ec5c475919 http: add Flusher type; remove Flush from ResponseWriter
The Flush functionality wasn't removed, but now you have
to test if your ResponseWriter is also a Flusher:

func ServeHTTP(rw http.ResponseWriter, req *http.Request) {
   if f, ok := rw.(http.Flusher); ok {
       f.Flush()
   }
}

3a95587e01 fmt: make ScanState.Token more general.
When writing custom scanners, I found that
Token itself was rarely useful, as I did not always
want to stop at white space. This change makes
it possible to stop at any class of characters
while reusing the buffer within State.
(also fix a bug in Token)

2c420ece67 http: change ResponseWriter.SetHeader(k,v) to Header() accessor
Caller code needs to change:

rw.SetHeader("Content-Type", "text/plain")
to:
rw.Header().Set("Content-Type", "text/plain")

This now permits returning multiple headers
with the same name using Add:

rw.Header().Add("Set-Cookie", "..")
rw.Header().Add("Set-Cookie", "..")

This patch also fixes serialization of headers, removing newline characters.

Fixes #488

f0ab14647a ld: preserve symbol sizes during data layout
Fixes the broken linux/amd64 build.
The symbol table, itself a symbol, was having
its size rounded up to the nearest word boundary.
If the rounding add >7 zero bytes then it confused
the debug/gosym symbol table parser.  So you've
got a 1/8 chance to hit the bug on an amd64 system.

Just started in the recent change because I fixed
the rounding to round to word boundary instead
of to 4-byte boundary.

7a09a88274 5l, 6l, 8l: omit symbols for type, string, go.string
Much of the bulk of Go binaries is the symbol tables,
which give a name to every C string, Go string,
and reflection type symbol.  These names are not worth
much other than seeing what's where in a binary.

This CL deletes all those names from the symbol table,
instead aggregating the symbols into contiguous blocks
and giving them the names "string.*", "go.string.*", and "type.*".

Before:
$ 6nm $(which godoc.old) | sort | grep ' string\.' | tail -10
  59eda4 D string."aa87ca22be8b05378eb1c71...
  59ee08 D string."b3312fa7e23ee7e4988e056...
  59ee6c D string."func(*token.FileSet, st...
  59eed0 D string."func(io.Writer, []uint8...
  59ef34 D string."func(*tls.Config, *tls....
  59ef98 D string."func(*bool, **template....
  59effc D string."method(p *printer.print...
  59f060 D string."method(S *scanner.Scann...
  59f12c D string."func(*struct { begin in...
  59f194 D string."method(ka *tls.ecdheRSA...
$

After:
$ 6nm $(which godoc) | sort | grep ' string\.' | tail -10
  5e6a30 D string.*
$

Those names in the "Before" are truncated for the CL.
In the real binary they are the complete string, up to
a certain length, or else a unique identifier.
The same applies to the type and go.string symbols.

Removing the names cuts godoc by more than half:

-rwxr-xr-x 1 rsc rsc 9153405 2011-03-07 23:19 godoc.old
-rwxr-xr-x 1 rsc rsc 4290071 2011-03-07 23:19 godoc

For what it's worth, only 80% of what's left gets loaded
into memory; the other 20% is dwarf debugging information
only ever accessed by gdb:

-rwxr-xr-x 1 rsc rsc 3397787 2011-03-07 23:19 godoc.nodwarf

021b040a1e go/ast, go/parser: populate identifier scopes at parse time
The parser populates all scopes for a given file (except
type-related scopes for structs, interfaces, and methods
of types) at parse time.

A new parser flag, DeclarationErrors, enables error messages
related to declaration errors (as far as it is possible to
provide them).

The resulting AST has all (non-field, non-method) identifiers
resolved that can be resolved w/o doing imports or parsing
missing package files.

The ast.File node contains the (partially complete)
package scope and a list of unresolved global identifiers.

All type-specific data structures have been removed from the AST.

The existing typechecker is functional but needs to be adjusted
(simplified) accordingly. Utility functions to resolve all
identifiers for a package (after handling imports and parsing
all package files) are  missing.

Unrelated changes:
- Rename typechecker/testdata files to that they are not considered
  by gofmt.
- Minor cleanups/simplifications.

Parses all .go files in src and misc without declaration errors.
Runs all tests. Changes do not affect gofmt output.

That followup CL missed the lines being deleted
in this CL, spotted by Petar.

        src/pkg/rpc/server.go \
        test/arm-pass.txt

confirms that these lines in server.go are the
only ones that were missed by the original followup.

f9ca3b5d5b runtime: scheduler, cgo reorganization
* Change use of m->g0 stack (aka scheduler stack).
* Provide runtime.mcall(f) to invoke f() on m->g0 stack.
* Replace scheduler loop entry with runtime.mcall(schedule).

Runtime.mcall eliminates the need for fake scheduler states that
exist just to run a bit of code on the m->g0 stack
(Grecovery, Gstackalloc).

The elimination of the scheduler as a loop that stops and
starts using gosave and gogo fixes a bad interaction with the
way cgo uses the m->g0 stack.  Cgo runs external (gcc-compiled)
C functions on that stack, and then when calling back into Go,
it sets m->g0->sched.sp below the added call frames, so that
other uses of m->g0's stack will not interfere with those frames.
Unfortunately, gogo (longjmp) back to the scheduler loop at
this point would end up running scheduler with the lower
sp, which no longer points at a valid stack frame for
a call to scheduler.  If scheduler then wrote any function call
arguments or local variables to where it expected the stack
frame to be, it would overwrite other data on the stack.
I realized this possibility while debugging a problem with
calling complex Go code in a Go -> C -> Go cgo callback.
This wasn't the bug I was looking for, it turns out, but I believe
it is a real bug nonetheless.  Switching to runtime.mcall, which
only adds new frames to the stack and never jumps into
functions running in existing ones, fixes this bug.

* Move cgo-related code out of proc.c into cgocall.c.
* Add very large comment describing cgo call sequences.
* Simpilify, regularize cgo function implementations and names.
* Add test suite as misc/cgo/test.

Now the Go -> C path calls cgocall, which calls asmcgocall,
and the C -> Go path calls cgocallback, which calls cgocallbackg.

The shuffling, which affects mainly the callback case, moves
most of the callback implementation to cgocallback running
on the m->curg stack (not the m->g0 scheduler stack) and
only while accounted for with $GOMAXPROCS (between calls
to exitsyscall and entersyscall).

The previous callback code did not block in startcgocallback's
approximation to exitsyscall, so if, say, the garbage collector
were running, it would still barge in and start doing things
like call malloc.  Similarly endcgocallback's approximation of
entersyscall did not call matchmg to kick off new OS threads
when necessary, which caused the bug in issue 1560.

Fixes #1560.
