*** AOLserver 3.4.2 RELEASED ***
* Makefile: install rule depends on "all" rule for the benefit of
Macintosh OS 10.
* nsd/nsd.h: version and label to 3.4.2.
* nsd/tclnsshare.cpp, nsd/tclmisc.c: Fix for 3.4 ns_share problem
was not fully applied to 3.4.1.
2001-09-06 Kriston Rehberg <Kriston@AOL.NET>
*** AOLserver 3.4.1 RELEASED (internal testing release) ***
2001-09-05 Kriston Rehberg <Kriston@AOL.NET>
* nsd/tclnsshare.cpp: For ns_share Tcl command only; several crash
bugs fixed and cleaned up the code to better accomodate how
ns_share is used in real-world code. We still strongly discourage
the use of ns_share and a warning upon its first use per variable
is logged.

*** AOLserver 3.4 RELEASED ***
2001-05-17 Kris Rehberg <Kriston@AOL.NET>
* nsd/conn.c: conn is now aware of Latin-1 charsets for ADPs,
requests, query data, and the like in Tcl 8. This does not affect
IS0-8859-1 (see nsd/adp.c below).
(NsTclConnCmd): [ns_conn encoding] reports the encoding used (see
nsd/adp.c below).
* nsd/adp.c: The ADP requests, file parsing, file includes, and
all related ADP functions now force ISO-8859-1 for support of all
Latin-1 character sets in ADPs on nsd8x. There is new handling of
UTF data in Tcl 8 that was implemented in AOLserver 4 which has
been back-ported to support Latin-1 *only* in AOLserver 3.4.
Previously, nsd8x could not handle anything but 7-bit ASCII in
ADPs. The reading of Latin-1 charsets seemed to fail
intermittently in previous 3.x AOLservers. The reason was that
AOLserver reads files in as UTF-8 and some Latin-1 characters
confuse Tcl 8's UTF reader. (Note that the en-us characters in
Unicode, when encoded in UTF-8, look just like 7-bit US ASCII to
computers). Naturally, when non-en-us characters are encountered,
the Tcl 8 UTF-8 reader gets confused. The correct MIME type is
now returned for all Latin-1 charsets. This does not affect
IS0-8859-1.
* thread/pool.c, thread/pthread.cpp, thread/reentrant.c: Tls
entries for memory pools, thread pools, re-entrant libc
replacements, are self-initializing.
* thread/Makefile, tcl8.3.2/unix/Makefile.in: Moved Tcl nsthread
support into Tcl sources.
* tcl8.3.2/generic/tclEvent.c: Fixed library path code as in
AOLserver 4 so Tcl 8 can find encoding files for UTF in a
thread-safe manner.
* nsd/tclstubs.cpp: Back-ported some AOLserver 4 initialization
code. Tls self-initializes. UTF-aware encodings based on file
extension (from AOLserver 4). See nsd/adp.c below.
* nsd/tclinit.c: Tls entry for Tcl interps is self-initializing.
* nsd/nsmain.c: UTF encoding-aware (see nsd/adp.c below).
* nsd/nsd.h: New UTF encoding routines and version strings (see
nsd/adp.c below).
* nsd/dstring.c: NS_DStrings are self-initializing. You should
not need to use Ns_DStringInit anymore, though you still can with
no ill effect.
* nsd/dbinit.c (IncrCount): Tls entry for db handles is
self-initializing.
* nsd/adp.c: Tls entry for ADP parser is self-initializing.
2001-04-26 Kris Rehberg <Kriston@AOL.NET>
* AOLserver 3.4pre1 released. The ChangeLog will be updated in
the next release (see above).
2001-03-14 Kris Rehberg <Kriston@AOL.NET>
* nsd/nsmain.c, nsconf.h: non-quiet startup is now the default.
The -q option turns the annoying, noisy startup back on.
* include/Makefile.global: Makefile.global wasn't working on
OpenBSD 2.8. Got rid of -E and changed libtcl8.3g.a to
libtcl83g.a for all BSD platforms. Many thanks to John Borwick
for the patch!
* nsd/conn.c: Straightened out an error text while looking for
something else.
* nsd/serv.c: [ #232139 ] Buffer overflow in ParseAuth().
ParseAuth() uses a 256-byte buffer for decoding authentication
data. Unfortunately, Ns_HtuuDecode() does not do an adequate job
in preventing data overflow due to the way it tries to loop unroll
4-bytes per iteration. To reproduce: Using IE 5.xxx, navigate to
a page that challenges (ie 401 return). Fill the user/pwd fields
with as much data as possible. Hit return, and watch AOLserver die
due to stack corruption (on Linux, at least). It is preferable to
allocate the storage dynamically. Thanks to Adam Zell for the bug
report and patch!!
* generic/tclCmdIL.c (InfoProcsCmd): [ #230640 ] memory leak in
"info procs" command. Arsdigita plus-patches fixed a memory leak
in "info procs" command (in Tcl library). It neglects to free
memory after the "info procs" command is executed. nsd8x only.
Fixed via hack to Tcl8.3.2 in AOLserver 3.3 (Jim Davidson).
* thread/tcl8x.c: [ #406708 ] Tcl TSD data leaks on
thread-exit. Added new, custom per-thread Tcl_Obj allocator for
NsTclFinalizeThread(). Fixed is in 3.31 and 4.x. Check
thread/tcl8x.c for detailed comments. Thanks to Zoran Vasiljevic
for the bug report and suggesting a fix.
* tcl/namespace.tcl: [ #230624 ] Namespaces are not used properly.
There is a problem with current modules/tcl/namespace.tcl Instead
of correctly using namespace import/export capabilities, it just
makes a copy of each procedure found within a namespace, even it
is imported from a foreign namespace. This adds unnecessary heap
space to have each exported procedure body replicated in more than
one namespaces but what is worst, all imported procedures, instead
of running within their declaring namespace, as standard TCL does,
they will run in their caller namespaces. Thanks to Petrica
Clement for this fix!
2001-03-14 Dossy Shiobara <dossy@panoptic.com>
* nsd/nsmain.c: [ #230646 ] Specifying user/group dumps core on
Linux. Segmentation fault when using -g <group> flag
(reproducing this change from HEAD into the nsd_v3_r3_p0 branch)
line 316 should read Ns_GetGid(garg) instead of
Ns_GetGid(optarg). Thanks to Scott G and Dossy, and Daniel
P. Stasinski for this one.
2001-03-12 Kris Rehberg <Kriston@AOL.NET>
*** nsd_v3_r3_p0 (AOLserver 3.3.0) BRANCH BEGINS ***
2001-03-08 Kris Rehberg <Kriston@AOL.NET>
*** AOLserver 3.3 RELEASED ***
2001-03-08 Jim Davidson
* Added NsTclFinalizeThread() at end of Tcl TLS cleanup to
finalize Tcl 8.x thread data. This fix was the last hurdle for
finalizing nsd8x.
2001-01-31 Kris Rehberg <Kriston@AOL.NET>
* Makefile (MODULES): nsunix, nsvhr, and nsodbc moved to the
Module Collection.
2001-01-16 Jim Davidson
* Cleaned up sloppy use of the nsServer global wherever it's used.
2001-01-04 Kris Rehberg <Kriston@AOL.NET>
* nsd/tclmisc.c: Ticket 13090. ns_striphtml crashing-bug in nsd8x
fixed.
2000-12-14 Kris Rehberg <Kriston@AOL.NET>
* tcl/http.tcl: Corrected typo _ns_ns_http_readable.
* nsd/dstring.c (Ns_DStringPrintf): Ticket 12765. Ns_DStringPrintf
uses vsnprintf instead of vsprintf with specified buffer size.
Thanks to "??".
* nsd/return.c (Ns_ConnConstructHeaders): Ticket
12764. If-Modified-Since (304) works with keepalive now. Thanks to
Jim "??".
2000-12-13 Kris Rehberg <Kriston@AOL.NET>
* include/Makefile.global: Builds with architecture-specific
optimization options. Auto-detects architecture for most
platforms. Auto-select compiler and Purify usage from command
line, e.g.:
gmake nativeme=1 (all non-free Unix)
gmake gccme=1 (some non-free Unix)
gmake PURIFY=/path/to/purify/executable (Solaris and Irix only)
* nssock/Makefile*: now installs The Right Things in The Right
Places.
* nsd/Makefile: nsd8x is the default AOLserver now (nsd symlinks
to nsd8x).
* nsd/sample-config.tcl: Added some tuning parameters for easy
reference.
2000-12-12 Kris Rehberg <Kriston@AOL.NET>
* nsvhr/nsvhr.c (UDSProxy): More type changes.
* nslog/nslog.c (Ns_ModuleInit): pointer-to-function casted.
* nscp/nscp.c (GetLine): buf changed to char *; casted AcceptProc.
2000-12-12 Jim Davidson
* nssock/sock.cpp: Fixed multiple-load problems, added sndbuf,
rcvbuf, sendwait, and recvwait options. Added configurable backlog
via Ns_SockListenEx. Fixed compile bugs for ssl. Restructured the
socket module to wait in server busy situations instead of sending
the server busy message. Also, moved the graceful close burden to
the SockThread from the connection thread.
* thread/win32.cpp: Moved WinThread allocation to DllMain,
eliminating GetWinThread function. Also, disabled thread cleanup
for final thread to avoid any TLS cleanup callbacks attempting to
invoke code in unloaded libraries like Tcl. Removed call to
NsInitThread no longer needed. Switched to rolling condition
broadcast wakeup as in the sproc code. More fixes for new Thread
context model.
* thread/tls.c: Changed NsLock API's to return 1/0 instead of
NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep things
simple.
* thread/thread.c: Changed thread enum to return Ns_Thread, not
Ns_Thread pointer which didn't make much sense. Updated "ns_info
pools" command to reflect change. Fixed bugs with Ns_ThreadEnum
and pool counters. Update of the Ns_Pool API to support more stats
gathering available via new Ns_PoolStats API. Remove Thread->etime
and NsPool API's. Moved sprintf of default thread name from
NsThreadMain to NsInitThread under protection of threads
lock. Added comment for NsInitThread. More fixes for new Thread
context model. Updated sproc.cpp code for new Thread management
and removed the wait for thread startup which shouldn't be
needed.
* thread/test.c: Cleaned up code a bit to quiet compiler. Better
test for PTHREAD_TEST. Fixed undefined var bug for sproc. Added
some comments, a native pthread test, and a recursive stack
checker.
* thread/tcl8x.c: Added Tcl_JoinThread for benefit of Tcl8.4.
* thread/sproc.cpp: Changed NsLock API's to return 1/0 instead of
NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep things
simple. Fixed some comment bugs, update thrPtr->tid after
fork. Added call the NsInitThread. Updated sproc.cpp code for new
Thread management and removed the wait for thread startup which
shouldn't be needed.
* thread/pthread.cpp: Changed NsLock API's to return 1/0 instead
of NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep things
simple. Fixed bug of not setting the tid correctly. Added call the
NsInitThread.
* thread/pool.c: Added Ns_PoolEnum to get at pool stats as with
mutexes and threads, removing the old Ns_PoolStats API's and
updating the "ns_info pools" command. Fixed bugs with
Ns_ThreadEnum and pool counters. Update of the Ns_Pool API to
support more stats gathering available via new Ns_PoolStats
API. Removed <mutex.h> for sgi which shouldn't have been
there. Removed the sbrk() code for now, was crashing SGI
(probably not thread safe). Use sbrk() on Unix instead of malloc
to avoid any malloc overhead or contention. Reduced the zippy
allocator page size to 16k from 64k.
* thread/pool.c, thread.c, sproc.cpp: Re-structured management of
the Thread context to better support threads created without
Ns_ThreadCreate (e.g., Java VM threads).
* thread/mutex.c: Changed NsLock API's to return 1/0 instead of
NS_OK/NS_TIMEOUT and more use of Ns_MasterLock to keep things
simple.
* thread/cs.c, memory.c, mutex.c, pool.c, pthread.cpp,
reentrant.c, rwlock.c, sema.c, sproc.cpp, tcl8x.c, test.c,
thread.c, win32.cpp: Restructured the thread interfaces, moving
the master lock to the platform interface code, integrating the
zippy allocator with Ns_Pool/Ns_ThreadAlloc and use of a new
simple direct allocator for all thread objects.
* win32/nsthread/nsthread.dsp: Removed master.c and oldpools.c.
* nsd/unix.c: Made ns_eval command disabled by default to avoid
using SIGUSR2.
* nsd/tclthread.c: Changed SETOBJ macro to SetObj function which
no longer sprintf's directly into interp->result.
* nsd/tclmisc.c: Added Ns_PoolEnum to get at pool stats as with
mutexes and threads, removing the old Ns_PoolStats API's and
updating the "ns_info pools" command. Changed thread enum to
return Ns_Thread, not Ns_Thread pointer which didn't make much
sense. Updated "ns_info pools" command to reflect change. Added
more info for "ns_info pools". Added "ns_info pools" command to
dump memory pool stats.
* nsd/tclinit.c: Added nsconf.quiet and nsconf.startuptimeout.
Made ns_eval command disabled by default to avoid using SIGUSR2.
Added nsConfQuiet flag to quiet down the startup messages with the
-q flag.
* nsd/sock.c: Added Ns_SockListenEx.
* nsd/serv.c: Ensured the conn thread name was set first. Added
Ns_RegisterAtReady callbacks for indicating server no longer busy.
* nsd/sched.c, nsmain.c, serv.c, sockcallback.c: Added code to
wait for conn thread, sock callback, and sched idle at startup to
help alleviate code start problems.
* nsd/nsmain.c: Shuffled initialization to ensure command line
args are read before calling any Ns API's, ensuring zippy malloc
can be set if needed.
* nsd/nsconf.c: Added nsconf.quiet and nsconf.startuptimeout.
Made ns_eval command disabled by default to avoid using SIGUSR2.
* nsd/dstring.c: Remove unused vars. Uses ns_realloc to grow
strings and maintains dstring stack in the staticSpace instead of
the *addr pointer for compatibility with Tcl dstrings.
* nsd/callbacks.c: Added Ns_RegisterAtReady callbacks for
indicating server no longer busy.
* nsd/binder.c: Added Ns_SockListenEx.
2000-12-12 Kris Rehberg <Kriston@AOL.NET>
* nsvhr/nsvhr.c (VHRProc): Matches hostnames regardless of case.
* nssock: Supports Rainbow CryptoSwift SSL accelerators
(compile-time option; requires the Swift SDK from
http://www.rainbow.com/).
* nsd/nsmain.c (Ns_Main): Changed order of some config default
initialization. Config options cleaned up a lot. Usage message
very less glib. SUNWspro dumped core on usage message due to
nsconf.argv0 quigglyness.
2000-10-20 Kris Rehberg <Kriston@AOL.NET>
*** AOLserver 3.2 RELEASED ***
2000-10-20 Jim Davidson
* win/tclWinSock.c: Fixed deadlock in sockets init code.
* nsd/nswin32.c: Fixed service install code to allow long
pathnames with spaces.
Added/use ns_pipe which set's close-on-exec like ns_sockpair.
2000-10-17 Kris Rehberg <Kriston@AOL.NET>
* nssock/sock.cpp: extra padding on Server Busy message to defeat
MSIE friendly error messages.
* nsd/nsconf.h: All configuration option defaults have been moved
to nsconf.h as #defines.
* Makefile (install): Tcl library for nsd8x is now installed into
$(PREFIX)/lib/tcl8.3.
* tcl/http.tcl (ns_httpopen): Host:port is now sent to remote host
if != 80. Suggested by Jerry Asher.
* tcl/fastpath.tcl (_ns_dirlist): All kinds of Win32 pathnames
should now be working. Thanks to Eric Klein.
* nsd/return.c (Ns_ConnReturnNotice): New options "errorminsize",
to pad error messages to defeat MSIE friendly errors (fix
suggested by ArsDigita) and "noticedetail" to return more detailed
information on notice pages.
* nslog/nslog.c: suppressquery option added to suppress logging of
query data.
* nslog/nslog.c: LogExtendedHEaders option added. Contributed by
ArsDigita.
* nsd/tclfile.c: Input string to mktemp is copied, because mktemp
edits the string in-place and that's generally a bad thing to do
with argv's. Contributed by ArsDigita.
* nsd/tclnsshare.cpp (ShareTraceProc): Patch to tclnsshare.cpp to
avoid race conditions if the shared value is a list. Contributed
by ArsDigita.
* tcl/http.tcl (ns_httpopen): CRLF now returned in ns_httpopen.
Contributed by ArsDigita.
* tcl8.3.2/generic/tclCmdIL.c: Nonsense case of lsorting a list
with length <= 0 caused a memory leak. Fixed. Contributed by
ArsDigita.
* nsd/adpfancy.c: We now use the Arsdigita version of adpfancy.
Contributed by ArsDigita.
* nsd/adp.c: Sundry ArsDigita changes.
2000-10-16 Kris Rehberg <Kriston@AOL.NET>
* tcl/init.tcl: Initialize errorCode and errorInfo like tclsh
does. From ArsDigita.
* nsd/nsd.h, nsd/tclcmds.c, nsd/tclvar.c: nsv_names Tcl command
lists names of nsv's in memory.
* tcl8.3.2: The complete Tcl 8.x distributions are now included.
They aren't installed with AOLserver's "gmake install", but you
can install them manually if you want to use them for the i18n
encodings and stuff like that. It will install into the
"lib/tcl8.3" directory of the binary distribution with AOLserver
3.3 and later.
* nsd/nsmain.c (Ns_Main): Had to move Ns_ThreadSetName below the
stdin/stdout/stderr reassignment to fix a fd problem with running
nsd on Irix in "installed" or "daemon" mode that would prevent the
server from starting up. Sigh.
(Ns_Main): Took out little note about -k|-K being deprecated.
2000-10-13 Kris Rehberg <Kriston@AOL.NET>
* nsd/nsmain.c (Ns_Main): gid of the specified user is set even if
it's not specified.
(UsageError): -K and -k give a "deprecated" warning.
(Ns_Main): -f gives a "deprecated" warning.
* nsd/binder.c (PreBind): Didn't really tell us if it was
successful at pre-binding. Helpful to know if you're wondering
what happened to that port you wanted to pre-bind.
(Binder): backlog variables (2) initialized to nsconf.backlog.
* nssock/sock.cpp, nsd/return.c: Made an attempt at standardizing
the error codes and error page content.
2000-10-13 Jim Davidson
* sproc.cpp: Fixed Wakeup() error message and update child's
sproc pid after fork.
* nsd/random.c: Put back log message when generating seeds.
* nsd/nsconf.c: Fixed memory overwrite bug in stats and increased
the default buffer value.
* nsd/keepalive.c: Fixed array overwrite with maxkeep=0 bug.
Contributed by ArsDigita.
* nsd/tclkeylist.c: A more modern version added that's compatible
with Tcl 8.3.2 (nsd8x).
* nsd/stamp.c: Forces the build date reported by AOLserver to be
absolutely the last possible moment before the link step happens,
not just the last time nsmain.c was built.
* nsd/binder.c: New option "-b" to prebind ports as root (but not
listen on them). This allows AOLserver to start up on MacOS X on
ports 80 and 443 like this: "nsd ..blah.. -b 10.0.0.1:80".
* nssock/: Building nsssl is much less of a debacle and doesn't
rebuild itself three times anymore.
* various: fork() calls in all kinds of code were changed to use
ns_fork. ns_fork now lives in the thread library (thread/
directory).
* tcl8.3.2/generic/tclIO.c: Fixed memory leak that leaks around
112 bytes each time a file descriptor is closed. Thanks to Rob
Mayoff for finding this and proposing a solution.
2000-10-09 Kris Rehberg <Kriston@AOL.NET>
* sample-config.tcl: nsd.tcl is now sample-config.tcl so that
existing users can look at the new reference configuration.
* nsd/nsmain.c (Ns_InfoNameOfExecutable): new function just
returns nsconf.nsd which is determined elsewhere.
* nscp/nscp.c (Login): Tells you lots of harmless info about the
machine once you log in. Also, nscp does not run unless
configuration is explicitly set
* nsd/nsmain.c: Some typo or other.
* General: Files were re-arranged and some were renamed. The
sample SSL key/cert files are sample-certfile, sample-keyfile.
The nsd.tcl is now called sample-config.tcl (so that existing
installations always have a current reference copy of the
configuration). Other minor changes.
* tests/: Moved from its hiding place in scripts/test. Install
them with "gmake install-tests".
* nsd/tclxkeylist.c, nsd/tclcmds.c, nsd/Makefile: Re-added TclX
keyl* commands that were in AOLserver 2.x. These are inferior to
ns_set which is why they were left out in the first place.
2000-10-04 Jim Davidson
* binder.c: Set close-on-exec on received fd from binder.
* sock.c: Removed cthread errno API's, Mac OS X now has
thread-safe errno.
* nsd/nsmain.c, include/Makefile.global, nsd/nsthread.h,
nspd/main.c, nsunix/nsunix.c, nsvhr/nsvhr.c, thread/Makefile,
thread/osthread, thread/reentrant.c, thread/signal.c: Updates for
Mac OS X. Use MACOSX instead of APPLE; use HAVE_BSDSETPGRP,
HAVE_CMMSG, use pthreads instead of cthreads.
* nssock/sock.c: Removed setting bufsize to uninitialized value on
ssl.
* include/ns.h: Removed Ns_CacheTimedGetValue which was an odd
interface not used anywhere.
* nsd/nsd.h: Update to version 3.11.
* tcl/namespace.tcl: Added namespace export to init script.
* thread/pthread.cpp: Stopped using pthread_once as it appears to
require a lock.
2000-10-04 Kris Rehberg <Kriston@AOL.NET>
* win32/nsssl/nsssl.dsp: nsssl project for win32.
* win32/aolserver.dsw: main installation keeps DLL's as DLL's now.
* scripts/nsd.tcl: shared library extension is now
platform-dependent
* nssock/ssltcl.c: Changed name of ReadFile adn WriteFile to avoid
Win32 naming conflicts.
2000-09-28 Kris Rehberg <Kriston@AOL.NET>
* scripts/tests/nstelemetry.adp: added "Expires: now" header to
ensure it gets run each time it's visitted.
* nsd/serv.c (NsConnArgProc): Race condition when threads exit
while [ns_info threads] is run; arg can be NULL. Seen mostly by
people who regularly visit nstelemetry.adp.
(AppendConn): same thing but with connPtr. This may be a losing
battle. It appears to work on a busy Irix server, so I'm
declaring victory for now.
2000-09-28 Jim Davidson
* nssock/sock.c: Fixed bufferred read code in SockRead, resulting
in a big performance boost and system load reduction. Special
thanks to Zachary Girouard.
2000-09-05 Kris Rehberg <Kriston@AOL.NET>
*** AOLserver 3.1 Released ***
2000-09-05 (various: Jerry Asher, Jim Davidson, "Dossy," Curtis Galloway,
Scott S. Goodwin, Rob Mayoff, Kris Rehberg <Kriston@AOL.NET>)
* thread/win32.cpp: Sets thread stack size as on other platforms.
* thread/thread.c: NULL out thread arg at exit to avoid
Ns_ThreadEnum checking arg info for possibly deallocated context
as seen in ns_info threads. Also, moved read of firstPtr in
Ns_ThreadEnum inside lock. Added Ns_ThreadCreate2 in thread.c
needed for upgrade to Tcl 8.3.1 in tcl8x.c
* thread/pthread.cpp: ETIME bug work around not causes wakeup in
Ns_CondWait and Ns_CondTimeWait instead of waiting again. This is
more conservative and should avoid problems some have had with
threads missing wakeup.
* thread/pool.c: Added a simple 1-byte range check to -z
allocator.
* thread/Makefile: Added dependency for osthread.o to Makefile.
* tcl/namespace.tcl: Added namespace export to init script.
* nsvhr/nsvhr.c: Switched to Ns_WriteConn in TimedSockDump to
ensure all data was sent.
* nssock(nsssl): SSL module includes a fake 40-bit/512-bit
export-grade SSL keyfile.pem and certfile.pem for immediate use on
installation. Adjusted for use with BSAFE 4 and 5.
* nspd: Library now installed to binary distribution.
* nsd/tclsock.c: Fixed crash bug in error message in ns_socknread.
* nsd/tclcmds.c: Added ns_adp_registertag command as documented.
* nsd/serv.c: Added missing break for unauthorized case in
ConnRun.
* nsd/random.c: Fixed deadlock between Ns_DRand/Ns_GenSeeds.
* nsd/nsmain.c: Fixed some message formatting problems.
* nsd/mimetypes.c: Added .png type, "image/png".
* nsd/dbtcl.c: Removed unused variables in GetCsvCmd. Use a
dstring to create the column list instead of incrementally setting
the output variable with Tcl_SetVar. This was necessary to avoid
conflicting definitions of the needed TCL_ flags between 7.6 and
8.x.
* nsd/dbinit.c: MOdified current per-thread handle count to use a
single TLS slot instead of a slot per pool.
* nsd/tclinit.c,adp.c,conn.c: The use of thread-local storage
(Tls) is now self-initializing in the conn, ADP, Tcl, etc. This
allows ns_conn commands to be used outside a connection thread as
well as other uses of Tls where it may not be ready for use.
* nscp/nscp.c: Password non-echo code confuses Win32 and some free
Unix telnet clients so it has been disabled by default for now,
though it can be enabled by setting "echopassword" in the nscp
module section of nsd.tcl.
2000-08-21 Kris Rehberg <Kriston@AOL.NET>
* nscp/nscp.c: Makes some attempt to recognize and handle telnet
IAC codes like CTRL-C and CTRL-D to force a logout. This
implementation of the telnet protocol is dirt-cheap, so only
standard Unix telnet is supported. On Win32, IAC handling is
completely disabled because the client is too chatty with its IAC
codes.
2000-08-20 Kris Rehberg <Kriston@AOL.NET>
* nsftp, nspostgres, nssolid, nssybpd moved to $TOP level.
2000-08-17 Jim Davidson
* nsd/dbtcl: Removed unused variables in GetCsvCmd.
* nsd/adp.c: Fixed bug of not truncating output buffer when an
error was thrown during an ns_adp_parse. Fix suggested by Rob
Mayoff.
* tcl7.6 and tcl8.2.3: Switched to blocking Tcl_WaitPid to avoid
zombies as suggested by Rob Mayoff.
* thread: NULL out thread arg at exit to avoid Ns_ThreadEnum
checking arg info for possibly deallocated context as seen in
ns_info threads. Also, moved read of firstPtr in Ns_ThreadEnum
inside lock.
2000-08-17 Kris Rehberg <Kriston@AOL.NET>
* nssock/sock.c (SockThread): warning sent to log when Server Busy
is returned.
* All the Makefiles should be in line with each other. Typing
"gmake", "gmake install" and "gmake clean" should work in any
directory. NSHOME is paid attention to by all Makefiles.
* nsd: Ns_Log and Ns_Fatal statements are hopefully more
standardized and more useful to admins and developers.
* Irix now builds as -o32 using the native compiler by default.
See Makefile.global on how to change.
2000-08-15 Kris Rehberg <Kriston@AOL.NET>
* include/Makefile.global (INSTLOG): should have pointed to
$(INST)/lib, not $(INST)/modules/lib.
* Makefile: nsunix resurrected. All modules are built. If a
module is missing a library, it is not built, but it won't stop
the AOLserver build process (no error is thrown). The build will
continue with the next module.
* nsftp: guesses if you have TCP_WRAPPERS available.
* nsext: Ten guesses why $(NSHOME)/include/nsextmsg.h was
duplicated here.
* nssybpd: Hopefully, the log statements will be easier to
understand by both admins and developers. It's still messy since
it uses syslog. Makefile redone to use standard AOLserver rules.
RPATH is used a little more intelligently. Removed files that had
no business living there.
* include/Makefile.global: Took stab at RPATH support on Solaris
to perhaps remove the need for LD_LIBRARY_PATH on an
intelligenly-administered system. New rule for libnspd.a.
2000-08-14 Kris Rehberg <Kriston@AOL.NET>
* Makefile: nsvhr has been resurrected and enjoys our full
support.
* nsexample/Makefile: The include at the bottom wasn't using
$(NSHOME).
2000-08-14 Jim Davidson
* Tcl 8.x library upgraded to tcl8.3.2.
* thread/pool.c: A spiffy range-checker added to the Zippy (-z)
memory allocator.
2000-08-11 Kris Rehberg <Kriston@AOL.NET>
* nsvhr/nsvhr.c: Always add "Connection: close" to the request
line to satisfy HTTP 1.1 RFC -- this would break MSIE in HTTP 1.1
mode. HTTP_EOL of "\r\n" used on all request lines for stupid web
servers on the other end. Protocol "tcp" added as synonym of
"http" for old-time Unix heads. Lots of folks lended a hand on
this one -- Satyam Priyadarshy, Jerry Asher, Kriston Rehberg, and
special thanks to Wanda G. at AOL for adding a CNAME in DNS so
quickly.
2000-08-09 Kris Rehberg <Kriston@AOL.NET>
* nsd/serv.c: A whole lot less chatty about conns starting and
exiting. If you want to see them, turn on the Debug flag.
* doc/*: lots of updates. Title page extremely simplified. SSL
docs updated. Release notes updated. NSV docs corrected (thanks
to Todd Levy.
2000-08-09 Jim Davidson
* tcl7.6/generic/tclFHandle.c: Removed needed fileTable which
could result in crashes when fd's where reused quickly [fixes a
rare multiple-exec crashing bug in nsd76 --kris].
* thread/tcl8x.c: Added a wrapper startup for Tcl_CreateThread for
the benefit of Win32.
* nsd/log.c: Removed severityRank array.
* nsd/tclmisc.c: Fixed bug with ns_info pid. [I can't code --kris]
* nsd: keepalive.c,nsmain.c,sched.c,serv.c: Re-ordered shutdowns
to ensure connection threads are stopped before other shutdowns
begin (e.g., sched, sockcallback).
* tcl8.3.1 replaces tcl8.3.0. README.AOLSERVER added to tcl8.3.1
directory. Original copies of changed are named *.orig.
* include/Makefile.global: Build environment now uses gcc -shared
-nostartfiles as the default LDSO.
* nsthread/thread.c: Added Ns_ThreadCreate2 with extra flags
argument used by Tcl_CreateThread to create a detached thread.
2000-08-06 Scott S. Goodwin
* nsd/log.c: Segmentation fault was occuring when writing to the
log file because file pointer was being assigned to incorrectly -
it wasn't NULL and it wasn't a valid address within processes
memory. Fixed.
2000-08-06 Scott S. Goodwin
* nssock: You can now compile with BSAFE versions 4 and 5. You'll
need to specify the path to your BSAFE libaries and the BSAFE
version in the nssock/Makefile before compiling. If you don't have
BSAFE and want to compile without SSL at all, edit the toplevel
Makefile and take out all the "SSL=1" text. The files changed were
nssock/Makefile and nssock/t_stdlib.c.
2000-08-02 Kris Rehberg <Kriston@AOL.NET>
* Build process is a little more rule-oriented. The cleaning
rules "distclean" and "clobber" were removed. The Tcl libraries
are always distcleaned when "gmake clean" is invoked. Rules that
can be used as dependencies were made for libnsthread and the Tcl
libraries -- their names are "libnsthread," "libtcl76," and
"libtcl8x," respectively. PREFIX is now used as the installation
directory (along with INST), so the more familiar "gmake install
PREFIX=/usr/local/aolserver" will work. Additionally, gmaking in
a subdirectory with dependencies now works.
* nsd/log.c: The sourge of modlog has been removed. All code
included with AOLserver that used Ns_ModLog now doesn't. Many log
statements are now hopefully more standardized. This will be a
continuing improvement over the next several updates. I would
like to use gcc's __FUNCTION__ macro but it doesn't work on native
compilers, but we may start using __LINE__ and __FILE__ instead or
replace Ns_Log with a smart macro that takes care of all this
stuff for us.
* nsd/tclmisc.c (NsTclInfoCmd): ns_info pid added to return the
process id.
2000-08-01 Kris Rehberg <Kriston@AOL.NET>
* nsd/adp.c (Ns_AdpRequest): The enableexpire option was putting
an Expires header even if it already existed.
* nsd/return.c (Ns_ConnReturnNotice): Yikes, /face should have
been /font. No more fonts, colors, etc, on default notice pages.
* nsd/tclsock.c (NsTclSockOpenCmd): Removed spurious Ns_Log Notice
from ns_sockopen.
* tcl/form.tcl (ns_getform): MSIE presents the wrong stuff to the
server when a multipart/formdata POST is redirected. Workaround
contributed by Joseph Bank.
* tcl/fastpath.tcl (_ns_dirlist): base href removed -- links are
now fully-qualified.
* Makefile (install): include and lib dirs are now included in
binary distribution.
* tcl/http.tcl (_ns_http_gets): \n replaced by \r in all but
_ns_http_gets so that arbitrary headers get set correctly.
* tcl7.6/generic/tclPosixStr.c (Tcl_SignalMsg): Patch to Tcl 7.6
for Red Hat on SPARC architectures. Contributed by Mike Chan.
2000-07-13 Kris Rehberg <Kriston@AOL.NET>
* scripts/nsd.tcl: nssslmodule names the nsssl/nsssle binary's
filename. nscp_port tells nscp what port to listen.
* nssock: nssock.c renamed sock.c, SSL support has been merged
back with nssock so that both nsssl and nssock use identical
socket code.
* nsssl2: directory removed; nsssl is in the nssock directory now.
2000-05-09 Kris Rehberg <Kriston@AOL.NET>
* Re-added doc directory which has had the online docs removed.
2000-05-02 Kris Rehberg <Kriston@AOL.NET>
* Makefile, include/Makefile.global, include/Makefile.module,
nsexample/Makefile: Now uses NSHOME variable to locate AOLserver.
NSHOME is automatically figured out in the top-level Makefile and
all the lower Makefiles still use relative directory paths. The
intention of NSHOME is for modules that do NOT live in the
AOLserver source directory tree. The nsexample/Makefile explains
how this works.
* nsftp module added. Contributed by Eric O'Laughlen.
