This is a fix for ticket #7670. Some hosting situations don't
allow write access to the system temp path. tiny_mce_gzip.php is currently
using sys_get_temp_dir() by default, and not using a local silverstripe-cache
folder that may exist in the SilverStripe project.
This change moves the getTempFolder() function into a common file, and
includes that in core/Core.php, as well as thirdparty/tinymce/tiny_mce_gzip.php
so both locations share the same code to work out the temp path.
In the case of errors arising during setUp or setUpOnce a unit test will fail to run any individual tests. However, this situation was incorrectly being reported as a test pass (as no tests were run, thus no tests had errors). E.g. the output of a test run that raised an error during setUp would be "0 tests run: 0 passes, 0 failures, and 0 incomplete" with a green background.
To rectify this the following fixes were made:
- Non-cleanly ended tests and test suites are now automatically ended at the end of the test run, as well as at the beginning of subsequent test/suites. This should make catching of errors a lot more robust.
- Errors raised during setup are now no longer lost to the mist of time. The test suite itself will record any error status which was generated outside the scope of any individual tests.
- An additional "errors" count is added to the output at the end of test running. For example, in the case where setup failed and no tests could be run the error would be written to the browser (along with stacktrace) with a message similar to "0 tests run: 0 passes, 0 failures, and 0 incomplete with 1 errors". The intent of this is to separate the concepts of failed/succeeded/incomplete tests from any errors which may have arisen. I.e. no tests "failed" due to the error, but the test run itself is highlighted as an error (red background on the output).
This problem has been a severe cause of issue when testing code that interacts with the database, as any database error during setup would refuse to be shown.
The issue was raised in #7628, where an anchor tag was being changed from
<a name="anchor"></a> to <a name="anchor"/> by SS_HTMLValue, when
HtmlEditorField::saveInto() parses the HTML fragments.
This is because SS_HTMLValue uses DOMDocument::saveXML(), which is fine
for saving an XML document, but not suitable for HTML. This fix changes
that to use DOMDocument::saveHTML() instead.
Note that we can't use the parameter to saveHTML() for selecting a single
node only, as that's only supported in PHP 5.3.6+, SilverStripe 3.0 supports
PHP 5.3.2 as a minimum. The workaround for this shortcoming is to replace
unncessary output by DOMDocument with a regular expression.
In some places source is referenced directly and assumed to be array, while in some places the getSource() method is used instead.
By changing this you have more freedom when extending these classes
