     September 9, 1990                  UUPC/extended 1.08a changes summary

     RReevviissiioonn:

     This document applies to UUPC/extended version 1.08a, and was
     formatted on September 9, 1990 at 19:24:38.

     IInnttrroodduuccttiioonn:

     This file lists changes made to UUPC/extended since release 1.07g.
     See UUPC107.DOC for changes made between UUPC 1.05 and UUPC/extended
     1.07g.

     BBuuggss FFiixxeedd iinn VVeerrssiioonn 11.0088aa:

       1. Dates, including timezones, are now formatted by the C standard
          library routine s_t_r_f_t_i_m_e_.  This requires the addition of the
          environment variable TZ to the user's autoexec.bat file, such
          as:

                    SET TZ=EST5EDT or
                    SET TZ=CST6CDT or
                    SET TZ=MST7MDT or
                    SET TZ=PST8PDT

          and removing the t_z_o_f_f_s_e_t_=_ and t_z_n_a_m_e_=_ variables from the
          configuration file.  Once this conversion is done, the user need
          not worry about changing the time zone in the configuration file
          twice a year as was required with previous releases.

       2. Modified i_m_p_o_r_t_p_a_t_h_() t_o_ change file naming convention for local
          spool files to correct problems with duplicate file names; UNIX
          file names (which allow mixed case and more special characters)
          are now converted to MS-DOS file names in subdirectories.

          NOTE:  This conversion means that UUPC/extended 1.08 generated
          spool files will not be recongized by version 1.07, and
          vice-versa.  This means any mail queued for a remote host will be
          lost (actually, left in the spool directory) when UUPC 1.08 is
          installed. MORAL:  Be sure your spool directory is empty before
          installing UUPC 1.08.

       3. Altered L__i_n_v_o_k_e__p_a_g_e_r_ to use backslashes (\) in place of slashes
          (/) to list files.  Some external pagers can't handle the
          latter.

       4. If the incoming command line from another host exceded a fixed
          buffer length, buffer overflow occurred and the results,
          especially for rmail delivery, were unpredictable. Corrected
          d_c_x_q_t_() to use a BUFSIZ input buffer and to dynamically allocate
          strings copied from the line buffer.

       5. The fixed-length expect-string buffer made it difficult to login
          to a host when incoming connect messages exceed the length of the
          buffer, causing the login attempt to fail.  Also, a very high
          speed connection might have problems with the original algorithm,

          which seemed to do a complete search of the buffer every time a
          character was read.

          Corrected by modifying the expectstr() function of uupc to
          eliminate to the fixed length buffer.  The new code contains a
          largely new expectstr() function and a circular buffer search
          function.  It does only one string-compare for each character
          read, and can read an indefinite amount of input; the only
          restriction is on the size of the expect string (set by MAXMATCH,
          currently 64).

          Problem description and new code provided by John DuBois
          <[e-mail]).

       6. Altered temporary file name generated for edited outgoing mail to
          have extension of "TXT" instead of "TMP".

       7. If both 'save' and 'purge' options are active and a read letter
          is auto-saved, the system mailbox for the user is not deleted.
          Changed U_p_d_a_t_e_M_a_i_l_b_o_x_() to detect this condition and delete the
          system mail box.

     EEnnhhaanncceemmeennttss mmaaddee iinn VVeerrssiioonn 11.0088aa:

       1. Modified send/expect string processing to print up to the last
          511 bytes of the received string; leading/trailing control
          characters and spaces are trimmed before printing, and control
          characters in the displayed string are printed as question marks
          (?).

       2. Made SYSTEMS file optional; however, the user's mail server must
          still be listed in the PASSWD or SYSTEMS file.

       3. Modified packet machine to count errors on a per packet basis;
          this means that a file transfer will not fail because of errors
          which slow but do not halt the transfer, but a file transfer
          which is hung on a single bad packet will fail after MAXERR
          retries.

       4. Modified packet machine to report when it aborts a file transfer
          because an excessive number of errors.  Also added a message for
          number of errors per packet.

       5. Changed "Edit, Send, Abort?" prompt to "Abort, Continue, Edit,
          List, or Send? ", adding support for the "Continue" option to
          resume entering mail and "List" to display the body of the
          message to be sent.

       6. Added support for an alternate signature file (altsignature=) in
          the configuration file.  Code contributed by Philip Meese
          <cornwall![e-mail]>.

       7. Added support for toggling whether or a signature file is
          included via the options=autosign option.  Note the cchhaannggeedd

          default is noautosign to be compatible with selected UNIX
          systems.  Code contributed by Philip Meese
          <cornwall![e-mail]>.

       8. Added Sendmail-like tilde (~) commands:

               ~e      invoke editor on current message.\
               ~i      include body of current message, indented.
               ~I      include current message with headers, indented.
               ~m #    include body of message #, indented.
               ~M #    include message # with headers, indented.
               ~p      print message entered so far.
               ~P      print message entered so far using external pager.
               ~s      insert standard signature file.
               ~S      insert alternate signature file.
               ~?      display this mail subcommand list.

          Code contributed by Philip Meese <cornwall![e-mail]>.

       9. Converted sources to compile under Turbo C++ 1.0; this mostly
          involved adding a few missing semi-colons.  Also converted
          project files to Turbo C++ 1.0 format, which are non-ASCII.

      10. The *.LNK files have been dropped, replaced by files generated by
          Turbo Make 3.0 and by Microsoft nmake.

      11. Revised default aliases.txt file to include useful addresses.

      12. Broke UUPCBUGS into three files: CHANGES, BUGS, and UUPC107.

      13. Changed system connected messages to debug level 0.

      14. The source files have been reorganized to a single directory.

      15. The header file d_c_p_.h_ has been been broken up into the files
          d_c_p_.h_, d_c_p_x_f_e_r_.h_, d_c_p_g_p_k_t_.h_, and d_c_p_s_y_s_.h_.

      16. The file u_l_i_b_.c_ has been broken into u_l_i_b_.c_ and d_c_p_l_i_b_.c_.  This
          aids creating an OS/2 version of u_l_i_b_.c_ at a future date.

      17. The file h_o_s_t_.c_ has been broken into the files h_o_s_t_.c_ and h_l_i_b_.c_,
          with some function moved into t_i_m_e_s_t_m_p_.c_.

      18. UUPC/extended now compiles under Microsoft C 6.0; a makefile for
          Microsoft's nmake program is included with the source.  Note,
          however, that the Microsoft version is not fully debugged, and
          the following restrictions exist:

            a. MAIL requires ANSI.SYS if compiled under Microsoft C.

            b. UUIO doesn't include the Cntrl-Break handler if compiled
               under Microsoft C.

            c. UUPOLL doesn't issue a 'BREAK ON' if compiled under

               Microsoft C.

     BBuuggss FFiixxeedd iinn VVeerrssiioonn 11.0077jj:

       1. Specifying the -u (user mailbox) option after the -x (debug)
          option would reset the debug level.

       2. A transmit error (timeout, presumably, but maybe a NAK too) on a
          short packet (like at the end of the file) will cause UUPC to
          hang and eventually give up.  The code in g_s_p_a_c_k_() handles short
          packets by inserting a length byte (actually an "unused space"
          byte) at the beginning of the packet.  If the packet needs to be
          resent, it inserts the byte again!

          Discovered and corrected by Jordan Brown.

       3. If a duplicate entry exists in the PASSWD file, all other entries
          in the PASSWD file are skipped.

          Modified l_o_a_d_h_o_s_t_() to continue looping after a duplicate entry.

       4. Output from l_o_a_d_h_o_s_t_() is incorrectly identified as coming from
          c_h_e_c_k_n_a_m_e_().

       5. If a bad communication link exists between UUPC and the other
          host, file transfers appear to permanently hang.

          Reduced retry limit to 20 from 200.  This doesn't fix the
          underlying problem, but at least reduces its impact.

       6. If the "-b" (Blind carbon copy flag) is used on mail, the "-b" is
          handled as a local address and printed.

          Corrected l_m_a_i_l_() to suppress the delivery of mail to user '-b',
          and corrected s_e_n_d_o_n_e_() to suppress the header.

       7. Aliases of systems in the local domain are not located by
          c_h_e_c_k_n_a_m_e_().

          Added check for full system name before searching for name
          without domain suffix.

       8. If local system is not in the .UUCP domain, mail sent to it in
          the .UUCP domain is not delivered locally.

          Modified u_s_e_r__a_t__n_o_d_e_() to use c_h_e_c_k_n_a_m_e_() to determine if a
          system routed via the local system is in the routing table.

       9. UUCP "From " lines are interspersed with RFC-822 header lines.
          Only one UUCP "From " line should exist, and it should be first.

          Modified r_m_a_i_l_() to examine incoming mail for UUCP "From" line
          and replace it with Received: line.

      10. Temporary file names are now more unique, and UUPC doesn't
          overwrite existing temporary files.  Split mail.c into mail.c and
          maillib.c to improve compile and edit response times.

     EEnnhhaanncceemmeennttss mmaaddee iinn VVeerrssiioonn 11.0077jj:

       1. Deleted the obsolete HOWTOGET.IT file.

       2. Created options= configuration line in configuration file,
          allowing the boolean options:

            *  askcc
            *  autoedit
            *  autoprint
            *  dot
            *  fromsep
            *  pager
            *  purge
            *  save

          as listed or prefixed with "no" to set and unset options.  This
          allowed deleting the 'autoprint=' and 'fromsep=' option lines
          from the configuration file.  These new options are described in
          detail in the sample configuration file.

          NOTE: To make UUPC 1.07j behave the same as previous releases,
          the 'askcc' and 'autoprint' options must be set.  Otherwise,
          Carbon copies wil not be prompted for, nor will messages
          automatically print.

       3. Added the options (o) command to set and reset options allowed on
          the options line of the configuration file.  Also added the 'O'
          command to display the current setting of options.

       4. Added the "purge", option, which, when true, causes mailboxes to
          be automatically deleted when empty.

       5. Added the "pager" option, which, when true, causes the meaning of
          the "p" and "t" (print/type with external pager) commands to be
          exchanged with the "P" and "T" (print/type with internal pager)
          commands.

       6. Added the "save" configuration option to automatically save any
          read, answered, or forwarded message in "mbox" in the user's home
          directory when reading new incoming mail.

       7. Added the "dot" configuration option to allow message input to
          terminated by a single period (.) followed by a carriage return.

       8. Added the "askcc" configuration option to make prompting for
          carbon copies ("Cc:") optional.

       9. Added the "autoedit" configuration option to bypass prompting for
          text in interactive line mode and go directly into the user's

          editor, if desired.  This option is ignored if no editor is
          defined or the mail is not being sent from the console.

     EEnnhhaanncceemmeennttss mmaaddee iinn VVeerrssiioonn 11.0077ii:

       1. Allow new keyword a_u_t_o_p_r_i_n_t_=_N_O_ in user configuration file to
          suppress the automatic printing of messages.  If autoprint=NO is
          set, only one line message description is printed.

          Note: Changed to part of options line in 1.07j.

       2. Added the Toggle Autoprint (A) command.  Toggles between
          autoprint enabled and disabled.

          Note: Deleted in 1.07j, replaced by 'o autoprint' command.

       3. Moved prototype for FOPEN() from mlib.h into lib.h, where it
          belongs.

       4. Split router.c into hostable.c and router.c.

       5. Allow ~filename in save (s) and write (w) commands to save into
          another user's mailbox directly without know the configuration
          directory name for unsaved mail.

     BBuuggss FFiixxeedd iinn VVeerrssiioonn 11.0077hh:

       1. If incoming mail with a quoted name is replied to, a second set
          of quotes is added to the outgoing address.  Modified
          ExtractAddress to trim the incoming quotes as white space.

       2. The COMMZ100 communications handler didn't work.  Altered the
          handler to never disable interrupts on reads by playing with the
          input queue by hand; ZUUIO (Z-100 UUIO) now works at 1200 and
          2400 bps.

       3. Any alias which was actually a list of aliases was not properly
          expanded. Corrected E_x_t_r_a_c_t_A_d_d_r_e_s_s_() to use different selection
          criteria as to whether or not the full name of the was found.

       4. Once in a while, the "count of messages in mailbox" message
          wasn't formatted properly to overlay the count of messages being
          read like it was supposed to.  Corrected by deleting conditional
          that suppressed printing of "\b* " in C_r_e_a_t_e_B_o_x_().

       5. The 1.07g sample SYSTEMS file incorrectly showed the telephone
          number twice.

     EEnnhhaanncceemmeennttss mmaaddee iinn VVeerrssiioonn 11.0077hh:

       1. Modified l_o_g_i_n_ to use s_p_a_w_n_l_() in place of s_y_s_t_e_m_() to better
          determine if a command fails and save memory.
