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-6.4
|
|
=========
|
|
|
|
The 71st release of NuttX, Version 6.4, was made on June 5, 2011
|
|
and is available for download from the SourceForge website. The
|
|
6.4 release includes several new features:
|
|
|
|
* A new, full-featured FTP client. This client may be used as a library
|
|
for automated FTP or via an FTP client shell. The FTP shell
|
|
supports the following commands: cd, chmod, get, help, idle,
|
|
login, ls, quit, mkdir, noop, put, pwd, rename, rhelp, rm,
|
|
rmdir, size, time, and up. A configuration is available for
|
|
the NXP LPC17xx to demonstrate this functionality.
|
|
* A functional C1101 wireless driver (contributed by Uros Platise)
|
|
* A PCI-based E1000 Ethernet driver (contributed by Yu Qiang)
|
|
* New C library functions: inet_addr() (contributed by Yu Qiang),
|
|
strndup(), asprintf()
|
|
* Reduced memory allocation overhead for MCUs with small heaps (<64K).
|
|
* fdopen() now works with socket descriptors allowing standard
|
|
buffered C functions to be used for network communications.
|
|
* The NSH ifconfig command can now be used to set or change the
|
|
IP address (contributed by Yu Qiang)
|
|
|
|
This release also includes some completed but untested functionality.
|
|
|
|
* The MicroChip PIC32MX port is now code complete and ready to
|
|
begin testing. Unfortunately, testing will be delayed due to
|
|
tool issues.
|
|
* Support for the NXP LPC315x MCUs.
|
|
|
|
Additional miscellaneous enhancements and bug fixes to task_delete(),
|
|
recvfrom(), and other changes as noted in the ChangeLog.
