perl - Method name conflicts in Moose roles -


what achieve create moose class imports several roles. i've been doing years no issues, though stuck on why simple example below generate method name conflicts.

package logrole;  use moose::role; use posix; use namespace::autoclean;  package otherrole;  use moose::role; use file::temp; use namespace::autoclean;  package myclass;  use moose; use namespace::autoclean; 'logrole', 'otherrole';   package main;  use strict; use warnings; use myclass;

running gives:

due method name conflicts in roles 'logrole' , 'otherrole', methods 'seek_cur', 'seek_end', , 'seek_set' must implemented or excluded 'myclass' @ /home/user/perl5/perlbrew/perls/perl-5.22.1/lib/site_perl/5.22.1/x86_64-linux/moose/exporter.pm line 419 moose::with('logrole', 'otherrole') called @ roles.pl line 29

according docs can exclude method names when consuming role so:

package logrole;  use moose::role; use posix; use namespace::autoclean;  package otherrole;  use moose::role; use file::temp; use namespace::autoclean;  package myclass;  use moose; use namespace::autoclean; 'logrole', 'otherrole' => { -excludes => ["seek_cur", "seek_end", "seek_set" ] };  package main;  use strict; use warnings; use myclass;

this solves name conflicts, problem solution trying import posix in otherrole generates hundreds of name conflicts, fix of excluding these in module myclass seems messy.

how can import (or write) these roles avoid method name conflicts?

namespace::autoclean doesn't remove methods, , trusts class::mop::class's get_method_list return them. confusingly, returns constants posix module.

if switch namespace::autoclean namespace::clean, problems gone.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
