Changes since 16.0.0
* API changes
- si:do-setf accepts optional parameter stores. New lambda-list:
(access-fn function &optional (stores `(,(gensym))))
This change is backward compatible.
- New MP functions:
mp:with-rwlock
mp:try-get-semaphore (non-blocking)
mp:mailbox-try-read (non-blocking)
mp:mailbox-try-send (non-blocking)
- Added back removed C interfaces
ecl_import_current_thread
ecl_release_current_thread
- When cl-truename encounters a broken symlink, it returns its path
instead of signalling a file-error
- Deprecated variables has been removed
c::*suppress-compiler-warnings*, c::*suppress-compiler-notes*
- Random state might be initialized by a random seed (truncated to
32bit value) or by a precomputed array.
Latter is designed to allow reading back the printed random state
(when printed readably), not as an array to initialize the random
state.
- C99 supporting compiler is mandatory for C backend.
- COMPILER::*cc_is_cxx*: New variable to switch the output extension of
emitted compiler code to ".cxx" when configured with "--with-c++". This
eliminates compiler warnings that compiling C++ with a ".c" extension is
deprecated; this is seen mostly with Clang++.
- Added Clang-specific pragmas to disable return type, unused value and
excessive parentheses warnings, which are fairly harmless, but annoying
and clutter user output.
- GRAY:CLOSE isn't specialized on T to preserve compatibility with some
libraries.
* Enhancements:
- Added code walker (present as *feature* :walker)
- Testing framework cleanup
- Format fallbacks to prin1 if infinity or NaN are passed to it
- Annotations are added at runtime (better integration with SLIME)
- Mersenne-Twister RNG has new 64 bit implementation for appropriate
machines
- Add sockets implementation for android platform
- Add android build target (official android support)
* Issues fixed:
- si:open-unix-socket-stream accepts both string and base-string
(automatic coercion is performed)
- Long form of DEFSETF accepts multiple-values as a store forms:
(defsetf gah (x) (y z) `(list ,x ,y ,z))
(setf (gah 3) (values 3 4))
- Building with single-threaded boehm works if ECL threads are disabled
- Using labels works with sharp-S-reader
(read-from-string
"(#1=\"Hello\" #S(sharp-s-reader.1.example-struct :A #1#))")
- Generated C code works well with IEEE 754 infinities
(regression tests created)
- User-defined heap sizes can now exceed the size of a fixnum on 32-bit
- The heap size limit was intended to be 1GB on 32-bit or 4GB on 64-bit
but inconsistency between ECL_FIXNUM_BITS and FIXNUM_BITS in the code
prevented the heap to grow for 64-bit. This now occurs, and a few
other less visible bugs were fixed by restoring consistency to
ECL_FIXNUM_BITS.
- EXT:EXTERNAL-PROCESS-WAIT potential race condition fix
- Building with object files not created by ECL works (CFFI wrappers)
- Regression regarding initialization of build by ECL libraries from
external code fixed. Static and shared libraries initialization
funcitons has predetermined name while object files has randomized
names.
- Random state initial state generation was buggy and insecure (entropy
from urandom was rejected)
- Fix `listen' on streams when FILE_CNT isn't available (use read instad
of fread)
- `FIND' compiled with C compiler didn't respect `START' nor `END'
arguments. Compiler macro is fixed now and should work as expected
- `compute-applicable-methods-using-classes` bugfix
