* Remove ZEND_DVAL_TO_LVAL_CAST_OK
As far as I can see, this operation should always use the _slow method, and the results seem to be wrong when ZEND_DVAL_TO_LVAL_CAST_OK is enabled.
* update NEWS
Add zend_ini_parse_quantity() and deprecate zend_atol(), zend_atoi()
zend_atol() and zend_atoi() don't just do number parsing.
They also check for a 'K', 'M', or 'G' at the end of the string,
and multiply the parsed value out accordingly.
Unfortunately, they ignore any other non-numerics between the
numeric component and the last character in the string.
This means that numbers such as the following are both valid
and non-intuitive in their final output.
* "123KMG" is interpreted as "123G" -> 132070244352
* "123G " is interpreted as "123 " -> 123
* "123GB" is interpreted as "123B" -> 123
* "123 I like tacos." is also interpreted as "123." -> 123
Currently, in php-src these functions are used only for parsing ini values.
In this change we deprecate zend_atol(), zend_atoi(), and introduce a new
function with the same behavior, but with the ability to report invalid inputs
to the caller. The function's name also makes the behavior less unexpected:
zend_ini_parse_quantity().

Casting a huge unsigned value to signed is implementation-defined
behavior in C. By introducing the ZEND_THREEWAY_COMPARE() macro, we
can sidestep this integer overflow/underflow/casting problem.
Unfortunately, libedit is locale based and does not accept UTF-8
input when the C locale is used. This patch switches the default
locale to C.UTF-8 instead (if it is available). This makes libedit
work and I believe it shouldn't affect behavior of single-byte
locale-dependent functions that PHP otherwise uses.
Closes GH-7635.
zend_class_implements_interface works fine if the "class" is an
interface, so simply drop this assertion. This avoids the need to
special case this situation.
Add a family of upper case conversion functions to zend_operators.c,
by analogy with the lower case functions.
Move the single-character conversion macros to the header so that they
can be used as a locale-independent replacement for tolower() and
toupper().
Factor out the ugly bits of the SSE2 case conversion so that the four
functions that use it are easy to read and processor-independent.
Use the new ASCII upper case functions in ext/xml, ext/pdo_dblib and as
an optimization for strtoupper() when the locale is "C".
These are thin wrappers ... around the wrong functions. They call
the "_l()" version of the underlying APIs. For clarify, just call
the wrapped API directly.
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.
Trying to allocate a `zend_string` with a length only slighty smaller
than `SIZE_MAX` causes an integer overflow, so callers may need to
check that explicitly. To make that easy in a portable way, we
introduce `ZSTR_MAX_LEN`.
Closes GH-7294.
It's the same as (int) zend_atol() -- it doesn't try to do anything
integer size specific. Canonicalize to one function in preparation
for renaming zend_atol() to something less misleading.
FFI test is adjusted to use a zend_test function. It just calls
zend_atol() internally, but could really be anything.

We can't destroy the result operand early, because the division
might fail, in which case we need to preserve the original value.
Place the division result in a temporary zval, and only copy it
on success.
Fixes oss-fuzz #35876.
The result == op1 check did not work properly here, because op1
was &op1_copy at this point. Move the division by zero reporting
out of the _base function, so it can check the original op1.
Updates the deprecation message for implicit incompatible float to int conversion from:
```
Implicit conversion from non-compatible float %.*H to int in %s on line %d
```
to
```
Implicit conversion from float %.*H to int loses precision in %s on line %d
```

PDO implement half of this, but this functionality is generally
useful. Provide these as zend_u64_to_str and zend_i64_to_str to
complement zend_long_to_str.

Otherwise we may have inconsistent refcounts after OOM.
I expect this problem is much more prevalent, but this at least
fixes some string/array separation cases.
Fixes oss-fuzz #30999.
We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
This function is unused in php-src, and has somewhat dubious
semantics, especially since we switched convert_to_long to not
use strtol for the base 10 case.
If you want to convert strings from a different base, use
ZEND_STRTOL directly.
This function is unused, and also not particularly useful now that
PHP no longer prints doubles in a locale-sensitive way unless
someone really goes out of their way to force it.
