Report 1134 Actions Problem Report Number 1134 Submitter's Classification Test Suite problem State Resolved Resolution Rejected (REJ) Problem Resolution ID REJ.X.0336 Raised 1970-01-01 08:00 Updated 2003-03-13 08:00 Published null Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98) Certification Program The Open Brand certification program Test Suite VSU version 5.0.2 Test Identification CAPIbase/flockf 42,43,44 Problem Summary PG4U.00136 This request claims that the test may fail on systems where errno is defined as a macro. Problem Text On our implementation, the following tests fail to build in UNIX 98 mode: CAPIbase/flockf/flockf42 CAPIbase/flockf/flockf43 CAPIbase/flockf/flockf44 CAPIbase/flstat/flstat33 CAPIbase/fmmap/fmmap41 CAPIbase/freadv/freadv70 CAPIbase/freadv/freadv71 CAPIbase/freadv/freadv72 CAPIbase/fwritev/fwritev75 CAPIbase/fwritev/fwritev76 CAPIbase/fwritev/fwritev77 CAPIbase/fftruncate/fftruncate18 All fail with the exact failure noted in the test results section. The problem is that these tests have private headers with a structure similar to the following defined: /* ** Structure returned by the execed programs */ struct lfstatus { int status; char reason[512]; int value; int errno; }; This structure conflicts with our per-thread errno implementation. When _XOPEN_SOURCE is set to 500, we turn on our POSIX Threads implementation which in turn sets the following in our errno.h header: extern int *___errno(); #define errno (*(___errno())) Therefore, the build of the test fails because the errno member of the lfstatus structure gets expanded to the __errno() function in our implementation. Every occurrence of attempting to access the lfstatus structure errno member then results in each of the syntax errors. The test suite is relying on undefined implementation behavior. In section 4.1.3 of the ANSI standard, the following statements are made with respect to errno: The header <errno.h> defines several macros, all relating to the reporting of error conditions. The macros are... errno which expands to a modifiable lvalue that has type int... It is unspecified whether errno is a macro or an identifier declared with external linkage. If a macro definition is suppressed in order to access an actual object, or a program defines an identifier with the name errno, the behavior is undefined. This last sentence is key. Also note, that a footnote for this states that the "macro errno need not be the identifier of an object. It might expand to a modifiable lvalue resulting from a function call (for example *errno())." See also the POSIX Realtime specification, IEEE Std 1003.1-1996, sections 2.4, which references the ANSI standard, and B2.4 for per-thread errno rationale. A SR request was submitted to the test suite developers Reference (VSU SR #620) resulting in the following response: Following approval by The Open Group, which we will recommend, this will be fixed in the next release. Pending an update to the test suite, we would like to request a TSD be granted for these failures.
