SQUISH 1.11 REVISION NOTES -- SUMMARY OF CHANGES FROM 1.10
The following functional changes were made in Squish 1.11. (See
later in the file for a list of changes between Squish 1.10 and
Squish 1.01.)
* Squish now comes with SQFIX32.EXE and SQFIX32P.EXE. These
are high-capacity versions of SQFIX which are capable of
handling areas containing more than 5400 messages.
Both versions of SQFIX32 have similar system requirements to
Squish/386 and both require a 386 or higher processor.
SQFIX32 uses the DOS/4GW extender. SQFIX32P is a native
OS/2 2.x application.
The 16-bit versions of SQFIX are still provided for
compatibility with older systems. However, the 32-bit
executables can be used on bases of any size, so the 16-bit
versions need not be kept if the 32-bit versions run on your
system.
* Added the "DupeLongHeader" keyword. If this keyword is
enabled, Squish will use the entire subject line when
performing header-based duplicate checking. Without this
keyword, Squish will check only the first 24 characters of
the subject field when performing duplicate checking.
- Squish will now try to create the directory for a
pass-through *.MSG area before writing the area's dupe file.
- With KillBlank enabled, Squish will also selectively delete
blank messages that contain file attaches, as long as the
destination of the message is your local system.
Blank file attaches that are destined to other systems will
be left alone, as in 1.10.
- SQINFO is now a little more picky about Squish bases, and it
identifies a few error types that were previously not
detected.
- Removed the "MsgAPI Startup" and "MsgAPI termination"
messages from the OS/2 MsgAPI code.
In addition, the following problems from version 1.10 were
corrected:
x Fixed SQPACK's area.dat-parsing routine so that it works
with areas that use long filenames with more than one dot,
such as "this.is.a.long.name.sqd".
x Squish will no longer crash if "Duplicates 0" is set in
SQUISH.CFG.
x Squish will now properly process the "DupeCheck" keyword.
Previously, Squish was always using the MSGID and header
algorithms, regardless of the setting in SQUISH.CFG.
x Fixed a compiler library bug that prevented SQ386P from
spawning archivers when running in a detached OS/2 session.
x Fixed a problem in the packet routing code that stopped
routed messages to 4D points of other systems from having
their headers stomped with the correct destination address
and password.
x Removed the erroneous "% gained" statistics code from
SQPACK.
x Fixed bug that caused Squish to incorrectly parse MSGID
lines that contained double quotes.
x Fixed problems in HPFS filename handling with SQSETP.
x When Squish encounters a netmail message which is too long
to pack, it will no longer skip the rest of the messages in
the area.
x Fixed a bug in the MsgAPI that caused Squish to erroneously
add junk characters to area tags when processing messages
that had a zero-length control field.
x Fixed the erroneous "message too large to pack" message.
This bug was sometimes encountered when trying to pack
Squish-format messages (which had been converted from the
*.MSG-format into Squish format using SQCONV for DOS) which
contained only kludge lines and did not have a terminating
NUL at the end of the original *.MSG message.
x Fixed a problem that caused an infinite loop when processing
"Send NoArc Normal World" in ROUTE.CFG.
x Squish will now gracefully skip linking an area if it does
not have enough memory to read in all of the area's
messages.
x If Squish cannot write a message to a given message area for
whatever reason, it will now roll back the area's duplicate
file to ensure that the message can be later tossed to the
area after the damage is corrected.
x Fixed a bug in the MsgAPI code that accidentally allowed
Squish to access a Squish base that was locked by another
process. This fix should correct some problems that occur
when using Maximus and Squish concurrently.
x Fixed the file-request processing logic to prevent improper
treatment of "!" characters at the beginning of a requested
filename.
x Fixed a problem that prevented Squish from writing to an
area if the max_msgs field for that base was set to 1.
x If Squish receives an insecure ACUPDATE message, it will
place one message in the log file (only) and skip all
following invalid ACUPDATE mesasges, instead of complaining
very verbosely and renaming the entire packet to .BAD.
SQUISH 1.10 REVISION NOTES -- SUMMARY OF CHANGES FROM 1.01
* Squish now comes in 16-bit and 32-bit versions, for both DOS
and OS/2. The 32-bit versions of Squish are particularly
useful for systems which carry large numbers of EchoMail
areas and have many downlinks.
See the following sections of the documentation for more
information:
INSTALLATION: 16-bit or 32-bit? SQ386 and SQ386P
SQ386 USAGE NOTES
The 32-bit DOS version uses the DOS/4GW extender (included).
The 32-bit OS/2 version is a native OS/2 2.x application.
* The OS/2 version of Squish comes with a new copy of
MSGAPI.DLL. A 32-bit version called MSGAPI32.DLL is also
provided.
* The Squish file access code was rewritten, and as a result,
message base access should be much faster. The new code
should be 100% compatible with older versions of Squish, so
older programs should be able to read and write the same
Squish areas.
In addition, the restriction of 5,200 messages per area has
been lifted. Squish areas can now be of any size, limited
only by available memory. (As long as the .SQI file can be
read into real or virtual memory, Squish can handle the
area.)
These changes were also propagated to MSGAPI.DLL and
MSGAPI32.DLL, so any OS/2 programs which use the .DLL should
be able to handle the larger Squish bases.
* The OS/2 version of Squish now includes "installable
feature" functionality. This allows third-party developers
to write .DLL modules that get called when Squish is
executing.
These feature hooks allow third-party code to be executed
every time Squish tosses, scans or packs a message.
Possible applications include message filtering, nodelist
checking and message bouncing, and many other additions.
Interested developers should see the Squish Developer's Kit
for more information.
* The new "NoStomp" keyword instructs Squish to not stamp over
the packet header with the interim destination address when
performing routing.
* Squish can now perform update requests from the command-
line, using the "SQUISH UPDATE" command.
* The "Buffers" keyword now allows each of the three main
buffers to be adjusted individually. The 16-bit versions of
Squish now support messages up to 63K in size, while the 32-
bit versions support messages up to 256K.
* Added the "KillIntransitFile" keyword.
* Added a "MaxArchive" keyword to control the maximum size of
archives created by Squish.
* Squish now supports multipass operation when 4D points are
being used, as long as no *.MSG areas are used. (To use
*.MSG areas with 4D points, single-pass operation must be
used.)
* The maximum line length in AREAS.BBS has been expanded to
1024 bytes.
* Squish now supports schedules which run through midnight.
* Exceptions can now be specified for the TinySeenbys keyword.
* Squish now supports an "Include" keyword in SQUISH.CFG.
* The -n command-line parameter can now be used to override
the LogFile keyword.
* The NetFile keyword can now include a "NoEcho" modifier to
prohibit Squish from tossing EchoMail from the directory in
question. Note that this option cannot be used in
conjunction with BatchUnarc.
* If a packet contains a message which is too long to be
tossed, Squish will rename the packet to .LNG (instead of
.BAD) after all of the other messages in the packet have
been tossed.
* The StripAttributes keyword can now be used to strip
attributes on a node-by-node basis.
* The new "-u" command-line switch can now be used to toggle
TossBadMsgs mode.
* The new "LinkMsgid" keyword instructs Squish to link message
bases using MSGID and REPLY kludges, instead of the standard
subject-based linking.
* The new "DupeCheck" keyword can be used to enable either or
both of header-based and MSGID-based dupe checking.
* Squish now supports broadcast message modification and
deletion, configurable on an area-by-area basis.
* SQFIX will now attempt to save the user's lastread pointers
file when fixing an area.
* Squish will now decompress archives in order of ascending
date, rather than simply searching for the file extension.
This is in addition to the date sorting that was previously
performed on packets alone.
* The BusyFlags keyword now supports InterMail-style busy
flags when running in ArcmailAttach mode.
* Squish now ensures that area definitions are consistent if
an area is duplicated in both SQUISH.CFG and AREAS.BBS.
(This means that the DupeArea should be placed in SQUISH.CFG
only, not in AREAS.BBS.)
