Hi all,
Commit c914063fd0eb8c02d8362b86a61933c656a938bc is available for testing, with a view toward releasing 274.
The draft release notes are below. They are getting a little long; it's probably time to call this 274.
Features
- Configure/Build:
- 'make clean-c" now cleans the C object files without removing .tlo files.
- complementary to "make clean-tlo".
- experimental, not tested support for configuring 64 bit time_t on
32 bit Glibc.
- CPPFLAGS (C preprocessor flags) variable noticed and used now.
- TXR now supports building with -fsanitize=undefined option.
- you must specify it yourself via platform-flags, etc.
- configure detects it and puts #define HAVE_UBSAN 1 into config.h
- FFI:
- new feature: enumed bitfield type combination now works.
- Doc:
- numerous documentation fixes.
- Lib:
- cptr-int: allow full unsigned range, so pointers can be specified
as unsigned integers, or using negative signed values also.
- New copy-cptr function; copy copies cptr objects.
- New nandf and norf functions.
- New function random-sample for one-pass reservoir sampling of a sequence.
- load: supports catenated .tlo files now
- cat-files: new function for catenating files, like POSIX cat.
- Getopts:
- various improvements.
- opt-help function/method split up into several.
- Macros:
- New etypecase macro.
- New nand and nor macros and functions.
- Compiler:
- new optimizations.
- TXR Pattern Language:
- new function match-fboundp for testing whether a symbol has a binding
as a pattern function.
- Expander:
- new @,expr hack: quasiquote generates (sys:var ...) or (sys:expr ...)
based on type of substituted value.
- macro-time is no longer a special operator, but a macro.
- Listener:
- Hack: Ctrl-V Ctrl-J now inserts CR (i.e. new line in multiline mode) rather than a LF.
- Good for people used to inserting line breaks in GNU Readline.
- Improvement in method completion.
- getopts:
- Numerous improvements, mainly in area of help generation.
Bugs
- TXR Pattern Language:
- bug fixed in @(freeform)
- involves bugfix in lazy-str-get-trailing-list function.
- filtering now throws when there is an invalid filter,
due to a fix in the filter-string-tree function.
- Parser:
- bug: carriage returns in JSON not tolerated.
- Configure/Build
- fixed broken file offset bits detection, resulting in no large
file support on 32 bit Glibc platforms (regression since 244).
- fixed broken syntax in unwind.h causing build to break if
CONFIG_DEBUG_SUPORT disabled.
- Macros:
- sum-each, mul-each: handle no vars case.
- typecase: return nil from formless clauses.
- fix broken :key parameters.
- Lib:
- carray: allow t and floating 0 in sub and replace.
- carray-replace: two overrun bugs.
- separate: wrong return value when seq is nil.
- time structure: added missing wday and yday slots.
- Listener:
- bug handling comments in plain mode.
- issue handling Ctrl-C in plain mode.
- Structural Pattern Matching:
- quasiliteral match wrongly allowing loose prefix matching.
- `@{nil #/regex/}` wrongly throwing exception.
- Command Line:
- -Dvar now binds var to empty string rather than t.
- this t was some thing inadvertently introduced in 2014.
- -Dvar=foo=bar (value containing equal sign) works.
- -Dx,y,z now diagnosed.
- Vim Syntax Files:
- improvement in handling multi-line string literals.
- Search trees:
- fixed two array underruns found by ubsan.
- both situations work reliably by fluke in unfixed code due the memory
cell below the array reliably being zero bits.
- PRNG:
- undefined behavior (32 bit shift of 32 bit value) in random function.
- Autoload:
- General:
- numerous numeric conversion issues identified by ubsan were
addressed in various places in the code base.
- Missing autoload for *in-compilation-unit* caused loading problem for
compiled code making use of with-compilation-unit.
