Actions can be used to * expose functionality in a structured way, either from one part of a * program to another, or to the outside world. Action groups are often * used together with a #GMenuModel that provides additional * representation data for displaying the actions to the user, e.g. in * a menu. * * The main way to interact with the actions in a GActionGroup is to * activate them with g_action_group_activate_action(). Activating an * action may require a #GVariant parameter. The required type of the * parameter can be inquired with g_action_group_get_action_parameter_type(). * Actions may be disabled, see g_action_group_get_action_enabled(). * Activating a disabled action has no effect. * * Actions may optionally have a state in the form of a #GVariant. The * current state of an action can be inquired with * g_action_group_get_action_state(). Activating a stateful action may * change its state, but it is also possible to set the state by calling * g_action_group_change_action_state(). * * As typical example, consider a text editing application which has an * option to change the current font to 'bold'. A good way to represent * this would be a stateful action, with a boolean state. Activating the * action would toggle the state. * * Each action in the group has a unique name (which is a string). All * method calls, except g_action_group_list_actions() take the name of * an action as an argument. * * The #GActionGroup API is meant to be the 'public' API to the action * group. The calls here are exactly the interaction that 'external * forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have * with actions.

It wraps some * low-level platform-specific services and is intended to act as the * foundation for higher-level application classes such as * #GtkApplication or #MxApplication. In general, you should not use * this class outside of a higher level framework. * * GApplication provides convenient life cycle management by maintaining * a "use count" for the primary application instance. The use count can * be changed using g_application_hold() and g_application_release(). If * it drops to zero, the application exits. Higher-level classes such as * #GtkApplication employ the use count to ensure that the application * stays alive as long as it has any opened windows. * * Another feature that GApplication (optionally) provides is process * uniqueness. Applications can make use of this functionality by * providing a unique application ID. If given, only one application * with this ID can be running at a time per session. The session * concept is platform-dependent, but corresponds roughly to a graphical * desktop login. When your application is launched again, its * arguments are passed through platform communication to the already * running program. The already running instance of the program is * called the "primary instance"; for non-unique applications this is * the always the current instance. On Linux, the D-Bus session bus * is used for communication. * * The use of #GApplication differs from some other commonly-used * uniqueness libraries (such as libunique) in important ways. The * application is not expected to manually register itself and check * if it is the primary instance. Instead, the main() function of a * #GApplication should do very little more than instantiating the * application instance, possibly connecting signal handlers, then * calling g_application_run(). All checks for uniqueness are done * internally. If the application is the primary instance then the * startup signal is emitted and the mainloop runs. If the application * is not the primary instance then a signal is sent to the primary * instance and g_application_run() promptly returns. See the code * examples below. * * If used, the expected form of an application identifier is very close * to that of of a * [DBus bus name](http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface). * Examples include: "com.example.MyApp", "org.example.internal-apps.Calculator". * For details on valid application identifiers, see g_application_id_is_valid(). * * On Linux, the application identifier is claimed as a well-known bus name * on the user's session bus. This means that the uniqueness of your * application is scoped to the current session. It also means that your * application may provide additional services (through registration of other * object paths) at that bus name. The registration of these object paths * should be done with the shared GDBus session bus. Note that due to the * internal architecture of GDBus, method calls can be dispatched at any time * (even if a main loop is not running). For this reason, you must ensure that * any object paths that you wish to register are registered before #GApplication * attempts to acquire the bus name of your application (which happens in * g_application_register()). Unfortunately, this means that you cannot use * g_application_get_is_remote() to decide if you want to register object paths. * * GApplication also implements the #GActionGroup and #GActionMap * interfaces and lets you easily export actions by adding them with * g_action_map_add_action(). When invoking an action by calling * g_action_group_activate_action() on the application, it is always * invoked in the primary instance. The actions are also exported on * the session bus, and GIO provides the #GDBusActionGroup wrapper to * conveniently access them remotely. GIO provides a #GDBusMenuModel wrapper * for remote access to exported #GMenuModels. * * There is a number of different entry points into a GApplication: * * - via 'Activate' (i.e. just starting the application) * * - via 'Open' (i.e. opening some files) * * - by handling a command-line * * - via activating an action * * The #GApplication::startup signal lets you handle the application * initialization for all of these in a single place. * * Regardless of which of these entry points is used to start the * application, GApplication passes some "platform data from the * launching instance to the primary instance, in the form of a * #GVariant dictionary mapping strings to variants. To use platform * data, override the @before_emit or @after_emit virtual functions * in your #GApplication subclass. When dealing with * #GApplicationCommandLine objects, the platform data is * directly available via g_application_command_line_get_cwd(), * g_application_command_line_get_environ() and * g_application_command_line_get_platform_data(). * * As the name indicates, the platform data may vary depending on the * operating system, but it always includes the current directory (key * "cwd"), and optionally the environment (ie the set of environment * variables and their values) of the calling process (key "environ"). * The environment is only added to the platform data if the * %G_APPLICATION_SEND_ENVIRONMENT flag is set. #GApplication subclasses * can add their own platform data by overriding the @add_platform_data * virtual function. For instance, #GtkApplication adds startup notification * data in this way. * * To parse commandline arguments you may handle the * #GApplication::command-line signal or override the local_command_line() * vfunc, to parse them in either the primary instance or the local instance, * respectively. * * For an example of opening files with a GApplication, see * [gapplication-example-open.c](https://git.gnome.org/browse/glib/tree/gio/tests/gapplication-example-open.c). * * For an example of using actions with GApplication, see * [gapplication-example-actions.c](https://git.gnome.org/browse/glib/tree/gio/tests/gapplication-example-actions.c). * * For an example of using extra D-Bus hooks with GApplication, see * [gapplication-example-dbushooks.c](https://git.gnome.org/browse/glib/tree/gio/tests/gapplication-example-dbushooks.c). */ /** * SECTION:gapplicationcommandline * @title: GApplicationCommandLine * @short_description: A command-line invocation of an application * @include: gio/gio.h * @see_also: #GApplication * * #GApplicationCommandLine represents a command-line invocation of * an application.

It is necessary to understand that * #GFile objects do not represent files, merely an identifier for a * file. All file content I/O is implemented as streaming operations * (see #GInputStream and #GOutputStream). * * To construct a #GFile, you can use: * - g_file_new_for_path() if you have a path. * - g_file_new_for_uri() if you have a URI. * - g_file_new_for_commandline_arg() for a command line argument. * - g_file_new_tmp() to create a temporary file from a template. * - g_file_parse_name() from a UTF-8 string gotten from g_file_get_parse_name(). * * One way to think of a #GFile is as an abstraction of a pathname. For * normal files the system pathname is what is stored internally, but as * #GFiles are extensible it could also be something else that corresponds * to a pathname in a userspace implementation of a filesystem. * * #GFiles make up hierarchies of directories and files that correspond to * the files on a filesystem. You can move through the file system with * #GFile using g_file_get_parent() to get an identifier for the parent * directory, g_file_get_child() to get a child within a directory, * g_file_resolve_relative_path() to resolve a relative path between two * #GFiles. There can be multiple hierarchies, so you may not end up at * the same root if you repeatedly call g_file_get_parent() on two different * files. * * All #GFiles have a basename (get with g_file_get_basename()). These names * are byte strings that are used to identify the file on the filesystem * (relative to its parent directory) and there is no guarantees that they * have any particular charset encoding or even make any sense at all. If * you want to use filenames in a user interface you should use the display * name that you can get by requesting the * %G_FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with g_file_query_info(). * This is guaranteed to be in UTF-8 and can be used in a user interface. * But always store the real basename or the #GFile to use to actually * access the file, because there is no way to go from a display name to * the actual name. * * Using #GFile as an identifier has the same weaknesses as using a path * in that there may be multiple aliases for the same file. For instance, * hard or soft links may cause two different #GFiles to refer to the same * file. Other possible causes for aliases are: case insensitive filesystems, * short and long names on FAT/NTFS, or bind mounts in Linux. If you want to * check if two #GFiles point to the same file you can query for the * %G_FILE_ATTRIBUTE_ID_FILE attribute. Note that #GFile does some trivial * canonicalization of pathnames passed in, so that trivial differences in * the path string used at creation (duplicated slashes, slash at end of * path, "." or ".." path segments, etc) does not create different #GFiles. * * Many #GFile operations have both synchronous and asynchronous versions * to suit your application. Asynchronous versions of synchronous functions * simply have _async() appended to their function names. The asynchronous * I/O functions call a #GAsyncReadyCallback which is then used to finalize * the operation, producing a GAsyncResult which is then passed to the * function's matching _finish() operation. * * Some #GFile operations do not have synchronous analogs, as they may * take a very long time to finish, and blocking may leave an application * unusable. Notable cases include: * - g_file_mount_mountable() to mount a mountable file. * - g_file_unmount_mountable_with_operation() to unmount a mountable file. * - g_file_eject_mountable_with_operation() to eject a mountable file. * * ## Entity Tags # {#gfile-etag} * * One notable feature of #GFiles are entity tags, or "etags" for * short. Entity tags are somewhat like a more abstract version of the * traditional mtime, and can be used to quickly determine if the file * has been modified from the version on the file system. See the * HTTP 1.1 * [specification](http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html) * for HTTP Etag headers, which are a very similar concept. */ /** * SECTION:gfileattribute * @short_description: Key-Value Paired File Attributes * @include: gio/gio.h * @see_also: #GFile, #GFileInfo * * File attributes in GIO consist of a list of key-value pairs. * * Keys are strings that contain a key namespace and a key name, separated * by a colon, e.g. "namespace::keyname".

Used to check if a user has the * proper privileges to access files and perform file operations. Keys in * this namespace are made to be generic and easily understood, e.g. the * "can_read" key is %TRUE if the current user has permission to read the * file. UNIX permissions and NTFS ACLs in Windows should be mapped to * these values. * - `"mountable"`: The "Mountable" namespace. Includes simple boolean keys * for checking if a file or path supports mount operations, e.g. mount, * unmount, eject. These are used for files of type %G_FILE_TYPE_MOUNTABLE. * - `"time"`: The "Time" namespace. Includes file access, changed, created * times. * - `"unix"`: The "Unix" namespace. Includes UNIX-specific information and * may not be available for all files. Examples include the UNIX "UID", * "GID", etc. * - `"dos"`: The "DOS" namespace. Includes DOS-specific information and may * not be available for all files. Examples include "is_system" for checking * if a file is marked as a system file, and "is_archive" for checking if a * file is marked as an archive file. * - `"owner"`: The "Owner" namespace. Includes information about who owns a * file. May not be available for all file systems. Examples include "user" * for getting the user name of the file owner. This information is often * mapped from some backend specific data such as a UNIX UID. * - `"thumbnail"`: The "Thumbnail" namespace. Includes information about file * thumbnails and their location within the file system. Examples of keys in * this namespace include "path" to get the location of a thumbnail, "failed" * to check if thumbnailing of the file failed, and "is-valid" to check if * the thumbnail is outdated. * - `"filesystem"`: The "Filesystem" namespace. Gets information about the * file system where a file is located, such as its type, how much space is * left available, and the overall size of the file system. * - `"gvfs"`: The "GVFS" namespace. Keys in this namespace contain information * about the current GVFS backend in use. * - `"xattr"`: The "xattr" namespace. Gets information about extended * user attributes. See attr(5). The "user." prefix of the extended user * attribute name is stripped away when constructing keys in this namespace, * e.g. "xattr::mime_type" for the extended attribute with the name * "user.mime_type". Note that this information is only available if * GLib has been built with extended attribute support. * - `"xattr-sys"`: The "xattr-sys" namespace.

The items are associated with actions, which can be * activated through them. Items can be grouped in sections, and may * have submenus associated with them. Both items and sections usually * have some representation data, such as labels or icons. The type of * the associated action (ie whether it is stateful, and what kind of * state it has) can influence the representation of the item. * * The conceptual model of menus in #GMenuModel is hierarchical: * sections and submenus are again represented by #GMenuModels. * Menus themselves do not define their own roles. Rather, the role * of a particular #GMenuModel is defined by the item that references * it (or, in the case of the 'root' menu, is defined by the context * in which it is used). * * As an example, consider the visible portions of this menu: * * ## An example menu # {#menu-example} * * ![](menu-example.png) * * There are 8 "menus" visible in the screenshot: one menubar, two * submenus and 5 sections: * * - the toplevel menubar (containing 4 items) * - the View submenu (containing 3 sections) * - the first section of the View submenu (containing 2 items) * - the second section of the View submenu (containing 1 item) * - the final section of the View submenu (containing 1 item) * - the Highlight Mode submenu (containing 2 sections) * - the Sources section (containing 2 items) * - the Markup section (containing 2 items) * * The [example][menu-model] illustrates the conceptual connection between * these 8 menus. Each large block in the figure represents a menu and the * smaller blocks within the large block represent items in that menu. Some * items contain references to other menus. * * ## A menu example # {#menu-model} * * ![](menu-model.png) * * Notice that the separators visible in the [example][menu-example] * appear nowhere in the [menu model][menu-model]. This is because * separators are not explicitly represented in the menu model. Instead, * a separator is inserted between any two non-empty sections of a menu. * Section items can have labels just like any other item. In that case, * a display system may show a section header instead of a separator. * * The motivation for this abstract model of application controls is * that modern user interfaces tend to make these controls available * outside the application. Examples include global menus, jumplists, * dash boards, etc. To support such uses, it is necessary to 'export' * information about actions and their representation in menus, which * is exactly what the [GActionGroup exporter][gio-GActionGroup-exporter] * and the [GMenuModel exporter][gio-GMenuModel-exporter] do for * #GActionGroup and #GMenuModel. The client-side counterparts to * make use of the exported information are #GDBusActionGroup and * #GDBusMenuModel. * * The API of #GMenuModel is very generic, with iterators for the * attributes and links of an item, see g_menu_model_iterate_item_attributes() * and g_menu_model_iterate_item_links(). The 'standard' attributes and * link types have predefined names: %G_MENU_ATTRIBUTE_LABEL, * %G_MENU_ATTRIBUTE_ACTION, %G_MENU_ATTRIBUTE_TARGET, %G_MENU_LINK_SECTION * and %G_MENU_LINK_SUBMENU. * * Items in a #GMenuModel represent active controls if they refer to * an action that can get activated when the user interacts with the * menu item. The reference to the action is encoded by the string id * in the %G_MENU_ATTRIBUTE_ACTION attribute. An action id uniquely * identifies an action in an action group. Which action group(s) provide * actions depends on the context in which the menu model is used. * E.g. when the model is exported as the application menu of a * #GtkApplication, actions can be application-wide or window-specific * (and thus come from two different action groups). By convention, the * application-wide actions have names that start with "app.", while the * names of window-specific actions start with "win.". * * While a wide variety of stateful actions is possible, the following * is the minimum that is expected to be supported by all users of exported * menu information: * - an action with no parameter type and no state * - an action with no parameter type and boolean state * - an action with string parameter type and string state * * ## Stateless * * A stateless action typically corresponds to an ordinary menu item. * * Selecting such a menu item will activate the action (with no parameter). * * ## Boolean State * * An action with a boolean state will most typically be used with a "toggle" * or "switch" menu item. The state can be set directly, but activating the * action (with no parameter) results in the state being toggled. * * Selecting a toggle menu item will activate the action. The menu item should * be rendered as "checked" when the state is true. * * ## String Parameter and State * * Actions with string parameters and state will most typically be used to * represent an enumerated choice over the items available for a group of * radio menu items. Activating the action with a string parameter is * equivalent to setting that parameter as the state. * * Radio menu items, in addition to being associated with the action, will * have a target value. Selecting that menu item will result in activation * of the action with the target value as the parameter. The menu item should * be rendered as "selected" when the state of the action is equal to the * target value of the menu item. */ /** * SECTION:gmount * @short_description: Mount management * @include: gio/gio.h * @see_also: GVolume, GUnixMountEntry, GUnixMountPoint * * The #GMount interface represents user-visible mounts.

For instance * #GtkBuilder .ui files, splashscreen images, GMenu markup xml, CSS files, * icons, etc. These are often shipped as files in `$datadir/appname`, or * manually included as literal strings in the code. * * The #GResource API and the [glib-compile-resources][glib-compile-resources] program * provide a convenient and efficient alternative to this which has some nice properties. You * maintain the files as normal files, so its easy to edit them, but during the build the files * are combined into a binary bundle that is linked into the executable. This means that loading * the resource files are efficient (as they are already in memory, shared with other instances) and * simple (no need to check for things like I/O errors or locate the files in the filesystem). It * also makes it easier to create relocatable applications. * * Resource files can also be marked as compressed. Such files will be included in the resource bundle * in a compressed form, but will be automatically uncompressed when the resource is used. This * is very useful e.g. for larger text files that are parsed once (or rarely) and then thrown away. * * Resource files can also be marked to be preprocessed, by setting the value of the * `preprocess` attribute to a comma-separated list of preprocessing options. * The only options currently supported are: * * `xml-stripblanks` which will use the xmllint command * to strip ignorable whitespace from the xml file. For this to work, * the `XMLLINT` environment variable must be set to the full path to * the xmllint executable, or xmllint must be in the `PATH`; otherwise * the preprocessing step is skipped. * * `to-pixdata` which will use the gdk-pixbuf-pixdata command to convert * images to the GdkPixdata format, which allows you to create pixbufs directly using the data inside * the resource file, rather than an (uncompressed) copy if it. For this, the gdk-pixbuf-pixdata * program must be in the PATH, or the `GDK_PIXBUF_PIXDATA` environment variable must be * set to the full path to the gdk-pixbuf-pixdata executable; otherwise the resource compiler will * abort. * * Resource bundles are created by the [glib-compile-resources][glib-compile-resources] program * which takes an xml file that describes the bundle, and a set of files that the xml references. These * are combined into a binary resource bundle. * * An example resource description: * |[ * * * * data/splashscreen.png * dialog.ui * menumarkup.xml * * * ]| * * This will create a resource bundle with the following files: * |[ * /org/gtk/Example/data/splashscreen.png * /org/gtk/Example/dialog.ui * /org/gtk/Example/menumarkup.xml * ]| * * Note that all resources in the process share the same namespace, so use java-style * path prefixes (like in the above example) to avoid conflicts. * * You can then use [glib-compile-resources][glib-compile-resources] to compile the xml to a * binary bundle that you can load with g_resource_load(). However, its more common to use the --generate-source and * --generate-header arguments to create a source file and header to link directly into your application. * * Once a #GResource has been created and registered all the data in it can be accessed globally in the process by * using API calls like g_resources_open_stream() to stream the data or g_resources_lookup_data() to get a direct pointer * to the data. You can also use uris like "resource:///org/gtk/Example/data/splashscreen.png" with #GFile to access * the resource data. * * There are two forms of the generated source, the default version uses the compiler support for constructor * and destructor functions (where available) to automatically create and register the #GResource on startup * or library load time. If you pass --manual-register two functions to register/unregister the resource is instead * created. This requires an explicit initialization call in your application/library, but it works on all platforms, * even on the minor ones where this is not available. (Constructor support is available for at least Win32, MacOS and Linux.) * * Note that resource data can point directly into the data segment of e.g. a library, so if you are unloading libraries * during runtime you need to be very careful with keeping around pointers to data from a resource, as this goes away * when the library is unloaded.

Reading * settings with #GSettings is typically extremely fast: on * approximately the same order of magnitude (but slower than) a * #GHashTable lookup. Writing settings is also extremely fast in terms * of time to return to your application, but can be extremely expensive * for other threads and other processes. Many settings backends * (including dconf) have lazy initialisation which means in the common * case of the user using their computer without modifying any settings * a lot of work can be avoided. For dconf, the D-Bus service doesn't * even need to be started in this case. For this reason, you should * only ever modify #GSettings keys in response to explicit user action. * Particular care should be paid to ensure that modifications are not * made during startup -- for example, when setting the initial value * of preferences widgets. The built-in g_settings_bind() functionality * is careful not to write settings in response to notify signals as a * result of modifications that it makes to widgets. * * When creating a GSettings instance, you have to specify a schema * that describes the keys in your settings and their types and default * values, as well as some other information. * * Normally, a schema has as fixed path that determines where the settings * are stored in the conceptual global tree of settings. However, schemas * can also be 'relocatable', i.e. not equipped with a fixed path. This is * useful e.g. when the schema describes an 'account', and you want to be * able to store a arbitrary number of accounts. * * Paths must start with and end with a forward slash character ('/') * and must not contain two sequential slash characters. Paths should * be chosen based on a domain name associated with the program or * library to which the settings belong. Examples of paths are * "/org/gtk/settings/file-chooser/" and "/ca/desrt/dconf-editor/". * Paths should not start with "/apps/", "/desktop/" or "/system/" as * they often did in GConf. * * Unlike other configuration systems (like GConf), GSettings does not * restrict keys to basic types like strings and numbers. GSettings stores * values as #GVariant, and allows any #GVariantType for keys. Key names * are restricted to lowercase characters, numbers and '-'. Furthermore, * the names must begin with a lowercase character, must not end * with a '-', and must not contain consecutive dashes. * * Similar to GConf, the default values in GSettings schemas can be * localized, but the localized values are stored in gettext catalogs * and looked up with the domain that is specified in the * gettext-domain attribute of the or * elements and the category that is specified in the l10n attribute of * the element. * * GSettings uses schemas in a compact binary form that is created * by the [glib-compile-schemas][glib-compile-schemas] * utility. The input is a schema description in an XML format. * * A DTD for the gschema XML format can be found here: * [gschema.dtd](https://git.gnome.org/browse/glib/tree/gio/gschema.dtd) * * The [glib-compile-schemas][glib-compile-schemas] tool expects schema * files to have the extension `.gschema.xml`. * * At runtime, schemas are identified by their id (as specified in the * id attribute of the element). The convention for schema * ids is to use a dotted name, similar in style to a D-Bus bus name, * e.g. "org.gnome.SessionManager". In particular, if the settings are * for a specific service that owns a D-Bus bus name, the D-Bus bus name * and schema id should match. For schemas which deal with settings not * associated with one named application, the id should not use * StudlyCaps, e.g. "org.gnome.font-rendering". * * In addition to #GVariant types, keys can have types that have * enumerated types. These can be described by a , * or element, as seen in the * [example][schema-enumerated]. The underlying type of such a key * is string, but you can use g_settings_get_enum(), g_settings_set_enum(), * g_settings_get_flags(), g_settings_set_flags() access the numeric values * corresponding to the string value of enum and flags keys. * * An example for default value: * |[ * * * * * "Hello, earthlings" * A greeting * * Greeting of the invading martians * * * * * (20,30) * * * * * ]| * * An example for ranges, choices and enumerated types: * |[ * * * * * * * * * * * * * * * * * * 10 * * * * * * * * * * * * * 'Joe' * * * * 'first' * * * * ["flag1",flag2"] * * * * ]| * * ## Vendor overrides * * Default values are defined in the schemas that get installed by * an application. Sometimes, it is necessary for a vendor or distributor * to adjust these defaults. Since patching the XML source for the schema * is inconvenient and error-prone, * [glib-compile-schemas][glib-compile-schemas] reads so-called vendor * override' files. These are keyfiles in the same directory as the XML * schema sources which can override default values. The schema id serves * as the group name in the key file, and the values are expected in * serialized GVariant form, as in the following example: * |[ * [org.gtk.Example] * key1='string' * key2=1.5 * ]| * * glib-compile-schemas expects schema files to have the extension * `.gschema.override`. * * ## Binding * * A very convenient feature of GSettings lets you bind #GObject properties * directly to settings, using g_settings_bind(). Once a GObject property * has been bound to a setting, changes on either side are automatically * propagated to the other side. GSettings handles details like mapping * between GObject and GVariant types, and preventing infinite cycles. * * This makes it very easy to hook up a preferences dialog to the * underlying settings. To make this even more convenient, GSettings * looks for a boolean property with the name "sensitivity" and * automatically binds it to the writability of the bound setting. * If this 'magic' gets in the way, it can be suppressed with the * #G_SETTINGS_BIND_NO_SENSITIVITY flag. */ /** * SECTION:gsettingsbackend * @title: GSettingsBackend * @short_description: Interface for settings backend implementations * @include: gio/gsettingsbackend.h * @see_also: #GSettings, #GIOExtensionPoint * * The #GSettingsBackend interface defines a generic interface for * non-strictly-typed data that is stored in a hierarchy.

This replaces the * abuse of g_simple_async_result_set_op_res_gpointer() for the same * purpose with #GSimpleAsyncResult. * - In addition to the task data, #GTask also keeps track of the * [priority][io-priority], #GCancellable, and * #GMainContext associated with the task, so tasks that consist of * a chain of simpler asynchronous operations will have easy access * to those values when starting each sub-task. * - g_task_return_error_if_cancelled() provides simplified * handling for cancellation. In addition, cancellation * overrides any other #GTask return value by default, like * #GSimpleAsyncResult does when * g_simple_async_result_set_check_cancellable() is called. * (You can use g_task_set_check_cancellable() to turn off that * behavior.) On the other hand, g_task_run_in_thread() * guarantees that it will always run your * `task_func`, even if the task's #GCancellable * is already cancelled before the task gets a chance to run; * you can start your `task_func` with a * g_task_return_error_if_cancelled() check if you need the * old behavior. * - The "return" methods (eg, g_task_return_pointer()) * automatically cause the task to be "completed" as well, and * there is no need to worry about the "complete" vs "complete * in idle" distinction. (#GTask automatically figures out * whether the task's callback can be invoked directly, or * if it needs to be sent to another #GMainContext, or delayed * until the next iteration of the current #GMainContext.) * - The "finish" functions for #GTask-based operations are generally * much simpler than #GSimpleAsyncResult ones, normally consisting * of only a single call to g_task_propagate_pointer() or the like. * Since g_task_propagate_pointer() "steals" the return value from * the #GTask, it is not necessary to juggle pointers around to * prevent it from being freed twice. * - With #GSimpleAsyncResult, it was common to call * g_simple_async_result_propagate_error() from the * `_finish()` wrapper function, and have * virtual method implementations only deal with successful * returns. This behavior is deprecated, because it makes it * difficult for a subclass to chain to a parent class's async * methods. Instead, the wrapper function should just be a * simple wrapper, and the virtual method should call an * appropriate `g_task_propagate_` function. * Note that wrapper methods can now use * g_async_result_legacy_propagate_error() to do old-style * #GSimpleAsyncResult error-returning behavior, and * g_async_result_is_tagged() to check if a result is tagged as * having come from the `_async()` wrapper * function (for "short-circuit" results, such as when passing * 0 to g_input_stream_read_async()). */ /** * SECTION:gtcpconnection * @title: GTcpConnection * @short_description: A TCP GSocketConnection * @include: gio/gio.h * @see_also: #GSocketConnection. * * This is the subclass of #GSocketConnection that is created * for TCP/IP sockets. * * Since: 2.22 */ /** * SECTION:gtcpwrapperconnection * @title: GTcpWrapperConnection * @short_description: Wrapper for non-GSocketConnection-based, * GSocket-based GIOStreams * @include: gio/gio.h * @see_also: #GSocketConnection. * * A #GTcpWrapperConnection can be used to wrap a #GIOStream that is * based on a #GSocket, but which is not actually a * #GSocketConnection.

The #GTestDBus object makes this easier for us by taking care * of the lower level tasks such as running a private D-Bus daemon and looking * up uninstalled services in customizable locations, typically in your source * code tree. * * The first thing you will need is a separate service description file for the * D-Bus daemon. Typically a `services` subdirectory of your `tests` directory * is a good place to put this file. * * The service file should list your service along with an absolute path to the * uninstalled service executable in your source tree. Using autotools we would * achieve this by adding a file such as `my-server.service.in` in the services * directory and have it processed by configure. * |[ * [D-BUS Service] * Name=org.gtk.GDBus.Examples.ObjectManager * Exec=@abs_top_builddir@/gio/tests/gdbus-example-objectmanager-server * ]| * You will also need to indicate this service directory in your test * fixtures, so you will need to pass the path while compiling your * test cases. Typically this is done with autotools with an added * preprocessor flag specified to compile your tests such as: * |[ * -DTEST_SERVICES=\""$(abs_top_builddir)/tests/services"\" * ]| * Once you have a service definition file which is local to your source tree, * you can proceed to set up a GTest fixture using the #GTestDBus scaffolding. * * An example of a test fixture for D-Bus services can be found * here: * [gdbus-test-fixture.c](https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-test-fixture.c) * * Note that these examples only deal with isolating the D-Bus aspect of your * service. To successfully run isolated unit tests on your service you may need * some additional modifications to your test case fixture. For example; if your * service uses GSettings and installs a schema then it is important that your test service * not load the schema in the ordinary installed location (chances are that your service * and schema files are not yet installed, or worse; there is an older version of the * schema file sitting in the install location). * * Most of the time we can work around these obstacles using the * environment.

If its not possible to do any work an error is returned. * * Note that a single call may not consume all input (or any input at all). * Also a call may produce output even if given no input, due to state stored * in the converter producing output. * * If any data was either produced or consumed, and then an error happens, then * only the successful conversion is reported and the error is returned on the * next call. * * A full conversion loop involves calling this method repeatedly, each time * giving it new input and space output space. When there is no more input * data after the data in @inbuf, the flag %G_CONVERTER_INPUT_AT_END must be set. * The loop will be (unless some error happens) returning %G_CONVERTER_CONVERTED * each time until all data is consumed and all output is produced, then * %G_CONVERTER_FINISHED is returned instead. Note, that %G_CONVERTER_FINISHED * may be returned even if %G_CONVERTER_INPUT_AT_END is not set, for instance * in a decompression converter where the end of data is detectable from the * data (and there might even be other data after the end of the compressed data). * * When some data has successfully been converted @bytes_read and is set to * the number of bytes read from @inbuf, and @bytes_written is set to indicate * how many bytes was written to @outbuf. If there are more data to output * or consume (i.e. unless the %G_CONVERTER_INPUT_AT_END is specified) then * %G_CONVERTER_CONVERTED is returned, and if no more data is to be output * then %G_CONVERTER_FINISHED is returned. * * On error %G_CONVERTER_ERROR is returned and @error is set accordingly. * Some errors need special handling: * * %G_IO_ERROR_NO_SPACE is returned if there is not enough space * to write the resulting converted data, the application should * call the function again with a larger @outbuf to continue. * * %G_IO_ERROR_PARTIAL_INPUT is returned if there is not enough * input to fully determine what the conversion should produce, * and the %G_CONVERTER_INPUT_AT_END flag is not set. This happens for * example with an incomplete multibyte sequence when converting text, * or when a regexp matches up to the end of the input (and may match * further input). It may also happen when @inbuf_size is zero and * there is no more data to produce. * * When this happens the application should read more input and then * call the function again. If further input shows that there is no * more data call the function again with the same data but with * the %G_CONVERTER_INPUT_AT_END flag set. This may cause the conversion * to finish as e.g. in the regexp match case (or, to fail again with * %G_IO_ERROR_PARTIAL_INPUT in e.g. a charset conversion where the * input is actually partial). * * After g_converter_convert() has returned %G_CONVERTER_FINISHED the * converter object is in an invalid state where its not allowed * to call g_converter_convert() anymore. At this time you can only * free the object or call g_converter_reset() to reset it to the * initial state. * * If the flag %G_CONVERTER_FLUSH is set then conversion is modified * to try to write out all internal state to the output. The application * has to call the function multiple times with the flag set, and when * the available input has been consumed and all internal state has * been produced then %G_CONVERTER_FLUSHED (or %G_CONVERTER_FINISHED if * really at the end) is returned instead of %G_CONVERTER_CONVERTED. * This is somewhat similar to what happens at the end of the input stream, * but done in the middle of the data. * * This has different meanings for different conversions. For instance * in a compression converter it would mean that we flush all the * compression state into output such that if you uncompress the * compressed data you get back all the input data. Doing this may * make the final file larger due to padding though. Another example * is a regexp conversion, where if you at the end of the flushed data * have a match, but there is also a potential longer match. In the * non-flushed case we would ask for more input, but when flushing we * treat this as the end of input and do the match. * * Flushing is not always possible (like if a charset converter flushes * at a partial multibyte sequence).
