Bit7z v4.0.0

Changes from v4.0.0-rc:

• Use macro instead of function for HRESULT_FROM_WIN32 (by @michaelKle in #130).
• Fixed missing #include <algorithm> in formatdetect.cpp (by @gr3yknigh1 in #132).
• Fixed code formatting, code style consistency, and comments.
• Fixed support to GCC 4.9.
• Improved unit tests.
• Added unit tests for BitItemsVector.
• Added tests for BitArchiveReader.
• Made the fs namespace internal to the bit7z namespace (fix #141).
• Increased the number of open files when creating multi-volume archives (partial fix for issue #150).
• Improved error messages.
• Removed createArchiveObject in Bit7zLibrary.
• 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).
  • Alternatively, you can specify a custom path containing the 7-zip source code via the option BIT7Z_CUSTOM_7ZIP_PATH.
• Fixed and improved the handling of UTF-8 paths.
• Improve format detection.
• Added option BIT7Z_USE_SYSTEM_CODEPAGE to make bit7z use the system codepage for std::string instead of UTF-8 (highly not recommended).
• Added functions to check whether an archive is encrypted/header-encrypted (issue #164).
• Removed unnecessary conversions from fs::path to tstring and vice versa.
• Added support for correctly storing symbolic links when creating archives (discussion #166).
• Added support for applying BIT7Z_STRING to macro defines (issue #167).
• Added optional sanitization of reserved Windows file names during file extraction (by @Luosiyuan in #168).
• Improved the README.
• Check for the file signature when detecting the format of files w/o an extension.
• Improved error messages when extracting an encrypted archive w/o a password.
• Introduced BitFailureSource error condition enum: it can be used for performing queries on bit7z's std::error_codes, for the purpose of grouping, classification, or error translation.

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).
