moarvm's Introduction

MoarVM

MoarVM (short for Metamodel On A Runtime Virtual Machine) is a runtime built for the 6model object system. It is primarily aimed at running NQP and Rakudo, but should be able to serve as a backend for any compilers built using the NQP compiler toolchain.

Get It

Either download it from the MoarVM site or clone it from GitHub:

git clone https://github.com/MoarVM/MoarVM.git

If you use the automatically generated release tarballs or zip files please note that they don't contain the third party libraries needed to successfully build MoarVM.

Build It

Building and installing the VM itself takes just:

perl Configure.pl
make install

(Or nmake/gmake on Windows). Currently it is known to build on Windows with MSVC and gcc, and with gcc and clang on Linux & MacOS X. We're expanding this with time.

Type perl Configure.pl --help to see the configure-time options, as well as some descriptions of the make-time options/targets.

Building an NQP with MoarVM

After installing MoarVM, you can clone the NQP repository or grab a source tarball and use the Configure.pl script in it like so:

perl Configure.pl --backend=moar --prefix=where_your_moarvm_install_lives

Alternatively, the same Configure.pl script in NQP is able to clone, build and install a copy of MoarVM on its own if you supply the --gen-moar flag.

Please bear in mind that this will be the prefix to the /bin, /lib and other directories where the moar executable and other files are going to be installed, so you'll have to use /usr if you want moar to be copied to /usr/bin.

Building a Rakudo with MoarVM

When pointing the Configure.pl script in rakudo's repository at a --prefix that has an nqp-m installed in it, it will automatically detect and configure the MoarVM backend. Alternatively, --backend=moar,jvm can be used to force it to build the MoarVM and JVM backends, for example. Just like in the NQP Configure.pl script, you have the option to supply a --gen-moar flag that will do all the work for you, including creating an nqp-m.

Status

MoarVM is currently in development. It can run all of the NQP test suite, all of the Rakudo sanity tests, and passes more spectests than any other Rakudo backend.

Unlike the JVM or JS backend of NQP, the MoarVM repo is not integrated into the NQP source repo but instead can be pulled in by running Configure.pl --gen-moar configure script in the NQP repo.

Feature overview

Some key features provided by MoarVM include:

Meta-object programming, using the 6model design
Precise, generational, and parallel GC
Unicode 15 support (Unicode Character Database, encodings, normalization)
First-class code objects, lexical variables and closures
Exceptions
Continuations
Bounded serialization
Runtime loading of code
Big integers
A range of IO and process support, including asynchronous sockets, signals, timers, and processes
Native calling and native pointer manipulation
Threads, mutexes, condition variables, semaphores, and blocking queues
Bytecode specialization by type, and numerous optimizations (including resolution of method calls and multiple dispatch, dead code elimination, inlining, on stack replacement, scalar replacement, and partial escape analysis)
JIT compilation
Instrumentation-based profiling of call frames and allocations
Heap snapshotting
Remote Debugging with single stepping and variable/object introspection

Troubleshooting

Linker can't find appropriate symbols on macOS

If MoarVM fails to build, and the error looks something like this:

ld: symbol(s) not found for architecture x86_64

you likely have an incompatible mix of build and bin utils.

While it is common to have toolchains installed from third party repositories in macOS, they aren't all compatible. In the event you run into this issue, please try these steps.

Unlink your tools in homebrew: brew unlink binutils
Destroy and re-clone MoarVM or rakudobrew
Attempt the build again from scratch

If you want to use a GNU toolchain, and you get an error telling you to see this file, simply supply the --toolchain=gnu flag and this package will configure and build with a GNU toolchain.

Please note: If you use mixed Xcode and non-Xcode tools, you are likely to run into trouble. As such, this configuration is unsupported.

You need different code for `gcc` versus `clang`

Note both compilers define macro __GNUC__, so macro __clang__ needs to be tested first to disambiguate the two.

moarvm's Issues

Make lib directory target configurable

Hello,

In the process of packaging MoarVM for Debian I need to change the target directory of the library to support Multiarch.

This result in changing @prefix@/lib to @prefix@/lib/<triplet>.

Packaging only require a --libdir option to Configure.pl:

override_dh_auto_configure:
    perl Configure.pl --prefix=/usr --libdir=\$${prefix}/lib/$(DEB_HOST_MULTIARCH)

Regards

Change `MVMString` to `char` where it makes sense

Some immutable things like MVMREPROps could be compile-time constants (as in C static variables) if they did not contain MVMString* members (which are also less convenient for debugging).

It would make sense to change those to const char* and look up the runtime strings in a hash that hangs off instance. They probably could even be hashed by their address instead of their character data, making lookup reasonably fast.

The REPR names for REPR Xxx could be added to the hash by the corresponding MVMXxx_initalize() or lazily on access.

The name of an MVMContainerSpec is another candidate, and there are probably others.

"make test" output is LTA

~/git/MoarVM master* )$ make test
Please build nqp-cc and run the tests in there

This does not make much sense to a first-time MoarVM user, like myself. How do I build nqp-cc ? How do I "run the tests in there" ?

Move MAST files under ```/usr/share```

Hello,

Actually the MAST files are installed under /usr/lib/MAST, which at least does not conform to debian policy.

As noted in a suggestion of Raku/nqp#154, installing them under /usr/share/nqp/lib/MAST could be preferable, maybe versioned in the future to support multiple MoarVM installations.

This will require a change in tools/build/Makefile-Moar.in of NQP.

Clang warnings

Latest clang compiler throws about 500 warnings during compilation process:

http://pastebin.com/6yQTkhyV

change build scripts to allow --with-apr=OPTIONS and --gen-apr[=OPTIONS]

jnthn +1 if somebody wants to implement --with-apr={system,bundled}
FROGGS jnthn: what should be the default?
pmichaud I don't like that formulation
pmichaud by default it should use the system apr
pmichaud but there may also want to be a --gen-apr, which means to generate one locally
pmichaud similar to how we do --gen-nqp and --gen-parrot
pmichaud iirc, --with-xyz is supposed to provide the location of xyz
pmichaud checking
pmichaud oh, the standard also allows keywords to be there
pmichaud I'd be okay with --with-apr=gen then, where "gen" means download an appropriate version of apr
jnthn pmichaud: You really want it out of the repo? :)
pmichaud out of the main repo, yes.
jnthn ok
pmichaud I'm thinking we should handle 3rdparty libs similar to how we currently handle parrot/nqp in nqp/rakudo
pmichaud i.e., if you have it, use it, otherwise fetch from a known location and build real quick
pmichaud but somehow I feel like --gen-apr is more consistent with --gen-parrot and --gen-nqp
FROGGS true
jnthn Works for me.
pmichaud also, --gen-apr might even allow for version specifiers, similar to what we do with the other --gen-*'s

TODO: expose readlink as an NQP op

For File::Spec.resolve we need a way to find the destination of symlinks (readlink in POSIX and perl 5).

many spectests fail, due to binding to hash key

This binding here makes a lot of tests segfault:
https://github.com/rakudo/rakudo/blob/nom/src/core/CompUnitRepo/Local/File.pm#L62

When I change it to assigned it works.

Also, do get an error message at all one has to do:

Saying null string segfaults

It probably shouldn't.

#!nqp
use MASTTesting;

plan(1);

mast_frame_output_is(-> $frame, @ins, $cu {
        my $r0 := local($frame, str);
        op(@ins, 'say', $r0);
    },
    "", "say null string doesn't segfault");

Spesh: failed to fix up handlers (170, -1, 192)

This microbenchmark from perl6-bench blows up with spesh:

~/p/bench (master) [1]> perl6-m -e 'for ^32 -> $i { for ^32 -> $j { $i + $j }; 1 }; 1'

Spesh: failed to fix up handlers (170, -1, 192)

Function call fails if module is defined after it

This works fine:

module foo {
    our sub talk() {
        say("hello");
    }
}; 
foo::talk();

But this:

foo::talk();
module foo {
    our sub talk() {
        say("hello");
    }
};

fails with:

Cannot locate an outer frame for the call
   in frame_name_0
   in frame_name_15

look into whether zeroing can be made optional, once we're bug-free-ish

<masak> this comment doesn't seem to agree with the code: 
         https://github.com/MoarVM/MoarVM/blob/master/src/gc/allocation.c#L46
<masak> I might be wrong, but I expected to see a line of code that zeroes the memory that is returned.
<arnsholt> masak: Yeah, I agree

Segfault after repeated callframe access

This file (built with Rakudo = fd2b197, MoarVM = 0513b67) results in Moar trying to access a NULL string:

use v6;

sub proclaim($cond) {
    unless $cond { # for some reason, commenting this out fixes things?
        my $caller = callframe(2);
        say $caller.annotations.keys;
        say($caller.file);
    }
}

for (1 .. 20) {
    .say;
    proclaim(0);
}

Output:

I did a little digging, and I noticed that a GC happens shortly before the crash.

gen2 overflow list compaction

We maintain a list of gen2 objects that are too big for the sized pools. This overflows list has any freed items NULL'd. But, we never compact it, so it lots of large objects are allocated then go free we'll eventually eat all memory. Not a hard fix, just needs doing.

Heap corruption detected: pointer 0x7fee3d952a90 to past fromspace

Apparently I managed to trigger a rare error.

https://github.com/ren1us/Research/tree/c6f0e900b8998c81f7f7b0c514168d9972dce1e8
(Commit c6f0e900b8)

I haven't been able to reproduce the crash.

Running: perl6 -Ilib t/Prune.t

I got the error during the second call to testRun (Prune.t). The first say statement (line 19) fired correctly, but the second one (line 28) did not, so the error was probably triggered somewhere in there. Note that this code will crash on the third call to pick_prune unless you add "is copy" to $pos. In a perfect world, it'd go on for another 1100 calls.

I honestly have no idea what I'm doing, but if I can provide any more context or whatever, I'm all yours.

Make Configure.pl detect when 3rdparty libs are too old

<FROGGS> looks like your 3rdparty libs were built ages ago
* masak realcleans and tries again
<masak> is it unreasonable to expect the Configure.pl process to stop-and-emit something like "looks like your 3rdparty 
         libs were built ages ago" ?
<masak> (worked now.) FROGGS++
<FROGGS> I guess we make it nicer when moarvm has more than ten users :o)
<masak> there is that.

2014.01.tar.gz does not include dyncall and libuv

Somehow the dyncall and libuv repositories got missed in the release tarball, so it’s pretty useless as is …

extend hash to traverse trees

note this also has a dependency on fixing the tree strings so they don't need flattening after every creation op too :)

22:17 < diakopter> oh, another todo :)
22:17 < diakopter> extend the hash algorithm to be smart enough to traverse tree strings instead of requiring all strings to be flattened before used as
hash keys
22:18 < diakopter> the machinery to make the traversal modular enough should already mostly be there
22:18 < diakopter> should I add it as an issue?
22:18 < not_gerd> does it make sense to cache the hash value?
22:19 < diakopter> yes
22:19 < not_gerd> having it around is also useful for eq
22:19 < not_gerd> do we already do it?
22:19 < diakopter> don't think so
22:19 < diakopter> though I might've put a slot in for it

Consistent naming for REPRs

The REPR name occurs in various places, among those the prefix of C structures and functions, file names, the MVM_REPR_ID_* constant and the actual user-exposed name member of the MVMREPROps structure.

Some names have a VM prefix for vm-specific but multi-backend types and some purely MoarVM-specific types have a MVM prefix.

For readability, both C prefixes MVMVM and MVMMVM get shortened to MVM. However, we also lost the distinction between VM and MVM REPRs where we need not do so, in particular the file names and REPR-ID constants.

For consistency, these should match their authorative, user-exposed names - eg MVMString should be kept as-is, but MVMArray.c, MVMArray.h and MVM_REPR_ID_MVMArray should be renamed to VMArray*.

[Windows] Configure fails when path in --prefix doesn't exist

Configure.pl dies on line 70 with the error "No such file or directory". Seems that abs_path requires the path to already exist, at least on windows.

C:\Users\dagurval>perl -e "use Cwd qw(abs_path); abs_path(qq(C:/doesnotexist))"
C:/doesnotexist: No such file or directory at -e line 1.

I'm using this workaround:

if (defined $args{prefix}) {
    mkdir $args{prefix} or warn "mkdir $args{prefix}: $!";
}

Unicode: Case folding special cases

The spectests have caught some cases where moar's case folding isn't sufficient.

In particular, in https://rt.perl.org/Ticket/Display.html?id=121377 I discuss some case folding rules for the German ß

'ß'.uc;   # should be 'SS'
'ß'.tclc  # should be 'Ssß'

Also, S32-str/lc.t has this test:

is 'ΣΣΣ'.lc, 'σσς', 'lower-casing of greek Sigma respects word-final special case';

which raudo-jvm and rakudo-parrot get right, but moar fails (it produces σσσ).

Cannot build libapr on ubuntu

I got this error on my ubuntu machine.

I added -luuid to $LLIBS then work.

TODO: Need some kind of safe mode

For the IRC evalbot, but also for other applications, it would be nice to have some kind of safe mode that disallows file and socket IO, and things like spawn/shell.

I'm fine with it being a configure-time option, a command line option, environment variable or anything really.

spesh inline bug: using default in for loops doesn't work correctly

The code below outputs 1 to 17 followed by a bunch of Nils rather than 1 to 50. Enabling MVM_SPESH_INLINE_DISABLE causes it to run correctly. As does using when * instead of default.

for 1..50 { default { say $_ } }

spesh bug with perl6-lwp-simple get-w3-latin1-utf8.t

FROGGS++ already gdb'd this one and looked into it: https://gist.github.com/FROGGS/9228162347e3b4c03a18

running lwp-simple's t/get-w3-latin1-utf8.t segfaults on moar: dcc3a47 nqp: 6cc7d6ec rakudo: cfc0b38.

MVM_SPESH_DISABLE=1 prevents the segfault. I tried to golf it down to fewer lines of test, but was unable to cause the segv with any of the combinations I tried (only doing one GET, only matching once, running no tests, etc).

Shift operations are under-specified

First of all, MoarVM lacks a distinction between logical and arithmetic shifts. As the i64 member of the MVMRegister type is used, we end up with arithmetic shifts, and ops for logical shifting are missing.

Second, shifts by invalid bit counts (negative values or values greater than the integer type's width) result in undefined behaviour, making such programs non-conforming C (in fact, clang returns bogus numbers if it detects an invalid shift in a constant expression).

I see two ways to go from here:

choose the Java route and mandate two's complement/x86 behaviour; we get this by forcing the 2nd operand within the range of well-defined values (in case of 64-bit integers via i & 63 or i % 64)
choose the Parrot route, which sanitizes the semantics: negative bit counts shift in the opposite direction, and shifting by a value greater than the type's width returns 0 as all bits have been moved out of range

The former is more low-level, the latter makes more sense.

A third issue is the handling of negative values. This is implementation-defined in C. In practice, we'll probably end up with two's complement behaviour, ie

shr $a, $b = floor($a / 2**$b)

Arguments could be made that sign-magnitude behaviour

shr $a, $b = trunc($a / 2**$b) = $a div 2**$b

might be preferable, as it is more consistent with the rest of integer arithmetics.

NQP build failure on big-endian platforms

Got this build failure on OpenBSD/powerpc, looks like it is endian-related:

)

Flattening hashes into argument list behaves incorrectly

sub a(:$x) { say $x }; a(|{x =>'first'}, |{x => 'last'}) outputs first on MoarVM rather than last. It works correctly on the other backends. sub a(:$x) { say $x }; a(x =>'first', x => 'last') works as expected and prints last.

I found this when attempting to do sub a(:$a, :$b) { say $a + $b }; &a.assuming(:a(5))(:a(2), :b(2))

This was discussed on IRC briefly from http://irclog.perlgeek.de/perl6/2014-08-25#i_9240510 onwards. There're a few other issues, but they're not MoarVM specific.

Segmentation fault: Int but False

Int but False, or more specifically Int.clone(), segfaults on MoarVM.

Golfed moarvm precompilation issue

I believe this may be caused on the MoarVM level. If not, I can recreate this ticket for nqp or rakudo.

Reproduction available here: https://gist.github.com/retupmoca/9953591

Typed arrays seem to be causing an issue when in multiple use'd modules at the same time. Real-code examples of this include Net::DNS and Compress::Zlib::Raw (the latter will not currently run on windows machines).

libmoar.so should be versioned

The ‘moar’ binary directly links to libmoar.so, meaning it should be versioned. Unfortunately, shared library versioning is vastly different between operating systems. For instance, OpenBSD uses a .so.X.Y scheme, FreeBSD has a .so.X scheme, and most Linux distributions use some kind of .so -> .so.X[.Y] symlink scheme. These differences should probably be handled by setup.pm; in any case, it would also be nice to allow packagers to easily override the library version.

import dyncall (a la nqp on parrot)

~~import dyncall from nqp-parrot to MoarVM/3rdparty/~~
~~integrate it with the build system~~
port the 6model representations
port the relevant nqp:: ops
test, I guess.

Add "how to link to Moar" option to configure hash

Rakduo currently uses a @moarimplib@ hack for Windows and OS X to specify how to link to Moar's shared library. This should probably be figured out by Moar's configure and passed as part of the config hash instead.

Strange-ish lexical behaviour, please review

I was working on implementing JIT getlex / bindlex and I noticed some strange-ish behaviour in getlex. Specifically, to determine if a NULL has to be vivified into an object / vmnull, getlex checks for an entry in the 'lexical type' array.

This lexical_type array either comes from the spesh candidate (if present) or from the static frame. The frame is then passed - along with the index - to MVM_frame_vivify_lexical.
But MVM_frame_vivify never looks at spesh_cand->lexical_types. So that's a bit strange.

Furthermore, MVM_frame_vivify_lexical seems to be happy to accept an index greater than what will fit into the lexical_types array of the static frame, and if it doesn't fit, will look at the static frames' lexical type arrays of inlined spesh static frames. But getlex never bothers to check if the index is within the bounds of the lexical_types array.

So in short, the use of lexical_types in OP(getlex) and in MVM_frame_vivify_lexical (and possibly elsewhere) doesn't seem consistent, and possibly buggy.

What I'd like to do is move the decision between the two types of lexical types up to frame invocation level, that is to say, add a field 'effective_lexical_types' to MVMFrame. Furthermore, I'd also like to 'merge' the lexical type arrays of inlines, which i /think/ shouldn't be a problem, because apparantly indices are already moved about during inlining, as they obviously should.

Change bytecode stream type to MVMuint16

Currently，cur_op type is MVMuint8 (see src/core/interp.c MVM_interp_run), changed it to MVMuint16, so #define NEXT_OP (cur_op += 2, *(MVMuint16 *)(cur_op - 2)) can be changed to #define NEXT_OP *(cur_op++).

This work also contains changing part of MVMuint8 type to MVMuint16 in MVMThreadContext struct, and MVMStaticFrameBody, MVMCompUnitBody etc.

--clang should be a more generic --cc=clang

Since configure defaults to clang on OS X, it would be nice to have a way to go back to gcc. And rather than proliferating --compiler flags, they should be arguments to a general flag.

Speculationg: In theory this could allow users to specify completely unknown compilers, if they could also specify cflags, ldflags, etc.

pow_I needs fixing

In 091a236 I made it work-ish, but it still needs some work to handle the Num fallback. See other backends for more info; probably Parrot is best one to see as it also uses libtommath.

cache immutable created runtime things

22:19 < diakopter> another todo:
22:20 < diakopter> all the string literals in the moarvm source where we construct MVMStrings from C literal strings (without format)... should be cached in a struct that hangs off MVMInstance
22:20 < diakopter> (and all rooted)
22:21 < diakopter> (and their constructor calls obviously set to lookup in the cache)
22:21 < diakopter> parrot has a convenience function for this
22:22 < diakopter> there are already a few strings cached on Instance like that ->Str , ->Num, ->Empty I think
22:22 < diakopter> but it needs generalized
22:22 < diakopter> further generalized would be to find any unchanging/immutable things created by runtime code and make those cached too
22:24 < diakopter> could even make the .h that stores their slots generated if you use a macro sneakily

Roles break lexical scoping

Two examples:

role R { method m() {} }
class C does R {}
C.new.m;

fails with

Cannot locate an outer frame for the call

and

role R { say(42) }
class C does R {}

fails with

No lexical found with name '&say'

The failure of the first example can be tracked to an intermediate frame that breaks the fallback mechanism of MVM_frame_invoke() - see https://gist.github.com/gerdr/babe2cbd5d85c9170dec for details.
