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.

Some users like to set `remote.origin.prune = true` in their ~/.gitconfig
so that all of their repositories use that default.
However, our code is ill-prepared for this, mistaking that single entry to
mean that there is already a remote of the name "origin", even if there is
not.
This patch adds a test case demonstrating this issue.

Thanks. Here it is rolled up with a commit message.

Subject: clear_delta_base_cache(): don't modify hashmap while iterating
Removing entries while iterating causes fast-import to
access an already-freed `struct packed_git`, leading to
various confusing errors.
What happens is that clear_delta_base_cache() drops the
whole contents of the cache by iterating over the hashmap,
calling release_delta_base_cache() on each entry. That
function removes the item from the hashmap. The hashmap code
may then shrink the table, but the hashmap_iter struct
retains an offset from the old table.
As a result, the next call to hashmap_iter_next() may claim
that the iteration is done, even though some items haven't
been visited.
The only caller of clear_delta_base_cache() is fast-import,
which wants to clear the cache because it is discarding the
packed_git struct for its temporary pack. So by failing to
remove all of the entries, we still have references to the
freed packed_git.
To make things even more confusing, this doesn't seem to
trigger with the test suite, because it depends on
complexities like the size of the hash table, which entries
got cleared, whether we try to access them before they're
evicted from the cache, etc.
So I've been able to identify the problem with large
imports like freebsd's svn import, or a fast-export of
linux.git. But nothing that would be reasonable to run as
part of the normal test suite.
We can fix this easily by iterating over the lru linked list
instead of the hashmap. They both contain the same entries,
and we can use the "safe" variant of the list iterator,
which exists for exactly this case.
Let's also add a warning to the hashmap API documentation to
reduce the chances of getting bit by this again.

series: v3 was sent out with these changes, as requested by the

- reworded the comment about "recycling handles"
- moved the reassignment of the `console` variable before the dup2()
call so that it is valid at all times
- removed the "handle = INVALID_HANDLE_VALUE" assignment, as the local
variable `handle` is not used afterwards anyway

Adding --format to git tag -v mutes the default output of the GPG
verification and instead prints the formatted tag object.
This allows callers to cross-check the tagname from refs/tags with
the tagname from the tag object header upon GPG verification.
The callback function for for_each_tag_name() didn't allow callers to
pass custom data to their callback functions. Add a new opaque pointer
to each_tag_name_fn's parameter to allow this.
