2012-01-27gc: remove extra paranoia from inlining unsafe.Pointer fix.David Symonds

2012-01-27cmd/go: solve ambiguity of get lp.net/project/fooGustavo Niemeyer
This solves the ambiguity for "lp.net/project/foo". In these URLs, "foo" could be a series name registered in Launchpad with its own branch, and it could also be the name of a directory within the main project branch one level up. Solve it by testing if the series branch exists in Launchpad and if it doesn't moving the root one level up. R=rsc CC=golang-dev https://golang.org/cl/5577058

2012-01-26net/http: add Request.RequestURI fieldBrad Fitzpatrick
The new url.URL's parsing can be too canonicalizing for certain applications. By keeping the original request URI around, we give applications a gross escape hatch while keeping the URL package clean and simple for normal uses. (From a discussion with Gary Burd, Gustavo Niemeyer, and Russ Cox.) Fixes #2782 R=golang-dev, rsc, dsymonds CC=golang-dev https://golang.org/cl/5580044

2012-01-26godoc: move overview before API TOCRuss Cox
Compare: http://swtch.com/junk/regexp0.html [old] http://swtch.com/junk/regexp.html [new] Especially for packages with large APIs, this makes the overview more promiment, so that it can give the appropriate context for reading the API list. This should help significantly in packages with large APIs, like net, so that the first thing users see is not a jumble of functions but an introduction to the package.

2012-01-25cmd/goapi: new tool for tracking exported API over timeBrad Fitzpatrick
The idea is that we add files to the api/ directory which are sets of promises for the future. Each line in a file is a stand-alone feature description. When we do a release, we make sure we haven't broken or changed any lines from the past (only added them). We never change old files, only adding new ones.

2012-01-25go/doc: revert API change (per former discussion) and cleanupRobert Griesemer
Separating Method from Func made the code only more complicated without adding much to the useability/readability of the API. Reverted to where it was, but leaving the new method-specific fields Orig and Level. Former clients (godoc) of doc.Method only used the Func fields; and because Func was embedded, no changes are needed with respect to the removal of Method. Changed type of Func.Recv from ast.Expr to string. This was a long-standing TODO. Also implemented Func.Orig field (another TODO). No further go/doc API changes are expected for Go 1.

R=golang-dev, gri CC=golang-dev https://golang.org/cl/5577050
2012-01-25gofix: handle xml.Unmarshal in xmlapi fixGustavo Niemeyer
This improves the handling of xml.Unmarshal in the xmlapi fix by guessing some of the common types used on it. This also fixes a bug in the partial typechecker. In an expression such as f(&a), it'd mark a as having &T rather than *T. R=golang-dev, rsc CC=golang-dev https://golang.org/cl/5572058

2012-01-25gc: fix order of evaluationRuss Cox
Pulling function calls out to happen before the expression being evaluated was causing illegal reorderings even without inlining; with inlining it got worse. This CL adds a separate ordering pass to move things with a fixed order out of expressions and into the statement sequence, where they will not be reordered by walk. Replaces lvd's CL 5534079.
