[Libguestfs] [PATCH 3/3] daemon: autogenerate most of OCaml interfaces

Add a way to generate OCaml interfaces for a whilelist of modules in the daemon that implement APIs: this makes sure that for them the interface of each function matches the actual API specified in the generator. Only the modules specified in a list are generated for now, although this coverts almost all the daemon APIs implemented in OCaml. --- .gitignore | 15 ++++++++++ daemon/blkid.mli | 19 ------------ daemon/btrfs.mli | 20 ------------- daemon/devsparts.mli | 25 ---------------- daemon/file.mli | 19 ------------ daemon/filearch.mli | 19 ------------ daemon/findfs.mli | 20 ------------- daemon/inspect.mli | 41 ------------------------- daemon/is.mli | 21 ------------- daemon/ldm.mli | 20 ------------- daemon/link.mli | 19 ------------ daemon/listfs.mli | 19 ------------ daemon/md.mli | 20 ------------- daemon/parted.mli | 27 ----------------- daemon/realpath.mli | 20 ------------- daemon/statvfs.mli | 19 ------------ generator/daemon.ml | 85 ++++++++++++++++++++++++++++++++++++++++++++++++++++ generator/daemon.mli | 1 + generator/main.ml | 10 +++++++ 19 files changed, 111 insertions(+), 328 deletions(-) delete mode 100644 daemon/blkid.mli delete mode 100644 daemon/btrfs.mli delete mode 100644 daemon/devsparts.mli delete mode 100644 daemon/file.mli delete mode 100644 daemon/filearch.mli delete mode 100644 daemon/findfs.mli delete mode 100644 daemon/inspect.mli delete mode 100644 daemon/is.mli delete mode 100644 daemon/ldm.mli delete mode 100644 daemon/link.mli delete mode 100644 daemon/listfs.mli delete mode 100644 daemon/md.mli delete mode 100644 daemon/parted.mli delete mode 100644 daemon/realpath.mli delete mode 100644 daemon/statvfs.mli diff --git a/.gitignore b/.gitignore index bb7026537..6927b8bb5 100644 --- a/.gitignore +++ b/.gitignore @@ -185,21 +185,36 @@ Makefile.in /customize/virt-customize.1 /daemon/.depend /daemon/actions.h +/daemon/blkid.mli +/daemon/btrfs.mli /daemon/callbacks.ml /daemon/caml-stubs.c /daemon/daemon_config.ml /daemon/daemon_utils_tests +/daemon/devsparts.mli /daemon/dispatch.c +/daemon/file.mli +/daemon/filearch.mli +/daemon/findfs.mli /daemon/guestfsd /daemon/guestfsd.8 /daemon/guestfsd.exe +/daemon/inspect.mli +/daemon/is.mli +/daemon/ldm.mli +/daemon/link.mli +/daemon/listfs.mli /daemon/lvm-tokenization.c +/daemon/md.mli /daemon/names.c /daemon/optgroups.c /daemon/optgroups.h /daemon/optgroups.ml /daemon/optgroups.mli +/daemon/parted.mli +/daemon/realpath.mli /daemon/stamp-guestfsd.pod +/daemon/statvfs.mli /daemon/structs-cleanups.c /daemon/structs-cleanups.h /daemon/structs.ml diff --git a/daemon/blkid.mli b/daemon/blkid.mli deleted file mode 100644 index 65a61def4..000000000 --- a/daemon/blkid.mli +++ /dev/null @@ -1,19 +0,0 @@ -(* guestfs-inspection - * Copyright (C) 2009-2018 Red Hat Inc. - * - * 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.
