| Mod-Player: HippoPlayer 2.46beta|
After 21 years today Kari-Pekka Koljonen has released an update of his MOD player HippoPlayer on Github. He wrote:
"There was an actual user request (by daxb) in the English Amiga Board a few years back to remove the module list size restriction. This turned out to be a fun challenge. The code assumed the module list index to be a positive 16-bit number, and also used the same index with some magic values to mean a few things. There were a lot of places to change to make this work. The restriction is now at 0x1ffff (131071), which is a crazy amount.
Such a large list eats a lot of memory and is quite slow to process, as it is a doubly linked list. List iteration operations needed some optimization to be usable on an A500. (Next challenge: get rid of the linked list approach.) Random play bookkeeping previously worked only for lists of up to 8192 (0x1fff) modules, this limit is now removed as well.
I decided to challenge myself with some UI changes. The main window buttons are quite cryptic with both left and right mouse button actions, which I have conveniently forgot about. I implemented a modern feeling tooltip which will pop up a helpful text for each button. Maybe this is a first tooltip on kick1.3?
Right clicks on the buttons don't really work like left clicks. I don't know why the past-me left them like that, they're ugly and non-user friendly that way. I changed the buttons to have a proper visualization for right clicks as well.
I also added a few wait pointers to places with long running operations.
Another thing that motivated me to do some hippo coding was the realization that the multitasking approaches used in HiP are bad. At the time I had no idea about thread safe programming. This could lead to some random crashes at times due to bad luck with timing.
Exec provides semaphores to protect shared data, so these were added to a lot of places. Some safety regarging interrupts relying on some data was also added. External applications using the HippoPort still use all data freely.
