Ticket #3531: don_t-build-haddock-if-haddoc_docs-_-no_-and-disable-haddoc_docs-if-ghcwithinterpreter-_-no.dpatch

Sun Sep 20 20:13:19 CEST 2009  Matthias Kilian <kili@outback.escape.de>
  * Don't build haddock if HADDOC_DOCS = NO, and disable HADDOC_DOCS if GhcWithInterpreter = NO
  Haddock uses TcRnDriver.tcRnGetInfo, which is only available if
  GHCI is built. Set HADDOC_DOCS to NO if GhcWithInterpreter is NO,
  and disable the haddock build if HADDOC_DOCS = NO.

 HEADS UP: this changes the format of event log files.  Corresponding
 changes to the ghc-events package are required (and will be pushed

 breaking the rules this time.  This will be the only time we can do

 Ignore-this: 9964cfe9d39b12eb10724cd1f3fee6b5
 
 This patch fixes test failures for the profiling way for drv001.
 The problem was that the arity of a function was decreasing during
 "optimisation" because of interaction with SCC annotations.
 In particular
       f = /\a. scc "f" (h x)    -- where h had arity 2
 and h gets inlined, led to
       f = /\a. scc "f" let v = scc "f" x in \y. <blah>
 
 Two main changes:
 
 1.  exprIsTrivial now says True for (scc "f" x)
     See Note [SCCs are trivial] in CoreUtils
 
 2.  The simplifier eliminates nested pushing of the same cost centre:
        scc "f" (...(scc "f" e)...) 
        ==>  scc "f" (...e...)

[Three improvements to Template Haskell (fixes #3467)
simonpj@microsoft.com**20090910125848
 Ignore-this: 40e480334a8cd06d128a845cefd4632a
 
 This patch implements three significant improvements to Template Haskell.
   
 Declaration-level splices with no "$" 
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 This change simply allows you to omit the "$(...)" wrapper for 
 declaration-level TH splices.  An expression all by itself is
 not legal, so we now treat it as a TH splice.  Thus you can now
 say
        data T = T1 | T2
        deriveMyStuff ''T
 
 where deriveMyStuff :: Name -> Q [Dec]
 This makes a much nicer interface for clients of libraries that use
 TH: no scary $(deriveMyStuff ''T).
 
 Nested top-level splices
 ~~~~~~~~~~~~~~~~~~~~~~~~
 Previously TH would reject this, saying that splices cannot be nested:
        f x = $(g $(h 'x))
 But there is no reason for this not to work.  First $(h 'x) is run,
 yielding code <blah> that is spliced instead of the $(h 'x). Then (g
 <blah>) is typechecked and run, yielding code that replaces the
 $(g ...) splice.  
 
 So this simply lifts the restriction.
 
 Fix Trac #3467: non-top-level type splices
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 It appears that when I added the ability to splice types in TH
 programs, I failed to pay attention to non-top-level splices -- that
 is, splices inside quotatation brackets.  
 
 This patch fixes the problem.  I had to modify HsType, so there's a
 knock-on change to Haddock.
 
 Its seems that a lot of lines of code has changed, but almost all the
 new lines are comments!
 
 General tidying up
 ~~~~~~~~~~~~~~~~~~
 As a result of thinking all this out I re-jigged the data type ThStage,
 which had far too many values before.  And I wrote a nice state transition
 diagram to make it all precise; 
    see Note [Template Haskell state diagram] in TcSplice
 
 Lots more refactoring in TcSplice, resulting in significantly less code.
 (A few more lines, but actually less code -- the rest is comments.)
 
 I think the result is significantly cleaner.

  - Fix the shadowing behaviour: if we end up with
    two packages with the same name/version that came from
    different package databases, then one will shadow the
    other.  This may mean we have to disable other packages
    that depended on the now-shadowed package.  Lots of

 A fine bug report (#3403) demonstrated that we were losing the tail
 call property when a complicated pattern match was involved.  After
 a bit of investigation I discovered that the culprit was the failure
 join-point introduced by the pattern matcher.  It was a zero-argument
 thunk, which is not very CPR-friendly, and that interacted badly with
 CPR worker/wrapper.
 
 It's easy to fix, the same way that we fix other join points, by supplying
 a dummy argument (that is not really passed at runtime.

 This has no effect with static libraries, but when the RTS is in a

  - internal calls to the function can use the faster non-PLT calls,

       * -r <repo>, specifies the remote repository darcs commands will use
   
   Some example commands:
   
   Get the libraries from a repository of your choosing. This is useful
   when working with a git mirror:
   
       $ ./darcs-all -r http://darcs.haskell.org get
   
   Pull changes. Used to be:

 This is needed both for per-session parallelism and for allowing

 atomicModifyIORef and unsafePerformIO it is also quite fast--an MVar

 branch it was about 1-2 percent slower, but then overall compilation
 times varied by about 4 percent, so I think it's worth it.

 'lilac' helpful pin-pointed a space leak that was due to a specialised
 function being insufficiently strict.  Here's the new comment in SpecConstr:
 
 Note [Transfer strictness]
 ~~~~~~~~~~~~~~~~~~~~~~~~~~
 We must transfer strictness information from the original function to
 the specialised one.  Suppose, for example
 
   f has strictness     SS
         and a RULE     f (a:as) b = f_spec a as b
 
 Now we want f_spec to have strictess  LLS, otherwise we'll use call-by-need
 when calling f_spec instead of call-by-value.  And that can result in 
 unbounded worsening in space (cf the classic foldl vs foldl')
 
 See Trac #3437 for a good example.
 
 The function calcSpecStrictness performs the calculation.

 It is possible for the program to allocate single object larger than a
 block, without going through the normal large-object mechanisms that
 we have for arrays and threads and so on.  
 
 The GC was assuming that no object was larger than a block, but #3424
 contains a program that breaks the assumption.  This patch removes the
 assumption.  The objects in question will still be copied, that is
 they don't get the normal large-object treatment, but this case is
 unlikely to occur often in practice.
 
 In the future we may improve things by generating code to allocate
 them as large objects in the first place.

 * Make C { A.a } work with punning, expanding to C { A.a = a }
 
 * Make it so that, with -fwarn-unused-matches, 
         f (C {..}) = x
   does not complain about the bindings introduced by the "..".
 
 * Make -XRecordWildCards implies -XDisambiguateRecordFields.
 
 * Overall refactoring of RnPat, which had become very crufty. 
   In particular, there is now a monad, CpsRn, private to RnPat,
   which deals with the cps-style plumbing.  This is why so many
   lines of RnPat have changed.
 
 * Refactor the treatment of renaming of record fields into two passes
        - rnHsRecFields1, used both for patterns and expressions,
             which expands puns, wild-cards
        - a local renamer in RnPat for fields in patterns
        - a local renamer in RnExpr for fields in construction and update
   This make it all MUCH easier to understand
  
 * Improve documentation of record puns, wildcards, and disambiguation

[Remove the lock around NameCache for readBinIface.
Thomas Schilling <nominolo@googlemail.com>**20090818213243
 
 Turns out using atomic update instead of a full-blown lock was easier
 than I thought.  It should also be safe in the case where we
 concurrently read the same interface file.  Whichever thread loses the
 race will simply find that all of the names are already defined and
 will have no effect on the name cache.

Simon Marlow <marlowsd@gmail.com>**20090818112942
 Ignore-this: c6f47c6bd3b12ecbd7aa3cfcd25bf9a7
 
 There were two bugs, and had it not been for the first one we would
 not have noticed the second one, so this is quite fortunate.
 
 The first bug is in stg_unblockAsyncExceptionszh_ret, when we found a
 pending exception to raise, but don't end up raising it, there was a
 missing adjustment to the stack pointer.  
 
 The second bug was that this case was actually happening at all: it
 ought to be incredibly rare, because the pending exception thread
 would have to be killed between us finding it and attempting to raise
 the exception.  This made me suspicious.  It turned out that there was
 a race condition on the tso->flags field; multiple threads were
 updating this bitmask field non-atomically (one of the bits is the
 dirty-bit for the generational GC).  The fix is to move the dirty bit
 into its own field of the TSO, making the TSO one word larger (sadly).

[Make the dynamic linker thread-safe.
Thomas Schilling <nominolo@googlemail.com>**20090817142352
   
 The current implementation is rather pessimistic.  The persistent
 linker state is now an MVar and all exported Linker functions are
 wrapped in modifyMVar calls.  This is serves as a big lock around all
 linker functions.
 
 There might be a chance for more concurrency in a few places. E.g.,
 extending the closure environment and loading packages might be
 independent in some cases.  But for now it's better to be on the safe
 side.

[Make access to NameCache atomic.  Sometimes needs a lock.
Thomas Schilling <nominolo@googlemail.com>**20090817004819
 
 'readBinIface' updates the name cache in a way that is hard to use
 with atomicModifyIORef, so this patch introduces a lock for this case.
 All other updates use atomicModifyIORef.
 
 Having a single lock is quite pessimistic, so it remains to be seen
 whether this will become a problem.  In principle we only need to make
 sure that we do not load the same file concurrently (or that it's
 idempotent).  In practice we also need to ensure that concurrent reads
 do not cancel each other out (since the new NameCache may be based on
 an outdated version).

[Make updates to the Finder caches atomic.  Well, almost.

[Only look up whether a module's SOURCE-imported if it's in the current package
Ian Lynagh <igloo@earth.li>**20090813162435
 Suppose we import anotherPackage:M, which exports things from

 anotherPackage:Internal.hi.
 
 However, if we have also SOURCE-imported thisPackage:Internal then
 we don't want GHC to try to read anotherPackage:Internal.hi-boot
 instead.
 
 The mapping that tells us whether a module is SOURCE-imported uses just
 the module name for the key, so we have to check the package ID before
 looking it up.

[RTS tidyup sweep, first phase

 Ignore-this: 1f7aabac4d5f9d32f6d91f1ccb1a80a4
 
 The first phase of this tidyup is focussed on the header files, and in
 particular making sure we are exposinng publicly exactly what we need
 to, and no more.
 
  - Rts.h now includes everything that the RTS exposes publicly,
    rather than a random subset of it.
 
  - Most of the public header files have moved into subdirectories, and
    many of them have been renamed.  But clients should not need to
    include any of the other headers directly, just #include the main
    public headers: Rts.h, HsFFI.h, RtsAPI.h.
 
  - All the headers needed for via-C compilation have moved into the
    stg subdirectory, which is self-contained.  Most of the headers for
    the rest of the RTS APIs have moved into the rts subdirectory.
 
  - I left MachDeps.h where it is, because it is so widely used in
    Haskell code.
  
  - I left a deprecated stub for RtsFlags.h in place.  The flag
    structures are now exposed by Rts.h.
 
  - Various internal APIs are no longer exposed by public header files.
 
  - Various bits of dead code and declarations have been removed
 
  - More gcc warnings are turned on, and the RTS code is more
    warning-clean.
 
  - More source files #include "PosixSource.h", and hence only use
    standard POSIX (1003.1c-1995) interfaces.
 
 There is a lot more tidying up still to do, this is just the first
 pass.  I also intend to standardise the names for external RTS APIs
 (e.g use the rts_ prefix consistently), and declare the internal APIs
 as hidden for shared libraries.

 Contributed by: seliopou@gmail.com
     
 This patch modifies darcs-all to have feature parity with push-all by
 recognizing two new options.
 
     * -i, equivalent to --ignore-failure in push-all
     * -r <repo>, specifies the remote repository darcs commands will use
 
 Some example commands:
 
 Get the libraries from a repository of your choosing. This is useful
 when working with a git mirror:
 
     $ ./darcs-all -r http://darcs.haskell.org get
 
 Pull changes. Used to be:
 
     $ ./push-all --pull http://darcs.haskell.org
 
 Is now:
 
     $ ./darcs-all -r http://darcs.haskell.org pull
 
 Or to use the default remote of the ghc repository:

 In standalone deriving, we now do *not* check side conditions.
 We simply generate the code and typecheck it.  If there's a type
 error, it's the programmer's problem. 
 
 This means that you can do 'deriving instance Show (T a)', where
 T is a GADT, for example, provided of course that the boilerplate
 code does in fact typecheck.
 
 I put some work into getting a decent error message.  In particular
 if there's a type error in a method, GHC will show the entire code
 for that method (since, after all, the user did not write it).
 Most of the changes are to achieve that goal.
 
 Still to come: changes in the documentation.

 Now, for a compiler-generated binding "x", if "x" is referred to by
 the exported "f", then it will be named "f_x" rather than something
 like "x23".  This means that hopefully
 
   - compilation will more often product the same results given the
     same input (the choice of names is not dependent on the
     non-deterministic order of bindings within the compiler).
 
   - less recompilation will be necessary after making changes
 
   - navigating Core might be a bit easier.
 
 unfortunately, compilation with -O still does not consistently produce
 the same ABI.  The simplifier sometimes does different things,
 apparently.

[Use names like '$fOrdInt' for dfuns (and TF instances), rather than '$f21'
Simon Marlow <marlowsd@gmail.com>**20090716125643
 Ignore-this: d0b4632cf8ed9e05b67a19aa19ab3e19
 
 2 reasons for this:
   - compilation is more predictable.  Adding or removing an instance
     is less likely to force unnecessary recompilation due to
     renumbering other dfun names.
   - it makes it easier to read Core / C-- / asm
 
 The names aren't completely deterministic.  To do that, we'd have to
 include package and module names, which would make the symbol names
 long and reduce readability.  So the compromise is that if there's a
 clash, we disambiguate by adding an integer suffix.  This is fairly
 unlikely in practice unless you're using overlapping instances.
 
 Type family instances are handled in the same way, with the same
 disambiguation strategy.

[New syntax for GADT-style record declarations, and associated refactoring
simonpj@microsoft.com**20090702094657
 Ignore-this: bd9817230d3773b3b01fae3d7f04c57d
 
 The main purpose of this patch is to fix Trac #3306, by fleshing out the
 syntax for GADT-style record declraations so that you have a context in 
 the type.  The new form is
    data T a where
      MkT :: forall a. Eq a => { x,y :: !a } -> T a
 See discussion on the Trac ticket.
 
 The old form is still allowed, but give a deprecation warning.
 
 When we remove the old form we'll also get rid of the one reduce/reduce
 error in the grammar. Hurrah!
 
 While I was at it, I failed as usual to resist the temptation to do lots of
 refactoring.  The parsing of data/type declarations is now much simpler and
 more uniform.  Less code, less chance of errors, and more functionality.
 Took longer than I planned, though.
 
 ConDecl has record syntax, but it was not being used consistently, so I
 pushed that through the compiler.
