This test is somewhat fragile in that it depends on how well a
particular regex is optimized. Apparently on 6.9.1 this regex
would hit the default retry_limit of 1000000 already. I'm limiting
this to 6.9.3 because that's the version that works for me.
This is very similar to the existing mbstring.regex_stack_limit,
but for backtracking. The default value matches pcre.backtrack_limit.
Only used on libonig >= 2.8.0.
mb_decode_numericentity() accepts a fourth optional parameter, which is
unused, however. Since this parameter doesn't do any harm, and to avoid
the small BC break, we're keeping this parameter for PHP 7, but adjust
the arginfo.
For PHP 8, we will remove this parameter.
Oniguruma is exclusively used by ext/mbstring, and only if mbregex is
enabled. Therefore it is unnecessary and confusing to have Oniguruma
related config stuff scattered elsewhere.
While we're at it, we also remove the referral to the bundled libonig
which is removed as of PHP 7.4.0, and the duplicated call to
`PHP_INSTALL_HEADERS()`.
Used in php-src the past and today removed and not used anymore:
- HAVE_CURL_EASY_STRERROR
- HAVE_CURL_MULTI_STRERROR
- HAVE_NEW_MIME2TEXT
- HAVE_MBSTR_CN
- HAVE_MBSTR_JA
- HAVE_MBSTR_KR
- HAVE_MBSTR_RU
- HAVE_MBSTR_TW
Part of oniguruma which doesn't use these anymore
- NOT_RUBY
- HAVE_STDARG_PROTOTYPES
Unused:
- HAVE_MPIR
Closes GH-4427
RFC: https://wiki.php.net/rfc/tostring_exceptions
And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
- All credits, license info preserved, only merged together to not have
to many places to edit.
- Changelogs integrated in the readme since they are not used anymore.
By introducing a hook that is called whenever one of
internal_encoding / input_encoding / output_encoding changes, so
that mbstring can adjust it's internal state.
This also makes internal_encoding work with zend multibyte.
Autoconf defines PACKAGE_* symbols:
- PACKAGE_NAME
- PACKAGE_VERSION
- PACKAGE_TARNAME
- PACKAGE_STRING
- PACKAGE_BUGREPORT
- PACKAGE_URL
and appends them to the generated config.h.in files. With AC_INIT change
via afd52f9d99 where package version, URL,
bug report location and similar meta data are defined, these
preprocessor macros are then non empty strings in the generated
configuration header file. When using phpize, PHP shares the config
files in extensions, warnings of redefined macros appear, such as:
- `warning: 'PACKAGE_NAME' macro redefined`
This patch now disables these non utilized symbols in the generated
config header files.
Better practice would be to include only API specific headers where
needed but this would require even more refactorings. Some extensions
such as pcre, pgsql, and pdo_pgsql solve this issue by undefining some
of these symbols before including the library configuration headers in
the code also. Because these symbols can be defined by any library which
uses Autotools.
Additionally, the unused PACKAGE_* symbols were cleaned for the bundled
libmbfl library and with this patch not needed undef code removed.
