Description: ------------ Long file names does not unpack correctly when the prefix field in the TAR header is set. This is because Archive_Tar ignore that field. Test script: --------------- This is a sample tar that has some long image file names that incorrectly get extracted to root rather than into their target directory: https://github.com/melt/melt/tarball/1.0 Here is the patch I used which fixed the problem: @@ -1314,8 +1314,10 @@ $v_data = unpack("a100filename/a8mode/a8uid/a8gid/a12size/a12mtime/" ."a8checksum/a1typeflag/a100link/a6magic/a2version/" - ."a32uname/a32gname/a8devmajor/a8devminor", + ."a32uname/a32gname/a8devmajor/a8devminor/a131prefix", $v_binary_data); + if (strlen($v_data["prefix"]) > 0) + $v_data["filename"] = "$v_data[prefix]/$v_data[filename]"; // ----- Extract the checksum $v_header['checksum'] = OctDec(trim($v_data['checksum']));

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
