The goal of this change is to make it possible to do explicit "rc" releases from the daml repo. We've had a good run at the old way of working, where RCs were supposed to be "whatever the latest snapshot is at the time of release", but since we've moved away from time-based releases that attitude has become less and less in line with reality. And if we're deliberately creating RCs now, why not call them that?

This script is meant to help with managing releases. Usage:
|
|
|
|
$0 snapshot SHA PREFIX
|
|
Prints the snapshot line for commit SHA as a release candidate for
|
|
version PREFIX. For example:
|
|
|
|
$ $0 snapshot cc880e2 0.1.2
|
|
cc880e290b2311d0bf05d58c7d75c50784c0131c 0.1.2-snapshot.20200513.4174.0.cc880e29 SPLIT_RELEASE
|
|
|
|
Any non-ambiguous git commit reference can be given as SHA.
|
|
|
|
$0 check
|
|
Checks that each line of the LATEST file is well-formed.
|
|
|
|
Any other invocation will display this help message.
|
|
|
|
