I honestly don't know all the pros and cons of zip vs tar.gz files.
Do you know when one would choose one over the other?
I'm no expert on this topic, but I think two of the relevant
differences
are:
- Zip has better tool support on Windows, while compressed tarballs
are
more common on UNIX/POSIX platforms. IMHO, we shouldn't care about
Windows in that regard, since while there may be something like
WinZip
on many (or even most) Windows machines, we can't rely on that, and
need something with a standardized command-line interface
anyway. OTOH, on GNU/Linux you can pretty much rely on tar and gzip
being present, and bzip2 is commonly installed as well (if not it's
just an "$PKG_MANAGER install" away :-).
1. On linux, there's no problem using either zip or tgz or whatever.
On windows, zip files are well supported (there is always the free
zip/unzip tools from info-zip.org that work on all platforms and is
well supported).
2. The different Unixes have incompatible "tar" utilities (there are
at least 3 flavors: gnu, bsd, and solaris, and I don't know what you'd
get under windows).
3. We can choose to interface directly with libzip to do whatever we
need to do. tgz files, being two-layer, are harder to process in
place.
I think we should go with zip files as I see no problem with it.
- The already mentioned random access issue. If we really need
that, it
would surely make the case for Zip.
It's good to have, even if we don't need it immediately.
