sigsetjmp use setjmp. Windows is of course weird in that it seems to
have sigsetjmp but not sigjmp_buf (??) so force it to use setjmp in
config.w32.h.in
consistent in how we deal with the signal mask. POSIX doesn't specify
what to do with the signal mask in setjmp/longjmp which has resulted in
the signal mask getting saved on *BSD and not getting saved on Linux.
Making the behaviour explicit via sigsetjmp/siglongjmp gives us
consistency and saves expensive sigprocmask() syscalls on *BSD.
The following pseudo-code explains how it should be used in opcode cache.
function cache_compile_file($filename) {
if (!is_cached($filename)) {
...
orig_compiler_options = CG(compiler_optins);
CG(compiler_options) |= ZEND_COMPILE_IGNORE_INTERNAL_CLASSES |
ZEND_COMPILE_DELAYED_BINDING;
$op_array = orig_compile_file($filename);
CG(compiler_options) = orig_copiler_options;
...
} else {
$op_array = restore_from_cache($filename);
}
zend_do_delayed_early_binding($op_array);
}
- Added ".htaccess" style user-defined php.ini files support for
CGI/FastCGI.
- Added support for special [PATH=/opt/httpd/www.example.com/] sections
in php.ini. All directives set in these sections will not be able to be
overridden in user-defined ini-files or during runtime in the specified
path.
- Improved php.ini handling:
. Added better error reporting for syntax errors in php.ini files
. Allowed "ini-variables" to be used almost everywhere ini php.ini files
. Allowed using alphanumeric/variable indexes in "array" ini options
. Fixed get_cfg_var() to be able to return "array" ini options
- Fixed bug #27372 (parse error loading browscap.ini at apache startup)
- Fixed bug #42069 (parse_ini_file() allows using some non-alpha numeric
characters)
- Perform implementation checks even with simple inheritance (off when
compatibility mode is enabled).
- Restore default arguments in interfaces and handle it correctly.
- Move registration of internal classes later in the startup sequence
in order to have INI options available.
implementation, and allows exceptions to 'fire' much earlier than before.
Instructions on how to use the new mechanism will follow on internals@
shortly...
Note - this (most probably) breaks the current implementation of
set_exception_handler()
this enables ZE2 to gracefully parse scripts written in UTF-8 (with BOM),
UTF-16, UTF-32, Shift_JIS, ISO-2022-JP etc... (when configured with
'--enable-zend-multibyte' and '--enable-mbstring')
- The fields of zend_namespace were not completely initialized which
led to a variety of problems.
- The occurrence of class/interface/namespace definition is now
captured.
- Functions/classes/interfaces/namespaces can be preceded by doc
comments which are stored for use by extensions.
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
class X { ... }
function bar { ... }
var x = 1;
const ZZ = 2;
}
3. Namespaced symbol access: $x = new foo::X; - etc.
For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).
