jCommander / Bugs / #101 [win32] Cannot open tabs when home directory is the root

Based on a short analysis, it seems that the way we build up
the default directory name does not work when the user's
home directory is the root drive on Windows. The resulting
Commons VFS URL is not valid (e.g. "file://D:") and should
rather be "file://D:/". A small thing, indeed, but it is
enough for it not to work.

Unfortunately it is quite hard for me to reproduce this bug,
but I would welcome your input on this.

I have provided a fix for what I think the problem is.
Please see this lates development build if this fixes the
problem:

Can you confirm that the bug is fixed?

Thanks for looking into this, its partialy working now.
When I start the app, I get the error message box(with not
caption) with a message:
Badly formed URI "D:".
After clicking OK, the window is empty.
However, clicking the button to open a new tab does open a
new tab with name: Tab 0 [file:///D://][file:///D://]
Bit too many "/" but I can now browse the file system.

Keep up the good work!

OK, this is better. Do you still get the initial error
message after the first successful startup of JCommander?

I get the error only when jCommander starts with no tabs.
That is at the very first time or after I have closed all
the tabs and exited and started it again.

I also find the root element of the directory tree very
confusing. The menu "Partitions" in the tab has my disks
named properly, the drive letters with the volume labels,
but the root of the directory tree is always this ugly label:
file:///D://
Can it be simply D:\ or D: or D: with the volume label?

As a first step please try to delete the jcommander.conf
file from your home directory (D:). I would consider this
bug fixed only when everything works perfectly.

Regarding your thoughts on the user friendliness of VFS
URLs, you're quite right. Based on this, I have created and
implemented this feature request: 1465312 "Display user
friendly VFS URLs"

This feature also fixes a big problem with the display of
the passwords in clear text.

Please see the latest development build at
http://prdownloads.sourceforge.net/jcommander/jcmd-0.7.1-20060405.zip?download
and please let me know the remaining issues.

Sorry for taking this long to respond, I've been quite busy
at work with no time to test jCommander. Until now.
I've installed(unzipped) the 20060405 version, deleted the
configuration file and after starting the jCommander I still
got the same "Badly formed URI D:" message.
After that, the window has not tabs. Opening a new tab shows
me the listing of drive D: and everything seems ok.

Almost everything.
I accidentaly opened a directory that has 4000(four
thousand) files and that has rendered the jCommander
unsable(the system has slowed down as well). Even after few
minutes, the jCommander still shows "receiving content of
directory" and the CPU jumps to 100%. The CPU usage goes
down after few seconds after I switch to another application
but jumps back to 100% when I switch back(and it is still
receiving content of the directory). For comparison, another
"native" file browser takes few seconds (less than 5) and
Windows Explorer shows the directory almost instantly.

Thanks for taking your time to help out with this problem!

I have uploaded a development version with more verbose
logging (link to the win32 package):
http://prdownloads.sourceforge.net/jcommander/jcommander-0.7.1-win32-20060425.zip?download.
I would like to ask to you to once more delete the
configuration file, start up JCommander so that the error
appears and post here the relevant parts of the log.

Regarding the performance bottleneck, yes, we know about it.
For us the performance benchmark on Windows is the
Windows/System32 folder which contains thousands of file. We
realise that there's a problem going on, but we haven't
really had the time to deal with this optimisation so far.
In any case, thanks for reminding us about it.

Disconsider the previous link and please test with this

I have tried with the latest version as well with the one
previously suggested and in both cases the result is the
same, an error message saying: Badly formed URI "D:" .
Below is the content of the log files and conf files for
both versions I've tried with.
