add test for bug #70700 (LOB read loop ends early for multibyte strings) #1569
Conversation
|
I think it's somewhat plausible that this bug behavior here could be the root cause behind the bug#60994 (#1566). |
|
@cjbj please can we get some feedback ? |

@ashnazg See the updates in https://bugs.php.net/bug.php?id=70700 about why the testcase is not correct. |

Since bug #70700 is not a code bug perhaps the title should just say 'Tests for LOBS with multibyte strings'?

Is that dot supposed to be there? =.

Yes the dot should be there. It is the separator from the language & territory component. In this case the language & territory are empty meaning the defaults are used. Other examples exist in PHP tests: http://lxr.php.net/xref/PHP-MASTER/ext/oci8/tests/bug47281.phpt#17

The repeat time should be 1000000 to match the expected result.

@cjbj can we get another review here please ? |

Please add the following check here:
if (!extension_loaded('mbstring')) die('skip mbstring is not enabled');
After adding this, we're good to go.

Comment on behalf of sixd at php.net: Merged - thanks! |
Tests to show bug behavior of "LOB read loop ends early for multibyte strings", as described in https://bugs.php.net/bug.php?id=70700.
Additional notes are on my question here (http://stackoverflow.com/questions/33026617/pdo-oci-truncates-large-multibyte-clobs) that might help diagnose the bug.
@cjbj: I had to construct this PHPT by hand from my standalone PHP test file, so it may need some polishing to run just right with your test scaffolding (those require targets etc). I'll update PR if you'll highlight any edits that are needed to get it running.
