documentation:
* Improve omindex --help docs for --duplicates.
* Document that $log will start to return an error message in 1.5.0, and that
one can wrap it using a $if with no action now to be future-proof.
indexers:
* Add built-in support for iso-8859-15 so we can handle it without iconv.
This charset is a variant of iso-8859-1 with 8 characters changed, most
notably including the euro currency symbol. It's the most commonly seen
charset we didn't have built-in support for.
* Optimise converting us-ascii to UTF-8 to do nothing, like we already do when
converting UTF-8 to UTF-8.
* scriptindex:
+ Add new 'gap' action which provides a way to leave a gap in the term
positions between fields to prevent phrases and positional operators from
matching across fields.
omega:
* Fix error handling in $lookup. We now check for errors from cdb_init()
and cdb_get(). We've never checked for errors from cdb_init(), while
for cdb_get() this bug was introduced by a warning fix in 1.2.20.
templates:
* Future-proof use of $log against changes in 1.5.0.
documentation:
* Improve docs for OmegaScript $hitlist{}.
* Fix RST formatting errors in omega docs.
* Clarify use of Q prefix for unique ID terms - it was described as "reserved",
but the use of "Q" is really just a convention (and in fact omindex uses "U"
not "Q").
* Clarify scriptindex's weight action takes parameter >= 0.
* Correct typo in OmegaScript $add parameter documentation.
indexers:
* omindex:
+ Fix typo in mimetypes used for Apple iWork documents ("apply" instead of
"apple") which meant that these documents weren't actually being indexed.
Patch from Bruno Baruffaldi.
+ Pipe input to ps2pdf as this accepts input on stdin. Possibility pointed
out by Gaurav Arora.
* scriptindex:
+ If parsedate action's format includes %z adjust for the timezone if
possible (this requires the non-POSIX tm_gmtoff member of struct tm)
and flag an error for other platforms.
+ If parsedate action's format include %Z flag an error as that doesn't
seem to be usefully supported by strptime() anywhere.
+ Fix parsedate action to treat formats without a timezone as being UTC
instead of localtime.
+ Add date=unixutc. The existing date=unix works in localtime which is
unhelpful if you want to use it on the output of parsedate since that's in
UTC; date=unixutc is just like date=unix except it always works in UTC.
+ The date action now emits a warning for invalid values. The documentation
used to say "invalid values are ignored at present", but it's more helpful
to flag bad data than quietly ignore it.
+ We now check the date action's parameter at script parse time and unknown
values result in an error and nothing being indexed. Previously an unknown
format uselessly resulted in the terms D, M and Y literally being added to
every document.
+ The split action now supports a new "prefixes" split style. This gives all
the prefixes from the split, so split=/,prefixes on a file path gives all
parent directories.
omega:
* Remove documented limitation of $subdb and $subid - the implementation
assumed that each omega database name corresponded to a single Xapian
database, and if a database name referred to a stub database file expanding
to multiple Xapian databases then they would misbehave. Such cases are now
handled properly as well.
* Extend $addfilter to support adding negated filters via a new optional second
argument which specifies the type of filter to add.
* Stop $sort from needlessly ensuring the match has run.
* Handle corner case of nested $hitlist gracefully instead of potentially
entering an infinite loop.
testsuite:
* omegatest: Avoid setting TZ globally during tests as that hides bugs where
behaviour depends on the local timezone when it shouldn't.
* omegatest: Support testing when built using LeakSanitizer by suppressing
leak reports for cached compiled pcre regular expressions. These aren't
released when the program exits but aren't memory leaks.
build system:
* Remove outdated deprecation warning suppression which was there to support
building from git in the run up to 1.3.2 - a development version which is
nearly 5 years ago now.
portability:
* Fix problems with fallback strptime() implementation which was being included
in the wrong binary, and was lacking a required const_cast on the return
value.
* 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() so the
compatibility code is encapsulated in one place rather than replicated at
every use.
indexers:
* omindex:
+ outlookmsg2html: Handle Subject, Date, and From headers.
omega:
* In $div and $mod we were converting a non-zero denominator from string to int
twice for no good reason.
testsuite:
* omegatest: Fix testcase which was failing if the local timezone was behind
UTC. This testcase was added in 1.4.10.
* omegatest: Tweak to not fail when $time not supported - it seems that the
OS time functions we use report an error on GNU Hurd for unknown reasons.
build system:
* Sync up probes for OS time functions in omega's configure with those in
xapian-core which may solve $time not being supported on GNU Hurd.
portability:
* Add missing includes of <cerrno>. Fixes#776, reported by Matthieu Gautier.
* Stop using htonl()/ntohl() in a non-network context which should improve
portability to platforms without a POSIX-like socket API.
documentation:
* Use https for URLs where supported.
indexers:
* omindex:
+ Index .apxl and .kth files as Apple Keynote. The .apxl extension is used
for the XML files inside .key bundles/directories which hold the text
content of the presentation, and by handling them we can index .key
directories more usefully. It seems they are also sometimes found by
themselves. Keynote themes have a .kth extension, and key2text can also
handle these.
+ Pipe input to pdftotext, pdfinto and dpkg. These tools all support piping
an input file on stdin, which can be a little more efficient when we
already have the file open (e.g. to determine its type using libmagic, or
to calculate its checksum).
+ An empty string for the start directory is now flagged as an error.
Previously `/` was used instead, which is unlikely to be what is wanted
(and `/` can be explicitly specified if that really is what is wanted).
+ Fix emulation of stderr redirection when the indexer's stderr has been
closed. We try to avoid using the shell when running external filters, and
emulate 2>/dev/null in commands, but if the indexer's stderr was closed
this emulation was buggy and would make give the filter a closed stderr
instead of one redirected to /dev/null.
+ When emulating redirection to /dev/null, we now open /dev/null once and
dup that fd each time which is a little more efficient and simplifies the
code.
* scriptindex:
+ date=unix is now a no-op for empty input - previously it would unhelpfully
add boolean date terms for 1970-01-01.
+ Warn for empty filename in LOAD action. Previously this gave a slightly
confusing error: "Couldn't load file '': No such file or directory"
+ Unknown command-line options now cause scriptindex to give a non-zero exit
status.
testsuite:
* omegatest: Add testcase for SPAN.n on different slots.
* omegatest: Update expected QueryParser output for the xapian-core change to
produce flatter Query trees.
build system:
* Use AM_ICONV to detect iconv() which should handle non-system install of GNU
libiconv properly. Fixes#775, reported by Ryan Schmidt.
portability:
* Provide fall-back strptime() implementation for platforms which don't provide
it, using the C++11 std::get_time() function. We use strptime() directly
where it's available as some older C++11 compilers seem to lack
std::get_time() (GCC 4.8 for example). This is used by the parsedate action,
which was added in 1.4.6.
indexers:
* omindex:
+ Try harder to avoid opening a file being indexed more than once by
reusing the file descriptor in more cases.
+ Hint to the OS not to cache output from external filters which require
using a temporary file.
* scriptindex:
+ If the LOAD action successfully opens a file but hits a read error the
error message now reports the file name correctly. Previously it would
report the partial file contents read so far instead of the file name.
portability:
* We no longer call posix_fadvise() with POSIX_FADV_NOREUSE under Linux,
since it's still not implemented there. We also now only call
posix_fadvise() with POSIX_FADV_DONTNEED right before we close the file
descriptor under Linux.
indexers:
* omindex:
+ Improve date handling in .eml files. We now handle a "Date:" header
without the day of the week, which is allowed by RFC822 and RFC2822
(though seems rare in practice). If the date can't be parsed, we now
just omit the date information rather than failing to process the file.
+ Add support for indexing Apple iWork documents (Keynote (.key), Numbers
(.numbers) and Pages (.pages)) using libetonyek. Currently only the file
variants are handled since omindex doesn't currently support indexing a
directory as a document.
+ Index Visio files using vsd2xhtml.
+ Extend --filter to support filters which produce SVG as output.
+ Handle SVG embedded in XML with svg: namespace prefix.
+ Add --read-filters option to read a list of filters from a file, each line
of which is a rule as passed to --filter. Based on a patch from Gaurav
Arora.
+ Add new --mime-type-match option which allows specifying a MIME
Content-Type for a given shell filename pattern pattern (with the special
Content-Type values "ignore" and "skip" supported, as for --mime-type).
+ Adjust --mime-type to allow ':' in the extension. A valid MIME
Content-Type can't contain a colon, so if the argument to --mime-type
contains more than one colon it makes more sense to split at the *last*
colon (we used to split at the first), as an extension could conceivably
contain a colon. Mostly this change is for consistency with the new
--mime-type-match option, where the leafname pattern could reasonably
contain a colon.
+ Remove failed entries for ignored files. If a file is mapped to
pseudo-mimetype "ignore" then remove any existing failure record for it so
that ignored files so we don't potentially end up with a lot of cruft
failure records for files we are no longer trying to index.
+ If a file fails to index due to failing to allocate enough memory we now
try to flag it as failed to index so it will be skipped by default on
future runs. This should help to avoid indexing getting stuck on
problematic files.
+ Add a "pages" field with the number of pages in the document where we
know how to determine this (currently only for PDF files for which pdfinfo
reports this information).
+ Handle initially empty database exactly the same was as when --overwrite
is specified. This probably has no user-visible consequences, but it's
cleaner for the handling to be exactly the same.
* scriptindex:
+ Improve scriptindex diagnostic messages. All diagnostics are now labelled
as "error", "warning" or "note" as appropriate, and we now consistently
report "FILE:LINE:" (and also "COLUMN:" in most cases) to make it clearer
where the problem lies.
+ Add new "split" action which splits the text on a specified delimiter and
executes the following actions for each piece. Based on a patch by Gaurav
Arora.
+ Missing whitespace after the closing " on an action argument is now
flagged as an error. Previously scriptindex would attempt to parse
the following characters as the next action.
+ Support C-like escapes for quoted parameter values. Notably this means it
is now possible to include `"` in quoted parameter values.
omega:
+ Value-based date range filters can now be specified via CGI parameters
START.N, END.N and/or SPAN.N where N is a value slot number, allowing
multiple concurrent filters on different slots to be specified.
+ Support YYYY and YYYYMM limits in term-based date ranges. Previously
value-based date ranges supported these as limits, but term-based date
ranges gave an error.
+ Add stem_strategy option and deprecate existing stem_all option in favour
of this new more versatile option.
+ Support "natural" $sort option via new flag "#" which sorts embedded
natural numbers in numerical order.
+ Support numeric $sort option via new flag "n", similar to GNU sort -n.
+ Rewrite field parsing to be more efficient, and store fields in an
unordered_map for faster lookup.
omega:
* New OmegaScript $unique command. The existing $uniq only removes adjacent
entries (like the Unix uniq command) so to fully remove duplicates you need a
sorted input. Sometimes it is desirable to remove duplicates from an
unsorted list without changing the order of the entries which are left, so
add $unique to do that. If the list is sorted already, then $uniq is more
efficient.
* Fix $map to cleanly reject a single argument.
templates:
* templates/query: Merge multiple entries in the term frequency information,
which came from searching several prefixes by default. Reported by Alistair
Buxton on #xapian-discuss.
* When multiple words with the same stem are in the query string we now fully
eliminate duplicates when showing term frequency information.
general:
* Fix generate_sample() (used by OmegaScript $truncate and omindex) to return
an empty sample instead of throwing an exception when the requested sample
size is less than the size of the truncation indicator string. Patch from
Addy. Fixes https://trac.xapian.org/ticket/754 reported by Gaurav Arora.
indexers:
* Check for the HTML5 doctype or legacy doctype declaration and use default
charset UTF-8 if either is present. Previously we always used ISO-8859-1,
which is correct for older HTML versions, but not for HTML5.
* omindex:
+ When running commands without going through the shell, emulate shell exit
codes 127 (for command not found) and 126 (for other cases where we fail to
run the command). This means the "missing filter" handling should now work
properly for such commands. Noted by Gaurav Arora.
+ Index POD files despite minor formatting errors. We now pass
--errors=stderr to pod2text so that minor formatting errors don't prevent
us from indexing a file. (It may seem that --errors=none is a better
option, but for podlators < 4.11 that results in an ERRATA section in the
generated text version which we then end up indexing; 4.11 fixed that but
we can't assume that's in use). Reported by Gaurav Arora.
* omindex:
+ Check file size before calling libmagic to get the mime type, since
reading the file size is a much cheaper check and we can skip the
libmagic test if the file is empty or larger than the specified
maximum size. Patch from caiyulun.
* scriptindex:
+ Avoid some unnecessary copying of Action objects by making use of C++11
features.
+ Consistently send errors to stderr - some were sent to stdout.
Patch from Gaurav Arora.
+ Add new "hextobin" action. Based on a patch from Gaurav Arora.
+ Warn about non-integer arg to hash.
+ Fix hash action without an argument, which was failing with an assertion.
Based on a patch by Gaurav Arora: https://github.com/xapian/xapian/pull/189
+ Reject 'hash' with argument < 6. The hashing truncates and then adds a
6 character hash of the removed part, so can't produce a result shorter
than 6 characters. Patch from Gaurav Arora.
+ Look for alphanumerics when parsing index actions. None of the current
index actions contain digits, but we give more helpful error messages this
way.
+ Deprecate allowing spaces around = in scripts. This was never documented
as supported, and leads to a missing argument quietly swallowing the next
action rather than using an empty value or giving an error. Reported by
Gaurav Arora in https://github.com/xapian/xapian/pull/182
+ In boolean and unique actions, add a colon between prefix and term when
the term starts with a colon. This means the mapping is reversible, and
matches what omega actually does in this case when it tries to reverse the
mapping. Thanks to Andy Chilton for pointing out this corner case.
+ Add parsedate and valuepacked actions. Together these assist adding date
values for sorting and date range filtering. Based on a patch from Gaurav
Arora.
+ Use DB_RETRY_LOCK to wait if the database is already in use rather than
sleeping for a second and retrying. On most platforms this means we make a
blocking request for the lock, and even on platforms where that's not
supported, we now sleep and retry inside libxapian, and without having to
throw and catch an exception each time.
* scriptindex:
+ Reject index scripts with multiple "unique" actions. We don't handle this
case sensibly, and it doesn't seem like it really has a use, so better to
give an error for people who do this inadvertently.
omega:
* $freq: Speed up some cases by avoiding throwing and catching an exception
when we know the MSet has no term frequency information.
* $sort: New OmegaScript command which does a string sort on an OmegaScript
list, with u (unique) and r (reverse) options.
* $cond: New OmegaScript conditional multi-way conditional. Inspired by LISP's
COND, this provides a neater way to write a cascade of $if checks.
* $switch: New OmegaScript multi-way conditional which provides an even neater
way to write a cascade of $if{$eq{X,VALUE1},$if{$eq{X,VALUE2},...}}.
* $subdb and $subid: New commands which report the subdatabase name and the
docid in that subdatabase.
+ $termprefix and $unprefix: New OmegaScript commands which expose the existing
code inside omega for splitting up a term.
* Use str() to convert time_t to string, which is simpler code and faster than
using snprintf().
* New $seterror command to set the error message. Implemented by Gaurav Arora.
* Make $highlight more efficient. Patch from Vivek Pal.
templates:
* query: Use $prettyurl for the URL shown at the end of each match (previously
we only used it on the URL shown as a fallback when the document has no
title). Split off from changes by Vivek Pal in
https://github.com/xapian/xapian/pull/161
indexers:
* omindex:
+ 1.4.3 added a new --sample option, but contrary to the documentation
the default behaviour was to take the sample from the meta description
(which was the hard-wired behaviour in 1.4.2 and earlier). The default
has now been changed to take the sample from the body.
+ Index .shtm, .xhtml and .xhtm as HTML by default - .shtm is another
extension used for server-parsed HTML (in addition to the more common
.shtml), and .xhtm and .xhtml are XHTML.
+ Fix fallback lookup for extension containing upper case. User mappings
worked, but built-in extension to MIME type mappings were effectively being
ignored (because the result of the function call was not being checked).
Bug introduced in 1.3.4.
+ Fix term-based date ranges, broken by changes in 1.4.2. Found and
diagnosed by Gaurav Arora.
+ Handle date range with start after end better - with term-based ranges,
this used to generate a bogus filter, but now just generates Dlatest.
+ Use Y-term when range starts/ends at year start/end. Previously we used 12
M-terms for these cases.
+ Use full leap-year check when constructing term-based date ranges -
previous code was good until 2100, but even then it would only result
in an extra term being included for a non-existent February 29th in
rare cases.
+ Add support for indexing vCard files if Perl and its Text::vCard module
are available.
+ Recognise application/x-rpm as alternative type since libmagic reports this
rather than application/x-redhat-package-manager.
+ Use official MIME type application/vnd.debian.binary-package for debian
packages. We used to map .deb and .udeb to application/x-debian-package,
but in 2014 (after we added that support for .deb) an official type was
registered with IANA. We now map extensions .deb and .udeb to the official
type, but the unofficial type is still recognised (older versions of
libmagic probably report it, and users may be mapping to it).
+ Handle PHP as MIME type text/x-php. The main difference this makes is that
PHP files which don't have extension '.php' (e.g. .phtml, .phps, .php5,
.ph4, etc) get identified by libmagic as text/x-php and will now be indexed.
It also means that the user can now more easily configure different filters
for HTML and PHP.
+ Don't use meta description as sample by default. Now we have dynamic
snippets (via $snippet), the body text is a better default. Also generated
HTML sometimes has unhelpful content in the meta description. To get the
previous behaviour, use the new omindex command line option:
--sample=description
omega:
* New OmegaScript command $cgiparams which returns a list of the parameter
names.
* Handle tab in a CGI parameter name in the same way as space. Mostly this is
a way to avoid having tabs in CGI parameter names - they aren't useful, but
if they could have tabs in we can't put CGI parameter names in a list.
templates:
* query: Fix highlighting of matching terms. We were using both $snippet and
$highlight, which results in double highlighting and HTML escaping, most
noticeable by literal <strong> and </strong> appearing around matching terms
in the rendered HTML snippet. Reported by Mark Thomas on xapian-discuss.
build system:
* If gen-mimemap failed after creating mimemap.h, the rule wouldn't get rerun.
documentation:
* Replace auto-generated list of the supported MIME types with an
auto-generated table showing the extensions that are mapped to each MIME type
by default. Partly addresses #569, reported by catkin.
indexers:
* omindex: Add support for indexing markdown files (extension .md or .markdown,
mime-type text/markdown, using "markdown" to convert to HTML).
testsuite:
* Add support for "make installcheck" to run tests against installed version.
build system:
* configure: Fail with clear error with xapian-core < 1.4.0.
portability:
* Fix GCC -Wimplicit-fallthrough warning.
* Add missing <ctime> for time_t.
* Avoid snprintf_for formatting fixed-width integers - it results in warnings
about possible output truncation with GCC7 (which aren't actually possible
due to limited input range) and it's a bit heavyweight for this job anyway.
omindex:
+ Also index leafname with _ and & replaced by spaces. Literal spaces are
often avoided in filenames, and "hello_world.txt" ought to be searchable for
via "hello" and "world". Partly addresses #618, reported by Julien
Pfefferkorn.
+ Make named entity look-up (e.g. é -> 233) use the same keyword-lookup
table approach we already use for HTML tags and built-in MIME content-types,
rather than a std::map, which makes it faster while using less memory.
+ Avoid using the shell to run most external commands as it's unnecessary
overhead. For the built-in filters, the only cases which now use a shell
are where we run two unzip commands. For user-specified commands, a simple
and slightly conservative test is used, which should avoid a shell in most
common cases where it isn't needed. Notably, environment variables set
before the command are handled.
+ Track files which couldn't be indexed in the user metadata and skip them by
default on subsequent runs to avoid the costs of repeatedly running a
filter on a file it can't handle. Run omindex with --retry-failed to retry
such files.
+ Overhaul the "per-site" terms:
- 'H' prefix is hostname as before, except that if the term would be > 240
bytes (unlikely but possible) the end is hashed is the same way 'U'
prefix terms are.
- 'P' terms are now added for every directory level, not just the start
URL's path.
- A new 'J' prefix term is added with the start URL (less any trailing
'/'), which means all files indexed from a particular "site" are now
indexed by one term. See #376.
+ Add 'skip' pseudo-mimetype which extensions can be mapped to, and they will
then be reported and skipped (to complement the existing 'ignore'
pseudo-mimetype which causes files with the specified extension to be
quietly ignored).
+ Treat a command of 'true' specially as meaning make the text extraction a
no-op (as actually running /bin/true effectively would). This provides a
way to index some file types by only meta-data. Fixes#519, reported by
Brian Burton.
+ Add support for wildcard mimetypes */* and *. Combined with filter command
``true`` for indexing by meta-data only, you can specify a fall back case
of indexing by meta-data only using ``--filter '*:true'``. From a
suggestion by Brian Burton on xapian-discuss.
+ Index message/rfc822 and message/news. These are individually saved email
messages and news articles.
+ Index archived web page formats MAFF and MHTML.
+ Handle .xla, yet another XL extension.
+ Handle metadata in LibreOffice HTML export (dcterms.subject,
dcterms.description, dcterms.creator and dcterms.contributor).
+ Use zlib's gzopen() instead of invoking "gzip -dc" for compressed Abiword
documents.
+ Add support for %f in command passed to --filter to allow specifying
commands where the input file is not the final argument. Fixed#570,
reported by Charles Atkinson.
+ Allow --filter to handle commands which produce output in a temporary file
rather than on stdout.
+ Allow --filter to specify the character set of the output the filter
produces.
+ Handle application/vnd.ms-excel, text/x-perl and application/x-dvi via
default --filter settings instead of hardcoded cases (now possible thanks
to the new abilities that --filter has).
+ Add support for specifying a MIME subtype of '*' in --filter arguments.
+ Add -track-ctime option to allow omindex to pick up changes to file
ownership and permissions.
+ Index terms from the leafname with an 'F' prefix, rather than treating them
as more body text. (Fixes#633, reported by Emmanuel Garette)
+ The starting URL wasn't previously URL encoded. In 1.2.18, a minimally
intrusive fix was implemented. In 1.3.2, we now encode the starting URL
as we do for the rest of the filename.
+ Don't assume .doc is application/msword but let libmagic decide, since .doc
files may actually be RTF, and sometimes people use .doc for plain-text
documentation.
+ Add support for indexing 'topic' and 'created date' meta-data for
OpenDocument format and HTML.
+ Index "topic" for PDF documents.
+ Commit changes and exit, rather than skipping the current file on most
unexpected errors reading directories or initialising libmagic - otherwise
we can end up deleting a lot of database entries on errors like EHOSTDOWN
when indexing network mounts.
+ Add --opendir-sleep=SECS option to allow working around problems with
indexing files on Microsoft DFS shares.
+ If we get ENOTDIR trying to index a file, skip it quietly (unless in
verbose mode) as we already do if we get ENOENT, since ENOTDIR is what we
get if the file and the directory it was in got removed between us getting
the filename and trying to open it.
+ Handle ENOENT, ENOTDIR and EACCES from readdir().
+ If we've already opened the file (as we often will have if using a modern
libmagic with magic_descriptor() available), then use fstat() on that fd
rather than stat()/lstat() on the pathname.
+ Pass error message string and errno value in ReadError exceptions.
+ Report strerror(errno) if we can't read a file.
+ Filtering via text/html now handles HTML documents which specify a charset.
+ Add support for indexing Microsoft Publisher files using pub2xhtml.
+ Restrict the length of what we consider to be an extension, currently to 7
characters or whatever the longest extension in the mime_map is if it is
longer.
+ Avoid '//' in temporary filenames (cosmetic only).
+ Extend --filter to handle commands which produce HTML on stdout.
+ Don't report an error if a file is deleted (or renamed) between us reading
the directory entry for it and trying to read the file itself by default.
In --verbose mode, the situation is still reported, but now with a
specific message.
+ If omindex receives any of the signals SIGHUP, SIGINT, SIGQUIT or SIGTERM,
then kill any active external filter child process, then handle the signal
as we did before. If setpgid() is available, put each external filter in
its own process group and kill the whole process group when we get a
signal.
+ Use magic_descriptor() if the version of libmagic we're building against
is new enough to have it. This eliminates an extra opening of a file
being indexed in certain cases.
+ Use rst2html to handle .rst and .rest files.
+ Index title with an 'S' prefix rather than no prefix.
+ If the document with the highest existing docid before the run was updated,
we were reporting it as "added", but now we correctly report it as
"updated".
+ Catch and report std::exception explicitly, so failing to allocate memory
is no longer reported as "Unknown exception".
omindex-list: New tool to list URLs of all the documents in a database
(or list of databases) indexed by omindex.
* The HTML parser now explicitly handles <APPLET>, <OBJECT> and <TR>.
* Use a generated compact and efficient table to convert HTML tag names
to enum codes - this is both faster and smaller than the approach we were
using, with the benefit that the table is auto-generated.
* Always use our built-in conversion code for the character sets it can handle
(previously we'd use iconv if available; now we only use iconv for other
character sets). This gives us more consistent results, and in particular
means we now handle BOMs better (at least when using GNU iconv).
* A lot of data labelled as "iso-8859-1" is actually "windows-1252". The two
only differ in characters which are control characters in iso-8859-1, so
assume the latter when we see the former.
scriptindex:
+ Remove special error handling case noting that index=nopos was replaced
with indexnopos - this was removed in 1.1.0 so there's been enough time to
upgrade.
omega:
* Add support for sorting by more than one value - e.g. SORT=+1,-2
* Add $msizelower and $msizeupper which provide access to the lower and upper
bounds on the number of matches.
* Add support for $set{weighting,coord}.
* Add weightingpurefilter option. Normally a query consisting only of filter
terms won't have relevance weights calculated. This new option allows you to
specify a weighting scheme to use for such queries, with the same values
supported as for the existing weighting option. For example,
$set{weightingpurefilter,coord} will weight such queries by how many filter
terms match each document.
* $filters now includes DATEVALUE, which means we'll force the first page when
reloading or changing page starting from existing URLs upon upgrade to 1.4.1,
but the exact same existing URL could be for a search without the date filter
where we want to force the first page, so there's an inherent ambiguity
there. Forcing first page in this case seems the least problematic
side-effect.
* Implement $match command for omegascript. Patch from Richhiey Thomas.
* Add optional prefix argument to $terms.
* $snippet now uses MSet::snippet() instead of the Snipper class.
* Add $contains{STRING1,STRING2}. Contributed by Ayush Gupta.
* Add support for negated boolean filter terms, specified by CGI parameter "N".
* Support a direction prefix on SORT: '+' for ascending, '-' for descending.
SORTREVERSE set to non-0 now flips the direction. Fixes#697, reported by
Andy Chilton.
* Add options argument to $transform.
* Cache compiled regexps used in $transform.
* Add $ord OmegaScript command which returns the Unicode codepoint for the
first character of a UTF-8 string.
* Add $chr OmegaScript command which returns the UTF-8 string for given Unicode
codepoint.
* Add $csv OmegaScript command which escapes a string for use as a field in a
CSV file ("always quote" mode inspired by patch from Gaurav Arora.)
* New $filters encoding which avoids collisions. We also compare CGI parameter
xFILTERS to what $filters would have returned in previous releases, so that
on upgrades old format serialised filters are handled correctly.
* Fix $jsonarray not to prepend ']' to the first array element.
* Skip weighting scheme setup for a pure date range query - it won't be
weighted anyway, so we can avoid having to parse weighting scheme parameters,
etc.
* Use value ranges when date range filtering by value. Should be more
efficient than a MatchDecider, and will automatically take advantage of any
future value range optimisations in xapian-core.
* Add default_db and default_template config options. These allow the default
template and default database name to be set via the config file, rather than
being stuck with the respective defaults of "default" and "query". Fixes
#310, reported by Marco Hennigs.
* Add support for non-exclusive filters. Fixes#234, reported by Thomas
Viehmann.
* Fix handling of multiple P.<prefix> fields - previously only the first seen
was used. These fields are also now taken into account when deciding if the
query has changed. $query now returns an OmegaScript list with one entry for
each CGI parameter passed.
* Allow setting query expansion scheme to "bo1".
* Make the $json and $jsonarray force the text to be valid UTF-8, since
otherwise the output isn't valid JSON.
* Check parameters to $set{weighting,bm25 ...} and $set{weighting,trad ...}
converted OK. Based on patch from Aarsh Shah.
* Add support to $set{weighting,...} for bb2, dlh, dph, ifb2, ineb2, inl2, lm,
pl2 when we're built against a xapian-core which is new enough to have these
schemes.
* Add $snippet to generate a snippet of text tailored to the search.
* Add new $json and $jsonarray OmegaScript commands to support producing JSON
output.
* Add $truncate command which truncates a string after a word.
* Add support for $set{weighting,tfidf} to allow the new TfIdfWeight weighting
scheme to be used.
+ DEFAULTOP now defaults to AND rather than OR, since that matches what pretty
much every search engine does these days. Closes ticket#512.
* Allow mapping a query string prefix to more than one term prefix (which
xapian-core has supported since 1.0.4).
* Add support for search inputs for multiple probabilistic prefixes, with
support for per-prefix stemmers.
* Drop legacy support for handling '.' separated terms in xP - that changed in
Omega 0.9.7, more than 5 years ago now.
* Remove support for OLDP CGI parameter which was superseded by xP
approximately a decade ago, and isn't even documented!
* Drop special handling for R-prefixed terms in $prettyterm - we stopped
generating these in Xapian 1.0.
templates:
* Lower case all HTML tags, attributes and values; explicitly close <option>
tags. Patches from Vivek Pal and Nirmal Singhania.
* Migrate Omega Templates to HTML5. Patch from Nirmal Sighania.
* templates/query: Remove stray double quote from generated URL for spelling
suggestion when THRESHOLD is set. Patch from Nirmal Singhania.
* templates/opensearch: Change response feeds to support OpenSearch 1.1.
Patch from Nirmal Singhania.
* templates/query: Fix setting setting of prefix map for P - in 1.3.2, this
would failed to also search in the subject. Now it also searches in the
subject and topic.
* templates/query:
+ We now map unprefixed queries to include S-prefixed terms to match the
change in omindex to prefixing terms from the title with S. You may want
to make the same update to your own templates.
+ Set up prefixes for 'author:' and 'title:'.
documentation:
* Update links to Xapian website and trac to use https, which is now supported,
thanks to James Aylett.
indexers:
* Fix HTML/XML entity decoding to be O(n) not O(n²) - processing HTML/XML with
a lot of entities is now much faster.
templates:
* Remove unused country code to name maps. These were intended as examples,
but they aren't very useful as such, and really just bloat the templates
needlessly.
documentation:
* Stop maintaining ChangeLog files. They make merging patches harder, and stop
'git cherry-pick' from working as it should. The git repo history should be
sufficient for complying with GPLv2 2(a).
* Clarify help text for omindex --mime-type option.
* docs/omegascript.rst:
+ Fix documentation of $last to say it's the MSet index *one beyond* the end
of the current page. Reported by Andrew Chilton.
+ Clarify that $split and $substr work in bytes. Previously we said
"characters" which could be taken as meaning they work with UTF-8
characters.
+ Update documentation for $filters - it was missing these CGI parameters
from the list of those serialised: COLLAPSE, DOCIDORDER, SORT, SORTREVERSE,
SORTAFTER
+ Explicitly note user can use $setmap to create their own maps.
* docs/overview.rst:
+ SVG extraction is built-in too.
+ Expand paragraph about command `false`. Note the versions where explicit
support was added, and that this will also work with any version on Unix,
where `false` is a command.
+ Document `cdb_dir`.
* docs/cgiparams.rst: Document behaviour if xDB is not set.
* Change "characters" to "bytes" in a few places to clarify that we don't mean
Unicode code points.
indexers:
* omindex:
+ Add '--title-size' option.
+ Handle .oft the same way as .msg - it's some sort of template email, and
has essentially the same format.
omega:
* Make $querydescription ensure the match has been run, so that it includes
filters.
* Avoid $allterms, $cgilist, $filterterms and $terms being O(n²) in the number
of items in the returned list.
* If xFILTERS is not set, don't force the first page as that's unhelpful if
someone fails to set it in their template.
* When environment variable SERVER_PROTOCOL is set to INCLUDED (as it is when
we're being included in a page), we already suppress the HTTP headers, but
now we suppress the blank line after the header too.
* Support option flag_cjk_ngram if built against xapian-core >= 1.2.22.
testsuite:
* Add test coverage for parsing of HTML entities.
build system:
* Fix error reporting if PCRE isn't installed. Fixes#693, reported by lhz7370.
portability:
* Avoid warning when building with glibc >= 2.21.
* Don't provide our own implementation of sleep() under __WIN32__ if there
already is one - mingw provides one, and in some situations it seems to clash
with ours. Reported to xapian-discuss by John Alveris.
* Stop trying to use O_STREAMING - the patch to implement it was never merged
into the Linux kernel, and I can't find any evidence that other platforms
implement it. The constant value O_STREAMING used now seems to be used for
the part of O_SYNC which isn't covered by O_DSYNC, which seems likely to hurt
performance if anything.

documentation:
* docs/overview.rst: Document 'E' prefixed boolean terms for filtering by
extension (see #668, reported by bramvdh).
* docs/encodings.rst: Add a document about character encoding, as suggested by
James Aylett in #550.
* docs/cgiparams.rst: Improve wording of docs for SORT parameter.
* docs/omegascript.rst: Update documentation references to DATE1, DATE2, and
DAYSMINUS which were renamed in 0.6.x and the compatibility aliases removed
in 1.0.0.
indexers:
* omindex:
+ outlookmsg2html: Fix handling of message/rfc822 subparts.
+ Ignore extensions .msi and .msp, which are Microsoft installer files, but
which libmagic sometimes incorrectly identifies as application/msword.
+ Interpret a command of "false" in "--filter" as meaning to ignore files
with that MIME type.
omega:
* $prettyurl now decodes valid UTF-8 sequences, and some additional ASCII
characters in the path part: []@!$&'()*+.;= (Fixes#550 and #644, reported by
catkin and terencz.)
* $prettyurl now leaves the query and fragment parts of the URL alone and won't
decode an escaped "/" (omindex doesn't create URLs with any of these, so we
only risk breaking other URLs which have them).
* Drop compilation date and time from output when run from the command line -
they prevent reproducible builds and the version number is sufficient
information.
* Handle CGI parameter [=0 as [=1.
templates:
* templates/query: When listing matching terms, don't make the commas italic.
* templates/query: Eliminate blank line before <html>.
* templates/xml: Add XML declaration.
* templates/godmode: Specify charset utf-8 in the content-type.
* templates/xml: Update handling of DATE1, DATE2 and DAYSMINUS which were
renamed in 0.6.x and the compatibility aliases removed in 1.0.0.
build system:
* Link test programs with libtool's '-no-install' or '-no-fast-install', like
we already do in xapian-core, which means that libtool doesn't need to
generate shell script wrappers for them on most platforms.
* configure: Use pkg-config in preference to determine flags needed to
compile and link with PCRE, as this will just work when cross-compiling
(at least under MXE).
* configure: Define MINGW_HAS_SECURE_API under mingw to get _putenv_s()
declared in stdlib.h.
* Enable automake option 'subdir-objects' to avoid warning from newer automake.
portability:
* Add spaces between literal strings and macros which expand to literal strings
for C++11 compatibility.
* Remove 'register' as it's deprecated and clang spits out warnings because of
that. Any modern compiler likely just ignores it as an optimisation hint
anyway.
* Avoid doing link tests with libmagic in configure as they fail on mingw due
to not automatically picking up libraries which libmagic itself depends on.
indexers:
* omindex:
+ Work around libmagic returning a MIME content-type of "Composite Document
File V2 Document[...]" or "application/CDFV2-corrupt" by returning a more
suitable filetype based on looking at the file's extension.
+ The starting URL wasn't previously URL encoded. In 1.3.2, this will be
fixed by URL encoding it as we do for the rest of the path, for the 1.2
branch we only URL encode it if it contains a character <= 31 or at least
one of '#', '%', ':' or '?'. This avoids a one-off reindex of every
document in the database in cases which work OK in practice.
+ When we skip a file because it exceeds the configured size limit, include
that size limit in the message.
omega:
* Add support for setting the query expansion scheme to use.
portability:
* Don't compile in unixperm.cc - it isn't currently used, and it fails to build
with mingw. (fixes#635, reported by Alexis Denis)
* Fix warning when built with GCC 4.7.2 using -Os.
* Removed unused inline function, fixing compiler warning.
documentation:
* docs/overview.html: Add Abiword as an example use of --filter, based on patch
from Frank J Bruzzaniti (fixes#383).
portability:
* Fix "no previous declaration" warning on platforms which don't have
mkdtemp().
indexers:
* omindex:
+ Fix off-by-one when finding documents to delete which would sometimes cause
omindex to fail to delete documents from the database when they weren't
refound during an index update.
+ Decode dates in xlsx files.
+ Ignore extensions 'adm', 'cur', and 'ico' by default.
+ Group-readable files which are owner-readable but not world-readable should
still get a "readable by owner" term added. Reported by Emmanuel Garette.
build system:
* Compress source tarballs with xz instead of gzip.
* configure: Sync compiler warning flag machinery against xapian-core. The
changes are special handling for clang, passing -fshow-column where
supported, and handling for new warning flags in GCC 4.6 and 4.7.
Omega 1.2.15 (2013-04-16):
omega:
* Don't pointlessly link utf8convert.o into the omega CGI.
Omega 1.2.14 (2013-03-14):
indexers:
* omindex:
+ Correct "max" -> "min" when reserving space for shared strings in .xlsx
files. This just means we now reserve a more appropriate amount of space
to start with.
+ Ignore .com files by default.
Omega 1.2.13 (2013-01-09):
indexers:
* omindex:
+ Extracting text using external filters now works for filenames containing a
newline character - previously the newline got lost during escaping for the
shell.
+ Fix segfault when -F option without a ':' is passed.
+ Skip a file if we get a read error while calculating the MD5 checksum (used
for duplicate detection) - previously we used a checksum of the file up to
that point.
+ Avoid rereading SVG and Atom files when we calculate their MD5 checksums.
+ Improvement --help output and man page, most notably:
- Say explicitly that --sample-size accepts the same formats as --max-size.
- Note default size limit on files to index is unlimited.
+ When generating a sample for a CSV file, limit the size we pre-allocate to
the CSV file size if that's smaller than the requested sample size, in case
the user sets that limit very high.
omega:
* Fix to decode %-encoded character at the end of the query string.
Omega 1.2.12 (2012-06-27):
No changes since 1.2.11 except to bump the version - this release was made to
fix an incorrect library version information update in xapian-core 1.2.11.
Omega 1.2.11 (2012-06-26):
indexers:
* Change HTML parser's handling of multiple <body> tags and of text outside of
<body> to match the behaviour of modern web browsers. (ticket#599)
* omindex:
+ Add command line option to control the size of the document sample stored.
Patch from Mihai Bivol.
+ Rework .xlsx parsing to substitute the shared strings into the positions
they are used in, so that the sample actually matches what appears in the
spreadsheet, and to index calculated cell contents.
+ Improve handling of headers and footers in OpenDocument documents.
+ pdftotext outputs a formfeed between each page, which messes up our "empty
body" check, so trim any trailing formfeeds before this check.
Omega 1.2.10 (2012-05-09):
indexers:
* Add support for CDATA to HTML/XML parser.
* omindex:
+ Add --max-size option, based on patch from ndaley in ticket#587.
+ Add support for atom feed files, patch from Mihai Bivol in ticket#595.
+ If the document with the highest existing docid before the run was updated,
we were reporting it as "added", but now we correctly report it as
"updated". (Backported from 1.3.0).
+ Catch and report std::exception explicitly, so failing to allocate memory
is no longer reported as "Unknown exception". (Backported from 1.3.0).
Omega 1.2.9 (2012-03-08):
documentation:
* docs/overview.html:
+ Document that libmagic is used to determine the MIME type if the extension
isn't known. Partly addresses ticket#569.
+ We now limit time as well as CPU and memory for external filters.
indexers:
* Our HTML parser now ignores sections bracketed by <!--UdmComment--> and
<!--/UdmComment-->, like we already do for <!--htdig_noindex-->.
* omindex: Add more extensions to the default ignore list: bin dat db fon jar
lnk pyc pyd pyo sqlite sqlite3 sqlite-journal tmp ttf
The rlimit issue adressed in patches ac,ad,ae was already addressed in
release 1.0.11, so remove them.
Omega 1.0.18 (2010-02-14):
indexers:
* Make the default charset "utf-8" not "UTF-8" as we lower case explicitly
specified character sets to compare to see if we need to reparse. Previously
XML documents which explicitly specified their character set as UTF-8 would
cause needless restart or the parser.
* omindex:
+ Increase the wdf boost for the document title from 2 to 5, since 2 isn't
really enough.
* scriptindex:
+ Don't abort with "Unknown Exception" if indexing is disallowed or we hit
</body> for a document which had an overridden character set. Fixes
ticket#410.
Omega 1.0.17 (2009-11-18):
indexers:
* omindex:
+ On Linux, change the memory limit on external filters to use _SC_PHYS_PAGES
since _SC_AVPHYS_PAGES excludes pages used by the OS cache and so will
often report a really low value. Fixes Debian bug#548987 and ticket#358.
+ Fix likely crash when reading output from external filter program if read()
is interrupted by a signal.
+ Fix potential crash when indexing PostScript files (fixed by using delete[]
(not delete) for array allocated by new[]).
testsuite:
* utf8converttest: Charset "8859_1" isn't understood by Solaris libiconv, and
isn't a standard charset name, so just test it when using our built-in
converter and GNU libc.
portability:
* Fix build failure on Mac OS X 10.6.
* Also check for socketpair() in -lxnet if it isn't found without, which
enables resource limits on external filter programs called by omindex on
Solaris, and possibly some other platforms. Fixes ticket#412.
general:
* omegascript.vim: The list of OmegaScript commands in the vim mode was rather
out of date, and a few commands were misclassified. Fix both problems and
avoid future recurrences by automatically generating those lists from the
command list in query.cc.
documentation:
* omegascript.html: Document that $date uses UTC. (ticket#314)
templates:
* query: Link to "xapian.org" rather than "www.xapian.org".
* inc/toptermsjs: Use double-quotes rather than single quotes for parameter
values on the <script> tag.
portability:
* omindex: Implement correct handling of paths when calling external filter
programs on Microsoft Windows.
indexers:
* omindex: Make sure that output is flushed after every message, not just after
some of them.
portability:
* Avoid infinite loop in omindex and scriptindex when reading files under
Cygwin with automatic end of line translation enabled. This same bug can
also manifest on Unix platforms if the file is truncated by another process
while being read.
* omindex:
+ If the filter program needed for a file format isn't installed, report this
explicitly when skipping subsequent files with the extension instead of
misleadingly reporting "Unknown extension".
+ Make -s actually work as a short-form for --stemmer (as documented by
"omindex --help" and "man omindex").
+ Drop the copyright info from the output of --version as it's perennially
out of date and we don't report it for any other Xapian programs.
* scriptindex:
+ Add new "valuenumeric" action to add a document value using
Xapian::sortable_serialise() to allow numeric sorting (ticket#260).
* $log now retries a partial write, or one interrupted by a system call.
* cgiparams.html: Note the technique of using a stub database file to allow a
default of searching over multiple databases.
* omindex:
+ Add support for indexing Microsoft Office 2007 formats and XPS files
(bug#290).
+ Fix the extraction of metadata from OpenDocument formats.
+ Fix "-l" which would previously always cause a segmentation fault if used
("--depth-limit" wasn't affected).
* Fix to compile when RLIMIT_AS isn't available (as on NetBSD and OpenBSD).
Instead use RLIMIT_VMEM or RLIMIT_DATA if either is available, else don't try
to limit the memory the filter process can use.
Omega 1.0.10 (2008-12-23):
build system:
* This release now uses newer versions of the autotools (autoconf 2.62 ->
2.63; automake 1.10.1 -> 1.10.2). The newer autoconf fixes a regression
in autoconf 2.62 (and so Omega 1.0.7) with detecting the endian-ness of some
platforms.
Omega 1.0.9 (2008-10-31):
documentation:
* docs/overview.html: Document HTML parsing a bit, including robots
meta and htdig_noindex.
omega:
* omega: Catch std::exception and report what its what() method returns.
* omega: Remove undocumented and non-functional support for numeric sorting
via CGI parameter SORT=#<slot> (SORT=<slot> works as before).
build system:
* configure: Sync warning flag handling changes from xapian-core to eliminate
many warnings from GCC 4.3.
Omega 1.0.8 (2008-09-04):
documentation:
* Fix a few typos and improve wording in a few places.
indexers:
* omindex:
+ If the character encoding is specified using <meta http-equiv=...> in an
HTML document then reparse the document if it isn't the encoding we're
already using so that any preceding <title> is converted correctly
(bug#292).
+ Convert text from meta tag parameters to UTF-8 (bug#293).
+ Handle <meta charset="..."> (new in HTML 5).
+ Fix bug in HTML tag parameter parsing which was probably just a small
performance penalty in real world cases, but could perhaps result in
parsing bogus extra parameters in carefully contrived situations.
portability:
* Add missing <signal.h>, noted on FreeBSD by Henrik Brix Andersen.
Each database is created and updated separately using either omindex
or scriptindex. You can search these databases (or any other Xapian
database with suitable contents) via a web front-end provided by
omega, a CGI application. A search can also be done over more than
one database at once.
