Transformer to purge temporary files

Hi,

 

 

I don't think there is such a transformer.

 

FME itself has a functionality to delete automatically temp files after completion of a translation. And I don't think that the size of temp files affects so much to performance of the translation, unless overflowing disk size.

 

So I don't worry about that.

 

 

This article may be helpful.

 

Why did the temporary files not get deleted from my translation? (http://fmepedia.safe.com/articles/FAQ/Why-did-the-temporary-files-not-get-deleted-from-my-translation)

This is a shutdown script example to try removing all the temporary files and folders in the FME_TEMP folder.

 

I cannot guarantee that it always works safely.

# Shutdown Python Script Example

 

import os

 

 

# Try removing a file/directory specified by the path.

 

# If the path indicates a directory, it removes recursively

 

# all subdirectories and files under the directory.

 

def rmfile(path):

 

    if os.path.isfile(path):

 

        try:

 

            os.remove(path)

 

        except:

 

            pass

 

    else:

 

        map(rmfile, ['%s/%s' % (path, f) for f in os.listdir(path)])

 

        try:

 

            os.rmdir(path)

 

        except:

 

            pass

 

 

# Get FME_TEMP directory path from environment variable.

 

# If it exists, try removing all temporary files and folders.

 

tmp = os.environ.get('FME_TEMP')

 

if tmp != None:

 

    map(rmfile, ['%s/%s' % (tmp, f) for f  in os.listdir(tmp)])

Tcl too can do that concisely.

# Shutdown Tcl Script Example

 

proc rmfile {path} {

 

    if {[file isdirectory $path]} {

 

        foreach f [glob -directory $path -type {f d} *] {rmfile $f}

 

    }

 

    catch {file delete $path}

 

}

 

 

if {![catch {set tmp $env(FME_TEMP)}]} {

 

    foreach f [glob -directory $tmp -type {f d} *] {rmfile $f}

 

}
