Vitaliy Filippov 4a2dcf7b6b Update the license to VNPL 1.1
VNPL 1.1 is slightly reworded to make it clear that proprietary software
interacting with Vitastor and providing some kind of service to end users isn't
a "Proxy Program" if it's not specially designed to be used with Vitastor.

For example, Windows OS running in a virtual machine stored in a Vitastor
cluster clearly isn't.

Vitaliy Filippov 2d9f09dcb6 Attempt forced trim when stopping an overrun flusher
Fixes a rare hang happening in the event of journal space running out without
new work to do for flushers except the current sector.
The hang could be reproduced more or less consistently with very slow drives.

Vitaliy Filippov 78fbaacf1f External jerasure's w into defines

Vitaliy Filippov 1018764c91 Fix write->delete->write bugs, add & fix some debugging output 2020-12-04 23:21:58 +03:00
Vitaliy Filippov a45e0e5e67 Use custom decoding instead of just jerasure_matrix_decode()
- Cache the decoding matrix
- Don't do unnecessary erasures->erased conversion during decoding
- Avoid extra memory allocations during decoding
- Don't always reconstruct coding chunks
- Reconstruct chunks one-by-one, without overlapping ranges

Vitaliy Filippov 44656fbf67 Allow writes with low version numbers after a delete 2020-12-04 11:54:41 +03:00
Vitaliy Filippov 089f138e0c Allow situations where the journal contains a big_write(v1) after delete(v2) and v1 < v2
Fixes a crash in the following scenario:
- client issues a delete request (object version is at least 2)
- OSD has time to flush it to the metadata, but doesn't have time to move the journal start pointer on disk
- client overwrites the same object and it gets the version number 1 again
- OSD is restarted and sees delete(v=2), big_write(v=1) in the journal
- dirty_db sequence gets broken and OSD crashes with assert("Writes and deletes shouldn't happen at the same time")
