399 | - More optimization for the case of just deleting a complete function. | |
400 | Allows this to happen without tracing through all the control-flow | |
401 | paths. Thanks to Francois Bissyande for pointing out the problem. | |
402 | - prevent code from being added to the beginning or end of a disjunction | |
403 | - more information about why a script is not applied when using -debug option | |
404 | - added -no_safe_expressions option | |
405 | - added -no_loops option. Ignores back edges derived from looping | |
406 | constructs. This is unsafe, but perhaps useful for bug finding, as it can | |
407 | be more efficient. | |
408 | - for semantic matches, allow "minus" on same code with multiple | |
409 | environments | |
410 | - better error message for mismatch of parenthesis in column 0 with normal | |
411 | parenthesis. Thanks to Derek Jones for pointing out the problem. | |
412 | - allow disjunctions on function return types. Thanks to Pierre Habouzit | |
413 | for pointing this out. | |
414 | ||
415 | ** Bugfix: | |
416 | - keep disjunction in the proper order for structure initialization fields | |
417 | - variables declared in different places should not seem to match each | |
418 | other | |
419 | - drop complaints about label metavariables not being used | |
420 | - drop test information from the type of an expression when the expression | |
421 | is bound to a metavariable | |
422 | - nests should not extend beyond the before and after code, even if the | |
423 | before and after code matches the nest code | |
424 | - nests should extend into conditionals that end in error exit | |
425 | - take into account metavariables on "else". Thanks to Derek Jones for | |
426 | pointing out the problem. | |
427 | - print single quotes on generated character constants | |
428 | - better typedef handling in the initialisation/affectation builtin | |
429 | isomorphism, cf -test init_affect_typedef | |
430 | - support disjunction of types on variable declaration | |
002099fc C |
431 | - allow @ within strings in script code. ignore // comment lines in script |
432 | code. | |
433 | - don't drop + code placed after the transformed code | |
434 | - drop spaces produced by removing code before semicolons | |
435 | - adjusted spacing within generated code | |
436 | - less verbose -sp. Thanks to Derek Jones for pointing out the problem. | |
437 | - accept multiple type names in a SmPL typedef declaration. | |

439 | * 0.1.8 |
440 | ||
441 | ** Language: | |
442 | ||
443 | ** Features: | |
444 | - Metavariables now capture the cpp code contained within their definitions | |
445 | - When - fragments are separated by ... or nest boundaries in the semantic | |
446 | patch, but end up matching adjacent source code, the comments, cpp code | |
447 | and whitespace that are between them are not deleted. | |
448 | - better parsing of C: do expansion of macros only when needed when | |
449 | have actually a parse error and also leverage the definition of macros | |
450 | in the parsed file (or in a optional_standard.h file passed as a parameter). | |
451 | This should reduce the need for many hardcoded definitions in standard.h | |
452 | - new semantics for the -macro_file option, by default now expand macros | |
453 | only when necessary. To force use the -macro_file_builtins option instead. | |
454 | - a new -extract_macros command line action to help the parser. Works with | |
455 | the -macro_file option. e.g. | |
456 | $ ./spatch -extract_macros ~/linux > /tmp/alldefs.h | |
457 | $ ./spatch -macro_file /tmp/alldefs.h -sp_file foo.cocci -dir ~/linux | |
458 | - removed -D macro_file option, not consistent with what -D usually means | |
459 | - reattempt to be more efficient for statement metavariables that are just | |
460 | placeholders (ie, no modification, no reuse) | |
461 | - triples now returned from ctl in sorted order. The main key is the | |
462 | state. On the other hand, the state order does not always agree with the | |
463 | order of appearance in the code. | |
464 | - spatch is now less verbose on the things it does yet handle. Less confusing | |
465 | for new users. | |
466 | - slightly better error report. Thanks to Derek Jones for the suggestion. | |
467 | - added the options -linux_spacing and -smpl_spacing. -linux_spacing | |
468 | causes spatch to follow the spacing conventions of Linux, while | |
469 | -smpl_spacing causes spatch to follow the spacing in the semantic patch. | |
470 | -linux_spacing is the default. | |
471 | - more informative error reporting for the already tagged token case. | |
472 | Thanks to Erik Hovland for the suggestion. | |
473 | ||
474 | ** Bugfix: | |
475 | - better parsing of declare macro at toplevel and in structure. | |
476 | cf -text xfield | |
477 | - allowing back typedef names for fieldname | |
478 | - better printing of else in generated code | |
479 | - slightly better type inference for binary operators. | |
480 | - clear out declarer names and iterator names between SmPL files (for | |
481 | -testall) | |
482 | - better parsing and type checking of macro type aliases. Cf -test macro_int16. | |
483 | Thanks to Li Yingtong for pointing out the problem. | |
484 | - make insert_virtual_positions tail rec, avoid stack overflow pb. | |
485 | Thanks to Diego Liziero <diegoliz@gmail.com> for pointing out the | |
486 | problem. | |
487 | - Better type inference for arithmetic binary operators | |
488 | Thanks to Li Yingtong for pointing out the problem. | |
489 | - Better type inference for constants | |
490 | Thanks to Li Yingtong for pointing out the problem. | |
491 | - move computing of adjacency information for semantic patches to after | |
492 | application of isomorphisms, because isomorphisms can introduce "..." | |
493 | - compute adjacency information for negated ... | |
494 | - record with each transformation site the set of indices of the witness | |
495 | trees that caused the transformation site to come about. Whitespace and | |
496 | comments between remove tokens associated with disjoint witness trees is | |
497 | not removed. | |
498 | - correct treatment of function pointer typed parameters in the SmPL ast0 | |
499 | visitor. | |
500 | - better parsing error message and error recovery when comments are not ended, | |
501 | when some macros have a weird body, and when some switch have a weird | |
502 | Body. | |
503 | Thanks to Derek Jones for pointing out the problem. | |
504 | - better detection and passing of "dangerous" ifdefs, cf -test | |
505 | double_switch. | |
506 | - dropped the separation of decls and body in Seq. This gives better | |
507 | positioning of the bindings of metavariables shared between them. | |
508 | Thanks to Erik Hovland for an example that shows the problem. | |

522 | subdirectory of the specified directory, if the option -I is not used. | |
523 | - give a seed for the name of a fresh identifier | |
524 | - better handling of cpp "constructed" identifiers as in a##b, that in | |
525 | the futur will make it easier to match over those idents. | |
526 | cf tests/pb_parsing_macro.c. Thanks to Ali-Erdem Ozcan for pointing | |
527 | out the problem. A new "parsing hack hint" is also available: | |
528 | YACFE_IDENT_BUILDER, cf standard.h. | |
529 | ||
530 | ** Bugfix: | |
531 | - drop excessive "optimization" in ctl generation for while and for loops | |
532 | - allow . as the name of the directory | |
533 | - for type inference for an assignment, take the type of the right-hand | |
534 | side expression, not the type of the assigned variable | |
535 | - allow for with a declartion in the first header element, as in C++ | |
536 | (partial support) | |
537 | - allow for matching against variable declarations that include only | |
538 | storage, eg static, but no type at all. | |
539 | - allow for matching against types that contain both short/long and int | |
540 | - allow the type metavariable in the SmPL code "unsigned T" to match a T | |
541 | that is a type consisting of more than one word, eg long int. | |
542 | - -ifdef_to_if option made to process nested ifdefs | |
543 | (partial support) | |

545 | ** Internals: | |
546 | - improve and fix installation process (usable on BSD) | |

548 | - apply patches from Eugeniy Meshcheryakov | |
549 | - reorganize the way we parse C identifiers, especially concatenated cpp | |
550 | identifiers as in a##b. This may lead to some regressions as we may | |
551 | not parse as much code as before. | |
552 | - removed popl/ and popl09/ and popl related stuff from official distrib. | |

572 | - consider the ident tokens also in the 2 lines before the error line for the | |
