I would consider it off-topic for this list unless the core of the product uses
Cygwin.  Announcements of products using Cygwin should be considered on topic,
IMO.

    Thanks, Earnie. It seems that Free Software really have problems,
and vendor patents are not the biggest of them. Remember one of the
latest Freshmeat editorials where Linux community was compared with
guys kicking each other. Lack of generalization...

     But I write this not to release funny thought (nor to be killed

authorities) whether following will be appropriate.

      I'm going to benchmark as many POSIX implementations as I will
be able to put my hands on (this will ammount to very-very little, and
generally I'd prefer someone else to do this, but I'm afraid noone will
bother). Cygwin will be included. So, will results (with appropriate
disclaimer and links to tests sources) be interesting for cygwin
community/appropriate for cygwin mailing list?

Personally, I think posting comparative data is useful to this list...

I have no problem with comparative benchmarks (and I don't think that
cygwin will be a speed demon).  The theory is that these will actually
mention the program that is the focus of this mailing list.

I am not sure what is translating into problems in the Free Software
community.  Perhaps the original poster would like to provide more
detail about what he is referring to; specifically, with regards to
Cygwin, of course.

Don't be so sure.  I've used GCC on Interix for a while... let's just
say that Cygwin rocks.

The Interix product relies heavily on the POSIX subsystem, instead of
shared memory as Cygwin does.  For many of my user applications the
subsystem process actually consumes more CPU time than the application!

Presumably, the tradeoff is between performance and security.  Interix
isn't vulnerable to the same exploits as Cygwin.

Interesting.  We have been trying to improve (and succeeding in
improving) Cygwin's runtime performance but that's been done comparing
Cygwin to Cygwin-past and not so much by doing benchmarks against
other systems I think.

Have people run any benchmarks comparing Cygwin, Uwin, NuTcracker,
Interix, anything else out there?

Great! Have you found any way to improve the performance of commands like 'ls'
against remotely mounted file systems? I frequently have things like

 NET USE * \\SERVER\SHARE

where SERVER is located on the far end of a PPTP link to a system a few
thousand miles (18-22 hops over the Internet via an ISDN connection on my end)
and doing an 'ls' is unuseably slow (and I think I've tried various releases
from b17 to b20.1). So, I usually try to remember to use the "command prompt"
and the DIR command which works just fine. I also wave perl scripts over the
remote directories (scripts that do file globbing and file system traversals)
and they run fine...but they don't try to get all the file info that an 'ls
-l' would - ought to try out an 'ls' command from the Perl Power Tools set
sometime...

At any rate...since 'ls' is hardwired into my fingers and I wander into these
directories often enough, using cygwin can be painful, so I haven't gotten
fully into playing with it yet.

That would be useful info!

I think Geoff was referring to improvements that are already in Cygwin.  If you
don't see any changes then there aren't any improvements.

basically, reason is following: ls uses "stat" syscall to obtain file
information. stat returns a handful of parameters, including inode,
permissions and others. to obtain _all_ that info, cygwin must open file
(see stat_worker function at winsup/cygwin/syscalls.cc). opening every
file on network share is pretty slow.

luckily, most of time application don't need _all_ stat information.
for example, if you need to get file time or owner or size only,
there's no need to open file. so, some time ago i've proposed to make
cygwin1.dll export function "stat_lite", which works similar to
"stat", but receives additional flags, showing which fields are of
interest to application. so, after that you can recompile ls to
utilize this function. i've compiled custom version of midnight
commander, and directory browsing becomes several times faster for
slow remote shares.

note: you have to recompile your application to utilize "stat_lite"
function.

So do I.  If it mentions Cygwin, it's relevant... if it doesn't mention
Cygwin, it's not appropriate for this list... at least that's what
others seem to be saying, and I tend to agree.

Speaking for myself... I don't mind the occaisional off-topic
announcement, but there is always a danger that they can snowball into a
long non-relevant discussion thread, subverting the real purpose of this
list.  I've seen it happen elsewhere.

So have I.  That's my primary concern.

Hmm.  I would like to receive opinions on whether people consider this
announcement to be off-topic.

We don't see any DJGPP announcments here.  We don't see any UWIN or Interix
traffic.  Maybe I'm wrong, but I don't think that Mikey announced here, either.
(How's that for giving a plug to all of cygwin's competitors?)

I don't think that announcements of (alternative) Posix-over-Win32 layers are
on topic here but if everyone else disagrees, my opinion can be changed.

    I greatly appologize! I wanted to include these possible
appologies in original announcement, but just thought: after all, we
all doing same thing, namely gnu-win32 (btw, isn't that trademark of
Cygnus, the Red Hat company?). While this list is of course dedicated
and owned by cygwin, it's de-facto mother list of all
Unix/Gnu-on-win32 lists, and have grown others (such as mingw32) off
itself. I also think my little stuff indebted to cygwin by its birth,
and hoped I could use that wonderful possibility - to announce it
once, and rejoice cygwin people with that announcement. And of course, my
little stuff is not competitor of cygwin (competitor? ridiculous. have
years of work of many people were put into it? does it offer that level
of support?), but rather an (spiritual) offspring targeted at niche
intentinally left out by cygwin. After all, that's what free software
is all about.

   I once again would like to say that was one-time announcemnt for
information of gnu-win32 comminity. Under no circumstances I planned
to continue that announcing or start discussions here. If even that
was illicit, I would like to ask pardon from all cygwin community.

  Thank you for your support.
