Problem summary

  • APAR NUMBER:  PJ40719
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  Open source C library
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    An OPR-4 (000004) system error might occur out of genops.c when
    opening or closing folders in a threaded environment.
    
    PACKAGE CONTENTS:
    Source Segments:
    None.
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    None.
    
    Support Files:
    None.
    
    OTHER BINARIES TO BUILD: YES
    (C) opensource/include/bits/libc-lock.h
    (C) opensource/glibc/obj/genops.o
    (C) opensource/stdlib/libCISO.so
    (C) opensource/stdload/CISO.so
    
    COMMENTS:
    The File Stream List in the CISO library (part of the I/O
    support for glibc) is not thread safe. When opening and closing
    new files in threads, corruption might occur in the File Stream
    List. The implementation of the File Stream processing, which
    makes locking calls, is located in genops.c.
    

Problem conclusion

  • SOLUTION:
    z/TPF pthread mutex lock and unlock calls were added to the
    libio macros, which are available for coding platform-specific
    locking APIs.
    
    COREQS: NO
    None.
    
    MIGRATION CONSIDERATIONS: NO
    None.
