*** Incompatible changes:
7) Removed "SITE CHANGE <who> NON-LEECH" as you can do the same thing with
"SITE CHANGE :=0 RATIO" and it's far more versatile.
*** New Features
8) New site command (site perms [ -<user> ] [ <item> ]). Displays
permission information for you, or another user, about the indicated
item with the default being the current working directory if no argument
supplied. If processing a directory then also display the default rules
for items in the directory. This is actually a REALLY nice command!
It shows why you can or can't upload, delete, rename, etc. Try running
it from '/' so you can see all the rules if you vary action permissions
by path. See 'SITE HELP PERMS' for more details, but make sure you do
it from a VM flagged account as both the help information displayed and
the command results vary by the flags of the calling user.
9) New site command (site sectionnums). For each section number defined
in the configuration file show its name and if it shares credits and/or
ratio settings with another section. Then display a list of paths and
the section number to use for them.
10) New site command (site uptime). Simply displays the server and FTP
uptimes.
11) New site command (site knock). If port knocking is enabled display the
current port connection sequence to trigger a "knock" else let the user
know the feature is disabled.
12) New list argument (LIST -U). Replaces the group field with the average
upload speed in KB/s or "-" if that information is unavailable as for
all existing files prior to v7.2 and all non-file objects such as
directories and symbolic links.
13) New site change command (SITE CHANGE <user-glob> DNSPEED <speed>). This
sets the maximum download speed for matching users to <speed> much like
the SPEEDLIMIT <speed> change command would. It is provided for
symmetry with UPSPEED and because it's easier to remember.
14) New site change command (SITE CHANGE <user-glob> UPSPEED <speed>). This
sets the maximum upload speed for matching users to <speed>. This is
useful when modifying more than one user at a time because you don't
need to also set the DNSPEED limit like you would if you used the
CHANGE SPEEDLIMIT command.
15) New ioFTPD.ini options (TimeStamp and TimeStampOwn actions under [VFS]).
You can now control who can modify timestamps of files on the server by
path with these 2 new actions. Previously if the file was writable by
the user they could set the timestamp provided the MDTM command was
accessible to them. Since MTDM also allows you to read the timestamp
disabling it was not a good option and it didn't allow for doing so
based upon the path.
16) New ioFTPD.ini option (Enable_TimeStamp_On_Last_Upload under [Ftp]). The
new TimeStamp and TimeStampOwn actions cover most cases, however you may
wish to allow users to modify the timestamp of the last file uploaded
even if those checks fail. The main reason this is useful is when
zipscripts remove +w access from an uploaded file that was verified and/or
modify the owner of the file. In both those cases the normal checks would
fail. It's also somewhat useful if the zipscript doesn't modify anything
but you don't wish the user to change the timestamp later on, but don't
mind them doing it right after it is uploaded. There isn't any other way
to express that. The default is FALSE which disallows the exception.
17) Modified site command (SITE CHANGE <group> GROUPDESCRIPTION <what>). If
<what> is "NONE" then the group will have an empty description. Since
all SITE CHANGE commands require an argument it previously wasn't
possible to completely remove the description once set.
18) Modified site command (SITE GROUPS [ -ALL ]). The site groups command
has been changed to include the idea of "hidden" groups which should not
be displayed in the listing by default. This supports the practice of
changing the group ownership of files and directories to convey
information instead of ownership. An example of this would be ioNiNJA's
MP3 genre labeling via group owner. A group is considered hidden if it
has no users and a description of "-". Use the -all argument to see
hidden groups in the listing as well.
This command is also changed for GroupAdmins. They will only see GID #1
('NoGroup') and groups which they can admin.
19) The SITE WHO and SITE STAT (with LIMIT option) will now only accept
user, username*?, and =group style arguments for non SiteOp/Masters.
Even the =group option is limited to groups the caller is a member of.
This is to prevent leaking group, ratio, and flag information via the
powerful globbing mechanism. Jury out on if GroupAdmins should be
exempt here as well.
20) New user-glob feature (=.<group>). The '.' means matches users whose
primary group is <group>.
21) New user-glob feature (:<group> and :.<group>). These match users who
have group as an adminGroup or as their primary adminGroup respectively.
22) New user-glob feature ([] and [^]). You can now use character group or
range matching in addition to '*' and '?'. The ^ prefix means to match
any single character not specified.
23) Modified the behavior of 'SITE MYINFO' to no longer show section name
and information if all paths in the section are hidden to the user.
24) New .ini feature for [Virtual_Dirs]. You can now make hidden virtual
directories to some users. The Virtual dir definition now looks like:
<path> = [ "<perm>" ] TCL <script>
The new optional <perm> argument is a flag-style permission string that
acts like the hidden/private directory feature and controls who can see
the dir.
25) The resolver flag to allow loading information from virtual directories
has been added to a number of commands. This should allow directories
and files to be looked up from the last cached directory, and if that
fails then it will call the script expecting a ||RESOLVED|| reply. The
ability to operate on completely "virtual" items that don't exist in the
filesystem is being looked into for a future release.
The basic functions of downloading (RETR), uploading (STOR, APPE),
renaming (RNFR/RNTO), deleting (DELE or RMD), and creating (MKD) files
and directories will all now attempt to resolve via the virtual directory
script. In addition user specified home directories (other than "/")
can be virtual and MDTM, SIZE, and XCRC should work. The following
site commands were also modified: chattr, chmod, chown, size, free, perms,
and symlink. However any feature that requires more than a single
file, directory, or symlink being resolved will fail. Thus the wildcard
and -R features of chmod and chown will not function and the size command
will not correctly handle merged/raided directories.
26) Modified ioFTPD.ini option (Feature_Suppression under Devices). You
should now use "LIST -" and "STAT -" instead of the full string since the
actual arguments displayed after the "-" depends upon the user's flags.
27) New message cookie (%[$cwd]). Returns the user's current symbolic path
or the users fully resolved path if symbolic paths aren't being kept.
Also added this to ioftpd.env so it's exported to child processes run
via the EXEC command.
28) New message cookie (%[$UpTime]). Returns the number of seconds since the
FTP server started. You can then feed this into the $[Duration] cookie
for a human readable time. New default text/ftp/Welcome uses this.
29) New message cookie (%[$SysUpTime]). Returns the number of seconds the
computer has been running (doesn't count hibernation/sleep time). You
can use $[Duration] to get a human readable time.
30) Modified super cookie (%[Duration]). The cookie displays elapsed time
between now and a time in the past, or 2 arbitrary times, in human
readable form (y, w, d, h, m, s). It now takes 1 fixed and 8 optional
arguments to control how it's output should look.
*Arg1: Time1 (0 implies Time2 is duration)
Arg2: Time2 (0 implies now)
Arg3: Extra text to append
Arg4: Precision, last field to show, default s
Arg5: Precision, first field to show, default y
Arg6: Style: 0="y", 1=" year", 2=" years" if >1, default 0
Arg7: Field separator, default " "
Arg8: 0 = hide zero fields after the first non-zero field displayed,
1 = show, default 0
Arg9: min numeric field width, and adds an extra space if style 2
for non-multiple entries, default 0
*** iTCL Changes:
31) The TCL virtual directory event now has 2 additional arguments and looks
like: "<path>" "<glob>" "<old-glob>" <exists> <cmd>
<exists> : Either 0 or 1 depending upon whether the resolver requires
that the item exist in the filesystem.
<cmd> : The name of the FTP command that caused the resolver to be
called or "-" if unknown. Useful for deciding what to return.
Please see the v7.0 release below for a description of the other args.
32) New iTCL command ([ioUptime]). Returns the uptime for the OS and the
FTP in seconds.
33) New iTCL command ([ioTransferStats]). This command returns the size and
duration (in milliseconds) of the last file transfer.
34) Modified iTCL command ([ioVirtual AddDir|AddFile]). The <Link> argument
is now optional to AddDir and AddFile. There is now no difference between
the long form of AddSubDir and AddDir when no <link> target is specified.
AddDir <Size> <ModTime> <AltTime> <User> <Group> <Mode> <Name> [<Link>]
AddFile <Size> <ModTime> <AltTime> <User> <Group> <Mode> <Name> [<Link>]
35) Modified TCL command ([resolve list <path>]). The 'uptime' field has
been added to the list of information returned about each entry. Each
element of the list now looks like:
Each element of the list looks like:
{ name type uid user gid group size mode attributes
win-last-time unix-last-time win-alt-time unix-alt-time
subdir-count {realpath link ...}
{chattr-0 chattr-1 chattr-2 chattr-3} uptime }
'type' field is: 'd' (dir), 'f' (file), or 'l' (ioFTPD link)
'win*' times are the actual FILETIMEs.
'unix*' times are in time_t or unix style times (seconds)
'realpath' and 'link' come in pairs where 'realpath' is the full path
to the real directory and link {} if a regular directory or in the case
of an NTFS junction the fully resolved target directory path. This
sublist will be {} for virtual dirs or mountpoints.
The first 4 "reserved" chattr fields are returned in order as well:
Private, ioFTPD Symlink, <reserved>, <reserved>.
'uptime' is number of milliseconds file took to be uploaded.
36) Fixed a bug in [resolve list] where the 4 [chattr] settings returned
were not actually the first 4 settings as intended.
*** Bug Fixes:
37) Fixed a bug with implicit SSL connections (Explicit_Encryption = False)
that was causing the server to ignore all client commands after the SSL
negotiation.
38) Fixed a bug where just the first 12 characters of the user and group
were being printed in long directory listings. This is obviously
important when dealing with client macros that operate on the owner
or group of a file or directory and extract this info from the directory
listing. This also allows for correctly displaying long fields via some
list '-' options such as the private directory setting in the group field.
39) Fixed a bug when multiple custom commands in [FTP_Custom_Commands] were
defined under the same name. Previously it would print the response code
after the each entry which would mess up FTP client response parsing. It
now stops and returns an error after the first failed entry, and prints
success only when all entries returned successfully.
40) Fixed a bug with the tcl function [resolve] when using the 'target',
'vfs', or 'symbolic' options that resulted in errors being generated to
'Error.log' if you had disabled keeping symbolic links in the path via
the .ini file and didn't specify a <cwd> argument when called. In this
situation the user's current symbolic path wasn't being updated by the
server because it would always be equal to the non-symbolic path but the
resolver was explicitly told it should operate on the symbolic path and
thus would print an error before going ahead and performing the operation
on the non-symbolic path. Thus it would always function correctly, but
since this is an allowable scenario no error should be generated. The fix
was not uniform however. The 'target' and 'vfs' options no longer pass
the flag to operate on the symbolic path to the resolver, while the
'symbolic' option makes sure the symbolic path is set to the non-symbolic
path (which is always true since the option for this was disabled in the
.ini file) before calling the resolver to update it further.
41) Fixed a bug where the the 'G' flag for group admins was testing the
target's account instead of the user's account before checking for
groupadmin rights.
42) Fixed bugs in RNFR/RNTO, DELE, MKD, RMD, STOR, 'site symlink', and 'site
chmod' where the parent directory to test for +w was computed from the
real path instead of the virtual path which can differ when dealing with
merged/raided directories.
43) Fixed a bug where resumed transfers were not being counted as uploads
when testing user limits.
44) Fixed a bug where the MDTM would complain if the first of more than one
argument doesn't look like a date, it now just assumes the whole line is
a filename if it doesn't look like a date. This handles spaces in
filenames much better when client's don't enclose the filename to modify
inside double quotes.
45) Fixed a bug where purged users where not increasing the group slot
counter for the primary group of the deleted user.
46) Site change credits no longer defaults to the creditsection of the
current path and instead defaults to section 0 all the time.
*** Internal non-visible changes:
47) Section information is now kept in a parsed form to speed lookups.
48) Exported function FindFirstUser changed.
