Add comparer interface which gathers data on a path and
compares that data to a new path, returning error if the path
differs in any way from the input data. The details of what
constitutes a difference is left to the implementation.
FSWalker implementation uses Walk and Report to do the data
gathering and comparison. Filters are applied to sort out any
differences that might be expected (e.g. ctime, atime, mtime,
rename of root directory after restore).
Fixes print for error handling policy. Previously was printing
pointer address, now dereference pointer to print boolean itself.
Nil check in case the caller passes a policy with nil. In that
case print "false" which is the behavior in uploader for nil
pointer.
* Ignore read errors based on policy settings
Added an error handling policy section. Can independently control error handling for directory and file read errors, toggle-able from the `policy set` command to either "true", "false", or "inherit". If any read error is hit, the error handling will check the effective policy on whether to ignore it or not. Currently there is no differentiation between read error types, though in the future we may want to add the `errors.Is(err, os.ErrPermission)` conditional.
Fix was implemented such that the policy ignores read errors ONLY on child entries of the source. So a snapshot will still fail if the source root directory itself can't be read, but you can ignore the error if a file or a subdirectory in the snapshot source root can't be read. I did this to address some otherwise strange behavior where you would successfully snapshot (because you ignored the error), but couldn't restore that snapshot because nothing really happened during the operation.
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
Temporary workaround for compile issues on MacOS and Windows due
to upstream fswalker bug. Only build the reporter and walker
packages as GOOS=linux for now.
Adds a wrapper around `Walk` that takes a Policy (protobuf definition) and performs a walk using it as configuration. The resulting Walk struct pointer is returned. The only exported functionality is unfortunately to read the Policy as a protobuf text file, so the implementation creates a temporary policy file whose lifetime is the duration of the call.
Adds a wrapper around the the FSWalker reporter `Compare` functionality. Takes a config file and two Walk pointers and compares the walks, returning the pb-defined Report struct. Again, the only exported functionality for reading config information is to read it as a protobuf text file. Creates a temporary config file, whose lifetime is the duration of the call, to pass in to the fswalker function.
This automatically launches Kopia CLI with new flags:
`--tls-generate-cert` which generates in-memory TLS certs for the server
and prints its fingerprint to stderr.
`--random-password` which sets up random base auth password
KopiaUI will then listen to the stderr messages and parse the cert
fingerprint and password and automatically provide them in the browser
it opens to show the UI.
This ensures that any local process (or script in a browser, etc.)
other than KopiaUI itself won't have access to the server API nor
UI because they won't know the ephemeral random password and won't
be able to intercept it due to TLS protection.
There's now one target, `travis-release` that can be run
locally, or on Travis CI except for:
- code signing (Travis on non-PR runs)
- publishing artifacts to GH releases (Travis on tagged releases)
- creating long-term repository for testing (Travis on tagged releases)
