[Libguestfs] [PATCH v6 00/41] Refactor utilities, reimplement inspection in the daemon.
v5: https://www.redhat.com/archives/libguestfs/2017-June/msg00065.html Since v5, this now implements inspection almost completely for Linux and Windows guests. Rich.

[Libguestfs] [PATCH v6 01/41] mllib: Move Visit OCaml bindings to common/mlvisit.
The ‘Visit’ module is a self-contained library with the only
dependencies being:
- the C ‘visit’ implementation
- the guestfs OCaml bindings
Move it to a separate ‘common/mlvisit’ directory.
This change is not entirely refactoring. Two other fixes are made:
- remove unsafe use of CLEANUP_FREE from a function which could
raise an OCaml exception (cleanup handlers would not be called
correctly if the exception is thrown)
- don't link directly to common/visit/visit.c, but instead use
the library (common/visit/libvisit.la)

[Libguestfs] [PATCH v6 03/41] mllib: Move Xml (libxml2) OCaml bindings to common/mlxml.
The ‘Xml’ module is a self-contained library of bindings for libxml2,
with no other dependencies.
Move it to a separate ‘common/mlxml’ directory.
This is not pure refactoring. For unclear reasons, the previous
version of ‘Xml.parse_file’ read the whole file into memory and then
called ‘xmlReadMemory’. This was quite inefficient, and unnecessary
because we could use ‘xmlReadFile’ to read and parse the file
efficiently. Changing the code to use ‘xmlReadFile’ also removes the
unnecessary dependency on ‘Common_utils.read_whole_file’.

[Libguestfs] [PATCH v6 04/41] mllib: Split ‘Common_utils’ into ‘Std_utils’ + ‘Common_utils’.
The new module ‘Std_utils’ contains only functions which are pure
OCaml and depend only on the OCaml stdlib. Therefore these functions
may be used by the generator.
The new module is moved to ‘common/mlstdutils’.
This also removes the "<stdlib>" hack, and the code which copied
the
library around.
Also ‘Guestfs_config’, ‘Libdir’ and ‘StringMap’ modules are moved
since these are essentially the same.
The bulk of this change is just updating files which use
‘open Common_utils’ to add ‘open Std_utils’ where necessary.

-(** Imperative list manipulation functions, similar to C++ STL

-
- These operate on list references, and each function modifies the

-
- [push_back xsp x] appends the element [x] to the end of the list
- [xsp]. This function is not tail-recursive.
-
- [push_front x xsp] prepends the element [x] to the head of the
- list [xsp]. (The arguments are reversed compared to the same Perl
- function, but OCaml is type safe so that's OK.)
-
- [pop_back xsp] removes the last element of the list [xsp] and
- returns it. The list is modified to become the list minus the

- [Failure "pop_back"]. This function is not tail-recursive.
-
- [pop_front xsp] removes the head element of the list [xsp] and

- If [~f] throws an exception then [~finally] is run and the

- is lost. (NB: Janestreet core {!Exn.protectx}, on which this

[Libguestfs] [PATCH v6 09/41] utils: Split out structs cleanups and printing into common/structs.
These won't be used by the daemon, so interfere with us using
common/utils in the daemon, so they are moved to a different library.

[Libguestfs] [PATCH v6 10/41] mllib, v2v: Split out OCaml utils bindings ‘common/mlutils’.
Create a module ‘C_utils’ containing functions like ‘drive_name’ and
‘shell_unquote’ which come from the C utilities.
The new directory ‘common/mlutils’ also contains the ‘Unix_utils’
wrappers around POSIX functions missing from the OCaml stdlib.

[Libguestfs] [PATCH v6 12/41] common/mlstdutils: Implement complete set of byte swapping functions.
This implements all of:
val int_of_le16 : string -> int64
val le16_of_int : int64 -> string
val int_of_be16 : string -> int64
val be16_of_int : int64 -> string
val int_of_le32 : string -> int64
val le32_of_int : int64 -> string
val int_of_be32 : string -> int64
val be32_of_int : int64 -> string
val int_of_le64 : string -> int64
val le64_of_int : int64 -> string
val int_of_be64 : string -> int64
val be64_of_int : int64 -> string
and tests.

[Libguestfs] [PATCH v6 13/41] common/mlstdutils: Implement ‘Char.mem’, ‘String.span’ and ‘String.cspan’.
Char.mem tells you if a byte is a member of a string.
String.span and String.cspan are like the C functions strspn and
strcspn.

[Libguestfs] [PATCH v6 14/41] daemon: Link guestfsd with libutils.
After the previous refactoring, we are able to link the daemon to
common/utils, and also remove some of the "duplicate" functions that
the daemon carried ("duplicate" in quotes because they were often not
exact duplicates).
It also allows us in future (but not in this commit) to move utility
functions from the daemon into libutils.

[Libguestfs] [PATCH v6 15/41] daemon: Allow parts of the daemon and APIs to be written in OCaml.
This change allows parts of the daemon to be written in the OCaml
programming language. I am using the ‘Main Program in C’ method along
with ‘-output-obj’ to create an object file from the OCaml code /
runtime, as described here:
https://caml.inria.fr/pub/docs/manual-ocaml/intfc.html
Furthermore, change the generator to allow individual APIs to be
implemented in OCaml. This is picked by setting:
impl = OCaml <ocaml_function>;
The generator creates ‘do_function’ (the same one you would have to
write by hand in C), with the function calling the named
‘ocaml_function’ and dealing with marshalling/unmarshalling the OCaml
parameters.
Note that the OCaml compiler (either ocamlc or ocamlopt) is now
required even for building from tarballs.

[Libguestfs] [PATCH v6 16/41] daemon: Reimplement ‘file’ API in OCaml.
‘file’ is a small, self-contained API which runs a single command, so
it's a good test case for reimplementing APIs.

[Libguestfs] [PATCH v6 18/41] daemon: Reimplement several devsparts APIs in OCaml.
The reimplemented APIs are:
* list_devices
* list_partitions
* part_to_dev
* part_to_partnum
* is_whole_device

[Libguestfs] [PATCH v6 22/41] daemon: Reimplement ‘mount’, ‘mount_ro’, ‘mount_options’, ‘mount_vfs’ APIs in OCaml.
Some of the oldest and most core APIs, reimplemented.
This also moves the strange ‘mount_vfs_nochroot’ function into

[Libguestfs] [PATCH v6 25/41] daemon: Reimplement ‘file_architecture’ API in OCaml.
The previously library-side ‘file_architecture’ API is reimplemented
in the daemon, in OCaml.
There are some significant differences compared to the C
implementation:
- The C code used libmagic. That is replaced by calling the ‘file’
command (because that is simpler than using the library).
- The C code had extra cases to deal with compressed files. This is
not necessary since the ‘file’ command supports the ‘-z’ option
which transparently looks inside compressed content (this is a
consequence of the change above).
This commit demonstrates a number of techniques which will be useful
for moving inspection code to the daemon:
- Moving an API from the C library to the OCaml daemon.
- Calling from one OCaml API inside the daemon to another (from
‘Filearch.file_architecture’ to ‘File.file’). This can be done and
is done with C daemon APIs but correct reply_with_error handling is
more difficult in C.
- Use of Str for regular expression matching within the appliance.

[Libguestfs] [PATCH v6 32/41] daemon: Reimplement ‘list_filesystems’ API in the daemon, in OCaml.
Move the list_filesystems API into the daemon, reimplementing it in
OCaml. Since this API makes many other API calls, it runs a lot
faster in the daemon.

[Libguestfs] [PATCH v6 41/41] UNFINISHED daemon: Reimplement most inspection APIs in the daemon, in OCaml.
Move the following APIs into the daemon, reimplemented in OCaml:
* inspect_os
* inspect_get_roots
* inspect_get_mountpoints
* inspect_get_filesystems
* inspect_get_format
* inspect_get_type
* inspect_get_distro
* inspect_get_package_format
* inspect_get_package_management
* inspect_get_product_name
* inspect_get_product_variant
* inspect_get_major_version
* inspect_get_minor_version
* inspect_get_arch
* inspect_get_hostname
* inspect_get_windows_systemroot
* inspect_get_windows_software_hive
* inspect_get_windows_system_hive
* inspect_get_windows_current_control_set
* inspect_get_drive_mappings
* inspect_is_live
* inspect_is_netinst
* inspect_is_multipart
The following inspection APIs have NOT been reimplemented in this commit:
* inspect_list_applications [deprecated]
* inspect_list_applications2
* inspect_get_icon
This also embeds the ocaml-augeas library (upstream here:
http://git.annexia.org/?p=ocaml-augeas.git;a=summary), but it's
identical to the upstream version and should remain so.

Otherwise there's a bit of confusion between two generic names such as Std_utils and Common_utils. -- Pino Toscano

Re: [Libguestfs] [PATCH v6 11/41] utils: Rename ‘guestfs-internal-frontend.h’ to ‘utils.h’.
NACK to utils.h -- in the past I've seen a couple of libraries installing public includes as utils.h. They have been fixed, but I'd like to avoid conflicts between an installed header and a project header. -- Pino Toscano
