The machines I used all have python, I had to hack the .sh version to avoid
using the python one to make sure I applied the same changes to both.

However, the .sh version does call 'sort' in some cases.
If you feed it with an input like:
Running my.exp ...
PASS: test1
WARNING: program timed out
PASS: test2
Running my.exp ...
PASS: test3
WARNING: program timed out
PASS: test4
(that is, twice the same .exp), the output is:
* before my patch:
Running my.exp ...
WARNING: program timed out
WARNING: program timed out
PASS: test1
PASS: test2
PASS: test3
PASS: test4

* after my patch:
Running my.exp ...
PASS: test1
PASS: test2
WARNING: test2 program timed out.
PASS: test3
PASS: test4
WARNING: test4 program timed out.

I tested only with gcc results, for which there might not be the same problem
(the tests are run in alphabetical order within one .exp file). Do you know
why results are sorted in the first place?

I looked at that some time ago, but never managed to find a solution
that I thought would be easily acceptable. I feared that some
people/scripts depend on the actual message format and was
reluctant to do that. But your proposal sounds reasonable.

As you say, changing DejaGnu means it will take time to have the patch
widely used. Changing gcc-local harness can break other scripts,
hence I thought it was safer to change the consumer of .sum files.

Sorry, in our testing we focus on c/c++/fortran so I missed the
others. However, my understanding of your comments is that
sequential builds do not suffer from this ordering problem?

Hi Christophe,

I know I'm coming quite late to this, but I've got quite a number of
problems with your approach.

> at the end of each .exp section when it generates .sum files.

This is only true when dg-extract-results.py is used.  When it is
disabled or no python present and thus the shell version is used, this
issues doesn't exist.  There are other even more severe issues with how
the python version sorts lines, as has been observed in the gdb
community:

https://sourceware.org/ml/gdb-patches/2018-10/msg7.html

Even when passing just a single .sum files to dg-extract-results.py, the
order changes.

I fear this is the wrong approach: DejaGnu owns the .sum format and they
need to be involved in extensions.  Besides, it should be possible to
satisfy the need to have this approved and incorporated upstream and not
having to wait for a long time until gcc can use it: AFAICS it should be
possible to wrap DejaGnu's warning proc in a gcc-local version that
checks for the "program timed out" arg and extracts the test name from
the caller that has it (dg-test) using uplevel.  I've just not checked
yet if the call depth from dg-test to warning is constant in the case we
care about.

> What do people think about this?

I've more problems with your approach:

* When done in dg-extrace-results.sh/py, it only works for parallel
  tests.  Both sequential tests (like libgomp and several others) and
  sequential builds don't get the additional information.  Having to
  filter every single .sum/.log file through dg-e-r seems totally
  wasteful to me.

* Right now, your patch fabricates misleading timeout information,
  e.g. I've seen

WARNING: g++.dg/cpp0x/enum32.C  -std=c++14  (test for errors, line 24) program 
timed out.

  where the original g++.sum file has

WARNING: program timed out
PASS: g++.dg/cpp0x/enum32.C  -std=c++14  (test for errors, line 24)
PASS: g++.dg/cpp0x/enum32.C  -std=c++14 (test for excess errors)

  and the original g++.log

/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cpp0x/enum32.C: In function 
'int main()':
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cpp0x/enum32.C:24:7: error: 
'C::D C::y' is private within this context
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/cpp0x/enum32.C:19:4: note: 
declared private here
WARNING: program timed out
compiler exited with status 1
PASS: g++.dg/cpp0x/enum32.C  -std=c++14  (test for errors, line 24)
PASS: g++.dg/cpp0x/enum32.C  -std=c++14 (test for excess errors)

  The only two places where DejaGnu can emit the "program timed out"
  message is for either the compilation timing out or exection timeouts.
  So the only messages that make sense would pertain to those, not stuff
  about other tests.

I think those issues warrant persueing the alternative approach I've
lined out above.

ok for now to avoid silently losing considerable parts of the test
results.  However, I've lots of problems with the current approach which
I'll detail in a separate reply to your original test submissions.

So the problem happens when a WARNING is the first result of a new harness.
This is fixed by the attached dg-extract-results.patch2.txt.

While looking at it, I noticed that the ordering wasn't right with the
shell version,
though I did test it before sending the previous patch.
The attached dg-extract-results.patch1.txt makes sure the WARNING: line
appears before the following testcase with the shell version too.

Are both OK?

Sorry for the breakage.

Can you send me the .sum that cause the problem so that I can reproduce it?

I just had a case where your patch broke the generation of go.sum.
This is on Solaris 11.5 with python 2.7.15:

first_key = key
UnboundLocalError: local variable 'key' referenced before assignment

Before your patch, key cannot have been undefined, now it is.  I've
verified this by removing the WARNING: lines from the two affected
go.sum.sep files and now go.sum creation just works fine.

There are a few improvements we might want to look at;
 1) application to the libraries (other than libstdc++)
 2) things are inconsistent between -j1 and -jN check runs because the 
dg-extract doesn’t seem to be run for j1.
  - this means that the timeout warnings are not changed
  - but it also seems to remove the sorting (for some reason I thought that was 
part of test_summary), which means that one can’t compare a -j1 run with a -jN 
run easily (or so it seems from some quick tests).

.. won’t have any cycles for looking at this in the next few weeks - but a 
“heads up” anyway.

Good news.
I didn't imagine there were differences in the way results are
extracted between our various tools/libs.

Please do, I don't plan to check libgomp.

So it seems that the only library testsuite that uses dg-extract-results is 
libstdc++v3.  This explains why the script wasn’t applied to libgomp.  It DTRT 
if applied manually.

I guess an edit of the various library testsuite Makefile(s) to generate the 
original .sum file as a temp followed by dg-extract-results to the final file 
would work.  Will try it when I have a few moments (unless you get to it first 
;) )

If you still have the logs, you can run the script manually.

My worst-cases are a couple of PCH-related that are still unanalysed.. but 
those are not the only ones.
+ when I use VMs to cover some of the earlier versions of the system, they are 
much more prone to occasional timeouts.

> Did it work for you?

So far it’s looking nice… (anything that makes the dg output more stable is 
Good in my book)

… I am not sure (not checked thoroughly) but I think I saw one case in libgomp 
testing where it didn’t pick up the timeout, will poke some more at that if i 
see it again.

thanks for the patch!

It seems a good idea (for those of us with targets prone to timeout issues).
