I'm sorry to bother again, but I cannot find the 'profiling' button. Screenshot from IntelliJ navbar: Screenshot from PyCharm navbar: I'm very sure that I have installed the Python plugin. Profiling is a hard job. Keeping in mind execution time and code structure is a serious challenge with regard to the huge amount of collected information. WebStorm assists you on this tough journey. It starts a Node.js application with profil. JetBrains PhpStorm Keygen Full Torrent Download: JetBrains PhpStorm Crack is an industry-leading (IDE) Integrated Development Environment. It is modern (IDE). It’s an editor for your PHP, code, and all the languages that are front-end. It provides code conclusion, intentions, syntax highlighting & refactoring, inspections, and code quality. PhpStorm is a PHP IDE. It provides on-the-fly error prevention, autocompletion and code refactoring, zero configuration debugging and an extended HTML, CSS, and JavaScript editor. PhpStorm also provides powerful built-in tools for debugging, testing and profiling your applications.

This page gives a basic introduction to debugging MediaWiki software.

Phpstorm Profiling

One of the first things you will notice is that 'echo' generally does not work; this is part of the general design.

PHP errors

To see PHP errors, add this to the second line from the top (right below the <?php) of LocalSettings.php:

Or set it in php.ini:

Or set in .htaccess:

This will cause PHP errors to be shown on-page. This might make it easier for attackers to find a way into your server, so disable it again when you have found the problem.

Note that fatal PHP errors may happen before the lines above are ever executed, or may prevent them from being shown. Fatal PHP errors are usually logged to Apache's error log – check the error_log setting in php.ini (or use phpinfo()).

There are several configuration options to aid debugging. The following are all false by default. Enable them by setting them to true in your LocalSettings.php:

  • $wgShowExceptionDetails Enable more details (like a stack trace) to be shown on the 'Fatal error' page.
  • $wgDebugToolbar Shows a toolbar on the page with profiling, log messages and more.
  • $wgShowDebug Adds the 'log messages' part of wgDebugToolbar as a raw list to the page.
  • $wgDevelopmentWarnings MediaWiki will throw notices for some possible error conditions and for deprecated functions.

Turning display_startup_errors on

Some providers turn display_startup_errors off, which hides the errors even if you raise the error_reporting level. Turning it on within the program is too late! Instead you'll have to create a wrapper file around your file. In the case of MediaWiki you can just add this on top of mediawiki/index.php:

In other environments:

Phpstorm Profiling

SQL errors

To log all SQL queries, rather than just the one that raised the exception, set $wgDebugDumpSql in LocalSettings.php:

MediaWiki versions:
1.16 – 1.31

Prior to MediaWiki 1.32, you needed to set $wgShowSQLErrors and $wgShowDBErrorBacktrace to see details of database exceptions in the HTML output:

In-depth debugging

Phpstorm Profiling

Debugger

For the most common setup (using MediaWiki-Vagrant and PhpStorm) see Manual:How to debug/with MediaWiki-Vagrant and PHPStorm.

Profiling
Zend

If you are using the Zend PHP interpreter, you can debug your code with XDebug. MediaWiki-Vagrant has built in settings for this. If you're not using MediaWiki-Vagrant, but your setup is similar, you can reuse those values. In some cases (e.g. due to a firewall), you may have to use the IDE on the same machine as the web server. In this case, you can simply set:

Phpstorm Profiling Training

See the XDebug documentation for more information.

To debug a command-line script (e.g. PHPUnit, or a maintenance script) on MediaWiki-Vagrant, use:

Adjust the script, parameters, and remote host (it should be the IP of the computer where your IP is, 10.0.2.2 should work for MediaWiki-Vagrant) as needed.

Logging

For much greater detail, you need to profile and log errors.

The instructions below are only valid for the default configuration. If you change $wgMWLoggerDefaultSpi, for example enable the psr3 role on a vagrant box, these settings will probably be ignored. See in this case the documentation of your logger, like Manual:MonologSpi.

Setting up a debug log file

To save errors and debugging information to a log, add $wgDebugLogFile to the LocalSettings.php file. Change the value to a text file where you want to save the debug trace output.

The MediaWiki software must have permissions from your operating system to create and write to this file, for example in a default Ubuntu install it runs as user & group www-data:www-data.Here's a sample setting:

Profiling

This file will contain much debug information from MediaWiki core and extensions.Some subsystems write to custom logs, see #Creating a custom log file to capture their output.

Database transaction lifecycle debugging can be enabled for some databases with $wgDebugDBTransactions.

Warning:The debug log file can contain private information such as login credentials, session cookies, and values of submitted forms. If this information is publicly accessible, attackers can use it to hack and compromise your machine and user account. If you need to share a debug log for diagnostic purposes, access the wiki without being logged in, and remove from the debug log any COOKIE lines, and don't capture any login attempt.


Creating a custom log file

MediaWiki version:
1.31

Prior to MediaWiki 1.32, to create a custom log file that only holds your specific debug statements, use the wfErrorLog() function.This function takes two arguments, the text string to log and the path to the log file:

Creating custom log groups

If you're debugging several different components, it may be useful to direct certain log groups to write to a separate file.See $wgDebugLogGroups for more information.

To set up custom log groups, use the following to LocalSettings.php:

To log to one of these groups, call wfDebugLog like this:

If you have carefully followed the instructions above but nothing gets written to your logging file(s), and if your system is using SELinux, have a look at the logging section on the SELinux page to get around this SELinux context issue.
Writing log files to the /tmp directory may not generate any log file at all, even if the /tmp directory is supposed to be writable by anyone. This could happen if your system is using one of the systemd features that create a virtual /tmp directory for that process. If that's the case, configure your log file to be written into a different directory, like /var/log/mediawiki

Structured logging

Phpstorm Profiling System

MediaWiki version:

Structured logging allows you to include fields in your log records.See Structured logging for more information.

You will need to configure a better logger to collect the extra fields, for example Monolog.

Statistics

Advanced client-side logging can be performed with Extension:EventLogging, which requires a complex setup and careful inspection of privacy issues.

Simple counting of certain kind of events is possible (since MediaWiki 1.25) using StatsD. StatsD offers meters, gauges, counters, and timing metrics.

Usage example:

The metrics can be sent to a StatsD server, which may be specified via the wgStatsdServer configuration variable. (If not set, the metrics are discarded.) You can work with StatsD locally (without needing a Graphite server) by starting a StatsD server and configuring it with the 'backends/console' backend, which will output metrics to the console.

As of MediaWiki 1.25, wfIncrStats() is a shortcut for the increment() method on the main RequestContext::getStats() instance.

Send debug data to an HTML comment in the output

This may occasionally be useful when supporting a non-technical end-user. It's more secure than exposing the debug log file to the web, since the output only contains private data for the current user. But it's not ideal for development use since data is lost on fatal errors and redirects. Use on production sites is not recommended. Debug comments reveal information in page views which could potentially expose security risks.

Working live with MediaWiki objects

eval.php is an interactive script to evaluate and interact with MediaWiki objects and functions in a fully initialized environment.

The MediaWiki-Vagrant portable virtual machine integrates the interactive PHP shell phpsh (when using Zend).

Callable updates

Code embedded in the DeferredUpdates::addCallableUpdate() function, such as $rc->save() in RecentChange.php, is not executed during the web request, so no error message will be displayed if it fails.For debugging, it may be helpful to temporarily remove the code from within the function so that it is executed live.

Client side debugging (JavaScript)

Wikipedia offers a rich set of tools for debugging client side JavaScript.In addition to the MediaWiki tools, other techniques are available to assist with diagnosing client interactions.

Tools:

  • ResourceLoader offers a means to ensure JavaScript is easily viewable by client-side tools.
  • Open your browser's console. Many client side mediawiki scripts log error messages to the console using ResourceLoader, which provides a safety oriented way to log to the client console. Beyond the native JavaScript logging function, it provides a check to ensure that a console is available and that logging does not produce its own error. ResourceLoader/Architecture#Debug_mode also describes this feature.
  • Browser tools may provide native functionality to debug client side script.
  • Network tracers, like Wireshark can provide insight into the script that is being provided by a page.
  • You can add ?debug=true to your URL as in https://www.mediawiki.org/wiki/MediaWiki?debug=true to get more detailed information for debugging via your browser's console

Spyder is an open-source cross-platform integrated development environment (IDE) for scientific programming in the Python language. Spyder integrates with a number of prominent packages in the scientific Python stack, including NumPy, SciPy, Matplotlib, pandas, IPython, SymPy and Cython, as well as other open-source software.[3][4] It is released under the MIT license.[5]

Initially created and developed by Pierre Raybaut in 2009, since 2012 Spyder has been maintained and continuously improved by a team of scientific Python developers and the community.

Spyder is extensible with first-party and third-party plugins,[6] includes support for interactive tools for data inspection and embeds Python-specific code quality assurance and introspection instruments, such as Pyflakes, Pylint[7] and Rope. It is available cross-platform through Anaconda, on Windows, on macOS through MacPorts, and on major Linux distributions such as Arch Linux, Debian, Fedora, Gentoo Linux, openSUSE and Ubuntu.[8][9]

Spyder uses Qt for its GUI and is designed to use either of the PyQt or PySide Python bindings.[10] QtPy, a thin abstraction layer developed by the Spyder project and later adopted by multiple other packages, provides the flexibility to use either backend.[11]

Features[edit]

Features include:[12]

  • An editor with syntax highlighting, introspection, code completion
  • Support for multiple IPythonconsoles
