* Changed the query grammar to allow "not meta" rather than just "not primary".
It should have been this way all along. What this means is that, previously:
not foo = bar
wasn't legal even though it should have been. Instead, you had to do:
not (foo = bar)

documented to do.)

*******************************************************************************
NEW FEATURES
------------
* The text/enriched attachment indexer that was part of the Mail module was
split off into its own RTF (Rich Text Format) module so stand-alone RTF files
can be indexed.
(This feature shall be known as feature RTF.)
* For search(1) running as a daemon, added code to reset the TCP connection for
bad requests. The reason for doing this is so we don't potentially have a
socket lingering in TIME-WAIT from a client that was too dumb to give us a
valid request in the first place. This helps alleviate denial-of-service
attacks (if that's what's going on).
This came about due to the way Solaris handles TIME-WAIT. Read the new
README.Solaris file for details.
This change has no effect in in Linux 2.2.x kernels since sending a reset on
close by setting SO_LINGER wasn't implemented.
(This feature shall be known as feature RST.)

NEW FEATURES
------------
* search(1) can now be run as a daemon without it automatically putting itself
into the background. This is useful in order to wrap a start script around
it and automatically restart it if it dies for any reason.
Correspondingly, there are 2 new utility scripts: searchmonitor (a process
monitor for search) and searchd (a start/stop script for SysV-like systems).
(This bug fix shall be known as feature NOB.)
* search(1), when run as a daemon, can give away its root privileges if it
started with them. There are now new command-line options of -U, --user, -G,
and --group as well as new configuration variables User and Group.
(This bug fix shall be known as feature GAR.)
BUG FIXES

the number of partial indicies exceeded the maximum number of file
descriptors a process could have open, merging would fail.

*******************************************************************************
NEW FEATURES
------------
* When compiling using g++, added additional compiler options to reduce code
size and slightly improve performance.
(This feature shall be known as feature GPPO.)
BUG FIXES
---------
* Indexing files via standard input where the order of the directories
wasn't "monotonically increasing," didn't work: files ended up in the wrong
directory.
As a beneficial consequence, the -D and -G options and the DirectoriesGrow
and DirectoriesReserve variables are no longer needed.
(This bug fix shall be known as big fix ISI2.)
* Destroying a thread_pool's threads didn't work properly in that the clean-up
function for all threads didn't get called. (This didn't matter for SWISH++
since search(1) never destroys its thread_pool.)

*******************************************************************************
BUG FIXES
---------
* File titles turned to garbage when indexing file incrementally.
(This bug fix shall be known as IIT.)
* option_stream's test main() was incorrectly defined inside the PJL namespace.
(This bug fix shall be know as bug fix OSM.)
* option_stream didn't report an error for an option that required an argument
when no argument was given when said option was the last thing on the commend
line.
(This bug fix shall be know as bug fix OSN.)
CHANGES, file-by-file
---------------------

*******************************************************************************
5.3.3
*******************************************************************************
BUG FIXES
---------
* SIGPIPE wasn't handled at all so a search client that disconnected
unexpectedly could crash the server. Now that this has been fixed, the
server also needs to check the state of the outgoing stream during writes for
an error: if an error occurs, assume the client disconnected from the socket
and stop sending output.
(This bug fix shall be known as bug fix PIPE.)
* On Linux systems, multiple reads from the search daemon timed out sooner than
requested because Linux modifies the timeval struct passed to select() to
reflect the amount of time not slept.
(This bug fix shall be known as bug fix LMR.)
CHANGES, file-by-file
---------------------
* search.c
1. In main(), s/search_options opt/search_options const opt/

* version.h
1. Changed version to "5.3.3".
*******************************************************************************
5.3.2
*******************************************************************************
BUG FIXES
---------
* On some platforms, index(1) would index "0 words" for every file.
(This bug fix shall be known as bug fix IZW.)
* There was a race condition in the search daemon thread pool code whereby the
prototype thread could begin executing before its owning thread_pool was
fully constructed.
(This bug fix shall be known as bug fix TPR.)
CHANGES, file-by-file
---------------------
* encoded_char.h
1. Made encoded_char_range::const_iterator's ch_ and decode() compile

thread for bug fix TPR.
* version.h
1. Changed version to "5.3.2".
*******************************************************************************
5.3.1
*******************************************************************************
BUG FIXES
---------
* Searching with more that two "and" terms caused a core cump. This bug was a
result of the "enhancement" to doing multiple "and" terms in 5.3.
(This bug fix shall be known as bug fix MAT.)

5.3
*******************************************************************************
BUG FIXES
---------
* The weighting of multiple "and" terms has been fixed. Previously, the query:
mouse and computer and keyboard
was parsed and treated as:
(mouse and computer) and keyboard
25% 25% 50%
The problem was that the last term always got 50% of the weighting and the
rest got 50% divided by the number of terms minus 1.
In order to weight all the terms equally, the "and" results for each term are
now saved in a list and then and'ed together at the end.
(This bug fix shall be known as bug fix MAW.)
* The index(1) manual page didn't explicitly state that words are converted to
lower case prior to indexing.

BUG FIXES
---------
* This releases fixes a lot of compile issues (mostly namespaces) with g++ 3.0.
(This bug fix shall be known as bug fix GCC3.)
* The changes to fix the above have apparantly caused bugs in (at least) g++
2.95.3 to manifest themselves:
1. In some cases, the compiler "forgets" that operator<<(
ostream&, string const& ) has been defined. The hack
workaround is to use operator<<( ostream&, char const* ) and
use string::c_str().
2. The compiler "forgets" that stream manipulators have been defined.
The workaround is not to use them. :-(
(This fix shall be known as fix OOS.)
CHANGES, file-by-file

NEW FEATURES
------------
* The indexing code has bee rearchitected to be modular allowing for new file
formats to be indexed directly (without filters). Consequently, the indexing
of HTML files has been turned into a module.
The -e option and IncludeFile variable are now INCOMPATIBLE with previous
releases. Read the updated documentation.
(This feature shall be known as feature MOD.)
* A filter module for mail (and news) files has been added.
(This feature shall be known as feature MAIL.)
* A filter module for manual page files has been added.
(This feature shall be known as feature MAN.)
* For index, a new -A or --no-assoc-meta option and AssociateMeta configuration
variable have been added.
(This feature shall be known as feature AMN.)
* There is a new %E (second-to-last filename extenstion) substitution.
(This feature shall be known as feature 22L.)
* FilterFile configuration lines are now different and INCOMPATIBLE with
previous releases. The @ character no longer does substitutions but merely
marks the target filename. This was done to enable filtering to files having
a fixed name to be able to handle filenames with spaces better.
(This feature shall be known as feature SM2.)
* The search daemon can now answer queries via TCP sockets in addition to Unix
domain sockets.
(This feature shall be known as feature TCP.)
* You can now specify the separator character in search results.
(This feature shall be known as feature SRS.)
* Added parsing of XHTML 1.1 ruby elements.
(This feature shall be known as feature RUBY.)
BUG FIXES
---------
* The index(1) -T option was ignored.
(This bug fix shall be known as bug fix ITO.)
* A configuration file that did not end in a newline would cause a segfault.
(I think: I never tried it, but it looked like a bug to me.)
(This bug fix shall be known as bug fix CNL.)
* Configuration error messages output "(null)" (or seg-faulted) for the
variable name. I don't see how the compiler didn't catch this since the
name_ data member is const and therefore must be initialized in the
constructor.
(This bug fix shall be known as bug fix NVR.)
* Setting the SearchDaemon config. variable to Y didn't allow no command-line
arguments to be given.
(This bug fix shall be known as bug fix DCL.)
* Filter substitution incorrectly rescanned substituted text.
(This bug fix shall be known as bug fix FSR.)
* Several tweaks were made to make SWISH++ compiled under FreeBSD.
(This bug fix shall be known as bug fix BSD3.)
* Added -lnsl for compiling the search daemon under Solaris.
(This bug fix shall be known as bug fix SOL2.)
* Removed some more buffer-overflow bugs.
(This bug fix shall be known as bug fix BOB.)
* Filename patterns didn't match if the wildcard wasn't first, e.g., foo*
(This bug fix shall be known as bug fix WWF.)

conditionally #include'd.
(This bug fix shall be knows as bug fix IDB.)
* The directory separator character ('/' for Unix) is apparantly transformed
into '\' for Windows by the intermediate Windows port of POSIX functions.
However, in the case where '/' is inserted into a string and that string is
printed, the mere printing won't do the transformation.
(This bug fix shall be knows as bug fix WDSC.)
CHANGES, file-by-file

4.7
*******************************************************************************
NEW FEATURES
------------
* Added 'b' and 'B' substitutions for filters that are the base name and base
name minus the extension of a file name, respectively. This is useful when
you need the temporary files created in a location other than where the
originals are, for example when the originals are on a filesystem that you
don't have write access to.
Note that, for consistency, the 'E' substitution has been renamed to 'F'.
This is therefore an incompatible change with previous versions of SWISH++.

4.3.1
*******************************************************************************
BUG FIXES
---------
* Indexing via standard input did NOT index all files: it still required you to
specify extensions via -e. This is totally wrong. It seems it's been wrong
since version 3.1. I'm surprised nobody noticed.

to get the precedence right. :-(
(This bug will be known as bug fix FGP.)
* For 'search', the description of the -p and --word-percent option in the
usage message wasn't printed unless it was compiled as a daemon (and these
options have nothing to do with it being a daemon).

NEW FEATURES
------------
* Generated index files are now approximately 24% smaller.
(This feature will be known as feature SIF.)
BUG FIXES
---------
* When index(1) generated partial indicies, it never removed words that
occurred in more files than the allowable percentage.
(This bug fix will be known as bug fix PIR.)
* The -T/--temp-dir options were left out of the option specification for
index(1) so you could never specify these options on the command line.
(This bug fix will be known as bug fix TDO.)
* Added a call to setsid() for becomming a search daemon. It should have been
there all along.
(This bug fix will be known as bug fix SID.)
CHANGES, file-by-file
---------------------
* bcd.c
* bcd.h
1. Added these files for feature SIF.
* config.h

* file_list.c
1. Rewrote file_list::calc_size() for bug fix PIR. I was
counting spaces. Why? I don't know. There were never any
spaces in the file list data. As far as I can tell, this
never worked.
2. Rewrote file_list::const_iterator::operator++() to parse
index file word data in new format for feature SIF.
* file_list.h
1. Performed following substitution:

1. In merge_indicies() and write_word_index(), changed the
format in which the index file is written from ASCII to BCD
for feature SIF.

broken. While it appeared to merge properly, I don't think
it ever threw out words that exceeded any thresholds. I
rewrote chunks of it for bug fix PIR.
3. Factored out some code into a new is_too_frequent() function.
4. In write_meta_name_index(), changed the ASCII numerical
output to BCD for feature SIF.

since it wasn't saving the exit code and always exiting with 0
(I don't know why.) This was done for feature MSD.

*******************************************************************************
NEW FEATURES
------------
* All executables now accept alternate long ("GNU-style") command-line options.
(This feature will be known as feature LOPT.)
* Added -? option to print usage ("help") message.
(This feature will be known as feature HELP.)
* Added new -h option and HTMLExtention configuration variable to allow
filename extensions that are to be treated as HTML to be specified.
(This feature will be known as feature HEXT.)
* In 'search', allow max-results to be specified as 0. This allows the -R
option to be eliminated.
(This feature will be known as feature MR0.)
* Added code to max-out various resource limits since SWISH++ is resource-
intensive. This may alleviate out-of-memory conditions on some platforms.
(This feature will be known as feature MAXR.)
* Added code to map ISO 8859-1 (Latin 1) characters to their closest ASCII
equivalent so that they are treated eactly like character entity references.
This should also improve use of SWISH++ in other languages.
(This feature will be known as feature ISOMAP.)
BUG FIXES
---------
* Feature CLASS has had a subtle bug in it since its inception in version 2.0.
It was over-zealous in closing HTML elements. For example, given:
<TABLE>
<TR> <!-- 2 -->
<TD> <!-- 1 -->
<TABLE> <!-- 0 -->
<TR>
<TD>
Hello
</TD>
</TABLE> <!-- trouble -->
</TD>
</TABLE>
The "trouble" tag should have stopped closing elements at tag "0" but it kept
closing elements "1" and "2" because </TD> and </TR> have </TABLE> in their
set of close tags.
The fix is to make a tag check to see whether the element it's closing is its
own start tag: if so, stop.
(This bug fix will be known as bug fix CLASS1.)
* Really long start tags, those with lots of attributes, exceeding 128
characters, would cause a buffer overflow and, occasionally, a core dump.
The fix is to change the way getting the name of tags is done.
(This bug fix will be known as bug fix RLST.)

3.0.3
*******************************************************************************
NEW FEATURES
------------
* A -H option has been added to 'index' to dump the built-in set of recognized
HTML elements to standard output (so you can check to see if a certain tag is
recognized or not).
(This feature will be known as feature OPTH.)
* Boolean configuration file variables now accept "on" and "off" values.
(This feature will be known as feature ON_OFF.)
BUG FIXES
---------
* There was a small memory leak when indexing META names.
(This bug fix will be known as bug fix ML1.)
* Reporting errors in a configuration file says what line number the error is
on. However, the same error-reporting code is also used to print errors when
command-line arguments are invalid. The line number variable wasn't cleared
so it would print an erroneous line number for an invalid command-line
option.
(This bug fix will be known as bug fix CLN.)
* Parsing of Boolean values in configuration files was completely broken.
(This bug fix will be know as bug fix PBV.)
* WWW::extract_description() did it wrong for ALT attributes with an empty
value, i.e., ALT="".
(This bug fix will be known as bug fix ADE.)

1. In main(), performed following substitutions for command
line argument variables:
s/char*/char const*/
* search.c

NEW FEATURES
------------
* SWISH++ now allows flexible file filtering for extraction and indexing.
(This feature will be known as feature FFF.)
* SWISH++ now allows configuration files since they were necessary for feature
FFF. If I had to add them, I might as well do it right.
(This feature will be known as feature CONF.)
* SWISH++ now compiles and runs under Windows (95/98/NT).
(This feature will be known as feature WIN32.)
* 'index' now accepts a -T option that allows the directory to use for
temporary files to be specified.
(This feature will be known as feature TEMP.)
* 'index' and 'extract' now report the number of files examined in addition to
the number indexed or extracted, respectively.
(This feature will be known as feature EXAM.)
BUG FIXES
---------
* In the admitedly rare case of a malformed HTML file ending in a '<' character
(without a newline, i.e., '<' is the *VERY* last character in the file),
'index' would core-dump.
(This bug fix will be known as bug fix EGT.)

NEW FEATURES
------------
* SWISH++ can now selectively not index text in HTML files within HTML elements
that are members of specified classes.
(This feature will be known as feature CLASS.)
* The 'search' command now offers optional stemming. Indexing is unaffected.
(This feature will be known as feature STEM.)
* In all earlier versions, the number of total words reported was actually the
total number of words indexed; now, it is the total number of words parsed
and the former "total words" is now reported as the number of words indexed.
(This feature will be known as feature NTW.)
* The 'search' command now outputs an additional comment "results" followed by
the total number of search results. Additionally, there is a new -R command-
line option to print this alone.

1.7
*******************************************************************************
NEW FEATURES
------------
* Since version 1.4, SWISH++ indexed the text in the ALT attributes of AREA and
IMG elements. SWISH++ now adds a few attributes. The complete set is:
Attribute Element
--------- -------
TITLE any
ALT AREA, IMG, INPUT
STANDBY OBJECT
SUMMARY TABLE
(This feature will be known as IEA.)
* Added Word_Min_Vowels to config.h so vowel checks can be disabled (or made
more stringent).
(This feature will be know as feature WMV.)
BUG FIXES
---------
* When a given word appeared through many files, its ranks came out rather
"flat" in the search results. This has been fixed.
(This bug fix will be known as bug fix 10K.)
CHANGES, file-by-file
---------------------

static ext_proc_map const ext_procs;
It should have been there all along.
* html.c
1. Added declarations for find_attribute(), skip_html_comment()
and skip_html_tag() to the top of the file. They should
have been there all along.
2. In convert_entity(), added missing 'const' to declaration:

1.6
*******************************************************************************
NEW FEATURES
------------
* The value of the CONTENT attribute for META elements can now selectively be
indexed based on the value of the NAME attribute, either by explicit
inclusion or exclusion.
(This feature will be known as feature MIE.)
* The WWW Perl library has a new function, extract_meta(), that can extract the
value of the CONTENT attribute from a META element having a given NAME
attribute from an HTML file.
This can be used to display meta information in search results, e.g., for
a given search result, also display its author, publication date, etc.
(This feature will be known as feature EMC.)
BUG FIXES
---------
* If parentheses were used in conjunction with 'not' in a query involving meta
names, it didn't work, e.g.:
search author = not hawking
worked as expected, but:
search author = not ( hawking )
didn't even though it is (supposed to be) equivalent.
(This bug fix will be known as bug fix MNP.)
CHANGES, file-by-file
---------------------
* html.c

recursive call of parse_query() for bug fix MNP.
* version.h
1. Updated version to "1.6".
* WWW.pm
1. Added extract_meta() function for feature EMC.
2. Rewrote extract_description() in terms of extract_meta().
*******************************************************************************
1.5.1
*******************************************************************************
NEW FEATURES
------------
* Both 'index' and 'extract' now have a new verbosity level 4 that prints
filenames that are not indexed or extracted, respectively, and why. (This
feature was added to help fix bug fix HTH.)
(This feature will be known as feature IEV4.)
* The 'httpindex' script's -v option now works exactly like that of 'index'.
(This feature will be known as feature HTV.)
BUG FIXES
---------
* META attribute name parsing had a bug where the find_attribute() function
could occasionally run past the 'end' of where it was supposed to look.
(This bug fix will be known as bug fix FAE.)
* The 'httpindex' script would hang if it told 'index' to index a file and,
for whatever reason, 'index' couldn't since 'index' would silently skip the
file.
(This bug fix will be known as bug fix HTH.)
* The WWW::extract_description() function returned the first
$description::chars characters of a file untouched if the file did not end
with one of the filename extensions matched by the pattern
/\.(?:[a-z]?html?|txt)$/i. What it should do is return a null description.
(This bug fix will be known as bug fix EDN.)
* The 'httpindex' script didn't test the extracted description to see if it is
null: if it is, it should not attempt to overwrite the original file with the
description and instead just delete the file.
(This bug fix will be known as bug fix HTND.)
CHANGES, file-by-file
---------------------
* extract.c
1. In main(), changed upper-bound for verbosity to 4 for
feature IEV4.

incremented past 'end' (as it sometimes incorrectly was) for
bug fix FAE.
* httpindex.in
1. Performed following substitution:
s/-v3/-v4/
for bug fix HTH.
2. Added code to test the extracted description to see if it is
null for bug fix HTND.
3. If a file can not be overwriten with its description (using
the -d option), a warning is now merely issued rather than
dieing as in version 1.5.
4. Added code for feature HTV.
* index.c
1. Same as extract.c #1.
2. Same as extract.c #2.
3. Same as extract.c #3.
* man/man1/extract.1
* man/man1/index.1
1. Updated description for feature IEV4.

systems.
* INSTALLATION
1. A third prerequisite of Perl 5 was added for feature HTTP.

*******************************************************************************
1.4.1
*******************************************************************************
BUG FIXES
---------
* The META names words were associated with was completely wrong. It worked in
a small number of test cases (my original test cases -- figures), but not in
the general case.
(This bug fix will be known as bug fix MID.)
* In 1.4, a given word could be associated with at most 1 meta name per file.
This limitation was an oversight. It has been corrected.
(This bug fix will be known as bug fix MMM.)
CHANGES, file-by-file
---------------------
* extract.c
1. Performed following substitution:
s/string_set.h/my_set.h/

* index.c
1. Same as file_list.c #1.

numeric ID for META name for bug fix MID.
7. In write_word_index(), same as #4.
* index.h

* less.h
1. Added explicit default constructor since g++ 2.8.0 complains
if it isn't there and you try to define a "const less"
object.
* my_set.h
1. This file was renamed from string_set.h.
2. Made string_set class generic for any type T since we now
use a set< short > in word_info::file.
3. Changed declaration of string_set to be simply:
typedef my_set< char const* > string_set;
* postscript.h
1. Same as extract.c #1.

2. Same as file_list.c #1.
3. In dump_single_word(), performed following substitution:
s/less< char const* >/less< char const* > const/
since it can be const (and everything that can be const
should be).
4. In dump_word_window(), same as #3.
5. Added get_meta_id() function for bug fix MID.
6. In parse_meta(), performed following substitution:
s/::distance( meta_names.begin(), found.first )

* word_info.h
1. Changed word_info::file struct to include a set of meta-IDs
for bug fix MMM.
2. Changed word_info::file struct to use shorts for occurrences
and rank to conserve memory (since additional memory is now
being taken up by the set of meta-IDs).
3. Gave the word_info::file struct 3 speparate constructors so
the minimal amount of code is executed depending on how an
object is constructed.
*******************************************************************************
1.4
*******************************************************************************
NEW FEATURES
------------
* SWISH++ now indexes and can search META data.
(This feature will be known as feature META.)
* SWISH++ now indexes the words in ALT attributes within AREA and IMG elements.
(This feature will be known as feature ALT.)
* SWISH++ can now index files and directories specified via standard input
instead of via the command line. When doing this, extensions of files to
index need not explicitly be specified via the -e option, i.e., 'index'
assumes you know what you're doing when specifying filenames.
(This feature will be known as feature ISI.)
* For both 'index' and 'extract', a new -r command line option was added to
suppress recursively indexing files in subdirectories. This option is most
useful in conjunction with the new ISI feature.
(This feature will be known as feature CLR.)
* Added an optimization option for detemining whether a character is a "word
character" by eliminating the call to strchr() in is_word_char(). This
yields about a 10% performance improvement during indexing.
(This feature will be known as feature WCO.)
* The code for the 'index' was profiled and a couple of performance tweaks were
made yielding about a 7% performance improvement.
(This feature will be known as feature PPT.)
BUG FIXES
---------
* A small bug whereby the last word of a file was not indexed if the last line
didn't end in a newline (or a whitespace character in general) was fixed.
(This bug fix will be known as bug fix ILW.)

the map.
* ext_proc.h
1. Performed following substitution:
s/map_type::const_iterator i/map_type::const_iterator const i/
It should have been that way all along.
* extract.c

feature META.
2. Added definition of meta_names for feature META.
3. In main(), added code for feature ISI.
4. In main(), added handling of new -r option for feature CLR.
5. Refactored do_file() by splitting out the actual word
indexing part into a new function index_words() for feature
META. The index_words() function is now also called by
parse_html_tag() to index the words in the CONTENT attribute
of META elements.
6. In do_file(), replaced 3 function calls to strcmp() to see
if a file is an HTML file with a callto a new, inlined
is_html_ext() function for feature PPT.
7. In index_words(), redid main 'while' loop and added 'if's
for bug fix ILW.
8. In index_words(), added 'if' so as not to parse '<' as the
start of and HTML tag if meta_index >= 0 for feature META.

sequence with a new FOR_EACH or TRANSFORM_EACH macro. (I
got tired of typing.)
D. In rank_full_index(), moved the code to compute the ranks
AFTER the tests to see whether a word occurs too frequently.
It was originally placed before since file_count needed to
be calculated, but I realized this is known ahead of time as
simply info.files_.size().
E. Added write_meta_name_index() for feature META.
F. In write_full_index(), added call to write_meta_name_index()
for feature META.

s/parse_primary/parse_meta/
for feature META.

and added 'if's for bug fix ILW.
* token.c
1. Reworked token::hold() to accomodate more than one
put_back() in a row for feature META since parse_meta()
requires two look-ahead tokens.

1.3.2
*******************************************************************************
BUG FIXES
---------
* The ignore stop words feature (feature ISW) added in version 1.2 was slightly
broken in 1.2.1; it was "fixed" in 1.2.2 (bug fix ISW2), but not quite in
that if left hand side of a query was ignored, thw whole thing was.
(This bug fix will be known as bug fix ISW3.)
* In 'index', the check for whether filename extensions were supplied was too
early in the code so the -S option didn't work.
(This bug fix will be known as bug fix CFE.)
CHANGES, file-by-file
---------------------
* config/man.mk
1. Made "make dist" make the manual pages in PDF format in
addition to text format.
* index.c
1. Relocated code to check whether filename extensions were
supplied for bug fix CFE.
2. In main(), used an ostream_iterator() to dump stop words.
3. In do_file(), split tests for stop-words into two separate
'if' statements so to_lower() isn't called unless absolutely
necessary.
* search.c
1. In parse_query(), redid ignore-handling code for bug fix
ISW3.
2. In main(), used an ostream_iterator() to dump stop words.

millions, ninteen, second, seconds, seventeen, sixteen,
tens, third, thirteen, trillions.
* util.c
1. In is_ok_word() on line 192, changed floating point
calculation to integer by multiplying LHS by 100 to increase
performance.
2. On the same line, performed the followingg substitution:
s/>=/>/
so the code matches the documentation that says, "...
contains more than a third capital letters ..."
* version.h
1. Updated version to "1.3.2".
* www_example/search.cgi
1. Removed extraneous 'o' (optimize) options from regular
expressions.
* www_example/WWW.pm
1. Added GNU Public Licensce notice at top.
2. In trim_whitespace(), used map() rather than a for loop.

BUG FIXES
---------
* Unbeknownst to me, I introduced a bug in 1.2.2 that broke wildcard searches.
(Doh!) This has been fixed.
(This bug will will be known as bug fix WCF.)
CHANGES, file-by-file
---------------------
* man/man1/search.1
1. Make it explicitly clear that wildcards are not permitted
for the -d and -w options.
* token.c
1. Moved the line:
::strcpy( t.lower_buf_, to_lower( t.buf_ ) );
before:

1. Updated version to "1.3.1".
*******************************************************************************
1.3
*******************************************************************************
NEW FEATURES
------------
* In "search," a "window" of words can be dumped around the query words.
(This feature will be known as feature DWW.)
* In "search," the -d option to dump the index for a word now dumps all the
query words instead of a single word. Additionally, a stop-word used to
print "stop-word"; now it prints "# ignored: " followed by the word.
(This feature will be known as feature DQW.)
* In "search," the -d option to dump the index for a word now prints the
comment:
# not found: word
if 'word' is not found in the index.
(This feature will be known as feature NFW.)
CHANGES, file-by-file
---------------------
* directory.c
1. Changed order of #include's putting direct.h last so that it
compiles OK under FreeBSD 2.2.7.

3. In main(), performed the following substitution:
s/dump_entire_index || dump_stop_words || dump_word
/dump_entire_index || dump_stop_words/
for feature DQW since the -d option no longer takes an
argument.
4. In main(), added code to handle new -w option for feature
DWW.
5. In main(), added 'while' loop to code to dump multiple words
for feature DQW.

*******************************************************************************
1.2.2
*******************************************************************************
NEW FEATURES
------------
* A heuristic was added not to index a word if it contains more than a
threshold number of consecutive punctuation characters.
(This feature will be known as feature MCP.)
* Files can now be indexed by exclusion of filename extensions rather than by
inclusion via a new -E command-line option.
(This feature will be known as feature EFE.)
BUG FIXES
---------
* The ignore stop words feature (feature ISW) added in version 1.2 was slightly
broken in 1.2.1 in that the list of ignored words was no longer reported.
(This bug fix will be known as bug fix ISW2.)
CHANGES, file-by-file
---------------------
* config.h
1. Performed following substitution:
s/Word_Hex_Min_Size/Word_Hex_Max_Size/
The original name was inconsistent with the other parameters.
2. Added "Word_Max_Consec_Puncts" for feature MCP.

s/install.sh/install-sh/
so some versions of make don't get confused with the .sh
suffix and try to build it.
* extproc.c
1. Added definitions for WEXITSTATUS and WIFEXITED if not
defined on a particular system.
* extract.c
1. Corresponding change for config.h item 1.

3. In parse_primary(), added code formerly in is_stop_word()
here for bug fix ISW2.
* token.c

for bug fix ISW2. Previously, acronyms were not recognized
in lower case and keywords ("and," "or," and "not") were not
recognized in upper case.
2. Added code to make a copy of the token string in all lower
case. This is still needed for stop-word determination.
* token.h
1. Added second buffer to hold all-lower-case version of token
text for bug fix ISW2.

*******************************************************************************
1.2.1
*******************************************************************************
NEW FEATURES
------------
* In "search," the original -d option that used to dump the entire index now
dumps the index entry for a single word. Correspondingly, a new -D option
now does what -d used to do.
(This feature will be known as feature DSW.)
* In "search," the dump of the index entries now includes the rank.
(This feature will be known as feature DIR.)
BUG FIXES
---------
* Numeric entity references were not converted to their ASCII equivalents. (I
don't know how I missed this.)
(This bug fix will be known as bug fix NER.)
* A search query that contained only stop-words returned all files (up to the
specified limit or default maximum).
(This bug fix will be known as bug fix RSW.)
CHANGES, file-by-file
---------------------
* config/config.mk
1. Added comment at top to remind people that they must do a
"make distclean" before recompiling if they change any
definitions.
2. Performed the following substitution:
s!/usr/ucb/install!$(ROOT)/install.sh!

so as to distinguish them from the newly-added num_entities[].
3. Added:
"ETH", 'D', "eth", 'd',
to char_entity_table[].
* entities.h
1. Added:
extern char const num_entities[ 256 ];
for bug fix NER.

* html.c
1. Corresponding changes for entities.c item 2.
2. Made use of new num_entities[] for bug fix NER.
* index.c
1. On line 400, performed the following substitution:
s/*lower_word/*const lower_word/
It should have been that originally.
* install.sh
1. Created this shell script to use for installs instead of
having to rely on the OS having a "Berkeley-esque" install
command.
* man/man1/search.1
1. Changed description for feature DSW.
* search.c
1. Added new find_result_type typedef.
2. Added a new dump_single_word() function for feature DSW.
3. Added "bool &ignore" parameter to parse_query() and
parse_primary() functions for bug fix RSW.
4. Factored out code that determines whether a word was indexed
or not into a new function is_stop_word().
5. In main(), added code for feature DSW.
6. In main(), added code for feature DIR.
7. In parse_query(), added code to ignore stop-words properly
for bug fix RSW.
8. On line 423, performed following substitution:
s/iterator/const_iterator/
It should have been that originally for "const correctness."
9. In parse_primary(), made use of new is_stop_word() function
corresponding to item 4.
A. In parse_primary(), added code under "not" case to check to
see whether the primary should be ignored for bug fix RSW.
B. In usage(), added text to usage message for feature DSW.
* util.c
1. On line 65, performed following substitution:
s/STATIC_CAST/REINTERPRET_CAST/
It should have been that originally.

1. Updated version to "1.2.1".
* www_example/search.cgi
1. Added "&'" characters to those that are not stripped from
the query.
2. Added:
next if /^#/;
so as to ignore comments we know nothing about that future
releases of SWISH++ may emit.
*******************************************************************************
1.2
*******************************************************************************
NEW FEATURES
------------
* SWISH++ now stores the list of stop-words in the generated index file so they
can be ignored on searches later. Previosuly, using a stop-word in a query
would always yield 0 results since the stop-word isn't in the index. After
thinking about it, this is just plain stupid.
(This feature will be referred to as feature ISW.)
* You can now specify the number of files to reserve space for on the command
line for "index" overriding the default.
(This feature will be referred to as feature ICF.)
* You can now specify the number of lines to look into a file for HTML <TITLE>
tags on the command line for "index" overriding the default.
(This feature will be referred to as feature ICt.)
* Added default values to usage messages.
(This feature will be referred to as feature UDV.)
BUG FIXES
---------
* The detection of malformed queries was completely broken. I don't see how
this went undetected for this long.
(This bug fix will be referred to as bug fix DMQ.)
* In the example WWW.pm Perl library, not all the "Unix-unfriendly" characters
were stripped from filenames upon upload.
(This bug fix will be referred to as bug fix UUC.)

2. Added:
int num_files_reserve = Files_Reserve_Default;
for feature ICF.
3. Added:
int num_title_lines = Title_Lines_Default;
for feature ICF.
4. Performed following substitutions:
s/total_words/num_total_words/
s/unique_words/num_unique_words/
5. Performed following substitution:
s/"the.index"/Index_Filename_Default/
6. Added 'F' option to command line parsing code and usage
message for feature ICF.
7. Added 't' option to command line parsing code and usage
message for feature ICt.
8. In do_file(), added code to check whether a word is a
stop-word explicitly for feature ISW. This corresponds to
the change for util.c item 2.
9. In merge_indices(), removed extra_stop_words and am now
using stop_words since they all have to be written to the
index file together. This was done for feature ISW.
A. In merge_indices(), added code to write additional header
information for the stop-words.
B. In rank_full_index(), now add computed stop-words to global
set so they can all be written to the index file together.
This was done for feature ISW.
C. In write_full_index(), added code to write additional header
information for the stop-words.
D. Added code to usage() for feature UDV.
* Makefile

1. Added description of new index file format for feature ISW.
* search.c
1. Added definitions:

string_set stop_words_found;
for feature ISW.
2. Performed following substitution:
s/"the.index"/Index_Filename_Default/
3. In main(), added code for new -S option to dump the stop-
words from an index file. This was done for feature ISW.
4. In main(), added test of EOF for the query_stream to ensure
the entire query is parsed successfully for bug fix DMQ.
5. In main(), added code to output stop-words ignored in the
query for feature ISW.
6. In parse_query(), changed:

if ( !parse_primary( query, temp1 ) )
return false;
for bug fix DMQ.
7. In parse_optional_relop(), changed code in default case by
adding a check for a ')' token for bug fix DMQ.
8. In parse_primary(), added code to search stop-words for a
word in a query and ignore it for feature ISW.

following substitution:
s/lparen_token/rparen_token/
for bug fix DMQ.
A. Added code to usage() for feature UDV.
* stop_words.c
1. Added "let's".
2. In constructor, changed use of "new" to "strdup".
3. Change corresponding to util.c item 3.

information of an index file for feature ISW.
2. In is_ok_word(), removed check for stop-words for feature

differently than either "index" or "extract" does.
3. Added function:
char const *to_lower( char const *s )
for feature ISW.
4. Added "missing":
#include <cstring>

1. Change corresponding to util.c item 1.
2. Change corresponding to util.c item 2.

the regular word index (0) and the new stop-word index (1).
2. Moved index file header parsing code into a new function
get_index_info() in util.c for feature ISW.
* word_index.h
1. Added int parameter to both constructor and set_file_index()
since a word_index is now used for both the regular word
index (0) and the new stop-word index (1).

stripped from filenames for bug fix UUC.
* www_example/search.cgi
1. Added code to handle ignored words returned by "search" for

*******************************************************************************
1.1
*******************************************************************************
