[couchdb] branch prototype/fdb-layer-fix-update-seq-for-local-docs
updated (17b0bc9 -> 0b62f85)
This is an automated email from the ASF dual-hosted git repository.
vatamane pushed a change to branch prototype/fdb-layer-fix-update-seq-for-local-docs
in repository https://gitbox.apache.org/repos/asf/couchdb.git.
discard 17b0bc9 Handle update_seq for _local_docs
new 0b62f85 Handle update_seq for _local_docs
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (17b0bc9)
\
N -- N -- N refs/heads/prototype/fdb-layer-fix-update-seq-for-local-docs (0b62f85)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.

[couchdb] 01/01: Handle update_seq for _local_docs

Handle update_seq for _local_docs
On master `_local_docs&update_seq=true` returns the update sequence of the
database. Even though it might not make much sense since updating local docs
doesn't bump the sequence, it's probably a good idea to stay consistent.
It's also worth mentioning another inconsistency is when FDB returns a
`total_rows` count for `_local_docs` while master returns `null`. I think
that's probably acceptable. Master would return the count if had it available
easily and having it seems like a useful thing and an improvement.
