This was two years ago, but the patch doesn't seem to be applied?  It
was a rather obscure timing-related (but serious) bug.

Noam, did Eli's explanation help?

It prevents us from re-using the same portion of buffer text for
matching both at start and at end of the file.  This could happen,
e.g., with buffers whose contents is the same character, and a file
whose contents is mostly the same, but larger, and with a few
different characters in the middle.  Then the "same_at_end" loop could
inadvertently match a part of the buffer that was already matched by
the "same_at_start" loop.

The overlap expression computes the portion of the buffer that was
matched by both "same_at_start" and "same_at_end" loops.

This seems to fix the scenario you gave in #17.  I don't quite
understand what the overlap expression is trying to compute though.

Of course. But it seems to me we should have the information we need to
keep the Emacs processing self-consistent whether we iterate or not.
Other code in the function already clearly expects that the number of
bytes we can read may be different from st_size.

(Arguably, in case we're trying to preserve point or markers in a later
part of the file than might have been rewritten so far, it might be
desirable for insert-file-contents to restart or pause briefly and retry
reading more content if it detects a change, but I think that's mostly a
separate question.)

I've finally reproduced the problem. A key issue was that the whole
block containing the failing code would be skipped by the conditional
below if the coding system were "undecided", which seems to be the norm
in my testing with "emacs -Q", but not in my working environment for
whatever reason; maybe one of the minor modes I've loaded is setting a
more specific coding system.

  if (!NILP (replace)
      && BEGV < ZV
      && (NILP (coding_system)
	  || ! CODING_REQUIRE_DECODING (&coding)))

If the coding system is "undecided-unix", we enter this block, and I can
get it to blow up.

Recipe:

Get two similar files differing in the middle; I started with emacs-25
charset.h:

    cp .../src/charset.h file.h
    sed -e 400,499s/a/b/g < file.h > file2.h

Set a breakpoint just after the fstat call in Finsert_file_contents,
run emacs -Q, and read in file.h (continuing whenever the breakpoint is
hit). Turn on auto-revert-mode in the buffer.

Set the coding system with "C-x RET f" to "undecided-unix". That marks
the buffer as modified, so clear that by saving the file.

Copy file2.h over file.h, and when the breakpoint is triggered, change
st.st_size to zero, to simulate rereading before the file overwriting
has finished, and continue. My debugging printfs show that an
out-of-range same_at_end is generated as in my original case:

    (gdb) c
    Continuing.
    Finsert_file_contents:3871: same_at_start=13993 same_at_end=17747
         st_size=0 ZV=19498
      => overlap=15743
      => new same_at_end=33490

    ../../src/marker.c:297: Emacs fatal error: assertion failed: BUF_BEG_BYTE (b) <= bytepos && bytepos <= BUF_Z_BYTE (b)

That's my guess. Or, more specifically, between the fstat and attempting
to go ahead and read data anyway.

But I did a few experiments with truncating the file and using a
breakpoint after the fstat to stall Emacs while I restored the file (so
the size appeared to be zero but all the data was readable), and nothing
interesting happened. That part of the function seems to be trying to
figure out if some of the beginning and end of the file are unchanged
from before, so I think maybe it also requires having some part in the
middle changed, or one version of the file being shorter than the other.
I'll run a few more experiments today to see.

If the file is large, and being frequently updated in small increments,
that could delay us considerably, as we restart the process multiple
times. (Some of the files I use auto-revert mode on are log files in the
tens of megabytes. Last I tried, auto-revert-tail-mode didn't cope
nicely with the case where the file got truncated and rewritten, so
reverting the whole file seems to be the way to go for now.) And if we
put a limit on the number of iterations, the last time around we'll
still need to get it right.

There's code there doing lseek and read calls; we should be able to keep
track of the last file position we read from, if that's not already
derivable from existing variables visible at that point.

So you are saying that the file's contents was updated between the
time we called 'fstat' at the beginning of the function and the time
we used st.st_size in the above snippet?

If so, perhaps we should call 'fstat' again each time we want to use
st.st_size, and retry from the beginning if we find a mismatch?

> I haven't managed to reproduce this so far.

You could artificially modify the value of st.st_size in the debugger,
and then see what happens.

Thanks.

I'm running the emacs-25 branch as of revision a1f221b, but with commit
d82f24b reverted (attempting to debug #23013), and built with
MARKER_DEBUG enabled (as Eli pointed out, probably not relevant to
#23013) along with assertions.

I was using "git" to update a source tree while about twenty files from
it were loaded into Emacs buffers. Auto-revert was triggered; during the
process, Finsert_file_contents was loading a Perl file when it invoked
BYTE_TO_CHAR:

	  /* Don't try to reuse the same piece of text twice.  */
	  overlap =3D (same_at_start - BEGV_BYTE
		     - (same_at_end
			+ (! NILP (end) ? end_offset : st.st_size) - ZV_BYTE));
	  if (overlap > 0)
	    same_at_end +=3D overlap;
	  same_at_end_charpos =3D BYTE_TO_CHAR (same_at_end);

...with same_at_end well out of range (Z_BYTE=3D12451, same_at_end=3D24673).
The reverting appears to have happened while the file was in the process
of being updated, as st.st_size is zero.

The "end" argument is nil, so the conditional expression will use the
st_size value (zero). So with same_at_start=3D12223, BEGV_BYTE=3D1, and
ZV_BYTE=3D12451, the "overlap" value will be 24673 minus the (old) value
of same_at_end. If that difference doesn't go negative, we'll set
same_at_end to 24673, which is the value seen in the next frame down.
(The "overlap" variable isn't visible from gdb at this point.)

So in buf_bytepos_to_charpos, the initial range check assertion fails,
and Emacs dies.

I haven't managed to reproduce this so far.
