exp/template: A template can be in one set only. · 0f7a1951

Rob Pike authored Jul 21, 2011

This simplifies the API and makes it easier to make the template
invocation statically secure, at the cost of some minor flexibility.

html: parse misnested formatting tags according to the HTML5 spec. · 5a141064

Nigel Tao authored Jul 21, 2011

This is the "adoption agency" algorithm.

The test case input is "<a><p>X<a>Y</a>Z</p></a>". The correct parse is:
| <html>
|   <head>
|   <body>
|     <a>
|     <p>
|       <a>
|         "X"

runtime: improve performance of sync channels · 90f3cb13

Dmitriy Vyukov authored Jul 20, 2011

1. SudoG always contains a pointer to the element
(thus no variable size, and less copying).
2. chansend/chanrecv allocate SudoG on the stack.
3. Copying of elements and gorotuine notifications
are moved out of critical sections.

ld: remove overlap of ELF sections on dynamic binaries · ba2e3af1

Gustavo Niemeyer authored Jul 20, 2011

The dynamic ELF sections were pointing to the proper data,
but that data was already owned by the rodata and text sections.
Some ELF references explicitly prohibit multiple sections from
owning the same data, and strip behaves accordingly.

The data for these sections was moved out and their ranges are
now owned by their respective sections.  This change makes strip
happy both with and without -s being provided at link time.

A test was added in debug/elf to ensure there are no regressions
on this area in the future.

Fixes #1242.
Fixes #2022.

NOTE: Tested on Linux amd64/386/arm only.

runtime: make goc2c build on Plan 9 · b546f507

Lucio De Re authored Jul 19, 2011

pkg/runtime/Makefile:
. Adjusted so "goc2c.c" is built using the Plan 9 libraries.

pkg/runtime/goc2c.c:
. Added/subtracted #include headers to correspond to Plan 9
  toolkit.
. Changed fprintf(stderr,...)/exit() combinations to
  sysfatal() calls, adjusted the "%u" format to "%ud".
. Added exits(0) at the end of main().
. Made main() a void-returning function and removed the
  "return 0" at the end of it.

Tested on UBUNTU and Plan 9 only.
