pub run
should not emit any output not from the executable
#2545
Comments
This is also breaking our ability to use the protobuf compiler; see https://travis-ci.com/github/sass/dart-sass-embedded/jobs/363118689. In general, I would expect an executable runner to never add its own output to stdout (or stderr), since those streams may be used by the underlying executable to communicate along a particular protocol. |
Even with "only print if there is a console attached" scenario, if any callers relies on stdout it will break. In travis for example, My all dart setup (that dart file was writing a .rc file and printing the tmp filename to source) was: before_script:
- source $(dart pub run xxxx) I had to add a warmup calls just to workaround this issue before_script:
# Dummy initial call
- dart pub run xxxx --help
- source $(dart pub run xxxx) As I change sdk often, just calling
and sometimes
Why not printing to stderr instead? |

Our tests are failing when run against the current dev version of the Dart SDK because

Expected behavior
pub run <executable>
should only emit output from the executable itself.Actual behavior
pub run <executable>
first emitsPrecompiling executable...
