The indentation for emacs'es meson-mode is added .dir-locals.
All files are reindented automatically, using the lasest meson-mode from git.
Indentation should now be fairly consistent.
|
|
This simplifies things and leads to a smaller installation footprint.
libsystemd_internal and libsystemd_journal_internal are linked into
libystemd-shared and available to all programs linked to libsystemd-shared.
libsystemd_journal_internal is not needed anymore, and libsystemd-shared
is used everwhere. The few exceptions are: libsystemd.so, test-engine,
test-bus-error, and various loadable modules.

With mesonbuid/meson#1545, meson does not propagate deps of a library
when linking with that library. That's of course the right thing to do,
but it exposes a bunch of missing deps.
This compiles with both meson-0.39.1 and meson-git + pr/1545.
|
|
This is slightly complicated by the fact that files('libudev.h') cannot be used
as an argument in custom_target command (string is required). This restriction
should be lifted in future versions of mesons, so this could be simplified.
|
|
This is pretty ugly, because I don't know how to use a single
definition for two purposes:
- --version-script needs a path relative to the build root
- link_depends needs a path relative to source root
Also, link_depends does not accept files() output
[https://github.com/mesonbuild/meson/issues/1172], and I don't see a way to go
from files() output to a string path that can be used to craft the -Wl arg.
Ideally, a single files() result could be used in both places.
I'm leaving this as a separate commit for now.

It's crucial that we can build systemd using VS2010!
... er, wait, no, that's not the official reason. We need to shed old systems
by requring python 3! Oh, no, it's something else. Maybe we need to throw out
345 years of knowlege accumulated in autotools? Whatever, this new thing is
cool and shiny, let's use it.
This is not complete, I'm throwing it out here for your amusement and critique.
- rules for sd-boot are missing. Those might be quite complicated.
- rules for tests are missing too. Those are probably quite simple and
repetitive, but there's lots of them.
- it's likely that I didn't get all the conditions right, I only tested "full"
compilation where most deps are provided and nothing is disabled.
- busname.target and all .busname units are skipped on purpose.
Otherwise, installation into $DESTDIR has the same list of files and the
autoconf install, except for .la files.
It'd be great if people had a careful look at all the library linking options.
I added stuff until things compiled, and in the end there's much less linking
then in the old system. But it seems that there's still a lot of unnecessary
deps.
meson has a `shared_module` statement, which sounds like something appropriate
for our nss and pam modules. Unfortunately, I couldn't get it to work. For the
nss modules, we need an .so version of '2', but `shared_module` disallows the
version argument. For the pam module, it also didn't work, I forgot the reason.
The handling of .m4 and .in and .m4.in files is rather awkward. It's likely
that this could be simplified. If make support is ever dropped, I think it'd
make sense to switch to a different templating system so that two different
languages and not required, which would make everything simpler yet.
v2:
- use get_pkgconfig_variable
- use sh not bash
- use add_project_arguments
v3:
- drop required:true and fix progs/prog typo
v4:
- use find_library('bz2')
- add TTY_GID definition
- define __SANE_USERSPACE_TYPES__
- use join_paths(prefix, ...) is used on all paths to make them all absolute
v5:
- replace all declare_dependency's with []
- add more conf.get guards around optional components
v6:
- drop -pipe, -Wall which are the default in meson
- use compiler.has_function() and compiler.has_header_symbol instead of the
hand-rolled checks.
- fix duplication in 'liblibsystemd' library name
- use the right .sym file for pam_systemd
- rename 'compiler' to 'cc': shorter, and more idiomatic.
v7:
- use ENABLE_ENVIRONMENT_D not HAVE_ENVIRONMENT_D
- rename prefix to prefixdir, rootprefix to rootprefixdir
("prefix" is too common of a name and too easy to overwrite by mistake)
- wrap more stuff with conf.get('ENABLE...') == 1
- use rootprefix=='/' and rootbindir as install_dir, to fix paths under
split-usr==true.
v8:
- use .split() also for src/coredump. Now everything is consistent ;)
- add rootlibdir option and use it on the libraries that require it
v9:
- indentation
v10:
- fix check for qrencode and libaudit
v11:
- unify handling of executable paths, provide options for all progs
This makes the meson build behave slightly differently than the
autoconf-based one, because we always first try to find the executable in the
filesystem, and fall back to the default. I think different handling of
loadkeys, setfont, and telinit was just a historical accident.
In addition to checking in $PATH, also check /usr/sbin/, /sbin for programs.
In Fedora $PATH includes /usr/sbin, (and /sbin is is a symlink to /usr/sbin),
but in Debian, those directories are not included in the path.
C.f. https://github.com/mesonbuild/meson/issues/1576.
- call all the options 'xxx-path' for clarity.
- sort man/rules/meson.build properly so it's stable

We defined both $(VERSION) and $(PACKAGE_VERSION) with the same contents.
$(PACKAGE_VERSION) is slightly more descriptive, so settle on that, and
drop the other define.

This reverts commit c22569eeeafa94cf510267071f5b75c4ab714e09.
Let's revert this for now, since it apparently doesn't fix the problem
at hand.

As per commit 25e773e "udev: switch to systemd logging functions"
Now log_set_max_level() in udev_new() overwites system wide log level.
Propagate the udev.conf setting to log_set_max_level()
only if udev_new() is called from within udevd or one of its helpers.
Introduce a UDEV_PROPAGATE_LOG macro that we set with -D on
the gcc command line for all udev binaries we build, but not
for any others. The log_set_max_level() call is guarded by an
ifdef check for that macro, so that it only effects the various
udev binaries.
closes: #4525

Instead of using a temp buffer to replace whitespace in variable
substitutions, just allow util_replace_whitespace to replace in-place.
Add a comment to util_replace_whitespace indicating it is used to replace
in-place, to prevent accidental future breakage.
|
|
Instead of returning 0, which is unhelpful, return the number of chars
copied into the dest string. This allows callers that care about that
to easily use it, instead of having to calculate the strlen.
No current users of the function check the return value, so this does not
break any existing code; it is used in the following patch.
|
|
All other constructors in libudev do that, let's also do this for udev_new().
|
|
It is possible to specify only one quote in udev rules, which is not
detected as an invalid quoting (" instead of "" for empty string).
Technically this doesn't lead to a bug, because the string ends in two
terminating nul characters at this position, but a user should still be
reminded that his configuration is invalid.

Format string tweaks (and a small fix on 32bit)
|
|
The .so symlinks got moved to rootlibdir in 082210c7.
|
|
We don't have plural in the name of any other -util files and this
inconsistency trips me up every time I try to type this file name
from memory. "formats-util" is even hard to pronounce.

Super-important change, yeah!
|

Since glibc is moving away from implicitly including sys/sysmacros.h
all the time via sys/types.h, include the header directly in more
places. This seems to cover most makedev/major/minor usage.
|
|
Throughout the tree there's spurious use of spaces separating ++ and --
operators from their respective operands. Make ++ and -- operator
consistent with the majority of existing uses; discard the spaces.
|
|
Usually, we place the #pragma once before the copyright blurb in header files,
but in a few cases we didn't. Move those around, so that we do the same thing
everywhere.

GLIB has recently started to officially support the gcc cleanup
attribute in its public API, hence let's do the same for our APIs.
With this patch we'll define an xyz_unrefp() call for each public
xyz_unref() call, to make it easy to use inside a
__attribute__((cleanup())) expression. Then, all code is ported over to
make use of this.
The new calls are also documented in the man pages, with examples how to
use them (well, I only added docs where the _unref() call itself already
had docs, and the examples, only cover sd_bus_unrefp() and
sd_event_unrefp()).
This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we
tend to call our destructors these days.
Note that this defines no public macro that wraps gcc's attribute and
makes it easier to use. While I think it's our duty in the library to
make our stuff easy to use, I figure it's not our duty to make gcc's own
features easy to use on its own. Most likely, client code which wants to
make use of this should define its own:
#define _cleanup_(function) __attribute__((cleanup(function)))
Or similar, to make the gcc feature easier to use.
Making this logic public has the benefit that we can remove three header
files whose only purpose was to define these functions internally.
See #2008.

This is a continuation of the previous include sort patch, which
only sorted for .c files.
|
|
|

Sort the includes accoding to the new coding style.

There are more than enough to deserve their own .c file, hence move them
over.
|
|
string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

This replaces this:
free(p);
p = NULL;
by this:
p = mfree(p);

We were adding the attributes to the wrong list.

This was a regression introduced when moving to sd-device.

udev_monitor_new_from_netlink_fd
This allows a fd to be created and configured as part of one monitor, to be passed in
to create a second monitor without having to redo any of the configuration.

This reverts b67f944. Lazy loading of device properties does not work for devices
that are received over netlink, as these are sealed. Reinstate the unconditional
loading of the device db.
Reported by: Mantas Mikulėnas <grawity@gmail.com>.
|
|
If the underlying device has not read in the properties yet, the generation will be 0, so
make sure we trigger the reading at least once.
|
|
It is still possible to include uninitialized ones, but now that is opt-in. In most
cases people only want initialized devices. Exception is if you want to work without
udev running.

This is rarely, if ever, used. Drop it from the new public API and only keep it for
the legacy API.
