|
|
- updated pom.xml to delete "souceDirectory"
|
|
No need to specify sourceDirectory if the project follows maven
|
|
standard.
|
|
- updated configurations to use sbt 0.11.1
|
|
|
|
|
|
Changes since version 1.0.7:
|
|
- supported some new functionalities, which have been introduced since 'zlib' 1.2.
|
|
- JZlib#{adler32,crc32}_combine,
|
|
- JZlib can handle gzip file format(RFC1952).
|
|
- added following classes,
|
|
- DeflaterOutputStream
|
|
- InflaterInputStream
|
|
- GZIPOutputStream
|
|
- GZIPInputStream
|
|
- Inflater
|
|
- Deflater
|
|
- ZStream has been deprecated.
|
|
Use Inflater and Deflater instead of it.
|
|
- GZIPHeader
|
|
- re-implemented Z{Input,Output}Stream with {Deflater,Inflater}{I/O}Stream
|
|
- those classes have been deprecated.
|
|
Use DeflaterOutputStream and InfaterInputStream instead of them.
|
|
- com/ -> src/main/java/com/
|
|
- some tests under src/test/scala/
|
|
- pom.xml for mvn, and projects/ for sbt.
|
|
|
|
|
|
Changes since version 1.0.6:
|
|
- change: memory and performance optimisations in the inflate operation.
|
|
- change: added the nowrap argument to Z{Input,Output}?Stream.
|
|
|
|
|
|
Changes since version 1.0.5:
|
|
- ZInputStream.read(byte[], int, int) method return sometimes zero
|
|
instead of -1 at the end of stream.
|
|
- ZOutputStream.end() method should not declare IOException.
|
|
- It should be possible to call ZOutputStream.end() method more times
|
|
(because you can call close() method and after it end() method in
|
|
finally block).
|
|
- ZOutputStream.finish() method should not ignore IOException from flush().
|
|
Many thanks to Matej Kraus at seznam.cz , who pointed out above problems.
|
|
|
|
|
|
Changes since version 1.0.4:
|
|
- a minor bug fix in ZInputStream
|
|
|
|
|
|
Changes since version 1.0.3:
|
|
- fixed a bug in closing ZOutputStream.
|
|
The inflating and deflating processes were not finished successfully.
|
|
- added 'finish' and 'end' methods to ZOutputStream.java
|
|
- added 'example/test_stream_deflate_inflate.java'
|
|
|
|
|
|
Changes since version 1.0.2:
|
|
- enabled pure Java implementation of adler32 and
|
|
commented out the dependency on J2SE in Adler32.java for J2ME users.
|
|
|
|
|
|
Changes since version 1.0.1:
|
|
- fixed a bug in deflating some trivial data, for example,
|
|
large data chunk filled with zero.
|
|
- added 'version' method to JZlib class.
|
|
|
|
|
|
Changes since version 1.0.0:
|
|
- added ZInputStream and ZOutputStream classes.
|
|
- fixed a typo in LICENSE.txt.
|
|
|
|
|
|
Changes since version 0.0.9:
|
|
- fixed a bug in setting a dictionary in the inflation process.
|
|
- The license was changed to a BSD style license.
|
|
- Z{Input,Output}Stream classes were deleted.
|
|
|
|
|
|
Changes since version 0.0.8:
|
|
- fixed a bug in handling a preset dictionary in the inflation process.
|
|
|
|
|
|
Changes since version 0.0.7:
|
|
- added methods to control the window size (the size of the history
|
|
buffer) and to handle the no-wrap option (no zlib header or check),
|
|
which is the undocumented functionality of zlib.
|
|
|
|
|
|
Changes since version 0.0.6:
|
|
- updated InfBlocks.java as zlib did to fix the vulnerability related to
|
|
the 'double free'. Of course, JZlib is free from such a vulnerability
|
|
like the 'double free', but JZlib had crashed with NullPointerException
|
|
by a specially-crafted block of invalid deflated data.
|
|
|
|
|
|
Changes since version 0.0.5:
|
|
- added 'flush()' method to com.jcraft.jzlib.ZOutputStream.
|
|
- fixed to take care when occurring the buffer overflow in
|
|
com.jcraft.jzlib.ZOutputStream.
|
|
Many thanks to Tim Bendfelt at cs.wisc.edu , who pointed out above problems.
|
|
|
|
|
|
Changes since version 0.0.4:
|
|
............................
|
|
- fixed a bug in Adler32 class.
|
|
- fixed a bug in ZInputStream class
|
|
- modified ZInputStream to be extended from InputStream
|
|
instead of FileInputStream.
|
|
- modified ZOutputStream to be extended from OutputStream
|
|
instead of FileOutputStream.
|
|
- modified ZStream to be changeable wbits. Give wbits value to
|
|
the method 'deflateInit' of ZStream.
|
|
Many thanks to Bryan Keller<keller@neomar.com>, who reported bugs
|
|
and made suggestions.
|
|
|
|
|
|
Changes since version 0.0.3:
|
|
............................
|
|
- fixed a bug in the compression level 0.
|
|
- modified to be compatible with JIKES's bug.
|
|
- added Z[Input,Output]Stream written by Lapo Luchini<lapo@lapo.it>.
|
|
|
|
|
|
Changes since version 0.0.2:
|
|
............................
|
|
- fixed a critical bug, which had arisen in the deflating operation with
|
|
NO_FLUSH and DEFAULT_COMPRESSION mode.
|
|
Many thanks to Bryan Keller(keller@neomar.com), who reported this glitch.
|
|
|
|
|
|
Changes since version 0.0.1:
|
|
............................
|
|
- fixed the bad compression ratio problem, which is reported from
|
|
Martin Smith(martin@spamcop.net). The compression ratio was not so good
|
|
compared with the compression ration of zlib. Now, this problem has been
|
|
fixed and, I hope, that deflated files by JZlib and zlib are completely
|
|
same bit by bit.
