[ANN] Apache Commons Compress 1.15 Released
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
The Apache Commons Team is pleased to announce the release of Apache
Commons Compress 1.15.
The Apache Commons Compress Library defines an API for working with
compression and archive formats. These include: bzip2, gzip, pack200,
lzma, xz, Snappy, traditional Unix Compress, DEFLATE, LZ4, Brotli and
ar, cpio, jar, tar, zip, dump, 7z, arj.
Compress 1.15 contains big fixes and small improvements for the tar and
zip formats. In addition the jar's manifest file now contains an
Automatic-Module-Name entry that ensures the name will be
org.apache.commons.compress when the jar is used as an automatic module
in Java9.
TarArchiveOutputStream now ensures record size is 512 and block size is
a multiple of 512 as any other value would create invalid tar
archives. This may break compatibility for code that deliberately
wanted to create such files.
Source and binary distributions are available for download from the
Apache Commons download site:
http://commons.apache.org/proper/commons-compress/download_compress.cgi
When downloading, please verify signatures using the KEYS file available
at the above location when downloading the release.
Changes in this version include:
New features:
o Added magic MANIFEST entry Automatic-Module-Name so the module
name will be org.apache.commons.compress when the jar is used
as an automatic module in Java9.
Issue: COMPRESS-397.
o Added a new utility class FixedLengthBlockOutputStream that
can be used to ensure writing always happens in blocks of a
given size.
Issue: COMPRESS-405. Thanks to Simon Spero.
o It is now possible to specify/read custom PAX headers when
writing/reading tar archives.
Issue: COMPRESS-400. Thanks to Simon Spero.
Fixed Bugs:
o Make sure "version needed to extract" in local file header and
central directory of a ZIP archive agree with each other.
Also ensure the version is set to 2.0 if DEFLATE is used.
Issue: COMPRESS-394.
o Don't use a data descriptor in ZIP archives when copying a raw
entry that already knows its size and CRC information.
Issue: COMPRESS-395.
o Travis build redundantly repeats compilation and tests redundantly
GitHub Pull Request #43. Thanks to Simon Spero.
Issue: COMPRESS-413
o The MANIFEST of 1.14 lacks an OSGi Import-Package for XZ for
Java.
Issue: COMPRESS-396.
o BUILDING.md now passes the RAT check.
Issue: COMPRESS-406. Thanks to Simon Spero.
o Made sure ChecksumCalculatingInputStream receives valid
checksum and input stream instances via the constructor.
Issue: COMPRESS-412. Thanks to Michael Hausegger.
o TarArchiveOutputStream now verifies the block and record sizes
specified at construction time are compatible with the tar
specification. In particular 512 is the only record size
accepted and the block size must be a multiple of 512.
Issue: COMPRESS-407. Thanks to Simon Spero.
o Fixed class names of CpioArchiveEntry and
CpioArchiveInputStream in various Javadocs.
Issue: COMPRESS-415.
o The code of the extended timestamp zip extra field incorrectly
assumed the time was stored as unsigned 32-bit int and thus
created incorrect results for years after 2037.
Issue: COMPRESS-416. Thanks to Simon Spero.
o Removed ZipEncoding code that became obsolete when we started
to require Java 5 as baseline long ago.
Issue: COMPRESS-410. Thanks to Simon Spero.
o The tar package will no longer try to parse the major and
minor device numbers unless the entry represents a character
or block special file.
Issue: COMPRESS-417.
o When reading tar headers with name fields containing embedded
NULs, the name will now be terminated at the first NUL byte.
Issue: COMPRESS-421. Thanks to Roel Spilker.
o Simplified TarArchiveOutputStream by replacing the internal
buffering with new class FixedLengthBlockOutputStream.
Issue: COMPRESS-409.
