-This is my current list of bugs (not complete, but what I've had time
-to note). Hope it helps:
-
-"perl -e die" will cause a seg-fault
-
-$. is not updated
-
-Memory leak for anonymous arrays:
-	while(1) { @a = (1, 2, 3, [4, 5], 6); @a = (); }
-	Will keep allocating and not freeing memory.
-
-"perl -e 'sub foo {print 1} foo'" should either complain or call foo,
-	but does neither. Or, did Larry not impliment the &-less
-	function calling that he was talking about?
-
-"perl -le 'sub foo {1} $a = \&foo; print &{$a}; print &{$a} + 1'" should
-	not fail to parse.

+
+Since I've received requests to do so, I'm posting the cperl-mode.el
+file.  This allows Emacs (both version 18 and 19) to do nice things
+when editing Perl code.  Indentation works well, and it doesn't get
+confused like the perl-mode.el that comes with Emacs 19.
+
+Install this file as cperl-mode.el, and add the following to your
+.emacs file:
+
+(autoload 'perl-mode "cperl-mode" "alternate mode for editing Perl programs" t)
+
+This cperl-mode.el is not exactly the same as when it was originally
+posted here.  I made the following changes:  perl-mode is an alias for
+cperl-mode, and the major mode name is perl-mode, not cperl-mode.
+This is so it is easier to use with Emacs 19.  I suppose one could
+install this as perl-mode.el and then not have to put the autoload
+line in (for Emacs 19).
+
+Anyway, I'm not maintaining this, so don't send me bugs.

+| Hi folks
+| 
+| Say, I'm trying to use perldb with emacs.  I can invoke perldb 
+| within emacs ok and get the window *perldb-foo*  but when it asks
+| for "additional command line arguments" , no matter what I give it
+| I get the error message   Symbol's function definition is void:  make-
+| shell.
+| 
+| The debugger , by itself, works fine but wanted to try out perldb in
+| emacs.
+
+This is a symptom of using Emacs 19.xx with perldb.el which was originally made
+for emacs version 18.xx.  You can either install the emacs19 replacement for
+perldb that hooks it in with GUD (grand unified debugger), or apply the patches
+that I picked off of the net (I use the perldb replacement that uses GUD
+myself):

+XMessage-ID: <CA7uq9.30J@murdoch.acc.Virginia.EDU>

+XHere are my patches to perldb.el (the perl debugger mode that comes
+Xwith perl 4.0xx).  Basically, all I've done is to hack perldb.el to
+Xuse comint.el stuff rather than the old shell.el stuff (i.e. change
+Xshell-mode-map to comint-mode-map).
+X
+XI've been using my patched version without problem, but if anyone sees
+Xsomething I've missed, please post or send e-mail.
+X
+X				Thanks,
+X						Dave

+XA The Clone of the ndbm library
+X
+X     The sources accompanying this notice - sdbm  -  consti-
+Xtute  the  first  public  release  (Dec. 1990) of a complete
+Xclone of the Berkeley UN*X ndbm library. The sdbm library is
+Xmeant  to  clone the proven functionality of ndbm as closely
+Xas possible, including a few improvements. It is  practical,
+Xeasy to understand, and compatible.  The sdbm library is not
+Xderived  from  any  licensed,  proprietary  or   copyrighted
+Xsoftware.
+X
+X     The sdbm implementation is based on  a  1978  algorithm
+X[Lar78] by P.-A. (Paul) Larson known as ``Dynamic Hashing''.
+XIn the course of searching for a substitute for ndbm, I pro-
+Xtotyped  three different external-hashing algorithms [Lar78,
+XFag79, Lit80] and ultimately chose Larson's algorithm  as  a
+Xbasis  of  the  sdbm  implementation. The Bell Labs dbm (and
+Xtherefore ndbm) is based on an  algorithm  invented  by  Ken
+XThompson, [Tho90, Tor87] and predates Larson's work.
+X
+X     The sdbm programming interface  is  totally  compatible
+Xwith ndbm and includes a slight improvement in database ini-
+Xtialization.  It is also expected  to  be  binary-compatible
+Xunder most UN*X versions that support the ndbm library.
+X
+X     The sdbm implementation shares the shortcomings of  the
+Xndbm library, as a side effect of various simplifications to
+Xthe original Larson algorithm. It does produce holes in  the
+Xpage file as it writes pages past the end of file. (Larson's
+Xpaper include a clever solution to this problem  that  is  a
+Xresult of using the hash value directly as a block address.)
+XOn the other hand, extensive tests  seem  to  indicate  that
+Xsdbm creates fewer holes in general, and the resulting page-
+Xfiles are smaller. The sdbm implementation  is  also  faster
+Xthan  ndbm  in database creation.  Unlike the ndbm, the sdbm

+Xstore operation will not ``wander away'' trying to split its
+Xdata  pages  to insert a datum that cannot (due to elaborate
+Xworst-case situations) be inserted. (It will  fail  after  a
+Xpre-defined number of attempts.)
+X
+XImportant Compatibility Warning
+X
+X     The sdbm and ndbm libraries cannot share databases: one
+Xcannot  read  the  (dir/pag)  database created by the other.
+XThis is due to the differences between  the  ndbm  and  sdbm
+Xalgorithms[2], and the hash functions used.  It is  easy  to
+Xconvert  between the dbm/ndbm databases and sdbm by ignoring
+Xthe index completely: see dbd, dbu etc.

+X  [2] Torek's   discussion   [Tor87]   indicates   that

+X     dbu is a simple database manipulation  program[4]  that
+Xtries to look like Bell Labs' cbt utility. It  is  currently
+Xincomplete in functionality.  I use dbu to test out the rou-
+Xtines: it takes (from stdin) tab separated  key/value  pairs
+Xfor commands like build or insert or takes keys for commands
+Xlike delete or look.

+X
+X     dba is a crude analyzer of dbm/sdbm/ndbm page files. It
+Xscans the entire page file, reporting page level statistics,
+Xand totals at the end.
+X
+X     dbd is a crude dump  program  for  dbm/ndbm/sdbm  data-
+Xbases.  It  ignores  the bitmap, and dumps the data pages in
+Xsequence. It can be used to create input for the  dbu  util-
+Xity.   Note that dbd will skip any NULLs in the key and data
+Xfields,  thus  is  unsuitable  to  convert   some   peculiar
+X_________________________
+X
+X  [4] The dbd, dba, dbu utilities are quick  hacks  and
+Xare  not  fit  for  production use. They were developed
+Xlate one night, just to test out sdbm, and convert some
+Xdatabases.

+X     I have also included a copy of the dbe  (ndbm  DataBase
+XEditor)  by  Janick Bergeron [janick@bnr.ca] for your pleas-

+Xity.

+X     dbm.[ch] is a dbm library emulation on top of ndbm (and
+Xhence suitable for sdbm). Written by Robert Elz.
+X
+X     The sdbm library has been around in beta test for quite
+Xa  long  time,  and from whatever little feedback I received
+X(maybe no news is good news), I believe it  has  been  func-
+Xtioning  without  any  significant  problems.  I  would,  of
+Xcourse, appreciate all fixes and/or improvements.  Portabil-
+Xity enhancements would especially be useful.

+X     Hash functions: The algorithm behind  sdbm  implementa-
+Xtion  needs a good bit-scrambling hash function to be effec-
+Xtive. I ran into a set of constants for a simple hash  func-
+Xtion  that  seem  to  help sdbm perform better than ndbm for
+Xvarious inputs:
+X
+X    /*
+X     * polynomial conversion ignoring overflows
+X     * 65599 nice. 65587 even better.
+X     */
+X    long
+X    dbm_hash(char *str, int len) {
+X        register unsigned long n = 0;
+X
+X        while (len--)
+X            n = n * 65599 + *str++;
+X        return n;
+X    }
+X
+X     There may be better hash functions for the purposes  of
+Xdynamic hashing.  Try your favorite, and check the pagefile.
+XIf it contains too many pages with too many holes, (in rela-
+Xtion  to this one for example) or if sdbm simply stops work-
+Xing (fails after SPLTMAX attempts to split)  when  you  feed
+Xyour  NEWS  history  file  to it, you probably do not have a
+Xgood hashing function.  If  you  do  better  (for  different
+Xtypes of input), I would like to know about the function you
+Xuse.
+X
+X     Block sizes: It seems (from  various  tests  on  a  few
+Xmachines)  that a page file block size PBLKSIZ of 1024 is by
+Xfar the best for performance, but this also happens to limit
+Xthe  size  of a key/value pair. Depending on your needs, you
+Xmay wish to increase the page size, and also adjust  PAIRMAX
+X(the maximum size of a key/value pair allowed: should always

+X
+X                           - 5 -
+X
+X
+Xbe at least three words smaller than PBLKSIZ.)  accordingly.
+XThe  system-wide  version  of the library should probably be
+Xconfigured with 1024 (distribution default), as this appears
+Xto be sufficient for most common uses of sdbm.
+X
+XPortability
+X
+X     This package has been tested in many  different  UN*Xes
+Xeven including minix, and appears to be reasonably portable.
+XThis does not mean it will port easily to non-UN*X systems.
+X
+XNotes and Miscellaneous
+X
+X     The sdbm is not a very complicated  package,  at  least
+Xnot  after  you  familiarize yourself with the literature on
+Xexternal hashing. There are other interesting algorithms  in
+Xexistence  that ensure (approximately) single-read access to
+Xa data value associated with any key. These  are  directory-
+Xless schemes such as linear hashing [Lit80] (+ Larson varia-
+Xtions), spiral storage [Mar79] or directory schemes such  as
+Xextensible  hashing  [Fag79] by Fagin et al. I do hope these
+Xsources provide a reasonable playground for  experimentation
+Xwith  other algorithms.  See the June 1988 issue of ACM Com-
+Xputing Surveys [Enb88] for  an  excellent  overview  of  the
+Xfield.

+X.SH NAME
+Xdbe \- Edit a ndbm(3) database
+X.SH USAGE
+Xdbe <database> [-m r|w|rw] [-crtvx] -a|-d|-f|-F|-s [<key> [<content>]]
+X.SH DESCRIPTION
+X\fIdbme\fP operates on ndbm(3) databases.
+XIt can be used to create them, look at them or change them.
+XWhen specifying the value of a key or the content of its associated entry,
+X\\nnn, \\0, \\n, \\t, \\f and \\r are interpreted as usual.
+XWhen displaying key/content pairs, non-printable characters are displayed
+Xusing the \\nnn notation.
+X.SH OPTIONS
+X.IP -a
+XList all entries in the database.
+X.IP -c
+XCreate the database if it does not exist.
+X.IP -d
+XDelete the entry associated with the specified key.
+X.IP -f
+XFetch and display the entry associated with the specified key.
+X.IP -F
+XFetch and display all the entries whose key match the specified
+Xregular-expression
+X.IP "-m r|w|rw"
+XOpen the database in read-only, write-only or read-write mode
+X.IP -r
+XReplace the entry associated with the specified key if it already exists.
+XSee option -s.
+X.IP -s
+XStore an entry under a specific key.
+XAn error occurs if the key already exists and the option -r was not specified.
+X.IP -t
+XRe-initialize the database before executing the command.
+X.IP -v
+XVerbose mode.
+XConfirm stores and deletions.
+X.IP -x
+XIf option -x is used with option -c, then if the database already exists,
+Xan error occurs.
+XThis can be used to implement a simple exclusive access locking mechanism.

+XA The Clone of the \fIndbm\fP library
+X.PP
+XThe sources accompanying this notice \(em \fIsdbm\fP \(em constitute
+Xthe first public release (Dec. 1990) of a complete clone of
+Xthe Berkeley UN*X \fIndbm\fP library. The \fIsdbm\fP library is meant to
+Xclone the proven functionality of \fIndbm\fP as closely as possible,
+Xincluding a few improvements. It is practical, easy to understand, and
+Xcompatible.
+XThe \fIsdbm\fP library is not derived from any licensed, proprietary or
+Xcopyrighted software.
+X.PP
+XThe \fIsdbm\fP implementation is based on a 1978 algorithm
+X[Lar78] by P.-A. (Paul) Larson known as ``Dynamic Hashing''.
+XIn the course of searching for a substitute for \fIndbm\fP, I
+Xprototyped three different external-hashing algorithms [Lar78, Fag79, Lit80]
+Xand ultimately chose Larson's algorithm as a basis of the \fIsdbm\fP
+Ximplementation. The Bell Labs
+X\fIdbm\fP (and therefore \fIndbm\fP) is based on an algorithm invented by
+XKen Thompson, [Tho90, Tor87] and predates Larson's work.
+X.PP
+XThe \fIsdbm\fR programming interface is totally compatible
+Xwith \fIndbm\fP and includes a slight improvement in database initialization.
+XIt is also expected to be binary-compatible under most UN*X versions that
+Xsupport the \fIndbm\fP library.
+X.PP
+XThe \fIsdbm\fP implementation shares the shortcomings of the \fIndbm\fP
+Xlibrary, as a side effect of various simplifications to the original Larson
+Xalgorithm. It does produce \fIholes\fP in the page file as it writes
+Xpages past the end of file. (Larson's paper include a clever solution to
+Xthis problem that is a result of using the hash value directly as a block
+Xaddress.) On the other hand, extensive tests seem to indicate that \fIsdbm\fP
+Xcreates fewer holes in general, and the resulting pagefiles are
+Xsmaller. The \fIsdbm\fP implementation is also faster than \fIndbm\fP
+Xin database creation.
+XUnlike the \fIndbm\fP, the \fIsdbm\fP
+X.CW store
+Xoperation will not ``wander away'' trying to split its
+Xdata pages to insert a datum that \fIcannot\fP (due to elaborate worst-case
+Xsituations) be inserted. (It will fail after a pre-defined number of attempts.)
+X.SH
+XImportant Compatibility Warning
+X.PP
+XThe \fIsdbm\fP and \fIndbm\fP
+Xlibraries \fIcannot\fP share databases: one cannot read the (dir/pag)
+Xdatabase created by the other. This is due to the differences
+Xbetween the \fIndbm\fP and \fIsdbm\fP algorithms\**, 
+X.FS
+XTorek's discussion [Tor87]
+Xindicates that \fIdbm/ndbm\fP implementations use the hash
+Xvalue to traverse the radix trie differently than \fIsdbm\fP
+Xand as a result, the page indexes are generated in \fIdifferent\fP order.
+XFor more information, send e-mail to the author.

+X.CW dbu
+Xis a simple database manipulation program\** that tries to look
+X.FS
+XThe 
+X.CW dbd ,
+X.CW dba ,
+X.CW dbu
+Xutilities are quick hacks and are not fit for production use. They were
+Xdeveloped late one night, just to test out \fIsdbm\fP, and convert some
+Xdatabases.
+X.FE
+Xlike Bell Labs'
+X.CW cbt
+Xutility. It is currently incomplete in functionality.
+XI use
+X.CW dbu
+Xto test out the routines: it takes (from stdin) tab separated
+Xkey/value pairs for commands like
+X.CW build
+Xor
+X.CW insert
+Xor takes keys for
+Xcommands like
+X.CW delete
+Xor
+X.CW look .
+X.P1

+X.P2
+X.PP
+X.CW dba
+Xis a crude analyzer of \fIdbm/sdbm/ndbm\fP
+Xpage files. It scans the entire
+Xpage file, reporting page level statistics, and totals at the end.
+X.PP
+X.CW dbd
+Xis a crude dump program for \fIdbm/ndbm/sdbm\fP
+Xdatabases. It ignores the
+Xbitmap, and dumps the data pages in sequence. It can be used to create
+Xinput for the
+X.CW dbu 
+Xutility.
+XNote that
+X.CW dbd
+Xwill skip any NULLs in the key and data
+Xfields, thus is unsuitable to convert some peculiar databases that
+Xinsist in including the terminating null.
+X.PP
+XI have also included a copy of the
+X.CW dbe
+X(\fIndbm\fP DataBase Editor) by Janick Bergeron [janick@bnr.ca] for
+Xyour pleasure. You may find it more useful than the little
+X.CW dbu
+Xutility.
+X.PP
+X.CW dbm.[ch]
+Xis a \fIdbm\fP library emulation on top of \fIndbm\fP
+X(and hence suitable for \fIsdbm\fP). Written by Robert Elz.
+X.PP
+XThe \fIsdbm\fP
+Xlibrary has been around in beta test for quite a long time, and from whatever
+Xlittle feedback I received (maybe no news is good news), I believe it has been
+Xfunctioning without any significant problems. I would, of course, appreciate
+Xall fixes and/or improvements. Portability enhancements would especially be
+Xuseful.
+X.SH
+XImplementation Issues
+X.PP
+XHash functions:
+XThe algorithm behind \fIsdbm\fP implementation needs a good bit-scrambling
+Xhash function to be effective. I ran into a set of constants for a simple
+Xhash function that seem to help \fIsdbm\fP perform better than \fIndbm\fP
+Xfor various inputs:
+X.P1
+X	/*
+X	 * polynomial conversion ignoring overflows
+X	 * 65599 nice. 65587 even better.
+X	 */
+X	long
+X	dbm_hash(char *str, int len) {
+X		register unsigned long n = 0;
+X	
+X		while (len--)
+X			n = n * 65599 + *str++;
+X		return n;
+X	}
+X.P2
+X.PP
+XThere may be better hash functions for the purposes of dynamic hashing.
+XTry your favorite, and check the pagefile. If it contains too many pages
+Xwith too many holes, (in relation to this one for example) or if
+X\fIsdbm\fP
+Xsimply stops working (fails after 
+X.CW SPLTMAX
+Xattempts to split) when you feed your
+XNEWS 
+X.CW history
+Xfile to it, you probably do not have a good hashing function.
+XIf you do better (for different types of input), I would like to know
+Xabout the function you use.
+X.PP
+XBlock sizes: It seems (from various tests on a few machines) that a page
+Xfile block size
+X.CW PBLKSIZ
+Xof 1024 is by far the best for performance, but
+Xthis also happens to limit the size of a key/value pair. Depending on your
+Xneeds, you may wish to increase the page size, and also adjust
+X.CW PAIRMAX
+X(the maximum size of a key/value pair allowed: should always be at least
+Xthree words smaller than
+X.CW PBLKSIZ .)
+Xaccordingly. The system-wide version of the library
+Xshould probably be
+Xconfigured with 1024 (distribution default), as this appears to be sufficient
+Xfor most common uses of \fIsdbm\fP.
+X.SH
+XPortability
+X.PP
+XThis package has been tested in many different UN*Xes even including minix,
+Xand appears to be reasonably portable. This does not mean it will port
+Xeasily to non-UN*X systems.
+X.SH
+XNotes and Miscellaneous
+X.PP
+XThe \fIsdbm\fP is not a very complicated package, at least not after you
+Xfamiliarize yourself with the literature on external hashing. There are
+Xother interesting algorithms in existence that ensure (approximately)
+Xsingle-read access to a data value associated with any key. These are
+Xdirectory-less schemes such as \fIlinear hashing\fP [Lit80] (+ Larson
+Xvariations), \fIspiral storage\fP [Mar79] or directory schemes such as
+X\fIextensible hashing\fP [Fag79] by Fagin et al. I do hope these sources
+Xprovide a reasonable playground for experimentation with other algorithms.
+XSee the June 1988 issue of ACM Computing Surveys [Enb88] for an
+Xexcellent overview of the field.

+X.LP
+XThis package allows an application to maintain a mapping of <key,value> pairs
+Xin disk files.  This is not to be considered a real database system, but is
+Xstill useful in many simple applications built around fast retrieval of a data
+Xvalue from a key.  This implementation uses an external hashing scheme,
+Xcalled Dynamic Hashing, as described by Per-Aake Larson in BIT 18 (1978) pp.
+X184-201.  Retrieval of any item usually requires a single disk access.
+XThe application interface is compatible with the
+X.IR ndbm (3)
+Xlibrary.
+X.LP
+XAn
+X.B sdbm
+Xdatabase is kept in two files usually given the extensions
+X.B \.dir
+Xand
+X.BR \.pag .
+XThe
+X.B \.dir
+Xfile contains a bitmap representing a forest of binary hash trees, the leaves
+Xof which indicate data pages in the
+X.B \.pag
+Xfile.
+X.LP
+XThe application interface uses the
+X.B datum
+Xstructure to describe both
+X.I keys
+Xand
+X.IR value s.
+XA
+X.B datum
+Xspecifies a byte sequence of
+X.I dsize
+Xsize pointed to by
+X.IR dptr .
+XIf you use
+X.SM ASCII
+Xstrings as
+X.IR key s
+Xor
+X.IR value s,
+Xthen you must decide whether or not to include the terminating
+X.SM NUL
+Xbyte which sometimes defines strings.  Including it will require larger
+Xdatabase files, but it will be possible to get sensible output from a
+X.IR strings (1)
+Xcommand applied to the data file.
+X.LP
+XIn order to allow a process using this package to manipulate multiple
+Xdatabases, the applications interface always requires a
+X.IR handle ,
+Xa
+X.BR "DBM *" ,
+Xto identify the database to be manipulated.  Such a handle can be obtained
+Xfrom the only routines that do not require it, namely
+X.BR dbm_open (\|)
+Xor
+X.BR dbm_prep (\|).
+XEither of these will open or create the two necessary files.  The
+Xdifference is that the latter allows explicitly naming the bitmap and data
+Xfiles whereas
+X.BR dbm_open (\|)
+Xwill take a base file name and call
+X.BR dbm_prep (\|)
+Xwith the default extensions.
+XThe
+X.I flags
+Xand
+X.I mode
+Xparameters are the same as for
+X.BR open (2).
+X.LP
+XTo free the resources occupied while a database handle is active, call
+X.BR dbm_close (\|).
+X.LP
+XGiven a handle, one can retrieve data associated with a key by using the
+X.BR dbm_fetch (\|)
+Xroutine, and associate data with a key by using the
+X.BR dbm_store (\|)
+Xroutine.
+X.LP
+XThe values of the
+X.I flags
+Xparameter for
+X.BR dbm_store (\|)
+Xcan be either
+X.BR \s-1DBM_INSERT\s0 ,
+Xwhich will not change an existing entry with the same key, or
+X.BR \s-1DBM_REPLACE\s0 ,
+Xwhich will replace an existing entry with the same key.
+XKeys are unique within the database.
+X.LP
+XTo delete a key and its associated value use the
+X.BR dbm_delete (\|)
+Xroutine.
+X.LP
+XTo retrieve every key in the database, use a loop like:
+X.sp
+X.nf
+X.ft B
+Xfor (key = dbm_firstkey(db); key.dptr != NULL; key = dbm_nextkey(db))
+X        ;
+X.ft R
+X.fi
+X.LP
+XThe order of retrieval is unspecified.
+X.LP
+XIf you determine that the performance of the database is inadequate or
+Xyou notice clustering or other effects that may be due to the hashing
+Xalgorithm used by this package, you can override it by supplying your
+Xown
+X.BR dbm_hash (\|)
+Xroutine.  Doing so will make the database unintelligable to any other
+Xapplications that do not use your specialized hash function.
+X.sp
+X.LP
+XThe following macros are defined in the header file:
+X.IP
+X.BR dbm_rdonly (\|)
+Xreturns true if the database has been opened read\-only.
+X.IP
+X.BR dbm_error (\|)
+Xreturns true if an I/O error has occurred.
+X.IP
+X.BR dbm_clearerr (\|)
+Xallows you to clear the error flag if you think you know what the error
+Xwas and insist on ignoring it.
+X.IP
+X.BR dbm_dirfno (\|)
+Xreturns the file descriptor associated with the bitmap file.
+X.IP
+X.BR dbm_pagfno (\|)
+Xreturns the file descriptor associated with the data file.
+X.SH SEE ALSO
+X.IR open (2).
+X.SH DIAGNOSTICS
+XFunctions that return a
+X.B "DBM *"
+Xhandle will use
+X.SM NULL
+Xto indicate an error.
+XFunctions that return an
+X.B int
+Xwill use \-1 to indicate an error.  The normal return value in that case is 0.
+XFunctions that return a
+X.B datum
+Xwill return
+X.B nullitem
+Xto indicate an error.
+X.LP
+XAs a special case of
+X.BR dbm_store (\|),
+Xif it is called with the
+X.B \s-1DBM_INSERT\s0
+Xflag and the key already exists in the database, the return value will be 1.
+X.LP
+XIn general, if a function parameter is invalid,
+X.B errno
+Xwill be set to
+X.BR \s-1EINVAL\s0 .
+XIf a write operation is requested on a read-only database,
+X.B errno
+Xwill be set to
+X.BR \s-1ENOPERM\s0 .
+XIf a memory allocation (using
+X.IR malloc (3))
+Xfailed,
+X.B errno
+Xwill be set to
+X.BR \s-1ENOMEM\s0 .
+XFor I/O operation failures
+X.B errno
+Xwill contain the value set by the relevant failed system call, either
+X.IR read (2),
+X.IR write (2),
+Xor
+X.IR lseek (2).
+X.SH AUTHOR
+X.IP "Ozan S. Yigit" (oz@nexus.yorku.ca)
+X.SH BUGS
+XThe sum of key and value data sizes must not exceed
+X.B \s-1PAIRMAX\s0
+X(1008 bytes).
+X.LP
+XThe sum of the key and value data sizes where several keys hash to the
+Xsame value must fit within one bitmap page.
+X.LP
+XThe
+X.B \.pag
+Xfile will contain holes, so its apparent size is larger than its contents.
+XWhen copied through the filesystem the holes will be filled.
+X.LP
+XThe contents of
+X.B datum
+Xvalues returned are in volatile storage.  If you want to retain the values
+Xpointed to, you must copy them immediately before another call to this package.
+X.LP
+XThe only safe way for multiple processes to (read and) update a database at
+Xthe same time, is to implement a private locking scheme outside this package
+Xand open and close the database between lock acquisitions.  It is safe for
+Xmultiple processes to concurrently access a database read-only.
+X.SH APPLICATIONS PORTABILITY
+XFor complete source code compatibility with the Berkeley Unix
+X.IR ndbm (3)
+Xlibrary, the 
+X.B sdbm.h
+Xheader file should be installed in
+X.BR /usr/include/ndbm.h .

+Changes from the earlier BETA releases.
+
+o dbm_prep does everything now, so dbm_open is just a simple
+  wrapper that builds the default filenames. dbm_prep no longer
+  requires a (DBM *) db parameter: it allocates one itself. It
+  returns (DBM *) db or (DBM *) NULL.
+
+o makroom is now reliable. In the common-case optimization of the page
+  split, the page into which the incoming key/value pair is to be inserted
+  is write-deferred (if the split is successful), thereby saving a cosly
+  write.  BUT, if the split does not make enough room (unsuccessful), the
+  deferred page is written out, as the failure-window is now dependent on
+  the number of split attempts.
+
+o if -DDUFF is defined, hash function will also use the DUFF construct.
+  This may look like a micro-performance tweak (maybe it is), but in fact,
+  the hash function is the third most-heavily used function, after read
+  and write.

+
+
+Implementation is the sincerest form of flattery. - L. Peter
+Deutsch
+
+A The Clone of the ndbm library
+
+     The sources accompanying this notice - sdbm  -  consti-
+tute  the  first  public  release  (Dec. 1990) of a complete
+clone of the Berkeley UN*X ndbm library. The sdbm library is
+meant  to  clone the proven functionality of ndbm as closely
+as possible, including a few improvements. It is  practical,
+easy to understand, and compatible.  The sdbm library is not
+derived  from  any  licensed,  proprietary  or   copyrighted
+software.
+
+     The sdbm implementation is based on  a  1978  algorithm
+[Lar78] by P.-A. (Paul) Larson known as ``Dynamic Hashing''.
+In the course of searching for a substitute for ndbm, I pro-
+totyped  three different external-hashing algorithms [Lar78,
+Fag79, Lit80] and ultimately chose Larson's algorithm  as  a
+basis  of  the  sdbm  implementation. The Bell Labs dbm (and
+therefore ndbm) is based on an  algorithm  invented  by  Ken
+Thompson, [Tho90, Tor87] and predates Larson's work.
+
+     The sdbm programming interface  is  totally  compatible
+with ndbm and includes a slight improvement in database ini-
+tialization.  It is also expected  to  be  binary-compatible
+under most UN*X versions that support the ndbm library.
+
+     The sdbm implementation shares the shortcomings of  the
+ndbm library, as a side effect of various simplifications to
+the original Larson algorithm. It does produce holes in  the
+page file as it writes pages past the end of file. (Larson's
+paper include a clever solution to this problem  that  is  a
+result of using the hash value directly as a block address.)
+On the other hand, extensive tests  seem  to  indicate  that
+sdbm creates fewer holes in general, and the resulting page-
+files are smaller. The sdbm implementation  is  also  faster
+than  ndbm  in database creation.  Unlike the ndbm, the sdbm

+
+store operation will not ``wander away'' trying to split its
+data  pages  to insert a datum that cannot (due to elaborate
+worst-case situations) be inserted. (It will  fail  after  a
+pre-defined number of attempts.)
+
+Important Compatibility Warning
+
+     The sdbm and ndbm libraries cannot share databases: one
+cannot  read  the  (dir/pag)  database created by the other.
+This is due to the differences between  the  ndbm  and  sdbm
+algorithms[2], and the hash functions used.  It is  easy  to
+convert  between the dbm/ndbm databases and sdbm by ignoring
+the index completely: see dbd, dbu etc.

+_________________________
+
+  [2] Torek's   discussion   [Tor87]   indicates   that
+dbm/ndbm implementations use the hash value to traverse
+the radix trie differently than sdbm and as  a  result,
+the page indexes are generated in different order.  For

+
+     dbu is a simple database manipulation  program[4]  that
+tries to look like Bell Labs' cbt utility. It  is  currently
+incomplete in functionality.  I use dbu to test out the rou-
+tines: it takes (from stdin) tab separated  key/value  pairs
+for commands like build or insert or takes keys for commands
+like delete or look.
+
+    dbu <build|creat|look|insert|cat|delete> dbmfile
+
+     dba is a crude analyzer of dbm/sdbm/ndbm page files. It
+scans the entire page file, reporting page level statistics,
+and totals at the end.
+
+     dbd is a crude dump  program  for  dbm/ndbm/sdbm  data-
+bases.  It  ignores  the bitmap, and dumps the data pages in
+sequence. It can be used to create input for the  dbu  util-
+ity.   Note that dbd will skip any NULLs in the key and data
+fields,  thus  is  unsuitable  to  convert   some   peculiar
+_________________________
+
+  [4] The dbd, dba, dbu utilities are quick  hacks  and
+are  not  fit  for  production use. They were developed
+late one night, just to test out sdbm, and convert some
+databases.

+                           - 4 -

+
+databases that insist in including the terminating null.
+
+     I have also included a copy of the dbe  (ndbm  DataBase
+Editor)  by  Janick Bergeron [janick@bnr.ca] for your pleas-
+ure. You may find it more useful than the little  dbu  util-
+ity.
+
+     dbm.[ch] is a dbm library emulation on top of ndbm (and
+hence suitable for sdbm). Written by Robert Elz.
+
+     The sdbm library has been around in beta test for quite
+a  long  time,  and from whatever little feedback I received
+(maybe no news is good news), I believe it  has  been  func-
+tioning  without  any  significant  problems.  I  would,  of
+course, appreciate all fixes and/or improvements.  Portabil-
+ity enhancements would especially be useful.
+
+Implementation Issues
+
+     Hash functions: The algorithm behind  sdbm  implementa-
+tion  needs a good bit-scrambling hash function to be effec-
+tive. I ran into a set of constants for a simple hash  func-
+tion  that  seem  to  help sdbm perform better than ndbm for
+various inputs:
+
+    /*
+     * polynomial conversion ignoring overflows
+     * 65599 nice. 65587 even better.
+     */
+    long
+    dbm_hash(char *str, int len) {
+        register unsigned long n = 0;
+
+        while (len--)
+            n = n * 65599 + *str++;
+        return n;
+    }
+
+     There may be better hash functions for the purposes  of
+dynamic hashing.  Try your favorite, and check the pagefile.
+If it contains too many pages with too many holes, (in rela-
+tion  to this one for example) or if sdbm simply stops work-
+ing (fails after SPLTMAX attempts to split)  when  you  feed
+your  NEWS  history  file  to it, you probably do not have a
+good hashing function.  If  you  do  better  (for  different
+types of input), I would like to know about the function you
+use.
+
+     Block sizes: It seems (from  various  tests  on  a  few
+machines)  that a page file block size PBLKSIZ of 1024 is by
+far the best for performance, but this also happens to limit
+the  size  of a key/value pair. Depending on your needs, you
+may wish to increase the page size, and also adjust  PAIRMAX
+(the maximum size of a key/value pair allowed: should always
+
+
+
+
+
+
+
+
+
+                           - 5 -
+
+
+be at least three words smaller than PBLKSIZ.)  accordingly.
+The  system-wide  version  of the library should probably be
+configured with 1024 (distribution default), as this appears
+to be sufficient for most common uses of sdbm.
+
+Portability
+
+     This package has been tested in many  different  UN*Xes
+even including minix, and appears to be reasonably portable.
+This does not mean it will port easily to non-UN*X systems.
+
+Notes and Miscellaneous
+
+     The sdbm is not a very complicated  package,  at  least
+not  after  you  familiarize yourself with the literature on
+external hashing. There are other interesting algorithms  in
+existence  that ensure (approximately) single-read access to
+a data value associated with any key. These  are  directory-
+less schemes such as linear hashing [Lit80] (+ Larson varia-
+tions), spiral storage [Mar79] or directory schemes such  as
+extensible  hashing  [Fag79] by Fagin et al. I do hope these
+sources provide a reasonable playground for  experimentation
+with  other algorithms.  See the June 1988 issue of ACM Com-
+puting Surveys [Enb88] for  an  excellent  overview  of  the
+field.

+.SH NAME
+dbe \- Edit a ndbm(3) database
+.SH USAGE
+dbe <database> [-m r|w|rw] [-crtvx] -a|-d|-f|-F|-s [<key> [<content>]]
+.SH DESCRIPTION
+\fIdbme\fP operates on ndbm(3) databases.
+It can be used to create them, look at them or change them.
+When specifying the value of a key or the content of its associated entry,
+\\nnn, \\0, \\n, \\t, \\f and \\r are interpreted as usual.
+When displaying key/content pairs, non-printable characters are displayed
+using the \\nnn notation.
+.SH OPTIONS
+.IP -a
+List all entries in the database.
+.IP -c
+Create the database if it does not exist.
+.IP -d
+Delete the entry associated with the specified key.
+.IP -f
+Fetch and display the entry associated with the specified key.
+.IP -F
+Fetch and display all the entries whose key match the specified
+regular-expression
+.IP "-m r|w|rw"
+Open the database in read-only, write-only or read-write mode
+.IP -r
+Replace the entry associated with the specified key if it already exists.
+See option -s.
+.IP -s
+Store an entry under a specific key.
+An error occurs if the key already exists and the option -r was not specified.
+.IP -t
+Re-initialize the database before executing the command.
+.IP -v
+Verbose mode.
+Confirm stores and deletions.
+.IP -x
+If option -x is used with option -c, then if the database already exists,
+an error occurs.
+This can be used to implement a simple exclusive access locking mechanism.

+A The Clone of the \fIndbm\fP library
+.PP
+The sources accompanying this notice \(em \fIsdbm\fP \(em constitute
+the first public release (Dec. 1990) of a complete clone of
+the Berkeley UN*X \fIndbm\fP library. The \fIsdbm\fP library is meant to
+clone the proven functionality of \fIndbm\fP as closely as possible,
+including a few improvements. It is practical, easy to understand, and
+compatible.
+The \fIsdbm\fP library is not derived from any licensed, proprietary or
+copyrighted software.
+.PP
+The \fIsdbm\fP implementation is based on a 1978 algorithm
+[Lar78] by P.-A. (Paul) Larson known as ``Dynamic Hashing''.
+In the course of searching for a substitute for \fIndbm\fP, I
+prototyped three different external-hashing algorithms [Lar78, Fag79, Lit80]
+and ultimately chose Larson's algorithm as a basis of the \fIsdbm\fP
+implementation. The Bell Labs
+\fIdbm\fP (and therefore \fIndbm\fP) is based on an algorithm invented by
+Ken Thompson, [Tho90, Tor87] and predates Larson's work.
+.PP
+The \fIsdbm\fR programming interface is totally compatible
+with \fIndbm\fP and includes a slight improvement in database initialization.
+It is also expected to be binary-compatible under most UN*X versions that
+support the \fIndbm\fP library.
+.PP
+The \fIsdbm\fP implementation shares the shortcomings of the \fIndbm\fP
+library, as a side effect of various simplifications to the original Larson
+algorithm. It does produce \fIholes\fP in the page file as it writes
+pages past the end of file. (Larson's paper include a clever solution to
+this problem that is a result of using the hash value directly as a block
+address.) On the other hand, extensive tests seem to indicate that \fIsdbm\fP
+creates fewer holes in general, and the resulting pagefiles are
+smaller. The \fIsdbm\fP implementation is also faster than \fIndbm\fP
+in database creation.
+Unlike the \fIndbm\fP, the \fIsdbm\fP
+.CW store
+operation will not ``wander away'' trying to split its
+data pages to insert a datum that \fIcannot\fP (due to elaborate worst-case
+situations) be inserted. (It will fail after a pre-defined number of attempts.)
+.SH
+Important Compatibility Warning
+.PP
+The \fIsdbm\fP and \fIndbm\fP
+libraries \fIcannot\fP share databases: one cannot read the (dir/pag)
+database created by the other. This is due to the differences
+between the \fIndbm\fP and \fIsdbm\fP algorithms\**, 
+.FS
+Torek's discussion [Tor87]
+indicates that \fIdbm/ndbm\fP implementations use the hash
+value to traverse the radix trie differently than \fIsdbm\fP
+and as a result, the page indexes are generated in \fIdifferent\fP order.
+For more information, send e-mail to the author.
+.FE
+and the hash functions
+used.
+It is easy to convert between the \fIdbm/ndbm\fP databases and \fIsdbm\fP
+by ignoring the index completely: see
+.CW dbd ,
+.CW dbu
+etc.

+.CW dbu
+is a simple database manipulation program\** that tries to look
+.FS
+The 
+.CW dbd ,
+.CW dba ,
+.CW dbu
+utilities are quick hacks and are not fit for production use. They were
+developed late one night, just to test out \fIsdbm\fP, and convert some
+databases.
+.FE
+like Bell Labs'
+.CW cbt
+utility. It is currently incomplete in functionality.
+I use
+.CW dbu
+to test out the routines: it takes (from stdin) tab separated
+key/value pairs for commands like
+.CW build
+or
+.CW insert
+or takes keys for
+commands like
+.CW delete
+or
+.CW look .
+.P1
+	dbu <build|creat|look|insert|cat|delete> dbmfile
+.P2
+.PP
+.CW dba
+is a crude analyzer of \fIdbm/sdbm/ndbm\fP
+page files. It scans the entire
+page file, reporting page level statistics, and totals at the end.
+.PP
+.CW dbd
+is a crude dump program for \fIdbm/ndbm/sdbm\fP
+databases. It ignores the
+bitmap, and dumps the data pages in sequence. It can be used to create
+input for the
+.CW dbu 
+utility.
+Note that
+.CW dbd
+will skip any NULLs in the key and data
+fields, thus is unsuitable to convert some peculiar databases that
+insist in including the terminating null.
+.PP
+I have also included a copy of the
+.CW dbe
+(\fIndbm\fP DataBase Editor) by Janick Bergeron [janick@bnr.ca] for
+your pleasure. You may find it more useful than the little
+.CW dbu
+utility.
+.PP
+.CW dbm.[ch]
+is a \fIdbm\fP library emulation on top of \fIndbm\fP
+(and hence suitable for \fIsdbm\fP). Written by Robert Elz.
+.PP
+The \fIsdbm\fP
+library has been around in beta test for quite a long time, and from whatever
+little feedback I received (maybe no news is good news), I believe it has been
+functioning without any significant problems. I would, of course, appreciate
+all fixes and/or improvements. Portability enhancements would especially be
+useful.
+.SH
+Implementation Issues
+.PP
+Hash functions:
+The algorithm behind \fIsdbm\fP implementation needs a good bit-scrambling
+hash function to be effective. I ran into a set of constants for a simple
+hash function that seem to help \fIsdbm\fP perform better than \fIndbm\fP
+for various inputs:
+.P1
+	/*
+	 * polynomial conversion ignoring overflows
+	 * 65599 nice. 65587 even better.
+	 */
+	long
+	dbm_hash(char *str, int len) {
+		register unsigned long n = 0;
+	
+		while (len--)
+			n = n * 65599 + *str++;
+		return n;
+	}
+.P2
+.PP
+There may be better hash functions for the purposes of dynamic hashing.
+Try your favorite, and check the pagefile. If it contains too many pages
+with too many holes, (in relation to this one for example) or if
+\fIsdbm\fP
+simply stops working (fails after 
+.CW SPLTMAX
+attempts to split) when you feed your
+NEWS 
+.CW history
+file to it, you probably do not have a good hashing function.
+If you do better (for different types of input), I would like to know
+about the function you use.
+.PP
+Block sizes: It seems (from various tests on a few machines) that a page
+file block size
+.CW PBLKSIZ
+of 1024 is by far the best for performance, but
+this also happens to limit the size of a key/value pair. Depending on your
+needs, you may wish to increase the page size, and also adjust
+.CW PAIRMAX
+(the maximum size of a key/value pair allowed: should always be at least
+three words smaller than
+.CW PBLKSIZ .)
+accordingly. The system-wide version of the library
+should probably be
+configured with 1024 (distribution default), as this appears to be sufficient
+for most common uses of \fIsdbm\fP.
+.SH
+Portability
+.PP
+This package has been tested in many different UN*Xes even including minix,
+and appears to be reasonably portable. This does not mean it will port
+easily to non-UN*X systems.
+.SH
+Notes and Miscellaneous
+.PP
+The \fIsdbm\fP is not a very complicated package, at least not after you
+familiarize yourself with the literature on external hashing. There are
+other interesting algorithms in existence that ensure (approximately)
+single-read access to a data value associated with any key. These are
+directory-less schemes such as \fIlinear hashing\fP [Lit80] (+ Larson
+variations), \fIspiral storage\fP [Mar79] or directory schemes such as
+\fIextensible hashing\fP [Fag79] by Fagin et al. I do hope these sources
+provide a reasonable playground for experimentation with other algorithms.
+See the June 1988 issue of ACM Computing Surveys [Enb88] for an
+excellent overview of the field.

+.LP
+This package allows an application to maintain a mapping of <key,value> pairs
+in disk files.  This is not to be considered a real database system, but is
+still useful in many simple applications built around fast retrieval of a data
+value from a key.  This implementation uses an external hashing scheme,
+called Dynamic Hashing, as described by Per-Aake Larson in BIT 18 (1978) pp.
+184-201.  Retrieval of any item usually requires a single disk access.
+The application interface is compatible with the
+.IR ndbm (3)
+library.
+.LP
+An
+.B sdbm
+database is kept in two files usually given the extensions
+.B \.dir
+and
+.BR \.pag .
+The
+.B \.dir
+file contains a bitmap representing a forest of binary hash trees, the leaves
+of which indicate data pages in the
+.B \.pag
+file.
+.LP
+The application interface uses the
+.B datum
+structure to describe both
+.I keys
+and
+.IR value s.
+A
+.B datum
+specifies a byte sequence of
+.I dsize
+size pointed to by
+.IR dptr .
+If you use
+.SM ASCII
+strings as
+.IR key s
+or
+.IR value s,
+then you must decide whether or not to include the terminating
+.SM NUL
+byte which sometimes defines strings.  Including it will require larger
+database files, but it will be possible to get sensible output from a
+.IR strings (1)
+command applied to the data file.
+.LP
+In order to allow a process using this package to manipulate multiple
+databases, the applications interface always requires a
+.IR handle ,
+a
+.BR "DBM *" ,
+to identify the database to be manipulated.  Such a handle can be obtained
+from the only routines that do not require it, namely
+.BR dbm_open (\|)
+or
+.BR dbm_prep (\|).
+Either of these will open or create the two necessary files.  The
+difference is that the latter allows explicitly naming the bitmap and data
+files whereas
+.BR dbm_open (\|)
+will take a base file name and call
+.BR dbm_prep (\|)
+with the default extensions.
+The
+.I flags
+and
+.I mode
+parameters are the same as for
+.BR open (2).
+.LP
+To free the resources occupied while a database handle is active, call
+.BR dbm_close (\|).
+.LP
+Given a handle, one can retrieve data associated with a key by using the
+.BR dbm_fetch (\|)
+routine, and associate data with a key by using the
+.BR dbm_store (\|)
+routine.
+.LP
+The values of the
+.I flags
+parameter for
+.BR dbm_store (\|)
+can be either
+.BR \s-1DBM_INSERT\s0 ,
+which will not change an existing entry with the same key, or
+.BR \s-1DBM_REPLACE\s0 ,
+which will replace an existing entry with the same key.
+Keys are unique within the database.
+.LP
+To delete a key and its associated value use the
+.BR dbm_delete (\|)
+routine.
+.LP
+To retrieve every key in the database, use a loop like:
+.sp
+.nf
+.ft B
+for (key = dbm_firstkey(db); key.dptr != NULL; key = dbm_nextkey(db))
+        ;
+.ft R
+.fi
+.LP
+The order of retrieval is unspecified.
+.LP
+If you determine that the performance of the database is inadequate or
+you notice clustering or other effects that may be due to the hashing
+algorithm used by this package, you can override it by supplying your
+own
+.BR dbm_hash (\|)
+routine.  Doing so will make the database unintelligable to any other
+applications that do not use your specialized hash function.
+.sp
+.LP
+The following macros are defined in the header file:
+.IP
+.BR dbm_rdonly (\|)
+returns true if the database has been opened read\-only.
+.IP
+.BR dbm_error (\|)
+returns true if an I/O error has occurred.
+.IP
+.BR dbm_clearerr (\|)
+allows you to clear the error flag if you think you know what the error
+was and insist on ignoring it.
+.IP
+.BR dbm_dirfno (\|)
+returns the file descriptor associated with the bitmap file.
+.IP
+.BR dbm_pagfno (\|)
+returns the file descriptor associated with the data file.
+.SH SEE ALSO
+.IR open (2).
+.SH DIAGNOSTICS
+Functions that return a
+.B "DBM *"
+handle will use
+.SM NULL
+to indicate an error.
+Functions that return an
+.B int
+will use \-1 to indicate an error.  The normal return value in that case is 0.
+Functions that return a
+.B datum
+will return
+.B nullitem
+to indicate an error.
+.LP
+As a special case of
+.BR dbm_store (\|),
+if it is called with the
+.B \s-1DBM_INSERT\s0
+flag and the key already exists in the database, the return value will be 1.
+.LP
+In general, if a function parameter is invalid,
+.B errno
+will be set to
+.BR \s-1EINVAL\s0 .
+If a write operation is requested on a read-only database,
+.B errno
+will be set to
+.BR \s-1ENOPERM\s0 .
+If a memory allocation (using
+.IR malloc (3))
+failed,
+.B errno
+will be set to
+.BR \s-1ENOMEM\s0 .
+For I/O operation failures
+.B errno
+will contain the value set by the relevant failed system call, either
+.IR read (2),
+.IR write (2),
+or
+.IR lseek (2).
+.SH AUTHOR
+.IP "Ozan S. Yigit" (oz@nexus.yorku.ca)
+.SH BUGS
+The sum of key and value data sizes must not exceed
+.B \s-1PAIRMAX\s0
+(1008 bytes).
+.LP
+The sum of the key and value data sizes where several keys hash to the
+same value must fit within one bitmap page.
+.LP
+The
+.B \.pag
+file will contain holes, so its apparent size is larger than its contents.
+When copied through the filesystem the holes will be filled.
+.LP
+The contents of
+.B datum
+values returned are in volatile storage.  If you want to retain the values
+pointed to, you must copy them immediately before another call to this package.
+.LP
+The only safe way for multiple processes to (read and) update a database at
+the same time, is to implement a private locking scheme outside this package
+and open and close the database between lock acquisitions.  It is safe for
+multiple processes to concurrently access a database read-only.
+.SH APPLICATIONS PORTABILITY
+For complete source code compatibility with the Berkeley Unix
+.IR ndbm (3)
+library, the 
+.B sdbm.h
+header file should be installed in
+.BR /usr/include/ndbm.h .
+.LP
+The
+.B nullitem
+data item, and the
+.BR dbm_prep (\|),
+.BR dbm_hash (\|),
+.BR dbm_rdonly (\|),
+.BR dbm_dirfno (\|),
+and
+.BR dbm_pagfno (\|)
+functions are unique to this package.
