DuckPAN 0.160 is totalled on Debian/Perl 5.14

[mintsoft]

Yo's;

This has appeared and now my DuckPAN won't run!

[NOTICE] perl v5.16.0 or higher is recommended. v5.14.2 is installed.

@mwmiller @jagtalon @moollaza

[moollaza]

ouch. Sorry @mintsoft. What command did you run?

[moollaza]

and in what directory?

[mintsoft]

both duckpan query and duckpan server do this

[mintsoft]

in the root of my hiragana goodie

rob@set $ duckpan query

[moollaza]

Hmm it's odd that this just started, my last release was like a week ago...did you just update?

[mintsoft]

Yeah I just did an update and boom

[moollaza]

Awesome I have 5.14 on Codio, will investigate...

[mintsoft]

Just ping me if you need any more info

[moollaza]

Hmm @mintsoft I can't get the error to occur. I'm using 5.14 on Ubuntu 3-13. I get the notice, but then it goes on to work just fine. It must be related to your directories. The error is complaining about a directory not existing..

[mwmiller]

@mintsoft Could you check your Path::Tiny version?

perl -le 'eval "require $ARGV[0]" and print $ARGV[0]->VERSION' Path::Tiny

I suspect it's less than 0.053? If so, I'll update the dependencies. I started this conversion well after that release, so I didn't even consider this.

[tommytommytommy]

@moollaza @mwmiller @mintsoft I just ran into the same bug after running duckpan upgrade and duckpan start server on my Ubuntu VM. It looks like my version of Path::Tiny is 0.029.

[mwmiller]

@tommytommytommy Sweet, thanks for the extra info. Could you see if cpanm Path::Tiny fixes this?

[tommytommytommy]

@mwmiller Unfortunately, it doesn't seem to...here's the console output:

[mwmiller]

@tommytommytommy Ok, thanks for the update. I'll look into it further.

[mwmiller]

@tommytommytommy From that file path, it looks like you're running 5.16.3... I think this is a DuckPAN initialization problem with its config.

[mintsoft]

sorry @mwmiller I was ZZZ

rob@set $ perl -le 'eval "require $ARGV[0]" and print $ARGV[0]->VERSION' Path::Tiny
0.055

[mwmiller]

@mintsoft No worries. I've still not tracked it down. Imade some changes which seem "ok" but not very likely to resolve it. Any chance you have set DUCKPAN_CACHE_PATH or DUCKPAN_CONFIG_PATH in your environment?

[mwmiller]

Or any chance HOME is set to something weird?

I tried all kinds of permissions, ownership and existence changes to no effect.

[mintsoft]

@mwmiller nope;

[mwmiller]

Also, if either of you would like to checkout and dzil install the mwm/config_updates branch just to confirm that it doesn't help, that'd be nifty. :grin:

[mintsoft]

@mwmiller I'm doing it now, interesteringly enough I was missing

Dist::Zilla::Plugin::PromptIfStale
Dist::Zilla::Plugin::Authority
Dist::Zilla::Plugin::ChangelogFromGit
Dist::Zilla::Plugin::InstallRelease

But they don't seem to have fixed it yet; I'll update you once it's built & installed

[mintsoft]

@mwmiller done; but still broken!

[mwmiller]

No idea what's up. I have a machine around with Ubuntu 12.04 on it and can't reproduce.

[NOTICE] perl v5.16.0 or higher is recommended. v5.14.2 is installed.
Checking for latest App::DuckPAN ... 0.160
Checking for latest DDG Perl package... 0.130

Using the following DDG instant answers:

[mintsoft]

Hmm, I've got a different Wheezy machine and it works on that; however that's using perlbrew

[mwmiller]

@mintsoft It looks like @tommytommytommy is using perlbrew and still having the problem. I still feel like there was some initialization gone wrong somewhere in all of this.. but I've run out of ideas for places to look.

[mwmiller]

I think I finally found it.

@mintsoft Would you mind trying a dzil install with the latest from mwm/config_updates?

I have much more confidence in my solution this time. Let's call it a coin-flip.

[mintsoft]

@mwmiller yes! Fixed! What was the actual problem? I'm guessing it's: https://github.com/duckduckgo/p5-app-duckpan/commit/4407fad5de6bccd0d05226c4c898e0de03109e9f

[tommytommytommy]

@mwmiller @mintsoft I just pulled https://github.com/duckduckgo/p5-app-duckpan/commit/1029bf779fdddf62f83062b97323443d1a5682bf and ran dzil install, and it works for me too! (Took a while for me to install a lot of missing dependencies that are not normally installed with the Ubuntu virtual machine for testing Goodies/Spices?) I am not at all familiar with how changes propagate; out of curiosity, is there one more step that needs to be done for users to get this via duckpan upgrade? I was still getting version 0.160 with that command.

[moollaza]

@tommytommytommy the reason you had to install several dependencies is because they are required for dzil to build and install the duckpan package -- this isn't the normal way for contributors to go about installing Duckpan. Most of the stuff that was installed is required for tests etc (likely they were all Dzil Plugins). We us dzil to build and package duckpan so it can be pushed out to CPAN, where only the essentials for actually running DuckPAN are needed. Once I've merged and released DuckPAN, the version will bump and you will be prompted to update. At that point you'll go back to using/upgrading DuckPAN as usual :)

[tommytommytommy]

@moollaza Ah! Great :) Thanks for the explanation. So much to learn, so much to learn.

[mwmiller]

the version will bump and you will be prompted to update

Actually, you've probably already installed a 0.161 (via dzil install), but not the 0.161. Easiest way to get back on track with the mainstream is duckpan reinstall

[tommytommytommy]

Great, thanks for the heads-up. If worse came to worse during the install, I figured that I could always destroy the VM and restart. But, this seems like a much easier and less drastic measure :-)

[moollaza]

@mwmiller thanks for that, I realized that later that day, meant to correct myself.
