Subject [jira] Commented: (STDCXX-731) framework to verify binary compatibility
Date Tue, 22 Apr 2008 15:00:22 GMT


Martin Sebor commented on STDCXX-731:

One relatively easy, semi-automatic way of doing this would be to enhance the [{{buildntest}}|]
script to do two builds with two sets of sources, then swap the libraries, and rerun all examples
and tests. The results of those builds would then be processed by the [{{xbuildgen}}|]
script to produce a single cross-build report.

> In the 4.2.0 release we ran into binary incompatibilities late in the release cycle that
ended up costly to fix. What would have prevented the incompatibilities, or at least allowed
us to detect them early on, would have been an automated framework to verify the binary compatibility
of the library. This is a placeholder issue to design and implement such a framework.
