File 0008-Reintroduce-the-builtin-metadata-manager.patch of Package mingw32-evince
From f5d612d218f7e2577f16a9f1355c555dd4258fc8 Mon Sep 17 00:00:00 2001 From: Hib Eris <hib@hiberis.nl> Date: Tue, 26 Jul 2011 11:58:18 +0200 Subject: [PATCH 08/12] Reintroduce the builtin metadata-manager On Windows, gvfs is not available, and thus Evince cannot use its metadata storage. This patch brings back Evince metadata manager from the days before gvfs. Ideally, we would not need this patch and gio/gvfs would support metadata on Windows. For now, however, weh have to uglify Evince code with this patch. --- configure.ac | 24 ++ shell/Makefile.am | 10 +- shell/ev-metadata-manager.c | 763 +++++++++++++++++++++++++++++++++++++++++++ shell/ev-metadata-manager.h | 56 ++++ shell/ev-metadata.c | 56 ++++ 5 files changed, 907 insertions(+), 2 deletions(-) create mode 100644 shell/ev-metadata-manager.c create mode 100644 shell/ev-metadata-manager.h diff --git a/configure.ac b/configure.ac index 4dfd6ed..dce6c5d 100644 --- a/configure.ac +++ b/configure.ac @@ -305,6 +305,30 @@ if test "$with_keyring" = "yes"; then AC_DEFINE([WITH_KEYRING],[1],[Define if KEYRING support is enabled]) fi +# ********************* +# Metadata support +# ********************* + +AC_MSG_CHECKING([which metadata backend to use]) +AC_ARG_WITH([metadata], + [AS_HELP_STRING([--with-metadata=gvfs|builtin], + [Setting metadata backend ])], + [case "$withval" in + gvfs|builtin) ;; + *) AC_MSG_ERROR([invalid argument "$withval" for --with-metadata]) ;; + esac], + [case "$host" in + *-*-mingw*|*-*-cygwin*) with_metadata="builtin" ;; + *) with_metadata=gvfs ;; + esac]) +AC_MSG_RESULT([$with_metadata]) + +if test "$with_metadata" = "builtin"; then + AC_DEFINE([WITH_METADATA_BUILTIN],[1],[Define to build builtin metadata support]) +fi +AM_CONDITIONAL([WITH_METADATA_BUILTIN], [test "$with_metadata" = "builtin"]) + + # **** # DBUS # **** diff --git a/shell/Makefile.am b/shell/Makefile.am index 18d75fc..7c75ceb 100644 --- a/shell/Makefile.am +++ b/shell/Makefile.am @@ -45,8 +45,8 @@ evince_SOURCES= \ ev-keyring.c \ ev-message-area.c \ ev-message-area.h \ - ev-metadata.c \ - ev-metadata.h \ + ev-metadata-manager.c \ + ev-metadata-manager.h \ ev-navigation-action.c \ ev-navigation-action.h \ ev-navigation-action-widget.c \ @@ -91,6 +91,12 @@ nodist_evince_SOURCES = \ ev-resources.c \ $(NULL) +if WITH_METADATA_BUILTIN +evince_SOURCES += \ + ev-metadata.c \ + ev-metadata.h +endif + if ENABLE_DBUS evince_SOURCES += \ ev-media-player-keys.c \ diff --git a/shell/ev-metadata-manager.c b/shell/ev-metadata-manager.c new file mode 100644 index 0000000..2c2b719 --- /dev/null +++ b/shell/ev-metadata-manager.c @@ -0,0 +1,763 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*- */ +/* + * ev-metadata-manager.c + * This file is part of ev + * + * Copyright (C) 2003 Paolo Maggi + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
