remove race conditions on connection close.
BROKEN: various counters for dn=monitor.
Initial testing on FreeBSD (with and without pthreads) was successfull.
Have not yet tested preemptive threading environments.
Have not built against backends other than LDBM.
utility functions added to support the modrdn v3 implementation.
These parse and rdn of the form "attribute_type = attribute_value"
returning "attribute_type" and "attribute_value" respectively.
cache_set_state() and state args are no history.
Move cache_entry_cmp() and friends to slapd/entry.c to allow sharing
of functions between backends.. Renamed to entry_cmp().
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.
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
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.
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.
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.
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.
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>
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.
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!
