[Development] State of dev branch in CI

Tue Jan 10 13:45:17 CET 2017

Hi,

As a heads-up to everyone: Tony's changes are in effect now and staging of changes that target the dev branch for modules outside of qtbase should work again.

Hi,

Sounds good to me. I’ll proceed with that.
Funny that the only platform we’ve managed to get in during the last half a year or year is immediately causing problems so that we have to remove it ;)

Hi,

I just had another chat with Liang about this situation. We can't get a newer qtbase into qt5.git because tests in declarative fail, some of it also due to a newer qtbase (and the qurl changes). So the path we would propose is

    (1) The CI team reverts the addition of RHEL 7.2 to the dev branch that brought us here.

    (2) We either get fixes or blacklist-additions into the corresponding modules, WHILE the rest of development of modules in Qt outside qtbase with the dev branch can resume.

    (3) RHEL 7.2 is re-added to the CI when it passes tests.

We need agreement and help from the CI team to do that.

Simon

Hi,

as far as I can tell this is not resolved yet. It appears that the macOS 10.9 replacement with 10.10 happened, but a test failure on RHEL 7.2 showed up.

Hi Simon,

is this resolved yet?

Cheers,
