What about Web Stack?
Unlike Web Server which uses NSS for its SSL/TLS implementation, the various components in Web Stack use OpenSSL for the same purpose. Therefore, the state of the vulnerability for Web Stack components depend on whether OpenSSL has been updated to prevent the renegotiation attack (mostly).
The key is that Web Stack does not ship a private copy of OpenSSL - it uses the OpenSSL libraries present in the system. So it comes down to whether the system OpenSSL is vulnerable or not.
|Version||OpenSolaris||Solaris 10||Red Hat Linux|
|Web Stack 1.5 / OpenSolaris 2009.06||Safe only when openssl-0.9.8l shows up in release repo||Safe, once Sun Alert fixes are installed by user||Vulnerable, no relief available|
|Upcoming Web Stack 1.6 / OpenSolaris 2010.03||Safe (openssl-0.9.8l already in dev repo)||Safe, once Sun Alert fixes are installed by user||Vulnerable, no relief available|
|2007/12: 158 packages||2008/06: 205 packages||2009/02: 302 packages||2009/08: 416 packages||5000 package predictions|
|2.8 hours||3.6 hours||7.5 hours||9.7 hours||88,89,116,124|
|7.5 GB||10 GB||12.3 GB||19.4 GB||203,233,237,244|
The time/space predictions for 5000 packages are within the range previously seen (current one in bold in above table: 116 hours and 233GB) so no big surprises.
Well the big surprise is we're still building OpenSolaris applications this way!
For the Web Stack project and components we are now looking into dropping out of SFW since this is unsustainable and is consuming too much of our limited resources. Hopefully my next biannual SFW update will be that there isn't one! ;-) Time will tell...

As you may have seen, Web Stack 1.5 is out. Go ahead and give it a try!
One of the slightly confusing parts of the Web Stack distribution is that it varies by platform so there are several ways of "giving it a try". So it might be worth summarizing how and where to get it:
If you are on OpenSolaris 2009.06
Web Stack 1.5 is integrated into OpenSolaris 2009.06 out of the box. There is nothing to download. Simply install your favorite Web Stack components via the pkg(5) command. One shortcut is to install the 'amp' metapackage which will bring in a number of AMP-related Web Stack components (check the amp manifest to see precisely which ones it includes).
% pfexec pkg install amp
Note the 'amp' metapackage doesn't install all Web Stack components and you can just as well install only the ones you need, individually.
Yes, I realize OpenSolaris 2009.06 shipped last month! That means Web Stack 1.5 has been available in OpenSolaris for over a month now. So what is this week's announcement all about?
If you are on Solaris 10 or RedHat Linux
Well, unfortunately our shipping dates are a bit out of sync on different platforms (this is something I want to get aligned for the next time around) so what we're announcing this week is the availability of Web Stack 1.5 components on Solaris 10 and RedHat Linux.
There are two different packaging formats you may download for these platforms: native packages and update center images.
The native packages (svr4 for Solaris 10 and rpm for RedHat Linux) are what you'd expect, similar to the Web Stack 1.4 packages (and yes, you can upgrade your previous install if you wish).
The update center image is new in this release and it is quite interesting. Instead of downloading actual Web Stack components you only download an IPS user image which you may unzip anywhere you like, such as in your home directory. From within this user image you will then invoke the pkg(5) CLI to download and install those components you wish to use (there is also a GUI, updatetool, if you're into that).
Yes, this means you can install Web Stack components into any location you like while running as your regular nonprivileged (non-root) user. This is quite nice for experimenting and development work. Please refer to the README and documentation for details. Give it a try and let us know how you like it.
The other brand new cool thing in 1.5 is the Enterprise Manager GUI, which provides a really nice monitoring interface to component statistics.
Others from my team have written in more detail about various features so I won't repeat that here, just check these out:
- Brian has a release announcement.
- CVR also has a release announcement and some notes on the update center packaging.
- Sriram wrote about the release, how to install it and the Enterprise Manager.
- Irfan wrote about the Enterprise Manager and its navigation panel.
- Jeff wrote about Apache httpd updates in 1.5.
Finally, please note that while the full marketing name this quarter is Glassfish Web Stack, the Web Stack product is separate and completely unrelated to the Glassfish Application Server! I realize this has been the source of much confusion lately, particularly at OSCON last week.
Hopefully this helps clarify a bit how and where to obtain Web Stack 1.5! With that out of the way, now go give it a try!

As of today, the agenda shown on the above page is fairly preliminary and we'll be tailoring it depending on the schedule of the speakers as well as feedback we get in the next few days on topic interest (so feel free to let us know if there is anything in particular you want explored in depth - email@example.com).
It'll be informative and a good chance to meet several of the Web Stack component developers and maintainers, so I hope to see you all there!

Kind of a last minute announcement, but for those at the MySQL Conference today, CVR and myself will be hosting a Web Stack BoF tonight. We'll cover Web Stack in general but of course with an eye on MySQL on OpenSolaris in particular. We should have a few demos from Sriram and some slides, but mostly just open to any Web Stack discussion. Join us at 7:30pm!

A couple new opportunities to hear about Web Stack are coming up this month..
Next week (March 10th) as part of the 'Glassfish Boot Camp' here in Santa Clara we'll have a hands-on lab session on Web Stack. We'll do some quick demos and I expect there to be open time for questions, discussion and trying anything you might be curious about. Unfortunately (only if you are not signed up ;-) looks like the event is sold out by now.
The week after (March 18th) I'll be at CommunityOne East in New York City where we'll have a session titled 'OpenSolaris and the Web Stack: Apache, MySQL, PHP, NetBeans PHP IDE and Dtrace Integration'. I'll give a quick intro/background to Web Stack and then we'll have a number of demos. Check it out!

There are no enhancements to the packages this time other than the version so both are still rough (refer to my previous entries on each for their current state). These continue to be experimental components, so if you'd like to play with them please do and let firstname.lastname@example.org know how it works for you and any suggestions for improvement. If there is interest in these (or other) components, we can look into making the OpenSolaris integration stronger!

For us in Web Stack, the important part of this is that Sun is now selling support for the Web Stack components (and all other Glassfish portfolio components). So for those of you who've asked if or when can you get production support for Web Stack, now you can. Head over to http://www.sun.com/software/webstack/ and click on the "Contact Sales" link for more.
That's my ad for the week! Meanwhile, I'm pushing out some interesting updates to OpenSolaris Web Stack, I'll blog about those shortly....

With a mixture of sadness (because it hurts OpenSolaris adoption) and great amusement (because, really, how can they still be doing this!) it is now once again time for my biannual SFW build statistics update.
You may recall my original article on unconsolidating back in December 2007 where I pointed out all the problems with this peculiar practice and the inevitability of it collapsing under the weight of its own build time and size.
Later in June 2008 I posted an update on SFW build times. To summarize, at the time SFW was up to 205 packages and a build took about three and a half hours and 10GB of disk space. (Refer to the previous articles for more info on the simplifying assumptions behind the numbers.)
Fast forward to February 2009, where are we? I ran an SFW build overnight on the current bits (build 108 closed last night) and it took seven and a half hours and 12.3GB of disk space (on the same machine as I've run the previous two build tests).
A few observations...
- The build time has increased faster than the previous linear prediction. Using the current time/pkgs ratio, we'd be looking at 124 hours build time at 5000 packages (and 496 hours for 20,000 packages).
- The build disk size usage has increased slower than the previous linear prediction. Using current size/pkgs ratio, we'd be looking at 203GB to build 5000 packages (and 815GB to build 20,000 packages).
- The build is now up to a full working day. So any developer working on integrating (or fixing or updating) open source applications into OpenSolaris gets one shot per day of getting a clean nightly build (a requirement for integration).
Here is a graph of the data points so far. The dotted boxes at 5000 and 20000 packages show the range of predicted future build times.
And here is the data for the build size. While 12GB doesn't seem too bad given modern disk sizes, in practice it is also a big problem.
Web Stack engineering group we have several shared lab servers for doing development work and we are chronically running out of disk space (to the point that often builds fail due to lack of space, which isn't too amusing given the build took all day). With a handful of developers all of whom have a handful of workspaces (for different integration projects) going at the same time, 12GB at a time adds up surprisingly fast.
On the positive side, there has been some good news since my previous update. With the contrib repo up and running, there is an alternative to SFW (and of course, Web Stack project has its own Web Stack project repository but this is only for web tier components and not for general purpose components).
Sadly, this doesn't really help as much as it could because it is only being leveraged for packages which are considered unimportant and/or unsupported. So we continue to stuff most packages into SFW.
As before, it continues to be inevitable that SFW will collapse, it is only a matter of when it becomes so painful that it will no longer be possible to ignore the problem.
Any bets on the timeline?

I was reading through the comments and figured I'd throw in a few notes about what this code is and is not...
(I worked directly on the Web Server product for some years and while it is not my day job today, I'm still very closely affiliated with the group who works on the commercial version of this product inside Sun.)
- First, the released code is not a snapshot of the Netscape Enterprise Server from the 90's!
- What it is, is a snapshot of the very latest source code for JES Web Server 7.0 (with some non-core parts removed, such as the administration infrastructure - see full list of differences here.
- The commercial version of this product is actively maintained and sold by Sun (note it is free to download and use, however - so feel free to download both the source and the commercial binaries and try/compare both, if you wish).
- That said, the code is indeed a direct descendant of the Netscape Enterprise Server. The marketing name changes over the years have not marked rewrites of the core code, it's been the same code all along.
- While the revision history is not part of the open sourced snapshot (sorry), I can mention that in the internal repository of this code I see cvs comments dating back to 1995.
- With over ten years of development and bug fixing a lot has changed, naturally. On the other hand, if you were involved with the original product way back then, you'll definitely find some familiar bits and pieces here and there. As with any mature software product, there are always some parts which have not changed in ages.
- So, while not a mummified snapshot, the code is indeed interesting as a piece of Internet history. Furthermore, it is also interesting as a modern living product.
- Extreme scalability in multi-CPU (or multi-core) hardware is perhaps the most interesting angle from which to look at the code. (Funnily enough, with the rise of parallelism in modern hardware, maybe the code is becoming more interesting these days instead of less!)
- As to who or why be interested, that doesn't really have any one answer. If you find it interesting or useful for either reason (or some other of your own), enjoy! Being under BSD license, there are many ways to take advantage of it.

I'm happy to announce that our Web Server product (about which I've been writing here for a few years now) is now open sourced and available as part of the OpenSolaris Web Stack community!
Well, technically it is not exactly the Web Server product, since the open sourced code does not include some of the value-add components such as the administration framework. But it is the real deal, the massively scalable web server core which is used in the JES Web Server 7.0 product is now all open source!
This marks another milestone in the very long history of this web server. Back in the 90's this was the Netscape Enterprise Server, which later morphed into the iPlanet Web Server during the Sun|Netscape Alliance. After some years it was renamed the SunONE Web Server and most recently renamed again to the JES Web Server (Sun just like to keep you confused, thus the constant renaming of the product!)
The code is placed under BSD license, this should allow for good cross pollination with other web tier projects.
Source code is available via:
% hg clone ssh://email@example.com/hg/webstack/webserver
Build instructions are here: http://wikis.sun.com/display/wsFOSS/Build+Instructions
(The code itself is highly portable as you can see based on the supported platforms of the commercial product. Building on other platforms is a bit more involved due to dependencies so the build instructions only cover the more flexible platforms.)

I'm happy to announce Sun Web Stack 1.4 is now available for download!
Despite the confusing version number this is the first release of this new product. If you've been following my articles on OpenSolaris Web Stack then this product will seem quite familiar. In fact, Sun Web Stack 1.4 is a port of the primary OpenSolaris Web Stack components from 2008.11 to Solaris 10 (and RedHat Enterprise Linux).
So now you can take advantage of the work delivered by the Web Stack project on your existing Solaris 10 production systems and not only on OpenSolaris... Cool!
Speaking of cool, the strange version number (for a first release) is due to the fact that Sun Web Stack takes over where CoolStack left off. Since the final CoolStack release was 1.3, we decided to continue the version numbering as a nod to that continuity. Unlike CoolStack though, Sun Web Stack is a full-fledged Sun product, which means you'll have the option of purchasing support for it.
The packages are freely available of course. Here's some useful links:
I want to stress that Sun Web Stack is a port of the OpenSolaris Web Stack work. That means that future component upgrades and feature additions all go to OpenSolaris first and then will get promptly backported to Solaris 10 and RedHat under the Sun Web Stack banner. This also means that if you want to discuss future Web Stack directions, the best place is still firstname.lastname@example.org. The support forum I listed above is specifically for support questions related to using Sun Web Stack binaries on Solaris 10 or RedHat Linux. As the architect for both OpenSolaris Web Stack and Sun Web Stack, I'll continue covering both in this blog so stay tuned for more!
The initial design of this project started in September and it was mostly completed towards the end of last month. In conjunction with the OpenSolaris 2008.11 work, that made for very busy three months! So the timing of this release is perfect, just in time for the holiday break!
In short, if you've been following Web Stack work but are still on Solaris 10, go check out Sun Web Stack, give it a try and let us know what else you'd like to see included in the future.
Early in 2009 we will be planning on what to enhance and add to Web Stack for the next release of OpenSolaris (and thus, the next release of Sun Web Stack as well) so this is a good time to get your Web Stack wishes in!

As with all components in the Web Stack project repository, give them a try and if you find them useful (or if you don't find them useful for some reason!) let the project team know your thoughts at email@example.com. If you have any favorite web tier components or frameworks which you'd like to see available for OpenSolaris let us know that as well!
