Bug when changing directory

In WinSCP I was in a directory
/home/user/path/wfdemo
In ssh I did
cd /home/user/path
rm -r wfdemo
Then in WinSCP I tried to change to /home/user/otherpath
and got an error message that it could not change to /home/user/path/wfdemo

It should not try to cd to that when it is trying to do that from there.

Re: Bug when changing directory

What protocol? How exactly did you try to change the directory? Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I'll be able to capture a session log soon, but for now the steps are

I store my connections in KeePass and use the Override URL setting to open WinSCP. Here is that command.
cmd://"WinSCP.exe" /ini="%USERPROFILE%\Documents\Config Files\WinSCP\config.ini" "scp://{USERNAME}:{PASSWORD}@{URL}" -rawsettings  ConsiderDST=2
Once connected I click the button to open a PuTTY session.

In the GUI (Explorer style, not Commander) I select a directory and view contents

In PuTTY I rm -r that directory.

(All of this made sense in context, this is just the pared down version.)

Then in WinSCP I try to click on a directory other than the one I'm in (because it doesn't exist any more)

I tried clicking on the home directory.
I tried going up a directory using the up button in the GUI
I tried clicking on the a different directory.
I tried clicking on the home directory again.

Oh, I found my log file...

Re: Bug when changing directory

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

Downloaded and set up.

I'm trying to set up a minimal test case to reproduce the error in the original WinSCP before doing it again in the debug version.

While I was able to repeat the error originally (as seen in the logs I posted) I am no longer able to repeat the error – I even went back to the original server and deleted the same directory.

Now my tests were short – in my original there were 3 hours from begin session to error. I can set up the debug version to be the default WinSCP for that server and capture the logs.

Where the error happened is a web host shared environment that now reports itself as:
$ lsb_release -d
Description:    Ubuntu 18.04.4 LTS

I have also tried in my home lab:
$ lsb_release -d
Description:    Ubuntu 22.04.3 LTS

I verified that I'm still on the same version of WinSCP as before and that I am using the original config file and command line.

Well, I know how to reproduce the problem. But that scenario is fixed. I was just wondering, if you might have a slightly different scenario, which might not have been fixed yet. If you do not, then it's ok :)

Let me know if you face any problems.
