## Changes
This change replaces usage of the `repofiles` package with the `filer`
package to consolidate WSFS code paths.
The `repofiles` package implemented the following behavior. If a file at
`foo/bar.txt` was created and removed, the directory `foo` was kept
around because we do not perform directory tracking. If subsequently, a
file at `foo` was created, it resulted in an `fs.ErrExist` because it is
impossible to overwrite a directory. It would then perform a recursive
delete of the path if this happened and retry the file write.
To make this use case work without resorting to a recursive delete on
conflict, we need to implement directory tracking as part of sync. The
approach in this commit is as follows:
1. Maintain set of directories needed for current set of files. Compare
to previous set of files. This results in mkdir of added directories and
rmdir of removed directories.
2. Creation of new directories should happen prior to writing files.
Otherwise, many file writes may race to create the same parent
directories, resulting in additional API calls. Removal of existing
directories should happen after removing files.
3. Making new directories can be deduped across common prefixes where
only the longest prefix is created recursively.
4. Removing existing directories must happen sequentially, starting with
the longest prefix.
5. Removal of directories is a best effort. It fails only if the
directory is not empty, and if this happens we know something placed a
file or directory manually, outside of sync.
## Tests
* Existing integration tests pass (modified where it used to assert
directories weren't cleaned up)
* New integration test to confirm the inability to remove a directory
doesn't fail the sync run
## Changes
Rename all instances of "bricks" to "databricks".
## Tests
* Confirmed the goreleaser build works, uses the correct new binary
name, and produces the right archives.
* Help output is confirmed to be correct.
* Output of `git grep -w bricks` is minimal with a couple changes
remaining for after the repository rename.
## Changes
This PR changes the files.Delete() mutator to delete the sync snapshots
file on destroy. This ensures that files will be uploaded when the
bundle is uploaded again.
## Tests
- [x] Manual test: Ran `bricks bundle destroy`, observed that the sync
snapshots file was deleted.
The previous approach would proceed to execute all requests prior to
returning the first error. This is solved with `errgroup.WithContext`
that cancels the context if a routine returns an error.
JSON output makes it easy to process synchronization progress
information in downstream tools (e.g. the vscode extension).
This changes introduces a `sync.Event` interface type for progress events as
well as an `sync.EventNotifier` that lets the sync code pass along
progress events to calling code.
Example output in text mode (default, this uses the existing logger calls):
```text
2023/03/03 14:07:17 [INFO] Remote file sync location: /Repos/pieter.noordhuis@databricks.com/...

Before this commit this would error saying that the repo doesn't exist yet.
With this commit it creates the directory, but only after checking that
the repo exists.
This commit changes the code in repository.go to lazily load gitignore
files as opposed to the previous eager approach. This means that the
signature of the `Ignore` function family has changed to return `(bool,
error)`.
This lazy approach fits better when other code is responsible for
recursively walking the file tree, because we never know up front which
gitignore files need to be loaded to compute the ignores. It also means
we no longer have to "prime" the `Repository` instance with a particular
directory we're interested in and rather let calls to `Ignore` load
whatever is needed.
The fileset wrapper under `git/` internally taints all gitignore objects
to force a call to [os.Stat] followed by a reload if they have changed,
before calling into the [fileset.FileSet] functions for recursively
listing files.
This moves `git.FileSet` to `libs/fileset` and decouples it from the Git package.
It is made aware of gitignore rules in parent directories up to the
repository root as well as gitignore files in underlying directories
through the `fileset.Ignorer` interface.
The recursive directory walker is reimplemented with [filepath.WalkDir].
Follow up to #182.
By default the command runs an incremental, one-time sync, similar to the
behavior of rsync. The `--persist-snapshot` flag has been removed and the
command now always saves a synchronization snapshot.
* Add `--full` flag to force full synchronization
* Add `--watch` flag to run continuously and watch the local file system for changes
This builds on #176.
This change also adds testcases for checking if the specified path is
nested under the valid base paths and fixes an edge case where the user
could synchronize into their home directory directly.

The code depended on the project package for:
* git.FileSet in the watchdog
* project.CacheDir to determine snapshot path
These dependencies are now denormalized in the SyncOptions struct.
Follow up for #173.
