| 28Apr 24, 2005: 29 modified lib.c so that values of $0 et al are preserved in the END 30 block, apparently as required by posix. thanks to havard eidnes 31 for the report and code. 32 33Jan 14, 2005: 34 fixed infinite loop in parsing, originally found by brian tsang. 35 thanks to arnold robbins for a suggestion that started me 36 rethinking it. 37 38Dec 31, 2004: 39 prevent overflow of -f array in main, head off potential error in 40 call of SYNTAX(), test malloc return in lib.c, all with thanks to 41 todd miller. 42 43Dec 22, 2004: 44 cranked up size of NCHARS; coverity thinks it can be overrun with 45 smaller size, and i think that's right. added some assertions to b.c 46 to catch places where it might overrun. the RE code is still fragile. 47 48Dec 5, 2004: 49 fixed a couple of overflow problems with ridiculous field numbers: 50 e.g., print $(2^32-1). thanks to ruslan ermilov, giorgos keramidas 51 and david o'brien at freebsd.org for patches. this really should 52 be re-done from scratch. 53 54Nov 21, 2004: 55 fixed another 25-year-old RE bug, in split. it's another failure 56 to (re-)initialize. thanks to steve fisher for spotting this and 57 providing a good test case. 58 |

| 28Nov 22, 2003: 29 fixed a bug in regular expressions that dates (so help me) from 1977; 30 it's been there from the beginning. an anchored longest match that 31 was longer than the number of states triggered a failure to initialize 32 the machine properly. many thanks to moinak ghosh for not only finding 33 this one but for providing a fix, in some of the most mysterious 34 code known to man. 35 --- 181 unchanged lines hidden (view full) --- 217 Santiago Vila <sanvila@unex.es> for the bug report. 218 219Apr 21, 2000: 220 finally found and fixed a memory leak in function call; it's 221 been there since functions were added ~1983. thanks to 222 jon bentley for the test case that found it. 223 224 added test in envinit to catch environment "variables" with | 59Nov 22, 2003: 60 fixed a bug in regular expressions that dates (so help me) from 1977; 61 it's been there from the beginning. an anchored longest match that 62 was longer than the number of states triggered a failure to initialize 63 the machine properly. many thanks to moinak ghosh for not only finding 64 this one but for providing a fix, in some of the most mysterious 65 code known to man. 66 --- 181 unchanged lines hidden (view full) --- 248 Santiago Vila <sanvila@unex.es> for the bug report. 249 250Apr 21, 2000: 251 finally found and fixed a memory leak in function call; it's 252 been there since functions were added ~1983. thanks to 253 jon bentley for the test case that found it. 254 255 added test in envinit to catch environment "variables" with |

| 226 227Jul 28, 1999: 228 added test in defn() to catch function foo(foo), which 229 otherwise recurses until core dump. thanks to arnold 230 robbins for noticing this. 231 232Jun 20, 1999: 233 added *bp in gettok in lex.c; appears possible to exit function --- 220 unchanged lines hidden (view full) --- 454 455 small fixes to regexpr code: can now handle []], [[], and 456 variants; [] is now a syntax error, rather than matching 457 everything; [z-a] is now empty, not z. far from complete 458 or correct, however.

| 463 usurp this name and this causes conflicts. 464 465 fixed call to time in run.c (bltin); arg is time_t *. 466 467 replaced horrible pointer/long punning in b.c by a legitimate 468 union. should be safer on 64-bit machines and cleaner everywhere. 469 (thanks to nelson beebe for pointing out some of these problems.) 470 --- 387 unchanged lines hidden --- | 494 usurp this name and this causes conflicts. 495 496 fixed call to time in run.c (bltin); arg is time_t *. 497 498 replaced horrible pointer/long punning in b.c by a legitimate 499 union. should be safer on 64-bit machines and cleaner everywhere. 500 (thanks to nelson beebe for pointing out some of these problems.) 501 --- 387 unchanged lines hidden --- |
