unzip extracts directories as symlinks

[Sean Hodges]

Binary package hint: unzip

Using "zip" to archive a set of directories, where one or more sub sirectories are symlinks, creates an archive that will not extract properly on another machine. Just to clarify this is WITHOUT using the -y switch (retain symlinks).

Unzip lists the directories and their contents correctly when using -l switch, however attempting to extract them gives a stream of errors:

checkdir error: EngineTest/materials exists but is not directory
                 unable to process EngineTest/materials/.svn/text-base/energy2_red.xml.svn-base.
checkdir error: EngineTest/materials exists but is not directory
                 unable to process EngineTest/materials/.svn/text-base/charon_flare3.xml.svn-base.
checkdir error: EngineTest/materials exists but is not directory
                 unable to process EngineTest/materials/.svn/text-base/charon_yellowclouds1.xml.svn-base.
.
.
...and finally...

finishing deferred symbolic links:
  EngineTest/textures -> /home/kazade/Desktop/mt-engine/build/codeblocks/textures
  EngineTest/maps -> /home/kazade/Desktop/mt-engine/build/codeblocks/maps
  EngineTest/materials -> /home/kazade/Desktop/mt-engine/build/codeblocks/materials

Sorry for the short bug report, I'll expand on it if anyone asks.

Is this symptom still reproducible in 8.10 RC or later?

I am having this same problem, it is driving me nuts. I can't unzip this .zip archive, so my whole workflow to a day is ground to a halt :(

I am trying to unzip http://wordpressthemesbase.com/download/762 using both file roller and the command line unzip.

In both instances, I get the exact same problem:

When trying to unzip some wordpress themes I had the same issue.
I've done some testing and found out why this happens. :)

If you do unzip -l on your zip file and the initial directory doesn't have a trailing slash, unzip will incorrectly create a file therefore blocking any attempts to write further files into that directory.

Examples:

1. This zip file causes errors on attempts to expand it.

unzip -l bluedark-10.zip

Archive: bluedark-10.zip
  Length Date Time Name
--------- ---------- ----- ----
        0 2010-01-21 07:06 bluedark-10 <------------ Notice there's no trailing slash for directory names
     1560 2009-11-09 17:35 bluedark-10/sidebar.php
     3375 2009-11-09 17:35 bluedark-10/header1.php
      222 2009-11-09 17:35 bluedark-10/links.php
     1942 2009-11-09 17:35 bluedark-10/single.php
        0 2009-11-09 17:35 bluedark-10/images <------------ Same here too !
     2820 2009-11-09 17:35 bluedark-10/images/panel.png
<snip>

2. This one works fine.

unzip -l themorningafter.zip

Archive: themorningafter.zip
  Length Date Time Name
--------- ---------- ----- ----
        0 2010-09-10 10:16 themorningafter/ <------------ This time, the trailing slash is present
     1124 2010-06-21 11:36 themorningafter/ie.css
     4457 2010-09-10 10:12 themorningafter/comments.php
     4656 2010-09-10 10:12 themorningafter/home.php
     3781 2010-09-10 10:12 themorningafter/archive.php
        0 2010-09-10 10:16 themorningafter/styles/ <------------ Here too.
        0 2010-09-10 10:16 themorningafter/styles/default/
       18 2010-06-21 11:36 themorningafter/styles/default.css
     4452 2010-09-10 10:12 themorningafter/header.php
        0 2010-09-10 10:16 themorningafter/functions/ <------------ Yada yada.
     1996 2010-06-21 11:36 themorningafter/functions/admin-theme-page.php
<snip>

Hope this helps someone.
I'll check with the upsteam developers, see if this issue is known about and post back more info.
