Load First Engine exits

[Brian Richardson]

I'm trying the Winboard-AA package (so as not to use Polyglot for UCI), and am having trouble. On Win7Pro, when I click the ... entry to pick a new engine to create in Winboard, it just exits (before the file selector screen appears). I have tried from an administrator cmd (thinking it might be some permission issue) and there is no information. Debug file below. I was able to get one new engine loaded, but I cannot load any new engines anymore. I don't recall exactly what I did such that it worked the one time.
Thanks,
Brian

PS I tried the Edit Engine List option but it throws the changes away. Edit is never highlighted and not clear what Save and OK should do. I am reluctant to edit the wb_engines.dat file

Hmm, yes, I sometimes have that too. The crash seems to happen inside the file-browse popup, which is in MicroSoft code, not WinBoard code. That is not to blame MicroSoft; it could of course be that I am calling it with invalid parameters, e.g. a pointer that would cause a segfault when it tries to use it. It just means that it is hard to debug with my usual method of putting printf's in the code. I scrutinized the parameters with which I launch the file-browse dialog, and superficially there doesn't seem anything wrong with them.

Strange thing is that it only happens occasionally, and then usually goes away when you use the file browser for another purpose, e.g. load a PGN file.

[Brian Richardson]

Thanks for the reply.

I just tried starting Winboard-AA and using both File Load Game and Position it exits immediately.

Version 4.7.3a works fine getting to the file selector screen. Perhaps something changed?

Regards,
Brian

[H.G.Muller]

Well, that is the amazing thing. Nothing was changed in the code relating to this file browsing; it has been there for ages. Suddenly it started doing this, and only on rare occasions. (But once it happens, it is not so easy to make it go away.) Does it also crash when you try to open the browse dialog for saving something?

The Edit-Engine list is a general edit dialog also used for editing tags and book and such. I think it is always in edit mode; that the Edit button is shown is probably a legacy / bug. I think I just forgot to remove it. (Originally there were two 'tags' dialogs, one for editing, and one for just viewing, but the one for viewing contained an Edit button, which would pop it down, and would pop the editable one up. But these dialogs looked identical.)

'Save' commits the changes you made in the text widget to WinBoard's internal settings. This is the same as 'OK', except that the latter also closes the dialog. (Which is fine for editing the engine list, but was very annoying when editing book.) In older WinBoards the engine list was in the regular settings file, and this was only written when you have 'Save Settings on Exit' on. If it was off, (and you don't force saving through 'Save Settings Now'), what you committed to WinBoard internal engine list would not make it to the settings file.

This latest WinBoard can save the engine list in a separate file, but I cannot recall how exactly I implemented this. It would make sense if it wrote that file immediately when you press 'Save' in the edit dialog; one of the reasons to introduce it in the first place must have been to be able to save the engine list without saving other settings.

[Brian Richardson]

OK, I think I have found at least part of the problem.

I tried doing a Save Position and it exited immediately.

Then, just for whatever, I tried specifying the Just view or edit games option, thinking there might be some delayed problem with the engines already in the Specify Chess Engines 1 and 2 on the first page or in the engines list.

Of course, that works (at least as far as a file selector dialog). But the odd thing, is that loading the first engine in the list worked just fine.
It still does not work without the Just view or edit option.

Brian

Update: Using the Just view option above I was able to add an engine to the list. When restarting and picking that engine, it works. The problem has something to do with the Stockfish V engine that happens to be in the first position in my engine list and is the default in the first page engine 1 and 2 options.
