Looks to me like dcc_r_bulk_plain() is missing an msync(,,MS_SYNC). >From munmap man page:
The st_ctime and st_mtime field for a file mapped with PROT_WRITE and MAP_SHARED will be updated after a write to the mapped region, and before a subsequent msync() with the MS_SYNC or MS_ASYNC flag, if one occurs. And from msync man page: msync flushes changes made to the in-core copy of a file that was mapped into memory using mmap(2) back to disk. Without use of this call there is no guarantee that changes are written back before munmap(2) is called. To be more precise, the part of the file that corresponds to the memory area starting at start and having length length is updated. The flags argument may have the bits MS_ASYNC, MS_SYNC and MS_INVALIDATE set, but not both MS_ASYNC and MS_SYNC. MS_ASYNC specifies that an update be scheduled, but the call returns immediately. MS_SYNC asks for an update and waits for it to complete. /john __ distcc mailing list http://distcc.samba.org/ To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/distcc
