revset: raise RepoLookupError to make present() predicate continue the query
Before this patch, "bookmark()", "named()" and "tag()" predicates
raise "Abort", when the specified pattern doesn't match against
existing ones.
This prevents "present()" predicate from continuing the query, because
it only catches "RepoLookupError".
This patch raises "RepoLookupError" instead of "Abort", to make
"present()" predicate continue the query, even if "bookmark()",
"named()" or "tag()" in the sub-query of it are aborted.
This patch doesn't contain raising "RepoLookupError" for "re:" pattern
in "tag()", because "tag()" treats it differently from others. Actions
of each predicates at failure of pattern matching can be summarized as
below:
predicate "literal:" "re:"
---------- ----------- ------------
bookmark abort abort
named abort abort
tag abort continue (*1)
branch abort continue (*2)
---------- ----------- ------------
"tag()" may have to abort in the (*1) case for similarity, but this
change may break backward compatibility of existing revset queries. It
seems to have to be changed on "default" branch (with "BC" ?).
On the other hand, (*2) seems to be reasonable, even though it breaks
similarity, because "branch()" in this case doesn't check exact
existence of branches, but does pick up revisions of which branch
matches against the pattern.
This patch also adds tests for "branch()" to clarify behavior around
"present()" of similar predicates, even though this patch doesn't
change "branch()".
