Denny <joeldenny@joeldenny.org> - - doc: clean up naming of various Bison files. - The Bison manual's names for various files associated with a Bison - parser has devolved into inconsistency. This patch makes the - naming consistent for the most important files. First, it chooses - "grammar file" over "input file". The former appears to be more - traditional in the Bison manual, and Bison has other input - files (skeletons). Second, it chooses "parser implementation - file" over names like "parser file", "parser source file", "parser - source code file", and "parser output file". The new name makes - it clearer where Bison generates the main parser implementation, - and it is easily distinguishable from "parser header file". - * doc/bison.texinfo: Implement throughout. - -2011-02-06 Joel E. Denny <joeldenny@joeldenny.org> - - doc: give credit to more of Bison's developers. - * doc/bison.texinfo (Introduction): Don't imply that only Robert - Corbett, Richard Stallman, and Wilfred Hansen have contributed to - Bison. However, I don't have time to write a full history, so - just point readers to THANKS and ChangeLog. - -2011-02-06 Joel E. Denny <joeldenny@joeldenny.org> - - doc: document experimental features better. - * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical - LR(1) are experimental. Mention Java. Normally experimental - features probably shouldn't be mentioned in the introduction. - However, if Bison's limitations to LALR(1), C, and C++ are so - important that they should be mentioned here, then it's important - to point out that Bison is beginning to escape those limitations. - Moreover, these particular experimental features have very little - chance of being removed. - * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are - experimental. - -2011-01-29 Joel E. Denny <joeldenny@joeldenny.org> - - Do not allow identifiers that start with a dash. - This cleans up our previous fixes for a bug whereby Bison - discarded `.field' in `$-1.field'. The previous fixes were less - restrictive about where a dash could appear in an identifier, but - the restrictions were hard to explain. That bug was reported and - this final fix was originally suggested by Paul Hilfinger. This - also fixes a remaining bug reported by Paul Eggert whereby Bison - parses `%token ID -123' as `%token ID - 123' and handles `-' as an - identifier. Now, `-' cannot be an identifier. Discussed in - threads beginning at - <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>, - <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>. - * NEWS (2.5): Update entry describing the dash extension to - grammar symbol names. Also, move that entry before the named - references entry because the latter mentions the former. - * doc/bison.texinfo (Symbol): Update documentation for symbol - names. As suggested by Paul Eggert, mention the effect of periods - and dashes on named references. - (Decl Summary): Update documentation for unquoted %define values, - which, as a side effect, can no longer start with dashes either. - * src/scan-code.l (id): Implement. - * src/scan-gram.l (id): Implement. - * tests/actions.at (Exotic Dollars): Extend test group to exercise - bug reported by Paul Hilfinger. - * tests/input.at (Symbols): Update test group, and extend to - exercise bug reported by Paul Eggert. - * tests/named-refs.at (Stray symbols in brackets): Update test - group. - ($ or @ followed by . or -): Likewise. - * tests/regression.at (Invalid inputs): Likewise. - -2011-01-24 Joel E.

Denny <joeldenny@joeldenny.org> - - Improve error messages for `$' or `@' followed by `.' or `-'. - Previously, for this special case of an invalid reference, the - usual "symbol not found in production:" was printed. However, - because the symbol name was parsed as the empty string, that - message was followed immediately by a newline instead of a symbol - name. In reality, this is a syntax error, so the reference is - invalid regardless of the symbols actually appearing in the - production. Discussed at - <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>. - * src/scan-code.l (parse_ref): Report the above case as a syntax - error. Other than that, continue to handle this case like any - other invalid reference that Bison manages to parse because - "possibly meant" messages can still be helpful to the user. - * tests/named-refs.at ($ or @ followed by . or -): New test group. - -2011-01-08 Joel E.

Use YYMAXDEPTH for maximum stack size given that - the stack should never need to grow larger than the main state - stack needs to grow without LAC. - (YY_LAC_ESTABLISH): Update yy_lac invocation. - (yy_lac): Add arguments for exploratory stack memory data - recorded in the main parser. Invoke yy_lac_stack_realloc when - reallocation is necessary. - (yysyntax_error): Add the same new arguments and pass them to - yy_lac. - (yypstate_delete): Free yyes if necessary. - (yyesa, yyes, yyes_capacity): #define these to yypstate members - in the case of push parsing. - (yyparse, yypush_parse): Initialize yyes and yyes_capacity. - Update yysyntax_error invocations.

See discussion at - <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>. - However, one point there must be corrected: because of %nonassoc, - LAC is *not* always redundant for lr.type=canonical-lr. - * data/yacc.c: Accept values of "none" (default) or "full" for - parse.lac. Accept %define parse.lac.es-capacity to specify - capacity of LAC's temporary exploratory stack. It defaults to 20 - and, for now, will not grow dynamically. - (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for - parse.lac!=none. - (YYBACKUP): Invoke YY_LAC_DISCARD. - (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke - yy_lac and track when it needs to be invoked - (yy_lac): New function that, given the current stack, determines - whether a token can eventually be shifted. Return status mimics - yyparse return status. - (yysyntax_error): Change yystate argument to yyssp so stack top - can be passed to yy_lac. If LAC is requested, build expected - token list by invoking yy_lac for every token instead of just - checking the current state for lookaheads. Return 2 if yy_lac - exhausts memory. - (yyparse, yypush_parse): Use local variable yy_lac_established and - cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC. - Update yysyntax_error invocation. Add yyexhaustedlab code if LAC - is requested. - * tests/conflicts.at (%nonassoc and eof): Extend to check the - effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full. - (parse.error=verbose and consistent errors): Likewise. - (LAC: %nonassoc requires splitting canonical LR states): New test - group demonstrating how LAC can fix canonical LR. - * tests/input.at (LAC: Errors for %define): New test group. - * tests/regression.at (LAC: Exploratory stack): New test group. - (LAC: Memory exhaustion): New test group. - -2010-11-21 Joel E.

- In order to make it easy to perform benchmarks to ensure that - there are no performance loss, lalr1.cc is forked into - lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace - lalr1.cc. - - Meanwhile, to make sure that lalr1-fusion.cc is correctly - exercized by the test suite, the user must install a symbolic link - from lalr1.cc to it. - - Instead of having three stacks (state, value, location), use a - stack of triples. This considerably simplifies the code (and it - will be easier not to require locations as currently does the C++ - parser), and also gives a 10% speedup according to - etc/bench (probably mainly since memory allocation is done once - instead of three times). - - Another motivation is to make it easier to destruct properly - semantic values: now that they are bound to their state (hence - symbol type) it will be easier to call the appropriate destructor. - - These changes should probably benefit the C parser too. - - * data/lalr1.cc: Copy as... - * data/lalr1-fusion.cc: this new file. - (b4_rhs_value, b4_rhs_location): New definitions overriding those - from c++.m4. - (state_stack_type, semantic_stack_type, location_stack_type) - (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove. - (data_type, stack_type, yystack_): New. - (YYLLOC_DEFAULT, yypush_): Adjust. - (yyerror_range): Now based on data_type, not location_type. - -2008-11-03 Akim Demaille <demaille@gostai.com> - - Push the state, value, and location at the same time. - This is needed to prepare a forthcoming patch that fuses the three - stacks into one. - - * data/lalr1.cc (parser::yypush_): New. - (parser::yynewstate): Change the semantics: instead of arriving to - this label when value and location have been pushed, but yystate - is to be pushed on the state stack, now the three of them must - have been pushed before. yystate still must be the new state. - This allows to use yypush_ everywhere instead of individual - handling of the stacks. - -2008-11-03 Akim Demaille <demaille@gostai.com> - - Prefer references to pointers. - * data/lalr1.cc (b4_symbol_actions): New, overrides the default C - definition to use references instead of pointers. - (yy_symbol_value_print_, yy_symbol_print_, yydestruct_): - Take the value and location as references. - Adjust callers. - -2008-11-03 Akim Demaille <demaille@gostai.com> - - stack::size instead of stack::height. - * data/lalr1.cc (stack::height): Rename as... - (stack::size): this. - Fix the output type. - Comment changes. - -2008-11-03 Akim Demaille <demaille@gostai.com> - - Use variants to support objects as semantic values. - This patch was inspired by work by Michiel De Wilde.

Now (at least), changing the - consistency label on such a state appears to have no useful effect in - any of the places it is examined, which I enumerate below. The key - point to understanding each item in this enumeration is that a state - with an error transition is labelled consistent in the first place only - if it has no rules, so the check cannot matter for states that have - rules. (1) Labelling a state as inconsistent will cause set_conflicts - to try to identify its conflicts, and a state must have *rules* to have - conflicts. (2) Labelling a state as inconsistent will affect how - action_row sets the default *rule* for the state. (3) Labelling a - state as inconsistent will cause build_relations to add lookback edges - to *rules* in that state. - * src/state.h (struct state): Word the comment for member consistent - more carefully. - -2007-05-27 Joel E.

This patch also fixes at least a bug such that yylloc was not - initialized (with b4_location_initial_line and - b4_location_initial_column) upon calling yypush_parse. However, that - initialization now overwrites the first token's location; - %initial-action assigning @$ already did the same thing, and both bugs - will be fixed in a later patch. - * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa. - (b4_declare_parser_state_variables): Remove initialization of yytoken, - yyss, yyvs, yyls, and yystacksize. - (yypstate_new): Remove initialization of some yypstate fields: yystate, - yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and - yylsp. - (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to - yyps->NAME so it can be used in yypush_parse. - (yyparse or yypush_parse): For yypush_parse, don't print the - "Starting parse" diagnostic for invocations after the first. - Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for - yypush_parse, only do it for the first invocation. - Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc - initialization to occur in yypush_parse but only on the first - invocation. - -2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> - - * data/push.c: Add CPP guards around push parser declarations in both - the header and the code file. - In the code file, move the push parser declarations to the same place - they appear in the header file. - Clean up the M4 some, especially the inconsistent underquoting in - some b4_c_function_def and b4_c_function_decl uses. - -2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> - - Encapsulate the push parser state variables into an M4 macro so the - push skeleton doesn't have to list them again for pull mode's yyparse. - For push mode, remove yypush_parse's local equivalents of these - variables to eliminate unnecessary copying between the two sets at - run-time. This patch also fixes at least a bug related to multiple - %initial-action invocations in push mode. - * data/push.c (b4_declare_parser_variables): Rename to... - (b4_declare_scanner_communication_variables): ... this for clarity and - update both uses. - (b4_declare_yyparse_variables): Remove and move its contents to the one - spot where it was invoked. - (b4_declare_parser_state_variables): New macro containing the parser - state variables required by push mode. - (struct yypstate): Replace all fields but yynew with - b4_declare_parser_state_variables. - (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs, - yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define - each NAME in this list to yyps->NAME so it can be used in yypush_parse. - (yyparse or yypush_parse): For yyparse in pull mode, replace local - parser state variable declarations with - b4_declare_parser_state_variables. - Don't initialize parser state variables when calling yypush_parse since - yypstate_new already does that. - Invoke the user's initial action only upon the first yypush_parse - invocation. - Remove all code that copies between the local parser state variables - and the yypstate. - -2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> - - * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to - prevent a name collision in a future patch where these names will - sometimes be #define'd. - (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field - since it no longer has the same name as the existing argument. - (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE. - -2006-12-19 Paolo Bonzini <bonzini@gnu.org> - and Joel E.

Discussed at - <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>. - * NEWS (2.3+): Add %symbol-default to example. - * bison.texinfo (Freeing Discarded Symbols): Likewise. - (Table of Symbols): Add entry for %symbol-default. - * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token. - (generic_symlist, generic_symlist_item): New nonterminals for creating - a list in which each item is a symbol, semantic type, or - %symbol-default. - (grammar_declaration): Use generic_symlist in %destructor and %printer - declarations instead of symbols.1 or an empty list. - (symbol_declaration, precedence_declaration, symbols.1): Update actions - for changes to symbol_list. - * src/reader.c: Update for changes to symbol_list. - * src/scan-code.l: Likewise. - * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token. - * src/symlist.c, src/symlist.h: Extend such that a list node may - represent a semantic type or a %symbol-default in addition to just an - ordinary symbol. Add switched functions for setting %destructor's and - %printer's. - * tests/actions.at, tests/input.at: Add %symbol-default to all default - %destructor/%printer declarations. - -2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu> - - Whether the default %destructor/%printer applies to a particular symbol - isn't a question of whether the user *declares* that symbol (in %token, - for example). It's a question of whether the user by any means - *defines* the symbol at all (by simply using a char token, for - example). $end is defined by Bison whereas any other token with token - number 0 is defined by the user. The error token is always defined by - Bison regardless of whether the user declares it with %token, but we - may one day let the user define error as a nonterminal instead. - * NEWS (2.3+): Say "user-defined" instead of "user-declared". - * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document - the meaning of "user-defined". - * tests/actions.at (Default %printer and %destructor for user-declared - end token): Rename to... - (Default %printer and %destructor for user-defined end token): ... - this. - - * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the - computation of whether to apply the default, don't maintain a list of - every Bison-defined symbol. Instead, just check for a first character - of '$', which a user symbol cannot have, and check for the error token. - -2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu> - - Don't apply the default %destructor or %printer to the error token, - $undefined, or $accept. This change fits the general rule that the - default %destructor and %printer are only for user-declared symbols, - and it solves several difficulties that are described in the new test - cases listed below. - * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement. - * tests/actions.at (Default %printer and %destructor are not for error - or $undefined, Default %printer and %destructor are not for $accept): - New test cases. - -2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu> - - Allow %start after the first rule. - * src/reader.c (grammar_current_rule_begin): Don't set the start symbol - when parsing the first rule. - (check_and_convert_grammar): Search for it here after all grammar - declarations have been parsed.

Denny <jdenny@ces.clemson.edu> - - Redo some of the previous commit: add back the ability to use - non-aliased/undeclared string literals since it might be useful to - those declaring %token-table. - * src/reader.c (check_and_convert_grammar): Undo changes in previous - commit: don't worry about complaints from symbols_pack. - * src/symtab.c (symbol_new, symbol_class_set, - symbol_check_alias_consistency): Undo changes in previous commit: count - each string literal as a new symbol and token, assign it a symbol - number, and don't complain about non-aliased string literals. - (symbols_pack): Since symbol_make_alias still does not decrement symbol - and token counts but does still set aliased tokens to the same number, - symbol_pack_processor now leaves empty slots in the symbols array. - Remove those slots. - * tests/regression.at (Undeclared string literal): Remove test case - added in previous commit since non-aliased string literals are allowed - again. - (Characters Escapes, Web2c Actions): Undo changes in previous commit: - remove unnecessary string literal declarations. - * tests/sets.at (Firsts): Likewise. - -2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu> - - Don't allow an undeclared string literal, but allow a string literal to - be used before its declaration. - * src/reader.c (check_and_convert_grammar): Don't invoke packgram if - symbols_pack complained. - * src/symtab.c (symbol_new): Don't count a string literal as a new - symbol. - (symbol_class_set): Don't count a string literal as a new token, and - don't assign it a symbol number since symbol_make_alias does that. - (symbol_make_alias): It's not necessary to decrement the symbol and - token counts anymore. Don't assume that an alias declaration occurs - before any uses of the identifier or string, and thus don't assert that - one of them has the highest symbol number so far. - (symbol_check_alias_consistency): Complain if there's a string literal - that wasn't declared as an alias. - (symbols_pack): Bail if symbol_check_alias_consistency failed since - symbol_pack asserts that every token has been assigned a symbol number - although undeclared string literals have not. - * tests/regression.at (String alias declared after use, Undeclared - string literal): New test cases. - (Characters Escapes, Web2c Actions): Declare string literals as - aliases. - * tests/sets.at (Firsts): Likewise. - -2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu> - - In the grammar scanner, STRING_FINISH unclosed constructs and return - them to the parser in order to improve error messages. - * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER, - SC_BRACED_CODE, SC_PROLOGUE): Implement. - * tests/input.at (Unclosed constructs): New test case. - * tests/regression.at (Invalid inputs): Update now that unclosed %{ is - seen. - - * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove - unused global. - -2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu> - - Handle string aliases for character tokens correctly. - * src/symtab.c (symbol_user_token_number_set): If the token has an - alias, check and set its alias's user token number instead of its own, - which is set to indicate the alias. Previously, every occurrence of - the character token in the grammar overwrote that alias indicator with - the character code. - * tests/input.at (String aliases for character tokens): New test. - -2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu> - - * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts. - -2006-08-11 Paul Eggert <eggert@cs.ucla.edu> - - * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT, - to prevent failures when building on older platforms. - Check for autopoint failure. - Set XGETTEXT_OPTIONS to values that check for C format strings, - so that translators are warned about them (this also helps - prevent core dumps). - - * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer - function, since it simplifies our code a bit. - - * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare - rather than -W, so we don't get bogus warnings about sign comparisons. - Add -Wpointer-arith, since that warning is useful (it reports code - that does not conform to C89 and that some compilers reject). - * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change, - since it's no longer needed. - -2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu> - - Clean up scanners a bit. - * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack - definitions so gcc won't warn when obstack_for_string is unused. - * src/scan-code.l: config.h and system.h are already #include'd by - scan-code-c.c, so get rid of them here. - * src/scan-gram.l: Likewise. - * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack - definitions rather than duplicating the rest of it. - * src/scan-gram-c.c, scan-skel-c.c: #include "system.h". - -2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu> - - Suppress signed/unsigned comparison warnings for yycheck. - * data/c.m4 (b4_safest_int_type): New macro. - * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against - a signed int type, cast it to b4_safest_int_type first. - * data/yacc.c: Likewise. - (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is - also overwritten. - -2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change) - - * doc/bison.texinfo: Fix some typos. - -2006-08-02 Paul Eggert <eggert@cs.ucla.edu> - - * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4, - po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4. - - * bootstrap (gnulib_tool): Stop using --assume-autoconf; - the latest gnulib does this a different way. - (get_translations): Sharuzzaman Ahmat Raslan reported that the ms - translation was patched, so stop omitting it. - -2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu> - - Enable declaration of default %printer/%destructor. Make the parser - use these for all user-declared grammar symbols for which the user does - not declare a specific %printer/%destructor. Thus, the parser uses it - for token 0 if the user declares it but not if Bison generates it as - $end.

This -eases our maintenance burden, (fewer merges etc.), but imposes more -requirements on anyone wishing to build from the just-checked-out sources. -For example, you have to use the latest stable versions of the maintainer -tools we depend upon, including: - -- Autoconf <http://www.gnu.org/software/autoconf/> -- Automake <http://www.gnu.org/software/automake/> -- Flex <http://www.gnu.org/software/flex/> -- Gettext <http://www.gnu.org/software/gettext/> -- Graphviz <http://www.graphviz.org> -- Gzip <http://www.gnu.org/software/gzip/> -- Perl <http://www.cpan.org/> -- Rsync <http://samba.anu.edu.au/rsync/> -- Tar <http://www.gnu.org/software/tar/> - -Valgrind <http://valgrind.org/> is also highly recommended, if it supports -your architecture. - -Bison is written using Bison grammars, so there are bootstrapping issues. -The bootstrap script attempts to discover when the C code generated from the -grammars is out of date, and to bootstrap with an out-of-date version of the -C code, but the process is not foolproof. Also, you may run into similar -problems yourself if you modify Bison. - -Only building the initial full source tree will be a bit painful. Later, -after synchronizing from the repository a plain 'make' should be sufficient. -Note, however, that when gnulib is updated, running './bootstrap' again -might be needed. - -** First checkout - -Obviously, if you are reading these notes, you did manage to check out -this package from the repository. For the record, you will find all the -relevant information on: - - http://savannah.gnu.org/git/?group=bison - -Bison uses Git submodules: subscriptions to other Git repositories. -In particular it uses gnulib, the GNU portability library. To ask Git -to perform the first checkout of the submodules, run - - $ git submodule update --init - -Git submodule support is weak before versions 1.6 and later, you -should probably upgrade Git if your version is older. - -The next step is to get other files needed to build, which are -extracted from other source packages: - - $ ./bootstrap - -And there you are! Just - - $ ./configure - $ make - $ make check - -At this point, there should be no difference between your local copy, -and the master copy: - - $ git diff - -should output no difference. - -Enjoy! - -** Updating - -The use of submodules make things somewhat different because git does -not support recursive operations: submodules must be taken care of -explicitly by the user. - -*** Updating Bison - -If you pull a newer version of a branch, say via "git pull", you might -import requests for updated submodules. A simple "git diff" will -reveal if the current version of the submodule (i.e., the actual -contents of the gnulib directory) and the current request from the -subscriber (i.e., the reference of the version of gnulib that the -Bison repository requests) differ. To upgrade the submodules (i.e., -to check out the version that is actually requested by the subscriber, -run "git submodule update". - - $ git pull - $ git submodule update - -*** Updating a submodule -To update a submodule, say gnulib, do as follows: - -Get the most recent version of the master branch from git. - - $ cd gnulib - $ git fetch - $ git checkout -b master --track origin/master - -Make sure Bison can live with that version of gnulib. - - $ cd .. - $ ./bootstrap - $ make distcheck - -Register your changes. - - $ git checkin ... - -For a suggestion of what gnulib commit might be stable enough for a -formal release, see the ChangeLog in the latest gnulib snapshot at: - - http://erislabs.net/ianb/projects/gnulib/ - -The Autoconf files we use are currently: - - m4/m4.m4 - lib/m4sugar/m4sugar.m4 - lib/m4sugar/foreach.m4 - -These files don't change very often in Autoconf, so it should be -relatively straight-forward to examine the differences in order to -decide whether to update. - -* Test suite - -** make check -Use liberally. - -** TESTSUITEFLAGS - -The default is for make check to run all tests sequentially. This can be -very time consumming when checking repeatedly or on slower setups. This can -be sped up in two ways: - -Using -j, in a make-like fashion, for example: - $ make check TESTSUITEFLAGS='-j8' - -Running only the tests of a certain category, as specified in the AT files -with AT_KEYWORDS([[category]]). Categories include: - - c++, for c++ parsers - - deprec, for tests concerning deprecated constructs. - - glr, for glr parsers - - java, for java parsers - - report, for automaton dumps - -To run a specific set of tests, use -k (for "keyword"). For example: - $ make check TESTSUITEFLAGS='-k c++' - -Both can be combined. - -** Typical errors -If the test suite shows failures such as the following one - - .../bison/lib/getopt.h:196:8: error: redefinition of 'struct option' - /usr/include/getopt.h:54:8: error: previous definition of 'struct option' - -it probably means that some file was compiled without -AT_DATA_SOURCE_PROLOGUE. This error is due to the fact that our -I options -pick up gnulib's replacement headers, such as getopt.h, and this will go -wrong if config.h was not included first. - -See tests/local.at for details. - -** make maintainer-check-valgrind -This target uses valgrind both to check bison, and the generated parsers. - -This is not mature on Mac OS X. First, Valgrind does support the way bison -calls m4, so Valgrind cannot be used to check bison on Mac OS X. - -Second, there are many errors that come from the platform itself, not from -bison. build-aux/darwin11.4.0.valgrind addresses some of them. - -Third, valgrind issues warnings such as: - - --99312:0:syswrap- WARNING: Ignoring sigreturn( ..., UC_RESET_ALT_STACK ); - -which cause the test to fail uselessly. It is hard to ignore these errors -with a major overhaul of the way instrumentation is performed in the test -suite. So currently, do not try to run valgrind on Mac OS X. - -** Release checks -Try to run the test suite with more severe conditions before a -release: - -- Configure the package with --enable-gcc-warnings, so that one checks - that 1. Bison compiles cleanly, 2. the parsers it produces compile - cleanly too. - -- Maybe build with -DGNULIB_POSIXCHECK, which suggests gnulib modules - that can fix portability issues. See if you really want to pay - attention to its warnings; there's no need to obey blindly to it - (<http://lists.gnu.org/archive/html/bison-patches/2012-05/msg00057.html>). - -- Check with "make syntax-check" if there are issues diagnosed by - gnulib. - -- run "make maintainer-check" which: - - runs "valgrind -q bison" to run Bison under Valgrind. - - runs the parsers under Valgrind. - - runs the test suite with G++ as C compiler... - -- run "make maintainer-push-check", which runs "make maintainer-check" - while activating the push implementation and its pull interface wrappers - in many test cases that were originally written to exercise only the - pull implementation. This makes certain the push implementation can - perform every task the pull implementation can. - -- run "make maintainer-xml-check", which runs "make maintainer-check" - while checking Bison's XML automaton report for every working grammar - passed to Bison in the test suite. The check just diffs the output of - Bison's included XSLT style sheets with the output of --report=all and - --graph. - -- running "make maintainer-release-check" takes care of running - maintainer-check, maintainer-push-check and maintainer-xml-check. - -- Change tests/atlocal/CFLAGS to add your preferred options. For - instance, "-traditional" to check that the parsers are K&R. Note - that it does not make sense for glr.c, which should be ANSI, but - currently is actually GNU C, nor for lalr1.cc. - -- Test with a very recent version of GCC for both C and C++. Testing - with older versions that are still in use is nice too. - - -* Release Procedure -This section needs to be updated to take into account features from -gnulib. In particular, be sure to read README-release. - -** Update the submodules. See above. - -** Update maintainer tools, such as Autoconf. See above. - -** Try to get the *.pot files to the Translation Project at least one -week before a stable release, to give them time to translate them. -Before generating the *.pot files, make sure that po/POTFILES.in and -runtime-po/POTFILES.in list all files with translatable strings. -This helps: grep -l '\<_(' * - -** Tests -See above. - -** Update the foreign files -Running "./bootstrap" in the top level should update them all for you. -This covers PO files too. Sometimes a PO file contains problems that -causes it to be rejected by recent Gettext releases; please report -these to the Translation Project. - -** Update README -Make sure the information in README is current. Most notably, make sure -it recommends a version of GNU M4 that is compatible with the latest -Bison sources. - -** Check copyright years. -We update years in copyright statements throughout Bison once at the -start of every year by running "make update-copyright". However, before -a release, it's good to verify that it's actually been run. Besides the -copyright statement for each Bison file, check the copyright statements -that the skeletons insert into generated parsers, and check all -occurrences of PACKAGE_COPYRIGHT_YEAR in configure.ac. - -** Update NEWS, commit and tag. -See do-release-commit-and-tag in README-release. For a while, we used -beta names such as "2.6_rc1". Now that we use gnulib in the release -procedure, we must use "2.5.90", which has the additional benefit of -being properly sorted in "git tag -l". - -** make alpha, beta, or stable -See README-release. - -** Upload -There are two ways to upload the tarballs to the GNU servers: using -gnupload (from gnulib), or by hand. Obviously prefer the former. But -in either case, be sure to read the following paragraph. - -*** Setup -You need "gnupg". - -Make sure your public key has been uploaded at least to -keys.gnupg.net. You can upload it with: - - gpg --keyserver keys.gnupg.net --send-keys F125BDF3 - -where F125BDF3 should be replaced with your key ID. - -*** Using gnupload -You need "ncftp". - -At the end "make stable" (or alpha/beta) will display the procedure to -run. Just copy and paste it in your shell. - -*** By hand - -The generic GNU upload procedure is at: - - http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads - -Follow the instructions there to register your information so you're permitted -to upload. - -Here's a brief reminder of how to roll the tarballs and upload them: - -*** make distcheck -*** gpg -b bison-2.3b.tar.gz -*** In a file named "bison-2.3b.tar.gz.directive", type: - - version: 1.1 - directory: bison - filename: bison-2.3b.tar.gz - -*** gpg --clearsign bison-2.3b.tar.gz.directive -*** ftp ftp-upload.gnu.org # Log in as anonymous. -*** cd /incoming/alpha # cd /incoming/ftp for full release. -*** put bison-2.3b.tar.gz # This can take a while. -*** put bison-2.3b.tar.gz.sig -*** put bison-2.3b.tar.gz.directive.asc -*** Repeat all these steps for bison-2.3b.tar.xz. - -** Update Bison manual on www.gnu.org. - -*** You need a non-anonymous checkout of the web pages directory. - - $ cvs -d YOUR_USERID@cvs.savannah.gnu.org:/web/bison checkout bison - -*** Get familiar with the instructions for web page maintainers. -http://www.gnu.org/server/standards/readme_index.html -http://www.gnu.org/server/standards/README.software.html -especially the note about symlinks. - -*** Build the web pages. -Assuming BISON_CHECKOUT refers to a checkout of the Bison dir, and -BISON_WWW_CHECKOUT refers to the web directory created above, do: - - $ cd $BISON_CHECKOUT/doc - $ make stamp-vti - $ ../build-aux/gendocs.sh -o "$BISON_WWW_CHECKOUT/manual" \ - bison "Bison - GNU parser generator" - $ cd $BISON_WWW_CHECKOUT - -Verify that the result looks sane. - -*** Commit the modified and the new files. - -*** Remove old files. -Find the files which have not been overwritten (because they belonged to -sections that have been removed or renamed): - - $ cd manual/html_node - $ ls -lt - -Remove these files and commit their removal to CVS. For each of these -files, add a line to the file .symlinks. This will ensure that -hyperlinks to the removed files will redirect to the entire manual; this -is better than a 404 error. - -There is a problem with 'index.html' being written twice (once for POSIX -function 'index', once for the table of contents); you can ignore this -issue. - -** Announce -The "make stable" (or alpha/beta) command just created a template, -$HOME/announce-bison-X.Y. Otherwise, to generate it, run: - - make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement - -where alpha can be replaced by beta or stable and F125BDF3 should be -replaced with your key ID. - -Complete/fix the announcement file. The generated list of recipients -(info-gnu@gnu.org, bug-bison@gnu.org, help-bison@gnu.org, -bison-patches@gnu.org, and coordinator@translationproject.org) is -appropriate for a stable release or a "serious beta".
