-----------------------------------------------------------------------------
Release 1.21
------------
Compress 1.21 is the first release to require Java 8 to build and run.
SevenZFileOptions has a new setting that needs to be enabled
explicitly if SevenZFile should try to recover broken archives - a
feature introduced with Commons Compress 1.19. This is a breaking
change if you relied on the recovery attempt. The change was made to
detect broken archives sooner, and to mitigate the OOM exploit.
Several formats now throw IOExceptions when reading broken archives or
streams that would have caused arbitrary RuntimeExceptions in earlier
versions of Compress.
New features
------------
* Add writePreamble to ZipArchiveInputStream. This method could
write raw data to zip archive before any entry was written to
the zip archive.
For most of the time, this is used to create self-extracting
zip.
Github Pull Request #127.
Issue: COMPRESS-550.
Thanks to Scott Frederick.
* Added support for random access to the TAR packages.
Github Pull Request #113.
Issue: COMPRESS-540.
Thanks to Robin Schimpf.
* Added support for BufferPool in ZstdCompressorInputStream.
Github Pull Request #165.
Issue: COMPRESS-565.
Thanks to Michael L Heuer.
* Commons Compress cannot be built with JDK14 due to Pack200 removal.
Add Pack200 implementation from Apache Harmony.
Issue: COMPRESS-507.
Thanks to Gary Gregory, Apache Harmony.
* Add a new AlwaysWithCompatibility in Zip64Mode, this is a
compromise for some libraries including 7z and Expand-Archive
Powershell utility(and likely Excel).
And we will encode both the LFH offset and Disk Number Start
in the ZIP64 Extended Information Extra Field - even if only
the disk number needs to be encoded.
Github Pull Request #169.
Issue: COMPRESS-565.
Thanks to Evgenii Bovykin.
* gzip deflate buffer size is now configurable.
Issue: COMPRESS-566.
Thanks to Brett Okken.
Fixed Bugs
----------
* Fix bugs in random access of 7z. Problems may happen
in a mixture use of random access and sequential access
of 7z.
Github Pull Request #95.
Issue: COMPRESS-505.
* Fix bugs in random access of 7z. Exceptions are thrown
when reading the first entry multiple times by random
access.
Issue: COMPRESS-510.
* Add '/' to directories with long name in tar. This is to
resolve the ambiguous behavior of the TarArchiveEntry.getName()
method between directory with short name and long name.
Issue: COMPRESS-509.
Thanks to Petr Vasak.
* Removed the PowerMock dependency.
Issue: COMPRESS-520.
Thanks to Robin Schimpf.
* Added improved checks to detect corrupted bzip2 streams and
throw the expected IOException rather than obscure
RuntimeExceptions.
See also COMPRESS-519.
Issue: COMPRESS-516.
* Improved parsing of X5455_ExtendedTimestamp ZIP extra field.
Issue: COMPRESS-517.
* ZipArchiveInputStream and ZipFile will now throw an
IOException rather than a RuntimeException if the zip64 extra
field of an entry could not be parsed.
Issue: COMPRESS-518.
* Improved detection of corrupt ZIP archives in ZipArchiveInputStream.
Issue: COMPRESS-523.
* Added improved checks to detect corrupted deflate64 streams and
throw the expected IOException rather than obscure
RuntimeExceptions.
Issues: COMPRESS-521, COMPRESS-522, COMPRESS-525, COMPRESS-526, and COMPRESS-527.
* Add the archive name in the exception in the constructor of
ZipFile to make it a more specific exception.
Github Pull Request #102.
Issue: COMPRESS-515.
Thanks to ian-lavallee.
* Throw IOException when it encounters a non-number while parsing pax
header.
Issue: COMPRESS-530.
* Throw IOException when a tar archive contains a PAX header
without any normal entry following it.
Issue: COMPRESS-531.
* Added improved checks to detect corrupted IMPLODED streams and
throw the expected IOException rather than obscure
RuntimeExceptions.
Issue: COMPRESS-532.
* Throw expected IOException instead of NumberFormatException if
it encounters non-numbers when parsing pax headers for tarball.
Throw IllegalArgumentException instead of RuntimeExceptions if
the file name is longer than 100 bytes with the longFileMode
of LONGFILE_ERROR, and address this in java docs.
Throw IllegalArgumentException instead of RuntimeExceptions if
the any of the numeric values of an entry exceeds the limits
of a traditional tar header while bigNumberMode is
BIGNUMBER_ERROR, and address this in java docs.
Issue: COMPRESS-529.
* Fix for test fails on Windows. The tests are failing because the
default charset is not UTF-8.
Issue: COMPRESS-543.
Thanks to wulf2333.
* TarArchiveInputStream can not detect a truncated tar in skip()
and skipRecordPadding().
Issue: COMPRESS-544.
Thanks to Aditya Prasad.
* Make the memory allocation in SevenZFile.readFilesInfo a lazy
allocation to avoid OOM when dealing some giant 7z archives.
Github Pull Request #120.
Also added sanity checks before even trying to parse an
archive and made SevenZFileOptions' maxMemorySizeInKb apply to
the stored metadata for an archive.
And further added an option that needs to be enabled in order
to make SevenZFile try to recover a broken archive. This is a
backwards incompatible change.
Issue: COMPRESS-542.
Thanks to theobisproject.
* ZipArchiveInputStream should throw an exception if a corrputed
zip64 extra field is met.
Issue: COMPRESS-546.
Thanks to Maksim Zuev.
* Add a new maven profile in pom.xml for JDK14+ to ignore the
failing tests about Pack200.
This has later been superseeded by adding the Apache Harmony
classes for Pack200 support.
* Throw an IOException when reading the zip extra field if the
length is too short.
Issue: COMPRESS-548.
Thanks to Maksim Zuev.
* Throw an declared IOException if a null entry is met when
reading a global pax header instead of a runtime NPE.
Issue: COMPRESS-554.
Thanks to Maksim Zuev.
* ZIP extraction could lead to ArrayIndexOutOfBoundsExceptions
rather than the expected IOException.
Issue: COMPRESS-545.
Thanks to Maksim Zuev.
* Add asserts for Arrays.copyOf in X0017_StrongEncryptionHeader.
Issue: COMPRESS-547.
Thanks to Maksim Zuev.
* Fix for the CFH signature detect in ZipArchiveInputStream.
The problem could be reproduced by a zip archive with Data
Descriptor and STORED, and without the Data Descriptor
signature.
* The length validation in TarArchiveInputStream.parsePaxHeaders
should also consider the headers with length smaller than 1
and ignore these headers.
Issue: COMPRESS-553.
Thanks to Maksim Zuev.
* Fix accidentally added '/' to file names.
This problem is caused by the incomplete fix of COMPRESS-509.
Github Pull Request #151.
Issue: COMPRESS-558.
Thanks to Robin Schimpf.
* As sparse entries can be successfully parsed now,
TarArchiveInputStream.canReadEntryData should return
true if the entry is a sparse entry.
Github Pull Request #153.
Issue: COMPRESS-560.
Thanks to Robin Schimpf.
* SparseFilesTest#testExtractPaxGNU should be skipped
if the version of GNU tar binary is 1.28.
Github Pull Request #152.
Issue: COMPRESS-559.
Thanks to Robin Schimpf.
* Removed an empty loop that was just warming the planet for
certain ZIP archives.
Github Pull Request #172.
Thanks to Fabian Meumertzheim.
* Made some of the stream classes used internally throw
IOExceptions on illegal arguments rather than
RuntimeExceptions to make it more likely that corrupt archives
cause expected checked exceptions rather than RuntimException
for various formats.
Fixes a specific case for ZIP but affects other formats as
well.
Issue: COMPRESS-567.
* Simplify Assertions #205.
Thanks to Arturo Bernal.
* Checked the sizes read for archive entries and reject archives
as broken with negative entry sizes.
Fixes an infinite loop in the new TarFile class but affects
several formats.
Issue: COMPRESS-569.
* OSGi detection was broken and so we always cached whether
XZ/brotli/zstd/LZMA have been available even in OSGi
environments.
Issue: COMPRESS-552.
* SevenZFile.getEntries now return a copy of entries.
Issue: COMPRESS-571.
* Handling of sparse tar entries has been hardened to ensure bad
inputs cause expected IOExceptions rather than RuntimeExceptions.
Issue: COMPRESS-575.
* The parser for GNU sparse tar headers could throw a
NullPointerExcpetion rather than an IOException if the archive
ended while more sparse headers were expected.
Changes
-------
* Made sure ZstdCompressorOutputStream no longer used
deprecated ZstOutputStream constructors.
Github Pull Request #94.
Thanks to Peter Alfred Lee.
* Make compression level of ParallelScatterZipCreator
configurable via a new constructor.
Issue: COMPRESS-504.
* Made an inner class static
Github Pull Request #107.
Issue: COMPRESS-536.
Thanks to Jin Xu.
* added an early exit to a loop in BZip2CompressorOutputStream
Github Pull Request #106.
Issue: COMPRESS-535.
Thanks to Jin Xu.
* Update the class of variable file in TarArchiveEntry from
java.io.File to java.nio.file.Path. Corresponding constructors
and methods are also modified/added.
NOTE: The userName, groupName, userID and groupID will also be
set if they are available. The userName and groupName was not
set previously, and the previous value of UserID:GroupID was
0:0 by default.
Please note this may cause a reproducibility problem.

-----------------------------------------------------------------------------
Release 1.20
------------
Commons Compress 1.20 like any version of Commons Compress since 1.3
can not be built from sources using Java 14 as Java 14 removes
support for the Pack200 format. We will address this issue with the
next release.
Fixed Bugs
----------
* SevenZFile could throw NullPointerException rather than
IOException for certain archives. In addition it now handles
certain empty archives more gracefully.
Issue: COMPRESS-492.
* Deflate64CompressorInputStream.read would return 0 for some
inputs in violation of the InputStream.read contract.
Issue: COMPRESS-491.
* SeekableInMemoryByteChannel's truncate didn't set position
according to the spec in an edge case.
Issue: COMPRESS-499.
* BZip2CompressorInputStream now incorporates a similar patch as
the one that fixed CVE-2019-12900 in libbzip2.
Commons Compress has not been vulnerable to this CVE as it
would have rejected a file with too many selectors. With this
patch Commons Compress will be able to read certain archives
that would have caused errors in Compress 1.19. Thanks to Joseph Allemandou.
Changes
-------
* Update optional library com.github.luben:zstd-jni from
1.4.0-1 to 1.4.4-7.
Issue: COMPRESS-493.
* Update tests from org.apache.felix:org.apache.felix.framework
6.0.2 to 6.0.3.
* SevenZFile can now recover from a certain corruption that
seems to happen occasionally when split archives are created.
Issue: COMPRESS-497.
Thanks to Stefan Schlott.
* Added random access support to SevenZFile.
Issue: COMPRESS-342.
Thanks to Peter Alfred Lee.
* Added support for split ZIP archives.
Issue: COMPRESS-477.
Thanks to Peter Alfred Lee.
* Added support for reading sparse entries to the TAR package.
Issue: COMPRESS-124.
Thanks to Peter Alfred Lee.
* Update JUnit from 4.12 to 4.13.
Removed
-------
* Removed the extraction code from the example CLI class inside
of the SevenZ package. Not only is it superseeded by the
examples package, its implementation was vulnerable to the
ZipSlip attack.
Issue: COMPRESS-495.
-----------------------------------------------------------------------------
Release 1.19
------------
ZipArchiveInputStream and ZipFile will no longer throw an exception if
an extra field generally understood by Commons Compress is malformed
but rather turn them into UnrecognizedExtraField instances. You can
influence the way extra fields are parsed in more detail by using the
new getExtraFields(ExtraFieldParsingBehavior) method of
ZipArchiveEntry now.
Some of the ZIP extra fields related to strong encryption will now
throw ZipExceptions rather than ArrayIndexOutOfBoundsExceptions in
certain cases when used directly. There is no practical difference
when they are read via ZipArchiveInputStream or ZipFile.
New features
------------
* It is now possible to skip parsing of local file headers when
using ZipFile which may speed up reading the archive at the
cost of potentially missing important information. See the
javadocs of the ZipFile class for details.
Issue: COMPRESS-466.
* TarArchiveInputStream has a new constructor-arg lenient that
can be used to accept certain broken archives.
Issue: COMPRESS-469.
* ArjArchiveEntry and SevenZArchiveEntry now implement hashCode
and equals.
Issue: COMPRESS-475.
* Added a MultiReadOnlySeekableByteChannel class
that can be used to concatenate the parts of a multi volume 7z
archive so that SevenZFile can read them.
Issue: COMPRESS-231.
Thanks to Tim Underwood.
Fixed Bugs
----------
* ZipArchiveInputStream could forget the compression level has
changed under certain circumstances.
* Fixed another potential resource leak in
ParallelScatterZipCreator#writeTo.
Issue: COMPRESS-470.
* ArArchiveInputStream could think it had hit EOF prematurely.
Github Pull Request #74.
Thanks to Alex Bertram.
* Throw IOException rather than RuntimeExceptions for certain
malformed LZ4 or Snappy inputs.
Issue: COMPRESS-490.
* ZipArchiveInputStream failed to read stored entries with a
data descriptor if the data descriptor didn't use the
signature invented by InfoZIP.
Issue: COMPRESS-482.
Changes
-------
* SevenZFile now provides a way to cap memory consumption for
LZMA(2) compressed content.
Github Pull Request #76.
Issue: COMPRESS-481.
Thanks to Robin Schimpf.
* The ARJ package has been updated to contain constants for more
recent specifications.
Issue: COMPRESS-464.
Thanks to Rostislav Krasny.
* Update optional library zstd-jni from 1.3.3-3 to 1.4.0-1.
Issue: COMPRESS-484.
* ParallelScatterZipCreator now writes the entries to the
gathered output in the same order they have been added.
Github Pull Requests #78 and #79.
Issue: COMPRESS-485.
Thanks to Hervé Boutemy, Tibor Digana.
* The Expander and Archive example classes can leak resources
they have wrapped around passed in streams or channels. The
methods consuming streams and channels have been adapted to
give the calling code a chance to deal with those wrapper
resources.
Issue: COMPRESS-486.
* ZipArchiveInputStream and ZipFile no longer assume Commons
Compress would understand extra fields better than the writer
of the archive and silently turn extra fields that Commons
Compress should understand into UnrecognizedExtraFields if
parsing said fields fails.
It is now possible to take more control over the extra field
parsing process with a new overload of
ZipArchiveEntry#getExtraFields.
Issue: COMPRESS-479.
* ZipArchiveInputStream will now throw an exception if reading a
stored entry with a data descriptor and the data descriptor
doesn't match what it has actually read.
The most common case for a situation like this is a stored ZIP
archive inside of the archive ZipArchiveInputStream currently
reads. In such a case ZipArchiveInputStream would happily
extract the contained archive and stop once the central
directory of the inner archive has been hit. This is a case
where ZipArchiveInputStream simply can not be used and only
ZipFile is able to read the archive.
The only other explanation is a broken archive. So the
exception prevents users from thinking they had successfully
read the contents of the archive.
Issue: COMPRESS-483.
* The 7zip tools provide a default name for archive entries
without name; SevenZFile returns a null name for such
entries. A new method getDefaultName has been added to derive
the same name the 7zip tools would use and an option has been
added that sets SevenZArchiveEntry's name to the default name
if it is not contained inside the archive.
Issue: COMPRESS-478.
-----------------------------------------------------------------------------
Release 1.18
------------
This release changes the OSGi Manifest entry Bundle-SymbolicName from
org.apache.commons.compress to org.apache.commons.commons-compress.
New features
------------
* It is now possible to specify the arguments of zstd-jni's
ZstdOutputStream constructors via Commons Compress as well.
Issue: COMPRESS-460.
Thanks to Carmi Grushko.
Fixed Bugs
----------
* The example Expander class has been vulnerable to a path
traversal in the edge case that happens when the target
directory has a sibling directory and the name of the target
directory is a prefix of the sibling directory's name.
Thanks to Didier Loiseau.
* Changed the OSGi Import-Package to also optionally import
javax.crypto so encrypted archives can be read.
Issue: COMPRESS-456.
* Changed various implementations of the close method to better
ensure all held resources get closed even if exceptions are
thrown during the closing the stream.
Issue: COMPRESS-457.
* ZipArchiveInputStream can now detect the APK Signing Block
used in signed Android APK files and treats it as an "end of
archive" marker.
Issue: COMPRESS-455.
* The cpio streams didn't handle archives using a multi-byte
encoding properly.
Issue: COMPRESS-459.
Thanks to Jens Reimann.
* ZipArchiveInputStream#read would silently return -1 on a
corrupted stored entry and even return > 0 after hitting the
end of the archive.
Issue: COMPRESS-463.
* ArArchiveInputStream#read would allow to read from the stream
without opening an entry at all.
Issue: COMPRESS-462.
-----------------------------------------------------------------------------
Release 1.17
------------
New features
------------
* Added a unit test that is supposed to fail if we break the
OSGi manifest entries again.
Issue: COMPRESS-443.
* Add a new SkipShieldingInputStream class that can be used with
streams that throw an IOException when skip is invoked.
Issue: COMPRESS-449.
* New constructors have been added to SevenZFile that accept
char[]s rather than byte[]s in order to avoid a common error
of using the wrong encoding when creating the byte[]. This
change may break source compatibility for client code that
uses one of the constructors expecting a password and passes
in null as password. We recommend to change the code to use a
constructor without password argument.
Issue: COMPRESS-452.
Fixed Bugs
----------
* Removed the objenesis dependency from the pom as it is not
needed at all.
* Fixed resource leak in ParallelScatterZipCreator#writeTo.
Issue: COMPRESS-446.
* Certain errors when parsing ZIP extra fields in corrupt
archives are now turned into ZipException, they used to
manifest as ArrayIndexOutOfBoundsException before.
Issue: COMPRESS-447.
* IOUtils.copy now verifies the buffer size is bigger than 0.
Issue: COMPRESS-451.
* ZipArchiveInputStream failed to read some files with stored
entries using a data descriptor.
Issue: COMPRESS-454.
Changes
-------
* Fixed some code examples.
Github Pull Request #63.
Thanks to Marchenko Sergey.
* The streams returned by ZipFile and most other decompressing
streams now provide information about the number of compressed
and uncompressed bytes read so far. This may be used to detect
a ZipBomb if the compression ratio exceeds a certain
threshold, for example.
For SevenZFile a new method returns the statistics for the
current entry.
Issue: COMPRESS-445.
Thanks to Andreas Beeker.
* Added a workaround for a bug in AdoptOpenJDK for S/390 to
BZip2CompressorInputStream.
Issue: COMPRESS-453.

* Added a few extra sanity checks for the rarer compression
methods used in ZIP archives.
Issue: COMPRESS-436.
* Simplified the special handling for the dummy byte required by
zlib when using java.util.zip.Inflater.
Issue: COMPRESS-441.
* Various code cleanups.
Github Pull Request #61. Thanks to Shahab Kondri.

has been renamed and can now also be used to preserve the
drive letter on Windows.
-----------------------------------------------------------------------------
Release 1.15
------------
New features
------------
* 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.
* 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.
* It is now possible to specify/read custom PAX headers when
writing/reading tar archives.
Issue: COMPRESS-400. Thanks to Simon Spero.
Fixed Bugs
----------
* 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.
* 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.
* Travis build redundantly repeats compilation and tests redundantly
GitHub Pull Request #43. Thanks to Simon Spero.
Issue: COMPRESS-413
* The MANIFEST of 1.14 lacks an OSGi Import-Package for XZ for
Java.
Issue: COMPRESS-396.
* BUILDING.md now passes the RAT check.
Issue: COMPRESS-406. Thanks to Simon Spero.
* Made sure ChecksumCalculatingInputStream receives valid
checksum and input stream instances via the constructor.
Issue: COMPRESS-412. Thanks to Michael Hausegger.
* 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.
* Fixed class names of CpioArchiveEntry and
CpioArchiveInputStream in various Javadocs.
Issue: COMPRESS-415.
* 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.
* Removed ZipEncoding code that became obsolete when we started
to require Java 5 as baseline long ago.
Issue: COMPRESS-410. Thanks to Simon Spero.
* 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.
* 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.
* Simplified TarArchiveOutputStream by replacing the internal
buffering with new class FixedLengthBlockOutputStream.

-----------------------------------------------------------------------------
Release 1.14
------------
New features
------------

XZCompressorInputStream may use.
Issue: COMPRESS-382. Thanks to Tim Allison.
* Add Brotli decoder based on the Google Brotli library.
Issue: COMPRESS-392. Thanks to Philippe Mouawad.
* ZipEntry now exposes its data offset.
Issue: COMPRESS-390. Thanks to Zbynek Vyskovsky.
* Using ZipArchiveEntry's setAlignment it is now possible to
ensure the data offset of an entry starts at a file position
that at word or page boundaries.
A new extra field has been added for this purpose.
Issue: COMPRESS-391. Thanks to Zbynek Vyskovsky.
Fixed Bugs
----------
* SnappyCompressorInputStream slides the window too early
leading to ArrayIndexOutOfBoundsExceptions for some streams.
Issue: COMPRESS-378.
* ZipArchiveEntry#isUnixSymlink now only returns true if the
corresponding link flag is the only file-type flag set.
Issue: COMPRESS-379. Thanks to Guillaume Boué.
* Fixed an integer overflow in CPIO's CRC calculation.
Pull Request #17. Thanks to Daniel Collin.
* Make unit tests work on Windows paths with spaces in their names.
Issue: COMPRESS-387.

* LZMACompressorOutputStream#flush would throw an exception
rather than be the NOP it promised to be.
Issue: COMPRESS-393.
Changes
-------
* The blocksize for FramedSnappyCompressorInputStream can now be
configured as some IWA files seem to be using blocks larger
than the default 32k.
Issue: COMPRESS-358.
* BZip2CompressorInputstream now uses BitInputStream internally.
Pull Request #13. Thanks to Thomas Meyer.
* Improved performance for concurrent reads from ZipFile when

Issue: COMPRESS-388. Thanks to Zbynek Vyskovsky.
-----------------------------------------------------------------------------
Release 1.13
------------
Commons Compress 1.13 is the first version to require Java 7 at
runtime.
Changes in this version include:
New features
------------
* SevenZFile, SevenZOutputFile, ZipFile and
ZipArchiveOutputStream can now work on non-file resources if
they can be accessed via SeekableByteChannel.
Issue: COMPRESS-327.
* Allow compressor extensions through a standard JRE ServiceLoader.
Issue: COMPRESS-368.
* Allow archive extensions through a standard JRE ServiceLoader.
Issue: COMPRESS-369.
* Add write support for the legacy LZMA format, this requires XZ
for Java 1.6.
Issue: COMPRESS-373.
* Add write support for the legacy LZMA stream to 7z, this
requires XZ for Java 1.6.
Issue: COMPRESS-374.
* Allow the clients of ParallelScatterZipCreator to provide
ZipArchiveEntryRequestSupplier.
Issue: COMPRESS-375. Thanks to Plamen Totev.
* Add a version-independent link to the API docs of the latest
release.
Issue: COMPRESS-372.
Fixed Bugs
----------
* BitInputStream could return bad results when overflowing
internally - if two consecutive reads tried to read more than
64 bits.
Issue: COMPRESS-363.
* ZipArchiveInputStream.closeEntry does not properly advance to
next entry if there are junk bytes at end of data section.
Issue: COMPRESS-364. Thanks to Mike Mole.
* ZipArchiveInputStream now throws an Exception if it encounters
a broken ZIP archive rather than signaling end-of-archive.
Issue: COMPRESS-367. Thanks to Mike Mole.
* ScatterZipOutputStream didn't close the StreamCompressor
causing a potential resource leak.
Issue: COMPRESS-377.
Changes
-------
* Update Java requirement from 6 to 7.
Issue: COMPRESS-360.
* Clarified which TarArchiveEntry methods are useless for
entries read from an archive.
Issue: COMPRESS-366.
-----------------------------------------------------------------------------
Release 1.12
------------
Commons Compress 1.12 is the first version to require Java 6 at
runtime.
Release 1.12 changes the behavior of BZip2CompressorOutputStream's
finalize method so that it no longer invokes finish. This is going to
break code that relied on the finalizer to clean up an unfinished
stream. The code will need to be changed to call finish or close
itself. Note that a finalizer is not guaranteed to run, so the feature
was not 100% effective in any case.
New features
------------
* FramedSnappyCompressorInputStream now supports the dialect of
Snappy used by the IWA files contained within the zip archives
used in Apple's iWork 13 files.
Issue: COMPRESS-352.
Fixed Bugs
----------
* SevenZFile.read() throws an IllegalStateException for empty entries.
Issue: COMPRESS-348.
* TarArchiveInputStream failed to parse PAX headers that included
blank lines.
Issue: COMPRESS-355. Thanks to Jeremy Gustie.
* TarArchiveInputStream failed to parse PAX headers whose tar entry
name ended with a slash.
Issue: COMPRESS-356. Thanks to Jeremy Gustie.
Changes
-------
* Update requirement from Java 5 to 6.
Issue: COMPRESS-349.
* TarArchiveEntry wastefully allocates empty arrays.
Issue: COMPRESS-350.
* Javadoc for BZip2CompressorInputStream(InputStream, boolean) should
refer to IOEx, not NPE.
Issue: COMPRESS-353.
* PureJavaCrc32C in the snappy package is now final so it is now safe
to call a virtual method inside the constructor.
Issue: COMPRESS-354.
* ZipArchiveInputStream and CpioArchiveInputStream could throw
exceptions who's messages contained potentially corrupt entry names
read from a broken archive. They will now sanitize the names by
replacing unprintable characters and restricting the length to 255
characters.
Issue: COMPRESS-351.
* BZip2CompressorOutputStream no longer tries to finish the output
stream in finalize. This is a breaking change for code that relied
on the finalizer.
Issue: COMPRESS-357.
-----------------------------------------------------------------------------
Release 1.11
------------
New features
------------
* TarArchiveInputStream now supports reading global PAX headers.
Issue: COMPRESS-347.
* The PAX headers for sparse entries written by star are now
applied.
Issue: COMPRESS-346.
* GNU sparse files using one of the PAX formats are now
detected, but cannot be extracted.
Issue: COMPRESS-345.
* New method SevenZFile.getEntries can be used to list the
contents of a 7z archive.
Issue: COMPRESS-341.
* When using Zip64Mode.Always also use ZIP64 extensions inside
the central directory.
GitHub Pull Request #10 Thanks to Matt Hovey.
* ZipFile.getRawInputStream() is now part of the public API
Issue: COMPRESS-323.
* Allow byte-for-byte replication of Zip entries.
GitHub Pull Request #6. Thanks to Jason van Zyl.
* TarArchiveEntry's preserveLeadingSlashes is now a property and used
on later calls to setName, too.
This behavior is a breaking change.
Issue: COMPRESS-328.
* Added read-only support for bzip2 compression used inside of
ZIP archives.
GitHub Pull Request #4. Thanks to Sören Glimm.
Fixed Bugs
----------
* ArArchiveInputStream can now read GNU extended names that are
terminated with a NUL byte rather than a linefeed.
Issue: COMPRESS-344.
* Native Memory Leak in Sevenz-DeflateDecoder.
Issue: COMPRESS-343. Thanks to Rene Preissel.
* SevenZFile will now only try to drain an entry's content when
moving on to the next entry if data is read from the next
entry. This should improve performance for applications that
try to skip over entries.
Issue: COMPRESS-340. Thanks to Dawid Weiss.
* file names of tar archives using the xstar format are now
parsed properly.
Issue: COMPRESS-336.
* checksums of tars that pad the checksum field to the left are
now calculated properly.
Issue: COMPRESS-335.
* ArArchiveInputStream failed to read past the first entry when
BSD long names have been used.
Issue: COMPRESS-334. Thanks to Jeremy Gustie.
* Added buffering for random access which speeds up 7Z support.
Issue: COMPRESS-333. Thanks to Dawid Weiss.
* The checksum validation of TararchiveEntry is now as strict as
the validation of GNU tar, which eliminates a few cases of
false positives of ArchiveStreamFactory.
This behavior is a breaking change since the check has become
more strict but any archive that fails the checksum test now
would also fail it when extracted with other tools and must be
considered an invalid archive.
Issue: COMPRESS-331.
* SnappyCompressorInputStream and
FramedSnappyCompressorInputStream returned 0 at the end of the
stream under certain circumstances.
Issue: COMPRESS-332.
* Adjusted unit test to updates in Java8 and later that change
the logic of ZipEntry#getTime.
Issue: COMPRESS-326.
* TarArchiveOutputStream will now recognize GNU long name and
link entries even if the special entry has a different name
than GNU tar uses itself. This seems to be the case for
archives created by star.
Issue: COMPRESS-324.
* ArrayIndexOutOfBoundsException when InfoZIP type 7875 extra
fields are read from the central directory.
Issue: COMPRESS-321.
-----------------------------------------------------------------------------
Release 1.10
------------
Release 1.10 moves the former
org.apache.commons.compress.compressors.z._internal_ package which
breaks backwards compatibility for code which used the old package.
This also changes the superclass of ZCompressorInputStream which makes
this class binary incompatible with the one of Compress 1.9. Code
that extends ZCompressorInputStream will need to be recompiled in
order to work with Compress 1.10.
New features
------------
* CompressorStreamFactory can now auto-detect DEFLATE streams
with ZLIB header.
Issue: COMPRESS-316. Thanks to Nick Burch.
* CompressorStreamFactory can now auto-detect LZMA streams.
Issue: COMPRESS-313.
* Added support for parallel compression. This low-level API allows
a client to build a zip/jar file by using the class
org.apache.commons.compress.archivers.zip.ParallelScatterZipCreator.
Zip documentation updated with further notes about parallel features.
Please note that some aspects of jar creation need to be
handled by client code and is not part of commons-compress for this
release.
Issue: COMPRESS-296. Thanks to Kristian Rosenvold.
* Cut overall object instantiation in half by changing file
header generation algorithm, for a 10-15 percent performance
improvement.
Also extracted two private methods createLocalFileHeader
and createCentralFileHeader in ZipArchiveOutputStream.
These may have some interesting additional usages in the
near future. Thanks to Kristian Rosenvold.
* New methods in ZipArchiveOutputStream and ZipFile allows
entries to be copied from one archive to another without
having to re-compress them.
Issue: COMPRESS-295. Thanks to Kristian Rosenvold.
Fixed Bugs
----------
* TarArchiveInputStream can now read entries with group or
user ids > 0x80000000.
Issue: COMPRESS-314.
* TarArchiveOutputStream can now write entries with group or
user ids > 0x80000000.
Issue: COMPRESS-315.
* TarArchiveEntry's constructor with a File and a String arg
didn't normalize the name.
Issue: COMPRESS-312.
* ZipEncodingHelper no longer reads system properties directly
to determine the default charset.
Issue: COMPRESS-308.
* BZip2CompressorInputStream#read would return -1 when asked to
read 0 bytes.
Issue: COMPRESS-309.
* ArchiveStreamFactory fails to pass on the encoding when creating
some streams.
* ArjArchiveInputStream
* CpioArchiveInputStream
* DumpArchiveInputStream
* JarArchiveInputStream
* TarArchiveInputStream
* JarArchiveOutputStream
Issue: COMPRESS-306.
* Restore immutability/thread-safety to ArchiveStreamFactory.
The class is now immutable provided that the method setEntryEncoding
is not used. The class is thread-safe.
Issue: COMPRESS-302.
* Restore immutability/thread-safety to CompressorStreamFactory.
The class is now immutable provided that the method
setDecompressConcatenated is not used. The class is thread-safe.
Issue: COMPRESS-303.
* ZipFile logs a warning in its finalizer when its constructor
has thrown an exception reading the file - for example if the
file doesn't exist.
Issue: COMPRESS-297.
* Improved error message when tar encounters a groupId that is
too big to write without using the STAR or POSIX format.
Issue: COMPRESS-290. Thanks to Kristian Rosenvold.
* SevenZFile now throws the specific PasswordRequiredException
when it encounters an encrypted stream but no password has
been specified.
Issue: COMPRESS-298.
Changes
-------
* Moved the package
org.apache.commons.compress.compressors.z._internal_ to
org.apache.commons.compress.compressors.lzw and made it part
of the API that is officially supported. This will break
existing code that uses the old package. Thanks to Damjan Jovanovic.

-----------------------------------------------------------------------------
Release 1.9
-----------
New features
------------
* Added support for DEFLATE streams without any gzip framing.
Issue: COMPRESS-263.
Thanks to Matthias Stevens.
Fixed Bugs
----------
* When reading 7z files unknown file properties and properties of type
kDummy are now ignored.
Issue: COMPRESS-287.
* Expanding 7z archives using LZMA compression could cause an
EOFException.
Issue: COMPRESS-286.
* Long-Name and -link or PAX-header entries in TAR archives always had
the current time as last modfication time, creating archives that
are different at the byte level each time an archive was built.
Issue: COMPRESS-289.
Thanks to Bob Robertson.
Changes
-------
* Checking for XZ for Java may be expensive. The result will now be
cached outside of an OSGi environment. You can use the new
XZUtils#setCacheXZAvailability to overrride this default behavior.
Issue: COMPRESS-285.
-----------------------------------------------------------------------------
Release 1.8.1
-------------
New features
------------
* COMPRESS-272: CompressorStreamFactory can now auto-detect Unix compress
(".Z") streams.
Fixed Bugs
----------
* COMPRESS-270: The snappy, ar and tar inputstreams might fail to read from a
non-buffered stream in certain cases.
* COMPRESS-277: IOUtils#skip might skip fewer bytes than requested even though
more could be read from the stream.
* COMPRESS-276: ArchiveStreams now validate there is a current entry before
reading or writing entry data.
* ArjArchiveInputStream#canReadEntryData tested the current
entry of the stream rather than its argument.
* COMPRESS-274: ChangeSet#delete and deleteDir now properly deal with unnamed
entries.
* COMPRESS-273: Added a few null checks to improve robustness.
* COMPRESS-278: TarArchiveInputStream failed to read archives with empty
gid/uid fields.
* COMPRESS-279: TarArchiveInputStream now again throws an exception when it
encounters a truncated archive while reading from the last
entry.
* COMPRESS-280: Adapted TarArchiveInputStream#skip to the modified
IOUtils#skip method. Thanks to BELUGA BEHR.
Changes
-------
* The dependency on org.tukaani:xz is now marked as optional.
-----------------------------------------------------------------------------
Release 1.8
-----------
New features
------------
* GzipCompressorInputStream now provides access to the same
metadata that can be provided via GzipParameters when writing
a gzip stream.
Issue: COMPRESS-260.
* SevenZOutputFile now supports chaining multiple
compression/encryption/filter methods and passing options to
the methods.
Issue: COMPRESS-266.
* The (compression) method(s) can now be specified per entry in
SevenZOutputFile.
Issue: COMPRESS-261.
* SevenZArchiveEntry "knows" which method(s) have been used to
write it to the archive.
Issue: COMPRESS-258.
* The 7z package now supports the delta filter as method.
* The 7z package now supports BCJ filters for several platforms.
You will need a version >= 1.5 of XZ for Java to read archives
using BCJ, though.
Issue: COMPRESS-257.
Fixed Bugs
----------
* BZip2CompressorInputStream read fewer bytes than possible from
a truncated stream.
Issue: COMPRESS-253.
* SevenZFile failed claiming the dictionary was too large when
archives used LZMA compression for headers and content and
certain non-default dictionary sizes.
Issue: COMPRESS-253.
* CompressorStreamFactory.createCompressorInputStream with
explicit compression did not honor decompressConcatenated
Issue: COMPRESS-259.
* TarArchiveInputStream will now read archives created by tar
implementations that encode big numbers by not adding a
trailing NUL.
Issue: COMPRESS-262.
* ZipArchiveInputStream would return NUL bytes for the first 512
bytes of a STORED entry if it was the very first entry of the
archive.
Issue: COMPRESS-264.
* When writing PAX/POSIX headers for TAR entries with
backslashes or certain non-ASCII characters in their name
TarArchiveOutputStream could fail.
Issue: COMPRESS-265.
* ArchiveStreamFactory now throws a StreamingNotSupported - a
new subclass of ArchiveException - if it is asked to read from
or write to a stream and Commons Compress doesn't support
streaming for the format. This currently only applies to the
7z format.
Issue: COMPRESS-267.
-----------------------------------------------------------------------------
Release 1.7
-----------
New features
------------
* Read-Only support for Snappy compression.
Issue: COMPRESS-147. Thanks to BELUGA BEHR.
* Read-Only support for .Z compressed files.
Issue: COMPRESS-243. Thanks to Damjan Jovanovic.
* ZipFile and ZipArchiveInputStream now support reading entries
compressed using the SHRINKING method. Thanks to Damjan Jovanovic.
* GzipCompressorOutputStream now supports setting the compression
level and the header metadata (filename, comment, modification time,
operating system and extra flags)
Issue: COMPRESS-250. Thanks to Emmanuel Bourg.
* ZipFile and ZipArchiveInputStream now support reading entries
compressed using the IMPLODE method.
Issue: COMPRESS-115. Thanks to Emmanuel Bourg.
* ZipFile and the 7z file classes now implement Closeable and can be
used in try-with-resources constructs.
Fixed Bugs
----------
* SevenZOutputFile#closeArchiveEntry throws an exception when using
LZMA2 compression on Java8. Issue: COMPRESS-241.
* 7z reading of big 64bit values could be wrong.
Issue: COMPRESS-244. Thanks to Nico Kruber.
* TarArchiveInputStream could fail to read an archive completely.
Issue: COMPRESS-245.
* The time-setters in X5455_ExtendedTimestamp now set the
corresponding flags explicitly - i.e. they set the bit if the valus
is not-null and reset it otherwise. This may cause
incompatibilities if you use setFlags to unset a bit and later set
the time to a non-null value - the flag will now be set.
Issue: COMPRESS-242.
* SevenZOutputFile would create invalid archives if more than six
empty files or directories were included. Issue: COMPRESS-252.
-----------------------------------------------------------------------------
Release 1.6
-----------
Version 1.6 introduces changes to the internal API of the tar package that
break backwards compatibility in the following rare cases. This version
removes the package private TarBuffer class along with the protected "buffer"
members in TarArchiveInputStream and TarArchiveOutputStream. This change will
only affect you if you have created a subclass of one of the stream classes
and accessed the buffer member or directly used the TarBuffer class.
Changes in this version include:
New features
------------
* Added support for 7z archives. Most compression algorithms
can be read and written, LZMA and encryption are only
supported when reading. Issue: COMPRESS-54. Thanks to Damjan Jovanovic.
* Added read-only support for ARJ archives that don't use
compression. Issue: COMPRESS-226. Thanks to Damjan Jovanovic.
* DumpArchiveInputStream now supports an encoding parameter that
can be used to specify the encoding of file names.
* The CPIO streams now support an encoding parameter that can be
used to specify the encoding of file names.
* Read-only support for LZMA standalone compression has been added.
Issue: COMPRESS-111.
Fixed Bugs
----------
* TarBuffer.tryToConsumeSecondEOFRecord could throw a
NullPointerException Issue: COMPRESS-223. Thanks to Jeremy Gustie.
* Parsing of zip64 extra fields has become more lenient in order
to be able to read archives created by DotNetZip and maybe
other archivers as well. Issue: COMPRESS-228.
* TAR will now properly read the names of symbolic links with
long names that use the GNU variant to specify the long file
name. Issue: COMPRESS-229. Thanks to Christoph Gysin.
* ZipFile#getInputStream could return null if the archive
contained duplicate entries.
The class now also provides two new methods to obtain all
entries of a given name rather than just the first one.
Issue: COMPRESS-227.
* CpioArchiveInputStream failed to read archives created by
Redline RPM. Issue: COMPRESS-236. Thanks to Andrew Duffy.
* TarArchiveOutputStream now properly handles link names that
are too long to fit into a traditional TAR header. Issue:
COMPRESS-237. Thanks to Emmanuel Bourg.
* The auto-detecting create*InputStream methods of Archive and
CompressorStreamFactory could fail to detect the format of
blocking input streams. Issue: COMPRESS-239.
Changes
-------
* Readabilty patch to TarArchiveInputStream. Issue:
COMPRESS-232. Thanks to BELUGA BEHR.
* Performance improvements to TarArchiveInputStream, in
particular to the skip method. Issue: COMPRESS-234. Thanks to
BELUGA BEHR.
-----------------------------------------------------------------------------
Release 1.5
-----------
New features
------------
* CompressorStreamFactory has an option to create decompressing
streams that decompress the full input for formats that support
multiple concatenated streams.
Issue: COMPRESS-220.
Fixed Bugs
----------
* Typo in CompressorStreamFactory Javadoc
Issue: COMPRESS-218.
Thanks to Gili.
* ArchiveStreamFactory's tar stream detection created false positives
for AIFF files.
Issue: COMPRESS-191.
Thanks to Jukka Zitting.
* XZ for Java didn't provide an OSGi bundle. Compress' dependency on
it has now been marked optional so Compress itself can still be used
in an OSGi context.
Issue: COMPRESS-199.
Thanks to Jukka Zitting.
* When specifying the encoding explicitly TarArchiveOutputStream would
write unreadable names in GNU mode or even cause errors in POSIX
mode for file names longer than 66 characters.
Issue: COMPRESS-200.
Thanks to Christian Schlichtherle.
* Writing TAR PAX headers failed if the generated entry name ended
with a "/".
Issue: COMPRESS-203.
* ZipArchiveInputStream sometimes failed to provide input to the
Inflater when it needed it, leading to reads returning 0.
Issue: COMPRESS-189.
Thanks to Daniel Lowe.
* TarArchiveInputStream ignored the encoding for GNU long name
entries.
Issue: COMPRESS-212.
* TarArchiveInputStream could leave the second EOF record inside the
stream it had just finished reading.
Issue: COMPRESS-206.
Thanks to Peter De Maeyer.
* DumpArchiveInputStream no longer implicitly closes the original
input stream when it reaches the end of the archive.
* ZipArchiveInputStream now consumes the remainder of the archive when
getNextZipEntry returns null.
* Unit tests could fail if the source tree was checked out to a
directory tree containign spaces.
Issue: COMPRESS-205.
Thanks to Daniel Lowe.
* Fixed a potential ArrayIndexOutOfBoundsException when reading STORED
entries from ZipArchiveInputStream.
Issue: COMPRESS-219.
* CompressorStreamFactory can now be used without XZ for Java being
available.
Issue: COMPRESS-221.
Changes
-------
* Improved exception message if a zip archive cannot be read because
of an unsupported compression method.
Issue: COMPRESS-188.
Thanks to Harald Kuhn.
* ArchiveStreamFactory has a setting for file name encoding that sets
up encoding for ZIP and TAR streams.
Issue: COMPRESS-192.
Thanks to Jukka Zitting.
* TarArchiveEntry now has a method to verify its checksum.
Issue: COMPRESS-191.
Thanks to Jukka Zitting.
* Split/spanned ZIP archives are now properly detected by
ArchiveStreamFactory but will cause an
UnsupportedZipFeatureException when read.
* ZipArchiveInputStream now reads archives that start with a "PK00"
signature. Archives with this signatures are created when the
archiver was willing to split the archive but in the end only needed
a single segment - so didn't split anything.
Issue: COMPRESS-208.
* TarArchiveEntry has a new constructor that allows setting linkFlag
and preserveLeadingSlashes at the same time.
Issue: COMPRESS-201.
* ChangeSetPerformer has a new perform overload that uses a ZipFile
instance as input.
Issue: COMPRESS-159.
* Garbage collection pressure has been reduced by reusing temporary
byte arrays in classes.
Issue: COMPRESS-172.
Thanks to Thomas Mair.
* Can now handle zip extra field 0x5455 - Extended Timestamp.
Issue: COMPRESS-210.
Thanks to Julius Davies.
* handle zip extra field 0x7875 - Info Zip New Unix Extra Field.
Issue: COMPRESS-211.
Thanks to Julius Davies.
* ZipShort, ZipLong, ZipEightByteInteger should implement Serializable
Issue: COMPRESS-213.
Thanks to Julius Davies.
* better support for Unix symlinks in ZipFile entries.
Issue: COMPRESS-214.
Thanks to Julius Davies.
* ZipFile's initialization has been improved for non-Zip64 archives.
Issue: COMPRESS-215.
Thanks to Robin Power.
* Updated XZ for Java dependency to 1.2 as this version provides
proper OSGi manifest attributes.
-----------------------------------------------------------------------------
Release 1.4.1
-------------
This is a security bugfix release, see
https://commons.apache.org/proper/commons-compress/security.html#Fixed_in_Apache_Commons_Compress_1.4.1
Fixed Bugs
----------
* Ported libbzip2's fallback sort algorithm to
BZip2CompressorOutputStream to speed up compression in certain
edge cases.
-----------------------------------------------------------------------------
Release 1.4
-----------
New features
------------
* COMPRESS-156: Support for the XZ format has been added.
Fixed Bugs
----------
* COMPRESS-183: The tar package now allows the encoding of file names to be
specified and can optionally use PAX extension headers to
write non-ASCII file names.
The stream classes now write (or expect to read) archives that
use the platform's native encoding for file names. Apache
Commons Compress 1.3 used to strip everything but the lower
eight bits of each character which effectively only worked for
ASCII and ISO-8859-1 file names.
This new default behavior is a breaking change.
* COMPRESS-184: TarArchiveInputStream failed to parse PAX headers that
contained non-ASCII characters.
* COMPRESS-178: TarArchiveInputStream throws IllegalArgumentException instead of IOException
* COMPRESS-179: TarUtils.formatLongOctalOrBinaryBytes() assumes the field will be 12 bytes long
* COMPRESS-175: GNU Tar sometimes uses binary encoding for UID and GID
* COMPRESS-171: ArchiveStreamFactory.createArchiveInputStream would claim
short text files were TAR archives.
* COMPRESS-164: ZipFile didn't work properly for archives using unicode extra
fields rather than UTF-8 filenames and the EFS-Flag.
* COMPRESS-169: For corrupt archives ZipFile would throw a RuntimeException in
some cases and an IOException in others. It will now
consistently throw an IOException.
Changes
-------
* COMPRESS-182: The tar package can now write archives that use star/GNU/BSD
extensions or use the POSIX/PAX variant to store numeric
values that don't fit into the traditional header fields.
* COMPRESS-181: Added a workaround for a Bug some tar implementations that add
a NUL byte as first byte in numeric header fields.
* COMPRESS-176: Added a workaround for a Bug in WinZIP which uses backslashes
as path separators in Unicode Extra Fields.
* COMPRESS-131: ArrayOutOfBounds while decompressing bz2. Added test case - code already seems to have been fixed.
* COMPRESS-146: BZip2CompressorInputStream now optionally supports reading of
concatenated .bz2 files.
* COMPRESS-154: GZipCompressorInputStream now optionally supports reading of
concatenated .gz files.
* COMPRESS-16: The tar package can now read archives that use star/GNU/BSD
extensions for files that are longer than 8 GByte as well as
archives that use the POSIX/PAX variant.
* COMPRESS-165: The tar package can now write archives that use star/GNU/BSD
extensions for files that are longer than 8 GByte as well as
archives that use the POSIX/PAX variant.
* COMPRESS-166: The tar package can now use the POSIX/PAX variant for writing
entries with names longer than 100 characters.
-----------------------------------------------------------------------------
Release 1.3
-----------
Commons Compress 1.3 is the first version to require Java5 at runtime.
Changes in this version include:
New features
------------
* Support for the Pack200 format has been added. Issue: COMPRESS-142.
* Read-only support for the format used by the Unix dump(8) tool
has been added. Issue: COMPRESS-132.
Fixed Bugs
----------
* BZip2CompressorInputStream's getBytesRead method always
returned 0.
* ZipArchiveInputStream and ZipArchiveOutputStream could leak
resources on some JDKs. Issue: COMPRESS-152.
* TarArchiveOutputStream's getBytesWritten method didn't count
correctly. Issue: COMPRESS-160.
Changes
-------
* The ZIP package now supports Zip64 extensions. Issue: COMPRESS-36.
* The AR package now supports the BSD dialect of storing file
names longer than 16 chars (both reading and writing).
Issue: COMPRESS-144.
-----------------------------------------------------------------------------
Release 1.2
-----------
New features
------------
* COMPRESS-123: ZipArchiveEntry has a new method getRawName that provides the
original bytes that made up the name. This may allow user
code to detect the encoding.
* COMPRESS-122: TarArchiveEntry provides access to the flags that determine
whether it is an archived symbolic link, pipe or other
"uncommon" file system object.
Fixed Bugs:
* COMPRESS-129: ZipArchiveInputStream could fail with a "Truncated ZIP" error
message for entries between 2 GByte and 4 GByte in size.
* COMPRESS-145: TarArchiveInputStream now detects sparse entries using the
oldgnu format and properly reports it cannot extract their
contents.
* COMPRESS-130: The Javadoc for ZipArchiveInputStream#skip now matches the
implementation, the code has been made more defensive.
* COMPRESS-140: ArArchiveInputStream fails if entries contain only blanks for
userId or groupId. Thanks to Trejkaz.
* COMPRESS-139: ZipFile may leak resources on some JDKs.
* COMPRESS-125: BZip2CompressorInputStream throws IOException if
underlying stream returns available() == 0.
Removed the check.
* COMPRESS-127: Calling close() on inputStream returned by
CompressorStreamFactory.createCompressorInputStream()
does not close the underlying input stream.
* COMPRESS-119: TarArchiveOutputStream#finish now writes all buffered
data to the stream
Changes
-------
* ZipFile now implements finalize which closes the underlying
file.
* COMPRESS-117: Certain tar files not recognised by
ArchiveStreamFactory.
-----------------------------------------------------------------------------
Release 1.1
-----------
New features
------------
* COMPRESS-108: Command-line interface to list archive contents.
Usage: java -jar commons-compress-n.m.jar archive-name [zip|tar|etc]
* COMPRESS-109: Tar implementation does not support Pax headers
Added support for reading pax headers.
Note: does not support global pax headers
* COMPRESS-103: ZipArchiveInputStream can optionally extract data that used
the STORED compression method and a data descriptor.
Doing so in a stream is not safe in general, so you have to
explicitly enable the feature. By default the stream will
throw an exception if it encounters such an entry.
* COMPRESS-98: The ZIP classes will throw specialized exceptions if any
attempt is made to read or write data that uses zip features
not supported (yet).
* COMPRESS-99: ZipFile#getEntries returns entries in a predictable order -
the order they appear inside the central directory.
A new method getEntriesInPhysicalOrder returns entries in
order of the entry data, i.e. the order ZipArchiveInputStream
would see.
* The Archive*Stream and ZipFile classes now have
can(Read|Write)EntryData methods that can be used to check
whether a given entry's data can be read/written.
The method currently returns false for ZIP archives if an
entry uses an unsupported compression method or encryption.
* COMPRESS-89: The ZIP classes now detect encrypted entries.
* COMPRESS-97: Added autodetection of compression format to
CompressorStreamFactory.
* COMPRESS-95: Improve ExceptionMessages in ArchiveStreamFactory Thanks to Joerg Bellmann.
* A new constructor of TarArchiveEntry can create entries with
names that start with slashes - the default is to strip
leading slashes in order to create relative path names.
* ArchiveEntry now has a getLastModifiedDate method.
* COMPRESS-78: Add a BZip2Utils class modelled after GZipUtils Thanks to Jukka Zitting.
Fixed Bugs
----------
* COMPRESS-72: Move acknowledgements from NOTICE to README
* COMPRESS-113: TarArchiveEntry.parseTarHeader() includes the trailing space/NUL when parsing the octal size
* COMPRESS-118: TarUtils.parseName does not properly handle characters outside the range 0-127
* COMPRESS-107: ArchiveStreamFactory does not recognise tar files created by Ant
* COMPRESS-110: Support "ustar" prefix field, which is used when file paths are longer
than 100 characters.
* COMPRESS-100: ZipArchiveInputStream will throw an exception if it detects an
entry that uses a data descriptor for a STORED entry since it
cannot reliably find the end of data for this "compression"
method.
* COMPRESS-101: ZipArchiveInputStream should now properly read archives that
use data descriptors but without the "unofficial" signature.
* COMPRESS-74: ZipArchiveInputStream failed to update the number of bytes
read properly.
* ArchiveInputStream has a new method getBytesRead that should
be preferred over getCount since the later may truncate the
number of bytes read for big archives.
* COMPRESS-85: The cpio archives created by CpioArchiveOutputStream couldn't
be read by many existing native implementations because the
archives contained multiple entries with the same inode/device
combinations and weren't padded to a blocksize of 512 bytes.
* COMPRESS-73: ZipArchiveEntry, ZipFile and ZipArchiveInputStream are now
more lenient when parsing extra fields.
* COMPRESS-82: cpio is terribly slow.
Documented that buffered streams are needed for performance
* Improved exception message if the extra field data in ZIP
archives cannot be parsed.
* COMPRESS-17: Tar format unspecified - current support documented.
* COMPRESS-94: ZipArchiveEntry's equals method was broken for entries created
with the String-arg constructor. This lead to broken ZIP
archives if two different entries had the same hash code. Thanks to Anon Devs.
* COMPRESS-87: ZipArchiveInputStream could repeatedly return 0 on read() when
the archive was truncated. Thanks to Antoni Mylka.
* COMPRESS-86: Tar archive entries holding the file name for names longer
than 100 characters in GNU longfile mode didn't properly
specify they'd be using the "oldgnu" extension.
* COMPRESS-83: Delegate all read and write methods in GZip stream in order to
speed up operations.
* The ar and cpio streams now properly read and write last
modified times.
* COMPRESS-81: TarOutputStream can leave garbage at the end of the archive
Changes
-------
* COMPRESS-112: ArArchiveInputStream does not handle GNU extended filename records (//)
* COMPRESS-105: Document that the name of an ZipArchiveEntry determines whether
an entry is considered a directory or not.
If you don't use the constructor with the File argument the entry's
name must end in a "/" in order for the entry to be known as a directory.
* COMPRESS-79: Move DOS/Java time conversions into Zip utility class.
* COMPRESS-75: ZipArchiveInputStream does not show location in file
where a problem occurred.
