Possible heisenbug in test suite (not in individual test runs) with memoization

[David James]

I've got a Clojure test suite that fails when run as whole but passes when
run piecemeal. This just started happening. I've tested the code
thoroughly. The bug pops up in a part of the code that I did not change.
So, at present, it feels like a heisenbug!

These may be some relevant pieces:
* I'm using memoization; the failures happen in memoized functions.
* I'm doing a lot of various precision BigDecimal math.

Some tentative guesses:
* Somehow one test is affecting another test

Questions (there are speculative):
* What are some possible ways that memoization might fail (e.g. return an
incorrect value)?
* Is it possible that higher memory usage could cause memoization results
to get lost?

Unfortunately, it is a sizable code base, and I don't have a small,
reproducible example. Any suggestions?

-David

Re: Possible heisenbug in test suite (not in individual test runs) with memoization

[Justin Kramer]

Shot in the dark: check that arguments passed to your memoized functions 
use consistent typing. A BigDecimal such as 1M does not necessarily equal 1 
(a Long):

> (= 1 1M)
false
> (== 1 1M)
true

Your memoized functions could be recomputing values unnecessarily if you're 
giving them different types of numbers.

I’m not aware of one.

Walking the classpath including the contents of jar files would be a way to 
construct such a list of USE-able (or REQUIRE-able) namespaces. It would 
involve  traversing the directory structure under each entry in the classpath 
and reading at least the first ns form in each candidate file (or jar entry).

IIUC, completing et al does not work for ClojureScript because
ClojureScript, not because of tooling. I have no idea how or if
development towards that end is going, but I believe it has something
to do with limitations of the host language which does not get my

Re: ClojureScript integration with Emacs/Cider ?

[Colin Fleming]

Since Cursive (http://cursiveclojure.com) resolves everything statically
from source, ClojureScript completion and navigation works for most
symbols. There are still a lot that it doesn't know about since
cljs-specific functionality is still pretty low, so js/* symbols have no
support, and any functions included from Closure are not found either. But
for pure cljs it should work pretty well. There are quite a few people
using Cursive for cljs dev now, despite the slightly embarrassing lack of
explicit support :-)

Re: [ANN] data.avl 0.0.10 -- fast sorted maps and sets with log-time rank queries

Thank you, happy to hear this might be useful!

As for rank-of's -1: the reason is as Mikera said. I wanted to be
consistent with primitive-returning Java methods like indexOf and to
be able to hint rank-of to ^long (although I haven't yet -- 0.0.11, I
guess!).

This is not the only sensible thing to do; I was thinking about maybe
adding variants of rank-of which would find the index of the "first <=
/ =>" element according to the comparator (which would still return -1
for empty collections and elements less / greater than the extreme
elements of the collection, but not for those in between a pair of
existing keys):

(rank-of-<= (avl/sorted-set 0 2 4) 3)
;= 1

(rank-of->= (avl/sorted-set 0 2 4) 3)
;= 2

(rank-of->= (avl/sorted-set 0 2 4) 2)
;= 1

Alternatively rank-of could take an optional argument to force this
behaviour; we could even use < / <= / >= / > like subseq does.

In fact, apparently there's a relevant ticket in the tracker already:
DAVL-1 [0].

It's doable right now with subseq / rsubseq:

(defn rank-of-<= [coll x]
  (if (empty? coll)
-1
(let [r (avl/rank-of coll x)]
  (if (== -1 r)
(let [s (rsubseq coll <= x)]
  (avl/rank-of coll (first s)))
r

(mapv #(rank-of-<= (avl/sorted-set 0 2 4) %) [-1 0 1 2 3 4 5])
;= [-1 0 0 1 1 2 2]

But a direct approach would no doubt be faster.

Any ideas re: possible API, comments on the usefulness of such
additions etc. would be very welcome!

Cheers,
Michał

Re: Possible heisenbug in test suite (not in individual test runs) with memoization

[Cedric Greevey]

It's possibly an interaction between memoization and dynamic vars; more
specifically, a result might be being memoized with one with-precision
context active, and then recalled with a different one active, with
arguments that compare equal despite the different precisions (say, because
those arguments that are BigDecimals are exactly representable at the lower
of the two precisions). If the result is *not* the same at the higher
precision, that could cause an expected-equal check to fail in your test.

I'd also wonder at possibly having a test work if it used a memoized result
generated earlier with a finite precision in effect, and fail with
ArithmeticException without the memoization if the test doesn't set a
precision limit itself and the result's not exactly representable at any
finite precision (e.g. 1/7); but this would likely result in a test that
worked in the suite and failed in isolation, instead of the reverse.
However, if high memory use is causing a memoized value computed at limited
precision to be "forgotten" and then recalculated with no precision limit,
that might trigger failures in the suite of tests that worked in isolation.

In any event, subtle interaction of with-precision's underlying dynamic var
*math-context* with memoization is an obvious suspect worth investigating,
even if it might ultimately be acquitted by the jury. :)

Re: Cute Clojure tricks

[curiousGuy]

This is extremely disappointing, that the flag must change when the U.S. 
takes over all of North America. I suspect that this issue on flag design 
will be the likely reason that this never happens.

Re: ANN: Om, a ClojureScript binding to Facebook's React

Perl Regexp::Grammars in Clojure?

[gvim]

I'm fairly new to Clojure, having spent many years working with Perl. 
One area where Perl has always shone is regular expressions and text 
parsing. Perl 6 took this one step further with grammars and the genius 
that is Damian Conway managed to port Perl 6 grammars to Perl 5:


http://search.cpan.org/~dconway/Regexp-Grammars-1.033/lib/Regexp/Grammars.pm

I'm just wondering what a Clojure version of Regexp::Grammars would look 
like :). Anyone up for the challenge?

Re: Perl Regexp::Grammars in Clojure?

[Andy Fingerhut]

Mark Engelberg's Instaparse most likely does not have the same feature set
as Regexp::Grammars (I haven't checked in enough detail to learn the
differences), but they do likely have features in common:

Re: ClojureScript integration with Emacs/Cider ?

[Bozhidar Batsov]

I'm cider's maintainer. The problem with code completion for ClojureScript 
is that the default mechanism is based on the Clojure-only 
library https://github.com/ninjudd/clojure-complete. As I don't use 
ClojureScript I haven't paid much attention to it so far. If there is a 
similar library for ClojureScript I might add support for it. Btw, cider 
will also pick up any nREPL middleware that provides a "complete" op - if 
there is a ClojureScript nREPL completion middleware it can be used with 
cider even now. Ideally at some point we'll have unified middleware 
supporting both Clojure & ClojureScript.
