Found by coverity. Fixes: CID#996314 and #996312

since 376cd3b89c62f580a6f576cecfbbb28d3944118f LIST_FIND_TAIL accepts
an empty list. That removed an assert in LIST_FIND_TAIL and we now
theoretically risk a null pointer deref. This adds the assert directly
to protect against that.

In programs like eog and gimp the transparant background did not
look very good.
Similar fix from the one done in systemd-analyze (418e3750)

In trying to track down a stupid linker bug, I noticed a bunch of
memset() calls that should be using memzero() to make it more "obvious"
that the options are correct (i.e. 0 is not the length, but the data to
set). So fix up all current calls to memset(foo, 0, length) to
memzero(foo, length).

Use double and not float, as there is little to no benefit.

- Add space between if/for and the opening parentheses
- Place the opening brace on same line as the function (not for udev)
From the CODING_STYLE
Try to use this:
void foo() {
}
instead of this:
void foo()
{
}

each invocation
We can determine the list entry type via the typeof() gcc construct, and
so we should to make the macros much shorter to use.

Since the invention of read-only memory, write-only memory has been
considered deprecated. Where appropriate, either make use of the
value, or avoid writing it, to make it clear that it is not used.

"Corporation" was misspelled as "Coproration"

Instead of storing bootchart sample data in arrays, this patch moves
storage to linked lists so that there is no more limit on samples.
This patch also fixes parsing of /proc/<pid>/smaps in kernels > 3.7.

code in src/shared/macro.h only defined MAX/MIN in case
they were not defined previously. however the MAX/MIN
macros implemented in glibc are not of the "safe" kind but defined
as:
define MIN(a,b) (((a)<(b))?(a):(b))
define MAX(a,b) (((a)>(b))?(a):(b))
Avoid nasty side effects by using our own versions instead.
Also fix the warnings derived from this change.
[zj: - modify MAX3 macro to fix warning about _a shadowing _a,
- do bootchart/svg.c too,
- remove unused MIN3.]

The new gcc isn't bad!

Let's update bootchar to share the coding style a bit more with the rest
of the package.
- Some tabs/spaces fixes
- add #pragma to header
- split up header so that we have a 1:1 relation between .c and .h files
like everywhere else
- Prefix user command line arguments/configuration settings with "arg_".
- other coding style fixes

This reverts commit 0ea9530d401827e299c6e04a433e69a7a2a89d80.
attribute(cleanup) can only be used inside functions (*of, sysfd
are leaked).
Cleanup functions are only called once when exiting scope (*f
is leaked twice).
|
|
use _cleanup_{close_,fclose_} to close streams and file descriptors
|
|
|
|
|
|
|
|
Also parse it early, so that we can get it in the initramfs.

As of [1], bootchart stores files in /run/log, not /var/log, by default.

bootchart.conf: direct users to `bootchart.conf(5)`, not a nonexistent
man page.
svg.c: Fix some English in the svg comment header.
* Chrome/Chromium => Chrome, Chromium
* firefox => Firefox

When we merged systemd-bootchart we omitted relicensing this
to LGPL. Now that code is being used for other purposes we
need to make sure the code is shareable within systemd
without further problems.
The original committers and contributors of bootchart before it
was merged all have agreed with the relicensing.

Bootchart is renamed to 'systemd-bootchart' and installed as
/usr/lib/systemd/systemd-bootchart. The configuration file
will reside in /etc/systemd/bootchart.conf.
