This patch also changes the way that the version is specified
in configure.ac. It is now made out of four parts (major, minor,
release and extra) and constructed for AC_INIT.

Calls such as stat and statvfs which returned a single structure
were returning an array of values instead of a full hash of keys +
values.
Fix this by pushing the key names on the stack too.

This adds an extra Perl module called Sys::Guestfs::Lib which
adds useful functions for using libguestfs from Perl.
The intention is that common code shared between virt-inspector,
virt-df and virt-v2v will move into this library.
This patch also changes virt-inspector to use this library.

Originally it was looking for 'config.status', but this file
might not exist until configure has been run. Make it look for
HACKING instead.

This modifies the way that struct and struct lists are generated
(for return values) so that there is no need to add an explicit
new type when adding a new structure.
All tests pass, and the C API should be compatible.
I have also inspected the changes that are made to the generated
code by hand.

This is used to get the PID of the qemu subprocess, mainly for
debugging and testing purposes.

This patch allows you to do:
mkdir build
cd build
../configure ...
make
This will output all generated files to the build directory. Given that
autogen automatically runs configure, you can also do:
BUILDDIR=./build ./autogen.sh
which will do the right thing.
Also:
* Fix a dependency bug which means that guestfs_protocol.h
isn't automatically rebuilt.
* Re-running autogen.sh with no arguments won't blow away your previous
configure arguments.

* src/generator.ml: Add a few "const" attributes.
|
| |
|
|
|
|
|
|
|
|
| |
* src/generator.ml (safe_malloc): Define to guestfs_safe_malloc.
(safe_calloc): Define to guestfs_safe_calloc.
[most generated code]: Fail immediately upon failure of otherwise-
unchecked malloc and calloc calls.
* src/guestfs.c: Include <stddef.h>.
(xalloc_oversized): Define.
* src/guestfs.h (guestfs_safe_calloc): Declare.
|
| |
|
|
|
| |
* src/generator.ml: Slightly safer, in case the
declared type ever changes.

This command is a saner interface to partitioning.
All partition sizes are specified in megabytes (not cylinders).
You don't need to specify the cyls/heads/secs parameters.
All the test code has been updated to use this, so it is now
CHS-independent (eg. when CHS changes as between IDE and virtio).

With this flag the packager can decide to default to a particular
qemu drive model. The current default is 'ide', however note that
we intend to change this in future to 'virtio' once some upstream
regressions are fixed. Packagers can force a particular drive
model if they wish.

Messages which include the proc_nr can now also include the
name of the actual function being called.

This speeds up the generator greatly.

This adds a readdir call (mostly intended for programs). The
return value is a list of guestfs_dirent structures.
This adds the new types 'struct guestfs_dirent' and
'struct guestfs_dirent_list', along with all the code to
return these in the different language bindings.
Also includes additional tests for OCaml and Perl bindings
to test this.

virtio_blk is the fast, virt-native block device driver
supported by qemu and KVM. Note that virtio_blk device
names are called /dev/vd*.
Existing scripts should continue working because device name
translation will silently change device names of the form
/dev/sd* to /dev/vd* as required.

Current statvfs test depended on a lot of filesystem details
which can change if the CHS of the underlying block device
changes (eg. with the switch from IDE -> virtio). These are
not really necessary to test the call, so instead just check
for filesystem features.

Set output mode to unbuffered so that we see ordinary output
messages and errors at the same time.
Align "skipped" messages.

These commands are used to create block and char device
nodes or FIFOs (named pipes) in the filesystem.
The umask command is required also because the permissions
used by mknod are masked by the umask.
Also document and guarantee that the umask starts as 022.

We have to use the OCaml convention (0o...). Note that in
OCaml 0777 is a _decimal_ number. It'll catch you out.

Allow the qemu memory size to be specified either by API
calls or by setting the LIBGUESTFS_MEMSIZE environment
variable.

These commands are used to make Linux swap devices. The mkswap_L
command makes one with a label. The mkswap_U command makes one
with a known UUID.

Loop device mounts don't work for the generic 'mount' commands
because the first parameter should be a file not a device.
We want to separate out files parameters from device parameters
in the long term, so this adds a new mount-loop command for this
purpose.

Add 'initrd-list' command to list the files inside (new-style)
initrd images. Update virt-inspector to use this instead of
the less efficient download/unpack locally method.
|

|
|

This command estimates file usage for files and directories.
|
| |
|
|
|
|
|

df and df-h commands can be used interactively to show disk
space usage.
Use existing statvfs command from programs.

These commands let you view parts of a large file without
passing the whole file over the network connection.
|

|
|
|

Parameters named 'n' sometimes break the Perl bindings, so
check for this in the generator and prevent it.

These commands count characters, words and lines in a file respectively.

To run just selected tests, do:
TEST_ONLY="hexdump mkfs" make -C capitests check
|
| |
|
|
|

Large test files with standard content for the C API test, and
add a regression test for previous hexdump failure on large files.

Use maximum proc_nr (MAX_PROC_NR) as a surrogate for the
library ABI version, resulting in version numbers such as
libguestfs.so.0.<MAX_PROC_NR>.0 for the final library.
Add ABI guarantee to the documentation.
