Detailed Description

Logging

Lws provides flexible and filterable logging facilities, which can be used inside lws and in user code.

Log categories may be individually filtered bitwise, and directed to built-in sinks for syslog-compatible logging, or a user-defined function.

Traditional logs use a single, processwide logging context. New style log apis (lws_xxx_cx()) can pass the logging context to use in.

Collaboration diagram for lws_log_cx:

Data Fields
union lws_log_cx	u
lws_log_use_cx_t	refcount_cb	NULL, or a function called after each change to .refcount below, this enables implementing side-effects like opening and closing log files when the first and last object binds / unbinds
lws_log_prepend_cx_t	prepend	NULL, or a cb to optionally prepend a string to logs we are a parent of
struct lws_log_cx *	parent	NULL, or points to log ctx we are a child of
void *	opaque	ignored by lws, used to pass config to emit_cx, eg, filepath
void *	stg	ignored by lws, may be used a storage by refcount_cb / emit_cx
uint32_t	lll_flags	mask of log levels we want to emit in this context
int32_t	refcount	refcount of objects bound to this log context

◆ lwsl_hexdump_level()

LWS_VISIBLE LWS_EXTERN void lwsl_hexdump_level	(	int	level,
		const void *	vbuf,
		size_t	len
	)

#include <include/libwebsockets/lws-logs.h>

lwsl_hexdump_level() - helper to hexdump a buffer at a selected debug level

Parameters

level	one of LLL_ constants
vbuf	buffer start to dump
len	length of buffer to dump

If level is visible, does a nice hexdump -C style dump of vbuf for len bytes. This can be extremely convenient while debugging.

◆ lwsl_hexdump_level_cx()

LWS_VISIBLE LWS_EXTERN void lwsl_hexdump_level_cx	(	lws_log_cx_t *	cx,
		lws_log_prepend_cx_t	prep,
		void *	obj,
		int	hexdump_level,
		const void *	vbuf,
		size_t	len
	)

#include <include/libwebsockets/lws-logs.h>

◆ lwsl_hexdump()

LWS_VISIBLE LWS_EXTERN void lwsl_hexdump	(	const void *	buf,
		size_t	len
	)

#include <include/libwebsockets/lws-logs.h>

lwsl_hexdump() - helper to hexdump a buffer (DEBUG builds only)

Parameters

buf	buffer start to dump
len	length of buffer to dump

Calls through to lwsl_hexdump_level(LLL_DEBUG, ... for compatability. It's better to use lwsl_hexdump_level(level, ... directly so you can control the visibility.

◆ lws_set_log_level()

LWS_VISIBLE LWS_EXTERN void lws_set_log_level	(	int	level,
		lws_log_emit_t	log_emit_function
	)

#include <include/libwebsockets/lws-logs.h>

lws_set_log_level() - Set the logging bitfield

Parameters

level	OR together the LLL_ debug contexts you want output from
log_emit_function	NULL to leave it as it is, or a user-supplied function to perform log string emission instead of the default stderr one.

log level defaults to "err", "warn" and "notice" contexts enabled and emission on stderr. If stderr is a tty (according to isatty()) then the output is coloured according to the log level using ANSI escapes.

You can set the default security level for logging using the secrecy_and_log_level() macro to set the level parameter, eg

lws_set_log_level(secrecy_and_log_level(LWS_SECRECY_PII, LLL_ERR | LLL_WARN), my_emit_function);

Normally you can just leave it at the default.

◆ lwsl_emit_syslog()

LWS_VISIBLE LWS_EXTERN void lwsl_emit_syslog	(	int	level,
		const char *	line
	)

#include <include/libwebsockets/lws-logs.h>

lwsl_emit_syslog() - helper log emit function writes to system log

Parameters

level	one of LLL_ log level indexes
line	log string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

◆ lwsl_emit_stderr()

LWS_VISIBLE LWS_EXTERN void lwsl_emit_stderr	(	int	level,
		const char *	line
	)

#include <include/libwebsockets/lws-logs.h>

lwsl_emit_stderr() - helper log emit function writes to stderr

Parameters

level	one of LLL_ log level indexes
line	log string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

It prepends a system timestamp like [2018/11/13 07:41:57:3989]

If stderr is a tty, then ansi colour codes are added.

◆ lwsl_emit_stderr_notimestamp()

LWS_VISIBLE LWS_EXTERN void lwsl_emit_stderr_notimestamp	(	int	level,
		const char *	line
	)

#include <include/libwebsockets/lws-logs.h>

lwsl_emit_stderr_notimestamp() - helper log emit function writes to stderr

Parameters

level	one of LLL_ log level indexes
line	log string

You use this by passing the function pointer to lws_set_log_level(), to set it as the log emit function, it is not called directly.

If stderr is a tty, then ansi colour codes are added.

◆ lwsl_visible()

LWS_VISIBLE LWS_EXTERN int lwsl_visible ( int level )

#include <include/libwebsockets/lws-logs.h>

lwsl_visible() - returns true if the log level should be printed

Parameters

level one of LLL_ log level indexes

This is useful if you have to do work to generate the log content, you can skip the work if the log level used to print it is not actually enabled at runtime.

◆ lws_wsi_tag()

LWS_VISIBLE LWS_EXTERN const char* lws_wsi_tag ( struct lws * wsi )

#include <include/libwebsockets/lws-logs.h>

◆ lwsl_refcount_cx()

LWS_VISIBLE LWS_EXTERN void lwsl_refcount_cx	(	lws_log_cx_t *	cx,
		int	_new
	)

#include <include/libwebsockets/lws-logs.h>
