Furthermore, say I'm using Weston 1.3.91... a usage of WESTON_VERSION_COMPATIBLE_WITH(1,3,0) would return True (1), which is wrong since the API/ABI actually changed somewhere between 1.3.90 and 1.3.91.
Granted, most API/ABI consumers won't be using x.y.9z development version series. But, as it's written now, they would be forced to add an extra check for every major/minor release if they are supporting more than one API/ABI. Our usage model, however, is for the wayland-fits test suite where it needs to support unstable (development versions) and stable API/ABI in a continuous integration environment. Regardless, the macro logic needs to change so that it appropriately reflects the macro name. > -----Original Message----- > From: wayland-devel-boun...@lists.freedesktop.org > [mailto:wayland-devel-boun...@lists.freedesktop.org] On Behalf Of Eoff, > Ullysses A > Sent: Friday, January 24, 2014 1:05 PM > To: Daniel Stone > Cc: wayland-devel@lists.freedesktop.org > Subject: RE: [PATCH 1/2 v2] version: Fix WESTON_VERSION_AT_LEAST macro > > Even with just a rename, if the API/ABI doesn't change from 1.4.x to 1.5.x > the macro wouldn't work if you used WESTON_VERSION_COMPATIBLE_WITH(1,4,0) > when version == 1.5.0 as it's written now. > > That is, with a rename, the logic indicates that "No major or minor > release is compatible with another major or minor release", regardless of > API/ABI changes. > > > -----Original Message----- > > From: Daniel Stone [mailto:dan...@fooishbar.org] > > Sent: Friday, January 24, 2014 12:37 PM > > To: Eoff, Ullysses A > > Cc: wayland-devel@lists.freedesktop.org > > Subject: Re: [PATCH 1/2 v2] version: Fix WESTON_VERSION_AT_LEAST macro > > > > Hi, > > The macro should really be called WESTON_VERSION_COMPATIBLE_WITH() - > > it's done that way specifically to allow breaking API/ABI at least > > every minor release. > > > > Cheers, > > Daniel > > > > On 24 January 2014 19:11, U.
