Hello everybody.

It looks like i found a bundle of bugs in last version of julia. I run an application which uses many Tasks in it. It also uses generated julia code, which is run inside these tasks all the time. I obtain these crashes after ~3-20 minutes of running in some random order. I used both debug and release julia versions for tests...

It's hard to provide buggy code sample, because application is big and so many processes are involved. But, i may provide a high level code:

module Test
  type Organism
    code::Expr
    codeFn::Function
  end
  type OrganismTask
    task::Task
    organism::Organism
  end

  tasks = OrganismTask[]

  function born(o::Organism)
    return function ()
      while true
        produce()
        try
          o.codeFn(o)
        end
      end
    end
  end

  function run()
    for i=1:500
      # in real app organism's function is more complicated
      org  = Organism(:(function (o) return 1 end), function (o) return 1 end)
      task = Task(born(org))
      push!(tasks, OrganismTask(task, org))
    end

    while true
      for i=1:500
        consume(tasks[i].task)

        # here is a code, which modify tasks[i].organism.code
        tasks[i].organism.codeFn = eval(tasks[i].organism.code)
      end

      # here is a code, which remove and add tasks from/to tasks variable
    end
  end
end

If it's hard to find these errors using my sample, you may run my project on your machine to obtain the same errors. It doesn't require some special environment fo run. I may provide you exact steps to reproduce it.

Thanks a lot. Julia is a great language ;)

Update: i found the code, which behaves exactly like my "abstract" example above. It crashes... :)

using Manager

orgs = Creature.Organism[]
len  = 500
# here, we just create 500 instances of type Creature.Organism
# it contains code::Expr and codeFn::Function, which we will
# change below...
for i = 1:len push!(orgs, Creature.create()) end

function run()
  local i::Int
  while true
    for i = 1:len
      # this code changes orgs[i].code expression in a random way,
      # but with correct julia syntax
      Mutator.mutate(orgs[i])
      orgs[i].codeFn = eval(orgs[i].code)
      try
        orgs[i].codeFn(orgs[i])
      end
    end
  end
end

run()

Code above produces this error:

I don't know :) I use eval() instead of @eval macro. And i don't use constants in my code. Also, in my case i have a crash instead of error, which is catchable.

Guys. Is there any solutions for this?

@StefanKarpinski

Without the rest of your code, this is hard to reproduce. If your code is available online, can you provide a link to it, or if you're willing to send it to someone privately, that would help too. That being said, I'm eyeing that eval inside of two loops as the culprit. You should generally not be using eval at runtime at all – eval should be used sparingly during program setup and then the main program execution should generally be eval-free. In this case, it seems like you're doing some kind of genetic programming with Julia code, however, which seems to inherently involve doing an unbounded amount of evaling.

@tmptrash

Yes, you right. This is a genetic algorithm related app. And i have to generate a lot of Julia code using AST. This is why i chose Julia ;) So i need to call eval() huge amount of times.

Here is an original code of this error :https://github.com/tmptrash/jevo/blob/master/tmp/err-crash1.jl

Run it in root folder using this snippet after clonning the repo:

include("src\\ImportFolders.jl")
include("tmp\\err-crash1.jl")
run()

But, you have to wait some time, before crash occures... For my PC, it takes ~4min... I tried this 5 min ago and i got this:

I can't reproduce your crash. It works fine for me but just runs for a very long time. Of course I'm on OS X, so maybe there's an upstream LLVM bug or some such issue.

I've run the test code you provided in your original post – the Test module, Test.run() – on OS X and Linux, versions 0.4 and 0.5 and none of them crash. They run for a long time and use a lot of memory but they don't crash. Can you confirm that this is the code that crashes for you:

module Test
  type Organism
    code::Expr
    codeFn::Function
  end
  type OrganismTask
    task::Task
    organism::Organism
  end

  tasks = OrganismTask[]

  function born(o::Organism)
    return function ()
      while true
        produce()
        try
          o.codeFn(o)
        end
      end
    end
  end

  function run()
    for i=1:500
      # in real app organism's function is more complicated
      org  = Organism(:(function (o) return 1 end), function (o) return 1 end)
      task = Task(born(org))
      push!(tasks, OrganismTask(task, org))
    end

    while true
      for i=1:500
        consume(tasks[i].task)

        # here is a code, which modify tasks[i].organism.code
        tasks[i].organism.codeFn = eval(tasks[i].organism.code)
      end

      # here is a code, which remove and add tasks from/to tasks variable
    end
  end
end

from the backtrace, it looks like one of your organisms tried to escape (create a new method), but didn't have the syntax quite right.

if you catch this in gdb, you should be able to walk up the stack to see the method body of the rogue organism

Regarding my "original" code, you right, it doesn't produce an error (but my last code (err-crash1.jl) does). So i found a solution how you may reproduce a crash on your side. I made small change in my code for serializing it just before crash. From this:

      orgs[i].codeFn = eval(orgs[i].code)
      try
        orgs[i].codeFn(orgs[i])
      catch e
      end

to this:

      orgs[i].codeFn = eval(orgs[i].code)
      try
        Helper.save(orgs[i], "err-code.jevo")
        orgs[i].codeFn(orgs[i])
      catch e
      end

You may load "err-code.jevo" using this function:

  function load(file::ASCIIString)
    local io  = null
    local ret = null

    try
      io  = open(file)
      ret = deserialize(io)
    catch(e)
      println("Error: $e")
      ret = null
    finally
      if io !== null close(io) end
    end

    ret
  end

To reproduce crash use this snippet:

org = load("err-code.jevo")
org.codeFn(org)

Last line in last code snippet causes a crash. But if i reevaluate the code it doesn't. I mean this:

org.codeFn = eval(org.code)
org.codeFn(org) # doesn't produce crash (only exception)

I tried to compare old and new generated ASTs using org.codeFn.code property and they are different. The big question here is why? May be many eval() calls during running somehow affect code generation?

P.S. Here is a link to "err-code.jevo".

I dived deep into the problem and found exact place of the error:

AST(:($(Expr(:lambda, Any[:(o::(top(getfield))(Creature,:Organism))], Any[Any[Any[:o,:Any,19],Any[:func_2,:Any,3]],Any[],0,Any[]], :(begin
        NewvarNode(:func_2)
        o = (top(typeassert))(o,Creature.Organism)
        $(Expr(:method, :func_2, :((top(svec))((top(apply_type))(Main.Tuple),(top(svec))())), AST(:($(Expr(:lambda, Any[], Any[Any[],Any[Any[:func_2,:Any,3]],0,Any[]], :(begin return func_2(97,8397162610081231316,-7678,-33) end))))), false))
        $(Expr(:method, :func_2, :((top(svec))((top(apply_type))(Main.Tuple,Int8),(top(svec))())), Type{LabelNode}, false))
        $(Expr(:method, :func_2, :((top(svec))((top(apply_type))(Main.Tuple,Int8,Int64),(top(svec))())), Int64, false))
        $(Expr(:method, :func_2, :((top(svec))((top(apply_type))(Main.Tuple,Int8,Int64,Int16),(top(svec))())), SymbolNode, false))
        $(Expr(:method, :func_2, :((top(svec))((top(apply_type))(Main.Tuple,Int8,Int64,Int16,Int8),(top(svec))())), Type{GenSym}, false))

        (Creature.stepDown)(o)
        (Creature.stepDown)(o)
        return (Creature.stepRight)(o)
    end)))))

It looks like the problem in one of last four $(Expr(:method, :func_2 lines...
For example the same generated code, which is work fine, but from previous eval() call is this:

AST(:($(Expr(:lambda, Any[:(o::(top(getfield))(Creature,:Organism))], Any[Any[Any[:o,:Any,19],Any[:func_2,:Any,3]],Any[],0,Any[]], :(begin

Hello guys!

It looks like this issue is not a duplicate of #14113, because it still reproducible on my PC. I have these crashes very often :( I waited for this fix and today i found that 14113 has fixed. It's critical, so i created a workaround making backups every minute and recover from last if crash occures. It's it really bother me...

So I made a special backup file with buggy code for you guys, but it depends on my modules (depends on Manager).

The scenario is the same. You have to import Manager into your code and load one object from code-before.jevo file like this.

include("src/ImportFolders.jl") # we have to be in a root folder of the project
import Manager
org = Helper.load("code-before.jevo")
org.codeFn(org) # this line produces the crash

This is the crash:

We've marked the commit for backporting to what will become 0.4.7. It will need testing against the release-0.4 branch to make sure it isn't breaking there. I'll try to find some time to prepare 0.4.7 over the next few weeks.

Hi. @tkelman, is it possible to prepare 0.4.7 with a fix? :)

No, sorry I've been occupied with 0.5 release candidates. Can you use them at all? I will be preparing an 0.4.7 release as the next thing on my to-do list after RC4.

see #18478 - though ref. #14656 (comment), not sure whether that particular fix is directly backportable without harming other functionality

No. Does v0.5 contain this fix also?
