Title:
Archive::Zip does not close temporary archive files
Status in libarchive-zip-perl package in Ubuntu:
Fix Released
Bug description:
Ubuntu 15.10 contains Archive::Zip v 1.49 that apparently has a bug
that creating/updating a zip archive file does not close it , and
creating many files generates "too many open files" error similar to
this -
IO error: Can't open <.......>: Too many open files at /usr/share/perl5/Archive/Zip/FileMember.pm line 40. Archive::Zip::FileMember::_openFile(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/FileMember.pm line 30 Archive::Zip::FileMember::fh(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/ZipFileMember.pm line 384 Archive::Zip::ZipFileMember::rewindData(Archive::Zip::ZipFileMember=HASH(0x23e62b0)) called at /usr/share/perl5/Archive/Zip/Member.pm line 1059 Archive::Zip::Member::_writeToFileHandle(Archive::Zip::ZipFileMember=HASH(0x23e62b0), IO::File=GLOB(0x24399d0), 1, 0) called at /usr/share/perl5/Archive/Zip/Archive.pm line 420 Archive::Zip::Archive::writeToFileHandle(Archive::Zip::Archive=HASH(0x242eda8), IO::File=GLOB(0x24399d0)) called at /usr/share/perl5/Archive/Zip/Archive.pm line 456 Archive::Zip::Archive::overwriteAs(Archive::Zip::Archive=HASH(0x242eda8), "<.......>") called at /usr/share/perl5/Archive/Zip/Archive.pm line 440

lsof -p <pid> shows all /tmp/*zip files deleted, but still open, up to max open files (1000 which is system default)
Increasing number of files in limits.conf makes the problem generate less frequently.
installing latest version 1.56 from cpan fixes the problem - Using
many zip files correctly closes them, does not generate errors, and
lsof -p <pid> shows only several files (less than 20)
