Invalidate & regenerate script snapshots for globally installed dart apps #21904
Description
Activity
Added Area-Pub label.
For completeness:
$ which dartformat
/usr/.../kustermann/.pub-cache/bin/dartformat
$ cat $(which dartformat)#!/usr/bin/env sh
This file was created by pub v1.9.0-dev.0.0.
Package: dart_style
Version: 0.1.0-dev
Executable: dartformat
Script: format
dart "/usr/local/google/home/kustermann/.pub-cache/global_packages/dart_style/bin/format.dart.snapshot" "$@"
Removed Priority-Unassigned label.
Added Priority-High label.Try upgrading pub to the latest bleeding edge and running "pub cache repair". This should have been fixed in r42055.
It works, but the fact that it prints
"Wrong script snapshot version, expected 'f6711525cff9f7d0d08595166664b767' found 'a3a313ea90040f8a3aaa5f443ecbb3db'"
is not nice at all.
One way of avoiding this would be to add something like "dart --test-snapshot-compatibility file.snapshot", so one can ask the VM whether it can read the snapshot, instead of just trying to run it and see what happens :-/
If one would implement this, you could also use "exec dart ..." instead.
This issue has been moved to dart-lang/pub#1217.
Reproduction on my machine:
$ pub global activate -sgit https://github.com/dart-lang/dart_style
$ dartformat
Wrong script snapshot version, expected 'f6711525cff9f7d0d08595166664b767' found '74629058babcf012a75ec8e5b364e464'
Pub should make sure to invalidate script snapshots and re-generate them (on demand) when the dart binary changed.
