In a `term' buffer, seemingly after any window configuration change, the
process filter triggers an error due to `term-current-row' being nil
unexpectedly.
Recipe:
emacs -Q
M-x toggle-debug-on-error
M-x term
RET
RET #repeatedly -- all is fine at this point...
C-c 2
RET
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p
nil)
term-down(1 t)
term-emulate-terminal(#<process terminal> "\015\033[K$
\015\n\032//home/phil\015\n")
That window config change could be C-c 2 or C-c 3 or, if already split,
C-c 1;
it doesn't seem to matter.
With an uncompiled `term-down':
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p
nil)
=(nil 0)
(and (= term-current-row 0) (< down 0))
(if (and (= term-current-row 0) (< down 0)) ...)
(let ((start-column (term-horizontal-column))) ...)
term-down(1 t)
term-emulate-terminal(#<process terminal> "\015\033[K$
\015\n\032//home/phil\015\n")
That test of (= term-current-row 0) occurs twice in the function.
Trivially, testing (bound-and-true-p term-current-row) beforehand in
both pieces of code circumvents the error and appears in practice to
resolve the issue, but I don't know whether that's the *right* fix.

Hmm, I'm not able to reproduce this, even though it makes sense to me
that my fix for Bug#30544 [1: a64c11a3aa] would cause this. Perhaps it
depends on your shell prompt as well?

I think changing them to function calls, i.e., (term-current-row)
instead of term-current-row would be the right thing; all the other term
functions use the function rather than accessing the variable directly.

I do have a non-trivial prompt; but after setting PS1="$ " I still see
the same issue, so I'm unsure whether that's a factor. My shell is
bash.

That sounds sane, and I can confirm that it fixes the problem.

Hmm, maybe it's a difference in bash versions? I tried adding a newline
to my prompt with PS1=$'one\ntwo$ ', but bash doesn't send the newline
after the terminal resizes. Seems it's clever enough just to redraw the
last line.
GNU bash, version 4.4.12(1)-release (x86_64-pc-linux-gnu)
And since terminal-emulate-terminal doesn't receive a \n character, it
doesn't call term-down before calling (term-current-row) near the end of
that function:
(when (>= (term-current-row) term-height)
(term-handle-deferred-scroll))
So I definitely can't see how you trigger this with PS1="$ ", but
perhaps your version of bash sends a newline for some other reason? Can
you show the backtrace with PS1="$ "?

Okay, here's the patch with message. Eli, should I apply this to
emacs-26? I believe it's safe because the term-current-row function
simply returns the value of the term-current-row variable if that is
non-nil. Hence it should only affect cases where we were going to
signal an error due to type-mismatch anyway.

Subject: [PATCH] Don't assume term-current-row cache is valid (Bug#31193)
* lisp/term.el (term-down): Call `term-current-row' instead of
directly accessing the variable `term-current-row. Following a resize
of the terminal's window, `term-current-row' is reset to nil, so it is
not safe to assume it is a number.

Mine is:
GNU bash, version 4.3.11(1)-release (x86_64-pc-linux-gnu)
> Can you show the backtrace with PS1="$ "?
Sure. This is with a .bashrc containing only that setting, and an
otherwise blank-slate $HOME directory, in case anything else I was
doing had an effect. It might still be due to system-wide config,
but the bash version difference seems as likely as anything else?

Hmm, yeah, it looks like your bash adds a "\r\n" (\015 is \r) after the
prompt, while mine doesn't. Although, wouldn't that extra \n leave your
cursor one row below the prompt?
I also don't get the \032/<path>\r\n unless I do a 'cd'.

In practice the carriage return shunts the cursor back to the start of
the
prompt that I was already at, and then gets 'stuck' there -- no new line
is
created.
Typing RET again triggers the same error (with no change to the buffer),
but as soon as I start typing other keys, functionality is restored.
> I also don't get the \032/<path>\r\n unless I do a 'cd'.
I observe that whenever I execute a shell command (or just enter a blank
line) and then trigger the error, I get this the first time:
term-emulate-terminal(#<process terminal> "\015\033[K$\015\n")
but repeatedly re-triggering the error gives me this every time:
term-emulate-terminal(#<process terminal>
"\015\033[K$\015\n\032/<path>\015\n$")
(until I next enter a command or blank line.)
The <path> matches the directory tracking -- I can affect it with cd.
(but setting default-directory does not affect it).

I could reproduce the error when using bash 4.3. The main difference in
versions seems to be that bash-4.4 repaints the last line of the prompt
in reponse to the resize event, whereas bash-4.3 doesn't respond to that
event; it just waits for the next user input.

Although I never got this short string. I always get
"\015\033[K<prompt>\015\n\032/<path>\015\n<prompt>". Not really that
important, it's just kind of tickling my curiosity.
Anyways, pushed the fixed to emacs-26.

I've just compiled bash 4.4.12 and confirmed that this issue
does not occur with that version.
GNU bash, version 4.4.12(1)-release (x86_64-unknown-linux-gnu)

And conversely the issue *does* occur with both bash-4.3.tar.gz and
bash-4.3.30.tar.gz if I compile those from source, so you ought to be
able to replicate that behaviour for yourself with either of those.

Yes, please.

Agreed.
