Subject: [PATCH 01/10] Clean up file unpack iteration logic a bit

Handle rpmfiNext() in the while-condition directly to make it more like

similar other constructs elsewhere, adjust for the end of iteration

code after the loop. Also take the file index from rpmfiNext() so

we don't need multiple calls to rpmfiFX() later.

Subject: [PATCH 04/10] Upgrade FA_TOUCH to FA_CREATE if the file went away

 (RhBug:1872141)

When %_minimize_writes is enabled, we determine unchanged files during

fingerprinting and only update their metadata (FA_TOUCH) instead of

always recreating from scratch (FA_CREATE) during install. However

package scriptlets (and administrators) can and will do arbitrary stuff

in the meanwhile, such as rm -f their own files in %pre, hoping to

get a fresh copy of contents no matter what. Or something.

Now, if the file was determined to not need changing by rpm, this will

just fail with chown & friends trying to touch non-existent file.

One can consider this a case of package shooting itself in the foot, but

when a package update fails or succeeds depending on %_minimize_writes this

to me suggests the feature is at fault as much as the package.

Do fsmVerify() on all files to be FA_TOUCH'ed to detect files whose

type changed or were removed since fingerprinting. This still doesn't

ensure correctness if something tampers with the contents in the meanwhile,

(for that we'd need to run the file through the whole machinery again,

checksumming and all) but covers the most glaring cases.

Subject: [PATCH 05/10] Refactor file install and remove around a common struct

Collect the common state info into a struct shared by both file install

and remove, update code accordingly. The change looks much more drastic

than it is - it's just adding fp-> prefix to a lot of places.

While we're at it, remember the state data throughout the operation.

No functional changes here, just paving way for the next steps which

will look clearer with these pre-requisites in place.

From 215525131b0e4e015d83c25828700d7531fec6dd Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/10] Refactor fsmMkfile() to take advantage of the new state

 struct

Move setmeta into the struct too (we'll want this later anyhow),

and now we only need to pass the struct to fsmMkfile(). One less

argument to pass around, it has way too many still.

No functional changes.
