* Remove HAVE_STRCOLL checkPeter Kokot2019-06-281-2/+0
| | | | | | | | | The strcoll function is defined in the C89 standard and should be on today's systems always available via the <string.h> header. https://port70.net/~nsz/c/c89/c89-draft.html#4.11.4.3 - Remove also SKIPIF strcoll check in test
* Disable float division by zero sanitizer for div_functionNikita Popov2019-06-201-0/+3
| | | | | We intentionally divide by zero here and want to get IEEE-754 semantics.

* Avoid overflow UB in is_numeric_stringNikita Popov2019-06-191-2/+2
| | | | | We intentionally overflow the signed space here, so make this an unsigned variable and only cast to signed at the end.
* Support full variance if autoloading is usedNikita Popov2019-06-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep track of delayed variance obligations and check them after linking a class is otherwise finished. Obligations may either be unresolved method compatibility (because the necessecary classes aren't available yet) or open parent/interface dependencies. The latter occur because we allow the use of not fully linked classes as parents/interfaces now. An important aspect of the implementation is we do not require classes involved in variance checks to be fully linked in order for the class to be fully linked. Because the involved types do have to exist in the class table (as partially linked classes) and we do check these for correct variance, we have the guarantee that either those classes will successfully link lateron or generate an error, but there is no way to actually use them until that point and as such no possibility of violating the variance contract. This is important because it ensures that a class declaration always either errors or will produce an immediately usable class afterwards -- there are no cases where the finalization of the class declaration has to be delayed until a later time, as earlier variants of this patch did. Because variance checks deal with classes in various stages of linking, we need to use a special instanceof implementation that supports this, and also introduce finer-grained flags that tell us which parts have been linked already and which haven't. Class autoloading for variance checks is delayed into a separate stage after the class is otherwise linked and before delayed variance obligations are processed. This separation is needed to handle cases like A extends B extends C, where B is the autoload root, but C is required to check variance. This could end up loading C while the class structure of B is in an inconsistent state.

* Implement basic variance supportNikita Popov2019-05-241-2/+2
| | | | | | | This is a minimal variance implementation: It does not support any cyclic type dependencies. Additionally the preloading requirements are much more restrictive than necessary. Hopefully we can relax these in the future.

* Remove local variablesPeter Kokot2019-02-031-10/+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.

* | | Remove unused Git attributes identPeter Kokot2018-07-251-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The $Id$ keywords were used in Subversion where they can be substituted with filename, last revision number change, last changed date, and last user who changed it. In Git this functionality is different and can be done with Git attribute ident. These need to be defined manually for each file in the .gitattributes file and are afterwards replaced with 40-character hexadecimal blob object name which is based only on the particular file contents. This patch simplifies handling of $Id$ keywords by removing them since they are not used anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | convert_scalar_to_number() will now call cast_object() with an _IS_NUMBER argument, in which case the cast handler should return either an integer or floating point number, whichever is more appropriate.
