2010-02-06draw.Draw fast paths for a nil mask (and RGBA dst).Nigel Tao1-0/+50
Averaged times (in microseconds) for drawing an 800x600 rectangle are listed below. The summary is: around a 100x improvement. draw.Draw call times were typically linear in the number of pixels touched (i.e. drawing an 800x600 rectangle took 100x as much time as drawing an 80x60 rectangle). Before this change, there was only the general-but-slow code path. When drawing any src with a 50%-opaque mask: 237300 us When drawing any src with a nil mask: 50100 us After this change, the 50%-opaque mask case is unchanged. For an *image.RGBA dst and nil mask and... ...a uniform color (i.e. an image.ColorImage) src: 282 us ...another *image.RGBA src: 615 us. For the curious, an intermediate implementation detected the special cases but used simple nested for loops instead of the built-in copy function. The respective times (compared to 282 and 615 for the final implementation, or 50100 for the original) were 3110 and 3573. Times were measured with 8g/8l on my laptop. I haven't tried gccgo or other architectures. R=r, rsc CC=golang-dev http://codereview.appspot.com/201048
2010-02-04In draw.Draw, separate the source-point and mask-point.Nigel Tao2-56/+66

2010-01-27More steps towards tracking of identifier scopes.Robert Griesemer1-1/+1
- provide scope to parse functions; if non-nil, parser uses the scope to declare and lookup identifiers - resolve forward references where possible R=rsc CC=golang-dev http://codereview.appspot.com/194098
2010-01-15 Steps towards tracking scopes for identifiers.Robert Griesemer6-87/+38
- Identifiers refer now to the language entity (Object) that they denote. At the moment this is at best an approximation. - Initial data structures for language entities (Objects) and expression types (Type) independent of the actual type notations. - Initial support for declaring and looking up identifiers. - Updated various dependent files and added support functions. - Extensively tested to avoid breakage. This is an AST change. R=rsc CC=golang-dev, rog http://codereview.appspot.com/189080

2009-12-15 1) Change default gofmt default settings forRobert Griesemer58-6519/+6521
parsing and printing to new syntax. Use -oldparser to parse the old syntax, use -oldprinter to print the old syntax. 2) Change default gofmt formatting settings to use tabs for indentation only and to use spaces for alignment. This will make the code alignment insensitive to an editor's tabwidth. Use -spaces=false to use tabs for alignment. 3) Manually changed src/exp/parser/parser_test.go so that it doesn't try to parse the parser's source files using the old syntax (they have new syntax now). 4) gofmt -w src misc test/bench 2nd set of files.

2009-12-11Remove GOBIN in PATH dependency; don't assume cwd is $GOROOT/srcDevon H. O'Dell2-4/+7
This change removes the necessity to have GOBIN in $PATH, and also doesn't assume that the build is being run from $GOROOT/src. This is a minimal set of necessary changes to get Go to build happily from the FreeBSD ports collection. R=rsc CC=golang-dev http://codereview.appspot.com/171044 Committer: Russ Cox <rsc@golang.org>
2009-12-10New flags for gofmt:Robert Griesemer1-1/+1
- oldparser parse old syntax (required semicolons) - oldprinter print old syntax (required semicolons) By default, these flags are enabled for now. Setting -oldparser=false has no effect until go/parser is changed to accept the new syntax. Enabled exp/parser in Makefile; update dependent exp/eval. R=rsc http://codereview.appspot.com/174051

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia9-18/+18
the bash scripts and makefiles for building go didn't take into account the fact $GOROOT / $GOBIN could both be directories containing whitespaces, and was not possible to build it in such a situation. this commit adjusts the various makefiles/scripts to make it aware of that possibility, and now it builds successfully when using a path with whitespaces as well.

Meant as illustration of the Go pattern that is using goroutines and channels to handle exceptional situations. Note: There is no need for "Finally" since the "try block" (the function f supplied to Try) cannot do a Smalltalk-style non-local return and terminate the function surrounding Try.
