b40bd5efb7 exp/norm: implementation of decomposition and composing functionality.
forminfo.go:
- Wrappers for table data.
- Per Form dispatch table.
composition.go:
- reorderBuffer type.  Implements decomposition, reordering, and composition.
- Note: decompose and decomposeString fields in formInfo could be replaced by
  a pointer to the trie for the respective form.  The proposed design makes
  testing easier, though.
normalization.go:
- Temporarily added panic("not implemented") methods to make the tests run.
  These will be removed again with the next CL, which will introduce the
  implementation.

1d8f822c17 url: new package
This is just moving the URL code from package http into its own package,
which has been planned for a while.
Besides clarity, this also breaks a nascent dependency cycle the new template
package was about to introduce.

Add a gofix module, url, and use it to generate changes outside http and url.

Sadness about the churn, gladness about some of the naming improvements.

e3df71f50b exp/template: support field syntax on maps
While using exp/template in practice, the syntax for
indexing values using the "index" action was found to be
very inconvenient for frequent use when handling dynamic
data from maps such as the ones used with json and yaml,
that use a type like map[string]interface{}.

For these kinds of maps, the default handling of fields as
{{.Field}} makes the task of handling the several references
significantly more pleasant and elegant, and is equivalent
to what's currently done in the "template" package and in
other external packages (e.g. mustache).

Even with this change, the index action is still relevant
as it allows indexing maps in other scenarios where keys
wouldn't be valid field names.

e3f3a5411a exp/template: don't panic on range of nil interface
This avoids a non-obvious panic when range is used on a
nil interface, and fixes it by behaving as if the range
was empty.

The new behavior is equivalent to the outcome of iterating
on a nil map or slice, and is useful because it allows
generic structures such as used in json (map[string]interface{})
to behave correctly if a key generally set to a list or map
isn't present.

595e9d5034 exp/template/html: New package with a toy template transformation.
func Reverse(*Template) *Template
returns a template that produces the reverse of the original
for any input.

Changes outside exp/template/html include:
- Adding a getter for a template's FuncMap so that derived templates
  can inherit function definitions.
- Exported one node factory function, newIdentifier.
  Deriving tempaltes requires constructing new nodes, but I didn't
  export all of them because I think shallow copy functions might
  be more useful for this kind of work.
- Bugfix: Template's Name() method ignores the name field so
  template.New("foo") is a nil dereference instead of "foo".

Caveats: Reverse is a toy.  It is not UTF-8 safe, and does not
preserve order of calls to funcs in FuncMap.

For context, see http://groups.google.com/group/golang-nuts/browse_thread/thread/e8bc7c771aae3f20/b1ac41dc6f609b6e?lnk=gst

9c774c3f26 runtime: correct seh installation during callbacks
Every time we enter callback from Windows, it is
possible that go exception handler is not at the top
of per-thread exception handlers chain. So it needs
to be installed again. At this moment this is done
by replacing top SEH frame with SEH frame as at time
of syscall for the time of callback. This is incorrect,
because, if exception strike, we won't be able to call
any exception handlers installed inside syscall,
because they are not in the chain. This changes
procedure to add new SEH frame on top of existing
chain instead.

I also removed m sehframe field, because I don't
think it is needed. We use single global exception
handler everywhere.

9d7e39340d syscall: delay load of dll functions until they are called
Before this change, syscall package would load
all dlls used anywhere in the go tree on startup.
For example, this program:

package main

import "fmt"

func main() {
       fmt.Printf("Hello world\n")
}

would load these dlls

kernel32.dll
advapi32.dll
shell32.dll
wsock32.dll
ws2_32.dll
dnsapi.dll
iphlpapi.dll

Most of these dlls are network related and are not used
in this program. Now the same program loads only

kernel32.dll
shell32.dll

This decreases start times somewhat.

This also relaxes the rules of which dlls can be included
in the standard library. We could now include system calls
that are not available on all versions of Windows, because
we could decide if we should call them during runtime.

4e5086b993 runtime: improve Linux mutex
The implementation is hybrid active/passive spin/blocking mutex.
The design minimizes amount of context switches and futex calls.
The idea is that all critical sections in runtime are intentially
small, so pure blocking mutex behaves badly causing
a lot of context switches, thread parking/unparking and kernel calls.
Note that some synthetic benchmarks become somewhat slower,
that's due to increased contention on other data structures,
it should not affect programs that do any real work.

a65f4ccb89 image/tiff: Do not panic when RowsPerStrip is missing.
The RowsPerStrip tag is mandatory according to the spec. However,
Mac OS sometimes (?) omits it. I managed to create such an image
by applying "tiffutil -none" on a compressed image.

If RowsPerStrip is 0, there was a division by zero in the decoder.
Assume that the image is a single strip in this case.

This fix makes NaN less than anything else and adds NaN and (+-)Inf to
testcases.

17d9093bf2 undo CL 4808044 / 1bd754e69ce7
ServeMux depends on having a URL
in order to mux.  It might be that the right
fix is to have CONNECT handlers just not
look at URL.

http: do not parse req.URL for CONNECT

8cdee891d7 fmt: handle precision 0 format stings in standard way
The C-stdlib heritage of printf/fprintf/sprintf has two odd
aspects for precisions of zero with integers. First, the zero
can be specified in any of these ways, "%4.0d", "%.0d" and
"%.d" which was not previously supported here. Secondly, the
seemingly universal interpretation of precision for integers
is that precision==0 and value==0 means print nothing at all.
The code here now handles this for integers just as the code
in big/int.c does the same for the Int type. New tests are
added to fmt_test.go to verify these changes.

ba2e3af177 ld: remove overlap of ELF sections on dynamic binaries
The dynamic ELF sections were pointing to the proper data,
but that data was already owned by the rodata and text sections.
Some ELF references explicitly prohibit multiple sections from
owning the same data, and strip behaves accordingly.

The data for these sections was moved out and their ranges are
now owned by their respective sections.  This change makes strip
happy both with and without -s being provided at link time.

A test was added in debug/elf to ensure there are no regressions
on this area in the future.

Fixes #1242.
Fixes #2022.

This causes the child, if still writing, to get an error or

finish.

I was having.

d1d466f620 crypto/x509: prevent chain cycles in Verify
It's possible to include a self-signed root certificate as an
intermediate and push Verify into a loop.

I already had a test for this so I thought that it was ok, but it
turns out that the test was void because the Verisign root certificate
doesn't contain the "IsCA" flag and so it wasn't an acceptable
intermediate certificate for that reason.

dd2074c82a sync: improve Mutex to allow successive acquisitions
This implementation allows a goroutine to do successive acquisitions
of a mutex even if there are blocked goroutines.
Moreover, it allows a newcomer goroutine to acquire a mutex ahead of
blocked goroutines (that is, it does not enforce FIFO).
On implementation level it's achieved by separating waiter count and
locked flag.

25733a94fd reflect: support for struct tag use by multiple packages
Each package using struct field tags assumes that
it is the only package storing data in the tag.
This CL adds support in package reflect for sharing
tags between multiple packages.  In this scheme, the
tags must be of the form

        key:"value" key2:"value2"

(raw strings help when writing that tag in Go source).

reflect.StructField's Tag field now has type StructTag
(a string type), which has method Get(key string) string
that returns the associated value.

Clients of json and xml will need to be updated.
Code that says

        type T struct {
                X int "name"
        }

should become

        type T struct {
                X int `json:"name"`  // or `xml:"name"`
        }

Use govet to identify struct tags that need to be changed
to use the new syntax.

997c00f991 runtime: replace Semacquire/Semrelease implementation
1. The implementation uses distributed hash table of waitlists instead of a centralized one.
  It significantly improves scalability for uncontended semaphores.
2. The implementation provides wait-free fast-path for signalers.
3. The implementation uses less locks (1 lock/unlock instead of 5 for Semacquire).
4. runtime·ready() call is moved out of critical section.
5. Semacquire() does not call semwake().

abd50de296 xml: add Marshal and MarshalIndent
I have written up a Marshal and MarshalIndent pair that should
closely reflect the way that Unmarshal works.  I would love feedback
on making this code more accessible and efficient... I haven't used
reflecton on this scale before, so there is probably a lot of work
that can be done on that.

Some potentially controversial things:
- All tag names are lower-cased by default.
- Zero-valued struct values are skipped.
- No namespace prefix (o:tag, etc) mechanism is supplied.
- You are allowed to marshal non-struct values (even though unmarshal
  cannot handle them).
- A tag for a non-XMLName struct field that isn't "attr", "chardata",
  or "innerxml" is used as the name of the tag.  This could wreak
  havoc if you try to marshal a protobuf struct.
- The "innerxml" and "chardata" are inserted verbatim.  If you try to
  marshal something straight from unmarshal, the results could be
  unexpected (remove "innerxml" support from Marshal would be one
  possible solution).

Users of the Scan() infrastructure that employ ReadRune() rather than
Token() need a way to skip leading spaces and newlines as set by the
the parent, Fscan(), Fscanln, or Fscanf(). As the internal methods and
boolean flags are not exported, this new function was added here and
in the Int and Nat Scan() functions of the big package. (fmt.Rat did
not need change since it uses Token()) Also added Printf style format

5d4eea6a2f http: better handling of 0-length Request.Body
As rsc suggested after change 58a6bdac3d12 was committed, we
now read the first byte of Request.Body when the
Request.ContentLength is 0 to disambiguate between a truly
zero-length body and a body of unknown length where the user
didn't set the ContentLength field.

This was also causing the reverse proxy problem where incoming
requests (which always have a body, of private type http.body,
even for 0-lengthed requests) were being relayed to the http
Transport for fetching, which was serializing the request as a
chunked request (since ContentLength was 0 and Body was
non-nil)

grsec needs the FIXED flag to be provided to mmap, which
works now.  That said, when the allocation fails to be made
in the specific address, we're still given back a writable
page.  This change will unmap that page to avoid using
twice the amount of memory needed.

It'd also be pretty easy to avoid the extra system calls
once we detected that the flag is needed, but I'm not sure
if that edge case is worth the effort.

forkAndExecInChild as the file descriptor for the new child's
controlling terminal.

Necessary changes have been made to mkerrors.sh to generate defs for
TIOC*, though changes to its output files are not included here.
The changes made should support Linux, FreeBSD and Darwin, at least.

97a929aac9 fmt: catch panics from calls to String etc.
This change causes Print et al. to catch panics generated by
calls to String, GoString, and Format.  The panic is formatted
into the output stream as an error, but the program continues.
As a special case, if the argument was a nil pointer, the
result is just "<nil>", because that's almost certainly enough
information and handles the very common case of String
methods that don't guard against nil.

Scan does not want this change. Input must work; output can
be for debugging and it's nice to get output even when you
make a mistake.

6e9b1a78ff http: make Headers be source of truth
Previously Request and Response had redundant fields for
Referer, UserAgent, and cookies which caused confusion and
bugs.  It also didn't allow us to expand the package over
time, since the way to access fields would be in the Headers
one day and promoted to a field the next day.  That would be
hard to gofix, especially with code ranging over Headers.

After a discussion on the mail package's design with a similar
problem, we've designed to make the Headers be the source of
truth and add accessors instead.

Request:
change: Referer -> Referer()
change: UserAgent -> UserAgent()
change: Cookie -> Cookies()
new: Cookie(name) *Cookie
new: AddCookie(*Cookie)

Response:
change: Cookie -> Cookies()

Cookie:
new: String() string

Parser is a work in progress but can populate most of the

All the complicated Perl syntax is missing, as are various
important optimizations made during parsing to the
syntax tree.

The plan is that exp/regexp's API will mimic regexp,
and exp/regexp/syntax provides the parser directly
for programs that need it (and for implementing exp/regexp).

Once finished, exp/regexp will replace regexp.

9c436ab7dc http: fix handling of 0-lengthed http requests
Via Russ Ross' bug report on golang-nuts, it was not possible
to send an HTTP request with a zero length body with either a
Content-Length (it was stripped) or chunking (it wasn't set).

This means Go couldn't upload 0-length objects to Amazon S3.
(which aren't as silly as they might sound, as S3 objects can
have key/values associated with them, set in the headers)

Amazon further doesn't supported chunked uploads. (not Go's
problem, but we should be able to let users set an explicit
Content-Length, even if it's zero.)

To fix the ambiguity of an explicit zero Content-Length and
the Request struct's default zero value, users need to
explicit set TransferEncoding to []string{"identity"} to force
the Request.Write to include a Content-Length: 0.  identity is
in RFC 2616 but is ignored pretty much everywhere.  We don't
even then serialize it on the wire, since it's kinda useless,
except as an internal sentinel value.

The "identity" value is then documented, but most users can
ignore that because NewRequest now sets that.

And adds more tests.

"address space conflict: map() =" on amd64 Linux with kernel
version 2.6.32.8-grsec-2.1.14-modsign-xeon-64.
With this change, SysMap will use MAP_FIXED to allocate its desired
address space, after first calling mincore to check that there is
nothing else mapped there.

d5c45c541d big.nat: Improved speed of nat-to-string conversion
Three optimizations: First, special-case power of two bases
that partion a Word(), bases 2, 4, 16, and 256. These can
be moved directly from internal Word() storage to the output
without multiprecision operations. Next, same approach for
the other power-of-two bases, 8, 32, 64, and 128. These
don't fill a Word() evenly, so special handling is needed
for those cases where input spans the high-bits of one Word
and the low bis of the next one.  Finally, implement the
general case for others bases in 2 <= base <= 256 using
superbases, the largest power of base representable in a
Word(). For base ten, this is 9 digits and a superbase of
10^9 for 32-bit Words and 19 digits and 10^19 for 64-bit
compiles. This way we do just 1/9th or 1/19th of the expensive
multiprecision divisions, unpacking superdigits using fast
native machine arithmetic. The resulting code runs 7x to
800x the speed of the previous approach, depending on the
length of the number to be converted--longer is relatively
faster.

Also, extended the tests and benchmarks for string to nat
(scan()) and nat to string (string()) functions. A further
enhancement awaits the next CL to make general cases about
7x faster for long cases.

f2f3b8fa99 strconv: change Quote to be Unicode-friendly,
add QuoteToASCII.
The Quote and QuoteRune functions now let printable
runes (as defined by unicode.IsPrint) through.  When
true 7-bit clean stuff is necessary, there are now two
new functions: QuoteToASCII and QuoteRuneToASCII.

Printf("%q") uses Quote. To get the old behavior, it
will now be necessary to say
        Printf("%s", strconv.QuoteToASCII(s))
but that should rarely be necessary.

c281ddf1eb crypto: reorg, cleanup and add function for generating CRLs.
This change moves a number of common PKIX structures into
crypto/x509/pkix, from where x509, and ocsp can reference
them, saving duplication. It also removes x509/crl and merges it into
x509 and x509/pkix.

x509 is changed to take advantage of the big.Int support that now
exists in asn1. Because of this, the public/private key pair in
http/httptest/server.go had to be updated because it was serialised
with an old version of the code that didn't zero pad ASN.1 INTEGERs.

Start (and Run) deal with copying stdout, stdin,

io.Writers.

There are convenience methods to capture a command's
stdout and/or stderr.

Using the getaddrinfo order is only okay if we

Since the code does not do that, we must make

IPv4 address, even on IPv6 systems.  With the CL
applied, gotest fails in package net on OS X.

««« original CL description
net: name-based destination address selection

getaddrinfo() orders the addresses according to RFC 3484.

This means when IPv6 is working on a host we get results like:
    []string = {"2001:4810::110", "66.117.47.214"}

and when it's not working we get:
    []string = {"66.117.47.214", "2001:4810::110"}

thus can drop firstFavoriteAddr.

This also means /etc/gai.conf works on relevant systems.

There's also one brown-paper-bag fix in here. Previously I had the
conditional for the MDC hash check backwards: the code was checking
that the hash was *incorrect*. This was neatly counteracted by another
bug: it was hashing the ciphertext of the OCFB prefix, not the

50effb654c net: name-based destination address selection
getaddrinfo() orders the addresses according to RFC 3484.

This means when IPv6 is working on a host we get results like:
    []string = {"2001:4810::110", "66.117.47.214"}

and when it's not working we get:
    []string = {"66.117.47.214", "2001:4810::110"}

thus can drop firstFavoriteAddr.

This also means /etc/gai.conf works on relevant systems.

f18a4e9609 syscall : add ProcAttr field to pass an unescaped command line on windows
On windows, the command line is passed as a single null-terminated string. While the automatic parameter escaping done by syscall.StartProcess works fine with most Windows programs, some applications do their own custom parsing of the command line, in which case the automatic escaping becomes harmful.
This CL adds a new extra CmdLine field to syscall.ProcAttr that will be used as the raw/unescaped command line if not empty.
Fixes #1849.

463f478dbb filepath: Abs must always return a clean path
When I was first coding Abs, I wondered if people wouldn't
expect the path to be consistently clean, even if the path
passed in was already absolute.

CL 4524078 has a potential problem based on exactly that
assumption, so it feels like this behavior is indeed the
most useful and least surprising.
