实在太快了。

哦,这个世界太疯狂。。。

On behalf of the NetBSD release engineering team, I'd like to announce
the beginning of the NetBSD 4.0 release process.  NetBSD 4.0 will be
the twelfth major release of the NetBSD Operating System.

As some of you may have noticed, NetBSD 4.0_BETA was branched on
August 8, 2006 (UTC), and the beta-testing process has officially begun.
It is expected that we will remain in beta until approximately
October 1, at which time the first Release Candidate will be tagged,
and binaries and ISO images will be made available within a few days.
New release candidates will be tagged approximately every two weeks
following, to address any critical bugs which may arise.  It is anticipated
that at least three Release Candidates will be required, putting the
approximate release date of NetBSD 4.0 around December 1.
PLEASE NOTE, this is independent of the release process for NetBSD 3.1,
which is also occurring during this time.

You can check the progress and status of the beta at:
http://www.netbsd.org/releng/releng-4.html

HOW YOU CAN HELP
----------------

Please test NetBSD 4.0_BETA on your hardware!  A lot of work has
gone into getting us this far, but we don't have access to every piece
of hardware out there.  If you've used previous releases of NetBSD,
please make sure all your devices continue to work; if you have
spare machines, please test the installation procedures.  With your
help, this will be the best release of NetBSD yet!

As always, problems should be reported using send-pr, or you may
use the web submission form at:=20

http://www.netbsd.org/cgi-bin/sendpr.cgi?gndb=3Dnetbsd

GETTING THE BETA
----------------

Getting source code via anonymous CVS:
--------------------------------------

To switch your existing tree to track NetBSD-4.0_BETA, use the "netbsd-4"
tag:

cd /usr/src
cvs update -rnetbsd-4 -dP

For more information about anonymous CVS, see
http://www.netbsd.org/Documentation/current/#using-anoncvs

Getting pre-built binaries:
---------------------------

The new netbsd-4 branch (which represents NetBSD 4.0_BETA) is being
periodically built by the NetBSD Foundation's autobuild cluster.
When all is working smoothly, it should be built two or three times
per week during the beta cycle.

You can access the latest autobuilds of NetBSD here:

http://releng.netbsd.org/cgi-bin/builds.cgi

and snapshots of NetBSD 4.0_BETA, in particular, can be found here:

ftp://ftp.netbsd.org/pub/NetBSD-daily/netbsd-4/

Please keep in mind that the autobuilds do fail for some platforms
occasionally, especially during the beta process.  If you don't see
a directory for your platform of choice for a given date, please try
another.  We will be keeping up to three autobuilds of NetBSD 4.0_BETA
around at any given time.

In order to make testing the beta easier, ISO images have been built
for the most recent 4.0_BETA autobuild.  They can be retrieved at:
ftp://ftp.netbsd.org/pub/NetBSD-daily/netbsd-4/200608230000Z/iso/ .

我就知道你会转过来。

也不算快了,3.0是去年12月RELEASE的,4.0按计划也是在12月。两个RELEASE相差1年。

并且,4.0是从2005年4月就开始分枝开发的,实际开发时间有1年8个月。

有没有计算机专业的来解读一下4.0有什么变化?
对于我来说,感觉最大的,一是gcc变成4.1了,二是sendmail彻底88了,三是build.sh可以制作syspkg和ISO了。

不是cross compiler,是系统里默认安装的gcc
3.x里的gcc仍然是3.3.3. 4.X系统里默认安装4.1.X了。

哦,呵呵,我一直用的src里面的gcc,所以没有注意系统默认的......
4.0还是要整点有用的东西进去才好啊,数字上去了不能表示功能也跟着上去了。最好能像FB的4.x到5.x或者Linux2.4 到2.6 那样,构架改动都不小。
用比较现代点的OS观点来看,NetBSD的内核是有点落后了。
要是NetBSD和DrangonflyBSD mix一下,出来的东西应该十分有趣。可惜Dfly BSD的说明性资料太少。

gcc 4.0默认时产生的代码还真不习惯。3.0的反汇编一步一步还知道怎么编译、怎么运行的,函数入口在那里。4.0产生的代码,反出来根本不知道编译器做了哪些优化,几个函数有时候优化到一起,连入口名都没有了,时常搞得我晕头转向
映像最深的是直接把编译器由3.0换到4.0,内核编译选项仍保留默认状态。有一次为了改变输出,需要追综sys/kern/subr_prf.c里面的printf,发现printf里调用的一个xxprintf的函数在4.0的汇编里面没有入口,最后单步调试才知道这个函数被优化兼并到一个大函数里去了 我以为是优化开关的问题,结果把-O调到0级还是如此......

不过,好像代码尺寸是小了那么一点点,呵呵。

我对硬件的很多东西都不熟悉,也看不出来NETBSD4.0到底增加了多少新功能。可能革命性的太少了吧,不像1.6到2.0那样振奋人心。

蓝牙技术的全面支持可能是4.0的亮点。可惜我至今还没用过任何相关设备……
MIDI这方面也大写特写。

另外一个有意思的东西,splash,可以自己定制启动画面。

提前把FB的TIMECOUNTER引入到4.0中(不太清楚TIMECOUNTER有什么用途)
