Andrew Clayton a03274456b PHP: allowed to specify URLs without a trailing '/'.
Both @lucatacconi & @mwoodpatrick reported what appears to be the same
issue on GitHub. Namely that when using the PHP language module and
trying to access a URL that is a directory but without specifying the
trailing '/', they were getting a '503 Service Unavailable' error.

Note: This is when _not_ using the 'script' option.

E.g with the following config

  {
      "listeners": {
          "[::1]:8080": {
              "pass": "applications/php"
          }
      },

      "applications": {
          "php": {
              "type": "php",
              "root": "/var/tmp/unit-php"
          }
      }
  }

and with a directory path of /var/tmp/unit-php/foo containing an
index.php, you would see the following

  $ curl http://localhost/foo
  <title>Error 503</title>
  Error 503

However

  $ curl http://localhost/foo/

would work and serve up the index.php

This commit fixes the above so you get the desired behaviour without
specifying the trailing '/' by doing the following

  1] If the URL doesn't end in .php and doesn't have a trailing '/'
     then check if the requested path is a directory.

  2) If it is a directory then create a 301 re-direct pointing to it.
     This matches the behaviour of the likes of nginx, Apache and
     lighttpd.

     This also matches the behaviour of the "share" action in Unit.

This doesn't effect the behaviour of the 'script' option which bypasses
the nxt_php_dynamic_request() function.

This also adds a couple of tests to test/test_php_application.py to
ensure this continues to work.

Andrew Clayton 58248a6220 Fixed some function definitions.
Future releases of GCC will render function definitions like

  func()

invalid by default. See the previous commit 09f88c9 ("Fixed main()
prototypes in auto tests.") for details.

Such functions should be defined like

  func(void)

This is a good thing to do regardless of the upcoming GCC changes.

Andrew Clayton 8f0dd9478e Fixed main() prototypes in auto tests.
Future releases of GCC are planning to remove[0] default support for
some old features that were removed from C99 but GCC still accepts.

We can test for these changes by using the following -Werror=
directives

  -Werror=implicit-int
  -Werror=implicit-function-declaration
  -Werror=int-conversion
  -Werror=strict-prototypes
  -Werror=old-style-definition

Doing so revealed an issue with the auto/ tests in that the test
programs always define main as

  int main()

rather than

  int main(void)

which results in a bunch of errors like

build/autotest.c:3:23: error: function declaration isn't a prototype [-Werror=strict-prototypes]
    3 |                   int main() {
      |                       ^~~~
build/autotest.c: In function 'main':
build/autotest.c:3:23: error: old-style function definition [-Werror=old-style-definition]

The fix was easy, it only required fixing the main prototype with

  find -type f -exec sed -i 's/int main() {/int main(void) {/g' {} \;

Regardless of these upcoming GCC changes, this is probably a good thing
to do anyway for correctness.

Andrew Clayton 7a928b33b4 Set git diff driver for C source code files.
Git can be told to apply language-specific rules when generating diffs.
Enable this for C source code files (*.c and *.h) so that function names
are printed right. Specifically, doing so prevents "git diff" from
mistakenly considering unindented goto labels as function names.

This has the same effect as adding

    [diff "default"]
        xfuncname = "^[[:alpha:]$_].*[^:]$"

to your git config file.

Andrew Clayton f8b892e1fa Fixed the build on MacOS (and others).
@alejandro-colomar reported that the build was broken on MacOS

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [build/unitd] Error 1

This was due to commit 57fc920 ("Socket: Created control socket & pid file
directories.").

This happened because this commit introduced the usage of
nxt_fs_mkdir_parent() in core code which uses nxt_fs_mkdir(), both of
these are defined in src/nxt_fs.c. It turns out however that this file
doesn't get built on MacOS (or any system that isn't Linux or that
lacks a FreeBSD compatible nmount(2) system call) due to the following

In auto/sources we have

  if [ $NXT_HAVE_ROOTFS = YES ]; then
      NXT_LIB_SRCS="$NXT_LIB_SRCS src/nxt_fs.c"
  fi

NXT_HAVE_ROOTFS is set in auto/isolation

  If [ $NXT_HAVE_MOUNT = YES -a $NXT_HAVE_UNMOUNT = YES ]; then
      NXT_HAVE_ROOTFS=YES

      cat << END >> $NXT_AUTO_CONFIG_H
  #ifndef NXT_HAVE_ISOLATION_ROOTFS
  #define NXT_HAVE_ISOLATION_ROOTFS  1
  #endif
  END

  fi

While we do have a check for a generic umount(2) which is found on
MacOS, for mount(2) we currently only check for the Linux mount(2) and
FreeBSD nmount(2) system calls. So NXT_HAVE_ROOTFS is set to NO on MacOS
and we don't build src/nxt_fs.c

This fixes the immediate build issue by taking the mount/umount OS
support out of nxt_fs.c into a new nxt_fs_mount.c file which is guarded
by the above while we now build nxt_fs.c unconditionally.

This should fix the build on any _supported_ system.

Andrew ClaytonandAndrew Clayton 57fc9201cb Socket: Created control socket & pid file directories.
@alejandro-colomar reported an issue on GitHub whereby Unit would fail
to start due to not being able to create the control socket (a Unix
Domain Socket)

  2022/08/05 20:12:22 [alert] 21613#21613 bind(6,
  unix:/opt/local/unit/var/run/unit/control.unit.sock.tmp)
  failed (2: No such file or directory)

This could happen if the control socket was set to a directory that
doesn't exist. A common place to put the control socket would be under
/run/unit, and while /run will exist, /run/unit may well not (/run
is/should be cleared on each boot).

The pid file would also generally go under /run/unit, though this is
created after the control socket, however it could go someplace else so
we should also ensure its directory exists.

This commit will try to create the pid file and control sockets parent
directory. In some cases the user will need to ensure that the rest of
the path already exists.

This adds a new nxt_fs_mkdir_parent() function that given a full path
to a file (or directory), strips the last component off before passing
the remaining directory path to nxt_fs_mkdir().

Andrew Clayton 2e69b7eb57 Added a .mailmap file.
This file is used by git (maybe also hg) to map different identities.

It can be used to map different names/email addresses to a preferred
name/email. So if you have authored/committed under different
names/email addresses you can map all these to a particular name/email.
Certain git commands (log, shortlog, show, blame etc) will consult this
file and show the Author/Committer accordingly.

Note: This does _not_ change history, this is simply used by various
commands to alter their output and can be disabled for some commands
with the --no-mailmap option.

This can be useful for commands like git shortlog so that all your
commits are shown under a single identity and also so people have an
up to date email address should they wish to contact you. And just for
overall consistency.

Seeing as I've already committed under two different email addresses
(not counting this one), I've put entries in this file to map my email
addresses to my @nginx.com one.

See also, gitmailmap(5).
