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.
I've introduced a new CompileError type, from which ParseError
inherits. These errors are not parse errors in the narrow sense
of the term, even though they happen to be generated during
parsing in our implementation. Additionally reusing the ParseError
class for this purpose would change existing error messages (if
the exception is not caught) from a "Fatal error:" to a "Parse
error:" prefix, and also the error kind from E_COMPILE_ERROR to
E_PARSE.
This reverts commit a2c7c46d5e.
Since apparently there have been some mistakes in this commit, and it's
not clear yet how to solve them, we're reverting for now.
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.
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings
- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end
There is no runtime interning.
With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
It's annoying that in Zend you have to use zend_strpprintf instead
of strpprintf, while in PHP you have to use strpprintf instead of
zend_strpprintf.
Make zend_s(tr)pprintf always available and keep s(tr)pprintf as
macro aliases.
