Move cache_return_entry_w() out of ldbm_back_add when the add is successful.
This change breaks back-bdb2, it needs equvalent changes of those in back-ldbm.
Move all SunOS routines (ie: _sleep() and its helpers) to thr_lwp.c
so that it's internals can be 'static'. Add 'static' to thr_lwp.c.
Add comment to LWP: NEEDS WORK, may not compile! Need some
SunOS user to sort out the details. Volunteers?
Added call to perl "config" method so the the
perl module can have its own configuration
options.
Fix bug in init.c where the address of the be_private
object was being retrieved when it was already
a pointer.
Added the dn parameter to the modify.c call to the
modify method. Not sure why this wasn't there
in the beginning.
Expects and array from the search method instead of
a scalar in search.c so that it can return search
results and a return code.
Added the demo file SampleLDAP.pm
id2entry: when an error occurs attempting to insert fetched
entry into cache, check to see if entry was added by another
thread. If so, return the entry added by the other thread.
The concurrency tests now run without the dreaded "no such object"
error messages!
Removed external include/library paths from projects. External paths should
be set via Tools | Options | Directories. This allows each developer the
freedom to install external libraries where they desire.
Used libdb.lib instead of libdbs.lib to avoid thread conflicts.
Added hs_regex.lib to library input. We require some form of regex, this
library works (and is relatively easy for the user to install).
Removed a little lint which MCVC5 detected.
Need to sort out single-threaded vs multithreaded library generation.
tcp_close -> closesocket
ioctl -> ioctlsocket
Modify codes to use tcp_close() instead of close() for sockets.
Modify ioctl codes to be compatible with WINSOCK.
library, not header. Eliminate need for <ac/unistd.h> to sometimes
include <fcntl.h> and/or <sys/file.h>. Change lock API to expect
fd not FILE*. Allows wider use and eliminates requirement that
lutil_lockf.h depencency on stdio.h.
Implemented lockf, fcntl, and flock locking in lutil/lockf.c.
Additional implementations (including no-op) may be needed.
Update slapd/lock.c and slurpd/lock.c to use new API.
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.
by portable.h with NDEBUG undefined. This makes assert() is always
available and automatically disables itself when LDAP_DEBUG is undefined.
I've included a basic assert() for pre-STDC compilers. It relies on
abort() which may not actually be available. (well replace abort()
with whatever is appropriate if and when we're faced with a pre-STDC
compiler that doesn't have assert()).
address. Useful for running multiple servers in a virtual hosting
environment.
Modified test001-ldif2ldbm to verify this functionality. Assumes
localhost is 127.0.0.1.
SLAP_C_ACTIVE vs SLAP_C_INACTIVE. Need to implement BINDING and CLOSING.
Added fields tracking pending (on bind) ops. Could also be used to
implement per-connection thread limits.
lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
If it remains, it needs to be written to support various methods for
setting non-blocking. ioctls should probably be last choice. configure
could detect existance of fcntl(), ioctl(), etc.
bdb2:
added .dsp/.dsw files and did some basic cleanup (still needs work).
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.
Implementation no longer uses strtok_r(), it may be broken
or have an odd prototype.
Update configure not to check for strtok/strtok_r nor require
strtok_r to LDAP_API_FEATURE_X_OPENLDAP_REENTRANT.
* Fixed unfree'd 'char *results' in all tcl_* functions (only unfree'd in
certain cases, moved the free to the actual function) so no more mem
leaks. Tested this with over 500,000 access's for testing :)
* Miscellaneous source style and tabulation fixes
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().
The new e_private field can be used for any backend purpose. In LDBM,
it's used to point th the private entry info struct. The LDBM entry
info struct is only visible to the LDBM cache.
WARNING: This change has not be ported to other backends! Breakage is likely.
Integration into ./configure ( --enable-bdb2 ).
Adaptation of the test-suite ( 'make' -> ldbm; 'make bdb2-local' -> bdb2 ).
Minor fixes in slapd/libldbm.
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).
