Trac - The Trac Configuration File - 配置文件

The Trac Configuration File

[Note To Editors] Please discuss documentation changes in the #Discussion section. Even better, send us documentation patches against the code (i.e. where the configuration entries are documented), either on Trac-dev or on new tickets.

Trac configuration is done by editing the trac.ini config file, located in /conf/trac.ini. Changes to the configuration are usually reflected immediately, though changes to the [components] or [logging] sections will require restarting the web server. You may also need to restart the web server after creating a global configuration file when none was previously present.

Global Configuration

In previous versions, the global configuration was by default located in $prefix/share/trac/conf/trac.ini or sometimes /etc/trac/trac.ini depending on the distribution. If you're upgrading, you may want to specify that file to inherit from.

Global options will be merged with the environment-specific options, where local options override global options. The options file is specified as follows:

[inherit]
file = /usr/share/trac/conf/trac.ini

Note that you can also specify a global option file when creating a new project, by adding the option --inherit=/path/to/global/options to trac-admin's initenv command. If you would not do this but nevertheless intend to use a global option file with your new environment, you would have to go through the newly generated conf/trac.ini file and delete the entries that would otherwise override those set in the global file.

Reference

This is a brief reference of available configuration options.

[attachment]

max_size	Maximum allowed file size for ticket and wiki attachments.
render_unsafe_content	Whether attachments should be rendered in the browser, or only made downloadable. Pretty much any file may be interpreted as HTML by the browser, which allows a malicious user to attach a file containing cross-site scripting attacks. For public sites where anonymous users can create attachments it is recommended to leave this option disabled (which is the default).

[bitten]

adjust_timestamps	Whether the timestamps of builds should be adjusted to be close to the timestamps of the corresponding changesets.
build_all	Whether to request builds of older revisions even if a younger revision has already been built.
slave_timeout	The time in seconds after which a build is cancelled if the slave does not report progress.
stabilize_wait	The time in seconds to wait for the repository to stabilize before queuing up a new build. This allows time for developers to check in a group of related changes back to back without spawning multiple builds.

[browser]

color_scale	Enable colorization of the age column. This uses the same color scale as the source code annotation: blue is older, red is newer. (since 0.11)
downloadable_paths	List of repository paths that can be downloaded. Leave the option empty if you want to disable all downloads, otherwise set it to a comma-separated list of authorized paths (those paths are glob patterns, i.e. "*" can be used as a wild card) (since 0.10)
hide_properties	Comma-separated list of version control properties to hide from the repository browser. (since 0.9)
intermediate_color	(r,g,b) color triple to use for the color corresponding to the intermediate color, if two linear interpolations are used for the color scale (see intermediate_point). If not set, the intermediate color between oldest_color and newest_color will be used. (since 0.11)
intermediate_point	If set to a value between 0 and 1 (exclusive), this will be the point chosen to set the intermediate_color for interpolating the color value. (since 0.11)
newest_color	(r,g,b) color triple to use for the color corresponding to the newest color, for the color scale used in blame or the browser age column if color_scale is enabled. (since 0.11)
oldest_color	(r,g,b) color triple to use for the color corresponding to the oldest color, for the color scale used in blame or the browser age column if color_scale is enabled. (since 0.11)
oneliner_properties	Comma-separated list of version control properties to render as oneliner wiki content in the repository browser. (since 0.11)
render_unsafe_content	Whether attachments should be rendered in the browser, or only made downloadable. Pretty much any file may be interpreted as HTML by the browser, which allows a malicious user to attach a file containing cross-site scripting attacks. For public sites where anonymous users can create attachments it is recommended to leave this option disabled (which is the default).
wiki_properties	Comma-separated list of version control properties to render as wiki content in the repository browser. (since 0.11)

[changeset]

max_diff_bytes	Maximum total size in bytes of the modified files (their old size plus their new size) for which the changeset view will attempt to show the diffs inlined (since 0.10).
max_diff_files	Maximum number of modified files for which the changeset view will attempt to show the diffs inlined (since 0.10).
wiki_format_messages	Whether wiki formatting should be applied to changeset messages. If this option is disabled, changeset messages will be rendered as pre-formatted text.

[header_logo]

alt	Alternative text for the header logo.
height	Height of the header logo image in pixels.
link	URL to link to from header logo.
src	URL of the image to use as header logo.
width	Width of the header logo image in pixels.

templates_dir	Path to the shared templates directory. Templates in that directory are loaded in addition to those in the environments templates directory, but the latter take precedence. (since 0.11)

[logging]

log_file	If log_type is file, this should be a path to the log-file.
log_format	Custom logging format. If nothing is set, the following will be used: Trac[$(module)s] $(levelname)s: $(message)s In addition to regular key names supported by the Python logger library library (see http://docs.python.org/lib/node422.html), one could use: - $(path)s the path for the current environment - $(basename)s the last path component of the current environment - $(project)s the project name Note the usage of $(...)s instead of %(...)s as the latter form would be interpreted by the ConfigParser? itself. Example: ($(thread)d) Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s (since 0.11)
log_level	Level of verbosity in log. Should be one of (CRITICAL, ERROR, WARN, INFO, DEBUG).

深入浅出Java Annotation(元注解和自定义注解） Josh_Persistence Java Annotation元注解自定义注解 一、基本概述     　　 Annontation是Java5开始引入的新特征。中文名称一般叫注解。它提供了一种安全的类似注释的机制，用来将任何的信息或元数据（metadata）与程序元素（类、方法、成员变量等）进行关联。   　　更通俗的意思是为程序的元素（类、方法、成员变量）加上更直观更明了的说明，这些说明信息是与程序的业务逻辑无关，并且是供指定的工具或 mysql优化特定类型的查询 annan211 java工作mysql 本节所介绍的查询优化的技巧都是和特定版本相关的，所以对于未来mysql的版本未必适用。 1 优化count查询 对于count这个函数的网上的大部分资料都是错误的或者是理解的都是一知半解的。在做优化之前我们先来看看 真正的count()函数的作用到底是什么。 count()是一个特殊的函数，有两种非常不同的作用，他可以统计某个列值的数量，也可以统计行数。 在统 MAC下安装多版本JDK和切换几种方式 棋子chessman jdk 环境： MAC AIR,OS X 10.10,64位   历史： 过去 Mac 上的 Java 都是由 Apple 自己提供，只支持到 Java 6，并且OS X 10.7 开始系统并不自带（而是可选安装）（原自带的是1.6）。 后来 Apple 加入 OpenJDK 继续支持 Java 6，而 Java 7 将由 Oracle 负责提供。   在终端中输入jav javaScript （1） Array_06 JavaScriptjava浏览器 JavaScript 1、运算符 　　运算符就是完成操作的一系列符号，它有七类： 　　赋值运算符（=,+=,-=,*=,/=,%=,<<=,>>=,|=,&=）、算术运算符(+,-,*,/,++,--,%)、比较运算符(>,<,<=,>=,==,===,!=,!==)、逻辑运算符(||,&&,!)、条件运算(?:)、位 国内顶级代码分享网站 袁潇含 javajdkoracle.netPHP

IT界在过去几年中出现了一个有趣的现象。很多新的技术出现并立即拥抱了“大数据”。稍微老一点的技术也会将大数据添进自己的特性，避免落大部队太远，我们看到了不同技术之间的边际的模糊化。假如你有诸如Elasticsearch或者Solr这样的搜索引擎，它们存储着JSON文档，MongoDB存着JSON文档，或者一堆JSON文档存放在一个Hadoop集群的HDFS中。你可以使用这三种配 mac os

    最暴力的方式是new一个集合对象，然后遍历数组，依次将数组中的元素放入到新的集合中，但是这样做显然过 nginx同一主机部署多个应用 geeksun nginx 近日有一需求，需要在一台主机上用nginx部署2个php应用，分别是wordpress和wiki，探索了半天，终于部署好了，下面把过程记录下来。 1.   在nginx下创建vhosts目录，用以放置vhost文件。 mkdir

在进行数据传输时JSON格式目前应用广泛，因此从Lua对象与JSON字符串之间相互转换是一个非常常见的功能；目前Lua也有几个JSON库，本人用过cjson、dkjson。其中cjson的语法严格（比如unicode \u0020\u7eaf），要求符合规范否则会解析失败（如\u002），而dkjson相对宽松，当然也可以通过修改cjson的源码来完成

在写DAO层时，觉得从Cursor里一个一个的取出字段值再装到VO(值对象)里太麻烦了，就写了一个工具类，用到了反射，可以把查询记录的值装到对应的VO里，也可以生成该VO的List。   使用时需要注意： 考虑到Android的性能问题，VO没有使用Setter和Getter，而是直接用public的属性。 表中的字段名需要和VO的属性名一样，要是不一样就得在查询的SQL中
