Bug #78201 for Archive-Extract: Archive::Extract can't find unzip commund under FreeBSD

Subject:

Archive::Extract can't find unzip commund under FreeBSD

On FreeBSD there is /usr/bin/unzip command, installed as part of base system. But Archive::Extract ignores this command. Small test: #!/usr/bin/perl use 5.012; use warnings; use Archive::Extract; use IPC::Cmd qw[can_run]; my $ae = Archive::Extract->new( archive => 'ost.zip'); say '$ae->bin_unzip = '.$ae->bin_unzip; say 'IPC::Cmd::can_run = ' . can_run('unzip'); will output: Use of uninitialized value in concatenation (.) or string at ./ttt2.pl line 10. $ae->bin_unzip = IPC::Cmd::can_run = /usr/bin/unzip ---- I use Archive::Extract 0.58 but as I can see from source bug is still here. Why don't just use IPC::Cmd::can_run result in Archive::Extract?

This is very deliberate behaviour as the unzip command that has started shipping with FreeBSD (and NetBSD) in /usr/bin is unsuitable for the purposes of Archive::Extract. A::E relies on INFO-Zip unzip's -Z switch for getting a list of the files contained in the archive (unzip -Z -1 <archive>) The FreeBSD and NetBSD unzips do not provide this functionality. (You may though install archive/unzip from ports/pkgsrc which A::E will use). Cheers, -- Chris Williams aka BinGOs PGP ID 0x4658671F http://www.gumbynet.org.uk ==========================

unzip -Z -1 works under FreeBSD. x0083:~> uname -srp FreeBSD 8.3-STABLE-20120615 amd64 x0083:~> /usr/bin/unzip -Z -1 /usr/local/lib/python2.6/test/zipdir.zip a/ a/b/ a/b/c ---- Anyway /usr/bin/unzip is better than nothing. If boot /usr/local/bin/zip and /usr/bin/unzip than /usr/local/bin/zip can be preferred over /usr/bin.

For what it's worth, recent (i.e. supported: 7.x, 8.x, 9.x[0]) versions of FreeBSD ship with a /usr/bin/tar linked to libarchive which is fully capable of reading, listing, and extracting zip archives. If you're not running an ancient version of FreeBSD, you can assume /usr/bin/tar (with tar-like options) can do what you need. [0] Maybe even 6.x but no guarantees there

If it supports -Z it is INFO-Zip's unzip and FreeBSD do not ship that as /usr/bin/unzip The one they do ship only appeared as /usr/bin/unzip with 9.0 (despite what 'man unzip' reports). $ which unzip /usr/bin/unzip $ unzip -Z -1 unzip: illegal option -- Z usage: unzip [-aCcfjLlnopqtuv] [-d dir] [-x pattern] zipfile $ /usr/local/bin/unzip -Z -1 ZipInfo 3.00 of 20 April 2009, by Greg Roelofs and the Info-ZIP group.

This issue was resolved with the 0.78 release. From the commit message: Add additional heuristics for unzip on FreeBSD FreeBSD started shipping an unzip with 9.0-RELEASE in /usr/bin That unzip didn't have -Z1 switch. FreeBSD added the -Z switch starting with 9.1-RELEASE, but it was also backported to 8.4-RELEASE. MidnightBSD also appear to have an unzip which supports -Z1 as well since 0.4 Many thanks.
