- Subject: Faircoms c-tree™ with MacApp 2.0ß9
-
- Hi fellow MacApp'ers,
- has anybody used the B-Tree/ISAM package c-tree™ from Faircom Corporation in
- conjunction with MacApp 2.0ß9 ?
- We are using it and have stumbled across some (minor) problems:
-
- 1) When c-tree sends a request to the server (via AppleTalk), it waits for the
- answer in a tight loop calling GetNextEvent on each pass through (File:
- ctamsg.c, Function: at_ask). This, apart from not being fully compatible with
- Multifinder, obstructs the busycursor mechanism of MacApp and should interfere
- with idle processing. Does anybody have a solution for this ?
-
- 2) When running a debug version, I crash unpredictably about >50% of the time
- after quitting the App. Seems to be something like an async request floating
- around without any handler when the app is gone !??
-
- 3) Is there a clean way to do some cleanup when leaving the App regardless of
- the way we're leaving ? When leaving via Quit menu, TApplication.Terminate
- should do the job, but what about leaving via Quit in the debug window ? In
- this case TApplication.Terminate isn't called. Do I have to patch ExitToShell ?
-
- Apart from these problems, c-tree seems like a great allaround DB System: fast,
- flexible and 'cause source comes with the package extendable.
-
- Just for the record: I'm using a Mac IIx with 8MB Ram, System D-6.0.4, MPW 3.1,
- MacApp 2.0ß9, c-tree V4.3 Release C, some inits including SetSelfSend cdev and
- others like Responder using AppleTalk.
-
- Any answers are welcome
-
