Christoph Thiede uploaded a new version of Collections to project The Trunk: http://source.squeak.org/trunk/Collections-ct.1003.mcz ==================== Summary ==================== Name: Collections-ct.1003 Author: ct Time: 2 April 2022, 1:46:18.637455 pm UUID: 8f588405-6ab6-2342-8fe8-ebdaff0733ea Ancestors: Collections-ul.1002 Corrects merge slip from Collections-ul.1001 which had reverted Collections-ct.999.

Christoph Thiede uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-ct.1333.mcz ==================== Summary ==================== Name: System-ct.1333 Author: ct Time: 1 April 2022, 1:08:01.825996 pm UUID: f206069e-de00-fb40-b100-69e1871c1490 Ancestors: System-ul.1332 Merges robust-forceChangesToDisk.1.cs: Increases the robustness of Smalltalk forceChangesToDisk. When this method is interrupted, make sure to maintain the invariant that the source file is always opened and set to the right position. In the course of this, also makes StandardFileStream>>#open:forWrite: more robust. Adds a smoke/regression test. For context: Interrupting Smalltalk forceChangesToDisk is not a fictional scenario. In combination with a slow file system access, I could reproduce this many times when running StringTest>>#testPercentEncodingJa with a too small timeout.
