package tar-mirage

v3.3.0 (2025-03-06)

• Deprecate Tar.( let* ) in favor of the new Tar.Syntax module (@kit-ty-kate, #167)
• tar-mirage: remove mirage-clock dependency in favor of mirage-ptime (@hannesm, #168)

v3.2.0 (2025-01-20)

• Fix the Tar monad with Tar_gz and allow the read operation (@dinosaure, @BChabanne, @reynir, #161)
• Add x-maintenance-intent field into opam files (@hannesm, #162)
• Defaults level per entries to the global level (@reynir, #157)
• Update Tar_eio with the last version of tar (@patricoferris, #159)

v3.1.2 (2024-09-20)

• Fix a wrong assumption in Tar_lwt_unix.run for Tar.Really_read _ that one tar block was always read. This meant that using Tar.Really_read with a size different from 512 would fail. (Reported by @jonahbeckford, review by @hannesm, @reynir, #153)
• Document better the actual behavior of Tar_unix.extract and Tar_lwt_unix.extract (@reynir, #155)

v3.1.1 (2024-09-13)

• Expose Tar_lwt_unix.run as we do with Tar_unix.run and Tar_eio.run. This was an oversight in v3.0.0. (Reported by @jonahbeckford, @reynir, #150)

v3.0.0 (2024-08-05)

• Fix Header.marshal and the checksum and the length (@reynir, #145)
• Delete a mutable field about the level into the header (@hannesm, #141)

• BREAKING: de-functorize the package (@hannesm, @reynir, @dinosaure, #140, #143, #146)

  These PRs attempt to de-functorize Tar so that users can implement I/O themselves, using Tar's own element serialization/deserialization functions to take advantage of read/write methods. This avoids imposing on the user the implementation of a module that is too rigid in his/her case (which could have performance implications).

  Tar offers functions for serializing/deserializing tar-specific elements from string. It is then up to the user to know how to obtain or write these strings.

  To this, these PRs add "logics" (see 'a Tar.t) requiring read and/or write implementations and describing how to extract all entries from a tar file or how to write a tar file according to a "dispenser" (like Seq.to_dispenser) of entries.

  These logics do not depend on a particular "scheduler", and these PRs propose a derivation of these logics with tar-unix, tar-eio and tar-mirage. These latter derivations mean that the API for these packages has only been extended, and there are no breaking changes as such.

  These logics also make it easy to offer a compression/decompression layer with decompress, so you can easily manipulate and/or create a .tar.gz file.

v2.6.0 (2023-09-07)

• Add eio backend for tar in tar-eio (@patricoferris, review by @talex5, @reynir, #132)
• Also apply backwards compatibility fix when GNU LongName is used. The compatibility fix is unfortunately also applied for unknown-to-ocaml-tar link indicators (reported by @gravicappa in #129, @reynir, #133)
• tar: support pax Global Extended Headers. This adds state to tar parsing. (#119, #120, @MisterDA)
• Support GNU LongLink and LongName. Prior, Tar.HeaderWriter and Tar.HeaderReader supported both, but Tar.Header.Link only had LongLink and (de)serialized to (from) GNU LongName (#127)
• Compatibility level when reading / parsing is removed. Only GNU LongLink/LongName extensions were affected by the compatibility level when reading (#127)
• Add module types Tar.HEADERREADER and Tar.HEADERWRITER describing the output of Tar.HeaderReader and Tar.HeaderWriter respectively (#127)
• Types Tar.READER.t and Tar.WRITER.t are renamed to io (#127)
• Add write_global function for writing a global PAX extended header (#127)
• Rework IO-specific modules (tar-unix etc.) harmonizing them (#127)
• Avoid exceptions in tar and use result instead. The exceptions End_of_stream and Checksum_mismatch are removed (#127)
• Remove the Tar_cstruct module as it was unused (#127)
• Remove debug printers (#127)
• Finally remove the unused camlp-streams dependency (#127)

v2.5.1 (2023-06-20)

• Treat headers with link indicator '0' or '\000' (Normal) as directories for backward compatibility (reported in #129, fix by @reynir)

• File names and link names are used from PAX headers when parsing (reported by @gravicappa, fixed in #128 by @reynir)

v2.4.0 (2023-03-30)

• Switch to alcotest for tests (@MisterDA, review by @reynir, #121)
• BREAKING: fix ustar magic version. Previously, the version "0\000" was serialized instead of the correct version "00". This means tar archives may not be reproducable with older versions. (@reynir, @hannesm, #117 and #122)
• Remove ppx_cstructdependency (@hannesm, review by @reynir, #117)
• Properly skip Pax GlobalExtendedHeaders (@MisterDA, @reynir, #116 and #118)

• Update usage of cstruct in tar: unnecessary memsets removed, use Cstruct.of_string (@hannesm, #93)
• Fix tar-mirage read buffer allocation error (@reynir, review by @hannesm, #94)
