Hi Bernd!
after fixing a memory corruption in HTMLHELP [1],
"The memory corruption happened in openZipFile() by overwriting
data segment elements following zipfile, especially the UTF conversion
tables. zipfile stores an absolute path, so it was changed to
zipfile[MAXPATH] instead zipfile[MAXFILE], as MAXFILE=8 and MAXPATH=255"
That is quite a difference, an 8 byte buffer for path names which need
255 :-o
I need to publish a new binary. I noticed that the APACK [2] compressed
file is 53067 bytes, while the UPX compressed file is 55292 bytes, so
~4% better
So instead of 103.6 sectors, you get almost 108 sectors. If cluster
size is at most 4 kB, there will be a measurable difference in disk
usage. Seems low priority to me :-)
UPX 5.02 settings : --8086 --best
APACK 1.00 settings: -1 -x
Would the APACKed file also work on 8086? Does HTMLHELP in general?
I tend to stick to UPX, preferably the UPX-UCL variant.
Thanks for finding the bug in HTMLHELP! Must have been there for years?
:-o
