* server: reworked authn/authz
Previously authentication was done as an wrapper handler and
authorization was inlined. This change moves authn/authz handlers
inside the server and implements separate authorization module that's
individually tested.
Also fixed an issue where server users were not able to see global
or host-level policies.
* PR feedback
* linter: upgraded to 1.33, disabled some linters
* lint: fixed 'errorlint' errors
This ensures that all error comparisons use errors.Is() or errors.As().
We will be wrapping more errors going forward so it's important that
error checks are not strict everywhere.
Verified that there are no exceptions for errorlint linter which
guarantees that.
* lint: fixed or suppressed wrapcheck errors
* lint: nolintlint and misc cleanups

* 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
* 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
Support for remote content repository where all contents and
manifests are fetched over HTTP(S) instead of locally
manipulating blob storage
* server: implement content and manifest access APIs
* apiclient: moved Kopia API client to separate package
* content: exposed content.ValidatePrefix()
* manifest: added JSON serialization attributes to EntryMetadata
* repo: changed repo.Open() to return Repository instead of *DirectRepository
* repo: added apiServerRepository
* cli: added 'kopia repository connect server'
This sets up repository connection via the API server instead of
directly-manipulated storage.
* server: add support for specifying a list of usernames/password via --htpasswd-file
* tests: added API server repository E2E test
* server: only return manifests (policies and snapshots) belonging to authenticated user
* server: when serving HTML UI, prefix the title with string from KOPIA_UI_TITLE_PREFIX envar
* kopia-ui: support for multiple repositories + portability
This is a major rewrite of the app/ codebase which changes
how configuration for repositories is maintained and how it flows
through the component hierarchy.
Portable mode is enabled by creating 'repositories' subdirectory before
launching the app.
on macOS:
<parent>/KopiaUI.app
<parent>/repositories/
On Windows, option #1 - nested directory
<parent>\KopiaUI.exe
<parent>\repositories\
On Windows, option #2 - parallel directory
<parent>\some-dir\KopiaUI.exe
<parent>\repositories\
In portable mode, repositories will have 'cache' and 'logs' nested
in it.
This is mostly mechanical and changes how loggers are instantiated.
Logger is now associated with a context, passed around all methods,
(most methods had ctx, but had to add it in a few missing places).
By default Kopia does not produce any logs, but it can be overridden,
either locally for a nested context, by calling
ctx = logging.WithLogger(ctx, newLoggerFunc)
To override logs globally, call logging.SetDefaultLogger(newLoggerFunc)
This refactoring allowed removing dependency from Kopia repo
and go-logging library (the CLI still uses it, though).
It is now also possible to have all test methods emit logs using
t.Logf() so that they show up in failure reports, which should make
debugging of test failures suck less.
Percentage based on last-known snapshot size
* server: exposed last completed snapshot size in the API
* cli: added support for progress indicator (percentage based on last-known snapshot size)
* htmlui: added progress indicator in the UI (percentage based on last-known snapshot size)
CreateSnapshotSource API for ensuring source exists
Upload - starts upload on a given source or matching sources
Cancel - cancels upload on a given source or matching sources
/api/v1/repo/create
/api/v1/repo/connect
/api/v1/repo/disconnect
Refactored server code and fixed a number of outstanding robustness
issues. Tweaked the API responses a bit to make more sense when consumed
by the UI.
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)
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
