guestfs-hacking - extending and contributing to libguestfs
説明
This manual page is for hackers who want to extend libguestfs itself.
THE SOURCE CODE
Libguestfs source is located in the github repository
https://github.com/libguestfs/libguestfs
Large amounts of boilerplate code in libguestfs (RPC, bindings, documentation) are
generated. This means that many source files will appear to be missing from a
straightforward git checkout. You have to run the generator ("./autogen.sh && make -C
generator") in order to create those files.
Libguestfs uses an autotools-based build system, with the main files being configure.ac
and Makefile.am. See "THE BUILD SYSTEM".
The generator subdirectory contains the generator, plus files describing the API. The lib
subdirectory contains source for the library. The appliance and daemon subdirectories
contain the source for the code that builds the appliance, and the code that runs in the
appliance respectively. Other directories are covered in the section "SOURCE CODE
SUBDIRECTORIES" below.
Apart from the fact that all API entry points go via some generated code, the library is
straightforward. (In fact, even the generated code is designed to be readable, and should
be read as ordinary code). Some actions run entirely in the library, and are written as C
functions in files under lib. Others are forwarded to the daemon where (after some
generated RPC marshalling) they appear as C functions in files under daemon.
To build from source, first read the guestfs-building(1).
ソースコードのサブディレクトリー
There are a lot of subdirectories in the source tree! Which ones should you concentrate on
first? lib and daemon which contain the source code of the core library. generator is the
code generator described above, so that is important. The Makefile.am in the root
directory will tell you in which order the subdirectories get built. And then if you are
looking at a particular tool (eg. v2v) or language binding (eg. python), go straight to
that subdirectory, but remember that if you didn't run the generator yet, then you may
find files which appear to be missing.

THE BUILD SYSTEM
Libguestfs uses the GNU autotools build system (autoconf, automake, libtool).
The ./configure script is generated from configure.ac and m4/guestfs_*.m4. Most of the
configure script is split over many m4 macro files by topic, for example
m4/guestfs_daemon.m4 deals with the dependencies of the daemon.
The job of the top level Makefile.am is mainly to list the subdirectories ("SUBDIRS") in
the order they should be compiled.
common-rules.mk is included in every Makefile.am (top level and subdirectories).
subdir-rules.mk is included only in subdirectory Makefile.am files.
There are many make targets. Use this command to list them all:
make help
EXTENDING LIBGUESTFS
ADDING A NEW API
Because large amounts of boilerplate code in libguestfs are generated, this makes it easy
to extend the libguestfs API.
To add a new API action there are two changes:
1. You need to add a description of the call (name, parameters, return type, tests,
documentation) to generator/actions_*.ml and possibly generator/proc_nr.ml.
There are two sorts of API action, depending on whether the call goes through to the
daemon in the appliance, or is serviced entirely by the library (see "ARCHITECTURE" in
guestfs-internals(1)). "guestfs_sync" in guestfs(3) is an example of the former,
since the sync is done in the appliance. "guestfs_set_trace" in guestfs(3) is an
example of the latter, since a trace flag is maintained in the handle and all tracing
is done on the library side.
Most new actions are of the first type, and get added to the "daemon_functions" list.
Each function has a unique procedure number used in the RPC protocol which is assigned
to that action when we publish libguestfs and cannot be reused. Take the latest
procedure number and increment it.
For library-only actions of the second type, add to the "non_daemon_functions" list.
Since these functions are serviced by the library and do not travel over the RPC
mechanism to the daemon, these functions do not need a procedure number, and so the
procedure number is set to "-1".
2. Implement the action (in C):
For daemon actions, implement the function "do_<name>" in the "daemon/" directory.
For library actions, implement the function "guestfs_impl_<name>" in the "lib/"
directory.
In either case, use another function as an example of what to do.
これらの変更をした後、コンパイルするために "make" を使用してください。
Note that you don't need to implement the RPC, language bindings, manual pages or anything
else. It's all automatically generated from the OCaml description.
Adding tests for an API
You can supply zero or as many tests as you want per API call. The tests can either be
added as part of the API description (generator/actions_*.ml), or in some rarer cases you
may want to drop a script into "tests/*/". Note that adding a script to "tests/*/" is
slower, so if possible use the first method.
The following describes the test environment used when you add an API test in
actions_*.ml.
テスト環境は 4 個のブロックデバイスを持ちます:
/dev/sda 2 GB
テスト用の一般的なブロックデバイス。
/dev/sdb 2 GB
/dev/sdb1 is an ext2 filesystem used for testing filesystem write operations.
/dev/sdc 10 MB
2 つのブロックデバイスが必要となるいくつかのテストにおいて使用されます。
/dev/sdd
ISO with fixed content (see images/test.iso).
To be able to run the tests in a reasonable amount of time, the libguestfs appliance and
block devices are reused between tests. So don't try testing "guestfs_kill_subprocess" in
guestfs(3) :-x
Each test starts with an initial scenario, selected using one of the "Init*" expressions,
described in generator/types.ml. These initialize the disks mentioned above in a
particular way as documented in types.ml. You should not assume anything about the
previous contents of other disks that are not initialized.
You can add a prerequisite clause to any individual test. This is a run-time check,
which, if it fails, causes the test to be skipped. Useful if testing a command which
might not work on all variations of libguestfs builds. A test that has prerequisite of
"Always" means to run unconditionally.
In addition, packagers can skip individual tests by setting environment variables before
running "make check".
SKIP_TEST_<CMD>_<NUM>=1
eg: "SKIP_TEST_COMMAND_3=1" skips test #3 of "guestfs_command" in guestfs(3).
または:
SKIP_TEST_<CMD>=1
eg: "SKIP_TEST_ZEROFREE=1" skips all "guestfs_zerofree" in guestfs(3) tests.
Packagers can run only certain tests by setting for example:
TEST_ONLY="vfs_type zerofree"
See tests/c-api/tests.c for more details of how these environment variables work.
Debugging new APIs
Test new actions work before submitting them.
新しいコマンドを試すために guestfish を使うことができます。
Debugging the daemon is a problem because it runs inside a minimal environment. However
you can fprintf messages in the daemon to stderr, and they will show up if you use
"guestfish -v".
ADDING A NEW LANGUAGE BINDING
All language bindings must be generated by the generator (see the generator subdirectory).
There is no documentation for this yet. We suggest you look at an existing binding, eg.
generator/ocaml.ml or generator/perl.ml.
Adding tests for language bindings
Language bindings should come with tests. Previously testing of language bindings was
rather ad-hoc, but we have been trying to formalize the set of tests that every language
binding should use.
Currently only the OCaml and Perl bindings actually implement the full set of tests, and
the OCaml bindings are canonical, so you should emulate what the OCaml tests do.
This is the numbering scheme used by the tests:
- 000+ basic tests:
010 load the library
020 create
030 create-flags
040 create multiple handles
050 test setting and getting config properties
060 explicit close
065 implicit close (in GC'd languages)
070 optargs
080 version
090 retvalues
- 100 launch, create partitions and LVs and filesystems
- 400+ events:
410 close event
420 log messages
430 progress messages
- 800+ regression tests (specific to the language)
- 900+ any other custom tests for the language
To save time when running the tests, only 100, 430, 800+, 900+ should launch the handle.
FORMATTING CODE
Our C source code generally adheres to some basic code-formatting conventions. The
existing code base is not totally consistent on this front, but we do prefer that
contributed code be formatted similarly. In short, use spaces-not-TABs for indentation,
use 2 spaces for each indentation level, and other than that, follow the K&R style.
If you use Emacs, add the following to one of one of your start-up files (e.g., ~/.emacs),
to help ensure that you get indentation right:
;;; In libguestfs, indent with spaces everywhere (not TABs).
;;; Exceptions: Makefile and ChangeLog modes.
(add-hook 'find-file-hook
'(lambda () (if (and buffer-file-name
(string-match "/libguestfs\\>"
(buffer-file-name))
(not (string-equal mode-name "Change Log"))
(not (string-equal mode-name "Makefile")))
(setq indent-tabs-mode nil))))
;;; When editing C sources in libguestfs, use this style.
(defun libguestfs-c-mode ()
"C mode with adjusted defaults for use with libguestfs."
(interactive)
(c-set-style "K&R")
(setq c-indent-level 2)
(setq c-basic-offset 2))
(add-hook 'c-mode-hook
'(lambda () (if (string-match "/libguestfs\\>"
(buffer-file-name))
(libguestfs-c-mode))))
変更のテスト方法
Turn warnings into errors when developing to make warnings hard to ignore:
./configure --enable-werror
有用なターゲットは次のとおりです:
"make check"
一般的なテスト群を実行します。
This is implemented using the regular automake "TESTS" target. See the automake
documentation for details.
"make check-valgrind"
valgrind にあるテスト群のサブセットを実行します。
See "VALGRIND" below.
"make check-valgrind-local-guests"
ローカルにインストールされた libvirt 仮想マシン (読み込み専用) を使用して、valgrind に
あるテスト群のサブセットを実行します。
"make check-direct"
Runs all tests using default appliance back-end. This only has any effect if a non-
default backend was selected using "./configure --with-default-backend=..."
"make check-valgrind-direct"
Run a subset of the test suite under valgrind using the default appliance back-end.
"make check-uml"
Runs all tests using the User-Mode Linux backend.
As there is no standard location for the User-Mode Linux kernel, you have to set
"LIBGUESTFS_HV" to point to the kernel image, eg:
make check-uml LIBGUESTFS_HV=~/d/linux-um/vmlinux
"make check-valgrind-uml"
Runs all tests using the User-Mode Linux backend, under valgrind.
As above, you have to set "LIBGUESTFS_HV" to point to the kernel.
"make check-with-upstream-qemu"
Runs all tests using a local qemu binary. It looks for the qemu binary in QEMUDIR
(defaults to $HOME/d/qemu), but you can set this to another directory on the command
line, eg:
make check-with-upstream-qemu QEMUDIR=/usr/src/qemu
"make check-with-upstream-libvirt"
Runs all tests using a local libvirt. This only has any effect if the libvirt backend
was selected using "./configure --with-default-backend=libvirt"
It looks for libvirt in LIBVIRTDIR (defaults to $HOME/d/libvirt), but you can set this
to another directory on the command line, eg:
make check-with-upstream-libvirt LIBVIRTDIR=/usr/src/libvirt
"make check-slow"
Runs some slow/long-running tests which are not run by default.
To mark a test as slow/long-running:
• Add it to the list of "TESTS" in the Makefile.am, just like a normal test.
• Modify the test so it checks if the "SLOW=1" environment variable is set, and if
not set it skips (ie. returns with exit code 77). If using $TEST_FUNCTIONS, you
can call the function "slow_test" for this.
• Add a variable "SLOW_TESTS" to the Makefile.am listing the slow tests.
• Add a rule to the Makefile.am:
check-slow:
$(MAKE) check TESTS="$(SLOW_TESTS)" SLOW=1
"sudo make check-root"
Runs some tests which require root privileges. These are supposed to be safe, but
take care. You have to run this as root (eg. using sudo(8) explicitly).
To mark a test as requiring root:
• Add it to the list of "TESTS" in the Makefile.am, just like a normal test.
• Modify the test so it checks if euid == 0, and if not set it skips (ie. returns
with exit code 77). If using $TEST_FUNCTIONS, you can call the function
"root_test" for this.
• Add a variable "ROOT_TESTS" to the Makefile.am listing the root tests.
• Add a rule to the Makefile.am:
check-root:
$(MAKE) check TESTS="$(ROOT_TESTS)"
"make check-all"
Equivalent to running all "make check*" rules except "check-root".
"make check-release"
Runs a subset of "make check*" rules that are required to pass before a tarball can be
released. Currently this is:
• check
• check-valgrind
• check-direct
• check-valgrind-direct
• check-slow
"make installcheck"
Run "make check" on the installed copy of libguestfs.
The version of installed libguestfs being tested, and the version of the libguestfs
source tree must be the same.
Do:
./autogen.sh
make clean ||:
make
make installcheck
VALGRIND
When you do "make check-valgrind", it searches for any Makefile.am in the tree that has a
"check-valgrind:" target and runs it.
Writing the Makefile.am and tests correctly to use valgrind and working with automake
parallel tests is subtle.
If your tests are run via a shell script wrapper, then in the wrapper use:
$VG virt-foo
and in the Makefile.am use:
check-valgrind:
make VG="@VG@" check
However, if your binaries run directly from the "TESTS" rule, you have to modify the
Makefile.am like this:
LOG_COMPILER = $(VG)
check-valgrind:
make VG="@VG@" check
In either case, check that the right program is being tested by examining the
tmp/valgrind* log files carefully.

DAEMON CUSTOM PRINTF FORMATTERS
In the daemon code we have created custom printf formatters %Q and %R, which are used to
do shell quoting.
%Q シンプルなシェルクオート文字列。すべての空白と他のシェル文字がエスケープされます。
%R Same as %Q except the string is treated as a path which is prefixed by the sysroot.
例:
asprintf (&cmd, "cat %R", path);
"cat /sysroot/some\ path\ with\ spaces" を生成します
Note: Do not use these when you are passing parameters to the "command{,r,v,rv}()"
functions. These parameters do NOT need to be quoted because they are not passed via the
shell (instead, straight to exec). You probably want to use the "sysroot_path()" function
however.
国際化 (i18n) サポート
We support i18n (gettext anyhow) in the library.
However many messages come from the daemon, and we don't translate those at the moment.
One reason is that the appliance generally has all locale files removed from it, because
they take up a lot of space. So we'd have to readd some of those, as well as copying our
PO files into the appliance.
Debugging messages are never translated, since they are intended for the programmers.
MISCELLANEOUS TOPICS
HOW OCAML PROGRAMS ARE COMPILED AND LINKED
Mostly this section is "how we make automake & ocamlopt work together" since OCaml
programs themselves are easy to compile.
Automake has no native support for OCaml programs, ocamlc nor ocamlopt. What we do
instead is to treat OCaml programs as C programs which happen to contain these "other
objects" ("DEPENDENCIES" in automake-speak) that happen to be the OCaml objects. This
works because OCaml programs usually have C files for native bindings etc.
So a typical program is described as just its C sources:
virt_v2v_SOURCES = ... utils-c.c xml-c.c
For programs that have no explicit C sources, we create an empty dummy.c file, and list
that instead:
virt_resize_SOURCES = dummy.c
The OCaml objects which contain most of the code are listed as automake dependencies
(other dependencies may also be listed):
virt_v2v_DEPENDENCIES = ... cmdline.cmx v2v.cmx
The only other special thing we need to do is to provide a custom link command. This is
needed because automake won't assemble the ocamlopt command, the list of objects and the
"-cclib" libraries in the correct order otherwise.
virt_v2v_LINK = \
$(top_srcdir)/ocaml-link.sh -cclib '-lutils -lgnu' -- ...
The actual rules, which you can examine in v2v/Makefile.am, are a little bit more
complicated than this because they have to handle:
• Compiling for byte code or native code.
• The pattern rules needed to compile the OCaml sources to objects.
These are now kept in subdir-rules.mk at the top level, which is included in every
subdirectory Makefile.am.
• Adding OCaml sources files to "EXTRA_DIST".
Automake isn't aware of the complete list of sources for a binary, so it will not add
them all automatically.
VIRT-V2V
First a little history. Virt-v2v has been through at least two complete rewrites, so this
is probably about the third version (but we don't intend to rewrite it again). The
previous version was written in Perl and can be found here:
https://git.fedorahosted.org/git/virt-v2v.git
The current version started out as almost a line-for-line rewrite of the Perl code in
OCaml + C, and it still has a fairly similar structure. Therefore if there are details of
this code that you don't understand (especially in the details of guest conversion),
checking the Perl code may help.
The files to start with when reading this code are:
• types.mli
• v2v.ml
types.mli defines all the structures used and passed around when communicating between
different bits of the program. v2v.ml controls how the program runs in stages.
After studying those files, you may want to branch out into the input modules (input_*),
the output modules (output_*) or the conversion modules (convert_*). The input and output
modules define -i and -o options (see the manual). The conversion modules define what
guest types we can handle and the detailed steps involved in converting them.
Every other file in this directory is a support module / library of some sort. Some code
is written in C, especially where we want to use an external C library such as libxml2.
VIRT-P2V
Virt-p2v is a front end on virt-v2v. ie. All it does is act as a GUI front end, and it
calls out to virt-v2v to perform the actual conversion. Therefore most of the C code in
the p2v/ subdirectory is Gtk (GUI) code, or supporting code for talking to the remote
conversion server. There is no special support for physical machines in virt-v2v. They
are converted in the same way as foreign VMs.
Running virt-p2v
You can run the p2v/virt-p2v binary directly, but it will try to convert your machine's
real /dev/sda which is unlikely to work well. However virt-p2v also has a test mode in
which you can supply a test disk:
make -C p2v run-virt-p2v-directly
This is a wrapper around the virt-p2v(1) --test-disk option. You can control the
"physical machine" disk by setting "PHYSICAL_MACHINE" to point to a disk image.
A more realistic test is to run virt-p2v inside a VM on the local machine. To do that,
do:
make -C p2v run-virt-p2v-in-a-vm
This also runs qemu with the "physical machine" disk (which you can set by setting
"PHYSICAL_MACHINE"), a virtual CD, and a variety of network cards for testing. You can
change the qemu binary and add extra qemu options by setting "QEMU" and/or "QEMU_OPTIONS"
on the make commandline.
A third way to run virt-p2v simulates fairly accurately the program being downloaded over
PXE and then doing an automatic conversion of the source physical machine (the non-GUI
path -- see next section below):
make -C p2v run-virt-p2v-non-gui-conversion
Understanding the virt-p2v code
See also: "HOW VIRT-P2V WORKS" in virt-p2v(1)
There are two paths through the code, GUI or non-GUI (parsing the kernel command line):
main.c ──────┬─────▶ gui.c ──────┬─────▶ conversion.c
│ │
│ │
└────▶ kernel.c ────┘
but both paths call back to the conversion.c function "start_conversion" to run the remote
virt-v2v.
The main task of gui.c/kernel.c is to populate the virt-v2v configuration (config.c).
During conversion, we need to establish ssh connections, and that is done using two
libraries:
conversion.c ──────▶ ssh.c ──────▶ miniexpect.c
where ssh.c is responsible for managing ssh connections overall, and miniexpect.c
implements "expect-like" functionality for talking interactively to the remote virt-v2v
conversion server.
(Note that miniexpect is a separate library with its own upstream, so if you patch
miniexpect.c, then please make sure the changes get reflected in miniexpect's upstream
too: http://git.annexia.org/?p=miniexpect.git;a=summary)
MAINTAINER TASKS
MAINTAINER MAKEFILE TARGETS
These "make" targets probably won't work and aren't useful unless you are a libguestfs
maintainer.
make maintainer-commit
This commits everything in the working directory with the commit message "Version
$(VERSION).". You must update configure.ac, clean and rebuild first.
make maintainer-tag
This tags the current HEAD commit with the tag "v$(VERSION)" and one of the messages:
Version $(VERSION) stable
Version $(VERSION) development
(See "LIBGUESTFS VERSION NUMBERS" in guestfs(3) for the difference between a stable and
development release.)
make maintainer-check-extra-dist
This rule must be run after "make dist" (so there is a tarball in the working directory).
It compares the contents of the tarball with the contents of git to ensure that no files
have been missed from Makefile.am "EXTRA_DIST" rules.
make maintainer-upload-website
This is used by the software used to automate libguestfs releases to copy the libguestfs
website to another git repository before it is uploaded to the web server.
MAKING A STABLE RELEASE
When we make a stable release, there are several steps documented here. See "LIBGUESTFS
VERSION NUMBERS" in guestfs(3) for general information about the stable branch policy.
• Check "make && make check" works on at least:
Fedora (x86-64)
Debian (x86-64)
Ubuntu (x86-64)
Fedora (aarch64)
Fedora (ppc64)
Fedora (ppc64le)
• Check "./configure --without-libvirt" works.
• Finalize guestfs-release-notes.pod
• Push and pull from Zanata.
次を実行します:
zanata push
to push the latest POT files to Zanata. Then run:
./zanata-pull.sh
which is a wrapper to pull the latest translated *.po files.
• Consider updating gnulib to latest upstream version.
• http://libguestfs.org/download の下に新しい安定版および開発版のディレクトリーを作成し
ます。
• Edit website/index.html.in.
• Set the version (in configure.ac) to the new stable version, ie. 1.XX.0, and commit
it:
./localconfigure
make distclean -k
./localconfigure
make && make dist
make maintainer-commit
make maintainer-tag
• Create the stable branch in git:
git branch stable-1.XX
git push origin stable-1.XX
• Do a full release of the stable branch.
• Set the version to the next development version and commit that. Optionally do a full
release of the development branch.
