This post shows how the third party extensions get listed in the installed_extensions.php file as version => '-' , whereas, it is listed as blank elsewhere so that the "Install Extension" icon in the extensions listing gets enabled. This happens at the end of includes/packages.inc:
/*
Check basic extension source compatibility.
*/
function check_src_ext_version($ext_v)
{
global $src_version;
$compat_levels = 2; // current policy is keeping compatibility on major version level.
$app = explode('.', substr($src_version, 0, strspn($src_version, "0123456789.")));
$pkg = explode('.', substr($ext_v, 0, strspn($ext_v, "0123456789.")));
for ($i=0; $i < min($compat_levels, count($app)); $i++)
if ($pkg[$i] < $app[$i])
return false;
return true;
}which should now be corrected to be effective only when it is not a third party extension like:
/*
Check basic extension source compatibility.
*/
function check_src_ext_version($ext_v)
{
global $src_version;
if ($ext_v != '-') {
$compat_levels = 2; // current policy is keeping compatibility on major version level.
$app = explode('.', substr($src_version, 0, strspn($src_version, "0123456789.")));
$pkg = explode('.', substr($ext_v, 0, strspn($ext_v, "0123456789.")));
for ($i=0; $i < min($compat_levels, count($app)); $i++)
if ($pkg[$i] < $app[$i])
return false;
}
return true;
}The logic to display the "Install extension" button/icon should be altered to read from a _init/config file if present in the third party module folder itself thereby populating the version and name fields as well instead of being "-" and folder name respectively as obtains now.
Currently the presence of a Version in the _init/config file in the official packages is provided to the available parameter on install when extracted using the function get_extensions_list() defined in includes/packages.inc.
@joe: kindly incorporate the fix listed here for a start so that third party installs do not get broken and / or resorting to use kludgy workarounds.
