Hi Guido,
Theres a branch cygwin on sourceforge where I was doing some updates to
cygwin.
I've just checked and it's got some useful changes in it for what you
were doing: the autoconf script will configure gcc on cygwin with access
to the WIN32 API(which is not the default in current gcc versions).
It also has my win32 native async io fs module (which isn't actually
needed anymore as I've extended cygwin to have full pthreads support.
Gotta love opensource :]).
If I can make some suggestions about coding to get the changes most
easily acceptable into squid-head: (these are in addition to the squid
programmers guidelines).
1. use #ifdef SQUID_CYGWIN to surround cygwin specific code. Don't use
#ifdef __CYGWIN__.
2. try to leverage existing functions, or transparently extend them. If
you have large chunks of code that are quite different to the existing
code, you might consider adding a squid_win32 library to the lib
directory. Kinkie and I did that for some of the common NTLM code.
3. Where possible use "unix" functions or cygwin-API functions (I.E.
dlopen() not LoadLibrary()). Also cygwin has a number of functions that
extend the unix-style API onto win32, and you need to use those to run
reliably on cygwin. using "native" calls should be done with care, so as
not to conflict with cygwin's compatability code.
4. use win95 compatible functions. Cygwin is windows 95 compatible, and
so is squid for cygwin. If you __need__ to write NT only code, make a
configure option to turn on NT-only features. Only the execution as a
server feature you've listed below should need NT, so I don't think this
will be much of an issue. If it is, let me know. I suggest you look at
sshd from cygwin for service manager integration - Corinna has solved
many headaches with spawned processes and the like there.
I'm happy to provide feedback/testing as you go. Once you're getting
happy with the code, simply drop me a line and we can look at getting it
some exposure and testing, prior to getting it merged into HEAD.
lastly I'm not sure what you mean by native windows NT basic
authentication. If you mean the module you sent me a beta of before,
which talks to the LSA when given basic credentials, if you have that
ready to roll the best place to add it is as a new basic helper - it
should be able to go straight into HEAD unless there are issues with the
code. Drop me a tarball if you like.
Rob
