"git range-diff" segfaulted when diff.noprefix configuration was
used, as it blindly expected the patch it internally generates to
have the standard a/ and b/ prefixes. The command now forces the

by any end-user configuration.

The rename detection logic sorts a list of rename source candidates
by similarity to pick the best candidate, which means that a tie
between sources with the same similarity is broken by the original
location in the original candidate list (which is sorted by path).

not promised by system supplied qsort(3), to ensure consistent
results across platforms.

In commit 8e4ec337 ("merge-recursive: fix the diff3 common ancestor
label for virtual commits", 2019-10-01), which was a fix to commit
743474cbfa8b ("merge-recursive: provide a better label for diff3
common ancestor", 2019-08-17), the label for the common ancestor was
changed from always being
"merged common ancestors"
to instead be based on the number of merge bases and whether the merge
base was a real commit or a virtual one:
>=2: "merged common ancestors"
1, via merge_recursive_generic: "constructed merge base"
1, otherwise: <abbreviated commit hash>
0: "<empty tree>"
The handling for "constructed merge base" worked by allowing
opt->ancestor to be set in merge_recursive_generic(), so we paid
attention to the setting of that variable in merge_recursive_internal().
Now, for the outer merge, the code flow was simply the following:
ancestor_name = "merged merge bases"
loop over merge_bases: merge_recursive_internal()
The first merge base not needing recursion would determine its own
ancestor_name however necessary and thus run
ancestor_name = $SOMETHING
empty loop over merge_bases...
opt->ancestor = ancestor_name
merge_trees_internal()
Now, the next set of merge_bases that would need to be merged after this
particular merge had completed would note that opt->ancestor has been
set to something (to a local ancestor_name variable that has since been
popped off the stack), and thus it would run:
... else if (opt->ancestor) {
ancestor_name = opt->ancestor; /* OOPS! */
loop over merge_bases: merge_recursive_internal()
opt->ancestor = ancestor_name
merge_trees_internal()
This resulted in garbage strings being printed for the virtual merge
bases, which was visible in git.git by just merging commit b744c3af07
into commit 6d8cb22a4f. There are two ways to fix this: set
opt->ancestor to NULL after using it to avoid re-use, or add a
!opt->priv->call_depth check to the if block for using a pre-defined
opt->ancestor. Apply both fixes.
