See the end for copying conditions. Please send Guile bug reports to bug-guile@gnu.org. +Changes in 2.2.5 (since 2.2.4): + +[XXX TODO: Add more details to selected items below] + +* Notable changes + +** Greatly improved performance of bidirectional pipes. + +The performance of bidirectional pipes, as created using 'open-pipe' or +'open-pipe*' with OPEN_BOTH mode, has been improved by roughly 3 orders +of magnitude. + +** New 'get-bytevector-some!' I/O primitive. + +** get-bytevector-{some,some!,n!} support suspendable I/O. + +* Compiler improvements + +** compile: Add -Wshadowed-toplevel. +** compile: Add '-x' flag. + +* Miscellaneous improvements + +** Bootstrap optimization + +eval.go and psyntax-pp.go are now built before the rest of the .go files +so that they are processed by a fast macro expander. This saves time +when using parallel builds. + +** put-u8: Always write a single byte, regardless of the port encoding. +** Optimize fixnum exact integer square roots. +** scm_mkstrport: Optimize the POS -> BYTE_POS conversion. +** stexi->shtml: Add support for @i, @math, @tie and @dots. +** SRFI-19: Support ~N in string->date. +** SRFI-19: Update the leap second table. + +** Define AT_SYMLINK_NOFOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH. + +AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH are now available +from Scheme, if supported on the platform. + +** time: Support expressions that return any number of values. +** time: Use 'syntax-rules' instead of 'define-macro'. +** Clarify the documentation for 'nil?'. +** Clarify the manual's "Processes" section. +** Avoid 'with-latin1-locale' in binary I/O tests. +** Update user-visible copyright years. + +* Bug fixes + +** Avoid regexp ranges in HTTP inter-protocol exploitation check. + +** Fixes to the SRFI-19 time/date library. + +*** Fix TAI->UTC conversions, leap second handling, etc. +*** Fix handling of negative years and negative julian days. +*** Fix normalization of seconds and nanoseconds in time records. +*** time-utc->date: Support non-integer nanoseconds values. +*** Check for incompatible types in time comparisons. + +** Improve overflow checks in bytevector, string, and I/O operations. +** Fix type inferencing for 'nil?' and 'null?' predicates. +** Fix 'atomic-box-compare-and-swap!'. +** Make URI handling locale independent. +** Strings, i18n: Limit the use of alloca to approximately 8 kilobytes. +** Avoid passing NULL to 'memcpy' and 'memcmp'. +** scm_to_stringn: Avoid passing NULL to c_strcasecmp. +** Save and restore errno in the signal handler. +** r6rs-ports: Accept 'port-position' values greater than 2^32. +** r6rs-ports: 'put-bytevector' accepts 64-bit integers. +** Fix documentation of R6RS 'binary-port?' to reflect reality. +** Fix R6RS call-with-{input,output}-file to open textual ports. +** Update (ice-9 match) to include selected bug fixes from upstream. +** open-process: Fix dup(2) and execvp(2) error handling. +** bytevectors: Support large indices in integer accessors. +** bytevectors: Fix list validation of *list->bytevector procedures. +** Gracefully handle huge shift counts in 'ash' and 'round-ash'. +** In 'ash' and 'round-ash', handle right shift count of LONG_MIN. +** Use 'scm_from_utf8_{string,symbol,keyword}' for C string literals. +** web: Add support for HTTP header continuation lines. +** scm_seed_to_random_state: Support wide string arguments. +** Do not warn the user when 'madvise' returns ENOSYS. +** Add 'texinfo' as a dependency in the README. +** Don't mutate read-only string in ports test. +** Remove redefinition of when & unless in snarf-check-and-output-texi. +** Fix strftime when Guile is built without threading support. +** Avoid leaking a file descriptor in test-unwind. +** Fix binary output on files created by mkstemp!. +** Fix crypt-on-glibc test error. +** Fix race when expanding syntax-parameterize and define-syntax-parameter. +** Add a fallback value for the locale-monetary-decimal-point. +** Handle newlib C library's langinfo constant names. +** Make locale monetary conversion tests be less strict on terminal whitespace. +** Disable test for current value of setitimer on Cygwin. +** Fix gc.test "after-gc-hook gets called" failures. +** Update iconv.m4 from gnulib, to fix iconv leak during configure. +** guild compile: Add missing newline in "unrecognized option" error message. +** 'basename' now correctly handles "/" and "//". +** Make srfi-71 visible through 'cond-expand'. + + + Changes in 2.2.4 (since 2.2.3): * New interfaces and functionality |
