class Gio.DBusError(value)

Bases: GObject.GEnum

Error codes for the %G_DBUS_ERROR error domain.

New in version 2.26.

classmethod encode_gerror(error)[source]
Parameters:error (GLib.Error) – A GLib.Error.
Returns:A D-Bus error name (never None). Free with GLib.free().
Return type:str

Creates a D-Bus error name to use for error. If error matches a registered error (cf. Gio.DBusError.register_error()), the corresponding D-Bus error name will be returned.

Otherwise the a name of the form org.gtk.GDBus.UnmappedGError.Quark._ESCAPED_QUARK_NAME.Code_ERROR_CODE will be used. This allows other GDBus applications to map the error on the wire back to a GLib.Error using Gio.DBusError.new_for_dbus_error().

This function is typically only used in object mappings to put a GLib.Error on the wire. Regular applications should not use it.

New in version 2.26.

classmethod get_remote_error(error)[source]
Parameters:error (GLib.Error) – a GLib.Error
Returns:an allocated string or None if the D-Bus error name could not be found. Free with GLib.free().
Return type:str

Gets the D-Bus error name used for error, if any.

This function is guaranteed to return a D-Bus error name for all GLib.Errors returned from functions handling remote method calls (e.g. Gio.DBusConnection.call_finish()) unless Gio.DBusError.strip_remote_error() has been used on error.

New in version 2.26.

classmethod is_remote_error(error)[source]
Parameters:error (GLib.Error) – A GLib.Error.
Returns:True if error represents an error from a remote peer, False otherwise.
Return type:bool

Checks if error represents an error received via D-Bus from a remote peer. If so, use Gio.DBusError.get_remote_error() to get the name of the error.

New in version 2.26.

classmethod new_for_dbus_error(dbus_error_name, dbus_error_message)[source]
Parameters:
  • dbus_error_name (str) – D-Bus error name.
  • dbus_error_message (str) – D-Bus error message.
Returns:

An allocated GLib.Error. Free with GLib.Error.free().
Return type:

GLib.Error

Creates a GLib.Error based on the contents of dbus_error_name and dbus_error_message.

Errors registered with Gio.DBusError.register_error() will be looked up using dbus_error_name and if a match is found, the error domain and code is used. Applications can use Gio.DBusError.get_remote_error() to recover dbus_error_name.

If a match against a registered error is not found and the D-Bus error name is in a form as returned by Gio.DBusError.encode_gerror() the error domain and code encoded in the name is used to create the GLib.Error. Also, dbus_error_name is added to the error message such that it can be recovered with Gio.DBusError.get_remote_error().

Otherwise, a GLib.Error with the error code Gio.IOErrorEnum.DBUS_ERROR in the #G_IO_ERROR error domain is returned. Also, dbus_error_name is added to the error message such that it can be recovered with Gio.DBusError.get_remote_error().

In all three cases, dbus_error_name can always be recovered from the returned GLib.Error using the Gio.DBusError.get_remote_error() function (unless Gio.DBusError.strip_remote_error() hasn’t been used on the returned error).

This function is typically only used in object mappings to prepare GLib.Error instances for applications. Regular applications should not use it.

New in version 2.26.

classmethod quark()[source]
Return type:int
classmethod register_error(error_domain, error_code, dbus_error_name)[source]
Parameters:
  • error_domain (int) – A #GQuark for an error domain.
  • error_code (int) – An error code.
  • dbus_error_name (str) – A D-Bus error name.
Returns:

True if the association was created, False if it already exists.
Return type:

bool

Creates an association to map between dbus_error_name and GLib.Errors specified by error_domain and error_code.

This is typically done in the routine that returns the #GQuark for an error domain.

New in version 2.26.

classmethod register_error_domain(error_domain_quark_name, quark_volatile, entries)[source]
Parameters:
  • error_domain_quark_name (str) – The error domain name.
  • quark_volatile (int) – A pointer where to store the #GQuark.
  • entries ([Gio.DBusErrorEntry]) – A pointer to num_entries Gio.DBusErrorEntry struct items.

Helper function for associating a GLib.Error error domain with D-Bus error names.

New in version 2.26.

classmethod strip_remote_error(error)[source]
Parameters:error (GLib.Error) – A GLib.Error.
Returns:True if information was stripped, False otherwise.
Return type:bool

Looks for extra information in the error message used to recover the D-Bus error name and strips it if found. If stripped, the message field in error will correspond exactly to what was received on the wire.

This is typically used when presenting errors to the end user.

New in version 2.26.

classmethod unregister_error(error_domain, error_code, dbus_error_name)[source]
Parameters:
  • error_domain (int) – A #GQuark for an error domain.
  • error_code (int) – An error code.
  • dbus_error_name (str) – A D-Bus error name.
Returns:

True if the association was destroyed, False if it wasn’t found.
Return type:

bool

Destroys an association previously set up with Gio.DBusError.register_error().

class Gio.FileType(value)

Bases: GObject.GEnum

Indicates the file’s on-disk type.

On Windows systems a file will never have Gio.FileType.SYMBOLIC_LINK type; use Gio.FileInfo and Gio.FILE_ATTRIBUTE_STANDARD_IS_SYMLINK to determine whether a file is a symlink or not. This is due to the fact that NTFS does not have a single filesystem object type for symbolic links - it has files that symlink to files, and directories that symlink to directories. Gio.FileType enumeration cannot precisely represent this important distinction, which is why all Windows symlinks will continue to be reported as Gio.FileType.REGULAR or Gio.FileType.DIRECTORY.

Error codes returned by GIO functions.

Note that this domain may be extended in future GLib releases. In general, new error codes either only apply to new APIs, or else replace Gio.IOErrorEnum.FAILED in cases that were not explicitly distinguished before. You should therefore avoid writing code like

if (g_error_matches (error, G_IO_ERROR, G_IO_ERROR_FAILED))
{
  // Assume that this is EPRINTERONFIRE
  ...
}

but should instead treat all unrecognized error codes the same as Gio.IOErrorEnum.FAILED.

See also Gio.PollableReturn for a cheaper way of returning Gio.IOErrorEnum.WOULD_BLOCK to callers without allocating a GLib.Error.

Broken pipe.

New in version 2.36.

CONNECTION_CLOSED = 44

Connection closed by peer. Note that this is the same code as Gio.IOErrorEnum.BROKEN_PIPE; before 2.44 some “connection closed” errors returned Gio.IOErrorEnum.BROKEN_PIPE, but others returned Gio.IOErrorEnum.FAILED. Now they should all return the same value, which has this more logical name.

if (warning_level > G_MEMORY_MONITOR_WARNING_LEVEL_LOW)
drop_caches ();

New in version 2.64.

MEDIUM = 100

Same as Gio.MemoryMonitorWarningLevel.LOW but the device has even less free memory, so processes should try harder to free up unneeded resources. If your process does not need to stay running, it is a good time for it to quit.

CRITICAL = 255

The system will soon start terminating processes to reclaim memory, including background processes.

LOW = 50

Memory on the device is low, processes should free up unneeded resources (for example, in-memory caches) so they can be used elsewhere.

class Gio.MountOperationResult(value)

Bases: GObject.GEnum

Gio.MountOperationResult is returned as a result when a request for information is send by the mounting operation.

the default priority, to be used for the majority of notifications (for example email messages, software updates, completed download/sync operations)

LOW = 1

for notifications that do not require immediate attention - typically used for contextual background information, such as contact birthdays or local weather

HIGH = 2

for events that require more attention, usually because responses are time-sensitive (for example chat and SMS messages or alarms)

URGENT = 3

for urgent notifications, or notifications that require a response in a short space of time (for example phone calls or emergency warnings)

class Gio.PasswordSave(value)

Bases: GObject.GEnum

Gio.PasswordSave is used to indicate the lifespan of a saved password.

#Gvfs stores passwords in the Gnome keyring when this flag allows it to, and later retrieves it again from there.

PERMANENTLY = 2

save a password permanently.

class Gio.PollableReturn(value)

Bases: GObject.GEnum

Return value for various IO operations that signal errors via the return value and not necessarily via a GLib.Error.

This enum exists to be able to return errors to callers without having to allocate a GLib.Error. Allocating GLib.Errors can be quite expensive for regularly happening errors like Gio.IOErrorEnum.WOULD_BLOCK.

unknown error

class Gio.ResolverRecordType(value)

Bases: GObject.GEnum

The type of record that Gio.Resolver.lookup_records() or Gio.Resolver.lookup_records_async() should retrieve. The records are returned as lists of GLib.Variant tuples. Each record type has different values in the variant tuples returned.

Gio.ResolverRecordType.SRV records are returned as variants with the signature (qqqs), containing a guint16 with the priority, a guint16 with the weight, a guint16 with the port, and a string of the hostname.

Gio.ResolverRecordType.MX records are returned as variants with the signature (qs), representing a guint16 with the preference, and a string containing the mail exchanger hostname.

Gio.ResolverRecordType.TXT records are returned as variants with the signature (as), representing an array of the strings in the text record. Note: Most TXT records only contain a single string, but RFC 1035 does allow a record to contain multiple strings. The RFC which defines the interpretation of a specific TXT record will likely require concatenation of multiple strings if they are present, as with RFC 7208.

Gio.ResolverRecordType.SOA records are returned as variants with the signature (ssuuuuu), representing a string containing the primary name server, a string containing the administrator, the serial as a guint32, the refresh interval as a guint32, the retry interval as a guint32, the expire timeout as a guint32, and the TTL as a guint32.

Gio.ResolverRecordType.NS records are returned as variants with the signature (s), representing a string of the hostname of the name server.

The type of name used by a Gio.UnixSocketAddress. Gio.UnixSocketAddressType.PATH indicates a traditional unix domain socket bound to a filesystem path. Gio.UnixSocketAddressType.ANONYMOUS indicates a socket not bound to any name (eg, a client-side socket, or a socket created with socketpair()).

For abstract sockets, there are two incompatible ways of naming them; the man pages suggest using the entire struct sockaddr_un as the name, padding the unused parts of the %sun_path field with zeroes; this corresponds to Gio.UnixSocketAddressType.ABSTRACT_PADDED. However, many programs instead just use a portion of %sun_path, and pass an appropriate smaller length to bind() or connect(). This is Gio.UnixSocketAddressType.ABSTRACT.
