- Update from version 2.3.2 to 2.3.3 - Update of rootfile - Changelog 2.3.3 1. src/slposdir.c: stat_file now support open file descriptors, in addition to filenames. 2. src/sltoken.c: Ignore the \r character in multiline strings that appear to have CRLF line terminators. (Manfred Hanke) 3. *.tm: minor documentation updates 4. src/slang.h: SLANG_VERSION_STRING was missing the "pre" prefix. 5. src/sltermin.c: Added support for TERMINFO_DIRS (based upon a patch forwarded by Jörg Thalheim) 6. src/slarray.c: src/slarray.c: some integer overflow checks were resulting undefined behavior (reported by Sergey) 7. modules/csv.sl: Strip leading/trailing whitespace from column names 8. src/slsmg.c,sldisply.c: Removed static buffers with sizes dependent upon SLTT_MAX_SCREEN_ROWS/COLS in favor of dynamically allocated ones. 9. modules/chksum-module: added CRC-8,16,32 checksums to the chksum module 10. modules/csv.sl: An error message in the form of a dollar-string was not marked as such. 11. modules/csv.sl: Added support for empty CSV files 12. src/sltime.c: The timegm function will ignore the tm_wday and tm_yday fields, and instead use the tm_mon and tm_mday fields. 13. modules/mkfiles/makefile.all: Added a target for chksum_crc.o for win32/64 platforms (see change #9) 14. modules/chksum-module.c: The memset function was used with the wrong structure size causing a buffer overflow on 32 bit systems. 15. src/terminfo/parsecaps.sl: Tweaked an auto-generated comment produced by parsecaps.sl to produce a more deterministic build (Ian Rogers). 16. src/slarray.c: Changed two instances of index errors to throw an IndexError exception instead of InvalidParmError exception. 17. src/slposdir.c; The statvfs function was returning a struct with duplicated f_bsize fields. 18. *.c: In switch statements, changed the /* drop */ comment to /* fall through */ to avoid gcc-8 warnings. 19. modules/csv.sl: If a comment string appears at the start of a line forming a multiline string, then treat it as part of the string. 20. slsh/lib/timestamp.sl: Added a function timestamp_parse that parses strings such as `Thu May 14 18:05:05 2020` and returns the number of seconds since the Unix epoch. 21. src/slregexp.c: Added \D (non-digit), \s (whitespace), and \S (non-whitespace). 22. src/slstrops.c: Added a compiled regexp cache 23. src/slstdio.c: Added trim qualifier to the fgetlines intrinsic: ;trim=1 ==> trim trailing whitespace ;trim=2 ==> trim leading whitespace ;trim=3 ==> trim leading and trailing whitespace 24. slsh/lib/timestamp.sl: When matching a regexp to a timestamp, start with the RE that was used in the previous match. 25. Another timestamp RE tweak to pickup additional irregular forms 26. modules/csv.sl: If a CSV file has a byte-order mark (BOM), ignore it. 27. src/sldisply.c: Increased the buffer size for the SLtt_tgoto function to allow for larger terminfo strings 28. modules/Makefile.in: Added STATS_OBJS to the clean target 29. src/slstrops.c: The is_substr function was not handling a NULL argument 30. slsh/lib/timestamp.sl: Corrected a regular expression for a timestamp with "Z" as the timezone. 31. modules/csv-module.c: Fields with an embedded \r were not being properly handled. 32. src/slarray.c: Improved the speed of multi-dimensional array indexing by about a factor of 2 33. slsh/lib/timestamp.sl: The computation of leap days was incorrect for some years 34. src/slang.h: Added `typedef void (*SLFVOID_STAR)(void)', which will replace FVOID_STAR in version 3. The library code was updated to use this. 35. slsh/lib/fswalk.sl: Added an optional callback argument to the fswalk that is called when leaving a directory. 36. modules/termios-module.c: Avoid a potential problem with the tcgetpgrp intrinsic in the unlikely case that sizeof(pid_t) is larger than sizeof(int). 37. src/slarray.c: Simplified the range checking in the linear_get_data_addr function and removed unused code. 38. Updated the copyright year 39. slsh/lib/fswalk.sl: Change #35 regression: The get_stat function was being called with the wrong number of arguments. 40. src/slarith.c: Additional binary arithmetic optimizations involving arrays of char and short. 41. src/slang.c,slarray.c: Added qualifier support to the array_map function. 42. src/slang.c: Flagged the use of an uninitialized variable as soon as it is accessed ("pushed") rather than waiting until it is used ("popped"). Fixed a bug in slsh/lib/setfuns.sl:union that was detected by this change. 43. src/sl-feat.h: Floating point support by the interpreter is now required. The library has not compiled without it for a long time. As such, this option is no longer available. 44. */test/*.sl: Surrounded regression test code that makes use of complex numbers with `#ifexists Complex_Type' so that they run when the interpreter is compiled without complex variable support. 45. src/slarray.c: The _pSLarray1d_push_elem needed to be exposed when compiling the interpreter without optimization. 46. src/slarith.c,...: Rewrote the various macros used by this file to simplify the code, permit better optimization, and easier maintenance. Some of the loops were also unrolled. 47. src/slarray.c: Made the array bounds index checking code more uniform for better readability. 48. src/slarray.c: The previous change introduced a bug that caused array indexing with no (empty) indices to fail. 49. modules/chksum-module.c: When a CRC object went out of scope without being closed, it would leave its value on the stack. 50. slsh/lib/process.sl: If the file descriptor that is used to communicate messages from the child process back to the parent is requested by the caller, then dup an unused one. To facilitate testing, two additional hooks were added: exit_hook and exec_hook. 51. slsh/lib/cmdopt.sl: If a command line option is associated with a callback function, and the value of the command line argument is optional, pass the default value to the callback if not given on the command line. 52. modules: Added cumulant function to the stats module; updated regression scripts/unit tests for better code coverage; fixed a bug in the _zlib_inflate_reset function where deflateReset was being called instead of inflateReset. 53. slsh/lib: Updated unit/regression tests for better coverage 54. slsh/lib/print.sl: Use >= instead of > when comparing the number of screen rows to determine if the pager should be used. 55. modules/chksum-module: Added sha224, sha256, sha384, and sha512 algorithms kindly provided by Jakob Stierhof 56. modules/chksum-module: Added HMAC message authentication code algorithm (Jakob Stierhof) 57. modules/mkfiles/makefile.all: Added chksum_sha2 to the non-Unix makefile. 58. src/slgetkey.c: Use memmove instead of SLMEMCPY to avoid issues with coping to an overlapping buffer. (William Ahern) 59. modules/pcre.sl: The options qualifier was not being properly handled by the pcre_matches function. 60. src/_slang.h,etc: replaced the dependence of the internal _pSLang_get_run_stack* functions, which return absolute pointers, in favor of relative offsets. 61. src/slang.c: Made the run-time stack dynamically growable up to a maximum configured size. 62. modules/: Documentation updates 63. src/: Added _set_bos/f_compile_hook functions to specify a function to get called when a statement or function gets compiled. 64. src/sllimits.h: Reduced the initial stack size to a value similar to what it was before change #61. 65. src/slarrfun.c: array_swap was returning a copy of the input array when when swapping an array element with itself (bug reported by Jakob Stierhof) 66. modules/csv.sl: If _csv_decode_row fails, include in the error message the line number of the file where the error was detected 67. modules/socket-module.c: Corrected an error message for the bind function 68. Updated the copyright year 69. Added slcov script which generates lcov-compatible code coverage data 70. autoconf/aclocal.m4: Updated to v0.3.4.1 71. slsh/Makefile.in: Changed the order of the linker flags to avoid a linking problem on MacPorts (Ryan Schmidt) 72. slsh/lib/cmdopt.sl: Corrected a usage message 73. src/slposio.c: Added the flock function for the creation of advisory locks 74. src/slcurses.h: Added 'extern "C"' to enable the file to be used in C++ programs; also marked some variables as dynamically exportable by using SL_EXTERN (Gisle Vanem) 75. src/slstrops.c: "%0*" was being flagged as invalid by the sprintf function (Jakob Stierhof) 76. modules/csv.sl: When writing a CSV file with a single row, convert any scalar data values to single element arrays. 77. src/Makefile.in, slsh/Makefile.in: Addressed some dependency problems found by `make --shuffle` that were causing parallel builds to fail (Sergei Trofimovich) 78. src/slarray.c: Flag out-of-range indexing of indefinite ranges involving negative indexes, e.g., x = [1]; y = x[[-2:]]; Previousely this resulted in y = [1,1] instead of an error. 79. modules/csv.sl: Avoid indexing an empty array with a negative index (detected by change #78) 80. src/slarray:c: #78 was flagging x[[:-2]] as invalid instead of producing an empty array for x=[1] 81. src/slarray.c: Tweaked the handling of negative indices in indefinite ranges such that x[[:-i]] will produce an empty array wheneve i > length(x) 82. src/sltermin.c: Added support for so-called user-defined terminfo extensions. In particular, if the terminfo file defines RGB=true, then truecolor support will be enabled. 83. src/sldisply.c: The Has_True_Color variable was not defined for 32 bit systems 84. modules/csv.sl: Improved read speed for large CSV files 85. src/test/posixio.sl: Do not test the flock function using an NFS mounted direcory, which requires lockd to be running on the server Signed-off-by: Adolf Belka <adolf.belka@ipfire.org>
