Dear SWI-Prolog user,
I’m happy to announce the stable version 8.0.2. This version fixes a
number of important issues:
- Windows installer failing to install menu and desktop shortcuts
- MacOS binary failing to run X11 (xpce, developmen tools)
- JPL (Java interface) crash when using threads
- Fix large performance degradation in exception recovery.
- Fix possibly huge memory usage for programs using retract(all)
intensively on predicates that are rarely inactive. - Fixed memory leak in trie_gen/3 (tabling)
- Fix possible buffer overrun handling buffer memory > 2Gb
See below for details and various other additions and minor fixes.
Enjoy --- Jan
SWI-Prolog Changelog since version 8.0.1
-
FIXED: convert ‘annotated’ stack_limit command line option
to an integer when qcompiling a toplevel Backport for
ab243f50cd7c6ee42ad4cef85d81d11f21f2a8a3 -
ENHANCED: Windows: Updated swipl.ico for higher resolutions, so we
no longer have to simplify it. -
INSTALL: Windows: properly install shortcuts.
-
FIXED: trie_gen/3: memory leak
-
ENHANCED: Use a buffer rather than a linked list for trie enumeration
choice points. Reduces memory and provides a small speedup. -
ENHANCED: Avoid GET_LD for internal _PL_unify_atomic()
-
SECURITY: possible buffer overrun when dealing with very large strings
-
BUILD: Update CMAKE.md and enhanced cmake/CheckEnv.cmake, checking
the environment for things that may break the build. -
ENHANCED: allow plain integer values to be passed to --stack_limit
command line option -
ENHANCED: Avoid trapping debug hooks for setup_call_cleanup/3 and
friends. This avoids about doubling the overhead when the development
environment is used (PceEmacs and/or SWISH). -
ADDED: Sandbox declarations for nb_linkval/2 and
nth_integer_root_and_remainder/4 -
PORT: Remove
-s BINARYEN_METHOD='native-wasm'
as this is no longer supported. See
https://www.google.com/url?q=https%3A%2F%2Fkripken.github.io%2Femscripten-site%2Fdocs%2Fcompiling%2FWebAssembly.html%23debugging&sa=D&sntz=1&usg=AFQjCNHxLe2QvzskaC58CouZdjzaqCW9Dw -
PORT: Make sure to include CMAKE_CROSSCOMPILING_EMULATOR when setting
the PROG_SWIPL -
PORT: Make alignment detection work for Emscripten.
-
FIXED: library(prolog_colour): Avoid an exception on :- meta_predicate
p(). -
FIXED: pack_remove/1 if the pack exists but was not attached due to
a lacking foreign library. If the pack is really missing it now just
prints a message instead of raising an exception. Paulo Moura. -
PORT: Avoid dependency on C99 for alignment check.
-
FIXED: PL_thread_attach_engine(NULL) crashed. Stisko.
-
FIXED: Declare dynamic/1, multifile/1 and discontiguous/1 as
iso.
This avoids accidental redefinition. -
BUILD: Allow scripts/pgo-compile.sh to run from any build dir, also
if this is not an immediate subdir of the source. Paulo Moura. -
PORT: Allow building in Haiku
-
PORT: Force compiling and linking against XQuartz on MacOS when
creating a bundle. -
ENHANCED: delete lingering clause indexes older than the oldest active
predicate access -
ENHANCED: Do not request a garbage collection after an exception
unless we ran out of stack on a stack that is subject to GC. -
ENHANCED: No longer perform forced GC before calling the user exception
hook. GC is allowed inside the hook, so there is no reason to do so. -
MODIFIED: No longer use print_message/2 for
trace_gc. If GC happens
in some parts inside the VM we cannot handle calls to Prolog safely. -
FIXED: Make sure closing a zipper twice does not open the stream twice.
-
TEST: Avoid name clash in tabling tests.
-
ENHANCED: Verify a predicate has no clauses when :- table is declared.
-
FIXED: Issue#82: Throw a floating point exception when NaN/Inf floats
need to be converted to an integer. -
FIXED: Moved setting the SIGINT handler from resetTracer() to
initTracer() so it won’t reinstall the default SIGINT handler on
abort if the user changed the binding. -
FIXED: on_signal/3 handling of
throw. Peter Ludemann. -
FIXED: qsave_program/2: deal with
prologanddefault
toplevels. Keri Harris.
Package archive
- ADDED: archive_foldl/4
Package clib
- DOC: Fixed a small typo in chmod/2 documentation.
Package http
- DOC: Use new
[[library(http/json)]]notation to get proper
paths for the source files included byjson.md. Also updated the
documentation intro for JSON a bit.
Package jpl
- FIXED: Install
env.shinto the Java examples and update it to deal
with both the installed version and version from the build environment.
Package pengines
- FIXED: in pengines:output_result for CORS and write_result hook
-
Currently CORS support is only implemented for the
json
format. It really should be applied to all output when thehttp:cors
setting is enabled (including any error responses generated by
the http server libraries). The same philosophy should apply to
disable_client_cache/0. -
The
write_result/3hook is not called when the format type is
prologdue to clause ordering ofoutput_result/3. The clause that
calls the hook should be first (analogous to theevent_to_jsonhook in
event_term_to_json_data/3). A benefit is that attributed variables
can by returned in response data via the hook.
-
Package pldoc
-
ADDED: Allow for [[Alias(Segments)]] to reference to files in markdown.
-
FIXED: Documentation search should find perfect matches on
identifiers. Nicos Angelopoulos. -
FIXED: Avoid duplicating documentation for PlDoc comment blocks that
document multiple predicates.
Package sgml
-
ADDED: xpath/3: text(string) to get the DOM text as a string rather
than an atom. -
FIXED: xpath/3: make extraction work if the document was parsed
using cdata(string).
Package swipl-win
-
DEBUG: Add debug messages to find the preferences path and track the
font dialog. -
FIXED: Issue#83: Qt console menu handling. This issue was due to
omitted resources in the cmake build. Note that this does not fix
the X11 problems of the MacOS bundle reported in the same issue.
