Error "Could not find file" when using dump methods

[mamoschli]

As stated in #58 (comment) we are currently running into issues when using getSQLDump or getFilesDump.

The backup task does work and the correct dump file is saved on the source. What doesn't work is downloading the file, instead we see this error:

fab config:stage getSQLDump

Done.
Disconnecting from some-host.com... done.

While the backup task was running I listed the directory contents of the tmp folder and for a split second the file was there, then it got removed by Fabalicious. Do you have any idea why this might happen?

This was tested using the master and develop branch (including the fix from #58), but the results were the same.

Thanks for your help.

Fabalicious will delete the file after it downloaded to the host -- any chance there's something cleaning the /tmp-folder? Have you tried setting a different tmp-folder?

[mamoschli]

I tried a different folder (which is possible thanks to your fix in #58 🙂 ) but the result was the same. We used the methods on other hosts and they work just fine. Using these method is not important in this environment, I just thought it would be good to report this as it might be a bug in Fabalicious or Fabric... of course it's possible that this is some fancy behavior of the server...

hmm, strange. We use getSQLDump quite often and the same code-path is used when running copyDBFrom which is used on a daily base on various hosting platforms.

Does fab config:some-host.com getFile:someFile.ext work?
