There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

# @(#)WHATSNEW 8.3 (Berkeley) 3/18/94

|
|
New in alpha3.4: The complex bug alluded to below has been fixed (in a
|
|
slightly kludgey temporary way that may hurt efficiency a bit; this is
|
|
another "get it out the door for 4.4" release). The tests at the end of
|
|
the tests file have accordingly been uncommented. The primary sign of
|
|
the bug was that something like a?b matching ab matched b rather than ab.
|
|
(The bug was essentially specific to this exact situation, else it would
|
|
have shown up earlier.)
|
|
|
|
New in alpha3.3: The definition of word boundaries has been altered
|
|
slightly, to more closely match the usual programming notion that "_"
|
|
is an alphabetic. Stuff used for pre-ANSI systems is now in a subdir,
|
|
and the makefile no longer alludes to it in mysterious ways. The
|
|
makefile has generally been cleaned up some. Fixes have been made
|
|
(again!) so that the regression test will run without -DREDEBUG, at
|
|
the cost of weaker checking. A workaround for a bug in some folks'
|
|
<assert.h> has been added. And some more things have been added to
|
|
tests, including a couple right at the end which are commented out
|
|
because the code currently flunks them (complex bug; fix coming).
|
|
Plus the usual minor cleanup.
|
|
|
|
New in alpha3.2: Assorted bits of cleanup and portability improvement
|
|
(the development base is now a BSDI system using GCC instead of an ancient
|
|
Sun system, and the newer compiler exposed some glitches). Fix for a
|
|
serious bug that affected REs using many [] (including REG_ICASE REs
|
|
because of the way they are implemented), *sometimes*, depending on
|
|
memory-allocation patterns. The header-file prototypes no longer name
|
|
the parameters, avoiding possible name conflicts. The possibility that
|
|
some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
|
|
now handled gracefully. "uchar" is no longer used as an internal type
|
|
name (too many people have the same idea). Still the same old lousy
|
|
performance, alas.
|
|
|
|
New in alpha3.1: Basically nothing, this release is just a bookkeeping
|
|
convenience. Stay tuned.
|
|
|
|
New in alpha3.0: Performance is no better, alas, but some fixes have been
|
|
made and some functionality has been added. (This is basically the "get
|
|
it out the door in time for 4.4" release.) One bug fix: regfree() didn't
|
|
free the main internal structure (how embarrassing). It is now possible
|
|
to put NULs in either the RE or the target string, using (resp.) a new
|
|
REG_PEND flag and the old REG_STARTEND flag. The REG_NOSPEC flag to
|
|
regcomp() makes all characters ordinary, so you can match a literal
|
|
string easily (this will become more useful when performance improves!).
|
|
There are now primitives to match beginnings and ends of words, although
|
|
the syntax is disgusting and so is the implementation. The REG_ATOI
|
|
debugging interface has changed a bit. And there has been considerable
|
|
internal cleanup of various kinds.
|
|
|
|
New in alpha2.3: Split change list out of README, and moved flags notes
|
|
into Makefile. Macro-ized the name of regex(7) in regex(3), since it has
|
|
to change for 4.4BSD. Cleanup work in engine.c, and some new regression
|
|
tests to catch tricky cases thereof.
|
|
|
|
New in alpha2.2: Out-of-date manpages updated. Regerror() acquires two
|
|
small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
|
|
in my own test program and might be useful to others for similar purposes.
|
|
The regression test will now compile (and run) without REDEBUG. The
|
|
BRE \$ bug is fixed. Most uses of "uchar" are gone; it's all chars now.
|
|
Char/uchar parameters are now written int/unsigned, to avoid possible
|
|
portability problems with unpromoted parameters. Some unsigned casts have
|
|
been introduced to minimize portability problems with shifting into sign
|
|
bits.
|
|
|
|
New in alpha2.1: Lots of little stuff, cleanup and fixes. The one big
|
|
thing is that regex.h is now generated, using mkh, rather than being
|
|
supplied in the distribution; due to circularities in dependencies,
|
|
you have to build regex.h explicitly by "make h". The two known bugs
|
|
have been fixed (and the regression test now checks for them), as has a
|
|
problem with assertions not being suppressed in the absence of REDEBUG.
|
|
No performance work yet.
|
|
|
|
New in alpha2: Backslash-anything is an ordinary character, not an
|
|
error (except, of course, for the handful of backslashed metacharacters
|
|
in BREs), which should reduce script breakage. The regression test
|
|
checks *where* null strings are supposed to match, and has generally
|
|
been tightened up somewhat. Small bug fixes in parameter passing (not
|
|
harmful, but technically errors) and some other areas. Debugging
|
|
invoked by defining REDEBUG rather than not defining NDEBUG.
|
|
|
|
New in alpha+3: full prototyping for internal routines, using a little
|
|
helper program, mkh, which extracts prototypes given in stylized comments.
|
|
More minor cleanup. Buglet fix: it's CHAR_BIT, not CHAR_BITS. Simple
|
|
pre-screening of input when a literal string is known to be part of the
|
|
RE; this does wonders for performance.
|
|
|
|
New in alpha+2: minor bits of cleanup. Notably, the number "32" for the
|
|
word width isn't hardwired into regexec.c any more, the public header
|
|
file prototypes the functions if __STDC__ is defined, and some small typos
|
|
in the manpages have been fixed.
|
|
|
|
New in alpha+1: improvements to the manual pages, and an important
|
|
extension, the REG_STARTEND option to regexec().
