Hi all,
Commit d1caae1ac6f393d0bc8cbcf62804dbac0033d133 is available for testing, with a view toward releasing 273.
Draft release notes:
Features
- compiler:
- new jump optimizations.
- register compacting optimization: greatly reduces stack use,
especially of complex functions, and improves cache locality.
- lib:
- new functions: tuples*, rot, nrot, subq, subq, subqual, subst, pairlis.
- hash tables:
- use 64 bit hash on 64 bit platforms, rather than 32 bit.
- search trees:
- new function tree-count, and length/len works on trees.
- duplicate keys supported:
- tree, tree-insert, tree-insert-node have optional argument for
allowing duplicates.
- tree-delete-specific-node allows specific node to be
removed, when removing by key is ambiguous.
- priority queue support:
- tree-min, tree-min-node, tree-del-min, tree-del-min-node
- oop/structs:
- new feature: application-defined struct clause macros.
- new: :delegate and :mass-delegate clause macros for
generating delegate method boilerplate with minimal code.
Bugs
- compiler:
- fix non-working (compile '(lambda ...)).
- buffers:
- file-get-buf and command-get-buf use unbuffered I/O
to read the exact number of bytes into the buffer,
avoiding reading more bytes than requested.
- case macros (mainly affecting casequal):
- fixed 2017 regression causing a key value like ((a b c)),
which is the single key (a b c), to be wrongly converted
into a list of three keys.
- each-match, each-prod, sum-each family of macros:
- documented and added missing anonymous block
- maprodo: spurious non-nil return value issue.
- interpreter: bug in interpreting optional parameters,
present in original implementation from 2014 (absent in compiler).
- iteration: gc stability problem in iter-begin and iter-reset.
- define-accessor: broken argument handling.
- less/greater: gaping bug, vectors not supported.
