Re: [PHP-DEV] In a destructor, how to detect if an exception is currently in flight?

Thanks for your input. I did not try-catch because it doesn't really work, you either duplicate rollback code or get excessive nesting. Real code will obviously be more complicated than the examples. Also in both cases the handlers are many lines apart from the actual transaction call. Duplicate

[PHP-DEV] In a destructor, how to detect if an exception is currently in flight?

Subject says it all. I want to make a small "ScopeGuard" library for exception-safe transactions, like the following: $scope = new ScopeGuard; $scope->onSucces(function() { logTransactionOne(); }); $scope->onFailure(function() { rollbackTransationOne(); }); doTransactionOne();

[PHP-DEV] Re: Debugings another Drupal PHP 7 failure

wrapping the service container code that is triggering this bug with gc_disable() and gc_enable() or calling gc_collect_cycles() before its run seems to "fix" the segfault which seems to suggests a garbage collection problem. On Wed, Oct 28, 2015 at 12:13 PM James Gilliland

[PHP-DEV] API to retrieve opcode operand and extended_value meaning

Hi, Please review the PR (for master only). It adds an API call to get information about opcode operand and extended_value meaning. This API should be useful for phpdbg, xdebug and others. Once these extension switch to new API, they will support most new opcodes out of the box.
