After performing a merge that has conflicts git status will, by default,
attempt to detect renames which causes many objects to be examined. In a
virtualized repo, those objects do not exist locally so the rename logic
triggers them to be fetched from the server. This results in the status call
taking hours to complete on very large repos vs seconds with this patch.
Add a new config status.renames setting to enable turning off rename
detection during status and commit. This setting will default to the value
of diff.renames.
Add a new config status.renamelimit setting to to enable bounding the time
spent finding out inexact renames during status and commit. This setting
will default to the value of diff.renamelimit.
Add --no-renames command line option to status that enables overriding the
config setting from the command line. Add --find-renames[=<n>] command line
option to status that enables detecting renames and optionally setting the
similarity index.

Originally I had planned to have the temperature cool down dependent on
the age of the project or file for example, as that might scale better,
but that can be added on top of this commit, e.g. instead of giving a
date, you could imagine giving a percentage that would be the linearly
interpolated between now and the beginning of the file.
Similarly to the previous patch, this offers the command line option
'--color-by-age' to enable this mode and the config option
'color.blame.highlightrecent' to select colors. A later patch will offer

When using git-blame lots of lines contain redundant information, for
example in hunks that consist of multiple lines, the metadata (commit
name, author, date) are repeated. A reader may not be interested in those,
so offer an option to color the information that is repeated from the
previous line differently. Traditionally, we use CYAN for lines that
are less interesting than others (e.g. hunk header), so go with that.
The command line option '--color-lines' will trigger the coloring of
repeated lines, and the config option 'color.blame.colorLines' is
provided to select the color. Setting the config option doesn't imply
that repeated lines are colored. A later patch will introduce a config
to enable this mode by default.

This config allows us to keep <N> packs back if their size is larger
than a limit. But if this N >= gc.autoPackLimit, we may have a
problem. We are supposed to reduce the number of packs after a
threshold because it affects performance.
We could tell the user that they have incompatible gc.bigPackThreshold
and gc.autoPackLimit, but it's kinda hard when 'git gc --auto' runs in
background. Instead let's fall back to the next best stategy: try to
reduce the number of packs anyway, but keep the base pack out. This
reduces the number of packs to two and hopefully won't take up too
much resources to repack (the assumption still is the base pack takes
most resources to handle).

When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12,
2017-12-08), it was guarded by the uploadpack.allowFilter config item
to allow server operators to control when they start supporting it.
That config item didn't go far enough, though: it controls whether the
'filter' capability is advertised, but if a (custom) client ignores
the capability advertisement and passes a filter specification anyway,
the server would handle that despite allowFilter being false.
This is particularly significant if a security bug is discovered in
this new experimental partial clone code. Installations without
uploadpack.allowFilter ought not to be affected since they don't
intend to support partial clone, but they would be swept up into being
vulnerable.
Simplify and limit the attack surface by making uploadpack.allowFilter
disable the feature, not just the advertisement of it.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.
See my "Re: [BUG] git remote prune removes local tags, depending on
fetch config" (87po6ahx87.fsf@evledraar.gmail.com;

When a graphical GIT_EDITOR is spawned by a Git command that opens

might be obscured by other windows. The user might be left staring at
the original Git terminal window without even realizing that s/he needs
to interact with another window before Git can proceed. To this user Git
appears hanging.
Print a message that Git is waiting for editor input in the original
terminal and get rid of it when the editor returns, if the terminal
supports erasing the last line. Also, make sure that our message is
terminated with a whitespace so that any message the editor may show
upon starting up will be kept separate from our message.
Power users might not want to see this message or their editor might
already print such a message (e.g. emacsclient). Allow these users to
suppress the message by disabling the "advice.waitingForEditor" config.
The standard advise() function is not used here as it would always add

Android's "repo" tool is a tool for managing a large codebase
consisting of multiple smaller repositories, similar to Git's

The cause: when it encounters ssh:// URLs, repo pre-connects to the
server and sets GIT_SSH to a helper ".repo/repo/git_ssh" that reuses
that connection. Before 94b8ae5a, the helper was assumed to support
OpenSSH options for lack of a better guess and got passed a -p option
to set the port. After that patch, it uses the new default of a
simple helper that does not accept an option to set the port.
The next release of "repo" will set GIT_SSH_VARIANT to "ssh" to avoid
that. But users of old versions and of other similar GIT_SSH
implementations would not get the benefit of that fix.
So update the default to use OpenSSH options again, with a twist. As
observed in 94b8ae5a, we cannot assume that $GIT_SSH always handles
OpenSSH options: common helpers such as travis-ci's dpl[*] are
configured using GIT_SSH and do not accept OpenSSH options. So make
the default a new variant "auto", with the following behavior:
1. First, check for a recognized basename, like today.
2. If the basename is not recognized, check whether $GIT_SSH supports
OpenSSH options by running
$GIT_SSH -G <options> <host>
This returns status 0 and prints configuration in OpenSSH if it
recognizes all <options> and returns status 255 if it encounters
an unrecognized option. A wrapper script like
exec ssh -- "$@"
would fail with
ssh: Could not resolve hostname -g: Name or service not known
, correctly reflecting that it does not support OpenSSH options.
The command is run with stdin, stdout, and stderr redirected to
/dev/null so even a command that expects a terminal would exit
immediately.
3. Based on the result from step (2), behave like "ssh" (if it
succeeded) or "simple" (if it failed).
This way, the default ssh variant for unrecognized commands can handle
both the repo and dpl cases as intended.
This autodetection has been running on Google workstations since
2017-10-23 with no reported negative effects.
