Vitaliy Filippov 989d73f874 Release 1.7.0 
Omnidirectional release

New features:

- Support handling TCP I/O in simple separate io_uring-based [I/O threads](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/config/client.en.md#client_iothread_count) - may increase linear performance to 7-8 GB/s
- Experimental internal etcd replacement - [antietcd](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/config/monitor.en.md#use_antietcd)
- Monitor now has a [built-in Prometheus exporter](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/config/monitor.en.md#enable_prometheus)
- Added a reference [Grafana dashboard](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/mon/scripts/Vitastor-Grafana-6+.json)
- Implement vitastor-cli [osd-tree](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/cli.en.md#osd-tree) and [ls-osd](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/cli.en.md#ls-osd) commands
- Implement vitastor-cli [modify-osd](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/cli.en.md#modify-osd) command
- Implement vitastor-cli [pg-list](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/cli.en.md#pg-list) command
- Implement [VitastorFS defragmentation](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/usage/nfs.en.md#defrag)
- Implement basic node.js binding (not published on npm yet)

Changes:

- Make immediate_commit=all the default everywhere to match default vitastor-disk behaviour
- Make pool-create error message more obvious and add details to it
- Set default etcd_ws_keepalive_interval to 5 seconds (speedup client etcd failover)
- Support OpenStack 2023.2 in Nova and Cinder drivers/patches
- Add patches for libvirt 10.x
- Add patches for QEMU 8.2 and 9.0
- Implement internal restart / run_forever in monitor
- Some source tree refactoring - sources are now moved into subdirectories, monitor is now split into multiple files
- Add vitastor_c_inode_get_immediate_commit in vitastor_c client library
- Make vitastor_kv.h header public

Bug fixes:

- Fix total statistics usec/count/bytes not being reported when delta (bps/iops/lat) is zero
- Prevent infinite loop in NFS on files with incorrect metadata pointing to an empty volume
- Fix READDIR offsets (cookies) in VitastorFS sometimes leading to client infinite loops when reading a directory
- Fix a rare infinite loop during OSD journal flushing (OSD hanging and eating 100 % CPU)
- Fix several bugs which could lead to lost writes in setups without immediate_commit:
  - Client library treated writes as completed before actually completing them, thus missing them in a subsequent fsync
  - Client library didn't repeat writes on the new PG primary when it changed
  - OSDs didn't drop peer connections with dirty writes when stopping PG
- Fix Block Pseudo-FS initialization leading to ENOENTs some time after start
- Fix vitastor-cli merge-based commands (merge/flatten/rm snapshot) slowing down and finally failing when using CAS optimistic locks
- Fix pool create/modify --block_size validation
- Fix TTL comparison for determining failed lease/keepalive requests in OSD
- Add support for size suffixes in pool-create --block_size and --immediate_commit values

Vitaliy Filippov abbba6ade4 Support handling TCP I/O in simple separate io_uring-based I/O threads 
Required mainly for clients, allows to scale parallel client I/O with TCP
from 100-150k iops to ~400k iops and from 2-3 GB/s to at least 7-8 GB/s
with 4 I/O threads, at the same time increasing Q=1 latency by 2x thread
switching delay, which is ~10 us when CPU powersaving is disabled and may
be as high as 200 us when it's enabled.

Vitaliy Filippov ca63cd507d Fix possible infinite loop in flusher (surprisingly reproduced in test_write.sh with iothreads) 2024-06-27 00:38:01 +03:00
Vitaliy Filippov ea0d72289c Treat copied buffers as written only after completing the write in client 
SYNC operation fsyncs only completed operations, so treating writes as "eligible
for fsync" before actually completing them is incorrect

It affected SCHEME=ec test_heal.sh (with immediate_commit=none) test - it was
flapping with lost writes - some non-fsynced writes were legitimately lost by
the OSD, but weren't repeated by the client
