Stack Overflow about html5validator

That must be quite the webpage! Perhaps trim it down a bit, too? ;)

@DanielOaks Thanks for bringing this up. I had not seen this problem. I like the idea of making it a command line option.

[DanielOaks]

I can imagine something like a -b option (big) that doubles the memory size each time it's added, maybe something like: html5validator -bb doubling it from 512 to 1024, then from 1024 to 2048? Similar to how multiple levels of verbosity/debugging flags work in some programs.

Otherwise just a simple way of specifying the size manually, --size 2048k or something simple like that?

@Supuhstar Unfortunately, pages describing technical data can get pretty big :)

[svenkreiss]

I like the -b, -bb, -bbb approach. Nobody knows in any case which file size corresponds to which stack size. Makes this feature more accessible.

How I can workaround this? How to specify the stack size?

@php-coder Interesting. Is this on Windows?

I was under the impression that specifying '-Xss512k' would always increase the stack size (from 128k or 320k). For you however it seems to increase when you remove it. I am not sure, but I found some reference online that on Windows the default is actually 1024k.

@svenkreiss No, it's on Fedora 22 with OpenJDK 1.8.0_60

[php-coder]

It also fail in TravisCI with the same error :-( Probably, it's because I still use old build type...

[svenkreiss]

Working on this. The 0.2 branch contains a fix for this. It contains the new command line options -l, -ll and -lll which increase the stack size. It also contains an update of the underlying Java checker. Unfortunately, that now requires Java 8. I updated the readme in the 0.2 branch with instructions.

Any volunteers to test this branch? Unit tests are passing.
I think you can install this branch directly with pip install https://github.com/svenkreiss/html5validator/zipball/0.2.

[php-coder]

I'll try it when I will have a time..

[svenkreiss]

Thank you all!

Version 0.2.1 is now released and should address this. If it does not work out of the box for you, try the new command line options -l, -ll and -lll. Please reopen this issue if you see any problems.

[php-coder]

When I'm trying new version it works without any options. I don't know why...

Thank you!

[svenkreiss]

The default in the new version is not to have an -Xss option when calling Java. Like in your diff a few days ago ;)
Thanks!
