ClamAV broken version check

If you’ve just built and installed the new version 0.94 of ClamAV (because it reminded you that your current version was out of date), and you’re using the experimental features, it exposes a rather dumb bug that results in these messages in your freshclam log:

@4000000048be74fd0687f57c Software version from DNS: 0.94
@4000000048be74fd0688245c WARNING: Your ClamAV installation is OUTDATED!
@4000000048be74fd06883014 WARNING: Local version: 0.94-exp Recommended version: 0.94

Apparently ClamAV’s version comparison is not terribly clever, and the ‘new feature’ of marking experimental versions with ‘-exp’ has tripped it up. I’m sure there are multiple workarounds, but I changed this in shared/misc.c:

#ifdef CL_EXPERIMENTAL
/*#define EXP_VER “-exp”*/
#define EXP_VER
#else
#define EXP_VER
#endif

as the EXP_VER string is what gets appended to the version number (apparently only for display purposes, but it does the trick). I then rebuilt it and now my log says:

@4000000048be848926da098c Software version from DNS: 0.94

Yay – no error!

Safari 4 preview

I just grabbed the new update to the Safari 4 preview, and I have to say it’s very zippy indeed. I ran SunSpider benchmarks on it and FireFox 3.0.1 on my Mac Pro. Safari 4 is on average 75% faster, but has many results that are in the 200 – 500% range.

This is only measuring javascript performance of course, but that, plus whatever other changes are in S4, translates to incredible speed in daily use. I use the SafariStand extension to remember my open tabs, and I can reopen about 40 tabs in 8 windows in about 3 seconds, including all their content! FF 3 was a huge improvement over 2, but Safari 4 is a different league. This is only a preview, so it will probably get faster still by release.

The integration of the JS debugger is very elegant (Drosera has been rolled in), but I’m still looking forward to the appearance of FireBug for Safari, which someone is doing as a Google SoC project (S4 adds some FireBug hooks too).

All the new CSS funkiness from recent webkit nightlies is there too, and I suspect many an iPhone and widget developer is drooling over them…
