<div dir="ltr"><div><div><div><div>Now <a href="http://build.squeak.org/job/SqueakTrunk/856/">http://build.squeak.org/job/SqueakTrunk/856/</a> is back to a better red state: one that time out after 20 minutes because of the [Warning signal: 'About to <span>serialize</span> an empty package.']<br>
(like I told in my first mail and like in builds <a href="http://build.squeak.org/job/SqueakTrunk/823/">http://build.squeak.org/job/SqueakTrunk/823/</a> to <a href="http://build.squeak.org/job/SqueakTrunk/833/">http://build.squeak.org/job/SqueakTrunk/833/</a>)<br>
<br></div><div>So applying Chris' fix and repairing the update-stream was not enough to get rid of it.<br></div><div><br></div>The Warning is triggered by #testMcdSerialization<br></div>It appears that (self mockDiffyVersion) has no changes...<br>
</div>Though, mockDiffyVersion tries to change: #a toReturn: 'a2'.<br></div>Something in this test is not working as intended, but here I'll stop for tonight.<br><div><div><div><div><div><div class="gmail_extra">

<pre>MCClassDefinition>>createClass</pre>I encountered this one while updating some of my old trunk images.<br>The definition changed in Monticello-cwp.589:<br>
+ inEnvironment: (CurrentEnvironment signal ifNil: [superClass environment])<br>
- inEnvironment: (EnvironmentRequest signal ifNil: [superClass environment])<br><br>But there is no EnvironmentRequest anymore when loading this definition, so we signal nil, and the load fails.<br>
</div><div>We would have expected this, it's just be renamed in:<br></div><div><br>Environments-cwp.47<br>
Time: 22 March 2014, 7:53:17.666 pm<br><div>
Rename <span>EnvironmentRequest</span> to CurrentEnvironment and use it to implement <span>Environment</span> class>>current.<br><br></div>To be safe, the rename should have been performed in two stages:<br>
</div><div>1) create the new class and migrate customers from the old to the new one.<br></div><div>2) remove the old one<br></div><div>It would thus have required two updates.mcm and not a single one<br>(MC lacks a semantic #rename: so it does not work like in-image-tools)<br>
</div><div></div><div>Unfortunately, update-cwp.48 did perform the two operations at once...<br><br></div><div>Curiously, if I take an artefact from build server and update, the upgrade is then processing fine... Don't ask why.<br>
</div>Since no one complained, I told to myself that it was me not following the standard process, I patched my images manually and restarted the upgrade.<br>But I now see that it's not just me, there is a CI machine too using Squeak trunk (anyone else???)<br>
<br></div>I have to cheat again with mcm surgery:<br></div>- publish an Environments-nice.47 that adds the CurrentEnvironment, but not removes EnvironmentRequest<br></div>- patch update-cwp.48 to point to Environments-nice.47 rather than Environments-cwp.47<br>

</div>I checked the last artefact for squeak trunk:<br><a href="http://build.squeak.org/job/SqueakTrunk/853/" target="_blank">http://build.squeak.org/job/SqueakTrunk/853/</a><br>
<br></div>It's still blocked with the [Warning signal: 'About to <span>serialize</span> an empty package.']<br></div>With this warning, a test never time out (I don't know why exactly, but it seems that theProcess monitored by the timeout watchdog is already suspended by the Warning)<br>
As a result, the tests do never complete and are aborted after 20 minutes...<br><br></div>Chris has fixed the problem since, but it seems that the CI does not upload latest trunk.<br></div>Why?<br></div>It seems to be the same problem as the TestRunner: updating triggers the same [Warning signal: 'About to <span>serialize</span> an empty package.']<br>
</div>Ah Chris, it's irony that it's you who precisely keep on fighting modal UI ;)<br><br></div>Now the question: how do we escape from this situation?<br></div>Shall I cheat and modify the update that is blocking?<br>
<div><div><br><br></div></div></div></blockquote></div></div><div>So I decided to cheat:<br></div><div>I brought update-eem.279 to the surgery block and reverted CommandLine-fbs.3 -> CommandLine-fbs.2<br>CommandLine-fbs.3 tried to be smart and workaround the Warning problem, but before it had a chance to load, it precisely triggered this Warning!!!<br>
</div><div>Since this update is also bringing Chris fix, let's defer CommandLine-fbs.3 to next update (eem-280) and cross fingers...<br></div></div><br></div></div>
