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 sizeof()s for Content-Length and Transfer-Encoding were missing
the trailing ":". Apart from being generally wrong, this no longer
verified that the header actually contains a colon, leading to the
null http_header_value being used.
Additionally, in the interest of being defensive, also make sure
that http_header_value is non-null by setting it to the end of
the header line (effectively an empty string) if there is no colon.
If the following conditions are correct, this value is not going
to be used though.
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
Rather than trying to modify it mid-request. The protection against
tampering that was used (addref) violates COW because an rc>1 array
is being modified.
Test bug69337.phpt changed because it was testing tampering with
$http_response_header while the HTTP request is being executed.
This simply no longer matters, so behavior is the same as if no
tampering occurred.
The stream handler assumed all HTTP headers contained exactly one space,
but the standard says there may be zero or more. Should fix Bug #47021,
and any other edge cases caused by a web server sending unusual spacing,
e.g. the MIME type discovered from Content-Type: can no longer contain
leading whitespace.
We strip trailing whitespace from the headers added into
$http_response_header as well.
If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I cannot test atm.
