builtin/remote.c: show progress when renaming remote references When renaming a remote, Git needs to rename all remote tracking references to the remote's new name (e.g., renaming "refs/remotes/old/foo" to "refs/remotes/new/foo" when renaming a remote from "old" to "new"). This can be somewhat slow when there are many references to rename, since each rename is done in a separate call to rename_ref() as opposed to grouping all renames together into the same transaction. It would be nice to execute all renames as a single transaction, but there is a snag: the reference transaction backend doesn't support renames during a transaction (only individually, via rename_ref()). The reasons there are described in more detail in [1], but the main problem is that in order to preserve the existing reflog, it must be moved while holding both locks (i.e., on "oldname" and "newname"), and the ref transaction code doesn't support inserting arbitrary actions into the middle of a transaction like that. As an aside, adding support for this to the ref transaction code is less straightforward than inserting both a ref_update() and ref_delete() call into the same transaction. rename_ref()'s special handling to detect D/F conflicts would need to be rewritten for the transaction code if we wanted to proactively catch D/F conflicts when renaming a reference during a transaction. The reftable backend could support this much more readily because of its lack of D/F conflicts. Instead of a more complex modification to the ref transaction code, display a progress meter when running verbosely in order to convince the user that Git is doing work while renaming a remote. This is mostly done as-expected, with the minor caveat that we intentionally count symrefs renames twice, since renaming a symref takes place over two separate calls (one to delete the old one, and another to create the new one).

DESCRIPTION
-----------
Manage the set of repositories ("remotes") whose branches you track.
OPTIONS
-------
-v::
--verbose::
Be a little more verbose and show remote url after name.
NOTE: This must be placed between `remote` and subcommand.
COMMANDS
--------
With no arguments, shows a list of existing remotes. Several
subcommands are available to perform operations on the remotes.
'add'::
Add a remote named <name> for the repository at
<URL>. The command `git fetch <name>` can then be used to create and
update remote-tracking branches <name>/<branch>.
+
With `-f` option, `git fetch <name>` is run immediately after
the remote information is set up.
+
With `--tags` option, `git fetch <name>` imports every tag from the
remote repository.
+
With `--no-tags` option, `git fetch <name>` does not import tags from
the remote repository.
+
By default, only tags on fetched branches are imported
(see linkgit:git-fetch[1]).
+
With `-t <branch>` option, instead of the default glob
refspec for the remote to track all branches under
the `refs/remotes/<name>/` namespace, a refspec to track only `<branch>`
is created. You can give more than one `-t <branch>` to track
multiple branches without grabbing all branches.
+
With `-m <master>` option, a symbolic-ref `refs/remotes/<name>/HEAD` is set
up to point at remote's `<master>` branch. See also the set-head command.

docs: stop using asciidoc no-inline-literal In asciidoc 7, backticks like `foo` produced a typographic effect, but did not otherwise affect the syntax. In asciidoc 8, backticks introduce an "inline literal" inside which markup is not interpreted. To keep compatibility with existing documents, asciidoc 8 has a "no-inline-literal" attribute to keep the old behavior. We enabled this so that the documentation could be built on either version. It has been several years now, and asciidoc 7 is no longer in wide use. We can now decide whether or not we want inline literals on their own merits, which are: 1. The source is much easier to read when the literal contains punctuation. You can use `master~1` instead of `master{tilde}1`. 2. They are less error-prone. Because of point (1), we tend to make mistakes and forget the extra layer of quoting. This patch removes the no-inline-literal attribute from the Makefile and converts every use of backticks in the documentation to an inline literal (they must be cleaned up, or the example above would literally show "{tilde}" in the output). Problematic sites were found by grepping for '`.*[{\\]' and examined and fixed manually. The results were then verified by comparing the output of "html2text" on the set of generated html pages. Doing so revealed that in addition to making the source more readable, this patch fixes several formatting bugs: - HTML rendering used the ellipsis character instead of literal "..." in code examples (like "git log A...B") - some code examples used the right-arrow character instead of '->' because they failed to quote - api-config.txt did not quote tilde, and the resulting HTML contained a bogus snippet like: <tt><sub></tt> foo <tt></sub>bar</tt> which caused some parsers to choke and omit whole sections of the page. - git-commit.txt confused ``foo`` (backticks inside a literal) with ``foo'' (matched double-quotes) - mentions of `A U Thor <author@example.com>` used to erroneously auto-generate a mailto footnote for author@example.com - the description of --word-diff=plain incorrectly showed the output as "[-removed-] and {added}", not "{+added+}". - using "prime" notation like: commit `C` and its replacement `C'` confused asciidoc into thinking that everything between the first backtick and the final apostrophe were meant to be inside matched quotes - asciidoc got confused by the escaping of some of our asterisks. In particular, `credential.\*` and `credential.<url>.\*` properly escaped the asterisk in the first case, but literally passed through the backslash in the second case.

When a fetch mirror is created with `--mirror=fetch`, the refs will not
remote: separate the concept of push and fetch mirrors git-remote currently has one option, "--mirror", which sets up mirror configuration which can be used for either fetching or pushing. It looks like this: [remote "mirror"] url = wherever fetch = +refs/*:refs/* mirror = true However, a remote like this can be dangerous and confusing. Specifically: 1. If you issue the wrong command, it can be devastating. You are not likely to "push" when you meant to "fetch", but "git remote update" will try to fetch it, even if you intended the remote only for pushing. In either case, the results can be quite destructive. An unintended push will overwrite or delete remote refs, and an unintended fetch can overwrite local branches. 2. The tracking setup code can produce confusing results. The fetch refspec above means that "git checkout -b new master" will consider refs/heads/master to come from the remote "mirror", even if you only ever intend to push to the mirror. It will set up the "new" branch to track mirror's refs/heads/master. 3. The push code tries to opportunistically update tracking branches. If you "git push mirror foo:bar", it will see that we are updating mirror's refs/heads/bar, which corresponds to our local refs/heads/bar, and will update our local branch. To solve this, we split the concept into "push mirrors" and "fetch mirrors". Push mirrors set only remote.*.mirror, solving (2) and (3), and making an accidental fetch write only into FETCH_HEAD. Fetch mirrors set only the fetch refspec, meaning an accidental push will not force-overwrite or delete refs on the remote end. The new syntax is "--mirror=<fetch|push>". For compatibility, we keep "--mirror" as-is, setting up both types simultaneously. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

be stored in the 'refs/remotes/' namespace, but rather everything in
'refs/' on the remote will be directly mirrored into 'refs/' in the
local repository. This option only makes sense in bare repositories,
because a fetch would overwrite any local commits.

When a push mirror is created with `--mirror=push`, then `git push`
will always behave as if `--mirror` was passed.
'rename'::
Rename the remote named <old> to <new>. All remote-tracking branches and
configuration settings for the remote are updated.
+
In case <old> and <new> are the same, and <old> is a file under
`$GIT_DIR/remotes` or `$GIT_DIR/branches`, the remote is converted to
the configuration file format.
'remove'::
'rm'::
Remove the remote named <name>. All remote-tracking branches and
configuration settings for the remote are removed.
'set-head'::
Sets or deletes the default branch (i.e. the target of the
symbolic-ref `refs/remotes/<name>/HEAD`) for
the named remote. Having a default branch for a remote is not required,
but allows the name of the remote to be specified in lieu of a specific
branch. For example, if the default branch for `origin` is set to
`master`, then `origin` may be specified wherever you would normally
specify `origin/master`.
+
With `-d` or `--delete`, the symbolic ref `refs/remotes/<name>/HEAD` is deleted.
+
With `-a` or `--auto`, the remote is queried to determine its `HEAD`, then the
symbolic-ref `refs/remotes/<name>/HEAD` is set to the same branch. e.g., if the remote
`HEAD` is pointed at `next`, `git remote set-head origin -a` will set
the symbolic-ref `refs/remotes/origin/HEAD` to `refs/remotes/origin/next`. This will
only work if `refs/remotes/origin/next` already exists; if not it must be
fetched first.
+
Use `<branch>` to set the symbolic-ref `refs/remotes/<name>/HEAD` explicitly. e.g., `git
remote set-head origin master` will set the symbolic-ref `refs/remotes/origin/HEAD` to
`refs/remotes/origin/master`. This will only work if
`refs/remotes/origin/master` already exists; if not it must be fetched first.
+
'set-branches'::
Changes the list of branches tracked by the named remote.
This can be used to track a subset of the available remote branches
after the initial setup for a remote.
+
The named branches will be interpreted as if specified with the
`-t` option on the `git remote add` command line.
+
With `--add`, instead of replacing the list of currently tracked
branches, adds to that list.
'get-url'::
Retrieves the URLs for a remote. Configurations for `insteadOf` and
`pushInsteadOf` are expanded here. By default, only the first URL is listed.
+
With `--push`, push URLs are queried rather than fetch URLs.
+
With `--all`, all URLs for the remote will be listed.
'set-url'::
Changes URLs for the remote. Sets first URL for remote <name> that matches
regex <oldurl> (first URL if no <oldurl> is given) to <newurl>. If
<oldurl> doesn't match any URL, an error occurs and nothing is changed.
+
With `--push`, push URLs are manipulated instead of fetch URLs.
+
With `--add`, instead of changing existing URLs, new URL is added.
+
With `--delete`, instead of changing existing URLs, all URLs matching
regex <URL> are deleted for remote <name>. Trying to delete all
non-push URLs is an error.
+
Note that the push URL and the fetch URL, even though they can
be set differently, must still refer to the same place. What you
pushed to the push URL should be what you would see if you
immediately fetched from the fetch URL. If you are trying to
fetch from one place (e.g. your upstream) and push to another (e.g.
your publishing repository), use two separate remotes.
'show'::
Gives some information about the remote <name>.
+
With `-n` option, the remote heads are not queried first with
`git ls-remote <name>`; cached information is used instead.
'prune'::
Deletes stale references associated with <name>. By default, stale
remote-tracking branches under <name> are deleted, but depending on
global configuration and the configuration of the remote we might even
prune local tags that haven't been pushed there. Equivalent to `git
fetch --prune <name>`, except that no new references will be fetched.
+
See the PRUNING section of linkgit:git-fetch[1] for what it'll prune
depending on various configuration.
+
With `--dry-run` option, report what branches would be pruned, but do not
actually prune them.
'update'::
Fetch updates for remotes or remote groups in the repository as defined by
`remotes.<group>`. If neither group nor remote is specified on the command line,
the configuration parameter remotes.default will be used; if
remotes.default is not defined, all remotes which do not have the
configuration parameter `remote.<name>.skipDefaultUpdate` set to true will
be updated. (See linkgit:git-config[1]).
+
With `--prune` option, run pruning against all the remotes that are updated.
DISCUSSION
----------
The remote configuration is achieved using the `remote.origin.url` and
`remote.origin.fetch` configuration variables. (See
linkgit:git-config[1]).
remote: add meaningful exit code on missing/existing Change the exit code for the likes of "git remote add/rename" to exit with 2 if the remote in question doesn't exist, and 3 if it does. Before we'd just die() and exit with the general 128 exit code. This changes the output message from e.g.: fatal: remote origin already exists. To: error: remote origin already exists. Which I believe is a feature, since we generally use "fatal" for the generic errors, and "error" for the more specific ones with a custom exit code, but this part of the change may break code that already relies on stderr parsing (not that we ever supported that...). The motivation for this is a discussion around some code in GitLab's gitaly which wanted to check this, and had to parse stderr to do so: https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2695 It's worth noting as an aside that a method of checking this that doesn't rely on that is to check with "git config" whether the value in question does or doesn't exist. That introduces a TOCTOU race condition, but on the other hand this code (e.g. "git remote add") already has a TOCTOU race. We go through the config.lock for the actual setting of the config, but the pseudocode logic is: read_config(); check_config_and_arg_sanity(); save_config(); So e.g. if a sleep() is added right after the remote_is_configured() check in add() we'll clobber remote.NAME.url, and add another (usually duplicate) remote.NAME.fetch entry (and other values, depending on invocation).

EXIT STATUS
-----------
On success, the exit status is `0`.
When subcommands such as 'add', 'rename', and 'remove' can't find the
remote in question, the exit status is `2`. When the remote already
exists, the exit status is `3`.
On any other error, the exit status may be any other non-zero value.
EXAMPLES
--------
* Add a new remote, fetch, and check out a branch from it
+
------------
$ git remote
origin
$ git branch -r
origin/HEAD -> origin/master
origin/master
$ git remote add staging git://git.kernel.org/.../gregkh/staging.git
$ git remote
origin
staging
$ git fetch staging
...
From git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
* [new branch] master -> staging/master
* [new branch] staging-linus -> staging/staging-linus
* [new branch] staging-next -> staging/staging-next
$ git branch -r
origin/HEAD -> origin/master
origin/master
staging/master
staging/staging-linus
staging/staging-next
$ git switch -c staging staging/master
...
------------
* Imitate 'git clone' but track only selected branches
+
------------
$ mkdir project.git
$ cd project.git
$ git init
$ git remote add -f -t master -m master origin git://example.com/git.git/
$ git merge origin
