These tests check that both thread-local and global search tagging
operations are race-free. They are currently known-broken because
they aren't race-free.
These queries will match exactly the set of messages currently in the
thread, even if more messages later arrive. Two queries are provided:
one for matched messages and one for unmatched messages.
This can be used to fix race conditions with tagging threads from
search results. While tagging based on a thread: query can affect
messages that arrived after the search, tagging based on stable
queries affects only the messages the user was shown in the search UI.
Since we want clients to be able to depend on the presence of these
queries, this ushers in schema version 2.
(Unfortunately, it's difficult to first demonstrate this problem with
a known-broken test because modern Linux kernels have argument length
limits in the megabytes, which makes Emacs really slow!)
This adds support for passing a string to write to notmuch's stdin to
`notmuch-call-notmuch-process' and `notmuch-call-notmuch-sexp'. Since
this makes both interfaces a little more complicated, it also unifies
their documentation better.
Previously, this was in notmuch.el, but all of the other notmuch call
wrappers were in notmuch-lib.el. Move `notmuch-call-notmuch-process'
to live with its friends. This happens to fix a missing dependency
from notmuch-tag.el, which required notmuch-lib, but not notmuch.
Previously, the CLI would print a deprecation warning if a client
requested any format version other than the current one. However, if
we add fields that are backwards-compatible, but want clients to be
able to depend on, we need to bump the version, but that doesn't make
the older version deprecated.
Hence, separate out the "minimum active" version and only print a
warning for requests below this version number.
Previously, the show schema and the search schema used different
"thread" non-terminals. While these schemata don't interact, this is
still confusing, so rename search's "thread" to "thread_summary". To
further limit confusion, prefix all top-level search non-terminals now
begin with "search_".
There have been some plans for making build incompatible changes to
the library API. This is inconvenient, but it is much more so without
a way to easily conditional build against multiple versions of
notmuch.
The macro has been lifted from glib.
We want to load notmuch-tree when notmuch is loaded, so include it as
a require in notmuch.el. To avoid circular dependency we need to move
one keybinding from notmuch-tree.el to notmuch.el: it makes sense for
it to be defined there anyway.
Since tree is now loaded by default there is no need to print a
message when it is loaded.
There are some crufty declare-functions and requires in notmuch-tree:
since it requires notmuch.el itself this all works but in preparation
for the move to mainline tidy this up.
notmuch-help is in notmuch.el not notmuch-lib.el and this is
incovenient for the way pick/tree uses it. I think lib makes more
sense anyway so move it there.
The extra path component added by the lib is a magic value that the
caller just has to know. This is demonstrated by the current code,
which indeed has "xapian.old" both sides of the interface. Use the
backup path provided by the lib caller verbatim, without adding
anything to it.
It was looking in completely the wrong place for the backup and the
(test) xapian database. Unfortunately test_begin_subtest hides the
relevant errors.
The queries don't really work after a database is closed, and we would
like them to be freed if the database is destroyed.

Rename all the test output files to tree rather than pick, move the
containing directory to a tree.expected-output and fix up the
references in the test.
This changes all the lisp names from pick to tree (variables,
functions etc). It also changes the lisp in the emacs-pick test files
to match the new names.
Previously, when a user fully completed a tag operation, they had to
press space to begin entering another tag operation. This is
different from, say, shell file name completion, which typically
inserts a space after an unambiguous completion under the assumption
that the user will want to enter more input.
This patch tweaks `notmuch-read-tag-changes' to act more like shell
file name completion: after an unambiguous tag completion, it now
inserts a space, ready and waiting for another tagging operation from
the user. This is backwards-compatible with old habits, since there's
no harm in putting an extra space.
Authors and subjects can contain embedded, encoded control characters
like "\n" and "\t" that mess up display. Transform control characters
into spaces everywhere we display them in search and show.
We no longer use this, since we've lifted all interactive behavior to
the appropriate interactive entry points. Because of this,
`notmuch-tag' also no longer needs to return the tag changes list,
since the caller always passes it in.
Currently we support both string and list forms of tag-changes for
historical reasons. This is about to change, so fix pick's tests that
use the legacy string form of tag-changes.
`notmuch-pick-tag' takes a list of tag changes, but
`notmuch-pick-archive-message' passes it a &rest argument. This
happens to work if `notmuch-archive-tags' contains a single tag (which
it usually does), but will break if it does not.
This is similar to the previous commit, but applies to search.
Search is somewhat more complicated because its tagging operations can
also apply to a region. Hence, this lifts interactive prompting into
a helper function. This also takes advantage of the new ability to
provide a prompt to distinguish tagging a single thread from tagging a
region of threads.
This modifies all tagging operations in show to call
`notmuch-read-tag-changes' in their interactive specification to input
tag changes, rather than depending on lower-level functions to prompt
for tag changes regardless of their calling context.
Besides being more Elispy and providing a more consistent programmatic
API, this enables callers to provide two call site-specific pieces of
information: an appropriate prompt, and the set of visible tags. The
prompt lets us differentiate * from +/-. Providing visible tags
enables a more consistent user experience than retrieving the
(potentially different) tags from the database, and avoids a
round-trip to the CLI and database.
This modifies the interface of `notmuch-read-tag-changes' to take an
optional prompt string as well as a list of existing tags instead of a
query. This list of tags is used to populate the tag removal
completions and lets the caller compute these in a more
efficient/consistent manner than performing a potentially large or
complex query. This patch also updates the sole current caller of
`notmuch-read-tag-changes'.
