The way you are currently doing this is going to build 7 lists. Each call to list() will create one (so thats 4) and each addition will create a new intermediate list (and there are 3 of those). that is quite expensive in terms of memory allocation. Ideally we want to use one list and use list.extend:

comment_types = (
    self.comments,
    self.screenshot_comments,
    self.file_attachment_comments,
    self.general_comments,
)
comments = []

for comment_type in comment_types:
    comments.extend(comment_type.filter(timestamp__gt=timestamp))

So there are 4 comment types (comments, general, file attachment, and screenshot). That means for every review we will be doing four queries, so we're going to be doing 4 * r queries. We really don't want to be doing this.

If we had a large review request, with say 100 reviews, someone could query the api with ?timestamp=1970-01-01T00:00:00Z and get every review and we'd have to do 400 database queries. This can lead to denial of service attacks.

We really want to do the minimum number of queries here, which will be four. Instead of going through each individual review, you'll have to query through each comment class, e.g.:

review_pks = [review.pk for review in new_reviews]
new_comments = []

comment_types = (Comment, FileAttachmentComment, GeneralComment, ScreenshotComment)

for comment_cls in comment_types:
    new_comments.extend(comment_cls.objects.filter(
        review_id__in=review_pks, timestamp__gt=timestamp))

If we need to parse out comments to their respective reviews afterwards, we can post-process the dataset.

rswanson Nov. 19, 2016, 12:18 p.m.

That's a really good point that I hadn't considered. Thanks for the suggestion!

Replies are not comment updates. Replies are actually a Review object with base_reply_to having a non-null value.

rswanson Nov. 19, 2016, 12:18 p.m.

Good to know. So far I'm querying for diffsets, reviews, and comments. In my original planning I thought that would be sufficient information to gather for the new update notifications, but now I'm not so sure. Should I be querying for replies as well?

reviewboard/webapi/resources/review_request_last_update.py (Diff revision 5)

Show all issues

We will probably want to get reviews and replies in two separate lists (may want to confer with christian on that). However, you can do one query for each type of review + reply and then filter them out in python land.

rswanson Nov. 19, 2016, 12:18 p.m.

Thanks for the heads up. I've changed the code to include these objects separately for now. I'll be sure to follow up with Christian.

Change Summary:

Addressing review comments. Broke up reviews and replies from being returned in the same list. Started developing unit tests in line with other API classes.

This should be the WebAPI resource and not the model, i.e. [reviewboard.webapi.resources.base_comment.BaseCommentResource] (I think?) You will want to build the docs and see if this one works.

The docs you want to check are the webapi/ docs, not the class documentation for the resource.

After you remove the pytz import you can convert to a  aware time with

In this case we actually want the timezone to stay as UTC.

The overall results of the API look good. There's some additions in this change that don't need to be there, and some consistency things to work on. Good work so far, though!

I don't think we should be adding new methods that just produce different variations of a query here. This query is simple enough that it can and should be used by the caller.
The reason is that we don't want to establish precedent. We probably have a hundred or more distinct queries involving attributes of a ReviewRequest throughout the codebase, and if we had a method for each one in this class, the class would massively balloon up.
So instead, let's get rid of this and just do this query directly where it needs to be called.

This isn't too helpful to the caller. There should be suitable error information.

However, we're also not actually working with form data, so the error is incorrect.

There's really a lot of code in this try/except. What part is expected to raise the ValueError? We should limit the code around that, and perhaps not error out but instead fall back to old behavior (not showing the new fields).

rswanson Nov. 24, 2016, 3:40 p.m.

The datetime conversion of the timestamp is what is expected to raise the ValueError. Your suggestion makes a lot of sense, we can just give the user the same data they're used to if the timestamp isn't correct.

This won't (or shouldn't, anyway) result with the timestamp saved to the review request in the DB. Instead of setting review.timestamp, and calling save() (which is what publish()), you will have to do:

Review.objects.filter(pk=review.pk).update(timestamp=timestamp)

I needed to add this in order to specify a non-current timestamp on a mock review for my unit tests. Would your suggestion still apply in that case?

Don't use exceptions like this for flow control.
Instead:


if not timestamp:

        fields: {

Christian suggested a different alternative in his most recent review, which I chose to follow. His argument was that this isn't the appropraite case for INVALID_FORM_DATA.

reviewboard/webapi/resources/review_request_last_update.py (Diff revision 16)

is the timestamp param passed into this function the curent timestamp or is when the last update was made (which I assumed) and how is it differnt from the server_timestamp?

rswanson Dec. 4, 2016, 2:05 p.m.

The server keeps track of a review request / review / diffset, etc with a timestamp related to when it was created or last updated. The timestamp parameter being passed in here allows the user to see all updates that have occurred SINCE a specified timestamp. Effectively the timestamp could be anything!

You can refactor this to remove code duplication.

These keys are common between all responses, so you can further refactor the code to do:


response_keys = {
    'timestamp': server_timestamp,
    'user': user,
    'summary': summary,
    'type': update_type,
}

# try/except to check for timestamp ...

if timestamp is None:
    # Calculate new_diffsets, etc.
    response_keys.update({
        'diffset_update': new_diffsets,
        'review_updates': new_reviews,
        'reply_updates': new_replies,
        'comment_updates': new_comments,
        'field_updates': field_updates,
    })

return 200, {
        self.item_result_key: response_keys,
    }, {
        'ETag': etag,
    }


This eliminates the multiple returns and makes it easier to follow.

Additionally, can you ensure the keys are listed in alphabetical order when being inserted?
