2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia1-2/+2
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. Fixes issue 115. R=rsc, dsymonds1 http://codereview.appspot.com/157067 Committer: Russ Cox <rsc@golang.org>
2009-08-12convert low-level (used by testing) packages toRuss Cox1-55/+5
whole-package compilation. new Makefiles, tests now in separate package bytes flag fmt io math once os reflect strconv sync time utf8 delete import "xxx" in package xxx. inside package xxx, xxx is not declared anymore so s/xxx.//g delete file and package level forward declarations. note the new internal_test.go and sync and strconv to provide public access to internals during testing. the installed version of the package omits that file and thus does not open the internals to all clients.

2009-06-29io.StringBytes -> strings.BytesRuss Cox1-2/+4
io.ByteBuffer -> bytes.Buffer left io.ByteBuffer stub around for now, for protocol compiler. R=r OCL=30861 CL=30872
2009-06-09mv src/lib to src/pkgRob Pike1-0/+60
tests: all.bash passes, gobuild still works, godoc still works. R=rsc OCL=30096 CL=30102
