Message-ID: <epzPa90i2MZ6nw8aFslc4ff3toN_Cs59DXGzZx-e32c=.227c80bc-157a-4cbd-acd0-2bb4f08ea2a2@github.com>

Updates made in commits [1][2][3][4] are missing for PPC64, S390, ARM32
and Zero, leading to build failures.

Even though we mainly focus on x64 and AArch64 platforms currently, I
think it would be nice if the builds on other platforms are not broken.

Hence, we apply the similar updates from [1][2][3][4] to PPC64, S390,
ARM32 and Zero in this patch.

Testing:

Linux PPC64 cross-compilation
Linux S390 cross-compilation
Linux ARM32 cross-compilation
Linux AArch64 Zero (Hotspot) compilation
Linux x86_64 tier1_loom passes
Linux AArch64 tier1_loom passes

GHA test results can be found in https://github.com/shqking/loom/actions/runs/1913619403
As noted there, `PPC64/S390/ARM32/Zero` builds passed as expected.

Thanks for the update. It's good to keep these ports building, even with Unimplemented stubs. Ron, are you okay if we integrate this?

I wasn't able to reproduce this, but from looking at the core dump, not trying to emit more instructions when the code cache is full should definitely help.

Thanks for this. I've seen this issue several times, always aarch64 with the stack trace in bug report. I don't maintain this area but moving the post_call_nop to after checking "call" looks right to me.

Subject: RFR: Better jdb support for vthreads. Improved jdb vthread testing
 support.
Message-ID: <pBUyiLjwcNNVTOtW2A-e1rui561IoDicAIfUo2p2DQo=.972ebc9b-3857-496b-8157-d05f30c50b83@github.com>

This PR contains a set of some what disparate but related set of changes to JDB, JDI, and nsk jdb tests and test support (Jdb.java).

jdb: Made the ?kill? command support `ThreadReference.stop()` throwing `IllegalThreadStateException` for vthreads, because this is how `ThreadReference.stop()` is now spec?d. This change is in `Commands.java`. The rest of the changes are just cleanup. One of the changes in the `kill001` test is to test for this (see below)

jdb: Use `PlatformThreadOnlyFilters` to prevent `ThreadStart/Death` event for vthreads. Instead detect vthreads when events are received on them. The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.

jdb: Add `-trackallvthreads` option. This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were. The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.

jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.

`nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:

`   (nsk.jdb.kill.kill001.MyThread)693            Thread-0            waiting in a monitor`

Now it contains:

`   (java.lang.Thread)693                         MyThread-0          waiting in a monitor`

So instead of searching for ?(MyThread)? and grabbing the threadId that comes right after it, `getThreadIdsByName()` first finds all the lines of output that contain ?nsk.jdb.kill.kill001.MyThread?, and then for those lines only gets the threadID that is right after ?(java.lang.Thread)? or ?(java.lang.VirtualThread)?.

jdb `kill001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. Use new `getThreadIdsByName()` support instead of `getThreadIds()`. Allow/expect the `kill` command to fail with "Illegal thread state? when in vthread mode.

jdb `threads002` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. I forget why I decided to convert this test. Seems it was useful for testing something I was working on for this PR, but I can?t recall. Maybe it was so I could clone it for the new `threads003` test below.

jdb `trace001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. This is a test I had converted long ago when I first experimented with the `getThreadIdsByName()` support, so I included it with this PR.

jdb `threads003` test: This is a new thread test that tests jdb?s ability to learn about a thread when an event arrives on it. It creates 5 threads, two of which receive a breakpoint. It looks at the `threads` output and checks that only those two vthreads are present. I also used this test to help confirm that the `ThreadDeath` events are only received for these two vthreads. This was done manually by looking for the ?TDR removed? output generated by `EventHandler.threadDeathEvent()`. I didn?t put this into the test itself since that println is just for debugging and is now commented out.

Marked as reviewed by rpressler (Lead).

I don't have the cycles to review changes to ports other than x64 and aarch64, so I just approved all changes to non-shared files in these ports.

The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.

This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were. The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.
> 
> jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.

> `nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:

I skimmed through the change the jdb and they look okay. We'll just need to remember that there is a new option for jdb that will need to be tracked by the eventual CSR.

src/jdk.jdi/share/classes/com/sun/tools/example/debug/tty/EventHandler.java line 125:

> 123:                 tdr.addThreadFilter(eventThread);

> 125:                 //System.out.println("TDR added: " + thread);

Left over trace message.

src/jdk.jdi/share/classes/com/sun/tools/example/debug/tty/EventHandler.java line 306:

> 304:             EventRequestManager erm = Env.vm().eventRequestManager();
> 305:             erm.deleteEventRequest(event.request());
> 306:             //System.out.println("TDR removed: " + thread);

Another one

src/jdk.jdi/share/classes/com/sun/tools/example/debug/tty/TTY.java line 77:

> 75:     private volatile boolean shuttingDown = false;
> 76: 
> 77:     private static boolean trackAllVthreads = false;

Probably best to move it to the other static fields. Also not need to explicitly initialise it to false. For shuttingDown (not changed here) then you avoid volatile-write by not explicitly initializing it.

src/jdk.jdi/share/classes/com/sun/tools/example/debug/tty/TTY.java line 977:

> 975:                     }
> 976:                 }
> 977:             } else if (token.equals("-trackallvthreads")) {

So `jdb -tracevthreads`. We'll need to remember this change for the eventual CSR.

Yes, I plan on removing these. They were useful for making sure it was working properly.

I think you  meant `-trackallvthreads`. Do we have a CSR in place yet that I can add too?

Not for the loom repo but we will include need to remember to include it in the eventual CSR when we bring the feature into main line.

I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.

The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:

It is not clear why a virtual thread is expected here.
At least, some comment would be nice to have.

I looked at the jdb changes. They look good to me. I've posed one comment though.

Yeah, that got misplaced, probably when I shuffled around some code. I think it would be correct if it was moved below the `addThread()` call and was changed to:

`            assert !(added && !eventThread.isVirtual());`

which is probably more easily read as:

`            assert !added || eventThread.isVirtual());`

First I need to see if I can even get asserts enabled since that one should have been triggered.

Actually that's not quite right either. It looks like it needs to be:


            if (added) {
                assert eventThread.isVirtual();
            }

If this thread was added, it must be an a virtual thread, because if it was not it would have been previously added by a ThreadStart event.

The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.

> jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.

> `nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:
> 
> `   (nsk.jdb.kill.kill001.MyThread)693            Thread-0            waiting in a monitor`

> 
> jdb: Use `PlatformThreadOnlyFilters` to prevent `ThreadStart/Death` event for vthreads. Instead detect vthreads when events are received on them. The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.
> 
> jdb: Add `-trackallvthreads` option. This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were.

It is better to add a comment explaining this.
Otherwise, it is hard to understand why this conclusion was made.
Also, why do you think this is not equal to your conditional assert above?:
   assert !added || eventThread.isVirtual());

I added some comments.

Actually that does work, but I think it is easier to read with the "if" statement.

Suggestion:

        if (event instanceof ClassPrepareEvent evt) {
            eventThread = evt.thread();

The same for lines 109-110

please add -verbose at separate line.
And I suppose you changed waittime temporary and forgot to revert it.
The same for other tests

if and for at the same line don't look good

Ok, will move to separate line. For `-waittime`, 5 seems overkill for all these tests. If anything ever goes wrong with the test, it seems you always end up waiting for a timeout. So first thing I do is change `-waittime` to 1 so I don't have to wait as long when debugging the test. I'd change it to .5 if I could, but it doesn't accept decimals. I could change it back to 5, but I don't see why it needs to be so big. Maybe @lmesnik can comment on this.

Seems it was useful for testing something I was working on for this PR, but I can?t recall. Maybe it was so I could clone it for the new `threads003` test below.

> 
> jdb `threads003` test: This is a new thread test that tests jdb?s ability to learn about a thread when an event arrives on it. It creates 5 threads, two of which receive a breakpoint. It looks at the `threads` output and checks that only those two vthreads are present. I also used this test to help confirm that the `ThreadDeath` events are only received for these two vthreads. This was done manually by looking for the ?TDR removed? output generated by `EventHandler.threadDeathEvent()`. I didn?t put this into the test itself since that println is just for debugging and is now commented out.

In commit 4d2710[1], one invocation of function print_frames() is moved
from condition `!PRODUCT` to condition `ASSERT`. As a result, all the
usages are now under condition `ASSERT`, leading to the compilation
warning "unused-function" in optimized VM build.

Hence, in this patch, we move the defintion of function print_frames()
to condition `ASSERT`.

As shown in https://github.com/shqking/loom/runs/5475434690?check_suite_focus=true, optimized build can pass with this patch.

This change is in `Commands.java`. The rest of the changes are just cleanup. One of the changes in the `kill001` test is to test for this (see below)
>> 
>> jdb: Use `PlatformThreadOnlyFilters` to prevent `ThreadStart/Death` event for vthreads. Instead detect vthreads when events are received on them. The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.
>> 
>> jdb: Add `-trackallvthreads` option. This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were. The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.
>> 
>> jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.
>> 
>> `nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:
>> 
>> `   (nsk.jdb.kill.kill001.MyThread)693            Thread-0            waiting in a monitor`
>> 
>> Now it contains:
>> 
>> `   (java.lang.Thread)693                         MyThread-0          waiting in a monitor`
>> 
>> So instead of searching for ?(MyThread)? and grabbing the threadId that comes right after it, `getThreadIdsByName()` first finds all the lines of output that contain ?nsk.jdb.kill.kill001.MyThread?, and then for those lines only gets the threadID that is right after ?(java.lang.Thread)? or ?(java.lang.VirtualThread)?.
>> 
>> jdb `kill001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. Use new `getThreadIdsByName()` support instead of `getThreadIds()`. Allow/expect the `kill` command to fail with "Illegal thread state? when in vthread mode.
>> 
>> jdb `threads002` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. I forget why I decided to convert this test. Seems it was useful for testing something I was working on for this PR, but I can?t recall. Maybe it was so I could clone it for the new `threads003` test below.
>> 
>> jdb `trace001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. This is a test I had converted long ago when I first experimented with the `getThreadIdsByName()` support, so I included it with this PR.
>> 
>> jdb `threads003` test: This is a new thread test that tests jdb?s ability to learn about a thread when an event arrives on it. It creates 5 threads, two of which receive a breakpoint. It looks at the `threads` output and checks that only those two vthreads are present. I also used this test to help confirm that the `ThreadDeath` events are only received for these two vthreads. This was done manually by looking for the ?TDR removed? output generated by `EventHandler.threadDeathEvent()`. I didn?t put this into the test itself since that println is just for debugging and is now commented out.

This fix removes collect_for_codecache(), and uses collect() directly instead. This has the advantage that the g1 code path can be run concurrently using a concurrent mark instead of a full gc.

Changes requested by tschatzl (no project role).

src/hotspot/share/gc/g1/g1FullCollector.cpp line 198:

Please add a helper method for this copy&paste in `G1CollectedHeap`. Something like `start_codecache_marking_cycle_if_inactive` (not perfect) or similar.

It takes almost double the time to compile HotSpot in the Loom repository compared to the mainline. One source of this regression is the include of the *CollectedHeap.inline.hpp files in the *BarrierSet.inline.hpp files, needed to inline the requires_barriers call all the way down to the GC implementations. 

This patch removes the inlining and calls the virtual calls instead. This recuperate most of the lost compilation speed, but not quite all (still about a 20% regression). I've verified with a small micro that this doesn't increase the freeze/thaw times. In fact, it increased the performance slightly. Comparing the generated code, I see that the inlined code had two branches and made a jump to the fast path (and not the expected slow path). With the non-inlined call there's only one branch and the fast-path is right after the check.

The two patches on top of the fix just removes infrastructure that isn't needed when this has been removed.

(Minimal version of PR #104)

It takes almost double the time to compile HotSpot in the Loom repository compared to the mainline. One source of this regression is the include of the *CollectedHeap.inline.hpp files in the *BarrierSet.inline.hpp files, needed to inline the requires_barriers call all the way down to the GC implementations.

Subject: RFR: Note frames that are on the heap, rather than addressing mode
Message-ID: <l977XKRR22t7LWXLityw0eAU2ZukA3mYHgyCzIt1ad4=.d617444f-1f35-40ab-8e00-75c6aa365da5@github.com>

... for interpreted frames.
This changes "addressing mode" to a boolean whether the frame is on the heap instead.  The compiler frames don't have code that uses the relative offsets but the frames can be marked as on-heap anyway.
There's one place that I passed false, not sure if that's right.
Not urgent to code review.
Tested with: alias loomjprt='mach5 --patch-based --extra-src-dirs /scratch/cphillim/hg/jdk-loom -j loom-tier1,loom-tier2,loom-tier3'

One source of this regression is the include of the *CollectedHeap.inline.hpp files in the *BarrierSet.inline.hpp files, needed to inline the requires_barriers call all the way down to the GC implementations.

I've verified with a small micro that this doesn't increase the freeze/thaw times. In fact, it increased the performance slightly. Comparing the generated code, I see that the inlined code had two branches and made a jump to the fast path (and not the expected slow path). With the non-inlined call there's only one branch and the fast-path is right after the check.

> This PR contains a set of some what disparate but related set of changes to JDB, JDI, and nsk jdb tests and test support (Jdb.java).
> 
> jdb: Made the ?kill? command support `ThreadReference.stop()` throwing `IllegalThreadStateException` for vthreads, because this is how `ThreadReference.stop()` is now spec?d. This change is in `Commands.java`. The rest of the changes are just cleanup. One of the changes in the `kill001` test is to test for this (see below)
> 
> jdb: Use `PlatformThreadOnlyFilters` to prevent `ThreadStart/Death` event for vthreads. Instead detect vthreads when events are received on them. The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.
> 
> jdb: Add `-trackallvthreads` option. This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were. The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.
> 
> jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.
> 
> `nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:
> 
> `   (nsk.jdb.kill.kill001.MyThread)693            Thread-0            waiting in a monitor`
> 
> Now it contains:
> 
> `   (java.lang.Thread)693                         MyThread-0          waiting in a monitor`
> 
> So instead of searching for ?(MyThread)? and grabbing the threadId that comes right after it, `getThreadIdsByName()` first finds all the lines of output that contain ?nsk.jdb.kill.kill001.MyThread?, and then for those lines only gets the threadID that is right after ?(java.lang.Thread)? or ?(java.lang.VirtualThread)?.
> 
> jdb `kill001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. Use new `getThreadIdsByName()` support instead of `getThreadIds()`. Allow/expect the `kill` command to fail with "Illegal thread state? when in vthread mode.
> 
> jdb `threads002` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. I forget why I decided to convert this test. Seems it was useful for testing something I was working on for this PR, but I can?t recall. Maybe it was so I could clone it for the new `threads003` test below.
> 
> jdb `trace001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. This is a test I had converted long ago when I first experimented with the `getThreadIdsByName()` support, so I included it with this PR.
> 
> jdb `threads003` test: This is a new thread test that tests jdb?s ability to learn about a thread when an event arrives on it. It creates 5 threads, two of which receive a breakpoint. It looks at the `threads` output and checks that only those two vthreads are present. I also used this test to help confirm that the `ThreadDeath` events are only received for these two vthreads. This was done manually by looking for the ?TDR removed? output generated by `EventHandler.threadDeathEvent()`. I didn?t put this into the test itself since that println is just for debugging and is now commented out.

Chris Plummer has updated the pull request incrementally with four additional commits since the last revision:

 - Rename trackallvthreads to trackvthreads.
 - use implements Runnable instead of extends Thread.
 - Use waittime=5 intead of 1 like the other tests do.
 - Rename trackallvthreads to trackvthreads.

Thank you! this was one of the things I wanted most. I was reviewing the stackChunkFrameStream separation patch.

Good.

This change is in `Commands.java`. The rest of the changes are just cleanup. One of the changes in the `kill001` test is to test for this (see below)

The goal here is to prevent jdb from getting a flood of `ThreadStart/Death` events, and getting bogged down with them. With the `PlatformThreadOnlyFilters` in place, this means jdb is not notified when a vthread dies, even one that it learned about later when an event came in on it. For these each of these ?learned? vthreads a separate `ThreadDeathRequest` is needed that uses the thread itself as a `ThreadFilter`. This way jdb can tell when these vthreads die. This part is handled in `EventHandler.java`. `VMConnection.java` is where `PlatformThreadOnlyFilters` are added.
> 
> jdb: Add `-trackallvthreads` option. This prevents the use of the `PlatformThreadsOnlyFilters` described above, and instead relies on jdb getting the initial set of vthreads from the debug agent via `VM.allThreads()` (by turning on the `enumeratevthreads` option), and by getting a `ThreadStart/Death` event for every vthread created/destroyed after connecting. This is basially how jdb used to work by default before any changes in this PR. There are 3 tests that rely on this behaviour and need this flag. They are `kill001`, `threads002`, and `trace001` (see below). Many more would rely on it if they were converted to use vthreads as these tests were. The bulk of the changes for this support comes from having to pass `trackAllVthreads` through all sorts of constuctors/inits. I wish there were a better way, but I couldn?t find a place to store this value as a static so it is easy to access. If you see a better way, let me know.
> 
> jdb: Track vthreads separately. jdb keeps track of every thread by creating a `ThreadInfo` for each and storing it in a `List<ThreadInfo>` called `threads`. I decided to store vthreads in a separate list. The reason is the list is needed by the `threads` command. It doesn?t use the `threads` list, but instead walks the `ThreadGroup` hierarchy and prints out the threads within each `ThreadGroup`. This doesn?t capture vthreads since they are not returned by `ThreadGroupReference.threads()`, even for the `VirtualThreads` group. So after the `threads` command has done its usual `ThreadGroup` traversal, it now also dumps all the vthreads. This is pretty much all hidden in `ThreadIterator.next()`, which automically transitions to getting threads from the vthread list after traversing all the `ThreadGroups`.
> 
> `nsk/share/jdb/Jdb.java`: Added support for `getThreadIdsByName()`: There are many jdb tests that use `Jdb.getThreadIds(<classname>)` to get all threads in the `threads` output that are an instance of `<classname>`. The problem is that after converting a test to support a vthread mode for all debuggee threads, the name of the class in the output will always be `java.lang.VirtualThread` (or `java.lang.Thread` when not in vthread mode), and not the test specific class name, which is usually something like `MyThread`.  Making `getThreadIds()` search for `java.lang.VirtualThreads` usually ends up including threads not wanted (ones that are not `MyThread`) such as the main test thread. So `getThreadIdsByName()` was added to allow searching by the thread name (actually just the prefix of the name) rather than its class. As an example, the `threads` command output used to contain a line such as:
> 
> `   (nsk.jdb.kill.kill001.MyThread)693            Thread-0            waiting in a monitor`
> 
> Now it contains:
> 
> `   (java.lang.Thread)693                         MyThread-0          waiting in a monitor`
> 
> So instead of searching for ?(MyThread)? and grabbing the threadId that comes right after it, `getThreadIdsByName()` first finds all the lines of output that contain ?nsk.jdb.kill.kill001.MyThread?, and then for those lines only gets the threadID that is right after ?(java.lang.Thread)? or ?(java.lang.VirtualThread)?.
> 
> jdb `kill001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. Use new `getThreadIdsByName()` support instead of `getThreadIds()`. Allow/expect the `kill` command to fail with "Illegal thread state? when in vthread mode.
> 
> jdb `threads002` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. I forget why I decided to convert this test. Seems it was useful for testing something I was working on for this PR, but I can?t recall. Maybe it was so I could clone it for the new `threads003` test below.
> 
> jdb `trace001` test: Convert to support all debuggee threads being vthreads by using `JDIThreadFactory`. Enable new jdb `-trackallvthreads` option. This is a test I had converted long ago when I first experimented with the `getThreadIdsByName()` support, so I included it with this PR.
> 
> jdb `threads003` test: This is a new thread test that tests jdb?s ability to learn about a thread when an event arrives on it. It creates 5 threads, two of which receive a breakpoint. It looks at the `threads` output and checks that only those two vthreads are present. I also used this test to help confirm that the `ThreadDeath` events are only received for these two vthreads. This was done manually by looking for the ?TDR removed? output generated by `EventHandler.threadDeathEvent()`. I didn?t put this into the test itself since that println is just for debugging and is now commented out.

Hao Sun has updated the pull request incrementally with one additional commit since the last revision:

  Fix build error after commit 6cad807
  
  Header "jfr/support/jfrThreadId.hpp" was removed in commit 6cad807,
  leading to the following build error:

Hi all,

  please review this small change to add code that disables the `-Wnonnull` warning for `JvmtiThreadState::state_for_while_locked`; the warning/error seems to be in error.

Thanks,

Sorry for the back and forth with the PR as I was trying out something; did not expect that anyone reviewed a draft. Since I'm not committer, you will need to bring it/sponsor I guess.

Looks good.  This helps readability and we need convince ourselves that there's no other way to get this small bit of performance back other than these templates.

src/hotspot/share/runtime/continuation.cpp line 2613:

I hate C++ template syntax.

This patch with additions and deletions of dummy stubs gets loom to compile on zero, ppc, s390, arm, linux 32 bit open, ie platforms that Oracle doesn't support.
There are two not nice 
#if !defined(AMD64) || !defined(AARCH64) || defined(ZERO)
changes.  One for platform dependent code in signature.cpp and the other is because linux zero product inlining detects the dummy null return as input to memcpy.
Also has a stack walking change that makes zero not complete compilation with the built compiler because of dummy returns.  Removing this doesn't cause any test failures in the loom tier1-3 code.

There's no need to introduce a new _keepalive_is_strong property in the G1CodeBlobClosure. The existing _strong is set to true when the evacuation participates in the marking of the old gen, which is when we need to mark the nmethods as "maybe on continuation". The name _strong in this context is not great and it doesn't convey the actual meaning. Maybe something for a future G1 cleanup.

Thanks for looking into this - that change has been one of the stranger to me as well.

Looks good.

There seems to have been an inadvertent change to argument to fix_relocations in full_process_roots. The bug doesn't cause any problems, it just calls an expensive operation (fix_oop_relocations) unnecessarily. Restore the old value.

The existing _strong is set to true when the evacuation participates in the marking of the old gen, which is when we need to mark the nmethods as "maybe on continuation". The name _strong in this context is not great and it doesn't convey the actual meaning. Maybe something for a future G1 cleanup.

I like these cleanups.  Only one I had a question about.  Thank you.

src/hotspot/share/runtime/continuation.cpp line 180:

> 178: #define VERIFY_CONTINUATION(cont) verify_continuation((cont))
> 179: NOINLINE static bool verify_stack_chunk(oop chunk) { return InstanceStackChunkKlass::verify(chunk); }
> 180: #define VERIFY_STACK_CHUNK(chunk) verify_stack_chunk((chunk))

Thanks for fixing this.  I know Ron likes to see the asserts have a line number of the caller but there's a PR to fix this and almost all of use some debugger to see where the assert comes from in the call stack, if it's not already in the hs_err file.

src/hotspot/share/runtime/continuation.cpp line 1160:

> 1158:     // properties of the continuation on the stack; all sizes are in words
> 1159:     intptr_t* const stack_top     = top_sp + ContinuationHelper::frame_metadata;
> 1160:     const int       stack_argsize = _cont.argsize();

I like this spelled out in the places it's used.  I wonder if _cont.argsize() is the stacksize of the stack chunk oops.  There are no comments really what it is.
cont_size seems to be the stack size of the entire continuation, ie the sum of all the stack chunk oops?  Dunno.  We're going to need some comments.

src/hotspot/share/runtime/continuation.cpp line 1213:

> 1211: 
> 1212:       chunk = allocate_chunk(cont_size + ContinuationHelper::frame_metadata);
> 1213:       if (UNLIKELY(chunk == nullptr || !_thread->cont_fastpath() || _barriers)) { // OOME/probably humongous

This is just a strange set of conditions.  Why would you allocate_chunk if  _thread->cont_fastpath() is false? or _barriers, whatever that means.  Really don't expect a function like allocate_chunk to have side effects.
Maybe in the latter two conditions, you still want to zero out the chunk in the tail and don't want to remove this.

src/hotspot/share/runtime/continuation.cpp line 1847:

> 1845:     assert((intptr_t)chunk->start_address() % 8 == 0, "");
> 1846: 
> 1847:     init_chunk(chunk);

I tried taking this out as an experiment because I thought after Java heap allocation, it would be already zeroed, but it wasn't.

Ok, thanks for confirming that it's already zeroed.

I guess if the callers are different, you can tell by the caller which is why this is seldom something I've noticed or thought needed fixing.

The existing _strong is set to true when the evacuation participates in the marking of the old gen, which is when we need to mark the nmethods as "maybe on continuation". The name _strong in this context is not great and it doesn't convey the actual meaning. Maybe something for a future G1 cleanup.

As noted by `jcheck`, the update in file `copyFailedInfo.hpp` has already been done in the `fibers` branch via commit https://github.com/openjdk/loom/commit/41d4ba55c

Besides, I further checked in my local environment that the `minimal` build can pass now with the latest code in `fibers` branch.
Hence, I'd like to close this PR.
Many thanks to all the reviewers anyway.

The existing _strong is set to true when the evacuation participates in the marking of the old gen, which is when we need to mark the nmethods as "maybe on continuation". The name _strong in this context is not great and it doesn't convey the actual meaning. Maybe something for a future G1 cleanup.

Hi all,

  can I have reviews for this change that makes garbage collectors explicitly transform stack chunks instead of relying on magic happening in `InstanceStackChunkKlass::copy_dis/conjoint`.

It also contains some refactoring suggested by @stefank in `Generation::promote`. Other than that it is a fairly straightforward change to replace `InstanceStackChunkKlass::copy_dis/conjoint` calls with explicit calls to `Copy::aligned_dis/conjoint_words` and `ContinuationGCSupport::transform_stack_chunk`.

This reduces code, and makes the code more understandable.

Test: tier1-5

Thanks,
  Thomas

Subject: RFR: Use single-condition instance type checks
Message-ID: <RX1imrzKtWVD-O8X_QqWGeBDkWiDDSRMh8Omf_N86Ik=.87cb5830-f5e4-4c06-836a-63500b8ba9c4@github.com>

Loom requires specialized code for stackChunks objects when marking/copying objects. This adds extra checks for every visited object. The current implementation checks both the layout helper, then checks the _kind flag. I suggest that we reimplement this as a single check against the Klass::_id field.

This change would probably be a good cleanup for the mainline.

Revert "Initialize ConstantPoolCache::_marking_cycle"

This reverts commit 42ad3454128d8ac360d0960001c22726951fa69a.

It caused also scratch classes to be unloading, reporting getting multiple instances of the same class.

Reducing the number of variables, the number of assignment to each variable, white-spaces, renamed some variables, removed unnecessary template, etc...
Except the removal of template 'bottom', the code is the same. (assert is moved up one level)

Passes 1-3 (no new failures)
It seem to be slightly faster than before, but at least on par.

This is not complete at all, but to avoid merge conflict I want to ship, and also make someone happy about removing a template.

Yes, the allocation returns memory without zeroing it.

The variable _barriers is set by allocate_chunk, so it must be check afterwards.
If allocation safepoints and there is JVM TI qeury it can 'remove' us as available for fastpath.
If allocation fails due to OOME.

The init_chunk() should always zero enought.

> Thanks for fixing this.  I know Ron likes to see the asserts have a line number of the caller but there's a PR to fix this and almost all of use some debugger to see where the assert comes from in the call stack, if it's not already in the hs_err file.

A better approach would be to print the line number in the assert:

InstanceStackChunkKlass::verify(chunk, __LINE__);
The assert would be assert(good, "%u: ....", lineno, ....) ;

_cont argsize is normally: inline int StackChunkFrameStream<frame_kind>::stack_argsize()
But it depends what we mean, a single intepreted frame must have the args from caller to be mounted.
But if caller is already mounted we already have those arguments.

Replace raw oop to stackChunkOops casts with calls to a ::cast function which asserts that the oops is a stackChunkOop. This is similar to what we do for other types like *Klass, *CollectedHeap, *Thread, ...

Given that we assert when converting oops to stackChunkOops, I've also removed the redundant is_stackChunk asserts.

Stefan Karlsson has updated the pull request with a new target base due to a merge or a rebase. The pull request now contains five commits:

 - Merge remote-tracking branch 'loom/fibers' into loom_checked_stack_chunk_casts
 - Allow nullptr in the cast function
 - Don't cast nullptr to oop
 - Remove redundant is_stackChunk asserts
 - Use cast function to convert from oop to stackChunkOop

I hate to be picky but I don't like that this had to move in_stack_reserved_zone.  We wanted to move all the stack overflow functions out of thread.
Can you pass thread to the overflow_state->in_stack_reserved_zone(thread, addr) instead?

I don't really like that, since it means stack overflow functions would need to know about virtual threads.  This function seems to be called in exactly one place, so I can just put the check in the signal handler where we check for arm32.

I can also imagine doing something like:

bool JavaThread::stack_reserved_zone_supported()

or

static bool FeaturesSupport::stack_reserved_zone_supported(JavaThread *)

but it seems like overkill.

Ok.

I guess all ways of fixing it spreads knowledge of virtual threads, which the thread code knows the most about.  I guess your original change is the best.  I moved all of those functions out of Thread but I guess this one has to go back.

Subject: Possible bug parking virtual threads with large stacks
Message-ID: <DM5PR06MB24448DB59D6E643501F16642C3189@DM5PR06MB2444.namprd06.prod.outlook.com>

Hello all,

A few of us at PayPal have been experimenting with the Loom binaries released over the past few months and while testing limitations, we ran into what we believe may be a bug. It seems that with many virtual threads with a large enough stack and light workload, a StackOverflowError occurs when parking a virtual thread.

Using the code below, on a GCP instance with 4 cores and 16GB ram, a StackOverflowError is thrown with a stack depth of roughly 2000 and 20 virtual threads with Thread.startVirtualThread(). Under 20 virtual threads does not produce this error. Adding some workload between each stack depth function call causes the error to disappear at 20 threads.

Using the ExecutorService from Executors.newVirtualThreadPerTaskExecutor() seems to increase these limitations.

public class TestStackDepth {
    static final int sleepDuration = 3600000;
    static int numThreads;
    static int stackDepth;
    static int workload;

    public static void run(int threadId, int stack, boolean logData) {
        BigInteger a = BigInteger.ZERO;
        BigInteger b = BigInteger.ONE;
        for (int i = 0; i < workload; i++) {
            b = a.add(b);
            a = b.subtract(a);
        }
        String s = b.toString();

        if (stack > 0) {
            if (logData && stack % 100 == 0) {
                System.out.printf("Thread %d: %d\n", threadId, stack);
            }
            run(threadId, stack - 1, logData);
        } else {
            if (logData) {
                System.out.printf("Thread %d in final depth %s\n", threadId, s.substring(0, Math.min(4, s.length())));
            }

            try {
                Thread.sleep(sleepDuration);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] argv) {
        numThreads = Integer.parseInt(argv[0]);
        stackDepth = Integer.parseInt(argv[1]);
        int execType = Integer.parseInt(argv[2]);
        workload = Integer.parseInt(argv[3]);

        ExecutorService executor = Executors.newVirtualThreadPerTaskExecutor();

        for (int i = 0; i < numThreads; i++) {
            int threadId = i + 1;
            boolean logData = threadId % (Math.max(1, numThreads / 10)) == 0;
            switch (execType) {
                case 1 -> Thread.startVirtualThread(() -> run(threadId, stackDepth, logData));
                case 2 -> run(threadId, stackDepth, logData);
                case 3 -> Thread.ofPlatform().start(() -> run(threadId, stackDepth, logData));
                case 4 -> Thread.ofVirtual().start(() -> run(threadId, stackDepth, logData));
                case 5 -> executor.submit(() -> run(threadId, stackDepth, logData));
            }
        }

        try {
            Thread.sleep(sleepDuration * 2);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

Running above code with arguments "20 2000 1 0" results in StackOverflowError.
Increasing workload to 1000 removes error: "20 2000 1 1000".
Using executor, stack depth can be increased to 3000: "20 3000 5 0".

Altering the code even slightly seems to change the depth at which the error is thrown, but it seems to be consistent when run on the same machine.

Thanks,
Mark

Hi.
Can you try warming up the test program to make sure this isn?t just an effect of interpreted methods and compiled methods having different stack-frame sizes?
Also, can you try increasing the maximum thread stack size with -Xss and see if that helps?

? Ron
