Bug report (12=17020 TC029) SAMBA 2.2.8 release 20040908 - intermittent content loss

[RR - Rod Regier]

(n.b. a shorter version of this was reported to JYC in August,
      but he was unable to reproduce the failures).

Summary: Some intermittent file corruption is occuring.
         We would like to provide a good test case, but such eludes us.
         Since corruption is serious, we thought the list subscribers
         should be alerted to watch for same.

       - Problem: NTTS (Windows) perl program, run across the network on
         files on the OpenVMS system, is reading a line incorrectly.
         Problem does not persist if the file in question is copied
         to a local drive.
         - Line in question appears to have been replaced with the last
line
           of a file read previously in the same perl session.
         - Test file in question is rl_libw:dbtdsp.cpp
         - Program is %dyulib%\cxxpre.prl
         - Diff is:
        ************
        File DSA0:[TH]DBTDSP.TMP;1
          177                   SPLSTR_OPTIONAL_PORTION_RIGHT   = 1
          178      remark_lines_displayed=0;
        ******
        File DSA0:[TH]DBTDSP2.TMP;1
          177      remarks_attached=FALSE;
          178      remark_lines_displayed=0;
        ************
        - the SPLSTR line is from rl:splstr.inc, note that the line
          that should have been read is missing.
        - This is the only difference in all files read in that perl
          session.
          - testing was done to output each line as each file was read
            to a debug log, logs were then diffed.
        - The line in question is also correctly read where originally
          processed (in splstr.inc).
        - A simple test case (read in and print out only the 2 files
          in question, with no transformations) does not produce the
          problem.
        - TH    > Problem encountered again in another file,
              rl_libw:invok.hpp:
              - Following is the difference in what perl sees on both
                systems:
                ************
                File
SYS$SYSDEVICE:[DYMAX.WIP.RL.LIB.SRC.CPP.TRN]INVOK_TEST.2DW`
                  116   typedef void (*invokr_word_nowninfo_type) (const
word&,
                  117      owncode_info_type&);
                ******
                File SYS$SYSDEVICE:[TH]INVOK_TEST.2DW;1
                  116   typedef void (*invok
                  117      owncode_info_type&);
                ************
          - Again the error occurs right at the point where the line
            is read.
          - Changing the files included inside invok.hpp (in an attempt
            to produce a minimum test case) changed the location
            of the partial line error (a different line was truncated),
            or caused the partial line error to disappear entirely.
          - In all cases to date the error has only occurred when
            multiple files are read over the network by a single
            program in a single session.
       - TH     > FYI I encountered an odd problem of this sort today
                  (20-Sep-2004)
         in Araxis Merge, so it is not just isolated to perl.
         - a display of fdutil.pl vs .new showed the following
           artifacts in the .new
           - Missing last line
           - A line from the header (!!!======) duplicated further
             down in the code, at the end of an unrelated line.  This
             appears to have been a copy, since the header itself
             was intact.
