The contacts half of the rule that shipped for events, and only the half that
can be decided. A vCard carries a UID its author meant, so a card whose UID
this book already holds is that card, and re-importing an export left a second
copy of every one of them. Reported on #174 by the reporter's colleague, and
decided on #173: skip on a UID that is already here, import what arrives
without one, since nothing can be matched on an identity that is not there.
LDIF is deliberately untouched and now says so in the type. Mozilla's schema
defines no UID and the dn is not an identity outside the directory it came
from, so the import invents a UID that can never match one already present.
Guessing instead from a name and an address is the open question on #223, and
a guess that merges two people who share a name is worse than a duplicate
somebody can see and delete.
Both imports answer with the same shape, so a caller does not have to know
which one it called. LDIF's skipped is always 0, which is the honest number
rather than a missing field.
The UIDs are asked of the server rather than read from the cards in the store.
The store's copy is complete once the view has loaded, and importing does not
wait for a view.
Two callers, two messages. The contacts import reports both counts, as the
calendar import does: "Imported 3 contacts" over a file of two hundred reads
as a failure when the rest were already here. And a vCard attached to a
message -- usually one you have been sent before -- now says it is already in
your contacts rather than reporting that it added none.
Refs #223; the LDIF half stays open.
The same bug the calendar import had, in the three places contacts write
more than one card at once. ContactCard/set is refused whole over
maxObjectsInSet -- requestTooLarge, nothing created -- so a large enough
vCard or LDIF file imported nothing, and "select all, delete" over a large
address book deleted nothing and reported it in JMAP's words.
Nobody has hit it. It was found by looking, after #215 fixed the calendar,
and it is promised on #173.
Both imports now go through one createCards, which splits by the ceiling the
session advertises and falls back to 500. That is what the LDIF import's
comment -- "from ContactCard/set down they are the same" -- was already
claiming, and is now true of.
destroyCards splits the same way, and takes off the list the ids the server
said it destroyed rather than everything that was asked for. It removed all
of them before, which was harmless while there was one call and wrong the
moment a later batch can fail: deleted contacts must not stay on screen, and
live ones must not disappear from it.
One behaviour change beyond the batching. A vCard import the server accepted
no card of returned 0, and the view reported importing no contacts -- which
reads as an empty file rather than as a refusal. It now says why, which is
what the LDIF import has always done. A file with genuinely nothing in it
still says so, earlier and separately.
