sqliterevmap: break ".hashes()" cycle in a safer way
The `fromsvn()` revset implementation could cause weakref error when using
sqliterevmap like:
File "hgsubversion/util.py", line 357, in <lambda>
return subset.filter(lambda r: tonode(r) in hashes)
File "hgsubversion/maps.py", line 542, in __contains__
return self.get(key) != None
File "hgsubversion/maps.py", line 533, in get
for row in self.revmap._query(
ReferenceError: weakly-referenced object no longer exists
Basically the seemingly harmless assignment could break surprisingly:
# dangerous: `hashes` does not have a reference of `meta.revmap` and may
# become unavailable after `meta`, `revmap` being released by refcount.
hashes = meta.revmap.hashes()
The above syntax is nice to support while avoiding cycles is also nice.
This patch removes `revmap._hashes` so the revmap no longer owns a reference
of a `ReverseRevMap` object so the `ReverseRevMap` object no longer needs to
use weakref for `self.revmap`.
This could actually be caught by `comprehensive/test_sqlite_revmap.py`.
I was not careful enough verifying the "fromsvn()" patch.
