Changelog for fs-api-0.4.0.0

Revision history for fs-api

Make the orphan Condense instance for System.IO.SeekMode into a non-orphan instance. The instance is still exported from the same modules it was exported from previously, System.FS.API.Types in particular.

Make it build with ghc-9.12.
Support io-classes-1.8.0.1.
Drop support for ghc-8.10.
Bugfix: opening a file in read mode now expects the file to exist already. This was already the semantics when using hOpen from the ioHasFS instance, but it was not reflected in the allowExisting function. allowExisting Readmode now returns MustExist instead of AllowExisting.
Bugfix: hGetBufExactly and hGetBufExactlyAt would previously try to read too many bytes in the presence of partial reads. These functions now properly count the number of remaining bytes that have to be read.

Support io-classes-1.6 and io-classes-1.7. Older versions of io-classes are no longer supported.

Remove orphan Show instance for Foreign.C.Error.Errno.
Provide implementations for the new primitives in the IO implementation of HasFS. As a result, ioHasFS now requires that PrimState IO ~ PrimState m.
Rename Util.CallStack and Util.Condense to System.FS.CallStack and System.FS.Condense respectively.
Make modules in the System.FS.IO.Internal hierarchy public, inspired by "Internal convention is a mistake". The following modules are moved/renamed:
- System.FS.IO.Internal is moved to System.FS.IO.Unix on Linux and MacOS systems, and moved to System.FS.IO.Windows on Windows systems.
- System.FS.IO.Internal.Handle is moved to System.FS.IO.Handle.

Add new primitives to the HasFS interface for performing file I/O with user-supplied buffers: hGetBufSome, hGetBufSomeAt, hPutBufSome, and hPutBufSomeAt.
Add compound functions, built from the new primitives in HasFS: hGetBufExactly, hGetBufExactlyAt, hPutBufExactly, and hPutBufExactlyAt.
NFData instances for FsPath, HasFS and Handle.
Add FsPath combinators: (<.>) and addExtension, (</>) and combine.

Add a clarification in the documentation of FsPath that the user is responsible for picking sensible directory/file names.
Bump upper version bounds for io-classes to 1.6
Make it build with ghc-9.10.
New primitive ^>=0.9 dependency
Tight dependency bounds.

Modules that are required for ioHasFS should never be used by client code. For this reason, we move the relevant modules into an Internal hierarchy.
- Move the System.IO.FS module to System.FS.IO.Internal.
- Move the System.FS.Handle module to System.FS.IO.Internal.Handle.
Move strict and lazy compound definitions for reading/writing bytes into separate modules System.FS.API.Strict and System.FS.API.Lazy. Both modules re-export System.FS.API.

Update the code to compile with io-sim-1.0.0.1.
