2025-01-30: It was hard to maintain a hand-crafted suite.yml, so I made initial hacks to the suite-generator code to generate suite.yml files for jscore_passthrough tests using the MongodumpReplicator. Have to learn the idioms of evergreen tasks/funcs as I go, so moving slowly, but that's useful knowledge for the future. I got to look at logfiles, and found I was trying to launch a copy of a MacOS mongodump executable on a RHEL-8 evergreen worker, so obviously that wouldn't work. Currently working on changing the mongo-tools/common.yml and shell scripts to be able to build both mongo-tools and mongosync on the evergreen worker. I hoped to reach milestone 1 without tackling that, but I spent a while trying some simpler kludges and couldn't get them to work. 2025-01-17: REP-5481 MongodumpReplicatorFixture is about 95% coded, I'm doing some ugly temporary hacks to drive it from a slightly-modified mongosync passthrough task .yml, and I think it's being set up but so far it fails too early to get a logfile. 2025-01-08: Technical design approved 5 Jira tickets created for the milestone 1 work (get one test to run) mongodump --internalOnlySourceWritesDoneBarrier code complete, not yet tested mongodump_replicator.py coding in progress 2024-12-06: The engineers working on the project had been focused on correctness and longer term initiatives for some of the last month. The technical design is close to being approved. 2024-10-24: The technical design is in progress.
