The default on Ubuntu 24.04 and newer is now -D_FORTIFY_SOURCE=3 which
clashes with our definition. We shouldnt be setting it for Ubuntus
anyway since _FORTIFY_SOURCE=2 for older distros is already handled by
the defaults in their gcc builds.

Previously, the certificate deletion only handled string type

Add the following tests cases:
1. When "factory" key is used inside the "targets" option.
2. When "factory" key is used at the root level of python application
config.
3. When factory returns invalid callable or When factory is invalid

Adds support for the app factory pattern to the Python language module.
A factory is a callable that returns a WSGI or ASGI application object.
Unit does not support passing arguments to factories.
Setting the `factory` option to `true` instructs Unit to treat the
configured `callable` as a factory.
For example:
"my-app": {
"type": "python",
"path": "/srv/www/",
"module": "hello",
"callable": "create_app",
"factory": true
}
This is similar to other WSGI / ASGI servers. E.g.,
$ uvicorn --factory hello:create_app
$ gunicorn 'hello:create_app()'
The factory setting defaults to false.

The issue was in nxt_tstr_test() where we create an error message with
nxt_sprintf(), where this error message is then later used with the
'%s' format specifier which expects a nul-terminated string, but by
default nxt_sprintf() doesn't nul-terminate, you must use the '%Z'
specifier to signify a '\0' at the end of the string.

This is a temporary support for chunked request bodies by converting
to Content-Length. This allows for processing of such requests until
a more permanent solution is developed.
A new configuration option "chunked_transform" has been added to enable
this feature. The option can be set as follows:
{
"settings": {
"chunked_transform": true
}
}
By default, this option is set to false, which retains the current
behaviour of rejecting chunked requests with a '411 Length Required'
status code.
Please note that this is an experimental implementation.

Previously, Unit didn't move the buffer pointer when parsing chunked
data because the buffer was not used after sent. It's used for upstream
response. With the new requirement to support request chunked body,
the buffer might be used for pipeline request, so it's necessary to move
the pos pointer while parsing.

Build systems should not attempt to create $runstatedir (or anything
under it). Doing so causes warnings in packaging systems, such as in
Alpine Linux, as reported by Andy.
But unitd(8) can be configured to be installed under /opt, or other
trees, where no directories exist before hand. Expecting that the user
creates the entire directory trees that unit will need is a bit
unreasonable. Instead, let's just create any directories that we need,
with all their parents, at run time.

"all" is too generic of an attribute to be meaningful. In the context

"dirname" is the usual way to refer to the directory part of a path
name. See for example dirname(1), or the dirname builtin in several
languages. Also, in the context of mkdir(), "parents" is used to refer
to mkdir -p, which is too similar to "parent", so it can lead to
confusion.

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.
