For some reason they were missed previously. All those files seem to
have proper SDPX tags.
This drops a good number of type-specific _cleanup_ macros, and patches
all users to just use the generic ones.
In most recent code we abstained from defining type-specific macros, and
this basically removes all those added already, with the exception of
the really low-level ones.
Having explicit macros for this is not too useful, as the expression
without the extra macro is generally just 2ch wider. We should generally
emphesize generic code, unless there are really good reasons for
specific code, hence let's follow this in this case too.
Note that _cleanup_free_ and similar really low-level, libc'ish, Linux
API'ish macros continue to be defined, only the really high-level OO
ones are dropped. From now on this should really be the rule: for really
low-level stuff, such as memory allocation, fd handling and so one, go
ahead and define explicit per-type macros, but for high-level, specific
program code, just use the generic _cleanup_() macro directly, in order
to keep things simple and as readable as possible for the uninitiated.
Note that before this patch some of the APIs (notable libudev ones) were
already used with the high-level macros at some places and with the
generic _cleanup_ macro at others. With this patch we hence unify on the
latter.
This adds missing options, mainly '--version' in getopt(), removes
an unused option from getopt().
Also, this adds a deprecate message in `udevadm hwdb`, and cleanups
help messages.
Follow-up for 65eb4378c3.
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.
If replace_whitespace is true, each substitution value has all its
whitespace removed/replaced by util_replace_whitespace (except the
SUBST_RESULT substitution - $result{} or %c{} - which handles spaces
itself as field separators). All existing callers are updated to
pass false, so no functional change is made by this patch.
This is needed so the SYMLINK assignment can replace any spaces
introduced through variable substitution, becuase the SYMLINK value is
a space-separated list of symlinks to create. Any variables that
contain spaces will thus unexpectedly change the symlink value from
a single symlink to multiple incorrectly-named symlinks.
This is used in the next patch, which enables the whitespace
replacement for SYMLINK variable substitution.
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.
We used to block all signals, and restore the original signal mask before exec'ing
external processes.
Now we just block the signals we care about and unconditionally unblock all signals
before exec'ing.
This allows us to drop the special sigterm handling in spawn_wait()
as this will now be passed directly to the worker event loop.
We now log failing spawend processes at 'warning' level, and timeouts
are in terms of CLOCK_BOOTTIME when available, otherwise the behavior
is unchanged.
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.
