RE: File disappears after cffile rename
Hi Michael, Apparently on CF8, if the cffile.serverfile name and the newly assigned name var are the same, the file will get deleted when it fires the cffile rename. I tried this simple code and wasn't able to reproduce this issue. cffile action=RENAME source=C:\temp1.txt destination=C:\temp1.txt The file temp1.txt wasn't deleted. Am I missing something? Please let me know. If it is a bug, we need to fix it.

RE: File disappears after cffile rename
On a side note, I can't think of a reason you would want to use a named lock, but use a random name every time. Since the point of a named lock is to make sure only one thread at a time can execute the code inside cflocks of the same name; generating locks with random names seems pointless since no two locks would ever have anything to wait on. If you want to keep two pages from writing to the same file or directory at the same time, use the full file path or directory path as the lock name. ~Brad -Original Message- From: Michael E.

RE: File disappears after cffile rename
cflock name=#CreateUUID()# type=exclusive timeout=30 throwontimeout=no cfset PAGE_clean_SERVERFILE = replace(cffile.SERVERFILE, , _, all) cffile action=RENAME source=cffile.SERVERFILE# destination=#PAGE_clean_SERVERFILE# /cflock Firstly, the CFLOCK as you have it is pointless. Using a CreateUUID() function to name a lock simply creates a lock that is uniquely named and offers no protection to the code running inside. Your mileage may vary if you call the lock name fileUpload or if you need more granularity, #cffile.serverfile#. Next, I'm not sure if the code you've entered is a copy paste or a retype (I'm assuming a re-type) because you have an error in the cffile tag call. Source should have a # before the cffile. Thirdly, it would help if we could see your CFFILE action=upload call that actually uploads the file to your server so we can determine what the filename is going to be, eg as you uploaded it or, uniquely renamed by CF as part of the upload process.

RE: File disappears after cffile rename
Hi, Michael... I've used cffile many times to upload documents, but never to rename them, so I'm speaking from a lack of experience. However, looking at the documentation, I see that the source is a full local system path with the filename, and the destination is also a full local system path, including the new name of the file. While the paths can be absolute or relative, it seems from your code below that neither the source nor the destination is a path. Also, you might try putting cfoutput#PAGE_clean_SERVERFILE#/cfoutput cfabort after the cfset statement to make sure your file renaming to eliminate spaces is producing the desired name. One last thing...I just noticed that you've got only 1 # around cffile.SERVERFILE in your cffile statement. Is that in your source, also? Rick -Original Message- From: Michael E.

RE: File disappears after cffile rename
Issue solved. (Or perhaps a CF8 bug) On: cfset PAGE_clean_SERVERFILE = replace(cffile.SERVERFILE, ,_,all) cffile action=RENAME source=#cffile.SERVERFILE# destination=#PAGE_clean_SERVERFILE# Apparently on CF8, if the cffile.serverfile name and the newly assigned name var are the same, the file will get deleted when it fires the cffile rename. To fix it, I wrote a compare() between the 2 names: if its different, on then will it execute the cffile rename. I didn't have to do this on CF7 and below. Hth someone else in the future.

RE: File disappears after cffile rename
@ Paul, Rick, and Brad: Thanks a bunch for your comments, ideas, suggestions. The reason why I had the cflock was because directly after the cffile rename, was a cfexecute for ffmpeg. Without the lock, it seemed that ffmpeg begins to execute even before the actual file rename on the file system completes. Ffmpeg then throws an error because it does not allow file names with spaces. You're talking milliseconds of overlap here- unsure if its caused by the server OS latency but as far as CF goes, I think it thinks has completed rename. It doesn't seem to happen all the time, but I did see it happen. The lock just seemed to prevent that from happening. -Original Message- From: Michael E.

RE: File disappears after cffile rename
Claude, I am sure you (et al) are right on the use(lessness) of locks in this case. As I said, I used it with uncertainty thinking (hoping?) that it was preventing an overlapping of execution between the file rename and cfexecute. In other blog threads, I found quite a number of posts about cffile and ffmpeg, and how both can co-exists but don't really sync well together. Circling back to the original cffile renaming-disappearing issue, at least that is resolved. -Original Message- From: Claude Schneegans [mailto:[EMAIL PROTECTED] Sent: Thursday, October 18, 2007 3:19 PM To: CF-Talk Subject: Re: File disappears after cffile rename The lock just seemed to prevent that from happening.
