TurboPower Abbrevia Changelog

What's new in TurboPower Abbrevia 5.0

Dec 7, 2011
  • Features:
  • Added support for Delphi/C++Builder XE2, including the 64-bit Windows and OS X platforms.
  • Added support for FreePascal 2.4/2.6 on Windows, OS X, and Linux.
  • Added TAbTreeView and TAbListView VCL controls that provide an Explorer/WinZip-like interface, and ComCtrlsDemo Delphi example to demonstrate their usage.
  • Added ZIP64 support (reading/writing zip archives larger than 2GB, containing files larger than 2GB, or containing more than 65K files).
  • Significantly improved split/spanned zip support.
  • Added LZMA buffer-to-buffer compression/decompression (LzmaEncodeBuffer and LzmaDecodeBuffer) and compression/decompression stream descendants (TAbLZMACompressionStream and TAbLZMADecompressionStream). Thanks to Pierre le Riche.
  • Added support for tar and gzip archives containing filenames encoded in the system ANSI and OEM codepage and UTF-8. New archives are written using UTF-8.
  • Added icon/text to RAD Studio's splash screen and about box. Thanks to Lance Rasmussen.
  • Added VCL TAbProgressBar control that can replace TAbMeter.
  • Added 64-bit COM dll and support for per-user registration.
  • API Changes
  • Renamed LzEncode/LzDecode to LzmaEncodeStream/LzmaDecodeStream.
  • Renamed LzmaDecode to LzmaDecodeStream.
  • Various changes due to split/spanned zip changes (see below).
  • Bug Fixes:
  • Fixed support for opening paths with a "?" prefix.
  • Fixed buffer overflow in AbUtils.pas.
  • Fixed freshening/replacing items using absolute paths.
  • Fixed CAB files created with Delphi 2009 and later incorrectly including the "has next volume" flag.
  • Fixed Delphi 6 support. Thanks to Peter Luijer.
  • Fixed AbFindFiles so it finds system and hidden folders if the SearchAttr parameter includes them [3372355].
  • Fixed hang when trying to extract files that cross CAB boundaries when the next cab is not available [3370538].
  • Fixed extracting CAB archives so OnProcessItemFailure isn't called after a successful extraction.
  • Fixed LZMA support for streams larger than 2GB.
  • Fixed AbGetDriveFreeSpace buffer overflow and fixed support for free space larger than 2GB.
  • Fixed support for modifying SFX zips with non-native stubs (Linux on Windows and vice versa).
  • Fixed TAbBitBucketStream so it doesn't fault on writes larger than the buffer size, and supports sizes over 2GB.
  • Zip local file headers are now preserved when copying unmodified files to a new archive.
  • Local file headers are no longer copies of the central directory headers, since many of the defined extra data fields have different values in the two locations.
  • Fixed IZipKit (COM) support for enumerations (for each).
  • Split/Spanned Zip Changes
  • Bug Fixes:
  • Added support for reading/writing unequally sized spans.
  • Split/spanned zips are now written to the final location as they're compressed, rather than writing everything to a virtual memory stream first.
  • Fixed writing headers that can't be spanned so they trigger a new span if necessary.
  • API Changes:
  • Converting from an unspanned archive to a spanned one is no longer supported.
  • OnRequestImage's span numbers are now 1-based instead of 0-based to match OnRequestNthDisk.
  • OnArchiveSaveProgress is now called at the same time as OnArchiveProgress, since there isn't a lengthy copy after a spanned archive is written.
  • TAbSpanStream has been replaced by TAbSpanReadStream and TAbSpanWriteStream.

New in TurboPower Abbrevia 4.0 (Dec 7, 2011)

  • Features:
  • Added support for decompressing PKZip files created with bzip2, Lzma, PPMd and WavPack compression. Abbrevia can now read all of the .zipx compression methods besides JPEG. All libraries are statically linked.
  • Bzip2 is based on Edison Mera's Delphi wrapper for the official 1.04 SDK .c files.
  • http://edisonlife.homelinux.com/bzip2-unit/
  • http://www.bzip.org
  • Lzma is based on the official v9.20 SDK .c files (public domain).
  • http://7-zip.org/sdk.html
  • PPMd is based on Dag Ågren's Objective-C conversion of Dmitry Shkarin's original C++ PPMd variant I.1 release (public domain).
  • http://code.google.com/p/theunarchiver/
  • http://www.compression.ru/ds/
  • WavPack is based on the official v4.60.1 SDK .c files (see "WavPack License.txt").
  • http://wavpack.com/
  • Added TAbBzip2Archive that supports .bz2 archives and bzipped tars. TAbZipper, TAbUnzipper and TAbZipKit are updated to support them.
  • Added full Unicode filename support for zips and cabs.
  • When loading, zips now support UTF-8 encoding and the Info-Zip and Xceed Unicode path extra headers. ANSI or OEM encoding is detected based on the VersionMadeBy OS field and by examining the extended characters for letters that only occur in one encoding or the other.
  • When saving/renaming filenames use OEM or ANSI encoding if possible (possibly with best-fit character mapping), or fall back to UTF-8 if there are characters that don't map to the current code pages. Any filenames stored in ANSI or OEM which include extended characters are also stored using the Info-Zip Unicode path extra header.
  • CAB files now support the UTF-8 filename flag for both reading and writing. UTF-8 is always used when saving files, so filenames containing extended characters may not be compatible with older versions of Abbrevia.
  • Added support for long filenames in tar archives. Long filenames and symbolic link paths are read and written using the GNU extended headers and the UStar extension. Other extended headers (e.g., POSIX) are no longer lost when modifying a tar. Implemented by Joel Haynie, Scooter Software.
  • Added support for storing/extracting empty folders in tar archives, and improved support for them in PKZip archives.
  • Added for..in support to TAbArchiveList.
  • AbDetermineArcType can now detect archives with unknown extensions based on their content [3126055].
  • Added Stream property to TAbZipBrowse/TAbZipper/TAbUnzipper/TAbZipKit non-visual controls that can be used to load an archive from a stream instead of a file.
  • Added AbResString unit with string constants. Translations are available in Afrikaans, Dutch, French, German and Russian. Thanks to Henri Hakl, Rudy Velthuis, Hichem Bouksani, Roman Kassebaum and Pavel Koptev.
  • TAbZipView now supports themeing and exposes properties added to TCustomGrid in newer versions of Delphi (Anchors, Bevel*, DrawingStyle, GradientEndColor, GradientStartColor, Touch, OnGesture, OnMouseActivate, OnMouseEnter and OnMouseLeave). The gdsClassic DrawingStyle roughly matches the pre-Delphi 2010 appearance.
  • Added HostOS property to TAbZipItem and added more values to TAbZipHostOS enumeration based on newer AppNote.txt and Info-ZIP additions.
  • PKZip files created on Linux systems now store the Unix mode in addition to the DOS attributes.
  • Bug fixes:
  • Fixed .tar/.gz support so LastModFileDate/LastModFileTime/LastModTimeAsDateTime are all in local time, rather than UTC, and the dates are set correctly when storing and extracting files. [1327858]
  • Cab extraction errors now pass the Win32 error code to DoProcessItemFailure.
  • Fixed TAbZipView drawing when multiple rows are selected.
  • Fixed TAbZipOutline not responding to drag & drop resizing at design-time.
  • Fixed OnNeedPassword not using correct password on last try [1093711].
  • Cleanup
  • Removed support for Delphi 1-5.
  • Removed AbUnZipMemory and AbUnZipTempFile conditional defines introduced in v3.05.
  • Removed TAbMeterLink. The ItemProgressMeter/ArchiveProgressMeter properties support TAbMeter directly again.
  • Removed TAbPadLock and implicit (partial) locking while archives are busy. Use an explicit critical section if you access a single archive object from multiple threads.
  • Merged .inc files for visual controls into the VCL .pas files (e.g. AbCompnd.inc's code was moved into AbCompnd.pas). CLX versions (AbQCmpnd.pas) now include the VCL .pas file instead. This improves IDE compatibility in general, and ErrorInsight and DFM/XFM support, specifically.

New in TurboPower Abbrevia 3.05 Beta 6 (Dec 7, 2011)

  • Bug Fixes:
  • IDE hangs when closing form with TAbVCLMeterLink
  • freshing file it doesn't set the correct Item.DiskFileName
  • Impossible to unzip if basedirectory contains european chars
  • Failed unzipping of password protected files clobbers original
  • Files Extracted to Network Drives may be truncated
  • Comments:
  • In order to fix bugs [698162] and [912918] a new set of defines were added to AbDefine.inc that allow you to control the way Abbrevia extracts files. This is a temporary hack and I will be refactoring the code to make them redundant after 3.05 is released. The defines only affect AbUnZip in AbUnzPrc.pas.
  • When extracting files, we have three options:
  • Clobber - Write in place. This is the original behavior, and the side effect is that bug [698162] will reappear. If you try to overwrite a file by extracting from a password protected zip and aren't able to give the correct password the original file is deleted.
  • Memory - File is extracted to memory, and if successful is then written to disk.
  • TempFile - File is extract to the temp directory, and if successful is then moved to correct location.
  • In testing, the memory option is the fastest as long as you don't end up using the page file. Once you start to page, this option is usually (not always) slower than TempFile method. Clobber was not tested for performance, it was the original method and buggy.
  • The TempFile method is the current default behavior.
