There are a number +of porting directories, for various architecture/OS combinations. Pick +the one that's closest to yours and try "make".

Read through the Makefile and compat.h and make whatever +changes are appropriate to your system. If there's an architecture +that's close to yours, you probably should diff the Makefile and +compat.h in that tree against the standard ones and see what changes +were necessary, as they're probably necessary for you as well. Then, +enter "make" and see what happens! + +There are several subroutines that are found in POSIX 1003.2, ANSI +C, or 4.4BSD that you may not have. Once you get libdb.a to compile, +go through the list of undefined routines and add entries to the MISC +line in the Makefile as necessary. + +If you have to add some functions that are missing (and which aren't +in the PORT/clib directory), please don't add them in the PORT/clib +directory. Add them in a MACH/local directory, and add lines of the +form: + + function.o: local/function.o + ${CL} -Ilocal local/function.o + +to your local Makefile. + +Hopefully, over time, we'll develop a set of system directories that +are known to work. If you send me the changes that were necessary to +make your system work, this will happen much more quickly. + +In some of the system directories, you'll see a file named OTHER_PATCHES. +This is a set of patches which you'll have to make from the top-level db +directory to get libdb.a to run on this system: + + cd .. + patch < PORT/MACH/OTHER_PATCHES + +If patch prompts you for the name of the file to modify (some versions +of patch don't figure it out on their own) use the file name which patch +displays. + +Some knobs you may have to turn: + +In include/db.h: + Before attempting to build libdb, you should look through the + db.h file, and adjust it as necessary for your system. The + only adjustments that you should need to make are for the + fixed sized typedef's at the top of the file. Make sure they're + right for your system. + +In include/compat.h: + Before attempting to build libdb, you should look through the + compat.h file, and adjust it as necessary for your system. + It's possible to use the #ifndef construct to figure out if a + #ifdef has been set, but C provides no similar method to figure + out if a typedef has been done. Your compile errors should + give you a good indication of which ones you need. + +You may see warning messages about illegal pointer combinations. You may +also see lots of warning messages about #define's being redefined. These +can mostly be ignored. I usually ignore warning messages until something +doesn't work. Some systems produce thousands of lines of useless warnings, +bless their little hearts. + +The other parts of the PORT directory are as follows: + + The directory PORT/clib is a set of functions that the 4.4BSD + C library had and which your system may not have. They are + added to the MISC line of the Makefile if they aren't defined + when you try and load libdb.a. + + The directory PORT/include is header files that the 4.4BSD + system had which your system may not have. There is also + one really important extra one, named compat.h, which is a + set of compatibility work-arounds that you'll almost certainly + have to copy and modify for a new system. + + The symbolic link PORT/sys points to the PORT/include directory + so that includes of the form work. + +Some of the more common portability problems: + + If you don't have: + + memmove(3): add memmove.o + mkstemp(3): add mktemp.o + + ... to the MISC line in the Makefile. + + If you don't have snprintf/vsnprintf(3), add snprintf.o to the + MISC line in the Makefile. This workaround depends on your + system having vsprintf(3) -- if you don't, there's no workaround + other than changing the source code to not use the snprintf calls. + If you have to make that change, check to see if your vsprintf + returns a length or a char *; if it's the latter, make sure you + set VSPRINTF_CHARSTAR in the MACH/include/compat.h file. + +Installing the DB library: + + The Makefile builds a C library named libdb.a. This file needs + to be installed in a place where the loader will automatically + look for it (or, if you're building it for a single project, + wherever that project's Makefile loads it from). + + In addition, the header file PORT/include/db.h must be copied to + a directory (often /usr/include/) where programs that use the + db package can include it in their source. (If you intend to use + the ndbm interface to libdb, you'll need to copy the header file + PORT/include/ndbm.h as well.) diff --git a/db.1.85/PORT/aix.3.2/Makefile b/db.1.85/PORT/aix.3.2/Makefile new file mode 100644 index 0000000..85b09a7 --- /dev/null +++ b/db.1.85/PORT/aix.3.2/Makefile @@ -0,0 +1,102 @@ +# @(#)Makefile 8.9 (Berkeley) 7/14/94 + +LIBDB= libdb.a +OBJ1= hash.o hash_bigkey.o hash_buf.o hash_func.o hash_log2.o hash_page.o \ + hsearch.o ndbm.o +OBJ2= bt_close.o bt_conv.o bt_debug.o bt_delete.o bt_get.o bt_open.o \ + bt_overflow.o bt_page.o bt_put.o bt_search.o bt_seq.o bt_split.o \ + bt_utils.o +OBJ3= db.o +OBJ4= mpool.o +OBJ5= rec_close.o rec_delete.o rec_get.o rec_open.o rec_put.o rec_search.o \ + rec_seq.o rec_utils.o + +MISC= snprintf.o + +${LIBDB}: ${OBJ1} ${OBJ2} ${OBJ3} ${OBJ4} ${OBJ5} ${MISC} + rm -f $@ + ar cq $@ \ + `lorder ${OBJ1} ${OBJ2} ${OBJ3} ${OBJ4} ${OBJ5} ${MISC} | tsort` + ranlib $@ + +clean: + rm -f ${LIBDB} ${OBJ1} ${OBJ2} ${OBJ3} ${OBJ4} ${OBJ5} ${MISC} + +OORG= -O +CL= ${CC} -c -D__DBINTERFACE_PRIVATE ${OORG} -I. -Iinclude + +hash.o: ../../hash/hash.c + ${CL} -I../../hash ../../hash/hash.c +hash_bigkey.o: ../../hash/hash_bigkey.c + ${CL} -I../../hash ../../hash/hash_bigkey.c +hash_buf.o: ../../hash/hash_buf.c + ${CL} -I../../hash ../../hash/hash_buf.c +hash_func.o: ../../hash/hash_func.c + ${CL} -I../../hash ../../hash/hash_func.c +hash_log2.o: ../../hash/hash_log2.c + ${CL} -I../../hash ../../hash/hash_log2.c +hash_page.o: ../../hash/hash_page.c + ${CL} -I../../hash ../../hash/hash_page.c +hsearch.o: ../../hash/hsearch.c + ${CL} -I../../hash ../../hash/hsearch.c +ndbm.o: ../../hash/ndbm.c + ${CL} -I../../hash ../../hash/ndbm.c + +bt_close.o: ../../btree/bt_close.c + ${CL} -I../../btree ../../btree/bt_close.c +bt_conv.o: ../../btree/bt_conv.c + ${CL} -I../../btree ../../btree/bt_conv.c +bt_debug.o: ../../btree/bt_debug.c + ${CL} -I../../btree ../../btree/bt_debug.c +bt_delete.o: ../../btree/bt_delete.c + ${CL} -I../../btree ../../btree/bt_delete.c +bt_get.o: ../../btree/bt_get.c + ${CL} -I../../btree ../../btree/bt_get.c +bt_open.o: ../../btree/bt_open.c + ${CL} -I../../btree ../../btree/bt_open.c +bt_overflow.o: ../../btree/bt_overflow.c + ${CL} -I../../btree ../../btree/bt_overflow.c +bt_page.o: ../../btree/bt_page.c + ${CL} -I../../btree ../../btree/bt_page.c +bt_put.o: ../../btree/bt_put.c + ${CL} -I../../btree ../../btree/bt_put.c +bt_search.o: ../../btree/bt_search.c + ${CL} -I../../btree ../../btree/bt_search.c +bt_seq.o: ../../btree/bt_seq.c + ${CL} -I../../btree ../../btree/bt_seq.c +bt_split.o: ../../btree/bt_split.c + ${CL} -I../../btree ../../btree/bt_split.c +bt_stack.o: ../../btree/bt_stack.c + ${CL} -I../../btree ../../btree/bt_stack.c +bt_utils.o: ../../btree/bt_utils.c + ${CL} -I../../btree ../../btree/bt_utils.c + +db.o: ../../db/db.c + ${CL} ../../db/db.c + +mpool.o: ../../mpool/mpool.c + ${CL} -I../../mpool ../../mpool/mpool.c + +rec_close.o: ../../recno/rec_close.c + ${CL} -I../../recno ../../recno/rec_close.c +rec_delete.o: ../../recno/rec_delete.c + ${CL} -I../../recno ../../recno/rec_delete.c +rec_get.o: ../../recno/rec_get.c + ${CL} -I../../recno ../../recno/rec_get.c +rec_open.o: ../../recno/rec_open.c + ${CL} -I../../recno ../../recno/rec_open.c +rec_put.o: ../../recno/rec_put.c + ${CL} -I../../recno ../../recno/rec_put.c +rec_search.o: ../../recno/rec_search.c + ${CL} -I../../recno ../../recno/rec_search.c +rec_seq.o: ../../recno/rec_seq.c + ${CL} -I../../recno ../../recno/rec_seq.c +rec_utils.o: ../../recno/rec_utils.c + ${CL} -I../../recno ../../recno/rec_utils.c + +memmove.o: + ${CC} -DMEMMOVE -c -O -I. -Iinclude clib/memmove.c +mktemp.o: + ${CC} -c -O -I. -Iinclude clib/mktemp.c +snprintf.o: + ${CC} -c -O -I. -Iinclude clib/snprintf.c diff --git a/db.1.85/PORT/aix.3.2/clib b/db.1.85/PORT/aix.3.2/clib new file mode 120000 index 0000000..f0f4f38 --- /dev/null +++ b/db.1.85/PORT/aix.3.2/clib @@ -0,0 +1 @@ +../clib \ No newline at end of file diff --git a/db.1.85/PORT/aix.3.2/include/cdefs.h b/db.1.85/PORT/aix.3.2/include/cdefs.h new file mode 120000 index 0000000..d248490 --- /dev/null +++ b/db.1.85/PORT/aix.3.2/include/cdefs.h @@ -0,0 +1 @@ +../../include/cdefs.h \ No newline at end of file diff --git a/db.1.85/PORT/aix.3.2/include/compat.h b/db.1.85/PORT/aix.3.2/include/compat.h new file mode 100644 index 0000000..2bd360a --- /dev/null +++ b/db.1.85/PORT/aix.3.2/include/compat.h @@ -0,0 +1,231 @@ +/*- + * Copyright (c) 1991, 1993 + * The Regents of the University of California.

+.br +int lorder; +.RE +} BTREEINFO; +.PP +The elements of this structure are as follows: +.TP +flags +The flag value is specified by +.IR or 'ing +any of the following values: +.RS +.TP +R_DUP +Permit duplicate keys in the tree, i.e. permit insertion if the key to be +inserted already exists in the tree. +The default behavior, as described in +.IR dbopen (3), +is to overwrite a matching key when inserting a new key or to fail if +the R_NOOVERWRITE flag is specified. +The R_DUP flag is overridden by the R_NOOVERWRITE flag, and if the +R_NOOVERWRITE flag is specified, attempts to insert duplicate keys into +the tree will fail. +.IP +If the database contains duplicate keys, the order of retrieval of +key/data pairs is undefined if the +.I get +routine is used, however, +.I seq +routine calls with the R_CURSOR flag set will always return the logical +``first'' of any group of duplicate keys. +.RE +.TP +cachesize +A suggested maximum size (in bytes) of the memory cache. +This value is +.B only +advisory, and the access method will allocate more memory rather than fail. +Since every search examines the root page of the tree, caching the most +recently used pages substantially improves access time. +In addition, physical writes are delayed as long as possible, so a moderate +cache can reduce the number of I/O operations significantly. +Obviously, using a cache increases (but only increases) the likelihood of +corruption or lost data if the system crashes while a tree is being modified. +If +.I cachesize +is 0 (no size is specified) a default cache is used. +.TP +maxkeypage +The maximum number of keys which will be stored on any single page. +Not currently implemented. +.\" The maximum number of keys which will be stored on any single page. +.\" Because of the way the btree data structure works, +.\" .I maxkeypage +.\" must always be greater than or equal to 2. +.\" If +.\" .I maxkeypage +.\" is 0 (no maximum number of keys is specified) the page fill factor is +.\" made as large as possible (which is almost invariably what is wanted). +.TP +minkeypage +The minimum number of keys which will be stored on any single page. +This value is used to determine which keys will be stored on overflow +pages, i.e. if a key or data item is longer than the pagesize divided +by the minkeypage value, it will be stored on overflow pages instead +of in the page itself. +If +.I minkeypage +is 0 (no minimum number of keys is specified) a value of 2 is used. +.TP +psize +Page size is the size (in bytes) of the pages used for nodes in the tree. +The minimum page size is 512 bytes and the maximum page size is 64K. +If +.I psize +is 0 (no page size is specified) a page size is chosen based on the +underlying file system I/O block size. +.TP +compare +Compare is the key comparison function. +It must return an integer less than, equal to, or greater than zero if the +first key argument is considered to be respectively less than, equal to, +or greater than the second key argument. +The same comparison function must be used on a given tree every time it +is opened. +If +.I compare +is NULL (no comparison function is specified), the keys are compared +lexically, with shorter keys considered less than longer keys. +.TP +prefix +Prefix is the prefix comparison function. +If specified, this routine must return the number of bytes of the second key +argument which are necessary to determine that it is greater than the first +key argument. +If the keys are equal, the key length should be returned. +Note, the usefulness of this routine is very data dependent, but, in some +data sets can produce significantly reduced tree sizes and search times. +If +.I prefix +is NULL (no prefix function is specified), +.B and +no comparison function is specified, a default lexical comparison routine +is used. +If +.I prefix +is NULL and a comparison routine is specified, no prefix comparison is +done. +.TP +lorder +The byte order for integers in the stored database metadata. +The number should represent the order as an integer; for example, +big endian order would be the number 4,321. +If +.I lorder +is 0 (no order is specified) the current host order is used. +.PP +If the file already exists (and the O_TRUNC flag is not specified), the +values specified for the parameters flags, lorder and psize are ignored +in favor of the values used when the tree was created. +.PP +Forward sequential scans of a tree are from the least key to the greatest. +.PP +Space freed up by deleting key/data pairs from the tree is never reclaimed, +although it is normally made available for reuse. +This means that the btree storage structure is grow-only. +The only solutions are to avoid excessive deletions, or to create a fresh +tree periodically from a scan of an existing one. +.PP +Searches, insertions, and deletions in a btree will all complete in +O lg base N where base is the average fill factor. +Often, inserting ordered data into btrees results in a low fill factor. +This implementation has been modified to make ordered insertion the best +case, resulting in a much better than normal page fill factor. +.SH ERRORS +The +.I btree +access method routines may fail and set +.I errno +for any of the errors specified for the library routine +.IR dbopen (3). +.SH "SEE ALSO" +.IR dbopen (3), +.IR hash (3), +.IR mpool (3), +.IR recno (3) +.sp +.IR "The Ubiquitous B-tree" , +Douglas Comer, ACM Comput.
