Bill Currie	9a92496662	[console] Don't overwrite tail line if same as current line ... This fixes the current line object getting corrupted by the tail line update when the buffer is filled with a single line. There are probably more tests to write and bugs to fix :)	2022-09-17 13:56:23 +09:00
Bill Currie	d13df6cd37	[console] Add failing unit test for con_buffer ... I was looking through the code for Con_BufferAddText trying to figure out what it was doing (answer: ring buffer for both text and lines) and got suspicious about its handling of the line objects. I decided an automated test was in order. It turns out I was right: filling the buffer with a single long line causes the tail line to trample the current line, setting its pointer and length to 0 when the final character is put in the buffer.	2022-09-17 12:59:36 +09:00
