v8worker's Issues

No rule to make target `third_party/icu/icu.gypi'

hi @ry any thoughts about this?

I:v8worker chris$ make
version=4.3.59 target=x64.debug  ./build.sh
++ dirname ./build.sh
+ cd .
+ make -C v8-4.3.59 i18nsupport=off x64.debug
make[1]: *** No rule to make target `third_party/icu/icu.gypi', needed by `out/Makefile.x64.debug'.  Stop.
make: *** [v8.pc] Error 2

OS X Yosemite
Version 10.10.2

multiple goroutines calling worker.Send

Is this access pattern allowed / supported ? or is the program responsible for synchronzing this (e.g. mutex)?

any ideas how to kill a worker? (from the TODO list)

thank you for creating this package.

make install failed

On Mac 10.9, 'make' is completed, but 'make install' is failed with error massage as below:
./binding.cc:6:10: fatal error: 'v8.h' file not found
How to set cflags -I./v8.include for this?

cannot compile

linux, depot tools installed and are in the path
go get github.com/ry/v8worker
gives me
Failed to open 'v8.pc': No such file or directory

Any advice?...

Passing code instead of file

Hi
it is possible to pass a bunch of javascript code instead of file?

Thanks

Why there will be this project, when will this project be useful ?

FYI

synchronuous calls, Go <-> Js

Hi,

I have been working on 2 extensions to your v8worker project (see my fork).
Two additional Javascript keywords have been introduced to allow synchronous calls from Javascript to Go and vice versa.

var response = $request("ping");

which will call the Go function with this signature:

type RequestMessageCallback func(msg string) string

and in Go

response := worker.Request("pang")

which will call the function set as the handler:

$request_handler(function(msg) {
        return msg;
    });

At his point the code is working and would love to get some feedback.
I am using these extensions such that I can replace the otto package which provides these calling scenarios. In my case, I will send JSON messages back and forth that represent function calls and return values.

Can't build package because it contains C++ files (binding.cc) but it's not using cgo nor SWIG

I'm trying to cross compile v8worker for multiple platforms via gox (https://github.com/mitchellh/gox) but it's complaining that cgo nor SWIG is used.

I don't think it's a cgo nor SWIG issue but it probably requires some changes to the Makefile.

Questions: cloning, binary size, namespace

Hello,

I have some questions.

Cloning the worker state (variables)

I dream of doing something like:

js: $sendSync(...)
go: recvSync(...) {...}
clone the state of the worker at the point of the $sendSync was called
spin up another worker with the same cloned state
work in the clone, mess up everything, get some results
return to the original worker
have it just like it was.

Could that be made?

Binary size

When I build my tiny project the binary is over 100M. I read that with gcc V8 will be under 10M but I understand my binary has everything linked statically. I'm a total noob with go, haven't really done anything with c++ and don't know where to start. Any info is appreciated.

Namespace

Those $rect, $print etc. are fairly nice but I'd prefer these names customisable, perhaps having them inside an object (foo.print, foo.send, ...). Looking at the code this seems achievable but do you think this is a totally retarded idea?

Anyways, thanks for creating this fine tool. I will have lots of fun with it.

Observing strange issue with SendSync

At some moment SendSync returns an empty string instead of the result.
In my case, it happens right after calling another package with C bindings (https://github.com/gographics/imagick)
My code:
data := JSWorker.SendSync(opts)
with some probability, data contains empty string instead of a result. looks like a goroutines multithread issue.

v8worker and http.Handler [signal arrived during cgo execution]

hey @ry I am trying to make v8worker work with http.Handler it works for first request then it breaks, any thoughts about this?, thanks in advance.

package main

import (
    "log"
    "net/http"

    "github.com/ry/v8worker"
)

var (
    JSCode string
)

func init() {
    JSCode = `
        $send("hello world");
    `
}

func rootHandler(w http.ResponseWriter, r *http.Request) {
    V8Worker := v8worker.New(func(msg v8worker.Message) {
        log.Printf("msg: %v", msg)
    })
    if err := V8Worker.Load("code.js", JSCode); err != nil {
        log.Printf("failed to load js file. error: %v", err)
    }
    w.Write([]byte("ok"))
}

func main() {
    http.HandleFunc("/", rootHandler)
    http.ListenAndServe(":8080", nil)
}

Go 1.6 is more strict: cgo argument has Go pointer to Go pointer

Today, at FOSDEM in Brussel, I learned about a new compiler change regarding the use of pointers in cgo. Wondering if this would affect v8worker, I tried building the project using 1.6rc1. I hope we can find a way to play by the new rules.

Slow compile time

One of the amazing things about Go is how fast it compiles. Since installing the great v8worker lib, my build time has slowed from <1 second to around 20 seconds. This really slows down the TDD workflow that I normally use, because I'm waiting 20 seconds for a unit test to run.

Any suggestions on how to avoid recompiling the v8worker every time I make the project?

Support building the entire project using only the `go build` command

I'm not an expert at V8 or Go, so forgive me if this is naive, but it seems like one of the pain points of v8worker is that it requires that users run make and therefore doesn't build with a simple go build (as seems to be standard in Go projects these days). This means that downstream projects can't use go build for their build system, as well as their downstream projects, and so on.

If you're open to it, I'd like to explore alternatives to the current solution. If any of them sound acceptable, I can do the legwork myself to implement it. Below are a few as I see them, please correct me if I'm wrong on something -- like I said, new to go, new to V8.

Allow users to build against system installations of V8, instead of building it specifically for the solution. This might require code changes to the C code that uses V8 to make it more compatible with later versions, or we might have to state our version dependencies right up front. We'll also have to figure out how we want to handle the pkg-config stuff we're generating -- I don't know the answer to that off the top of my head, aside from using more static flags in our cgo calls.
Add v8worker to the usual package manager suspects -- brew, apt-get, etc. Labor-intensive, and annoying to maintain, but possibly worth it. Nonstandard for go, but at least it is compatible with go build and involves only a few more commands, to get the packages themselves.
Add some support for v8worker "distributions", which possibly would avoid the problems of configuring and generating the configuration stuff, like pkg-config, but not the problem of building V8 itself. This could be used in conjunction with the first option.

Open to other suggestions as well. Let me know what you think.

Debug JavaScript runtime errors

Hi!

Is there any opportunity to somehow debug JavaScript runtime errors (on the server side of course)?

Reason for v8 in source code

Is there any reason for v8 to be checked into the source code ? Can we fetch it using depot tools only ?

Have you seen Nim

Have you seen Nim https://github.com/nim-lang/Nim?
Might never be popular like Go but its really interesting.

This doesn't actually have anything to do with v8worker. Please feel free to close. Sorry to bother you.

Cannot create multiple workers

worker1 := v8worker.New(func(msg Message) {})
worker2 := v8worker.New(func(msg Message) {}) // <-- segfault

Cause is V8::InitializePlatform() being called in v8platform.New()... it should only ever be called once.

Probably the best thing to do is wrap it in sync.Once

Running: gclient sync --nohooks --with_branch_heads

why stop this? always running!does not sent any error. on centOS.thank you .if you can tell the reason

A way to destroy a worker

I need to use multiple worker instances and when one worker finishes I need a way to destroy an instance and free the memory
Afaik in current implementation memory will never be freed

What would you suggest?

Workers not GCed when in tight loop

I'm running into a memory problem with v8worker when running this test program on go version go1.6 linux/amd64. It's replicating an issue that I see when many workers are created and 'destroyed' so that each script runs in a clean environment.

package main

    "fmt"

    jsvm "github.com/ry/v8worker"
)

func main() {
    var i int
    for {
        i++
        fmt.Printf("Running, %d time\n", i)
        run()
    }
}

func run() {
    vm := jsvm.New(nil, nil)

    err := vm.Load("mytest.js", `
            // Do something
            var something = "Simple JavaScript";
    `)

    // Check for exceptions
    if err != nil {
        fmt.Println("Error:", err)
        return
    }
}

'memset' was not declared

On Ubuntu 14.04 AMD64 platform, make to build v8 without problem, hit issue when install

$ go install
# github.com/ry/v8worker
./binding.cc: In member function 'virtual void* ArrayBufferAllocator::Allocate(size_t)':
./binding.cc:30:56: error: 'memset' was not declared in this scope
     return data == NULL ? data : memset(data, 0, length);
                                                        ^

    $git checkout HEAD^^
    $ go install
# github.com/ry/v8worker
./v8/out/native/obj.target/v8_libbase/src/base/logging.o: In function `v8::base::DumpBacktrace()':
../src/base/logging.cc:(.text._ZN2v84base13DumpBacktraceEv+0x67): undefined reference to `dladdr'
collect2: error: ld returned 1 exit status

Apply patch from mmurray@177013e fixed the dladdr issue.

One else memory leak fix

Hi Ryan!
Check out our last change for worker:
getblank@9a5963b#diff-0003efb78f2f135c88ca5431b8353b2cR261

It did fix memory leak in SendSync

Migrating from Otto to v8worker

In Otto we exposed a GO object to JavaScript so that the user can access the content and the object itself.

For example the content is stored in the variable 'data' and contains a 'time.Time' field named LastUpdate (actually several, based on many different data formats). To perform calculations on that object in JavaScript we need convert the time object to a unix timestamp and in Otto this is as simple as:

var lastUpdate = data.LastUpdate.Unix();

But in v8worker this will result in an error message as the object is not linked, which makes sense but implementation a lot harder, specially because a date object in GO does not become a JavaScript date but a textual representation (which we could parse).

Any suggestions how we could make this migration easier (without a need to rewrite all user scripts) or pass an object from GO to v8?

Global`window` object not available; nor "built-in" functions

Not sure if this is supposed to be a feature; but the window object is not available to the loaded script so neither are the functions setTimeout, setTimer, atob or btoa available

GOMAXPROCS and v8worker

I've quickly tried simple benchmark for parallel execution, and I found
increasing GOMAXPROCS don't improve performance for v8 as expected.
Is this expected as v8 is running in single thread? or this can be improved?

nueno-mbp15:go_javascript[master *]$ GOMAXPROCS=1 go run benchmark.go
otto parallel test
otto parallel thread : 32.483853059s
v8 parallel test
v8 parallel thread : 64.419895ms
golang parallel test
golang parallel thread : 3.3833ms

nueno-mbp15:go_javascript[master *]$ GOMAXPROCS=8 go run benchmark.go
otto parallel test
otto parallel thread : 7.675539588s
v8 parallel test
v8 parallel thread : 74.098425ms
golang parallel test
golang parallel thread : 962.457µs

Here is my simple benchmark code

Add support for node module loading

This is a feature request.

A major use case for v8worker might be to load a node.js module (which may itself require more node modules as dependencies) to perform work, and then return the result back to golang. It would make v8worker much more useful if it has node module loading built in.

build with Docker

After spending a few days of trial and analysing build errors, I finally got a working Docker based build for v8worker based apps , see https://github.com/emicklei/v8worker-docker. The only thing I needed to change was to add the --nohooks flag to fetch.

Happy building
