| 146 | GCC v3.3.5 / LIBC v0.6:
|
|---|
| 147 | -----------------------
|
|---|
| 148 |
|
|---|
| 149 | There was a build problem with the first attempt at releasing.
|
|---|
| 150 | This is the 2nd attempt, hope I got it right this time...
|
|---|
| 151 |
|
|---|
| 152 | WARNINGS
|
|---|
| 153 |
|
|---|
| 154 | There are several incompatible interface changes. So, you'll have
|
|---|
| 155 | to rebuild static libraries and it's a good idea to do the same
|
|---|
| 156 | thing for dynamic libs and programs too.
|
|---|
| 157 |
|
|---|
| 158 | The build is not tested as much as I would've liked. I'm very
|
|---|
| 159 | pressed on time as usual, but I really wanted to get the 0.6 stuff
|
|---|
| 160 | out now. I can only hope everything still builds and works.
|
|---|
| 161 |
|
|---|
| 162 |
|
|---|
| 163 | The Project is Moving
|
|---|
| 164 |
|
|---|
| 165 | The source code has been migrated to subversion and now resides
|
|---|
| 166 | on the svn.netlabs.org server. The server also provides an issue
|
|---|
| 167 | tracker and project management service called trac. Check it
|
|---|
| 168 | out at http://svn.netlabs.org/libc/.
|
|---|
| 169 |
|
|---|
| 170 | The source code for this release (and any bugfix releases on
|
|---|
| 171 | the 0.6 code base) can be checked out using this url:
|
|---|
| 172 | http://svn.netlabs.org/repos/libc/branches/libc-0.6
|
|---|
| 173 |
|
|---|
| 174 | Developers who wish to contribute to the 0.7 code will have to
|
|---|
| 175 | diff against the trunk. There are several pending restructuring
|
|---|
| 176 | tasks on 0.7, so don't expect everything to build fine or work
|
|---|
| 177 | properly while those are still open. Anyway, the url:

|
|---|
| 179 |
|
|---|
| 180 | Users are encouraged to join the [email protected] mailing list
|
|---|
| 181 | and use that list for questions rather than the InnoTek form. If
|
|---|
| 182 | you think you've found a bug, you should first ask on the mailing
|
|---|
| 183 | list, and if I decide it's a *real*, *new*, bug I'll open a
|
|---|
| 184 | ticket for it and address it.
|
|---|
| 185 |
|
|---|
| 186 | Developers which have patches for real bugs or enhancements can
|
|---|
| 187 | create trac tickets and drop me or the gcc-user list a mail (we
|
|---|
| 188 | haven't figure out how to get email notifications from trac yet).
|
|---|
| 189 |
|
|---|
| 190 |
|
|---|
| 191 | New features:
|
|---|
| 192 |
|
|---|
| 193 | o Added __libc_Back_gfProcessHandlePCBatchScripts and
|
|---|
| 194 | __libc_Back_gfProcessHandleHashBangScripts (globale
|
|---|
| 195 | variables) to turn on/off script handling in exec/spawn.
|
|---|
| 196 | Very useful for shells.
|
|---|
| 197 |
|
|---|
| 198 | o Changed the default stack of emxomfld and emxbind to 1MB,
|
|---|
| 199 | it used to be 8KB and 8MB.
|
|---|
| 200 |
|
|---|
| 201 | o open() can now open directories like on unix, and fchdir()
|
|---|
| 202 | can chdir to the opened directories.
|
|---|
| 203 |
|
|---|
| 204 | o Implemented much of the unix-attributes-in EA stuff.
|
|---|
| 205 |
|
|---|
| 206 | o Implemented getdirents(), will be used to replace
|
|---|
| 207 | opendir/readdir/seekdir/telldir/closedir in 0.7.
|
|---|
| 208 |
|
|---|
| 209 | o Implemented the fcntl interface for setting and clearing
|
|---|
| 210 | the O_NONBLOCK flag on sockets.
|
|---|
| 211 |
|
|---|
| 212 |
|
|---|
| 213 | Bug fixes:

|---|
| 219 |
|
|---|
| 220 | o Fixed fork bug in shm.
|
|---|
| 221 |
|
|---|
| 222 | o Fixed spawn/exec bug where .exe was appended too early
|
|---|
| 223 | preventing configure and other scripts without suffix
|
|---|
| 224 | from being executed.
|
|---|
| 225 |
|
|---|
| 226 | o Fixed several signal bugs (deadlocks, sigsuspend, pause).
|
|---|
| 227 |
|
|---|
| 228 | o Fixed symbol truncation problem in emxomf.
|
|---|
| 229 |
|
|---|
| 230 | o Fixed a generic error handling bug in ioctl, write, read,
|
|---|
| 231 | dup and dup2 which was causing incorrect errno values.
|
|---|
| 232 |
|
|---|
| 233 |

| 333 | GCC v3.3.5 / LIBC v0.6 - Beta 5:
|
|---|
| 334 | --------------------------------
|
|---|
| 335 |
|
|---|
| 336 | Thanks to Lorne, Froloff, nickk and Andy for sending me patches,
|
|---|
| 337 | debugging problems and/or testing fixes.
|
|---|
| 338 |
|
|---|
| 339 | New features:
|
|---|
| 340 |
|
|---|
| 341 | o Added support for __declspec(dllexport), _Export
|
|---|
| 342 | and __declspec(dllimport), the latter being a stub.
|
|---|
| 343 | This also included adding N_EXP to the a.out format.
|
|---|
| 344 |
|
|---|
| 345 | o Lot's of math stuff, mostly untested.
|
|---|
| 346 |
|
|---|
| 347 | o Optimized zeroing of new file space in ftruncate and
|
|---|
| 348 | chsize with knowlegde about the filesystem. HPFS, JFS
|
|---|
| 349 | and FAT will do the zeroing for us.
|
|---|
| 350 |
|
|---|
| 351 | o Support for unlocked stdio, with both BSD and GNU
|
|---|
| 352 | extensions implemented.
|
|---|
| 353 |
|
|---|
| 354 | o Execute .cmd, .bat, .btm and hash-bang scripts.
|
|---|
| 355 |
|
|---|
| 356 | o Respect single quotes in argument handling (sed craze).
|
|---|
| 357 |
|
|---|
| 358 | o Ported fts.h and the BSD implementation.
|
|---|
| 359 |
|
|---|
| 360 | o Ported BSD sysctl. (Does not include the tcpip v4.1
|
|---|
| 361 | sysctl() bits yet.)
|
|---|
| 362 |
|
|---|
| 363 | o Ported the FreeBSD implementation of SysV semaphores
|
|---|
| 364 | and shared memory.
|
|---|
| 365 |
|
|---|
| 366 | o Env.var. LIBC_THREAD_MIN_STACK_SIZE can be used to
|
|---|
| 367 | specify the minimum stack size for new threads. The
|
|---|
| 368 | default minimum is 4096 bytes.
|
|---|
| 369 |
|
|---|
| 370 | o Ported (lib)intl from glibc.
|
|---|
| 371 |
|
|---|
| 372 | o New gcc arguments -Zargs-wild and -Zargs-resp.
|
|---|

|
|---|
| 489 | type internally.
|
|---|
| 490 |
|
|---|
| 491 | o fxsave/fxrstore problem in fork(). (This isn't tested

|
|---|
| 495 |

|---|
| 519 | o Corrected NP_NBLK define in os2emx.h.
|
|---|
| 520 |

| 540 |
|
|---|
| 541 | 3. Missing job pgid functions.
|
|---|
| 542 |
|

|
|---|
| 545 | objdump is constantly broken between LIBC versions.
|
|---|
| 546 |
|
|---|
| 547 | 5. Figure out the EA exclusive read access trouble.
|
|---|

|
|---|
| 562 |
|
|---|
| 563 | o wchar.h and wctype.h and much of the non-stream functions
|
|---|
| 564 | declared therein are implemented. Though, the FreeBSD
|
|---|
| 565 | string/w*.c functions are still in the porting queue.
|
|---|
| 566 |
|
|---|
| 567 | o Added __mcount stub to all LIBC DLLs but the .prf one which

|---|
| 568 | is forwarding __mcount from kProfile.dll.
|
|---|
| 569 |
|
|---|
| 570 | o DosLoadModuleEx and DosFreeModuleEx was created to support
|
|---|
| 571 | loaded modules over a fork(). dlopen/dlclose backend was
|
|---|
| 572 | changed to use these.
|
|---|
| 573 |
|
|---|
| 574 | o Fixed rand() range problem. Using the BSD code for this
|
|---|
| 575 | too, which means a new algorithm.
|
|---|
| 576 |
|
|---|
| 577 | o Update all BSD source-files (not headers) to FreeBSD 5.3
|
|---|
| 578 | level.
|
|---|
| 579 |
|
|---|
| 580 | o New functions:

|
|---|
| 596 | wcstoull(), wcstoumax(), wctob(), wctrans(), wctype(),
|
|---|
| 597 | towlower(), towupper().
|
|---|
| 598 |
|
|---|
| 599 |
|
|---|
| 600 | Bug fixes:
|
|---|
| 601 |
|
|---|
| 602 | o Fixed missing WNOHANG handling in waitpid(), wait4()
|
|---|
| 603 | and waitid().

|---|
| 604 |
|
|---|
| 605 | o Corrected several severe bugs in the path resolver.
|
|---|
| 606 |
|
|---|
| 607 | o Fixed handling of paths ending with slash.

|
|---|
| 610 | deadlock.
|
|---|
| 611 |
|
|---|
| 612 | o Fixed broken _getdrive().
|
|---|
| 613 |
|
|---|
| 614 | o Made _chdrive() return -1 on error. It used to always
|
|---|
| 615 | return success earlier. (don't ask me why)
|
|---|
| 616 |
|
|---|
| 617 | o Fixed incorrect handling of -shared in GCC. It should
|
|---|
| 618 | be treated as -Zdll.
|
|---|
| 619 |
|
|---|
| 620 | o Various incorrect assertions in the strict/log build.
|

|---|
| 623 |
|
|---|
| 624 | Known Limitiations/Problems:
|
|---|
| 625 |
|
|---|
| 626 | o Static linking not possible - might be fixed later.
|
|---|
| 627 |
|
|---|
| 628 | o Job control will only be applied to thread 1 in a process.
|
|---|
| 629 | This won't change.
|
|---|
| 630 |
|
|---|
| 631 | o Missing some process group interfaces required for
|
|---|
| 632 | job control. They'll show up soon I hope.
|
|---|
| 633 |
|
|---|
| 634 | o Not tested too well. Especially the regex update.

|
|---|
| 658 | New features:
|
|---|
