Bit7z v4.0.8

Changes from v4.0.7:

• Fixed missing header (gcc14) (by @SGSSGene in #218).
• Fixed build failing when cross-compiling using MinGW on Linux (closed issue #222).
• Fixed conversion from FILETIME to file_time_type when using libstdc++.
• Rewrote directory indexing algorithm to not use recursion (closed issue #223).
  • This fixes possible stack overflow errors that could happen while indexing deeply nested directory structures.
• Optimized BitArchiveReader::items().
• Optimized indexing of directories.
• Disabled buffering of file streams to improve performance (issue #224).
  • Now bit7z is considerably faster while reading and writing files during extraction and compression operations.
  • For example, this graph shows the improvement in the runtime of a test program between v4.0.7 and v4.0.8:
    
  • There is still some overhead compared to 7-zip which will require some more work. I plan to remove it for the next version v4.1.
• Fixed support for BSD operating systems (closed issue #230).
• Added BitOutputArchive::addDirectoryContents and BitFileCompressor::compressDirectoryContents methods (closed issue #226).

Bit7z v4.0.7

Changes from v4.0.6:

• Fixed missing conversion from tstring to path in BitItemsVector::indexPaths (closes #199).
• Updated project version in CMakeLists.txt.
• Fixed GitHub actions.
• Added nativePath() method to BitArchiveItem.
• Added support for recursively deleting the content of folder items within archives.
  • Previously, BitArchiveEditor could only delete the metadata of the folder, not its content.

    // Deleting all the content of the "folder".
    // Note: if no policy is passed, the method will still use the old behavior.
    editor.deleteItem("folder", DeletePolicy::RecurseDirs);

• Fixed BitOutputArchive::addFiles overloads.
  • Previously, the method overload prevented you from using the method's default arguments.
  • Now you can, for example, pass only one argument:

    // Adds all the files within the given path, recursively including the ones inside subfolders.
    // Previously, you had to explicitly do archive.addFiles("directory/path/", "*", true);
    archive.addFiles("directory/path/"); 

• Optimized BitArchiveReader::items().
  • From my tests, now the method is on average ~25% faster than before.
• Added missing headers in bit7z.hpp.
• Updated minimum required version of CMake.
• Improved and updated the README.

Changes from v4.0.4:

• Fixed building using some versions of GCC.
• Fixed building using GCC on macOS.
• Fixed a missing nullptr check when extracting to a fixed-size buffer.
• Fixed the empty name file alias not being used in some edge cases.
• Added a check for invalid indices in BitInputArchive::extractTo.
• Avoided the unnecessary creation of a FilesystemItem object in OpenCallback.
• Added the option BIT7Z_DISABLE_USE_STD_FILESYSTEM, which makes bit7z always use ghc::filesystem instead of std::filesystem.
  • This option allows you to work around any possible bug in compilers' implementation of std::filesystem (e.g., #181).
  • By default, this option is disabled, and bit7z will always try to use std::filesystem when available (as in previous versions).
• Fixed the std::copy_n warning in old versions of MSVC.
• Defined /Zc:__cplusplus only when using MSVC 15.7 and later.
• Updated examples in the README.

• Added a check if the password is ASCII-only when compressing to Zip archives (it can be disabled via the BIT7Z_DISABLE_ZIP_ASCII_PWD_CHECK CMake option).
• Updated default version of 7-zip to v23.01.
• Fixed build with MSVC ARM toolchain.
• Removed third-party git submodules: now bit7z uses CPM.cmake for automatically handling third-party dependencies.
  • By default, bit7z will use 7-zip v23.01, unless you specify a different version via the BIT7Z_7ZIP_VERSION option (e.g., -DBIT7Z_7ZIP_VERSION=22.01).

Changes from v3.2.x:

Expand for more details!

• Added support to Linux and macOS (issue #19).
• Added support to the MinGW compiler.
• Dropped support to old MSVC 2012 and 2013.
• The project requires at least a C++14 compiler to build; the public API is still C++11-compatible.
• Removed QMake and MSBuild project files: now bit7z uses only CMake as its build system.
• Removed format restriction to memory compression.
• Renamed BitArchiveInfo to BitArchiveReader.
• Added support to extracting/testing the input archive of BitArchiveReader.
• Made BitArchiveReader/BitInputArchive behave like an std container (e.g., added iterators).
• Added support for canceling ongoing operation in progress callback (issue #37).
• Added support to set the number of threads used when compressing (issue #38).
• Added support for extracting without retaining the directory structure (issue #34).
• Added the possibility to choose the word size to use when compressing.
• Added the BitArchiveWriter class that allows creating a single new archive or updating an old one with new items.
• Added the BitArchiveEditor class that allows editing existing archives.
  • Added support for renaming/deleting items inside an archive (issue #43).
• Added different archive update modes:
  • None: Trying to update and archive will throw a BitException.
  • Append: New items will be appended to the archive (i.e., the old update behavior).
  • Overwrite: New items whose path already exists in the archive will be overwritten, and others will be appended.
• Changed file callback to make it report the full path of the file (issue #46).
• Added the possibility to extract a specific file to buffer (issue #32).
• Fixed and improve the public API.
• Renamed the BitExtractor class to BitFileExtractor.
  • Now, BitExtractor is just a template class for all the extraction classes.
• Renamed the BitCompressor class to BitFileCompressor.
  • Now, BitCompressor is just a template class for all the compression classes.
• Changed the default string type to std::string instead of std::wstring.
  • std::strings are considered UTF-8 encoded: the project will follow the UTF-8 Everywhere Manifesto.
  • This allows using the library in cross-platform projects more quickly.
  • You can still achieve the old behavior by using bit7z with the -DBIT7Z_USE_NATIVE_STRING CMake option. In this case:
    • On Windows, the default string type will be std::wstring (as in bit7z v3);
    • On Linux and macOS, it will remain std::string.
• Added an initial unit test subproject (can be enabled via the BIT7Z_BUILD_TESTS option).
• Fixed some edge cases in the wildcard matching function.
• Added a basic OverwriteMode enum that allows configuring how to deal with when an output file or buffer already exists (issue #116). It works for both compressors and extractors.
  • None: The archive handler will throw an exception.
  • Overwrite: The handler will overwrite the old file or buffer with the new one.
  • Skip: The handler will skip writing to the output file or buffer.
• Added a getter for the CRC value of a BitArchiveItem.
• Added option for generating Position Independent Code (issue #117).
• Allow setting archive format properties as described in the 7-zip docs (close issues #91 and #103).
• Moved public API headers to the include/bit7z/ folder.
• Added an option to automatically prepend paths with the long path prefix (issue #45).
• Added an option to build the Doxygen documentation.
• Clean up code and fix code formatting.
• Re-licensed the project under the MPLv2 (issue #86).
