I've been wondering if I can make mutexes much easier to use in C++ with creative use of a locking class and variable scope, but I'm not sure if things happen in the order I want. Here's pseudocode for something that could use the class:
int someclass::getvalue()
{
int retval;

Hi,
I am stuck while developing a shell sub-routine which checks the log file for "success" or "failure". The subroutine reads the log file and checks for key word "success", if found it set the variable (found=1). It returns success or failure based on this variable.
My problem is, I can... (2 Replies)

Hi All,
I've been researching this problem and I am pretty sure that the issue is related to the while loop and the piping. There are plenty of other threads about this issue that recommend removing the pipe and using redirection. However, I haven't been able to get it working using the ssh and... (1 Reply)

tap::parser::sourcehandler::perl
TAP::Parser::SourceHandler::Perl(3pm) Perl Programmers Reference Guide TAP::Parser::SourceHandler::Perl(3pm)NAME
TAP::Parser::SourceHandler::Perl - Stream TAP from a Perl executable
VERSION
Version 3.26
SYNOPSIS
use TAP::Parser::Source;
use TAP::Parser::SourceHandler::Perl;
my $source = TAP::Parser::Source->new->raw( 'script.pl' );
$source->assemble_meta;
my $class = 'TAP::Parser::SourceHandler::Perl';
my $vote = $class->can_handle( $source );
my $iter = $class->make_iterator( $source );
DESCRIPTION
This is a Perl TAP::Parser::SourceHandler - it has 2 jobs:
1. Figure out if the TAP::Parser::Source it's given is actually a Perl script ("can_handle").
2. Creates an iterator for Perl sources ("make_iterator").
Unless you're writing a plugin or subclassing TAP::Parser, you probably won't need to use this module directly.
METHODS
Class Methods
"can_handle"
my $vote = $class->can_handle( $source );
Only votes if $source looks like a file. Casts the following votes:
0.9 if it has a shebang ala "#!...perl"
0.75 if it has any shebang
0.8 if it's a .t file
0.9 if it's a .pl file
0.75 if it's in a 't' directory
0.25 by default (backwards compat)
"make_iterator"
my $iterator = $class->make_iterator( $source );
Constructs & returns a new TAP::Parser::Iterator::Process for the source. Assumes "$source->raw" contains a reference to the perl script.
"croak"s if the file could not be found.
The command to run is built as follows:
$perl @switches $perl_script @test_args
The perl command to use is determined by "get_perl". The command generated is guaranteed to preserve:
PERL5LIB
PERL5OPT
Taint Mode, if set in the script's shebang
Note: the command generated will not respect any shebang line defined in your Perl script. This is only a problem if you have compiled a
custom version of Perl or if you want to use a specific version of Perl for one test and a different version for another, for example:
#!/path/to/a/custom_perl --some --args
#!/usr/local/perl-5.6/bin/perl -w
Currently you need to write a plugin to get around this.
"get_taint"
Decode any taint switches from a Perl shebang line.
# $taint will be 't'
my $taint = TAP::Parser::SourceHandler::Perl->get_taint( '#!/usr/bin/perl -t' );
# $untaint will be undefined
my $untaint = TAP::Parser::SourceHandler::Perl->get_taint( '#!/usr/bin/perl' );
"get_perl"
Gets the version of Perl currently running the test suite.
SUBCLASSING
Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.
Example
package MyPerlSourceHandler;
use strict;
use vars '@ISA';
use TAP::Parser::SourceHandler::Perl;
@ISA = qw( TAP::Parser::SourceHandler::Perl );
# use the version of perl from the shebang line in the test file
sub get_perl {
my $self = shift;
if (my $shebang = $self->shebang( $self->{file} )) {
$shebang =~ /^#!(.*perl.*?)(?:(?:s)|(?:$))/;
return $1 if $1;
}
return $self->SUPER::get_perl(@_);
}
