This is the MVP for a driver for RGW that operates on top of a POSIX
filesystem. It supports get, put, list, copy, multipart, external
access via the filesystem itself, and ordered bucket listings via an
LRU-based cache.
Note that this is currently a Filter, indended to run on top of dbstore.
This is because it currently doesn't have any User implementation, so it
depends on dbstore's User. Everything else is implemented in
POSIXDriver. Once there is a User implementation, this will become a
Store, instead of a Filter.
Commit messages from bucket listing cache:
rgw/posixdriver: recycle lmdb database handles as required
While LMDB workflows often do not close/return database handles,
ours continually reuses them. This requires us to close each
handle (atomically) when a cache entry is recycled.
rgw/posixdriver: don't instantiate bucket cache entries from notify events
rgw/posixdriver: incorporate lmdb-safe for now
The current inclusion is based on https://github.com/Martchus/lmdb-safe,
which is actively maintained but currently has some packaging issues the
author has agreed to accept fixes for.
For now, skip the submodule to save time and remove an external dependency.
rgw/posixdriver: fix listing of cached, empty bucket
* check lmdb enumeration result in all cases and w/better style
* add unit test for enumeration of an empty cached directory
rgw/posixdriver: nest lmdbs in a directory under the dbroot path to avoid cleanup issues
rgw/posixdriver: refactor for posix integration
* Derive BucketCache types as templates on a SAL driver and SAL
bucket pair.
* Integrate cache fills as callbacks into SAL layer (or mock, for
tests)
* Renaming and cleanups
rgw/posixdriver: add bucket cache implementation and tests
Adds free-standing cache of buckets and object names, with
bucket names (and listing attributes, upcoming) managed in
a hashed set of lmdb databases, which provides ordering and
a high-performance listing cache.
An framework for notification on new object creation (e.g.,
outside S3 workflow) is provided, and a Linux implementation
using inotify.
