[uml-devel] umlwin32 - release ck04 and more ...

[Chandan K. <ch...@to...>]

Hi Folks,

I finally got a project place for umlwin32 at sourceforge.net and I have
the next version released. It has a few crucial fixes which makes it much
more stable and supports lots of commands. Download page is at:
http://umlwin32.sourceforge.net/download.html

At this point the win32 section size limitation for mmap on windows is
hurting. I have to rebuild all the binaries to make it run on umlwin32 and
shared libraries still dont work.

There were a lot of postings regarding this, and I tried all the leads and
nothing seems to work. Any tips/suggestions most welcome. If there is no
other solution, I will have to do dirty things like tinkering with page
tables and messing with physical memory (which I really really want to
avoid).

Jeff, you mentioned once about faulting in 16 pages at a time and be able
to load standard binaries (with 4K section alignment). Can you please
elaborate on this? Doing a objdump -x seemed to indicate that sections
are not contiguous ... isnt that a necessary condition to be able to do
so?

I have a new look for the project page at http://umlwin32.sourceforge.net/
I have add a developers corner for those who want to jump in to coding.
There is also a technical details page which describes current
limitations, work arounds etc. This is still under construction.

Love to hear some feedback!

Thanks,
-Chandan


--- Release notes for release ck04 ---

More stable build. ^-C does not kill the uml session. Lot more commands
work.
/sbin/halt works and should be used for halting.
Mounting hostfs works fine.

Mount root filesystem rw with standard command 'mount -o remount /'
Mount hostfs by running the script '/bin/hostfs'

Shell features:
- Piping and redirecting works
- Cannot kill a hanging process (no job control)
- Command line editing DOESNOT work
- Other things like history, functions, aliases, etc. seem to work
- ^-D works as EOF for inputting from commandline.

Lots of new commands seem to be working including:
- ksh, bash (init is linked to bash)
- python (start it as 'python -i /lib/site.py, and you can import standard
libraries.               Ignore the error it prints upon startup)
- fileutils such as: cat, rm, cp, mkdir, mv, cksum, head, tail, wc, od
etc.
- Commands like: tar, gzip/gunzip, bzip/bunzip, df, du etc
- mkfifo works and fifos actually work fine! (just make sure that
fifo-reader is in background since there is no way to kill a hanging
process)
