This option (alternately spelled: --color, --colour, --colors, or
--colours) enables ANSI colour sequences output even if that would be
disabled becaues the output is not a TTY.
OCaml 4.02 introduced the 'bytes' type, a mutable string intended to
replace the existing 'string' type for those cases where the byte
array can be mutated. In future the 'string' type will become
immutable. This is not the default now, but it can be forced using
the '-safe-string' compile option.
This commit changes the code so that it could be compiled using
'-safe-string' (but does not actually make that change).
If we detect OCaml < 4.02, we create a dummy 'Bytes' compatibility
module ((nearly) an alias for the 'String' module). The only
significant difference from upstream OCaml is that you must write the
'bytes' type as 'Bytes.t' in interfaces, apart from that everything
else should work.
In commit ae6f726ecc we started to use
the virt-customize code to replace various virt-sysprep operations.
This had the effect of adding many more possible operations to
virt-sysprep, but some of them (specifically --install) did not work
unless the appliance network is enabled. It was not enabled in
virt-sysprep, so these operations never worked.
This change does NOT enable the network by default. However it adds a
--network flag which may be used in conjunction with --install etc to
make those commands work.
In addition we now emit a warning for certain customize operations if
they fail and if the network is not enabled. It will print:
[ 4.5] Installing packages: tcpdump
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was
virt-sysprep: warning: the command may have failed because the network is
disabled. Try either removing '--no-network' or adding '--network' on the
command line.
virt-sysprep: error: yum -y install 'tcpdump': command exited with an error
(If the network is already enabled, or if the command is successful,
then the warning is not printed.)

Returns true if the device is a host partition.
The only tedious bit of this patch is that now Common_utils depends on
Dev_t so we have to add extra objects every time something links with
Common_utils.
Sync the windows firstboot script with its linux brother. Also change
the main redirection to append to the log rather than overwriting it.
With this change, the firstboot script will resist reboots in the
executed scripts.
Add a common debug function for printing debugging messages. It only
emits the debug message when the verbose (-v) flag is used on the
command line.
It sends the output to stderr, which is flushed immediately after the
message is printed (to help with debugging unexpected crashes). There
are good arguments for sending the debug to either stdout or stderr,
and almost all existing debug messages replaced by this change went to
stdout. However using stderr is consistent with libguestfs's own
debug messages which also go to stderr.
I only made simple changes to code of the form 'if verbose () then
printf ...'. There are more places which could be changed in future.
In a few places I removed gettext calls since we probably should not
translate debug messages.
It is still only emitted if we are debugging in order not to cause
unnecessary alarm. Note this code needs a better long term fix, this
is still a hack.
Only in very recent OCaml versions (or in Fedora) the Arg module
supports the --foo=bar syntax for options with arguments. Do not
require it yet.
Fixes commit 64bb9edd52.
When possible, make the disk image format explicit when invoking tools
or using add-drive. This avoids warnings from qemu about the unspecified
format for the image, and also makes qemu slightly faster (skipping the
disk image probing).
Tests checking the image probing are not touched.
This changes also:
- old-style invocations of tools (`$tool $filename`) into new style
(`$tool -a $filename`)
- add-drive-ro/add-drive-with-if guestfish commands into add/add-drive
with explicit readonly/iface arguments
There should be no change in the tests results.
Turn the snippet reading user information from /etc/passwd in a slightly
more generic function, so there is no need to copy&paste for other
details.
Mostly code motion.
For Windows, we now print:
$ virt-customize -a ./test-data/phony-guests/windows.img --install MSSQL
[ 0.0] Examining the guest ...
[ 14.2] Setting a random seed
virt-customize: warning: random seed could not be set for this type of
guest
[ 14.2] Installing packages: MSSQL
virt-customize: error: cannot use '--install' because no package manager
has been detected for this guest OS.
If this guest OS is a common one with ordinary package management then this
may have been caused by a failure of libguestfs inspection.
For OSes such as Windows that lack package management, this is not
possible. Try using one of the '--firstboot*' flags instead (described in
the manual).
Introduce and use a new inspect_mount_root function to mount all the
mountpoints of a root in the guest, replacing the same code doing that
in different tools.
inspect_mount_root_ro is inspect_mount_root with readonly mount option.
Support globbing in paths passed to --delete, telling glob to not
return directories with leading slash.
This re-adds back globbing for --delete in virt-sysprep, which was
available before the integration with common code from virt-customize.
For functions linked to virt tools, make sure the name of the function
actually matches the virt tool. Because of the history of moving
functions across tools, some names no longer matched.
For mllib, use `guestfs_int_mllib_' prefix.
For OCaml bindings, use `guestfs_int_ocaml_' prefix.
This commit is by no means complete. There are many other C functions
in other language bindings which could do with being more consistently
named.
There is no functional change, this is just refactoring.
Actually the OCaml compiler rewrites all printf functions at compile
time to a series of primitive string operations, so the use of sprintf
here doesn't really matter. Still, it's a bit tidier not to use
sprintf where it's not needed.
Also this commit contains some code reformatting.
This is just refactoring.
Instead of creating Guestfs handles and manually apply common options
(e.g. debug and trace), use the open_guestfs in Common_utils.
This also applies the common options to handles which didn't set them
before, so we can inspect also their messages if needed.
Resolve also symlinks when checking whether a path passed to --edit is a
file: the file editing code supports symlinks anyway (properly changes
the target file, instead of overwrite the symlink with a real file), so
it is safe to allow this operation in customize/builder.
Check that a path provided to --edit exists already; while the is_file
call later will fail for non-existing files, with an explicit check a
better error message can be provided.
Move the random set of HTML files we build from html/ into
the website/ directory.
Also in the website/ directory, put the index.html file from
http://libguestfs.org, which was previously not under version control.
It is generated from index.html.in so we can automatically add the
current version and release date.
Also in the website/ directory, put various CSS file, images, etc.
which are required by the website and were also previously not under
version control.
Change the 'make website' rule to 'make maintainer-upload-website'.
As the name suggests, it is only useful for the maintainer, and will
fail with an error for anyone else.
Create a new top-level directory called test-data, which will carry
all the test data which is large and/or shared between multiple tests.
There are actually several new subdirectories created:
test-data/binaries: The pre-built binary and library files for random
architectures that we use to test various architecture detection
features (was part of tests/data).
test-data/blank-disks: The blank disks which are used for disk format
detection (was part of tests/data).
test-data/files: Other miscellaneous test files from tests/data that
are not included in the above.
test-data/phony-guests: The phony guests (was tests/guests).
test-data: The top-level directory builds the 'test.iso' image file
that is used for testing the C API and in miscellaneous other tests.
Unfortunately Coccinelle places a Config module in the ocaml libdir,
and this confuses ocamlfind (only when Coccinelle is installed).
Since this is a private module that only libguestfs tools use
internally, just rename it from Config -> Guestfs_config.
This is just a straight refactoring. Various ad hoc string_*
functions that appeared in Common_utils have been renamed and placed
in the String.* namespace. The old vs "new" functions are:
string_prefix -> String.is_prefix
string_suffix -> String.is_suffix
string_find -> String.find
replace_str -> String.replace
string_nsplit -> String.nsplit
string_split -> String.split
string_lines_split -> String.lines_split
string_random8 -> String.random8
Use the generator_built variable to list any files which are built by
the generator. This ensures they get automatically rebuilt.
Three files were missing from EXTRA_DIST, so they were not included in
the tarball, meaning you would have needed OCaml to build from the
tarball. You would have seen this when building:
cd .. && /builddir/build/BUILD/libguestfs-1.31.9/generator/generator
written gobject/docs/guestfs-title.sgml
written customize/customize-synopsis.pod
written customize/customize-options.pod
generated 476921 lines of code
Move --debug-gc as common option for all the OCaml-based tools, even a
couple of them which didn't have it previously.
As implementation note, make set_debug_gc private to
set_standard_options, as it needed to be moved otherwise, and it is no
more required as public function.
