Logger

Debug logging support

#SoupLogger watches a class@Session and logs the HTTP traffic that it generates, for debugging purposes. Many applications use an environment variable to determine whether or not to use #SoupLogger, and to determine the amount of debugging output.

To use #SoupLogger, first create a logger with soup.logger.Logger.new_, optionally configure it with soup.logger.Logger.setRequestFilter, soup.logger.Logger.setResponseFilter, and soup.logger.Logger.setPrinter, and then attach it to a session (or multiple sessions) with soup.session.Session.addFeature.

By default, the debugging output is sent to stdout, and looks something like:

> POST /unauth HTTP/1.1
> Soup-Debug-Timestamp: 1200171744
> Soup-Debug: SoupSession 1 (0x612190), SoupMessage 1 (0x617000), GSocket 1 (0x612220)
> Host: localhost
> Content-Type: text/plain
> Connection: close

&lt; HTTP/1.1 201 Created
&lt; Soup-Debug-Timestamp: 1200171744
&lt; Soup-Debug: SoupMessage 1 (0x617000)
&lt; Date: Sun, 12 Jan 2008 21:02:24 GMT
&lt; Content-Length: 0

The Soup-Debug-Timestamp line gives the time (as a time_t) when the request was sent, or the response fully received.

The Soup-Debug line gives further debugging information about the class@Session, class@Message, and gio.socket.Socket involved; the hex numbers are the addresses of the objects in question (which may be useful if you are running in a debugger). The decimal IDs are simply counters that uniquely identify objects across the lifetime of the #SoupLogger. In particular, this can be used to identify when multiple messages are sent across the same connection.

Currently, the request half of the message is logged just before the first byte of the request gets written to the network (from the signal@Message::starting signal).

The response is logged just after the last byte of the response body is read from the network (from the signal@Message::got-body or signal@Message::got-informational signal), which means that the signal@Message::got-headers signal, and anything triggered off it (such as #SoupMessage::authenticate) will be emitted *before* the response headers are actually logged.

If the response doesn't happen to trigger the signal@Message::got-body nor signal@Message::got-informational signals due to, for example, a cancellation before receiving the last byte of the response body, the response will still be logged on the event of the signal@Message::finished signal.

Functions

getMaxBodySize int getMaxBodySize(): Get the maximum body size for logger.
setMaxBodySize void setMaxBodySize(int maxBodySize): Sets the maximum body size for logger (-1 means no limit).
setPrinter void setPrinter(soup.types.LoggerPrinter printer): Sets up an alternate log printing routine, if you don't want the log to go to stdout.
setRequestFilter void setRequestFilter(soup.types.LoggerFilter requestFilter): Sets up a filter to determine the log level for a given request.
setResponseFilter void setResponseFilter(soup.types.LoggerFilter responseFilter): Sets up a filter to determine the log level for a given response.

Inherited Members

From ObjectG

setGObject void setGObject(void* cObj, Flag!"Take" take): Set the GObject of a D ObjectG wrapper.
cPtr void* cPtr(Flag!"Dup" dup): Get a pointer to the underlying C object.
ref_ void* ref_(void* gObj): Calls g_object_ref() on a GObject.
unref unref(void* gObj): Calls g_object_unref() on a GObject.
getType GType getType(): Get the GType of an object.
gType GType gType [@property getter]: GObject GType property.
self ObjectG self(): Convenience method to return this cast to a type. For use in D with statements.
getDObject T getDObject(void* cptr, Flag!"Take" take): Template to get the D object from a C GObject and cast it to the given D object type.
connectSignalClosure ulong connectSignalClosure(string signalDetail, DClosure closure, Flag!"After" after): Connect a D closure to an object signal.
setProperty void setProperty(string propertyName, T val): Template for setting a GObject property.
getProperty T getProperty(string propertyName): Template for getting a GObject property.
compatControl size_t compatControl(size_t what, void* data)
bindProperty gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags): Creates a binding between source_property on source and target_property on target.
bindPropertyFull gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom): Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
forceFloating void forceFloating(): This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
freezeNotify void freezeNotify(): Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
getData void* getData(string key): Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
getProperty void getProperty(string propertyName, gobject.value.Value value): Gets a property of an object.
getQdata void* getQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
getv void getv(string[] names, gobject.value.Value[] values): Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.
isFloating bool isFloating(): Checks whether object has a floating[floating-ref] reference.
notify void notify(string propertyName): Emits a "notify" signal for the property property_name on object.
notifyByPspec void notifyByPspec(gobject.param_spec.ParamSpec pspec): Emits a "notify" signal for the property specified by pspec on object.
refSink gobject.object.ObjectG refSink(): Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.
runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setProperty void setProperty(string propertyName, gobject.value.Value value): Sets a property on an object.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
thawNotify void thawNotify(): Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
watchClosure void watchClosure(gobject.closure.Closure closure): This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
connectNotify ulong connectNotify(string detail, T callback, Flag!"After" after): Connect to Notify signal.
