Please review these test changes which implement automatic testing of container resource updates without JVM restart. Note that this merely tests container detection code handling this case. It doesn't do anything special for the JVM itself, though it might make sense to add some sanity checks should we detect certain limits changing. In another PR, though.
As to the test design, it works similar to the shared temp tests: Interact between the two containers by virtue of a shared filesystem `/tmp` and creating marker files there in order to make them cooperate. Note that the new test needs `podman` version `4.3.0` and better (`4.5` is current). Testing: - [ ] GHA (still running) - [x] Linux x86_64 container tests on cg v1 and cg v2 system - [x] Newly added tests on Linux x86_64 cg v1 and cg v2 (`podman` and `docker`) ------------- Commit messages: - Fix whitespace - 8308090: Add container tests for on-the-fly resource quota updates Changes: https://git.openjdk.org/jdk/pull/14090/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14090&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8308090 Stats: 434 lines in 5 files changed: 431 ins; 2 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/14090.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14090/head:pull/14090 PR: https://git.openjdk.org/jdk/pull/14090
