lgtm (minus the build failure that is ;)

(i did not read the test yet though)

one question about some more modules to remove inline.

swh/lister/bitbucket/lister.py
14

Do we entirely drop the old bitbucket lister code?

If yes, you can also remove that module.

Not covered: authentication, max retries, small corner cases (see below)

What do you mean?


What is self.backoff? You're using it both as a time (time.sleep(self.backoff)) and as a dimensionless unit (self.backoff = self.BACKOFF_FACTOR)


And self.request_count should be a local variable of get_pages named retries_count, because it's actually used for. Plus, the way it's currently written, it looks like that whenever it reaches MAX_RETRIES, it will never be reset without creating a new BitbucketLister object.

swh/lister/bitbucket/lister.py
87

maybe a warning if there is more than one set of credentials?

90–101

Shouldn't these be (class)methods of BitbucketListerState?

103
108
113

And why does it need to be Optional[bool] instead of just bool?

174

IMO this yield should be moved before if next_page_url is not None for two reasons:

  1. we probably want to yield body["values"] even if we fail to parse next_page_url
  2. this means we can make last_repo_cdate non-optional and replace last_repo_cdate = None with a break (and make the loop a while True)
175
swh/lister/bitbucket/tests/test_lister.py
164

isn't this a method?

This revision now requires changes to proceed.Thu, Jan 14, 12:34 PM

Sorry, I clicked "submit" too early.

I meant to say I don't have a good idea of how well it fits architecturaly, but I have some small comments nonetheless

What is self.backoff? You're using it both as a time (time.sleep(self.backoff)) and as a dimensionless unit (self.backoff = self.BACKOFF_FACTOR)

Nevermind that, I guess self.backoff = self.BACKOFF_FACTOR is implicitly meant as multiplying the backoff by 1 second. The initial backoff could be configurable though, but that's not very important.

Thanks for the remarks, will go through them.

swh/lister/bitbucket/lister.py
90–101

the new lister API has them as instance methods of the lister, but indeed the API could be amended to have it as ListerState class methods.
I would say, let discuss it and do that later.

swh/lister/bitbucket/tests/test_lister.py
164

oops, will fix this.

swh/lister/bitbucket/lister.py
90–101

yeah that makes sense, let's leave it like this then

  • fix assert
  • fix typing
  • add a warning on credentials

Remove the persistent isort conftest modification from diff

swh/lister/bitbucket/lister.py
105

Can you rename the function to set_credentials, shorter is better. Also parameters should be typed to Optional[str].

111

you can remove that parameter as it is already the default value of the decorator
