Summary	0001366: Cannot start a debugging session on Windows
Description	PHP 7.1.0RC6 with xdebug 2.5.0rc1 under PHPStorm 10 and 2016.3. In PHPStorm, when starting a debugging session, a message "Connection with 'xdebug 2.5.0rc1' was not established" is first displayed with a link to "Validate the installation". Upon validating the installation, the message "Debug extension settings was updated. Please re-run current configuration to use new values." is displayed. Doing so results in the same issue (namely xdebug is never triggered). If I switch to my setup where I use PHP 7.0.12 and xdebug 2.4.1, everything works fine. I've then attempted to use xdebug 2.5.0rc1 with 7.0.12, and at this point it does not work anymore. If I run php 7.0.12 from the command line, I get an error saying "The procedure entry point zend_pass_function could not be located in the dynamic link library php7ts.dll". Then PHP prints out "Failed loading (PATH TO XDEBUG DLL). Interestingly enough, if I set xdebug.default_enable=1 under PHP 7.1.0RC6 with xdebug 2.5.0rc1, then I can see the traces being displayed in the output, which leads me to believe that the extension work semi-properly, except that the remote debugging is more likely the cause issue.
Steps To Reproduce	Setup PHP 7.1.0RC6 under Windows (7?) Set a breakpoint under PHPStorm Start a debugging session under PHPStorm Notice that the breakpoint is not triggered
Additional Information	It might appear to be potentially related with https://bugs.xdebug.org/view.php?id=1361.

Operating System	Windows 7 x64
PHP Version	7.1-dev

tomzx 2016-11-19 20:32 reporter ~0003766	I downloaded Netbeans 8.2 and reproduced the issue mentioned in the additional information section. Thus, I'd say that those two issues present the same symptoms of the same underlying cause. Also similar log messages Log opened at 2016-11-19 20:31:18 I: Connecting to configured address/port: 127.0.0.1:9000. W: Creating socket for '127.0.0.1:9000', WSAPoll: 0. E: Could not connect to client. :-( Log closed at 2016-11-19 20:31:18

derick 2016-11-22 23:26 administrator ~0003775	If you try to make a debug log as is done in http://bugs.xdebug.org/view.php?id=1361, and described at https://xdebug.org/support.php#remote, does it also include the error about WSAPOLL? The error you described with: `If I run php 7.0.12 from the command line, I get an error saying "The procedure entry point zend_pass_function could not be located in the dynamic link library php7ts.dll". Then PHP prints out "Failed loading (PATH TO XDEBUG DLL).` Is because you load an Xdebug version that is compiled for PHP 7.1, with PHP 7.0. So that is expected. cheers, Derick

tomzx 2016-11-23 00:27 reporter ~0003782	@derick I do not get anything else than what was described in note #3766 (so WSAPoll: 0). I've tried disabling all extensions and the problem still persist. I've also rebooted in order to make sure something else wasn't interfering.

derick 2016-11-23 21:17 administrator ~0003787	Can you please provide the output of the log @tomxz? I'd like to see it all, instead of just your summary.

derick 2016-11-23 21:33 administrator ~0003789	Sorry, never mind that question.

derick 2016-12-02 11:52 administrator ~0003868	tomzx, can you try the right DLL from https://xdebug.org/files/xdebug-vc14-latest.tgz, that is likely php_xdebug-master-7.0-vc14-x86_64.dll, but use your judgement If this works, then I will create another RC (RC2), which should have this fixed.

tomzx 2016-12-02 18:03 reporter ~0003872 Last edited: 2016-12-02 18:21	@derick, xdebug appears to attach correctly now under PHP 7.0.13. However, when I hit a breakpoint, it crashes under PHP 7.1.0. The crash is 100% reproducible. However, it is also possible to have xdebug work correctly for other "simpler" scripts. Could you provide me with the .pdb file for php_xdebug-master-7.1-vc14-x86_64.dll (or all of the .dll .pdb) so that I may give you a better callstack? Otherwise, I've uploaded https://fkcd.ca/iTb/php-xdebug.dmp which is the dump file I generated when it crashed. Would you prefer I create a new issue as it does not appear to be related to attaching xdebug to an IDE anymore? Let me know if you need anything else. -----Exception----- Unhandled exception thrown: read access violation. ht was 0x1.

derick 2016-12-02 23:18 administrator ~0003873	tomzx - please do not use a bug report for other issues than the originally reported one. In this case, this was also reported as https://bugs.xdebug.org/view.php?id=1373, and which I fixed earlier today. I have not yet rebuilt the Windows DLLs. I will close this issue, as you've confirmed Xdebug correctly attaches now.
