File GitCompat.darcs-patch, 91.0 KB (added by guest, 9 years ago)

All fixes for Git compatability except .gitignore

1Wed Aug  6 22:02:07 BST 2008  Max Bolingbroke <batterseapower@hotmail.com>
2  * Prepare GHC for building with Git
3  * New packages format lets you select source control system in use
4  * Packages file now includes root repo explicitly
5  * Scripts darcs-all and push-all updated for the new packages format only
6  * New sync-all script, intended for use after Git changeover and for buildbots right now
7  * Had to remove libraries/bootstrapping from tree since Git cannot track empty directories without a hack
8  * Determine checkout date with Git using Darcs fallback in aclocal.m4

410 The flag is off by default, but GHCi turns it on (in Main.hs).  For
411 GHCi it can be overriden on the command-line or using :set.

415 GHC 6.9+ can properly handle cross-package recompilation checking, but
416 older versions of GHC couldn't, so in stage1 we always rebuild
417 Main.hs.  In other words, 'make' in ghc/ should do the right thing now.

585Simon Marlow <marlowsd@gmail.com>**20080729150518
586 This program contains an expression of the form
588    let x = snd (_, snd (_, snd (_, x)))
590 (probably not explicitly, but that's what appears in the heap at
591 runtime).  Obviously the program should deadlock if it ever enters
592 this thing, but apparently the test program in #2327 never does.
594 The GC tries to evaluate the snd closures, and gets confused due to
595 the loop.  In particular the earlier fix for #1038 was to blame.

600Simon Marlow <marlowsd@gmail.com>**20080728155621
601 When returning an unboxed tuple with a single non-void component, we
602 now use the same calling convention as for returning a value of the
603 same type as that component.  This means that the return convention
604 for IO now doesn't vary depending on the platform, which make some
605 parts of the RTS simpler, and fixes a problem I was having with making
606 the FFI work in unregisterised GHCi (the byte-code compiler makes
607 some assumptions about calling conventions to keep things simple).

990[#1205: ':load foo.hs' in GHCi always compiles to bytecode
991Simon Marlow <marlowsd@gmail.com>**20080709110830
993 So now
995   :load foo.hs       loads bytecode for foo.hs, even if foo.o exists
996   :load foo          is just shorthand for :load foo.hs
997   :load M            loads a module M, as object code if possible
998                      (no change here)
1000   :set -fobject-code
1001   :load foo.hs       loads foo.hs as object code; an existing foo.o
1002                      can be used.
1004 This turned out to be very straightforward: when building the
1005 ModSummary for a file (summariseFile) we just ignore the object file
1006 unless -fobject-code is on.
1008[add -fwarn-dodgy-foreign-imports (see #1357)
1009Simon Marlow <marlowsd@gmail.com>**20080709102143
1011 From the entry in the User's guide:
1013 -fwarn-dodgy-foreign-imports causes a warning to be emitted for
1014 foreign imports of the following form:
1016 foreign import "f" f :: FunPtr t
1018 on the grounds that it probably should be
1020 foreign import "&f" f :: FunPtr t
1022 The first form declares that `f` is a (pure) C function that takes no
1023 arguments and returns a pointer to a C function with type `t`, whereas
1024 the second form declares that `f` itself is a C function with type
1025 `t`.  The first declaration is usually a mistake, and one that is hard
1026 to debug because it results in a crash, hence this warning.
1028[Treat the Unicode "Letter, Other" class as lowercase letters (#1103)
1029Simon Marlow <marlowsd@gmail.com>**20080709091252
1030 This is an arbitrary choice, but it's strictly more useful than the
1031 current situation, where these characters cannot be used in
1032 identifiers at all.
1034 In Haskell' we may revisit this decision (it's on my list of things to
1035 discuss), but for now this is an improvement for those using caseless
1036 languages.
1038[FIX part of #2301, and #1619
1039Simon Marlow <marlowsd@gmail.com>**20080709084916
1041 2301: Control-C now causes the new exception (AsyncException
1042 UserInterrupt) to be raised in the main thread.  The signal handler
1043 is set up by GHC.TopHandler.runMainIO, and can be overriden in the
1044 usual way by installing a new signal handler.  The advantage is that
1045 now all programs will get a chance to clean up on ^C.
1047 When UserInterrupt is caught by the topmost handler, we now exit the
1048 program via kill(getpid(),SIGINT), which tells the parent process that
1049 we exited as a result of ^C, so the parent can take appropriate action
1050 (it might want to exit too, for example).
1052 One subtlety is that we have to use a weak reference to the ThreadId
1053 for the main thread, so that the signal handler doesn't prevent the
1054 main thread from being subject to deadlock detection.
1056 1619: we now ignore SIGPIPE by default.  Although POSIX says that a
1057 SIGPIPE should terminate the process by default, I wonder if this
1058 decision was made because many C applications failed to check the exit
1059 code from write().  In Haskell a failed write due to a closed pipe
1060 will generate an exception anyway, so the main difference is that we
1061 now get a useful error message instead of silent program termination.
1062 See #1619 for more discussion.

1097Simon Marlow <marlowsd@gmail.com>**20080707095836
1098 appendStringBuffer was completely bogus - the arguments to copyArray
1099 were the wrong way around, which meant that corruption was very likely
1100 to occur by overwriting the end of the buffer in the first argument.
1102 This definitely fixes #1736.  The other two bugs, #2169 and #2240 are
1103 harder to reproduce, but we can see how they could occur: in the case
1104 of #2169, the options parser is seeing the contents of an old buffer,
1105 and in the case of #2240, appendStringBuffer is corrupting an
1106 interface file in memory, since strng buffers and interface files are
1107 both allocated in the pinned region of memory.

1270[Several fixes to 'deriving' including Trac #2378
1273 This patch collects several related things together.
1275 * Refactor TcDeriv so that the InstInfo and the method bindings are renamed
1276   together.  This was messy before, and is cleaner now.  Fixes a bug caused
1277   by interaction between the "auxiliary bindings" (which were given
1278   Original names before), and stand-alone deriving (which meant that those
1279   Original names came from a different module). Now the names are purely
1280   local an ordinary.
1282   To do this, InstInfo is parameterised like much else HsSyn stuff.
1284 * Improve the location info in a dfun, which in turn improves location
1285   info for error messages, e.g. overlapping instances
1287 * Make sure that newtype-deriving isn't used for Typeable1 and friends.
1288   (Typeable was rightly taken care of, but not Typeable1,2, etc.)
1290 * Check for data types in deriving Data, so that you can't do, say,
1291        deriving instance Data (IO a)
1293 * Decorate the derived binding with location info from the *instance*
1294   rather than from the *tycon*.  Again, this really only matters with
1295   standalone deriving, but it makes a huge difference there.
1297 I think that's it.  Quite a few error messages change slightly.
1299 If we release 6.8.4, this should go in if possible.

1799Simon Marlow <simonmar@microsoft.com>**20071031144542
1801 Some objects don't need to be scavenged, in particular if they have no
1802 pointers.  This seems like an obvious optimisation, but in fact it
1803 only accounts for about 1% of objects (in GHC, for example), and the
1804 extra complication means it probably isn't worth doing.
1806[GC refactoring: change evac_gen to evac_step
1807Simon Marlow <simonmar@microsoft.com>**20071031144230
1809 By establishing an ordering on step pointers, we can simplify the test
1810   (stp->gen_no < evac_gen)
1811 to
1812   (stp < evac_step)
1813 which is common in evacuate().
1815[GC refactoring: make evacuate() take an StgClosure**
1816Simon Marlow <simonmar@microsoft.com>**20071031143634
1818 Change the type of evacuate() from
1819   StgClosure *evacuate(StgClosure *);
1820 to
1821   void evacuate(StgClosure **);
1823 So evacuate() itself writes the source pointer, rather than the
1824 caller.  This is slightly cleaner, and avoids a few memory writes:
1825 sometimes evacuate() doesn't move the object, and in these cases the
1826 source pointer doesn't need to be written.  It doesn't have a
1827 measurable impact on performance, though.

1835 minor GCs are still sequential. Don't use more threads than you
1836 have CPUs.
1838 It works most of the time, although you won't see much speedup yet.
1839 Tuning and more work on stability still required.
1841[Refactoring of the GC in preparation for parallel GC
1842Simon Marlow <simonmar@microsoft.com>**20071031125136
1844 This patch localises the state of the GC into a gc_thread structure,
1845 and reorganises the inner loop of the GC to scavenge one block at a
1846 time from global work lists in each "step".  The gc_thread structure
1847 has a "workspace" for each step, in which it collects evacuated
1848 objects until it has a full block to push out to the step's global
1849 list.  Details of the algorithm will be on the wiki in due course.
1851 At the moment, THREADED_RTS does not compile, but the single-threaded
1852 GC works (and is 10-20% slower than before).

1873 I'd forgotten to do this for types.

1883 This bug was somehow tickled by the new code for desugaring

1886 were getting processed by postInlineUnconditionally. But that was

2055[Fix Trac #2334: validity checking for type families
2058 When we deal with a family-instance declaration (TcTyClsDecls.tcFamInstDecl)
2059 we must check the TyCon for validity; for example, that a newtype has exactly
2060 one field.  That is done all-at-once for normal declarations, and had been
2061 forgotten altogether for families.
2063 I also refactored the interface to tcFamInstDecl1 slightly.
2066 A slightly separate matter: if there's an error in family instances
2067 (e.g. overlap) we get a confusing error message cascade if we attempt to
2068 deal with 'deriving' clauses too; this patch bales out earlier in that case.
2071 Another slightly separate matter: standalone deriving for family
2072 instances can legitimately have more specific types, just like normal
2073 data decls. For example
2075    data instance F [a] = ...
2076    deriving instance (Eq a, Eq b) => Eq (F [(a,b)])
2078 So tcLookupFamInstExact can a bit more forgiving than it was.

2096[Desugar multiple polymorphic bindings more intelligently
2099 Occasionally people write very large recursive groups of definitions.
2100 In general we desugar these to a single definition that binds tuple,
2101 plus lots of tuple selectors.  But that code has quadratic size, which
2102 can be bad.
2104 This patch adds a new case to the desugaring of bindings, for the
2105 situation where there are lots of polymorphic variables, but no
2106 dictionaries.  (Dictionaries force us into the general case.)
2108 See Note [Abstracting over tyvars only]. 
2110 The extra behaviour can be disabled with the (static) flag
2112        -fno-ds-multi-tyvar
2114 in case we want to experiment with switching it on or off.  There is
2115 essentially-zero effect on the nofib suite though.
2117 I was provoked into doing this by Trac #1136.  In fact I'm not sure
2118 it's the real cause of the problem there, but it's a good idea anyway.
2121[Add non-recursive let-bindings for types
2124 This patch adds to Core the ability to say
2125        let a = Int in <body>
2126 where 'a' is a type variable.  That is: a type-let.
2127 See Note [Type let] in CoreSyn.
2129 * The binding is always non-recursive
2130 * The simplifier immediately eliminates it by substitution
2132 So in effect a type-let is just a delayed substitution.  This is convenient
2133 in a couple of places in the desugarer, one existing (see the call to
2134 CoreTyn.mkTyBind in DsUtils), and one that's in the next upcoming patch.
2136 The first use in the desugarer was previously encoded as
2137        (/\a. <body>) Int
2138 rather that eagerly substituting, but that was horrid because Core Lint
2139 had do "know" that a=Int inside <body> else it would bleat.  Expressing
2140 it directly as a 'let' seems much nicer.
