Hi,

I noticie that when I write to a contact with large log file, there is an important lag (about 1-2 seconds for 5 Mb log).

An strace of psi show me that psi is reading the whole history file before appending the text. It is not happening for each
line appended, but only when the file decscripor of log is closed.


I'm using psi-0.9.3 and qt-3.3.4

Same happens on Windows. History is a subject of rewrite in one of upcoming Psi versions. Hope it will be fixed then.

I think mblsha or IceRAM made some minor changes that might have affected this behavior.  Does the issue exist in the same way on CVS?

History? Me? Never.

I only found some memory leaks (pointers which were never freed) in the events handling system which were patched by Remko (the pointers reffered to events not being freed after they have been added to queue, AFAIR - some users reported big memory usage for Psi and I located the problem in that part of code).

Other than that, nobody touched history/events (fixing bugs/adding features) for the last few versions - AFAIK.

IMO, appending should be done by seeking to the end of file (not reading the entire file) and writing the text there. It's pretty weird it happens the way rusty reported. I have never looked over that code (not mine) since it was marked as "obsolete" and will be revamped in a future version (note that I am not a dev).
