|
|---|
| 14 | First, thanks to Yuri, nickk, Paul and Andy for patches, bugs and
|
|---|
| 15 | other feedback.
|

| 16 |
|
|---|
| 17 |
|

| 45 | GCC v3.3.5 / LIBC v0.6:
|
|---|
| 46 | -----------------------
|
|---|
| 47 |
|
|---|
| 48 | There was a build problem with the first attempt at releasing.
|
|---|
| 49 | This is the 2nd attempt, hope I got it right this time...
|
|---|
| 50 |
|
|---|
| 51 | WARNINGS
|
|---|
| 52 |
|
|---|
| 53 | There are several incompatible interface changes. So, you'll have
|
|---|
| 54 | to rebuild static libraries and it's a good idea to do the same
|
|---|
| 55 | thing for dynamic libs and programs too.
|
|---|
| 56 |
|
|---|
| 57 | The build is not tested as much as I would've liked. I'm very
|
|---|
| 58 | pressed on time as usual, but I really wanted to get the 0.6 stuff
|
|---|
| 59 | out now. I can only hope everything still builds and works.
|
|---|
| 60 |
|
|---|
| 61 |
|
|---|
| 62 | The Project is Moving
|
|---|
| 63 |
|
|---|
| 64 | The source code has been migrated to subversion and now resides
|
|---|
| 65 | on the svn.netlabs.org server. The server also provides an issue
|
|---|
| 66 | tracker and project management service called trac. Check it
|
|---|
| 67 | out at http://svn.netlabs.org/libc/.
|
|---|
| 68 |
|
|---|
| 69 | The source code for this release (and any bugfix releases on
|
|---|
| 70 | the 0.6 code base) can be checked out using this url:
|
|---|
| 71 | http://svn.netlabs.org/repos/libc/branches/libc-0.6
|
|---|
| 72 |
|
|---|
| 73 | Developers who wish to contribute to the 0.7 code will have to
|
|---|
| 74 | diff against the trunk. There are several pending restructuring
|
|---|
| 75 | tasks on 0.7, so don't expect everything to build fine or work
|
|---|
| 76 | properly while those are still open. Anyway, the url:
|
|---|
| 77 | http://svn.netlabs.org/repos/libc/trunk
|
|---|
| 78 |
|
|---|
| 79 | Users are encouraged to join the [email protected] mailing list
|
|---|
| 80 | and use that list for questions rather than the InnoTek form. If
|
|---|
| 81 | you think you've found a bug, you should first ask on the mailing
|
|---|
| 82 | list, and if I decide it's a *real*, *new*, bug I'll open a
|
|---|
| 83 | ticket for it and address it.
|
|---|
| 84 |
|
|---|
| 85 | Developers which have patches for real bugs or enhancements can
|
|---|
| 86 | create trac tickets and drop me or the gcc-user list a mail (we
|
|---|
| 87 | haven't figure out how to get email notifications from trac yet).
|
|---|
| 88 |
|
|---|
| 89 |
|
|---|
| 90 | New features:
|
|---|
| 91 |
|
|---|
| 92 | o Added __libc_Back_gfProcessHandlePCBatchScripts and
|
|---|
| 93 | __libc_Back_gfProcessHandleHashBangScripts (globale
|
|---|
| 94 | variables) to turn on/off script handling in exec/spawn.
|
|---|
| 95 | Very useful for shells.
|
|---|
| 96 |
|
|---|
| 97 | o Changed the default stack of emxomfld and emxbind to 1MB,
|
|---|
| 98 | it used to be 8KB and 8MB.
|
|---|
| 99 |
|
|---|
| 100 | o open() can now open directories like on unix, and fchdir()
|
|---|
| 101 | can chdir to the opened directories.
|
|---|
| 102 |
|
|---|
| 103 | o Implemented much of the unix-attributes-in EA stuff.
|
|---|
| 104 |
|
|---|
| 105 | o Implemented getdirents(), will be used to replace
|
|---|
| 106 | opendir/readdir/seekdir/telldir/closedir in 0.7.
|
|---|
| 107 |
|
|---|
| 108 | o Implemented the fcntl interface for setting and clearing
|
|---|
| 109 | the O_NONBLOCK flag on sockets.
|
|---|
| 110 |
|
|---|
| 111 |
|
|---|
| 112 | Bug fixes:
|
|---|
| 113 |

|
|---|
| 115 | Kudos to Andrew Below for spotting it.
|
|---|

|
|---|
| 117 | o Fixed ld bustage in rc1.
|
|---|
| 118 |
|
|---|
| 119 | o Fixed fork bug in shm.
|
|---|
| 120 |
|
|---|
| 121 | o Fixed spawn/exec bug where .exe was appended too early
|
|---|
| 122 | preventing configure and other scripts without suffix
|
|---|
| 123 | from being executed.
|
|---|
| 124 |
|
|---|
| 125 | o Fixed several signal bugs (deadlocks, sigsuspend, pause).
|
|---|
| 126 |
|
|---|
| 127 | o Fixed symbol truncation problem in emxomf.
|
|---|
| 128 |
|
|---|
| 129 | o Fixed a generic error handling bug in ioctl, write, read,
|
|---|
| 130 | dup and dup2 which was causing incorrect errno values.
|
|---|
| 131 |
|
|---|
| 132 |

| 232 | GCC v3.3.5 / LIBC v0.6 - Beta 5:
|
|---|
| 233 | --------------------------------
|
|---|
| 234 |
|
|---|
| 235 | Thanks to Lorne, Froloff, nickk and Andy for sending me patches,
|
|---|
| 236 | debugging problems and/or testing fixes.
|
|---|
| 237 |
|
|---|
| 238 | New features:
|
|---|
| 239 |
|
|---|
| 240 | o Added support for __declspec(dllexport), _Export
|
|---|
| 241 | and __declspec(dllimport), the latter being a stub.
|
|---|
| 242 | This also included adding N_EXP to the a.out format.
|
|---|
| 243 |
|
|---|
| 244 | o Lot's of math stuff, mostly untested.
|
|---|
| 245 |
|
|---|
| 246 | o Optimized zeroing of new file space in ftruncate and
|
|---|
| 247 | chsize with knowlegde about the filesystem. HPFS, JFS
|
|---|
| 248 | and FAT will do the zeroing for us.
|
|---|
| 249 |
|
|---|
| 250 | o Support for unlocked stdio, with both BSD and GNU
|
|---|
| 251 | extensions implemented.
|
|---|
| 252 |
|
|---|
| 253 | o Execute .cmd, .bat, .btm and hash-bang scripts.
|
|---|
| 254 |
|
|---|
| 255 | o Respect single quotes in argument handling (sed craze).
|
|---|
| 256 |
|
|---|
| 257 | o Ported fts.h and the BSD implementation.
|
|---|
| 258 |
|
|---|
| 259 | o Ported BSD sysctl. (Does not include the tcpip v4.1
|
|---|
| 260 | sysctl() bits yet.)
|
|---|
| 261 |
|
|---|
| 262 | o Ported the FreeBSD implementation of SysV semaphores
|
|---|
| 263 | and shared memory.
|
|---|
| 264 |
|
|---|
| 265 | o Env.var. LIBC_THREAD_MIN_STACK_SIZE can be used to
|
|---|
| 266 | specify the minimum stack size for new threads. The
|
|---|
| 267 | default minimum is 4096 bytes.
|
|---|
| 268 |
|
|---|
| 269 | o Ported (lib)intl from glibc.
|
|---|
| 270 |
|
|---|
| 271 | o New gcc arguments -Zargs-wild and -Zargs-resp.
|
|---|
| 272 |
|
|---|
| 273 | o New functions (might not be 100% correct):
|
|---|

|---|
| 275 | __dcngettext(), __dgettext(), __dngettext(), __gettext(),

|
|---|
| 328 | Bug fixes:
|
|---|
| 329 |
|
|---|
| 330 | o Numerous bugfixes in libc, see ChangeLog.LIBC for
|
|---|
| 331 | details.
|
|---|
| 332 |
|
|---|
| 333 | o Fixed problems with receiving signals during fork().
|
|---|
| 334 |
|
|---|
| 335 | o Fixed bug in timer backend if the system had no
|
|---|
| 336 | exiting timers. Kudos to Froloff for noticing this.
|
|---|
| 337 |
|
|---|
| 338 |
|
|---|
| 339 | Known problems:
|
|---|

| 341 | o Static linking not possible - will be fixed.
|
|---|
| 342 |
|
|---|
| 343 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 344 | This won't change.
|
|---|
| 345 |

|
|---|
| 347 | job control. They'll show up soon.
|
|---|
| 348 |
|
|---|
| 349 | o The HLL debug info isn't working 100% correctly.
|

| 362 | GCC v3.3.5 / LIBC v0.6 - Beta 4:
|
|---|
| 363 | --------------------------------
|
|---|
| 364 |
|
|---|
| 365 | Thanks to Lorne, Froloff and nickk for sending me patches,
|
|---|
| 366 | debugging problems and testing fixes.
|
|---|

| 370 | o Added st_dev and st_ino calculation for fstat and stat.
|
|---|
| 371 |
|
|---|
| 372 | o Added most of the wide string functions.
|
|---|
| 373 | N.B. the stream functions are still missing.
|
|---|
| 374 |
|
|---|
| 375 | o New functions:
|
|---|
| 376 | SafeDosStartSession(), wcscat(), wcschr(), wcscmp(),
|
|---|
| 377 | wcscoll(), wcscpy(), wcscspn(), wcslcat(), wcslcpy(),

| 386 | o Some underflow/overflow problems tested for by many
|
|---|
| 387 | Configure scripts was fixed by using a 64-bit time
|
|---|
| 388 | type internally.
|
|---|
| 389 |
|
|---|
| 390 | o fxsave/fxrstore problem in fork(). (This isn't tested
|
|---|
| 391 | because lack of (reliable) obsolete hardware.)
|
|---|
| 392 |
|
|---|
| 393 | o Fixed fork() and DosLoadModule problem in child.
|
|---|
| 394 |
|
|---|
| 395 | o nl_langinfo(CODESET) now returns something useful,
|
|---|
| 396 | adding a few ascii codeset aliases at the same time.
|
|---|
| 397 |
|
|---|
| 398 | o Bug in socket inheritance over exec/spawn.
|
|---|
| 399 |
|
|---|
| 400 | o Missing semphore and signal blocking when processing
|
|---|
| 401 | external signals.
|
|---|
| 402 |

|
|---|
| 414 |
|
|---|
| 415 | o Fixed libsocket to set errno to ENOSOCK when given a

| 416 | filehandle instead of a socket. Previous was ENOSYS.
|
|---|
| 417 |
|
|---|
| 418 | o Corrected NP_NBLK define in os2emx.h.
|
|---|
| 419 |

| 420 | o Export __mcount stub. LIBCxx.prf export non-stub.
|
|---|
| 421 |
|
|---|
| 422 | o Added missing libdl stub libraries (dlfcn is in libc
|
|---|
| 423 | as of last release).
|
|---|
| 424 |
|
|---|
| 425 | o Fixed missing WNOHANG handling in the wait functions.
|
|---|
| 426 |
|
|---|
| 427 | o Adjusted the ECHILD and EINVAL errnos usage in
|
|---|
| 428 | the wait functions to match the waitpid() spec.
|
|---|
| 429 |
|
|---|
| 430 | o ???
|
|---|
| 431 |
|
|---|
| 432 | Todos before LIBC06.DLL:
|
|---|
| 433 |
|
|---|
| 434 | 0. Fix all bugs. :-)
|
|---|
| 435 |
|
|---|
| 436 | 1. Reimplement opendir in BSD style (+fchdir).
|
|---|
| 437 |
|
|---|
| 438 | 2. Shared IPC structures for XSI msq, sem and shm.
|
|---|
| 439 |
|
|---|
| 440 | 3. Missing job pgid functions.
|
|---|
| 441 |
|
|---|
| 442 | 4. Port GLIBC intl/*. gettext is a pita! because it's
|
|---|
| 443 | passing FILE pointers around between different LIBCs.
|
|---|
| 444 | objdump is constantly broken between LIBC versions.
|
|---|
| 445 |
|
|---|
| 446 | 5. Figure out the EA exclusive read access trouble.
|
|---|
| 447 |
|
|---|
| 448 | 6. Calc ino_t on file creation and store it in EAs.

| 451 | of tcpip additions.
|
|---|
| 452 |
|
|---|
| 453 | 8. adjtime() implementation.

|
|---|
| 459 |
|
|---|
| 460 | New features:
|
|---|
| 461 |
|
|---|
| 462 | o wchar.h and wctype.h and much of the non-stream functions
|
|---|
| 463 | declared therein are implemented. Though, the FreeBSD
|
|---|
| 464 | string/w*.c functions are still in the porting queue.
|
|---|
| 465 |
|
|---|
| 466 | o Added __mcount stub to all LIBC DLLs but the .prf one which
|
|---|
| 467 | is forwarding __mcount from kProfile.dll.
|
|---|
| 468 |
|
|---|
| 469 | o DosLoadModuleEx and DosFreeModuleEx was created to support
|
|---|
| 470 | loaded modules over a fork(). dlopen/dlclose backend was
|
|---|
| 471 | changed to use these.
|
|---|
| 472 |
|
|---|
| 473 | o Fixed rand() range problem. Using the BSD code for this
|
|---|
| 474 | too, which means a new algorithm.
|
|---|
| 475 |
|
|---|
| 476 | o Update all BSD source-files (not headers) to FreeBSD 5.3
|
|---|
| 477 | level.
|
|---|
| 478 |
|
|---|
| 479 | o New functions:
|
|---|
| 480 | DosLoadModuleEx(), DosFreeModuleEx(), sranddev(),
|
|---|
| 481 | getsubopt(), rand_r(), llabs(), lldiv(), dlfunc(),
|

|
|---|
| 493 | wcsnrtombs(), wcsrtombs(), wcstod(), wcstof(),
|
|---|
| 494 | wcstoimax(), wcstol(), wcstold(), wcstoll(), wcstoul(),
|
|---|
| 495 | wcstoull(), wcstoumax(), wctob(), wctrans(), wctype(),
|
|---|
| 496 | towlower(), towupper().
|
|---|
| 497 |
|
|---|
| 498 |
|
|---|
| 499 | Bug fixes:
|
|---|
| 500 |
|
|---|
| 501 | o Fixed missing WNOHANG handling in waitpid(), wait4()
|
|---|
| 502 | and waitid().
|
|---|
| 503 |
|
|---|
| 504 | o Corrected several severe bugs in the path resolver.
|
|---|
| 505 |
|
|---|
| 506 | o Fixed handling of paths ending with slash.
|
|---|
| 507 |
|
|---|
| 508 | o Fixed weird fork() problem which showed up as a heap
|
|---|
| 509 | deadlock.
|
|---|
| 510 |
|
|---|
| 511 | o Fixed broken _getdrive().
|
|---|
| 512 |
|
|---|
| 513 | o Made _chdrive() return -1 on error. It used to always
|
|---|
| 514 | return success earlier. (don't ask me why)
|
|---|
| 515 |
|
|---|
| 516 | o Fixed incorrect handling of -shared in GCC. It should
|
|---|
| 517 | be treated as -Zdll.
|
|---|
| 518 |
|
|---|
| 519 | o Various incorrect assertions in the strict/log build.
|
|---|
| 520 |
|
|---|
| 521 | o ...
|
|---|
| 522 |
|
|---|
| 523 | Known Limitiations/Problems:
|
|---|
| 524 |
|
|---|
| 525 | o Static linking not possible - might be fixed later.
|
|---|
| 526 |
|
|---|
| 527 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 528 | This won't change.
|
|---|
| 529 |
|
|---|
| 530 | o Missing some process group interfaces required for
|
|---|
| 531 | job control. They'll show up soon I hope.
|
|---|
| 532 |
|
|---|
| 533 | o Not tested too well. Especially the regex update.
|
|---|
| 534 |
|
|---|
| 535 | Todos before LIBC06.DLL:
|
|---|
| 536 |
|
|---|
| 537 | 0. Fix all bugs. :-)
|
|---|
| 538 |
|
|---|
| 539 | 1. Implement new ino_t scheme and reimplement opendir
|
|---|
| 540 | in BSD style while doing so (+fchdir).
|
|---|
| 541 |
|
|---|
| 542 | 2. Shared IPC structures for XSI msq, sem and shm.
|
|---|
| 543 |
|
|---|
| 544 | 3. Port string/w* functions.

| 546 | 4. Missing job pgid functions.
|
|---|
| 547 |
|

|
|---|
| 555 | --------------------------------
|
|---|
| 556 |
|
|---|
| 557 | New features:
|
|---|
| 558 |
|
|---|
| 559 | o setitimer/alarm implementation. Needs some review later
|
|---|
| 560 | the accuracy isn't extacly great.
|
|---|
| 561 |
|
|---|
| 562 | o Added a couple of missing os2emx.h features.
|
|---|
| 563 |
|
|---|
| 564 | o Some more 16-bit thunkers.
|
|---|
| 565 |
|
|---|
| 566 | Bug fixes:
|
|---|
| 567 |
|
|---|
| 568 | o Select worker called wrong tcpip function.
|
|---|
| 569 |
|
|---|
| 570 | o Incorrect assertion during thread destruction.
|
|---|
| 571 |
|
|---|
| 572 | o Fixed broken chdir and getdrive.
|
|---|
| 573 |
|
|---|
| 574 | o Improved deadlock detection (fmutex have changed,
|
|---|
| 575 | thus stdio FILE is also changed).
|
|---|
| 576 |
|
|---|
| 577 | o ...
|
|---|
| 578 |
|
|---|
| 579 |
|
|---|
| 580 | Known Limitiations/Problems:
|
|---|
| 581 |

|
|---|
| 585 | This won't change.
|

| 586 |
|

| 587 | o Missing some process group interfaces required for
|
|---|
| 588 | job control. They'll show up soon.
|
|---|
| 589 |
|
|---|
| 590 | o Doesn't evaluate trailing slash in paths as directory
|
|---|
| 591 | specifier, it's currently ignored.

| 595 | GCC v3.3.5 / LIBC v0.6 - Alpha 3:
|
|---|
| 596 | ---------------------------------
|
|---|
| 597 |
|
|---|
| 598 | This release have been timebombed and will stop working at the
|
|---|
| 599 | end of December 2004. The reason for this is that data structures
|
|---|
| 600 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 601 | quite finalized. (For your comfort the timebomb will go away when
|
|---|
| 602 | the betas start, and this is the last planned LIBC v0.6 alpha.)
|
|---|
| 603 |
|
|---|
| 604 |
|
|---|
| 605 | New Features:
|
|---|
| 606 |
|
|---|
| 607 | o Updated GCC to version 3.3.5.
|
|---|
| 608 |
|
|---|
| 609 | o Replaced the signal implementation. The new implementation
|
|---|
| 610 | is much closer to the POSIX specs and implements a lot of
|
|---|
| 611 | new interfaces.
|
|---|
| 612 |
|
|---|
| 613 | o Experimental delayed loading import libraries. emximp have
|
|---|
| 614 | a new -l option for generating such libraries. At present
|
|---|
| 615 | emximp can only generate a.out libraries of this kind - so
|
|---|
| 616 | use emxomf to convert to OMF.
|
|---|
| 617 |
|
|---|
| 618 | o The dlfcn.h functions are in LIBC now.
|
|---|
| 619 |
|
|---|
| 620 | o New functions:
|
|---|
| 621 | getgrouplist(), initgroups(), memalign(), valloc(),
|
|---|
| 622 | mprotect(), _signal_os2(), _signal_sysv(),
|
|---|
| 623 | __sigpause_bsd(), bsd_signal(), killpg(), psignal(),
|
|---|
| 624 | sigaltstack(), sigblock(), sighold(), sigignore(),
|
|---|
| 625 | siginterrupt(), sigpause(), sigrelse(), sigsetmask(),
|
|---|
| 626 | sigtimedwait(), sigvec(), sigwait(), sigwaitinfo(),
|
|---|
| 627 | sigqueue(), sigset(), getgrgid(), getpwnam(),
|
|---|
| 628 | getpwuid(), setegid(), seteuid(), setregid(),
|
|---|
| 629 | setresgid(), setresuid(), setreuid(),
|
|---|
| 630 | setrgid(), setruid(), waitid(), wait3(),
|
|---|
| 631 | wait4() and getopt_long_only().
|
|---|
| 632 |
|
|---|
| 633 |
|
|---|
| 634 | Bug fixes;
|
|---|
| 635 |
|
|---|
| 636 | o Sockets were broken on some systems. Hopefully, this
|
|---|
| 637 | should be corrected now.
|
|---|
| 638 |
|
|---|
| 639 | o stat() failed on a file open for writing.
|
|---|
| 640 |
|
|---|
| 641 | o fork() didn't work for processes which allocated lot's
|
|---|
| 642 | of memory. Fixed incorrect syncing of memory objects.
|
|---|
| 643 |
|
|---|
| 644 | o ...
|
|---|
| 645 |
|
|---|
| 646 |
|
|---|
| 647 | Known Limitiations/Problems:
|
|---|
| 648 |
|
|---|
| 649 | o Static linking not possible - will be fixed.
|
|---|
| 650 |
|
|---|
| 651 | o alarm() is still missing. Code is 80% done but didn't
|
|---|
| 652 | make it for the release.
|
|---|
| 653 |
|
|---|
| 654 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 655 | This won't change.
|
|---|
| 656 |
|
|---|
| 657 | o Missing some process group interfaces required for
|
|---|
| 658 | job control. They'll show up soon.
|

| 659 |
|

| 660 |
|

|
|---|
| 662 | GCC v3.3.4 / LIBC v0.6 - Alpha 2:
|
|---|
| 663 | ---------------------------------
|
|---|
| 664 |
|
|---|
| 665 | This release have been timebombed and will stop work at the
|
|---|
| 666 | end of October 2004. The reason for this is that data structures
|
|---|
| 667 | shared between LIBC 0.6 and all future LIBC versions are not yet
|
|---|
| 668 | finalized.
|
|---|
| 669 |
|
|---|
| 670 |
|
|---|
| 671 | New Features:
|
|---|
| 672 |
|
|---|
| 673 | o Updated GCC to version 3.3.4.
|
|---|
| 674 |
|
|---|
| 675 | o 2nd fork() implementation.
|
|---|
| 676 | All binaries are by default forkable, use the link option
|
|---|
| 677 | -Zno-fork to disable this.
|
|---|
| 678 | The fork implementation rendered _rmutex useless and it
|
|---|
| 679 | has been removed.
|
|---|
| 680 |
|
|---|
| 681 | o Symlinks using EAs. This is work in progress. One of the
|
|---|
| 682 | limitiations is that readir will not report DT_LNK yet.
|
|---|
| 683 |
|
|---|
| 684 | o Unix compartment using chroot(). This offers a
|
|---|
| 685 | redirection of '/' to the chroot'ed root. The entrance
|
|---|
| 686 | to the compartment is the '/'. The exits are drive letters.
|
|---|
| 687 | The unix compartment is inherited by LIBC child processes.
|
|---|
