directory specified, and add it to sysIncPath only if it exists.
However, afterwards make tested for the presence of a -m option by
checking to see if sysIncPath was an empty list, and assumed that
the -m option was not used if it was empty. This obviously breaks
if -m specified a non-existent directory. So I have added a flag
that is set if the -m option is used, and I test that instead.
Make used to only use the search path for nodes that were pure
sources (not targets of other sources). This has been corrected
and now gnu-autoconf generated Makefiles work in directories other
than the source one.
- Suffix transformation rescanning:
Suffix transformations (.c.o:; cc ...) were only recognized in
the past when both suffixes were members of the suffix list.
Thus a sequence like:
.z.b:
echo ${.TARGET}
.SUFFIXES: .z
would cause .z.b: to be inserted as a regular target (and the main
target in this case). Other make programs always add rules that
start with a period in the transformation list and never consider
them as targets. We cannot do that (consider .depend files) so we
resort to scanning the list of the current targets every time a
suffix gets added, and we mutate existing targets that are now
valid transformation rules into transformation rules. If the
transformed target was also the main target, we set the main target
to be the next target in the targets list.
I.e. if you had a line in your Makefile:
../foo.o: foo.c
`..' would be added in the search path. The addition of such paths has
been now disabled. If a pathname contains a slash, then the directory
where such a file is found is not added to the search path. Of course
this eliminates most (all?) use of this function.
* differentiate between being connected, and being logged in
* cleanup some text messages
* support username & password ftp URLs (ftp://user:pass@host/) in non-proxy
situations; assume proxy supports it for proxy situations.
* cd to / before performing any autofetch transfers
* use strncasecmp in URL parsing. fix from <Todd.Miller@courtesan.com>
("MSDOSFS mount" is too big for %12s).
Note that this breaks naive parser scripts, but they would not parse
the earlier "MSDOSFS mount" line correctly, anyway.
* add "more" & "less" as synonyms for "page"
* move editline setup code into controlediting(), and call appropriately.
only setup setup terminal if going into interactive mode. inspired
by Todd Miller <todd.miller@courtesan.com>
- Fix globbing so that patterns that don't have a matching number of [] or {}
don't get expanded. (before the [ case got expanded to nothing!) This is
disabled.
* only echo "Passive mode" in verbose mode; scripts that use ftp
may get unwanted output otherwise
* disable progress bar and modification time preservation when
retreiving to a non-regular files. fixes progress bar getting in
way of "get file /dev/tty"
* setup el_init() et al if editing is set, not if fromatty.
TODO: migrate this to a function, and call if editing is turned on later
in the session. also implement edit_cleanup if editing is turned off
* call el_set() after setting SIGWINCH handler. This fixes the problem
when suspending in a non-cbreak shell (e.g, csh) would trash your tty mode.
* reset interactive mode correctly in auto_fetch() mget mode
* support remglobbing of auto_fetch arguments
* new flag - '-e'; disable editing
* "page file" == "get file |${PAGER-less}"
Bugfixes/cleanup:
* consistently use a trailing '.' on messages
* code cleanup, including buffer overrun fixes, use puts
and putchar in places, etc (inspired by OpenBSD mods)
* disable progress bar when local-file is a pipe or '-'
* skip \r in http headers
* fix remote ftpd slash bug more elegantly (so it works with ////)
* abort_remote(): check if cout==NULL before using it. should fix [bin/3273]
* fixed up cosmetic problems when complete_remote() generated errors from the
remote server (such as "no files found", "login with user and pass", ...)
done by adding extra argument to remglob(), which is a pointer to an error
buffer to put messages in rather than printing to stdout.
rwho: no hosts in /var/rwho.
message like ruptime does, for consistency. (Similarly, exit with exit
code 0, though i'm not sure that's "correct" for either.)
Add code to netstat to use libkvm to for kernel variables "mclbytes"
and "msize', and if found, use those for netstat -m rather than
compiled-in defaults.
1. ${.*} variables did not get expanded in dependencies.
2. expanded ${.*} variables in .USE dependencies can cause tree
restructuring; handle it.
3. in compat mode, expand .USE before evaluating the list of targets,
instead of doing .USE expansions on demand, because they can cause
tree restructuring.
EXPORTABLE_SYSTEM. Additionally, since it doesn't actually use libtelnet
for any of the 'interesting' features, it shouldn't be using libtelnet
at all (because that adds some serious headaches and problems, on ELF
systems with shared libraries, which cannot be easily addressed and
don't actually _have_ to be). Now it simply pulls in genget.c from
the libtelnet source, and builds it locally.
quotes. E.g. if left quote was "``" and right quote was "''", then
"``foo ``bar'' baz''" would yield "foo `bar' baz" when it should yield
"foo ``bar'' baz".
it uses pbstr() instead of doing the characters individually (in
reverse order) with putback().
Fix dodiv() so that divert(<out-of-range stream>) doesn't cause "divnum" to
return 0, but rather the stream number specified to divert(). Macros
like PUSHDIVERT/POPDIVERT rely on this. The new behaviour is compatible
with vendor m4 implementations.
barring any more little things people want added ...]
New features:
* progressmeter is now asynchronous, so "stalled" transfers can be
detected. "- stalled -" is displayed instead of the ETA in this case.
When the xfer resumes, the time that the xfer was stalled for is
factored out of the ETA. It is debatable whether this is better than
not factoring it out, but I like it this way (I.e, if it stalls for 8
seconds and the ETA was 30 seconds, when it resumes the ETA will still
be 30 seconds).
* verbosity can be disabled on the command line (-V), so that in auto-fetch
mode the only lines displayed will be a description of the file, and
the progress bar (if possible)
* if the screen is resized (and detected via the SIGWINCH signal), the
progress bar will rescale automatically.
Bugs fixed:
* progress bar will not use the last character on the line, as this can
cause problems on some terminals
* screen dimensions (via ioctl(TIOCWINSZ)) should use stdout not stdin
* progressmeter() used some vars before initialising them
* ^D will quit now. [fixes bin/3162]
* use hstrerror() to generate error message for host name lookup failure.
* use getcwd instead of getwd (it should have been OK, but why tempt fate?)
* auto-fetch transfers will always return a positive exit value upon failure
or interruption, relative to the file's position in argv[].
* remote completion of / will work, without putting a leading "///".
This is actually a bug in ftpd(1), where "NLST /" prefixes all names
with "//", but fixing every ftpd(1) is not an option...
probably never be completely supported here (since its internal vs.
external symbol handling is so annoying), but at least we can recognize
the ECOFF binaries and print something useful, on machines that use
them.
* Command line editing via editline(3) library.
* Context sensitive command and file completion, including remote files.
Enhancements to auto-fetch feature:
* Support for http:// URLs using the http protocol, including proxy HTTP
support via $htty_proxy if it's defined.
* The connection is kept open between successive files on the same host.
(obviously, this does not count for http requests.)
* Return value of ftp is 0 on no error, or the offset in argv[] of the file
which failed (i.e., argv[x] failed, ftp returns x).
* If the path in an ftp URL or classic format line has a trailing '/',
cd to the path and enter interactive mode. Fixes [bin/3011], albiet
requiring the user to help ftp in determining the operation.
Other changes:
* '-P port' works for normal ftp, and is the default for all classic style
auto-fetch transfers and for ftp URLs that don't specify the port.
(previously it would just work for the first xfer.)
* Some code moved into separated files along logical divisions.
* Editing and completion can be compiled out with -DSMALLFTP.
