- fixed directory iteration order
- reduced providervalidation memory usage
- disabled one test case of TestSnapshotSparseRestore
(filed https://github.com/kopia/kopia/issues/3178 to fix)
* Remove remaining internal uses of Readdir
* Remove old helpers and interface functions.
* Update tests for updated fs.Directory interface
* Fix index out of range error in snapshot walker
Record one error if an error occurred and it's not limiting errors
* Use helper functions more; exit loops early
Follow up on reviewer comments and reduce code duplication, use more
targetted functions like Directory.Child, and exit directory iteration
early if possible.
* Remove fs.Entries type and unused functions
Leave some functions dealing with sorting and finding entries in fs
package. This retains tests for those functions while still allowing
mockfs to access them.
* Simplify function return
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.
