Too bad this requires to commit to a git repo. If you cannot find a
recipe that doesn't need that, please show values of variables
involved in this abort. The relevant code fragment is this:
/* If window start is unchanged, we can reuse the whole matrix
as is, after adjusting glyph positions. No need to compute
the window end again, since its offset from Z hasn't changed. */
r0 = MATRIX_FIRST_TEXT_ROW (current_matrix);
if (CHARPOS (start) == MATRIX_ROW_START_CHARPOS (r0) + Z_delta
&& BYTEPOS (start) == MATRIX_ROW_START_BYTEPOS (r0) + Z_delta_bytes
/* PT must not be in a partially visible line. */
&& !(PT >= MATRIX_ROW_START_CHARPOS (row) + Z_delta
&& MATRIX_ROW_BOTTOM_Y (row) > window_text_bottom_y (w)))
{
/* Adjust positions in the glyph matrix. */
if (Z_delta || Z_delta_bytes)
{
struct glyph_row *r1
= MATRIX_BOTTOM_TEXT_ROW (current_matrix, w);
increment_matrix_positions (w->current_matrix,
MATRIX_ROW_VPOS (r0, current_matrix),
MATRIX_ROW_VPOS (r1, current_matrix),
Z_delta, Z_delta_bytes);
}
/* Set the cursor. */
row = row_containing_pos (w, PT, r0, NULL, 0);
if (row)
set_cursor_from_row (w, row, current_matrix, 0, 0, 0, 0);
else
emacs_abort ();
return 1;
}
So the values of PT, Z, and Z_BYTE are important. Also, the following
GDB commands can tell important details:
(gdb) pmtxrows current_matrix
Note that you need to be in the call-stack frame of this code, frame
#3 according to the backtrace you show, to be able to reference these
variables.
Thanks.

It is accurate. However, if you start GDB from the Emacs's src
directory, you will be free of that doubt.

Would your reply have been the same if it were any other VCS, save Bazaar?
Admittedly, the bug is not very stable. I was only able to reproduce it
2 out of 4 times I tried it, this time around.

I did that, but forgot to create ~/.gdbinit in advance to set the

If you can reproduce this with bzr (I tried, but couldn't), please
show the recipe. I have a number of local bzr repositories, and can
create new ones at will, so I can use them for testing. For any other
VCS, I have only remote repositories on my machine, and I don't dare
to run such tests for a remote repo. If you can set up some scratch
git repo for me at some URL, I will try using that to work on this
bug.
And yes, I try to stay away of git, and only use a handful of commands
with it. There are already people here whose refusal to use bzr is
silently tolerated, so I don't see why my desire not to touch git any
more than I have to should be met with a different reaction.

Is that conclusion correct? No. It was in the 3rd line: 0: edges=(1,77),enb=0,r2l=0,cont=0,trunc=(0,0),at_zv=0 1: edges=(77,78),enb=0,r2l=0,cont=0,trunc=(0,0),at_zv=0 2: edges=(78,79),enb=0,r2l=0,cont=0,trunc=(0,0),at_zv=0 As you see, the 3rd line begins with character position 78, and that's where point is. So the cursor should be displayed there. > > But I probably don't understand what you wanted to ask or tell. > > Figure out why row_containing_pos (w, PT, r0, NULL, 0) returned 0. That's easy: r0->enabled_p is zero (that's what enb=0 is about). And row_containing_pos immediately returns NULL in that case. > And why try_window_id was supposed to abort in this case and why > this abort didn't occur more frequently. My analysis concluded that it wasn't supposed to abort, just not call set_cursor_from_row in that case. The call to abort was added long ago, when row_containing_pos got a minor modification, and the person who made the change thought that perhaps that change will cause damage. I think we can remove that call to abort now. And if that causes any regressions, there's a more drastic way of calling GIVE_UP in that case.

Since we're talking about a DVCS, you'd have to have a local repository clone to interact with it. So you'll end up with a local repo anyway. I've seen the bug when trying to amend the latest commits in these two: https://github.com/mooz/js2-mode.git https://github.com/dgutov/diff-hl.git > And yes, I try to stay away of git, and only use a handful of commands > with it.

I don't think any of the people you mention are considered core contributors. And from casual contributors, many things can be tolerated (e.g. no tests, ChangeLog and NEWS entries), because a patch is often better than no patch. > Thanks, this was "the missing link".

I don't know how to make sure my commits are never pushed. I'm simply too afraid of git, sorry. I have a very simple workflow, which works with a couple of git repositories I need to track for the projects that use it to which I contribute. It took me a while to set up that workflow, including a couple of aliases I needed to keep me sane, and I'm trying very hard not to deviate from that workflow. > > And yes, I try to stay away of git, and only use a handful of commands > > with it.

I don't know, but the amount of display-related changes committed lately is very large. In any case, I don't see why try_window_id should be unable to handle the case of all matrix rows being not enabled. We must not call set_cursor_from_row with a NULL row, because that function cannot tolerate such situations; but other than that, I cannot find any reason for not handling such matrices, let alone aborting. > I've been using `vc-git-log-edit-toggle-amend' without crashes for > nearly a year now, since it's been added. If you can identify the last revision where this abort didn't happen, I could try figuring out what changed.

Aside from you not having commit rights, Git doesn't have anything analogous to Bzr's bound branches built-in, so 'git push' always has to be called explicitly (or one can write a custom hook). To reproduce this bug, the only git command you'd have to type is 'git clone', then edit some file inside, then `C-x v v' and `C-c C-e'. In all likelihood, though, you won't be able to reproduce it, since I can't do that starting from 'emacs -Q' either. Sorry about not trying that up until now.

Thanks, I will have a look. Do the situations that triggered the bug involve font changes? (The revision you pointed to made tracking of font changes be per frame, rather than global.) In any case, that revision was about making redisplay optimizations more aggressive, so it is small wonder that try_window_id, which is part of those optimizations, is now called in situations where previously it wasn't. IOW, it is quite possible that there's nothing wrong with try_window_id being invoked in these situations. > (TIL that 'git bisect', unlike its Bazaar counterpart, supports > filtering commits by files they touched. xdisp.c, in this example). The display engine is not limited to xdisp.c; dispnew.c and dispextern.h are important parts of it, and sometimes window.c and the display-specific back-ends (xterm.c and xfns.c for X and similarly for w32 and NS) are also involved. > >> Why scratch? > > > > Because it could be messed up by the testing. > > None of GitHub repositories are publicly writable, so there's zero > danger of that.

I know about "git push" vs "git commit". What I didn't know is what exactly do the Emacs commands you used do, in git terms, and how does that relate to commit and push and the myriad of their options. The only thing that was clear to me was that a commit is required, because that's what "C-x v v" does in a modified buffer. I know nothing about "C-c C-e" in that context. And even if I knew that "push" is not involved, committing to a repository that tracks upstream development (which is all I do with git) would need some way to subsequently un-commit that, something I don't know how to do with git. I didn't want to screw up my work on GNU Make and Gawk, I'm sure you will understand.

It just toggles the value of the "Amend" header and inserts the last commit's message, so that the user can edit it before committing. > And even if I knew that "push" is not involved, committing to a > repository that tracks upstream development (which is all I do with > git) would need some way to subsequently un-commit that, something I > don't know how to do with git.

But just in case you're eventually going to make time to study Git, 'git reset' is the command you're looking for. And speaking of experimenting, you can just create a new local repository, not tied to any remotes, with 'git init'.
