labhub.py: add migrate_issue plugin #521

aabhaas-vaish · 2018-04-07T15:56:04Z

Introduce migrate_issue plugin that adds ability
to migrate an issue from a source repo to target
repo, both owned by the org.

Issue title, issue description and all comments
are copied with a few additional details appended to
the the description and comments. Source issue is
referenced in the target issue and is closed after
the migration is complete.

Closes #518

Please make this workable for gitlab repos as well. The whole point of labhub is to provide a unified front for both GitHub and GitLab, and hence the name LabHub 😉

maybe include the author as well? Migrate issue opened by @author from ... so the author the issue follows new issue as well

I was trying the same, but there seems to be some problem with the IGitt module I have installed on my system using pip, as it says author of the issue is not an attribute even though I find this method here: https://gitlab.com/gitmate/open-source/IGitt/blob/master/IGitt/GitHub/GitHubIssue.py and I am not particularly sure why but might be some problem with my system... 😅

this isnt a url .. it is a format string.

it is safer to check that it is open.

If there is only one message, you can use return 'foo' instead of yield & return

it is a bit strange seeing this variable mixed in amoung all the regex matches.

please read every line of your diff and ask yourself if it can be improved.

the regex won't work for gitlab sub groups, see regex for other commands to see how its done

Since this regex is most likely be duplicated in every command, make a new constant with the regex to match github/gitlab url, and then append it to your command. Do this as part of another issue after this is complete 😉

@meetmangukiya , I used the same regex as used in unassign_cmd and it uses the same regex. How should I go about this? 😕

What about we only capture the URL here, without using regex to parse it, and then split it with a helper function that can be re-used in each command which takes a git hoster URL ?

Remove this and make the string multiline, something like

a = ('some long string which doesnt fit in 80 chars' 'Next part of the string. This both will be concantenated into one')

I don't think this is the case for gitlab comments, use IGitt API to get comment link, if it doesn't exist, make upstream contribution

Will be excluding the comment URLs for the current PR and will make another PR when upstream contribution in IGitt is made.

Are you sure the time returned has no UTC offset?

I tested it on it on my own forks and there was no UTC offset included there. However, I wasn't able to find documentation explicitly mentioning anything about offsets 😅
