Fix travis timeout

[LLFourn]

docs build sometimes takes so long travis times out. IMO: The solution that involves the least work is to use rakudo binaries rather than building rakudo before building to docs.

Can you confirm the distro Travis runs on? And which version.

Depending on the distro, different options are available to give rakudos for Travis to eat.

Operating System Details
Distributor ID:	Ubuntu
Description:	Ubuntu 12.04.5 LTS
Release:	12.04
Codename:	precise

It looks like we've specified it be 12.04. We can probably change it. It's specified here:

https://travis-ci.org/perl6/doc/jobs/244777120/config

[rafaelschipiura]

Ubuntu 12.04 reached end-of-life in April 28.

It's a very good idea to choose a more recent version.

[LLFourn]

It looks like it's some kind of limitation of travis itself 😞

You can use trusty but it's still in beta: https://docs.travis-ci.com/user/trusty-ci-environment/

Note that if you want the most recent rakudo, then I can expose whateverable builds in some way so that it will be possible to just pull any version you want at any time. Just ping me if this is needed.

[LLFourn]

@AlexDaniel sounds good to me. I guess the process would be:

1. download/extract latest whateverable build
2. install zef and depends
3. run docs build

• recent binaries are a useful thing to have generally.

There's also this rakudo docker container that is only 500megs and takes very little to run (compared to compiling) :-)

[LLFourn]

@JJ that might be the way to go because then we can have zef in the docker image too. FYI you can reduce the size by rm -r the rakudo src directory. I have been doing some work in the same direction as you recently and managed to get a 33mb alpine-based rakudo docker image.

[JJ]

I'll do that in the next release, with the updated rakudo. I was actually wondering what I could safely remove to reduce size. Thanks!

[samcv]

I have already setup travis to archive rakudo, and build files so just get it to build the latest release instead of building a nightly maybe. It backs up many of the build files, though it likely could be optimized. Maybe more folders need to be added to be archived and restored on the next build.

Also I have nightly appimages that build as well if anybody wants to try with that:

The appimages are only 7 MB

[probonopd]

@samcv great work. Minor nitpick: It's not good practice to store AppImages (or any other binaries) in git repositories. There's GitHub Releases for that, check it out.

[LLFourn]

@samcv So we can close this ticket. Or does it still timeout sometimes when it has to re-cache?

[AlexDaniel]

Given that nobody is complaining, I'll close this. If there's still an issue, let's open a new ticket and link this one.
