Previously we were a bit sloppy with the index and size types of arrays,
we'd regularly use unsigned. While I don't think this ever resulted in
real issues I think we should be more careful there and follow a
stricter regime: unless there's a strong reason not to use size_t for
array sizes and indexes, size_t it should be. Any allocations we do
ultimately will use size_t anyway, and converting forth and back between
unsigned and size_t will always be a source of problems.
Note that on 32bit machines "unsigned" and "size_t" are equivalent, and
on 64bit machines our arrays shouldn't grow that large anyway, and if
they do we have a problem, however that kind of overly large allocation
we have protections for usually, but for overflows we do not have that
so much, hence let's add it.
So yeah, it's a story of the current code being already "good enough",
but I think some extra type hygiene is better.
This patch tries to be comprehensive, but it probably isn't and I missed
a few cases. But I guess we can cover that later as we notice it. Among
smaller fixes, this changes:
1. strv_length()' return type becomes size_t
2. the unit file changes array size becomes size_t
3. DNS answer and query array sizes become size_t

Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

This macro will read a pointer of any type, return it, and set the
pointer to NULL. This is useful as an explicit concept of passing
ownership of a memory area between pointers.
This takes inspiration from Rust:
https://doc.rust-lang.org/std/option/enum.Option.html#method.take
and was suggested by Alan Jenkins (@sourcejedi).
It drops ~160 lines of code from our codebase, which makes me like it.
Also, I think it clarifies passing of ownership, and thus helps
readability a bit (at least for the initiated who know the new macro)

Let's systematically make use of reallocarray() whereever we invoke
realloc() with a product of two values.
|
| |
|
|
|
|
|
|
| |
There isn't much difference, but in general we prefer to use the standard
functions. glibc provides reallocarray since version 2.26.
I moved explicit_bzero is configure test to the bottom, so that the two stdlib
functions are at the bottom.

The function `strv_join_quoted()` is now not used, and has a bug
in the buffer size calculation when the strings needs to escaped,
as reported in #8056.
So, let's remove the function.
Closes #8056.

strv_sort() predates qsort_safe(), but we can convert it to it to
save a few lines.

These functions, although not used by elogind itself, are mostly tiny
and crucial for important tests to work.

This reverts commit 18f71a3c8174774c5386c4aba94d54f3b5c36a84.
According to @keszybz we don't need this anymore, hence drop it:
https://github.com/elogind/elogind/pull/5131/commits/18f71a3c8174774c5386c4aba94d54f3b5c36a84#r102232368

All callers of this function insert non-empty strings, so there's no functional
change.

With this change the logic for placing transient unit files and drop-ins
generated via "systemctl set-property" is reworked.
The latter are now placed in the newly introduced "control" unit file
directory. The fomer are now placed in the "transient" unit file directory.
Note that the properties originally set when a transient unit was created will
be written to and stay in the transient unit file directory, while later
changes are done via drop-ins.
This is preparation for a later "systemctl revert" addition, where existing
drop-ins are flushed out, but the original transient definition is restored.

Empty strings were ignored in strv_join, but only if they were at the beginning
of the string. Empty strings after at least one non-empty item were treated
normally.
Previously:
{"x"} → "x"
{"x", ""} → "x"
{"x", "", ""} → "x::"
{""} → ""
{"", ""} → ""
{"", "", ""} → ""
{"", "x"} → "x"
{"", "x", ""} → "x:"
Now:
{"x"} → "x"
{"x", ""} → "x"
{"x", "", ""} → "x::"
{""} → ""
{"", ""} → ":"
{"", "", ""} → "::"
{"", "x"} → ":x"
{"", "x", ""} → ":x:"

This commit replays the moving around of source files that have been
done between systemd-219 and systemd-221.
Further the Makefile.am is synchronized with the upstream version and
then "re-cleaned".
A lot of functions, that are not used anywhere in elogind have been
coated into #if 0/#endif directives to further shorten the list of
dependencies.
All unneeded files have been removed.
