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.

/*
|
|
* Basic Windows implementation for the nice() function.
|
|
*
|
|
* This implementation uses SetPriorityClass() as a backend for defining
|
|
* a process priority.
|
|
*
|
|
* The following values of inc, defines the value sent to SetPriorityClass():
|
|
*
|
|
* +-----------------------+-----------------------------+
|
|
* | Expression | Priority type |
|
|
* +-----------------------+-----------------------------+
|
|
* | priority < -9 | HIGH_PRIORITY_CLASS |
|
|
* +-----------------------+-----------------------------+
|
|
* | priority < -4 | ABOVE_NORMAL_PRIORITY_CLASS |
|
|
* +-----------------------+-----------------------------+
|
|
* | priority > 4 | BELOW_NORMAL_PRIORITY_CLASS |
|
|
* +-----------------------+-----------------------------+
|
|
* | priority > 9 | IDLE_PRIORITY_CLASS |
|
|
* +-----------------------+-----------------------------+
|
|
*
|
|
* If a value is between -4 and 4 (inclusive), then the priority will be set
|
|
* to NORMAL_PRIORITY_CLASS.
|
|
*
|
|
* These values tries to mimic that of the UNIX version of nice().
|
|
*
|
|
* This is applied to the main process, not per thread, although this could
|
|
* be implemented using SetThreadPriority() at one point.
|
|
*
|
|
* Note, the following priority classes are left out with intention:
|
|
*
|
|
* . REALTIME_PRIORITY_CLASS
|
|
* Realtime priority class requires special system permissions to set, and
|
|
* can be dangerous in certain cases.
|
|
*
|
|
* . PROCESS_MODE_BACKGROUND_BEGIN
|
|
* . PROCESS_MODE_BACKGROUND_END
|
|
* Process mode is not covered because it can easily forgotten to be changed
|
|
* back and can cause unforseen side effects that is hard to debug. Besides
|
|
* that, these do generally not really fit into making a Windows somewhat
|
|
* compatible nice() function.
