As osinfo_tree_create_from_location() handles non-local requests, it'd end up relying on GVFS under the hood, which would cause this API to not work when called from an app running as root. In order to avoid this situation, let's rely on libsoup for this cases. It's important to mention that glib minimum version has been bumped to 2.44 as that's the version where g_input_stream_read_all_async() has been introuced. https://gitlab.com/libosinfo/libosinfo/issues/30 Signed-off-by: Fabiano Fidêncio <fidencio@xxxxxxxxxx> --- configure.ac | 4 +- osinfo/libosinfo.syms | 2 + osinfo/osinfo_tree.c | 106 ++++++++++++++++++++++++++++++------------ osinfo/osinfo_tree.h | 11 +++++ 4 files changed, 90 insertions(+), 33 deletions(-) diff --git a/configure.ac b/configure.ac index 02ea1df..0fde62c 100644 --- a/configure.ac +++ b/configure.ac @@ -37,8 +37,8 @@ m4_if(m4_version_compare([2.61a.100], m4_ifdef([AM_SILENT_RULES],[AM_SILENT_RULES([yes])]) # Keep these two definitions in agreement. -GLIB_MINIMUM_VERSION="2.38" -GLIB_ENCODED_VERSION="GLIB_VERSION_2_38" +GLIB_MINIMUM_VERSION="2.44" +GLIB_ENCODED_VERSION="GLIB_VERSION_2_44" PKG_CHECK_MODULES([LIBXML], [libxml-2.0 >= 2.6.0]) PKG_CHECK_MODULES([LIBXSLT], [libxslt >= 1.0.0]) diff --git a/osinfo/libosinfo.syms b/osinfo/libosinfo.syms index 016d167..6d81e48 100644 --- a/osinfo/libosinfo.syms +++ b/osinfo/libosinfo.syms @@ -595,6 +595,8 @@ LIBOSINFO_1.6.0 { osinfo_media_is_bootable; osinfo_os_get_kernel_url_argument; + + osinfo_tree_error_get_type; } LIBOSINFO_1.5.0; /* Symbols in next release... diff --git a/osinfo/osinfo_tree.c b/osinfo/osinfo_tree.c index c0ec7e4..2fe8b4c 100644 --- a/osinfo/osinfo_tree.c +++ b/osinfo/osinfo_tree.c @@ -30,10 +30,14 @@ #include <stdlib.h> #include <string.h> #include <glib/gi18n-lib.h> +#include <libsoup/soup.h> typedef struct _CreateFromLocationAsyncData CreateFromLocationAsyncData; struct _CreateFromLocationAsyncData { - GFile *file; + SoupSession *session; + SoupMessage *message; + + gchar *content; gchar *location; gchar *treeinfo; @@ -42,7 +46,8 @@ struct _CreateFromLocationAsyncData { static void create_from_location_async_data_free(CreateFromLocationAsyncData *data) { - g_object_unref(data->file); + g_object_unref(data->session); + g_object_unref(data->message); g_object_unref(data->res); g_slice_free(CreateFromLocationAsyncData, data); @@ -455,7 +460,7 @@ static void on_tree_create_from_location_ready(GObject *source_object, * @error: The location where to store any error, or %NULL * * Creates a new #OsinfoTree for installation tree at @location.
