[jira] [Commented] (THRIFT-4069) Perl packages should be in individual files and have proper version syntax

James E. King, III commented on THRIFT-4069:
--------------------------------------------

I sent an email to gslin who originated the perl packages on cpan for the project and asked for any insight he can add here.
Target for these changes is in 0.11.0.

> Currently our perl package module files contain multiple packages.  We should break each package out to an individual file and properly version it.  Package versioning was introduced in Perl 5.10 so:
> 1. Update the minimum required perl to 5.10.
> 2. For each package use the {{perl MODULE VERSION}} perlmod syntax, where VERSION is {{v0.11.0}}.
> 3. Each module not under the Thrift namespace must be moved there.  This will be a breaking change.
> Currently if you inspect the Perl PAUSE version metadata for Thrift's sub-modules only the 0.9.0 modules from gslin have version identities.
> For example if you look at Thrift and Thrift::BinaryProtocol in the CPAN list of packages at http://www.cpan.org/modules/02packages.details.txt you will see:
> {noformat}
> Thrift                         0.010000  J/JK/JKING/thrift/Thrift-0.10.0.tar.gz
> Thrift::BinaryProtocol         0.009000  G/GS/GSLIN/Thrift-0.9.0.tar.gz
> {noformat}
> There are some anomalies, for example packages defined in Thrift.pm come out at the top level namespace like:
> {noformat}
> TApplicationException          0.010000  J/JK/JKING/thrift/Thrift-0.10.0.tar.gz
> TMessageType                   0.010000  J/JK/JKING/thrift/Thrift-0.10.0.tar.gz
> TType                          0.010000  J/JK/JKING/thrift/Thrift-0.10.0.tar.gz
> {noformat}
> So technically if you do 'install TApplicationException' I would expect you might get thrift.  This is wrong and should be fixed.  TApplicationException needs to be inside Thrift, not at the top level.
