16 | * 0.2.4 |
17 | ** Language: | |
18 | - scripts now have names and can declare metavariables that are seen by | |
19 | SmPL as identifier metavariables, see demos/{python,ocaml}tococci.cocci | |
20 | - declaration (match variable declarations) and field (match structure | |
21 | field declarations) metavariables | |
c491d8ee | 22 | - matching of array initializations and of enum declarations |
413ffc02 C |
23 | |
24 | ** Features: | |
25 | - compatability with Python 2.7. Thanks to Richard W.M. Jones for pointing | |

32 | - spatch returns -1 when a virtual rule is requested that is not supported |
33 | - no transformation when using * with the option -no_show_diff | |
e6509c05 C |

5636bb2c C |
62 | * 0.2.3 |
63 | ** Language: | |
64 | - <= constraints relating an expression metavariable to one or more | |
65 | inherited expression metavariables that it should be a subexpression of | |
66 | - the -inplace and -outplace options have been renamed -in_place and | |
67 | -out_place. -in_place no longer makes a backup. A backup can be | |
68 | requested using the option -backup_suffix, eg -backup_suffix .bk | |
69 | - identifiers can be constrained to be different from an inherited | |
70 | identifier metavariable, or from a set containing both concrete | |
71 | identifiers and inherited identifier metavariables. | |

82 | - 'configure' looks for some system libraries: menhirLib, sexplib, pycaml. |
83 | Not available libraries are replaced by a copy provided with the sources. | |
84 | - added static for a function goes just before what is specified in the | |
85 | semantic patch, not before any comments etc. | |
86 | - Add a new option, -ignore_unknown_options, to ease the integration | |
87 | of Coccinelle as a checker in a toolchain. | |
88 | - error in python code causes immediate abort of spatch | |
174d1640 | 89 | - use the same algorithm for collecting grep tokens as for collecting |

111 | - add space after the last comma in an added portion of an argument list | |
90aeb998 C |
112 | - SmPL nameless struct should only match a nameless struct, not a nameless |
113 | union. Thanks to Peter Tummeltshammer for pointing out the problem. | |
114 | - adjustments to storage don't modify inline as well | |
115 | - matching and transformation allowed on inline | |

161 | - allow unknown as type for array indices in SmPL | |
162 | - support matching of static annotation on functions that are both static | |
163 | and inline | |
164 | - support ENOTDIR error in Common.lfile_exists, to allow for the case where | |
165 | an include file is in a subdirectory that exists but is an ordinary file, | |
166 | not a directory. | |
167 | - better management of unbound position variables that appear in | |

ae4735db C |
175 | * 0.2.1 |
176 | ** Language: | |
177 | - Add virtual identifiers | |
178 | - Add coccilib.report and coccilib.trac Python modules | |
179 | - coccilib.org and coccilib.report are imported by default but not loaded | |
180 | in the current scope. | |
181 | ||
182 | ** Features: | |
183 | - Parse_error_msg now more helpful. New option -verbose_parsing for even | |
184 | more information. | |
185 | - Improve Python import handling. They are imported once during script | |
186 | initialization. | |
187 | ||
188 | ** Bugfix: | |

192 | ** Language: | |
193 | ||
194 | ** Features: | |
195 | - Remove duplicated code in disjunctions | |
196 | - Better error message when grep finds nothing relevant. Thanks to Joe | |
197 | Perches for the suggestion. | |
198 | - added -keep_comments option for the unparsing of the transformed code | |

202 | - hack added to accept well-formed #define after function header | |
7f004419 C |
203 | |
204 | ** Bugfix: | |
9f8e26f4 | 205 | - Proper consideration of #define macro arguments in checking for the use |
7f004419 | 206 | of metavariables and in computing the line numbers of complex terms |

7f004419 | 215 | |
951c7801 C |
216 | * 0.1.11 |
217 | ||
218 | ** Language: | |
219 | - Meta-identifier/function and constant could be filtered from SmPL by | |
220 | regular expressions using the "~=" and "!~=" operators followed by | |
221 | an OCaml regular expression (see man Str) in double quote. | |
7f004419 C |
222 | - Virtual rules, which can be referenced in depends, and set and unset |
223 | using the command-line options -D | |
224 | - ++ for multiple additions | |
951c7801 C |
225 | |
226 | ** Features: | |
951c7801 C |
227 | - coccicheck: a framework to check a series of SmPL files on a project |
228 | see scripts/coccicheck for more information | |
229 | ||
230 | ** Bugfix: | |
231 | - bind position variables to the correct starting position in the case of a | |
232 | complex statement such as an if or while. Thanks to Derek Jones for | |
233 | pointing out the problem. | |
234 | - checking for non mentioned case lines in switch should be unchecked. | |
235 | - space should be printed after sizeof when there are no parentheses around | |
236 | the argument. Thanks to Daniel Walker for pointing out the problem. | |
237 | - avoid introducing sharing in propagating ! over () in treatment of isos | |
238 | - save_excursion has to handle and rethrow exceptions | |
239 | - eliminate unnecessary consideration of CVS strings. Thanks to David | |
240 | Young for pointing out the problem. | |
241 | - completely new treatment of statement metavariables | |
951c7801 C |
242 | - better type checking for macro definitions |
243 | - drop regression testing in -parse_c | |
244 | ||
fc1ad971 C |
245 | * 0.1.10 |
246 | ||
247 | ** Language: | |
248 | - declarations allowed in switch, suggested by Derek M. Jones | |
249 | ||
250 | ** Features: | |
251 | - use interval timer for timeouts. Thanks to Derek M. Jones for the | |
252 | implementation. | |
253 | - more flexible env.sh, thanks to Derek Jones. | |
254 | - faster Python invocation | |
255 | - simplify unparsing in the sgrep case | |
256 | ||
257 | ** Bugfix: | |
258 | - for glimpse there is no point to create a pattern containing a numeric | |
259 | constant because glimpse doesn't index them | |
260 | - add spaces after commas in function calls and function headers | |
261 | - made python integration more like the ubuntu version | |
262 | http://patches.ubuntu.com/by-release/extracted/debian/c/coccinelle/0.1.5dbs-2/01-system-pycaml | |
263 | this fixes some memory management problems with None, True, and False | |
264 | - correct labels associated with a switch in the CFG so that a statement | |
265 | metavariable can match a switch. Thanks to Derek Jones for pointing out | |
266 | the problem. | |
267 | - keep switch pattern within switch body. Thanks to Derek Jones for | |
268 | pointing out the problem. | |
269 | - Allow expanded tokens to be stored in metavariables, as long as they are | |
270 | not removed. But this does currently allow them in + code, which will | |
271 | produce the expansion. Thanks to Ali-Erdem Ozcan for pointing out the | |
272 | problem. | |
273 | - improved adjustment of spacing when code removed at the beginning of a line | |
274 | ||
978fd7e5 C |
275 | * 0.1.9 |
276 | ||
277 | ** Language: | |
278 | - allow fresh identifiers to be declared using ## such that the value mixes | |
279 | both strings and previously declared metavariables | |
280 | ||
281 | ** Features: | |
282 | - better handling of expanded code containing ##. Now compute the | |
283 | result. | |
284 | - more precise warning message for the "'\' outside define". | |
285 | Thanks to Nicholas Mc Guire for pointing out the problem. | |
286 | - more precise warning message related to ifdefization. | |
287 | Thanks to Derek Jones for pointing out the problem. | |
288 | - we don't create any more certain files in /tmp (they may be a cause | |
289 | of security problems). | |
290 | Thanks to Eugeniy Meshcheryakov for pointing out the problem. | |
291 | - More optimization for the case of just deleting a complete function. | |
292 | Allows this to happen without tracing through all the control-flow | |
293 | paths. Thanks to Francois Bissyande for pointing out the problem. | |
294 | - prevent code from being added to the beginning or end of a disjunction | |
295 | - more information about why a script is not applied when using -debug option | |
296 | - added -no_safe_expressions option | |
297 | - added -no_loops option. Ignores back edges derived from looping | |
298 | constructs. This is unsafe, but perhaps useful for bug finding, as it can | |
299 | be more efficient. | |
300 | - for semantic matches, allow "minus" on same code with multiple | |
301 | environments | |
302 | - better error message for mismatch of parenthesis in column 0 with normal | |
303 | parenthesis. Thanks to Derek Jones for pointing out the problem. | |
304 | - allow disjunctions on function return types. Thanks to Pierre Habouzit | |
305 | for pointing this out. | |
306 | ||
307 | ** Bugfix: | |
308 | - keep disjunction in the proper order for structure initialization fields | |
309 | - variables declared in different places should not seem to match each | |
310 | other | |
311 | - drop complaints about label metavariables not being used | |
312 | - drop test information from the type of an expression when the expression | |
313 | is bound to a metavariable | |
314 | - nests should not extend beyond the before and after code, even if the | |
315 | before and after code matches the nest code | |
316 | - nests should extend into conditionals that end in error exit | |
317 | - take into account metavariables on "else". Thanks to Derek Jones for | |
318 | pointing out the problem. | |
319 | - print single quotes on generated character constants | |
320 | - better typedef handling in the initialisation/affectation builtin | |
321 | isomorphism, cf -test init_affect_typedef | |
322 | - support disjunction of types on variable declaration | |
002099fc C |
323 | - allow @ within strings in script code. ignore // comment lines in script |
324 | code. | |
325 | - don't drop + code placed after the transformed code | |
326 | - drop spaces produced by removing code before semicolons | |
327 | - adjusted spacing within generated code | |
328 | - less verbose -sp. Thanks to Derek Jones for pointing out the problem. | |
329 | - accept multiple type names in a SmPL typedef declaration. | |
978fd7e5 | 330 | |
708f4980 C |
331 | * 0.1.8 |
332 | ||
333 | ** Language: | |
334 | ||
335 | ** Features: | |
336 | - Metavariables now capture the cpp code contained within their definitions | |
337 | - When - fragments are separated by ... or nest boundaries in the semantic | |
338 | patch, but end up matching adjacent source code, the comments, cpp code | |
339 | and whitespace that are between them are not deleted. | |
340 | - better parsing of C: do expansion of macros only when needed when | |
341 | have actually a parse error and also leverage the definition of macros | |
342 | in the parsed file (or in a optional_standard.h file passed as a parameter). | |
343 | This should reduce the need for many hardcoded definitions in standard.h | |
344 | - new semantics for the -macro_file option, by default now expand macros | |
345 | only when necessary. To force use the -macro_file_builtins option instead. | |
346 | - a new -extract_macros command line action to help the parser. Works with | |
347 | the -macro_file option. e.g. | |
348 | $ ./spatch -extract_macros ~/linux > /tmp/alldefs.h | |
349 | $ ./spatch -macro_file /tmp/alldefs.h -sp_file foo.cocci -dir ~/linux | |
350 | - removed -D macro_file option, not consistent with what -D usually means | |
351 | - reattempt to be more efficient for statement metavariables that are just | |
352 | placeholders (ie, no modification, no reuse) | |
353 | - triples now returned from ctl in sorted order. The main key is the | |
354 | state. On the other hand, the state order does not always agree with the | |
355 | order of appearance in the code. | |
356 | - spatch is now less verbose on the things it does yet handle. Less confusing | |
357 | for new users. | |
358 | - slightly better error report. Thanks to Derek Jones for the suggestion. | |
359 | - added the options -linux_spacing and -smpl_spacing. -linux_spacing | |
360 | causes spatch to follow the spacing conventions of Linux, while | |
361 | -smpl_spacing causes spatch to follow the spacing in the semantic patch. | |
362 | -linux_spacing is the default. | |
363 | - more informative error reporting for the already tagged token case. | |
364 | Thanks to Erik Hovland for the suggestion. | |
365 | ||
366 | ** Bugfix: | |
367 | - better parsing of declare macro at toplevel and in structure. | |
368 | cf -text xfield | |
369 | - allowing back typedef names for fieldname | |
370 | - better printing of else in generated code | |
371 | - slightly better type inference for binary operators. | |
372 | - clear out declarer names and iterator names between SmPL files (for | |
373 | -testall) | |
374 | - better parsing and type checking of macro type aliases. Cf -test macro_int16. | |
375 | Thanks to Li Yingtong for pointing out the problem. | |
376 | - make insert_virtual_positions tail rec, avoid stack overflow pb. | |
377 | Thanks to Diego Liziero <diegoliz@gmail.com> for pointing out the | |
378 | problem. | |
379 | - Better type inference for arithmetic binary operators | |
380 | Thanks to Li Yingtong for pointing out the problem. | |
381 | - Better type inference for constants | |
382 | Thanks to Li Yingtong for pointing out the problem. | |
383 | - move computing of adjacency information for semantic patches to after | |
384 | application of isomorphisms, because isomorphisms can introduce "..." | |
385 | - compute adjacency information for negated ... | |
386 | - record with each transformation site the set of indices of the witness | |
387 | trees that caused the transformation site to come about. Whitespace and | |
388 | comments between remove tokens associated with disjoint witness trees is | |
389 | not removed. | |
390 | - correct treatment of function pointer typed parameters in the SmPL ast0 | |
391 | visitor. | |
392 | - better parsing error message and error recovery when comments are not ended, | |
393 | when some macros have a weird body, and when some switch have a weird | |
394 | Body. | |
395 | Thanks to Derek Jones for pointing out the problem. | |
396 | - better detection and passing of "dangerous" ifdefs, cf -test | |
397 | double_switch. | |
398 | - dropped the separation of decls and body in Seq. This gives better | |
399 | positioning of the bindings of metavariables shared between them. | |
400 | Thanks to Erik Hovland for an example that shows the problem. | |
401 | ||
402 | ** Internals: | |
403 | - supress warning in compiling ocamlsexp (warning caused by a new behavior | |
404 | of cpp used internally in processing files in ocamlsexp/) | |
405 | ||
b1b2de81 C |
406 | * 0.1.7 |
407 | ||
408 | ** Language: | |
409 | - initialize and finalize script code, cf demos/initial_final.cocci | |
410 | ||
411 | ** Features: | |
412 | - -iso_limit option to limit the depth of isomorphism application | |
413 | - with the dir option, the include path is implicitly set to the "include" | |
414 | subdirectory of the specified directory, if the option -I is not used. | |
415 | - give a seed for the name of a fresh identifier | |
416 | - better handling of cpp "constructed" identifiers as in a##b, that in | |
417 | the futur will make it easier to match over those idents. | |
418 | cf tests/pb_parsing_macro.c. Thanks to Ali-Erdem Ozcan for pointing | |
419 | out the problem. A new "parsing hack hint" is also available: | |
420 | YACFE_IDENT_BUILDER, cf standard.h. | |
421 | ||
422 | ** Bugfix: | |
423 | - drop excessive "optimization" in ctl generation for while and for loops | |
424 | - allow . as the name of the directory | |
425 | - for type inference for an assignment, take the type of the right-hand | |
426 | side expression, not the type of the assigned variable | |
427 | - allow for with a declartion in the first header element, as in C++ | |
428 | (partial support) | |
429 | - allow for matching against variable declarations that include only | |
430 | storage, eg static, but no type at all. | |
431 | - allow for matching against types that contain both short/long and int | |
432 | - allow the type metavariable in the SmPL code "unsigned T" to match a T | |
433 | that is a type consisting of more than one word, eg long int. | |
434 | - -ifdef_to_if option made to process nested ifdefs | |
435 | (partial support) | |
436 | ||
437 | ** Internals: | |
438 | - improve and fix installation process (usable on BSD) | |
439 | - improve and fix testing process | |
440 | - apply patches from Eugeniy Meshcheryakov | |
441 | - reorganize the way we parse C identifiers, especially concatenated cpp | |
442 | identifiers as in a##b. This may lead to some regressions as we may | |
443 | not parse as much code as before. | |
444 | - removed popl/ and popl09/ and popl related stuff from official distrib. | |

457 | Thanks to Flavien@lebarbe.net for the idea. | |
0708f913 C |
458 | - the ability to print the values of more (but not all) kinds of |
459 | metavariables from python | |
460 | - new vim SmPL mode. | |
461 | Thanks to Alexander Faroy. | |
462 | ||
463 | ** Bugfix: | |
464 | - consider the ident tokens also in the 2 lines before the error line for the | |
465 | 10-most-problematic-parsing-errors diagnostic. | |
466 | - SmPL parser allows cast as the argument of a pointer | |
467 | - SmPL type checker allows enum as an array index | |
468 | - Better generation of fresh metavariables names in hrule | |
469 | - no more warnings about things that should be metavariables when there is | |
470 | a disjunction in a function position | |
471 | - bugfix in parser, better error message. | |

485 | of a block, and then is followed by a blank line | |
486 | - slightly less verbose error reporting in parsing_hacks | |
487 | ||
488 | ** Bugfix: | |
489 | - fixed some problems with parsing SmPL code where a nest appears after a | | |
490 | - better treatment of { }, form in macros wrt unparse_c | |
491 | - less quiet for -parse_c | |

faf9a90c C |
504 | ** Features: |
505 | - can match patterns of the form unsigned T or signed T, where T is a | |
506 | metavariable | |
507 | - dropped the sizeof_parens isomorphism, which was made redundant by the | |
508 | paren isomorphism | |
509 | - simple rule generation | |
faf9a90c C |
510 | |
511 | ** Bugfix: | |
512 | - trailing , ; and ) no longer left on a line by themselves | |
513 | - better treatment of error exit when the searched for code matches the | |
514 | error exit condition. | |
515 | - fix incorrect treatment of parentheses in test_exps that could allow + | |
516 | code to be added twice | |
517 | - don't ask whether iterator names and declarer names should be declared as | |
518 | metavariables. | |
519 | - slightly better support for expression list metavariables. | |
520 | - short and long allowed for array index types in SmPL | |
521 | - more restrictions on type inference for pointer arithmetic in SmPL | |
522 | - allow isomorphisms to apply when + code is anywhere within all - terms | |

527 | ||
528 | ** Internals: | |
529 | - isomorphisms don't apply under signed/unsigned, to prevent the creation | |
530 | of things like unsigned signed int. Need a better solution for this. | |
