      image: add PixOffset methods; use them in image/draw and image/tiff. · af08cfa4
      Nigel Tao authored 
      image/draw benchmarks show <1% change for the fast paths.
The slow paths got worse by 1-4%, but they're the slow paths.
I don't care so much about them, and presumably compiler improvements
could claw it back.

IIUC 6g's inlining is enabled by default now.

      net: use NewTimer, not NewTicker, in fd_windows.go · 98af3880
      Brad Fitzpatrick authored 
      It works with NewTicker too, but is potentially a bit less efficient,
and reads wrong.

This is what happens when you TBR Windows changes, I guess.

      godoc: specify HTML page metadata with a JSON blob · 7cb21a79
      Andrew Gerrand authored 
      This allows HTML pages to specify arbitrary data in a header:

<!--{
        "Title": "The page title",
        ...
}-->

replacing the old style comments:

<!-- title The page title -->

      net: change SetTimeout to SetDeadline · b71883e9
      Brad Fitzpatrick authored 
      Previously, a timeout (in int64 nanoseconds) applied to a granularity
even smaller than one operation:  a 100 byte read with a 1 second timeout
could take 100 seconds, if the bytes all arrived on the network 1 second
apart.  This was confusing.

Rather than making the timeout granularity be per-Read/Write,
this CL makes callers set an absolute deadline (in time.Time)
after which operations will fail.  This makes it possible to
set deadlines at higher levels, without knowing exactly how
many read/write operations will happen in e.g. reading an HTTP
request.

Fixes #2723
