That's going to be difficult to figure out, because I am using the same versions and don't get the error:

jason@jason-tk:~/workspace/ufront/hello$ haxe -version
3.1.3
jason@jason-tk:~/workspace/ufront/hello$ neko -version
2.0.0
jason@jason-tk:~/workspace/ufront/hello$ ufront build
Build tasks.hxml
Build server.hxml
jason@jason-tk:~/workspace/ufront/hello$

But anyway, let's see if we can figure this out.

The regex in question is this one:

static var paramPattern = ~/^([^=]+)=(.*?)$/;

Now:

• That regex should be fine.
• But apparently it's using a feature that's not available at macro time.
• Why is it being used at macro time??
• Ufront uses macros in a few places, (like controller routing), and I guess the HttpContext is being loaded, and hence the HttpRequest file.
• When it loads, it tries to type the class (though I imagine it doesn't ever execute it)
• When it types the class, it tries to type var paramPattern, and so has to load the expression
• It loads the expression, meaning it instantiates the EReg, even though it'll never get used, and it runs into the error.

In terms of fixing this...

1. I think the easiest solution is to not use a regex here. I could use a simple part.split(":") instead.
2. I should look into why HttpRequest is being loaded at macro time - other than causing errors like this, I imagine it would slow down compilation.

I'll give option (1) a go and let you know how it goes...

Hi @npretto,

Would you be able to:

1. Git pull (or re-clone) ufront/hello
2. Make sure the current ufront versions are in use
3. Use the Git version of ufront-mvc, and see if the problem is solved for you. haxelib git ufront-mvc https://github.com/ufront/ufront-mvc.git
4. Recompile and see if the error is gone?

[npretto]

this is really weird...

it works fine on travis-ci though (see PR)

[jasononeil]

Hey @npretto, did you have any luck? Given that Travis is working it seems almost certainly to be an installation issue.

If not, I would like to try get a reproducible sample... it would be interesting to know if something like this fails for you:

package test;
class Test {
    static function main() {
         // Import the package into the macro context
         CompileTime.includePackage("test");
    }
    static var UCWORDSWS = ~/\s[a-z]/g;
}

Looking at your stack-traces I'm guessing the two key factors in reproducing it are:

• Some use of CompileTime.importPackage()
• Static variables with regular expressions in them.

If we could get a reproducible sample (and the stack trace from that sample) we could ask the mailing list to help diagnose it...

[npretto]

Sorry for the late reply!
I can't get it to work on ubuntu (it doesn't find the compiletime haxelib and i have no idea why, i usually don't use linux at all)
It compiles under windows, i tried the hello project again but it can't find the ufront.mailer.TestMailer class (the signup api needs it)

edit: the server actually runs, the problem only occurs on the test.hxml file, i can't properly test it at runtime because i don't have mysql installed but it would probably work if i had!

[jasononeil]

Whoops, I had updated the hello repository without updating the ufront dependencies, sorry.

On the positive side, I now have written some unit tests:

https://github.com/ufront/hello/blob/master/test/src/app/controller/HomeControllerTest.hx#L44

And they pass on travis:

https://travis-ci.org/ufront/hello/builds/50718752#L1727

The unit tests are using sqlite as opposed to mysql. It would probably be easy enough to do the same on the server. The reason I haven't yet, is that I'm having issues with PHP on Haxe 3.1.3 and SQLite. Once Haxe 3.2 is released (if ever) I'll probably change this to use SQLite by defualt...
