What kind of zip is used in 1.6?

[svasti]

Are there differnt types of zip files?
Usually in Win XP (sorry, not XH), I click on a zip file, which opens in a new window and i can move the files right away into a other normal folder, where they unpack automatically leaving the zip unchanged.
But this is not possible any more with the new kind of zip file of 1.6. Direct moving from the zip into another folder results in Windows complaining "can't find file xy".

Has anybody also this problem?

Well, there is no official standard for ZIP files (yet), and the de-facto standard from PKWARE offers lots of variations (e.g. uncompressed files in a ZIP archive). Cf. Wikipedia.

The "zipper" currently used for the CMSimple_XH distribution is Phing's ZipTask (I don't know which underlying library it is using -- one might have to look at the sources[1]).

But this is not possible any more with the new kind of zip file of 1.6. Direct moving from the zip into another folder results in Windows complaining "can't find file xy".

This works fine for me under Windows 7 and XP. However, looking in the ZIP with XP's built-in zipper shows an additional empty file for each folder! (Everything looks fine in 7zip, though.) After unzipping the complete archive everything is okay.

Do you have the same problems with the 1.6beta1 and 1.6rc1 ZIPs?

PS: JFTR: Phing's ZipTask is using PHP's ZipArchive class.

Is the build-in Window zipper that bad?

Yes, single files are ok, but folders don't work.

Used to have this on stone age Windows. Since Win XP came with an unzipper, I never missed it ... until now.

After unzipping the complete archive everything is okay.

Yes, but zips are more practical, as you cannot accidentally delete a file in it.

My simple solution is now:
Unzipping, renaming to CMSimple_XH_1-6 (XP cannot zip a folder with a dot in it!), rezipping it with Win XP.

The reason for using Phing's ZipTask is that it can be automated and is supposed to work on multiple platforms. The platform independency was the main reason for me to suggest to use Phing instead of make.

However, looking in the ZIP with XP's built-in zipper shows an additional empty file for each folder!

Well, what I meant is that for every folder in the archive, there is shown an empty file with the same name. That probably explains the error message "can't find file xy" when trying to extract a folder.

Anyway, I have rezipped the CMSimple_XH 1.6 distribution and uploaded it to SourceForge. Can you please confirm whether it's working now?

It works wonderful now.

Fine.

I guess we have to keep using another zipper for now, because PHP's implementation of ZipArchive seems to have a bug. (I'm very surprised that apparently this has not yet been detected.) I have filed a respective report.

After some more investigation I found that PHP will create conforming zip archives in 5.6.0 (maybe that will be backported). However, that won't solve the issues with Windows XP's built-in zipper which is not fully conforming to the specification. As XP will reach it's end-of-life in 3 months we should support it until then, and may switch to Phing's ZipTask afterwards. Can anybody check if the ZIP files work on Vista?

No problems for me with Vista .

Fine, thanks.
