| Apache Commons Compress RELEASE NOTES |
| |
| Apache Commons Compress software defines an API for working with |
| compression and archive formats. These include: bzip2, gzip, pack200, |
| lzma, xz, Snappy, traditional Unix Compress, DEFLATE and ar, cpio, |
| jar, tar, zip, dump, 7z, arj. |
| |
| Release 1.11 |
| ------------ |
| |
| New features: |
| o TarArchiveInputStream now supports reading global PAX headers. |
| Issue: COMPRESS-347. |
| o The PAX headers for sparse entries written by star are now |
| applied. |
| Issue: COMPRESS-346. |
| o GNU sparse files using one of the PAX formats are now |
| detected, but cannot be extracted. |
| Issue: COMPRESS-345. |
| o New method SevenZFile.getEntries can be used to list the |
| contents of a 7z archive. |
| Issue: COMPRESS-341. |
| o When using Zip64Mode.Always also use ZIP64 extensions inside |
| the central directory. |
| GitHub Pull Request #10 Thanks to Matt Hovey. |
| o ZipFile.getRawInputStream() is now part of the public API |
| Issue: COMPRESS-323. |
| o Allow byte-for-byte replication of Zip entries. |
| GitHub Pull Request #6. Thanks to Jason van Zyl. |
| o TarArchiveEntry's preserveLeadingSlashes is now a property and used |
| on later calls to setName, too. |
| This behavior is a breaking change. |
| Issue: COMPRESS-328. |
| o Added read-only support for bzip2 compression used inside of |
| ZIP archives. |
| GitHub Pull Request #4. Thanks to Sören Glimm. |
| |
| Fixed Bugs: |
| o ArArchiveInputStream can now read GNU extended names that are |
| terminated with a NUL byte rather than a linefeed. |
| Issue: COMPRESS-344. |
| o Native Memory Leak in Sevenz-DeflateDecoder. |
| Issue: COMPRESS-343. Thanks to Rene Preissel. |
| o 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. |
| o file names of tar archives using the xstar format are now |
| parsed properly. |
| Issue: COMPRESS-336. |
| o checksums of tars that pad the checksum field to the left are |
| now calculated properly. |
| Issue: COMPRESS-335. |
| o ArArchiveInputStream failed to read past the first entry when |
| BSD long names have been used. |
| Issue: COMPRESS-334. Thanks to Jeremy Gustie. |
| o Added buffering for random access which speeds up 7Z support. |
| Issue: COMPRESS-333. Thanks to Dawid Weiss. |
| o 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. |
| o SnappyCompressorInputStream and |
| FramedSnappyCompressorInputStream returned 0 at the end of the |
| stream under certain circumstances. |
| Issue: COMPRESS-332. |
| o Adjusted unit test to updates in Java8 and later that change |
| the logic of ZipEntry#getTime. |
| Issue: COMPRESS-326. |
| o 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. |
| o 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: |
| o CompressorStreamFactory can now auto-detect DEFLATE streams |
| with ZLIB header. |
| Issue: COMPRESS-316. Thanks to Nick Burch. |
| o CompressorStreamFactory can now auto-detect LZMA streams. |
| Issue: COMPRESS-313. |
| o 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. |
| o 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. |
| o 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: |
| o TarArchiveInputStream can now read entries with group or |
| user ids > 0x80000000. |
| Issue: COMPRESS-314. |
| o TarArchiveOutputStream can now write entries with group or |
| user ids > 0x80000000. |
| Issue: COMPRESS-315. |
| o TarArchiveEntry's constructor with a File and a String arg |
| didn't normalize the name. |
| Issue: COMPRESS-312. |
| o ZipEncodingHelper no longer reads system properties directly |
| to determine the default charset. |
| Issue: COMPRESS-308. |
| o BZip2CompressorInputStream#read would return -1 when asked to |
| read 0 bytes. |
| Issue: COMPRESS-309. |
| o ArchiveStreamFactory fails to pass on the encoding when creating |
| some streams. |
| * ArjArchiveInputStream |
| * CpioArchiveInputStream |
| * DumpArchiveInputStream |
| * JarArchiveInputStream |
| * TarArchiveInputStream |
| * JarArchiveOutputStream |
| Issue: COMPRESS-306. |
| o 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. |
| o 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. |
| o 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. |
| o 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. |
| o SevenZFile now throws the specific PasswordRequiredException |
| when it encounters an encrypted stream but no password has |
| been specified. |
| Issue: COMPRESS-298. |
| |
| Changes: |
| o 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. |

| Old Release Notes |
| ================= |
| |
| Release 1.9 |
| ----------- |
| |
| New features: |
| o Added support for DEFLATE streams without any gzip framing. |
| Issue: COMPRESS-263. |
| Thanks to Matthias Stevens. |
| |
| Fixed Bugs: |
| o When reading 7z files unknown file properties and properties of type |
| kDummy are now ignored. |
| Issue: COMPRESS-287. |
| o Expanding 7z archives using LZMA compression could cause an |
| EOFException. |
| Issue: COMPRESS-286. |
| o 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: |
| o 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: |
| o COMPRESS-272: CompressorStreamFactory can now auto-detect Unix compress |
| (".Z") streams. |
| |
| Fixed Bugs: |
| o COMPRESS-270: The snappy, ar and tar inputstreams might fail to read from a |
| non-buffered stream in certain cases. |
| o COMPRESS-277: IOUtils#skip might skip fewer bytes than requested even though |
| more could be read from the stream. |
| o COMPRESS-276: ArchiveStreams now validate there is a current entry before |
| reading or writing entry data. |
| o ArjArchiveInputStream#canReadEntryData tested the current |
| entry of the stream rather than its argument. |
| o COMPRESS-274: ChangeSet#delete and deleteDir now properly deal with unnamed |
| entries. |
| o COMPRESS-273: Added a few null checks to improve robustness. |
| o COMPRESS-278: TarArchiveInputStream failed to read archives with empty |
| gid/uid fields. |
| o COMPRESS-279: TarArchiveInputStream now again throws an exception when it |
| encounters a truncated archive while reading from the last |
| entry. |
| o COMPRESS-280: Adapted TarArchiveInputStream#skip to the modified |
| IOUtils#skip method. Thanks to BELUGA BEHR. |
| |
| Changes: |
| o The dependency on org.tukaani:xz is now marked as optional. |
| |
| Release 1.8 |
| ----------- |
| |
| New features: |

| metadata that can be provided via GzipParameters when writing |
| a gzip stream. |
| Issue: COMPRESS-260. |
| o SevenZOutputFile now supports chaining multiple |
| compression/encryption/filter methods and passing options to |
| the methods. |
| Issue: COMPRESS-266. |
| o The (compression) method(s) can now be specified per entry in |
| SevenZOutputFile. |
| Issue: COMPRESS-261. |
| o SevenZArchiveEntry "knows" which method(s) have been used to |
| write it to the archive. |
| Issue: COMPRESS-258. |
| o The 7z package now supports the delta filter as method. |
| o 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: |
| o BZip2CompressorInputStream read fewer bytes than possible from |
| a truncated stream. |
| Issue: COMPRESS-253. |
| o 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. |
| o CompressorStreamFactory.createCompressorInputStream with |
| explicit compression did not honor decompressConcatenated |
| Issue: COMPRESS-259. |
| o TarArchiveInputStream will now read archives created by tar |
| implementations that encode big numbers by not adding a |
| trailing NUL. |
| Issue: COMPRESS-262. |
| o 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. |
| o When writing PAX/POSIX headers for TAR entries with |
| backslashes or certain non-ASCII characters in their name |
| TarArchiveOutputStream could fail. |
| Issue: COMPRESS-265. |
| o 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: |
| o Read-Only support for Snappy compression. |
| Issue: COMPRESS-147. Thanks to BELUGA BEHR. |
| o Read-Only support for .Z compressed files. |
| Issue: COMPRESS-243. Thanks to Damjan Jovanovic. |
| o ZipFile and ZipArchiveInputStream now support reading entries |
| compressed using the SHRINKING method. Thanks to Damjan Jovanovic. |
| o 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. |
| o ZipFile and ZipArchiveInputStream now support reading entries |
| compressed using the IMPLODE method. |
| Issue: COMPRESS-115. Thanks to Emmanuel Bourg. |
| o ZipFile and the 7z file classes now implement Closeable and can be |
| used in try-with-resources constructs. |
| |
| Fixed Bugs: |
| o SevenZOutputFile#closeArchiveEntry throws an exception when using |
| LZMA2 compression on Java8. Issue: COMPRESS-241. |
| o 7z reading of big 64bit values could be wrong. |
| Issue: COMPRESS-244. Thanks to Nico Kruber. |
| o TarArchiveInputStream could fail to read an archive completely. |
| Issue: COMPRESS-245. |
| o 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. |
| o 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: |
| o 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. |
| o Added read-only support for ARJ archives that don't use |
| compression. Issue: COMPRESS-226. Thanks to Damjan Jovanovic. |
| o DumpArchiveInputStream now supports an encoding parameter that |
| can be used to specify the encoding of file names. |
| o The CPIO streams now support an encoding parameter that can be |
| used to specify the encoding of file names. |
| o Read-only support for LZMA standalone compression has been added. |
| Issue: COMPRESS-111. |
| |
| Fixed Bugs: |
| o TarBuffer.tryToConsumeSecondEOFRecord could throw a |
| NullPointerException Issue: COMPRESS-223. Thanks to Jeremy Gustie. |
| o 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. |
| o 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. |
| o 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. |
| o CpioArchiveInputStream failed to read archives created by |
| Redline RPM. Issue: COMPRESS-236. Thanks to Andrew Duffy. |
| o TarArchiveOutputStream now properly handles link names that |
| are too long to fit into a traditional TAR header. Issue: |
| COMPRESS-237. Thanks to Emmanuel Bourg. |
| o The auto-detecting create*InputStream methods of Archive and |
| CompressorStreamFactory could fail to detect the format of |
| blocking input streams. Issue: COMPRESS-239. |
| |
| Changes: |
| o Readabilty patch to TarArchiveInputStream. Issue: |
| COMPRESS-232. Thanks to BELUGA BEHR. |
| o Performance improvements to TarArchiveInputStream, in |
| particular to the skip method. Issue: COMPRESS-234. Thanks to |
| BELUGA BEHR. |
| |
| Release 1.5 |
| ----------- |
| |
| New features: |
| |
| o 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: |
| |
| o Typo in CompressorStreamFactory Javadoc |
| Issue: COMPRESS-218. |
| Thanks to Gili. |
| o ArchiveStreamFactory's tar stream detection created false positives |
| for AIFF files. |
| Issue: COMPRESS-191. |
| Thanks to Jukka Zitting. |
| o 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. |
| o 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. |
| o Writing TAR PAX headers failed if the generated entry name ended |
| with a "/". |
| Issue: COMPRESS-203. |
| o 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. |
| o TarArchiveInputStream ignored the encoding for GNU long name |
| entries. |
| Issue: COMPRESS-212. |
| o TarArchiveInputStream could leave the second EOF record inside the |
| stream it had just finished reading. |
| Issue: COMPRESS-206. |
| Thanks to Peter De Maeyer. |
| o DumpArchiveInputStream no longer implicitly closes the original |
| input stream when it reaches the end of the archive. |
| o ZipArchiveInputStream now consumes the remainder of the archive when |
| getNextZipEntry returns null. |
| o Unit tests could fail if the source tree was checked out to a |
| directory tree containign spaces. |
| Issue: COMPRESS-205. |
| Thanks to Daniel Lowe. |
| o Fixed a potential ArrayIndexOutOfBoundsException when reading STORED |
| entries from ZipArchiveInputStream. |
| Issue: COMPRESS-219. |
| o CompressorStreamFactory can now be used without XZ for Java being |
| available. |
| Issue: COMPRESS-221. |
| |
| Changes: |
| |
| o Improved exception message if a zip archive cannot be read because |
| of an unsupported compression method. |
| Issue: COMPRESS-188. |
| Thanks to Harald Kuhn. |
| o ArchiveStreamFactory has a setting for file name encoding that sets |
| up encoding for ZIP and TAR streams. |
| Issue: COMPRESS-192. |
| Thanks to Jukka Zitting. |
| o TarArchiveEntry now has a method to verify its checksum. |
| Issue: COMPRESS-191. |
| Thanks to Jukka Zitting. |
| o Split/spanned ZIP archives are now properly detected by |
| ArchiveStreamFactory but will cause an |
| UnsupportedZipFeatureException when read. |
| o 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. |
| o TarArchiveEntry has a new constructor that allows setting linkFlag |
| and preserveLeadingSlashes at the same time. |
| Issue: COMPRESS-201. |
| o ChangeSetPerformer has a new perform overload that uses a ZipFile |
| instance as input. |
| Issue: COMPRESS-159. |
| o Garbage collection pressure has been reduced by reusing temporary |
| byte arrays in classes. |
| Issue: COMPRESS-172. |
| Thanks to Thomas Mair. |
| o Can now handle zip extra field 0x5455 - Extended Timestamp. |
| Issue: COMPRESS-210. |
| Thanks to Julius Davies. |
| o handle zip extra field 0x7875 - Info Zip New Unix Extra Field. |
| Issue: COMPRESS-211. |
| Thanks to Julius Davies. |
| o ZipShort, ZipLong, ZipEightByteInteger should implement Serializable |
| Issue: COMPRESS-213. |
| Thanks to Julius Davies. |
| o better support for unix symlinks in ZipFile entries. |
| Issue: COMPRESS-214. |
| Thanks to Julius Davies. |
| o ZipFile's initialization has been improved for non-Zip64 archives. |
| Issue: COMPRESS-215. |
| Thanks to Robin Power. |
| o 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 |
| http://commons.apache.org/proper/commons-compress/security.html#Fixed_in_Apache_Commons_Compress_1.4.1 |
| |
| Fixed Bugs: |
| |
| o Ported libbzip2's fallback sort algorithm to |
| BZip2CompressorOutputStream to speed up compression in certain |
| edge cases. |
| |
| Release 1.4 |
| ----------- |
| |
| New features: |
| o COMPRESS-156: Support for the XZ format has been added. |
| |
| Fixed Bugs: |
| o 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. |
| o COMPRESS-184: TarArchiveInputStream failed to parse PAX headers that |
| contained non-ASCII characters. |
| o COMPRESS-178: TarArchiveInputStream throws IllegalArgumentException instead of IOException |
| o COMPRESS-179: TarUtils.formatLongOctalOrBinaryBytes() assumes the field will be 12 bytes long |
| o COMPRESS-175: GNU Tar sometimes uses binary encoding for UID and GID |
| o COMPRESS-171: ArchiveStreamFactory.createArchiveInputStream would claim |
| short text files were TAR archives. |
| o COMPRESS-164: ZipFile didn't work properly for archives using unicode extra |
| fields rather than UTF-8 filenames and the EFS-Flag. |
| o 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: |
| o 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. |
| o COMPRESS-181: Added a workaround for a Bug some tar implementations that add |
| a NUL byte as first byte in numeric header fields. |
| o COMPRESS-176: Added a workaround for a Bug in WinZIP which uses backslashes |
| as path separators in Unicode Extra Fields. |
| o COMPRESS-131: ArrayOutOfBounds while decompressing bz2. Added test case - code already seems to have been fixed. |
| o COMPRESS-146: BZip2CompressorInputStream now optionally supports reading of |
| concatenated .bz2 files. |
| o COMPRESS-154: GZipCompressorInputStream now optionally supports reading of |
| concatenated .gz files. |
| o 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. |
| o 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. |
| o 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: |
| o Support for the Pack200 format has been added. Issue: COMPRESS-142. |
| o Read-only support for the format used by the Unix dump(8) tool |
| has been added. Issue: COMPRESS-132. |
| |
| Fixed Bugs: |
| o BZip2CompressorInputStream's getBytesRead method always |
| returned 0. |
| o ZipArchiveInputStream and ZipArchiveOutputStream could leak |
| resources on some JDKs. Issue: COMPRESS-152. |
| o TarArchiveOutputStream's getBytesWritten method didn't count |
| correctly. Issue: COMPRESS-160. |
| |
| Changes: |
| o The ZIP package now supports Zip64 extensions. Issue: COMPRESS-36. |
| o 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: |
| o 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. |
| o 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: |
| o COMPRESS-129: ZipArchiveInputStream could fail with a "Truncated ZIP" error |
| message for entries between 2 GByte and 4 GByte in size. |
| o COMPRESS-145: TarArchiveInputStream now detects sparse entries using the |
| oldgnu format and properly reports it cannot extract their |
| contents. |
| o COMPRESS-130: The Javadoc for ZipArchiveInputStream#skip now matches the |
| implementation, the code has been made more defensive. |
| o COMPRESS-140: ArArchiveInputStream fails if entries contain only blanks for |
| userId or groupId. Thanks to Trejkaz. |
| o COMPRESS-139: ZipFile may leak resources on some JDKs. |
| o COMPRESS-125: BZip2CompressorInputStream throws IOException if |
| underlying stream returns available() == 0. |
| Removed the check. |
| o COMPRESS-127: Calling close() on inputStream returned by |
| CompressorStreamFactory.createCompressorInputStream() |
| does not close the underlying input stream. |
| o COMPRESS-119: TarArchiveOutputStream#finish now writes all buffered |
| data to the stream |

| Changes: |
| o ZipFile now implements finalize which closes the underlying |
| file. |
| o COMPRESS-117: Certain tar files not recognised by |
| ArchiveStreamFactory. |
| |
| Release 1.1 |
| ----------- |
| |
| New features: |
| o COMPRESS-108: Command-line interface to list archive contents. |
| Usage: java -jar commons-compress-n.m.jar archive-name [zip|tar|etc] |
| o COMPRESS-109: Tar implementation does not support Pax headers |
| Added support for reading pax headers. |
| Note: does not support global pax headers |
| o 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. |
| o 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). |
| o 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. |
| o 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. |
| o COMPRESS-89: The ZIP classes now detect encrypted entries. |
| o COMPRESS-97: Added autodetection of compression format to |
| CompressorStreamFactory. |
| o COMPRESS-95: Improve ExceptionMessages in ArchiveStreamFactory Thanks to Joerg Bellmann. |
| o 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. |
| o ArchiveEntry now has a getLastModifiedDate method. |
| o COMPRESS-78: Add a BZip2Utils class modelled after GZipUtils Thanks to Jukka Zitting. |
| |
| Fixed Bugs: |
| o COMPRESS-72: Move acknowledgements from NOTICE to README |
| o COMPRESS-113: TarArchiveEntry.parseTarHeader() includes the trailing space/NUL when parsing the octal size |
| o COMPRESS-118: TarUtils.parseName does not properly handle characters outside the range 0-127 |
| o COMPRESS-107: ArchiveStreamFactory does not recognise tar files created by Ant |
| o COMPRESS-110: Support "ustar" prefix field, which is used when file paths are longer |
| than 100 characters. |
| o 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. |
| o COMPRESS-101: ZipArchiveInputStream should now properly read archives that |
| use data descriptors but without the "unofficial" signature. |
| o COMPRESS-74: ZipArchiveInputStream failed to update the number of bytes |
| read properly. |
| o 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. |
| o 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. |
| o COMPRESS-73: ZipArchiveEntry, ZipFile and ZipArchiveInputStream are now |
| more lenient when parsing extra fields. |
| o COMPRESS-82: cpio is terribly slow. |
| Documented that buffered streams are needed for performance |
| o Improved exception message if the extra field data in ZIP |
| archives cannot be parsed. |
| o COMPRESS-17: Tar format unspecified - current support documented. |
| o 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. |
| o COMPRESS-87: ZipArchiveInputStream could repeatedly return 0 on read() when |
| the archive was truncated. Thanks to Antoni Mylka. |
| o 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. |
| o COMPRESS-83: Delegate all read and write methods in GZip stream in order to |
| speed up operations. |
| o The ar and cpio streams now properly read and write last |
| modified times. |
| o COMPRESS-81: TarOutputStream can leave garbage at the end of the archive |
| |
| Changes: |
| o COMPRESS-112: ArArchiveInputStream does not handle GNU extended filename records (//) |
| o 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. |
| o COMPRESS-79: Move DOS/Java time conversions into Zip utility class. |
| o COMPRESS-75: ZipArchiveInputStream does not show location in file |
| where a problem occurred. |
