fixed some issues that prevented go test from passing on Windows:
- webdav client used \ instead of /
- need retries around mmap.Open()
- paths are prefixed with C:\ on windows
- time.Now() does not always move forward on Windows
Those will make it possible to securely host 'kopia server' embedded
in a desktop app that runs in the background and can access UI.
- added support for using and generating TLS certificates
- added /api/v1/shutdown API to remotely trigger server shutdown
- added support for automatically shutting down server if no requests
arrive in certain amount of time
- added support for generating and printing random password to STDERR
TLS supports 3 modes:
1. serve TLS using externally-provided cert/key PEM files
2. generate & write PEM files, then serve TLS using them
3. generate and use emphemeral cert/key (prints SHA256 fingerprint)
- Use it to compare the entry attributes for all entry types.
Allows comparing differences in file attributes among the
contents of two directories. This is useful for verifying
restored contents in end-to-end tests.
- Print message about modified entries only when both entries
are files and they are being compared.
This is enabled by `kopia server --ui` and can be viewed in a browser
at http://localhost:51515/
Right now it can only list snapshots and policies (barely).
`snapshot gc` marks contents not reachable from the root of any snapshot
as soft-deleted
The algorithm is a mark-and-sweep with parallel iteration of objects.
Currently it stores content IDs and object IDs in a map, so won't scale
to huge repositories, but this can be fixed in the future.
This fixes#110 at least for reasonable repository sizes.
Previously, it was possible for Flush() to miss in-flight writes,
but only when using repository manually since Uploader guarantees
there are no in-flight writes when it completes.
With this change Flush() will guarantee that any pending writes
completed before Flush() has started are guaranteed to be committed
to the repository before Flush() returns.
This was actually a regression introduced in #105.
Added regression test to prevent it from reoccurring.
This cleans up the code a lot and removes many ugly hacks.
The performance is pretty reasonable and with separate metadata cache it's likely to stay that way.
Also introduced strongly typed content.ID and manifest.ID (instead of string)
This aligns identifiers across all layers of repository:
blob.ID
content.ID
object.ID
manifest.ID
This updates the terminology everywhere - blocks become blobs and
`storage.Storage` becomes `blob.Storage`.
Also introduced blob.ID which is a specialized string type, that's
different from CABS block ID.
Also renamed CLI subcommands from `kopia storage` to `kopia blob`.
While at it introduced `block.ErrBlockNotFound` and
`object.ErrObjectNotFound` that do not leak from lower layers.
The splitter in question was depending on
github.com/silvasur/buzhash which is not licensed according to FOSSA bot
Switched to new faster implementation of buzhash, which is
unfortunately incompatible and will split the objects in different
places.
This change is be semi-breaking - old repositories can be read, but
when uploading large objects they will be re-uploaded where previously
they would be de-duped.
Also added 'benchmark splitters' subcommand and moved 'block cryptobenchmark'
subcommand to 'benchmark crypto'.
