AppCDS, DynamicCDS, Leyden and JRuby
by Charles Oliver Nutter 14 Feb '25

14 Feb '25

Hello friends, I'm revisiting CDS-related stuff in JRuby today! Claes R. suggested I direct my CDS questions here, since this list represents the future of that work. We are keenly awaiting the new AOTCache stuff but for now I'm looking primarily at AppCDS or DynamicCDS given the upcoming JRuby 10 baseline JDK level of 21. So, I have a JRuby launcher script that already can detect and use a jsa generated for JRuby into the install location. I'm adding a flag to run -XX:ArchiveClassesAtExit and have a few questions: * OMG that warning output... is there any way to capture that to a file without redirecting the whole process? * Why is it not possible to boot with one JSA and then dump a new JSA at the end? It complains if I use both SharedArchiveFile and ArchiveClassesAtExit in the same command line. * Is there any way to verify if the JSA will be usable (not stale, etc) without parsing stderr output from the failed attempt to use it? Basically I'm trying to make this a hidden automatic feature in the JRuby launcher: if the JSA doesn't exist, generate and use it; if it's stale because JRuby or JDK changed, regenerate and use it. That's hard to do if it's spitting warnings at my users. *Charles Oliver Nutter* *Architect and Technologist* Headius Enterprises https://www.headius.com headius(a)headius.com

JRuby and JDK24 AOTCache experiment
by Charles Oliver Nutter 14 Feb '25

14 Feb '25

I figured folks here would be interested to see this experiment using AOTCache with JRuby. https://gist.github.com/headius/1a5cfbc91ed8bacd194f1c592a90c275 I just test the 'hello world' scenario that represents our baseline startup, but AOT caching manages to beat the automatic AppCDS startup by a bit. More/better training might help here I'm guessing? This is from the JRuby 10 branch (10-dev) on https://github.com/jruby/jruby.git if anyone wants to play with it. Just run `./mvnw` and then `bin/ruby` will work. We recently added support for AutoCreateSharedArchive so it will use CDS by default. Pass --nocache to disable that behavior. *Charles Oliver Nutter* *Architect and Technologist* Headius Enterprises https://www.headius.com headius(a)headius.com

RFR: Store AOT code in cached code region of AOT cache
by Ashutosh Mehra 13 Feb '25

13 Feb '25

This PR stores AOT code in the cached code region of AOT Cache. Some things worth pointing out: 1. Before this patch: the AOT code is first generated in a temporary buffer. After all the code is generated, this temporary buffer is copied into second buffer (allocated in native heap) for multiple reasons. This second buffer is then stored in the file as is. With this patch the second buffer is now allocated in the cached code region which is part of the AOT cache. So now the cached code region contains the permanent oops table (which already exists before this patch) and the AOT code+data. 2. I have removed `_jvm_version_offset` from the SCCHeader. AOT Cache already stores VM identifier which should cover it. 3. I have to remove the code that maps cached code region to CodeCache because the contents in cached code region are not CodeBlobs. The cached code region can be mapped to any random address. 4. I have replaced references to "Startup Code Cache" with "AOT Code Cache" or "AOT Code". ------------- Commit messages: - Store AOT code in cached code region of AOT cache Changes: https://git.openjdk.org/leyden/pull/39/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=39&range=00 Stats: 321 lines in 12 files changed: 34 ins; 186 del; 101 mod Patch: https://git.openjdk.org/leyden/pull/39.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/39/head:pull/39 PR: https://git.openjdk.org/leyden/pull/39

RFR: 8349905: [leyden] Make SCCache depend on CDS build feature
by Aleksey Shipilev 12 Feb '25

12 Feb '25

As we are moving more SCCache code to CDS archives, we need to start depending on CDS feature being enabled during the build to get access to SCCache stuff. A common configuration where CDS is not available is Minimal VM. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/40/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=40&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349905 Stats: 31 lines in 3 files changed: 3 ins; 1 del; 27 mod Patch: https://git.openjdk.org/leyden/pull/40.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/40/head:pull/40 PR: https://git.openjdk.org/leyden/pull/40

RFR: 8349713: [leyden] Memory map the cached code file
by Aleksey Shipilev 12 Feb '25

12 Feb '25

It is visible in profiles for lots of applications that reading the SC cache file at startup costs significantly. On JavacBenchApp example, loading ~25M code requires about 30ms. This is ~1 GB/sec, so it is I/O limited. We should really mmap the SC cache file to alleviate these costs. Let the actual SC readers (separate threads) to eat the cost of reading from the backing file. I was not entirely sure COW for file mappings works correctly on Windows, so I excepted that one.
