registry/config.go

You'll want to update the error text

Thanks @ncdc for the catch !
I have updated the code.

thaJeztah · 2015-03-03T07:37:31Z

Note to reviewers; it looks like the limit in registry v2 has not yet been updated, see #10392 (comment)

ncdc · 2015-03-05T15:05:13Z

registry/config.go

The v2 registry currently has a minimum of 2, not 4: https://github.com/docker/distribution/blob/master/registry/api/v2/names.go#L16

ncdc · 2015-03-05T15:05:42Z

The current max in the v2 registry is 255, not 256: https://github.com/docker/distribution/blob/master/registry/api/v2/names.go#L32

This PR for the v2 registry removes the 30-character component limit distribution/distribution#242

@dmp42 @dmcgowan

Please review

dmp42 · 2015-03-06T21:25:15Z

@shishir-a412ed can you update the comparison to 255?
Thanks.

dmcgowan · 2015-03-07T01:52:18Z

Ping @ncdc can you drive forward getting this updated to match the rules in distribution

ncdc · 2015-03-07T01:57:51Z

Yes, I chatted with Shishir today about updating it to match. I'll follow
up on Monday. Thanks.

Updated ticket title to reflect the correct limit.

stevvooe · 2015-03-13T21:10:52Z

registry/registry_test.go

Could replace this with a testcase that triggers the short case?

stevvooe · 2015-03-13T21:11:09Z

LGTM with testcase for short namespace.

dmcgowan · 2015-03-13T21:14:13Z

Commit message hasn't been changed to reflect 255 instead of 256 characters

shishir-a412ed · 2015-03-13T22:18:12Z

@dmcgowan Updated the commit message to reflect 255.

shishir-a412ed · 2015-03-14T16:10:17Z

@stevvooe I have added 2 testcases, one for short, and one for long namespaces.

@icecrime what are the next steps here?

vbatts · 2015-03-17T14:19:49Z

i've just issued a rebuild to windows, but the linux tests are looking fine.

icecrime · 2015-03-17T16:38:26Z

Windows CI is green after rebuild: pushing to 3-docs-review.

ncdc · 2015-03-17T16:40:04Z

@icecrime thanks. FYI I grepped through the Docker codebase and the only references I could find (quickly) to a 30 character maximum were the docker io API and the hub registry spec docs, both of which talk about hub/registry usernames needing to be no more than 30.

icecrime · 2015-03-17T16:40:58Z

Good, I was running the same search on my side and can't see any reference to these limits in docs/ either :-) Thanks!
