telepathy-glib has an internal mechanism for debug messages and filtering.
Connection managers written with telepathy-glib are expected to connect
this to their own debugging mechanisms: when the CM's debugging mechanism
is activated, it should call tp_debug_set_flags()
and/or
tp_debug_set_persistent()
.
The supported debug-mode keywords and the debug messages that they enable are subject to change, but currently include:
misc
- low-level utility codemanager
-
TpConnectionManager (client)connection
- TpBaseConnection (service)
and TpConnection (client)contacts
- TpContact objects
(client)channel
- TpChannel (client)im
- (text) instant messaging
(service)properties
-
TpDBusPropertiesMixin and TpPropertiesMixin (service)params
- connection manager parameters
(service)handles
- handle reference tracking tracking
in TpBaseConnection (service) and TpConnection (client)accounts
- the TpAccountManager and
TpAccount objects (client)contact-lists
- the TpBaseContactList
(service)debugger
- TpDebugClient objectstls
- TpTLSCertificate objects
(client)all
- all of the above
void tp_debug_set_flags (const gchar *flags_string
);
Set the debug flags indicated by flags_string
, in addition to any already
set.
The parsing matches that of g_parse_debug_string()
.
If telepathy-glib was compiled with --disable-debug (not recommended), this function has no practical effect, since the debug messages it would enable were removed at compile time.
|
The flags to set, comma-separated. If NULL or empty,
no additional flags are set. |
Since 0.6.1
void tp_debug_set_persistent (gboolean persistent
);
Used to enable persistent operation of the connection manager process for debugging purposes.
|
TRUE prevents the connection manager mainloop from exiting, FALSE enables exiting if there are no connections (the default behavior). |
void tp_debug_divert_messages (const gchar *filename
);
Open the given file for writing and duplicate its file descriptor to be used for stdout and stderr. This has the effect of closing the previous stdout and stderr, and sending all messages that would have gone there to the given file instead.
By default the file is truncated and hence overwritten each time the process is executed. Since version 0.7.14, if the filename is prefixed with '+' then the file is not truncated and output is added at the end of the file.
Passing NULL
to this function is guaranteed to have no effect. This is
so you can call it with the recommended usage
tp_debug_divert_messages (g_getenv ("MYAPP_LOGFILE"))
and it won't do anything if the environment variable is not set.
This function still works if telepathy-glib was compiled without debug support.
|
A file to which to divert stdout and stderr, or NULL to
do nothing |
Since 0.7.1
void tp_debug_timestamped_log_handler (const gchar *log_domain
,GLogLevelFlags log_level
,const gchar *message
,gpointer ignored
);
A GLogFunc that prepends the UTC time (currently in ISO 8601 format, with microsecond resolution) to the message, then calls g_log_default_handler.
Intended usage is:
1 2 |
if (g_getenv ("MYPROG_TIMING") != NULL) g_log_set_default_handler (tp_debug_timestamped_log_handler, NULL); |
If telepathy-glib was compiled with --disable-debug (not recommended),
this function is equivalent to g_log_default_handler()
.
Changed in 0.9.0: timestamps are now printed in UTC, in RFC-3339 format. Previously, they were printed in local time, in a format similar to RFC-3339.

Since 0.7.1
void tp_debug_set_flags_from_string (const gchar *flags_string
);
tp_debug_set_flags_from_string
is deprecated and should not be used in newly-written code. since 0.6.1. Use tp_debug_set_flags()
and
tp_debug_set_persistent()
instead
Set the debug flags indicated by flags_string
, in addition to any already
set. Unlike tp_debug_set_flags()
, this enables persistence like
tp_debug_set_persistent()
if the "persist" flag is present or the string
is "all" - this turns out to be unhelpful, as persistence should be
orthogonal.
The parsing matches that of g_parse_debug_string()
.

The flags to set, comma-separated. If NULL or empty,
no additional flags are set. |
void tp_debug_set_flags_from_env (const gchar *var
);
tp_debug_set_flags_from_env
is deprecated and should not be used in newly-written code. since 0.6.1. Use tp_debug_set_flags(g_getenv(...)) and
tp_debug_set_persistent()
instead
Equivalent to
tp_debug_set_flags_from_string (g_getenv (var))
,
and has the same problem with persistence being included in "all".
|
The name of the environment variable to parse |
void tp_debug_set_all_flags (void
);
tp_debug_set_all_flags
is deprecated and should not be used in newly-written code. since 0.6.1. Use tp_debug_set_flags ("all") and
tp_debug_set_persistent()
instead.
Activate all possible debug modes. This also activates persistent mode, which should have been orthogonal.
