The 'Group' and 'BuildRoot' tags have been declared as deprecated by the
Fedora project.
Also, to quote the Fedora Packaging Guidelines
The contents of the buildroot SHOULD NOT be removed in the first line
of %install.
The %defattr directive in the %files list SHOULD ONLY be used when
setting a non-default value, or to reset to the default value after
having set a non-default value.

This was found via MSan.
In nxt_http_fields_hash() we setup a nxt_lvlhsh_query_t structure and
initialise a couple of its members.
At some point we call
lhq->proto->alloc(lhq->pool, nxt_lvlhsh_bucket_size(lhq->proto));
Which in this case is
void *
nxt_lvlhsh_alloc(void *data, size_t size)
{
return nxt_memalign(size, size);
}
So even though lhq.ppol wasn't previously initialised we don't actually
use it in that particular function.
However MSan triggers on the fact that we are passing an uninitialised
value into that function.
Indeed, compilers will generally complain about such things, e.g
/* u.c */
struct t {
void *p;
int len;
};
static void test(void *p __attribute__((unused)), int len)
{
(void)len;
}
int main(void)
{
struct t t;
t.len = 42;
test(t.p, t.len);
return 0;
}
GCC and Clang will produce a -Wuninitialized warning.
But they won't catch the following...
/* u2.c */
struct t {
void *p;
int len;
};
static void _test(void *p __attribute__((unused)), int len)
{
(void)len;
}
static void test(struct t *t)
{
_test(t->p, t->len);
}
int main(void)
{
struct t t;
t.len = 42;
test(&t);
return 0;
}
Which is why we don't get a compiler warning about lhq.pool.
In this case initialising lhg.pool even though we don't use it here
seems like the right thing to do and maybe compilers will start being
able to catch these in the future.
Actually GCC with -fanalyzer does catch the above
$ gcc -Wall -Wextra -O0 -fanalyzer u2.c
u2.c: In function ‘test’:
u2.c:15:9: warning: use of uninitialized value ‘*t.p’ [CWE-457] [-Wanalyzer-use-of-uninitialized-value]

This patch does a number of things to help when failing to apply a new
configuration.
* The error body from the Unit control API is displayed which can have
useful troubleshooting information (when the version of curl supports it).
* When using the EDIT option, the temporary file with unapplied changes is
preserved so that the user can edit it again without losing their work.
* Editing JavaScript modules no longer requires that module to have been
enabled.
* Failure to apply edited JavaScript modules now rolls-back to the previous
configuration instead of deleting the module.

The lists of files being unpacked are mostly useless but take a
significant amount of lines and bytes in e.g. CI jobs. E.g. in rhel9
packaging job, it's 39680 lines just for the unpacking of
wasmtime-v11.0.1-src, as compared to total 48945 lines of output.

dpkg-query -W will show information about the package if any other
package references it, even when the queried package is not installed.

This adds a workflow for building Unit under Fedora Rawhide and Alpine
Edge with both GCC and Clang.
These are the development branches from which releases are cut.
This usually consists of the latest versions of software and will
hopefully catch new compiler issues and API breakages in the various
languages we support.
With Alpine and Clang that also gives us musl libc + clang coverage.
On Alpine we don't build the wasm and wasm-wasi-component modules,
mainly as this would require messing around with all the rust stuff and
building wasmtime from source (as there's no musl libc based packages)
and the wasm module is pretty small, any new compiler issues would
hopefully show up in the rest.
We _do_ build the wasm module with gcc and clang on Fedora. But not
wasm-wasi-component in the interests of time. Can be added at a later
date if deemed necessary.
We don't build the Perl language module on Fedora with clang due to the
Fedora (and probably Red Hat) Perl CFLAGS having incompatible with clang
flags.
We probably could work around it if we really wanted to, but not sure
it's worth it and on Red Hat/Fedora, GCC _is_ the system compiler.
On Alpine we also don't build the nodejs and go language modules as
there's nothing that actually gets compiled there and the _main_ reason
for building on Alpine is to get musl libc + clang coverage.
We're also not bothering with njs for now... can be revisited at a
later date.
Also no pytests, these should be well covered via other workflows for
example by running on latest Alpine releases.

Previously, the REQUEST_URI within Unit could be modified,
for example, during uri rewriting. We decide to make $request_uri
immutable and pass constant REQUEST_URI to applications.
Based on the new requirement, we remove `r->target` rewriting
in the rewrite module.

When we added -fno-strict-overflow to the CFLAGS back in c1e3f02f9
("Compile with -fno-strict-overflow") we inadvertently broke building
the Perl language module with clang, e.g
$ make
CC build/src/perl/nxt_perl_psgi-perl.o
clang: error: argument unused during compilation: '-fno-strict-overflow' [-Werror,-Wunused-command-line-argument]
This is due to for example on Apline
$ perl -MExtUtils::Embed -e ccflags
-D_REENTRANT -D_GNU_SOURCE -D_GNU_SOURCE -fwrapv -fno-strict-aliasing -pipe -fstack-protector-strong -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64
Where on clang the -fwrapv causes the -fno-strict-overflow to be
discarded resulting in the above error.
We can get around that by simply appending -Qunused-arguments to the
Perl CFLAGS.
This fixes things for _some_ systems, as there is actually another issue
with building this with clang on Fedora (and probably Red Hat) in that
there the Perl ccflags & ldopts have been heavily modified and uses
flags simply not only not in clang (which we can work around as above)
but also incompatible flags, e.g
$ make perl
CC build/src/perl/nxt_perl_psgi-perl.o
clang: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]
There doesn't seem to be an easy workaround like -Qunused-arguments for
this.
While we could work around it in some way, I'm not sure it's worth the
effort right now. On Red Hat & Fedora GCC _is_ the system compiler.
This could be revisited if we find people trying to build this on
Red Hat/Fedora with clang...
For comparison this is the Alpine Perl ccflags & ldops
$ perl -MExtUtils::Embed -e ccflags

Declaring a 0-sized array (e.g 'char arr[0];') as the last member of a
structure is a GNU extension that was used to implement flexible array
members (FAMs) before they were standardised in C99 as simply '[]'.
The GNU extension itself was introduced to work around a hack of
declaring 1-sized arrays to mean a variable-length object. The advantage
of the 0-sized (and true FAMs) is that they don't count towards the size
of the structure.
Unit already declares some true FAMs, but it also declared some 0-sized
arrays.
Converting these 0-sized arrays to true FAMs is not only good for
consistency but will also allow better compiler checks now (as in a C99
FAM *must* be the last member of a structure and the compiler will warn
otherwise) and in the future as doing this fixes a bunch of warnings
(treated as errors in Unit by default) when compiled with
-O2 -Warray-bounds -Wstrict-flex-arrays -fstrict-flex-arrays=3
(Note -Warray-bounds is enabled by -Wall and -Wstrict-flex-arrays seems
to also be enabled via -Wall -Wextra, the -02 is required to make
-fstrict-flex-arrays more effective, =3 is the default on at least GCC
14)
such as
CC build/src/nxt_upstream.o
src/nxt_upstream.c: In function ‘nxt_upstreams_create’:
src/nxt_upstream.c:56:18: error: array subscript i is outside array bounds of ‘nxt_upstream_t[0]’ {aka ‘struct nxt_upstream_s[]’} [-Werror=array-bounds=]
56 | string = nxt_str_dup(mp, &upstreams->upstream[i].name, &name);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from src/nxt_upstream.c:9:
src/nxt_upstream.h:55:48: note: while referencing ‘upstream’
55 | nxt_upstream_t upstream[0];
| ^~~~~~~~
Making our flexible array members proper C99 FAMs and ensuring any >0
sized trailing arrays in structures are really normal arrays will allow
to enable various compiler options (such as the above and more) that
will help keep our array usage safe.
Changing 0-sized arrays to FAMs should have no effect on structure
layouts/sizes (they both have a size of 0, although doing a sizeof() on
a FAM will result in a compiler error).
Looking at pahole(1) output for the nxt_http_route_ruleset_t structure
for the [0] and [] cases...
$ pahole -C nxt_http_route_ruleset_t /tmp/build/src/nxt_http_route.o
typedef struct {
uint32_t items; /* 0 4 */
/* XXX 4 bytes hole, try to pack */
nxt_http_route_rule_t * rule[]; /* 8 0 */
/* size: 8, cachelines: 1, members: 2 */
/* sum members: 4, holes: 1, sum holes: 4 */
/* last cacheline: 8 bytes */
} nxt_http_route_ruleset_t;

/* sum members: 4, holes: 1, sum holes: 4 */
/* last cacheline: 8 bytes */
} nxt_http_route_ruleset_t;

shows no changes to their sizes

This continues the patch series constifying various pointers in the
configuration sub-system.
This is done as a separate commit as it involved a _slightly_ more
invasive change in nxt_conf_get_string().
While it takes a value parameter that is never modified, simply making
it const results in
CC build/src/nxt_conf.o
src/nxt_conf.c: In function ‘nxt_conf_get_string’:
src/nxt_conf.c:170:20: error: assignment discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]

due to the assignment operator. Making value const will allow for
numerous other constification and seeing as we are not modifying it,
seems worthwhile.
We can get around the warning by casting ->u.{str,string}.start
