[PATCHv4 0/5] Be more careful when prunning

[Carlos Martín Nieto]

Hello,

This version covers Junio's concerns about code and functionality
duplication with the third patch. The order of arguments for
get_stale_heads is not changed anymore in the fourth patch.

The first patch is not that big a deal, but it's better if we're
freeing the refspecs, we might as well free all of them.

The second patch introduces expected failures for the features that
this series fixes.

The third patch is new and moves the logic out of remote_find_tracking
into a query_refspecs function. remote_find_tracking and
apply_refspecs are both changed to be wrappers around this
function. This way, the logic is in one function instead of three
different ones.

The fourth patch changes prune_refs and get_stale_heads so the caller
has to decide which refspecs are the appropriate ones to use. For
example, running

    git fetch --prune origin refs/heads/master:refs/heads/master

doesn't remove the other branches anymore. For a more interesting (and
believable) example, let's take

    git fetch --prune origin refs/heads/b/*:refs/heads/b/*

because you want to prune the refs inside the b/ namespace
only. Currently git will delete all the refs that aren't under that
namespace. With the second patch applied, git won't remove any refs
outside the b/ namespace.

What is probably the most usual case is covered by the fifth patch,
which pretends that a "refs/tags/*:refs/tags/*" refspec was given on
the command-line. That fixes the

    git fetch --prune --tags origin

case. The non-tag refs are kept now.

Cheers,
   cmn

[PATCH 3/5] remote: separate out the remote_find_tracking logic into query_refspecs

[Carlos Martín Nieto]

Move the body of remote_find_tracking to a new function query_refspecs
which does the same (find a refspec that matches and apply the
transformation) but explicitely wants the list of refspecs.

Make remote_find_tracking and apply_refspecs use query_refspecs.

I notice that before this update, passing a refspec[] with an element that
lacks its dst side to apply_refspecs() would have segfaulted but with this
update such an element in the refspec[] will simply be ignored.

This helper function was added in 72ff894 (Allow helper to map private ref
names into normal names, 2009-11-18) for transport-helper's use. I am sure
the change will not introduce a regression due to this skippage (the code
without this patch would have simply crashed with such an input anyway),
but I thought people involved in the transport layer may want to know.

[PATCH 4/5] fetch: honor the user-provided refspecs when pruning refs

[Carlos Martín Nieto]

If the user gave us refspecs on the command line, we should use those
when deciding whether to prune a ref instead of relying on the
refspecs in the config.

Previously, running

    git fetch --prune origin refs/heads/master:refs/remotes/origin/master

would delete every other ref under the origin namespace because we
were using the refspec to filter the available refs but using the
configured refspec to figure out if a ref had been deleted on the
remote. This is clearly the wrong thing to do.

Change prune_refs and get_stale_heads to simply accept a list of
references and a list of refspecs. The caller of either function needs
to decide what refspecs should be used to decide whether a ref is
stale.

[PATCH 5/5] fetch: treat --tags like refs/tags/*:refs/tags/* when pruning

[Carlos Martín Nieto]

If --tags is specified, add that refspec to the list given to
prune_refs so it knows to treat it as a filter on what refs to
should consider for prunning. This way

    git fetch --prune --tags origin

only prunes tags and doesn't delete the branch refs.
