1.0 SCOPE ^

This paragraph identifies and provides an overview of the released files.

1.1 Identification

This release, identified in 3.2, is a collection of Perl modules that extend the capabilities of the Perl language.

1.2 System overview

One very useful test of the installation of a package is whether or not the package loaded. If it did not load, the reason it did not load is helpful diagnostics and may be used to programically (automatically) take corrective action.

The load_package method attempts to capture any load problems by loading the package with a "require " under an eval and capturing all the "warn" and $@ messages. The error messages are returned with a warn instead of die so that the using program may take the appropriate action such as reporting the errors back to the author when used in test software or perhaps falling back on a system 'gzip' command when the 'Compress::Zlib' module fails to load.

1.3 Document overview.

This document releases File::Package version 0.06 providing a description of the inventory, installation instructions and other information necessary to utilize and track this release.

3.0 VERSION DESCRIPTION ^

Changes to past revisions are as follows:

Test-TestUtil-0.01

Originated

Test-TestUtil-0.02

Correct failure from Josts Smokehouse" <Jost.Krieger+smokeback@ruhr-uni-bochum.de> test run

t/Test/TestUtil/TestUtil....Bareword "fspec_dirs" not allowed while "strict subs" in use at

  /net/sunu991/disc1/.cpanplus/5.8.0/build/Test-TestUtil-0.01/blib/lib/Test/TestUtil.pm line 56.

Changed line 56 from

 my @dirs = (fspec_dirs) ? $from_package->splitdir( $fspec_dirs ) : ();

to

 my @dirs = ($fspec_dirs) ? $from_package->splitdir( $fspec_dirs ) : ();

This error is troublesome since the test passed on my system using Active Perl under Microsoft NT. It should never have passed. This error is in a core method, fspec2fspec, that changes file specifications from one operating system to another operating system. This method has been in service unchanged for some time.

Test-TestUtil-0.03

Correct failure from Josts Smokehouse" <Jost.Krieger+smokeback@ruhr-uni-bochum.de> test run

PERL_DL_NONLAZY=1 /usr/local/perl/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/Test/TestUtil/TestUtil.t t/Test/TestUtil/TestUtil....# Test 18 got: '$VAR1 = ''; ' (t/Test/TestUtil/TestUtil.t at line 540 fail #17) # Expected: '$VAR1 = '\\=head1 Title Page

The pm2datah method is not returning any data for Test 18. This will also cause the test of pm2data, test 19 to fail. The pm2datah is searching for the string "\n__DATA__\n".

The "\n" character on Perl is a logical end of line character sequence. The "\n" end of line is different on Mr. Smokehouse's Unix operating system than on my Windows NT operating system. The test file was created under MSWin32 and uses a MSWin32 "\n". Under UNIX, pm2datah method will look for the Unix "\n" and there will not be any.

Changed "\n__DATA__\n" to /[\012\015]__DATA__/.

During the clean-up for CPAN, broke the format_hash_table method for tables in hash of hash format. Fixed the break, added test 29 to the t/Test/TestUtil/TestUtil.t test script for this feature, and added a discusssion of this feature in POD discription for format_hash_table

Test-TestUtil-0.04

item our old friend visits again - DOS and UNIX text file incompatibility

This impacts other modules. We have to examine all modules for this portability defect and correct any found defects.

Correct failure from Josts Smokehouse" <Jost.Krieger+smokeback@ruhr-uni-bochum.de> and Kingpin <mthurn@carbon> test runs.

On Mr. Smokehouse's run email the got: VAR1 clearly showed extra white space line that is not present in the expected: VAR1. In Mr. Kingpin's run the got: VAR1 and expected: VAR1 look visually the same. However, the Unix found a difference(s) and failed the test.

For Mr. Smokehouse's run:

PERL_DL_NONLAZY=1 /usr/local/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/Test/TestUtil/TestUtil.t t/Test/TestUtil/TestUtil....NOK 18# Test 18 got: '$VAR1 = '\\=head1 Title Page

 Software Version Description


 for


  File::Package - test load a pm and import symbs without eval and $@ misbehavoirs

What we have before, was a totally "failure to communicate." aka Cool Hand Luke. VAR1 was empty. Now VAR1 has something. It is not completely dead. One probable cause is the Unix operating system must be producing two Unix \012 new lines for a Microsoft single newline \015\012. Without being able to examine the test with a debugger, the only way to verify this is to provide the fix and see if the problem goes away when this great group of testers try for the fourth time.

Revised fin method to take a handle, change pm2datah method handle, $fh, to binary by adding a binmode $fh statement, and pass the actual thru the fin method for test 18.

Use fin($fh) to read in the data for pm2data, test 19 Unit Under Test (UUT), instead of using the raw file handle.

The fin method takes any \015\012 combination and changes it into the logical Perl new line, "\n", for the current operating system.

  • At 02:44 AM 6/14/2003 +0200, Max Maischein wrote: A second thing that I would like you to reconsider is the naming of "Test::TestUtil" respectively "Test::Tech" - neither of those is descriptive of what the routines actually do or what the module implements. I would recommend renaming them to something closer to your other modules, maybe "Test::SVDMaker::Util" and "Test::SVDMaker::Tech", as some routines do not seem to be specific to the Test::-suite but rather general (format_array_table). Some parts (the "scrub" routines) might even better live in another module namespace, "Test::Util::ScrubData" or something like that.

    Broke away all the file related methods from Test::TestUtil and created this module File::FileUtil so the module name is more descriptive of the methods within the module.

  • Broke the smart nl code out of the fin method and made it is own separate method, smart_nl method.

    At 02:44 AM 6/14/2003 +0200, Max Maischein wrote: Perl, as Perl already does smart newline handling, (even though with the advent of 5.8 even Unix-people have to learn the word "binmode" now :-))

    The only place where I see Perl does smart newline handling is the crlf IO displine introduce in Perl 5.6. The File::FileUtil has a use 5.001 so that 5.6 Perl built-ins cannot be used. Added comment to smart_nl that for users with 5.6 Perl that it may be better to use the built-in crlf IO discipline.

  • For the load_package method that uses a eval "require $package" to load the package, the $@ does not capture all the warnings and error messages, at least not with ActiveState Perl. Added code the captures also the warnings, by temporaily reassigning $SIG(__WARN__), and added these to the $@ error messages.
  • Added two new tests to verify the NOGO paths for the for the load_package method. One tests for load module failure looking for all the possilbe information on why the module did not load. The other verifies that the vocabulary is present after the loading the module. This information is very helpful when you must remote debug a load failure from CPAN testing whose is running on a different platform.
File-FileUtil-0.02

Added the method hex_dump.

File-FileUtil-0.03
test_lib2inc

Returns to parent directory of the first t directory going up from the test script instead of the t directory.

find_t_roots

Added the function find_t_roots that returns the parent directory of all the directories in @INC

File-Package-0.01

Removed the methods for loading a program module with the same name from the "File::FileUtil" module to their own module "File::Package" module. The module name is now much more descriptive of the routines in the module.

File-Package-0.02

Replace the obsolete "File::FileUtil" with File::Packgage in the test script "t\File\package.t".

File-Package-0.03

Added subroutine interfaces.

Added @import input to load_packages method

File-Package-0.04

Upgraded the 'tlib\Test\Tech' and changed the name of 'tlib\Data\strify' to 'tlib\Data\Secs2'. The new name is more self-explanatory.

File-Package-0.05

The lastest build of Test::STDmaker expects the test library in the same directory as the test script. Coordiated with the lastest Test::STDmaker by moving the test library from tlib to t/File, the same directory as the test script and deleting the test library File::TestPath program module.

File-Package-0.06

Added Carp::longmess, that dumps the call stack, to the Carp::croak trap function.

File-Package-0.07

Expanded the description.

Under the Perl 5.6, Microsoft distribute, Carp program module, import sends warings out using &Carp::carp function as well as Carp::croak function. Adjust to also pick up these messages.
