All 3 users of _addrevision use raw:
- addrevision: passing rawtext to _addrevision
- addgroup: passing rawtext and raw=True to _addrevision
- clone: passing rawtext to _addrevision
There is no real user using _addrevision(raw=False). On the other hand,
_addrevision is low-level code dealing with raw revlog deltas and rawtexts.
It should not transform rawtext to non-raw text.
This patch removes the "raw" parameter from "_addrevision", and does some
rename and doc change to make it clear that "_addrevision" expects rawtext.
Archeology shows 886a08012bbe added "raw" flag to "_addrevision", follow-ups
fe1e206cb389 and 1cfa6239c923 seem to make the flag unnecessary.
test-revlog-raw.py no longer complains.
See the added comment. revdiff is meant to output the raw delta that will be
written to revlog. It should use raw.
test-revlog-raw.py now shows "addgroupcopy test passed", but there is more
to fix.
Using external content provided by flagprocessor when building revlog delta
is wrong, because deltas are applied to raw contents in revlog.
This patch fixes the above issue by adding "raw=True".
test-revlog-raw.py now shows "local test passed", but there is more to fix.
As documented at revlog.__init__, revlog._cache stores raw text.
The current read and write usage of "_cache" in revlog.revision lacks of
raw=True check.
This patch fixes that by adding check about raw, and storing rawtext
explicitly in _cache.
Note: it may slow down cache hit code path when raw=False and flags=0. That
performance issue will be fixed in a later patch.
test-revlog-raw now points us to a new problem.
