Pietro Cerutti	a51d36440c	lang/seed7: update to 05_20210106 ... Changelog: - The declaration of in-parameters has been changed to work the same way as all other parameter declarations (val-, ref-, inout-, attr- and in-var-parameters). Many thanks go to Zachary Menzies for pointing out a problem with in-parameters and for providing a test program. The new in-parameters fix this problem. - The support for function types (func aType and proc) in interpreter and compiler has been improved. - The support for Emscripten (a C compiler that generates JavaScript and WebAssembly) has been improved. The support of Emscripten is experimental (see also src/read_me.txt). - The library http_response.s7i has been improved to set the correct content-type for more file types (css, javascript, wasm, gif, bmp, pdf). This way the comanche webserver also works better. - The function getCgiParameters() in cgi.s7i has been improved to accept also elements wihout equals sign (in this case value is assumed to be ""). - The function readPropertyFile8() has been added to the library propertyfile.s7i. This function processes an UTF-8 encoded property file. - In propertyfile.s7i the function readPropertyNameOrValue() has been changed to work correct for unicode escapes (\u) and for escaped newlines. An extended unicode escape (\U) has been added also. - Testcases that check if seek() does clear the EOF flag have been added to chkfil.sd7. - The Seed7 parser (used by interpreter and compiler) has been improved, to recognize if the same syntax is declared twice. In this case a compile-time error is written. - The FAQ has been improved to explain the simple profiling of the Seed7 compiler. - The simple profiling of the compiler has been improved to recognize, if a function has been left without taking profiling into account. - The compiler has been improved to recognize if a raise statement leaves a function and generates code to make the profiling work correct (if it has been enabled). - The recognition of constant expressions in the compiler has been improved to consider variable functions as variable. The changes are in comp/const.s7i in two functions named isConstantCall(). - Changes have been done in seed7_05.s7i and integer.s7i such that the new in-parameters work as expected. - The interpreter has been improved to support the actions DCL_IN1, DCL_IN2, TYP_SET_IN_PARAM_REF and TYP_SET_IN_PARAM_VALUE. - The functions dcl_in1() and dcl_in2() have been added to dcllib.c. - The functions typ_set_in_param_ref() and typ_set_in_param_value() have been added to typlib.c. - Changes in syntax.c and token.c make sure that the new error SYNTAX_DECLARED_TWICE is recognized. - In prclib.c the function prc_cpy() has been improved to take into account that MATCHOBJECT is constant (and the underlaying object is variable). - In cmd_unx.c the function setenv7() has been improved to work correct, if a value is enlarged. - In cmd_unx.c the functions getenv7(), setenv7() and unsetenv7() have been improved to optionally work case insensitive. - Changes in cmd_drv.h, cmd_rtl.c and fil_unx.c allow that some operating system properties are determined at run-time. This is used for Emscripten. - The functions setenvForNodeJs() and unsetenvForNodeJs() have been added to cmd_unx.c. Now setenv() and unsetenv() have also an effect on the environment used by Node. - The file drw_emc.c has been added. This file provides graphic access using browser capabilities. It is used if Seed7 is compiled with emcc. - The file pre_js.js has been added. This JavaScript code is included by Emscripten. It sets up program path and arguments, if the program runs in the browser. - In cmd_rtl.c the function systemForNodeJs() has been improved to return -1, if the command cannot be executed. - The makefiles mk_emccl.mak and mk_emccw.mak have been improved to store the environment variables in seed7/bin/emcc_env.ini. The macro CC_ENVIRONMENT_INI, which defines the path of seed7/bin/emcc_env.ini, is now written to version.h. This way the Seed7 compiler can be used without setting up Emscripten. - Changes have been done in error.c and error.h to introduce the new errors SYNTAX_DECLARED_TWICE and KIND_OF_IN_PARAM_UNDEFINED. The error UNEXPECTED_SYMBOL has been replaced with EXPECTED_SYMBO. - The functions increaseLevelOfCatchedExceptions() and decreaseLevelOfCatchedExceptions() have been added to comp/error.s7i. These functions are used in comp/prc_act.s7i. - In comp/expr.s7i the function declare_type_if_necessary() has been improved to take a existing typeCategory of BLOCKOBJECT into account. - In comp/type.s7i the function getExprResultType() has been improved to check that the category is a CALLOBJECT. - Definitions of LINKER_OPT_SPECIAL_LIB and SPECIAL_LIB have been added to cc_conf.s7i. - The files s7c.sd7, confval.sd7, cmd_rtl.c, mk_emccl.mak and mk_emccw.mak have been improved to use the new configuration values. - The parameter list of the functions cmdSetGroup() and cmdSetOwner() has been changed in comp/cmd_act.s7i, cmd_drv.h, cmd_unx.c and cmd_win.c. Now group and owner are constant strings. - Documentation comments have been added or improved in cc_conf.s7i, cgi.s7i, csv.s7i, propertyfile.s7i and graph.s7i.	2021-01-11 17:04:05 +00:00

Now PRINT statemens allow a colon (:) between strings to describe a line break. Now INPUT statements allow a colon (:) between input prompt and variable list. A dummy implementation of the predefined subprogram SOUND has been defined. - In seed7_05.s7i the definition of ::= for the type void has been changed to use the action ENU_CREATE instead of PRC_NOOP. This avoids a strange interpreter message (loc not dumped) if a void value is written. - Tests in chkint.sd7 have been split into several functions. - Documentation in the FAQ, the manual and s7c.1 has been improved. - Interpreter and compiler have been improved to support the new action FIL_TRUNCATE. - The compiler has been improved (in comp/inline.s7i in the function push_inline_func_param) to add a "const" for a parameter definition. This avoids a compilation error with g++.	2020-06-04 16:11:01 +00:00
Pietro Cerutti	2d20eca127	lang/seed7: update to 05_20200502 ... 20200502: - As suggested by Zachary Menzies a detection of more modifier keys has been added. E.g.: KEY_SHIFT_LOCK and KEY_NUM_LOCK. These modifier keys have a state. The state of KEY_SHIFT_LOCK can be retrieved with buttonPressed(KEYBOARD, KEY_SHIFT_LOCK_ON). - Several new keys and key combinations such as KEY_PRINT, KEY_PAUSE, KEY_ALT_LEFT and KEY_SFT_MENU have been added to keybd.s7i. Existing definitions in keybd.s7i have been refactored. Key names in keydescr.s7i have been updated. - The program gkbd.sd7 has been improved to show the new capabilies of the keybord interface. - The bas7.sd7 (basic interpreter) example program has been improved.

This reduces the runtime of the xz (lzma2) decompression by 0.8% (measured with gcc and valgrind, when decompressing a binary Seed7 package). - The compiler has been improved to optionally suppress the generation of checks for integer division by zero with the option -sd. - The simple function profiling of the Seed7 compiler has been improved to write the place and the name of the Seed7 function and to avoid a C compiler error about "too many initializers". - The compiler has been improved to write a warning if there is a catch statement for an exception although the checks for this exception have been suppressed (with the option -s). - The compiler has been improved to work correct for all corner cases of the string operations [, mult and @:=. - Testcases for the operators [, mult and @:= and for the functions pos() and rpos() have been added to chkstr.sd7. - Testcases for the exception RANGE_ERROR have been added to chkbig.sd7. The function bigInteger() and the operators radix, RADIX and parse are checked now, if they correctly raise RANGE_ERROR. - Testcases for the exception RANGE_ERROR have been added to chkint.sd7. The functions bytes() and integer() and the operators radix, RADIX, sci and parse are checked now, if they correctly raise RANGE_ERROR. - Testcases for the exception NUMERIC_ERROR have been added to chkint.sd7. The operators div, rem, mdiv, mod and ** are checked now, if they correctly raise NUMERIC_ERROR. - A lot of testcases has been added to chkint.sd7 and chkovf.sd7 in the function check_reduced_overflow_checking_for_sums(). - In comp/big_act.s7i the function process_const_big_ipow has been improved to allow that the check for a negative exponent can be optionally omitted. - In chkovf.sd7 the checks for the operators rem and mod have been improved to allow that the operators return the correct result instead of raising OVERFLOW_ERROR. - Index access in comp/str_act.s7i and comp/bst_act.s7i has been improved to work also for the index integer.first (now the index is casted to (unsigned) and afterwards 1 is subtracted). - In comp/intrange.s7i the function getIntRange has been improved to return better ranges for INT_ABS and INT_NEGATE. - The keyboard driver gkb_x11.c has been improved to support new keys and key combinations.

This reduces the runtime of the xz (lzma2) decompression by 2.3% (measured with gcc and valgrind, when decompressing a binary Seed7 package). - The compiler file comp/intrange.s7i has been added. This file defines the function getIntRange(), which computes the range of possible results for several operators (e.g.: div, rem, mdiv, mod, >>) and functions (e.g.: sqrt, length, pos, rand, log). - The compiler has been improved to use the function getIntRange() to omit overflow checks for addition, subtraction, multiplication and left shift of integer values. This reduces the runtime of the xz (lzma2) decompression by 0.4% (measured with gcc and valgrind, when decompressing a binary Seed7 package). - In the compiler the code generation for the operators div, rem, mdiv, mod, * and << has been improved to work without catching the exception OVERFLOW_ERROR. - The compiler has been improved to allow that a range check is suppressed with -sr for the action FLT_BITS2SINGLE (convert integer to single precision float value). - The compiler has been improved to generate code that writes the error message of a DATABASE_ERROR, if the exception is uncatched. - The compiler has been improved to suppress the usage of the C compiler option CC_OPT_TRAP_OVERFLOW (-ftrapv), if the Seed7 compiler option -so (suppress overflow checks) is used. - The makefiles mk_clang.mak, mk_clangw.mak and mk_osxcl.mak have been improved to define CC_OPT_TRAP_OVERFLOW with the value -ftrapv. - The functions check_mod_by_power_of_two_optimization() and check_mod_by_computed_power_of_two_optimization() have been added to chkint.sd7.

Vlasov for pointing out compilation problems with Visual Studio 2019 and for investigating the problems. - Interpreter and compiler have been improved to support DB2 and SQL Server databases. - In the manual the chapter about the database abstraction API has been improved. - The compiler has been improved to optimize the function replace() (action STR_REPL). Special functions (strChRepl() and strChChRepl()) are used, if the searched or the replaced string consist of one character. This works even, if a character is converted to a string with the function str(). - Testcases for replace() have been added to chkstr.sd7. - The program bigfiles.sd7 has been improved to search for the biggest directories additionally to the biggest files. - The libraries keybd.s7i and keydescr.s7i have been improved to support KEY_MOUSE_FWD and KEY_MOUSE_BACK. - The library sql_base.s7i and the programs db7.sd7 and sql7.sd7 have been improved to support DB_DB2 and DB_SQL_SERVER. - In striutl.c the function stri_to_standard_path() has been improved, to do a smarter mapping from a DOS/Windows path to the Seed7 standard path representation. - In osfiles.s7i the functions makeParentDirs() and convDosPath() have been improved. Now convDosPath() and stri_to_standard_path() use the same algorithm to map from a DOS/Windows path to the Seed7 standard path representation. - The function strChChRepl() has been added to str_rtl.c. - The program chkccomp.c has been improved to define the macros REMOVE_REATTEMPTS, SETENV_ALLOWS_KEY_WITH_EQUALS_SIGN and GETENV_ALLOWS_KEY_WITH_EQUALS_SIGN. - The functions determineDb2Defines() and determineSqlServerDefines() have been added to chkccomp.c. - The names of database DLLs (shared libraries) has been moved from the makefiles to chkccomp.c. - The database driver sql_odbc.c has been refactored to be based on sql_cli.c. Most of the contents of sql_odbc.c has been moved to sql_cli.c and sql_odbc.c now includes sql_cli.c. - The new database drivers sql_db2.c (for DB2) and sql_srv.c (for SQL Server) have been added. Like sql_odbc.c this drivers also include sql_cli.c. - In cmd_rtl.c the function cmdChdir() has been improved to use an extended length path only, if it is absolutely necessary. In Windows an extended length path starts with \\?\ and can have a length greater equal 260. Many subprocesses cannot handle a current working directory with an extended length path. - The makefiles mk_msvc.mak and mk_clangw.mak have been improved to write INI files with all environment variables. The INI files are seed7/bin/cl_env.ini and seed7/bin/clangenv.ini. This INI files contain the environment variables necessary to use the C compiler. - The program setpaths.c has been improved to optionally write a definition of the macro CC_ENVIRONMENT_INI to version.h. The macro CC_ENVIRONMENT_INI defines the path of seed7/bin/cl_env.ini or seed7/bin/clangenv.ini. - Support for the configuration values CC_ENVIRONMENT_INI and DATABASE_LIB has been added to cc_conf.s7i and cmd_rtl.c (in cmdConfigValue()). - The function unsetenv7() has been added to cmd_unx.c. - In gkb_x11.c and gkb_x11.c the functions gkbGetc() and gkbKeyPressed() have been improved to support KEY_MOUSE_FWD and KEY_MOUSE_BACK.

The function wstri_to_cstri8() has been added to do the conversion. - The file db_odbc.h has been improved to define wide character functions instead of ASCII functions. This was needed by sql_srv.c because it links dynamically to sqlsrv32.dll, which only defines wide character functions. 20191020: - The support for Emscripten has been improved to allow the compilation of Seed7 programs. - Improvements have been done in sql_odbc.c to support the connection with a DB2 database. - Testcases for pos() and rpos() have been added to chkstr.sd7. - The compiler has been improved to optimize the functions pos() and rpos() (actions STR_POS, STR_RPOS, STR_CHPOS, STR_RCHPOS). - The program setwpath.c has been improved to work correct in more situations (E.g.: If no PATH variable exists, if the path to be added is a substring of an existing path, if the first path in the PATH variable is to be removed, if there is only on path in the PATH variable and this path is to be removed). - In fil.unx.c the function setupFiles() has been improved to mount the file systems for Emscripten and node.js with a better strategy. - In sql_odbc.c the function sqlStmtColumnName() has been improved to work with one call of SQLColAttributeW(), if the length of the column name is below a limit. Additionally a parameter of NULL as destination for the name has be replaced by a valid address. The usage of NULL triggered an error with DB2. - The configuration value LINKED_PROGRAM_EXTENSION has been added to cc_conf.s7i. The linker produces a file with the extension defined by LINKED_PROGRAM_EXTENSION. Usually LINKED_PROGRAM_EXTENSION is identical to EXECUTABLE_FILE_EXTENSION. Except for Emscripten where, the value is ".js". - The makefiles mk_emccl.mak and mk_emccw.mak have been improved to define LINKED_PROGRAM_EXTENSION. - The compiler (s7c.s7i), the function getProgramName() in arr_rtl.c, the function cmdConfigValue() in cmd_rtl.c and the program chkccomp.c have been improved to use LINKED_PROGRAM_EXTENSION. - In chkccomp.c the function determineEnvironDefines() has been improved to determine, if getenv() works case sensitive. A definition of GETENV_IS_CASE_SENSITIVE, with a value of 0 or 1, is written to version.h. - The function getSearchPathDelimiter() has been added to cmd_rtl.c. This function is used if SEARCH_PATH_DELIMITER is 0. In this case the search path delimiter must be determined at run-time. - The function systemForNodeJs() has been added to cmd_rtl.c. This function is used for Emscripten and node.js as replacement for the C run-time library function system(). - The files sql_fire.c, sql_lite.c, sql_my.c, sql_oci.c, sql_odbc.c and sql_post.c have been improved to work correct, if no database include file could be found. Normally this should not happen, because Seed7 can provide its own database include files. - The functions getenv7() and setenv7() have been added to cmd_unx.c. This functions are used for Emscripten, because of a limitation in the Emscripten implementations of getenv() and setenv(). - Documentation comments have been improved in external_file.s7i, file.s7i, leb128.s7i, scanfile.s7i, scanstri.s7i and string.s7i. - Comments explaining the usage of undefined behavior have been added to arrlib.c, bstlib.c, set_rtl.c and strlib.c. 20190919: - A chapter about the database abstraction API has been added to the manual. - In the manual the chapters about primitive actions and about the foreign function interface have been improved. - An explanation of the Seed7 installer and about the download of Seed7 have been added to the FAQ. - The new library ico.s7i has been added. This library supports the ICO image file format. - The library browser.s7i has been improved to be more robust regarding network events. - The database drivers have been improved to raise a DATABASE_ERROR, if the database library could not be found. The error message of the DATABASE_ERROR contains the name of the missing DLL respectively shared object library. - Documentation comments have been improved in 85 library/include files (*.s7i). Wrong usages of the word "when" have been replaced by "if". - Documentation comments have been improved in 96 C source files. Wrong usages of the word "when" have been replaced by "if". - Texts in 9 Seed7 programs (*.sd7) and in a lot of documentation files have been improved. Wrong usages of the word "when" have been replaced by "if". 20190819: - A definition of SQL_DRIVER_NOPROMPT has been added to db_odbc.h.

E.g.: For Emscripten chkccomp.c is compiled with gcc, but the checked C compiler is emcc. - In chkccomp.c the function determineFseekFunctions has been improved to check fseek() and ftell() without access to the local files. - In chkccomp.c the functions to configure access to PostgreSql, Oracle and Firebird databases has been improved. - In chkccomp.c code to determine NULL_DEVICE, HAS_CDECL, HAS_STDCALL, INTPTR_T_DEFINED, PRINTF_ROUNDING, LINE_DIRECTIVE_ACCEPTS_UTF8, HAS_SETJMP and HAS_SIGSETJMP has been added or improved. - The file sigutl.c has been improved to work correct, when neither signal() nor sigaction() are present. - Log functions have been added or improved in con_emc.c, con_inf.c, sql_my.c, sql_post.c and timlib.c. - Exprerimental code has been added to con_emc.c.	2019-04-08 10:58:18 +00:00
Pietro Cerutti	cb80da6344	lang/seed7: update to 05_20190303 ... 20190303: - The makefile mk_tcc_l.mak has been added. This makefile supports compiling with the tcc C compiler under Linux. - The makefile mk_tcc_w.mak has been added. This makefile is experimental and supports compiling with the tcc C compiler under Windows. - The example program brainf7.sd7 has been added. Brainf7 is a Brainfuck interpreter. - The example program hilbert.sd7 has been added. Hilbert displays a Hilbert curve. - The example program queen.sd7 has been added. Queen solves the n queen problem. - The example program spigotpi.sd7 has been added. Spigotpi writes digits of PI with a spigot algorithm. - The new library csv.s7i has been added. This library supports converting to and from comma-separated values (CSV). - Several improvements in the Seed7 compiler (s7c) have been done: - In flt_act.s7i the function to process FLT_ISNAN has been improved to make sure, that the argument of the isnan() macro never contains preprocessor directives (e.g. #line directives). Some C compilers do not allow preprocessor directives in the argument list of a macro. Many thanks go to Alexander Vlasov for reporting this problem and for his help to find a solution. - In comp/str_act.s7i the function optimize_str_cat has been improved to assign the constant parts of strConcatN() outside of the actual expression. This might open possibilities to optimize the expression. - The function process_forward_declaration in the compiler (s7c) has been improved to avoid, that a prototype of a forward declared function, is written twice. - The function process_dynamic_param_implements has been improved to generate a switch-statement instead of an if-then-else chain. Additionally double entries are avoided now. - The function process_const_func_call has been improved to assign c_params.temp_assigns to c_expr.temp_assigns instead of c_expr.temp_decls. - The function processFuncValue has been improved to define the type and the function of the actual name parameter only once (with defineActualFuncParam()). A redefinition could happen when functions, that call functions with name parameters, are inlined. - The handling of the option -te (trace exceptions) has been improved. - The function process_const_func_declaration() has been improved to request, that for functions using the result mechanism the result is returned, when possible, as c_expr.expr_result. This way process_return_value() does not need to copy this string values. E.g. When the result of intStrToBuffer(), chrCLitToBuffer(), chrStrMacro(), strHeadSlice(), chrStrMacro() or strTailSlice() is used as the result value of a user defined function. - The function defineFunctype has been added and the function getAnyParamToTempAssigns has been improved to provide addresses of plain INTOBJECT, FLOATOBJECT, CHAROBJECT, STRIOBJECT and BSTRIOBJECT values. In this case the address is taken from a temporary variable. - In write_file_head() and init_type_constants() the creation of type constants has been improved. - The functions skip() and copyFile() have been added to file.s7i. - The function makeParentDirs() has been added to osfiles.s7i. - In cli_cmds.s7i the function doMkdirCmd has been improved to call the new function makeParentDirs(). - In tar_cmds.s7i the functions tarXtract and tarCreate have been improved to avoid, that the whole file is read into a string. This avoids a MEMORY_ERROR, when the file does not fit into a string. - The function tarXtract has been improved to extract empty regular files and to create non-existing parent directories (with makeParentDirs()) - In gzip.s7i the functions openGzipFile(), close() and write() have been improved, to write the compressed data in blocks with a maximum size. This avoids a MEMORY_ERROR, when huge files are compressed. - In gzip.s7i the function openGunzipFile has been changed to have a file as parameter instead of a string. This way it is not necessary to read the whole compressed data into a string. - A variant of the function readGzipHeader has been added to gzip.s7i. - A variant of the function getAsciiz has been added to bytedata.s7i. - A variant of the function crc32 has been added to crc32.s7i. - The program ftp7.sd7 has been improved to support the commands !ls -l, !dir, !ls, !pwd, !mkdir and !rmdir. - The function noCtrlChars has been removed from db7.sd7 and sql7.sd7 and added to seed7_05.s7i. - The program chkchr.sd7 has been has been improved to check the functions literal() and c_literal(). - Tests for the function str(), when str() assigned to a variable and when str() is called via a function, have been added to chkint.sd7. - Tests for aString[.. pos], aString[pos ..], aString[pos1 .. pos2], aString[pos len length], when they are called via a function, have been added to chkstr.sd7. - The example program chkdb.sd7 has been improved to test decimal and numeric fields with negative values. - In x509cert.s7i the constant stdCertificate has been improved to have a new validity (until end of 2021). - The program chkccomp.c has been improved to determine, if preprocessor directives are allowed in the argument list of a macro invocation (DIRECTIVES_IN_MACRO_ARGUMENTS_OK). - In fil_rtl.c the functions filBigLng() and filLng() have been improved to determine the file length always with os_fseek and os_ftell. This guarantees that the correct length is returned, when data is written to a file and it has not been flushed. - The function ftelli64Ext() has been added to fil_win.c. This function is used when fseeki64() is available and ftelli64() is missing. Either fgetpos() or _telli64() is used to implement ftelli64Ext(). - Calls of logFunction have been added in ref_data.c and typ_data.c. - In sql_my.c the function sqlBindDuration() has been improved. - In sql_odbc.c the function getNumericAsCStri() has been added. - In sql_odbc.c the function getNumericFloat() has been improved to convert a SQL_NUMERIC_STRUCT to a double via the decimal representation. - In sql_post.c the functions getNumericAsCStri(), getNumericAsStri() and getNumericAsFloat have been improved. - The program chkccomp.c has been improved to define the macros 'os_isatty' and 'os_fileno', when the functions isatty() and fileno() are not available. - A definition of 'isatty' and 'fileno' has been added to os_decls.h. - The mechanism to check for stack overflow has been improved.

Depending on the run-time library malloc(0) may return NULL, which would wrongly trigger a MEMORY_ERROR. The improvement recognizes this situation and avoids calling malloc(0). Other places in the database drivers, where malloc(0) could be called have been fixed also. - The database driver sql_fire.c has been improved: - Now the cursor of a prepared statement is closed (with isc_dsql_free_statement), when a parameter is bound to it. - The opening of a database now appends the extensions .fdb and .gdb, when trying to open the database. - The database driver sql_my.c has been improved: - The function processEscapesInStatement has been renamed to processStatementStri. Now it removes comments from the statement string. - The local variable 'param' has been introduced in the parameter binding functions. This improves readability by avoiding many accesses to the param_array. - The local variable 'columnData' has been introduced in the column accessing functions. This improves readability by avoiding many accesses to the result_array. - The function sqlColumnFloat has been improved to accept integer fields with all sizes. - The database driver sql_oci.c has been improved: - Now there is a check if all parameters of a prepared statement are bound.

This improves readability by avoiding many accesses to the param_array. - The local variable 'columnData' has been introduced in the column accessing functions. This improves readability by avoiding many accesses to the result_array. - The database driver sql_odbc.c has been improved: - The maximum number of concurrent activities is determined. If the number of concurrent activities is limited the function sqlExecute() fetches all results and stores them in a prefetch buffer. This way several prepared statements can be used in parallel even when the ODBC driver does not support concurrent activities. - The structure resultDescrRecord has been introduced. It contains the result properties of a prepared statement column. The structure resultDataRecord has been reduced to just contain the actual data buffer and length of a result field. - The functions freeFetchData, freeFetch, freePrefetched and processStatementStri have been added. The function processStatementStri removes comments from the statement string. This avoids problems with some ODBC drivers. - The functions bindResultColumn, bindResult, copyNonBlobBuffers, moveBlobBuffers, copyFetchData, prefetchOne, prefetchAll and doFetch have been added. - Now the cursor of a prepared statement is closed (with SQLFreeStmt), when a parameter is bound to it. - The function sqlColumnFloat has been improved to accept integer fields with all sizes. - The database driver sql_post.c has been improved: - The function processBindVarsInStatement has been renamed to processStatementStri. Now it removes comments from the statement string. - The local variable 'param' has been introduced in the parameter binding functions. This improves readability by avoiding many accesses to the param_array. - The function sqlColumnFloat has been improved to accept integer fields with all sizes. - The example program chkdb.sd7 has been improved.

The tests with integer fields retrieve the fields now also as floats. - Interpreter and compiler have been improved to support the new actions SQL_DRIVER, STR_FOR_KEY and STR_FOR_VAR_KEY. - The library forloop.s7i has been improved to use the new actions STR_FOR_KEY and STR_FOR_VAR_KEY. - Checks for string for loops have been added to chkstr.sd7. - The library sql_base.s7i has been improved to support the new functions driver() and getTableNames(). The function getTableNames returns a list of user table names. - The function sqlDriver has been added to sql_rtl.c.	2019-03-12 13:38:27 +00:00
Pietro Cerutti	7a0d846e25	lang/seed7: update to 05_20190107 ... 20190107: - A chapter about the handling of errors in interpreter and run-time library has been added to the manual. - The new database driver sql_fire.c has been added. This driver provides database access functions for Firebird/InterBase. - The database drivers sql_lite.c, sql_my.c, sql_odbc.c and sql_post.c have been improved to check that all parameters of a prepared statement are bound.

This function assures that string literals in prepared statements do not allow backslash escape sequences (e.g. \n or \t). This way a backslash in a SQL statement has no special meaning (like it is common practice in all other SQL databases). - The function sqlExecute() has been improved to call mysql_stmt_store_result(). This way the complete result set is buffered on the client. Doing so avoids the "Commands out of sync" error (e.g. which is triggered (without mysql_stmt_store_result()), when a new statement is prepared before all data of an old statement is fetched). - The function resizeBindArray() has been removed. - The database driver sql_odbc.c has been improved: - The function SQLGetTypeInfo is used to determine if the driver supports the type SQL_WCHAR. - It is recognized when the function SQLDescribeParam() is missing and reasonable default values are used instead. - The function SQLFreeStmt() is used now without the precondition fetchOkay or fetchFinished. - The function setupParameterColumn has been introduced. This function allocates memory for parameter buffers. - One call of SQLDescribeCol() is used to determine the properties of result columns instead of many calls of SQLColAttribute(). - Blob result data is now recognized by data type (SQL_LONGVARCHAR, SQL_WLONGVARCHAR or SQL_LONGVARBINARY) instead of data length. - The bind functions have been improved to use a switch depending on the data type. - Calls of SQLBindParameter() have been changed to use parameters determined with SQLDescribeParam(). - At several places switch statements depending on the c_type are used. - The function sqlColumnDuration has been improved to accept a duration in a VARCHAR field. - Experimental code to search for an ODBC driver has been added (but it is deactivated for now). - The database driver sql_post.c has been improved: - The function setupParameterColumn() has been introduced. This function allocates memory for parameter buffers. The buffers are part of the bindDataRecord. - The conversion of the internal NUMERIC representation to integer, float, bigInteger and bigRational values has been improved. Now sqlColumnInt() and sqlColumnFloat() can also read NUMERIC data. - The functions getNumericAsCStri(), getNumericAsStri(), getNumericAsInt(), getNumericAsBigInt(), getNumericAsBigRat() and getNumericAsFloat() have been added. - The function sqlColumnStri() has been improved to read BLOB data. - The memory management has been improved to recogize out of memory situations reliable. - The handling of exceptions has been improved. - The function literal() has been added to bigint.s7i, bigrat.s7i, boolean.s7i, bstring.s7i, duration.s7i and time.s7i. - The function integer (it converts a bigInteger to an integer) has been added to bigint.s7i. - The function string (it converts a bstring to a string) has been added to bstring.s7i. - The example program chkdb.sd7 has been improved to test the functionality of a database with much more detail. Chkdb.sd7 now supports parameters to specify the database to be checked. - The programs sql7.sd7 and db7.sd7 has been improved to support Firebird/Interbase databases. - The tests of shift operators have been improved in chkbig.sd7. - The program chkccomp.c has been improved to determine the settings for directory access and for the database driver sql_fire.c. - An #if instruction has been added to dir_win.c, soc_none.c and soc_rtl.c, such that the object file can always be linked. - The function stri_to_cstri8_buf() has been changed to work without err_info parameter. - Experimental code, to avoid the gmp error "overflow in mpz type" for shift operations, has been added to big_gmp.c. - In big_rtl.c, big_gmp.c and big_drv.h the functions bigToInt16(), bigToInt32() and bigToInt64() have been changed to have the additional parameter err_info. - The function setupBig() has been added to big_rtl.c and big_gmp.c. Additionally interpreter and compiler have been improved to call setupBig(). - Documentation comments have been improved in integer.s7i, sql_base.s7i, big_gmp.c, big_rtl.c, sql_rtl.c, intlib.c, int_rtl.c and striutl.c - The file soc_dos.c has been renamed to soc_none.c.	2019-01-09 12:58:22 +00:00

Pietro Cerutti	83120e0c21	lang/seed7: update to 05_20180601 ... 20180601: - The library tls.s7i has been improved to support the server_name extension and to process handshake messages, that extend over several tls message records. Additionally TLS version 1.2 is used now. - The library x509cert.s7i has been improved to accept a validity with times in GeneralizedTime data elements (additionally to times in UTCTime data elements). - The library browser.s7i has been improved to support calling Safari under Mac OS X. - Tests for the functions environment(), getenv() and setenv() have been added to chkcmd.sd7. - A test that checks the sorting of an array of strings has been added to chkstr.sd7. This checks the compare() function for strings. - The compiler s7c has been improved to create better code for the option -tf (trace functions). Now the trace functions are added after the declarations (such that older C compilers will accept this also). - In chkflt.sd7 tests for NaN have been grouped together. - In chkovf.sd7 tests for the binomial coefficient have been split into groups. - The program chkccomp.c has been improved to define the macros LIMITED_CSTRI_LITERAL_LEN, LIMITED_ARRAY_LITERAL_LEN, DECLARE_OS_ENVIRON, USE_GET_ENVIRONMENT, INITIALIZE_OS_ENVIRON, DEFINE_WGETENV, DEFINE_WSETENV, os_environ, os_getenv, os_setenv, os_putenv, DELETE_PUTENV_STRING, DEFINE_WSTATI64_EXT, DEFINE_STRUCT_STATI64_EXT, DEFINE_FSTATI64_EXT, os_lstat, os_stat, os_fstat, os_stat_struct, os_fstat_struct, HAS_SELECT and HAS_MMAP. - In int_rtl.c the macro DECIMAL_DIGITS has been improved to work with unsigned numbers. - In str_rtl.c the function strCmpGeneric() has been changed back to the old behaviour. Now strCmpGeneric() and strCompare() have again the same behaviour. It has turned out that sorting an array of strings worked wrong, when the program was compiled. - In pcs_win.c the function prepareCommandLine has been improved and the function copyQuotedPart has been added. Now the command line created for CreateProcessW() has fewer quoted parameters. Now parameters that contain a space or a quotation (") or a control character or a character byond ASCII are quoted. All other parameters are not quoted. - Definitions of USE_MMAP, os_environ, os_fstat, DEFINE_WSTATI64_EXT, os_lstat, os_stat, os_stat_orig, os_stat_struct, os_fstat_struct, DEFINE_WSETENV, os_setenv, os_putenv and USE_DIRENT have been removed from the makefiles. - In several files usages of USE_MMAP have been replaced by usages of HAS_MMAP. - The file read_me.txt has been updated. - In chkccomp.c the functions checkForLimitedArrayLiteralLength() and determineStatFunctions() have been added and the functions determineEnvironDefines() and determineBigIntDefines() have been improved.

This function returns a random element from a hash set. - The compiler (s7c) has been improved to generate code that uses memcpy or memmove to copy and create arrays of simple value types (e.g. array integer). The destruction of arrays of simple value types has also been simplified. - The compiler has been improved to optimize the action SET_RAND. - The compiler optimizations for the actions SET_DIFF, SET_UNION and SET_UNION_ASSIGN has been improved. - In the compiler (in comp/const.s7i) the actions BLN_ICONV1, BLN_ICONV3, CHR_ICONV3 and SET_RAND have been added to the list of special actions. The compiler implements functions, which just call one of the special actions as inline functions. - Interpreter and compiler have been improved to support the actions HSH_RAND_KEY and SET_INTERSECT_ASSIGN. - Tests for the functions card() and rand() for the type set of string have been added to chkset.sd7. - Tests for intersection assignments ( &:= ) have been added to chkset.sd7. - In s7c.sd7 the code to call C compiler and linker has been refactored. - The compiler has been improved (in comp/prc_act.s7i) to use the function hshIdxDefault0() instead of hshIdxWithDefault() for case statements with hashsets. - The code generation of the compiler has been improved to trigger the signal SIGFPE with a call of triggerSigfpe(). - The compiler has been improved to insert diagnostic line information (e.g.: #line 64 "logfile.s7i") into code for the actions ARR_CPY, BLN_AND, BLN_OR, ITF_CPY, PRC_IF, PRC_IF_ELSIF, PRC_IF_NOOP - The compiler has been improved to insert diagnostic line information for inlined functions. - The configuration values in cc_conf.s7i have been improved. SWITCH_WORKS_FOR_INT64TYPE, CC_OPT_OPTIMIZE_1, CC_OPT_OPTIMIZE_2 and CC_OPT_OPTIMIZE_3 have been added. SYSTEM_DB_LIBS has been renamed to ADDITIONAL_SYSTEM_LIBS. HAS_SIGACTION, SIGNAL_RESETS_HANDLER and DO_SIGFPE_WITH_DIV_BY_ZERO have been removed. - The program chkccomp.c has been improved. Now it determines the name of the NULL device (/dev/null or NUL:), the system socket library (unix sockets or winsocket), the method to read directories, the bigInteger implementation used (big_rtl.c or big_gmp.c) and the support for switch statements with 64-bit values. - Documentation comments have been added or improved in bigint.s7i, integer.s7i, bitsetof.s7i, bitset.s7i, hashsetof.s7i, cc_conf.s7i, fil_rtl.c, dir_drv.h, cmd_rtl.c, set_rtl.c, str_rtl.c and striutl.c. - In set_rtl.c the function setIntersect() has been improved to create a smaller intersection result, if possible. - In set_rtl.c the function setIntersectAssign has been added. - In setlib.c the function set_intersect_assign has been added. - In hsh_rtl.c the functions get_helem_elem, get_hash_elem, hshRand and hshIdxDefault0 have been added. - In hshlib.c the functions get_helem_elem, get_hash_elem and hsh_rand_key have been added. - In gkb_x11.c and gkb_win.c the function find_window() has been improved to use hshIdxDefault0() instead of hshIdxWithDefault(). - In big_gmp.c the function bigDivRem has been improved to initialize the remainder. - In str_rtl.c and strlib.c the function strelem_memcmp has been renamed to memcmp_strelem. - In str_rtl.c the function strCmpGeneric has been changed to avoid calls of memcmp_strelem(), when the string sizes differ. This differs from the behaviour of strCompare, but the difference is not important, because strCmpGeneric() is only used for string comparisons of hash keys (in compiled programs). - In striutl.c the function conv_to_cstri has been rewritten to return the C string, when the function succeeds, and to work without the parameter err_info. - In striutl.c the function stri_to_bstriw has been rewritten to use an err_info parameter. - In striutl.c the functions with loop unrolling inspired by Duff's device have been rewritten. - In striutl.c the loops in conv_to_cstri, stri_to_cstri and conv_to_os_stri have been optimized. - The macro castIntTypeForSwitch has been introduced to support C compilers, that do not support switch statements with 64-bit values. - Definitions of NULL_DEVICE, USE_GETADDRINFO, USE_WINSOCK and BIGINT_LIB_DEFINE have been removed from the makefiles. 20180401: - The new library logfile.s7i has been added. It defines the interface logFile. A logFile works like a normal file unless the log file has the value STD_NULL. When a logFile has the value STD_NULL string expressions written to the logFile are not evaluated. This reduces the overhead, when logging is turned off. - The bas7.sd7 (basic interpreter) example program has been improved. The logging is now done via the new logFile type. This improves the performance, when no logging is done. Several DATA statements in one line are processed correctly now. Support for IF GOSUB and DISPLAY statements and for the function COMMAND$ has been added. - Tests of nested bigInteger for loops have been added to chkbig.sd7. - A test with the assignment of a hash variable to itself have been added to chkhsh.sd7. - Tests of the replace function have been added to chkstr.sd7. - In striutl.c the functions conv_from_os_stri, cstri8_to_stri and cstri8_buf_to_stri have been improved. Now they call realloc() only, when the size has changed. This improves the performance of conv_from_os_stri by 32% (measured with gcc and valgrind, when reading a directory). - In str_rtl.c the function strUtf8ToStri has been improved to call realloc() only, when the size has changed. - In cmd_rtl.c the functions add_stri_to_array and complete_stri_array have been renamed to addStriToRtlArray and completeRtlStriArray respectively. The renamed functions have also been improved to work with a simpler parameter list. Together with the improvement of conv_from_os_stri this improves the performance of cmdLs by 14% (measured with gcc and valgrind, when reading a directory). - In cmdlib.c the function cmd_ls has been rewritten to be based on cmdLs. The functions cmp_mem and read_dir have been removed. - In cmdlib.c the main loop in the function toArrayType has been optimized for performance. - In str_rtl.c the function add_stri_to_array has been renamed to addCopiedStriToRtlArray and the function completeRtlStriArray has been introduced. The code of addCopiedStriToRtlArray has also been improved to work with a simpler parameter list. - In strlib.c the function add_stri_to_array has been renamed to addCopiedStriToArray and the functions freeStriArray and completeStriArray have been introduced. The code of addCopiedStriToArray has also been improved to work with a simpler parameter list. - The compiler has been improved to optimize the action HSH_CONTAINS, when the hash table is constant and contains one element. - In the compiler (in comp/const.s7i) the actions BLN_ORD, CHR_ICONV1, CHR_ORD and INT_ODD have been added to the list of special actions. The compiler implements functions, which just call one of the special actions as inline functions. This allows optimizations for the boolean and char random number generator. - The compiler (s7c) has been improved (in comp/destr.s7i) to define interface destructors, which take all possible implementation types into account. Additionally a switch statement is used instead of an if-then-else chain. Double entries are also avoided now. - The function strChRepl has been added to str_rtl.c. - The compiler has been improved to use strChRepl instead of strRepl, to optimize split operations. - Unnecessary function parameters have been removed in several include files of the compiler. - In flt_rtl.c the function doubleToCharBuffer has been improved to determine the integer value of the exponent without calling strtol(). - The function freeRtlStriArray has been added to arr_rtl.c. - Several #define flags in pol_sel.c have been improved. - The macro CSTRI_LITERAL_TO_STRI has been defined in striutl.h and used in analyze.c, arr_rtl.c, cmd_rtl.c, cmd_unx.c, infile.c, pcs_unx.c and pcs_win.c. - Calls of logError have been added to functions in cmd_rtl.c, con_inf.c, prclib.c, soc_rtl.c, tim_dos.c, tim_rtl.c, tim_unx.c and tim_win.c. - Documentation comments have been added or improved in cmdlib.c, int_rtl.c and tim_rtl.c.	2018-06-04 13:41:59 +00:00

This allows e.g. case statements with string, bigInteger, type and other expressions. - Several discrepancies between s7 and s7c have been fixed. Many thanks go to "tipd bmp" who sent a example programs to show the discrepancies. Thanks also for finding a bug in the manual. - The following type conversion functions from integer have been introduced: bigInteger(), bigRational(), bitset(), boolean(), char(), float(), rational() and complex(). This fits to the existing conversion functions bin32() and bin64(). - The files bigrat.s7i, filesys.s7i, int_act.s7i, s7c.sd7, chkdb.sd7, dnafight.sd7, printpi1.sd7, printpi2.sd7 and savehd7.sd7 have been adjusted to use bigInteger() instead of the conv operator to convert an integer to a bigInteger. - The function bigRational, which converts a string to a bigRational number, has been added to bigrat.s7i. - The function rational, which converts a string to a rational number, has been added to rational.s7i. - In rational.s7i the operator 'parse' has been improved to convert a string with a decimal number to a rational number. - The functions float2Bits and bits2Float in bin32.s7i and bin64.s7i are deprecated and will be removed in a future version.

Pietro Cerutti	873a113ffa	lang/seed7: update to 05_20170501 ... With this update, lang/seed7 depends on a number of database client libraries (MySQL, SQLite, unixODBC and PostgreSQL). The reason for this is that the configuration stage doesn't allow to specify which database drivers to use, but rather automatically links against what's installed. This would cause non-tracked dependencies in the case the user building the port happens to have any of the drivers installed at build time. 20170501: - The example program diff7.sd7 has been added. This program compares two files line by line. - The example program hd.sd7 has been added.

This functions read bits from a file in the direction from LSB (least significant bit) to MSB (most significant bit). - The operator |:= has been added to the libraries bitsetof.s7i and bitset.s7i. - The type void has been improved to allow writing a void value. This allows that calc7.sd7 can execute procedures. - The new library inflatefile.s7i has been added. It allows to uncompress data from a file with the Inflate algorithm. In contrast to inflatefile.s7i the functions from inflate.s7i assume that the compressed data is in a string. - A test of the tar header checksum has been added to tar.s7i. - A support for long link paths has been added to tar.s7i. - The function readMinimumOfHead has been added to tar.s7i. With this function opening a tar archive can be done faster. - The functions fileMode and getMTime in zip.s7i have been improved to recognize modes and times from different operating systems. - In zip.s7i the function rposOfMagic has been improved to work with one call of seek() and one gets(). This way the function is faster, when the file is not a ZIP file. - In zip.s7i the functions get_local_header, get_central_header and get_end_of_central_directory have been improved to read the fixed size part of the header with one statement and to convert the data afterwards. This improves the performance of get_central_header by about 10%. - In zip.s7i a map of extra header fields has been introduced. - In zip.s7i the function getContent has been renamed to getFile. Additionally the function has been improved to work when the local header does not contain the compressed size. In this case the new library inflatefile.s7i is used. - The function timestamp1601ToTime has been added to time.s7i. - A test for the operator |:= has been added to chkset.sd7. - The function filGets in fil_rtl.c has been improved to recognize a request to read zero characters earlier.

This is activated with the option -tf. - Checks have been added to chkint.sd7, where several terms are added in combination with the functions succ or pred. - The functions wstati64Ext (in stat_win.c) and alternate_utime (in tim_win.c) have been improved to avoid the strange time adjustments of windows for Daylight Saving Time: For the same file different times are retrieved respectively set in summer and winter. Now the times do not depend on the time when they are retrieved or set. - In stat_win.c a check for wildcards in a path has been removed from wstati64Ext. - The performance of dirRead in dir_rtl.c has been improved by 10% (measured with gcc and valgrind). A smarter check for the directories . and .. reduces the CPU time used. - In cmd_rtl.c the functions remove_dir and copy_dir have been improved with a smarter check for the directories . and .. to reduce the CPU time used. - The function getSearchPath in cmd_rtl.c has been improved to work correctly, when there is no environment variable named PATH. - Definitions of macros to check the st_mode field of struct stat (e.g. S_ISDIR, S_ISREG, etc.) have been moved from fil_rtl.h to stat_drv.h. - The program chkccomp.c has been improved to work correct, when C compiler options are separated by linefeeds (\n). In this case the linefeeds are replaced by spaces. The linefeeds are used in cc_conf.s7i to allow the definition of SYSTEM_DB_LIBS as an array of database libraries. - In sudo.c the call of ShellExecute() has been replaced by a call of ShellExecuteA(). - A definition of FMT_T, a printf format for time_t values, has been added to common.h. - The makefile mk_clangw.mak has been improved to use the library extension ".lib". - Calls of logFunction and logError have been added or improved in cmd_rtl.c, cmd_win.c, gkb_win.c, flt_rtl.c, int_rtl.c, pcslib.c, reflib.c, rfllib.c, stat_win.c and tim_win.c. - In dir_rtl.c the function readVolumeName has been improved to consider only directories as volumes. - In int_rtl.c the functions uint_mult, uint2_mult and uint2_add have been renamed to uintMult, uint2Mult and uint2Add respectively. - In stat_win.c the functions filetime_to_unixtime and fileattr_to_unixmode have been renamed to fileTime2UnixTime and fileAttr2UnixMode respectively. - In tim_win.c the function alternate_utime has been improved to avoid calling os_utime_orig, because the utime functions of Windows do different time adjustments for the same time in summer and winter.	2017-01-02 17:47:52 +00:00
Pietro Cerutti	9af570eb34	lang/seed7: update to 05_20161031 ... - The examples about multiple dispatch in the FAQ and in the manual have been changed. - In dir_win.c the functions opendir and wopendir have been improved to work correctly, when a volume is empty. FindFirstFile returns INVALID_HANDLE_VALUE, when the path refers to an empty volume (a directory that does not contain the . and .. directories). After FindFirstFile fails GetFileAttributesEx is used to recognize empty volumes. - In stat_win.c the function wstati64Ext has been improved to recognize empty volumes correctly. Now GetFileAttributesEx is used instead of FindFirstFile to get information about a file. - The function openVolumeList has been moved from cmd_win.c and cmd_unx.c to dir_win.c. - The definition of volumeListType has been moved from cmd_drv.h to dir_win.h. - In str_rtl.c the function strAppendN has been improved to work correctly, when an appended string is identical to the destination or a slice of it. There was already code to handle this case, but this code could access freed memory in rare situations. - The makefiles mk_nmake.mak and mk_msvc.mak have been changed to include the file 'macros' before the macro SYSTEM_DB_LIBS is used. - Rand functions have been added to bin32.s7i and bin64.s7i. - The compiler has been improved to optimize the float shift operators << and >> . - Documentation comments have been improved in float.s7i, integer.s7i, osfiles.s7i, big_gmp.c, big_rtl.c, bstlib.c and bst_rtl.c.	2016-11-23 12:39:53 +00:00

Pietro Cerutti	b3a83969da	- Update to 05_20140907 ... Changes: * The function setSearchPath has been added to the library process.s7i. * The compiler has been improved to write an error message, when the sets of a case-statement overlap. Until now this situation was only recognized by the C compiler. * The interpreter has been improved to raise an exception, when the current value of a case-statement is element of two sets. * There have been changes in the libraries makedata.s7i and make.s7i. * The macro expansion in makedata.s7i has been changed. Now all macro expansions (except the expansions of internal macros) are done with the function applyMacros. * In makedata.s7i the function applyMacros has been improved to process the makefile macro functions wildcard, error and warning. * The functions evalFunction and getMacro, that where used to do macro expansion when the makefile is read, have been removed. * The code to read the definition of recursively expanded variables has been changed to do no macro expansion. This macros are expanded when they are used. * The library make.s7i has been improved to read the parameters for the commands rm, cp, and mv as Unix shell parameters (with the function getUnixCommandParameter). * The library make.s7i has been improved to read the parameters for the commands del, copy, xcopy and move as Dos/Windows batch parameters (with the function getDosCommandParameter). * Interpreter and compiler have been improved to support the action CMD_SET_SEARCH_PATH. * The batch file bin/call_gcc.bat has been changed to work correctly, when it is called from any directory. * Writing error messages in error.c has been changed to use prot_... functions instead of printf.	2014-09-10 06:58:49 +00:00
Pietro Cerutti	2cac42ef5a	- Update to 05_20140817 ... Changelog: * The chapter about files in the manual has been improved. * Variants of the for-each-loop with an until condition have been added to array.s7i. * The parse operator for characters has been improved to accept only strings with a length of 1. * The function trimValue has been introduced. This function trims a string such that it can be converted to a specified type. * The exception handlers for RANGE_ERROR have been removed from the functions read and readln in enable_input.s7i. The functions read and readln now raise range RANGE_ERROR when the conversion to the target type fails. * Occurances of io_ok, io_error, io_empty and io_filled have been removed from the libraries. This undocumented feature was not used for years. The function succeeds and the functions read and readln with default value are better suited for error checking, when data is read. * The exception handlers in interpreter and compiler have been improved to allow an otherwise part. * The function succeeds has been introduced. This function executes a statement and returns TRUE when no exception occurs. * The example programs nicoma.sd7 and savehd7.sd7 have been improved to use the new function succeeds. * The parse operator for float has been changed to raise RANGE_ERROR when leading whitespace is found. * The library make.s7i has been improved to accept the commands erase, xcopy, mv, move and rem. * The library makedata.s7i has been improved to accept the macro functions subst and patsubst. * The reading of rules in makedata.s7i has been improved to read commands without macro substitution. The macros in commands are substituted just before the commands are executed. * The make functions in make.s7i have been changed to raise FILE_ERROR when a command fails. * The function applyMacros in makedata.s7i has been improved to accept macro functions and the shorthands of patsubst. * The function replaceSuffixes in makedata.s7i has been improved to accept pattern substitution with the % character. * In the library make.s7i the logging has been removed from the functions doRm, doCp, doPwd, doEcho, doCd, doMake, doOneCommand, doCommands and processCommand. * The program chkflt.sd7 has been adjusted to work with the strict parse operator for float. * Interpreter and compiler have been improved to support the actions PRC_BLOCK_CATCH_ALL and PRC_BLOCK_OTHERWISE. * The program sudo.c has been improved to work without upper limit for the parameter length. * The functions checkIfOutsideRange and negate have been added to int_act.s7i.	2014-08-28 10:36:27 +00:00
Pietro Cerutti	7d89615715	- Update to 05_20140803 ... Changes: * The handling of ctrl-c has been changed to work better under windows. * The runtime of the function intPowOvfChk in int_rtl.c has been reduced to 57% (measured with gcc and valgrind). * The generation of code in the compiler for the action INT_POW has been improved. When the base is a negative power of two the exponentiation is done with a shift instead of a call of intPow (respectively intPowOvfChk). * The overflow checking for INT_POW in the compiler has been improved. When base or exponent is known the overflow checking is done with inline code and intPow is called instead of intPowOvfChk. * Documentation comments have been added to bitsetof.s7i * Tests for ** have been added to chkint.sd7 and chkovf.st7 * The tests for * and *:= in chkovf.st7 have been reorganized. * An interrupt_flag has been introduced in the interpreter. This flag is used for exception handling and for signal handling. Exceptions set interrupt_flag and fail_flag (with the macro set_fail_flag). Signals set only the interrupt_flag (file sigutl.c). The interrupt_flag is handled in exec_action (file exec.c). * The functions signal_name, handle_signals, handle_segv_signal, handle_term_signal and activate_signal_handlers in sigutl.c have been improved. * The functions continue_question, write_curr_position and show_signal in runerr.c have been improved. * The functions handle_int_signal, readChar, doGetcFromTerminal, doGetsFromTerminal, doLineRead, doLineReadFromTerminal, doWordRead, doWordReadFromTerminal, filGetcChkCtrlC, filGetsChkCtrlC, filHasNextChkCtrlC, filLineReadChkCtrlC and filWordReadChkCtrlC have been added to fil_rtl.c. This functions support reading from a terminal with a check for ctrl*c. This functions are used by the interpreter (file intlib.c). * Tracing has been added to functions in int_rtl.c. * Configuration defines for CTRL_C_SENDS_EOF, SIGNAL_HANDLER_CAN_DO_IO and INT64TYPE_NO_SUFFIX_BUT_CAST have been added to makefiles.	2014-08-04 12:04:58 +00:00
Pietro Cerutti	364a875e6d	- Update to 05_20140720 ... Changes: * The compiler has been improved to generate overflow checking code by default. The generation of overflow checking code can be switched off with the option -so. * The exception OVERFLOW_ERROR has been introduced. It is raised by the interpreter and by compiled programs when an integer overflow occurs. * A paragraph about integer overflow and the installation of Seed7 has been added to the FAQ. * The chapter about exceptions in the manual has been improved. * The program chkovf.sd7, which checks the recogition of integer overflows, has been added. * Checks for +, -, *, rem, mod, <<, +:=, -:=, *:=, succ, pred, incr and decr have been added to chkint.sd7. * Checks for the lpad operator have been added to chkstr.sd7. * The compiler option -r has been replace by the option -sr. * The program calc7.sd7 has been improved to report MEMORY_ERROR and OVERFLOW_ERROR. * The library make.s7i has been improved such that make7.sd7 accepts echo (and echo.) statements without parameters. * The function eof has been defined for the type tlsFile in tls.s7i. * The function gets in tls.s7i has been improved. * The function getHttp in gethttp.s7i has been improved to avoid an endless loop when eof has been reached. * The function memcpy_from_strelem has been added to striutl.c. This function uses loop unrolling inspired by Duff's device and a trick with a binary or (|=) to check for allowed values. * The functions filWrite, socWrite and bstParse have been changed to use memcpy_from_strelem. The reduction in runtime has been measured with gcc and valgrind. The runtime of filWrite, socWrite and bstParse has been reduced to 53%, 61% and 56% respectively. * Documentation comments have been added to integer.s7i, bin32.s7i, intlib.c and striutl.c. * The compiler has been improved to generate overflow checking code for *, <<, >>, *:=, <<:= and >>:= . * The generation of overflow checking code for the operators rem and mod has been improved. * Checks for overflow, division by zero, numeric error and index out of bounds in compiled programs now use the macros ovfChk, divChk, numChk and idxChk. This macros inform the C compiler about the unlikeliness of an exception. * The function fltIPow has been improved to avoid a signed integer overflow, when the exponent is the most negative integer. * The primitive actions INT_ULSHIFT and INT_ULSHIFT_ASSIGN have been added and supported in interpreter and compiler. * A version of the function uint_rand, which uses 128-bit integers, has been added to int_rtl.c. * The function raise_error3 in runerr.c has been renamed to interprRaiseError. * The configuration values INT128TYPE, UINT128TYPE and MACRO_DEFS have been added to cc_conf.s7i. The configuration value SIGILL_ON_OVERFLOW has been replaced with OVERFLOW_SIGNAL. * The functions constValueIsEqual, checkRangeFromZero, process_const_int_lshift, process_const_int_lshift_assign, process_const_int_rshift_assign, process_const_int_mult, process_const_int_mult_assign, process_const_int_ulshift_assign, process_const_int_ulshift and process_const_int_urshift_assign have been added to int_act.s7i. * The function intExpr in chkbig.sd7, chkexc.sd7, chkint.sd7 and chkstr.sd7 has been changed to make sure that the C compiler cannot evaluate it at compile time. * The runtime of the functions str_lpad, strLpad and strLpadTemp has been improved.	2014-07-21 08:34:26 +00:00
Pietro Cerutti	6b5bcc894a	- Update to 05_20140706 ... Changes: * The interpreter has been improved to recognize integer overflow. Now the exception NUMERIC_ERROR is raised, when a program triggers an integer overflow. The checks for overflow are done in software, but the overhead is small. With overflow checks the interpreter needs 0.5% (zero point five percent) more run-time to execute the program chkint.sd7 (verified with gcc and valgrind). * A chapter about the Seed7 Structured Syntax Description (S7SSD) has been added to the manual. * The for-until-loops in bitset.s7i and bitsetof.s7i have been improved such that the for-variable has the correct value, when it is used in the until-condition. * The function replaceN has been added to string.s7i. This function does replacements until no occurance of the target string is left. This function is used by toStdPath to replace multiple occurances of a character by one occurance (replace("/a///b////c", "//", "/") returns "/a/b/c"). * The program calc.sd7 has been renamed to calc7.sd7. * The program calc7.sd7 has been changed to accept the commands 'quit' and 'exit'. This commands can be used to exit the program. The possibility to leave the program with an empty input line has been removed. * The program calc7.sd7 has been improved to write the name of the exception, when it has been raised. * The compiler has been improved to allow the generation of overflow checking code. Overflow checking code can be generated for the operators +, -, **, +:= and -:= and the functions abs, succ, pred, incr and decr. Until the rest of the functions is implemented and enough tests have been added to chkint.sd7 the functionality is switched off. * The template FOR_UNTIL_DECLS has been added to forloop.s7i. This template defines for-loops with a condition. * The function abs has been moved from the library math.s7i to the library float.s7i. * Checks for addition, subtraction, multiplication, power and abs have been added to chkint.sd7. * In the compiler the statements to write the C prototypes have been moved from s7c.sd7 to functions in the files comp/xxx_act.s7i (xxx is the abbreviation for the corresponding primitive type). * The functions getReference getParameterAsReference have been added to comp/expr_util.s7i. * The function isit_bool from objutl.c has been replaced by the macro isit_bool (defined in objutl.h). This improves the speed of the interpreter. * The function set_card has been improved to call setCard, which computes the cardinality of a set much quicker.	2014-07-08 07:29:30 +00:00
Pietro Cerutti	8d1ecbb00a	- Update to 05_20140615 ... Changes: * The makefile mk_freebsd.mk has been changed to work with the new version of chkccomp.c. Thanks go to Pietro Cerutti for pointing out the problem. * The self extracting Seed7 package for windows has been improved to use gcc version 4.8.1 instead of 4.5.0. * The new function removeTree, which removes a directory tree, has been introduced in osfiles.s7i. The function removeAnyFile, which has been used for the same purpose, is deprecated. Deprecated functions will be removed in a future version. * Checks for hash tables with character keys have been added to chkhsh.sd7. * The test program "chkcmd.sd7" has been added. This program checks functions that copy, move and remove files. Note that windows has race conditions when files are copied, moved and removed quickly in succession. This bug of windows cannot be fixed in a runtime library. * The function temp_name_in_dir has been added to striutl.c. * The typedef of socketType in common.h has been changed such that socketType is always int. * Functions in soc_rtl.c, pol_sel.c and pol_unx.c have been changed to use the type os_socketType. * Tracing statements in hsh_rtl.c, cmd_rtl.c, drw_win.c and drw_x11.c have been changed to use the FMT_ strings from common.h. This way the tracing is more portable. * Under Windows the functions cmdRemoveFile and cmdRemoveTree now rename a file before it is removed. When the renaming fails the directory is left intact. This avoids half removed directory trees under Windows, when a process has the current working directory somewhere in the directory that is to be removed. The renaming also lowers the probability of race conditions under Windows, but they still can happen. * The function checkMoveDirectory has been added to chkccomp.c. * The target make7 has been added to the makefiles. With 'make make7' an executable of the make7 program is generated and placed in seed7/bin.	2014-06-23 12:40:05 +00:00
