GTMScriptRunner: run:standardError: deadlocks with full error pipe #25

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When GTMScriptRunner is used to call a script which generates a lot of output 
in stderr, the 
run:standardError: method deadlocks because the [fromTask readDataToEndOfFile] 
waits for the 
script to terminate and the script waits for the runner to collect from the 
full stderr pipe.

not yet fixed, but I'm adding a unittest that can be used to work on this and 
that will help make sure we don't 
regress once it's fixed.

Just a note that this issue causes an annoying bug in the CoverStory app:

I believe I've got a fix for this. The solution is to keep both pipes (stdout 
and stderr) empty. To do that we needed a non-blocking way to check for 
available data. I've attached a patch that does this.

The solution in comment #3 by dlreese worked for me.
Project member please fix this and release new version of CoverStory ASAP.
