-0.9.31 2 April 2010
-
- Upgrade notices from previous versions.
- o On x86_64 the format of /var/run/utmp changed compared to previous
- versions. To retain compatibility with glibc we now define
- __WORDSIZE_COMPAT32. If you are certain that you will never use
- glibc nor run in i386 mode on your x86_64 installation, you can
- remove this definition from wordsize.h.
- Otherwise you have to delete /var/run/utmp on x86_64 hosts when
- upgrading to 0.9.31
- o The SHARED_LIB_LOADER_PREFIX was renamed to a single path
- component called MULTILIB_DIR and defaults to 'lib'.
-
-0.9.27 12 January 2005
-
- This has been a long time in the making... Release highlights:
- o New stdio implementation
- o New optimized string functions
- o Major improvements to the shared lib loader
- o Shared libraries work properly on powerpc
- o Debugging works on mips
- o New architectures: frv, nios, nios2, bfin
- o Linux 2.6.x kernel support
- o Lots and lots of bug fixes
-
- This release is NOT binary compatible with uClibc 0.9.26 or any earlier
- release, so be prepared to recompile your software if you are still using
- an old version of uClibc.
-
- -Erik
-
-
-
-0.9.26 3 January 2004
-
- This simply adds a fix for a pthread bug that was noticed a few hours
- after the previous release. Otherwise identical to 0.9.25.
-
- This release remains binary compatible with uClibc 0.9.21-25 as long as
- you take care to avoid any configuraton changes that will break things.
- We _were_ planning to break binary compatibilty in this release, but
- decided to hold those changes so we could push out a bugfix release.
-
- We _will_ break binary compatibilty in the upcoming 0.9.27 release to
- implement a few things we have been postponing. That should hopefully be
- the last ABI change before we freeze the ABI for the upcoming 1.0.x
- stable uClibc series.
-
-Release highlights:
- o A trivial fix for a pthread bug
- o Nothing else
-
- -Erik
-
-
-
-0.9.25 3 January 2004
-
-See Changelog.full for the complete list of who did what.
-
-Note:
- This release remains binary compatible with uClibc 0.9.21-24 as long as
- you take care to avoid any configuraton changes that will break things.
- We _were_ planning to break binary compatibilty in this release, but
- decided to hold those changes so we could push out a bugfix release.
-
- We _will_ break binary compatibilty in the upcoming 0.9.26 release to
- implement a few things we have been postponing. That should hopefully be
- the last ABI change before we freeze the ABI for the upcoming 1.0.x
- stable uClibc series.
-
-Release highlights:
- o Fixed a ton of problems found using the LTP and NIST test suites.
- The few remaining test failures are obscure corner cases, such as
- a few functions that fail (correctly) with incorrect errno values.
- o Fixed a longstanding pthreads bug -- amoung other things, you no
- longer need to explicitly add -lpthread for perl to work.
- o Added some sh optimized string functions
- o Added sh64 shared library support
- o The default malloc implementation has been replaced, and will
- now actually free memory when told to do so.
- o Both popen() and exec*() now behave themselves per SuSv3
- o Better 2.6.x kernel header support
- o Added support for Position Independent Executables (PIE) on x86
- o Lots of other minor cleanups
-
- -Erik

-0.9.24 15 December 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:
- This release remains binary compatible with uClibc 0.9.21-23 as
- long as you take care to avoid any configuraton changes that will
- break things.
-
- We currently plan to break binary compatibilty in the upcoming 0.9.25 to
- implement a few things we have been postponing, which will hopefully be
- the last change....
-
-Release highlights:
- o Fixed several silly configuration problems
- o Added arm optimized string functions
- o Lots of minor cleanups

-
-0.9.23 13 November 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:
- This release is binary compatible with uClibc 0.9.21 and 0.9.22 as
- long as you take care to avoid any configuraton changes that will
- break things. Enabling or disabling things like soft-float,
- locale, wide wchar support, or changing cpu type are all good
- examples of things that will break binary compatibility.
-
-Release highlights:
- o Fixed several silly configuration problems that were
- present in the 0.9.22 release.

-0.9.22 8 November 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:
- This release is binary compatible with the 0.9.21 release
- if you take care to avoid any configuraton changes that
- might break things for you (i.e. enabling or disabling things
- like soft-float, locale, wide wchar support, or changing cpu
- type are all good examples of binary incompatible config options).
-
-Release highlights:
- o Added e1, microblaze, and sh64 architectures.
- o Much improved soft-float support
- o Rewrote the passwd and group handing functions
- and implemented all SuSv3 required reentrant
- versions.
- o Reworked and updated the Config system. You now
- get to select your target architecture with the
- config system.
- o Fixed pthreads for mmuless m68k systems
- o Added some x86 optimized string functions.
- o Lots and lots of bugs fixed.

-
-0.9.21 9 September 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:
- This release is not binary compatible with earlier releases.
- Sorry about that. We have never promised to provide binary
- compatibility until we hit version 1.0, and even then, if
- you change your configuration.
-
-Release highlights:
- o uClibc now has full ANSI/ISO C99 locale support (except
- for wcsftime() and collating items in regex).
- o Added support for using pre-generated locale data, making
- it easy for mere mortals to use uClibc w/locale support.
- o Lots of new tuning options added to trade size
- for features, allowing for smaller static binaries.
- o The "dlopen()'ing libraries that depend on libraries"
- problem was fixed.
- o A new scanf implementation. Well tested, but
- brand new so watch for obscure bugs...
- o Reworked and updated the Config system, adding several
- nice new features which we now use.
- o Lots and lots of sundry bug fixes and cleanups.

-
-0.9.19 3 March 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:

- o Fixed mips shared library loader bug that caused segfaults
- o Major update to the pthreads library. Should improve performance.
- o Fixed uClibc's shared library loader so we can properly debug
- applications using pthreads (must use gdb 5.3 or newer which
- was compiled using uClibc).
- o Made uClibc's ldd act just the glibc provided one (i.e. relying
- on the shared lib loader to do the work) when it is possible to
- doi so, and only rummage about the ELF headers when we have no
- other choice (such as when using 'ldd' on cross compiled stuff).
- Miles Bader
- o header file updates for v850 architecture
- o Fixed v850 crt0.S __uClibc_main argument stack space

-
-0.9.18 12 February 2003
-
-See Changelog.full for the complete list of who did what.

-0.9.17 25 January 2003
-
-See Changelog.full for the complete list of who did what.
-
-Note:
-
- I have always reserved the right to make binary incompatible changes as
- needed prior to the "1.0" release. This release is a good example of
- that. A few bugs turned up that needed to be fixed and the only good way
- to fix them was to change some fundamental data structure sizes. So I did
- just that. As a result, this release is _NOT_ binary compatible with
- earlier releases -- you will need to recompile your applications.

- Tobias Anderberg
- o cris architecture updates
- Erik Andersen

- o Always build crt1.o as well as crt0.o to minimize the need to mess
- with the compiler
- o Rewrote powerpc crt0.S to properly handle ctors/dtors
- o Removed unimplemented and legacy stuff from our header files to
- make configure behave better
- o Made the lib loader also support libs in /usr/X11R6/lib by default
- o Config system updates
- o networking function updates
- o Large file support updates
- o Lots of other little bug fixes and cleanups

-
-This is a minor bugfix release.
-
-See Changelog.full for the complete list of who did what.
-Release highlights:

- were both enabled.
- o Eliminate duplicate define warnings in wstring.c.
- o Fix potentially broken preprocessor comparisons.
- o Erik was an idiot and broke thread locking in exit(),

- compiling PIC code (crtbegin.o and crtend.o) otherwise.
-
- -Erik
-
-
-
-
-0.9.13 9 August 2002
-
-Security Fixes

-See Changelog.full for the complete list of who did what.
-Release highlights:
- o Add full shared library support for Hitachi SuperH (sh)
- thanks to Stefan Allius and Edie C. Dost
- o Lots of reentrance cleanups (we should now be fully
- reentrant when compiled with pthread support).
- o Miles Bader implemented a new mmap based malloc which is much
- smarter than the old "malloc-simple", and actually works, unlike
- the old "malloc". This is now the default for mmu-less systems
- and should greatly help reduce memory fragmentation and wastage.
- o Reworked syscall handling for i386 and ARM, smaller and cleaner.
- o Support for the syscall() function on i386 and ARM
- o The uClibc g++ wrapper now automagically adds the proper include

- this time around. It still didn't last time.
- o Libcrypt now passes conformance tests
- o Nearly complete locale supporti thanks to a lot
- of hard work by Manuel Novoa III. This stuff is
- _way_ smaller than glibc's

- *) glob / fnmatch tests fail
- *) regex should pass AT&T conformance tests
- *) Finish hiding uClibc internal symbols from our exported namespace
- *) Add system for generating minimal system call asm wrappers that abuse
- the C ABI to minimize amount of register/stack manipulation
- *) Explicity add some sortof CONFIG_LINUX_2_2_ABI, CONFIG_LINUX_2_4_ABI
- and CONFIG_LINUX_2_6_ABI type options, rather than having the abi
- depend on the selected set of kernel headers. This will likely also
- require that we provide a set of kernel headers (probably a derivitive
- of Mazur's linux-libc-headers) that can supplies the 2.2, 2.4, and 2.6
- kernel abi.
- *) Documentation updates:
- *) Write a uClibc HOWTO document
- *) Update README document
- *) Update INSTALL document
- *) Update docs/Glibc_vs_uClibc_Differences.txt document
- and fully document all differences between the feature
- set of uClibc and glibc.
- *) Update docs/uClibc_vs_SuSv3.txt document
- *) Update docs/threads.txt document
- *) Write man pages for ldd and ldconfig utility binaries
- *) Implement some mechanism (perhaps encoded in the .so name,
- perhaps using an abi tag magically embedded into each object)
- for flagging config options that break the ABI. Options
- such as UCLIBC_HAS_SOFT_FLOAT, UCLIBC_HAS_THREADS, UCLIBC_HAS_LOCALE,
- and perhaps others (finalize list) produce a lib with a differing
- ABI. Make it so apps cannot use an ABI mis-matched uClibc.
- This is most easily done using symbol versioning...
- *) Implement the long double versions of math funcs on interrested
- arches using wrappers on top of the double versions (size / precision
- trade off where size clearly wins).
- *) Make all small objects (>~50 bytes) into either inlines or
- into a static library
- *) Cleanup / rewrite sysconf.c. It should get some information
- from ldso (such as HZ). Other stuff it currently just makes
- up, which is obviously wrong. Also bits/uClibc_clk_tck.h
- needs to be updated at the same time to get proper HZ values.
- *) poll emulation using select() for old 2.0.x uClinux kernels
- in libc/sysdeps/linux/common/poll.c fails some python self-tests.
- Of course, modern systems using the actuall poll() syscall work fine.
- *) Cleanup/scrub all the Makefile copyright junk
- *) Fix dlopen, for both static and dynamic cases, and make it
- fully comply with SuSv3
- *) check if sched_getcpu is only pulled in where it should be
- *) remove HANDLE_OLDER_RLIMIT, NEW_GETRLIMIT (conditionalize on
- ugetrlimit, it seems, else use the modern variant)
- *) simplify exec*() in the light of execvpe (perhaps single internal
- impl); USE_GNU for execvpe (and other GNU extensions, see psm).

-TODO list for AFTER the uClibc 1.0.0 release:

- date -s 011903142038 sets epoch to roll over in a few seconds (2^31)
- *) Add support for Linux 2.6.x fast vsyscalls
- *) Enable pristine source tree builds
- *) Fix regex so it isn't so stinking big
- *) Fix glob so it isn't so stinking big
- *) run 'nm -D --size-sort -t d libuClibc-0.9.26.so' and work on the
- biggest things (i.e. stuff at the end of the list) to make

-Arch specific TODO:
--------------------------------------------------
- alpha:
- ldso is not implemented
- arm:
- update crt1 code again for nommu (http://bugs.uclibc.org/view.php?id=538)
- recruit jbowler and integrate thumb support
- frv:

- hppa:
- errno.c test segfaults causes segfault in clone.S (seems to be in glibc too)
- i386:
- add support for fast system calls
- ia64:
- ldso is not implemented
- m68k:
- ldso lazy relocation doesnt work
- sh64:
- ldso is reasonably broken, presently requiring additional
- coaxing/threatening.
- sparc:
- need a sigaction.c since common one doesnt work (signal tests)
- ldso needs to be updated since it's totally broken atm
- vax:
- pthread support, linktime warning support (implies GAS patches),
- general touchups, testing, ldso.
-
-
------------------------------------------------------------------------------
-Manuel's todo:
-
- 1) Little things that need fixing:
- ----------------------------------
- a) Fix bug in *printf: outdigit precison bug
- b) Check that gnu/bsd extension members tm_gmtoff and tm_zone in struct tm
- are respected where they should be.
- c) Implement the obstack printf funcs for glibc compat.
- d) Implement glibc 'a' flag for scanf string conversions.
- e) Allow use of the older non-table-based ctype functions when using
- stub locale support. (smaller)
- f) __drand48_iterate should be void
- g) alphasort vs. versionsort. The former seems to be SVID, the latter GNU
- i.e. reverse to what we currently do. The latter is unimplemented.
- h) ponder removal/configs to turn off: __xpg_*, bsd_signal, dysize,
- getw/putw, utimes,
-
- 2) Additional str{f|p}time issues.
- ----------------------------------
- a) Spacing issue wrt strptime.
- b) Support locale specific alternate digits. (data is in place)
- c) Support locale era in year designations. (data is in place)
- d) Deal with mb format string issues in strftime.
- e) Implement wcsftime.
-
- 3) Other locale issues (my implementation):
- -------------------------------------------
- a) Do a little more clean up of ctype and wctype.
- b) Rework of the locale data organization to make using locales reasonable
- when staticly linking. (mmap)
- c) Rewrite the locale data generation tools to process the text specifications
- rather than relying on glibc.
- d) Adapt regex lib to use my collation data and add the necessary collating
- item tables to support SUSv3 required features.
- e) transliteration of unsupported wchars in 8-bit locales (like glibc).
- f) Support ISO/IEC 14652 draft locale extensions (LC_PAPER, etc).
- g) Implement strfrom.
- h) Shift-state codeset locale support?
-
- 4) Misc:
- --------
- a) Port uClibc to other OSs (including elks), or even bare metal (libgloss).
- b) Write a space-efficient gettext substitute, to avoid storing large amounts
- of redundant data.

If you want to compile uClibc with NPTL support, then answer Y.
- IMPORTANT NOTE! NPTL requires a Linux 2.6 kernel, binutils
- at least version 2.16 and GCC with at least version 4.1.0. NPTL
- will not work with older versions of any above sources. If you
- ignore any of these guidelines, you do so at your own risk. Do
- not ask for help on any of the development mailing lists.
-
- !!!! WARNING !!!! BIG FAT WARNING !!!! REALLY BIG FAT WARNING !!!!
-
- This is experimental code and at times it may not even build and
- even if it does it might decide to do random damage. This code is
- potentially hazardous to your health and sanity. It will remain
- that way until further notice at which point this notice will
- disappear. Thank you for your support and for not smoking.
