Managing CPAN Dependencies Sunday, April 15, 12
Case Study: Web App Development Sunday, April 15, 12
You’re writing a new web app. You don’t wanna reinvent
wheels. Want to use as many CPAN deps. Sunday, April 15, 12
Fine. Get them from CPAN, install on your machine. Sunday,
April 15, 12
> cpanm Web::Framework installed LWP-‐5.912 installed Plack-‐0.9980 installed Web-‐Framework-‐1.20 >
cpanm JSON::Fast installed JSON-‐Fast-‐1.91 > cpanm MIME::Parser::XS installed MIME-‐Parser-‐XS-‐0.20 Sunday, April 15, 12
Test it... Sunday, April 15, 12
Works? Ship it! Sunday, April 15, 12
Deployment Set up new production servers. Install used CPAN modules
Sunday, April 15, 12
Few weeks later... Sunday, April 15, 12
Your website is popular! Need more web servers! Sunday, April
15, 12
Re-Deployment Set up new production servers. Install CPAN modules. Sunday,
April 15, 12
“Crap, Web::Framework has been updated to 1.4 and many APIs
have been changed or deprecated!” Sunday, April 15, 12
Rollback Log in to the old web server. Check Perl
module versions. Install them on the new server. Sunday, April 15, 12
“Crap, this author deleted the version 1.20 we want. Let’s
go to BackPAN...” Sunday, April 15, 12
“Crap, version 1.20 doesn’t actually work with the newer LWP
6 that we just installed! Have to downgrade this too...” Sunday, April 15, 12
Sunday, April 15, 12
“Upgrading CPAN modules broke my app” Sunday, April 15, 12
What was wrong? Sunday, April 15, 12
• Dependency declaration • Isolated Perl environments • Version controls/history
• Dependency analysis • Repeatable deployments • etc. Sunday, April 15, 12
Many existing solutions MyCPAN, DPAN, CPAN::Mini::Inject, OrePAN, Shipwright Sunday, April
15, 12
None of those didn’t quite work for me. (Or I
haven’t even tried) Sunday, April 15, 12
So I wrote a new one. Sunday, April 15, 12
Carton https://github.com/miyagawa/carton Sunday, April 15, 12
Inspired by... Sunday, April 15, 12
Sunday, April 15, 12
• App-specific local environment • Fast and safe install •
Dep-tree analysis, including versions • Locking module versions • Easy Redeployment • Single-file, VCS friendly • Safe and easy rollback Sunday, April 15, 12
Local perl environment Using local::lib and cpanm -L Each app
has an isolated local library path Sunday, April 15, 12
Fast and safe install cpanm 1.5 Saves MYMETA.json and install
meta info Sunday, April 15, 12
Dep tree analysis Rebuild the dependency tree from meta info
Checks if anything is missing/superfluous Sunday, April 15, 12
Locking versions Versions are saved in carton.lock including dependencies Sunday,
April 15, 12
Easy Redeployment Reinstall exactly the same set of modules on
another prod/development machines. Sunday, April 15, 12
Single-file, VCS friendly You can add carton.lock to git update
whenever you update modules Sunday, April 15, 12
Safe and easy rollback revert the lock file and redeploy
Sunday, April 15, 12
Declaring CPAN dependencies Sunday, April 15, 12
CPAN Distributions: Makefile.PL or Build.PL Sunday, April 15, 12
Carton apps: cpanfile Sunday, April 15, 12
cpanfile Module::Install + CPAN::Meta Sunday, April 15, 12
requires ‘Plack’, 0.99; on ‘develop’ => sub { recommends
‘Devel::Cover’; }; test_requires ‘Test::Warn’; requires ‘Devel::NYTProf’, ‘>= 3.2, < 5’; conflicts ‘MooseX::Declare’, ‘< 0.99’; Sunday, April 15, 12
WHY • Your applications are not CPAN dists. • GitHub
scripts • PaaS • DotCloud • Heroku • Stackato Sunday, April 15, 12
DEMO Sunday, April 15, 12
> cpanm Carton Sunday, April 15, 12
ܯࠂ It is beta software, some features are missing or
not working correctly (yet). Sunday, April 15, 12
TODO / Roadmap • Update specific modules • Make install
and bundle faster • Inject old versions / patched versions • Install from git SHA Sunday, April 15, 12
