- Remove all longjmp(3) calls from signal handlers. Instead, we post to an internal signal queue and check that periodically. All signal related code is now in sig.c, except for the SIGCHLD handler which remains in popen.c as it is intimately tied to routines there. - Handle SIGPIPE in type1() regardless of mime support, or else the handler in execute() will prevent our error code from being returned resulting in 'sawcom' not being set on the first command as it should. This only affected the initial behavior of the "next" command without mime support. - Add the 'T' flag to many commands in cmdtab.c that should not look like the first command. E.g., start mail on a mailbox with multiple messages, run "set foo", then "next", and watch the second message get displayed rather than the first as is the case without the first "set" command. - Add file descriptor and file handle leak detection. Enabled by DEBUG_FILE_LEAK. This will likely disappear in the future. - Fix a long standing (since import in 1993) longjmp() bug in edstop(): the jmpbuf was invalid when quit() is called at the end of main. - Fix a long standing bug (since import in 1993) in snarf() where it didn't strip whitespace correctly if the line consisted only of whitespace. - Lint cleanup. - New Feature: "Header" command. This allows miscellaneous header fields to be added to the header, e.g., "X-Organization:" or "Reply-To:" fields. - New Feature: "page-also" variable. This allows the specification of additional commands to page. It is more flexible than "crt". - Document the "pager-off" variable: if set, it disables paging entirely.

2006-11-28From Anon Ymous:christos
1) Statification of modules. 2) Implement the 'detach' and 'Detach' commands for extracting mime parts from messages. 3) Teach mail to output "In-Reply-To" and "References" header fields when replying so others can thread us. 4) Implement threading, sorting, and tagging, supported by the following commands: 'flatten', 'reverse', 'sort', 'thread', 'unthread', 'down', 'tset', 'up', 'expose', 'hide', 'tag', 'untag', 'invtags', 'tagbelow', 'hidetags', 'showtags'. See the manpage for details (when available - soon). 5) Implement a 'deldups' command to delete duplicate messages based on their "Message-Id" field, e.g., in replies to a mailing list that are also CCed to a subscriber. (This can also be accomplished with the threading and tagging commands.) 6) Implement 'ifdef' and 'ifndef' commands, and make the conditionals nestable (i.e., implement a conditional stack). The if/else/endif commands existed before, but they were primitive and undocumented. The 'if' command currently recognizes the "receiving", "sending", and "headersonly" mode keywords. 7) Teach the message selecting routine to understand regular expressions if "regex-search" is defined. Otherwise only case insensitive substring matches are done (as in the past). 8) Teach the message selection routine to understand boolean expressions. Improved "colon-modifier" support. See the manpage for details (when available - soon). 9) Extend paging to all commands (where relevant). 10) Add shell like piping and redirection of (standard) output (if "enable-piping" is defined). Extend completion to these contexts. 11) The manpage should follow soon!!!!
2006-10-31More fixes from Anon Ymous:christos
1) Removed the -B flag (it was stupid on my part) and added a short description indicating how to accomplish the same thing under the "Sending Mail" section of man mail(1). 2) Added a -H flag to dump the headers and exit. It takes optional flags to restrict to old, new, read, unread, and deleted messages (the later being kind of useless - it shares code with something that already had it). 3) Restored the 'Save' command which somehow got mistakenly removed in the last commit and add documentation for it! (My apologies to its author.) 4) Added a 'mkread' command to mark messages as read (the inverse of 'unread'). Should we also have a 'mknew' command? 5) Added a 'smopts' command to keep a database of addresses and sendmail options to be used when sending messages to those addresses. See man mail(1) for a fuller description. 6) Added 'indentpreamble' and 'indentpostscript' variables whose values are inserted before and after a quoted message (~m or ~M escapes). =20 7) Added string formatting abilities for the 'prompt', 'insertpreamble', 'insertpostscript', and header display strings. These strings support all the strftime() format parameters as well as many more specific to mail (see man mail(1)). 8) Fix the -a flag so that it only takes a single filename, unless "mime-attach-list" is defined. This is more conventional and avoids unexpected whitespace issues.

2006-09-18Jumbo mail patch from our anonymous user:christos
1) Use editline [optional]: Most of this code was borrowed from src/usr.bin/ftp. It does the appropriate editing, history, and completion for all mail commands (from cmdtab[]) and also does editing on header strings ('~h' inside the mail editor). 2) '-B' flag: This will suppress the "To:" line passed to sendmail. In most configurations it will lead to sendmail adding "To: undisclosed recipients;". Currently, AFAIK mail requires at least one exposed recipient address. 3) Comments in rcfile: Currently, comments in .mailrc are only supported if the first (non-white) character on a line is '#' followed by white space, i.e., '#' is a 'nop' command. This (trivial) patch allows the more normal/expected use of '#' as a comment character. It does not respect quoting, so that might be an objection which I should fix. 4) Sendmail option editing: This adds the sendmail option string to the strings editable by the '~h' command within the mail editor. Currently, you can only set this string from the command-line, which is particularly annoying when replying to mail. 5) Reply from: When replying to a message, grab the "To:" address from the message and, if there is only one such address and it does not match a list of allowed addresses (set in the "ReplyFrom" variable), pass it to sendmail as the "From:" address for the reply (with the '-f' option). I often make aliases for myself so that my primary address is not given out; if the alias gets out, I know who to blame. Unfortunately, a reply to such a message would normally use the primary address without this patch. A warning is displayed when this is going to happen so that it can be modified with '~h'. 6) CC and BCC lists: Allow '-c' and '-b' to accept white-space or ',' delimited lists. Currently, a white-space delimited list of addresses work, but a list of aliases will not get expanded. For example, currently: mail -c "foo bar" christos will fail to send mail to 'foo' and 'bar' if these are mail aliases (in ~/.mailrc); sendmail aliases (in /etc/aliases) do work. 7) pipe command: This pipes the current message into a shell command. I use this for quick decoding of uuencoded mail, but I can imagine it might be useful for decrypting encrypted mail, too. 8) show command: This command takes a list of variables and shows their values. It is probably stupid as the 'set' command without any argument displays all variable values. Of course, if there are a lot of variables you have to sift through the list for the one(s) you want.

when deciding whether to run $PAGER, otherwise it may start up the pager for a two line message if all 55 header lines are the subject of a .mailrc ignore command. (And no, I don't find this program directly useful for reading today's mail volumes, but it's great as a component run from wrapper scripts, pretty good for scanning archived mail, and more than adequate for sending mail.)
