ICEcoder 'locks-up' stops opening files

[jenspr]

DESCRIPTION:

After a while (hours!!) of usage ICECODER (8.0 BETA) seems to lockup. It will not open files anymore when clicking files in the left navigation pane. (see errors below) The onyl workaround I found was to remove it and reinstall it. I guess something locked up :-( Any hint?

WEBSERVER: IIS/Windows BROWSERS: CHrome, Safari

Thanks for the issue report & details, very helpful!

It would seem that when getting the file location for the file you're trying to load (in this case C), it can't seem to figure things out, causing substr('C', 0, false) here and the 3rd param must be an integer, not boolean: https://github.com/icecoder/ICEcoder/blob/8.0beta/classes/File.php#L47

Because the 3rd param on that line: strrpos(str_replace($docRoot, "", $file), "/") is returning false (because it can't find the string reverse position and ICEcoder's code expects a number), it's then causing a 500 error. It's weird you end up needing to reinstall icecoder but I suspect there's a knock-on reason. I've got something slightly wrong here and needs a tweak to always return a number.

Probably because it's an unusually short filename, C - I'll do some tests and see what needs amending.

I can add following feedback. I had experienced the issue on IIS. I workaround the problem by disabling "auto open files" in the settings. My second install was on a Linux powered Webserver (don't know which). There everything worked as expected (=no issue) Hope this helps a bit.

I have the same issue on windows. I don't believe the above example is where the file name is 'C'. That is the hard disk and the rest of the path is missing, i think probably due to the :. Except in my usage i edit files on the F drive and I get this issue too, except where C is the above, F shows.

ICEcoder.previousFiles = ['F:|xampp|htdocs|st|index.php']

The issue can be replicated by a new installation, Opening a file. Refreshing the browser twice, so ICEcoder.previousFiles refreshes with the data, then attempting to open from the recent files.

I think the issue is also impacting indexer.php as this always returns empty Uncaught (in promise) SyntaxError: Unexpected end of JSON input at icecoder.js?microtim…1624619945.7505:163

return response.json();

Thank you both the updates and yeah @StillTravelling - you're right, the cause of the problems is the colon, not a short filename.

The cause was actually this... when you open a file you can optionally specify the line number to jump to if you wish, seperated by colon. ie, you can press CTRL + O and then if you have an /xyz.txt file you can enter /xyz.txt:5 in the popup dialog box and it'll load xyz.txt and set your cursor on line 5 when loaded.

However, the current logic it has re that colon separator doesn't take into account Windows paths which themselves have a colon, so when trying to open a Windows path it'll split C:/some/dir/xyz.txt into 2 parts - thinking C is the file path and /some/dir/xyz.txt is the line number.

I've pushed this commit to add extra logic, to fix that issue: https://github.com/icecoder/ICEcoder/commit/487ce2710cdbd23d246cdbcdefa21eac8d55aa89 (see lines 1993 to 2001).

This appears to fix the problem (I've seen it fixed now when running on XAMPP on Windows) - could you confirm all if OK for you both too?

@StillTravelling - I think the extra issue you noted re indexer is a knock on error. Now the above is fixed, it seems to run fine, let me know if you still see problems there?

[StillTravelling]

@mattpass Looks good now on windows. Can open recent files again once the page is refreshed, so many thanks.

The indexer still returned an empty response, but had a feeling it is actually related to something else. In the /data/index.php file, i can see it's been indexing .ts (media file rather than typescript) files which i think might be stressing the process out a bit. I have now removed ts from $indexableFileExts and it's now returning json data. Not sure this is fixable or worthy of fixing, just one of those things where the file extensions are the same.

[mattpass]

@StillTravelling glad to know the fixed worked.

Ah, didn't even consider file extensions may be used for different purposes, such as .ts. I think a good solution is to check if the file MIME type is "text/*" to avoid looking into binary files such as the media file you mentioned. Have done that in this commit: https://github.com/icecoder/ICEcoder/compare/42d60ea48fdb1a993232ea2685c99548ee1a8007...master

Hopefully you can now undo removing it from $indexableFileExts, pull test latest commits and it'll avoid scanning your .ts media files as they're not text from here on.

@mattpass the indexer works perfectly now thanks to the MIME type addition. Thanks once again.

Excellent, glad all is sorted here, will close issue now. Thanks for the help & feedback. 👍🏼
