Also, since swig_type_info structures store pointers to - * swig_cast_info structures and swig_cast_info structures store pointers back - * to swig_type_info structures, we need some lookup code at initialization. - * The idea is that swig generates all the structures that are needed. - * The runtime then collects these partially filled structures. - * The SWIG_InitializeModule function takes these initial arrays out of - * swig_module, and does all the lookup, filling in the swig_module.types - * array with the correct data and linking the correct swig_cast_info - * structures together. - * - * The generated swig_type_info structures are assigned staticly to an initial - * array. We just loop through that array, and handle each type individually. - * First we lookup if this type has been already loaded, and if so, use the - * loaded structure instead of the generated one. Then we have to fill in the - * cast linked list. The cast data is initially stored in something like a - * two-dimensional array. Each row corresponds to a type (there are the same - * number of rows as there are in the swig_type_initial array). Each entry in - * a column is one of the swig_cast_info structures for that type. - * The cast_initial array is actually an array of arrays, because each row has - * a variable number of columns. So to actually build the cast linked list, - * we find the array of casts associated with the type, and loop through it - * adding the casts to the list. The one last trick we need to do is making - * sure the type pointer in the swig_cast_info struct is correct. - * - * First off, we lookup the cast->type name to see if it is already loaded. - * There are three cases to handle: - * 1) If the cast->type has already been loaded AND the type we are adding - * casting info to has not been loaded (it is in this module), THEN we - * replace the cast->type pointer with the type pointer that has already - * been loaded. - * 2) If BOTH types (the one we are adding casting info to, and the - * cast->type) are loaded, THEN the cast info has already been loaded by - * the previous module so we just ignore it. - * 3) Finally, if cast->type has not already been loaded, then we add that - * swig_cast_info to the linked list (because the cast->type) pointer will - * be correct. - * ----------------------------------------------------------------------------- */ - -#ifdef __cplusplus -extern "C" { -#if 0 -} /* c-mode */ -#endif -#endif - -#if 0 -#define SWIGRUNTIME_DEBUG -#endif - - -SWIGRUNTIME void -SWIG_InitializeModule(void *clientdata) { - size_t i; - swig_module_info *module_head, *iter; - int found, init; - - clientdata = clientdata; - - /* check to see if the circular list has been setup, if not, set it up */ - if (swig_module.next==0) { - /* Initialize the swig_module */ - swig_module.type_initial = swig_type_initial; - swig_module.cast_initial = swig_cast_initial; - swig_module.next = &swig_module; - init = 1; - } else { - init = 0; - } - - /* Try and load any already created modules */ - module_head = SWIG_GetModule(clientdata); - if (!module_head) { - /* This is the first module loaded for this interpreter */ - /* so set the swig module into the interpreter */ - SWIG_SetModule(clientdata, &swig_module); - module_head = &swig_module; - } else { - /* the interpreter has loaded a SWIG module, but has it loaded this one?

tdb

- -TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB -except that it allows multiple simultaneous writers and uses locking -internally to keep writers from trampling on each other. TDB is also extremely -small. - -

Discussion and bug reports

- -tdb does not currently have its own mailing list or bug tracking -system. For now, please use the samba-technical -mailing list, and the Samba -bugzilla bug tracking system. - -

Download

- -You can download the latest release either via rsync or git.
-
-To fetch via git see the following guide:
-Using Git for Samba Development
-Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/tdb directory.
-
-To fetch via rsync use these commands: - -
-  rsync -Pavz samba.org::ftp/unpacked/tdb .
-  rsync -Pavz samba.org::ftp/unpacked/libreplace .
-
- -and build in tdb. It will find the replace library in the directory -above automatically. - - - diff --git a/source3/samba4.m4 b/source3/samba4.m4 index 86047c19a6..ffc93af748 100644 --- a/source3/samba4.m4 +++

Also, since swig_type_info structures store pointers to - * swig_cast_info structures and swig_cast_info structures store pointers back - * to swig_type_info structures, we need some lookup code at initialization. - * The idea is that swig generates all the structures that are needed. - * The runtime then collects these partially filled structures. - * The SWIG_InitializeModule function takes these initial arrays out of - * swig_module, and does all the lookup, filling in the swig_module.types - * array with the correct data and linking the correct swig_cast_info - * structures together. - * - * The generated swig_type_info structures are assigned staticly to an initial - * array. We just loop through that array, and handle each type individually. - * First we lookup if this type has been already loaded, and if so, use the - * loaded structure instead of the generated one. Then we have to fill in the - * cast linked list. The cast data is initially stored in something like a - * two-dimensional array. Each row corresponds to a type (there are the same - * number of rows as there are in the swig_type_initial array). Each entry in - * a column is one of the swig_cast_info structures for that type. - * The cast_initial array is actually an array of arrays, because each row has - * a variable number of columns. So to actually build the cast linked list, - * we find the array of casts associated with the type, and loop through it - * adding the casts to the list. The one last trick we need to do is making - * sure the type pointer in the swig_cast_info struct is correct. - * - * First off, we lookup the cast->type name to see if it is already loaded. - * There are three cases to handle: - * 1) If the cast->type has already been loaded AND the type we are adding - * casting info to has not been loaded (it is in this module), THEN we - * replace the cast->type pointer with the type pointer that has already - * been loaded. - * 2) If BOTH types (the one we are adding casting info to, and the - * cast->type) are loaded, THEN the cast info has already been loaded by - * the previous module so we just ignore it. - * 3) Finally, if cast->type has not already been loaded, then we add that - * swig_cast_info to the linked list (because the cast->type) pointer will - * be correct. - * ----------------------------------------------------------------------------- */ - -#ifdef __cplusplus -extern "C" { -#if 0 -} /* c-mode */ -#endif -#endif - -#if 0 -#define SWIGRUNTIME_DEBUG -#endif - - -SWIGRUNTIME void -SWIG_InitializeModule(void *clientdata) { - size_t i; - swig_module_info *module_head, *iter; - int found, init; - - clientdata = clientdata; - - /* check to see if the circular list has been setup, if not, set it up */ - if (swig_module.next==0) { - /* Initialize the swig_module */ - swig_module.type_initial = swig_type_initial; - swig_module.cast_initial = swig_cast_initial; - swig_module.next = &swig_module; - init = 1; - } else { - init = 0; - } - - /* Try and load any already created modules */ - module_head = SWIG_GetModule(clientdata); - if (!module_head) { - /* This is the first module loaded for this interpreter */ - /* so set the swig module into the interpreter */ - SWIG_SetModule(clientdata, &swig_module); - module_head = &swig_module; - } else { - /* the interpreter has loaded a SWIG module, but has it loaded this one?

tdb

- -TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB -except that it allows multiple simultaneous writers and uses locking -internally to keep writers from trampling on each other. TDB is also extremely -small. - -

Discussion and bug reports

- -tdb does not currently have its own mailing list or bug tracking -system. For now, please use the samba-technical -mailing list, and the Samba -bugzilla bug tracking system. - -

Download

- -You can download the latest release either via rsync or git.
-
-To fetch via git see the following guide:
-Using Git for Samba Development
-Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/tdb directory.
-
-To fetch via rsync use these commands: - -
-  rsync -Pavz samba.org::ftp/unpacked/tdb .
-  rsync -Pavz samba.org::ftp/unpacked/libreplace .
-
- -and build in tdb. It will find the replace library in the directory -above automatically. - - - diff --git a/source4/lib/tdb_wrap.c b/source4/lib/tdb_wrap.c index 37095dff2c..fadf1736dc 100644 --- a/source4/lib/tdb_wrap.c +++ b/source4/lib/tdb_wrap.c @@ -20,7 +20,7 @@ */ #include "includes.h" -#include "lib/tdb/include/tdb.h" +#include "../tdb/include/tdb.h" #include "lib/util/dlinklist.h" #include "tdb_wrap.h" #include "tdb.h" diff --git a/source4/lib/util/util_tdb.c b/source4/lib/util/util_tdb.c index e4219dfd69..e89085a31b 100644 --- a/source4/lib/util/util_tdb.c +++ b/source4/lib/util/util_tdb.c @@ -20,7 +20,7 @@ */ #include "includes.h" -#include "lib/tdb/include/tdb.h" +#include "../tdb/include/tdb.h" #include "pstring.h" #include "lib/util/util_tdb.h" diff --git a/source4/param/secrets.c b/source4/param/secrets.c index 16fbb3b108..45d3765b7a 100644 --- a/source4/param/secrets.c +++ b/source4/param/secrets.c @@ -27,7 +27,7 @@ #include "system/filesys.h" #include "tdb_wrap.h" #include "lib/ldb/include/ldb.h" -#include "lib/tdb/include/tdb.h" +#include "../tdb/include/tdb.h" #include "lib/util/util_tdb.h" #include "lib/util/util_ldb.h" #include "librpc/gen_ndr/ndr_security.h" diff --git a/source4/smbd/process_prefork.c b/source4/smbd/process_prefork.c index 2ffb724a6c..0d17e5301d 100644 --- a/source4/smbd/process_prefork.c +++ b/source4/smbd/process_prefork.c @@ -25,7 +25,7 @@ #include "includes.h" #include "lib/events/events.h" -#include "lib/tdb/include/tdb.h" +#include "../tdb/include/tdb.h" #include "lib/socket/socket.h" #include "smbd/process_model.h" #include "param/secrets.h" diff --git a/source4/smbd/process_standard.c b/source4/smbd/process_standard.c index 3f2936bb26..c8f90209b6 100644 --- a/source4/smbd/process_standard.c +++ b/source4/smbd/process_standard.c @@ -23,7 +23,7 @@ #include "includes.h" #include "lib/events/events.h" -#include "lib/tdb/include/tdb.h" +#include "../tdb/include/tdb.h" #include "lib/socket/socket.h" #include "smbd/process_model.h" #include "param/secrets.h" diff --git a/tdb/Makefile.in b/tdb/Makefile.in new file mode 100644 index 0000000000..090bb6e2dc --- /dev/null +++ b/tdb/Makefile.in @@ -0,0 +1,59 @@ +#!gmake +# +# Makefile for tdb directory +# + +CC = @CC@ +prefix = @prefix@ +exec_prefix = @exec_prefix@ +bindir = @bindir@ +includedir = @includedir@ +libdir = @libdir@ +VPATH = @srcdir@:@libreplacedir@ +srcdir = @srcdir@ +builddir = @builddir@ +CPPFLAGS = @CPPFLAGS@ -I$(srcdir)/include -Iinclude +CFLAGS = $(CPPFLAGS) @CFLAGS@ +LDFLAGS = @LDFLAGS@ +EXEEXT = @EXEEXT@ +SHLD = @SHLD@ +SHLD_FLAGS = @SHLD_FLAGS@ +PACKAGE_VERSION = @PACKAGE_VERSION@ +PICFLAG = @PICFLAG@ +SHLIBEXT = @SHLIBEXT@ +SWIG = swig +PYTHON = @PYTHON@ +PYTHON_CONFIG = @PYTHON_CONFIG@ +PYTHON_BUILD_TARGET = @PYTHON_BUILD_TARGET@ +PYTHON_INSTALL_TARGET = @PYTHON_INSTALL_TARGET@ +PYTHON_CHECK_TARGET = @PYTHON_CHECK_TARGET@ +LIB_PATH_VAR = @LIB_PATH_VAR@ +tdbdir = @tdbdir@ + +TDB_OBJ = @TDB_OBJ@ @LIBREPLACEOBJ@ + +default: all + +include $(tdbdir)/tdb.mk +include $(tdbdir)/rules.mk + +all:: showflags dirs $(PROGS) $(TDB_SOLIB) libtdb.a $(PYTHON_BUILD_TARGET) + +install:: all +$(TDB_SOLIB): $(TDB_OBJ) + $(SHLD) $(SHLD_FLAGS) -o $@ $(TDB_OBJ) @SONAMEFLAG@$(TDB_SONAME) + +check: test + +test:: $(PYTHON_CHECK_TARGET) +installcheck:: test install + +clean:: + rm -f *.o *.a */*.o + +distclean:: clean + rm -f config.log config.status include/config.h config.cache + rm -f Makefile + +realdistclean:: distclean + rm -f configure include/config.h.in diff --git a/tdb/aclocal.m4 b/tdb/aclocal.m4 new file mode 100644 index 0000000000..5605e476ba --- /dev/null +++ b/tdb/aclocal.m4 @@ -0,0 +1 @@ +m4_include(libreplace.m4) diff --git a/tdb/autogen.sh b/tdb/autogen.sh new file mode 100755 index 0000000000..88ac4cfcf7 --- /dev/null +++ b/tdb/autogen.sh @@ -0,0 +1,16 @@ +#!/bin/sh + +rm -rf autom4te.cache +rm -f configure config.h.in + +IPATHS="-I libreplace -I lib/replace -I ../libreplace -I ../replace" +autoconf $IPATHS || exit 1 +autoheader $IPATHS || exit 1 + +rm -rf autom4te.cache + +swig -O -Wall -python -keyword tdb.i # Ignore errors for now + +echo "Now run ./configure and then make." +exit 0 + diff --git a/tdb/common/dump.c b/tdb/common/dump.c new file mode 100644 index 0000000000..d1c902ddfd --- /dev/null +++ b/tdb/common/dump.c @@ -0,0 +1,137 @@ + /* + Unix SMB/CIFS implementation. + + trivial database library + + Copyright (C) Andrew Tridgell 1999-2005 + Copyright (C) Paul `Rusty' Russell 2000 + Copyright (C) Jeremy Allison 2000-2003 + + ** NOTE!

It was inspired by the realisation that +in Samba we have several ad-hoc bits of code that essentially +implement small databases for sharing structures between parts of +Samba. As I was about to add another I realised that a generic +database module was called for to replace all the ad-hoc bits. + +I based the interface on gdbm.

The tdb_open call is more similar to a + traditional open() +- no tdbm_reorganise() function +- no tdbm_sync() function. No operations are cached in the library anyway +- added a tdb_traverse() function for traversing the whole database +- added transactions support + +A general rule for using tdb is that the caller frees any returned +TDB_DATA structures.

Also, since swig_type_info structures store pointers to + * swig_cast_info structures and swig_cast_info structures store pointers back + * to swig_type_info structures, we need some lookup code at initialization. + * The idea is that swig generates all the structures that are needed. + * The runtime then collects these partially filled structures. + * The SWIG_InitializeModule function takes these initial arrays out of + * swig_module, and does all the lookup, filling in the swig_module.types + * array with the correct data and linking the correct swig_cast_info + * structures together. + * + * The generated swig_type_info structures are assigned staticly to an initial + * array. We just loop through that array, and handle each type individually. + * First we lookup if this type has been already loaded, and if so, use the + * loaded structure instead of the generated one. Then we have to fill in the + * cast linked list. The cast data is initially stored in something like a + * two-dimensional array. Each row corresponds to a type (there are the same + * number of rows as there are in the swig_type_initial array). Each entry in + * a column is one of the swig_cast_info structures for that type. + * The cast_initial array is actually an array of arrays, because each row has + * a variable number of columns. So to actually build the cast linked list, + * we find the array of casts associated with the type, and loop through it + * adding the casts to the list. The one last trick we need to do is making + * sure the type pointer in the swig_cast_info struct is correct. + * + * First off, we lookup the cast->type name to see if it is already loaded. + * There are three cases to handle: + * 1) If the cast->type has already been loaded AND the type we are adding + * casting info to has not been loaded (it is in this module), THEN we + * replace the cast->type pointer with the type pointer that has already + * been loaded. + * 2) If BOTH types (the one we are adding casting info to, and the + * cast->type) are loaded, THEN the cast info has already been loaded by + * the previous module so we just ignore it. + * 3) Finally, if cast->type has not already been loaded, then we add that + * swig_cast_info to the linked list (because the cast->type) pointer will + * be correct. + * ----------------------------------------------------------------------------- */ + +#ifdef __cplusplus +extern "C" { +#if 0 +} /* c-mode */ +#endif +#endif + +#if 0 +#define SWIGRUNTIME_DEBUG +#endif + + +SWIGRUNTIME void +SWIG_InitializeModule(void *clientdata) { + size_t i; + swig_module_info *module_head, *iter; + int found, init; + + clientdata = clientdata; + + /* check to see if the circular list has been setup, if not, set it up */ + if (swig_module.next==0) { + /* Initialize the swig_module */ + swig_module.type_initial = swig_type_initial; + swig_module.cast_initial = swig_cast_initial; + swig_module.next = &swig_module; + init = 1; + } else { + init = 0; + } + + /* Try and load any already created modules */ + module_head = SWIG_GetModule(clientdata); + if (!module_head) { + /* This is the first module loaded for this interpreter */ + /* so set the swig module into the interpreter */ + SWIG_SetModule(clientdata, &swig_module); + module_head = &swig_module; + } else { + /* the interpreter has loaded a SWIG module, but has it loaded this one?

tdb

+ +TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB +except that it allows multiple simultaneous writers and uses locking +internally to keep writers from trampling on each other. TDB is also extremely +small. + +

Discussion and bug reports

+ +tdb does not currently have its own mailing list or bug tracking +system. For now, please use the samba-technical +mailing list, and the Samba +bugzilla bug tracking system. + +

Download

+ +You can download the latest release either via rsync or git.
+
+To fetch via git see the following guide:
+Using Git for Samba Development
+Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/tdb directory.
+
+To fetch via rsync use these commands: + +
+  rsync -Pavz samba.org::ftp/unpacked/tdb .
+  rsync -Pavz samba.org::ftp/unpacked/libreplace .
+
+ +and build in tdb. It will find the replace library in the directory +above automatically. + + + -- cgit
