Subject: lei q: importing messages when specifying '-f *json*'?
Date: Thu, 30 Dec 2021 18:04:23 -0500

The lei-q interface I'm working on for piem [1] consumes JSON output to
display search results.  From there, an individual message can be shown.
If the query is against a remote external, that involves two curl calls
to the remote, one for the search and one for the display.

I'd like to import hits from the first step into the local store so that
I can avoid the second curl call.  However, I haven't been able to
figure out a way to do this when requesting JSON output.

For example [2], say I don't have meta's 20211124154539.350522-1-e@80x24.org
locally:

  $ lei daemon-kill
  $ export HOME=$(mktemp -d "${TMPDIR:-/tmp}"/pi-testing-XXXXXXX)
  $ lei q m:20211124154539.350522-1-e@80x24.org
  # /tmp/pi-testing-3JaSz2K/.config/lei/config created
  [null]

If I search for that message against https://public-inbox.org/meta/ and
request JSON output

  $ lei q -I https://public-inbox.org/meta/ -f ldjson \
    m:20211124154539.350522-1-e@80x24.org
  # /usr/bin/curl -Sf -s -d '' https://public-inbox.org/meta/?x=m&q=m%3A20211124154539.350522-1-e%4080x24.org
  {"blob":"a8754283bd9e985d6e1156215071be59aa2b5a53",...}

then no message ends up in the local store:

  $ lei q m:20211124154539.350522-1-e@80x24.org
  [null]

In contrast, if I request mboxrd output

  $ lei q -I https://public-inbox.org/meta/ -f mboxrd \
    m:20211124154539.350522-1-e@80x24.org >/dev/null
  # /usr/bin/curl -Sf -s -d '' https://public-inbox.org/meta/?x=m&q=m%3A20211124154539.350522-1-e%4080x24.org

the message is imported to the local store:

  $ lei q -f ldjson m:20211124154539.350522-1-e@80x24.org
  {"blob":"a8754283bd9e985d6e1156215071be59aa2b5a53",...}
  $ git -C $HOME/.local/share/lei/store/local/0.git/ log --oneline
  ca12a1b (HEAD -> master) [PATCH] eliminate some unused subs

I was hoping that --import-remote might do the trick, but that doesn't
seem to be the case:

  $ lei daemon-kill
  $ export HOME=$(mktemp -d "${TMPDIR:-/tmp}"/pi-testing-XXXXXXX)
  $ lei q --import-remote -I https://public-inbox.org/meta/ \
    -f ldjson m:20211124154539.350522-1-e@80x24.org
  # /tmp/pi-testing-Ny7KDcB/.config/lei/config created
  # /usr/bin/curl -Sf -s -d '' https://public-inbox.org/meta/?x=m&q=m%3A20211124154539.350522-1-e%4080x24.org
  {"blob":"a8754283bd9e985d6e1156215071be59aa2b5a53",...}
  $ lei q m:20211124154539.350522-1-e@80x24.org
  [null]

Should --import-remote trigger an import in the case above?
