* object: refactored writer to detect split points before writing
This introduces new primitive that will be moved into splitters
themselves in subsequent commits. I'm doing this in small steps to
ensure we don't regress at any time.
* splitter: refactored TestSplitters test
This is use slow (byte-by-byte) and fast (nextSplitPoint) methods of
determining split points.
Note nextSplitPoint is not implemented by splitters yet, but this
verifies that the test is expecting the right thing.
* object: splitter refactoring - replaced ShouldSplit() with NextSplitPoint() everywhere, still not optimized
* splitter: added additional dimension to splitter_test
We split either in large chunks or one byte at a time to catch
the corner cases in the splitter implementation.
* splitter: optimized splitters using NextSplitPoint primitive
This improves splitter performance by about 40% (buzhash) and makes
it virtually free for FIXED splitter.
* goreleaser: added signatures to RPM binaries
Currently goreleaser does not support it, so we're overriding
signing script and signing all RPMs that it produces.
Also changed goreleaser parameters to only publish binaries
when running on linux/amd64.
* build: added automatic publishing of RPMs to a YUM repository
Also fixed RPM file names to match local conventions.
* cli: added --tls-print-server-cert flag
This prints complete server certificate that is base64 and PEM-encoded.
It is needed for Electron to securely connect to the server outside of
the browser, since there's no way to trust certificate by fingerprint.
* server: added repo/exists API
* server: added ClientOptions to create and connect API
* server: exposed current-user API
* server: API to change description of a repository
* htmlui: refactored connect/create flow
This cleaned up the code a lot and made UX more obvious.
* kopia-ui: simplified repository management UX
Removed repository configuration window which was confusing due to
the notion of 'server'.
Now KopiaUI will automatically launch 'kopia server --ui' for each
config found in the kopia config directory and shut it down every
time repository is disconnected.
See https://youtu.be/P4Ll_LR4UVM for a quick demo.
Fixes#583
* repo: refactored client-specific options (hostname,username,description,readonly) into new struct that is JSON-compatible with current config
* cli: added 'repository set-client' to configure parameters of connected repository
* cli: cleaned up 'repository status' output
* cli: simplified mount command
See https://youtu.be/1Nt_HIl-NWQ
It will always use WebDAV on Windows and FUSE on Unix. Removed
confusing options.
New usage:
$ kopia mount [--browse]
Mounts all snapshots in a temporary filesystem directory
(both Unix and Windows).
$ kopia mount <object> [--browse]
Mounts given object in a temporary filesystem directory
(both Unix and Windows).
$ kopia mount <object> z: [--browse]
Mounts given object as a given drive letter in Windows (using
temporary WebDAV mount).
$ kopia mount <object> * [--browse]
Mounts given object as a random drive letter in Windows.
$ kopia mount <object> /mount/path [--browse]
Mounts given object in given path in Unix.
<object> can be the ID of a directory 'k<hash>' or 'all'
Optional --browse automatically opens OS-native file browser.
* htmlui: added UI for mounting directories
See https://youtu.be/T-9SshVa1d8 for a quick demo.
Also replaced some UI text with icons.
* lint: windows-specific fix
The problem was that while dropping deleted entries from the index
we were looking at index-local and nor merged result.
Say index1 has content1 created at t0.
Say index2 has content1 deleted at t1 > t0.
And we're compacting and dropping index entries deleted before t2,
such that t2 > t1.
Because create and delete records are in separate index files, the
compacted file would preserve "created t0" which is wrong.
This fix changes index compaction to always look at resolved content
status.

Fixes#564
cli: added 'kopia policy set --ignore-cache-dirs' option to control
whether to ignore caches (global default=true)
ui: added checkbox to control 'Ignore Cache Dirs' in policy editor
ignorefs: moved ignoring cache directories to ignorefs layer

Globally replaced all use of time with internal 'clock' package
which provides indirection to time.Now()
Added support for faking clock in Kopia via KOPIA_FAKE_CLOCK_ENDPOINT
logfile: squelch annoying log message
testenv: added faketimeserver which serves time over HTTP
testing: added endurance test which tests kopia over long time scale
This creates kopia repository and simulates usage of Kopia over multiple
months (using accelerated fake time) to trigger effects that are only
visible after long time passage (maintenance, compactions, expirations).
The test is not used part of any test suite yet but will run in
post-submit mode only, preferably 24/7.
testing: refactored internal/clock to only support injection when
'testing' build tag is present
* cli: added 'index inspect' which can dump contents of index blob or local file
* repo: added read-only option when connecting to a repo which prevents any mutations

Followup on recent PR #529, some suggestions and discussion after it was merged:
- Express probability as float in range [0,1]
- Add a unit test for DeleteContentsAtDepth
- Add a comment on writeFilesAtDepth explaining depth vs branchDepth
- Refactor pickRandSubdirPath for easier readability and understanding
Upon some reflection, I decided to refactor pickRandSubdirPath() to gather indexes and pick randomly from them instead of the previous reservoir sampling approach. I think this is easier to understand going forward without extra explanation, doesn't have much additional memory overhead, and reduces the number of rand calls to 1.
This will launch 'rclone webdav server' passing random TLS
certificate and username/password and serve predefined rclone
remote path.
This is very experimental, use with caution.
Fixes#313.
Additional / required changes:
* blob: (experimental) support for rclone provider
* server: refactored TLS utilities to separate package
* webdav: add support for specifying trusted TLS certificate fingerprint
* kopia-ui: added rclone support
* kopia-ui: added ability to connect to kopia server
* kopia-ui: update status page to show some data for repositories connected to API server
* kopia-ui: hide user@host selection dropdown for kopia server repositories
* [Robustness] Add additional fio workloads
Add more fio workloads to write files at different depths in random
branches of the generated file system tree.
- Write files at depth
- Write files at a specified depth, creating a new directory branch at
a random depth
- Delete a random directory at a given depth
- Delete some or all of the contents of a random directory at
a specified depth
* [Robustness] Fix for kopia runner and custom work dir
Apply fix similar to #293 for the robustness kopia runner.
Add control for runner working directory.
Fix fswalker to ignore hostname to allow reporting
on walks done across different hosts. Also prevent
Before and After walk data from printing to reduce log size.
