* Read configuration from a file. <b>The existing configuration is

* resetConfiguration} method before calling
* <code>doConfigure</code>.
*
* The configuration file consists of statements in the format
* <code>key=value</code>. The syntax of different configuration
* elements are discussed below.
*
* <h3>Appender configuration</h3>
*
* Appender configuration syntax is:
* <pre>
* # For appender named <i>appenderName</i>, set its class.
* # Note: The appender name can contain dots.
* log4cplus.appender.appenderName=fully.qualified.name.of.appender.class
*
* # Set appender specific options.
* log4cplus.appender.appenderName.option1=value1
* ...
* log4cplus.appender.appenderName.optionN=valueN
* </pre>
*
* For each named appender you can configure its {@link Layout}. The
* syntax for configuring an appender's layout is:
* <pre>
* log4cplus.appender.appenderName.layout=fully.qualified.name.of.layout.class
* log4cplus.appender.appenderName.layout.option1=value1
* ....
* log4cplus.appender.appenderName.layout.optionN=valueN
* </pre>
*
* <h3>Configuring loggers</h3>
*
* The syntax for configuring the root logger is:
* <pre>
* log4cplus.rootLogger=[LogLevel], appenderName, appenderName, ...
* </pre>
*
* This syntax means that an optional <em>LogLevel value</em> can
* be supplied followed by appender names separated by commas.
*
* The LogLevel value can consist of the string values FATAL,
* ERROR, WARN, INFO, DEBUG or a <em>custom LogLevel</em> value.
*
* If a LogLevel value is specified, then the root LogLevel is set
* to the corresponding LogLevel. If no LogLevel value is specified,
* then the root LogLevel remains untouched.
*
* The root logger can be assigned multiple appenders.
*
* Each <i>appenderName</i> (separated by commas) will be added to
* the root logger. The named appender is defined using the
* appender syntax defined above.
*
* For non-root loggers the syntax is almost the same:
* <pre>
* log4cplus.logger.logger_name=[LogLevel|INHERITED], appenderName, appenderName, ...
* </pre>
*
* The meaning of the optional LogLevel value is discussed above
* in relation to the root logger. In addition however, the value
* INHERITED can be specified meaning that the named logger should
* inherit its LogLevel from the logger hierarchy.
*
* By default loggers inherit their LogLevel from the
* hierarchy. However, if you set the LogLevel of a logger and
* later decide that that logger should inherit its LogLevel, then
* you should specify INHERITED as the value for the LogLevel value.
*
* Similar to the root logger syntax, each <i>appenderName</i>
* (separated by commas) will be attached to the named logger.
*
* See the <a href="../../../../manual.html#additivity">appender
* additivity rule</a> in the user manual for the meaning of the
* <code>additivity</code> flag.
*
* The user can override any of the {@link
* Hierarchy#disable} family of methods by setting the a key
* "log4cplus.disableOverride" to <code>true</code> or any value other
* than false. As in <pre>log4cplus.disableOverride=true </pre>
*
* <h3>Example</h3>
*
* An example configuration is given below.
*
* <pre>
*
* # Set options for appender named "A1".
* # Appender "A1" will be a SyslogAppender
* log4cplus.appender.A1=log4cplus::SyslogAppender
*
* # The syslog daemon resides on www.abc.net
* log4cplus.appender.A1.SyslogHost=www.abc.net
*
* # A1's layout is a PatternLayout, using the conversion pattern
* # <b>%r %-5p %c{2} %M.%L %x - %m\n</b>. Thus, the log output will
* # include # the relative time since the start of the application in
* # milliseconds, followed by the LogLevel of the log request,
* # followed by the two rightmost components of the logger name,
* # followed by the callers method name, followed by the line number,
* # the nested disgnostic context and finally the message itself.
* # Refer to the documentation of {@link PatternLayout} for further information
* # on the syntax of the ConversionPattern key.
* log4cplus.appender.A1.layout=log4cplus::PatternLayout
* log4cplus.appender.A1.layout.ConversionPattern=%-4r %-5p %c{2} %M.%L %x - %m\n
*
* # Set options for appender named "A2"
* # A2 should be a RollingFileAppender, with maximum file size of 10 MB
* # using at most one backup file. A2's layout is TTCC, using the
* # ISO8061 date format with context printing enabled.
* log4cplus.appender.A2=log4cplus::RollingFileAppender
* log4cplus.appender.A2.MaxFileSize=10MB
* log4cplus.appender.A2.MaxBackupIndex=1
* log4cplus.appender.A2.layout=log4cplus::TTCCLayout
* log4cplus.appender.A2.layout.ContextPrinting=enabled
* log4cplus.appender.A2.layout.DateFormat=ISO8601
*
* # Root logger set to DEBUG using the A2 appender defined above.
* log4cplus.rootLogger=DEBUG, A2
*
* # Logger definitions:
* # The SECURITY logger inherits is LogLevel from root. However, it's output
* # will go to A1 appender defined above. It's additivity is non-cumulative.
* log4cplus.logger.SECURITY=INHERIT, A1
* log4cplus.additivity.SECURITY=false
*
* # Only warnings or above will be logged for the logger "SECURITY.access".
* # Output will go to A1.
* log4cplus.logger.SECURITY.access=WARN
*
*
* # The logger "class.of.the.day" inherits its LogLevel from the
* # logger hierarchy. Output will go to the appender's of the root
* # logger, A2 in this case.
* log4cplus.logger.class.of.the.day=INHERIT

/**
* A flexible layout configurable with pattern string.
*
* The goal of this class is to format a InternalLoggingEvent and return
* the results as a string. The results depend on the <em>conversion
* pattern</em>.
*
* The conversion pattern is closely related to the conversion
* pattern of the printf function in C. A conversion pattern is
* composed of literal text and format control expressions called
* <em>conversion specifiers</em>.
*
* <i>You are free to insert any literal text within the conversion
* pattern.</i>
*
* Each conversion specifier starts with a percent sign (%%) and is
* followed by optional <em>format modifiers</em> and a <em>conversion
* character</em>. The conversion character specifies the type of
* data, e.g. Logger, LogLevel, date, thread name. The format
* modifiers control such things as field width, padding, left and
* right justification. The following is a simple example.
*
* Let the conversion pattern be <b>"%-5p [%t]: %m%n"</b> and assume
* that the log4cplus environment was set to use a PatternLayout. Then the
* statements
* <code><pre>
* Logger root = Logger.getRoot();
* LOG4CPLUS_DEBUG(root, "Message 1");
* LOG4CPLUS_WARN(root, "Message 2");
* </pre></code>
* would yield the output
* <tt><pre>
* DEBUG [main]: Message 1
* WARN [main]: Message 2
* </pre></tt>
*
* Note that there is no explicit separator between text and
* conversion specifiers. The pattern parser knows when it has reached
* the end of a conversion specifier when it reads a conversion
* character. In the example above the conversion specifier
* <b>"%-5p"</b> means the LogLevel of the logging event should be left
* justified to a width of five characters.
*
* The recognized conversion characters are
*
*
* <table border="1" CELLPADDING="8">
* <tr>
* <td>Conversion Character</td>
* <td>Effect</td>
* </tr>
*
* <tr>
* <td align=center><b>b</b></td>
*
* <td>Used to output file name component of path name.
* E.g. <tt>main.cxx</tt> from path <tt>../../main.cxx</tt>.</td>
* </tr>
*
* <tr>
* <td align=center><b>c</b></td>
*
* <td>Used to output the logger of the logging event. The
* logger conversion specifier can be optionally followed by
* <em>precision specifier</em>, that is a decimal constant in
* brackets.
*
* If a precision specifier is given, then only the corresponding
* number of right most components of the logger name will be
* printed. By default the logger name is printed in full.
*
* For example, for the logger name "a.b.c" the pattern
* <b>%c{2}</b> will output "b.c".
*
* </td>
* </tr>
*
* <tr>
* <td align=center><b>d</b></td>
*
* <td>Used to output the date of the logging event in <b>UTC</b>.
*
* The date conversion specifier may be followed by a <em>date format
* specifier</em> enclosed between braces. For example, <b>%%d{%%H:%%M:%%s}</b>
* or <b>%%d{%%d&nbsp;%%b&nbsp;%%Y&nbsp;%%H:%%M:%%s}</b>. If no date format
* specifier is given then <b>%%d{%%d&nbsp;%%m&nbsp;%%Y&nbsp;%%H:%%M:%%s}</b>
* is assumed.
*
* The Following format options are possible:
* <ul>
* <li>%%a -- Abbreviated weekday name</li>
* <li>%%A -- Full weekday name</li>
* <li>%%b -- Abbreviated month name</li>
* <li>%%B -- Full month name</li>
* <li>%%c -- Standard date and time string</li>

*
* By default the relevant information is output as is. However,
* with the aid of format modifiers it is possible to change the
* minimum field width, the maximum field width and justification.
*
* The optional format modifier is placed between the percent sign
* and the conversion character.
*
* The first optional format modifier is the <em>left justification
* flag</em> which is just the minus (-) character. Then comes the
* optional <em>minimum field width</em> modifier. This is a decimal
* constant that represents the minimum number of characters to
* output. If the data item requires fewer characters, it is padded on
* either the left or the right until the minimum width is
* reached. The default is to pad on the left (right justify) but you
* can specify right padding with the left justification flag. The
* padding character is space. If the data item is larger than the
* minimum field width, the field is expanded to accommodate the
* data. The value is never truncated.
*
* This behavior can be changed using the <em>maximum field
* width</em> modifier which is designated by a period followed by a
* decimal constant. If the data item is longer than the maximum
* field, then the extra characters are removed from the
* <em>beginning</em> of the data item and not from the end. For
* example, it the maximum field width is eight and the data item is
* ten characters long, then the first two characters of the data item
* are dropped. This behavior deviates from the printf function in C
* where truncation is done from the end.
*
* Below are various format modifier examples for the logger
* conversion specifier.
*
*
* <TABLE BORDER=1 CELLPADDING=8>
* <tr>
* <td>Format modifier</td>
* <td>left justify</td>
* <td>minimum width</td>

*
* <dt><b>"%r [%t] %-5p %c %x - %m%n"</b>
* <dd>This is essentially the TTCC layout.
*
* <dt><b>"%-6r [%15.15t] %-5p %30.30c %x - %m%n"</b>
*
* <dd>Similar to the TTCC layout except that the relative time is
* right padded if less than 6 digits, thread name is right padded if
* less than 15 characters and truncated if longer and the logger
* name is left padded if shorter than 30 characters and truncated if
* longer.

/**
* The NDC class implements <i>nested diagnostic contexts</i> as
* defined by Neil Harrison in the article "Patterns for Logging
* Diagnostic Messages" part of the book "<i>Pattern Languages of
* Program Design 3</i>" edited by Martin et al.
*
* A Nested Diagnostic Context, or NDC in short, is an instrument
* to distinguish interleaved log output from different sources. Log
* output is typically interleaved when a server handles multiple
* clients near-simultaneously.
*
* Interleaved log output can still be meaningful if each log entry
* from different contexts had a distinctive stamp. This is where NDCs
* come into play.
*
* <em><b>Note that NDCs are managed on a per thread
* basis</b></em>. NDC operations such as {@link #push}, {@link
* #pop}, {@link #clear}, {@link #getDepth} and {@link #setMaxDepth}
* affect the NDC of the <em>current</em> thread only. NDCs of other
* threads remain unaffected.
*
* For example, a server can build a per client request NDC
* consisting the clients host name and other information contained in
* the the request. <em>Cookies</em> are another source of distinctive
* information. To build an NDC one uses the {@link #push}
* operation. Simply put,
*
* <ul>
* <li>Contexts can be nested.
*
* <li>When entering a context, call <code>getNDC().push()</code>. As a
* side effect, if there is no nested diagnostic context for the
* current thread, this method will create it.
*
* <li>When leaving a context, call <code>getNDC().pop()</code>.
*
* <li><b>When exiting a thread make sure to call {@link #remove
* NDC.remove()}</b>.
* </ul>
*
* There is no penalty for forgetting to match each
* <code>push</code> operation with a corresponding <code>pop</code>,
* except the obvious mismatch between the real application context
* and the context set in the NDC. Use of the {@link NDCContextCreator}
* class can automate this process and make your code exception-safe.
*
* If configured to do so, {@link log4cplus::PatternLayout} and {@link
* log4cplus::TTCCLayout} instances automatically retrieve the nested diagnostic
* context for the current thread without any user intervention.
* Hence, even if a server is serving multiple clients
* simultaneously, the logs emanating from the same code (belonging to
* the same logger) can still be distinguished because each client
* request will have a different NDC tag.
*
* Heavy duty systems should call the {@link #remove} method when
* leaving the run method of a thread. This ensures that the memory
* used by the thread can be freed.
*
* A thread may inherit the nested diagnostic context of another
* (possibly parent) thread using the {@link #inherit inherit}
* method. A thread may obtain a copy of its NDC with the {@link
* #cloneStack cloneStack} method and pass the reference to any other
* thread, in particular to a child.

/**
* Sends {@link spi::InternalLoggingEvent} objects to a remote a log server.
*
* The SocketAppender has the following properties:
*
* <ul>
*
* <li>Remote logging is non-intrusive as far as the log event
* is concerned. In other words, the event will be logged with
* the same time stamp, NDC, location info as if it were logged
* locally by the client.
*
* <li>SocketAppenders do not use a layout.
*
* <li>Remote logging uses the TCP protocol. Consequently, if
* the server is reachable, then log events will eventually arrive
* at the server.
*
* <li>If the remote server is down, the logging requests are
* simply dropped. However, if and when the server comes back up,
* then event transmission is resumed transparently. This
* transparent reconneciton is performed by a <em>connector</em>
* thread which periodically attempts to connect to the server.
*
* <li>Logging events are automatically <em>buffered</em> by the
* native TCP implementation. This means that if the link to server
* is slow but still faster than the rate of (log) event production
* by the client, the client will not be affected by the slow
* network connection. However, if the network connection is slower
* then the rate of event production, then the client can only
* progress at the network rate. In particular, if the network link
* to the the server is down, the client will be blocked.
*
* <li>On the other hand, if the network link is up, but the server
* is down, the client will not be blocked when making log requests
* but the log events will be lost due to server unavailability.
* </ul>
