Commit b76e4458b1eb3c32e9824fe6aa51f67d2b251748 made the mirror block
|
|
|
26ba25 |
job respect block-job-cancel's @force flag: With that flag set, it would
|
|
|
26ba25 |
now always really cancel, even post-READY.
|
|
|
26ba25 |
|
|
|
26ba25 |
Unfortunately, it had a side effect: Without that flag set, it would now
|
|
|
26ba25 |
never cancel, not even before READY. Considering that is an
|
|
|
26ba25 |
incompatible change and not noted anywhere in the commit or the
|
|
|
26ba25 |
description of block-job-cancel's @force parameter, this seems
|
|
|
26ba25 |
unintentional and we should revert to the previous behavior, which is to
|
|
|
26ba25 |
immediately cancel the job when block-job-cancel is called before source
|
|
|
26ba25 |
and target are in sync (i.e. before the READY event).
