Hi Qt Developers,

We are preparing for Coin production update to baseline version 1.2.0 
which will contain a major change that will force all builds to compile 
their test binaries during build phase by default - unless they are 
static builds because those test binaries would be too large to be saved.

This will require clearing up the entire old storage and with its old 
artifacts, which means that there might be some delay due to dropping 
the Coin storage cache. As a benefit, however, this the feature allows 
us to save the compiled test binaries in storage and uploads them to a 
VM during test phase resulting in time savings for repeated/flaky test 
runs that would always re-compile test binaries. Now they will be reused.

The production update is scheduled for tomorrow (Eastern European Summer 
Time) starting at

  Thu Oct 17 12:00-

Since we have no standard way of building and running tests for qt 
products, we were forced to hack around the modules that were copying 
symlinks, requiring setting linker paths and other quirky stuff. There 
might be some minor breakages to single module builds or qt5 but most of 
them should be covered by now.

Best of luck,
Aapo Keskimölö - Coin maintainer
