projectile-grep stalls when project has multiple roots #1482
Description
Expected behavior
A project containing multiple directories specified in the .projectile file as in
+/foo
+/bar
+/baz
Hangs projectile-grep asking for user input to either, kill the current grep and replace the *grep* buffer or continue to hang. Either only the first directory is searched or only the last results are kept, not all results are visible at the same time. This behaviour is specific to grep as it uses the same grep buffer.
Actual behavior
Search all directories included in the project for results and make the results visible at the same time.
Steps to reproduce the problem
- Create a project with multiple subdirectories
- Add the subdirectories to the
.projectilefile as described above - Run
projectile-grepin the project in a way that produces results
