[Bug libfortran/31052] New: Bad IOSTAT values when readings NAMELISTs past EOF

[anlauf at gmx dot de]

Hi,

the attached problem showed up after PR 30918 got fixed.
(Thanks, Jerry!)
When reading a namelist again and again, even after EOF,
then suddenly the IOSTAT values jumps from -1 to 5008.
This does not happen with other compilers.

The namelist file fort.10 is the same as in PR 30918.

Output of test run:


NAMELIST /REPORT/ after iteration 1:
&REPORT
 TYPE=SYNOP       ,
 USE=active      ,
 MAX_PROC=         20,  /

 Number of reports:           1
 Last status =          -1
 Number of reports:           0
 Last status =          -1
 Number of reports:           0
 Last status =        5008

Cheers,
-ha

The value 5008 is listed in libgfortran.h as ERROR_ENDFILE.  The
-1 corresponds to ERROR_END.  So, the return value of 5008 is 
telling you that you are trying to (initiate a?) read beyond
the end of the file, which you admit to doing.

AFAIK, the IOSTAT values aren't documented in gfortran.texi.
Someday, someone will get around to documenting them.

I actually do not want to read beyond the end of file,
I want gfortran to stay at the end of the file when trying to
read the next record or namelist.

All other compilers I have checked (xlf, ifort 7.x-9.x, g95)
stay at the end of file.  I find their behavior consistent
with the F2003 standard, section 9.10.4:

Execution of an input/output statement containing the IOSTAT=
specifier causes the scalar-int-variable in the IOSTAT= specifier
to become defined with

(3) The processor-dependent negative integer value of the constant
    IOSTAT_END (13.8.2.5) if an end-of-file condition occurs and no
    error condition occurs, or (...)

> AFAIK, the IOSTAT values aren't documented in gfortran.texi.
> Someday, someone will get around to documenting them.

The standard separates end-of-file, end-of-record, and
error conditions.  I don't think that EOF is necessarily
an error condition.  It would be nice if gfortran would
conform with these other compilers.

I stand corrected with regard to xlf.  It returns a
documented "recoverable error" condition.

I have to find out why the code in question that lead to
the problem report does not properly recover with gfortran.

It might be an interference with BACKSPACE, as the
full code that lead me to the investigation does a
scan through a namelist file and uses BACKSPACE
here and then.

Removing the BACKSPACE on the unit when the EOF condition
occured helps somewhat, but then I encounter a funny
error on a NAMELIST read:

Fortran runtime error: Missing format for FORMATTED data transfer

I thought that NAMELIST reads are list-directed.
Anyway, I guess I have to produce a better testcase.

For whatever reason, you are hitting (2).

(2) A processor-dependent positive integer value if an error condition
    occurs.

At a guess, you get a -1 if you start a read from within the
the file, and you hit the EOF.  Once the EOF is hit, the file
is probably positioned at a point beyond the EOF, the next
attempt of a read is considered an error condition, so the
5008 is return.

I saw your other email about BACKSPACE.  I don't know what the
expected behavior is with BACKSPACE and a file position that is
at or exceeds the EOF marker.  At a guess and knowing the vagueness
of the Standard, this is probably processor-dependent.  I think
you're getting hit by 9.10.2(4) for F2003:

(4) If the file specified in the input statement is an external
    record file, it is positioned after the endfile record.

and BACKSPACE isn't doing its job with respect to Note 9.54.

This is an area that Jerry knows.  Perhaps, he has an opinion.

Revised demo.  New namelist for this demo follows.

At some place, the input read gets garbled with gfortran,
see the comment before the print statement in "position_nml".
Removing a few lines in the main program will hide this bug.
Somehow the cycle REWIND/READ/BACKSPACE/(READ) confuses the runtime.

(In reply to comment #8)

In the new example, when I comment out the BACKSPACE
in "position_nml" for ios<0 (EOF condition), the garbled
output goes away.  But in the large program (where this
was extracted) this does not help; it dies later.
(See comment #5).

------- Comment #10 from jvdelisle at gcc dot gnu dot org  2007-03-07 03:37 -------
Replying to comment #6.  I am forming an opinion. Section 9.7 of the F2003
standard states:

  "Backspacing over records written using list-directed or namelist formatting
is prohibited."

This implies to me that one should not mix BACKSPACE with a namelist file. 
However, I want to study the demo program a bit.  This might be one of those
"correct behavior, outside the standard" problems.

Generally, reading past the last record gives an EOF and trying to read again
is an error. The concept of a "record" with a namelist file does not seem to be
compatible to me though.

I will respond further after I have a chance to explore this a bit more.

------- Comment #12 from jvdelisle at gcc dot gnu dot org  2007-03-07 04:45 -------
The garbled text is because gfortran does not default initialize variable as
some compilers do.  The 'line' variable is not getting read because gfortran is
getting an error on the read, so the it is not set to anything.  Put a: line=""
at the top of the subroutine to get around that.

After this you can see that IOS is set to -1, so 'line' is not read.

I am now going to study the REWIND and BACKSPACE and see what we should be
doing differently if anything.

------- Comment #13 from jvdelisle at gcc dot gnu dot org  2007-03-07 06:40 -------
AFAICT A backspace is not allowed for namelist files according to 9.7.1

I interpret this to mean this is invalid code.

Further, Note 9.54 states that if the preceding record read is the EOF record,
the BACKSPACE would position the file to "before" the EOF.  You can think of
this as in between the last record and the EOF record.  So subsequent reads
will again read the EOF record.  From the demo program, you can see the
repeated values of ios=-1, or the EOF condition returned by gfortran.  So I
believe the gfortran behavior is correct.

Regardless, I do think REWIND should clear the EOF condition for namelist and I
don't think it is.  I confirm this as a bug.

I am working on it.

Jerry,

I tried FX's snapshot from today (20070319) and the example
above works.  A somewhat more twisted example which I have
not yet been able to reduce leads to an IOSTAT value of 5001
(BTW: what does that value mean?) in the namelist read, although
the subroutine position_nml succeeds.

The file libgfortran is not in that distribution.  Could you
please put here these IOSTAT values?  Nor are these in the

Error 5001 would be ERROR_OPTION_CONFLICT.  There are 18 different errors
associated with that code.  To find out which one, you must remove the iostat
from the offending line so that gfortran will print the error message for you.

Another option is to use iomsg and get the string.

You can access the code base at gcc.gnu.org/viewcvs or better, download with
anonymous svn.  See instructions here: http://gcc.gnu.org/svn.html.  If you do
the svn approach, its very simple to get latest update and you are a few
keystrokes from building it yourself. :)

Thanks, I did not know this F2003 feature.  In that case I get for

          iomsg = ""
          read (nnml, nml=THINNING, iostat=ios, iomsg=iomsg)

the following output:

 iostat =        5001
 iomsg  = Missing format for FORMATTED data transfer                            

No crash, of course, at least in the read statement.

Untested patch to fix regression on sixtrack

This patch reverts portions of the original patch and keeps a minimal set of
changes to see if this clears the regression.  The patch is against current
trunk.  If you could please test, I would appreciate.

Regression tested on x86-64-Gnu/Linux

I do not have a testcase here yet. If this fails, then I will try a further
reduction.

Jerry,

with the latest variant of your patch I get a failing namelist read
with the new reduced testcase gfcbug61a.f90 (uses gfcbug61a.nml).

If I remove one of the entries in the namelist file,
the second read succeeds.  There must still be a problem with
REWIND/BACKSPACE/READ.

I will keep at it on this.  It seems we have a conflict between the SPEC 
test that was failing and the namelist testcases.  Unfortunately I don't 
have the SPEC test case to see to try to weed this out.

What I will do is work on the patch i had before and send it to folks to 
  test the SPEC portion.  That may take a while, so please be patient.

Sorry for the troubles.

Jerry,

I hate to bother you, but it is not really fixed.

Add a comment line at the end of the namelist file gfcbug61a.nml,
so that it reads:

&REPORT type='report1' /
&REPORT type='report2' /
!

Now the last attempt to read this namelist fails again.

Sorry, reopening this one...

Jerry,

thanks so far, but now I am back to the situation described
in comment #23.  I will try to produce a new reduced testcase
that leads to this crash in the next days.  I'd like to ask you
to keep this PR open for a few more days until we know whether
the other problem is related or unrelated to this PR.

Now I am confused because I reverted and re-patched and it was tested by spark

[Bug libfortran/31052] [4.2 only] Bad IOSTAT values when readings NAMELISTs past EOF

[jvdelisle at gcc dot gnu dot org]

------- Comment #51 from jvdelisle at gcc dot gnu dot org  2007-05-20 23:50 -------
Two testcases for 4.3 pass on 4.2.  Fixed on 4.3.  Because of the problems with
regressions on SPEC, I would rather not backport this.  Closing.

Herald, if something else comes up, please file a new report.  This one is too
long.
