For the sake of consistency with out own service commands and for kubectl,
`kn plugin list` should print:
```
No plugins found.
```
`kn service list` should print:
```
No services found.
```
and not `No resources found.` like it does now.
Same for `kn routes list`.
* Update serving to 0.8. Try building.
* Find the right serving version
* Change our own import path to knative.dev to match
* Remove dependency on old version of client
* Update yaml template
* Add sleep to test to deal with race
* fix merge conflict
* Update vendor modules
* refactor(plugins): Improved and simplified verifier and plugin list
* Added proper executable check for current user
* Refactor plugin_list to make it more straightforward
* Seperate errors and warnings
* Don't return an error when no plugin is installed and `plugin list` is called
* Simplified tests
* Check assumption that a prefix is given in verify()
* fix(plugins): Fixed broken homedir expansion
* fix(plugin): Adapted to proper permission handling
E.g. if u-x, g+x and the user has the group of the file, but is also owner of the file then he is not allowed to execute the file.
* test(plugins): Added checks for the execution check for plugins
* chore(plugins): optimized tests to reflect the real unix behaviour
* chore(plugins): Moved plugin seenMap to top-level verify method.
Also, allow symlinks without warnings.
* refactor(plugins): Split up some methods in plugin_verifier to make them shorter
* fix: Tuned `plugin list` for better handling when no plugin directory exists
This version contains the following:
1. wraps the main root Kn command to support plugin
2. plugins are any executable in kn's config new pluginDir
variable which defaults to $PATH
3. plugins must have name kn-*
4. 'kn plugin list' sub-command to list found kn plugins
5. skips any kn plugins found with name that match core
commands, e.g., kn-service would be ignored
6. can execute any valid kn plugins found, e.g.,
`kn valid` where the plugin file `kn-valid` is in path
specified in 2.
7. unit tests (using gotest.tools)
And is missing:
1. integration tests
2. plugin install command
3. plugin repository command
4. plugin / Knative server version negotiation
5. anything else we agree on in plugin req doc
I plan to create issues for the things missing so we don't
end up with an even bigger PR. It's already big as is but is a
good MVP as per plugins requirement doc.
