Unable to pass global parameters between perl based testcases

[mmajdoubi]

First of all, I wish everybody a healthy a successful 2015

When using Perl, I notice that passing global parameters between testcases does work as expected. when using python the testcases work as expected

I used the following Perl and Python testcases to validate this functionality:

/twister/demo/testsuite-perl

——————————————————————— cat test-set_globals.plx ———————————————————————

!/usr/bin/perl

$g0 = get_global("/TC/1"); print "#######value before set#######get_global value fromt test-case1###### = $g0 ...\n"; set_global('/TC/1', "11"); $g0 = get_global("/TC/1"); print "########value after set#######get_global value fromt test-case1###### = $g0 ...\n"; exit($STATUS_PASS);

——————————————————————— cat test-get_globals.plx ———————————————————————

!/usr/bin/perl

$g0 = get_global("/TC/1"); print "##############get_global value fromt test-case2###### = $g0 ...\n";

/twister/demo/testsuite-python

——————————————————————— cat test-set-globals.py ———————————————————————

Print Level-1 / global1 param

global1 = get_global('/TC/1') print '#########value before set#########python get_global-test value:', global1, '\n' set_global('/TC/1', 11) global1 = get_global('/TC/1') print '#########value after set#########python get_global-test value:', global1, '\n' _RESULT = 'pass'

——————————————————————— cat test-get-globals.py ———————————————————————

Print Level-1 / global1 param

global1 = get_global('/TC/1') print '##################python get_global-test value:', global1, '\n' _RESULT = 'pass'

The result of both scripts are listed below

Could you please check why passing global parameters does take effect when using Perl?

Thanks in advance

Hello, I cannot reproduce this with Perl . This is my code in the first Perl test:

print "\nSetting some globals...\n";

set_global("/TC1/1", "some string");
set_global("/TC1/2",  9999);

$g0 = get_global("/TC1/1");
print "Getting some global 1  =  $g0 ...\n";

$g0 = get_global("/TC1/2");
print "Getting some global 2  =  $g0 ...\n";

And this in the second test:

print "Getting globals from previous glob test.\n";

$g0 = get_global("/TC1/1");
print "Getting some global 1  =  $g0\n";

$g0 = get_global("/TC1/2");
print "Getting some global 2  =  $g0\n";

The output for first test:

~ Perl ~ Compiling Inline::Python ~

Starting test test_globals.plx ...

Setting some globals...
Getting some global 1  =  some string ...
Getting some global 2  =  9999 ...

~ Perl returned code `0` ~

The output for second test:

~ Perl ~ Compiling Inline::Python ~

Starting test test_globals_new.plx ...

Getting globals from previous glob test.
Getting some global 1  =  some string
Getting some global 2  =  9999

~ Perl returned code `0` ~

The globals are kept from one Perl test to another. You could also use then from/ between Python, Perl and TCL because it's the same shared memory, as long as you use numbers and strings.

Hi, I see this is very Strange, I run exactly your scripts and my system was not able to set the global parameters (see below for the output). I also notice a warning in the server_log:

Any other idea? Should I reinstall Twister application ?

[croqaz]

Hi, I don't think you need to reinstall. The CeConfigs.py file hasn't changed for some time so it's up to date. In the applet > configuration > global parameters, do you have the TC1 folder ? In order for the test to work, you need the "TC1" globals folder:

Maybe this is the problem ?

[mmajdoubi]

I reinstall twister completely but it's still not working. see my configuration below:

user@mohamedm-virtual-machine:~/twister/demo/testsuite-perl$ cat test_set_globals.plx
#!/usr/bin/perl
print "setting globals .\n";
set_global("/TC1/1",1111);
set_global("/TC1/2",2222);

$g0 = get_global("/TC1/1");
print "Getting some global 1  =  $g0\n";
$g0 = get_global("/TC1/2");
print "Getting some global 2  =  $g0\n";

user@mohamedm-virtual-machine:~/twister/demo/testsuite-perl$ cat test_get_globals.plx
#!/usr/bin/perl
print "getting globals from previous glob test.\n";
$g0 = get_global("/TC1/1");
print "Getting some global 1  =  $g0\n";
$g0 = get_global("/TC1/2");
print "Getting some global 2  =  $g0\n";

Test results

we do expect value 1111 and 2222 which are set by the previous testcase, unfortunately this not the case :(

any other idea, may is this related be the inline::python version? is there any debug command available for further troubleshooting, this is very strange

thanks in advance

[mmajdoubi]

There must be some difference between my case and your case. Could you please send me you twister project file(s)

Thanks

[mmajdoubi]

I did some troubleshootingl the get_global method in TscCommonLib (method is only applicable to Perl scripts) is not hitting the right part of code. that is why I get the configured global_var in stead of the one that is stored in memory.

I assume that the condition (if var in cls.global_vars) should be TRUE if a global_var is stored in memory? is there any way how to check if the globals variables are stored in memory?

/opt/twister/lib/TscCommonLib.py

 @classmethod
    def get_global(cls, var):
        """
        Function to get variables saved from Test files.
        The same data must be used, both in Testcase and derived Libraries.
        """
        if var in cls.global_vars:
            return cls.global_vars[var]
        #Else:
        ce = cls._ce_proxy()
        return ce.get_global_variable(var)

    @classmethod
    def set_global(cls, var, value):
        """
        Function to keep variables sent from Test files.
        The same data must be used, both in Testcase and derived Libraries.
        """
        try:
            marshal.dumps(value)
            cls._ce_proxy()
            return cls.ce_proxy.set_global_variable(var, value)
        except Exception:
            cls.global_vars[var] = value
            return True
