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.
Suggested by David Herrmann.
|
|
|
|
This should not be used for any new code, as we don't set errno in new code,
but there are several legacy users, so let's keep it in shared.

This allows set_action(), read_uevent_file() and read_db() to be made internal to libudev.
|
|
|
|
Udev debug messages have to be significantly overhauled... For now
just downgrade those two. They are responsible for approximately 25%
of debug output during boot and are rather useless.
|
|
Instead introduce ensure_usec_initialized(), which copies the timestamp if possible otherwise
sets it to now(CLOCK_MONOTONIC).
|
|
This allows us to move the db reading from udevd to libudev.
|
|
Return -errno rather than -1 in case sendmsg() fails.
|
|
We were explicitly eagerly loading the db, then deletenig the backing file and then processing the
rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be
lazy as everywhere else.
This may save us a bit of work in casese where the db is not needed, but more importantly it hides
some implementation details of libudev-device form udevd.
|
|
To copy properties from one device to another. Drop the equivalent functionality from udevd.
|
|
|
|
Properties should only be saved to the db when added to the udev_device by udevd, and only if
the property does not start with a '.'. Make this implicit rather than expose the marking of
properties.
|
|
This should be internal to the library as it is only about reflecting the sysfs state in the udev_device.

This patch removes includes that are not used. The removals were found with
include-what-you-use which checks if any of the symbols from a header is
in use.

This reverts commit 93a1e66efd4b0f4cda29c467d20d0f7510c0b3a8.
It broke the builds for Walters.
Kay hates it and "just knows" there are no actual users.
|
|
For two releases those exported with version 183 by mistake, and then
they were fixed to have version 215 (015419c0df libudev: fix symbol
version for udev_queue_flush() and udev_queue_get_fd()). But that
breaks ABI compatibility for binaries compiled with udev from before
that commit. There most likely very few such binaries, if any, but as
a matter of principle we should export the old symbols too, in order
to keep full compatibility.
|
|
include-what-you-use automatically does this and it makes finding
unnecessary harder to spot. The only content of poll.h is a include
of sys/poll.h so should be harmless.
|
|
This reverts commit d6d810fbf8071f8510450dbacd1d083f37603656.
It's apparently not OK to pass MSG_CMSG_CLOEXEC to recvmsg() of raw
sockets.
|
|
|
|
After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.
|
|
|
|
Hide the details a bit.
