nordland 2001/09/19 14:36:04 PDT Modified files: src parser.y Log: Fixed the incorrect acceptance of rank-2 types like (Ord a => Tree a) -> IO () The parser now insists that such types be explicitly quantified, as in (forall a . Ord a => Tree a) -> IO () This also holds for the (somewhat counterintuitive) syntax for constructors with local existential quantification, i.e., Ord a => Con (Tree a) is banned in favor of forall a . Ord a => Con (Tree a) *Note*, however, that this fix doesn't solve the "rank-2 implicit parameters" problem reported by John Hughes earlier today: foo :: ((?x :: Int) => b) -> Int -> b foo s z = s with ?x = z Was that feature anticipated? In any case, there are two problems that must be solved here: (1) Loosen up the syntax somehow so that local monomorphic contexts are allowed -- perhaps by allowing (forall . (?x :: Int) => b) -> Int -> b (2) Fixing the erroneous unification that John describes. [Who will take the lead and define what all the common Haskell extensions really mean when used in conjunction?] Revision Changes Path 1.23 +3 -4 hugs98/src/parser.y

nordland 2001/09/19 12:14:07 PDT Modified files: src connect.h input.c machdep.c Log: Reimplemented the file search algorithm according to the following principle. I assume that the file found will be the first readable filename in the list produced by "find". find along nm hugspath = [ d++f++e | f <- files, d <- dirs, e <- exts ] where (pref,name) = rspan (/=slash) nm dirs = if null pref then along : hugspath ++ [""] else [pref] files = if isQModId name then [mod2dir name, name] else [name] exts = ["",".hs",".lhs"] rspan p s = let (a,b) = span p (reverse s) in (reverse b, reverse a) mod2dir s = map (\c -> if c=='.' then slash else c) s isQModId s = -- is s a valid qualified module identifier? The SEARCH_DIR option is still compatible with this principle, although it is turned off by default.

The license status of hslibs/util/Regex.hs is questionable, and hslibs/util/cbits/regex.c is GPL. There's a replacement designed to use the POSIX regex API in fptools/libraries/core/Text/Regex/Posix.hs. Cheers, Simon

by Alastair Reid 04 Sep '01

04 Sep '01

reid 2001/09/03 16:40:17 PDT Modified files: lib Prelude.hs tests testScript.in tests/libs except1.output prodcon.output tests/rts ioerror1.output mvar.output Log: This commit is all based on the following change to the scheduler loop in the Prelude: 1766c1766 < loop (Hugs_ForkThread a b:r) = loop (b:a:r) --- > loop (Hugs_ForkThread a b:r) = loop (a:b:r) [all other changes are to make the testsuite happy with the change] This has the effect of changing what happens when a thread becomes runnable. The old behaviour was to schedule the new thread immediately. That is, the new thread would preempt the current thread. The new behaviour is to maintain the current thread and just add the new thread to the list of runnable threads. The effect of this is that a thread executing a sequence of takes and puts (e.g., the sequence involved in reading from or writing to a Chan) will not be preempted unless one of the takes is on an empty mvar or one of the puts is on a full mvar. This is important because of one of the subtleties of the Hugs' thread implementation: each invocation of hugsIORun (e.g., the initial call to main, callbacks from C code, calls to unsafePerformIO, etc.) creates its own list of runnable threads and runs until all threads in that list are done (and, reports deadlock if the main thread from that invocation hasn't returned a value). Since threads cannot migrate from one runnable list to another, there's a distinct possibility of deadlock when the main thread in one invocation is blocked waiting for a thread in another list to wake it up. [I saw exactly this happening in the Win32 implementation of the HGL where callbacks from C into Haskell insert events into the event channel of each window. One thread would start writing to a Chan object but would get preempted before it finished. The preempting thread would then make a call to C which calls back into Haskell and tries to read the value written to the Chan. But it isn't allowed to read the value until the writer completes so it blocks. Now the writer should start running again but it can't because, although it is runnable, it is on a different runnable list so it gets ignored. So now the runnable list is empty and the callback terminates with a deadlock error message.] The most obvious fix would be to create a single global mutable list of threads but I'll save this (huge!) change for another day. [If anyone wants to take a stab at this before I get round to it (next 3-4 day weekend :-)), feel free. That'd probably be a good time to try implementing GHC's killThread and other asynchronous exception features.] A simpler fix is to prevent the first thread from being preempted unless it actually blocks. This change required changes to the sample output in the testsuite. All changes are either: 1) A permutation of the lines in the old file; or 2) Correcting for the change in the output format of IOErrors. (Should have been a separate fix but I only just noticed the problem.)

Can do better though, but this implementation will have to do for now. Regression tests to follow soon.

hslibs/ and hugs98
by Sigbjorn Finne 22 Jun '01

22 Jun '01

Hi everyone, Alastair's recent checkin gave Hugs98 access to a great many of the modules provided by fptools/hslibs, which is great. What about adding these derived modules to hugs98/lib in the CVS repository? I know very well there are downsides to replication, but having a CVS tree that's self-contained does have its merits. As is, you need to do a sep. checkout (but see below) & have to be on a UNIX box to generate the Hugs versions of the hslibs/ modules. Thoughts? --sigbjorn btw, you can now get at the contents of hugs98/ and fptools/hslibs in one go via the virtual CVS module 'hugs98dev' -- fptools/hslibs is checked out as hugs98/hslibs/hslibs (anyone well trained in CVS 'modules' setups is welcome to have a go at changing this to hugs98/hslibs ;-) ).

A module name A.B.C is mapped onto the file path A/B/C{,.hs,.lhs}, which is appended to each of the path prefixes in HUGSPATH during module import, until the name of a readable file is found. For backwards compatibility, string constants can still be used instead of modulenames if the location of a module doesn't conform to this pattern. Recursive scanning of subdirectories is no longer supported, though, nor automatic scanning of the directory where the previous module loaded was found. Still left to do: Update the library structure *and* the names of modules not located in the top level lib directory. Set up a default HUGSPATH that corresponds to the new structure.

New IO impl and modules
by Sigbjorn Finne 09 Jun '01

09 Jun '01

Hi, I'd encourage people to compile and test the IO, Directory, and CPUTime support I've just committed. The added primitives call upon misc OS functionality, which might not be present on a particular platform (or live in a different header file etc.) I believe I've augmented the configure script so this won't be an issue, but you never know about these things.... btw, if you don't want Directory and/or CPUTime support, prelude.h contains #defines that control this. The IO impl is mostly Haskell98 compliant; the main bit it doesn't implement is the H98 file locking rules. --sigbjorn

When you checkout Hugs, you should do this to obtain up to date copies of these files (and of all other hslib modules that currently work - about 90 modules in total). cvs checkout fptools/hslibs cd hugs98/src/unix convert_hslibs ../../.. # path points to base of fptools Revision Changes Path 1.4 +5 -5 hugs98/tests/testScript.in

cvs commit: hugs98/src preds.c prelude.h
by Jeff Lewis 18 May '01

18 May '01

lewie 2001/05/17 16:16:14 PDT Modified files: src preds.c prelude.h Log: This is really mostly a test commit. This helps hugs along w/ some of the more `interesting' fundep examples, but a final solution it is not. When checking entailment of a derived instance decl, you check entailment of each predicate in the context. Each of these checks may give rise to more opportunities for `improvement'. This patch adds an improvement step in between entailment checks. Revision Changes Path 1.28 +3 -2 hugs98/src/preds.c 1.17 +4 -4 hugs98/src/prelude.h
