Questions about the Hermetic Java project
by Magnus Ihse Bursie 09 Jun '25

09 Jun '25

First some background for build-dev: I have spent some time looking at the build implications of the Hermetic Java effort, which is part of Project Leyden. A high-level overview is available here: https://cr.openjdk.org/~jiangli/hermetic_java.pdf and the current source code is here: https://github.com/openjdk/leyden/tree/hermetic-java-runtime. Hermetic Java faces several challenges, but the part that is relevant for the build system is the ability to create static libraries. We've had this functionality (in three different ways...) for some time, but it is rather badly implemented. As a result of my investigations, I have a bunch of questions. :-) I have gotten some answers in private discussion, but for the sake of transparency I will repeat them here, to foster an open dialogue. 1. Am I correct in understanding that the ultimate goal of this exercise is to be able to have jmods which include static libraries (*.a) of the native code which the module uses, and that the user can then run a special jlink command to have this linked into a single executable binary (which also bundles the *.class files and any additional resources needed)? 2. If so, is the idea to create special kinds of static jmods, like java.base-static.jmod, that contains *.a files instead of lib*.so files? Or is the idea that the normal jmod should contain both? 3. Linking .o and .a files into an executable is a formidable task. Is the intention to have jlink call a system-provided ld, or to bundle ld with jlink, or to reimplement this functionality in Java? 4. Is the intention is to allow users to create their own jmods with static libraries, and have these linked in as well? This seems to be the case. If that is so, then there will always be the risk for name collisions, and we can only minimize the risk by making sure any global names are as unique as possible. 5. The original implementation of static builds in the JDK, created for the Mobile project, used a configure flag, --enable-static-builds, to change the entire behavior of the build system to only produce *.a files instead of lib*.so. In contrast, the current system is using a special target instead. In my eyes, this is a much worse solution. Apart from the conceptual principle (if the build should generate static or dynamic libraries is definitely a property of what a "configuration" means), this makes it much harder to implement efficiently, since we cannot make changes in NativeCompilation.gmk, where they are needed. That was not as much a question as a statement. 🙂 But here is the question: Do you think it would be reasonable to restore the old behavior but with the new methods, so that we don't use special targets, but instead tells configure to generate static libraries? I'm thinking we should have a flag like "--with-library-type=" that can have values "dynamic" (which is default), "static" or "both". I am not sure if "both" are needed, but if we want to bundle both lib*.so and *.a files into a single jmod file (see question 2 above), then it definitely is. In general, the cost of producing two kinds of libraries are quite small, compared to the cost of compiling the source code to object files. Finally, I have looked at how to manipulate symbol visibility. There seems many ways forward, so I feel confident that we can find a good solution. One way forward is to use objcopy to manipulate symbol status (global/local). There is an option --localize-symbol in objcopy, that has been available in objcopy since at least 2.15, which was released 2004, so it should be safe to use. But ideally we should avoid using objcopy and do this as part of the linking process. This should be possible to do, given that we make changes in NativeCompilation.gmk -- see question 5 above. As a fallback, it is also possible to rename symbols, either piecewise or wholesale, using objcopy. There are many ways to do this, using --prefix-symbols, --redefine-sym or --redefine-syms (note the -s, this takes a file with a list of symbols). Thus we can always introduce a "post factum namespace" by renaming symbols. So in the end, I think it will be fully possible to produce .a files that only has global symbols for the functions that are part of the API exposed by that library, and have all other symbols local, and make this is in a way that is consistent with the rest of the build system. Finally, a note on Hotspot. Due to debugging reasons, we export basically all symbols in hotspot as global. This is not reasonable to do for a static build. The effect of not exporting those symbols will be that SA will not function to 100%. On the other hand, I have no idea if SA works at all with a static build. Have you tested this? Is this part of the plan to support, or will it be officially dropped for Hermetic Java? /Magnus

RFR: Save/load i2c2i adapters
by Ashutosh Mehra 05 Feb '25

05 Feb '25

This is an attempt to save and load i2c2i adapters along with the adapter handler table. There are mainly two parts to this change: 1. Storing of adapter code in the SCCache or AOT code cache. 2. Storing of adapter handler table in the AOT cache. Adapter handler table is a map from AdapterFingerPrint to AdapterHnadlerEntry. To store them in AOT cache, AdapterFingerPrint and AdapterHandlerEntry are updated to MetaspaceObj. Both these entities are discovered and added to the cache while processing the Method. When storing the adapter handler table, only the entries that have already been archived are considered. This allows pruning of AdapterHnadlerEntry that may be only reachable through a Method that is not eligible to be archived. An AdapterHandlerEntry has pointer to the adapter code. Because the AdapterHandlerEntry and the adapter code are stored in separate archives, this link between the AdapterHandlerEntry and the adapter code needs to be removed (see AdapterHandlerEntry::remove_unshareable_info()). During the production run, as the methods in the AOT cache are adopted, the AdapterHandlerEntry is linked back to the adapter code (see AdapterHandlerEntry::restore_unshareable_info). All this code is guarded by -XX:[+-]ArchiveAdapters option which defaults to false, but is set to true in CDSConfig during the assembly phase. Other changes worth mentioning: 1. Changes to the SCCache infrastructure to make it possible to store and load adapter code. (Thanks to @adinn) 2. Updating AdapterFingerPrint hashing algorithm to avoid collisions. If there is any collision, then it will prevent finding the adapter code in the SCCache. (Again courtesy of @adinn) Thanks to @adinn for providing many of these changes. Performance: -Xlog:init shows time taken for linking of Methods and making adapters. An example output is: ClassLoader: clinit: 150us / 4612 events link methods: 28980us / 176893 events method adapters: 15378us / 697 events Save/load of adapters seem to have improved these stats. | Quarkus | -ArchiveAdapters | +ArchiveAdapters | |---|---|---| | link methods | 12214us / 58913 events | 2700us / 58913 events | | method adapters | 7793us / 607 events | 4402us / 38 events | | Spring-petclinic | -ArchiveAdapters | +ArchiveAdapters | |---|---|---| | link methods | 28980us / 176893 events | 7485us / 176893 events | | method adapters | 15378us / 697 events | 7050us / 13 events | However, testing with Quarkus app, I don't see any noticeable improvement in the startup time. ------------- Commit messages: - More whitespace fixes - Move the check for is_abstract_method_adapter() to correct place - Surround code with INCLUDE_CDS where appropriate - Fix whitespace issues - Fix compile failures - Fix a bug and add comment in AdapterHandlerEntry::restore_unshareable_info() - Refactor code to avoid calling AdapterFingerPrint::as_basic_type() when - Add a helper method to iterate over AdapterFingerPrint - Improve hashing algorithm for AdapterFingerPrint - Misc changes - ... and 10 more: https://git.openjdk.org/leyden/compare/a1672ea6...04fb256b Changes: https://git.openjdk.org/leyden/pull/25/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=25&range=00 Stats: 1293 lines in 25 files changed: 834 ins; 248 del; 211 mod Patch: https://git.openjdk.org/leyden/pull/25.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/25/head:pull/25 PR: https://git.openjdk.org/leyden/pull/25

RFR: 8348960: [leyden] compiler/c1/TestConcurrentPatching.java is stuck
by Aleksey Shipilev 04 Feb '25

04 Feb '25

This is seen in GHA, and reproduces well on my machine as well: $ CONF=linux-x86_64-server-fastdebug make images test TEST=compiler/c1/TestConcurrentPatching.java <stuck, timeout> Test runs with `-Xcomp`. gdb "thread apply all bt" shows the compilers are idle. Supplying `-XX:-UseLockFreeCompileQueues` makes the test pass. I believe there is a bug in `UseLockFreeCompileQueues` in leyden repo. The comment hopefully explains what happens here. This is a corner case that seems to reproduce on the test that runs `-Xcomp` with a very few compilations.

Sketched breakdown of task for implementing code save/restore in Leyden repo and mainline
by Andrew Dinn 01 Feb '25

01 Feb '25

Hi all, Following up on our discussion in yesterday's meeting I have sketched below a list of the various tasks we need to perform to implement code save/restore, both immediately with the hope of getting them into jdk25 and in the longer term. The list includes some things it would be preferable to prototype in the Leyden premain branch before transferring to mainline, other migration tasks that serve to transfer existing protptype code from premain to mainline and more speculative tasks that are unlikely to be achievable for jdk25. Please review and feel free to offer additions and corrections -- I am not at all sure I have it all down and/or correct. n.b. one general note that applies to all migration or direct, mainline implementation tasks is that we need to consider how we handle CPUs other than aarch64/x86_64 and OSes other than Linux. Even if we leave AOT code cache functionality 'unimplemented' for other ports we will still need to ensure that the code we migrate will successfully allow for missing ('not yet available') implementations. When performing the migration tasks we may well want/need to pull in devs from those other ports to, at least, help achieve that minimum goal or, perhaps, implement some subset of the relevant functionality. regards, Andrew Dinn ----------- Leyden repo preliminaries: -------------------------- Modify SCCache implementation to save/restore code in the AOT cache file with metadata, heap data etc. Complete save/restore of i2c2i adapters and associated index Complete direct install of mapped AOT adapter code into CodeCache Complete direct install of nmethod code into CodeCache Rework save/restore of runtime, c1, opto and stubgen blobs & stubs after merge of mainline stub cleanup Implement save/restore of other demand-generated linkage stubs (i/vtable adapters, method handle adapters, ICCache, ???) Migration steps: ---------------- Migrate SCCache support to save/restore i2c2i adapters and associated lookup tables and relink methods with correct adapters Incrementally extend SCCache to support save/restore of other demand-geerated adapters and associated lookup tables Implement save/restore of runtime, c1, opto and stubgen blobs & stubs Implement save/restore of special case nmethods and associated index info (i.e. compiled MethodHandle adapter nmethods associated with Java MethodTypes and associated Java lookup table -- any others) Implement save/restore of general nmethods Implement prelinking of nmethod -> nmethod call sites Implement prelinking of nmethod -> stub call sites More speculative improvements: ------------------------------ (do we prototype these in premain before migrating?) Adjust code generation to store runtime addresses in nmethod constant section and use pc-relative loads (minimizing relocs) -- requires new relocs for gloal addresses and/or extending CDS link patching to include extra 'code address' pass. Investigate further use of 'code cache' global constant section instead of per nmethod constant sections. Investigate use of compressed nmethod 'debug info' to minimize size of AOT cache (n.b. best to use it compressed in mainline with or without AOT so save/restore gets it for free)

RFR: 8348858: [leyden] Bump the default code buffer sizes to store more generated code
by Aleksey Shipilev 31 Jan '25

31 Jan '25

Due to current prototype limitation, we cannot yet store the generated code that has the expanded code buffer. I tried to address that directly, but I think relocations disagree with the whole thing, so this implementation limitation stays for a bit longer. I turned the bailout due to that cause from `info` into `warning`. On `JavacBenchApp 50`, this causes us to lose 700 (!) C2 compiled methods from the SCC! We can dodge significant part of the hit by bumping the default code buffer sizes, and thus making buffers less likely to require resizing, and thus allowing to store more code in SCC. Also needs [JDK-8348855](https://bugs.openjdk.org/browse/JDK-8348855) from mainline to work well with G1. Current PR includes it, and I will upstream it separately first. Additional testing: - [x] Linux x86_64 server fastdebug, `runtime/cds` ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/28/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=28&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8348858 Stats: 28 lines in 5 files changed: 25 ins; 0 del; 3 mod Patch: https://git.openjdk.org/leyden/pull/28.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/28/head:pull/28 PR: https://git.openjdk.org/leyden/pull/28

RFR: 8348957: [leyden] Excess PrintCompilation printing on compile task start
by Aleksey Shipilev 29 Jan '25

29 Jan '25

This bothers me a bit in current -XX:+PrintCompilation logs. For various reasons, we have the `DirectiveSet` for every method, which initialized `PrintCompilationOption = true` when `-XX:+PrintCompilation` is set, which prints the compile task at the task start. We don't need that printout, we only really care about the printout at the end of the compilation. Before: $ grep com.sun.tools.javac.comp.Resolve::notOverriddenIn out 105 W0.0 646 AP 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) 105 W0.0 Q52.2 C0.1 646 AP 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) 252 W0.1 3745 A 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) 252 646 AP 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) made not entrant 252 W0.1 Q0.0 C0.1 3745 A 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) After: 88 W0.0 Q31.3 C0.2 696 AP 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) 239 696 AP 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) made not entrant 239 W0.1 Q0.0 C0.1 3809 A 4 com.sun.tools.javac.comp.Resolve::notOverriddenIn (124 bytes) I'll also look into upstreaming the extended compile task logging, since it is useful to study compilation dynamics outside of Leyden as well. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/29/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=29&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8348957 Stats: 6 lines in 1 file changed: 1 ins; 4 del; 1 mod Patch: https://git.openjdk.org/leyden/pull/29.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/29/head:pull/29 PR: https://git.openjdk.org/leyden/pull/29
