The documentation for Module::Build is completely opaque on how you're
supposed to pass @CFLAGS@ correctly. However I noticed that we were
not passing -g through when generating Guestfs.so:
gcc -lpthread -shared -Wl,-z,relro -Wl,--as-needed -Wl,-z,pack-relative-relocs -Wl,-z,now '-specs=/usr/lib/rpm/redhat/redhat-hardened-ld' '-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1' '-Wl,--build-id=sha1' -L/usr/local/lib -fstack-protector-strong -lperl -o blib/arch/auto/Sys/Guestfs/Guestfs.so lib/Sys/Guestfs.o -L../lib/.libs -lguestfs
This debuginfo was not always being generated correctly. (For some
reason it still manages to be generated in Fedora and RHEL 9, but not
in RHEL 10, this part is still unclear to me.)
Anyway it seems we ought to pass at least -g to the linker, and we
might as well pass the full set of @CFLAGS@, hence this change.
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').
This brings libguestfs into line with other projects which have a
separate include/ directory for the public header.
It's also the case that <guestfs.h> has never particularly belonged in
the lib/ subdirectory. Some tools add -Ilib/ but they only need
<guestfs.h> and not any other headers from that directory, and
separating out the public header allows us to clean those up. This is
certainly the case for examples, and some language bindings and some
tests.
In future I'm hopeful we can use this as the basis to tease out other
dependencies, as a prelude to separating them out from the repo.
It is not something standard, and actually unused by libguestfs itself.
Possibly going to be used by the old virt-v2v (which was in Perl), but
never used for that either.
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.)
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.
Introduce a new kind of bindings tests, 090-retvalues, to check all the
possible return values in bindings; start implementing them for
scripting languages such as GObject introspection, Perl, PHP, Python,
and Ruby, reusing existing implementations where existing.
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.
Replace ExtUtils::MakeMaker with Module::Build.
'perllocal.pod' and 'bindtests.pl' are no longer incorrectly
installed.
This change also removes the following phony deps: appliance src_deps
test_images. No other language binding needs explicit dependencies
for their tests, they just rely on the top level build order being
correct (ie. SUBDIRS in /Makefile.am).
Instead of hardcoding the location of perl (assuming it is installed in
/usr), use /usr/bin/env to run it, and thus picking it from $PATH.
This makes it possible to run these scripts also on installations with
perl in a different prefix than /usr.
Also, given that we want enable warnings on scripts, turn the -w
previously in shebang to explicit "use warnings;" in scripts which
didn't have it before.
This allows the Perl binding of guestfs_add_libvirt_dom to work.
This relies on the internal Perl representation of virDomainPtr, but
Dan assures me this isn't going to change.
This API already existed (as guestfs___add_libvirt_dom), and was used
by a few tools.
This commit changes it to a public API.
Note that for reasons outlined in the previous commit message, it is
impossible to call this from guestfish or from non-C language
bindings.
This changes podwrapper so that the input (POD) files should not
contain an =encoding directive. However they must be UTF-8.
Podwrapper then adds the '=encoding utf8' directive back during final
generation.
This in particular avoids problems with nested =encoding directives in
fragments. These break POD, and are undesirable anyway.
Replaces code such as:
fd = open "test1.img"
ftruncate fd, size
close fd
g.add_drive "test1.img"
with the shorter and simpler:
g.add_drive_scratch size
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.
Despite this change, separated builds are still broken, apparently
because ExtUtils::MakeMaker doesn't support this sort of
configuration, or else we're using it wrong.
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.
