Is Poolboy supported on Windows?

[ghost]

I tried using poolboy in my Elixir program on Windows. Mix fails to compile it. Something about rebar.

>mix deps.compile
==> poolboy (compile)
Compiling src/poolboy.erl failed:
src/poolboy.erl:17: type queue() undefined
ERROR: compile failed while processing c:/Users/my_user/Projects/my_app/deps/poolboy: rebar_abort

On Mac it complied fine:

$ mix
Could not find "rebar", which is needed to build dependency :poolboy
I can install a local copy which is just used by Mix

That's an erlang version difference problem. Your erlang on windows is probably older.

[devinus]

@ejstembler What is your Erlang version on Windows?

Give me the output of erlang:system_info(otp_release).

[ghost]

It looks like both are the same, 18. On my Windows 8 x64 VM:

>erl
Eshell V7.0  (abort with ^G)
1> erlang:system_info(otp_release).
"18"
2>

On my Mac OS X El Capitan:

$ erl
Erlang/OTP 18 [erts-7.1] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Eshell V7.1  (abort with ^G)
1> erlang:system_info(otp_release).
"18"
2> 

[OnorioCatenacci]

This isn't really a bug. You just need to install Rebar on your Windows machine. http://theburningmonk.com/2014/08/getting-started-with-rebar-on-windows/

[OnorioCatenacci]

By the way, Eshell v7.0 is not the same as Eshell v7.1. They're both major version 18 but they're different minor versions.

[devinus]

@OnorioCatenacci Wont mix download rebar automatically if not found?

[OnorioCatenacci]

That's a good question. I'm not sure. I just manually downloaded rebar
when I needed it (there was some other dependency in Phoenix that needed
rebar at one point).

Here's something that may have relevance: elixir-lang/elixir#2152

While the bug mentioned may have been fixed last year it's still worth taking a look at the comments.

[ghost]

@OnorioCatenacci I cloned rebar, compiled it locally, then added it to my path. The output:

[OnorioCatenacci]

That wouldn't have been the way that I would have suggested to get rebar
but no matter. What do you get when you type "rebar" at a command prompt?
That's the simplest way to insure rebar is set up and running correctly and
in the path.

@OnorioCatenacci Well, I followed the instructions on the link you provided on the mailing list.

In any case, typing rebar was the first thing I did after modify my path, and starting a new terminal window. It complains about no parameters and displays the usage:

>rebar
No command to run specified!
Usage: rebar [-h] [-c] [-v <verbose>] [-q <quiet>] [-V] [-f]
...

Also, on Windows I can do a where:

>where rebar
C:\Users\my_user\Projects\rebar\rebar
C:\Users\my_user\Projects\rebar\rebar.cmd

[OnorioCatenacci]

Ok--just to insure we're all playing from the same playbook: type rebar
version and post the message. There are a few different versions of rebar
available and we can help you better if we can insure we're all working
from the same version of rebar.

Also I'd try calling rebar directly (as opposed to calling it from within
mix) like so: rebar compile poolboy

From a command prompt within the poolboy directory of course.

All of this is not to say that mix shouldn't work with this but it's easier
to isolate the problem if we can find something that does work and then
compare that to the non-working path.

Just my suggestions of course.

@OnorioCatenacci Sure. Good suggestions. Here's the output:

@devinus I'm not privy to the poolboy source, however, where is queue coming from in src/poolboy.erl:16? Is it imported from somewhere?

[OnorioCatenacci]

Devin can comment more on this but I believe this would be the queue in
question:

http://www.erlang.org/doc/man/queue.html

One thing though--it looks like the code is thinking Erlang is "pre17"? I
mean this:

-ifdef(pre17).
-type pid_queue() :: queue().
-else.
-type pid_queue() :: queue:queue().
-endif.

I don't think your version of Erlang is pre17 (I'm assuming that's 16 or
earlier) in any case so that seems suspect to me. I'd wonder why you're
getting that.

I'd also suggest that you check your code path in Erlang. See if you've
got a queue.beam file under your Erlang folder. On my machine I have
queue.beam at c:\program files\erl7.1\lib\stdlib-2.6\ebin. Erlang/Rebar
would be trying to find that queue.beam file (as far as I know).

Yeah, I do have queue.beam in C:/Program Files/erl7.1/lib/stdlib-2.6/ebin/.

Anyone know how pre17 gets set? It doesn't come up when I search the erlang or rebar repos. I see a reference to in the poolboy's rebar config though: rebar.config:3. I'm not sure what that means, but I found a previously closed issue with the regex: compile fails with erlang 18

[devinus]

@ejstembler You don't have pre17 though, you're on a release of 18. I'm not sure how your release of 18 doesn't have the queue type honestly.

[OnorioCatenacci]

Maybe it's a codepath issue? I forget how to check the codepath. But it
seems as if it were a codepath issue he'd be seeing more issues than just
poolboy.

@ejstembler I'm not sure how you installed Erlang or Elixir, but it seems messed up.

1. Install Erlang 18.1 64-bit using the installer here: http://www.erlang.org/download.html
2. Install Elixir 1.1.1 using the installer here: http://elixir-lang.org/install.html

Devin@desktop MINGW64 ~/Projects/poolboy (master)
$ ~/.mix/rebar compile
==> poolboy (compile)
Compiled src/poolboy_sup.erl
Compiled src/poolboy_worker.erl
Compiled src/poolboy.erl

[ghost]

@devinus That's what I had before. However, I uninstalled everything to be safe, rebooted, and re-installed. I used:

• otp_win64_18.1.exe Erlang 18.1 64-bit for Windows
• elixir-websetup.exe the Web Installer for Windows

Checked the versions from the shells:

>erl
Eshell V7.1  (abort with ^G)
1> erlang:system_info(otp_release).
"18"

>iex --version
Eshell V7.1  (abort with ^G)
Elixir 1.1.1

Wheres:

>where erl
C:\Program Files\erl7.1\bin\erl.exe

>where iex
C:\Program Files (x86)\Elixir\bin\iex
C:\Program Files (x86)\Elixir\bin\iex.bat

I get the same output though:

I deleted my cloned copy of rebar, and tried again:

It seems like it's trying to use the version of rebar mix includes. But it fails too.

[devinus]

@ejstembler Try deleting ~/.mix/rebar and doing mix local.rebar.

After that, try cloning poolboy itself and then using ~/.mix/rebar compile and report back.

[OnorioCatenacci]

rebar itself is an escript. So yes, you'd need a bat or cmd file or
something of that sort to start rebar via escript. Here's mine:

@OnorioCatenacci @devinus I got it to work! Thanks for your help Devin and Onorio!

C:\Users\my_user\Projects\my_project\deps\poolboy>c:\Users\my_user\.mix\rebar compile
==> poolboy (compile)
Compiled src/poolboy_sup.erl
Compiled src/poolboy_worker.erl
Compiled src/poolboy.erl

I created a rebar.bat similar to how they do their bootstrap.bat

@echo off
escript.exe rebar %*

So, maybe the issue is that Elixir (or mix?) needs to create that additional rebar.bat file for Windows?

[devinus]

@josevalim Thoughts?

[tymoor]

Was this ever resolved? I'm getting the same error after installing Elixir and Erlang via the elixir-websetup.exe ... it appears that mix is correctly passing rebar to escript:

What is your Windows, Elixir and Erlang versions? I am confident Poolboy
works on Windows, so we need to identify what is missing in your setup.

Due to the error, it seems your issue is either an old Poolboy version (try
updating it) or an old Erlang version. It seems tone the former.

Yeah, that was it - when I got to the hex page ( [(https://hex.pm/] ) I just copied the ecto tuple it suggests:

Using with Elixir

Simply specify your Mix dependencies as two-item tuples like {:ecto, "~> 0.1.0"} and Elixir will ask if you want to install Hex if you haven't already. After installed, you can run $ mix local to see all available Hex tasks and $ mix help TASK for more information about a specific task.

into my sample program... that tuple is old, and has a dependency on an old version of poolboy.
