by using direct function pointer it is a little bit faster ;-)

Enough performance testing from my side :-)
Still curious why wrapped call is so slow.

Hello, @dail, @scott-sumner, @claudia-frank, and All,

Ah, I didn’t think that my slowness’s feeling, regarding that script, would lead to so many posts ;-))

I realize that I was quite vague, about the results of the test. So I did, again, the test with both :

Python v1.0.8.0
Lua v0.6.0.0

installed, in a N++ v7.4.2 local configuration, on a old Win XP SP3 platform, with 1Go of RAM, only !

The python test script was :

for line_nbr in range(100, 12400):
    editor.markerAdd(line_nbr, 24)

And the Lua test script was :

for line_nbr = 100, 12400 do
    editor:MarkerAdd(line_nbr, 24)
end

Results if applied on a classical .txt file, containing 12436 lines, with size = 613,527 bytes :

1m and 59s for the Python script
0.5s, approximatively, for the Lua script

Really awesome, isn’t it ?! How to explain such a difference ??

BTW, Dail, I ran the command, below, in the Lua Console. Not sure, however, that it’s the right syntax !

dofile("Dail_Bookmark.lua")

Now, Dail, an other problem !

My first idea, for doing the test, was to install the Lua last version ( 0.7.1.0 ). Unfortunately, when starting N++, I got a tiny window, with the message Unknown exception. After validation, this windows disappeared but the lua plugin was not uploaded ( Quite sure that uploaded is not the right English word but I hope I will be understood ! ) That issue also occurs with the v0.7.0.0 version ! So, the last Lua plugin correct version is v0.6.0.0, on my XP machine.

Probably, this happens on Win WP platforms, exclusively ? But, dail, it’s not that important. Indeed, Don Ho, seemingly, considers not supporting, soon, Win XP, anymore ! Refer :

https://notepad-plus-plus.org/community/topic/15003/notepad-7-5-4-release/26

Nevertheless, thanks, by advance, for any investigation, on that matter !

Best Regards,

guy038

Update :

I’ve just done the test, twice, again, with the Python script ==> A bit better : 1m and 33s , approximatively !!

Some very interesting results for sure, I can’t say much as to why the PythonScript version is so much slower and I am very unfamiliar with the Python/C API. Maybe someone more knowledgeable has some ideas.

Unfortunately, when starting N++, I got a tiny window, with the message Unknown exception.

Sorry to hear the newer versions are not working for you, and I agree it is probably related to Windows XP. Between versions 0.6.0 and 0.7.0 I did update to VS2015 and it also uses a newer runtime. Even though it is suppose to be compatible with XP there still seems to be a problem as you have found out. Personally I do not have access to an XP machine any more so any XP related issues will probably go unfixed unless someone submits a pull request fixing them.

I don’t think file size matters, I did a test with a 100mb file as well as with
file containing just enough carriage returns -> result is the same.

I haven’t found out yet why PythonScript(PS) is so slow in this case and it must be
something how PS handles the wrapped call because when using PS and the
Direct_Function call then I do get results like this

DirectFunction took 0.0729999542236 seconds
DirectFunction took 0.0710000991821 seconds
DirectFunction took 0.0720000267029 seconds

DirectFunction took 0.0729999542236 seconds
DirectFunction took 0.0769999027252 seconds
DirectFunction took 0.0739998817444 seconds

I did some poking around…and installed PythonScript (I haven’t used it in years). When I ran some test code, one of the first things I realized is that it is that Scintilla is being redrawn multiple times when using PythonScript. I verified this by catching the SCN_UPDATEUI event in Lua. The LuaScript call generates 1 event, using PythonScript generates numerous events…not always the same amount (normally about 50% of however many bookmarks were added). It probably also generates numerous SCN_MODIFIED events?

You might try a similar test with PythonScript which doesn’t generate any type of side effect, something simple like SCI_STYLEGETFORE which should be a very fast and simple call.

@dail

thanks for looking into this.
I will give it a try and let you know.

Good job, I guess that is the area which needs investigation, yes.
I tested with synchronous and asynchronous callbacks - result was more or less the same.

If I
added markers for 30 lines it report one aditional updateui event,
adding markers to 290 lines it added 3 additional event
adding markers to 3800 lines it added 40 additional events

lua reported only 1 event in all cases, the same is true if using Direct_Function call.

Hello, @dail,

Did you see that post :

https://notepad-plus-plus.org/community/topic/15089/notepad-file-status-auto-detection-not-working/37

It seems that @vitaliy-dovgan found out a solution, regarding VS2015 and the auto-detection problem, in XP

So, given that information, may be, after few modifications, we could have the Lua v7.0 and Lua v7.1 plugins working nice on XP platforms ? Just an intuition but I hope so !

Cheers,

guy038

Unfortunately I’m not sure if that’s the cause of issues with LuaScript running on XP. I know that the plugin itself doesn’t use that type of function call. I’m not sure if the Lua interpreter does underneath…if so it’s probably not something I care to dig into.
