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.
