namespaces - Perl: Setup multiple package names for variable/functions? -

-

first, i'd isn't question of design, question of compliance. i'm aware there issues current setup.

in module, there packages named after servers, has many of same variables/functions pertain server. looks set do:

  • production_server_name::printer() or
    test_server_name::printer()

perhaps better design might have been like:

  • central_package_name::printer('production') or central_package_name::printer('test')

anyhow, seems server names have changed, instead of using actual servernames, i'd rename packages production or test, without changing other code still refering production_server_name.

something like:

package production, production_server_name;  # pseudo code

i'm guessing sort of glob/import might work, wondering if there something similar. realize it's not practice saturate namespaces.

i not providing comments on design or might involve changing client code. functions in mytest.pm can accessed using either mytest:: or myexam::. however, can't use use myexam because physical file not there. clever @inc tricks, programs crash , burn when try clever.

mytest.pm

package mytest;  sub hello { 'hello' } sub twoplustwo { 4 }  $sub (qw( hello twoplustwo)) {     no strict 'refs';     *{"myexam::$sub"} = *{"mytest::$sub"}; }  1;

test.pl

#!/usr/bin/env perl  use strict; use warnings; use feature 'say';  use mytest;  myexam::hello(); myexam::twoplustwo();

output:

hello 4

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
