- Encapsulated all the content-transfer-encoding stuff in mime_codecs.c
- Replaced calls of strtol(3) with a handcrafted version that allows simple
error checking by testing the return value. This allows to easily add
special code to handle illegal QP sequences.
Amend the previous commit to support zone-style RFC 822 dates.
RFC 5322 marks this zone-style as obsolete (obs-zone), but still supports it.
But then, even if you don't wanna support military style single-letter zones,
the UT zone exists and will not be supported by this commit.
The changes here are not strictly correct (since not all possible
single-letter zones are assigned, and only *UT* has two letters),
but which will match all thre possible *obs-zone* forms.
Compiled and tested on a single MBOX.
- preallocate child struct, since the signal handler can be called before
wait_child, and we cannot allocate a child struct there. there is a signal
race still here if the program exits and the signal handler is called before
we allocate the struct.
across setjmp/longjmp.
Inspired by PR 41255 from Kurt Lidl, but this change makes "com" a
volatile pointer to const non-volatile data, whereas the PR made it a
non-volatile pointer to const volatile data.
- 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.
