I can open files larger than 500MB just fine in Geany on my 4GB Linux laptop, (albiet with nothing else running, @AdamDanischewski close your browser :). It takes about 6 secs to open or to move the cursor to the end of the file. That seems ok for 1/2 GB file on a laptop. Scintilla uses two bytes of memory for each byte in the file, plus some for each line, so memory usage is at least double the file size and more is needed during opening to handle encoding conversions and UTF-8 validation. As soon as the file is big enough that memory usage reaches 4GB, it causes swapping and it looks like it froze, but in fact it will come back after a time, its just that swapping to disk is slooooow. Of course if you fill up swap all bets are off :)
@hdaz000700 Operations like copy and paste result in several copies in memory at once, reaching the limit of memory faster than the file itself does, and so starting swapping and so appearing to freeze sooner. So if you are copying and pasting large amounts its not the same as opening the file. This is made worse if the encoding of the material on the clipboard needs to be changed as thats another copy again. None of the above is a surprise, exceeding memory is not a bug or issue we can do anything about. @hdaz000700 What is interesting is the confused display shown in your screenshots where the end of line characters are not at the ends of the lines. That indicates that something else is going on as well. Thats what I'm trying to investigate, as it may indicate a bug that may be making your problem worse. So for the moment all I'm interested in is if the file opens correctly in Geany and Scite, Linux and Windows. Then we can look for causes if the file opens ok, taking it one step at a time to prevent getting confused again. -- You are receiving this because you are subscribed to this thread.
