lib: migrate from Xapian ValueRangeProcessor to RangeProcessor

2020-07-11T20:20:09Z

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

2020-04-24T00:28:45Z

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

2019-06-14T10:41:27Z

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

2016-06-05T11:32:17Z

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

2016-05-08T11:17:07Z

This relies on the FieldProcessor API, which is only present in xapian >= 1.3.

lib: add support for date:..! to mean date:..

2015-09-26T00:55:24Z

It doesn't seem likely we can support simple date: expanding to date:.. any time soon. (This can be done with a future version of Xapian, or with a custom query query parser.) In the mean time, provide shorthand date:..! to mean the same. This is useful, as the expansion takes place before interpetation, and we can use, for example, date:yesterday..! to match from beginning of yesterday to end of yesterday. Idea from Mark Walters .

lib: add date range query support

2012-10-31T19:55:32Z

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
