We already changed the behavior for __set() in f1848a4. However, it
seems that this is also a problem for all the other property magic,
see bug #78904.
This commit makes the behavior of all the property magic consistent:
Magic will not be triggered for uninitialized typed properties, only
explicitly unset() ones. This brings behavior more in line how
non-typed properties behave and avoids WTF.
Closes GH-4974.
Assigning to an uninitialized typed property will no longer trigger
a call to __set(). However, calls to __set() are still triggered if
the property is explicitly unset().
This gives us both the behavior people generally expect, and still
allows ORMs to do lazy initialization by unsetting properties.
For PHP 8, we should fine a way to forbid unsetting of declared
properties entirely, and provide a different way to achieve lazy
initialization.
This goes in the reverse direction of 4463acb951.
After looking around a bit, it seems that we already check for
Z_ISERROR_P() on the get_property_ptr_ptr return value in other places.
So do this in zend_fetch_property_address() as well, and also make
sure that EG(error_zval) is indeed returned on exception in
get_property_ptr_ptr.
In particular, this fixes the duplicate exceptions that we used to
get because first get_property_ptr_ptr threw one and then
read_property throws the same exception again.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
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.

A dynamic property may be shadowed by a private/protected property.
Make sure we check property accessibility for non-indirect
properties as well.
Closes#3626.
If a property access would normally result in a magic method call,
but the property is subject to an active recursion guard, the
access should behave as if the magic method does not exist.
This commit fixes one instance where this was not the case -- we
should have been generating a property access error, but instead
the operation simply did not do anything.
