Issue with double spaces in filenames

[Jace Coleman]

I believe that I may have found a bug when it comes to double spaces in fileNames.  I'm on a windows server using Lucee 4.5.1.024.  When i use cffile to upload a document that contains a double space in the filename the file is written to the server with the double space in tact.  However file.serverfile appears to have trimmed the filename and outputs a single space which is resulting in a file not found error.  I wrote the following test code and confirmed the same issue in cfDirectory:

My filename is: 'test  file.pdf'

<cfdirectory directory="/secure/test/doubleSpace/" name="getFiles">

<cfdump var="#getFiles#">

Which outputs:

Query Execution Time: 0.436 ms  Record Count: 2  Cached: No  Lazy: No
	name	size	type	dateLastModified	attributes	mode	directory
1	index.cfm	117	File	{ts '2015-11-05 21:59:28'}			C:\inetpub\wwwroot\application\secure\test\doubleSpace
2	test file.pdf	83699	File	{ts '2015-11-05 21:57:30'}			C:\inetpub\wwwroot\application\secure\test\doubleSpace

Note the double space in my fileName and the single space in getFiles.name

Any suggestions to work around this?  I have also confirmed the same issue exists in the latest version of Railo.

Thanks!

Ok, but how is Lucee finding "test  file.pdf" to output it in that dump? Where's the file not found error? To me, <cfdirectory> seems to have found the file.

How do you know there is a single space in the getFiles.name result? (Perhaps you could test the length of the file name using len() and see if it is shorter than expected.)

Len() outputs 14 just as one would expect with the double space, even though the dump only shows 13 characters and one space.   I need to be able to retrieve an accurate file name via cffile in order to provide a link to the file that was uploaded by a user.

Unless you can demonstrate otherwise, I'm under the impression that the file name is correct, but is simply being rendered in the browser as having only one space. See the following:

We ran into the same issue. Lucee preserves multiple spaces in the filename when saving the actual file but in the filename return variables it combines multiple spaces into one. I'm going to submit a bug in their issue tracker if I don't already see one.

Nando,

• you can view source on his included dump table html to see that there is truly once space and not html combining them.
  
• cfdirectory can "find" it because it isn't looking for a particular file, it's looking for a folder and looping through all files in the folder and returning the results ... incorrectly for the name attribute since it's combining spaces
  
• his len() example is obviously before html has any part in this

[Jace Coleman]

I was actually able to resolve this and at least in my case Nando was correct.  If I recall correctly my problem was that I was uploading the file asynchronsly and then using JS to update a form field containing the file name then submitting the form.

And you are not using the "suppress whitespace" option in the admin?

Kind regards,

Paul Klinkenberg
