* bgp_main.c: (main) The 2nd argument to openzlog has been removed.
* isis_main.c: (main) The 2nd argument to openzlog has been removed.
* ospf6_main.c: (main) The 2nd argument to openzlog has been removed.
Note that stdout logging will no longer be enabled by default when
not running as a daemon.
* ospf_main.c: (main) The 2nd argument to openzlog has been removed.
* rip_main.c: (main) The 2nd argument to openzlog has been removed.
* ripng_main.c: (main) The 2nd argument to openzlog has been removed.
* main.c: (main) The 2nd argument to openzlog has been removed.
So stdout logging will no longer be enabled by default.
* irdp_main.c: (irdp_finish) Reduce severity of shutdown message
from LOG_WARNING to LOG_INFO.
* vtysh.c: Make several functions static instead of global.
Added several commands to support destination-specific logging levels.
(vtysh_completion) This function is unused, so comment it out.
* basic.texi: Document new logging features. Separate basic config
commands from basic VTY commands.
* log.h: Replace struct zlog flags and maskpri fields with maxlvl
array to support individual logging levels for each destination.
Remove the 2nd argument to openzlog since the default logging config
should be standardized inside the library. Replaced the
zlog_set_flag and zlog_reset_flag functions with zlog_set_level.
And zlog_set_file now requires an additional log_level argument.
Declare zlog_proto_names for use inside command.c in the
"show logging" command. Added defines useful for command
construction.
* log.c: (vzlog) Decide where to send the message based on the
individual logging levels configured for each destination.
Remove support for ZLOG_STDERR since it was never actually used.
Support record-priority for terminal monitors.
(zlog_signal,zlog_backtrace_sigsafe) Support destination-specific
logging levels. Remove stderr support (was never used). Added
support for terminal monitor logging.
(_zlog_assert_failed) Increase message severity to LOG_EMERG.
(openzlog) Remove 2nd argument since default config should be
standardized in library. By default, terminal monitoring
is set to debug, and all other logging is disabled.
(zlog_set_flag,zlog_reset_flag) Removed.
(zlog_set_level) New function to replace zlog_set_flag and
zlog_reset_flag. Supports destination-specific logging levels.
(zlog_set_file,zlog_reset_file) Support file-specific logging level.
(zlog_rotate) Log an error message if fopen fails, and support
new file-specific logging level.
* command.h: Change DEFUN_CMD_FUNC_DECL and DEFUN_CMD_FUNC_TEXT so that
command functions will be static instead of global. Remove
declarations for config_exit and config_help. Define new macros
DEFUNSH_ATTR, DEFUNSH_HIDDEN, and DEFUNSH_DEPRECATED so we can
have deprecated commands in vtysh. Similarly, for completeness,
define macros ALIAS_SH, ALIAS_SH_HIDDEN, and ALIAS_SH_DEPRECATED.
Also, fix bug in ALIAS_ATTR macro (didn't matter because it
was never used).
* command.c: Make many functions static instead of global.
(facility_name,facility_match,level_match) New functions
to support enhanced destination-specific logging levels.
(config_write_host) Support new destination-specific logging levels.
(config_logmsg) Added new "logmsg" command to help test logging
system.
(show_logging) Added "show logging" command to show the current
configuration of the logging system.
(config_log_stdout_level) Support explicit stdout logging level.
(no_config_log_stdout) Now takes optional LEVEL arg.
(config_log_monitor,config_log_monitor_level,no_config_log_monitor)
New commands creating new "log monitor" commands to set terminal
monitoring log level.
(config_log_file_level) Support explicit file logging level.
(config_log_syslog_level) Support explicit syslog logging level.
(config_log_facility,no_config_log_facility) Implement new
"log facility" command.
(cmd_init) Add hooks for new commands: "show logging", "logmsg",
"log stdout <level>", "log monitor", "log monitor <level>",
"no log monitor", "log file <filename> <level>",
"no log file <filename> <level>", "log syslog <level>",
"log facility", and "no log facility".
* vty.h: Added a "level" argument to vty_log so it can support
"log record-priority". Declare new function vty_log_fixed for
use in signal handlers.
* vty.c: (vty_log,vty_log_out) Added a "level" argument to support
"log record-priority" for vty terminal monitors.
(vty_down_level) Use config_exit_cmd.func instead of calling
config_exit directly (since command functions will now be static
instead of global).
(vty_log_fixed) New function to send terminal monitor messages
from inside a signal handler.
