The documentation grew one page at a time, so the tree follows the
history of who wrote what and not the shape of NuttX. Scheduling is
spread over three places, a driver page can sit above the subsystem
that owns it, and the front page lists everything at the same level.
That is a lot to face when all you want to know is where the scheduler
lives.
This change files every page under the code it describes. It is a move,
not a rewrite: outside the ten pages named below, every page keeps the
text that is already in master, and no page's text is deleted.
What it does:
* Groups the table of contents into nine chapters.
* Moves the OS subsystems under os/: scheduling, memory, drivers,
filesystem, networking, IPC, interrupts, libs, time.
* Renames the platform pages to the names the source tree uses, and
derives their tags from the tree instead of by hand.
* Splits guides/ by subject.
* Adds Documentation/redirects.py, with a rule for every page that left
its old path, so old URLs keep working. The redirect page also carries
a link's #anchor across to the new page.
Ten pages have text that is new or rewritten. Nine of them are the
landing page of a chapter, which has to exist for the new structure:
index the front page
os/index OS Design
os/scheduling/index Scheduling
os/interrupts/index Interrupts
os/ipc/index IPC
os/time/index Time and timers
about/index About
developing/index Developing NuttX
ReleaseNotes/index Release notes
The tenth is os/libs/libbuiltin, the only page here with technical
content: libs/libbuiltin/ had no page at all. Five SVG diagrams come
with these pages, hand-written XML with no editor metadata.
Nothing outside Documentation/ is touched.
How it was checked:
* Sphinx builds with -W: no warnings, and no document left outside a
toctree.
* A script, offered in the PR, proves the narrow claim this rests on.
For every page outside the ten named above it erases what a move
touches -- link target, path, tag line, toctree block, table border --
from the whole old text and the whole new text, and requires the two
to be byte for byte identical. It also requires every sentence of a
deleted page to turn up somewhere, and every page that left its old
path to have a redirect, from a URL that existed, to where its content
went. It exits non-zero and names the page if any of that is not true,
and it tests added pages too, so forgetting to declare one cannot make
it pass.
* An independent audit checked 133 factual claims on these ten pages
against the tree, one shell command per claim: 130 confirmed, 1
refuted and fixed here, 2 not checkable.
* tools/checkpatch.sh is clean over the range.
The diff is large because moving a page changes every link that points
to it. Most of it is pure renames, and board pages that gained one tag
line.

NuttX-6.23
|
|
==========
|
|
|
|
The 90th release of NuttX, Version 6.23, was made on November 5, 2012,
|
|
and is available for download from the SourceForge website. Note
|
|
that release consists of two tarballs: nuttx-6.23.tar.gz and
|
|
apps-6.23.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|
|
file for build information).
|
|
|
|
This release corresponds with SVN release number: r5313
|
|
|
|
Note that all SVN information has been stripped from the tarballs. If you
|
|
need the SVN configuration, you should check out directly from SVN. Revision
|
|
r5313 should equivalent to release 6.23 of NuttX 6.23:
|
|
|
|
svn checkout -r5313 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
|
|
|
|
Or
|
|
|
|
svn checkout -r5313 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code
|
|
|
|
Additional new features and extended functionality:
|
|
|
|
* RTOS: If both atexit() and on_exit() are enabled, use on_exit() to
|
|
implement atexit(). Updates for RGMP 4.0.
|
|
|
|
* Binfmt: Add support for loading and executing ELF binary modules from
|
|
a file system.
|
|
|
|
* Drivers: Maxim MAX11802 touchscreen controller (Petteri Aimonen)
|
|
|
|
* STM32 Driver: Implementation of /dev/random using the STM32 Random Number
|
|
Generator (RNG).
|
|
|
|
* STM32 Boards: ADC support for the Shenzhou IV board. Relay support for
|
|
the Shenzhou IV board.
|
|
|
|
* C Library: Support is now included for the add-on uClibc++ C++
|
|
standard library support. This includes support for iostreams, strings,
|
|
STL, RTTI, exceptions -- the complete C++ environment. (uClibc++ is
|
|
provided as a separate add-on package due to licensing issues).
|
|
|
|
Optimized generic and ARM-specific memcpy() function. Optimized
|
|
memset() function.
|
|
|
|
Add support for ferror(), feof(), and clearerror(). Add support for
|
|
__cxa_atexit().
|
|
|
|
Math Library: Port of the math library from Rhombus OS by Nick Johnson
|
|
(Darcy Gong).
|
|
|
|
* Applications: New NSH commands: ifup, ifdown, urlencode, urldecode,
|
|
base64enc, bas64dec, md5 (Darcy Gong). Add support for NSH telnet login
|
|
(Darcy Gong). Enancements to NSH ping command to support pinging hosts
|
|
with very long round-trip times. Extensions to the ifconfig command
|
|
Darcy Gong),
|
|
|
|
Many extensions to the webclient/wget and DNS resolver logic from Darcy
|
|
Gong. JSON, Base64, URL encoding, and MD5 libraries contributed by Darcy
|
|
Gong.
|
|
|
|
New examples: ELF loader, JSON, wgetjson, cxxtest, relays.
|
|
|
|
Bugfixes (see the change log for details). Some of these are very important
|
|
(marked *critical*):
|
|
|
|
* Drivers: W25 SPI FLASH
|
|
|
|
* STM32 Drivers: ADC reset
|
|
|
|
* Graphics: Missing implementation of the blocked method (*critical*,
|
|
Petteri Aimonen).
|
|
|
|
* C Library: Floating point numbers in printf and related formatting functions
|
|
(Mike Smith), cf[get|set]speed() (Mike Smith)
|
|
|
|
As well as other, less critical bugs (see the ChangeLog for details)
