[itp] Coda filesystem
Hello, This is a request for feedback on whether adding the packages that make up the Coda filesystem would be something that would be supported. I haven't taken the time to produce the packages yet, but would like to know whether it would be worth my time to do so. Current state: Coda is a distributed file system (http://coda.cs.cmu.edu) that has run on UNIX-like systems for a long time. There is currently active support for Linux and NetBSD with some moderate support for FreeBSD.Over the past few years, there has been development of a kernel module for Windows that has now reached a point of stability that makes Coda run well in Windows. Coda for Windows would not work without Cygwin because the kernel module passes requests to get files from the file server to a user space daemon, venus. While there are some changes to venus for the Windows environment, venus still can not run without cygwin. The same is true for most of the user-land binaries that support the Coda filesystem. CMU currently runs a private mirror of the cygwin distribution that includes two local packages, coda-base and coda-devel. coda-base is all the cygwin binaries required and coda-devel is a meta package that just exists to provide the prerequisites to rebuild the coda-base package.There is also special built .exe that is distributed on the Coda ftp site that provides for the kernel module installation and configuration of a Coda client. (coda-base is part of base in this private mirror since the sole reason for the mirror is to support Coda.) Proposal: Several people have suggested that Coda should be distributed completely as a standard Cygwin package. Given that a postinstall.sh script could install the Coda .sys files and the required registry entries and configure a standard installation, I think it is possible to build such a package(s). Coda source has is available for all but one small part of the kernel module. Most of the source is under GPL v2. Some files are distributed under the BSD or CMU licenses. The Kernel is composed of two parts, a propritary File System Development Kit done by OSR (Open Systems Resources, Inc.) and a CMU written Coda specific file system driver. The FSDK part is available as a Coda-specific .sys file that is free of charge to Coda users. The CMU part is available with full source code under the GPL V2. There is an arrangement with OSR that allows Coda users to obtain free of charge the required files from OSR to be able to rebuild (and develop) the Coda kernel module. Other uses of the FSDK are expressly forbidden unless you purchase rights to use it from OSR. To support Coda as a standard part of Cygwin I would propose the following packages: lwp (Libs) -- A Coda specific light weight process library. rvm (Libs) -- A recoverable virtual memory library that allows persistant memory based data structures with a transaction system for consistency in the face of crashes. rpc2 (Libs) -- A remote procedure call package used by Coda (depends on lwp) codafsd(net) --The Coda file system driver, the kernel module required to make Coda work. coda (net) -- Coda binaries including venus, the client cache manager, and vice, the coda server. This package would do a standard setup for client. Would require knowledge and work to finish building a Coda server. (depends on lwp, rvm, rpc2, and coda-fsd.) This would require the coda-fsd for a server.Coda servers do not need the codafsd. An alternate package list could be lwp, rvm, rpc2, codafsd and then split coda into: coda-client (net) -- The client binaries. coda-server (net) -- The server binaries. The problem with this is that both server and client are compiled from the same source tree. It would make the coda-client and coda-server packages have the same source tar file and the source tar file would not be called either coda-client nor coda-server but just coda. The vote ... (not GTG votes, just concept votes ...) I would like to have two questions answered: 1) Is there support for adding Coda packages to Cygwin so any mirror has Coda ready to install? 2) If yes on 1, which package set, coda single package (client and server) or coda-client and coda-server packages? Thanks for taking your time to look at this. --Phil p.s. The private mirror is updated with the most current cygwin and coda packages. It is located at http://coda.cs.cmu.edu/mirrors/cygwin. The current install .exe is located at ftp://coda.cs.cmu.edu/pub/coda/winnt. (ntcoda-b4.exe)
Re: [itp] Coda filesystem
I am not an expert of current distributed files systems, but for cygwin wouldn't MogileFS be easier to implement (even though its not a fs in and of itslef). From my understanding it only requires perl and mysql I believe.

Ref: http://www.danga.com/mogilefs/ The real intent of my questions was more like: We are already managing cygwin packages in a private cygwin mirror for Coda. We would like to make the packages be on all cygwin mirrors. I wasn't asking just to bring in a distributed file system. And Coda and MogileFS are not really similar file systems. From the web site: you don't run regular Unix applications or databases against MogileFS. It's meant for archiving write-once files and doing only sequential reads. While you can't have a database file in Coda either, Coda is a full R/W distributed file system with disconnected operation. But I don't want to end up in a discussion of Coda vs any other FS, I just wanted a discussion of inclusion of Coda or not. --Phil -- Phil Nelson ([EMAIL PROTECTED]) http://www.cs.wwu.edu/nelson NetBSD: http://www.NetBSD.org Coda: http://www.coda.cs.cmu.edu signature.asc Description: This is a digitally signed message part.

Xdmcp too slow with SOME Linux accounts.
Hello. Please, I need some help with the following problem. My PC has Windows XP and is part of a WorkGroup with a Debian Linux network. I installed Cygwin, and XDMCP properly works when I login on a remote machine to ONE Linux account. But when I login to ANOTHER account with the same privileges, the connection is very slow. What could it be wrong with the second account? I know nothing about Linux, and I'd appreciate your advice. Thank you very much.

Re: Xdmcp too slow with SOME Linux accounts.
I have a similar problem, but it is not limited to a specific account. In fact, it is fairly random. Sometimes I get pretty good performance, and then it just dies. In my case, it seems to get pretty bad when I launch Eclipse, but I have to admit that Eclipse is the only GUI app that I use, so it may be gui apps in general. What I see (reported in another message) is that mouse click and keyboard seem to be very responsive, but mouse move is non-responsive. If I open a menu and move the mouse, the menu items are not highlighted. If I move the mouse several more times over the menu, ultimately a menu item is highlighted. Once it is highlighted, I can click to select the item. From a pretty uninformed perspective, it appears that mouse move events are not being forwared from my server to the client, but I'm not sure how to determine that. I am pretty confident that the problem is limited to mouse move events, and that keyboard and mouse click events are being forwarded immediately. I've seen nothing on my other post.

Re: XWIN performance
More info. If I open a terminal session in the x window, it is very responsive. I can enter any number of shell commands and the response is great. However, when I start Eclipse, my x server seems to hang. While I am seeing poor response on my x server, I can open a simple telnet session to the remote Linux box and get great response. From this I know that the problem is not cpu or memory. From everything I see, it appears that mouse move events are not being sent from my x server window on my pc to the remote system, but that is only a guess based on observation. I have no traces to prove that. What I have seen is that I can open a terminal window in the x environment and get excellent response. But as soon as I open Eclipse, the response dies. Is anyone aware of incompatabilities between the Eclipse SWT runtime and Cygwin X ? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
date reports wrong date/time with DST 2007 on windows 2003 in timezone
Hi, I just installed cygwin 1.5.24-2 on windows 2003. To test some timezone issue, I set system time to Nov 2, 2007.Then if I set TZ to PST8PDT, date command reports one hour behind the correct time. but if I unset TZ, date works well. And it looks like date can work with PST8PDT correctly in 2006 instead of 2007. Where can I find a list which cygwin can recognize ? When I tried to set TZ to America/Los_Angeles, date simply didn't recognize it and disply GMT time.

Regarding the new rxvt builds (rxvt-20050409-6 and -7)
Hello, long term user of Cygwin and lurker here. I have a small problem with the new builds of rxvt that I think nobody else has already reported (after a check of the cygwin and cygwin-apps archives). I am not able anymore to get to the system menu using the Alt-Spacebar keybord combination. As i like to work with maximized windows, I was used to press Alt-Spacebar and then n as the first thing after bringing up a new terminal. I understand that there have been some work on the handling of the alt key by Corinna Vinschen a couple of weeks ago, so I think that maybe the Alt-Spacebar was some kind of special case that has been removed from the code. Do you think that it should be possible to get the old behavior back ?

Slowness problem due to sjlj-exceptions for Octave
Dear sirs
I'm Tatsuro MATSUOKA.
This is the first time to post cygwin-app ML.
I'm now using cygwin for octave, gnuplot and shell command etc.
For the Octave society, it is very famous that building octave
current standard gcc slows the octave
because the cygwin treats the silj-exceptions very slowly.
I am purchasing the fast octave on cygwin and now trying to buid
octave with GCC Ver. 4 and GCC Ver. 3
but built with '--disable-sjlj-exceptions'.The latter trial was
partly successful. There remains bugs
but works well for most cases. I am now distributing the octave
binary built with the GCC configured
with '--disable-sjlj-exceptions'.
The URL is here
http://www.geocities.jp/tmacchant/
GCC on cygwin is updated to 3.4.4-3. That is good for most cases.
I can build the stable Octave with it unlkie GCC 3.4.4-2 or 3.4.4-1.
However slowness of Octave due to sjlj-exceptions still exits as the
mail copy that was posted
octave-maintainers ML. (That was placed at the end of the this mail.)
In the mail JWE (Prof. John W. Eaton's) comments is written.
I do not entirely agree with his opinion, but I also have a question
on sjlj-problem on cygwin.
This problem has been famous for a long time in the Octave society. I
suppose it has been also
disscussed in cygwin ML. My question is why the cygwin uses the slow
sjlj exceptions instead of
dwarf2 which was used in old cygwin at the time gcc-3.2 was used.
Recetly the Octave can be built with the mingw. The mingw GCC also
uses sjlj exceptions but the
slowness problem never be occured.
I wonder why the sjlj exceptions slows the octave on cygwin. In
other platforms including mingw, such
phenomea does not happen.
I would like to use normally prepared GCC for the octave building.
If the slowness proglem is solved, I can contribute the octave 2.9.13
to be in the cygwin package.
Pherhaps this problem is quite difficult to solve but it should be
solved for the cygwin system.

Given that Cygwin has its own packaging and distribution
system, perhaps the Cygwin binary should be dropped from
the Octave Forge site? Doesn't it just cause trouble to
have a Cygwin binary that is separate from the Cygwin
package system? I think that is especially true if the
separate binary is not even compiled with the normal
Cygwin compiler. I think it would be much better to work
with the Cygwin people and find a way to fix the GCC
problems on Cygwin systems. If that can't be done, then
maybe it's time to give up on Cygwin (at least as far as
Octave is concerned). I don't see why that would be a
problem if we have a native Windows binary that works
better anyway.

I have building a binary of octave 2.9.13 by gcc-3.4.4-3
binary that was distrubuted in cygwin package.
Using Oregonator ODE (source was placed at the end of the
mail), we compare the solving time
octave 2.9.13 built with gcc-3.4.4-3 in cygwin package
octave:1 testOregoB
ans = 9.2500
octave 2.1.73 binary in cygwin package
octave:1 testOregoB
ans = 7.0930
my testing binary built specially confgiured gcc.
octave:1 testOregoB
ans = 2.7030
To tell the truth I have not yet tested the speed of
octave built by normaly prepared gcc-3.4.4-3
For the gcc-3.4.4-3, the slowness problem concerning sjlj
exceptions has not been solved. I do not know reason why.
Anyway I will throw the problem to the cygwin ML.
The cygwin is useful tool for me. I cannot give up easily
for the possibilty the octave on cygwin.
At first I have to take part in the Cygwin ML.^^;

I have a small problem with the new builds of rxvt that I think nobody else has already reported (after a check of the cygwin and cygwin-apps archives). I am not able anymore to get to the system menu using the Alt-Spacebar keybord combination. As i like to work with maximized windows, I was used to press Alt-Spacebar and then n as the first thing after bringing up a new terminal. I understand that there have been some work on the handling of the alt key by Corinna Vinschen a couple of weeks ago, so I think that maybe the Alt-Spacebar was some kind of special case that has been removed from the code. Do you think that it should be possible to get the old behavior back ? Should be. I'll look into when I get a chance, but it won't be this week.

This is a bug in the postinstall script. It used to work, so I'm not

Note that the actual targets need .exe.
I'll fix this in the next release. Thanks for the report.

Re: Slowness problem due to sjlj-exceptions for Octave
Tatsuro MATSUOKA wrote: My question is why the cygwin uses the slow sjlj exceptions instead of dwarf2 which was used in old cygwin at the time gcc-3.2 was used. The choice to ship gcc configured for SJLJ is because it is the only way to guarantee correct behavior in all cases. The Dwarf unwinder can't unwind through a foreign frame. This means for example if you try to throw an exception from a function that was called from a Win32 callback such as the WindProc, it will fail because the frame that exists inside user32.dll or kernel32.dll (or whatever) has no data in the Dwarf2 tables. This scenario is not all that far fetched for Windows GUI programming, so the choice was made to ship gcc safe-but-correct, rather than fast-but-broken. There is a patch that has been contributed to 4.3 to fix this, and Danny Smith includes a backport of it in his 4.2 packages, which is why he is able to offer both SJLJ and Dwarf2 flavors. But moving to 4.x has its own problems, mainly that exception handling across DLLs only works for shared libgcc, and shared libgcc/libstdc++/etc aren't supported by upstream gcc on PE. Danny uses a local patch/hack to build shared target libs but it's kind of ugly and still quite experimental based on the bug reports. For Cygwin we have it a little better because we can enable shared target libraries by default like *nix distros since we have a packaging system, so we don't have to worry so much about the command line mechanics of switching between static/shared libgcc et al. But the w32sharedptr method used in cygming 3.4.x for suporting EH with static libgcc is not applicable to gcc 4.x, which means EH across shared libraries will always be broken in the case of static libgcc et al. (The same is true on other platforms like Linux, so it's not a unique situation. But MinGW is kind of unique as its users expect to build standalone apps that don't require DLLs like cygwin1.dll or libgcc.dll.)
