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-6.6
|
|
=========
|
|
|
|
The 73rd release of NuttX, Version 6.6, was made on July 11, 2011
|
|
and is available for download from the SourceForge website. The
|
|
6.6 release adds several smaller features but is mostly a bugfix
|
|
release.
|
|
|
|
Bugfixes include
|
|
|
|
* Fixed several NX Graphics bugs: Rendering fonts at >8 bits-per-pixel,
|
|
graphics move logic, and display artifacts that appear when a
|
|
window is closed.
|
|
* Corrections to the USB host mass storage class driver
|
|
* STM32 bugfixes: serial driver, GPIO interrupt handling
|
|
* LPC17xx: Changes for a success compilation with no console.
|
|
* Corrections to the Teensy AT90USB SD driver
|
|
* Changes for a clean compilation under the ZDS-II toolchain.
|
|
|
|
Minor features:
|
|
|
|
* Add logic to extract printf strings from FLASH (but there are
|
|
still printf issues for that target)
|
|
* Added a configuration for the Sure Electronics PIC32MX board.
|
|
However, higher priority tasks have stopped work on that
|
|
configuration.
|
|
* Added several new configurations for the STMicro STM3210E-EVAL
|
|
board.
|
|
* Added support for the STM3210E-EVAL board: (1) LCD in either
|
|
landscape or portrait mode, and (2) interrupting buttons.
|
|
* Added a configuration option to use different serial ports for
|
|
debug and for the NSH serial console (there are some issues
|
|
with CR-LF expansion and character echo if NSH is not run on
|
|
the console).
|
|
* Standardized the button press and button interrupt interfaces
|
|
so that they are common across all boards.
|
|
* Added a new graphics example that focuses on placing text on
|
|
the background while pop-up windows occur. Text should continue
|
|
to update normally with or without the popup windows present.
|
|
* Added ARM stack checking logic.
|
