Changelog of @hackage/zip-archive 0.4.2.1

zip-archive 0.4.2.1

  • Fix Windows build regression (#61).

zip-archive 0.4.2

  • Fix problem with files with colon (#89).
  • Remove build-tools. This was used to indicate that the 'unzip' executable was needed for testing, but it was never intended to be used this way and now the field is deprecated. The current test suite simply skips the test using the unzip executable (with a warning) if 'unzip' is not in the path.
  • Remove existing symlinks when extracting zip files with symlinks (#60, Vikrem). Previously, writeEntry would raise an error if it tried to create a symlink and a symlink already existed at that path. This behavior was inconsistent with its behavior for regular files, which it overwrote without comment. This commit causes symlinks to be replaced by writeEntry instead of an error being raised.
  • Remove binary < 0.6 CPP. It's no longer needed because we don't support binary < 0.6. Also use manySig instead of many, to get better error messages.
  • Add type annotation for printf.
  • Better checking for unsafe paths (#55). This method allows things like foo/bar/../../baz.
  • Require base >= 4.5 (#56)
  • Add GitHub CI.

zip-archive 0.4.1

  • writEntry behavior change: Improve raising of UnsafePath error (#55). Previously we raised this error spuriously when archives were unpacked outside the working directory. Now we raise it if eRelativePath contains ".." as a path component, or eRelativePath path is an absolute path and there is no separate destination directory. (Note that /foo/bar is fine as a path as long as a destination directory, e.g. /usr/local, is specified.)

zip-archive 0.4

  • Implement read-only support for PKWARE encryption (Sergii Rudchenko). The "traditional" PKWARE encryption is a symmetric encryption algorithm described in zip format specification in section 6.1. This change allows to extract basic "password-protected" entries from ZIP files. Note that the standard file extraction function extractFilesFromArchive does not decrypt entries (it will raise an exception if it encounters an encrypted entry). To handle archives with encrypted entries, use the new function fromEncryptedEntry.

    API changes:

    • Add eEncryptionMethod field to Entry.
    • Add EncryptionMethod type.
    • Add function isEncryptedEntry.
    • Add function fromEncryptedEntry.
    • Add CannotWriteEncryptedEntry constructor to ZipException.

  • Add UnsafePath to ZipException (#50).

  • writeEntry: raise UnsafePath exception for unsafe paths (#50). This prevents malicious zip files from overwriting paths above the working directory.

  • Add Paths_zip_archive to autogen-modules.

  • Clarify README and cabal description.

  • Specify cabal-version: 2.0. Otherwise we get an unknown build tool error using build-depends without a custom Setup.hs.

  • Change build-type to simple. Retain 'build-tools: unzip' in test stanza, though now it doesn't do anything except give a hint to external tools. If unzip is not found in the path, the test suite prints a message and counts the test that requires unzip as succeeding (see #51).

zip-archive 0.3.3

  • Remove dependency on old-time (typedrat).
  • Drop splitBase flag and support for base versions < 3.

zip-archive 0.3.2.5

  • Move 'build-tools: unzip' from library stanza to test stanza. unzip should only be required for testing, not for regular builds of the library.

zip-archive 0.3.2.4

  • Make build-tools stanza conditional on non-windows. Closes #44.

zip-archive 0.3.2.3

  • Use custom-setup stanza and specify build-tools. Closes #41.

zip-archive 0.3.2.2

  • Use createSymbolicLink instead of createFileLink in tests. This allows us to lower the directory lower bound (#40).

zip-archive 0.3.2.1

  • Fixes for handling of symbolic links (#39, Tommaso Piazza).

  • Fixes for symbolic link tests, and additional tests.

zip-archive 0.3.2

  • Add ZipOption to preserve symbolic links (#37, Tommaso Piazza). Add OptPreserveSymbolicLinks constructor to ZipOption. If this option is set, symbolic links will be preserved. Symbolic links are not supported on Windows.

  • Require binary >= 0.6 (#36).

  • Improve exit handling in zip-archive program.

zip-archive 0.3.1.1

  • readEntry: Read file as a strict ByteString. This avoids problems on Windows, where the file handle wasn't being closed.
  • Added appveyor.yml to do continuous testing on Windows.
  • Test suite: remove need for external zip program (#35). Instead of creating an archive with zip, we now store a small externally created zip archive to use for testing.

zip-archive 0.3.1

  • Don't use a custom build (#28).
  • Renamed executable Zip -> zip-archive, added --debug option. The --debug option prints the intermediate Haskell data structure.

zip-archive 0.3.0.7

  • Fix check for unix file attributes (#34). Previously attributes would not always be preserved for files in zip archives.

zip-archive 0.3.0.6

  • Bump bytestring lower bound so toStrict is guaranteed (Benjamin Landers).

zip-archive 0.3.0.5

  • Fix bug in OptLocation handling (EugeneN). When using OptLocation folder False (for adding files to an archive into a folder without preserving full path hierarchy), original files' names were ignored, resulting in all the files getting the same name.

zip-archive 0.3.0.4

  • Fix toArchive so it doesn't use too much memory when a data data descriptor holds the size (Michael Stahl, #29). The size fields in the local file headers may not contain valid values, in which case the sizes are stored in a "data descriptor" that follows the file data. Previously handling this case required reading the entire archive is a [Word8] list. With this change, getWordsTilSig iteratively reads chunks as strict ByteStrings and converts them to a lazy ByteString at the end.

zip-archive 0.3.0.3

  • Test suite: use withTempDir to create temporary directory. This should help fix problems some have encountered with the test suite leaving a temporary directory behind.

zip-archive 0.3.0.2

  • Fix test suite so it runs on Windows.
  • Zip executable: get version from cabal Paths_zip_archive (#27).

zip-archive 0.3.0.1

  • Set eVersionMadeBy to 0 (default) in toEntry, since we are setting external attributes to 0. See jgm/pandoc#2822. Only to eVersionMadeBy to UNIX if we actually read file attributes on a UNIX system.

zip-archive 0.3

  • Support preservation of file modes on Posix (Dan Aloni, #26).
  • Add eVersionMadeBy field to Entry (API change).
  • Export ZipException (API change).
  • fromEntry no longer checks for CRC32 match. Previously, it issued error if the match failed. CRC32 match is now checked in writeEntry instead, and a CRC32Exception is raised if the checksum doesn't match.
  • Test suite: return nonzero status if there are test failures. Previously we mistakenly did this only on 'errors', not failures.
  • Test suite: don't use -9 with zip as it isn't always available.
  • Use .travis.yml that builds on both stack and cabal.

zip-archive 0.2.3.7

  • Declared test suite's dependency on 'zip' using custom Setup.lhs (#21,#22).

zip-archive 0.2.3.6

  • Removed hard-coded path to zip in test suite (#21).
  • Removed misplaced build-depends in cabal file.

zip-archive 0.2.3.5

  • Allow compilation with binary >= 0.5. Note that toArchiveOrFail is not safe when compiled against binary < 0.7; it will never return a Left value, and will raise an error if parsing fails, just like toArchive. This is documented in the haddocks. This is ugly, but justified by the need to have a version of zip-archive that compiles against older versions of binary.

zip-archive 0.2.3.4

  • Make sure all path comparisons compare normalized paths. So, findEntryByPath "foo" will find something stored as "./foo" in the zip container.

zip-archive 0.2.3.3

  • Better normalization of file paths: "./foo/bar" and "foo/./bar" are now treated the same, for example. Note that we do not yet treat "foo/../bar" and "bar" as the same.

zip-archive 0.2.3.2

  • Removed lower bound on directory (>= 1.2), which caused build failures with GHC 7.4 and 7.6.
  • Added travis script for automatic testing on 3 GHC versions.

zip-archive 0.2.3.1

  • Require binary >= 0.7 and directory >= 1.2. The newer binary is needed to provide toArchiveOrFail. The other change is mainly for convenience, to avoid lots of ugly conditional compilation.

zip-archive 0.2.3

  • Export new function toArchiveOrFail. Closes #17.
  • Set general purpose bit flag to use UTF8 in local file header. Otherwise we get a mismatch between the flag in the central directory and the flag in the local file header, which causes some programs not to be able to extract the files. Closes #19.

zip-archive 0.2.2.1

  • Fix a stack overflow in getWordsTillSig (Tristan Ravitch).

zip-archive 0.2.2

  • Set bit 11 in the file header to ensure other programs recognize UTF-8 encoded file names (Tobias Brandt).

zip-archive 0.2.1

  • Added OptLocation, to specify the path to which a file is to be added when readEntry is used (Stephen McIntosh).
