Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
Isolate the logic for the memoized disk cache in a small module, so it
can be reused for other tools.
Other than refactoring, there should be no behaviour changes.
After this commit, all annocheck errors are fixed except for:
Hardened: virt-get-kernel: MAYB: Gaps were detected in the annobin coverage. Run with -v to list.
After discussion with the annocheck maintainers this gap in coverage
(which corresponds to the OCaml runtime) seems to be caused either by
the runtime not being linked with the right flags, or might be a bug
in annocheck itself. In any case it's not something that can be
resolved within the scope of libguestfs.
Mostly refactoring to make it easier to add fields to this struct in
future.
I'd like to call the header p2v/config.h but that's not possible since
it conflicts with the autoconf-generated file.
hivex has a function hivex_value_string. We were not calling it under
the mistaken belief that because hivex implements this using iconv,
the function wouldn't work inside the daemon. Instead we
reimplemented the functionality in the library.
This commit deprecates hivex_value_utf8 and removes the library side
code. It replaces it with a plain wrapper around hivex_value_string.

These are generated in many different ways in the various
subdirectories, and sometimes not generated correctly. Introduce a
script to do this in one place, and hopefully correctly.
This is mostly simple refactoring, but I got rid of a couple of
things:
(1) The ‘make depend’ rule doesn't appear to be needed. automake (or
make?) seems to rebuild the ‘.depend’ file automatically just because
it is included.
(2) I got rid of the hairy path rewriting sed expression. Possibly
that is needed for srcdir != builddir.
Even if ocamlopt is available, always build a bytecode version of
‘common/mlstdutils’.
Furthermore, because this library is pure OCaml, we should not be
using ‘ocamlmklib’. We should use ‘ocaml{c,opt} -a’ instead. This
doesn't make any difference for native code, but for bytecode it was
building a broken library.
The original reason for making this change is because the generator is
always built as bytecode, and it depended on
‘../common/mlstdutils/guestfs_config.cmo’ and
‘../common/mlstdutils/std_utils.cmo’. On native code platforms these
were not built before the generator and so the generator races to
build the .cmi and .cmo files. Since the generator doesn't have
correct dependencies covering the ‘common/mlstdutils’ directory you
can get a broken link on fast machines:
File "../common/mlstdutils/std_utils.ml", line 1:
Error: Corrupted compiled interface
../common/mlstdutils/guestfs_config.cmi
make[2]: *** [Makefile:1993: ../common/mlstdutils/std_utils.cmo] Error 2
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory '/builddir/build/BUILD/libguestfs-1.37.17/generator'
Previously the OCaml compiler was only required if building from git
but was at least theoretically optional if building from tarballs
(although this was never tested). Since we want to write parts of the
daemon in OCaml, this makes OCaml required for all builds.
Note that the ‘--disable-ocaml’ option remains, but it now only
disables OCaml bindings and OCaml virt tools. Using this option does
not disable the OCaml compiler requirement.
Also note that ‘HAVE_OCAML’ changes meaning slightly, so it now means
"build OCaml bindings and tools" (analogous to ‘HAVE_PERL’ and
others). The generator, daemon [in a future commit], and some utility
libraries needed by the generator or daemon do not test for this macro
because we can assume OCaml compiler availability.
Place the Bytes fallback module in the right place (mlstdutils), with no
need to make it available directly also for generation, since it uses
mlstdutils now.
Fixes commit 61d4891ef4.
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.
The yara_load API allows to load a set of Yara rules contained within a
file on the host.
Rules can be in binary format, as when compiled with yarac command, or
in source code format. In the latter case, the rules will be first
compiled and then loaded.
Subsequent calls of the yara_load API will result in the discard of the
previously loaded rules.

Daemon 'proc_nr's have to be assigned monotonically and uniquely to
each daemon function. However in practice it can be difficult to work
out which is the next free proc_nr. Placing all of them into a single
table in a new file (proc_nr.ml) should make this easier.
Group the APIs logically and move them into new modules:
Actions_core:
Core APIs and anything that doesn't fit into another group, eg. launch.
(With some more effort this could be split further.)
Actions_augeas:
Augeas APIs, eg. aug-init.
Actions_debug:
Debug APIs.
Actions_hivex:
Hivex APIs, eg. hivex-open.
Actions_inspection:
Inspection APIs, eg. inspect-get-type.
Actions_properties:
Handle properties, eg. set-hv, get-hv.
Actions_tsk:
SleuthKit APIs, eg. filesystem-walk.
*_deprecated:
All of the above modules have deprecated variants, where we
place the deprecated actions.
- Make module name explicit, so it's more obvious which module a
function is defined in.
- Group lines of code by feature.
- Capitalize some module names properly.
Just code motion, no functional change.
Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
For a very long time we have maintained two sets of utility functions,
in mllib/common_utils.ml and generator/utils.ml. This changes things
so that the same set of utility functions can be shared with both
directories.
It's not possible to use common_utils.ml directly in the generator
because it provides several functions that use modules outside the
OCaml stdlib. Therefore we add some lightweight post-processing which
extracts the functions using only the stdlib:
(*<stdlib>*)
...
(*</stdlib>*)
and creates generator/common_utils.ml and generator/common_utils.mli
from that. The effect is we only need to write utility functions
once.
As with other tools, we still have generator-specific utility
functions in generator/utils.ml.
Also in this change:
- Use String.uppercase_ascii and String.lowercase_ascii in place
of deprecated String.uppercase/String.lowercase.
- Implement String.capitalize_ascii to replace deprecated
String.capitalize.
- Move isspace, isdigit, isxdigit functions to Char module.
By adding common CLEANFILES and DISTCLEANFILES variables to
common-rules.mk, we can remove these from most other Makefiles, and
also clean files more consistently.
Note that bin_PROGRAMS are already cleaned by 'make clean', so I
removed cases where these were unnecessarily added to CLEANFILES.
Previously we had a list of UEFI paths in src/uefi.c, which was
accessed in virt-v2v using a private (guestfs_int_*) API and some C
binding code. This was clumsy and required the paths to be replicated
in the virt-v2v unit tests.
Instead just generate the list of paths from the generator, creating
src/uefi.c and v2v/uefi.ml with the same content.
Remove the C bindings and the virt-v2v unit tests associated with UEFI
paths.
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.
Remove man pages and other pages which 'make clean' did not remove
before.
To evaluate which pages could be removed, I did a full build and
check, and then ran 'make clean' followed by 'git clean -xdf'. By
examining the output of the git clean command I could see which files
were being missed.
Files that are _not_ removed by make clean or make distclean:
- generator-built files
- Makefile, Makefile.in, .deps, .depend
- any ./configure output files (maybe they should be?)
ocamldep -all (introduced in commit a3881445ef) creates a dependency
rule
optgroups.cmi ... : utils.cmx ...
Because we never build a native code version of the generator,
utils.cmx can never be remade, and so this results in optgroups.cmi
being always rebuilt and hence rebuilding the whole directory.
It's unclear how to fix this, but reverting the ocamldep -all change
in this directory works around it.
Partially reverts commit a3881445ef.
In v2v, 'stringMap.ml' has no corresponding *.mli file. ocamldep does
not generate a *.cmi dependency for such modules, and this can result
in parallel builds failing rarely because:
(1) stringMap.ml is built (which has the side-effect of generating
stringMap.cmi)
(2) at the same time, types.mli is compiled. types.mli depends on
stringMap.cmi, but it is half way through being created by (1).
There is no dependency to serialize (1) and (2).
The resulting error is:
File "types.mli", line 1:
Error: Corrupted compiled interface
stringMap.cmi
Using 'ocamldep -all' generates extra deps for the *.cmi files, and
otherwise appears to be safe, so use it.
There are currently a few upstream OCaml bugs with dependencies and
parallel builds:
http://caml.inria.fr/mantis/view.php?id=3190http://caml.inria.fr/mantis/view.php?id=4991http://caml.inria.fr/mantis/view.php?id=5000
It's not clear which of these apply here.
In OCaml 4.02, the 'string' type can be made immutable. All String.*
functions that are concerned with creating or mutating strings now
give a warning like this:
Warning 3: deprecated feature: String.unsafe_set
Disable this warning since we don't want to turn on immutable strings
yet.
Split virt-builder into build and customize steps, so that we can spin
off a separate tool called 'virt-customize'. This commit does not in
fact create such a tool, but it moves all the common code into a
library, in the customize/ subdirectory of the source.
Although this is mostly refactoring, it does change the order in which
virt-builder command line arguments are processed, so they are now
processed in the order they appear, not the inflexible fixed order
used before.
This file is mainly a central place to:
- include localenv if it exists, and
- define the RHEL 5 backwards compatibility macros, instead of
spreading them over every other file.
