Analysis Server runs 'pub list-package-dirs' too many times (malformed pubspecs)

[alexander-doroshko]

(SDK 1.13-dev.7.0)

• Checkout project https://github.com/MikeMitterer/dart-material-design-lite. It contains 62 pubspec.yaml files of which 54 are valid and 8 are invalid (they are templates with placeholders).
• Open this project in the IDE. Analysis Server reports that it runs 'pub list-package-dirs' 62 times which is fine. Server warm up takes just 47 seconds (I guess no 3rd party packages analysis because no pub get done).
• Now run 'pub get' for all valid pubspecs (recommended to do it from the IDE)
• Close and reopen IDE

At this moment server says that 'pub list-package-dirs' was already started more than 2000 times and it already took 15 minutes. I'm killing the process as I can't wait more.

Note that if I delete malformed pubspecs from the project and restart the IDE it helps a bit. Analysis Server runs pub list 150 times in this case (still more than 54 - amount of pubspecs left) and server warms up in 4 minutes.

Do we have a Milestone for this?
