2010-04-20big: eliminate redundant array lookupsEvan Shaw1-5/+11
This gives about a 6% performance improvement to pidigits. Thanks to Russ for the suggestion. R=rsc, gri CC=golang-dev http://codereview.appspot.com/957041 Committer: Russ Cox <rsc@golang.org>
2010-04-20big: reduce the number of allocationsEvan Shaw1-4/+10
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 http://codereview.appspot.com/953042 Committer: Russ Cox <rsc@golang.org>

2010-04-206l, 8l: include ELF header in PT_LOAD mapping for text segmentRuss Cox2-10/+10
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).

2010-04-20big: Add Lsh and Value; convert pidigits to use bigEvan Shaw5-78/+239
This yields a pretty significant performance boost to pidigits and there are still some improvements to be made.

2010-04-20godashboard: bz2 compress logs in data storeAndrew Gerrand1-7/+10
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.

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.

2010-04-12fmt format verb %b bugAndrei Vieru3-9/+11
fmt.Printf("%b", int8(-1)) prints 64 ones instead of 8. This happens only for signed integers (int8, in16 and int32). I guess it's because of the way the conversion between integer types works. From go spec: "Conversions between integer types. If the value is a signed quantity, it is sign extended to implicit infinite precision ....". And there are several conversions to int64 and uint64 in the fmt package. This pathch solves only half of the problem. On a 32 bit system, an fmt.Printf("%b", int(-1)) should still print 64 ones.
