2009-12-17Basic image/jpeg decoder.Nigel Tao4-0/+785
This is not a complete JPEG implementation (e.g. it does not handle progressive JPEGs or restart markers), but I was able to take a photo with my phone, and view the resultant JPEG in pure Go. The decoder is simple, but slow. The Huffman decoder in particular should be easily improvable, but optimization is left to future changelists. Being able to inline functions in the inner loop should also help performance. The output is not pixel-for-pixel identical to libjpeg, although identical behavior isn't necessarily a goal, since JPEG is a lossy codec. There are at least two reasons for the discrepancy. First, the inverse DCT algorithm used is the same as Plan9's src/cmd/jpg, which has different rounding errors from libjpeg's default IDCT implementation. Note that libjpeg actually has three different IDCT implementations: one floating point, and two fixed point. Out of those four, Plan9's seemed the simplest to understand, partly because it has no #ifdef's or C macros. Second, for 4:2:2 or 4:2:0 chroma sampling, this implementation does nearest neighbor upsampling, compared to libjpeg's triangle filter (e.g. see h2v1_fancy_upsample in jdsample.c). The difference from the first reason is typically zero, but sometimes 1 (out of 256) in YCbCr space, or double that in RGB space. The difference from the second reason can be as large as 8/256 in YCbCr space, in regions of steep chroma gradients. Informal eyeballing suggests that the net difference is typically imperceptible, though. R=r CC=golang-dev, rsc http://codereview.appspot.com/164056
2009-12-151) Change default gofmt default settings forRobert Griesemer6-482/+482
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 3rd set of files.

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia2-4/+4
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.
