XBoard interactive help

[hgm]

OK, I see that too. In fact XBoard is completely dead after closing the help dialog through the window-close button.

Well, I asked Arun to do a development releaseon the current version, so this is something I could still fix before the 4.9.0 release.

[MikeB]

Does XBoard adjudicate that, or does the engine claim it? XBoard has no way to prevent an engine from claiming a draw. If the engine does not want to play, it does not want to play. We could forfeit it for that, but that is probably also not what you want. (And a bit unfair to the engine.)

In other words, the ruleMoves option is an option that controls adjudication by XBoard. The engine doesn't know anything about it. For that, you would need an engine option to set the rule moves. (Fairy-Max actually does have such an option!)

to me it loose like the adapter sent the draw - even though I have the ignore Syzygt50MoveRule unchecked for both engines ( SF vs SF). stockfish log shows no claim of draw. Here is the log snippet for the losing side that would claim draw if it made sense:

Is polyglot claiming the draw ?

[MikeB]

from the readme in polyglot:

Code: Select all

PolyGlot tries to solve known problems with other adapters.  For
instance, it detects and reports draws by fifty-move rule, repetition,
etc ...

s/b fairly simple to edit this out or just make it an option...

[MikeB]

yes , polyglot was the culprit...

unfortunately , I must have fat-fingered something in my xboard setup and now I cannot get the uci options to appear or even load, I had to do it the old fashioned way using polyglot with polyglot.ini as the engine...let me know if you you any tips for fixing xboard in the Mac so I can load ici engines through the GUI

in any event, this was the cursed win I wanted to see played out , without the 50 man rule.. mate in 259.

at move 242. Ng6 , if you play it out with 242 ...Nxg6 it is very instructive on how to trap a knight that is too close to the edge

[d]5R2/4n3/1k2K1N1/5n2/8/8/8/8 b - - 0 1

edit as far this ending being a practical teaching tool - I doubt it. most of the moves were way beyond my comprehension - could not really follow the logic, except i know SF was on a mission to capture the knights and with 6 man EGTB's, it does that quite quickly. The settings here were 10 sec/.17 sec increment

Note that if you want to use a less intrusive adapter (that does not meddle with the game), you could have used UCI2WB instead of Polyglot. That would claim draws only if the engine itself claimed a draw. That would also rid you of rep-draws, illegal-move claims etc.

[hgm]

OK, I see that too. In fact XBoard is completely dead after closing the help dialog through the window-close button.

Well, I asked Arun to do a development releaseon the current version, so this is something I could still fix before the 4.9.0 release.

It seems that bug has always been with us: when you open the Tournament Options dialog and generate an error there (e.g. pressing OK after selecting only a single engine), and then close the Error Popup through its window-close button, you cannot close Tournament Options either. (Help / Note / Error all use the same dialog.) We just never noticed it, because there aren't too many dialogs where you can generate Error Popups.

The culprit is that the handler for the GTK popdown signal (be it the Cancel button or window close) contains an explicit test for whether there is an Error Popup open, and ignores the signal when it is. It tests this based on errorDialog global variable, which is set when the Error dialog pops up, and cleared when you hit the OK button. (In XBoard's dialog system every dialog can define such an 'OK function', which takes care of any post-processing needed by the altered values in the dialog. But we hve no corresponding dialog-dependent 'Cancel functions'; it isassumed that Cancel always is a simple popdown.)

The logical solution would be to forbid popdown of the Error dialog through the window-close button altogether. (For this reason the Error dialog also has no Cancel button.) In the case of Help this seems very undesirable, though, as the help text could be so long that the OK button is off-screen.

I guess I could hard-code in the GenericPopDown handler of the GTK signal that in the case of ErrorDlg it should not call the normal PopDown function, but the specific ErrorPopDown (which then calls the normal PopDown after clearing the errorDialog flag, and is also used by other events, such as board clicks, that should pop down the Error dialog). This makes task-specific code leak into the generic dialog handling, but I guess we can live with that for now.

[JoshPettus]

Great that works! Nice to find old bugs

Unfortunately it still looks like MANDIR is still hard coded. Once I move the app, it can't find the man page. I'm still trying to figure out why.
{EDIT}
I just did a test using manDir variable to locate the man file in the applescript line for manProc. It found the man file no matter where the app was. So manDir variable works. Did we use the manDir variable when executing help clicks? I don't see that in DisplayHelp() (not that it's defined in dialog.c anyway) But somehow assigning manDir to MANDIR isn't working out. Is it because we did that before manDir got a value?

[hgm]

Oh, ^@$*^%^(&%. I guess that the redefinition of MANDIR is only valid in xoptions.c, not in dialogs.c.

[JoshPettus]

I was afraid you'd say that...

[hgm]

Searching for DATADIR revealed that it is also used in usystem.c, for expanding the ~~/ in filename options. So the same problem should exist there.

I guess I should just move the declaration variables dataDir and manDir to dialogs.h, and statically initialize them to DATADIR or MANDIR, (and overwrite that in the OSX-specific startup code), and then use the variables everywhere, even in the non-OSX version.
