The recent fix for bug 52093 is not compatible with LibreSSL ≥ 2.7.0,
which we recognize as mostly OpenSSL 1.1.0 compatible, but they still
do not support `ASN1_INTEGER_set_int64()`.
Closes GH-7339.
With OpenSSL 3 ciphers may be registered, but not provided. Make
sure that openssl_get_cipher_methods() only returns provided
ciphers, so that "in_array openssl_get_cipher_methods" style
checks continue working as expected.
zend_double_to_str() converts a double to string in the way that
(string) would (using %.*H using precision).
smart_str_append_double() provides some more fine control over
the precision, and whether a zero fraction should be appeneded
for whole numbers.
A caveat here is that raw calls to zend_gcvt and going through
s*printf has slightly different behavior for the degenarate
precision=0 case. zend_gcvt will add a dummy E+0 in that case,
while s*printf convert this to precision=1 and will not. I'm
going with the s*printf behavior here, which is more common,
but does result in a minor change to the precision.phpt test.
This used to be necessary in the past because the NUM_BUF_SIZE
was set to 512, which is shorter than DOUBLE_MAX_LENGTH. Now the
value is either DOUBLE_MAX_LENGTH or larger (2048).
We don't guarantee any particular order, but this reduces test
failures under --preload that are sensitive to class order.
Add some ZEND_HASH_FOREACH_*_FROM macros to allow skipping the
persistent classes while iterating in forward direction.
It is very hard to determine in advance whether class linking will
fail due to missing dependencies in variance checks (#7314 attempts
this). This patch takes an alternative approach where we try to
perform inheritance on a copy of the class (zend_lazy_class_load)
and then restore the original class if inheritance fails. The fatal
error in that case is recorded and thrown as a warning later.
Closes GH-7319.
Dynamically declared classes categorically do not get linked during
preloading, even if all their dependencies are known. The warning
is misleading in this case, and there isn't anything the user can
do to address it.
This functionality is not used productively in PHP and it's not used in
any of the extensions to my knowledge. Since it looks like this functionality
isn't required by anyone, let's clean up mysqlnd and drop it.
Combine the code for checking whether all dependencies are
available and reporting an error if they are not. Actually store
the loaded deps and then use those when checking for type
availability, instead of looking up the same classes again and
again.
Currently, classes that can't be linked get moved back into the original script
and are not preloaded. As such classes may be referenced from functions that
did get preloaded, there is a preload autoload mechanism to load them at
runtime.
Since PHP 8.1, we can safely preload unlinked classes, which will then go
through usual lazy loading. This means that we no longer need the preload
autoload mechanism. However, we need to be careful not to modify any hash
table buckets in-place, and should create new buckets for lazy loaded classes.
