--- Begin Message ---Package: libcompress-zlib-perl Version: 1.34-1 Severity: normal The manual page for Compress::Zlib is confusing when it comes to the section about compress() and uncompress(). It lists the $source argument, without explaining what it is supposed to represent. Is it a buffer or a file descriptor, for example? If it is a buffer, how is it different from the $buffer argument for memGzip() and memGunzip()? This quite is an example on what I am talking about: $dest = compress($source [, $level] ) ; Compresses $source. If successful it returns the compressed data. Otherwise it returns undef. The source buffer can either be a scalar or a scalar reference. I miss some more information about $source here. Can it be a filehandle? -- System Information: Debian Release: 3.1 Architecture: i386 (i686) Kernel: Linux 2.6.8-2-386 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Versions of packages libcompress-zlib-perl depends on: ii libc6 2.3.2.ds1-22 GNU C Library: Shared libraries an ii perl 5.8.4-8 Larry Wall's Practical Extraction ii perl-base [perlapi-5.8 5.8.4-8 The Pathologically Eclectic Rubbis ii zlib1g 1:1.2.2-4.sarge.1 compression library - runtime -- no debconf information

--- Begin Message ---Throughout the documentation, it is repeated in several places, just as you quote: The source buffer, $source, can either be a scalar or a scalar reference. In Perl, filehandles are not scalars :-) So, this works (scalar): perl -e 'use Compress::Zlib; open($in, "/etc/motd"); $data = join("", <$in>); print uncompress(compress($data, 9))' This also works (scalar reference): perl -e 'use Compress::Zlib; open($in, "/etc/motd"); $data = join("", <$in>); print uncompress(compress(\$data, 9))' This, of course, does not work (scalar reference reference) perl -e 'use Compress::Zlib; open($in, "/etc/motd"); $data = join("", <$in>); print uncompress(compress(\\$data, 9))' And no, this does not work (filehandle): perl -e 'use Compress::Zlib; open($in, "/etc/motd"); print uncompress(compress($in, 9))' So... The only thing that amazes me is that nobody touched this bug in three years and a half ;-) I'm closing it. -- Gunnar Wolf - [EMAIL PROTECTED] - (+52-55)5623-0154 / 1451-2244 PGP key 1024D/8BB527AF 2001-10-23 Fingerprint: 0C79 D2D1 2C4E 9CE4 5973 F800 D80E F35A 8BB5 27AF
