  Introduce extra counter to avoid RTD key collisions
 2019-12-13 11:05:41 +01:00
Nikita Popov
0f2cdbf214 Introduce extra counter to avoid RTD key collisions 
Also generate a fatal error if a collision occurs in zend_compile.

This is not perfect, because collisions might still be introduced
via opcache, if one file is included multiple times during a request,
invalidate in the meantime and recompiled by different processes.

This still needs to be addressed, but this patch fixes the much
more common case of collisions occuring when opcache is not used.

Fixes bug #78903.

be89a5c7f1 Fixed bug #78950: Preloading trait method with static variables 
We need to make sure that trait methods with static variables
allocate a separate MAP slot for the static variables pointer,
rather than working in-place.

loop range. Skip FE_FREEs with the FREE_ON_RETURN flag.

1695d3ed07 Add funcinfo for spl global functions 
This assumes that `iterator_*` will now always throw or abort on failure.

Also, move #include _arginfo.h directive to the top of the file - virtually all
other files put it there, and developers may base code on basic_functions.c.

Closes GH-4968

d6f86caa11 Fix release build failure 
GCC complained about potentially uninitialized __orig_bailout,
even though the variable has an initializer. This warning was
quite persistent, I was only able to avoid it by using a separate
function.

Am I missing something?

Now it's like:

3f86adb0ef Fixed bug #78935: Check that all linked classes can be preloaded 
During preloading, check that all classes that have been included
as part of the preload script itself (rather than through opcache_compile_file)
can actually be preloaded, i.e. satisfy Windows restrictions, have
resolved initializers and resolved property types. When resolving
initializers and property types, also autoload additional classes.
Because of this, the resolution runs in a loop.

e0a8c7a8d0 Remove CV limitation when determining value from type in SCCP 
As far as I can determine, this is no longer a problem: We will
not try to remove the defining instructions (this is only done if
the value is known by SCCP itself) and we also only determine
non-refcounted values in this way, so it is not a problem if the
FREE is omitted.
