Original commit message from CVS: Patch by: Marc-Andre Lureau <marcandre dot lureau at gmail dot com> * gst/parse/Makefile.am: * gst/parse/grammar.y: * gst/parse/parse.l: Make the parser reentrant and recursively callable. This requires flex >= 2.5.31, for older versions pregenerated sources are used as we can't bump the build dependency. Finally fixes #349180. * gst/gstparse.c: (gst_parse_launch): Drop the HAVE_MT_SAVE_FLEX #ifdefs as we always use a new enough flex now anyway. * docs/gst/Makefile.am: * docs/gst/Makefile.am: * gst/parse/grammar.tab.pre.c: (__gst_parse_strdup), (__gst_parse_strfree), (__gst_parse_link_new), (__gst_parse_link_free), (__gst_parse_chain_new), (__gst_parse_chain_free), (SET_ERROR), (YYPRINTF), (gst_parse_element_set), (gst_parse_free_link), (gst_parse_found_pad), (gst_parse_perform_delayed_link), (gst_parse_perform_link), (yytnamerr), (yysyntax_error), (yyerror), (_gst_parse_launch): * gst/parse/grammar.tab.pre.h: * gst/parse/lex._gst_parse_yy.pre.c: (PRINT), (yy_get_next_buffer), (yy_get_previous_state), (yy_try_NUL_trans), (input), (_gst_parse_yyrestart), (_gst_parse_yy_switch_to_buffer), (_gst_parse_yy_load_buffer_state), (_gst_parse_yy_create_buffer), (_gst_parse_yy_delete_buffer), (_gst_parse_yy_init_buffer), (_gst_parse_yy_flush_buffer), (_gst_parse_yypush_buffer_state), (_gst_parse_yypop_buffer_state), (_gst_parse_yyensure_buffer_stack), (_gst_parse_yy_scan_buffer), (_gst_parse_yy_scan_string), (_gst_parse_yy_scan_bytes), (yy_fatal_error), (_gst_parse_yyget_extra), (_gst_parse_yyget_lineno), (_gst_parse_yyget_column), (_gst_parse_yyget_in), (_gst_parse_yyget_out), (_gst_parse_yyget_leng), (_gst_parse_yyget_text), (_gst_parse_yyset_extra), (_gst_parse_yyset_lineno), (_gst_parse_yyset_column), (_gst_parse_yyset_in), (_gst_parse_yyset_out), (_gst_parse_yyget_debug), (_gst_parse_yyset_debug), (_gst_parse_yyget_lval), (_gst_parse_yyset_lval), (_gst_parse_yylex_init), (yy_init_globals), (_gst_parse_yylex_destroy), (yy_flex_strncpy), (yy_flex_strlen), (_gst_parse_yyalloc), (_gst_parse_yyrealloc), (_gst_parse_yyfree): If the installed flex version is too old use pre-generated parser sources. These pre-generated parser sources are always updated when the actual flex/bison sources change but require everybody who wants to change something in the parser to have flex >= 2.5.31 installed.
