Overview
In
CRM_Mailing_BAO_Mailing::create
andMailing.create
API, there is a(ahem) special behavior where setting the
scheduled_date
willimmediately trigger scheduling. One shouldn't submit
scheduled_date
for apreview.
See: https://lab.civicrm.org/dev/mail/issues/5
Before
If one tentatively sets a delivery time and previews, then it prematurely schedules a MailingJob.
After
If one tentatively sets a delivery time and previews, then it does not prematurely schedule a MailingJob.
Technical Details
This was not symptomatic before #11142/v4.7.31 because all preview
operations were wrapped in a transaction and rolled back. But now previews
are allowed to have side-effects, so we need some other means to prevent.
This copies the workaround from
crmMailingMgr.save()
and appliesit to
crmMailingMgr.preview()
(etal).
