◆ delete_log()

static void delete_log ( logfile_t victim)
static

Remove and free the log entry victim from the linked-list logfiles (it is probably present, but it might not be due to thread racing issues). After this function is called, the caller shouldn't refer to victim anymore.

Definition at line 822 of file log.c.

const char *  format,
va_list  ap,
size_t *  msg_len_out

int log_message_is_interesting ( int  severity,
log_domain_mask_t  domain

Referenced by log_tor_version().

◆ log_set_application_name()

void log_set_application_name ( const char *  name)

Tor uses this string to write the version number to the log file.

Definition at line 212 of file log.c.

Referenced by tor_init().

◆ log_tor_version()

static int log_tor_version ( logfile_t lf,
int  reset 
)
static

If lf refers to an actual file that we have just opened, and the file contains no data, log an "opening new logfile" message at the top.

Return -1 if the log is broken and needs to be deleted, else return 0.

Definition at line 293 of file log.c.

Referenced by add_file_log().

◆ logfile_deliver()

static void logfile_deliver ( logfile_t lf,
const char *  buf,
size_t  msg_len,
const char *  msg_after_prefix,
log_domain_mask_t  domain,
int  severity,
int *  callbacks_deferred 
)
inlinestatic

Send a message to lf. The full message, with time prefix and severity, is in buf. The message itself is in msg_after_prefix. If callbacks_deferred points to true, then we already deferred this message for pending callbacks and don't need to do it again. Otherwise, if we need to do it, do it, and set callbacks_deferred to 1.

Definition at line 482 of file log.c.

Referenced by flush_log_messages_from_startup().

◆ logfile_is_external()

static int logfile_is_external ( const logfile_t lf)

Definition at line 449 of file log.c.

Referenced by logfile_wants_message(), and tor_log_update_sigsafe_err_fds().

◆ logfile_wants_message()

int  severity,
log_domain_mask_t  domain 
)
inlinestatic

Return true iff lf would like to receive a message with the specified severity in the specified domain.

Definition at line 459 of file log.c.

Referenced by flush_log_messages_from_startup().

◆ logs_flush_sigsafe()

void logs_flush_sigsafe ( void  )

Flush the signal-safe log files.

This function is safe to call from a signal handler. It is currently called by the BUG() macros, when terminating the process on an abnormal condition.

Definition at line 796 of file log.c.

Referenced by tor_abort_().

◆ logs_free_all()

void logs_free_all ( void  )

Close all open log files, and free other static memory.

Definition at line 750 of file log.c.

◆ logs_set_domain_logging()

void logs_set_domain_logging ( int  enabled)

Set whether we report logging domains as a part of our log messages.

Definition at line 940 of file log.c.

◆ logs_set_pending_callback_callback()

void logs_set_pending_callback_callback ( pending_callback_callback  cb)

Register "cb" as the callback to call when there are new pending log callbacks to be flushed with flush_pending_log_callbacks().

Note that this callback, if present, can be invoked from any thread.

This callback must not log.

It is intentional that this function contains the name "callback" twice: it sets a "callback" to be called on the condition that there is a "pending callback".

Definition at line 973 of file log.c.

◆ logv()

STATIC void logv ( int  severity,
log_domain_mask_t  domain,
const char *  funcname,
const char *  suffix,
const char *  format,
va_list  ap 
)

Helper: sends a message to the appropriate logfiles, at loglevel severity. If provided, funcname is prepended to the message. The actual message is derived as from tor_snprintf(format,ap).

Definition at line 536 of file log.c.

Referenced by log_fn_().

◆ mark_logs_temp()

void mark_logs_temp ( void  )

Configure all log handles to be closed by close_temp_logs().

Definition at line 1137 of file log.c.

◆ parse_log_domain()

static log_domain_mask_t parse_log_domain ( const char *  domain)
static

Return a bitmask for the log domain for which domain is the name, or 0 if there is no such name.

Definition at line 1264 of file log.c.

◆ parse_log_level()

int parse_log_level ( const char *  level)

If level is a valid log severity, return the corresponding numeric value. Otherwise, return -1.

Definition at line 1220 of file log.c.

◆ parse_log_severity_config()

int parse_log_severity_config ( const char **  cfg_ptr,
log_severity_list_t severity_out 
)

Parse a log severity pattern in *cfg_ptr. Advance cfg_ptr after the end of the severityPattern. Set the value of severity_out to the parsed pattern. Return 0 on success, -1 on failure.

The syntax for a SeverityPattern is:

  SeverityPattern = *(DomainSeverity SP)* DomainSeverity
  DomainSeverity = (DomainList SP)? SeverityRange
  SeverityRange = MinSeverity ("-" MaxSeverity )?
  DomainList = "[" (SP? DomainSpec SP? ",") SP? DomainSpec "]"
  DomainSpec = "*" | Domain | "~" Domain

A missing MaxSeverity defaults to ERR. Severities and domains are case-insensitive. "~" indicates negation for a domain; negation happens last inside a DomainList. Only one SeverityRange without a DomainList is allowed per line.

Definition at line 1328 of file log.c.

◆ pending_log_message_free_()

static void pending_log_message_free_ ( pending_log_message_t msg)
