36 * This module implements Samba's debugging utility.
38 * The syntax of a debugging log file is represented as:
40 * <debugfile> :== { <debugmsg> }
42 * <debugmsg> :== <debughdr> '\n' <debugtext>
44 * <debughdr> :== '[' TIME ',' LEVEL ']' [ [FILENAME ':'] [FUNCTION '()'] ]
46 * <debugtext> :== { <debugline> }
48 * <debugline> :== TEXT '\n'
50 * TEXT is a string of characters excluding the newline character.
51 * LEVEL is the DEBUG level of the message (an integer in the range 0..10).
52 * TIME is a timestamp.
53 * FILENAME is the name of the file from which the debug message was generated.
54 * FUNCTION is the function from which the debug message was generated.
56 * Basically, what that all means is:
58 * - A debugging log file is made up of debug messages.
60 * - Each debug message is made up of a header and text. The header is
61 * separated from the text by a newline.
63 * - The header begins with the timestamp and debug level of the message
64 * enclosed in brackets. The filename and function from which the
65 * message was generated may follow. The filename is terminated by a
66 * colon, and the function name is terminated by parenthesis.
68 * - The message text is made up of zero or more lines, each terminated by
72 /* -------------------------------------------------------------------------- **
75 * dbf - Global debug file handle.
76 * debugf - Debug file name.
77 * DEBUGLEVEL - System-wide debug message limit. Messages with message-
78 * levels higher than DEBUGLEVEL will not be processed.

117 * debug_count - Number of debug messages that have been output.
118 * Used to check log size.
120 * syslog_level - Internal copy of the message debug level. Written by
121 * dbghdr() and read by Debug1().
123 * format_bufr - Used to format debug messages. The dbgtext() function
124 * prints debug messages to a string, and then passes the
125 * string to format_debug_text(), which uses format_bufr
126 * to build the formatted output.
128 * format_pos - Marks the first free byte of the format_bufr.
131 * log_overflow - When this variable is True, never attempt to check the
132 * size of the log. This is a hack, so that we can write
