... as otherwise these messages would be just lost.
the assumption is that opposite-side trashing is used only for locally
generated messages whose size we control. it's also more consistent with
same-side trashing, where even oversized messages would be trashed.
the exclusion was broken anyway, as we failed to query the size of old
messages, particularly after 70bad661.
messages for which only a placeholder was propagated should be treated
as not propagated, as otherwise the actual contents will be lost when
only not propagated messages are trashed.
amends 70bad661.
this is a lot more legible, and makes it possible to insert values in
the middle without churn.
i didn't find a way to do this with the pre-processor, so we now have
another code generator.
we now use the $< make variable, which requires gmake on netbsd < 9.0,
and possibly other systems with an ancient make.
this makes config+data file "sets" relocatable, which is useful for
testing.
this is technically a gratuitous backwards incompatible behavior
change, but to the degree that anyone uses relative paths at all, they
almost certainly rely on PWD being set up such that they won't see a
difference.
there are fallbacks to the old locations for compatibility.
the new locations use "isync" instead of "mbsync", which is preparation
for renaming the executable back in v1.6.
- wrap flow-controlled statements that contain blocks into blocks
themselves
- wrap bodies of do-while()s into blocks
- use braces on 'else' symmetrically (this obviously has a cascading
effect, so this patch touches lots of lines)
- attach braces
unavoidably, the rules are sometimes broken around #ifdef-ery.
instead of specifying the mailboxes and sync state verbatim, use a
format which deals only with "subjects" (but no UIDs), and specifies the
whole state for each subject on a single line (exceptions prove the
rule).
the dumpers don't try to re-create the abstraction, as that's deemed
to be an unreasonable effort.
while rewriting most of the test data anyway, move it to the bottom of
the file, which is a more natural location for it.
don't abort the comparison if continuing makes sense, and try to be more
specific about the problems.
we give up if messages are excessive/missing or the subject is wrong,
as that touches upon the rather complex problem of diff optimization.
this avoids the ugly and error-prone repeated reading of the state
after a failure.
cmpbox() had to be made non-destructive on the box state.
readchan() had to be created.
parse the test data into hierarchical structures instead of using it in
its raw form. this is semantically cleaner and allows us to change the
input format more easily.
it doesn't really add any value when resuming after an interruption, as
incomplete propagations are perfectly expected, and are recovered from.
but it does make sense in the non-UIDPLUS path, where not finding just
stored messages indicates a problem.
so move the reporting from match_tuids() to msgs_found_new(), and remove
a redundant warning from the latter.
amends 6577bf3e.
