Known problems in this release:
===============================
Known problems at developing-time:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- When I try used *scanf* function family, then in many development systems
I found bugs for those functions. I mostly recommend use strto* function
family instead.
- Project contains "danger" code for some platforms.
(See: biewlib/sysdep/ia32/dos/timer.c, ...)
I mostly recommend use -O2 switch for gcc with any other keys.
- Wrong displayed contents of LX format, when file consist from
"Iterated data page type II" pages.
- About problem with different results of fastcall and cdecl versions
under Win32: It may be a deep-hidden bug of biew or bug of gcc,
because in some snapshots of biew it appeared also under other gcc related
development systems. (Notes: compiled with GCC CDECL version works correctly,
as compiled with Watcom and TopSpeed, where fastcall is used by default!!!)
See also topic 4.3 in develop.en(ru)
PROBLEM IS SOLVED: BUG IN GCC. This problem never occurs if gcc-2.95.3 is
installed.
Known problem at run-time (this problem of OS's):
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- When biew-OS/2 is running under OS/2 v4.5 UNI_040 in fullscreen
mode sometime it generated TRAP in POINTER$ device. (Better run it
in windowed mode or use last patched UNI_039 kernel (at 03.11.1999)
or last patched UNI_040 kernel (at 28.03.2000)).
(Author has no problems with UNI_054 (unofficial)).
- Biew-Win32 does not work properly under WinNT-4.0 SP3 and older.
- Sometime, when biew-Win32 is running under WinNT-4.0 (SP4-5) and
system perform swapping after quitting of biew You may receive GPF.
- If you have selected 'Use MMF' option in biew-Win32 and are viewing
file biew.ini, that after leaving biew you get GPF.
- 'CPU performance' of biew-DOS32 (aka djgpp) doesn't work under Win98
and may crash such systems.
What's todo:
============
(This block contain a lot of ideas. Not all will released, but most of them)
+ Try to implement MMF for DOS32 with using DPMI32 service (AS FAR AS POSSIBLE)
if it possible.
+ For procedure 'Save as (disassembler mode)' usage virtual (QUICKLY)
addresses instead of physical ones.
+ Support of ordinal entries by name. (QUICKLY)
+ Expand references prediction code. (WHEN NEW IDEAS WILL COME)
+ Accelerating video i/o (ALWAYS)
+ Fully-featured support for LE, LX, a.out, arch, (AS FAR AS POSSIBLE)
*nix formats (if possible with using binutils or scripts)
+ Disassemblers for other platform. (IF THEIR USERS WILL CODED IT)
+ OS/2 mouse-related bug fix. (AS FAR AS POSSIBLE)
+ Any base for hex-mode (probably it will digit mode viewer) (NOT URGENTLY)
+ Search and replace (non-interactive) (NOT URGENTLY)
+ capable showing the stack of calls. (IN THE NEAR FUTURE)
As effect: search of code which references given place
(NOTE: Partially done as disassembler search engine since 5.3.0-pre.5)
+ Window classes -> most effective mouse usage (NOT URGENTLY)
(this will start 6.x series)
+ Add support for dynamically linked plugins and addons. (NOT URGENTLY)
(this will in 6.x series)
+ Filters for text-mode (like rtf-view) (IN THE NEAR FUTURE)
+ User defined structures (like dbf-view) (NOT URGENTLY)
Sweet dreams: (DISTANT FUTURE)
~~~~~~~~~~~~~
+ Format-related writting. (Insert new sections, change size
of existsing sections and rebind them e.t.c.).
++ First effect: attempt to try particular restore of corrupted file.
++ Next effect: optimization of binary files on assembler level
(Note: not all formates allowed it).
