Just code motion.
This commit makes it clearer what is a utility and what is part of the
library. It also makes it clear that we should rename:
guestfs-internal-frontend.h -> utils.h
guestfs-internal-frontend-cleanups.h -> cleanups.h (?)
but this commit does not make that change.
When TESTS_ENVIRONMENT already uses 'run', the VG variable
doesn't also need to use 'run'.
The specific problem is that if the command contains newlines
then double invocations of the 'run' script fails (in libtool).
ie the following command failed causing errors in check-valgrind:
$VG virt-builder phony-fedora \
-v --no-cache --no-check-signature $no_network \
...
--write '/etc/append4:line1
' \
...
Create a new libfishcommon convenience static library to build just once
(instead of 12 times!) the majority of the guestfish sources used in the
rest of the C tools (mostly for command line stuff, inspection, and
mount).
The notable exceptions not using libfishcommon are guestfish itself, and
virt-rescue: both need to build at least one of the common sources using
additional CPPFLAGS.
Some of the C tools were building also config.c as part of the shared
sources from guestfish, and thus bringing a dependency on libconfig.
Since none of them actually read the libguestfs configuration at all,
then exclude fish/config.c from their build, and stop linking to
libconfig.
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.
By moving these two functions out of the common options parsing code,
it means we don't need to depend on all the other machinery of options
parsing, such as the global variables ("verbose"), libconfig, etc.
podcheck.pl is run as part of the tests to perform various checks on
the documentation and the tool.
Currently we check only that the documented options matches the
options that the tool implements and vice versa. This commit would
also allow us (in future) to check --help, --long-options,
--short-options, --version output.
This commit includes scripts to run the tests and various fixes to the
manual pages to ensure that the tests pass.
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?)
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.
Add a remote drive by doing:
guestfish -a ssh://example.com/path/to/disk.img
There are several different protocols supported, as explained in the
man page.
This affects all virt-* tools that use the common guestfish options
parsing code.
The libutils convenience library is a place for code shared between
the main library, language bindings and virt tools. Note that the
code is statically linked into both the library, each binding and each
tool, but this is an improvement because (a) the source is shared and
(b) libguestfs.so can export fewer private functions.
Currently it contains the cleanup functions, and the functions
guestfs___free_string_list function and guestfs___for_each_disk.
guestfs___for_each_disk has changed so that it no longer
unconditionally sets the error in the guestfs handle. Instead callers
can control error handling.
Certain functions are intended to be internal only, but we currently
export them anyway. This change moves them into a separate section of
guestfs.h protected by a GUESTFS_PRIVATE variable. This change also
enables private structs, but doesn't implement any.
This change only affects the C api. Language bindings aren't affected,
but probably should be in the future.
Rename guestfs_safe_malloc et al to guestfs___safe_malloc etc.
To use the private functions, code now has to define
-DGUESTFS_PRIVATE_FUNCTIONS=1. This will make it easier for us in
future to work out which programs are using these functions and to
minimize both the number of programs and the functions they are
calling.
Note that the Perl, Python, OCaml, Ruby and Java bindings use
guestfs_safe_* calls. None of the other bindings do. This is a bug
(in the bindings using those functions): these functions will call the
out of memory callback on failure. This function defaults to abort(),
and since this happens from a language binding, there is no way to
change this default.
These configure flags enable code profiling (with gprof) and code
coverage (with gcov) respectively.
Although this is a nice idea, it's not currently very useful.
Libtool mangles filenames in such a way that gcov cannot locate its
datafiles.
Profiling is of dubious utility with libguestfs which is not CPU-bound
and relies extensively on running external programs (oprofile-like
system profiling that took into account libguestfs + qemu or
libguestfs + qemu + the appliance + filesystem tools *would* be
useful).
Also neither flag will help in capturing data from the appliance.
'make extra-tests' was a monolithic set of tests that did all sorts of
things: valgrind, tests over local guests, tests with upstream qemu,
tests with upstream libvirt, tests with the appliance attach method.
This made it hard to perform individual tests, eg. just valgrind
testing. It was also hard to maintain because the tests were not
located in the same directories as the programs and sometimes
duplicated tests that were run elsewhere.
This commit splits up 'make extra-tests' into 5 separate targets:
make check-valgrind # run a subset of tests under valgrind
make check-valgrind-local-guests # test under valgrind with local guests
make check-with-appliance # test with attach-method == appliance
make check-with-upstream-qemu # test with an alternate/upstream qemu
make check-with-upstream-libvirt # test with an alternate/upstream libvirt
(You can also still run 'make extra-tests' which is now simply
a rule that runs the above 5 targets in order).
This replaces everything that was in the tests/extra directory,
so that has now gone.
This adds standard LICENSE and BUGS sections to all of the man pages
that are processed by podwrapper.
Modify all the calls to $(PODWRAPPER) to add the right --license
parameter according to the content. Note that this relaxes the
license on some code example pages, making them effectively BSD-style
licensed.
MALLOC_PERTURB_ is a glibc feature which causes malloc to wipe memory
before and after it is used, allowing both use-after-free and
uninitialized reads to be detected with relatively little performance
penalty:

Modify the ./run script so that it always sets this.
We were already using MALLOC_PERTURB_ in most tests. Since ./run is
now setting this, we can remove it from individual Makefiles. Most
TESTS_ENVIRONMENT will now simply look like this:
TESTS_ENVIRONMENT = $(top_builddir)/run --test
This option, when added via
TESTS_ENVIRONMENT = [...] $(top_builddir)/run --test
allows us to run the tests and only print the full output (including
debugging etc) when the test fails.
The output looks like this:
F16x64:/dev/sda1 1048576 1024K ok
F16x64:/dev/sda2 2097152 2048K ok
F16x64:/dev/sda3 526385152 2048K ok
If the --uuid option is used, then UUIDs are shown instead of names.
