DotNetZip

This is a bugfix release for v1.9. Status: The binaries here are near final. All of the bugs listed here are fixed in these binaries. I've run the test suite and everything passes. This release has these downloads: ... [More] DotNetZipLib-DevKit-v1.9.zip - This is probably what you want. This is a binary release, that includes of the signed DLLs for Zip and Zlib, for desktop and Compact Framework; the XML Documentation file for intellisense; the help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library. DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities. DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library. DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses. DotNetZipUtils-v1.9.zip - a set of exe tools (command-line and GUI) that rely on the library, to create and manage zip files. Download this if you want finished user-level tools to manipulate zip files. (A replacement for WinZip) DotNetZipUtils-v1.9.msi - an installer for Windows for the Zip utilities that utilize the library. This is the same stuff as the DotNetZipUtils-v1.9.zip, but in MSI form. It optionally sets up file associations, guides you through the install. DotNetZip-Runtime-v1.9.msi - an installer for the runtime. DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats. Notable: the quality/reliability of the code is much higher than for v1.9.1.5 - many bug fixes. New bzip2.exe tool, and a gzip.exe tool. Silverlight DLLs for ZIP, ZLIB or BZIP2 are included The helpfile still needs work The version numbers for these preliminary DLLs is currently v1.9.1.6006 The minimum requirement for the binaries is (as in prior releases of DotNetZip) .NET 2.0 or later. To build the source you need VS2010 and .NET 4.0. Try it out and give me feedback. But make it fast: I hope to get the final v1.9.1.6 out very soon. Bugs fixed in this release: Saving to a Stream using Encryption corrupts the output file Exception when creating split archive ZipOutputStream corrupts data buffer when calling Write(byte[],int,int) Trying to zip the root zips the current working directory instead ZipInputStream throws NullReferenceException when using ZipEntry.Extract() NullRereferenceException when extracting Array out of bounds exception in finish() doc for ZipEntry.IsText property should be clearer and more complete Errors with Duplicate Entries Select does not work with forward slashes Possible bug in ZlibStream FileNotFoundException when creating a Self Extracting Zip file Malformed zip file should throw ZipException or BadReadException, not IOException Ensure consistency on exceptions on ZipFile.Read() failure.

This is a bugfix release for v1.9.Status: The binaries here are preliminary. All of the bugs listed here are fixed in these binaries. I've run the test suite and everything passes. This release has these downloads: DotNetZipLib-DevKit-v1.9.zip - ... [More] This is probably what you want. This is a binary release, that includes of the signed DLLs for Zip and Zlib, for desktop and Compact Framework; the XML Documentation file for intellisense; the help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library. DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities. DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the License. Download this if you want to distribute .NET applications that use the Zip library, or if you want to run a .NET application that depends on this library. DotNetZipUtils-v1.9.zip - a set of exe tools (command-line and GUI) that rely on the library, to create and manage zip files. Download this if you want finished user-level tools to manipulate zip files. (A replacement for WinZip) DotNetZipUtils-v1.9.msi - an installer for Windows for the Zip utilities that utilize the library. This is the same stuff as the DotNetZipUtils-v1.9.zip, but in MSI form. It optionally sets up file associations, guides you through the install. DotNetZip-Runtime-v1.9.msi - an installer for the runtime. DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats. Notable: the quality/reliability of the code is higher than for v1.9.1.5 - many bug fixes. New bzip2.exe tool, and a gzip.exe tool. No Silverlight ZIP DLL, yet? Silverlight DLLs for ZLIB/Deflate/GZIP and BZip2. The help/documentation is a little rough The version numbers for these preliminary DLLs is currently v1.9.1.6005 The minimum requirement for the binaries is (as in prior releases of DotNetZip) .NET 2.0 or later. To build the source you need VS2010 and .NET 4.0. Try it out and give me feedback. But make it fast: I hope to get the final v1.9.1.6 out very soon. Bugs fixed in this release:Saving to a Stream using Encryption corrupts the output fileException when creating split archiveZipOutputStream corrupts data buffer when calling Write(byte[],int,int)Trying to zip the root zips the current working directory insteadZipInputStream throws NullReferenceException when using ZipEntry.Extract()NullRereferenceException when extractingArray out of bounds exception in finish()doc for ZipEntry.IsText property should be clearer and more completeErrors with Duplicate EntriesSelect does not work with forward slashesPossible bug in ZlibStreamFileNotFoundException when creating a Self Extracting Zip fileMalformed zip file should throw ZipException or BadReadException, not IOExceptionEnsure consistency on exceptions on ZipFile.Read() failure.Compression roundtrip problem - Adler32 is incorrectSelf Extracting Archive and file removalUsing ZipInputStream with ZipEntry.OpenReader() gives a "Bad Signature" errorSetting Entry._Source to "None" after Save Causes Exceptions in Later OperationsFileSelector: AddSelectedFiles forced downcase{Add/Update}SelectedFiles downcases folder namesExtractSelectedEntries breaks for filenames that include parensSfx Copyright Option not working as expectedZipFile fails to find entry by NameZipFile.Read does not preserve unicode filenames (with workaround)FileNotFoundException when creating a Self Extracting Zip fileBOM in file contrary to the behavior described by the documentationWriting zero bytes to a ZipOutputStream causes exceptionIncorrect decoding of the comment in ZipFile.Read() method.Fix the use of Exceptions in PDOSInclude the License for ZLIB in the binary distributionsWriting zero bytes to a ZipOutputStream causes exceptionString Indexer on ZipFile fails to find the entry by nameTools/WinFormApp does not correctly create split archivesCRC32CalculatorStream CanSeek property flawEncoding is not honored by ZipOutputStream.PutNextEntry methodZipOutputStream comment NullReferenceExceptionTurn off Criterion TracingDon't use hardcoded filename length in ZipEntry.Write.cs - Unicode filenames, max pathSave to the input stream should not be allowed.VersionNeededToExtract causes .NET System.IO.Zip to fail readCloseDelegate can be called twiceAny error causes ZipException, not just invalid file formatsFile handles persist after calling Dispose() when extracting spanned ZIPMulti-Span Zips not closing after ZipFile disposalFile not found when compressing zipped file into spanned archiveCan't delete .z01 file after extraction of multi-segment archiveSplitting Large (~1gb+) files leads to an exceptionextracting zip with several segments, cannot delete .zip file afterwardsCreating a split archive does not close intermediate streamsAllow a way to specify upper limit of # threads used for compressingBug when compressing .rar or .zip fileZipErrorAction.Skip is not honored when using nonseekable output stream, and File.Open failsPoor performance when reading large ZIP filesSetting EncryptionAlgorithm.None after setting password results in an encrypted zipPoor memory performance when adding filesThe MAC does not matchSave a Spanned Zip after reading an existing ZipFileNew features in the binary for this release (all these features are minor):Add BZip2 compression capability to the libraryAdd a CheckZipPassword static method to ZipFile classexpose CountingStream as a public typecreating an SFX should allow an option to set the title of the extractor windowCannot cancel within AddProgress eventProvide a way to Force UTF-8 (or whatever the alternate encoding is) in filenamesnew source features:Upgrade the source to VS2010Add InfoZip compatibility tests to the test sourceConvert setup to Wix projects [Less]
