- 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?
|
|
|
|
- Rearrange this TODO list, sort by categories, add a priority (1-5)

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 ???

2 - easy - mfx + ml) new switch(es) : do not compress resource types x,y,z
|

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

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

|
|
======
|
|

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 :-)

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
|
