Re: bug (?) in type checking of record update
by Ross Paterson 12 Feb '03

12 Feb '03

Jeff, I think this unification should be re-instated: --- type.c 12 Feb 2003 05:49:14 -0000 1.64 +++ type.c 12 Feb 2003 15:42:34 -0000 @@ -1814,11 +1814,8 @@ instantiate(t); shouldBe(line,snd(f),e,update,arg(fun(tr)),or); } /* Unmentioned component */ - /* this is just a sanity check, and avoiding it lets us - handle records with polymoprhic components else if (!unify(arg(fun(td)),od,arg(fun(tr)),or)) internal("typeUpdFlds"); - */ tr = arg(tr); td = arg(td); It always succeeds, because it just unifies the type variable for the input field with the one for the output one, but this affects the type of the expression, and may trigger later errors, e.g. we currently have data Container a = Container { contents :: a, info :: String } Hugs> :t Container { contents = True, info = "foo" } { info = "bar" } Container{contents = True, info = "foo"}{info = "bar"} :: Container a Would that break records with polymorphic components?

by ross＠glass.cse.ogi.edu 11 Feb '03

11 Feb '03

ross 2003/02/11 04:56:32 PST Modified files: libraries/Hugs Prelude.hs Log: dirty little kludge to make Rational literals work better. In Haskell, floating point literals are applications of fromRational; In Hugs, they're applications of fromDouble, a private method of Fractional. This is fine for the common case where Double is intended, but leads to embarassments like Prelude> 0.3::Rational 5033165 % 16777216 The real solution would be to use Rationals, but that would be hard for an interpreter to optimize. This hack changes fromDouble to yield a decimal fraction, hopefully the one the user gave in the first place, though some precision may be lost, and it doesn't work near the bottom of the range.

IO actions now take a single continuation rather than two, causing the stated arity of IO primitives built with these earlier versions of HugsAPI to be off by one. By keeping track of what IO representation an extension DLL assumes, we adjust the arity of IO primitives when they're added to the name table in storage.c:addPrims().

The old representation of exceptions was data Exception = IOException IOError | HugsException HugsException where IOErrors are passed to a failure continuation and printed using Show. HugsExceptions are redexes that caused an error, triggering a longjmp. If not caught, they get printed by the internal printer, e.g. {primDivInt 1 0}. Now: * the Exception type is copied from Control.Exception, which sadly makes the Prelude a bit bigger; there are no HugsExceptions. * all Exceptions trigger a longjmp, are caught by runAndShowError and printed using Show, e.g. "divide by zero" -- less information, but more friendly. As a result, +f (failOnError) now has no effect, although -u still works (slightly differently). * all of Control.Exception bar throw(Dyn)To works with Hugs. * the failure continuation in the IO type is unused, though it's still there for now. * now that exitWith throws an ExitException, an exitWith in a thread other than the main one is reported (like any other exception) but doesn't cause the program to terminate.

sof 2003/01/22 11:15:23 PST Modified files: src prelude.h static.c storage.c storage.h subst.c Log: Stephen Milborrow's optimisations to whatIs() -- enabled by defining FAST_WHATIS to 1 (which it is now by default.) Here's the original e-mail describing the changes made (and their effect): From: "Stephen Milborrow" <milbo(a)icon.co.za> To: <hugs-users(a)haskell.org> Subject: A Faster whatIs Date: Sat, 30 Nov 2002 11:10:47 +0200 Hello everyone: I made some changes to the Hugs sources which give small runtime speed gains. The results are in the table below. The gains are minor, but I thought some people in the group might be interested. WHATIS WHATIS1 FHEAP Speed Increase (percent) gamteb 8 9 5 parser 6 8 gcfail prolog 9 9 2 queens 10 13 4 Extra BSS memory (kBytes) 24 24 0 Nbr source lines changed 50 144 41 ---Notes On The Table The table headings WHATIS, WHATIS1, and FHEAP refer to three different sets of changes. WHATIS and WHATIS1 are described below. FHEAP was an experiment that simply used a fixed size heap (an array instead of a malloc) and is impractical because it rules out use of the Hugs -h flag. The (motley) collection of test programs are from nofib. I timed runhugs for each program without command line flags, except that for queens I used -h1000000. Different programs would probably give different results: the usual caveats apply. These programs were just the nofib ones I had at hand. I compiled with MSC 5.0 Service Pack 3 using modified Nov 2002 Hugs sources. I ran the timing tests on a Windows 98 machine. ---Strategy I wanted to see what speed gains could be achieved by taking a worm's eye view of the code, with no changes to fundamental algorithms. I also wanted to make changes that would be limited to just a few places in the code -- a minimal force approach. To start off, I ran the MSC profiler. This confirmed that whatIs() is a candidate for optimization, as already noted in Mark's Gopher implementation document and in comments in storage.c. But the profiler showed a few other hotspots too. (An interesting thing to do is sort the profiler results on execution line-count, which immediately tells you which are the most executed lines in the program.) ---WHATIS Change To reduce the time spent in whatIs, I created a byte array whatCode of whatIs codes. I then created a whatIs macro which replaces the whatIs function: #define whatIs(c) (isPair(c)? \ (isTag(fst(c)) ? fst(c) : AP ) : \ whatCode[c]) Negative indexing into whatCode is prevented by the isPair. To keep the size of whatCode reasonable, I had to reduce the range of unboxed ints -- the bigger the range, the bigger the whatCode array. I settled on a range of 2048 i.e. ints between -1023 and 1024 are unboxed, all others are boxed. The extra boxing will actually slow down execution of certain Haskell programs, but as far as I can tell the majority of real Hugs programs would be unaffected. Increasing this range to, say, 10 000 would increase memory usage by 10 000 bytes -- nothing really when you consider that the memory footprint of winhugs is about 10 MBytes. This change yields the speed improvements under the WHATIS column in the table. ---WHATIS1 Change IsTag is defined as #define isTag(c) (TAGMIN<=(c) && (c)<SPECMIN) I reduced the cost of IsTag slightly by changing defines in storage.h so that only box-cell-tags are in the range 1 to 0x7f. (I shifted special cell values down to start at 0x80). I then defined variants for IsTag and friends: #define isTag1(c) (((c) & TAG_MASK) == 0) #define whatIs1(c) (isPair(c)? \ (isTag1(fst(c))? fst(c) : AP ) : \ whatCode[c]) #define isAp1(c) (isPair(c) && !isTag1(fst(c))) whatIs1 is a faster version of whatIs, with the "bug" that it will return the wrong value if fst(c) is NIL. When used in several places as a replacement for whatIs, it gains us a few speed percentage points as shown in the WHATIS1 column above. WHATIS1 sits on top of WHATIS so the gains attributable to WHATIS1 alone are the differences between the percentages in the two columns. ---Another Candidate Another candidate for this kind of optimization is the line in eval(): if (!isCfun(n) && (ar=name(n).arity)<=(sp-base)) {... This is one of the most executed lines in the entire program. If the stored arity of Cfun's was offset by a largish number, say 10000, then the above test against isCfun wouldn't be needed. This change would introduce inefficiencies elsewhere (we would have to un-offset the stored arity before using it elsewhere) but the net effect would probably be a speed gain. I shied away from this change because it would require ubiquitous (though easy) code changes. ---Final Comments Optimizing code written by Mark Jones is a challenge. It becomes a little less daunting if we change the rules by allowing ourselves to waste some memory in the pursuit of speed, and to introduce some ugliness into the code. Even so, the speed improvements I got were small. If anyone is interested, I would be happy to send the sources. They are modified Nov 2002 sources with all the changes demarcated by #define's. Six files changed. I would be interested to know what results these changes give on other machines. --- Stephen Milborrow Revision Changes Path 1.40 +7 -2 hugs98/src/prelude.h 1.134 +7 -2 hugs98/src/static.c 1.59 +38 -2 hugs98/src/storage.c 1.48 +86 -2 hugs98/src/storage.h 1.26 +6 -2 hugs98/src/subst.c

proposed major change: Hugs and Exceptions
by Ross Paterson 16 Jan '03

16 Jan '03

Hugs has data Exception = IOException IOError | HugsException HugsException where IOErrors are passed to a failure continuation and printed using Show. HugsExceptions are redexes that caused an error, triggering a longjmp. If not caught, they get printed by the internal printer, e.g. {primDivInt 1 0}. In my tree, I've switched over to the full Exception type (as in Control.Exception), with all Exceptions triggering a longjmp, caught by runAndShowError and printed using Show, e.g. "divide by zero" -- less information, but more friendly. Almost all of Control.Exception (all but throwTo/throwDynTo) then works with Hugs. The failure continuation in the IO type is then unused, though it's still there for now. A disadvantage is that the Exception types and Show instances move into Hugs.Prelude. It touches quite a few files, but it passes the test suite (appropriately modified), and I'm thinking of committing it. Anyone want to advise caution?

It is copied by make install, and removed by make clean. The test scripts now use this in-place version, so they may be run prior to installation.

I'd like to propose eliminating the option of using the old library setup, and then dismantling it. (The new setup includes compatibility stubs.)
