Prior to the 8.1 rewrite, inet_aton was used for ipv4 addresses
therefore addresses like `0` passed.
For the bindto's case where both ip and port are set as such, we discard
the address binding.
Close GH-12195
When you choose to bind() to a local address and connect to a remote host
the kernel does not know if socket is listener or whatnot and has to reserve
a port within a ~32k range on which you are also competing with other
applications bound to the same address, this is easy to exhaust and get a
EADDRINUSE.
The linux kernel implemented IP_BIND_ADDRESS_NO_PORT on
90c337da15
which delays the port allocation until the 4-tuple is known in case source port
is 0.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

A recent commit[1] which fixed a memory leak introduced a regression
regarding the formerly liberal handling of IP addresses to bind to. We
fix this by reverting that commit, and fix the memory leak where it
actually occurs. In other words, this fix is less intrusive than the
former fix.

Closes GH-6104.
The `timercmp()` manpage[1] points out that some systems have a broken
implementation which does not support `>=`. This is definitely the
case for the Windows SDK, which only supports `<` and `>`.

This is actually about three distinct issues:
* If an empty string is passed as $address to `stream_socket_sendto()`,
the `sa` is not initialized, so we must not pass it as `addr` to
`php_stream_xport_sendto()`.
* On POSIX, `recvfrom()` truncates messages which are too long to fit
into the specified buffer (unless `MSG_PEEK` is given), discards the
excessive bytes, and returns the buffer length. On Windows, the same
happens, but `recvfrom()` returns `SOCKET_ERROR` with the error code
`WSAEMSGSIZE`. We have to catch this for best POSIX compatibility.
* In `php_network_parse_network_address_with_port()`, we have to zero
`in6` (not only its alias `sa`) to properly support IPv6.

Actually, `max_fd` is not used on Windows, since `PHP_SAFE_MAX_FD` and
`select` ignore it; so it makes no sense to calculate it in the loop.
Even worse, since `php_socket_t` is unsigned on Windows, it will never
be modified during the loop, because `SOCK_ERR` is already the largest
representable value of that type.
Therefore we skip the loop on Windows, and add a clarifying comment.
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
The FormatMessage API needs to LocalFree the delivered error messages.
In cases where messages are delivered in non ASCII compatible encoding,
the messages might be unreadable. This aligns the error message encoding
with the encoding settings in PHP, the focus is UTF-8 as default.
Initialize error buffer
Avoid code duplication
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
The IPv6 IP of a socket is provided by inet_ntop() as a string, but
this function doesn't enclose the IP in brackets. This patch adds
them in the php_network_populate_name_from_sockaddr() function.
This patch however does not drop support for the BeOS compatible variant, Haiku, see Github PR #2697 which is currently a WiP
I intentionally left out some fragments for BeOS in the build system for that seems to be bundles
