Bug #65948 [Com]: extension and PHP API version mismatch

Edit report at https://bugs.php.net/bug.php?id=65948&edit=1 ID: 65948 Comment by: wzis at hotmail dot com Reported by: wzis at hotmail dot com Summary: extension and PHP API version mismatch Status: Wont fix Type: Bug Package: *General Issues Operating System: Linux PHP Version: Irrelevant Block user comment: N Private report: N New Comment: But API should be very stable: one example is glibc: even though it has been many version releases, but so long you compile a program on a version of glibc, and only run that binary on system with that version of glibc or newer, the program can run successfully. Previous Comments: ------------------------------------------------------------------------ [2013-10-23 23:12:09] johannes@php.net If you want to do experiments in that area you could do magic by creating your own get_module() function which detects the PHP version, but we change structures as we see need between releases. You are mentioning 5.1 versus 5.5 that's 8 years of development work with lots of improvements. We care a lot about binary compatibility between bug fix releases (x.y.z++) but not feature releases (x.y++.z) ------------------------------------------------------------------------ [2013-10-23 23:00:34] wzis at hotmail dot com If we only use very minimum PHP API functions and data structures, is there a way to achieve build once, run on multiple versions? ------------------------------------------------------------------------ [2013-10-23 22:56:13] wzis at hotmail dot com What do you mean by "Please use #if #ifdef to make your module built with versions. I personally have module that works from PHP 4.3 through master, you should be able to do that." Do we still need to build the module for each version (x.y) or by using the #if #ifdef now we can build module on one version, use it on newer versions? Any example? ------------------------------------------------------------------------ [2013-10-23 01:39:34] yohgaki@php.net We only keep API compatibility for "minor" version. That's the way it is. Please use #if #ifdef to make your module built with versions. I personally have module that works from PHP 4.3 through master, you should be able to do that. ------------------------------------------------------------------------ [2013-10-23 01:05:31] johannes@php.net We keep binary compatibility for all z in x.y.z version numbers. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
