Best practices - file sizes? CF Builder limit

[coder1957**]

Is there a practical limit to file sizes?

Specifically .cfc. 

My entire application is using ajax saving, URL free screen rendering and I have 3 or 4 cfc's ... but each one is growing to over 5,000 lines of code.

Is there a limit to file sizes?  To what CFBuilder can handle.  I see CFBuilder slowing down.

I realize, of course, that CFC's never leave the server but still ...

As far as I know, there is no straightforward answer to the question of maximum file-size for the ColdFusion Builder 2018 editor. Nevertheless I can aim for a good guess.

ColdFusion Builder's settings are stored in the configuration file located at {CFBUILDER_INSTALLATION_DIRECTORY}/CFBuilder.ini. For example, on my installation of ColdFusion Builder 2018, the configuration file is C:\ColdFusionBuilder2018\CFBuilder.ini. Its contents are:

-startup

plugins/org.eclipse.equinox.launcher_1.5.100.v20180827-1352.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.800.v20180827-1352

-vmargs

-Xmx1024m

-Xms64m

-XX:MetaspaceSize=32m

-XX:MaxMetaspaceSize=256m

-Djava.net.preferIPv4Stack=true

-Duser.language=en

-Duser.country=US

-Dfile.encoding=UTF-8

This shows at once that Builder is a Java application based on Eclipse software. So I searched on the web for information about file-size limit in Eclipse. I discovered there is no limit.

Therefore my guess will only depend on Builder being a Java application. Furthermore, as the setting -Xmx determines the maximum working memory of a Java application, I shall consider it to determine the absolute maximum file-size.

But the software has other tasks to perform. Hence my guess that

       maximum file-size = (1/10)th of the Xmx value

In my case, this would be

        maximum file-size = (1/10) x 1024 MB = 102 MB

Well, last year using the immediate previous version of CFBuilder, I had it constantly crash with these (5000 line)  files.

I also had it often, when opening a file that was already open, it would load two copies.

With the latest version,  04 February 2019, 02:53:05  3.2.1 I have found a practical limit of 7,600 lines.

It constantly times out with a spinning cursor.  Then the entire screen goes "pale"; which with the old version would then crash.

This one seems to recover.

So I have added some includes ... that seems to be a workaround.

I think size matters in this case. The size of the file, that is, what else?

[coder1957**]

Sorry, that was not the most sensible comment I made ... lines!

The file size is 277k

For laughs I have just opened a file of close to 100 000 lines (21 MB) in CFBuilder 2018. It lasted a blink.

[coder1957**]

Not following your vernacular?  Blink?

Translate that into British English? 

You mean Builder perished?

[BKBK]

Ha ha, you got me there. I now see the double-entendre. (In any dialect of English, incidentally). By "it lasted a blink" I meant "opening the file lasted a blink" (good), not "Builder lasted a blink" (bad).

Thanks for your remark.

There are plenty of practical limits to file sizes, all along the way from writing to execution. At one point, there was a maximum Java class file size. I don't know if that's still a potential issue. I would strongly recommend that you have several smaller files instead of one large file, as it'll generally make it easier for you to write and manage that code.
