## Changes
Also see #525.
The direct download flag has been removed in newer versions because of
the content type issue.
Instead, we can make the command decode the base64 output when the
output mode is text.
```
$ databricks workspace export /some/path/script.sh
#!/bin/bash
echo "this is a script"
```
## Tests
New integration test.
## Tests
New integration test for the read/write parts of the other filers. The
integration test cannot be shared just yet because the Files API doesn't
include support for creating/listing/removing directories yet.
## Changes
Some of the command such as `databricks alerts create` require
positional arguments which are not primitive.
Since these arguments are required, we should correctly set ExactArgs
for such commands
Fixes#367
## Tests
Running `databricks alerts create`

## Changes
"io/ioutil" has been deprecated since Go 1.16: As of Go 1.16, the same
functionality is now provided by package io or package os, and those
implementations should be preferred in new code. See the specific
function documentation for details.
## Tests

## Changes
This is necessary to avoid test interference.

## Changes
Local file reads on Windows require the file handle to be closed after
using it. This commit includes an interface change to return an
`io.ReadCloser` from `Read` to accommodate this.
## Tests
The existing integration tests for the filer interface all pass.
## 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
This PR:
1. Adds the export-dir command
2. Changes filer.Read to return an error if a user tries to read a
directory
3. Adds returning internal file structures from filer.Stat().Sys()
## Tests
Integration tests and manually
## Changes
This captures the recursive deletion of a directory tree in the filer interface.
Prompted by #433.
## Tests
Integration tests pass (ran the filer ones on AWS and Azure).
## Changes
Some of the commands do not support prompts, for example `workspace
get-status` but we were wrongly suggesting customers some option.
Quick fix for this is not to provide prompts for these known commands.
Note: it uses a method from this PR in Go SDK
https://github.com/databricks/databricks-sdk-go/pull/416
## Tests
Running `workspace get-status`
Before
```
andrew.nester@HFW9Y94129 multiples-tasks % ../../cli/cli workspace get-status
Error: Path () doesn't start with '/'
```
After
```
andrew.nester@HFW9Y94129 multiples-tasks % ../../cli/cli workspace get-status
Error: accepts 1 arg(s), received 0
```
## Changes
This change implements:
* Channels for line-by-line output from stdout/stderr
* A function to wait for a sync step to complete (using above)
* Ensure all tests are prefixed `TestAccSync`
* Use temporary paths in WSFS instead of cloning a repo
## Tests
The same integration tests now pass in ~90 seconds (was ~250s).
## Changes
Use cmdio in the version command such that it accepts the `--output` flag.
This removes the existing `--detail` flag which previously made the
command print JSON output.
## Tests
New integration test passes.
## Changes
The pattern `errors.Is(err, fs.ErrNotExist)` is common to check for an
error type.
Errors can implement `Is(error) bool` with a custom equivalence checker.
## Tests
New asserts all pass in the integration test.
Adds a DBFS implementation of the `filer.Filer` interface.
The integration tests are reused between the workspace filesystem and
DBFS implementations to ensure identical behavior.
## Changes
Do not prompt for List methods
## Tests
Running
```
cli workspace list
```
Before
```
cli workspace list
Error: Path () doesn't start with '/'
```
After
```
cli workspace list
Error: accepts 1 arg(s), received 0
```
## Changes
With this PR, all of the command below print version and exit:
```
$ databricks -v
Databricks CLI v0.100.1-dev+4d3fa76
$ databricks --version
Databricks CLI v0.100.1-dev+4d3fa76
$ databricks version
Databricks CLI v0.100.1-dev+4d3fa76
```
## Tests
Added integration test for each flag or command.
