- 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.
* When installing hard links and using a metalog, if -o, -g, -m, or -f
args were explicitly specified on the command line, then believe them,
but do not implicitly believe uname/gname/mode/flags from the file
system.
* Add a size= field (only for plain files).
* Output fields in the same order used by mtree.
(which can shorten it) because the code that issues delimiters depends
on it being null-terminated. This caused e.g. paste -d '\0' a b to
print a '0' at the beginning of each line. Closes PR 41159.
address space available to processes. this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- patch sh, and csh to notice RLIMIT_AS. (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information. (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897. it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)
executable. Remove this so that different compiles can be binary
compared. rcsid's for all files are already embedded in the executable
so versions can be easily distinguished. (I didn't catch this on
previous passes because I did my builds on the same day.)
Note: there's a special rule for main.o in Makefile with a purpose I
can't actually discern -- I think it isn't needed, and I've flagged it
with a comment.
ht_new()... So actually rename it to condmkoptions to avoid confusion.
Reported build failure on amd64 (strange that I wouldn't get it on i386) on
current-users by Kurt Schreiner.
