Just a note that Pukka 1.6.6 final is out! Grab it here. For more details on the changes involved, see the last post. This release should iron out any remaining crash problems that users have been seeing on Leopard.

I've been hard at work trying to tackle some lingering Leopard stability issues with Pukka and believe that I have a solution. I'm releasing this fix as a prerelease (i.e. not advertised in the auto-update mechanism and not posted to the download sites -- please do not post it for me!) since the problems don't affect everyone and I'd like to have some feedback from those who are affected before making this version live.

Cut to the chase: download the prerelease version 1.6.6-pre2 for Tiger or Leopard. If you have any questions or concerns with this build, please contact me here.

(You may note that I'm using the same link for both OS versions -- I'm just trying to get some rudimentary usage stats by separating out the download URLs ;-)

If you're interested in some more technical info, read on.

It seems that Leopard has some lingering crash issues when using NSURLConnection, particularly when behind a proxy and/or using HTTPS and/or using authentication. Of particular concern are the last two conditions, as all Pukka traffic through del.icio.us, Ma.gnolia, and most alternative sites is over HTTPS with authentication. I have rarely been able to reproduce these crashes myself (which is the main reason I did not catch them in prerelease versions of Leopard), but I have received crash logs from issues with severity ranging from occasional problems to repeated crashing, including crashing on launch. Needless to say, this has been very frustrating.

Any other Cocoa programmers who use NSURLConnection will note that it is pretty much the way to do asynchronous downloads to memory (i.e. not to a file as NSURLDownload does) while easily working with requirements such as the ability to cancel, authentication, transparent proxy support, and cache management. I've been in a bit of a bind for a workaround, but after some discussions with (extremely helpful!) fellow Mac developers such as Daniel Jalkut, Jon Wight, and Fraser Speirs, I've settled on the solution of using CURLHandle routines in a dynamically loaded bundle when on Leopard for the time being, linking them against a Leopard-targeted CURLHandle framework to bypass cross-development issues with the framework. This required a fair amount of re-architecting since CURLHandle is not intended to be a drop-in replacement for NSURLConnection (in fact, it's a subclass of the Tiger-deprecated NSURLHandle class). It's a stable and reliable fix for Leopard until this bug is resolved, if not super-ideal for me as a developer. But them's the breaks!

For the reference of the Cocoa developers reading this, you can check out some bookmarks I've gathered (and will continue to gather) about issues with NSURLConnection over the years here and I've reported the Apple Radar bug and it resolves to the original at rdar://problem/5575834.

Update: I just released 1.6.6-pre2 to fix an issue that a couple people have noticed with double encoding of text when posting. The links have been updated above.

I've just released Pukka 1.6.3, which fixes several issues on Tiger and Leopard, including a hang and a potential crash.

As usual, you can update right in Pukka itself by choosing Pukka -> Check For Updates... while the application is running, or you can download Pukka from its page.

Enjoy!

I've been alerted by a number of users that there seem to be some odd issues with Bonjour support in Pukka on Leopard, particularly a slow startup time and/or a delay after launch. I'm working on this issue, but in the meantime, you can work around these issues by disabling Bonjour in Pukka's preferences.

Thanks for your patience and stay tuned for an update!

I've just released Pukka 1.6.2, which provides full compatibility with Mac OS X 10.5 "Leopard", due out today at 6pm Eastern. I've also corrected a small bug with the File -> Close menu item so that it works as expected when the preferences or about windows are in front. As always, you can get Pukka on its product page.

On the topic of Leopard, as many developers ^{1, 2, 3, 4, 5} have noted, despite having prerelease versions of Leopard over the past year or so, we do not actually get the final version as it ships tonight until we either go out and buy it ourselves or wait for our developer copy (in a few weeks?) So, to the best of my knowledge, Pukka will work with the Leopard release, but in the event that something unforeseen crops up, I will rectify it this weekend.

Now go get Pukka!

I said in my last post that I was behind and it shows in the number of things that I have to talk about regarding Pukka!

First up, my patch to the open source Vienna newsreader has made it into the stable version, which you can read about here. This helps with getting highlighted text out of Vienna and easily into your Pukka post.

Next, Seth Dillingham has reported on this blog that he has exceeded his fundraising goal for the Pan-Mass Challenge. I was able to donate some copies of Pukka to his effort and I'm glad to see that he reached (and exceeded) his goal!

Third, a few notes about social bookmarking in general and del.icio.us in particular. I have been testing out the preview of the next version of del.icio.us and will be keeping up on any changes that come about as a result of that. I also noticed a great video, which then ended up on the del.icio.us blog, about how to explain social bookmarking to people who are unfamiliar with it -- so check it out if you just don't get why you'd use Pukka.

Next, thanks to a post by Workshop friend Red Sweater Software, I was alerted to an app that recently added integration with Pukka. As of version 1.2.1, EagleFiler can capture post information from Pukka for better archival if you so choose. Neat!

I've also been keeping tabs on Apple's Leopard OS and to my knowledge, Pukka is doing fine on the latest build -- but please report if you find differently! I'm very excited for the Big Cat to arrive and very much looking forward to using some of its features full time next month!

And lastly, on a general business note, I wanted to report that I've been investigating how to better make Code Sorcery Workshop more green and sustainable and a better environmental citizen. I ran across a post by friend-of-the-Workshop Daniel Morrison about his efforts. Like his business, I too have minimal office needs. I also am able to take advantage of working remotely as well as DC's excellent public transportation in order to round out nearly a year now of essentially no driving for work. However, I do fly to conferences (though not many!), so that can always be reduced. I was also happy to learn last month that my webhost of eight years, pair Networks, has gone carbon neutral and is making other efforts to remain sustainable. This is a good trend! You can read more about pair's efforts here.

Whew! I think that's all for now. As I said, vacation is over and I'm back to working hard after playing hard. On a personal note, if you'd like to check out pictures from my 3,500 mile trip across the American Southwest, you can find them here. Enjoy!
