Perforce Python Script Collection.

by scmgalaxy KPythonLeave a Comment on Perforce Python Script Collection.

rajeshkumar created the topic: Perforce Python Script Collection.

Implement a script that will do following:

1. Read config file. This file will contain following settings:
a. For mail delivery (SMTP)
b. For access to perforce server
2. Get from perforce a list of changes made since last script run time and get all updated files
3. Invoke script that will ‘build’ the changes – it will be located in the working folder of the
script(build.bat/build.sh). Script itself should come from perforce as well during step 2.
4. If running of build script is successful, add/update contents of folder named ‘bin’ in the perforce
repository (it is expected that build script will put there a product of its work)
5. In case of error of invocation, send out an email with the list of changes retrieved in p.2 and all outputs of
build script (both stdout/stderr), in which case contents of ‘bin’ folder should not be updated to perforce

Solution
Script details:
master.py – This file is the main file which should be excuted to get the all desired output as per the task
build.bat – This is a Build file which will be executing during compilation phase in master.py. config.ini: Following key should be modified as the environment specification

Sender
Receivers
Message
Host
p4port
p4user
p4client
p4passwd
Scenario to create fail Build:
Remove comment line from “REM mkdir raj” in build.bat

How to use?
Change the config.ini file appropriately and fire master.py script. If you find any issues, please follow the log error message accordingly.

I used to do in shell using following command

Correct me if I am wrong

venu.madhav48@gmail.com replied the topic: Re:i need to a perl script

Please answer the below questions

1.What standard Perl modules have you made use of, and why did you use them instead of the equivalent built-in functions?

2.Write a statement that checks to make sure there are at least two command line arguments and exits with an error if not.

3.How do you find the number of elements in an array?

4.When an array is defined, PERL automatically numbers each element in the array
beginning with zero

The difference between my and local

by scmgalaxy KPerl ScriptLeave a Comment on The difference between my and local

rajeshkumar created the topic: The difference between my and local

There is a subtle difference.

In the example below, $::a refers to $a in the ‘global’ namespace.
‘local’ temporarily changes the value of the variable, but only within the scope it exists in.
$a = 3.14159;
{
local $a = 3;
print “In block, \$a = $a\n”;
print “In block, \$::a = $::a\n”;
}

print “Outside block, \$a = $a\n”;
print “Outside block, \$::a = $::a\n”;

# This outputs In block,

# This outputs
In block, $a = 3
In block, $::a = 3
Outside block, $a = 3.14159
Outside block, $::a = 3.14159

‘my’ has no effect on the global $a, even inside the block.

$a = 3.14159;
{
my $a = 3;
print “In block, \$a = $a\n”;
print “In block, \$::a = $::a\n”;
}
print “Outside block, \$a = $a\n”;
print “Outside block, \$::a = $::a\n”;

# This outputs
In block, $a = 3
In block, $::a = 3.14159
Outside block, $a = 3.14159
Outside block, $::a = 3.14159

scmuser replied the topic: Re: The difference between my and local

With more explanation…

Both of them are used to declare local variables.
The variables declared with “my” can live only within the block it was defined and cannot get its visibility inherited functions called within that block, but one defined with “local” can live within the block and have its visibility in the functions called within that block.
