- * g_desktop_app_info_new:

- *
- * Creates a new #GDesktopAppInfo based on a desktop file id.
- *
- * A desktop file id is the basename of the desktop file, including the
- * .desktop extension. GIO is looking for a desktop file with this name
- * in the <filename>applications</filename> subdirectories of the XDG data
- * directories (i.e. the directories specified in the
- * <envar>XDG_DATA_HOME</envar> and <envar>XDG_DATA_DIRS</envar> environment
- * variables). GIO also supports the prefix-to-subdirectory mapping that is
- * described in the <ulink url="http://standards.freedesktop.org/menu-spec/latest/">Menu Spec</ulink>
- * (i.e. a desktop id of kde-foo.desktop will match
- * <filename>/usr/share/applications/kde/foo.desktop</filename>).
- *
- * Returns: a new #GDesktopAppInfo, or %NULL if no desktop file with that id
+/* Search global state {{{2
+ *
+ * We only ever search under a global lock, so we can use (and reuse)
+ * some global data to reduce allocations made while searching.
+ *
+ * In short, we keep around arrays of results that we expand as needed
+ * (and never shrink).
+ *
+ * static_token_results: this is where we append the results for each
+ * token within a given desktop directory, as we handle it (which is
+ * a union of all matches for this term)
+ *
+ * static_search_results: this is where we build the complete results
+ * for a single directory (which is an intersection of the matches
+ * found for each term)
+ *
+ * static_total_results: this is where we build the complete results
+ * across all directories (which is a union of the matches found in
+ * each directory)
+ *
+ * The app_names that enter these tables are always pointer-unique (in
+ * the sense that string equality is the same as pointer equality).
+ * This can be guaranteed for two reasons:
+ *
+ * - we mask appids so that a given appid will only ever appear within
+ * the highest-precedence directory that contains it. We never
+ * return search results from a lower-level directory if a desktop
+ * file exists in a higher-level one.
+ *
+ * - within a given directory, the string is unique because it's the
+ * key in the hashtable of all app_ids for that directory.
+ *
+ * We perform a merging of the results in merge_token_results(). This
+ * works by ordering the two lists and moving through each of them (at
+ * the same time) looking for common elements, rejecting uncommon ones.
+ * "Order" here need not mean any particular thing, as long as it is
+ * some order. Because of the uniqueness of our strings, we can use
+ * pointer order. That's what's going on in compare_results() below.

* This function performs the equivalent of g_app_info_launch_uris(),

* g_app_info_launch_uris().
*
- * In contrast to g_app_info_launch_uris(), all processes created will
- * always be run directly as children as if by the UNIX fork()/exec()
- * calls.
+ * If the application is launched via traditional UNIX fork()/exec()
+ * then @spawn_flags, @user_setup and @user_setup_data are used for the
+ * call to g_spawn_async(). Additionally, @pid_callback (with
+ * @pid_callback_data) will be called to inform about the PID of the
+ * created process.
*
- * This guarantee allows additional control over the exact environment
- * of the child processes, which is provided via a setup function
- * @user_setup, as well as the process identifier of each child process
- * via @pid_callback. See g_spawn_async() for more information about the
