fts-solr: Add and use FTS_SOLR_USER_CONTEXT_REQUIRE Satisfies static analyzers

Updated copyright notices to include the year 2018.

fts-solr: Fixed HTTPS support by properly propagating SSL client settings from mail_user.

fts-solr: Escape {} chars when sending queries Fixes: java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986 Based on patch by Michael Welsh Duggan

global: Change string position/length from unsigned int to size_t Mainly to avoid truncating >4GB strings, which might potentially cause some security holes. Normally there are other limits, which prevent such excessive strings from being created in the first place. I'm sure this didn't find everything. Maybe everything could be found with compiler warnings. -Wconversion kind of does it, but it gives way too many unnecessary warnings. These were mainly found with: grep " = strlen" egrep "unsigned int.*(size|len)"

lib-storage: add no_fts in struct mail_search_arg When flag is set, FTS will not be performed. fts plugin: handle no_fts flag No fts will be performed once flag is set. Original patch from Timo Sirainen <timo.sirainen@dovecot.fi>

fts-solr: Changed default operator to AND to fix multi-word queries. Previously for example searching from:foo@example.com was expanded to foo OR example OR com. Now it's foo AND example AND com, which makes a lot more sense.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

fts-solr: Fixed sending empty parameters. Solr probably doesn't do anything useful with them, but we shouldn't get 400 Bad Request errors.

fts-solr: Fixed escaping query parameters. Solr documentation says that "quoted string" would already work without escaping, but that doesn't seem to be true (we were also missing the \" escaping there). So we'll now escape all the special characters without quotes around it, which seems to work. Also added '/' to list of special characters, which is used by Solr 4.0.

fts-solr: "highest UID for mailbox" lookup was actually returning "highest UID for user" If the default operator was OR instead of AND. This affected indexing mails in newly created mailboxes.

various: use new uni_utf8_get_char*() interface No need for additional uni_utf8_char_bytes() calls if you can parse and know the size with one call. Signed-off-by: Phil Carmody <phil@dovecot.fi>

fts-solr: laxer check of uni_utf8_get_char_n() return value If uni_utf8_get_char*() were changed to return the number of bytes in the character on success, then all we care about is it being > 0 (i.e. not error, not truncated). Signed-off-by: Phil Carmody <phil@dovecot.fi>

fts-solr: Fixed memory leak at user deinit.

fts-solr: Crashfixes

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

fts: Added fts_no_autofuzzy setting to require exact matches for found results. This is done by using the FTS search results as only filters on which the regular non-FTS search is done.

Updated copyright notices to include year 2014.

fts-solr: Fixed support for multiple Solr hosts when same process handles multiple users. E.g. indexer-worker was always using only the first user's Solr host.

fts-solr: Don't crash if fts_solr setting is invalid.

fts-solr: Use built-in lib-http instead of libcurl. Removed libcurl dependency.

Oops :) Update copyrights to 2013 without breaking all .c files.

Updated copyright notices to include year 2013.

fts-solr: Deinit solr connection at plugin unload.

fts-solr: Reverted previous change, it only crashes. The plugin is already unloaded at lib_atexit() time.

fts-solr: Free the solr_connection at exit.

Reversed recent "short utf8" changes. Solr code needs to parse the UTF8 input explicitly anyway to encode the XML characters. And all the character checks were already done in it.

fts-solr: Marked as FTS_BACKEND_FLAG_BUILD_SHORT_UTF8

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]
