ioFTPD v7.3.3 Released (Beta)
Changed to dynamic runtime linking just to see if that affects the lockup bug in any way.
If you get "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." then you need to install the VS2008 SP1 Runtime from MS which is a free download.
Assuming the lockup bug isn't fix this version may be able to detect it and suicide. This is useful when run as a service since it can be configured to auto restart.
Restored nxMyDB compatibility which was broken in v7.1 but wasn't reported. I also fixed a bug that looks like it was causing all the crashes pion sent me, but only occurs when using nxMyDB.
Latest Version:

ChangeLog
Code:
v7.3.0 Release Notes:
IMPORTANT: The way ioFTPD.exe is linked has changed. If you get the following
popup error dialog: "This application has failed to start because
the application configuration is incorrect. Reinstalling the
application may fix this problem." Then you need to install the
Visual Studio 2008 SP1 runtime from MS, see #4 below!
1) Files in \System:
Changed : ioFTPD.[exe,pdb] - Version 7.3.0.0.
Changed : tcl85t.[dll,pdb] - Version 8.5.2.8 (dynamic CRT, dated 3/24/2010)
2) Files in \:
Deleted : README
Added : README.txt
3) Directories in \lib:
Replace entire reg1.2 directory.
Replace entire dde1.3 directory.
*** New Features
4) The TCL dlls and ioFTPD.exe are now linked against the VS2008 SP1 dynamic
CRT/runtime dlls. This means that they need to be installed on your
computer because they are not distributed via a simple file you can drop
into the directory and ioFTPD doesn't have a fancy installer... I think
Win7 and perhaps Vista have these installed by default, but XP I know does
not, although it is possible that another piece of software installed these
for you are part of their setup.
If you run ioFTPD.exe and see the follow message:
This application has failed to start because the application
configuration is incorrect. Reinstalling the application may fix this
problem.
then you don't have them installed. Goto:
http://www.microsoft.com/downloads/details.aspx?familyid=A5C84275-3B97-4AB7-A40D-3802B2AF5FC2&displaylang=en
to download vcredist_x86.exe for VS2008 SP1 which is a free download.
You may also see entries in the system event log in the System category
if running ioFTPD as a service or if you somehow aren't seeing the error
message popup. They are under the name 'SideBySide' and look like:
Dependent Assembly Microsoft.VC90.CRT could not be found and Last Error
was The referenced assembly is not installed on your system.
Resolve Partial Assembly failed for Microsoft.VC90.CRT. Reference error
message: The referenced assembly is not installed on your system.
Generate Activation Context failed for c:\ioFTPD\system\ioFTPD.exe...
5) Added a new thread that just updates a variable with the current time every
10 seconds after having called a simple function that internally uses the
loader lock. When the window's internal loader lock gets stuck this should
fail to return and within a minute the process will detect this in another
thread, output a log entry that looks like:
"System detected loader lock compromised! Terminating!"
and then try to terminate the process immediately / ungracefully.
6) When run as a service ioFTPD will now return an error code to the service
control manager if the server was unable to start because of an error
during initialization. This should result in a windows system event being
logged which can help alert you to the problem. The Invalid Function
error (#1) is used if the server doesn't have a more appropriate error
code to return. When run interactively the server will continue to just
pop up a dialog box with the error.
7) To restore compatibility with nxMyDB the exported functions Config_Get,
Config_Get_Int, Config_Get_Bool, Config_Get_Path have the old signature
and only work against the server's configuration file, usually ioFTPD.ini.
Also, I've recorded the list of functions nxMyDB looks up and will try to
keep them the same in the future.
*** Bug Fixes:
8) Fixed a bug where the server would crash if a valid user was logging in
and the userfile lock was unable to be acquired, or if in the process of
being acquired and the user was kicked (via site command or !login). The
later is nearly impossible as local locking cannot fail and is very quick,
however the former may be common when using 3rd party user modules such
as nxMyDB and the DB is offline / lagged.
9) Fixed a bug with hostnames forwarded via the IDNT commmand from BNCs.
If the BNC forwarded the IP address as the hostname the server would treat
it as a reverse resolved hostname and apply the host obscuring rule to it.
Now if the IDNT command sees the host parameter is all numbers it converts
it to an IP address and if it matches the actual IP address portion of the
the IDNT argument it doesn't set the hostname. That emulates the regular
meaning of the hostname field where it is only set upon successful reverse
resolving of the IP address, thus when the server needs to display a
hostname it will default to using the IP address in numeric form and apply
the IP obscuring rule to the result.

I suppose its a bit late, but I recently added support for the new (now old ) ConfigReader API to nxMyDB (yesterday in fact).

neoxed: Glad to see you around I'll leave the "original" routines in place until the next server change or you get ready for the next release of nxMyDB. Just give me a heads up and I'll switch to the new routines so people can upgrade then.
That link looks like you put the sources up, I didn't think they were there so I couldn't fix it myself. Thanks. In the future that will make it easier if I break something and there isn't an easy way around it.

Oh, I forgot to mention. If you find you need/want info from the server, an easier way to do something, etc please ask. I'm happy to encourage anyone interested in coding scripts/addons!

Silly. Can you check the Error.log and see if you see the "System detected loader lock compromised! Terminating!" message? I'm assuming you saw that because you said it detected it. On the other hand it appears that trying to kill oneself via TerminateProcess while the loader lock is held and there are outstanding I/O requests doesn't work... I'll have to see about better ways to force an exit, perhaps even using another process to do it...

I learned a thing or two about how to get the thread ID that holds a lock and using that examined some old minidumps of the lockup bug I had from years ago and discovered something weird. The thread holding the loader lock isn't an ioFTPD created thread (they are all accounted for) and it isn't in the minidump which I presume means it exited without releasing the lock and without calling the ioFTPD CrashLog code (the minidumps were created manually).
Since it isn't an ioFTPD thread it's harder to debug since I'm not sure how I would try to even catch it's creation/exiting since the normal uncaught exception handler that should be called clearly wasn't. I'm guessing it's a winsock thread of some sort, but for the moment it appears to make the most sense to switch over to openSSL as soon as possible to try to remove all that MS encryption library crap that might be causing problems and we don't want to use long term anyway...
P.S. Silly, others. The windbg !locks command is useful only against full minidumps. Tinydump's simply don't include the memory regions that extension scans to enumerate critical sections. So, I'll need the full size large dumps rar'd or zip'd please.
The only other thing I might look into is knowing the lockup bug is caused by a thread that exited without releasing the lock, I might just try to find a way to force the freeing of the lock somehow and then suicide...

Two new issues.
monk-: Your dumps indicate I fixed one crash issue with nxMyDB only to expose a related one later in the cleanup function. It's easy to fix, and I'll do so in a bit along with looking into updating the open/lock module functions to print errors to the logfile so we can get a handle on what is failing where. Does nxMyDB have it's own error log that we could look at? This bug only affects sites using a shared user module.
Silly: I learned from your dump that the server was preloading directories during a server shutdown and didn't finish in time so it crashed when the thread didn't end. I'll add some code to test for graceful shutdowns and exit it cleanly. This doesn't affect anything since the FTP was shutting down but may create dumpfiles if preloading takes more than a minute or so.

Code:
[19:49:22] [L] SITE SYMLINK /DIR/Test/ | Test-link
[19:49:24] [L] Connection lost: TEST (ioFTPD)
ioFTPD crashes.
Also a zipscript (exe) that works fine in v6.9.3 and creates symlinks that work. In v7.3.0 (haven't tested older v7.x) the symlinks won't resolve, but when checking the virtual target of the symlink it seems ok:
Code:
CWD (incomplete)-Dirname
550 (incomplete)-Dirname: No such file or directory.
SITE CHATTR +l "(incomplete)-Dirname"
200-CHATTR: "/Some_section/Dirname"
Also, that same zipscript (again, that works just fine in v6.9.3) says all is ok but no files remain after upload. It creates the missing-files and progress bar and that non-working symlink but all uploaded files disappear. How much of the EXEC module has changed between given versions and what has to be done to make the script work again?
