2012-01-15exp/ssh: remove duplicated terminal code.Adam Langley
The terminal code in exp/terminal was forked from the code in exp/ssh. This change removes the duplicated code from exp/ssh in favour of using exp/terminal. R=rsc CC=golang-dev https://golang.org/cl/5375064

2012-01-15net: platform-dependent default socket optionsMikio Hara
This CL revises existing platform-dependent default socket options to make it possible to accomodate multiple multicast datagram listeners on a single service port. Also removes unnecessary SO_REUSEADDR, SO_REUSEPORT socket options from unicast datagram sockets by default. Fixes #1692. R=devon.odell, alex.brainman, rsc CC=golang-dev https://golang.org/cl/5538052

2012-01-14exp/terminal: add SetPrompt and handle large pastes.Adam Langley
(This was missing in the last change because I uploaded it from the wrong machine.) Large pastes previously misbehaved because the code tried reading from the terminal before checking whether an line was already buffered. Large pastes can cause multiples lines to be read at once from the terminal. R=bradfitz CC=golang-dev https://golang.org/cl/5542049
2012-01-14exp/proxy: new packageAdam Langley
exp/proxy provides client support for tunneling connections through various proxies. This is an initial, incomplete sketch of the code to lay down an API. R=golang-dev, r, r, bradfitz, rsc CC=golang-dev https://golang.org/cl/5490062

2012-01-13godoc: make ?m=src mode deterministicRobert Griesemer
Merge package files in the go/ast MergePackageFiles function always in the same order (sorted by filename) instead of map iteration order to obtain the same package file each time. This functionality is used by godoc when displaying packages in ?m=src mode. Also: minor cleanup in godoc.go. R=rsc CC=golang-dev https://golang.org/cl/5540054
2012-01-13xml: major Go 1 fixupGustavo Niemeyer
This CL improves the xml package in the following ways: - makes its interface match established conventions - brings Marshal and Unmarshal closer together - fixes a large number of bugs and adds tests - improves speed significantly - organizes and simplifies the code Fixes #2426. Fixes #2406. Fixes #1989. What follows is a detailed list of those changes. - All matching is case sensitive without special processing to the field name or xml tag in an attempt to match them. Customize the field tag as desired to match the correct XML elements. - Flags are ",flag" rather than "flag". The names "attr", "chardata", etc, may be used to name actual XML elements. - Overriding of attribute names is possible with "name,attr". - Attribute fields are marshalled properly if they have non-string types. Previously they were unmarshalled, but were ignored at marshalling time. - Comment fields tagged with ",comment" are marshalled properly, rather than being marshalled as normal fields. - The handling of the Any field has been replaced by the ",any" flag to avoid unexpected results when using the field name for other purposes, and has also been fixed to interact properly with name paths. Previously the feature would not function if any field in the type had a name path in its tag. - Embedded struct support fixed and cleaned so it works when marshalling and also when using field paths deeper than one level. - Conflict reporting on field names have been expanded to cover all fields. Previously it'd catch only conflicts of paths deeper than one level. Also interacts correctly with embedded structs now. - A trailing '>' is disallowed in xml tags. It used to be supported for removing the ambiguity between "attr" and "attr>", but the marshalling support for that was broken, and it's now unnecessary. Use "name" instead of "name>". - Fixed docs to point out that a XMLName doesn't have to be an xml.Name (e.g. a struct{} is a good fit too). The code was already working like that. - Fixed asymmetry in the precedence of XML element names between marshalling and unmarshalling. Marshal would consider the XMLName of the field type before the field tag, while unmarshalling would do the opposite. Now both respect the tag of the XMLName field first, and a nice error message is provided in case an attempt is made to name a field with its tag in a way that would conflict with the underlying type's XMLName field. - Do not marshal broken "<???>" tags when in doubt. Use the type name, and error out if that's not possible. - Do not break down unmarshalling if there's an interface{} field in a struct. - Significant speed boost due to caching of type metadata and overall allocation clean ups. The following timings reflect processing of the the atom test data: Old: BenchmarkMarshal 50000 48798 ns/op BenchmarkUnmarshal 5000 357174 ns/op New: BenchmarkMarshal 100000 19799 ns/op BenchmarkUnmarshal 10000 128525 ns/op R=cw, gustavo, kevlar, adg, rogpeppe, fullung, christoph, rsc CC=golang-dev https://golang.org/cl/5503078

Fixes godoc text mode (i.e., URL?m=text). R=golang-dev, adg CC=golang-dev https://golang.org/cl/5545043
2012-01-12go/doc: streamlined go/doc APIRobert Griesemer
- the main changes are removing the Doc suffix from the exported types, so instead of doc.TypeDoc one will have doc.Type, etc. - All exported types now have a Name (or Names) field. For Values, the Names field lists all declared variables or constants. - Methods have additional information about where they are coming from. - There's a mode field instead of a bool to control the package's operation, which makes it easier to extend w/o API changes. Except for the partially implemented new Method type, this is based on existing code. A clean rewrite is in progress based on this new API. R=rsc, kevlar CC=golang-dev https://golang.org/cl/5528060

2012-01-12go/parser: Remove unused Parse* functions. Simplified ParseExpr signature.Robert Griesemer
Only ParseFile, ParseDir, and ParseExpr are used in the tree. If partial parsing of code is required, it is fairly simple to wrap the relevant piece of code into a dummy package for parsing (see parser.ParseExpr). Also: minor cleanups. R=rsc CC=golang-dev https://golang.org/cl/5535055
2012-01-12go/ast: remove unnecessary result value from ast.Fprint/PrintRobert Griesemer
