[Mingw-users] unzip : segmentation violation
for...@smartmobili.com
I am trying to install a web framework using the following script :
wget --no-check-certificate
https://raw.github.com/cappuccino/cappuccino/v0.9.5/bootstrap.sh
change line 139 :
tmp_zip="/tmp/cappuccino.zip" into
tmp_zip="./cappuccino.zip"
because it will be easier to debug
bash bootstrap.sh
Script tries to download a cappuccino.zip file and to unzip it but
unzip crashes with the following error :
error: zipfile probably corrupt (segmentation violation)
Error: problem running bootstrap.sh. Exiting.
once it failed I tried to run the command manually :
rm -Rf narwhal (clean our half unzipped folder)
unzip cappuccino-.zip -d ./narwhal/
Any idea ?

On the last version of msys/mingw on a Windows 7 64 bits it crashes.

The download probably did not fully complete. Can you open
cappuccino-.zip via the Windows File Explorer?

Actually it works when using windows file explorer or 7-zip.

It also works for me with unzip (and bsdtar, FWIW).
Perhaps your unzip is broken?

Don't think so because I also tried on another computer and I have
exactly the same error.
I am sure the zip is not corrupted because I tried on cygwin and it
works fine, I also
made a diff between the zip fecth with cygwin and the one with msys's
wget and they are the same.

Ah, symlinks! why didn't you show these message in the first place?

It sounds like your (Cygwin-compiled) unzip has some trouble with
symlinks in the archive. Which is mucho strange, because the archive
(at least the one I fetched with wget according to your instructions)
doesn't include symlinks at all. Specifically, the files you show
above are not symlinks, but rather ordinary files/directories. This
is part of a listing shown by MinGW-compiled bsdtar (which is quite
able to show symlinks in an archive, even if not to unpack them):
drwxrwxrwx 0 0 0 0 Nov 16 11:01 cappuccino-cappuccino-base-80ebdb7/tests/package/_files/test-sea/packages/

-rwxrwxrwx 0 0 0 9 Nov 16 11:01 cappuccino-cappuccino-base-80ebdb7/tests/package/_files/test-sea/packages/test-package-2/lib
May I suggest that you use MinGW-compiled tools (unzip, wget etc.) and
try again, starting with fetching the zip archive?

The issue is that at the time MSYS was developed Windows didn't
support symlinks and they just barely do now. Therefore, MSYS doesn't
support symlinks except to copy the files or directories that exist.
If the file or directory doesn't exist then you get an error because
there is nothing to copy.
The bsdtar that Eli has mentioned handles these symlink references so
that you don't crash and the whole archive minus the symlinks are
retrieved. If the file or directories exist bsdtar may later handle
the symlink references with the copy, I'm not sure what it does.
Chuck may know?
So to alleviate your issue:
mingw-get install bsdtar
<file name="/mingw/bin/unzip">
#! /bin/sh
/mingw/bin/bsdtar -xf "$1"
</file>

Yes it does.

The MinGW bsdtar handles the symlinks gracefully thanks to Chuck Wilson.

The OP is, you assumed that because the --version info contained the
word Cygwin he wasn't. I questioned that too at first until I looked
at the --version info in my own copy.

Can you show me how you see that, and what I missed? I see no
symlinks in the zip file, as I told.

I doubt that. I used bsdtar I compiled with MinGW myself from the
sources, and it only supports symlinks on Windows 7, while I'm on XP.
I definitely tested symlinks after building my bsdtar, and it
displayed error messages saying it is unable to create symlinks.

Well, there's no such word in mine:
