* Simplify libxmlrpc bundling and buildingPeter Kokot2019-04-233-28/+0
| | | | | | | | | | | | | | | | | | | The xmlrpc library is a forked, modified and bundled into the PHP source code. Instead of having a separate *nix build system files in the xmlrpc library this patch removes unneeded build checks. - AC_PROG_CC is not needed to be called by the extension itself since it is already part of the main configure.ac and the phpize's configure.ac. - UNDEF_THREADS_HACK is not used in the current codebase. - Symbols defined by XMLRPC_HEADER_CHECKS are not used in the current code. - Symbols defined by XMLRPC_FUNCTION_CHECKS are not used in the current code. - AC_PROG_RANLIB is already done by the TSRM's files and isn't needed for the xmlrpc extension to work. - AC_PROG_LN_S is already done by the PHP main configure.ac and also isn't needed by the xmlrpc extension to be built.

* Sync AC_CHECK_SIZEOF m4 macro callsPeter Kokot2019-03-182-11/+0
| | | | | | | | | | | | | | | | - AC_CHECK_SIZEOF is now called mostly only in PHP_CHECK_STDINT_TYPES() macro except for some parts checking for the 32 or 64 bit architecture. - SIZEOF_CHAR removed since it is always 1 - ZEND_BIN_ID is now of a more logical pattern `BIN_48888` on 64bit architectures and `BIN_44444` on 32bit instead of literal string `BIN_SIZEOF_CHAR48888` on 64bit and `BIN_SIZEOF_CHAR44444` on 32bit. The unneeded SIZEOF_CHAR part has been removed. - XMLRPC_TYPE_CHECKS removed - The `long long int` is the same as `long long` and redundant checks removed accordingly. - Removed PHP_CHECK_64BIT macro. Checking if current platform is 64bit or not can be also done simply by using a check of the long type on place. This removes redundant m4 macro PHP_CHECK_64BIT.
* Clean build systemPeter Kokot2019-03-141-9/+1
| | | | | | | | | | | | | | | | Changes: - AC_TYPE_SIZE_T called on only one place (configure.ac) - AC_FUNC_ALLOCA called on only one place (configure.ac) - AC_TYPE_UID_T called on only one place (configure.ac) - HAVE_STRSTR removed since strstr is part of C89 standard [1] - Remove checks for strtol and strpbrk - Checking for the presence of perror function is not needed anymore since it is part of C89 standard and PHP calls it unconditionally. - Checking for functions strdup, setenv, strerror, and memmove done only on one place (configure.ac) - outdated check for snprintf removed 1: https://port70.net/~nsz/c/c89/c89-draft.html

* Add AS_HELP_STRING to *nix build configure optionsPeter Kokot2019-03-071-9/+23
| | | | | | | | The Autoconf's default AS_HELP_STRING macro can properly format help strings [1] so watching out if columns are aligned manually is not anymore. [1] https://www.gnu.org/software/autoconf/manual/autoconf.html#Pretty-Help-Strings
* Remove obsolescent AC_HEADER_STDC and memcpy checkPeter Kokot2019-03-011-2/+1
| | | | | | | | | | | | | | | | | | | | | Autoconf 2.59d (released in 2006) [1] started promoting several macros as not relevant for newer systems anymore, including the `AC_HEADER_STDC`. This macro checks if given system has C89 compliant header files such as `<string.h>`, `<stdlib.h>`, `<stdarg.h>`, `<float.h>`,... and defines the `STDC_HEADERS` symbol [2]. Case is that current systems should be well supported with at least C89 standard headers [3]. Given headers are still additionally checked with the `AC_PROG_CC` macro, yet not needed anyway. Additionally, the HAVE_MEMCPY check has been removed. The memcpy function is standardized by C89 and later.

* Remove local variablesPeter Kokot2019-02-032-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we allow ext/xmlrpc to be built against a system libxmlrpc(-epi), we must not `efree` memory which has been allocated via `malloc`. To distinguish bundled and system libxmlrpc(-epi) we introduce the macro `HAVE_XMLRPC_BUNDLED` (analogous to how it is done by ext/gd). We deliberately keep the ugly `#ifdef`s, instead of tucking them away in an `XMLRPC_FREE()` macro, to not forget that it is a bad idea to fork and bundle a library, but to also allow building against an unpatched system lib.

This macro checks if both `<sys/time.h>` and `<time.h>` can be included at the same time and defines the `TIME_WITH_SYS_TIME` and `HAVE_SYS_TIME_H` symbols. On current system such check is not relevant anymore because in case both headers are present both can be also included at the same time. This patch simplifies this checking.

* | | | Remove AC_C_CONSTPeter Kokot2018-09-021-1/+0
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Autoconf 2.59d (released in 2006) [1] started promoting several macros as not relevant for newer systems, including the `AC_C_CONST`. The `const` keyword is used in C since C89. On old systems some compilers lacked the `const` and this macro defined it to be empty. This check was relevant on systems with compilers before C89 and on current systems it can be omitted. [2] PHP also requires at least C89 so `const` is always available.
