Subject: Jtreg tests with JNI native code on static JDK
Message-ID: <CALrW1jwUbO9TZr3XZxsy5n-vJ+et_Zcg5MyiV6B9k_WMnUA_+w@mail.gmail.com>

With the recently enhancements in JDK mainline (thanks for all
contributions to the related work), it's able to build a static-jdk image
(support a static-jdk/bin/java launcher executable statically linked with
JDK/hotspot native), and able  to execute jtreg tests on the static-jdk
image. While the JDK mainline is reaching this milestone, I think it would
be good to start a conversation to seed the brainstorm on jtreg testing on
static-jdk image, specifically for tests with JNI natives.

For jtreg tests with native, the native code has normally been linked into
shared libraries. JEPS 178 <https://openjdk.org/jeps/178> enhanced JNI
specification to support statically linked native libraries. As a result,
we could build the jtreg test native code into static libraries and link
those with the static-jdk/bin/java launcher. An obvious alternative is to
continue building the jtreg test native code in shared libraries for
testing on static-jdk images. The alternative is feasible (the current
leyden/tree/hermetic-java-runtime
<https://github.com/openjdk/leyden/tree/hermetic-java-runtime> branch can
be used to demonstrate this capability). It's probably also a less
disruptive solution for running jtreg tests on static JDK using today's
existing testing framework/setup.

There are some pre-existing assumptions about dynamic loading and linking
native libraries in the tests (we have addressed and resolved many of those
in JDK and VM in JDK mainline already). For both approaches described in
above paragraph, we would need to remove these assumptions from the jtreg
tests regardless which approach is used for building/packaging the test
native code. Would be great to see this brief writeup brings in more
thoughts and discussions on the Jtreg testing strategy on static JDK.
Thanks!

Best,
Jiangli

500x runs of `TestConcurrentPatching.java` passes. `all` test suite passes without regressions (there are some Leyden-specific problems that reproduce even without this patch). I would like to integrate this version, if you agree @iwanowww?

There is also the "portability" aspect of the compiled code.
I know it has come up for discussion in the past, but I don't remember if
we decided to do anything about it.
If we are planning to move things to the mainline, then probably this is a
good time to revisit it.

I think @nizarbenalla had added similar support for Valhalla-specific new APIs, so using the current version is not the best approach. Forgot where this is handled exactly unfortunately.

Thanks for the ping. David Simms added that support in the Valhalla repo https://github.com/openjdk/valhalla/pull/1312, so I didn't end adding it to mainline.

I will try to add support for non-numeric values this week, otherwise you will need to up update the `@since` info every 6 months.

Statically linking native test libraries seems strange to me. If we 
think of a test case as a user of the Java runtime, it should not matter 
whether the Java runtime is a hermetic image or not, and dynamic linking 
of native libraries should continue to work as before, I think. Unless 
I'm misunderstanding the goal of hermetic images, it is still possible 
to dynamically load e.g. jar files with a hermetic Java image, right? 
Those jar files could contain/depend on dynamic native libraries, so I 
think either way those need to be supported.

Could you give some examples of the assumptions you're talking about here?

I assume these changes aren't strictly needed (`_queue` is always drained under the lock).

One example is test/hotspot/jtreg/runtime/jni/atExit/TestAtExit.java.
When building libatExt, it explicitly links with libjvm.so (e.g. on
Linux), which becomes a recorded dependency of libatExit.so:

https://github.com/openjdk/jdk/blob/618c5eb27b4c719afd577b690e6bcb21a45fcb0d/make/test/JtregNativeHotspot.gmk#L883C40-L883C49
```
BUILD_HOTSPOT_JTREG_LIBRARIES_JDK_LIBS_libatExit := java.base:libjvm
```

```
$ ldd ./build/linux-x86_64-server-release/support/test/hotspot/jtreg/native/lib/libatExit.so
linux-vdso.so.1 (0x00007fb80017c000)
libjvm.so => (snip)
...
/lib64/ld-linux-x86-64.so.2 (0x00007fb80017e000)
```

Runtime linker and loader would resolve and load the dependency
`libjvm.so` when loading `libatExit.so`. As static-jdk does not
provide `libjvm.so`, it would fail when running the test using the
static-jdk. I filed https://bugs.openjdk.org/browse/JDK-8349178.

The good thing is so far testing only has found just a few such cases
in Tier1 tests.

Best regards,
Jiangli

So does this mean that any test (or application) that uses JNI and has 
to link to libjvm will need to be modified to work with a statically 
linked JDK?

While `_queue` is drained under the lock, it is being _added to_ without a lock, which means we are using `empty` under concurrent queue modification, which is, per NBQ docs, not guaranteed to work well. (ABA problems.)

David, please see my responses in
https://github.com/openjdk/jdk/pull/23431#issuecomment-2634531490:

JNI functions are already dynamically called. E.g. in the same test here:


    res = (*jvm)->AttachCurrentThread(jvm, (void **)&env, NULL);


We don't need to change those at all to work on static-jdk. The existing
design of JNI functions can work on both dynamic JDK and static JDK.


The calls fixed by this PR are the very few exceptions that do not follow
the design principle. I do think we should fix them by following the right
patterns/conventions. Note LoadJavaVM in JDK code calls these functions
'properly', see jdk/src/java.base/unix/native/libjli/java_md.c.


So far I've only found this test in hotspot tier1 and libExplicitAttach
(AttachTest_id0) in JDK tier1 with the issue.


@dholmes-ora If we don't go with this change, do you have any other
suggestions? One other possible alternative that I can think of is using
weak symbols, however I think that's no better.


and https://github.com/openjdk/jdk/pull/23431#issuecomment-2634595988:

Also to point it out if it's not clear already, libjvm.so is implementation
detail. One cannot safely exist at runtime. The static JDK case is a good
example.


Best,
Jiangli

Thanks for the clarification. I missed that `NonblockingQueue::empty()` is not thread-safe.

Subject: Add static-jdk build in GHA
Message-ID: <CALrW1jz9npybbioiL8Gki6Uae56wKMxTgu-z-oqHSpqCwi0LMA@mail.gmail.com>

With the current state of JDK mainline for static JDK support, it's a good
time to add 'static-jdk' build as a minimum/initial pre-integration check
in GHA. It helps catch regressions accidentally introduced in any new
changes that could break the static JDK build (e.g. duplicate symbols in
different JDK native libraries). We have also discussed this topic during
the on-going hermetic Java zoom meetings with Ron, Alan, Magnus and others.
As a starting point, we can add release and fastdebug static-jdk builds on
linux-x64 for now, and then expand to other platforms when appropriate.

Here are some measurements that I collected from building jdk-image and
static-jdk-image for release and fastdebug binaries on my local linux x64
machine (with gcc as the default). For release build, building jdk-image
and static-jdk-image takes about the same real time. For fastdebug,
building a static-jdk-image takes ~1m more than building a jdk-image on my
linux machine. Thoughts and additional suggestions are welcome!

Clean builds
==========

jdk-image:
----------------
release: real 2m20.327s
fastdebug: real 3m0.262s

static-jdk-image:
----------------------
release: real 2m51.024s
fastdebug: real 4m11.928s

Jiangli

All right, thanks! I see https://github.com/openjdk/jdk/pull/23447 that implements non-numeric literals. Meanwhile, I think we can push this change to Leyden repo to make tests cleaner, and then replace `@since` with non-numeric literal.

Pull from current `premain` to get the compile queue bugfix, that should turn GHAs green.

Currently, supplying `-XX:-TieredCompilation` would break with Leyden workflows, because the archive-backed code cache heap would only be created if `SegmentedCodeCache` is enabled. With default compilation policy, this happens normally when tiered compilation is enabled, but not without it.

There are other minor peculiarities that we need to handle, which are exposed with `runtime/cds` + `-XX:-TieredCompilation` runs.

This prevents us from testing C2-only Leyden configs and studying compilation dynamics without tiered policy getting in the way.

Additional testing:
 - [x] Ad-hoc Leyden experiments now work with `-XX:-TieredCompilation`: the C2-only code is being stored and loaded successfully from the CDS archive
 - [x] `runtime/cds` now passes with `-XX:-TieredCompilation`
 - [ ] `runtime/cds` still passes by default (i.e. with tiered compilation)

How does this work as far as consistency between training/assembly run and production run is concerned? Do we need to enforce the same setting across these runs or can we e.g. train and then (assuming we fork) assemble with -TieredCompilation but run in production with +TieredCompilation -- or vice versa?

Do we need to enforce the same setting across these runs or can we e.g. train and then (assuming we fork) assemble with -TieredCompilation but run in production with +TieredCompilation -- or vice versa?

I tested different combinations of `{+|-}TieredCompilation` with training and production runs, and it works well. I believe the normal mechanisms make it right. No C1 code? Nothing loaded. C1 code in archive, but C1 is disabled? We are not loading it then. 

In fact, there seem to be a slight performance edge in training with C2 only, and then running with C1+C2: no penalty on loading lots of C1 compiled code, and quicker transition from intepreter to "real" C1 in only a few places where it is needed! Compiler dynamics is weird.

WIP. I have yet to see if this has a good performance impact.

Studying the bailout reasons for JavacBenchApp, I notices the majority of nmethod store bailouts are due to referencing the hidden klasses. Those checks seem to be from the initial commit. I wonder if we can actually skip hidden klass checks, now that we archive lots of those since invokedynamic AOT was implemented.

Look at "user" time, this is what we save without recompiling the methods that get bailed from the archive.

Compiler dynamics is weird. This PR gains us access to these kind of studies :)

As I mentioned during the meeting, it looks weird to me to see `if (TieredCompilation)` checks in Precompiler code which is executed only during assembly phase. As a data point, regular CDS archive is used to be generated in interpreter-only mode (to make the process reproducible). 

Instead of supporting arbitrary JVM configurations during assembly phase, I'd prefer to see offending JVM parameters being overridden/dropped.

I agree that the restriction for hidden classes can be lifted.

But there are non-default modes where it still matters (`UseMetadataPointers == true`). 
I suggest to keep `klass->is_hidden()` check, but move it down to guard symbolic resolution case.

> Studying the bailout reasons for JavacBenchApp, I notices the majority of nmethod store bailouts are due to referencing the hidden klasses. Those checks seem to be from the initial commit.

Aleksey Shipilev has updated the pull request incrementally with one additional commit since the last revision:

FWIW, I believe `UseMetadataPointers` is `true` by default. Turning it off starts to fail `runtime/cds`.

Could you point me where exactly? I think there is a fair amount of symmetry against the hidden method checks here, so I moved the check to the same place:

> Studying the bailout reasons for JavacBenchApp, I notices the majority of nmethod store bailouts are due to referencing the hidden klasses. Those checks seem to be from the initial commit. I wonder if we can actually skip hidden klass checks, now that we archive lots of those since invokedynamic AOT was implemented.

Right, I thought it matters for Precompiler not to attempt pre-compiling C1 classes with `-XX:-TieredCompilation`, but it does not. I see `runtime/cds` passing with/without TieredCompilation without these hunks, and CDS archive sizes are similar, and performance is still the same. So I have reverted Precompiler hunks as unnecessary.

Take a look again?

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.

Additional testing:
 - [x] Linux x86_64 server fastdebug, `runtime/cds`

It demonstrably improves performance on Linux, kicking out the 30ms out of critical startup path.

There are lots of mainline reports about this test, see links. We see a failure in current GHA for Leyden. For Leyden, there are additional specifics: we print advanced compile task information in compile log, so we get indenting/format mismatches.

Leyden dumps this:


     57 W0.0 Q0.0 C0.7 3 b compiler.inlining.LateInlinePrinting$TestLateInlining::test2 (7 bytes)

So, this bug fixes the test for Leyden specifically, while mainline is figuring out the rest.

@shipilev 

Does the numbers still holds with

sync; echo 3 > /proc/sys/vm/drop_caches

before the benchmark (single shot) run?
With big servers, unless there's some expected sharing (i.e. multiple processes using the same archive) to further boost it, I would expect direct I/O to benefit loading the archive by saving the extra copy (in the OS page cache) required to use the data read (OS page cache + extra copy).
The other concern re mmap is due to munmap cost which, on kernel side, relies (IIRC) to some v page single (!) lock to guard it - which usually slowdown processes termination

During one of the meetings, @iwanowww suggested there is a diagnostic option to block the execution until all preloaded code is finished loading. For the Java application, it would then look as if the entirety of preload code was loaded "instantaneously", which helps to estimate the performance floor for a given workload.

I have found no such option in current Leyden prototype, though, so this RFE should implement one. 

This is indeed helpful, especially combined with #32, which allows to run with only C2.

Yes, they do, and there is a good reason why: without caches, the hit on the critical startup path is even worse, even with a modern SSD. And AFAIU, file-backed mmap does play well with I/O caches too. Observe:

`hyperfine` tests of mine include that cost, as they are end-to-end invocation tests. (I remember this from 1BRC times.)

I started implementation of Code caching using only symbolic resolution in relocations. When it is integrated with other changes I left such capability guarded by this flag.
We can retire this flag when the only way to use code caching is CDS archive which will contain the code instead of separate file. I am currently looking on this.

Good.  Until, as we discussed, cached code (and its data) will be part of CDS archive file.

How CDS handles `mmap` on windows?

Yes, that would make this whole thing no-op. CDS mmap-s the archive already.

> How CDS handles `mmap` on windows?

Windows can still memory-map the file through its Windows APIs. But I _vaguely_ recollect some corner cases that @iklam fights every so often. Something with remapping or so? See `MetaspaceShared::use_windows_memory_mapping`, for example. I don't think it is wise to spend time dealing with those corner cases in current Leyden prototype, let it be part of whole CDS archive first.

I think this would impact the code archive, not the CDS archive. 
If it does reduce the on-disk size of code archive, then why not do this? It's pretty straightforward; not a complicated change IMO.

So I have reverted Precompiler hunks as unnecessary.

I looked at both `.cds` and `.cds.code` files, and they are of similar size with `-XX:-TieredCompilation` whether we have this runtime check or not. I suspect this is because with `-XX:-TieredCompilation` we _do not have_ C1 compilations at all, so there is nothing to precompile. This makes the code change redundant.

I was thinking may be set `BackgroundCompilation` flag to `false` temporary in `SCCache::preload_startup_code()` which loads all startup code. We do similar thing when dumping CS archive:
https://github.com/openjdk/leyden/blob/premain/src/hotspot/share/cds/cdsConfig.cpp#L547

But I am not sure how such temporary setting affects `directive->BackgroundCompilationOption`.

src/hotspot/share/compiler/compiler_globals.hpp line 494:

> 492:           "Exit after precompilation step is over")                         \

> 494:   product(bool, PreloadBlocking, false,                                     \

Should be diagnostic flag

> Studying the bailout reasons for JavacBenchApp, I notices the majority of nmethod store bailouts are due to referencing the hidden klasses. Those checks seem to be from the initial commit. I wonder if we can actually skip hidden klass checks, now that we archive lots of those since invokedynamic AOT was implemented.

Subject: Leyden PRs and repo-leyden bugs
Message-ID: <b0268d2f-7cf6-4f67-8966-977900ee515c@amazon.de>

(cc'ing leyden-dev@)

Hi Skara devs!

I was wondering what kind of config Leyden repo is missing, so that PRs are not closed 
automatically? See for example this bug:
   https://bugs.openjdk.org/browse/JDK-8348960

...and here is the integrated PR:
   https://github.com/openjdk/leyden/pull/30

I suspect the problem might be that PRs are targeting the "premain", not "master" branch? Is there a 
way to tell bots to treat "premain" branch as repo-leyden, maybe?

Here is jcheck for premain branch:
   https://github.com/openjdk/leyden/blob/premain/.jcheck/conf

Thanks,
-Aleksey

> Currently, supplying `-XX:-TieredCompilation` would break with Leyden workflows, because the archive-backed code cache heap would only be created if `SegmentedCodeCache` is enabled. With default compilation policy, this happens normally when tiered compilation is enabled, but not without it.

hmm ... I just tried your original patch with [quarkus-getting-started](https://github.com/openjdk/leyden/tree/premain/test/hotspot/jtreg/premain/quarkus-getting-started) test and see the size of `.cds.code` goes down from `4816316` to `1459860` and `.cds` came down from `38363136` to `36966400`

Do you see the same kind of improvement with new version of the patch and `-XX:-TieredCompilation`?

aah! I get it now. For some reason I kept thinking we are not able to run with `-XX:-TieredCompilation` in the training/assembly run and this particular hunk fixes it. But that's not the case. My bad!

No problem! The interactions between different phases and compiler tiers are often confusing :)

See `MetaspaceShared::use_windows_memory_mapping`, for example. I don't think it is wise to spend time dealing with those corner cases in current Leyden prototype, let it be part of whole CDS archive first.

With the Windows APIs used by HotSpot today (VirtualAlloc and MapViewOfFile), we can't map a file into a reserved region. If we just want to mmap the SCCache into non-reserved, random location that's picked by the OS, we can already do that today with HotSpot.

In some cases, CDS wants to mmap into reserved regions. On Windows, we end up not mapping with MapViewOfFile, but simply reading the entire CDS file into reserved memory.

I think with this new API [MapViewOfFile3](https://learn.microsoft.com/en-us/windows/win32/api/memoryapi/nf-memoryapi-mapviewoffile3), we can map into a reserved region. This would be useful if, for example, we want the SCCache to be immediately next to CDS, so that the AOT code can use relative addressing for metadata pointers (InstanceKlass*, etc).

OK, great. AFAICS, this technically allows us to do `MmapCachedCode = true` on Windows too. Non-Windows currently rely on `MAP_PRIVATE` to get us COW. I believe `FILE_MAP_COPY` in `os::pd_map_memory` gives us the same on Windows.

Still, I think it is a bit saner to keep doing mmap-ing only on Linux, if only to test that non-mmap path works and not force us to debug Windows mmap issues in Leyden prototype. But I don't feel strongly about this. Opinions welcome!

Subject: RFR: 8349748: [leyden] ciEnv::register_method should lock the correct

Mainline code locks `MethodCompileQueue_lock` in `ciEnv::register_method`. But with Leyden-s `UseGlobalCompileQueueLock = false`, we have separate locks, per compile queue. So it seems to stand to reason we should be locking those locks, not a global one.

I have not been able to attribute this gap to any bug or performance issue, but I think we better fix this proactively.

I don't think it works well. AFAICS, default compiler directives get initialized off the global `BackgroundCompilation` option at init time, through `DirectivesStack::init` during `CompilerBroker` init.  The dumping CS path you linked above works, because it adjusts the global flag during arguments processing, before compiler broker is initialized. 

For our use here, it is too late to flip `BackgroundCompilation` to `false` and back.

Looks good. 

FTR I experimented with bulk preloading to speed up things (submit all preload tasks and block waiting until all are finished), but it turned out to require significantly more code for no particular benefit (the mode is not performance critical and, compared to compilation, preloading is already fast enough).

Good catch. Looks good.

FTR I suspected the locking here is redundant, but haven't had enough time to build enough confidence to get rid of it.

Preload code is the C2 code we load very early, before it gets substituted by more advanced C2 code. We are seeing lots of uncommon traps from the preloaded code, though, which invalidates it too early. We can do precompile code without uncommon traps to alleviate this. 

Additional testing:
 - [x] Ad-hoc perf tests (see comment below)
 - [x] Linux x86_64 server fastdebug, `runtime/cds`

Since this avoids excess C2 (re-)compilations, the major impact is on "user" time. This impact reflects to run-to-run times when we are short on available CPU cores:

I think this looks fine. The change is small, so we can update or remove it when migrating the SCCache into CDS.

Why don't you instrument `Compile::too_many_traps()` instead? (Check for compilation reason and unconditionally return true when compiling code for preloading.)  

Also, it would be useful to make new logic conditional (controlled by a diagnostic flag). It would make it easier to measure deoptimization-induced performance effects at runtime.

At some point, I added SCC-related info to `TraceDeoptimization` output [1], but it turns out I didn't upstream it. (I had a script which parsed the log and aggregated information about deopts in archived code.) 

Maybe it's better to upstream it instead of introducing such adhoc logging.

But speaking of monitoring for uncommon traps in generated code: the ultimate goal may be to completely eliminate uncommon traps in preloaded code. In that respect, it's more interesting to monitor for all uncommon traps issued during compilation rather than those hit at runtime. 

For C2 it's `GraphKit::uncommon_trap()`, so I suggest to move the code there. Also, additional information about compilation (id) and location (jvms info) is useful to pin down the root cause.

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".

hmm, now I am not sure if this is really required. We can map the cached code region to CodeCache and still use it in SCCache.

Can we leave this part of code but not use it - map to random address for these changes?

It was prepared for "preload" AOT nmethods so we can use them immediately (after your work on caching whole nmethod). Normal AOT nmethods (tier1-4) may live in separate space until they are requested - we can't publish (patch) them until corresponding classes are initialized.

Yes, we can do that. It would also mean the ReservedSpace created by CodeCache would just be a lot bigger now by the size of the cached code region. But again it would only affect the virtual memory, as we are not mapping anything to that space. And hopefully this would just be temporary.

@vnkozlov pushed a change for mapping the cached code region separately from the CodeCache.

Minimal is tricky. Now SCCache depends on CDS archive, so ideally its functionality should be guarded by INCLUDE_CDS and other CDS related macros.

I think this PR would be superseded by @ashu-mehra's #39. We can still do it ahead of #39, removing the flag and accepting all platforms.

Minimal is easy enough to fix, we just need to clearly introduce dependency on CDS, see #40.

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.

All right, the flag stays for a while. Once Ashu moves this whole thing to CDS, we can remove the flag. Meanwhile, we only do mmap on Linux. I think we are ready to integrate this.

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.

Please add comment about `ReservedCodeCacheSize`. Why not `CachedCodeMaxSize`?

src/hotspot/share/code/codeCache.cpp line 359:

You can undo that to avoid changing file.

test/hotspot/jtreg/premain/lib/DemoSupport.gmk line 163:

I would just remove this line.

Oh nice! I didn't know about this. Yesterday I was sprinkling INCLUDE_CDS in SCCache.cpp because it was getting compiled in the minimal config.

Yup. This is a nuclear option in the build system! For your other PR, you might need to stub out more things with `NOT_CDS*` in `SCCache.hpp` to make things work.

Subject: AppCDS, DynamicCDS, Leyden and JRuby
Message-ID: <CAE-f1xQtjsXoh3gEAfjKBM33Dcmj2SrFDUTnGC4Lg4T_xs5LoQ@mail.gmail.com>

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.

Yeah, I think that makes sense. Since the aot code buffer is based on CachedCodeMaxSize, we can use this for sizing cached code region as well.

Alexey Shipilev directed me toward the -Xlog flag to silence the CDS
output, which seems to work pretty well. I wish I could direct this to
/dev/null, though!

-Xlog:cds=off -Xlog:cds=warning:file=jsa.log

This would also silence the stale JSA warning. My second question stands,
though: why can't I incrementally add to the JSA by starting up with it AND
dumping a new one at the end?

Did you measure any performance with this change?

src/hotspot/share/code/SCCache.cpp line 162:

Missing "AOT" in "Code Cache"

src/hotspot/share/code/SCCache.cpp line 1043:

Should you compare to `CachedCodeMaxSize`? Also missing `Code` in "AOT Cache".

Hi Charlie,

Thanks for trying CDS out. Is there any performance numbers you can 
share with us?

That's something we are talking about in the Leyden project - train with 
an existing cache and write an updated cache at the end. What kinds of 
scenarios are you looking at?

Have you tried the -XX:+AutoCreateSharedArchive flag? It should recreate 
the dynamic archive if you have updated the app's JAR files or updated 
to a new JDK.

See https://docs.oracle.com/en/java/javase/21/docs/specs/man/java.html

Thanks

Sure! Here's a few JRuby command lines before and after with JDK 21 CDS:

Hello world, with and without --dev flag (--dev limits to tier 1, disables
JRuby JIT):

jruby -e 1  2.52s user 0.13s system 183% cpu 1.447 total
jruby --dev -e 1  1.16s user 0.12s system 125% cpu 1.014 total

With CDS:

jruby -e 1  1.78s user 0.10s system 192% cpu 0.979 total
jruby --dev -e 1  0.92s user 0.09s system 120% cpu 0.834 total

List all installed libraries (gems):

jruby -S gem list > /dev/null  5.24s user 0.23s system 215% cpu 2.532 total
jruby --dev -S gem list > /dev/null  2.15s user 0.21s system 112% cpu 2.089

jruby --dev -S gem list > /dev/null  1.76s user 0.13s system 131% cpu 1.437
total

List all build targets in current project (rake):

jruby -S rake -T > /dev/null  4.58s user 0.25s system 143% cpu 3.363 total
jruby --dev -S rake -T > /dev/null  1.99s user 0.20s system 81% cpu 2.682
total

With CDS:

jruby -S rake -T > /dev/null  3.97s user 0.23s system 141% cpu 2.977 total
jruby --dev -S rake -T > /dev/null  1.77s user 0.18s system 78% cpu 2.476
total

The CDS improvements are comparable on their own to --dev, which is great,
and combining them with --dev is even more impressive. The CRuby numbers
are still 10x faster, but this is getting into a range where the difference
is tolerable.

I'm hoping AOTCache can help us eliminate the need for --dev. Tier 2 code
is still much slower than tier 1 code.

My interest right now is entirely startup time, which is honestly the only
reason JRuby hasn't seem more success in Ruby shops. When we take 10x
longer to start up small commands, people just walk away.

Longer term, we are interested in pre-training the AOT cache specific to a
user's application, suitable for deploying a hotter image to a server. I
have also been exploring CRaC for that, but it has serious limitations.

We are looking forward to a future where we can precompile all of the Ruby
standard library to JRuby .class output and have it boot up with cached AOT
for whatever you happen to use during your command. We're also planning to
start pre-generating CDS stuff when publishing container images for e.g.
Docker.

This is definitely what we want for the JRuby launcher! I've integrated it
into the launcher and it seems to work well (my log redirects must still be
included to silence CDS warnings, though):

$ rm -f lib/jruby.jsa
$ time bin/jruby.sh -e 1
bin/jruby.sh -e 1  2.90s user 0.22s system 139% cpu 2.230 total
$ time bin/jruby.sh -e 1
bin/jruby.sh -e 1  1.79s user 0.11s system 176% cpu 1.081 total
$ ls -l lib/jruby.jsa
-r--r--r--  1 headius  staff  32489472 Feb 12 16:14 lib/jruby.jsa

I'm keen to play with the preview of AOTCache in 24. If anyone else wants
to try this stuff with JRuby, building JRuby is just "clone repo" and then
"run ./mvnw". The launcher is bin/jruby at that point and it's just POSIX
shell.

Looks good overall. Some minor comments.

Also, I think you should remove `aotFile` from test/lib/jdk/test/lib/cds/CDSAppTester.java

src/hotspot/share/cds/cdsAccess.hpp line 59:

> 57:   static void test_heap_access_api() NOT_CDS_JAVA_HEAP_RETURN;
> 58: 
> 59:   static void* allocate_from_code_cache(size_t size) NOT_CDS_JAVA_HEAP_RETURN_(nullptr);

I think the following functions should be marked as `NOT_CDS_RETURN`. In the cpp file, they should be moved outside of the `INCLUDE_CDS_JAVA_HEAP` block:


void* CDSAccess::allocate_from_code_cache(size_t size)
size_t CDSAccess::get_cached_code_size()
void CDSAccess::set_cached_code_size(size_t sz)
bool CDSAccess::is_cached_code_region_empty()
bool CDSAccess::map_cached_code(ReservedSpace rs)

src/hotspot/share/code/SCCache.cpp line 409:

> 407: };
> 408: 
> 409: // Skeleton code for including cached code in CDS:

The comment "Skeleton code for including cached code in CDS" should be changed to something like "Storing AOT code in CDS"

In addition to Vladimir's comments above, I also found this greatly expands the size of generated code for preloading, which leads to expanded code buffers, which makes more methods ineligible for SCC. So the net effect can be negative. This PR is on hold until I figure out a way out of this.

Hi Charlie,

> I'm hoping AOTCache can help us eliminate the need for --dev. Tier 2 code is still much slower than tier 1 code.

Did you mean Tier 3 vs Tier 1? Our observations are Tier2 overhead is quite modest (~10%).

In case you observe severe performance degradation between Tier 1 and Tier2, please, share a benchmark to try.

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.

You're right, it's not much, but it's not zero... and limiting to tier 2
wouldn't accomplish anything for us, since any profile data it collects
would never be used.

Here's default (tiered up to 4) versus limiting to tier 3, 2, and 1 for
JRuby baseline startup (hello worldish):

Which build of JDK 24 (or mainline) are you using? There's a recent 
change that turns on -XX:+AOTClassLinking automatically to take 
advantage of all JEP 483 optimizations (including the AOT-linking of 
lambdas)

https://bugs.openjdk.org/browse/JDK-8348752

If you're using an older JDK 24 build (earlier than JDK 24-b35), you 
might need to add -XX:+AOTClassLinking explicitly.

A good way for checking is with -Xlog:cds,class+load and see how many 
classes you are loading from CDS vs dynamically parsed.

Thanks

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.

I'm running the RC from last week:

$ java -version
openjdk version "24" 2025-03-18
OpenJDK Runtime Environment (build 24+36-3646)
OpenJDK 64-Bit Server VM (build 24+36-3646, mixed mode, sharing)

But perhaps the fix I need is not in this build? I ran the record and
create steps again with -XX:+AOTClassLinking and performance wasn't
substantially changed.

I do see lines like this, though, when I enable logging:

[0.895s][info][class,load]
org.jruby.util.io.FilenoUtil$ReflectiveAccess$$Lambda/0x8000004ea source:
shared objects file
[0.895s][info][class,load]
org.jruby.util.io.FilenoUtil$ReflectiveAccess$$Lambda/0x8000004eb source:
shared objects file

Thanks

I am seeing two peculiar warnings in the log file while using this flag:

[0.001s][info][cds] optimized module handling: disabled due to incompatible
property: jdk.module.path=/Users/headius/work/jruby/lib/jruby.jar

This is not a property I'm setting. The full command line for this JRuby
execution is here:

/Library/Java/JavaVirtualMachines/zulu-21.jdk/Contents/Home/bin/java
@/Users/headius/work/jruby/bin/.jruby.java_opts
@/Users/headius/work/jruby/bin/.jruby.module_opts -Xss2048k
-XX:+AutoCreateSharedArchive
-XX:SharedArchiveFile=/Users/headius/work/jruby/lib/jruby.jsa -Xlog:cds=off
-Xlog:cds+dynamic=off
-Djffi.boot.library.path=/Users/headius/work/jruby/lib/jni
-Djava.security.egd=file:/dev/urandom --module-path
/Users/headius/work/jruby/lib/jruby.jar -classpath :
-Djruby.home=/Users/headius/work/jruby
-Djruby.lib=/Users/headius/work/jruby/lib -Djruby.script=jruby
-Djruby.shell=/bin/sh org.jruby.Main -e 1

The java_opts file is empty and the module_opts file just has some
add-opens we need.

[0.001s][warning][cds] AutoCreateSharedArchive is ignored because
/Users/headius/work/jruby/lib/jruby.jsa is a static archive

I have no idea what this means. Once I get in this state it complains every
startup and will also refuse to overwrite the "bad" jsa file. I had thought
that it would overwrite the file if it could not use it, so I don't have to
manually separate CDS archives from different JDKs... did I misunderstand?

Subject: RFR: Fix SCCache stats logged on exit
Message-ID: <DY1hfOHWWaJsLuKDhE43TsGzXBKfvUuGtLXKirfvt20=.a5f55acf-28b2-45c8-944a-e62123fb40d3@github.com>

The count of various SCCEntry kinds is not correctly computed. This patch fixes it.
This code was introduced as part of i2c2i adapters and was picked up from Andrew Dinn's work on storing stub and blobs. Clearly I messed it up.
The patch also computes and shows the counts for old entries and new entries separately. Though not useful for now, but in incremental workflow it may be helpful to distinguish between the old and new entries.

24+36 should have the fix, so -XX:+AOTClassLinking should be enabled for 
you. You can check for this log to confirm:

[0.022s][info][cds] Using AOT-linked classes: true (static archive: has 
aot-linked classes)

That message is a bit cryptic. Basically "--module-path dir" gets 
translated to "-Djdk.module.path=dir" by the Java launcher. Because of 
that, the archived module graph in the default CDS archive cannot be 
used. This is normal in your use case.

Did you create /Users/headius/work/jruby/lib/jruby.jsa with "java 
-Xshare:dump" or "java -XX:AOTMode=create"? If so, it will be recognized 
as a "static archive".

I created https://bugs.openjdk.org/browse/JDK-8350057 to address this issue.

If you want to work around this bug, you can check the magic number of 
the file:

https://github.com/openjdk/jdk/blob/ff52859d2ad65b97c56dd19323213a0d07be47ae/src/hotspot/share/include/cds.h#L39-L40

#define CDS_ARCHIVE_MAGIC 0xf00baba2
#define CDS_DYNAMIC_ARCHIVE_MAGIC 0xf00baba8

If the magic number is not 0xf00baba8, you can delete the file before 
running with "java -XX:+AutoCreateSharedArchive -XX:SharedArchiveFile=..."

Profiles show that various `name_and_sig_as_C_string` are taking about 1.2% in Leyden benchmark profiles. We should sweep those up into conditional log statements and/or common the paths where we actually need these names outside of logging. 

After this fix, the profile impact of `name_and_sig_as_C_string` is `<0.05%`.

This looks good. I ran all the CDS tests and found only one crash with SpringClinic due to [JDK-8350148](https://bugs.openjdk.org/browse/JDK-8350148). I will try to fix this bug first before this PR is integrated.

src/hotspot/share/cds/metaspaceShared.cpp line 1025:

> 1024:       // Now that we don't make a side table, is this needed for the remaining call

I think comments from 1022-1023 can be removed. The assert should be moved to just after line 1006:

I pushed a fix for [JDK-8350148](https://bugs.openjdk.org/browse/JDK-8350148) into the premain branch. I test this PR on top and all Leyden tests passed.

This left brace does not follow the code style in this file. Either remove this pair of brace or make it `if (mt != null) {`

src/java.base/share/classes/java/lang/invoke/MethodTypeForm.java line 134:

> 132:     @SuppressWarnings({"rawtypes", "unchecked"})

I recommend restoring the static types of the arrays to `SoftReference<MethodHandle>[]` unless there is extra overhead from loading/initialization of `SoftReference` class.

I tried this before but then 'this.methodHandles = new SoftReference<MethodHandle>[MH_LIMIT];' is not allowed due to the error 'generic array creation'.  I looked at allocating using ArrayList<>(initialCapacity) as they are backed. with Object[], but then we have to add range checks on the reads to avoid IndexOutOfBounds or set a null entry at (initialCapacity-1); unless someone can suggest a better implementation I'm inclined to let it stand

You can try like `(SoftReference<MethodHandle>[]) new SoftReference<?>[MH_LIMIT]`, and add `@SuppressWarnings("unchecked")` on the constructors.

Is this a new requirement, or did I perform a bad git operation somehow?  I didn't have a problem with my last PR

Mat Carter has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains six additional commits since the last revision:

 - Merge branch 'premain' into macarte-weakrefs
 - Fix style issue
 - Addressing PR feedback - moving assert higher
 - Fix missing line at end of file
 - Remove superfluous SuppressWarnings now we've removed unchecked casts
 - Remove workarounds now that References are supported in CDS

This is a github display; don't worry about it. We do not use GitHub merge here. The openjdk skara bots are responsible for squash-committing the PR once you type the `/integrate` command when it is ready.

@macarte I think you can try restoring all these touched by JEP 483 to the prior version. I can see that there are a few changes in MethodTypeForm.java that you haven't restored yet

https://github.com/openjdk/jdk/commit/41a2d49f0a1ed298b8ab023ce634335464454fe7#diff-26f13a6a296ac624577fb32626de70ed7c56b1a1c80fde258aea71a25b7560e2

- LamdaFormEditor.java
- MethoHandleNatives.java
- MethodType.java
- MethodTypeForm.java

That should get rid of the compilation error you mentioned above.

I have pushed another change that refactors the way stats are collected and do it in a more organized way rather than in a ad-hoc manner. I have separated the stats into two categories - stats for the code as stored in the AOT Cache, and stats reflecting runtime characteristic of the code.
Note that it does not change the stats that are printed on `-Xlog:init`, but it gives a slightly better breakdown on exit (`-Xlog:scc+exit`) with stats for each compilation tier. So now on exit it shows following:


[7.544s][info   ][scc,exit] Wrote 2209 SCCEntry entries(181748 max size) to AOT Code Cache
[7.544s][info   ][scc,exit]   Adapter: total=545(old=0+new=545)
[7.544s][info   ][scc,exit]   Stub: total=3(old=0+new=3)

Nice.

Looks like you have tabs instead of spaces in few places.

Looks good to me. Just a small nit.
I ran the Leyden test cases in our CI and didn't see any regressions.

src/java.base/share/classes/java/lang/invoke/MethodTypeForm.java line 147:

Unintentional whitespace change.

There are interesting use cases where we want the AOT-only mode. We can emulate this in current Leyden prototype by relying on preload code, and stopping any profiling, which would naturally lead to no JIT compilations. This would also make interpreter code a bit faster in case we need to fall back there. This mode looks also helpful for studying the compiler dynamics.

Additional testing:
 - [x] Eyeballing compilation logs with `-XX:+PreloadOnly`
 - [ ] Linux x86_64 server fastdebug, `runtime/cds`
 - [ ] Linux x86_64 server fastdebug, `runtime/cds` with `-XX:+PreloadOnly`

In both cases, "user" time goes down because we have no additional code load / JIT compilations. In 32-core case, we can see that peak performance suffers a bit, since preload code is not 100% efficient. The combination of these two factors is a net benefit in 2-core case: not doing JIT compilations more than pays for preload code inefficiency. This tradeoff of course depends on how well-trained the scenario is.

> There are interesting use cases where we want the AOT-only mode. We can emulate this in current Leyden prototype by relying on preload code, and stopping any profiling, which would naturally lead to no JIT compilations. This would also make interpreter code a bit faster in case we need to fall back there. This mode looks also helpful for studying the compiler dynamics.

Plus, preload code needs to be a bit more resilient to invalidations, which would improve the perf gap here: https://github.com/openjdk/leyden/pull/38. With that POC patch applied, the peak performance gap shortens considerably:

Yes, good ideas, done so.

Yeah. I added logging at `GraphKit::uncommon_trap`. That logging is super-noisy. So I left the tracing code that warns when we trigger the actual deopt by stepping on such trap.

Yes, that would a good next step if we find this thing useful.

Proposed solution looks to me way too specific and niche. 

Instead, I'd prefer to see a way to combine different JIT-compilation modes (`-XX:TieredStopAtLevel=01234`) with ability to limit usage of AOTed code (e.g., `-XX:DisableAOTCodeLevels=P124`).  `PreloadOnly` is equivalent to `-XX:TieredStopAtLevel=0` and `-XX:DisableAOTCodeLevels=124`.

Looks good.

src/hotspot/share/runtime/deoptimization.cpp line 2134:

> 2132:         // Compiler logs all uncommon traps with -Xlog:scc. That log is noisy, and some traps may be

Does it warrant a warning though? It can become quite noisy and users don't have any way to address the problem. `log_info`    looks a better fit here (and, probably, narrow the category to `scc+deoptimization`).

Doing these as `warnings` are my habit when doing high-perf prototypes. But yeah, we can do `info` instead, and I'll just enable the logging in my perf scripts.

@iklam How soon can this be upstreamed? I think I might be working on MH recently and I hope we can simplify the cache and avoid conflicts down the road by a quick upstream to mainline JDK.

I can create the PR for mainline, we'll need a JBS Item.  

One question though: this commit has no flags to disable adding WeakReferences to the cache, is this okay for tip or should we add a flag?

Yes, please create a new JBS issue, as the JDK-8341587 was targeted to the Leyden repo and is already marked as closed.

> One question though: this commit has no flags to disable adding WeakReferences to the cache, is this okay for tip or should we add a flag?

It would be too difficult to implement a switch to disable WeakReferences. To do that we would need to keep the side table and then dynamically choose between the two behaviors.

In the long run, our goal is to be able to store complex data structures used by the JDK library (and even applications). It's quite common to have WeakReferences in such data structures, and we don't want to require the Java code to be modified before such data structures can be stored.

BTW I think we still have a problem -- in the assembly phase, the ReferenceQueue may contain WeakReferences that are used by data structures that we don't intend to store in the AOT cache, but they may be discovered by heapShared.cpp and end up in the AOT cache. 

So @liach we may not be able to upstream this into the mainline yet.

With a simple test, it seems like we are archiving only WeakReferences used by MethodTypes, etc. I don't see anything that we don't want, so that's so far so good:


# Must use JDK from leyden/premain repo
$ java -cp HelloWorld.jar -XX:AOTMode=record -XX:AOTConfiguration=hw.aotconfig HelloWorld
$ java -Xlog:cds+map=trace,cds+map+oops=trace:file=cds.oops.txt:none:filesize=0 -cp HelloWorld.jar -XX:AOTMode=create -Xlog:cds -XX:AOTCache=hw.aot -XX:AOTConfiguration=hw.aotconfig
$ grep -n private.*referent cds.oops.txt

The WeakReferenceKey look like this:


0x00000007ff868bf0: @@ Object (0xfff0d17e) jdk.internal.util.WeakReferenceKey
 - klass: 'jdk/internal/util/WeakReferenceKey' 0x0000000800293578

It's queue look like this (0 items!)


0x00000007ff866988: @@ Object (0xfff0cd31) java.lang.ref.ReferenceQueue

 - private final 'lock' 'Ljava/lang/ref/ReferenceQueue$Lock;' @24 0x00000007ff8d8aa0 (0xfff1b154) java.lang.ref.ReferenceQueue$Lock


And all the `WeakReferenceKey::next` fields are null. I wonder why.


$ grep "volatile 'next'.*Reference" cds.oops.txt | wc
    114     684    6384
$ grep "volatile 'next'.*Reference" cds.oops.txt | grep -v null | wc
      0       0       0


So I think we need to understand this a little more before moving forward with upstreaming to mainline.

Thanks for this evaluation. I will just be careful when working with the cache area of Method Handles.
