This reverts commit a9e6667817.
Breakage found in the wild: Mockery uses a parent:: call in the
implementation regardless of whether the class has a parent or not:
4324afeaf9/library/Mockery/Mock.php (L600)
This change is not worth the compat break in 7.4.
The sprintf function has been normalized to php_sprintf via
61364b5bb1.
This patch removes the checks to make a custom sprintf function
The ZEND_BROKEN_SPRINTF has been removed and the
hardcoded #define zend_sprintf sprintf is used.
The php_sprintf and zend_sprintf are now symbols to sprintf.
This patch now removes the custom PHP definitions of the php_sprintf and
zend_sprintf functions in favor of the C99 sprintf which is also
standardized in C89 already. Once, on some systems sprintf didn't behave
in same way.
Opcode order changes in 7.4 and the EXT_STMT is now declare the
DECLARE_ANON. Fix this by returning the opline from compile_class_decl
to avoid any fragile opcode searching.
If someone has a better patch, please merge it ASAP, this appears to be correct as I and Nikita originally thought.
Revert "Revert "zend_get_call_op ignoring compiler flags zend_get_call_op will ignore ZEND_COMPILE_IGNORE_USER_FUNCTIONS and ZEND_COMPILE_IGNORE_USER_FUNCTIONS, breaking the intention of these flags""
This reverts commit 0bbbd0f9e7.
This avoids writing this cache at runtime, which is illegal if
preloading is used.
Not every serialize/unserialize function actually belongs to the
Serializable interface, but I think it's not a problem to assign
these anyway -- whether they are used ultimately depends on whether
Serializable is implemented.
Alternatively it might make sense to just drop these entirely. I
don't think this is performance critical functionality.
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.
This is useful for coverage. While it is currently safe to just
skip over the SWITCH_* opcodes, this may not be true in the future
due to opcache optimizations, so it's safer to disable emission of
SWITCH_* opcodes entirely.
RFC: https://wiki.php.net/rfc/null_coalesce_equal_operator
$a ??= $b is $a ?? ($a = $b), with the difference that $a is only
evaluated once, to the degree that this is possible. In particular
in $a[foo()] ?? $b function foo() is only ever called once.
However, the variable access themselves will be reevaluated.
Instead of interleaving creation of live-ranges with the main
compiler code, compute them in a separate pass over the opcodes
as part of pass_two. Additionally, do not keep live ranges
synchronized during optimization in opcache and instead use the
same mechanism to recompute them after optimization.

We already detect the case where we're entirely outside a class --
now also check whether there actually is a parent.
This is a minor BC break, in that code that was never executed
might have previously contained an invalid parent:: reference without
generating an error.
Instead of representing this as a ZEND_AST_CLASS_CONST with a
"class" constant name.
Class constants and ::class are unrelated features that happen to
share syntax, so represent and handle them separately.
Previously this triggered an assertion failure. The behavior is
not quite correct, in that self::class should generate an exception
if there is no self, but returns an empty string here. Fixing that
would be a bit too intrusive for the 7.2 branch.
This does not print the exact line of the comma, but rather the line
of the previous element. This should generally be "good enough", as
the line number is close (off by one) to the actual issue now.
Previously it would point to the start of the array, which may be
very far away.
