[PATCH 1/1] Store and search for canonical Unicode text [WIP]
Rob Browning
rlb at defaultvalue.org
Sun Aug 30 09:21:16 PDT 2015
WARNING: this version is very preliminary, and might eat your data.
Unicode has multiple sequences representing what should normally be
considered the same text. For example here's a combining Á and a
noncombining Á.
Depending on the way you view this, you may or may not see a
difference, but the former is the canonical form, and is represented
by two Unicode code points: a capital A (U+0041) followed by a
"combining acute accent" (U+0301); the latter is the single code
point (U+00C1), which is probably what most people would type.
Before this change, notmuch would index two strings that differ only
with respect to canonicalization, like tóken and tóken, as separate
terms, even though they may be visually indistinguishable, and do (for
most purposes) represent the same text. After indexing, searching for
one would not find the other, and which one you present to notmuch
when you search depends on your tools. See test/T570-normalization.sh
for a working example.
Since we're talking about differing representations that one wouldn't
normally want to distinguish, this patch unifies the various
representations by converting all incoming text to its canonical form
before indexing, and canonicalizing all query strings.
Up to now, notmuch has let Xapian handle converting the incoming bytes
to UTF-8. Xapian treats any byte sequence as UTF-8, and interprets
any invalid UTF-8 bytes as Latin-1. This patch maintains the existing
behavior (excepting the new canonicalization) by using Xapian's
Utf8Iterator to handle the initial Unicode character parsing.
Note that the parsing approach in this patch is not particularly
efficient, both because it traverses the incoming bytes three times:
- once to determine how long the input is (currently the iterator
can't directly handle null terminated char*'s),
- once to determine how long the final UTF-8 allocation needs to
be,
- and once for the conversion.
And because when the input is already UTF-8, it just blindly converts
from UTF-8 to Unicode code points, and then back to UTF-8 (after
canonicalization), during each pass. There are certainly
opportunities to optimize, though it may be worth discussing the
detection of data encodings more broadly first.
FIXME: document current encoding behavior clearly in
new/insert/search-terms.
FIXME: what about existing indexed text?
---
Posted for preliminary discussion, and as a milestone (it appears to
mostly work now). Though I doubt I'm handling things correctly
everywhere notmuch-wise, wrt talloc, etc.
