• ZendHQ GUI 1.5.7

    Changed

    • The application log was moved from the app directory to the temporary directory, for example, /tmp/ZendHQ/zendhq-ui.log
    • Fixed logging in case system temp directory is unknown
    • Updated the AgGrid component to version 32

  • ZendHQ GUI 1.5.5

    Fixed

    • Fixes issues on Windows where the application would not close.

  • ZendHQ GUI 1.5.4

    Fixed

    • Fixes date and time validation when creating a new job.

  • ZendHQ GUI 1.5.3

    Changed

    • Connect to ZendHQ using ws:// or wss:// url

    Fixed

    • Failed connection issues

  • ZendHQ 1.7.0

    New Features

    • Added LDAP authentication and authorization support to the ZendHQ daemon.

      ZendHQ daemon can now be configured to use a LDAP server, like ActiveDirectory or an OpenLDAP server, to authenticate and authorize ZendHQ users.

      LDAP authentication is performed asynchronously and JsonRpc clients cannot send other requests before authentication is finished and a response sent to the client.

    • Added Z-Ray SQL queries support for the PHP sqlsrv extension.

      Support for the sqlsrv extension was already added in the previous 1.6.0 version, but now it is enabled for the public use.

    Changes

    • The ZendHQ PHP extension's zeromq PUB/SUB socket endpoint is now configurable

      The zendhq.daemon_pub_uri ZendHQ PHP extension's directive can now be used to set the daemon's zeromq PUB/SUB socket uri manually. The default is to leave this directive undefined and use the uri provided by the daemon.

    • The Z-Ray token cookie max-age attribute is now configurable

      When Z-Ray is requested using the zraytok request parameter, then the ZendHQ PHP extension responds with the Set-Cookie: zraytok= max-age= response header. Consequent requests with the zraytok cookie will trigger additional Z-Ray requests without providing the zraytok request parameter.

      The value of the max-age attribute of the cookie is now configurable in the ini file and can be set to the number of seconds before the cookie expires.

      Setting this value to a value = 0 disables setting the zraytok cookie.

      Default value is 60 seconds.

    • Optimized ZendHQ PHP extension tracing functionality

      Now the ZendHQ PHP extension becomes globally disabled if all the individual tracing functions (like Z-Ray, Monitoring and Code Tracing) are disabled.

      It is still possible to use the Job Queue PHP API.

    • Optimized Code Tracing in the ZendHQ PHP extension.

      Code Tracing is now active only when requested manually or when at least one monitoring rule requires it. If Code Tracing is not requested or there are no monitoring rules with a Code Trace action, then Code Tracing stays inactive in order to improve PHP performance.

    Bug Fixes

    • Fixed a bug in the ZendHQ PHP extension that prevented Apache2 to reload.

      ZendHQ PHP extension has a limited number of global resources. The number of in-use resources was not reset when the PHP extension was re-initialized.

      In addition, a bug in zeromq caused worker processes to hang indefinitely in MSHUTDOWN.

    PHP 7.1 built-in executables (Windows only)

    • The PHP 7.1 built-in executables require the Visual C++ Redistributable for Visual Studio 2015 (x86 variant) to be installed in the operating system. The installer of Zend Studio 13 and later installs it automatically, but users upgrading from earlier Zend Studio version must install it manually from here: https://www.microsoft.com/en-us/download/details.aspx?id=51682

    Apigility integration requirements

    • Internet Explorer >=10 is required on Windows for the Apigility Editor to render correctly.

    Code Trace requirements

    • Flash Player must be installed in the operating system.

    Known Issues

    • Update to Zend Studio 13 or newer from older versions is not supported on Mac OS X. New installation of Zend Studio 13 or newer is required. If an update is attempted, this will corrupt the Zend Studio installation.

    • During update of Studio a security warning about unsigned content may be shown. You can safely ignore this warning and proceed with the upgrade.

    • Z-Ray may not render correctly inside Zend Studio on Windows. A workaround can be applied in one of the following alternative ways:

      • Modify Zend Server configuration to include the "X-UA-Compatible: IE=edge" HTTP header in the response. If Zend Server is running on Apache HTTP Server then:

        • Add the following line in the httpd.conf file:

          Header add X-UA-Compatible "IE=edge"

        • Restart the Apache HTTP Server.

        • Reopen the web browser inside Zend Studio.

      • Modify the application to include "X-UA-Compatible: IE=edge" HTTP header in the response:

        • Add the following line in a suitable place in your PHP code:

          header("X-UA-Compatible: IE=edge");

        • Reopen the web browser inside Zend Studio.

      In Zend Server 8 and later Z-Ray will automatically add the "X-UA-Compatible: IE=edge" HTTP header in the response, so the above workaround will not be required.

    • Zend Debugger PHP extension is not available for PHP builds with Thread Safety enabled. You can find out the status of Thread Safety in your PHP:

      • in phpinfo() output
      • by checking the value of the predefined constant PHP_ZTS ("false" means Non Thread Safe, i.e. supported by Zend Debugger)

      If you use Thread-Safe PHP, consider Xdebug as the alternative.

    • Zend Studio Crashes with Segmentation Fault in KDE 4.11 and newer, see http://kb.zend.com/zend-studio-crashes-with-segmentation-fault-in-kde-4-11

    • Zend Studio menus do not show or appear only partially in the menu bar of Ubuntu 13.10 and 14.04. The issue is caused by Ubuntu's bug https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/1208019. See http://kb.zend.com/zend-studio-menu-does-not-work-on-ubuntu-13-10/

      In Zend Server 8 and later Z-Ray will automatically add the "X-UA-Compatible: IE=edge" HTTP header in the response, so the above workaround will not be required.
