2010-10-13bufio: bulletproof UnreadRuneRob Pike
After a fill(), there is nothing to back up. Make sure UnreadRune recognizes the situation. Fixes #1137. (Stops the crash, but doesn't make UnreadRune usable after a Peek()). R=rsc CC=golang-dev https://golang.org/cl/2498041

2010-10-13various: avoid %ld etcRuss Cox
The Plan 9 tools assume that long is 32 bits. We converted all instances of long to int32 when importing the code but missed the print formats. Because int32 is always int on the compilers we use, it is never correct to use %lux, %ld, etc. Convert to %ux, %d, etc. (It matters because on 64-bit gcc, long is 64 bits, so we were printing 32-bit quantities with 64-bit formats.)

2010-10-135l, 6l, 8l: first pass cleanupRuss Cox
* Maintain Sym* list for text with individual prog lists instead of using one huge list and overloading p->pcond. * Comment what each file is for. * Move some output code from span.c to asm.c. * Move profiling into prof.c, symbol table into symtab.c. * Move mkfwd to ld/lib.c. * Throw away dhog dynamic loading code. * Throw away Alef become. * Fix printing of WORD instructions in 5l -a. Goal here is to be able to handle each piece of text or data as a separate piece, both to make it easier to load the occasional .o file and also to make it possible to split the work across multiple threads.

Use a bytes.Buffer in log writing instead of string concatenation. Should reduce the number of allocations significantly. R=rsc, r2 CC=golang-dev https://golang.org/cl/2417042

2010-10-126l: work with OS X nm/otoolJim McGrath
6l was skipping emitting the (2 byte) symbol table if there were no imported or exported symbols. You can't just drop the symbol table entirely - the linker dies if you have a linkedit section but no table. You can omit the linkedit section or both the linkedit and the dlyd parts in the right circumstances, but that seems much more risky to me. R=rsc CC=golang-dev https://golang.org/cl/2421042
2010-10-12log: new interfaceRob Pike
New logging interface simplifies and generalizes. 1) Loggers now have only one output. 2) log.Stdout, Stderr, Crash and friends are gone. Logging is now always to standard error by default. 3) log.Panic* replaces log.Crash*. 4) Exiting and panicking are not part of the logger's state; instead the functions Exit* and Panic* simply call Exit or panic after printing. 5) There is now one 'standard logger'. Instead of calling Stderr, use Print etc. There are now triples, by analogy with fmt: Print, Println, Printf What was log.Stderr is now best represented by log.Println, since there are now separate Print and Println functions (and methods). 6) New functions SetOutput, SetFlags, and SetPrefix allow global editing of the standard logger's properties. This is new functionality. For instance, one can call log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds) to get all logging output to show file name, line number, and time stamp. In short, for most purposes log.Stderr -> log.Println or log.Print log.Stderrf -> log.Printf log.Crash -> log.Panicln or log.Panic log.Crashf -> log.Panicf log.Exit -> log.Exitln or log.Exit log.Exitf -> log.Exitf (no change) This has a slight breakage: since loggers now write only to one output, existing calls to log.New() need to delete the second argument. Also, custom loggers with exit or panic properties will need to be reworked. All package code updated to new interface. The test has been reworked somewhat. The old interface will be removed after the new release. For now, its elements are marked 'deprecated' in their comments. Fixes #1184. R=rsc CC=golang-dev https://golang.org/cl/2419042

Package iterable has outlived its utility. It is an interesting demonstration, but it encourages people to use iteration over channels where simple iteration over array indices or a linked list would be cheaper, simpler, and have fewer races.

2010-10-11new command gotry.Rob Pike
An exercise in reflection and an unusual tool. From the usage message: usage: gotry [packagedirectory] expression ... Given one expression, gotry attempts to evaluate that expression. Given multiple expressions, gotry treats them as a list of arguments and result values and attempts to find a function in the package that, given the first few expressions as arguments, evaluates to the remaining expressions as results. If the first expression has methods, it will also search for applicable methods. If there are multiple expressions, a package directory must be specified. If there is a package argument, the expressions are evaluated in an environment that includes import . "packagedirectory" Examples: gotry 3+4 # evaluates to 7 gotry strings '"abc"' '"c"' 7-5 # finds strings.Index etc. gotry regexp 'MustCompile("^[0-9]+")' '"12345"' true # finds Regexp.MatchString R=rsc, PeterGo, r2 CC=golang-dev https://golang.org/cl/2352043
