BEWARE: the backend will be compiled.
the backend will NOT be invoked, yet.
the backend CANNOT be invoked, yet, because it is NOT yet
integrated into the new initialization/startup environment
of the slapd server.
Separates per backend type from per backend database initialization
and startup. Also supports per type / per backend shutdown.
New frontend startup/shutdown routines are also provided:
slap_init() slap_startup() slap_shutdown() slap_destroy()
New frontend->backend startup/shutdown is managed by:
backend_init() backend_startup() backend_shutdown backend_destroy
backend_init() now calls bi_init() to initial all function pointers
for the backend (excepting bi_init() which is now the only hardcoded
entry point). New entry points are detailed in slap.h struct
backend_info. backend_info is a per database type structure.
Besides the new startup/shutdown entry points, the new interface
also supports per backend type configuration options. One could have:
backend bdb2 (new Berkeley DB 2 backend)
bdb2_home /directory
database bdb2
...
*** This code is fairly experimental ***
*** Much cleanup and testing is still needed ***
see slap.h for details on struct backend_db and backend_info.
okay to read and write LDBM specific fields (state, refcnt,
LRU. The id field, though is read-only once set.
cache_find_entry_dn2id(), hence, does not require any entry locks.
cache_find_entry_id() must do a entry_rdwr_trylock() and back
off if busy.
Add new rdwr lock code with trylock() functionality.
Implement entry_rdwr_trylock().
Fix idl_nextid not to skip an ID if ID not in list.
Both of these should not occur if used correctly, but cheap insurance
against incorrect usage is welcomed.
instead of array with overlayed struct fields. (which is inherently
non-portable).
Change maxid check in insert to be greater than or equal instead
of equal.
Use SAFEMEMCPY.
Likely broke things for non-posix threadings....
Update -lldap_r implementation to:
remove attribute support
hide thread detachment
provide concurrency accessors
provide initialization function
fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread
back-ldbm was using a cache specific lock to protect non-reentrant
database routines from being reenterred. This is inadequate.
Also, reentrant database systems calls were serialized unnecessarily.
Non-reentrant database calls must have a big_mutex. Implemented
this within -lldbm itself. library requires ldbm_initialize()
be called before any other ldbm call to initialize the big_mutex
and to do any other db specific initialization (ie: such as
required for DB2).
The dbc_mutex, dbc_cv, & dbc_readers fileds of dbcache are history.
The "reentrant_database" (REENTRANT_DATABASE) define is also axed.
behind REENTRANT_DATABASE. rename reentrant_database -> REENTRANT_DATABASE.
When REENTRANT_DATABASE is defined, the simple lock is replaced
with a simple reader/writer lock. This functionality should be removed
from back-ldbm to libldbm.
SLAPD_NEXTID_CHUNK. Code protects NEXTID file to ensure
its equal to or greater than nextid. Updated on close
to actual nextid. next_id_save() could be called periodically
if desired. Default chunk size is 32. Define to 1 to disable
chunking.
introduction of pid/agrs parameters to the test-suite slapd.conf files;
creation of sub-directory test/var for storage of pid/args files during test;
update of the slapd and slapd.conf man pages.
(The change reduces dependency on ldapconfig.h, since SLAPD_PIDEXT
and SLAPD_ARGSEXT are deleted from the code.)
Update slap_op to maintain dn and ndn (derived from conn->c_dn).
Update ldbm_back_bind to return actual bound dn (including rootdn)
for use in slapd_conn. Other backends use client dn.
Modify other codes to use ndn (normalized uppercase dn) most everywhere.
Aliasing, Suffixing and modrdn could use more work.
Applied suffixing to compare and modrdn.
end of link. Basic order is:
$LDFLAGS internal-libs external-libs $LIBS $LTHREAD_LIBS
LTHREAD_LIBS is last as -lpthread (or equiv) must be last on many systems.
LIBS is next to last as some user might have put -lpthread (or equiv)
in $LIBS.
creation codes to provide this field. Update cache_entrydn_cmp
to strcasecmp() the e_ndn instead of e_dn. Note: strcasecmp()
is still used as e_ndn isn't in uppercase. Maybe it should
be. Did not update other codes to use e_ndn. Hence, there
are lots of dn_normalize() calls that could be eliminated.
(The case determination of e_ndn should be made first).
creating them detached. This hopefully will reduce problems on
draft4 pthread implementations related to creating detached
threads (which is _np under draft4) on some platforms without
causing problems with other thread implementations.
of a busy wait and allow the pthread_yield within the loop to be
removed. This was the only pthread_yield which was necessary
when usng non-preemptive threads. As such, the configure.in
sched_yield/pthread_yield missing error can be removed from
configure.in. If explicit yield function is missing, just provide
a no-op replacement.
Moved declaration of various slapd globals from main.c to init.c
so they can be shared with ldbm tools.
make depend, make tests, and make install all work when build directory
is not the $srcdir.
Also modified library handling such that -lpthread more likely to be last.
WARNING: new orderring requires use of LDFLAGS to set global loader options
such as -L/usr/local/lib. If you put this in LIBS, some libraries
may not be found a link time.
Likely broke Kerberos/LDAPD support. Don't have those in my testbed.
rename 'struct conn' to 'struct slap_conn'
rename op_function to slap_op_func for functions add/delete/free
This change is need to avoid clashing with perl internals.
parent's "children" attribute. Write lock parent to prevent
multiple clients making conflicting operations concurrently.
If parent doesn't exist (ie: is backend root), acquire a writer
lock (a simple mutex) on the "root."
Use -DSLAPD_CHILD_MODIFICATION_WITH_ENTRY_ACL to use the child's
"entry" acl for modrdn/delete operations.
- slapd's pid/args file names are based on the servers binary file names,
providing for multiple servers beeing run on one host.
- slapd supports the -l command line parameter for selection of a
syslog LOCAL user (-lLOCAL0 .. -lLOCAL7)
- db_appinit() is called during first ldbm_open() in DB 2.x to initialize
DB debugging features (good to find bugs in the DB code :-)
- a patch for a non-initialized variable in DB's 2.x db_open is provided.
Resolved deadlock by passing target entry to be_group and using
this if dn same as bdn. It might actually be safer to check
entry ids instead of dns.
Resolved bogus add to cache after failed acl check by deferring
cache add until after parent/acl checks have successful been
completed.
Eliminated race condition caused by concurrent adds
of same dn by adding 'li_add_mutex' around the critical section
of code (most of ldbm_back_add).
This code is preliminary and still needs significant testing.
Seems that calling pthread_exit() in the main (and only active)
thread does not cause the whole process to exit. Very odd.
Anyways, as we want to whole process to exit, we should just exit
after joining with our other threads.
I've also removed dead code for detaching threads we join with.
add/merge as we now free strings agressively. Improved debug
message to include name of missing required attribute and added
check for 'operational attributes'. This check should be used
everywhere we need to test for operational attributes (add/modify).
Also, enabled schema checking for tests (and fixed resulting
problems by adjusting oc.conf).
struct friendly (Friendly) changed to ldap_friendly (LDAPFriendly)
ldap_friendly friend prefix changed to 'lf_' from 'f_'
removed mod_next field from LDAPMod (struct ldapmod)
modified slapd to use new LDAPModList (struct ldapmodlist) struct.
Added LDAPv3 result codes to ldap.h
incorrect because value_cmp() in value.c compares two attributes by
comparing the leading bytes of the two values (candidate and filter) up to
the smaller of the two lengths of the binary values. If the lengths of two
SYNTAX_BIN values differ, like SYNTAX_CES and SYNTAX_CIS, the EQUALITY
comparison should fail.
It also appears that value_ncmp() in value.c has no references anywhere in
the openLDAP source tree, save for a definition in proto-slap.h. The
following fix the bug and remove the dead code:
From: "MCGARRAHAN, KENNETH L" <km4155@momail.sbc.com>
"Check that the entry has no writers before removing it from the
cache" sounds more sensible to me than "check that it *has* writers"
before removing it.
I've also changed the default cachesize for tests to 4. This
should help discover such problems.
Remove MD5 and SHA1 options (both are now always on). Rename
functions to be lutil_ instead of ldap_.
Create --enable-cleartext option. Default is currently 'on'.
default sysconfdir subdirectory is openldap instead of ldap.
This removes conflicts with other ldap subsystems. Should
be configure option.
*.conf files are now preserved. A *.conf.default are always
created with the latest conf.
*.help and ldapfriendly are now placed in $(datadir)/$(ldap_subdir)
updated man pages to reflect changes.
the exact nature of the functionality being tested. -DNO_THREADS
does NOT have a yield select, hence the macro is not defined.
The slapd/daemon code has been changed to test both no threads
and yielding select before using a timeout of NULL.
Updated to use libtool 1.2 (with FreeBSD3.0 a.out v. elf detection).
Updated autoconf to 1.12 with sed patch (don't use stock 1.12).
aclocal.m4 is built using automake's aclocal, v1.3.
Updated mkdep to support libtool .lo files.
Updated automake provided macros for TERMIOS, STRTOD, MKTIME, PTRDIFF_T
Autoconf now checks to ensure C compiler supports ANSI C prototypes.
Updated make files templates.
This could cause problems on odd systems. The generic
headers should be extended as needed to include necessary
system headers or, if necessary, make explicit declarations.
Extended ac/string.h header to look for string.h/strings.h if
STDC_HEADERS is not defined. Also provide basic declarations for
str*() functions. This could cause problems on odd systems.
Extended ac/unistd.h header to define basic declaration for misc
functions that might be missing from headers. This includes
externs for getenv(), getopt(), mktemp(), tempname().
Protect fax500.h from multiple inclusion. Moved includes of
system/generic headers back to source files.
Made mail500 helper functions static.
Fixed includes of ctype.h, signal.h, etc. to use generics.
lutil/tempname.c: was including stdlib.h twice, one should stdio.h.
Wrapped <sys/resource.h> with HAVE_SYS_RESOURCE_H.
lber/io.c/ber_get_next(): Changed noctets back to signed.
Used with BerRead which expects signed int as second arg and
returns signed int.
Most function and variable definitions are now preceded by its extern
definition, for error checking. Retyped a number of functions, usually
to return void. Fixed a number of printf format errors.
API changes (in ldap/include):
Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.
A number of `extern' declarations are left (some added by protoize), to
be cleaned away later. Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.
#include <stdlib.h> to get malloc & co various places,
#include <ac/string.h> to get strlen & co in (liblutil/setproctitle.c),
declare ch_malloc & co (slurp.h), avl_find_lin (avl.h), Malloc (ud/edit.c).
Also changed ch_malloc & co from char* to void* functions.
Fixed in slurpd and the slapd main dir. Slapd clients were not examined.
It also "felt right" to swap the order of closing dfp and rfp in slurpd
copy_replog(), so the last acquired lock is unlocked first.
-thread & -pthread are still treated as libraries, will need
additional work to use them as CFLAGS.
Eliminated HAVE_DCE define (was redundant) and its use. Code
now relies on draft4 and function existance tests.
Modified clients to reduce use of ldapconfig.h.edit.
ldap_{get,set}_option support is relatively complete. Needs
to be extended to support other "features" of OpenLDAP.
updated clients to use ldap_get/set_options
ld_options is renamed ld_booleans. ldap-int.h has accessor macros.
updated libldap to use new accessor macros.
SHA1 support is contributed by Daniel J. Gregor <dj@gregor.com>
MD5 support is contributed by me <kurt@OpenLDAP.org>
Uses public domain MD5 routines
Uses ISC/IBM freely redistributable Base64 routines
SHA1 support requires external SHA1 routines
adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however
we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!
