- use an interface {Get()} - implement Get for maps, slices - for slices, retrieves the address of the end of the array, which will give the same value for every slice of the same array. R=rsc CC=golang-dev https://golang.org/cl/179129

2009-12-18runtime: fix race conditionAdam Langley
(Thanks to ken and rsc for pointing this out) rsc: ken pointed out that there's a race in the new one-lock-per-channel code. the issue is that if one goroutine has gone to sleep doing select { case <-c1: case <-c2: } and then two more goroutines try to send on c1 and c2 simultaneously, the way that the code makes sure only one wins is the selgen field manipulation in dequeue: // if sgp is stale, ignore it if(sgp->selgen != sgp->g->selgen) { //prints("INVALID PSEUDOG POINTER\n"); freesg(c, sgp); goto loop; } // invalidate any others sgp->g->selgen++; but because the global lock is gone both goroutines will be fiddling with sgp->g->selgen at the same time. This results in a 7% slowdown in the single threaded case for a ping-pong microbenchmark. Since the cas predominantly succeeds, adding a simple check first didn't make any difference.

2009-12-17Basic image/jpeg decoder.Nigel Tao
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 https://golang.org/cl/164056
