be used to
designate a remote to prefer (via checkout.defaultRemote=origin) when
running e.g. "git checkout master" to mean origin/master, even though
there's other remotes that have the "master" branch.
I want this because it's very handy to use this workflow to checkout a
repository and create a topic branch, then get back to a "master" as
retrieved from upstream:
(
cd /tmp &&
rm -rf tbdiff &&
git clone git@github.com:trast/tbdiff.git &&
cd tbdiff &&
git branch -m topic &&
git checkout master
)
That will output:
Branch 'master' set up to track remote branch 'master' from 'origin'.
Switched to a new branch 'master'
But as soon as a new remote is added (e.g. just to inspect something
from someone else) the DWIMery goes away:
(
cd /tmp &&
rm -rf tbdiff &&
git clone git@github.com:trast/tbdiff.git &&
cd tbdiff &&
git branch -m topic &&
git remote add avar git@github.com:avar/tbdiff.git &&
git fetch avar &&
git checkout master
)
Will output (without the advice output added earlier in this series):
error: pathspec 'master' did not match any file(s) known to git.
The new checkout.defaultRemote config allows me to say that whenever
that ambiguity comes up I'd like to prefer "origin", and it'll still
work as though the only remote I had was "origin".
Also adjust the advice.checkoutAmbiguousRemoteBranchName message to
mention this new config setting to the user, the full output on my
git.git is now (the last paragraph is new):
$ ./git --exec-path=$PWD checkout master
error: pathspec 'master' did not match any file(s) known to git.
hint: 'master' matched more than one remote tracking branch.
hint: We found 26 remotes with a reference that matched. So we fell back
hint: on trying to resolve the argument as a path, but failed there too!
hint:
hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
hint: you can do so by fully qualifying the name with the --track option:
hint:
hint: git checkout --track origin/<name>
hint:
hint: If you'd like to always have checkouts of an ambiguous <name> prefer
hint: one remote, e.g. the 'origin' remote, consider setting
hint: checkout.defaultRemote=origin in your config.
I considered splitting this into checkout.defaultRemote and
worktree.defaultRemote, but it's probably less confusing to break our
own rules that anything shared between config should live in core.*
than have two config settings, and I couldn't come up with a short
name under core.* that made sense (core.defaultRemoteForCheckout?).

exactly one remote (call it <remote>) with a matching name, treat
as equivalent to [...] <remote>/<branch.
This is a really useful feature. The problem is that when you add
another remote (e.g. a fork), git won't find a unique branch name
anymore, and will instead print this unhelpful message:
$ git checkout master
error: pathspec 'master' did not match any file(s) known to git
Now it will, on my git.git checkout, print:
$ ./git --exec-path=$PWD checkout master
error: pathspec 'master' did not match any file(s) known to git.
hint: 'master' matched more than one remote tracking branch.
hint: We found 26 remotes with a reference that matched. So we fell back
hint: on trying to resolve the argument as a path, but failed there too!
hint:
hint: If you meant to check out a remote tracking branch on, e.g. 'origin',
hint: you can do so by fully qualifying the name with the --track option:
hint:
hint: git checkout --track origin/<name>
Note that the "error: pathspec[...]" message is still printed. This is
because whatever else checkout may have tried earlier, its final
fallback is to try to resolve the argument as a path. E.g. in this
case:
$ ./git --exec-path=$PWD checkout master pu
error: pathspec 'master' did not match any file(s) known to git.
error: pathspec 'pu' did not match any file(s) known to git.
There we don't print the "hint:" implicitly due to earlier logic
around the DWIM fallback. That fallback is only used if it looks like
we have one argument that might be a branch.
I can't think of an intrinsic reason for why we couldn't in some
future change skip printing the "error: pathspec[...]" error. However,
to do so we'd need to pass something down to checkout_paths() to make
it suppress printing an error on its own, and for us to be confident
that we're not silencing cases where those errors are meaningful.
I don't think that's worth it since determining whether that's the
case could easily change due to future changes in the checkout logic.

The list of commands with their various attributes were spread
across a few places in the build procedure, but it now is getting a
bit more consolidated to allow more automation.
* nd/command-list:
completion: allow to customize the completable command list
completion: add and use --list-cmds=alias
completion: add and use --list-cmds=nohelpers
Move declaration for alias.c to alias.h
completion: reduce completable command list
completion: let git provide the completable command list
command-list.txt: documentation and guide line
help: use command-list.txt for the source of guides
help: add "-a --verbose" to list all commands with synopsis
git: support --list-cmds=list-<category>
completion: implement and use --list-cmds=main,others
git --list-cmds: collect command list in a string_list
git.c: convert --list-* to --list-cmds=*
Remove common-cmds.h
help: use command-list.h for common command list
generate-cmds.sh: export all commands to command-list.h
generate-cmds.sh: factor out synopsis extract code

"git blame" learns to unhighlight uninteresting metadata from the
originating commit on lines that are the same as the previous one,
and also paint lines in different colors depending on the age of
the commit.
* sb/blame-color:
builtin/blame: add new coloring scheme config
builtin/blame: highlight recently changed lines
builtin/blame: dim uninteresting metadata lines
|
|
"git status" learned to honor a new status.renames configuration to
skip rename detection, which could be useful for those who want to
do so without disabling the default rename detection done by the
"git diff" command.
* bp/status-rename-config:
add status config and command line options for rename detection

"git rebase" learned "--rebase-merges" to transplant the whole
topology of commit graph elsewhere.
* js/rebase-recreate-merge:
rebase -i --rebase-merges: add a section to the man page
rebase -i: introduce --rebase-merges=[no-]rebase-cousins
pull: accept --rebase=merges to recreate the branch topology
rebase --rebase-merges: avoid "empty merges"
sequencer: handle post-rewrite for merge commands
sequencer: make refs generated by the `label` command worktree-local
rebase --rebase-merges: add test for --keep-empty
rebase: introduce the --rebase-merges option
rebase-helper --make-script: introduce a flag to rebase merges
sequencer: fast-forward `merge` commands, if possible
sequencer: introduce the `merge` command
sequencer: introduce new commands to reset the revision
git-rebase--interactive: clarify arguments
sequencer: offer helpful advice when a command was rescheduled
sequencer: refactor how original todo list lines are accessed
sequencer: make rearrange_squash() a bit more obvious
sequencer: avoid using errno clobbered by rollback_lock_file()
