37 * This module implements Samba's debugging utility.
39 * The syntax of a debugging log file is represented as:
41 * <debugfile> :== { <debugmsg> }
43 * <debugmsg> :== <debughdr> '\n' <debugtext>
45 * <debughdr> :== '[' TIME ',' LEVEL ']' [ [FILENAME ':'] [FUNCTION '()'] ]
47 * <debugtext> :== { <debugline> }
49 * <debugline> :== TEXT '\n'
51 * TEXT is a string of characters excluding the newline character.
52 * LEVEL is the DEBUG level of the message (an integer in the range 0..10).
53 * TIME is a timestamp.
54 * FILENAME is the name of the file from which the debug message was generated.
55 * FUNCTION is the function from which the debug message was generated.
57 * Basically, what that all means is:
59 * - A debugging log file is made up of debug messages.
61 * - Each debug message is made up of a header and text. The header is
62 * separated from the text by a newline.
64 * - The header begins with the timestamp and debug level of the message
65 * enclosed in brackets. The filename and function from which the
66 * message was generated may follow. The filename is terminated by a
67 * colon, and the function name is terminated by parenthesis.
69 * - The message text is made up of zero or more lines, each terminated by
73 /* -------------------------------------------------------------------------- **
76 * dbf - Global debug file handle.
77 * debugf - Debug file name.
78 * DEBUGLEVEL - System-wide debug message limit. Messages with message-
79 * levels higher than DEBUGLEVEL will not be processed.

117 * Used to check log size.
119 * syslog_level - Internal copy of the message debug level. Written by

125 * to build the formatted output.
127 * format_pos - Marks the first free byte of the format_bufr.
130 * log_overflow - When this variable is True, never attempt to check the

984 from which this function was called, or an empty string
