Gnus v5.4.52; 2.0; nntp 5.0; nnspool 2.0; nnfolder 1.0
GNU Emacs 19.34.1 (i386-debian-linux-gnu, X toolkit) of Sun Mar 16 1997 on depreciation



I followed the instructions for making an nnspool group to read the cache, but
it seems to have trouble reading articles cached from groups that aren't my
primary select method.

Also, there seem to be .overview files in the cache, why does the info file
suggest i use nnspool instead of something could take advantage of the
.overview files like nndir or nnml?


Details of the bug report:

I get the following backtrace if i put a (debug pathname) in
nnspool-request-group: 

("/home/gsstark/News/cache/kaffe/")
  (let ((pathname ...) dir) (debug pathname) (if (not ...) (nnheader-report ... "Invalid group name (no such directory): %s" group) (setq nnspool-current-directory pathname) (nnheader-report ... "Selected group %s" group) (if dont-check ... ... ...)))
  nnspool-request-group("kaffe" "cache" t)
  gnus-request-group("nndsc:kaffe" t)
  gnus-select-newsgroup("nndsc:kaffe" t)
  gnus-summary-read-group-1("nndsc:kaffe" t t nil nil)
  gnus-summary-read-group("nndsc:kaffe" t t nil nil)
  gnus-group-read-group(t t "nndsc:kaffe")
  byte-code("ÀÁ\211\n#\205^I^@\n\207" [gnus-group-read-group t group] 4)
  gnus-group-read-ephemeral-group("nndsc:kaffe" (nnspool "cache" (nnspool-spool-directory "~/News/cache/") (nnspool-nov-directory "~/News/cache/") (nnspool-active-file "~/News/cache/active")) nil (#<buffer *Gnus Browse Server*> . browse))
  gnus-browse-read-group(no)
  gnus-browse-select-group()
* call-interactively(gnus-browse-select-group)

but the actual ~/News/cache directory looks like this:
$ ls -l ~/News/cache
total 6
-rw-r--r--   1 gsstark  gsstark        21 Jun  1 00:44 active
drwxr-xr-x   2 gsstark  gsstark      1024 May 31 14:38 nndsc:Bug_GNU_Emacs
drwxr-xr-x   2 gsstark  gsstark      1024 Jun  1 02:44 nndsc:kaffe


for reference, here is the nnspool:cache server:

(nnspool "cache"
	 (nnspool-spool-directory "~/News/cache/")
	 (nnspool-nov-directory "~/News/cache/")
	 (nnspool-active-file "~/News/cache/active"))

and the ~/News/cache/active file:
nndsc:kaffe 736 61 y

The group name for the cache server group for nndsc:kaffe in the .newsrc.eld
file is: "nnspool+cache:nndsc:kaffe"

nnspool does read overview files.

The problem here is that the group is improperly named.  It should be
called "nnspool+cache:nndsc:kaffe", I think.  Probably.

Ah.  A brain fart in `gnus-group-read-ephemeral-group'.  Possibly
fixed in Gnus 5.4.57.
