Dokan driver should allow zero-lengths as they are used in some programs. 

ReadFile on NTFS handles them fine, just returning success.

I agree with you that create file should throw an error saying "file not 
found". But if this is case then move file will not work at all on dokan. 
I think dokan create file function should call move file when second file 
is not present and opened in open mode. am i missing something? sorry to 
reopen the issue. please help me. i need it.

Currently Dokan does not provide a nice way to have several filesystems in
one process. I propose the following changes:

1) Add a 'GlobalContext' in the DOKAN_OPTIONS structure.
2) Make Dokan to pass this context to each callback in DOKAN_FILE_INFO
structure in a new 'GlobalContext' field.

want to ensure CreateFile is called after Cleanup for each file

There appears to be no pre-built versions of Dokan that supports the 64-bit
versions of Windows XP and Windows 2003.

Adding support for these versions of Windows would allow Dokan (and
subsequently the user-space drivers utilizing Dokan) to be highly
distributable across all of the currently used Windows distributions.

What steps will reproduce the problem?
1. execute move/rename command on command prompt to move or rename the file
2.
3.

What is the expected output? What do you see instead?
rename of file or movement of file from one location to another


What version of the product are you using? On what operating system?
dokan 0.2.0 and windows server 2008. 


Please provide any additional information below.
whenever i execute move or rename command on command prompt (move/rename 
first.txt second.txt), first call goes to dokan createfile function and 
not to move file function. Create file tries to open second file 
(second.txt) and it doesnot get it and create file function throws an 
error saying file(second.txt) not found. why this is so?

What steps will reproduce the problem?
1. Call CreateFile with TRUNCATE_EXISTING creation disposition on a dokan 
mounted drive
2. Observe flags coming in from dokan CreateFile callback, creation 
disposition is 3 (OPEN_EXISTING)
3.

What is the expected output? What do you see instead?
Expected: creationDisposition = 5 (OPEN_EXISTING)
Actual: creationDisposition = 3 (OPEN_EXISTING)

What version of the product are you using? On what operating system?
Dokan: 0.3.7
OS: Windows XP Home SP3

Please provide any additional information below.

Cache manager support in kernel mode

What is the expected output? What do you see instead?

This doesn't break any functionality, but it is recommended to close any 
SC_HANDLE with CloseServiceHandle, not CloseHandle.

There are at least 6 occurrences in mount.c, which should be corrected.


What version of the product are you using? On what operating system?

Windows XP SP3, dokan 0.3.9

Please provide any additional information below.

What steps will reproduce the problem?
1. Call CreateFile on a dokan mounted drive with CREATE_NEW and 
FILE_FLAG_DELETE_ON_CLOSE 
2. Observe flags and attributes passed to dokan driver CreateFile callback: 
set to 0
3. Call CloseHandle on handle returned by CreateFile in step 1. Expect file 
to get deleted (which it isn't)

What is the expected output? What do you see instead?
Expected: Flags and attributes set to (0x04000000) FILE_FLAG_DELETE_ON_CLOSE 
Actual: Flags and attributes are set to 0

What version of the product are you using? On what operating system?
Dokan: 0.3.7
OS: Windows XP Home SP3

Please provide any additional information below.

DokanSSH symbolic support

What steps will reproduce the problem?
1. Run "mirror.exe"
2. Create a single file or folder on dokan drive
3. Try to delete file in file explorer

What is the expected output? What do you see instead?

Expected is not to get any error message. Instead I see the following 
error:

---------------------------
Error Deleting File or Folder
---------------------------
Cannot delete hello: Cannot find the specified file.

Make sure you specify the correct path and file  name.

OS : WinXP SP3

Please provide any additional information below.
I'm using a private key file (generated using Puttygen), which works fine
in Putty.

add timezone setting for timestamp of file

What steps will reproduce the problem?
1. Call CreateFile on a dokan mounted drive with GENERIC_READ and or 
GENERIC_WRITE set for the "dwDesiredAccess" argument
2. Observe how the CreateFile dokan driver callback provides a seemingly 
bogus value of 1245599 (0x13019F).
3.
#define GENERIC_READ    0x80000000
#define GENERIC_WRITE   0x40000000

What is the expected output? What do you see instead?
Expected: Correct values for dwDesiredAccess when using CreateFile
Actual: What seems like a random value

What version of the product are you using? On what operating system?
Dokan: 0.3.7
OS: Windows XP Home SP3

Please provide any additional information below.
This is likely not only an issue with GENERIC_READ and _WRITE but probably 
any other flag used to define the access mode.

We should be able to handle both case-senstive and case-insenstive 
comparison when searching FCB in kernel.

What steps will reproduce the problem?
1. I am using Dokan.NET 0.2.0 in windows 2008.
2. In function GetFileInformation, i update the values like create
   time,access time and modified time of out parameter(i.e. FileInformation
   fileinfo) with my own informations, the values i updated are not 
   reflected on windows application.
3. If i retrieve the informations from applications like explorer, command 
   prompt , it gives current system date and time for create, access and 
   modified time.


What is the expected output? What do you see instead?
Value of access,create n modified should have the values i gave and not the 
current system time.


What version of the product are you using? On what operating system?
Dokan-0391191x86, Dokan.NET 0.2.0 in windows 2008.


Please provide any additional information below.

Its a c# code
In GetFileInformation function

/* code snipet */
fileinfo.CreationTime = DateTime.FromFileTime(value from my source);
fileinfo.LastAccessTime = DateTime.FromFileTime(value frm my source);
fileinfo.LastWriteTime = DateTime.FromFileTime(value from my source);

Value from my source is of type long(64 bit).

Well the thing is that i have debugged my code and checked if the values
are properly assigned and i found that fileinfo.CreationTime,
fileinfo.LastAccessTime and fileinfo.LastWriteTime has the values that i
have assigned. So i suppose that it should reflect the values i assigned
when retrieved from windows applications like explorer(right-click n click
property), command prompt etc. but it gives current date and time only.



i tried with the sample code you distributed “DokanNetMirror” in which u
mounted a local drive through dokan, and even in this case, it does not
reflect the values i gave to creation, access and modified time.

/* here is the code snippet */

FileInfo f = new FileInfo(path);
DateTime d1;
long tim;
tim = 128687193710000000; /* Hard coded value i gave */
d1 = DateTime.FromFileTime(tim);
fileinfo.Attributes = f.Attributes;
fileinfo.CreationTime = d1;
fileinfo.LastAccessTime = d1;
fileinfo.LastWriteTime = d1;
fileinfo.Length = f.Length;
return 0;

The hard coded value is 10/17/2008 5:46:11pm and it properly gets stored in
fileinfo.CreationTime, fileinfo.LastAccessTime and fileinfo.LastWriteTime.
but when i retrieve these informations through explorer and command prompt
it gives the actual time of the file and not the one i have provided.

 When I start the mirror.exe ,when I create a new doc file and edit/save it

What version of the product are you using? On what operating system?
0.4.2, WinXP SP3.

Please provide any additional information below.
I suggest you to test "dokan" by creating a "C# Windows Application" 
project on mounted driver. Then save and run the application through 
visual studio.
Trust me ;)

I think it would be very useful to have support for the extended flags 
available with LockFileEx. LOCKFILE_FAIL_IMMEDIATELY in particular is 
important to implement try-lock semantics.

We should use hash table or tree to look up FCB in kernel.
We may be able to use RtlInitializeGenericTable.

I would suggest to create a simple test suite for Dokan. The mirror 
application doesn't actually check or report any problems but it could 
probably be extended to do so.

The suite could start out with a few basic cases, which test file creation 
and deletion. As users report new issues, new cases could be written, which 
detect those issues. That way Dokan will become more stable and reliable 
with each version and it will be possible to provide users eventually with 
a strong tool to validate their driver implementations.

* I don't know it is a bug or the code is not programmed.

What steps will reproduce the problem?
1. Create a folder on mounted drive and create another one into last 
created folder
2. delete first created folder
3. refresh mounted drive

What is the expected output? What do you see instead?
folders are still available

What steps will reproduce the problem?
Install microsoft office (vers 03 or 07) to a drive that is a SSHFS mount
using dokanSSH

What is the expected output? What do you see instead?
Installation of the Microsoft Office (tried '03 and '07 versions).
What I see is that the installation fails, particularly when copying the
MSOCache files to the SSHFS mountpoint(drive).

What version of the product are you using? On what operating system?
Library: dokan-0.3.9.1191 x86 2008/9/28
SSHFS: dokan-sshfs-0.1.9.1124 2008/6/10

Please provide any additional information below.
Microsoft office installation fails and complains of missing files.
Office installation process failed to copy the MSOCache files and the
installation would not continue.

Office installs to other local drives(C:\ etc). The SSHFS mount has
rw-access and other apps do install to it.

Seems that dokan is doing something that is preventing the office
installation. Any inputs would be appreciated.

What steps will reproduce the problem?
1. Install Dokan driver
2. Run mirror.exe
3. Hibernate and wake up the system

What is the expected output? What do you see instead?
Dokan driver hangs, mirror.exe process can't be terminated. Dokan
stops responding to any user FS activity.

What version of the product are you using? On what operating system?
0.4.0.1223

It would be nice to have hooks available for the Dokan callback threads, 
which get called right after a thread has been created and just before it 
is exiting.

There are several setup and cleanup activities an application might want to 
perform whenever a callback thread is started or is exiting.

One example would be: If Dokan is used with Java through JNI one has to 
attach each thread that wants to perform any JNI invocations to the JVM. 
With these hooks in place attaching and detaching can happen once (when the 
thread is starting and existing respectively) and not with each callback 
(as it is currently done by JDokan), which can negatively impact 
performance.

I have already made some modifications to the dokan code to allow for that 
(based on 0.3.7). The files attached to this report contain the few changes 
I had to make. Obviously the final versions do not have to look exactly 
like that but it might give whoever is looking at this case a better idea 
what I mean.

All changes have a comment section such as the following to clearly mark 
them:

/**
 * Added by Andreas Schuler:
 */

The DokanSSHFS utility is absolutely wonderful and extremely fast.

But it would sure be nice if I could use command line parameters or 
something so I can script Dokan to auto-mount my drives when wndows 
starts, without the annoying settings dialog.

What steps will reproduce the problem?
1. install dokan lib
2. install dokan sshfs
3. connect to server

What is the expected output? What do you see instead?
I'd expect it to connect to server, but it doesn't; the connection doesn't
even start.

What version of the product are you using? On what operating system?
- Windows Vista X86_64 SP1 + all updates at 02/DEC/2008

Please provide any additional information below.
I have and Ubuntu Server and a Vista Client. I've setup the server to
accept only public key authentication with strong encryption, and I made
with puttygen an aes256-cbc key (I am able to connect correctly with
putty+pageant).
I suspect the problem lies on the SharpSSH C# library, or its lack of
support for such kind of encryption.
For what I can tell, I seem to understand that SharpSSH is based on JSch. I
went on the JSch website and saw that there is support for aes256-cbc, but
it seems that SharpSSH has not been updated instead.

TIA for every response and sorry if that's the wrong place, but I really
wanna try dokan!

1. Run mirror.exe at any folder as any drive
2. Open a *.txt file in notepad.exe
3. Wait

<B>What is the expected output? What do you see instead?</B>

It just takes much longer to read in notepad.exe then using 'type' from the
command prompt or notepad++.

I read some where that notepad.exe uses memmapping when openning files. I
was also reading up on why there is CleanUp and Close (cacheing), and saw
the calls CcFlushCache, CcPurgeCacheSection and CcUninitializeCacheMap in
DokanCompleteCleanup. Comment out these calls and recompiling solves the
problem. Notepad.exe reads files suddenly at the speed you would expect.
I'm guessing that what needs to happen is these three calls need to happen
only when the last reference to the file is released so that IRP_MJ_CLOSE
is forced. I'm looking further into this but I thought I should log where I am.

What steps will reproduce the problem?
1. Install driver using dokanctl
2. Uninstall driver
3. Re-install driver

What is the expected output? What do you see instead?

Dokanctl fails to re-install the driver. I know that this is mentioned in 
the readme (so this can be considered an enhancement request), but I would 
like to understand why. The starting of the driver seems to be failing with 
a code 2 (file not found). It would be nice if the driver could be updated 
without requiring a system reboot. From an end-user perspective this would 
be a very desirable feature.

Please provide any additional information below.

If you try to upload any files or folders larger than 10/20 Gigabytes I get
an error that there is not enough space on the available drive (which is
not true). The "Dokan" drive though does say "10 GB free of 20 GB" (my
drive is 500 GB). Is there a way to either set the ACTUAL space or possibly
more space than the actual so I do not get this error?

Thanks,

I think the best way to test the dokan is creating a windows application 
project with C# on created drive with mirror.exe and click to run the 
application from visual studio.

When trying to do a SetEndOfFile that goes beyond the current EOF, Dokan
doesn't pass through the call to the implementation's SetEndOfFile (line 51
of dokan/setfile.c,
http://www.google.com/codesearch/p?hl=de#ER2YZypmdXg/trunk/dokan/setfile.c&q=han
dle%20package:http://dokan\.googlecode\.com&l=45).


Comment:
I guess you found some issues in just passing through this call to the
implementation's SetEndOfFile, did you? But from my experience, handling
the EOF and extending the file's allocation for any access beyond it (write
or truncate) is the file system's business.

Currently Dokan filesystems can be mounted only as root disks. 

It makes to sense to add support for mounting volumes into arbitrary
directories, like in Unix. Windows supports this using reparse points.

What steps will reproduce the problem?
1. run net monitor and mount a path that contains a visual C# project
2. open project from mounted drive
3. open and close a .cs file in Visual Studio environment.

What is the expected output? What do you see instead?
SYSTEM NO LONGER WORKS and will hang.

What version of the product are you using? On what operating system?
0.3.9.1191

Please provide any additional information below.
I think there is a loop not closed.

A CreateFile( ... GENERIC_READ ) is incorrectly mapped to access mode
GENERIC_READ|GENERIC_WRITE. 

This is with Windows XP. Dokan 0.3.9

Error during multiple files deletion

What steps will reproduce the problem?
1. Mount a directory with a couple of files as a drive using mirror.exe
2. Open task manager and look for mirror.exe, leave the window visible so
that you can see the memory usage of the process
3. Open the mirrored drive in windows explorer, position on a file and
check the properties of it
4. You will see the mirror.exe memory usage is growing by about 1M.
Repeating step 3. will continue to increase the memory usage.  

What version of the product are you using? On what operating system?
dokan-0.3.7.1181, Windows XP sp2

Please provide any additional information below.
This behaviour can also be seen in Total Commander and Alpap Salamander,
where it has more serous impact on memory usage. These file managers are
dumping the memory usage by about 10 megs (with 500 files in the mirrored
directory) by just listing the mount point. I think this happens because
these programs request all the file attributes for generating a directory
listing, while explorer only requests this information on explicit user
action (properties dialog). I might be wrong though.

This can be reproduced with sshfs as well. 

ACL support

What steps will reproduce the problem?
1. Open connection with DokanSSHFS.
2. Open a file in emacs using DokanSSHFS. Write "hello hello\n\n", save,
delete to "hello", save, expand to "hello hello\n\n", save, delete to
"hello", save.
3. Close file, clear DokanSSHFS on containing directory, reopen file. 

What is the expected output? What do you see instead?
Shows "hello\nello\n\n\n" instead of "hello" (or maybe "hello\n" 'cause
it's emacs).

What version of the product are you using? On what operating system?
2008-06-10 modified version? Windows XP SP3.

Please provide any additional information below.

What steps will reproduce the problem?
1. I installed dokan-0401223x86 (successfully) on Win XP.
2. Extract dokan-sshfs-0201226.zip into a temporary directory.
3. I run the DokanSSHFSInstall executable and accept the default settings.

What is the expected output? What do you see instead?
I expect DokanSSHFS to install successfully.  Instead, when the progress
bar is at about 95%, a pop-up window appears with the following text:

There is a problem with this Windows installer package.  A program run as
part of the setup did not finish as expected.  Contact your support
personnel or package vendor.

When I click OK to dismiss this pop-up window, DokanSSHFS uninstalls all of
the files that it installed and displays the following text:

The installer was interrupted before DokanSSHFS could be installed.  You
need to restart the installer to try again.  Click "Close" to exit.
