| Summary | 0001449: Debugging breaks with array element keys containing low-ASCII variable | ||||
| Description | When inspecting a variable that contains an instance of a class that extends \ArrayObject (and only in this case), my IDE hungs and the execution crashes if the instance contains some values. | ||||
| Steps To Reproduce | - Create a composer project that requires "gettext/gettext" : "0000003:0000003.6.1" - Create this PHP file <?php use Gettext\Translations; require_once 'path/to/vendor/autoload.php'; $translations = new Translations(); $translations->insert('context', 'string'); var_dump($translations); - Place a breakpoint at the "var_dump" line - When the breakpoint is hit, try to evaluate the "$translations" variable | ||||

I don't know why the "Steps To Reproduce" reports "gettext/gettext" : "0000003:0000003.6.1" the version is tilde followed by 3.6.1 |
|
|
I'm able to reproduce this bug even with this very simple code: <?php $var = new ArrayObject([]); $var->offsetSet("1\x042", 'x'); var_dump($var); The crash occurs if the index contains chars < 0x20 (like 0x04 in the above example) |

PS: I don't know if it's an xdebug or an Eclipse+PDT bug, so I also filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=519045 |

There are two issues at play here. The first one is that from your log I see that Xdebug doesn't escape the \x04 properly in its XML output, and this is likely why PDT falls over. The second issue is that I don't even *get* there due to a "can not read property" bug that has been cropping up. I do have an idea how to fix that, but it's harder than I thought. I'll amend this ticket to only track the unescaped \x04 though. |

This is now fixed for Xdebug 2.6.0-dev, but, it requires that the IDE sets the "extended_properties" feature (https://xdebug.org/docs-dbgp.php#feature-names). This new feature is supported in 2.6.0dev, through https://bugs.xdebug.org/view.php?id=1312. |
