Martin Sebor commented on STDCXX-683: ------------------------------------- Requirements on Markups 1. Location. The markups must be in the form of human-readable and editable text stored in a location that can be easily and intuitively associated with each component (currently, example, locale, or test). One obvious location is the source code for each component itself. There, the markups could take the form of comments that could be easily found by the test harness. Another convenient location is a separate file with the same base name but a different suffix than the component itself. Yet another possibility is storing all markups in a single text file and with the name of the component as the key. The implementation should be such so as to make it easy to switch from one location to the next if it turns out to be convenient. 2. Format. The format of the markups must be easy to read and write and make it possible to easily express precise constraints involving the operating system and its version, the compiler and its version, the library configuration, and the expected status. It must be possible to set more than one constraint for each component, and it must be possible for a single constraint to refer to more than one platform or configuration. One possible format is to use relational operators and boolean logic. For example, to refer to XLC++ 7.0.0.9 on AIX 5.3 and prior, the expression might look something like this: os==AIX && (os_major<5 || os_major==5 && os_minor<=3) && compiler==XLC && compiler_major==7 && compiler_minor==0 && compiler_micro==0 && compiler_patch==9. Another possible format is to adopt a conveniton similar to the GNU cpu-vendor-os triple produced by config.guess (an example of such a triple is i386-redhat-linux or sparc-sun-solaris2.9). In our case, the GNU convention would need to be modified and extended to include the compiler and the library configuration and might look something like this: cpu-vendor-os-compiler-configuration. We could then use shell globbing to implement matching. For example, the following two patterns would have to be used at the same time in order to refer to a 15D configuration of the library build with XLC++ 7.0.0.9 on AIX 5.3 and prior: *-ibm-aix5.[0-3]-xlc7.0.0.9-15D *-ibm-aix[1-4].*-xlc7.0.0.9-15D The leading asterisk indicates no preference for the CPU component. > implement notion of expected failures in the test suite > ------------------------------------------------------- > > Key: STDCXX-683 > URL: https://issues.apache.org/jira/browse/STDCXX-683 > Project: C++ Standard Library > Issue Type: New Feature > Components: Test Driver, Tests > Affects Versions: 4.2.0 > Reporter: Martin Sebor > Assignee: Martin Sebor > Priority: Critical > Attachments: codes.html, xcodes.html > > > Tests (or examples) that fail for known reasons that we haven't been able to > deal with should be distinguished from failures that haven't been analyzed > yet.
