Add atomic push - #138
Add atomic push#138
Conversation
Since time elapses between the checkout the github workflow performs and the eventual push this action invokes the remote HEAD may have changed. If this is the case the HEAD update will be rejected but any tag (and their commits) will be pushed. In general I think this operation should be atomic, either we push everything or we push nothing. Force pushes still work the way you would expect (i.e. if we force the HEAD update with --atomic everything is still pushed) This also protects from the situation where someone else has seized your tag name in the meantime but not updated your HEAD.

Hi @sleepypikachu, in general it looks good to me. Do you've tested it? |
|
Yes, it is working well for us. We're using this behaviour from my fork :-) |
|
Hi @sleepypikachu, thanks for the update. I'm currently thinking about the case, if the server side do not support the function, will the complete call fail or only the beforehand executed pull? |
|
Hmmm. This is a github action and github does support this feature. So it's hard to imagine what would cause someone to unset this flag. If you feel strongly I'm happy to implement. Just want to understand the motivation. |
|
I'm thinking of a case for GitHub Enterprise support. I'm not sure if there's a possibility to disable the function inside a GTE system. |
|
Gotcha, no problem. Will implement. |

@sleepypikachu Thanks for the contribution! I'll merge the PR. |
