[7.55pß1] Crash on view from external sync

[Flint]

I opened an external Sync Dirs, compares two RAR archives by contents — one file was present only on the left side. I pressed F3 on it (it was an HTML file and opened in Lister with the HtmlView plugin). After I closed the Lister, TC crashed with the following message:

Code: Select all

Thanks for your report, I will check it.

Please report crashes by e-mail. It makes no sense to report them in the forum because
- normally other users cannot reproduce them
- those who report them can usually not reproduce them either
- there is nothing to discuss

Thanks!

Then you should add some text in the popup like:
"Please send this error report to this [Email]."

Perhaps you should also to add an "email" button to automatically open the email program. Or add an "report to author" button that does it automatically.

I'm using a standard MessageBox here because at the moment of the crash, it's possible/probable that more complex dialog will not work.

[Samuel]

I know about this, so I suggested to add the text.
Perhaps you could open another window afterwards capable to send the report. (If it doesnt open still the msgbox opens.)

I will keep that in mind. However, reproducability of this particular problem is 100% on two my computers (XP and XP x64).

In public beta 2 it is still there, BTW.

[ghisler(Author)]

Sorry, I cannot reproduce it. Do you get it also with a fresh wincmd.ini (no Lister plugins)?

No, HTMLView must be installed. Here is the minimal INI with which I can reproduce the problem:

Code: Select all

[ListerPlugins]
0=%COMMANDER_PATH%\Plugins\Lister Plugins\HTMLView\HTMLView.wlx

Of course, it could be a problem in the plugin, but it did not crash in earlier TC versions. I now checked early betas and found that the problem appeared in private beta 3 (beta 2 does not crash, beta 3 does).

[ghisler(Author)]

Thanks for the info. I'm still using IEview here, not HtmlView - so far no crashes. Can you try whether you get it also with Ieview? If yes, it may depend on what HTML files exactly you are trying to view.

[Flint]

Can you try whether you get it also with Ieview?

I tried with IEView 1.94a — no crash.

BTW, I found another prerequisite: the Lister should be closed with Esc. If I close it using the [X] titlebar button, or by menu File->Close, TC does not crash.

I uploaded the two test archives here:
http://flint-inc.ru/Temp/tcbeta75/syn2.b185.rar
http://flint-inc.ru/Temp/tcbeta75/syn2.b185a.rar

My scenario:

1. Start TC using the following command line:

TOTALCMD.EXE /S=S "E:\Temp\syn2.b185a.rar" "E:\Temp\syn2.b185.rar" /i=.\test.ini

test.ini contents:

Code: Select all

[Configuration]
SyncFlags=1
[ListerPlugins]
0=%COMMANDER_PATH%\Plugins\Lister Plugins\HTMLView\htmlview.wlx

(I'm using comparing subdirs here only to see the HTML files in comparison results; if you repack the RAR placing a HTML file in the root, the bug is reproducable even without SyncFlags option.)

2. Press Compare.

3. Select any of the HTML files.

4. Press F3.

5. Press Esc.

6. TC crashes.

[ghisler(Author)]

OK, I will test with HtmlView.

This error should no longer occur with beta 3, please test!

Cannot confirm. Here it still crashes on the steps I provided in my previous post. Crash message:

Unfortunately I can no longer reproduce this error, I tried really many times. Please see my e-mail to you for a possible solution.

Just for the record: the bug was reproduced only in multi-monitor configurations and was finally fixed in 7.55rc1.
