no-error-log.txt

this is how to reproduce:

1. In managed mode, create a Toaster project choosing the master release
2. Add the meta-raspberrypi layer to the project
3. Set the machine to raspberrypi2
4. Delete the meta-raspberrypi layer from the project
5. Start a build

The build will fail before starting because nothing provides the machine. The error message will not show in the build dashboard.

By the way, builds that fail at the build request stage should have a different build dashboard (see attached document Design - Displaying failed build requests).

I can open a separate issue for this one (Elliot: let me know if you want me to do that)

I have managed to reproduced the toaster exception issue (shown in the attached exception-instead-of-error.png) on master:e35c404537db0b46047fcb2ee7d3645e3e0935c5

This is how:

1. Create a Toaster project selecting the master release
2. Add the layers e100-bsp and e300-bsp. In my database, those 2 layers have different git urls. For the e100-bsp, the git url is 

git://github.com/EttusResearch/meta-ettus.git

For the e300-bsp, the git url is 

https://github.com/EttusResearch/meta-ettus.git

I know the maintainer of those layers has corrected the issue in the layer index, so if your layers data no longer shows the different git urls, you will need to change the database to make it so.

3. Set the ettus-e300 as the project machine
4. Build gps-config

This build throws this error in the toaster_server.log

========================================

And in Toaster shows the following as an exception:

command: bash -c "source /home/yocto/master/_toaster_clones/_git___git.yoctoproject.org_poky_master/oe-init-build-env /home/yocto/master/build 2>&1 >toaster_server.log && bitbake --read /home/yocto/master/build/conf/toaster-pre.conf --postread /home/yocto/master/build/conf/toaster.conf --server-only -t xmlrpc -B 0.0.0.0:0 2>&1 >>toaster_server.log " 

=========================================

I hope this works.

Thanks Belen, the test cases you supplied should both work correctly with this branch (elliot/toaster/error_display-8320).

Patches submitted to toaster mailing list for review:
https://lists.yoctoproject.org/pipermail/toaster/2015-October/003147.html

Now in bitbake master.
