source: branches/ms-style/zoo-project/zoo-services/utils/status/service.c @ 830

Last change on this file since 830 was 788, checked in by knut, 8 years ago

Implemented support for PHP 7: The Zend API for PHP 7/PHPNG is substantially different from older versions. Therefore, an alternative implementation of zoo_php_support is provided in the new source file service_internal_php7.c. Presently the Zoo kernel can be built with support for either PHP 7 or older versions, see the makefiles (for Windows) nmake.opt and makefile.vc. Other makefiles have not been updated.

Fixed problem with ambiguous symbol in service_conf.y. Fixed problem with conversion of line endings yielding extra bytes in _getStatusFile on Windows platforms. Removed call to free() stack memory in zoo_service_loader.c. Fixed issue with size of structs in service.h.

  • Property svn:eol-style set to native
  • Property svn:mime-type set to text/x-csrc
