This gives about a 6% performance improvement to pidigits. Thanks to Russ for the suggestion. R=rsc, gri CC=golang-dev https://golang.org/cl/957041

There was a bug in makeN that caused lots of unnecessary allocations. Fixing this exposed a few bugs in other functions which worked when makeN allocated a new slice, but failed when it simply resized an existing slice. The result is a pretty big performance improvement. When running pidigits, here were the numbers I got on amd64: Before this change: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.09u 0.02s 2.11r gc pidigits 12.68u 0.04s 12.72r gc_B pidigits 12.71u 0.03s 12.75r After: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.09u 0.00s 2.10r gc pidigits 6.82u 0.00s 6.85r gc_B pidigits 6.55u 0.01s 6.59r R=rsc, gri CC=golang-dev https://golang.org/cl/953042 -

Due to page boundary rounding, the header would have been loaded as part of the text segment already, but this change placates the "paxctl" tool on so-called hardened Linux distributions (as if normal distributions weren't already hard enough to use). R=r CC=golang-dev https://golang.org/cl/954041

This yields a pretty significant performance boost to pidigits and there are still some improvements to be made. Here are my numbers: amd64 w/ bignum: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.10u 0.00s 2.10r gc pidigits 22.92u 0.02s 22.97r gc_B pidigits 22.62u 0.00s 22.65r amd64 w/ big: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.09u 0.02s 2.11r gc pidigits 12.68u 0.04s 12.72r gc_B pidigits 12.71u 0.03s 12.75r 386 w/ bignum: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.09u 0.00s 2.09r gc pidigits 44.30u 0.01s 44.35r gc_B pidigits 44.29u 0.03s 44.35r 386 w/ big: pidigits 10000 gcc -O2 pidigits.c -lgmp 2.10u 0.00s 2.10r gc pidigits 22.70u 0.06s 22.79r gc_B pidigits 22.80u 0.09s 22.91r R=rsc, gri CC=golang-dev https://golang.org/cl/881050 -

This results in a 10-20x size reduction per record. (from ~150kb to ~10kb) This revision has been pushed live, as I'm in the process of converting Log records to bz2-compresed CompressedLog records. I would have waited but we're running seriously low on space and it seemed like a sane (and reversible) move. R=rsc CC=golang-dev https://golang.org/cl/872048

SETSID does return an errno - any reason why it has been done this way in zsyscall_linux_* ? Otherwise it should be the same as darwin. From SETSID(2) on my Linux box: ERRORS On error, -1 is returned, and errno is set. Fixes #730 R=rsc CC=golang-dev https://golang.org/cl/878047

This is the first of probably four separate CLs for the new implementation of the json package. The scanner is the core of the new implementation. The other CLs would be the new decoder, the new encoder, and support for JSON streams. R=r CC=golang-dev https://golang.org/cl/802051

this is a version synthesized from rsc's, dean's and my versions. changes and updates: - embeds the retval script and pushes a new version to the device if needed - passes arguments correctly to the program on the device - export GOARCH, GOTRACEBACK and GOGC from the local environment to the device. - added times.out support to run-arm enabled a few tests that are now passing and moved the GOGC=off workaround to run-arm.

Also the command "godoc -src pkg_name method_name" will output the source code only for one method even if there are more of them with the same name in the same package.
