When I download a file from a directory on tahoe-lafs via 'tahoe get', then I only get "retrieve" and "mapupdate" entries on the "Recent Uploads and Download" page. I'm having this issue in a simple setup within one VM host, one node dedicated as a storage node, one as a dedicated gateway node.

Could be related to #1079.

Example "Recent Uploads and Download" page output:

Is it a mutable or immutable file that you are downloading from the directory?

$ ./tahoe list-aliases -d ~/.tahoe-2
> tahoe: URI:DIR2:...

And as I'm always using the alias 'tahoe' for any 'tahoe put' or 'tahoe get', I guess it's a mutable directory/file.

Okay, after the IRC discussion the download entry now appears on the status page. It turned out that I was "uploading" a very small file (19B) only with a LIT capability. So previously the 'tahoe put' returned:

200 OK
URI:LIT:...

Now with a slightly larger file (95B) I get the following response and the download is listed on the web page as expected:

200 OK
URI:CHK:...

I didn't know or expect that very small files would be treated differently somehow - or that if so this would be transparent to the user :).

So I guess the solution to close this ticket is to add a legend and "help text" or a hyperlink to a document so that users can discover and learn what the "Recent Uploads and Downloads" page really shows.

updating title to match, and recording some thoughts..

I can't decide if I want the legend to be between the "current ops" and "recent ops" sections, or at the bottom after "recent ops". It should probably be in a smaller font. I don't want to have to scroll down to see the first 4 or 5 items in the list. It should probably teach the following lessons:

immutable files are marked as "upload" (copied into grid to servers) and "download" (copied from grid from servers)
reading a mutable file does a "mapupdate MODE_READ" followed by a "retrieve"
creating a new mutable file does a "publish"
modifying an existing mutable file does a "mapupdate MODE_WRITE", then a "retrieve", then a "publish"
small immutable files (below about 65 bytes) are stored as LIT filecaps and do not appear on this list at all
directories are usually stored in mutable files, so directory changes will appear as mutable-file modifications

warner changed title from ~~download of file into dir doesn't appear on Recent Uploads and Download~~ to add legend to Recent Uploads and Downloads page, explain LIT

If the legend is at the bottom, there should be an intra-page link to it at the top.
