lib: migrate from Xapian ValueRangeProcessor to RangeProcessor This will be mandatory as of Xapian 1.5. The API is also more consistent with the FieldProcessor API, which helps code re-use a bit. Note that this switches to using the built-in Xapian support for prefixes on ranges (i.e. deleted code at beginning of ParseTimeRangeProcessor::operator(), added prefix to constructor). Another side effect of the migration is that we are generating smaller queries, using one OP_VALUE_RANGE instead of an AND of two OP_VALUE_* queries.
build: drop support for xapian versions less than 1.4 Xapian 1.4 is over 3 years old now (1.4.0 released 2016-06-24), and 1.2 has been deprecated in Notmuch version 0.27 (2018-06-13). Xapian 1.4 supports compaction, field processors and retry locking; conditionals checking compaction and field processors were removed but user may want to disable retry locking at configure time so it is kept.
lib: run uncrustify This is the result of running $ uncrustify --replace --config ../devel/uncrustify.cfg *.c *.h *.cc in the lib directory
Use https instead of http where possible Many of the external links found in the notmuch source can be resolved using https instead of http. This changeset addresses as many as i could find, without touching the e-mail corpus or expected outputs found in tests.
lib: optionally support single argument date: queries This relies on the FieldProcessor API, which is only present in xapian >= 1.3.
lib: add date range query support Add a custom value range processor to enable date and time searches of the form date:since..until, where "since" and "until" are expressions understood by the previously added date/time parser, to restrict the results to messages within a particular time range (based on the Date: header). If "since" or "until" describes date/time at an accuracy of days or less, the values are rounded according to the accuracy, towards past for "since" and towards future for "until". For example, date:november..yesterday would match from the beginning of November until the end of yesterday. Expressions such as date:today..today means since the beginning of today until the end of today. Open-ended ranges are supported (since Xapian 1.2.1), i.e. you can specify date:..until or date:since.. to not limit the start or end date, respectively. CAVEATS: Xapian does not support spaces in range expressions. You can replace the spaces with '_', or (in most cases) '-', or (in some cases) leave the spaces out altogether. Entering date:expr without ".." (for example date:yesterday) will not work as you might expect. You can achieve the expected result by duplicating the expr both sides of ".." (for example date:yesterday..yesterday). Open-ended ranges won't work with pre-1.2.1 Xapian, but they don't produce an error either. Signed-off-by: Jani Nikula <jani@nikula.org>
