hello chris,
I have been playing with the cygwin toolkit since last october, (B20,
and a number of the snapshots)
and have a few observations to offer which I can not explain:
- the problem of 100% cpu after completion of (most) a command in 'bash'
has been solved since the recent
snapshots, but I notice a serious performance degradation compared to
say january.
A generation of perl 5.5.660 took 11 minutes (tar, some scripting,
make, make test, make install), and
now only the tar takes already 15 minutes, while my system becomes
sluggish.
- the CYGWIN="binmode" environment variable seems to have no effect,
probably caused by bash 2.03,
which I generated without changing anything after the 'configure'.
Should it have anything special for cygwin??
I start my bash by a C-wrapper-program, compiled with cygwin.
- I changed to mounting all partitions in 'binary' mode, and since then
'cat' works fine. Before a
cat cat.exe >a.a
would terminate after ~2000 characters.
- Since these binary mounts the perl generation (make) comes in a loop
during 'dllwrap' and 'dlltool'. I see
a growing number of ds01.0 ds02.o ..... files, and have to kill the
'dll' processes.
I did goto version 5.5.670 of perl, and made sure that there were no
text files with embedded CR/LF,
since these behave strangely with binary mounts (at least sh scripts).
- the tar executable distributed with the recent snapshots does not
behave well despite the binary mounts.
tar -cf - . | tar -tf -
produces a error, that disappears if I re-make the tar.exe from the
distibuted cygwin-src
I hope this does not sound too negative, because I like the cygwin
product.
greetings

I ran into this problem as well, with bash-2.03. I do not know if there
are any special compile-time directives that will correct this problem;
I reverted to the cygnus-distributed bash-2.02, which fixed the problem.

I haven't seen any of these problems, and I've built every perl from
5.5.640 to 5.6.0-RC1. Generating the initial perl.dll does take a long
time (3-4 minutes on my K6 200). Just let it run to completion?

Are you sure this is not related to the binmode pipe problem you
described earlier?

You have two versions of the cygwin1.dll. DON'T COPY THE CYGWIN1.DLL TO THE
WINDOWS SYSTEM DIRECTORY.
