[PATCH] Fixes testsuit/gdb.base/annota1.exp

[PATCH] Fixes testsuit/gdb.base/annota1.exp

[Paul Gilliam]

ping!

This patch fixes a problem in annota1.exp

First message in annota1.exp thread:
http://sources.redhat.com/ml/gdb-patches/2004-09/msg00349.html

Last message in  in annota1.exp thread:
http://sources.redhat.com/ml/gdb-patches/2004-09/msg00374.htm

The annota1.exp patch was put on hold, waiting for a set backtrace patch.

I submitted a set backtrace patch here:

First message in set backtrace thread:
http://sources.redhat.com/ml/gdb-patches/2004-10/msg00261.html

last message in set backtrace thread:
http://sources.redhat.com/ml/gdb-patches/2004-10/msg00443.html

Then, like everyone else, I got involved in other things.  But an internal bug system just reminded me these where still pending.

Where do these patches sit now?

There are too many assorted attachments in those threads, some of which
are outdated.  Could you repost, or at least post links to, any patch
that you specifically want reviewed?

[PATCH] add new .exp file and a 'c' testfile to test backtrace limits etc.

[Paul Gilliam]

[-- Attachment #1: Type: text/plain, Size: 918 bytes --]

OK.  this is in partial responce to:
	http://sourceware.org/ml/gdb-patches/2005-04/msg00145.html

This patch adds a new test file, setbacktrace.exp along with a new 'c' test program,
setbacktrace.c.

The purpose of this new test is to check backtrace releated features not tested
elsewhere in the testsuit:
   *  Check that we know what backtrace options are available.
   *  Check that GDB will only backtrace the requested number of frames.
   *  Check that GDB doesn't backtrace past main unless asked to do so.

One problem:  I don't know how to add new files in a patch.  So I have attached the files
and include only the ChangeLog entry here in the body of this e-mail.

-=# Paul #=-

2005-04-15   Paul Gililam  <pgilliam@us.ibm.com>

	* gdb.base/setbacktrace.exp (new file): Check backtrace releated
        features not tested elsewhere.
        * gdb.base/setbacktrace.c (new file): Test case used by above.

[Daniel Jacobowitz]

This test is going to need a little work still.  Thanks for starting
it.

You diff it against /dev/null; either by hand or by adding a dummy line
to CVS/Entries.  There's also "cvsdo add" in the cvsutils package,
which automates that.

I'm pretty sure this isn't necessary any more.

This is very permissive.  Do you really need to allow so much?  This
will accept garbage at the end of lines.  Otherwise the pattern
construction is very nice.

Please don't use gdb_suppress_tests.

Did you test this testcase? :-)  There's "set backtrace past-entry"
now.  Also, same comment about ${leadin}.

I don't think this does what you want it to do.  It won't ignore any
extra, and it won't ignore garbage between frames.  You probably want
to construct a single regular expression using string concatenation
rather than list append.

That's a general comment, it applies to all the uses of
gdb_expect_list.

It would be better to use gdb_test_multiple and explicitly match the
KFAIL.  And to document what the problem is.

Wrap long lines where it's easy to do, please.  It's not worth the
trouble for most TCL, but comments are easy.

I'm not sure how portable this is... especially since you're requiring
there be at least one GDB-detectable frame past main.

I sent you some comments on this patch in April.  Here's another one
that may be useful:
  http://sourceware.org/ml/gdb-patches/2005-05/msg00590.html

This patch fixed the bug I originally wanted this test case to test
for, and a couple of related bugs.  If you don't have time, let me
know, and I'll try to update the test myself.

[PATCH] Fixes testsuit/gdb.base/annota1.exp to deal with 'Breakpoint address adjusted'

[Paul Gilliam]

OK.  this is in partial responce to:
        http://sourceware.org/ml/gdb-patches/2005-04/msg00145.html

There were two problems with gdb.base/annota1.exp.  This patch is only for the first one.

The problem here is that, in some architectures, a breakpoints in a shared object will be
adjusted once the shared object is loaded.  This cause two messages not accounted
for by gdb.base/annota1.exp:
	Breakpoint address adjusted from ....
	Breakpoint <n> address previously adjusted from ...

[PATCH] Fixes testsuit/gdb.base/annota1.exp

[Paul Gilliam]

OK.  this is in partial responce to:
        http://sourceware.org/ml/gdb-patches/2005-04/msg00145.html

There were two problems with gdb.base/annota1.exp.  This patch is only for the second one.

The problem here is that a bug in backtrace was causing a false nagitive in gdb.base/annota1.exp,
so the feature being tested was OK, but was being failed due to some other bug that caused the
backtrace to not stop at the end.

NOTE: this also allows for 'doc symbols' like '.printf'.  I understand that these are going away
soon, but an extra '\.?' shouldn't hurt anything.

I would strongly prefer not to include this one.  This isn't a unit
testsuite; all GDB tests cover multiple features.  Some backtrace bugs
only show up in these testcases, because they're so picky.

You didn't mention when resubmitting these patches that there were
objections to them.  That's kind of important.  I see that Andrew had
the same objection that I do.

OK, I understand.

I withdraw this patch.

[PATCH] Fixes testsuit/gdb.base/annota1.exp

[Paul Gilliam]

[-- Attachment #1: Type: text/plain, Size: 744 bytes --]

On powerpc64--linux, annota1.exp has two problems:

1) A breakpoint in a shared object may be 'delayed'.  This changes GDB's 
responce: both when the breakpoint is set and when it is hit.

2) Due to a bug (I which I knew the number), GDB 'skids' past the top-of-stack 
when doing a backtrace.  This causes two extra and severial garbage stack 
frames to be displayed, eventually getting an error.

I have attached three patches: seperate patches for these two problems and one 
patch that fixes them both.  I have also attached test logs so you can see 
what's up.

Ok to commit? (which one(s)?)

-=# Paul #=-

PS:  I thought the 'skidding past top-of-stack' problem was fixed.  But it 
doesn't seem to be in cvs-main as of last week sometime.

I'm not sure what you mean.  On i386 GNU/Linux, annota1.exp gets zero 
fails so this would suggest some sort of ISA specific bug?

I see this lets GDB accept the ``warning: adjusting breakpoint'' 
message.  I'm wondering if GDB should even emit the warning - it and the 
descriptor are very much integral parts of the ABI - and hence should be 
trying to always display the descriptor symbol and code address (and not 
display the dot symbol).

What's going to happen when 64-bit PPC stops emiting those dot symbols?

You mean backtracing past main - that code was recently rewritten. 
However, there's apparently no test case for the feature, perhaphs it it 
should first be added and fixed?.  Anyway, I don't think we should be 
passing a broken backtrace.

The problem is specific to any ISA that uses delayed breakpoints...  I think 
that's just the Power64.

I think I agree.  Unless this level of detail is needed by the user for some 
reason.  And I don't think they need to be reminded every time the breakpoint 
is hit.  But that's the way the code is.  The testsuite should reflect the 
way the code is, and to a certain extent, the way it was.

When this happens, then the regexp that I added would never be matched.  So 
Its kind of self correcting.  Some time later we can just remove the regexp.

Well... this doesn't 'pass' a broken backtrace, it just doesn't let a broken 
backtrace stop it from testing what it is really interested in: annotations.

I agree that we need a test for the 'backtracing past main' problem.  I will 
post one later today, along with a log showing it in action.  Which .exp file 
would you suggest I use as a model?

Re: [PATCH] Fixes testsuit/gdb.base/annota1.exp

[Andrew Cagney]

Paul,

Some history

For GDB, if we analize a test failure and identify a bug, we can mark it 
up with a KFAIL (and file a bug report).  This way we leave a trail of 
what is analysed while not hiding the bugs.  In the past people were 
going round XFAILing or PASSing such cases (the sole objective being to 
artifically deflate the fail numbers).

Another past mistake was to hack test cases so that they would 
(incorrectly) accept bogus backtraces.  Again, if we encounter this, we 
should KFAIL it, or better fix the bug.

This sounds like a KFAIL.

Andrew,

(I am sorry if this is just a rehash of the past, but it's new to me :-)

The problem of backtracing past main.  It shows up when debugging a 64-bit 
application.  it does NOT show up when debugging a 32-bit application.  Both 
on powerpc64--linux.

So when testing annotations, it will be a known failure on powerpc64--linux, 
when debugging a 64-bit application, because backtrace went past main.

I agree it is a known failure.  But it has nothing to do with annotations.  
Annotations work fine.  

I can see what a mess we would have if each test started trying to defend its 
self against bugs outside of the area being tested.

It it well known that a 'KFAIL' durring a test may have nothing to do with 
what is being tested? 

Is there an equivelent failure for 'I just can't run this part of the test?'

OK, so I wrote a test for the 'backtracing past main' problem.  Here it is 
along with a couple of logs:

Re: [PATCH] Fixes testsuit/gdb.base/annota1.exp

[Michael Chastain]

I'm Trying to catch up on the thread.  I'll do all the fun pontificating
here and then get to the specific revised backtrace-past-main patch in
another message.

Let's start with the delayed breakpoint message.

The actual output of gdb is:

  warning: Breakpoint 3 address previously adjusted from 0x80c5a66c78 to 0x80c59643a8.                                                                                                                                                            ^Z^Zbreakpoint 3

That's an observed fact from gdb.log_after_bp_adjust_patch

There are two separate questions that arise from this fact:

  (1) should gdb print this warning?
  (2) if gdb prints this warning, is that a bug in gdb?

Part of the answer to (2) is that the test script should have a separate
arm in gdb_test_multiple for that warning.  So you are on the right
track there.

The next question is what the new arm should do.  It can either PASS
or KFAIL.  That depends on the answer to (1).  If it's okay for gdb
to print this warning, then the result should be PASS.  If it's not
okay for gdb to print this warning, then the result should be KFAIL.

Sometimes you really have to hold people's feet to the fire to get
an answer to (2).  People will say "it would be better if gdb did
not print XXX, but we kinda have to for now", and you have to keep
asking "gdb prints XXX.  Is that a bug or not?"  If you can't get
an answer, it's always safe to file a PR and KFAIL it.

If it is a KFAIL, or even if it's a PASS, it's useful to put in a
comment that recapitulates the discussion about the feature.
Something like: "this happens on ppc-64, because blah blah,
gilliam 2004-09-23".

paul> It it well known that a 'KFAIL' durring a test may have nothing
paul> to do with what is being tested? 

Yes.  The very first KFAIL was in gdb.cp/annota2.exp, for PR gdb/544,
which is not an annotation bug but is actually a control-c handling race
in the event loop.

Re: [PATCH] Fixes testsuit/gdb.base/annota1.exp

[Michael Chastain]

This is good work.  Here's my nit-picking.  The main issue is
generating backtrace.c versus a static file.

Michael

. ChangeLog entry

. Drop the "Please email any bugs, comments, ..." inside the file.

. It's elegant to generate the C program, but there are a couple of
  problems.  You're writing on the source tree which screws up people
  who run multiple test runs out of the same source tree simultaneously.
  And all the external calls need error checking.  And there is a
  copyright notice in backtrace.c, but no license.

  Just drop the generation and supply backtrace.c like a normal file.
  That loses the ability to change subr_depth easily, but that's okay.

. subr_depth is still cool, you just have to document that it has to
  match backtrace.c.

I'm going to let these go for now.  When we get backtrace.exp
settled, you can submit these again.  Please submit each patch
separately.
