- Update to 1.4.14:
  * API:
    + Xapian::QueryParser: Handle "" inside a quoted phrase better.  In a quoted
      boolean term, "" is treated as an escaped ", so handle it in a compatible way
      for quoted phrases.  Previously we'd drop out of the phrase and start a new
      phrase.  Fixes #630, reported by Austin Clements.
    + Xapian::Stem: The constructor which takes a stemmer name now takes an
      optional second bool parameter - if this is true, then an unknown stemmer
      name falls back to using the "none" stemmer instead of throwing an exception.
      This allows simply constructing a stemmer from an ISO language code without
      having to worry about whether there's a stemmer for that language, and
      without having to handle an exception if there isn't.
    + Xapian::Stem: Fix a bug with handling 4-byte UTF-8 sequences which
      potentially affects most of the stemmers.  None of the stemmers work in
      languages where 4-byte UTF-8 sequences are part of the alphabet, but this
      bug could result in invalid UTF-8 sequences in terms generated from text
      containing high Unicode codepoints such as emoji, which can cause issues (for
      example, in some language bindings).  Fix synced from Snowball git post
      2.0.0.
    + Xapian::Stem: Add a new is_none() method which tests if this is a "none"
      stemmer.
    + Xapian::Weight: The total length of all documents is now made available to
      Xapian::Weight subclasses, and this is now used by DLHWeight, DPHWeight and
      LMWeight.  To maintain ABI compatibility, internally this still fetches the
      average length and the number of documents, multiplies them, then rounds the
      result, but in the next release series this will be handled directly.
    + Xapian::Database::locked() on an inmemory database used to always return
      false, but an inmemory Database is always actually a WritableDatabase
      underneath, so now we always report true in this case because it's really
      always report being locked for writing.

Wed Jan 15 09:12:32 UTC 2020 - Antonio Larrosa <alarrosa@suse.com>
- Update to 1.4.14:
* API:
+ Xapian::QueryParser: Handle "" inside a quoted phrase better. In a quoted
boolean term, "" is treated as an escaped ", so handle it in a compatible way
for quoted phrases. Previously we'd drop out of the phrase and start a new
phrase. Fixes #630, reported by Austin Clements.
+ Xapian::Stem: The constructor which takes a stemmer name now takes an
optional second bool parameter - if this is true, then an unknown stemmer
name falls back to using the "none" stemmer instead of throwing an exception.
This allows simply constructing a stemmer from an ISO language code without
having to worry about whether there's a stemmer for that language, and
without having to handle an exception if there isn't.
+ Xapian::Stem: Fix a bug with handling 4-byte UTF-8 sequences which
potentially affects most of the stemmers. None of the stemmers work in
languages where 4-byte UTF-8 sequences are part of the alphabet, but this
bug could result in invalid UTF-8 sequences in terms generated from text
containing high Unicode codepoints such as emoji, which can cause issues (for
example, in some language bindings). Fix synced from Snowball git post
2.0.0.
+ Xapian::Stem: Add a new is_none() method which tests if this is a "none"
stemmer.
+ Xapian::Weight: The total length of all documents is now made available to
Xapian::Weight subclasses, and this is now used by DLHWeight, DPHWeight and
LMWeight. To maintain ABI compatibility, internally this still fetches the
average length and the number of documents, multiplies them, then rounds the
result, but in the next release series this will be handled directly.
+ Xapian::Database::locked() on an inmemory database used to always return
false, but an inmemory Database is always actually a WritableDatabase
underneath, so now we always report true in this case because it's really
always report being locked for writing.
+ testsuite:
* Fix failing multi_glass_remoteprog_glass tests on x86. When the tests are
run under valgrind, remote servers should be run using the runsrv wrapper
script, but this wasn't happening for remote servers in multi-databases - now
it is. Also, previously runsrv only used valgrind for the remote for an x86
build that didn't use SSE, but it seems there are x87 instructions in libc
that are affected by valgrind not providing excess precision, so do this for
x86 builds which use SSE too. Together these changes fix failures of
topercent2, xor2, tradweight1 under backend multi_glass_remoteprog_glass on
x86.
* Fix C++ One-Definition Rule (ODR) violation in testsuite code. Two different
source files linked into apitest were each defining a different `struct
test`. Wrap each in an anonymous namespace to localise it to the file it is
defined and used in. This was probably harmless in practice, unless trying
to build with Link-Time Optimisation or similar (which is how it was
detected).
* Test all language codes in stemlangs1. The testsuite hardcodes a list of
supported language codes which hadn't been updated since 2008.
* Improve DateRangeProcessor test coverage.
+ matcher:
* Handle pruning under a positional check. This used to be impossible, but
since 1.4.13 it can happen as we now hoist AND_NOT to just below where we
hoist the positional checks. The code on master already handles pruning here
so this bug is specific to the RELEASE/1.4 branch.
* When searching with collapsing over multiple shards, at least some of which
are remote, uncollapsed_upper_bound could be too low and
uncollapsed_lower_bound too high. This was causing assertion failures in
testcases msize1 and msize2 under test harness backends
multi_glass_remoteprog_glass and multi_remoteprog_glass.
* Internally we no longer calculate a bogus total_term_count as the sum of
total_length * doc_count for all shards. Instead we just use the sum of
total_length, which gives the total number of term occurrences. This change
should improve the estimated collection_freq values for synonyms.
* Several places where we might divide zero by zero in a database where wdf was
always zero have been fixed.
+ build system:
* configure: Stop using AC_FUNC_MEMCMP. The autoconf manual marks it as
"obsolescent", and it seems clear that nobody's relying on it as we're
missing the "'AC_LIBOBJ' replacement for 'memcmp'" which it would try to
use if needed.
+ documentation:
* HACKING: Replace release docs with pointer to the developer guide where they
are now maintained.
+ portability:
* Eliminate 2 uses of atoi(). These are potentially problematic in a
multithreaded application if setlocale() is called by another thread at the
same time.
* Don't check __GNUC__ in visibility.h as the configure probe before defining
XAPIAN_ENABLE_VISIBILITY checks that the visibility attributes work. This
probably makes no difference in practice, as all compilers we're aware of
which support symbol visibility also define __GNUC__.
* Document Sun C++ requires --disable-shared.
- Update to 1.4.13:
+ API:
* Fix write one past end of std::vector on certain QueryParser parser errors.
This is undefined behaviour, but the write was always into reserved space, so
in practice we'd actually get away with it (it was noticed because it
triggers an error when running under ubsan and using libc++).
* MSet::get_matches_estimated(): Improve rounding of result - a bug meant we
would almost always round down.
* Optimise test for UTF-8 continuation character. Performing a signed char
comparison shaves an instruction or two on most architectures.
* Database::get_revision(): Return revision 0 for a Database with no shards
rather that throwing InvalidOperationError.
* DPHWeight: Avoid dividing by 0 when searching a sharded database when one
shard is empty. The result wasn't used in this case, but it's still
undefined behaviour. Detected by UBSan.
+ testsuite:
* The "singlefile" test harness backend manager now creates databases by
compacting the corresponding underlying backend database (creating it first
if need be) rather than always creating a temporary database to compact.
* Enable compaction testcases for multi and singlefile test harness backends.
* Add generated database support for remoteprog and remotetcp test harness
backends.
* Add test harness support for running testcases using a multi database
comprised of one local and one remote shard, or two remote shards.
* Check if removing existing multi stub failed. Previously if removing an
existing stub failed, the test harness would create a temporary new stub and
then try to rename it over the old one, which will always fail on Microsoft
Windows.
* Wait for xapian-tcpsrv processes to finish before moving on to the next
testcase under __WIN32__ like we already do on POSIX platforms.
+ matcher:
* Optimise OP_AND_NOT better. We now combine its left argument with other
connected and-like subqueries, and gather up and hoist the negated subqueries
and apply them together above the combined and-like subqueries, just below
any positional filters.
* Optimise OP_AND_MAYBE better. We now combine its left argument with other
connected and-like subqueries, and gather up and hoist the optional
subqueries and apply them together above the combined and-like subqueries and
any hoisted positional filters.
* Treat all BoolWeight queries as scaled by 0 - we can optimise better if we
know the query is unweighted.
+ glass backend:
* Allow zlib compression to reduce size by one byte. We were specifying an
output buffer size one byte smaller than the input, but it appears zlib won't
use the final byte in the buffer, so we actually need to pass the input size
as the output buffer size.
* Only try to compress Btree item values > 18 bytes, which saves CPU time
without sacrificing any significant size savings.
+ remote backend:
* Fix match stats when searching with collapsing over multiple shards and at
least some shards are remote.
* Ignore orphaned remote protocol replies which can happen when searching with
a remote shard if an exception is thrown by another shard.
* Wait for xapian-progsrv child to exit when a remote Database or
WritableDatabase object is closed under __WIN32__ like we already do for
POSIX platforms.
+ documentation:
* Correct documentation of initial messages in replication protocol.
+ tools:
* quest: Report bounds and estimate of number of matches.
* xapian-delve: Improve output when database revision information is not
available. We now specially handle the cases of a DB with multiple shards
and a backend which doesn't support get_revision().
+ portability:
* Fix warning from GCC 9 with -Wdeprecated-copy (which is enabled by -Wextra)
if a reference to an Error object is thrown.
* Suppress GCC warning in our API headers when compiling code using Xapian with
GCC and -Wduplicated-branches.
* Mark some internal classes as final (following GCC -Wsuggest-final-types
suggestions to allow some method calls to be devirtualised).
* Fix to build with --enable-maintainer-mode and Perl < 5.10, which doesn't
have the `//=` operator. It's unlikely developers will have such an old
Perl, but the mingw environment on appveyor CI does. The use of `//=` was
introduced by changes in 1.4.10.
- Update to 1.4.12:
+ API:
* Xapian::PostingSource: When a PostingSource without a clone() method is used
with a Database containing multiple shards, the documented behaviour has
always been that Xapian::InvalidOperationError is thrown. However, since at
least 1.4.0, this exception hasn't been thrown, but instead a single
PostingSource object would get used for all the shards, typically leading to
incorrect results. The actual behaviour now matches what was documented.
* Xapian::Database: Add size() method which reports the number of shards.
* Xapian::Database::check(): You can now pass a stub database which will check
all the databases listed in it (or throw Xapian::UnimplementError for
backends which don't support checking).
* Xapian::Document: When updating a document use a emplace_hint() to make the
bulk insertion O(n) instead of O(n·log(n)), and use std::move() to avoid
copying OmDocumentTerm objects.
* Xapian::Query: Add missing get_unique_terms_end() method.
* Xapian::iterator_valid(): Implement for Utf8Iterator
+ testsuite:
* Fix keepalive1 failures on some platforms. On some platforms a timeout
gives NetworkTimeoutError and on others NetworkError - since 1.4.10 changed
to checking the exact exception type, keepalive1 has been failing on the
former set of platforms. We now just check for NetworkError or a subclass
here (since NetworkTimeoutError is a subclass of NetworkError).
* Run cursordelbug1 testcase with multi databases too.
+ matcher:
* Ownership of PostingSource objects during the match now makes use of the
optional reference-counting mechanism rather than a separate flag.
+ remote backend:
* Fix remote protocol design bug. Previously some messages didn't send a reply
but could result in an exception being sent over the link. That exception
would then get read as a response to the next message instead of its actual
response so we'd be out of step.
This fix necessitated a minor version bump in the remote protocol (to 39.1).
If you are upgrading a live system which uses the remote backend, upgrade the
servers before the clients.
* Fix socket leaks on errors during opening a database.
* Don't close remote DB socket on receiving EOF as the levels above won't
know it's been closed and may try to perform operations on it, which would be
problematic if that fd gets reused in the meantime. Leaving it open means
any further operations will also get EOF.
* We add a wrapper around the libc socket() function which deals with the
corner case where SOCK_CLOEXEC is defined but socket() fails if it is
specified (which can happen with a newer libc and older kernel).
Unfortunately, this wrapper wasn't checking the returned value from socket()
correctly, so when SOCK_CLOEXEC was specified and non-zero it would create
the socket() with SOCK_CLOEXEC, then leak that one and create it again
without SOCK_CLOEXEC. We now check the return value properly.
* Fix potential infinite loop in ValueCountMatchSpy::merge_results() if passed
serialised results with extra data appended (which shouldn't happen in normal
use).
+ build system:
* Current versions of valgrind result in false positives on current versions of
macOS, so on this platform configure now only enables use of valgrind if it's
specified explicitly.
* Refactor macros to probe for compiler flags so they automatically cache
their results and consistently report success/failure.
* Rename our custom TYPE_SOCKLEN_T macro to XAPIAN_TYPE_SOCKLEN_T. The
AX_TYPE_SOCKLEN_T macro defines an alias of TYPE_SOCKLEN_T for itself which
means it can get used instead in some situations, but it isn't compatible
with our macro. We can't just switch to AX_TYPE_SOCKLEN_T as it doesn't
handle cases we need, so just rename our macro to avoid potential problems.
+ documentation:
* Improve API documentation for Xapian::Query class. Add missing doc
comments and improve some of the existing ones.
* Add Unicode consortium names and codes for categories from Chapter 4, Version
11 of the Unicode standard. Patch from David Bremner.
* Improve configure --help output - drop "[default=no]" for --enable-*
options which default off.
Палаузов.
* Fix API documentation typo - Query::op (the type) not op_ (a parameter name).
* Note which version Document::remove_postings() was added in.
* In the remote protocol documentation, MSG_REPLACEDOCUMENTTERM was documented
as not having a reply, but actually REPLY_ADDDOCUMENT is sent.
* Update list of <xapian/iterator.h> users.
+ tools:
* copydatabase: A change in 1.4.6 which added support for \ as directory
separator on platforms where that's the norm broke the code in copydatabase
which removes a trailing slash from input databases.
+ portability:
* Add missing '#include <cstring>'.
* Fix str() helper function when converting the most negative value
of a signed integer type.
* Avoid calling close() on fd we know must actually be a WIN32 SOCKET.
* Include <ios> not <iomanip> for std::boolalpha.
* Rework setenv() compatibility handling. Now that Solaris 9 is dead we can
assume setenv() is provided by Unix-like platforms (POSIX requires it). For
other platforms, provide a compatibility implementation of setenv() which
so the compatibility code is encapsulated in one place rather than replicated
at every use.
* Fix maintainer-mode builds on Solaris where /bin/tr is not POSIX compliant.
We now use the simple workaround suggested by the autoconf manual.
* Improve support for Sun C++:
+ Suppress unhelpful warning for lambda with multiple return statements.
+ Enable reporting the tags corresponding to warnings, which we need
to know in order to suppress any new unhelpful warnings.
+ Adjust our workaround for bug with this compiler's <cmath> header to avoid
a compiler warning.
+ Use -xldscope=symbolic for Sun C++. This flag is roughly equivalent to
-Bsymbolic-functions which we've probed for with GNU ld since Xapian 1.0.0.
- Update to 1.4.11:
+ API:
* MSet::SNIPPET_CJK_NGRAM - new flag for use with MSet::snippet() to enable
support for selecting and highlighting snippets which works with the
QueryParser and TermGenerator FLAG_CJK_NGRAM flags. This mode can also be
enabled by setting environment variable XAPIAN_CJK_NGRAM to a non-empty
value. (There was nominally already support for XAPIAN_CJK_NGRAM in
MSet::snippet(), but it didn't work usefully - the highlighting added was all
empty start/end pairs at the end of the span of CJK characters containing the
CJK ngram terms, which to the user would typically look like it was selecting
the end of the text and not highlighting anything).
* Deprecate XAPIAN_CJK_NGRAM environment variable. There are now flags which
can be used instead in all cases, and there's sadly no portable thread-safe
way to read an environment variable so checking environment variables is
problematic in library code that may be used in multithreaded programs.
* Query::OP_ELITE_SET currently incorrectly recursively flattens any OP_OR (or
OP_OR-like) subqueries into the list of subqueries it selects from - until
that's fixed, we now select from the full exploded list rather than the last
n (where n is the number of direct subqueries of the OP_ELITE_SET).
+ testsuite:
* Testcases which need a generated database now get run with a sharded
database.
* Avoid using strerror() in the testsuite which removes an obstacle to running
tests in parallel in separate threads.
+ matcher:
* Extend detection of cases of OP_SYNONYM with disjoint subqueries (which means
we don't need document length) which was added in 1.4.8 - we now detect when
all subqueries are different terms, or when all subqueries are
non-overlapping wildcards. The second case is what QueryParser produces for
a wildcard or partial query with a query prefix which maps to more than one
term prefix.
+ glass backend:
* Handle an empty value slot lower bound gracefully. This shouldn't happen for
a non-empty slot, but has been reported by a notmuch user so it seems there
is (or perhaps was as the database was several years old) a way it can come
about. We now check for this situation and set the smallest possible valid
lower bound instead, so other code assuming a valid lower bound will work
correctly.
+ chert backend:
* Handle an empty value slot lower bound gracefully, equivalent to the change
made for glass.
+ documentation:
* HACKING: We no longer use auto_ptr<>.
* NEWS: Correct factual error in old entry - the 0.4.1 release was Open Muscat
not OmSee (the OmSee name was only applied after that final release was made,
and only used internally to BrightStation).
+ portability:
* Suppress more clang -Wself-assign-overloaded warnings in testcases which are
deliberately testing handling of self-assignment.
* Add missing includes of <cerrno>.
+ debug code:
* When configured with --enable-log, the O_SYNC flag was always specified when
opening the logfile, with the intention that the most recent log entries
wouldn't get lost if there was a crash, but O_SYNC can incur a significant
performance overhead and most debugging is not of such crashes. So we no
longer specify O_SYNC by default, but you can now request synchronous logging
by including %! anywhere in the filename specified with XAPIAN_DEBUG_LOG
(the %! is replaced with the empty string). We also now use O_DSYNC if
available in preference to O_SYNC, since the mtime of the log file isn't
important.
- Update to 1.4.10:
+ API:
* DatabaseClosedError: New exception class thrown instead of DatabaseError when
an operation is attempted which can't be completed because it involves a
database which close() was previously called on. DatabaseClosedError is a
subclass of DatabaseError so existing code catching DatabaseError will still
work as before.
* DatabaseNotFoundError: New exception class thrown instead of
DatabaseOpeningError when the problem is the problem is "file not found" or
similar. DatabaseNotFoundError is a subclass of DatabaseOpeningError so
existing code catching DatabaseOpeningError will still work as before.
* Query: Make &=, |= and ^= on Query objects opportunistically append to
an existing query with a matching query operator which has a reference
count of 1. This provides an easy way to incrementally build flatter query
trees.
* Query: Support `query &= ~query2` better - this now is handled exactly
equivalent to `query = query & ~query2` and gives `query AND_NOT query2`
instead of `query AND (<alldocuments> AND_NOT query2)`.
* QueryParser: Now uses &=, |= and ^= to produce flatter query trees. This
fixes problems with running out of stack space when handling Query object
trees built by abusing QueryParser to parse very large machine-generated
queries.
* Stopper: Fix incorrect accents in Hungarian stopword list. Patch from David
Corbett.
+ testsuite:
* Test MSet::snippet() with small and zero lengths.
* Fix testcase stubdb4 annotations - this testcase doesn't need a backend.
* Add PATH annotation for testcases needing get_database_path() to avoid having
to repeatedly list the backends where this is supported in testcase
annotations.
* TEST_EXCEPTION helper macro now checks that the exact specified exception
type is thrown. Previously it would allow a subclass of the specified
exception type, but in testcases we really want to be able to test for an
exact type.
+ matcher:
* Map OP_VALUE_GE/OP_VALUE_LE on an empty slot to EmptyPostList. We already do
this for OP_VALUE_RANGE, and it's a little more efficient than creating a
postlist object which checks the empty value slot.
+ glass backend:
* We no longer flush all pending positional changes when a postlist, termlist
or all-terms is opened on a modified WritableDatabase. Doing so was
incurring a significant performance cost, and the first of these happens
internally when `replace_document(term, doc)` is used, which is the usual way
to support non-numeric unique ids. We now only flush pending positional
changes when committing.
+ remote backend:
* Use poll() where available instead of select(). poll() is specified by
POSIX.1-2001 so should be widely available by now, and it allows watching any
fd (select() is limited to watching fds < FD_SETSIZE). For any platforms
which still lack poll() we now workaround this select() limitation when a
high numbered fd needs to be watched (for example, by trying a non-blocking
read or write and on EAGAIN sleeping for a bit before retrying).
* Stop watching fds for "exceptional conditions" - none of these are relevant
to our usage.
* Remove 0.1s timeout in ready_to_read(). The comment says this is to avoid a
busy loop, but that's out of date - the matcher first checks which remotes
are ready to read and then does a second pass to handle those which weren't
with a blocking read.
+ build system:
* Stop probing for header sys/errno.h which is no longer used - it was only
needed for Compaq C++, support for which was dropped in 1.4.8.
+ documentation:
* docs/valueranges.html: Update to document RangeProcessor instead of
ValueRangeProcessor - the latter is deprecated and will be gone in the next
release series.
* Document RangeProcessor::operator()() returns OP_INVALID to signal it doesn't
recognise a range.
* Update some URLs for pages which have moved.
* Use https for URLs where available.
* HACKING: Update "empty()" section for changes in C++11.
+ portability:
* Suppress clang warnings for self-assignment tests. Some testcases trigger
this new-ish clang warning while testing that self-assignment works, which
seems a useful thing to be testing - at least one of these is a regression
test.
* Add std::move to fix clang -Wreturn-std-move warning (which is enabled by
-Wall).
* Add casts to fix ubsan warnings. These cases aren't undefined behaviour, but
are reported by ubsan extra checks implicit-integer-truncation and/or
implicit-conversion which it is useful to be able to enable to catch
potential bugs.
* Fix check for when to use _byteswap_ulong() - in practice this would only
have caused a problem if a platform provided _byteswap_ushort() but not
_byteswap_ulong(), but we're not aware of any which do.
* Fix return values of do_bswap() helpers to match parameter types (previously
we always returned int and only supported swapping types up to 32 bits, so
this probably doesn't result in any behavioural changes).
* Only include <intrin.h> if we'll use it instead of always including it when
it exists. Including <intrin.h> can result in warnings about duplicate
declarations of builtin functions under mingw.
* Remove call to close()/closesocket() when the argument is always -1 (since
the change to use getaddrinfo() in 1.3.3).
