scared! freedce-win32 in a cvs repository near you
by Luke Kenneth Casson Leighton 19 Sep '05

19 Sep '05

right. 48 hours later, i've got a first version of freedce-win32 to try out, which i'm actually a bit frightened of running. just in case it works :) thank goodness for pthreads-win32, otherwise i'd be up small creek. major things todo: in ipnaf.c (actually ipnaf_linux.c or even better ipnaf_win32.c) it's necessary to write an IP-interface-enumeration function. this function presumably will call GetIpAddrTable and go over all the addresses including netmasks and broadcast addresses returning information that the rpc runtime can then "listen" on - one by one. no, freedce doesn't go listening on 0.0.0.0 it binds to all "towers" whatever they're called. because i've commented this code out (stubbed) i am not expecting freedce-win32 to work straight off. once this is working, putting it in place of rpcrt4 should be relatively straightforward (and mostly very very mind numbingly boring) - a matter of "back-converting" and following the lead of dceport.h - microsoft's "wrapper" header file that allows application developers to port DCE/RPC applications to MSRPC. i say "lead" because it's woefully inadequate, representing about 10% of the functions and structs that actually need "converting", because dceport.h contains the "publicly accessible" functions. once _that's_ done, then there will be two remaining tasks: 1) check that pthreads-win32 works under wine (!) and if so, job done, otherwise it's _yet_ another emulation layer to write, but at least the source code of pthreads-win32 represents a damn good starting point 2) mash freedce's typelib output to be compatible with MSRPC binaries. this latter is no small task (but at least it could be considered). the data structures have been _totally_ mashed, by microsoft. gotta run. later. l. -- -- <a href="http://lkcl.net">http://lkcl.net</a> --

GvG and I have both seen this multiple char behaviour.

freedce-win32 - winsock joy
by Luke Kenneth Casson Leighton 18 Sep '05

18 Sep '05

progress being made. am about 10-15% the way through a compile, having previously got dcethreads to use pthread-win32 by judicious ripping out of large amounts of code. fortunately, elrond has already win32'd tng, so there is stacks of code in tng's lib/util_sock.c to rip off :) -- -- <a href="http://lkcl.net">http://lkcl.net</a> --

Re: [ros-diffs] [hbirr] 17912: The share disposition isn't necessary for FILE_READ_ATTRIBUTES.
by Gunnar Dalsnes 18 Sep '05

Is this correct? I can't see how... Even GENERIC_READ imply FILE_READ_ATTRIBUTES and using your "share disposition isn't necessary for FILE_READ_ATTRIBUTES rule" this means file sharing isnt needed for GENERIC_READ either... hbirr(a)svn.reactos.com wrote: > The share disposition isn't necessary for FILE_READ_ATTRIBUTES. > > Modified: trunk/reactos/lib/kernel32/file/file.c > > ------------------------------------------------------------------------ > *Modified: trunk/reactos/lib/kernel32/file/file.c* > > --- trunk/reactos/lib/kernel32/file/file.c 2005-09-18 13:36:29 UTC (rev 17911) > +++ trunk/reactos/lib/kernel32/file/file.c 2005-09-18 13:46:37 UTC (rev 17912) > @@ -873,7 +873,7 @@ > > SYNCHRONIZE | FILE_READ_ATTRIBUTES, > &ObjectAttributes, > &IoStatusBlock, > > - FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE, > > + 0, > > FILE_SYNCHRONOUS_IO_NONALERT); > RtlFreeUnicodeString (&FileName); > if (!NT_SUCCESS (Status)) >

found it! the "dce porting" header file
by Luke Kenneth Casson Leighton 18 Sep '05

18 Sep '05

http://examples.oreilly.de/english_examples/dce/dce_nt/dceport.h.aug95 o joy o joy. also, i found _this_!!! http://sourceware.org/pthreads-win32/ which is an implementation of pthreads on win32. _also_ i found - was reminded - by judicious searching on google, that of course entegrity.com have "PC-DCE" which is of course a _commercial_ product that has done exactly the work required: making dce (1.1? 1.2.2?) compile on Win32. including exceptions, dealing with mapping the names, blah blahhh. now. anyone got any brainy ideas on how to reverse dceport.h - in particular the thingy. wotsit. TRY/FINALLY/CATCH stuff? what i'm going to try to do is take a shot at simply compiling dcethreads - on win32. if that _works_ (the tests pass) it'll be great - it will prove two things: 1) that pthreads-win32 works 2) that the dce exception handling will fly, on win32, and _that_ means pretty much zero (urk! let's hope!) work. for now. my main goal: "GetItWorking(tm)". i couldn't care less about binary compatibility for now: i want "services" - i want srvsvcd, i want winregd, i want lsarpcd, i want samrd - all compiled, all working, using TCP/IP. i can then work on rewriting freedce's ntlmsspauth.so to be a DLL (starting off as my favourite - a stub with username and password of "test"). i can then work on writing an "ncalrpc" plugin transport (which is very straightforward: a matter of filling in about 25 functions in a vector table). and also on a ncacn_np plugin transport. "working" means that other people will then be able to focus on issues like binary compatibility. guys (wine team) i have to say this. you were utterly insane to not use freedce as your starting point - and i am still bewildered by you not even looking at its source code (which is topologically identical in almost all areas, to what you've created) or the opengroup's documentation. i say that with the greatest of respect for what you've achieved without freedce. l. -- -- <a href="http://lkcl.net">http://lkcl.net</a> --

compiling botched version of dcethreads exception using pthread-win32 - WORKS!
by Luke Kenneth Casson Leighton 18 Sep '05

18 Sep '05

okay, it's not time to get totally excited yet, but i have successfully compiled - and run, and confirmed as working on ros - some of the test programs from dcethreads (http://sf.net/projects/freedce) when cross-compiled with mingw32 and linked with pthreads-win32. this is _very_ significant because it means that there is a good chance of replicating entegrity's work - PC-DCE - with zero modifications to the freedce source code. i've cut out entirely the dcethreads "emulation" stuff, which means that dcethreads posix draft 4 compliance - including the ability to pass on thread cancellation across an RPC client/server app boundary, and including the ability to pass on signals across an RPC client/server app boundary - are completely out the window... ... but i don't care. so. the bits "remaining" in my hacked-together-version of dcethreads is _just_ the exception handling - exc_handling.c and exc_handling.h pretty much. that means that the DCE "TRY", "RAISE", "CATCH" and "EXCEPT" macros are all there. it's early days, but this is good news. now. here's what i don't want to hear from anyone: q) "why in hell's name are you doing this? why can't you just remove all references to posix threads and all references to DCE/RPC exception handling?" a) lkcl@highfield:~/sf/freedce/freedce$ find . | xargs grep pthread | wc 770 3965 64010 lkcl@highfield:~/sf/freedce/freedce$ find . -name "*.[ch]" | xargs grep ENDTRY | wc 105 248 4490 lkcl@highfield:~/sf/freedce/freedce$ find . -name "*.[ch]" | xargs grep RAISE | wc 202 731 12799 lkcl@highfield:~/sf/freedce/freedce$ find . -name "*.[ch]" | xargs grep CATCH | wc 217 685 12392 in short: modifying several thousand lines of code, by hand, is something that microsoft can happily pay some donut code-dunker to do (and did, probably back in 1990-1993) but i sure as hell ain't doing it for a proof-of-concept bit of work. q) "why are you doing this and doing it to _us_? go away!!" a) you are inflicting much pain upon yourselves, even though you probably don't know it. don't like what i'm doing, don't like what i have to say? tough - get over it: i don't have time or money to waste to stroke egos. i'll give you what time i can and what facts i can and also i will present you with an opinion: if you don't like that opinion or the way it's presented, that is your choice. live with it, deal with it or ignore it - i'll pretend i don't care which. i give you information, present you with choices: where you go from there - as neo says as the end of matrix 1.... l. -- -- <a href="http://lkcl.net">http://lkcl.net</a> --

Trunk Freeze
by WaxDragon 17 Sep '05

17 Sep '05

It's only been two weeks since I sent out the August State of the Repository, but the tree has already had 271 revisions. There have been several large commits, and trunk has had several build breakages, and instability in general. Just today we had three commits reversing and unreversing some of Alex's changes. I'm calling for a trunk freeze until several issues have been addressed. * The release build is broken. So far the string library and the usb code have been fixed. I was working with Alex on a break in the exception handling when this topic came up. * There seems to be a mysterious hang when shutting down ReactOS in qemu. I've seen it personally and heard reports of it, but since it locks up qemu so bad you can't free the mouse, no one has gotten a trace (that I am aware of). * Gunnar's win32k changes introduced several bugs, many of which were fixed, but I still feel unsure about others that may be hiding. * Hartmut fixed the MP build. See, I didn't even know that was broken. I would like to freeze the tree for 72 hours, over the weekend, allowing bugfixes only. I think we all need to grab a fresh copy and run it under every platform we have, checking all the options. According to the rules set forth, I need three developers. Who agrees to a trunk freeze?
