Managing CPAN Dependencies Friday, October 14, 2011
Case Study: (Poor) Web Development Friday, October 14, 2011
You’re writing a new web app. You don’t wanna reinvent
wheels. Want to use as many CPAN deps. Friday, October 14, 2011
Fine. Get them from CPAN, install on your machine. Friday,
October 14, 2011
> 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 Friday, October 14, 2011
Test it... Friday, October 14, 2011
Works? Ship it! Friday, October 14, 2011
Deployment Set up new production servers. Install CPAN modules (until
the errors are gone) Friday, October 14, 2011
Few weeks later... Friday, October 14, 2011
Your website is popular! Need more web servers! Friday, October
14, 2011
Re-Deployment Set up new production servers. Install CPAN modules (until
the errors are gone) Friday, October 14, 2011
“Crap, Web::Framework has been updated to 1.4 and many APIs
have been changed or deprecated!” Friday, October 14, 2011
Rollback Log in to the old web server. Check Perl
module versions. Install them on the new server. Friday, October 14, 2011
“Crap, this author deleted the version 1.20 we want. Let’s
go to BackPAN...” Friday, October 14, 2011
“Crap, version 1.20 doesn’t actually work with the newer LWP
6 that we just installed! Have to downgrade this too...” Friday, October 14, 2011
and so on. Friday, October 14, 2011
What was wrong? Friday, October 14, 2011
• Dependency declaration • Isolated Perl environments • Version controls/history
• Dependency analysis • Repeatable deployments • etc. Friday, October 14, 2011
Many existing solutions MyCPAN, DPAN, CPAN::Mini::Inject, OrePAN, Shipwright Friday, October
14, 2011
None of those didn’t quite work for me. (Or I
haven’t even tried) Friday, October 14, 2011
So I wrote a new one. Friday, October 14, 2011
Carton https://github.com/miyagawa/carton Friday, October 14, 2011
Inspired by... Friday, October 14, 2011
Friday, October 14, 2011
• 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 Friday, October 14, 2011
Local perl environment Using local::lib and cpanm -L Each app
has an isolated local library path Friday, October 14, 2011
Fast and safe install cpanm 1.5 Saves MYMETA.json and install
meta info Friday, October 14, 2011
Dep tree analysis Rebuild the dependency tree from meta info
Checks if anything is missing/superflous Friday, October 14, 2011
Locking versions Versions are saved in carton.lock including dependencies Friday,
October 14, 2011
Easy Redeployment Reinstall exactly the same set of modules on
another prod/development machines. Friday, October 14, 2011
Single-file, VCS friendly You can add carton.lock to git update
whenever you update modules Friday, October 14, 2011
Safe and easy rollback revert the lock file and redeploy
