As far as I can see, there is code in ChooserPage::OnMessageCmd that responds to clicking any given one by calling keepClicked() or changeTrust(xxx), and there's nothing else anywhere else that could query or in any way respond to the state of the buttons or that tests which one is checked or anything. Why do you say they have a persistent influence? I'm /very/ convinced that they change the state of the selection when clicked and it's a one-shot, what bit of the code are you looking at that suggests otherwise? Max, ping? Have you looked at this? If I don't hear from you in the next few hours I'll check in part 2 of the patch on its own like you asked, but I'm still convinced part 1 is good as well. cheers, DaveK -- Can't think of a witty .sigline today
Gtk-CRITICAL **: file gtkobject.c: line 1034 - Something missing?
Hi, I'am trying to run xmms on a remote linux while the gui is on my local cygwin-xfree. Xmms (1.2.10) starts well and is visible. When I try to load mp3's into the playlist the file selection windows opens. After selecting a file I get the following message: Gtk-WARNING **: invalid class type `gchar' in cast to `GtkObject' Gtk-CRITICAL **: file gtkobject.c: line 1034 (gtk_object_set_data): assertion `GTK_IS_OBJECT (object)' failed.

Re: windows XP : cygwin -X server not opening
To make a long story short: My Questions are: Whats causing the null screen fn ReparentWindow null screen fn RestackWindow how can InitQueue - Calling pthread_mutex_init InitQueue - pthread_mutex_init returned InitQueue - Calling pthread_cond_init InitQueue - pthread_cond_init returned work without running cygserver? and also winInitMultiWindowWM - Calling pthread_mutex_lock () winMultiWindowXMsgProc - Calling pthread_mutex_lock () work when there is no cyserver running? Cygserver is responsible to deliver the following services. * XSI IPC Message Queues. * XSI IPC Semaphores. * XSI IPC Shared Memory. According to http://www.cygwin.com/cygwin-ug-net/using-cygserver.html His XWin doesn't run thru winDetectSupportedEngines.

Re: windows XP : cygwin -X server not opening
I really don't know if the select () which fails is used on a Network fd or one of the queue fd's within InitQueue. But the final error may be just the result of the previous errors. There is a good chance that it is this way because the error happens within winClipboardProc which usually is on the local machine not on the network. Alex http://www.aiengine.org You did know that?

No idea how well any of them work, but it's easy enough to test them out. And what would I need to do to run an external window manager? You'd have to tell Xwin to run in rootless mode, and you'd have to run the appropriate external window manager, both in startxwin.bat.

Gettext use on Cygwin
I use Cygwin, latest packages across the board, on WinXP Home Edition, fully patched. I specifically use it to compile VLC, a cross platform video encoder/streamer/client. VLC uses gettext, the bootstrap for it includes: Autopoint -f With older cygwin gettext, 0.14.1, during the bootstrap the autopoint would generate: tar: Skipping to next header tar: Archive contains obsolescent base-64 headers gzip: stdin: invalid compressed data--crc error gzip: stdin: invalid compressed data--length error tar: Error exit delayed from previous errors Copying file ABOUT-NLS However, it would still end up creating the intl directory needed. As of gettext 0.14.5, however, this does not occur. I tried commenting out the rm line at the end of autopoint version 0.14.5, and saw that cvs_dir and work_dir are, indeed, both missing an intl directory. Therefore, when autopoint executes the part of copying files from $work_dir/archive, there is no intl there to be copied. I personally have no idea why this is occuring, though strongly suspect it is related to the gzip and tar errors that I show above, that occur when autopoint is executing the line: gzip -d -c $gettext_dir/archive.tar.gz | (cd $cvs_dir tar xf -) What I ended up doing, in my own copy of autopoint, was to modify it to the following: if test `find archive -type f -print | wc -l` = 0; then cd .. rm -rf $cvs_dir $work_dir func_fatal_error infrastructure files for version $ver not found; this is autopoint from GNU $package $version fi #MFM addition cd archive mkdir intl cd intl for file in `find $gettext_dir/intl -type f -print | sed -e s,^$work_dir/archive/,, | LC_ALL=C sort`; do cp $file . done cd .. cd .. #end of MFM addition cd .. This is clearly an ugly hack -- I explicitly create the intl directory in $work_dir, and copy the intl files over from shared/gettext/intl. On the other hand, it does work, and after spending multiple hours trying to reinstall tar and gzip, and reinstalling Cygwin's gettext 0.14.5, then trying local VLC builds of gettext (a pull of the latest gettext source files), this is the best I could come up with for something that does work.

I reinstalled both gzip and tar, same problems showed. tar (GNU tar) 1.15.1 gzip 1.3.5 Apologies for not including the cygcheck -- I spent several hours trying to find any way to report the problem I've been seeing, actually hunting for a direct method to send a report to gettext people, ended up with a bunch of bad e-mail bug-reporting addresses. The bug-gettext (aka bug-gnu-utils) mailing list at lists.gnu.org is currently down - the GNU project had a massive database failure last month that has severely impacted their mailing lists for several weeks. But if you are only experiencing the problem on cygwin, then the right thing to do is contact the cygwin lists first, so the package maintainers can decide whether it really is an upstream problem or just a porting issue. Attached is a text file containing the cygcheck output. And indeed, my guess that you might be running text mounts is confirmed: . /cygdrive user textmode,cy gdrive C:\cygwin / system textmode C:\cygwin/bin /usr/bin system textmode C:\cygwin/lib /usr/lib system textmode C:\cygwin\usr\X11R6\lib\X11\fonts /usr/X11R6/lib/X11/fonts system binmode . /cygdrive system textmode,cy gdrive Use the 'mount' tool to remount things as binary, and see if that improves the situation (development tools don't tend to work very well in text environments). If I independently run gzip -d archive.tar.gz I see it decompress the archive to a .tar If I then run Tar xf archive.tar I see the archive directory with expected contents (ABOUT-NLS,v and the set of directories and files below it, including intl) But for whatever reason, the complete command line: gzip -d -c $gettext_dir/archive.tar.gz | (cd $cvs_dir tar xf -) Generates the errors originally reported. So it would seem that somehow running things through the pipe, with text mounts underneath, may be causing the textmode corruption. I'll see if I can reproduce that locally (I don't normally use textmode, for a reason). To check once more, I commented out my change to autopoint, as well as commenting out the rm at the end of autopoint that erases the temp directories. The output of my bootstrap shows: + autopoint -f tar: Skipping to next header tar: Archive contains obsolescent base-64 headers gzip: stdin: invalid compressed data--crc error gzip: stdin: invalid compressed data--length error tar: Error exit delayed from previous errors Copying file ABOUT-NLS + aclocal-1.9 -I m4 -I extras/contrib/share/aclocal + autoconf Your changes are a hack to work around the symptoms, not solve the original problem. While it works for you, I doubt that it will be applied either upstream or to the official cygwin gettext distribution. If the intl directory was being created, after the Copying file ABOUT-NLS line I would expect to see output lines related to creating and populating the intl structure in my project. And when I check my project root directory, I see that a temporary $cvs_dir has been created. This directory contains a CVSROOT subdirectory, and an archive subdirectory. The archive subdirectory only contains ABOUT-NLS,v -- no intl subdirectory (or anything else). If I revert to the Cygwin gettext 14.1 package, I still see the complaints about gzip and tar, but for some reason that intl directory, and files, do get created in my project trunk. Since it was working with 14.1 I ignored the
Need tech info on need_invisible() and CreateWindowStation
Hi, first, let me introduce why I need technical infos on the need_invisible() stored in fhandler_console.cc. We have a Win32 tool (not cygwin) at the root starting (spawning) lot of cygwin programs at the same time for performing multiple processing at the same time so : Win32 root program forking for example 10 threads, each of these threads will spawn a CygWin process (bash, make, ect...) sure, each of this cygwin process (like make) will start still sub cygwin process or Win32 child process. We sometimes randomly (but frequently) encountered lot of hangs (0%cpu) or loops not ending (25%cpu for example) in CygWin tools (bash, egrep, ...). All other non cygwin programs (for example we use a gnu makefile spawning some Microsoft Visual Studio devenv.exe instances) never failed work correctly. But as I said, sometiles cygwin processes hang. We don't have any issue in a mono processing system with one child process tree. We tried with the last version of cygwin but it did not resolve our issues. Looking into the gmame cygwin forum, I found lot of information reporting that these cygwin issues could be generated by a uncorrect SharedSection. We already increased the non interactive SharedSection value as we use non interactive to run our system, sure, it resolve lot of hangs in non CygWin programs but CygWin still continues to hang as described above. Investigating on my issue, I tried before disturbing you to take myself a look in the CygWin code. then I saw that Cygwin calls itself a CreateWindowStation in fhandler_console.cc to allocate also a non interactive console for unused tty (if I understood correctly). So I have lot of concerns on this, so, lot of questions... My first question, is can you explain exactly me regarding the code when/in which condition exactly with an example (bash calling make for example make calling sh as sub process), when this code is called ? I did not exactly understand when ? How is shared this Window station between all cygwin programs ? I saw that you call the GetProcessWindowStation GetUserObjectInformation finally check the WSF_VISIBLE flag to see if you need to create one CygWinInvisible non interactive window station at the end a default non interactive desktop. So, If running multiples instances of cygwin programs even if these instances are not some child instances of others cygwin programs, they will be attached to the already existing CygWinInvisible window station. But My concern here is when you have multiple isntances of cygwin program started in parallel for multi processing tools for example... Can these instances meet a race/concurrent/conflict access to this part of code detecting together that there is no cygwininvisible winstation created so calling together CreateWindowStation (or there are maybe somewere above int he code/call stack some semaphore managed not for encountering a race condition in this code ?) ? Also, looking into the Cygwin code, there is no cygwininvisible winstation created (check on check the WSF_VISIBLE ) when it is already started from a non interactive desktop like a service (with the interact with desktop nt service checkbox unchecked), so the cygwin process uses the winstation where it is running, am i right ? If cygwin programs run under an interactive winstation this code is so called, all cygwin programs running in this winstation will be automatically attached to the cygwininvisible winstation... In this case, if having in an interactive session, lot of cygwin process, they will fill the cygwininvisible could overflow/saturate it ? So, I think a similar issue could no appears in my environment as cygwin already run under an invisible winstation... ? Why these two last questions ? because as we run lot lot of child programs, our parent/root win32 program automatically create an invisibile winstation+its desktop for attaching each child process tree. in this manner of managing windows limitation, we have to find the correct sharedsection value for allowing all child programs tree to run+creating a specific number of winstation+desktop (for example ten winstation+its desktop one child process tree under its of these). that's the only way (from my point of view;) )actually as workaround to manage the computer load under win32 :( I know that you will redirect me to the how to report a cygwin problem document but these questions are to increase my knowledges so if needed, to report my future requests with the best details ;) Also, as running strace to find exactly where cygwin process lock/hang on our architecture is really complex, this why I also investigating on this way. I also saw that (If i looked in the correct version), that Cygwin allocate at the end of the dll segment a block of memory for exchanging data with the child cygwin programs that sometimes (if i understoound everything) due to dlls reallocation, this shared segment could be not

Problems with setup.exe updates when cygwin is running
I've just had a bunch of problems with cygwin, including but not limited to those experienced here: http://www.cygwin.com/ml/cygwin/2006-01/msg00798.html http://www.cygwin.com/ml/cygwin/2006-01/msg00798.html As it turns out in the end, these have been down to running setup.exe with cygwin running and getting the mesage about needing to reboot. However, even after reboot the system has been broken: inodes listed as changed, cp saying that files were changed during copy, etc. This all seems to be down to the setup.exe run. After reverting everything to previous, the problem has gone away entirely. I suggest that setup.exe needs robusting, at the very least giving a strong warning on update BEFORE changing things if the files are in use. A general message to close running programs before installing is used as a cop-out by lots of other programs and is usually overkill, and thus ignored. So it needs to be clear and specific, if it is to be effective. Also, having used google to search the archives, the cygwin mailing list does seem to be pretty unhelpful on some of these issues as most enquiries from those not deeply steeped in the lore of cygwin get quoted the problem reporting FAQ rather than any attempt made to help them. Maybe I've been spoiled by the support I've received on other free forums and from commercial companies who don't tell their customers to push off. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

RE: bash, find | xargs grep
I wish that fork would fail with errno set, so that bash's error message is not so confusing; but that is besides the point. Running out of memory during forks is not a bug in bash, find, or xargs, but a limitation of Windows. If anyone has ideas on how to reduce the frequency of fork failures, patches are more than welcome, but the main developers have pretty much tried everything imaginable. The solutions (workarounds?) on this list have generally been to disable the third-party .dll that is causing the interference. Hi Eric, Regarding your previous message, regarding Microsoft information, if you are talking about the SharedSection limitation which makes program running out of memory even if lot of memory is free, the only solution is not to link use user32 objects as defined in this Microsoft technote (http://support.microsoft.com/default.aspx?scid=kb;EN-US;184802) : Desktop heap is allocated by User32.dll when a process is in need of user objects. If an application is not dependent on User32.dll, it will not consume desktop heap. One another problem is to be sure that no other third parties program introduces user32 dependencies in the running process like antivirus as you said Eric ... so to be sure that all others implemented libraries don't call also APIs in user32.. Another way, is to write a Desktop Manager for configuring the number of cygwin process you want to run inside to have a new desktop created automatically when this limit is reached to re-attach the instance of a new cygwin process under one of these desktop when another cygwin program exited from it... But it needs also more communication through pipes other in cygwin1.dll for having cygwin programs communicating with the cygwin desktop manager... That's only an idea, but it is not also really simple to configure needs to add more parameter in cygwin like : number_of_desktops number_of_process_in_a_desktop maybe another option like : attach_non_process_desktop_to_caller_one meaning that if cygwin try to start a non cygwin application it will attach this application in the winstation/desktop of the caller/launcher of the first cygwin program in the tree I don't know if you could consider my mail as a contribution, but I hope (in the case of you was talking about this limitation ;) ) ;) Louis - -- Life is short - so eat dessert first!

And when we look at
http://cygwin.com/packages/gcc-core/gcc-core-3.4.4-1
we see there's no crtbegin/end at all. I'm guessing that these two .o files
were supposed to move from gcc-core to the gcc-gpc package in between 3.3.3
and 3.4.4, that the 3.3.3-3.4.4 gcc upgrade helper package removed them prior
to installing the new ones, but that for some reason gcc-gpc has stayed at
3.3.3 and there's no new version with the crtbegin/end files in
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.4 available yet.
So, this counts as a kind-of packaging error where something's fallen
between the gaps of a partially-finished version upgrade. I'll raise it on
the -apps list.
In the meantime, your best bet for a workaround would be to manually grab a
copy of the file and drop it into that directory; hopefully there's little
enough difference between the 3.3.3 and 3.4.4 versions of it that this will
solve your problem, but it's not guaranteed.
You said in your original post that the file 'does exist', but I bet it's
the wrong one - I checked my system and found that I still had copies lying
around under the mingw subdir, but they are probably only good for -mno-cygwin
compiles, so you probably need to grab a copy of gcc-core-3.3.3-3.tar.bz2 from
your local mirror and unpack it yourself.
[ ten minutes later ]
OK, I just tried it, and it almost worked first time. Turns out I also
needed to copy the libgcc.a from the tarball into the gcc-lib/3.3.3 subdir.
Then I got hw.pas to compile and run!
cheers,

Memory leak in vsnprintf
I believe I have found a memory leak in the Cygwin version of
vsnprintf(). If it is called with a NULL 'str' parameter and a 0
'length', it leaks a BUFSIZ-sized buffer. (Per C99 and SUSv3, calling
vsnprintf() with a NULL 'str' and 0 'length' is a way to find out how
big the formatted string would be without actually storing it anywhere.)
I see that Cygwin's vsnprintf() comes from newlib. Should I report this
to them instead?
Here is an example program:
#include stdio.h
#include stdarg.h
int
waste_it(char *fmt, ...)
{
int ns;
va_list a;
va_start(a, fmt);
ns = vsnprintf(NULL, 0, fmt, a);
va_end(a);
return ns;
}
main(int argc, char *argv[])
{
int i;
int n;
for (i = 0; i 1; i++) {
n += waste_it(%s foo %d, hello, 49);
}
}
This program will consume quite a lot of memory on Cygwin.

I have created a 14MB file and the results were:
On Linux: 4 seconds
On Cygwin: 44 Seconds
The test were made on 3 different platforms, and the results the same.
Cygwin is not just 2X slower but 11X slower, each is too much.
It looks like this is a TCP_NODELAY issue. You tend to get the problem
if a socket is used interactively, which means, being used for reading
and writing in arbitrary order.
Unfortunately the Nagle algorithm on Windows is somewhat sluggish. I've
tried your echo_server with and without Nagle disabled. Sending a 17
Megs file from my Cygwin box to an echo_server on my Linux box takes
between 4 and 5 seconds.
Sending a 17 Megs file from Linux to an echo_server on Cygwin takes
about 55 seconds. However, when I disable the Nagle algorithm in the
echo_server, it takes between 2 and 9 seconds. I don't understand the
unexact interval, but I also don't see how that could be Cygwin's fault.

Weird. The difference between gawk-3.1.5-2 and gawk-3.1.5-3 is in
theory only the fact that -2 missed to make CRLF-LF conversion on
stdin while -3 does CRLF-LF conversion.
This is the script, if that makes a difference. It is in the middle
of a pipe, receiving input from sort and giving output to another
instance of sort. Everything should have unix-style line-endings.
The pipe is running under ash. The script actually used a tab
character instead of the \t escape sequence. I changed it to \t
below in the hope that that might be easier to read in this email.
gawk ' BEGIN { FS = OFS = \t }
{
Key = $2 \t $3 \t $4
InfoNew[Key] = $5
DateNew[Key] = $1

InfoOld[Key] = InfoNew[Key]
DateOld[Key] = DateNew[Key] }
if (InfoNew[Key] != InfoOld[Key]) {

InfoOld[Key] = InfoNew[Key]
DateOld[Key] = DateNew[Key] }
} END {

Do I need to send anything else?
Can you embed this in a minimal testscript to reproduce the effect,
together with a few lines (10) of a typical input file?

Sorry to have bothered you about this.
I did comparison tests with gawk-3.1.5-2 and gawk-3.1.5-3. Playing with
print statements I found that gawk was not hanging. Timing was not
consistently different between gawk-3.1.5-2 and gawk-3.1.5-3, so the
unexpectedly long run times must have been do to other reasons. (As
this is Windows, on a network, and I don't have admin privileges, its
hard to say what those other reasons might be.)
Anyway, I apologize again for having raised a false alarm.
And thanks for all the great work everyone has done on cygwin!

Re: Need tech info on need_invisible() and CreateWindowStation
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 http://cygwin.com/acronyms/#PCYMTWLL - your email was just awful to read (go look at http://cygwin.com/ml/cygwin/2006-03/msg00402.html to see why we ask for some common sense netiquette - wrapping at 76 characters is typical) My first question, is can you explain exactly me regarding the code when/in which condition exactly with an example (bash calling make for example make calling sh as sub process), when this code is called ? I did not exactly understand when ? You've already taken the first step of looking at the code. The joy of open source is that you can now compile your own version of cygwin1.dll with debugging information, and instrument it to print a message when it is used, or put a breakpoint in the debugger, or many other options. The best way for you to understand what the code is doing is dive in and learn it yourself. How is shared this Window station between all cygwin programs ? I saw that you call the GetProcessWindowStation GetUserObjectInformation finally check the WSF_VISIBLE flag to see if you need to create one CygWinInvisible non interactive window station at the end a default non interactive desktop. So, If running multiples instances of cygwin programs even if these instances are not some child instances of others cygwin programs, they will be attached to the already existing CygWinInvisible window station. But My concern here is when you have multiple isntances of cygwin program started in parallel for multi processing tools for example... Can these instances meet a race/concurrent/conflict access to this part of code detecting together that there is no cygwininvisible winstation created so calling together CreateWindowStation (or there are maybe somewere above int he code/call stack some semaphore managed not for encountering a race condition in this code ?) ? If you can generate a simple test case that shows an actual bug, or produce a patch with good explanation of why it is needed, it will be appreciated. Otherwise, assume that cgf knew what he was doing when he wrote that code, and that any races are unintentional. Also, looking into the Cygwin code, there is no cygwininvisible winstation created (check on check the WSF_VISIBLE ) when it is already started from a non interactive desktop like a service (with the interact with desktop nt service checkbox unchecked), so the cygwin process uses the winstation where it is running, am i right ? If cygwin programs run under an interactive winstation this code is so called, all cygwin programs running in this winstation will be automatically attached to the cygwininvisible winstation... In this case, if having in an interactive session, lot of cygwin process, they will fill the cygwininvisible could overflow/saturate it ? So, I think a similar issue could no appears in my environment as cygwin already run under an invisible winstation... ? Why these two last questions ? because as we run lot lot of child programs, our parent/root win32 program automatically create an invisibile winstation+its desktop for attaching each child process tree. in this manner of managing windows limitation, we have to find the correct sharedsection value for allowing all child programs tree to run+creating a specific number of winstation+desktop (for example ten winstation+its desktop one child process tree under its of these). that's the only way (from my point of view;) )actually as workaround to manage the computer load under win32 :( Since you already seem to know a lot about the semantics of invisible windows stations, you may already have a headstart on writing any patches to cygwin's usage of them. I know that you will redirect me to the how to report a cygwin problem document but these questions are to increase my knowledges so if needed, to report my future requests with the best details ;) Also, as running strace to find exactly where cygwin process lock/hang on our architecture is really complex, this why I also investigating on this way. I also saw that (If i looked in the correct version), that Cygwin allocate at the end of the dll segment a block of memory for exchanging data with the child cygwin programs that sometimes (if i understoound everything) due to dlls reallocation, this shared segment could be not allocated correctly... can this generate hanging/locking process ? If cygwin cannot allocate shared memory as desired, that process dies with an error message. It should be a quick death; if a process hangs then there is some other issue at play. Just a last question (I know that my mail is already big), but Why sometime, cygwin also try to impersonate child processes ? Because that is how cygwin emulates POSIX semantics. Thank's very a lot for your contributions ;) This will really help me to troubleshoot my issue in our system/configuration if not linked due by cygwin ;) Louis - -- Life
