- The UCL license is GPL, this will cause problems for the antivirus
|
||||
programs which can't use the uncompressor because of this. Or am I wrong?

For 0.95:

- FIXME: what do we want in 1.00 ???
|
||||
|
||||
- add NRV2D for dos/exe (use by default when >= 400 kB)
|
||||
|
||||
- implement switch `-m' for method: 1 NRV2B, 2 NRV2D
|
||||
|
||||
- DLL problem under NT ? is this fixed ???

or resource names a,b,c
|

3 - medium - ml) rebuild exports
|

3 - difficult) don't compress the BSS section and other holes.
|

4 - medium - ml) fix when objectalign < 0x1000
|

4 - easy - ml) put the original offset of moved resources somewhere into
|
||||
the res.dir. (if it's safe to do)
|
||||
4 - ??? - ml) fix FIXMEs
|
||||
5 - medium - ml) try to put the preprocessed imports & relocs back to their
|
||||
original section if possible this could save some virtual memory

4 - ???)
|
||||
- test with AOUT binaries
|
||||
- test with Java binaries
|

- make a compressed program suid. what happens ?
|

|

5 - difficult) rewrite the whole stub in assembly

SPARC

3 - easy - ml) finish support - should generate byte-identical versions
|

for all formats (except those which are using Packer::getRandomId())

|

DJGPP2
|
||||
======
|
||||
|
||||
1 - ???) do we support overlays at all ???
|
||||
|
||||
5 - ???) fix file extension handling when the --coff option is set
|
||||
|
||||
|
||||
FOR 0.95
|
||||
========
|
||||
|
||||
- enable automatic dependency tracking
|
||||
|
||||
1 - mfx) determine when to use NRV2D, find best c_flags values for
|
||||
NRV2B & NRV2D (see util/runtest.sh)
|
||||
|
||||
5 - boring - mfx) Finally fix all screen and UI problems. How boring...
|
||||
Probably should think about the whole system (printf vs. fprintf vs.
|
||||
con_fprintf...)
|
||||
|
||||
5 - policy - ml+mfx) Discuss a default C++ style (GNU indent 2.2.3)
|
||||
with Laszlo and use it. Or maybe Artistic Style?
|
||||
|
||||
10) Examine why pod2text breaks lines within something like `B<--coff>'.
|
||||
(pod sucks anyway. unfortunately all alternatives as well.)
|
||||
|
||||
|
||||
MISC
|
||||
====
|
||||
|
||||
3 - difficult ml) The first two sentences of the README look too much like
|
||||
those from the aspack docs. Laszlo, could you rewrite this ?
|
||||
|
||||
1 - easy - mfx) Check whether the compressed size of the executable is
|
||||
really smaller than the uncompressed
|
||||
|
||||
1 - ??? - mfx) Implement a more informational interface.
|
||||
Probably add some global functions in msg.cpp.
|
||||
Should think about the requirements first, i.e. should there be
|
||||
some simple hierarchies (header1, header2, ...) etc. ?
|
||||
Could use the `-v' switch for enabling this (or `-i' ??).
|
||||
- Something like this would be fine: (with colors :-)

||||
[Processing kernel32.dll]
|
||||
[Import]
|
||||
3 DLL.
|
||||
Original size: 12345 bytes.
|
||||
Preprocessed size: 6789 bytes.
|
||||
[Relocations]
|
||||
Original size: 50000 bytes.
|
||||
Preprocessed size: 25000 bytes.
|
||||
[Exports]
|
||||
<warning> exports compressed (try --compress-export=0 if needed)
|
||||
[TLS]
|
||||
Added 56 bytes TLS data.
|
||||
Added 5 fixup records.
|
||||
[Resources]
|
||||
Directory size: 1234 bytes.
|
||||
Resource data size: 100000 bytes.
|
||||
Compressed resources: 8 (99900 bytes).
|
||||
Not compressed resources: 1 (100 bytes).
|
||||
|
||||
3 - ???) delete temporary files when something wrong happens
|
||||
|
||||
4 - easy - ml) Add a `--486' option to use bswap on the 32-bit formats.
|
||||
|
||||
4 - easy - ml) consider removing 'sbb bp,bp' or "or ebp,-1" when not needed
|
||||
|
||||
5 - ???) idea: --subfile=xx compress xx. subfile: we'd need a list_subfiles
|
||||
for this...

GOALS FOR 0.90
|
||||
==============
|
||||
|
||||
- Provide additional NRV2D stubs for all 32-bit formats. Try to do this
|
||||
in a generic way so that we can possibly add more algorithms.
|
||||
Start by adding a `--nrv2d' switch.
|
||||
|
||||
FOR 0.90
|
||||
========
|
||||
|
||||
/ update the output of `--help'
|
||||
|
||||
- filters: implement the missing scan() function for f_cto32.
|
||||
Maybe could use this to try to find an optimal filter (e.g.
|
||||
if level >= 9) based on the counts.
|
||||
|
||||
- filters: could we have use for a f->firstcall info field ?
|
||||
|
||||
TODO
|
||||
====
|
||||
|
||||
- all formats: more thoroughly test the exe-header in canPack()
|
||||
and throw exceptions when encountering bad values.
|
||||
|
||||
- experiment with filters
|
||||
|
||||
- for small programs (e.g. < 64k) try an additional algorithm (like
|
||||
the non yet finished NRV2C) to see if it gives better compression ?
|
||||
|
||||
/ make checkerg++ work -> test
|
||||
|
||||
- fix file extension handling when the --coff option is set
|
||||
|
||||
- set up an "official" test suite
|
||||
|
||||
- finish documentation
