Description

This is an architectural change for Review Board 2.6 that affects
extensions. Currently, there are some default review request actions
(like "Close -> Submitted" or "Download Diff" or "Ship It!") that have
been hardcoded into the template. Extensions can provide custom actions
by passing dictionaries into a variety of ActionHooks.

This change encapsulates this logic into a BaseReviewRequestAction
class. Instead of passing ActionHook-style dictionaries into the hooks,
extensions can now pass in BaseReviewRequestAction instances. Hardcoded
actions have been ripped out from the template and retrofitted into a
cleaner action registration system. Other new features include:

- Up to two levels of action nesting via BaseReviewRequestMenuActions.
- A should_render() method that subclasses of BaseReviewRequestAction
can override in order to implement complex action rendering behaviour.
- A register_actions() method that can be used to add a custom action to
any of the default menu actions.
- An unregister_actions() method that can be used to remove any of the
default actions.
- A ReviewRequestActionHookModel for providing action callbacks in JS.

Testing Done

- Ran and passed the relevant reviewboard unit tests.
- Manually verified that all default actions display correctly in
  different scenarios.
    1. Test in all three types of pages ("Reviews", "File", "Diff").
    2. Test in normal as well as local sites.
    3. Test DownloadDiffAction with the slider (for interdiffs).
    4. Test as an authenticated user and as a guest.
    5. Test when the review request is pending review and is submitted.
- Added my own extension that provides its own actions in different ways
  and manually verified that each action displayed correctly in
  different scenarios.
    1. Test adding actions and menu actions via action-style dicts.
    2. Test adding actions and menu actions via action instances.
    3. Test adding menu actions that contain their own menu actions.
    4. Test that a menu action can override its children from rendering.
    5. Test unregistering a default action.
    6. Test unregistering a child action of a default menu action.
    7. Test registering a new child action on a default menu action.
- Added unit tests that cover the above functionality, which all pass.
- Added my own JS extension that provides its own callback and manually
  verified that the callback is correctly triggered when its corresponding
  action is clicked.
- Built the Sphinx docs and manually verified that my updates rendered
  correctly.

reviewboard/reviews/actions.py (Diff revision 1)

From what I can tell, the only difference between primary and secondary actions was their positions in the list (where primary were always put after secondary, so they're closer to the right).

adriano Sept. 27, 2015, 9:55 p.m.

Thanks for the clarification. From what you said, it seems that I don't really need to worry about this. Extensions should probably be able to reorder actions as desired, instead of grouping them into primary or secondary.

reviewboard/reviews/actions.py (Diff revision 1)

So I see what you're doing here with these class methods, and it makes sense, but I don't think it's consistent with the way the rest of RB's extension framework works - specifically, the Fields API, which I believe this new Actions API is supposed to expose.

Here are some Fields defined in the MozReview extension, for example: https://hg.mozilla.org/hgcustom/version-control-tools/file/d1e664f1dc8d/pylib/mozreview/mozreview/fields.py

And here are the built-in fields being manipulated: https://hg.mozilla.org/hgcustom/version-control-tools/file/835dbd9444db/pylib/mozreview/mozreview/extension.py#l140

So I suspect what we want to do is expose some functions in actions.py that can be used to manipulate the current actions, and an equivalent to ReviewRequestFieldsHook (but for Actions) that makes it easy (and backwards compatible for ReviewRequestActionsHook... I'll just call it ReviewRequestActionsHook2 for now to differentiate, but that shouldn't be its name) to inject new Actions.

So the final result would be that, as an extension developer, I subclass something like a ReviewRequestBaseAction, and override something like a "should_render" method for saying whether or not the Action should apply under the current conditions.

And then I would instantiate the new ReviewRequestActionsHook2, passing in the subclass, along with the URL name that the hook should apply to.

Does that make sense?

adriano Sept. 27, 2015, 10:15 p.m.

Thanks, that makes a lot of sense. I originally had copied over the same structure used in the fields.py file, but as an experiment I wanted to see what would happen if I "brought everything one level down". Surprisingly, it sort of worked.
I understand that consistency is important (my experiment will be easy enough to revert), but I am a bit curious as to why the code is slightly more complicated than it perhaps needs to be. If we create an EditReviewAction class that subclasses some BaseReviewRequestAction (instead of instantiating an edit_review_action object from a ReviewRequestAction class), then does this mean that we could instantiate multiple objects from a single EditReviewAction class? To me, it seems that there is a one-to-one correspondence between an action class and an action instance (the lack of instance-level attributes confuses me).

These shouldnt be on the class. They should be module-levels. See my other comment about the pages/forms stuff.

reviewboard/reviews/actions.py (Diff revision 1)

The issue has been resolved. Show all issues

Ideally, the should_render function should be a member funciton. This way, the people using this code can override the function (which by default should probably return True) to do complicated stuff with, e.g., the request.

Re: my earlier comment, this would be

adriano Sept. 27, 2015, 10:56 p.m.

Thanks. As I mentioned in a reply to Mike, I originally had copied over the same structure used in the fields.py file, but as an experiment I wanted to see what would happen if I "brought everything one level down". Surprisingly, it sort of worked. At any rate, I'm going to go ahead and revert my experiment.
I am a little bit confused as to when we should ever put things at the instance level (instead of the module or class level). If we make an EditReviewAction class that subclasses some BaseReviewRequestAction (instead of instantiating an edit_review_action object from a ReviewRequestAction class), then does this mean that we could instantiate multiple objects from a single EditReviewAction class? To me, it seems that there is a one-to-one correspondence between an action class and an action instance (the lack of instance-level attributes confuses me).
In particular, should this should_render method actually be a class method (and can it access the full context, since this is needed by the Download Diff action)? Something like:

class EditReviewAction(BaseReviewRequestAction):
    """..."""

    @classmethod
    def should_render(cls, context):
        return context['request'].user.is_authenticated()

You may want to ping Christian about whether or not these should be @classmethods or instance methods.

adriano Sept. 29, 2015, 10:22 p.m.

Thanks, I didn't know that. Many of the docstrings in this actions.py file were taken directly from the fields.py file, which doesn't quite use the imperative mood. Should I update the docstrings in the fields.py file as well to be consistent?

Also, I added a new for_review_request_action method in templatetags/reviewtags.py whose docstring starts with "Loops through all review request actions." Like the fields.py file, the docstrings in templatetags/reviewtags.py also don't use the imperative mood. Should these docstrings be updated as well?

This is shaping up nicely :)
There are quite a few missing docstrings and I didn't flag all instane of this. In general, all classes should have docstrings. All methods (except things that are being overridden, unless they have a special use case) should be documented as well.
As far as formatting goes, classes should be formatted as follows (note the blank line between the docstring and the attribute):

class ClassName(object):
    """Single line summary.

    Multi-line description.
    """

    first_member = 1


Also, things like side effects and important notes should be in the multi-line description of the docstring, not under a separate section. The args/return sections are pulled out by sphinx into build docs, but those other sections won't be.

:py:class:`BaseReviewRequestAction`

reviewboard/reviews/actions.py (Diff revision 5)

This should use reST clode blocks.
E.g.,

For example:

.. code-block:: python
   class UsedOnceAction(BaseReviewRequestAction):
       action_id = 'once'
       label = 'This is used once.'

   class UsedMultipleAction(BaseReviewRequestAction):
       def __init__(self, action_id, label):
           self.action_id = 'repeat_' + action_id
           self.label = label


This really shouldn't be REPL output either

reviewboard/reviews/actions.py (Diff revision 6)

The issue has been resolved. Show all issues

No blank line between the docstring and the first line of code for functions.

adriano Oct. 13, 2015, 12:35 p.m.

I did have it like that originally, but Barret recommended putting a newline there (https://reviews.reviewboard.org/r/7661/#review22277).

david Oct. 13, 2015, 12:37 p.m.

So we have a blank line between the docstring and the first thing in a class, but not a function. The distinction here is that members/methods in a class always have a blank line separating them (and the docstring is a member), but lines of code in a function don't.

Because you're manipulating this in a method, it probably shouldn't be data on the class. Can you create an __init__ and assign this there?

This comment confuses me.

adriano Oct. 13, 2015, 8:52 p.m.

This comment is intended to explain why I am using context.get('has_diffs', True) instead of context['has_diffs']. A review request can be viewed from three different tabs: "Reviews", "File", and "Diff" (the third "File" tab only appears when viewing file attachments). In the "Reviews" and "File" tabs, there is a has_diffs key that can be looked up in the context dictionary. Its corresponding value in the dictionary is set to True iff the review request has at least one diff.

In the "Diff" tab on the other hand, the has_diffs key does not exist in the context dictionary. It makes sense not to include this redundant piece of information; after all, the only way we could have accessed the "Diff" tab in the first place is if the corresponding review request had a diff already.

Perhaps a better comment would be something like:

# If has_diffs does not exist, then we must be in the Diff tab.
# So the corresponding review request must already have a diff.

Hmm. I'm not sure how I feel about passing in a list and having the render() method append to it. How about we let render() return a string, and then we build the result using a list comprehension?

return ''.join([
    action.render(context)
    for action in get_review_request_actions()
])


This way the data flow in render() is entirely one-way.

Change Summary:

Allow extensions to provide their own actions (as dicts or instances).

Removed 3 action hook basic tags:
1. review_request_action_hooks
2. review_request_dropdown_action_hooks
3. diffviewer_action_hooks
Added a BaseReviewRequestActionHook for other hooks to inherit from.
Changed the _top_level_ids from a list to a deque.
- Registering an action involves appending to the left of a deque, so
we sometimes have to iterate through actions in reverse.

Change Summary:

Clean up comments and variable names and some redundant logic.

Renamed actions to children_actions.
Improved docstring explanation for registering actions.
Removed BaseReviewRequestMenuAction's redundant logic in render().

Description:

		Overview

		This is an architectural change for Review Board 2.6 that affects extensions and requires both front-end (JavaScript) and back-end (Python) work.
		Currently, there are some default actions (like "Review" or "Ship It!") that can be performed on review requests. Extensions can provide custom actions by subclassing various `ActionHooks`.
		The goal of this project is to encapsulate this logic into a `ReviewRequestAction`. Instead of using hooks, extensions will be able to provide custom actions by registering them as `ReviewRequestAction` instances (or remove the default actions by unregistering them).



		Part 1: Update the simplest default actions.

		Added the `BaseReviewRequestAction` class (this was based on the `BaseReviewRequestField` class).
		Added the `for_review_request_action` block tag (this was based on the `for_review_request_fieldset` block tag).
		Updated the "Review", "Ship It!", and "Download Diff" actions.
		Added the `hidden` class variable for `DownloadDiffAction`.
		Modified `view_diff.html` so that simple actions work for all tabs.
		Switched from using a `SortedDict` to using a `dict` and a `list`.



		Part 2: Update the default menu actions.

		Refactored how URLs are initialized by calling `local_site_reverse()`.
		Updated the "Close" and "Update" menu actions (and their children).
		Changed from a block tag to a basic tag (`review_request_actions`).
		Made actions responsible for rendering and registering.
		Added a `menu_action.html` file that includes a new `action.html` file.



		Part 3: Allow extensions to provide their own actions.

		Removed 3 action hook basic tags: 1. `review_request_action_hooks` 2. `review_request_dropdown_action_hooks` 3. `diffviewer_action_hooks`
		Added a `BaseReviewRequestActionHook` for other hooks to inherit from.
		Changed the `_top_level_ids` from a `list` to a `deque`.
		Allowed menu actions to have their own children menu actions.
		Added a new `children_actions` basic tag.



		TODO:

		Fix 7 commented out unit tests (they fail either due to missing tags that were deleted, or because ID's must now be unique) and add my own.
		Make sure that extensions can unregister default actions.
		Start looking at the `RB.ReviewRequestEditorView` JavaScript class.
	+
	+
	+
	+	(Low Priority) Questions for the Mentors:
	+
	+	Should `BaseReviewRequestActionHook` be included in `__all__`?
	+	Should IDs for `BaseReviewRequestActions` be optional, similar to action-style dicts?
	+	Should `BaseReviewRequestActions` also accept images as fields?
	+	Should we update the other `ActionHooks` (for the header) as well?
	+	Should we call them `DropdownActions` or `MenuActions`?
	+	How should nested menus be displayed?

Testing Done:

		Ran and passed the relevant reviewboard unit tests.
~		Manually verified that all default actions display correctly in different scenarios.
~		Added my own extension that provides its own actions in different ways and manually verified that each action displayed correctly in different scenarios.
	~	Manually verified that all default actions display correctly in different scenarios. Test in all three tabs ("Reviews", "File", "Diff"). Test in normal as well as local sites. Test `DownloadDiffAction` with the slider (for interdiffs). Test as an authenticated user and as a guest. Test when the review request is pending review and is submitted.
	~	Added my own extension that provides its own actions in different ways and manually verified that each action displayed correctly in different scenarios. Test adding actions and menu actions via action-style dicts. Test adding actions and menu actions via action instances. Test adding menu actions that contain their own menu actions. Test that a menu action can override its children from rendering.

I'm not sure why all of these are class methods. Can you clarify for me?

adriano Oct. 20, 2015, 3:10 p.m.

I was switching a lot between different types of methods actually. At first, they were static methods because they never used instance attributes like actions. Then I changed them to class methods because for example _register_and_get() calls _to_action_instance(), and subclasses might want to override these methods with their own implementations.
I suppose that we could extend this argument and say that extensions might want different instances of the same subclass to override these methods in different ways. For example:

class Foo(BaseReviewRequestActionHook):
    def __init__(self, extension, actions=[], is_awesome=True, *args, **kwargs):
        super(Foo, self).__init__(extension, actions, *args, **kwargs)
        self.is_awesome = is_awesome

    def action_should_render(self, context):
        if not self.is_awesome:
            return False
        return super(Foo, self).action_should_render(self, context)


So in the interest of being as flexible as possible, I guess I should just change them all to be simple instance methods. (Also, I forgot to put an underscore before action_should_render() - it should be a "protected" method as well.)

david Oct. 20, 2015, 3:12 p.m.

Instance methods sound good to me. In Python, static methods are used only occasionally and class methods are used almost never.

Can we just pull these out into top-level classes? There's no real reason to hide them inside their parent menus, and it makes it harder to read.

"children_actions" is kind of redundant. How about either "children" or "child_actions"?

This is probably not a terribly reliable way to detect this. It might be a lot better to pass the review request into should_render.

adriano Oct. 23, 2015, 12:08 a.m.

I'm not sure what you mean by this. Basically, the should_render(self, context) method gets called from only one place: render(self, context, action_key, template_name). If I change the function prototype to something like should_render(self, context, review_request), then how would I get the review request in the first place? The only way I know how to retrieve the current review request is by grabbing it from the context, so I would naively do something like:
def render(self, context, action_key, template_name):
    content = ''

    if self.should_render(context, context['review_request']):
        context.push()
        context[action_key] = self
        content = render_to_string(template_name, context)
        context.pop()

    return content

Is there a special call that I can make to retrieve the current review request from somewhere other than the context?

Alternatively, perhaps you mean that it's fine to retrieve the review request from the context, but I shouldn't rely on using the has_diffs key. Instead, perhaps I should manually retrieve this from the review request by doing something like:
def should_render(self, context):
    review_request = context['review_request']
    request = context['request']
    draft = review_request.get_draft(request.user)
    diffsets = review_request.get_diffsets()

    if (draft and draft.diffset_id) or len(diffsets) > 0:
        self.label = _('Update Diff')
    else:
        self.label = _('Upload Diff')

    return context['upload_diff_form']


(I'm not terribly sure how I can check for an upload_diff_form without using the context.)

We should maybe also pass the request into this, and introspect the url/view name, instead of trying to reverse engineer it from the context contents.

Change Summary:

Fix the commented out unit tests and implement unregistration.

Both basic tags now have try/except blocks.
Both base actions now have an unregister method (good for unit tests).


Use AppliesToURLMixin and add one unit test.

BaseReviewRequestActionHook now also subclasses AppliesToURLMixin.
_action_should_render was removed.


Address the issues raised by David.

Replaced class methods with instance methods.
Modified some public methods to be protected instead.
Used resolver_match instead of relying on riskier context keys.
Renamed children actions -> child_actions.

_() doesn't work this way. The l10n scanner looks at the source code and extracts all string literals which are wrapped with gettext. If you call this on a variable, the scanner won't pull it out.

If actions want to localize, they should call ugettext_lazy (aka _()) on their labels themselves (which it looks like you're already doing).

Added a public register_actions() method.
Added detailed comments as to how I might refactor the code.


Address the issues raised by David.

Stopped surrounding variables with _().
Wrapped _should_render's return statements with bool().
Replaced literals with imported constants (sort of like an enum).
Cleaned up some variable names and how default arguments are handled.
Cleaned up various whitespace and wrapping conventions.
Child actions can now be passed in via the constructor.


Allow extensions to unregister actions.

Added a public unregister_actions() method.

Description:

		Overview

		This is an architectural change for Review Board 2.6 that affects extensions and requires both front-end (JavaScript) and back-end (Python) work.
		Currently, there are some default actions (like "Review" or "Ship It!") that can be performed on review requests. Extensions can provide custom actions by subclassing various `ActionHooks`.
		The goal of this project is to encapsulate this logic into a `ReviewRequestAction`. Instead of passing action-style dictionaries into the hooks, extensions will be able to provide custom actions by registering them as `ReviewRequestAction` instances. Furthermore, we will be able to remove any subset of the default actions by simply unregistering them.



		Part 1: Update the simplest default actions.

		Added the `BaseReviewRequestAction` class (this was based on the `BaseReviewRequestField` class).
		Added the `for_review_request_action` block tag (this was based on the `for_review_request_fieldset` block tag).
		Updated the "Review", "Ship It!", and "Download Diff" actions.
		Added the `hidden` class variable for `DownloadDiffAction`.
		Modified `view_diff.html` so that simple actions work for all tabs.
		Switched from using a `SortedDict` to using a `dict` and a `list`.



		Part 2: Update the default menu actions.

		Refactored how URLs are initialized by calling `local_site_reverse()`.
		Updated the "Close" and "Update" menu actions (and their children).
		Changed from a block tag to a basic tag (`review_request_actions`).
		Made actions responsible for rendering and registering.
		Added a `menu_action.html` file that includes a new `action.html` file.



		Part 3: Allow extensions to provide their own actions.

		Removed 3 action hook basic tags: 1. `review_request_action_hooks` 2. `review_request_dropdown_action_hooks` 3. `diffviewer_action_hooks`
		Added a `BaseReviewRequestActionHook` for other hooks to inherit from.
		Changed the `_top_level_ids` from a `list` to a `deque`.
		Allowed menu actions to have their own children menu actions.
		Added a new `child_actions` basic tag.
		Both basic tags now have try/except blocks.
		Both base actions now have an unregister method (good for unit tests).
		`BaseReviewRequestActionHook` now also subclasses `AppliesToURLMixin`.



	+	Part 4: Allow extensions to register/unregister actions by ID.
	+
	+	Added a public `unregister_actions()` method.
	+	Replaced `is_top_level` with `parent`.
	+	Added `_parent` so that extensions can unregister by ID.
	+	Added a public `register_actions()` method.
	+
	+
	+
		TODO:

		Add more unit tests.
~		Make sure that extensions can unregister default actions.
	~	Keep thinking about how to refactor the code (see the TODO comment).
		Start looking at the `RB.ReviewRequestEditorView` JavaScript class.



		(Low Priority) Questions for the Mentors:

~		Should `BaseReviewRequestActionHook` be included in `__all__`?
	~	How can I refactor my code (see the TODO comment)?
		How should nested menus be displayed?

Testing Done:

		Ran and passed the relevant reviewboard unit tests.
		Manually verified that all default actions display correctly in different scenarios. Test in all three tabs ("Reviews", "File", "Diff"). Test in normal as well as local sites. Test `DownloadDiffAction` with the slider (for interdiffs). Test as an authenticated user and as a guest. Test when the review request is pending review and is submitted.
~		Added my own extension that provides its own actions in different ways and manually verified that each action displayed correctly in different scenarios. Test adding actions and menu actions via action-style dicts. Test adding actions and menu actions via action instances. Test adding menu actions that contain their own menu actions. Test that a menu action can override its children from rendering.

The issue has been dropped. Show all issues

It doesn't really matter, but I think it would be nicer to have this set after we register all the default actions.

adriano Nov. 7, 2015, 8:43 a.m.

Hmm. I tried changing the order, but this results in infinite recursion since default_action.register() will call _populate_defaults() and enter the if statement forever. I suppose that we could instead use some kind of enum called _status that keeps track of three different states: UNPOPULATED, IS_POPULATING and POPULATED. Then we could have something like:
def _populate_defaults():
    """Populate the default action instances."""
    global _status

    if _status != POPULATED:
        from reviewboard.reviews.default_actions import default_actions

        _status = IS_POPULATING

        for default_action in reversed(default_actions):
            default_action.register()

        _status = POPULATED


Was this what you had in mind?

Instead of just casting to bool, I think we should explicitly test review_request.repository is not None.

This can be rewritten using logging.exception, which we're slowly transitioning to:

```
Same here.
```

Change Summary:

Added a reset_actions() method (useful in shutdown() for extensions).

Replaced the default_actions variable with a get_default_actions()

  factory method so that _populate_defaults() can grab a fresh copy of

  the original default actions after a reset.


Refactored when child actions get registered.

Child actions now get registered as soon as they are passed in to the

  parent menu action's constructor. So when the parent gets registered,

  it no longer has to recursively register its children.


Added a unit test for modifying the default actions and cleaned up code.

Reverted a change from the previous commit, since it led to infinite

  recursion.
Fixed docstring omission.
Replaced 'P' with constant.

So registered_actions is a temporary that is only used in this function, but we're creating a iterator out of it (via reversed()) and then turning it into a new list. This is rather inefficient.
Instead, can we do:

registered_actions.reverse()
return registered_actions


This way, registered_actions will be reversed in-place and so we won't waste time and memory creating a new list and freeing the old one.

Change Summary:

Address the issues raised by Barret and improve the ActionHook class.

Improved various wording/whitespace/bracket/docstring issues.
Changed Version 2.6 to Version 2.7.
Used ~.parent_dir. to help Sphinx find the correct hyperlinks.
Made ActionHook and other hooks more consistent with the docs/updates.
Extracted/improved the DictAction and DictMenuAction helper classes.
Made wording more consistent for ActionHook-style and

ReviewRequestDropdownActionHook-style dictionaries.

Description:

~		Overview
	~	This is an architectural change for Review Board 2.7 that affects
	+	extensions. Currently, there are some default review request actions
	+	(like "Close -> Submitted" or "Download Diff" or "Ship It!") that have
	+	been hardcoded into the template. Extensions can provide custom actions
	+	by passing dictionaries into a variety of ActionHooks.

~		This is an architectural change for Review Board 2.6 that affects extensions and requires both front-end (JavaScript) and back-end (Python) work.
~		Currently, there are some default actions (like "Review" or "Ship It!") that can be performed on review requests. Extensions can provide custom actions by subclassing various `ActionHooks`.
~		The goal of this project is to encapsulate this logic into a `ReviewRequestAction`. Instead of passing action-style dictionaries into the hooks, extensions will be able to provide custom actions by registering them as `ReviewRequestAction` instances. Furthermore, we will be able to remove any subset of the default actions by simply unregistering them.
	~	This change encapsulates this logic into a BaseReviewRequestAction
	~	class. Instead of passing ActionHook-style dictionaries into the hooks,
	~	extensions can now pass in BaseReviewRequestAction instances. Hardcoded
	+	actions have been ripped out from the template and retrofitted into a
	+	cleaner action registration system. Other new features include:

~
~
~		Part 1: Update the simplest default actions.
~
~		Added the `BaseReviewRequestAction` class (this was based on the `BaseReviewRequestField` class).
~		Added the `for_review_request_action` block tag (this was based on the `for_review_request_fieldset` block tag).
	~	Arbitrarily nested actions via BaseReviewRequestMenuActions.
	~	A _should_render() method that subclasses of BaseReviewRequestAction can override in order to implement complex action rendering behaviour.
	~	A register_actions() method that can be used to add a custom action to any of the default menu actions.
	~	An unregister_actions() method that can be used to remove any of the default actions.
	~	A reset_actions() method that extensions can call on shutdown.
	~	A ReviewRequestActionHookModel for providing action callbacks in JS.
-		Updated the "Review", "Ship It!", and "Download Diff" actions.
-		Added the `hidden` class variable for `DownloadDiffAction`.
-		Modified `view_diff.html` so that simple actions work for all tabs.
-		Switched from using a `SortedDict` to using a `dict` and a `list`.
-
-
-
-		Part 2: Update the default menu actions.
-
-		Refactored how URLs are initialized by calling `local_site_reverse()`.
-		Added the `BaseReviewRequestMenuAction` subclass.
-		Updated the "Close" and "Update" menu actions (and their children).
-		Changed from a block tag to a basic tag (`review_request_actions`).
-		Made actions responsible for rendering and registering.
-		Added a `menu_action.html` file that includes a new `action.html` file.
-
-
-
-		Part 3: Allow extensions to provide their own actions.
-
-		Removed 3 action hook basic tags: 1. `review_request_action_hooks` 2. `review_request_dropdown_action_hooks` 3. `diffviewer_action_hooks`
-		Added a `BaseReviewRequestActionHook` for other hooks to inherit from.
-		Changed the `_top_level_ids` from a `list` to a `deque`.
-		Allowed menu actions to have their own children menu actions.
-		Added a new `child_actions` basic tag.
-		Both basic tags now have try/except blocks.
-		Both base actions now have an unregister method (good for unit tests).
-		`BaseReviewRequestActionHook` now also subclasses `AppliesToURLMixin`.
-
-
-
-		Part 4: Allow extensions to register/unregister actions by ID.
-
-		Added a public `unregister_actions()` method.
-		Replaced `is_top_level` with `parent`.
-		Added `_parent` so that extensions can unregister by ID.
-		Added a public `register_actions()` method.
-		Changed child action registration to happen as soon as they are passed in to the parent menu action's constructor.
-		Added a `reset_actions()` method (useful in `shutdown()` for extensions) and changed `default_actions` to a factory method.
-		Added a `ReviewRequestActionHook` model for providing callbacks.
-		Updated the documentation for action hooks.
-
-
-
-		TODO:
-
-		Fix the issues that the mentors will inevitably find. =]
-
-
-
-		(Low Priority) Questions for the Mentors:
-
-		How should nested menus be displayed?

Testing Done:

		Ran and passed the relevant reviewboard unit tests.
~		Manually verified that all default actions display correctly in different scenarios. Test in all three tabs ("Reviews", "File", "Diff"). Test in normal as well as local sites. Test `DownloadDiffAction` with the slider (for interdiffs). Test as an authenticated user and as a guest. Test when the review request is pending review and is submitted.

		Added my own extension that provides its own actions in different ways and manually verified that each action displayed correctly in different scenarios. Test adding actions and menu actions via action-style dicts. Test adding actions and menu actions via action instances. Test adding menu actions that contain their own menu actions. Test that a menu action can override its children from rendering. Test unregistering a default action. Test unregistering a child action of a default menu action. Test registering a new child action on a default menu action.
		Added my own JS extension that provides its own callback and manually verified that the callback is correctly triggered when its corresponding action is clicked.
		Built the Sphinx docs and manually verified that my updates rendered correctly.

This is fantastic. Now, my review is large, because I'm in nit-picky mode, and want to get everything super-polished.

There are a couple of larger discussion points, which I cover below. Basically, the actions are setting state at runtime on themselves, but the actions are instances shared across every user rendering the page. This will lead to bad state at times, and so must be redesigned a little.

I also want to see more unit tests covering all the base action behavior, for registering/unregistering/iterating through actions (and handling all the success/error states), and unit tests for each default action covering the possible states. This will ensure things don't accidentally break down the road.

I'd rather not use a table for this (and require the shorthand for the actions). A bullet point list is sufficient.

Same below.

What's this for?

Ideally, all named lists of URLs should be defined in exactly one place, reviewboard.urls, so depending on what this is, maybe it should live there.

adriano Nov. 21, 2015, 10:59 a.m.

It's passed in to the apply_to attribute of ReviewRequestActionHook, so that it only renders on the review request page (and not the file attachment or diff viewer pages). I'll go ahead and move it there.

I'd prefer not to align like this. Instead:

* ``id``:
  The ID of the action (optional).


* ``label``:
  ...

(Make sure that renders correctly, though.. there are other docs that do something similar to this, so they can be used as a base.)

This is assuming some things about the data passed in, and if the keys are missing, the caller's going to get a less-than-nice exception. Ideally, this function should verify that action_dict has all the keys needed, and raise a KeyError with a friendly message if one is missing.

This is kind of named awkwardly. From the name, I have no real sense of what it's doing, and the description doesn't really cover it any further.

Looking through the code, I believe it's taking the list passed in and creating a new list of normalized values. So, maybe _normalize_actions, with a description saying what it's taking in and what it's turning them into.

Since newly registered top-level actions are appended to the left of the other previously registered top-level actions, we must iterate through the actions in reverse. However, we don't want to mutate the original actions and we want to return the same (possibly normalized) actions in their original order. Hence, we reverse twice in this method.

I'll add the above explanation to the docstring. (Of course...it's possible that appending to the left of the _top_level_ids deque might be a bad design in the first place, and that we should perhaps be storing the top level action IDs in reverse instead. Do you have any thoughts?)

Let's flesh this out a bit, mention that this means it'll only show up on the review request page containing reviews. I don't know that we want to mention "tabs" so much, as we're really dealing with pages, and who's to say whether tabs are the UI of choice for the product in all forms down the road.

This is one of the older unit test suites in the codebase. Let's go ahead and move all action unit tests into a new class. This makes it easier for us to run the test suite only for action hook functionality.

These are nice cleanups, but really should be broken out into its own change, to help keep this change slimmer.
Generally speaking, cleanup changes should be standalone. When running a git blame in the future, and seeing a change to this line, I'll wonder how it relates to the action hook work. If instead the change says it's standardizing names for something, then great!
That said, I don't know that this is cleanup that needs to happen (I'd rather see it done piece-meal as this mega-class is broken up into smaller test suite classes), so my preference would be to undo it.

Let's flesh this out just a bit, describing the resulting state.

May also need a warning that this will impact any extensions that have registered actions. (In fact, the extension hooks should probably become more bullet-proof, catching unregistration errors and logging them, instead of blowing up.)

So I have a concern here, and I want to follow up on how this works.
We're registering instances, right? So if this is doing self.label = ... anywhere, it can pollute other renders (as the same codebase is going to be serving up multiple people). That's going to be a real problem.
Basically, if we're registering instances, rather than having an instance tied to that page load, then we cannot ever set anything on the class at runtime. We instead need functions that return the values needed.
In that case, we'd want get_label(), get_url(), etc. that take a context and return a value, much like should_render().

Various docstrings have been added/improved.
The :py:class: prefix was added to each dict.
The _should_render method is now public.
When using '(list of X)', the type X is now singular.
Added the use of :guilabel:.
Swapped the order of apply_to and actions in __init__.
Renamed _to_action_instance to _convert_action.
Unit tests now call reset_actions().
Reverted the extraneous code cleanup in tests.py.
Removed documentation of private variables.


TODO:

Address the remaining issues raised by Christian.
Redesign how actions set their state at runtime.
Add more unit tests.

Change Summary:

Add the remaining ActionTests, DefaultActionTests, and ActionHookTests.

Added unit tests that cover registering/unregistering actions.
Added unit tests that cover success/error states.
Added unit tests that cover get_url (in view-diff, etc).


Add default action unit tests that cover should_render().

Rearranged the order of default actions to make more sense.
Added the ActionTests and DefaultActionTests classes.


Redesign actions so that their state is only set once on initialization.

	~	A clear_all_actions() method that extensions can call on shutdown.
		A ReviewRequestActionHookModel for providing action callbacks in JS.

Testing Done:

		Ran and passed the relevant reviewboard unit tests.
~		Manually verified that all default actions display correctly in different scenarios. Test in all three tabs ("Reviews", "File", "Diff"). Test in normal as well as local sites. Test DownloadDiffAction with the slider (for interdiffs). Test as an authenticated user and as a guest. Test when the review request is pending review and is submitted.
	~	Manually verified that all default actions display correctly in different scenarios. Test in all three types of pages ("Reviews", "File", "Diff"). Test in normal as well as local sites. Test DownloadDiffAction with the slider (for interdiffs). Test as an authenticated user and as a guest. Test when the review request is pending review and is submitted.
		Added my own extension that provides its own actions in different ways and manually verified that each action displayed correctly in different scenarios. Test adding actions and menu actions via action-style dicts. Test adding actions and menu actions via action instances. Test adding menu actions that contain their own menu actions. Test that a menu action can override its children from rendering. Test unregistering a default action. Test unregistering a child action of a default menu action. Test registering a new child action on a default menu action.
~		Added my own JS extension that provides its own callback and manually verified that the callback is correctly triggered when its corresponding action is clicked.
~		Built the Sphinx docs and manually verified that my updates rendered correctly.
	~	Added unit tests that cover the above functionality, which all pass.
	~	Added my own JS extension that provides its own callback and manually verified that the callback is correctly triggered when its corresponding action is clicked.

Change Summary:

Address the issues raised by Christian.

Reverted version number from 2.7 back to 2.6.
Implemented a nesting limit of 2.
Improved the wording of various comments (in particular, 'depth' has

  been replaced with 'height').
Added a height property that gets lazily computed on registration.
Updated previous unit tests to cover more possibilities.
Added four new unit tests that cover the new height logic.

Description:

~		This is an architectural change for Review Board 2.7 that affects
	~	This is an architectural change for Review Board 2.6 that affects
		extensions. Currently, there are some default review request actions
		(like "Close -> Submitted" or "Download Diff" or "Ship It!") that have
		been hardcoded into the template. Extensions can provide custom actions
		by passing dictionaries into a variety of ActionHooks.

		This change encapsulates this logic into a BaseReviewRequestAction
		class. Instead of passing ActionHook-style dictionaries into the hooks,
		extensions can now pass in BaseReviewRequestAction instances. Hardcoded
		actions have been ripped out from the template and retrofitted into a
		cleaner action registration system. Other new features include:

~		Arbitrarily nested actions via BaseReviewRequestMenuActions.
~		A should_render() method that subclasses of BaseReviewRequestAction can override in order to implement complex action rendering behaviour.
~		A register_actions() method that can be used to add a custom action to any of the default menu actions.
~		An unregister_actions() method that can be used to remove any of the default actions.
~		A clear_all_actions() method that extensions can call on shutdown.
~		A ReviewRequestActionHookModel for providing action callbacks in JS.
	~	- Up to 2 levels of action nesting via BaseReviewRequestMenuActions.
	~	- A should_render() method that subclasses of BaseReviewRequestAction
	~	can override in order to implement complex action rendering behaviour.
	~	- A register_actions() method that can be used to add a custom action to
	~	any of the default menu actions.
	~	- An unregister_actions() method that can be used to remove any of the
	+	default actions.
	+	- A clear_all_actions() method that extensions can call on shutdown.

Factored out some duplicate setup logic in ActionTests.
Cleaned up various whitespace and comments.

Seriously good work in here. I'm really looking forward to landing this. Sorry it took me so long to get back to you with another review, and thanks for jumping on board to get the other change in :)
I have a handful of comments. Most of them are stylistic, and repeating prior comments but helping to point out other locations for the same thing. Nothing too big in here.
If you don't have time to make the changes, please do let me know. We can work to get it in as well.

Not sure that we should document registering without a hook in an extension, since that means more that the extension has to manage when shutting down.

This is probably not something we want to explicitly document here. Instead, we should somehow save and restore the actions we unregistered.

The reason is that if you have two extensions, each registering actions, and you shut down one that calls clear_all_actions, it will affect the other.

adriano Feb. 11, 2016, 10:21 a.m.

I found this from here: http://www.sphinx-doc.org/en/stable/rest.html#lists-and-quote-like-blocks

Basically, reST supports autonumbered lists and so will replace each of the #. symbols with 1., 2., 3., and so on. This way, if we later want to insert or delete some of the items in the numbered list, we won't have to manually renumber them from scratch.

Can return reversed(registered_actions) instead.

adriano Feb. 10, 2016, 12:05 a.m.

I did originally have it like that. However, Barret (https://reviews.reviewboard.org/r/7661/#comment27059) argued that this technique is more efficient. This is because reversing the list in-place reuses the old list's memory, whereas reversed(registered_actions) would require more memory since it creates a copy of the old list and frees the old memory.

Not sure RuntimeError is right here. Is this something that should never happen, or something that the user can trigger? If the former, an assert is more appropriate. If the latter, we should have an exception class for this, probably, or maybe a ValueError.

adriano Feb. 11, 2016, 10:29 a.m.

This is indeed something that the user can trigger if, say, the depth limit is 2, and an extension tried to add a menu action as follows:

BaseReviewRequestActionHook(self, actions=[
   DepthZeroMenuAction([
       DepthOneFirstItemAction(),
       DepthOneMenuAction([
           DepthTwoMenuAction([  # This depth is acceptable.
               DepthThreeTooDeepAction(),  # This action is too deep.
           ]),
       ]),
       DepthOneLastItemAction(),
   ]),
])


I'll go ahead and make a custom DepthLimitExceededError class that inherits from ValueError.

This comment isn't about this line per se, but we have this nifty new Registry thing that Barret put together that makes it easier to manage all this sort of registration state.

As mentioned earlier in the review, this is kind of dangerous for extensions, because they can stomp all over each other, and we don't want to encourage that.

What we probably want is a way to retrieve and re-apply a registration.

That's probably additional work at this point. Maybe we should nuke this for now, and brainstorm a solution separately for another change (whether we work on it or you -- you don't have to commit to anything :)

The issue has been resolved. Show all issues

Instead of a list (since this is "only" one thing), maybe call this main_review_request_url_name?

Change Summary:

Address Christian's remaining issues.

Simplified the documentation example (don't use clear_all_actions()).
Explicitly overrode should_render() instead of using a lambda.
Clarified that clear_all_actions() should only be used by unit tests.
Added a forgotten :py:class:.
Renamed depth -> max_depth and improved its documentation.
Improved the docstring of register_actions().
Switched from using "you" to using "we".
Cleaned up various comments.


Address the rest of the easier of the issues raised by Christian.

Changed only_review_request_url_names to be a single string.
Replaced context (dict) -> context (django.template.Context).
Reformatted string interpolation so that % starts the next line.
Removed extraneous parentheses when wrapping strings.
Documented all apply_to args as optional.
Replaced newly deprecated @basictag with @simple_tag.
Replaced RuntimeError with a custom DepthLimitExceededError.
Wrapped context.pop() in a finally block, and added a unit test to

  cover this.
Added a TODO (should use djblets.registries).
Factored out clear_all_actions() into tearDown().
Added a Model Attributes section.
Fixed various whitespace, formatting, and typos.


Address the easier of the issues raised by Christian.

Removed the bullets from dict key descriptions.
Merged (optional) with variable types.
Converted bold words to monospace.
Moved the "Raises" section to be in front of the "Returns" section.
Corrected the type of *args to be tuple.
Changed (function) to (callable).
Removed periods from unit test docstrings.
Added class names to unit test docstrings.

Improved various comments.

Description:

		This is an architectural change for Review Board 2.6 that affects
		extensions. Currently, there are some default review request actions
		(like "Close -> Submitted" or "Download Diff" or "Ship It!") that have
		been hardcoded into the template. Extensions can provide custom actions
		by passing dictionaries into a variety of ActionHooks.

		This change encapsulates this logic into a BaseReviewRequestAction
		class. Instead of passing ActionHook-style dictionaries into the hooks,
		extensions can now pass in BaseReviewRequestAction instances. Hardcoded
		actions have been ripped out from the template and retrofitted into a
		cleaner action registration system. Other new features include:

~		- Up to 2 levels of action nesting via BaseReviewRequestMenuActions.
	~	- Up to two levels of action nesting via BaseReviewRequestMenuActions.
		- A should_render() method that subclasses of BaseReviewRequestAction
		can override in order to implement complex action rendering behaviour.
		- A register_actions() method that can be used to add a custom action to
		any of the default menu actions.
		- An unregister_actions() method that can be used to remove any of the
		default actions.
-		- A clear_all_actions() method that extensions can call on shutdown.
		- A ReviewRequestActionHookModel for providing action callbacks in JS.
