build: use go command during build · 41a6165c

Russ Cox authored Dec 20, 2011

If something goes wrong, it should suffice to set
USE_GO_TOOL=false in env.bash to fall back to the
makefiles.  I will delete the makefiles in January.

cmd/go: work toward build script · fd1c1b96

Russ Cox authored Dec 20, 2011

The commands in the standard tree are now named
by the pseudo-import paths cmd/gofmt etc.
This avoids ambiguity between cmd/go's directory

gc: allow use of unsafe.Pointer in generated code · 82a6a4f3

Russ Cox authored Dec 20, 2011

The functions we generate to implement == on structs
or arrays may need to refer to unsafe.Pointer even in
safe mode, in order to handle unexported fields contained
in other packages' structs.

template: better error message for empty templates · 4869996b

Rob Pike authored Dec 20, 2011

New("x").ParseFiles("y") can result in an empty "x" template.
Make the message clearer that this is the problem. The error
returns from both template packages in this case were
confusing.

I considered making the method use "x" instead of "y" in
this case, but that just made other situations confusing
and harder to explain.

Fixes #2594.

testing: allow benchmarks to print and fail · c50e4f5e

Rob Pike authored Dec 20, 2011

Refactors the benchmarks and test code.
Now benchmarks can call Errorf, Fail, etc.,
and the runner will act accordingly.

Because functionality has been folded into an
embedded type, a number of methods' docs
no longer appear in godoc output. A fix is
underway; if it doesn't happen fast enough,
I'll add wrapper methods to restore the
documentation.

It uses extended floats with a 64-bit mantissa, but cannot give
an answer for all cases.

strconv: reduce buffer size for multi-precision decimals. · 3a2dec02

Rémy Oudompheng authored Dec 19, 2011

The longest numbers we have to represent are the smallest denormals.
Their decimal mantissa is not longer than 5^1100. Taking into
account some extra size for in-place operations, 800 digits are
enough. This saves time used for zero intiialization of extra
bytes.
