Although Send() will return indicating the data has been sent, nagling should hold the actual packet back until it is full, however this should only happen if there is unconfirmed data i.e. no ACK. To avoid any confusion, you can switch nagling off with the TCP_NODELAY flag I'm interested in this bug, but I'm not around tonight to play about with it :( ************************************************************************ The information contained in this message or any of its attachments is confidential and is intended for the exclusive use of the addressee.

How does one make a MP build anyway?
by WaxDragon 21 Dec '05

21 Dec '05

Gang, I have been unsuccessful in building a working MP bootcd for a while now. I conferred with Hartmut about some of the details, but still cannot get it working. This is what I tried: 1. Set MP=1 in config.xml 2. Hacked the hal xml files to make halmp.dll hal.dll on the bootcd, per Harmut Index: halx86/up/halup.xml =================================================================== --- halx86/up/halup.xml (revision 20282) +++ halx86/up/halup.xml (working copy) @@ -1,6 +1,6 @@ <module name="halup" type="kernelmodedll"> <importlibrary definition="../../hal/hal.def" /> - <bootstrap base="reactos" nameoncd="hal.dll" /> + <bootstrap base="reactos" /> <include base="hal_generic">../include</include> <include base="ntoskrnl">include</include> <define name="_DISABLE_TIDENTS" /> Index: halx86/mp/halmp.xml =================================================================== --- halx86/mp/halmp.xml (revision 20282) +++ halx86/mp/halmp.xml (working copy) @@ -1,6 +1,6 @@ <module name="halmp" type="kernelmodedll"> <importlibrary definition="../../hal/hal.def" /> - <bootstrap base="reactos" /> + <bootstrap base="reactos" nameoncd="hal.dll"/> <include base="hal_generic">../include</include> <include base="ntoskrnl">include</include> <define name="_DISABLE_TIDENTS" /> 3. make bootcd, as normal The resulting bootcd fails to boot under "qemu -smp 2" with the following trace: (./ntoskrnl/ke/main.c:295) --------------------------------------------------------------- (./ntoskrnl/ke/main.c:296) ReactOS 0.3-SVN (Build 20051221-r20282) (hal/halx86/mp/apic.c:420) Getting VERSION: 50011 (hal/halx86/mp/apic.c:423) Getting VERSION: 50011 (hal/halx86/mp/apic.c:454) Getting ID: 0 (hal/halx86/mp/apic.c:457) Getting ID: f000000 (hal/halx86/mp/apic.c:554) CPU0: (hal/halx86/mp/apic.c:555) Physical APIC id: 0 (hal/halx86/mp/apic.c:556) Logical APIC id: 0 (hal/halx86/mp/apic.c:557) 00000000 00000000 f0000000 (hal/halx86/mp/apic.c:584) CPU0: (hal/halx86/mp/apic.c:585) Physical APIC id: 0 (hal/halx86/mp/apic.c:586) Logical APIC id: 1 (hal/halx86/mp/apic.c:587) 00000000 01000000 f0000000 (hal/halx86/mp/apic.c:588) 0 (hal/halx86/mp/apic.c:619) enabled ExtINT on CPU#0 Used memory 131072Kb (./ntoskrnl/mm/mminit.c:386) Kernel Stack Limits.

I would like to get this worked out and documented somewhere. WD -- <Russell> argh <Russell> iterator shenanigans :/

Loopback problem
by Ge van Geldorp 21 Dec '05

21 Dec '05

I've been tracking down a problem with ibrowser being extremely slow for me (it took 64 sec to load http://www.reactos.org). It turns out to be a problem associated with the loopback interface. The attached test program (gcc -o loop.exe loop.c -lws2_32) is the minimum test program to demonstrate the problem. It occurs when you send a small amount of data over the loopback interface when there is no pending recv (so you send, then start a recv for the data, then another send, then another recv, no recv waiting while you send). Sequence of events: - Start first send - TCP/IP stack queues the data at the receiving end - First send returns - Start first recv - Queued data is retrieved, but it is determined that there's plenty of space in the TCP window left, so there is no ACK sent back - First recv returns - Start second send - tcp_output determines that the connection is not idle (there is some un-ACKed data) and queues the data at the sending end - Second send returns - Start second recv - Since there is no data waiting at the receiving end, recv just sits there - An internal timer with a period of 2.5 sec expires - The timer proc notices that there is an ACK pending - ACK is sent back to the sending end - Sending end determines connection is idle now and sends the queued data to the receiving end - Timer proc terminates and reschedules itself - Data has now arrived at the receiving end and can be retrieved by the waiting recv. Again no ACK is sent back - Second recv returns - Third send starts, queues its data at sending end and returns - Third recv starts, has to wait 2.5 sec for the internal timer to timeout and then returns - etc. Although I understand what's wrong, I have a bit of difficulty trying to figure out how to fix it. Attached is a proposed fix, which basically attacks the problem at the sending end by removing the check if the connection is idle or not. With that fix the loop.c program works as I expect and http://www.reactos.org loads in a much more reasonable 2-3 sec in ibrowser. The problem that I have with the fix is that it's a change in code we borrowed from the BSD stack. I can hardly imagine that a piece of software so heavily used as the BSD stack would have such a fundamental problem. Any thoughts? GvG

You need to understand the context in which the message is used. If it's system debug message, it will normally be hardcoded in. If it's a generic Win32 error message it should be picked up with FormatMessage. These will be output in the users preferred language via the LANG_SYSTEM_DEFAULT or LANG_USER_DEFAULT flags. Then you have simple MessageBox outputs which can be picked out of a resource file, but are generally hardcoded in. There are many other situations and usages, but I'll stop there. As already said, becoming a programmer is the only real way of understanding it all. > Well, you say I should learn some things like structures of resource > files, do you have any links for me? There are thousands of C tutorials on the net.
