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.

The "--format=..." option "git for-each-ref" takes learned to show
the name of the 'remote' repository and the ref at the remote side
that is affected for 'upstream' and 'push' via "%(push:remotename)"
and friends.
* js/for-each-ref-remote-name-and-ref:
for-each-ref: test :remotename and :remoteref
for-each-ref: let upstream/push report the remote ref name
for-each-ref: let upstream/push optionally report the remote name
There are times when scripts want to know not only the name of the
push branch on the remote, but also the name of the branch as known
by the remote repository.
An example of this is when a tool wants to push to the very same branch
from which it would pull automatically, i.e. the `<remote>` and the `<to>`
in `git push <remote> <from>:<to>` would be provided by
`%(upstream:remotename)` and `%(upstream:remoteref)`, respectively.
This patch offers the new suffix :remoteref for the `upstream` and `push`
atoms, allowing to show exactly that. Example:
$ cat .git/config
...
[remote "origin"]
url = https://where.do.we.come/from
fetch = refs/heads/*:refs/remote/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
[branch "develop/with/topics"]
remote = origin
merge = refs/heads/develop/with/topics
...
$ git for-each-ref \

When using the hashmap a common need is to have access to caller provided
data in the compare function. A couple of times we abuse the keydata field
to pass in the data needed. This happens for example in patch-ids.c.
This patch changes the function signature of the compare function
to have one more void pointer available. The pointer given for each
invocation of the compare function must be defined in the init function
of the hashmap and is just passed through.
Documentation of this new feature is deferred to a later patch.
This is a rather mechanical conversion, just adding the new pass-through
parameter. However while at it improve the naming of the fields of all
compare functions used by hashmaps by ensuring unused parameters are
prefixed with 'unused_' and naming the parameters what they are (instead
of 'unused' make it 'unused_keydata').

We already have free_refspec(), a public function which does
the same thing as the static free_refspecs(). Let's just
keep one. There are two minor differences between the
functions:
1. free_refspecs() is a noop when the refspec argument is
NULL. This probably doesn't matter in practice. The
nr_refspec parameter would presumably be 0 in that
case, skipping the loop. And free(NULL) is explicitly
OK. But it doesn't hurt for us to port this extra
safety to free_refspec(), as one of the callers passes
a funny "i+1" count.
2. The order of arguments is reversed between the two
functions. This patch uses the already-public order of
free_refspec(), as it matches the argument order on the
parsing side.

On Windows, the remote repository name in, e.g., `git fetch foo\bar`

the function valid_remote_nick() does not account for backslashes.
Use is_dir_sep() to check for both slashes and backslashes on Windows.
This was discovered while playing with Duy's patches that warn after
fopen() failures. The functions that read the branches and remotes
files are protected by a valid_remote_nick() check. Without this
change, a Windows style absolute path is incorrectly regarded as
nickname and is concatenated to a prefix and used with fopen(). This
triggers warnings because a colon in a path name is not allowed:

"git ls-remote" and "git archive --remote" are designed to work
without being in a directory under Git's control. However, recent
updates revealed that we randomly look into a directory called
.git/ without actually doing necessary set-up when working in a
repository. Stop doing so.
* jn/remote-helpers-with-git-dir:
remote helpers: avoid blind fall-back to ".git" when setting GIT_DIR
remote: avoid reading $GIT_DIR config in non-repo
The "git ls-remote" command can be run outside of a
repository, but needs to look up configured remotes. The
config code is smart enough to handle this case itself, but
we also check the historical "branches" and "remotes" paths
in $GIT_DIR. The git_path() function causes us to blindly
look at ".git/remotes", even if we know we aren't in a git
repository.
For now, this is just an unlikely bug (you probably don't
have such a file if you're not in a repository), but it will
become more obvious once we merge b1ef400ee (setup_git_env:
avoid blind fall-back to ".git", 2016-10-20):
[now]
$ git ls-remote
fatal: No remote configured to list refs from.
[with b1ef400ee]
$ git ls-remote
fatal: BUG: setup_git_env called without repository
We can fix this by skipping these sources entirely when
we're outside of a repository.
The test is a little more complex than the demonstration
above. Rather than detect the correct behavior by parsing
the error message, we can actually set up a case where the
remote name we give is a valid repository, but b1ef400ee
would cause us to die in the configuration step.
This test doesn't fail now, but it future-proofs us for the
b1ef400ee change.

"git <cmd> @{push}" on a detached HEAD used to segfault; it has
been corrected to error out with a message.
* km/branch-get-push-while-detached:
branch_get_push: do not segfault when HEAD is detached
With anticipatory tweaking for remotes defined in ~/.gitconfig
(e.g. "remote.origin.prune" set to true, even though there may or
may not actually be "origin" remote defined in a particular Git
repository), "git remote rename" and other commands misinterpreted
and behaved as if such a non-existing remote actually existed.
* js/remote-rename-with-half-configured-remote:
remote rename: more carefully determine whether a remote is configured
remote rename: demonstrate a bogus "remote exists" bug
One of the really nice features of the ~/.gitconfig file is that users
can override defaults by their own preferred settings for all of their
repositories.
One such default that some users like to override is whether the
"origin" remote gets auto-pruned or not. The user would simply call
git config --global remote.origin.prune true
and from now on all "origin" remotes would be pruned automatically when
fetching into the local repository.
There is just one catch: now Git thinks that the "origin" remote is
configured, even if the repository config has no [remote "origin"]
section at all, as it does not realize that the "prune" setting was
configured globally and that there really is no "origin" remote
configured in this repository.
That is a problem e.g. when renaming a remote to a new name, when Git
may be fooled into thinking that there is already a remote of that new
name.
Let's fix this by paying more attention to *where* the remote settings
came from: if they are configured in the local repository config, we
must not overwrite them. If they were configured elsewhere, we cannot
overwrite them to begin with, as we only write the repository config.
There is only one caller of remote_is_configured() (in `git fetch`) that
may want to take remotes into account even if they were configured
outside the repository config; all other callers essentially try to
prevent the Git command from overwriting settings in the repository
config.
To accommodate that fact, the remote_is_configured() function now
requires a parameter that states whether the caller is interested in all
remotes, or only in those that were configured in the repository config.
Many thanks to Jeff King whose tireless review helped with settling for
nothing less than the current strategy.
