Found while working on #18879
gzread() and gzwrite() have effectively a 4GiB limit at the moment
because the APIs of the zlib library use unsigned ints.
For example, this means that the count argument of gzread() and gzwrite()
& co effectively are modulo 2**32.
Fix this by adding a loop to handle all bytes.
As for automated testing, I didn't find an easy way to write a phpt for
this that wouldn't use a lot of memory or requires a large file.
For instance, the gzread() test that I manually ran requires a 4MiB
input file (and I can't shrink it because zlib has a max window size).
Here are the testing instructions, run on 64-bit:
To test for gzwrite():
```php
$f = gzopen("out.txt.gz", "w");
gzwrite($f, str_repeat('a', 4*1024*1024*1024+64)); // 4GiB + 64 bytes
```
Then use `zcat out.txt.gz|wc -c` to check that all bytes were written
(should be 4294967360).
To test for gzread():
Create a file containing all a's for example that is 4GiB + 64 bytes.
Then compress it into out.txt.gz using the gzip command.
Then run:
```php
$f = gzopen("out.txt.gz", "r");
$str = gzread($f, 4*1024*1024*1024+64);
var_dump(strlen($str)); // 4294967360
var_dump(substr($str, -3)); // string (3) "aaa"
```
Closes GH-17775.
zlib_create_dictionary_string() allocates memory, so we can leak memory
if there's an early exit before the assignment to the return value.
Solve this by moving all validation upwards.
Closes GH-17788.
Because of the "H" modifier in ZPP, there are two bugs:
1) The stub is wrong and will cause a crash in debug mode.
2) Non-dynamic properties are not read correctly because they are not
DEINDIRECTed.
Closes GH-17750.
We must not `efree()` `zend_string`s, since they may have a refcount
greater than one, and may even be interned.
We also must not confuse `zend_string *` with `zend_string **`.
And we should play it safe by using `safe_emalloc()` to avoid
theoretical integer overflows.
We also simplify a bit, according to suggestions of @TimWolla.
Closes GH-16335.

When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
This enables the zlib library (https://zlib.net/) from a single place to
match the minimum required version across the php-src. This provides a
possible simpler version bump in the future. Macro's 2nd and 3rd
arguments can pass additional actions whether zlib library is found or
not for the possible future adjustments in the ext/standard where also
zlib might be required.
Support for pkg-config was introduced in 1.2.3.1.
The minimum zlib version has been bumped to 1.2.3.1
* Bump minimum zlib version to 1.2.11
This is aligned with CentOS 8, which has 1.2.11 in the default packages.
* [skip ci] Move zlib version change to UPGRADING
This matches the OpenSSL style version change notice already done in
this file.
