Compatibility Wrapper seems to not work since 1.7.1

[rodflohr]

Starting with 1.7.1, the Compatibility Wrapper seems to be completely broken. Here is an example script:

<?php
// Test Compatibility Wrapper connection.

// Enable the next line if the XML Toolkit API is not in the include path
//ini_set('include_path', ini_get('include_path') . ":/usr/local/zendsvr/share/ToolkitAPI");

// Bring in the Compatibility Wrapper
require_once 'CW/cw.php';

$user = 'rod';
$password = 'rod';
$server = '127.0.0.1';

$conn = i5_connect($server, $user, $password);

if (!$conn ) die("<br>Connection failed");

echo "<pre>";
echo "<br>================<br>";
echo "connected";
echo "<br>================<br>";

i5_close($conn);

?>

Replace 'user' and 'password' with valid credentials. This script will return a 500 error. Here are the errors in php.log:

I can at least get rid of the undefined constants by including cwclasses.php into cw.php, but there are still other errors. It does not appear to ever have worked, although I am testing on PHP 7.3, so possibly it was OK in PHP 5, although it seems unlikely. Currently it seems the only way I can get Compatibility Wrapper working for my customers is to back them down to 1.6.1.

@rodflohr Try this workaround in your demo script: Underneath your require_once of cw.php, add the line: require_once 'CW/cwclasses.php'; Let us know if that solves the issue.

We will work with @chukShirley on a permanent fix.

[rodflohr]

@alanseiden That seems to work. Interesting that placing that require inside cw.php does not work. Some scoping issue with the objects?

[alanseiden]

@rodflohr We find that placing the classes require inside cw.php does work (at least with the latest on Github) but we didn't want to suggest people changing the toolkit on their own. We'll submit a PR and then tag the latest release.

@alanseiden Works for me in 1.8.3. For some reason I was testing in 1.7.1, where that fix did not seem to work all the way. Thanks for pointing this out.

[alanseiden]

@rodflohr We have fixed this issue in 1.8.4. Please test and let us know if 1.8.4 addresses the issue.
