[keystone] Dropping the milestone 2 deadline for API-impacting
blueprints</font>
<br>
<hr noshade>
<br>
<br>
<br><font size=1 face="Arial">Greetings, [keystone]!</font>
<br>
<br><font size=1 face="Arial">First, some history: Early in Keystone's
life (before the integrated gate, tempest, and human-readable API documentation),
our API implementation fluctuated on such a regular basis that it presented
a severe stability risk to OpenStack (particularly late in the integrated
release cycle). To address the situation on the Keystone side, we rapidly
matured our development process and became very wary of API changes. We
document and review proposed API impact before considering the implementation,
guarantee backwards-compatibility for every change we make, and avoid making
*any* core API changes during the last milestone of the integrated release
(this is the "milestone 2 deadline" referenced in the subject).</font>
<br>
<br><font size=1 face="Arial">Since that time, we've raised the bar yet
again for our development process: openstack/keystone-specs. It's clear
that changes impacting our consumers are more well-thought-out and thoroughly
documented than ever before. We also have the integrated gate and and out-of-tree
integration tests to help catch API regressions. Now that our API documentation
is human-readable, we regularly get bug reports citing discrepancies between
our documentation, implementation and/or test suite.</font>
<br>
<br><font size=1 face="Arial">We've made a lot of progress in the last
few releases. With all that additional process maturity, I think it's time
we drop the milestone 2 deadline for API impacting changes. It's always
been a stopgap in the development process designed to catch issues like
backwards incompatibility and API unimplementium. Thankfully, we now have
much better tools in place to weed out those issues, and more importantly,
have a superb core review team capable of utilizing sound judgement on
the acceptability of changes to the core API.</font>
<br>
<br><font size=1 face="Arial">With our milestone-2 deadline for Juno just
around the corner, I've added this topic to tomorrow's keystone meeting
for discussion:</font>
