Oh, and for those brave souls testing the development Win32 release, you
can either close or minimize the temporary TraceLocks window. I was
having some issues with the scrolling diagnostics (Enables / View Logs /
...) and needed that to help track it down. A short intro to the
functionality might be in order. I'll just copy/paste it into the
release notes later.
The old Enables / Debug Logging option has been substantially enhanced
and brought out for on-line visibility. Debug logs are now separated by
category and will dynamically add themselves to cascading menus under
Enables / Logging and Enables / View Logs. Enables / Logging, if
checked, indicates that the program is buffering diagnostic data in that
particular category. This data will also be going to the
APRSISCE/32.LOG file while enabled. Enables / View Logs brings up a
specific category's window and implicitly enables it as well. Enables /
View Logs / All brings up and enables ALL currently known diagnostic
categories. Categories are dynamic. If no data has ever been logged in
a category, that category will not exist in the menus.
Memory considerations: When a category is enabled, it is buffering text
data in memory for some period of time (to be configurable before
10 minutes) or maximum space usage (also to be configurable, but
currently 512KB). However, the space constraint will be ignored if it
would mean deleting data that is too new (...currently 5 minutes). So,
this will consume more memory than you're used to, but overnight on my
laptop with the full feed, it only grew to 40MB according to Task Manager.
HOWEVER, have a window open is a different story! The scrolling windows
are actually multi-line edit controls (think NotePad) into which the
buffered and new events are inserted. This means that they buffer ALL
events from the time they were opened until they are closed (not
minimized). In that same full-feed instance, overnight the client was
occupying approximately 150MB of RAM. When I closed all of the windows
(particularly Packets), the usage dropped immediately to more typical
levels. So, open the window and minimize it if you want to capture a
lot of history. But if you don't, go ahead and close the window knowing
that when you re-open it, it will have at least the past 5 minutes of
data, provided that you kept the category enabled.
If you try to scroll back an active window, you'll quickly get
frustrated as new data arrives at the bottom and jumps the scrollbar
back down. Simply select some portion of text and new additions are
suspended. They're still buffered and will be inserted when you finally
click somewhere to remove the selection.
Oh, and the Copy menu option doesn't do anything yet. It will
eventually copy the entire window contents to the clipboard. I'm also
planning Save. You can already select a chunk of text, Right Click and
choose Copy to get it into the clipboard if you want.
I'm still working on some additional features, including how to control
which data goes to disk and which doesn't. Right now, I think all
enabled data goes to the APRSISxx.LOG file.
Finally, you'll notice that some categories show up with data even when
they were not enabled. The program considers some data to be especially
pertinent, so it buffers it regardless of the Enable setting. This was
true in the past for the APRSISxx.LOG file with the ***** entries.
