如何清理Drupal主机储存空间

yunke — Wed, 22 Nov 2023 03:12:56 +0000

如何清理Drupal主机储存空间 yunke 周三, 11/22/2023 - 11:12

双十一刚过，阿里云等等平台推出了比较优惠的云主机，但储存空间只有40GB，这也导致许多Drupal学员因为储存空间问题产生困扰，刚装时好好的，运行一段时间后怎么储存空间就不够用了？本文针对主要问题教你清理储存空间。

当主机储存空间爆满后，Drupal网站在设置为不显示错误详情时，会提示遇到不可知问题无法访问，连后台都进入不了，此时可以远程登录服务器，删除一些不要的文件，这样就可以短暂恢复访问了，因此平时可以放几百兆的无用文件在服务器上，以应对这个问题。

删除及禁用Drupal缓存：

然后马上登录网站后台，去删除缓存（管理-配置-开发-性能-清空所有缓存），缓存是Drupal储存空间的消耗大户，耗费空间的主要原因之一，存在目的是加速网站访问，以空间换时间，如果你实在不想增加储存空间，缓存又增长过快，那么可以禁用缓存，这里以最大的页面缓存（缓存表为：cache_page）为例来讲解如何做:

打开配置文件（默认为sites\default\settings.php）,在末尾加上这一行：

$settings['cache']['bins']['page']="cache.backend.memory";

这代表将page缓存储存到内存中去，这样就不会占用硬盘空间了（实际上更好的办法是储存到NULL缓存中去，但系统没有提供现成的服务，不过提供有NULL缓存类，可以去自定义一个NULL缓存服务）

禁用数据库二进制日志：

另一个储存空间消耗大户就是数据库的二进制日志文件，可以达到几十GB，在MYSQL 8.0中默认是开启的

首先将Mysql添加到系统环境变量中去，假设用的是Win服务器，可以右击“此电脑”，然后选：属性-高级系统设置-环境变量-找到Path然后点击编辑，将mysql的安装路径添加进去，最后保存

打开命令行终端登录数据库：

mysql -u root -p

接着输入密码进入

查询二进制日志是否处于打开状态：

SHOW VARIABLES LIKE 'log_bin';

如果是打开的，那么删除这些二进制日志（在开启二进制日志的情况下才有效），命令如下：

RESET MASTER;

长久关闭二进制日志，打开数据库配置文件（my.ini），添加：

skip-log-bin或disable-log-bin

然后重启，暂停二进制日志可以使用以下命令：

SET SQL_LOG_BIN=0;

以上是耗费空间的两个主要原因，通过如上处理，Drupal服务器的大部分储存空间就清理出来了

为什么有时候开发难以按预期完成？

yunke — Sat, 26 Aug 2023 03:21:26 +0000

为什么有时候开发难以按预期完成？ yunke 周六, 08/26/2023 - 11:21

水滴间网站现已升级到Drupal10，默认主题已随之切换为olivero主题，这里以升级过程中遇到的一个问题来说明：为什么有时候开发难以按预期完成，问题描述如下：

BigPipe模块导致olivero主题在导航菜单中，点击搜索图标不弹出搜索表单的问题

升级Drupal 10 后，发现点击导航栏中的搜索放大镜图标无法弹出搜索表单，浏览器控制台显示以下错误：

Uncaught TypeError: Cannot read properties of null (reading 'classList')

排查过程如下：
最直接的原因是web\core\themes\olivero\js\search.js文件的第10-12行代码：

  const searchWideWrapperSelector ='[data-drupal-selector="block-search-wide-wrapper"]';
  const searchWideWrapper = document.querySelector(searchWideWrapperSelector);

无法找到这个搜索表单包装元素，但在浏览器控制台中查看是有这个元素的

然后查看源代码，发现这个搜索表单元素被BigPipe模块做了处理，此时你需要知道BigPipe模块的作用：

它将不耗时的静态内容先发送给浏览器，以便浏览器尽快有所显示，避免用户等待着急，而将页面中耗时的动态内容先用占位符替换，等浏览器渲染完页面后，再从后端拉取那些动态内容来替换之前放置的相应占位符。

换句话说：BigPipe模块就是将内容分批发送，以便浏览器尽快显示，而传统方式是将内容一次性发送，这样做的目的是尽可能快的显示页面，提高用户体验。

之所以搜索js找不到表单包装元素而浏览器控制台中能看到，就是因为查找时机发生在动态内容替换占位符之前，此时尚未替换，当然就找不到，所以报错无法弹出搜索表单了。

那么BigPipe模块为什么要把搜索表单识别成动态内容加以处理呢？默认情况下是不会这样的，进一步排查，是因为“yunke_captcha”模块为所有的表单元素添加了缓存元数据（这样做的目的是验证码配置变动后及时让表单响应更新，逻辑上是没有问题的），正是因为向表单元素添加了缓存元数据这个动作，导致了BigPipe模块将搜索表单元素识别为动态内容，从而进行了处理，进而导致了搜索表单无法弹出。

一个JS错误，想不到会牵扯到两个模块和缓存系统。

这是一个非常典型的故障排除案例，一个小故障导致一连窜的分析检查，所以，为什么说开发有时候难以按预期完成进度？就是因为不知道有什么坑在前方等着，也不知道会为此耗去多少时间去查阅那些本不用查阅的资料

目前“yunke_captcha”模块已对该问题做了规避，为此发布了2.4版本

但该问题并不是“yunke_captcha”模块的bug，而是olivero主题和BigPipe模块需要改进，尤其是BigPipe模块需要添加排除处理的方法，云客针对该问题已向Drupal官方提交修复建议

Drupal 9 升级到 Drupal 10 干货详解

yunke — Wed, 23 Aug 2023 11:15:04 +0000

Drupal 9 升级到 Drupal 10 干货详解 yunke 周三, 08/23/2023 - 19:15

首先，升级到Drupal 10前，需要先升级到Drupal 9.5 ，升级到Drupal 9.5比较容易，属于大版本内升级，具体过程这里略过

升级到Drupal 9.5后，安装CKEditor 5模块，并在“管理-配置-内容写作-文本格式和编辑器”中，在用到富文本编辑器的条目中，手动更新CKEditor 4 到 CKEditor 5

然后，如果安装了以下这些被弃用的模块，那么卸载它们：

CKEditor (CKEditor 4)
Color
RDF
Quick Edit
HAL

安装启用新的默认主题并重新设置主题，卸载弃用的主题

接着升级所有模块到兼容D10，然后运行下方命令升级核心到Drupal 10：

composer require drupal/core-recommended:10.0.0 drupal/core-composer-scaffold:10.0.0 drupal/core-project-message:10.0.0 --update-with-all-dependencies

现在代码库已经升级到D10了，接着升级数据库：
先修改配置文件（settings.php）中的：$settings['update_free_access'] 项的值为TRUE，这样将允许你在不登录维护账号的情况下也能执行升级脚本，后续完成升级后记得改回： false
运行升级脚本：update.php

顺利的话，现在你已经升级到Drupal 10了，可以继续升级到最新版本的Drupal 10

现在做一些升级完成的善后工作：
1、使用Apache的用户注意：.htaccess 文件有改变，需要在新的文件上手动添加自定义的部分内容
2、默认的robots.txt文件已更新为不允许索引oEmbed媒体链接，替换该文件，有自定义部分则手动合并
3、站点services.yml文件有更新，需要手动合并
4、修改前述$settings['update_free_access'] 项的值为false
5、进入系统后台，查看状态报告页面以及日志页面，看是否有其他问题，一并修复

Drupal 10 运行环境要求：
php版本需要：PHP 8.1或者更高
由于 8.1.0 到 8.1.5有一个OPcache方面的bug，所以推荐8.1.6以上版本

数据库：
MySQL 或 Percona 5.7.8.
MariaDB 10.3.7

浏览器支持：
Internet Explorer 11不再被支持

Composer要求：
Drupal 10推荐Composer版本在2.3.6或更高

补充说明：
1、在不卸载模块的情况下，如果你需要移动模块位置，可以直接移动，然后运行一次升级脚本即可
注：如果是卸载方式移动会导致模块配置丢失，在有复杂依赖时，情况更糟，此知识点可以帮你避免这一点

2、官方升级指导页：

在不卸载Drupal模块的情况下，如何移动更改模块所在的目录？

yunke — Tue, 22 Aug 2023 08:21:50 +0000

在不卸载Drupal模块的情况下，如何移动更改模块所在的目录？ yunke 周二, 08/22/2023 - 16:21

在有些情况下，我们需要移动Drupal模块所在的目录，比如开始使用Composer管理系统代码，或者将某个单站的模块用于多站时

如果你直接移动模块文件夹，那么系统会提示错误，日志里面会记录XX文件不存在，导致进不了后台

如果你卸载模块重新安装，那么模块的配置或数据就会丢失，在有很多模块依赖本模块时，更加复杂，需要修改太多内容

那怎么办呢？

其实很简单，你只需要移动模块后，运行一次“/update.php”升级程序即可

使用数据库工具Navicat备份还原Drupal数据库的注意事项

使用数据库工具Navicat备份还原Drupal数据库的注意事项 yunke 周五, 08/11/2023 - 15:40

在用Navicat数据库工具还原之前备份的Drupal数据库后，访问日志页面（/admin/reports/dblog），出现如下错误：

网站遇到了不可预知的错误。请稍后再试。

Error: Call to a member function getCacheMaxAge() on null in Drupal\views\Plugin\views\query\Sql->getCacheMaxAge() (line 1710 of core\modules\views\src\Plugin\views\query\Sql.php).

一度以为是模块问题，经排查，发现是数据库恢复时，用户数据表（users）中的匿名用户ID恢复错误！

匿名用户的用户ID（即uid）在Drupal中应该为0，但由于uid字段是自增的，且是主键，在用Navicat数据库工具恢复时，匿名用户的uid变成了自增的最大值，导致日志查询时，如果日志是匿名用户产生的，那么会由于找不到匿名用户账户，导致用户实体变量成为NULL，从而导致上面的错误

该种错误很罕见，排查时很难注意到是这个点，所有数据库工具在恢复时都应小心

Drupal安全相关设置处理

yunke — Fri, 28 Jul 2023 00:55:33 +0000

Drupal安全相关设置处理 yunke 周五, 07/28/2023 - 08:55

1、去除Drupal特征

可选去除首部产生器标签：
<meta name="Generator" content="Drupal 8 (https://www.drupal.org)" />
是在core/modules/system/system.module：system_page_attachments函数中设置，因此对应去除

可选去除http响应头：
服务名：response_generator_subscriber
执行方法：onRespond
优先级：0-2
只作用于主请求，在响应头中设置系统标志标签，值为：
X-Generator：'Drupal $version (https://www.drupal.org)'
通过该响应头可以看出网站使用了drupal系统，是一种宣传手段，没有什么实际用途，该服务定义在此文件中：core/core.services.yml，如果不需要可以进行服务覆写，也可以在事件派发器中移除该订阅器

可选去除特殊文件：
http://www.dp9.com/core/CHANGELOG.txt

2、上传文件名处理：

配置项：

\Drupal::config('system.file')->get('allow_insecure_uploads')

默认为false,应该保持默认值，如果为true，则上传的文件名不会被处理，有可能出现安全问题，有些服务器（比如Apache）在处理文件链接时，遇到不能识别的扩展名，会回退使用前面的扩展名，比如请求文件yunke.php.pps时，不能识别pps，那么将扩展名视为php，因此文件会被当做php文件执行，这导致了安全漏洞，因此文件上传后需要对文件名进行特殊检查处理，drupal使用以下函数来干这件事：

  file_munge_filename($filename, $extensions, $alerts = TRUE)

以上配置项影响该函数行为

Drupal是CMS还是CMF？

yunke — Tue, 18 Apr 2023 07:39:09 +0000

Drupal是CMS还是CMF？ yunke 周二, 04/18/2023 - 15:39

有的人把Drupal看做是一个CMS（内容管理系统），而有的则把它看做是CMF（内容管理框架），不管是CMS还是CMF，其实都对，只是个名字而已，不必太在意，从Drupal整体软件架构这个角度看，是分层设计的，上层系统建立在下层系统之上，依赖着下层系统：
类自动加载等基础设施算一层：这层都是web项目通用的
HTTP核心和容器可以算一层：单看这一层可以将Drupal视为开发框架
实体概念的实现算一层：在这一层上可以将Drupal视为内容管理框架，也就是CMF
再往上的表单系统、主题、权限控制等算一层：这一层非常接近应用，内容众多，站在这一层上可以将Drupal视为CMS

总结一下，Drupal系统架构可以分为如下四层：
基础层（基础的WEB组件，比如请求、响应对象、类加载器等，这层是web项目通用的，提供基础工具）
框架层（主要内容是HTTP核心和容器，你可以将Drupal当框架用）
数据层（数据库抽象层，实体）
应用层（权限控制、块系统、显示模式、视图等等）

角度不一样强调的东西不一样，说是CMS可能更多的是看到Drupal提供了直接使用的功能，说是CMF更多是看到了这种架构带来的灵活强大，完全取决于你想强调什么，Drupal确实非常强大灵活，设计优雅。

phpstudy自定义PHP版本的方法，为安装Drupal 10

yunke — Thu, 06 Apr 2023 03:27:57 +0000

phpstudy自定义PHP版本的方法，为安装Drupal 10 yunke 周四, 04/06/2023 - 11:27

Drupal 10 第一个正式版本已于2022年12月15日正式发布，其最低PHP版本要求为PHP 8.1，推荐为8.1.6以上，这困扰了一些在windows下使用集成安装环境的朋友，比如：phpstudy的php安装列表里面最高只支持到PHP 8.0.2，PHPCUSTOM直接没有PHP 8 的支持，这就需要我们自定义安装了，本文以安装Drupal 10为例，教你在phpstudy中自定义安装PHP的任意版本。

首先到PHP官网下载我们需要的PHP版本：
打开PHP官网，点击页面顶部的“Downloads”按钮，打开下载页面，找到所需的版本，然后点击“Windows downloads ”打开下载页面
这里我们以下载8.2.4为例，将打开
https://windows.php.net/download#php-8.2
然后依据自己操作系统的位数以及是否线程安全进行选择，32位操作系统就选择X86
这里我们选择64位非线程安全的版本，即“VS16 x64 Non Thread Safe”
然后点击其中的“Zip”子链接，即开始下载

然后找到phpstudy的PHP目录|：“\phpstudy_pro\Extensions\php\”
在其为我们刚刚下载的PHP版本创建一个目录，比如“php8.2.4nts”
然后将刚下载的PHP解压到该目录，此时“php.exe”的完整路径应该是：
phpstudy_pro\Extensions\php\php8.2.4nts\php.exe
双击它如果不能成功运行，那么你还需要安装微软的VC运行库，运行库下载地址：
https://visualstudio.microsoft.com/zh-hans/downloads/
找到“其他工具、框架和可再发行组件”然后下载里面的：
Microsoft Visual C++ Redistributable for Visual Studio 2022

经过以上操作，在phpstudy中已经可以为网站配置安装的PHP版本了
注意：此时在phpstudy自身的php安装列表中，依然看不到我们新安装的PHP版本，但没关系，他不影响使用，只需在网站配置页里面选择新安装的PHP版本即可

如果在配置中，选择php 8以上版本时，网站出现了500错误状态码，那么大概率是VC库没有安装好，按前述方法下载安装即可

还是希望这些集成环境能够快一点更新，免去使用者自己去安装的麻烦

现在我们来安装Drupal 10 ，为其配置好网站后，启动安装过程会提示有很多需要的PHP扩展没有被启用，那么我们来启用相关扩展

打开配置文件“phpstudy_pro\Extensions\php\php8.2.4nts\php.ini”，我们会发现里面是空的，其实php官方已经为我们提前准备好了两个预配置文件（在相同目录下）：
php.ini-development：开发环境下使用
php.ini-production：生成环境（正式上线服务的环境）

根据需要复制其中一个配置的内容到上述php.ini文件，再根据自己的配置需要进行细节修改，保存即可
这里提供一个完整的配置内容供新人朋友体验Drupal 10，配置如下：

[PHP]

;;;;;;;;;;;;;;;;;;;
; About php.ini   ;
;;;;;;;;;;;;;;;;;;;
; PHP's initialization file, generally called php.ini, is responsible for
; configuring many of the aspects of PHP's behavior.

; PHP attempts to find and load this configuration from a number of locations.
; The following is a summary of its search order:
; 1. SAPI module specific location.
; 2. The PHPRC environment variable.
; 3. A number of predefined registry keys on Windows
; 4. Current working directory (except CLI)
; 5. The web server's directory (for SAPI modules), or directory of PHP
; (otherwise in Windows)
; 6. The directory from the --with-config-file-path compile time option, or the
; Windows directory (usually C:\windows)
; See the PHP docs for more specific information.
; https://php.net/configuration.file

; The syntax of the file is extremely simple.  Whitespace and lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.

; Directives following the section heading [PATH=/www/mysite] only
; apply to PHP files in the /www/mysite directory.  Directives
; following the section heading [HOST=www.example.com] only apply to
; PHP files served from www.example.com.  Directives set in these
; special sections cannot be overridden by user-defined INI files or
; at runtime. Currently, [PATH=] and [HOST=] sections only work under
; CGI/FastCGI.
; https://php.net/ini.sections

; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
; Directives are variables used to configure PHP or PHP extensions.
; There is no name validation.  If PHP can't find an expected
; directive because it is not set or is mistyped, a default value will be used.

; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
; previously set variable or directive (e.g. ${foo})

; Expressions in the INI file are limited to bitwise operators and parentheses:
; |  bitwise OR
; ^  bitwise XOR
; &  bitwise AND
; ~  bitwise NOT
; !  boolean NOT

; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.

; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:

; foo =         ; sets foo to an empty string
; foo = None    ; sets foo to an empty string
; foo = "None"  ; sets foo to the string 'None'

; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; PHP comes packaged with two INI files. One that is recommended to be used
; in production environments and one that is recommended to be used in
; development environments.

; php.ini-production contains settings which hold security, performance and
; best practices at its core. But please be aware, these settings may break
; compatibility with older or less security conscience applications. We
; recommending using the production ini in production and testing environments.

; php.ini-development is very similar to its production variant, except it is
; much more verbose when it comes to errors. We recommend using the
; development version only in development environments, as errors shown to
; application users can inadvertently leak otherwise secure information.

; This is the php.ini-development INI file.

;;;;;;;;;;;;;;;;;;;
; Quick Reference ;
;;;;;;;;;;;;;;;;;;;

; The following are all the settings which are different in either the production
; or development versions of the INIs with respect to PHP's default behavior.
; Please see the actual settings later in the document for more details as to why
; we recommend these changes in PHP's behavior.

; Output buffering is a mechanism for controlling how much output data

; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance

; This directive informs PHP of which errors, warnings and notices you would like
; it to take action for. The recommended way of setting values for this
; directive is through the use of the error level constants and bitwise
; operators. The error level constants are below here for convenience as well as
; some common settings and their meanings.
; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
; those related to E_NOTICE and E_STRICT, which together cover best practices and
; recommended coding standards in PHP. For performance reasons, this is the
; recommend error reporting setting. Your production server shouldn't be wasting
; resources complaining about best practices and coding standards. That's what
; development servers and development settings are for.
; Note: The php.ini-development file has this setting as E_ALL. This
; means it pretty much reports everything which is exactly what you want during
; development and early testing.
;
; Error Level Constants:
; E_ALL             - All errors and warnings
; E_ERROR           - fatal run-time errors
; E_RECOVERABLE_ERROR  - almost fatal run-time errors
; E_WARNING         - run-time warnings (non-fatal errors)
; E_PARSE           - compile-time parse errors
; E_NOTICE          - run-time notices (these are warnings which often result
;                     from a bug in your code, but it's possible that it was
;                     intentional (e.g., using an uninitialized variable and
;                     relying on the fact it is automatically initialized to an
;                     empty string)
; E_STRICT          - run-time notices, enable to have PHP suggest changes
;                     to your code which will ensure the best interoperability
;                     and forward compatibility of your code
; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's
;                     initial startup
; E_COMPILE_ERROR   - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR      - user-generated error message
; E_USER_WARNING    - user-generated warning message
; E_USER_NOTICE     - user-generated notice message
; E_DEPRECATED      - warn about code that will not work in future versions
;                     of PHP
; E_USER_DEPRECATED - user-generated deprecation warnings
;
; Common Values:
;   E_ALL (Show all errors, warnings and notices including coding standards.)
;   E_ALL & ~E_NOTICE  (Show all errors, except for notices)
;   E_ALL & ~E_NOTICE & ~E_STRICT  (Show all errors, except for notices and coding standards warnings.)

; This directive controls whether or not and where PHP will output errors,

; For production environments, we recommend logging errors rather than

;
;     session.save_path = "N;/path"
;
; where N is an integer.  Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories.  This is useful if
; your OS has problems with many files in one directory, and is
; a more efficient layout for servers that handle many sessions.
;
; NOTE 1: PHP will not create this directory structure automatically.
;         You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
;         use subdirectories for session storage

知道吗？网页程序也可以跨程序（窗口）录屏

知道吗？网页程序也可以跨程序（窗口）录屏 yunke 周三, 11/02/2022 - 14:09

在网页里面运行的JS程序，也是可以做到跨程序录屏的，比如录制QQ聊天界面、PPT展示等等，作为资深开发者，你可能会立即思考JS能力和权限的问题，它怎么可能逃出浏览器，访问到其他程序了呢？这仰仗WebRTC技术，在用户授权下可安全使用。

演示示例如下：
屏幕录屏：
加载的JS文件如下：


const videoElem = document.getElementById("video");
const logElem = document.getElementById("log");
const startElem = document.getElementById("start");
const stopElem = document.getElementById("stop");

// Options for getDisplayMedia()

var displayMediaOptions = {
    video: {
        cursor: "always"
    },
    audio: false
};

// Set event listeners for the start and stop buttons
startElem.addEventListener("click", function (evt) {
    startCapture();
}, false);

stopElem.addEventListener("click", function (evt) {
    stopCapture();
}, false);

console.log = msg => logElem.innerHTML += `${msg}<br>`;
console.error = msg => logElem.innerHTML += `<span class="error">${msg}</span><br>`;
console.warn = msg => logElem.innerHTML += `<span class="warn">${msg}<span><br>`;
console.info = msg => logElem.innerHTML += `<span class="info">${msg}</span><br>`;

async function startCapture() {
    logElem.innerHTML = "";

    try {
        videoElem.srcObject = await navigator.mediaDevices.getDisplayMedia(displayMediaOptions);
        dumpOptionsInfo();
    } catch (err) {
        console.error("Error: " + err);
    }
}

function stopCapture(evt) {
    let tracks = videoElem.srcObject.getTracks();

    tracks.forEach(track => track.stop());
    videoElem.srcObject = null;
}

function dumpOptionsInfo() {
    const videoTrack = videoElem.srcObject.getVideoTracks()[0];

    console.info("Track settings:");
    console.info(JSON.stringify(videoTrack.getSettings(), null, 2));
    console.info("Track constraints:");
    console.info(JSON.stringify(videoTrack.getConstraints(), null, 2));
}
