Description (last modified by )
There are several improvements that would be good to make, including but not limited to:
 Forking rather than starting up a new Sage each time.
 Customizable comparison rather than mutating doctests into new doctests (e.g. followup to #10952).
 Eliminate need to write temporary files for every doctested file.
 Constant headaches caused by the difference in doctesting library vs. nonlibrary files.
 The ability to drop into a debugger if a doctest raises an exception.
Robert's code is at
http://code.google.com/p/sagemathtimer/
and does most of the above (plus more which has been moved to followup tickets #12720 and #12722)
Apply 12415_framework.patch, 12415_doctest_fixes.patch, 12415_doc.patch
Apply 12415_script.patch to the scripts repo
Apply 12415_spkg_bin_sage.patch to the root repo

12415_2.patch seems to contain a lot of tempfile changes, could you split out the doctest changes into a separate patch (or are these affecting doctests?)

 Status changed from new to needs_review
Ready for review!
There are still a few known issues:
 valgrinding under sage t doesn't work. I haven't used valgrind much and don't know how to resolve this.
 The fix at #13147 probably needs work: I'm getting a failure in
sage.rings.polynomial.multi_polynomial_libsingular
to do with garbage collection. I'm working on it.  I'm in the process of updating the developer guide.
But I wanted to get some other people involved in reviewing.
comment:20 Changed 9 years ago by
This may be a silly question, but how do I use the new framework? Don't we need changes to the scripts repo, too? (If I just run sage t FILES
, I don't see the various messages, like Doctesting ...
, that should be printed by run_doctests
are not printed, so sage t
is not yet using the new framework.)
One of the patches also didn't apply cleanly to 5.1.beta5:
hg qimport P ~/Downloads/12415_stderr.patch adding 12415_stderr.patch to series file applying 12415_stderr.patch patching file sage/lfunctions/lcalc.py Hunk #1 FAILED at 226 1 out of 2 hunks FAILED  saving rejects to file sage/lfunctions/lcalc.py.rej patch failed, unable to continue (try v) patch failed, rejects left in working dir errors during apply, please fix and refresh 12415_stderr.patch

The description is updated: let me know if you have any more problems. I think you need to apply 12415_stderr_vs_51b5.patch instead of 12415_stderr.patch.
comment:24 Changed 9 years ago by
Regarding 12415_spkg_bin_sage.patch, the file in question should be part of the root repo.
comment:25 Changed 9 years ago by
One regression: with the old setup, running sage tp FILES
(with no argument for tp
) would choose the number of threads automatically. With the new setup, this command gives an error, because FILES
is not an integer. Therefore I think that, for example, make ptestlong
will fail. (The file sageruntests says that the default value for nthreads is 1, but I don't think optparse is dealing with the missing argument properly here. Also, passing the argument 0 causes doctests to never happen: maybe it's using 0 threads instead of minimum(8, cpu_count())
.
comment:26 Changed 9 years ago by
I would suggest the following two changes: for the scripts repo:

sageruntests
diff git a/sageruntests b/sageruntests
a b import optparse, os, sys 5 5 if __name__ == "__main__": 6 6 parser = optparse.OptionParser() 7 7 8 parser.add_option("p", "nthreads", type= int, default=1, metavar="N", help="tests in parallel using N threads with 0 interpreted as minimum(8, cpu_count())")8 parser.add_option("p", "nthreads", type="string", default=1, metavar="N", help="tests in parallel using N threads with 0 interpreted as minimum(8, cpu_count())") 9 9 parser.add_option("serial", action="store_true", default=False, help="run tests in a single process in series") 10 10 parser.add_option("timeout", type=int, default=1, help="timeout (in seconds) for doctesting one file") 11 11 parser.add_option("a", "all", action="store_true", default=False, help="test all files in the Sage library") … … if __name__ == "__main__": 49 49 parser.add_option("stats_path", "statspath", default=os.path.join(os.path.expanduser("~/.sage/timings2.json")), \ 50 50 help="path to a json dictionary for the latest run storing a timing for each file") 51 51 52 options, args = parser.parse_args() 53 try: 54 options.nthreads = int(options.nthreads) 55 except ValueError: 56 args.insert(0, options.nthreads.strip()) 57 options.nthreads = 0 58 59 if options.nthreads == 0: 60 try: 61 options.nthreads = int(os.environ['SAGE_NUM_THREADS_PARALLEL']) 62 except KeyError: 63 options.nthreads = 1 64 52 65 from sage.doctest.control import DocTestController 53 DC = DocTestController( *parser.parse_args())66 DC = DocTestController(options, args) 54 67 err = DC.run() 55 68 sys.exit(err)
and for the Sage library:

sage/doctest/control.py
diff git a/sage/doctest/control.py b/sage/doctest/control.py
a b class DocTestController(SageObject): 433 433 else: 434 434 nother += 1 435 435 if nfiles + ndbsources + nother: 436 self.log("Doctesting %s."%(", ".join((["%s file%s"%(nfiles, "s" if nfiles > 1 else "")] if nfiles else []) + 437 (["%s other sources"%nother] if nother else [])))) 436 self.log("Doctesting %s"%(", ".join((["%s file%s"%(nfiles, "s" if nfiles > 1 else "")] if nfiles else []) + 437 (["%s other sources"%nother] if nother else []))) 438 + " using %s threads."%self.options.nthreads if self.options.nthreads > 1 else ".") 438 439 self.reporter = DocTestReporter(self) 439 440 self.dispatcher = DocTestDispatcher(self) 440 441 try:
Or something like that. I guess you should also print the number of threads when you print "Doctesting entire Sage library.", etc.

I've updated the option parsing to allow p to take no options (though I used a callback so that the p doesn't have to be last). I changed 12415_spkg_bin_sage.patch to be an actual patch against the root repository. I also made a small change to the debug functionality (printing the doctest that failed before dropping into the debugger).
Since I'm modifying four repositories, I'll just update the patches rather than creating lots of referee patches (unless the referee objects!).

I guess you're no longer using the scripts sagetest

, sagedoctest
, sagemaketest

and sagetestimport
. Remove these.

Replying to jdemeyer:
Why does the doctesting framework need to be imported from
sage.all
?
I don't think it needs to be, but it makes it easy to test (and debug) doctests from within Sage:
sage: run_doctests(sage.rings.integer) ...

You have two instances of
except:
in the new code.
The one for os.kill()
should just catch OSError
, for the other one replace
except KeyboardInterrupt: pass except:
by
except Exception:

Replace
import multiprocessing options.nthreads = os.getenv('SAGE_NUM_THREADS_PARALLEL',min(8, multiprocessing.cpu_count()))

options.nthreads = int(os.getenv('SAGE_NUM_THREADS_PARALLEL', 1))

wheel)

Am I doing something wrong?

Some of these are due to a bug in the change I just made to p. I'm working on fixing those.
Some look like you didn't apply the patch to the sagenb repo. Did you forget, or is something else going on?
Some are due to the fact that in your tests, os.system calls are happening before the python process gets far enough, so results that were printed to the screen in the wrong order. I'm guessing this may relate to the fact that you're running on /release, since my tests on sage.math didn't show the same behavior.
I'm in the process of fixing stuff.

There's some code in the current doctesting code to output xml results, which I'm not currently duplicating. Is this used somewhere?

Currently sage t new is broken. I'm trying to figure out why.
comment:46 followup: ↓ 78 Changed 9 years ago by
Alright, I'm going to start running tests. There are still some remaining issues, but the patches are in a state where someone else might want to look at them. :)
Remaining problems:
 #13145 needs work, generating some doctest failures related to deallocating multivariate polynomials
 hg_sage seems to be broken, causing the new option to fail
 valgrinding
sage t
doesn't work; I'm not sure whether it did before  The new code doesn't support xml output
I'll see if I find more when running sage t all
.

Use sys.stdout.flush()
(and/or the same for stderr
) before os.system()
to overcome this. The difference is probably that my output was sent to a pipe, as opposed to directly to the terminal. In the latter case, flushing is automatic.
True, I might not have applied all patches correctly.

It doesn't make sense to patch the old notebook. Please work with the flask notebook instead (i.e. make this ticket depend on #11080 and preferably #13121).
I agree that it doesn't make much sense to patch the old notebook, but if this can get a positive review quickly I'd rather not wait on #11080 and #13121. The changes to the old notebook are pretty minor.

Design question: when running tests in parallel, failed examples are printed as they arise, meaning that examples from different files are intermingled. Is this a problem that needs to be fixed?
comment:51 Changed 9 years ago by
 Status changed from needs_work to needs_review
The only tests I have failing on sage.math are sage.tests.startup
and sage.rings.polynomial.multi_polynomial_libsingular
(due to #13145).

It might not be truly a problem, but I prefer the current model where the tests for one file are grouped.

Even better might be an option to show only the first failure in each file.

I've updated the code to group results for each file, and added an option (sage t initial

The previous doctester would reduce the number of threads to be at most the number of files to test.
comment:59 Changed 9 years ago by
A very useful feature from the previous doctester which is missing here is that verbose
actually shows the output as the test is running. So when it gets stuck somewhere, you actually see that it gets stuck. Currently, the whole test result is simply dumped at the end.
Also: previously, line numbers were shown with verbose
(albeit in a very bad way).
One more featurerequest: with verbose
, show the time taken for each single test, i.e. I would like
Trying (line 242): EllipticCurve('900d1').integral_points() Expecting: [(11 : 27 : 1), (4 : 34 : 1), (4 : 18 : 1), (16 : 54 : 1)] ok [0.10s] Trying (line 243): E=EllipticCurve([879984,319138704]) Expecting nothing ok [1.92s] Trying (line 255): P1=E.point((540,1188)); P2=E.point((576,1836)) Expecting nothing ok [4.59s]
It's totally okay for me to disallow verbose
in parallel tests.

New version posted. sage t long a
passes all tests except the one related to #13145.
/home/jdemeyer/doctest/keyboardinterrupt.py
passes if you remove the trailing colon. I've updated the framework to recover a bit more gracefully if a doctest raises an unexpected KeyboardInterrupt?, but it behaves a bit strangely since it's difficult to distinguish between an actual interrupt (in which case the testing should terminate) and one raised by a doctest (in which case tests of other files could continue). I think the new behavior is actually fairly reasonable: try it on your file without removing the colon.

Sure, and for reporting what happened to the user this is fine. But from the child process' perspective, an unexpected KeyboardInterrupt
has been raised and it should stop testing that file. The parent process can continue the doctests though....

I'm fine making it less prominent (having it not show up in the help display for sage t

, which should available through sage t ...
, right? Which of these new options should be documented in the help messages usage
and/or usage_advanced

I thought I'd solved the sporadic problem in sage.tests.interrupt by increasing the delays in test_sig_block_outside_sig_on
: after the change I ran sage tp sagenb long devel/sage/doc/common devel/sage/doc/[az][az] devel/sage/sage
10 times with no failures (where before there had been 5 failures in interrupt.pyx
). But I just got another one. Maybe it has to do with the load on sage.math? There are more processes running now than when I ran the test earlier.
Jeroen, would you be willing to take a look at it since you wrote the tests in that file?
All the other tests pass for me, with the exception of startup.py.

Agreed, but I'm at a loss for what's causing the problem, and it's difficult to debug since it's sporadic and a segfault.

Concerning the logfile error: I think you are making the mistaken assumption that $SAGE_TESTDIR

That's because your expected output has an extra colon. If you delete the trailing colon it passes tests.
With the extra colon it's an unexpected KeyboardInterrupt

Yeah, that shouldn't be a problem. But I'd like to put a feature freeze on this ticket and open a new ticket for it: I'm already regretting adding the new debugging feature since I'm struggling with debugging its interaction with KeyboardInterrupts

 It occurs only if

The problem seems to be caused by
sage: test_sig_block() 42
but it only shows up if enough time is taken up by later tests. So you can delete
sage: from sage.tests.interrupt import * sage: for i in range(4): # Several times to reduce chances of false positive ... test_signal_during_malloc()
and add something else, and you still get the error.

Also, the directory devel/sagenb/sagenb/data
should probably not be tested, as there are failures because of TAB characters in the MathJax rst documentation.

Do you guys consider it a feature or a bug that
""" sage: 1e16 # relative tol 1e10 10^16 """
doesn't work? See #12815.

What I'm missing in this patchbomb is a highlevel overview of how everything works. To me, it looks like a large lump of code (which seems to work pretty well) which is hard to understand.

Typo:
Comparison ist just comparison of the underlying lists.

Replying to roed:
Robert wrote that code. :) I think the issue is that some doctests may spawn new processes that can survive their death. Do you have an alternate approach to suggest?
There is some commentedout code mentioning process groups, it would be a good idea to make that work.
But I'm also a bit lost on how the fork()ing actually works and how many Sage sessions are involved.

I will add somw top level documentation next week.

#13908 might also help with proper killing.

Looks like I have to depend on this for the numpy1.7 upgrade at #11334, so I am tagging along :)
comment:150 Changed 9 years ago by
It is interesting. With each new version of numpy we seem to have new instances of
Warning: divide by zero encountered in divide
appearing in doctests. This suggest that numpy sometimes mixes stderr and stdout or that they are very intent to tell you about these warnings. All the instances of this warning that are fixed in 12415_stderr_vs_51b5.patch also appears with the upgrade to numpy 1.7.0  plus some more.

 Description modified (diff)
Combined 12415_stderr_vs_51b5.patch and 12415_doctest_fixes.patch and rebased.
12415_framework.patch needs to be rebased but displayhook.py
changed substantially in #12719, so I don't know what to do.
I'm working on this. Email me if you want to collaborate.
