crash while previewing changes

Posts: 3 · redtech116 25 May 2011, 23:40

v. 3.17
win 7 pro x64
when i set up to mirror 2 different folders to a mapped network drive, it does
the compare (80,000+ files)
when i scroll down using the scroll bar, I get to about the mid 400's files
windows kicks out a message saying the program has crashed.
in the event viewer it say event ID: 1000

any ideas.

(when i don't scroll the preview it mirrors the file fine)

Can you give me more details, like what type of mapped network drive are you
using (some cloud provider?) and provide steps how I can reproduce this
problem?

Is there a "LastError.txt" file in the directory containing "lastrun.ffs_gui"
and "globalsettings.xml"?

Additionally: Maybe this crash is not arbitrary, but happens on a particular
file? If so, is there something strange with its metadata, file modification
date or its icon?

It happened to me, too.
Win7 64bit
With 3.16 fine. After migration to 3.17 crash.
System crashes when I compare a local folder to a network folder with nearly
100.000 files.
Network folder is on a video player/network driver appliance with samba
running on it.

Can you answer all or some of the questions above? In order to diagnose the
problem I need more information.

I confirm the crash is not occasional.
I could not find any of the files "LastError.txt" "lastrun.ffs_gui" and
"globalsettings.xml" with Win 7 search

> I could not find any of the files with Win 7 search
Can you directly look in %appdata%\FreeFileSync if you are using the local
installation and "<install dir>" if you use the portal installation?

>System crashe ... samba running on it.
Just tested SAMBA but couldn't find an issue about it. There was however a
problem when setting the input path, which I've fixed. At which point exactly
do you see the crash?

OK, I found the two files in "lastrun.ffs_gui" and "globalsettings.xml" in
"lastrun.ffs_gui" and "globalsettings.xml".

Probably, my problem was in some corrupted files. I confronted the two
directories with Freecommander and I noticed a strange result, some like blank
rows (but it did not crash). So, I manually overwrote part of my archive
(mp3s) and the problem disappeared: no more crashes with Freefilesync 3.17.

Anyway, the crash happened during the confronting phase. I could not find any
"LastError.txt" files, probably because your program polishes that file after
a positively ended run.

Sorry if I made you waste some time.
Great piece of software.

It's not that it deletes this file, but it's not created on every crash. Only
if the crash is caused by an uncaught exception.

> I manually overwrote part of my archive (mp3s)
FreeFileSync should never crash no matter how messed up the input data. If you
can find a way to find out what kind of files or invalid data caused this, I
would like to know.

could not find an lasterror.txt file
only thing i could find was the windows event view item

Okay, these crash dumps don't really help.

Can you identify a single file which makes the app crash when displayed? Or is
it random?

here is a lasterror.txt
Conversion error: SYSTEMTIME -> local SYSTEMTIME: (UTC <strike>: 910692730085
UTC System time: 30828 9 14 2 48 5)

Windows Error Code 87: The parameter is incorrect. </strike>

> 30828 9 14 2 48 5
This means you have a file with modification time
year: 30828
month: 9
date: 14
hour:2
minute: 48
second: 5

FFS crashing is a clear proof Windows is not year-30828 ready :D

Result:
We have two bugs:
1. one of your file's has a corrupted modification time
2. FFS shouldn't crash on invalid file dates

2 -> fixed for next release. I was throwing an exception if number formatting
fails. No idea what I was thinking!

Here's a link to the 32-bit binary for testing:
