Files are deleted from the data server's upload and download directories
|
||
|
|
by the <b>file_deleter</b> daemon.
|
||
|
|
Typically you don't need to customize this.
|
||
|
|
The default file deletion policy is:
|
||
|
|
<ul>
|
||
|
|
<li> A workunit's input files are deleted when
|
||
|
|
all results are 'over' (reported or timed out)
|
||
|
|
and the workunit is assimilated.
|
||
|
|
<li> A result's output files are deleted
|
||
|
|
after the workunit is assimilated.
|
||
|
|
The canonical result is handled differently,
|
||
|
|
since its output files may be needed to validate
|
||
|
|
results that are reported after assimilation;
|
||
|
|
hence its files are deleted only all results are over,
|
||
|
|
and all successful results have been validated.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
In some cases you may not want files to be deleted.
|
||
|
|
There are two ways to accomplish this:
|
||
|
|
<ul>
|
||
|
|
<li> Run the file_deleter daemon with
|
||
|
|
the -preserve_wu_files command-line option
|
||
|
|
(to preserve all input files)
|
||
|
|
and/or the -preserve_result_files command-line option
|
||
|
|
(to preserve all output files).
|
||
|
|
<li> Include <no_delete/>
|
||
|
|
in the <a href=files.php><file_info></a> element for a file in a
|
||
|
|
<a href=tools_work.php>workunit or result template</a>.
|
||
|
|
This lets you suppress deletion on a file-by-file basis.
|
||
|
|
|
||
|
|
</ul>
|
||
|
|
In either case you may need to implement your
|
||
|
|
own scheme for deleting files,
|
||
|
|
to avoid overflowing data server storage.
