This small PR makes a few QoL improvements to the release.sh script: 1. The snapshot command will now work for any commit. Previously, it would refuse to print the snapshot suffix for commits that were not ancestors of the `master` branch. The new version will print a warning if the commit does not seem to be part of a release branch, but will still print the result. 2. On checking the LATEST file, the script will now print a slightly more useful error message if the file format is not valid. 3. The snapshot command will now print the entire line to be added into the LATEST file, rather than just the version suffix. CHANGELOG_BEGIN CHANGELOG_END

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
|
|
|
|
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.
