7fe62b65 C |
38 | - gcc constructors allowed in SmPL. Thanks to Uwe Kleine-Koenig for |
39 | pointing out the problem. | |

56 | - Improve warning message when using -use_cache | |
8babbc8f C |
57 | - More helpful initial value for exported variables in python |
58 | - Support - on expression nests | |
65038c61 C |
59 | - Better handling of the case of a matched declaration that should only |

5427db06 C |
61 | - Allow a semantic patch beginning and ending with braces to match the |
62 | complete body of a function if the braces are not removed and if nothing | |
63 | is added before the first brace or after the last one. | |
64 | - Add -cache_prefix option, to specify where to put cached files. | |
65 | - Allow module_init(foo); to match module_init(foo) (or likewise for any | |
66 | declarer), when no transformation is specified on the semicolon. | |
67 | - Add Coccilib.exit() for ocaml code and cocci.exit() for python code, | |
68 | to abort the treatment of the current file. | |

83 | environments. | |
84 | - A local variable that is declared without a type is not considered to be | |
85 | a local variable. Actually, such a variable is probably really a macro | |
86 | that expends to a declaration, and this macro is not the variable name. | |
87 | - Allow iteration to make modifications when the modifications are done | |
88 | inplace. | |
89 | - -debug gives information about defined virtual rules and about virtual | |
90 | identifier bindings. | |

128 | - Don't call Insert_plus on rules that cannot be evaluated due to failed |
129 | dependencies. | |
130 | - Allow variable declaration right after a case in switch. | |
131 | - The top of a loop is also after the body of a loop, for ... in loop body | |
132 | - Do not anchor Str regexp at the beginning of the string to check | |
133 | - Type annotation for C code uses most recent env for typedefs when | |

472 | constant because glimpse doesn't index them | |
473 | - add spaces after commas in function calls and function headers | |
474 | - made python integration more like the ubuntu version | |
475 | http://patches.ubuntu.com/by-release/extracted/debian/c/coccinelle/0.1.5dbs-2/01-system-pycaml | |
476 | this fixes some memory management problems with None, True, and False | |

478 | metavariable can match a switch. Thanks to Derek Jones for pointing out | |
479 | the problem. | |
480 | - keep switch pattern within switch body. Thanks to Derek Jones for | |
481 | pointing out the problem. | |
482 | - Allow expanded tokens to be stored in metavariables, as long as they are | |

498 | Thanks to Nicholas Mc Guire for pointing out the problem. | |
499 | - more precise warning message related to ifdefization. | |
500 | Thanks to Derek Jones for pointing out the problem. | |
501 | - we don't create any more certain files in /tmp (they may be a cause | |
502 | of security problems). | |
503 | Thanks to Eugeniy Meshcheryakov for pointing out the problem. | |
504 | - More optimization for the case of just deleting a complete function. | |
505 | Allows this to happen without tracing through all the control-flow | |
506 | paths. Thanks to Francois Bissyande for pointing out the problem. | |
507 | - prevent code from being added to the beginning or end of a disjunction | |
508 | - more information about why a script is not applied when using -debug option | |
509 | - added -no_safe_expressions option | |
510 | - added -no_loops option. Ignores back edges derived from looping | |
511 | constructs. This is unsafe, but perhaps useful for bug finding, as it can | |
512 | be more efficient. | |
513 | - for semantic matches, allow "minus" on same code with multiple | |
514 | environments | |
515 | - better error message for mismatch of parenthesis in column 0 with normal | |
516 | parenthesis. Thanks to Derek Jones for pointing out the problem. | |

524 | - drop complaints about label metavariables not being used | |
525 | - drop test information from the type of an expression when the expression | |
526 | is bound to a metavariable | |
527 | - nests should not extend beyond the before and after code, even if the | |
528 | before and after code matches the nest code | |
529 | - nests should extend into conditionals that end in error exit | |
530 | - take into account metavariables on "else". Thanks to Derek Jones for | |
531 | pointing out the problem. | |
532 | - print single quotes on generated character constants | |

708f4980 C |
544 | * 0.1.8 |
545 | ||
546 | ** Language: | |
547 | ||
548 | ** Features: | |
549 | - Metavariables now capture the cpp code contained within their definitions | |
550 | - When - fragments are separated by ... or nest boundaries in the semantic | |
551 | patch, but end up matching adjacent source code, the comments, cpp code | |
552 | and whitespace that are between them are not deleted. | |
553 | - better parsing of C: do expansion of macros only when needed when | |
554 | have actually a parse error and also leverage the definition of macros | |
555 | in the parsed file (or in a optional_standard.h file passed as a parameter). | |
556 | This should reduce the need for many hardcoded definitions in standard.h | |
557 | - new semantics for the -macro_file option, by default now expand macros | |
558 | only when necessary. To force use the -macro_file_builtins option instead. | |
559 | - a new -extract_macros command line action to help the parser. Works with | |
560 | the -macro_file option. e.g. | |
561 | $ ./spatch -extract_macros ~/linux > /tmp/alldefs.h | |
562 | $ ./spatch -macro_file /tmp/alldefs.h -sp_file foo.cocci -dir ~/linux | |
563 | - removed -D macro_file option, not consistent with what -D usually means | |
564 | - reattempt to be more efficient for statement metavariables that are just | |
565 | placeholders (ie, no modification, no reuse) | |
566 | - triples now returned from ctl in sorted order. The main key is the | |
567 | state. On the other hand, the state order does not always agree with the | |
568 | order of appearance in the code. | |
569 | - spatch is now less verbose on the things it does yet handle. Less confusing | |
570 | for new users. | |
571 | - slightly better error report. Thanks to Derek Jones for the suggestion. | |
572 | - added the options -linux_spacing and -smpl_spacing. -linux_spacing | |
573 | causes spatch to follow the spacing conventions of Linux, while | |
574 | -smpl_spacing causes spatch to follow the spacing in the semantic patch. | |
575 | -linux_spacing is the default. | |
576 | - more informative error reporting for the already tagged token case. | |
577 | Thanks to Erik Hovland for the suggestion. | |
578 | ||
579 | ** Bugfix: | |
580 | - better parsing of declare macro at toplevel and in structure. | |

586 | -testall) | |
587 | - better parsing and type checking of macro type aliases. Cf -test macro_int16. | |
588 | Thanks to Li Yingtong for pointing out the problem. | |

590 | Thanks to Diego Liziero <diegoliz@gmail.com> for pointing out the | |
591 | problem. | |
592 | - Better type inference for arithmetic binary operators | |
593 | Thanks to Li Yingtong for pointing out the problem. | |
594 | - Better type inference for constants | |
595 | Thanks to Li Yingtong for pointing out the problem. | |
596 | - move computing of adjacency information for semantic patches to after | |
597 | application of isomorphisms, because isomorphisms can introduce "..." | |
598 | - compute adjacency information for negated ... | |
599 | - record with each transformation site the set of indices of the witness | |
600 | trees that caused the transformation site to come about. Whitespace and | |
601 | comments between remove tokens associated with disjoint witness trees is | |
602 | not removed. | |
603 | - correct treatment of function pointer typed parameters in the SmPL ast0 | |
604 | visitor. | |
605 | - better parsing error message and error recovery when comments are not ended, | |
606 | when some macros have a weird body, and when some switch have a weird | |
607 | Body. | |
608 | Thanks to Derek Jones for pointing out the problem. | |
609 | - better detection and passing of "dangerous" ifdefs, cf -test | |
610 | double_switch. | |
611 | - dropped the separation of decls and body in Seq. This gives better | |
612 | positioning of the bindings of metavariables shared between them. | |
613 | Thanks to Erik Hovland for an example that shows the problem. | |

634 | ||
635 | ** Bugfix: | |
636 | - drop excessive "optimization" in ctl generation for while and for loops | |
637 | - allow . as the name of the directory | |
638 | - for type inference for an assignment, take the type of the right-hand | |
639 | side expression, not the type of the assigned variable | |
640 | - allow for with a declartion in the first header element, as in C++ | |
641 | (partial support) | |
642 | - allow for matching against variable declarations that include only | |
643 | storage, eg static, but no type at all. | |
644 | - allow for matching against types that contain both short/long and int | |
645 | - allow the type metavariable in the SmPL code "unsigned T" to match a T | |
646 | that is a type consisting of more than one word, eg long int. | |
647 | - -ifdef_to_if option made to process nested ifdefs | |

655 | identifiers as in a##b. This may lead to some regressions as we may | |
656 | not parse as much code as before. | |
657 | - removed popl/ and popl09/ and popl related stuff from official distrib. | |
