[-- Attachment #1: Type: text/plain, Size: 1877 bytes --]
The attached patch is a work-in-progress for making sure that all of
Gnus' code only accesses group infos via the relevant macros --
essentially hiding the fact that group infos are implemented as lists,
in anticipation of eventually being able to re-implement them as structs
at some point in the future.
Essentially, "(nth 3 info)" becomes "(gnus-info-marks info)", and so
one.
It also replaces uses of "gnus-info-set-*" with "(setf (gnus-info-* ".
The setter macros aren't deprecated, though.
My main question is about the use of the EXTEND argument to
`gnus-info-set-marks', `gnus-info-set-method', and
`gnus-info-set-params'. In the current patch, I have left the setter
intact wherever the EXTEND argument is passed, until I can figure this
out.
If I could understand why _some_ of the infos are expected to be short a
few elements (newly-created groups?), I would rather provide a
`make-gnus-info' function (again, in anticipation of a struct
constructor), which could be called with the elements of an info (either
as a list or spread) and return an info filled-out with nils where
necessary. Then that could be used wherever we expect a short info.
There's also the weird spot in gnus-sum.el:6183 where we're chopping off
nil elements from the end of an info list, I don't know why.
One last bit I'm uncertain about is in `nnvirtual-request-update-info',
where I've replaced this:
(setcar (cddr info) nnvirtual-mapping-reads)
(if (nthcdr 3 info)
(setcar (nthcdr 3 info) nnvirtual-mapping-marks)
(when nnvirtual-mapping-marks
(setcdr (nthcdr 2 info) (list nnvirtual-mapping-marks))))
with this:
(setf (gnus-info-read info) nnvirtual-mapping-reads)
(when nnvirtual-mapping-marks
(setf (gnus-info-marks info) nnvirtual-mapping-marks))
It seems to work fine, but to be honest I don't really understand the
original logic.
Eric

There's tons of out-of-tree code that would break. Huh, I didn't realize that list-based structs didn't put a tag in the `car' position unless you pass the :named keyword. We could switch to list-based structs without breaking out-of-tree code, but I don't see much point: you can't use them for generic function dispatch, even when they're :named, nor do you get a NAME-p predicate for free. That doesn't leave much point. I think we can just stick with hiding the implementation for now, encourage other developers not to use `nth', and maybe someday in the future switch to record-based structs. >> If I could understand why _some_ of the infos are expected to be short a >> few elements (newly-created groups?), I would rather provide a >> `make-gnus-info' function (again, in anticipation of a struct >> constructor), which could be called with the elements of an info (either >> as a list or spread) and return an info filled-out with nils where >> necessary.

Okay, maybe all that stuff should just stay as it is, then. Alternately, I could do something fancy with gv-setters for `gnus-info-marks' et al, so that setting them via `setf' would first ensure their length. Alternately, we could pad out each info as it is read from .newsrc.eld, and vacuum out nils again before it is written. Then the rest of the code could just forget about it. >> One last bit I'm uncertain about is in `nnvirtual-request-update-info', >> where I've replaced this: >> >> (setcar (cddr info) nnvirtual-mapping-reads) >> (if (nthcdr 3 info) >> (setcar (nthcdr 3 info) nnvirtual-mapping-marks) >> (when nnvirtual-mapping-marks >> (setcdr (nthcdr 2 info) (list nnvirtual-mapping-marks)))) >> >> with this: >> >> (setf (gnus-info-read info) nnvirtual-mapping-reads) >> (when nnvirtual-mapping-marks >> (setf (gnus-info-marks info) nnvirtual-mapping-marks)) >> >> It seems to work fine, but to be honest I don't really understand the >> original logic. > > I don't understand it either, but it's setting both the second and the > fourth slot, isn't it? I'm pretty sure the first line (setting the read slot) is correct. Then the if statement... "if the info has marks or method or params, set the marks to nnvirtual-mapping-marks, regardless of whether nnvirtual-mapping-marks is nil or not, and overwriting whatever the marks were before. Otherwise, if the info has no marks and nnvirtual-mapping-marks is non-nil, set the info marks to nnvirtual-mapping-marks." Nope, still don't get it. It seems to me the only real question is whether or not nnvirtual-mapping-marks should override whatever marks were already there. Eric ^ permalink raw reply [flat|nested] 7+ messages in thread

Okay, here's what the patch looks like now. 1. gnus-info is defined with defstruct, and the constructor arglist looks like: (group rank read &optional marks method params), meaning that if you have an info list that may or may not be fully extended, you can run it through the constructor and all the missing elements will be set to their default (nil). 2. This is done when reading the newsrc.eld file (and creating new groups), and all the other uses of the 'extend argument have been removed.` 3. The bit that chops off nils from the end of infos has been moved from `gnus-update-marks' to `gnus-gnus-to-quick-newsrc-format', so it only happens right at the last minute, when saving. 4. I've changed `gnus-set-info' to update each element of an info individually, rather than just replacing the whole thing. This looks stupid, but preserves object reference, meaning we no longer need to mess with the `gnus-newsrc-alist' in `gnus-group-set-info', which was causing trouble for people. It's going to be a bit slower, but I don't think this is super performance-crucial. I think that's it... This still needs some testing, but I'm optimistic.
