misc/dashboard: cope with removed Package fields. · e6c5e2a3

David Symonds authored Apr 11, 2012

adg removed some now-unwanted fields in Package a while ago,
but there are still datastore entities with those fields,
so we must explicitly check for ErrFieldMismatch and ignore it.

crypto/tls: update how we create testing scripts. · 7247dcab

Adam Langley authored Apr 11, 2012

crypto/tls is tested, in part, by replaying recorded TLS connections
and checking that the bytes sent by the Go code haven't changed.

Previously we used GnuTLS's debug output and extracted the bytes of
the TLS connection using a Python script. That wasn't great, and I
think GnuTLS removed that level of debugging in a more current
release.

This change records the connection with Go code and adds a test for
ECDHE-AES clients generating using this method.

runtime: fix floating point exception on Plan 9 · 7056ec6b

Akshat Kumar authored Apr 10, 2012

Change 5660047 moved an FLDCW instruction
that disables invalid operand traps into
runtime·asminit, which is called from
runtime·mstart. Thus, runtime·check is being
called prior to setting the appropriate control bits,
which on any QNaN comparison will cause Plan 9
to take an invalid operand trap. This change loads
the control bits (for Plan 9) prior to runtime·check.
Ideally, this should be done before the QNaN checks
on any system, but possibly other kernels simply
don't ever trap on invalid operands.

6c, 6g, 6l: add MOVQL to make truncation explicit · e530d6a1

Russ Cox authored Apr 10, 2012

Without an explicit signal for a truncation, copy propagation
will sometimes propagate a 32-bit truncation and end up
overwriting uses of the original 64-bit value.

The case that arose in practice is in C but I believe
that the same could plausibly happen in Go.
The main reason we didn't run into the same in Go
is that I (perhaps incorrectly?) drop MOVL AX, AX
during gins, so the truncation was never generated, so
it didn't confuse the optimizer.

Fixes #1315.
Fixes #3488.

cmd/8c: fix store to complex uint64 ptr · 30bc5d7b

Russ Cox authored Apr 10, 2012

Assignment of a computed uint64 value to an
address derived with a function call was executing
the call after computing the value, which trashed
the value (held in registers).

long long *f(void) { return 0; }
void g(int x, int y) {
        *f() = (long long)x | (long long)y<<32;
}

Before:

(x.c:3)	TEXT	g+0(SB),(gok(71))
...
(x.c:4)	ORL	AX,DX
(x.c:4)	ORL	CX,BX
(x.c:4)	CALL	,f+0(SB)
(x.c:4)	MOVL	DX,(AX)
(x.c:4)	MOVL	BX,4(AX)

After:
(x.c:3)	TEXT	g+0(SB),(gok(71))
(x.c:4)	CALL	,f+0(SB)
...
(x.c:4)	ORL	CX,BX
(x.c:4)	ORL	DX,BP
(x.c:4)	MOVL	BX,(AX)
(x.c:4)	MOVL	BP,4(AX)

FTR, below are result with the empty prefetch function,
that is, single RET but no real prefetching.
It suggests that inlinable PREFETCH is worth pursuing.

time: in Format give buffer an initial capacity · c9529e02

Bobby Powers authored Apr 07, 2012

I have a small web server that simply sets several cookies
along with an expires header, and then returns.  In the
cpuprofile for a 200k request benchmark, time.Time.Format()
was showing up as 8.3% of cpu usage.  Giving the buffer an
inital capacity to avoid reallocs on append drops it down to
7.6%.

syscall: manually fix z* for NetBSD/amd64 · 559c191b

Benny Siegert authored Apr 06, 2012

Building go currently fails on NetBSD, thus the regeneration
scripts do not run correctly. With these changes, at least
the go_bootstrap tool builds correctly.

Stéphane Travostino authored Apr 05, 2012

The shouldEscape function did not correctly escape the reserved characters listed in RFC 3986 §2.2, breaking some strict web servers.
Fixes #3433.
