Single-threaded is the build-default, and seems to work well enough for
1.12.7, so remove the option to turn it off.
This is because build-options that influence such low-level/core
behavior are a pain to maintain.
Try to avoid multi-threaded operations with Xapian.
This remove the thread workers during indexing, and avoids the indexing
background thread. So, mu4e has to wait once again during indexing.
We can improve upon that, but first we need to know if it avoids the
problem of issue #2756.
Instead of handling transactions in the store, handle it in xapian-db.
Make the code a bit more natural / cleaner-out
Handle transaction automatically (with a batch-size) and add some RAII
Transaction object, which makes all database interaction transactable
for the duration. So, no more need for explicit parameters to
add_message while indexing.
- get an updated maildir list after indexing
- add mu4e-added items to the list opportunistically
Remove mu4e-clear-caches / mu4e-cache-maildir-list to mu4e-obsolete.el
Fixes#2537.
When passing messages to mu, often we got a (parsed from string)
message-sexp from the message document; then appended some more
properties ("build_message_sexp").
Instead, we can do it in terms of the strings; this is _a little_
inelegant, but also much faster; compare:
(base)
[mu4e] Found 500 matching messages; 0 hidden; search: 1298.0 ms (2.60 ms/msg); render: 642.1 ms (1.28 ms/msg)
(with temp-file optimization (earlier commit)
[mu4e] Found 500 matching messages; 0 hidden; search: 1152.7 ms (2.31 ms/msg); render: 270.1 ms (0.54 ms/msg)
(with temp file optimize _and_ the string opt (this commit)
[mu4e] Found 500 matching messages; 0 hidden; search: 266.0 ms (0.53 ms/msg); render: 199.7 ms (0.40 ms/msg)
It can be faster to feed big mu -> mu4e data, such as contacts are
message headers through a temp-file instead directly though stdout;
implement this, and add the server parameter --allow-temp-file.
Implement this the "contacts" and "find" commands.
Without this patch, I see the following error:
;; mu> (move :docid 1 :maildir "/.Archive")
[2b](:error 32818 :message "invalid flags ''")
flags should not default to "", which is not a valid flags string.
Instead of being part of the ping command, create a separate
queries command, which is easier for updating. Ie. 'ping' implies "show
main screen" but we don't always want that side-effect.
