core.loader: Allow vcs loaders to deal with not_found status
ClosedPublic

Authored by ardumont on Mon, Feb 8, 5:02 PM.

Details

Summary

This will allow git, mercurial or svn loader implementations to mark the visit status as
not_found when such event occurs (e.g failing to to remotely communicate with the remote
server, archive not found, etc...).

Technically, this opens a means to trap a NotFound exception from the main loop. Which
finalize the visit and mark its status as "not_found".

Depends on D5035

I think you should return {"status": "failed"} after that line. or maybe I am missing something here ?

swh/loader/core/tests/test_loader.py
227–230

You can remove that if you return the failed status after catching the NotFound exception.

swh/loader/core/loader.py
337–369

These two exception code blocks are quite similar, you could merge them into one and test on the exception type to modify status and log message.

swh/loader/core/loader.py
337–369

it crossed my mind.

I did not act on it as i'm always wondering whether that's within the scope of that diff or with another one about refactoring ¯\_(ツ)_/¯

351

I'm not totally sure about this. That status is about the task and not the visit.
Currently, it's rendering status "uneventful" which is also true.

The thing is, i think with status "failed", the scheduler will schedule it back and
decrement the retries_left counter?

swh/loader/core/loader.py
337–369

I think yo can do it in that diff, you just have to modify the original Exception block and change statuses if the exception type is NotFound,

351

Ah right, I got mistaken by the test that overrides load_status.

swh/loader/core/tests/test_loader.py
227–230

Yes, i mislead myself here ¯\_(ツ)_/¯
(and thus you as well... sorry)

It should have been uneventful to be consistent with the actual runtime behavior.

Adapt according to review:

  • Fix misleading test
  • Merge the try: catch (Exception, NotFound) instructions.

Thanks!

Is the load_status override really needed here ? This should already return the uneventful status if I am not wrong.

unsure, i think i added because otherwise, it'd be "eventful" (default implem ¯\_(ツ)_/¯).
I'll check ;)

    package: Mark visit as not_found when relevant
    
    If any errors happen during the communication with the origin to retrieve package
    information, the visit fails and its status is marked as not_found.
    
    Only pypi, npm and nixguix package loaders are impacted. The other loaders do not read
    anything from their url so there is no way to trigger such possibility.
    
    Note that the nixguix loader got refactored to avoid the side-effect of reading data out
    of the url within the constructor. It was necessary so the check fails and the visit
    status is dealt with as described. Also, this unifies it with how pypi and npm loaders
    deals with the url communication.
