#5275 closed defect (fixed)

SCI: Bug in file read/write operations

Reported by: OmerMor Owned by: wjp
Priority: normal Component: Engine: SCI
Version: Keywords:
Cc: Game: Hoyle's Classic Card Games

Description

Game version: 2.00/DOS/English ScummVM version: 1.2.0svn52211 Platform: Windows7 32bit

I start a game (crazy eights), select characters (graham, pepper, willy), the game shows a b/w picture and then crashes. The following is printed to the console: picture resource 913 not found!

In DosBox the game works fine so It's not a faulty game.

It seems you got an invalid game.opt file (which contains the game options that the game saves). Search your game folder (game.opt), or your saves folder (hoyle4-game.opt) and rename it, and please attach it to this bug report

Renaming this, it's a general issue with the way we read/write custom game files. Examples are Hoyle 3, Hoyle 4 and Phantasmagoria

I added game.opt (zipped) from the game folder, and hoyle4-game.opt from scummvm save folder. the problem seems to be that both are present. If only one is present the game works. however, if the file is present in the game folder, than the second one is generated by scummvm in the save folder, and next time the game is started the bugs occurs again.

Fixed in rev #52298 (we weren't checking for end of file, or file read errors)

It looks like this may be caused by fgets_wrapper reading 1 byte if maxsize is 1. If I do *dest = 0 in that case instead of readByte(), the string in game.opt seems to be read more sensibly, and the crash is then gone.

(The current behaviour was added in r47575)

After discussing it with thebluegr and m_kiewitz, I've committed this as r52396. Could you verify if that fixes it for you? (I'm leaving comment posting open on this ticket, so you should be able to reply without starting a new ticket this time.)
