I still see that this is not working.  Terminal contents are not restored.
Can I set anything to resolve this?  Will the fix be in soon?
 
Thanks,

Larry,

It used to work for me, but a recent update has caused it to cease 
working for me, too. Unfortunately, I'm not sure which--wasn't there an 
ncurses update recently? Perhaps when it's convenient, I'll try to back 
up to see if that makes screen restore start working again.

One other thing I've noticed is that "less" restores the screen but Vim 
doesn't.

For the hell of it, "cygcheck -s -v" output is attached.

Randall Schulz

FWICS (acronym alert: "From What I Can See" :-) there is no difference. I've
been switching libncurses and ncurses and I don't think anything has
changed. Perhaps a change in the termcap?

Yes, but you don't get the credit.  It's been used before... :-p

Well, I've been reading some vim help.  A few interesting things surfaced.
For details, "help restorescreen", "help term", "help terminfo", and "help
xterm-screens" in vim.  FWIW, it works for me in an xterm, but doesn't in
the "bash window" (we *really* ought to come up with a better name for
that).  Looks like vim doesn't recognize TERM=cygwin and doesn't set t_ti
and t_te appropriately.  These two variables control the "alternate
screen" feature.  As they aren't even defined for TERM=cygwin, I don't
know how it ever worked (unless termcap/terminfo were changed recently).

Re: vim quits and cygwin window contents not restored

[Randall R Schulz]

Hi,

Some salient facts:

Vim uses ncurses6:

% cygcheck vim
Found: D:\cygwin\bin\vim.exe
D:/cygwin/bin/vim.exe
  D:\cygwin\bin\cygwin1.dll
    D:\WINNT\System32\KERNEL32.dll

  D:\cygwin\bin\cygintl-2.dll
    D:\cygwin\bin\cygiconv-2.dll
  D:\cygwin\bin\cygncurses6.dll


Less doesn't use ncurses at all (!):

% cygcheck less
Found: D:\cygwin\bin\less.exe
D:/cygwin/bin/less.exe
  D:\WINNT\System32\KERNEL32.dll
    D:\WINNT\System32\ntdll.dll
  D:\cygwin\bin\cygwin1.dll
  D:\cygwin\bin\cygpcre.dll


Ncurses6 has not been updated recently:

Terminfo, on the other hand, was recently updated:

% ll -R terminfo
terminfo:

-rwxrwxrwx    1 Administ None         1682 Mar  9 15:15 /usr/share/terminfo/r/rxvt-cygwin-native


So, my bet is on the terminfo for cygwin as the locus of the problem, 
whatever it is. Other reasonable hypotheses are that there's problem in 
ncurses or in how Vim uses it.

Yeah, the terminfo change is the "problem".   Updating to 5.3-1
allows me to reproduce the behavior.  Reverting to 5.2-3 restores
the original behavior.

Does the presence of quote marks indicate you don't consider this a problem?

The wording of the "updating ..." and "reverting ..." sentences is 
ambiguous to me. Are you saying that you do see the failure to restore 
the original window contents when Vim is quit or suspended under 
terminfo-5.3-1 and see the proper restore behavior under 5.2-3?

terminfo is a fork from ncurses -- but I try to keep it sync'ed. 
Recently, I built ncurses-5.3 for cygwin (it's available as a 'test' 
package right now) and while doing so, I resync'ed terminfo to the 
ncurses base.

I did this because the ncurses maintainer finally folded in most of 
Earnie Boyd's original changes for the "cygwin" terminal.  However, he 
did not include all of them.

In my foolishness, I figured that if the upstream maintainer had seen 
Earnie's patches, but opted to leave out a few codes, that he must have 
had a good reason to do so.  So I followed his lead.  (I never noticed a 
problem pre-release, because I do most of my work in an rxvt window; I 
did only minimal testing in a "DOSbox" TERM=cygwin shell.  Sorry. 
[doesn't everybody use rxvt?? <g>] )

I'll try to figure out which parts are missing, and reinstate them -- 
look for a new release (of terminfo-) sometime in the next week.

Try the following.  First, save /usr/share/terminfo/c/cygwin somewhere 
handy.  Then, download and save the attached file cygwin.terminfo, and run
  'tic cygwin.terminfo'
which will compile it and install it into your terminfo database.

You can also hand edit /etc/termcap (back it up, first) and paste the 
attached cygwin.termcap file into it, deleting the current definition.

Anyway, give that a shot.  You'll note there are a lot of question marks 
in the comments in the cygwin.terminfo file.  If anyone's feeling really 
ambitious and likes digging thru terminfo documentation, the 
fhandler_console.cc source code in cygwin, and playing with 
/usr/bin/tack.exe...

Chuck,

This works for me (Win2k SP2 console).  Vim restores the original screen
on exit, suspend, and command execution.  FYI, this also fixes the "vim
window title" problem, reported in
<http://cygwin.com/ml/cygwin/2003-03/msg02264.html>.  Thanks!
	Igor

Charles,

I must be missing something.

Since there were no attachments, I placed the text embedded in the 
message into a file named "cygwin.terminfo" and used "tic" as you 
prescribed. I get a diagnostic "Name collision between cygwin cygwin". 
I tried removing the existing terminfo entry, but the result is unchanged.

Then I saw this, so I figured that there are two text attachments that 
got merged into a blob of in-line text, so I took the last 20 lines 
beginning with "cygwin|ansi emulation for Cygwin:\" and gave them to 
tic, and it seems to work (tic likes it and the results reinstate 
screen context save and restore).

Could you clarify what's up here? Am I the only one who didn't see attachments?

Randall,

Since I knew a bit about termcap/terminfo formats, I figured there were
two files: tic input and a termcap entry.  The web archive inlined both
text attachments.  However, when I accessed the message from pine, it saw
both attachments separately.  I'd guess that your mailer also saw the
attachments as inline...

Igor is correct.  There were two attachments, but the web archive 
inlined them.  If you go to gmane, you'll see the attachments in their 
original form.

But that shouldn't matter too much.  The first attachment (or part) is 
the terminfo input -- the commentblock all the way down to the last 
"dense" block of 20 or so lines.  That "dense" block is the termcap 
entry.  You don't want to 'tic' that; it was generated from the longer 
file using 'tic -C' -- but any codes that termcap doesn't understand are 
dropped.  So converting it BACK to terminfo format is a lossy conversion.

Again, you want the first group.  But, if you're cut-n-pasting, you need 
to insure that each line begins with a tab, not 8 spaces (sometimes tic 
can be picky about that).

Yes, but your terminfo database entry is probably missing a few codes. 
Who knows if they are important...

I dunno; they looked fine to me....

Hi, Chuck,

Thanks for the clarification. I have no idea what was up with the MIME

Thanks for the clarification. I've set things straight with the 
terminfo entry. Vim seemed to work perfectly well with the termcap 
entry for some reason. The tabs all made it through intact.

Can I trouble you to explain why your termcap replaces something so 
different in the existing /etc/termcap file:

cygwin:\
     :xn@:op=\E[39;49m:Km=\E[M:te=\E[2J\E[?47l\E8:ti=\E7\E[?47h:tc=linux:

I understand that this entry incrementally modifies the "linux" entry. 
Your new one does not? You just decided to sever the connection? 
There's too much difference to handle this way? It was a bad idea for 
some reason?

Enquiring minds want to know. Dammit.

Just to avoid bridge burning, I added your new entry and renamed the 
old cygwin one.

No, it's just that the existing termcap is very very different in 
structure from the existing terminfo entry for cygwin.  Now, if you work 
thru all of the dependencies, you might end up with the same thing; I dunno.

But, the terminfo entry is a straight "specify everything, no backrefs 
to other terminals".  So, if you tic -C it, you get a "specify 
everything, no backrefs" termcap entry.  As to WHY the existing termcap 
entry references linux but the terminfo one does not, your guess is as 
good as mine.  Historical, perhaps?

IMO, "specify everything" is the right way to go here.  cygwin is not 
linux.  cygwin is not xterm.  cygwin is cygwin, with all of its own very 
special quirks...

Chuck,

I was meaning to write this up earlier, but work keeps getting in the way.

When I used your new termcap entry, "less" (when it's displaying output piped to it via its standard input but not when it is given a file name argument) tells me "WARNING: terminal is not fully functional".

The "lcygwin" is just to prevent a conflict without having to remove the old entry.

Now if I switch back (rename "cygwin" in the above to "wcygwin" and "lcygwin" to "cygwin"), less works as usual for both standard input and file name arguments.

Well, I hate to be brusque, but I don't maintain termcap, just terminfo. 
   I provided a termcap translation as an offhand thing; I didn't really 
think about it.  Perhaps I should have thought about it, and then not 
done it <g>.

Anyway, perhaps some codes were dropped in the terminfo -> termcap 
autoconversion.  Or perhaps my new-n-improved terminfo entry is wrong: 
but the only way to find out is to recompile less to use 
terminfo/ncurses, and run your testcase.

I don't plan on doing that; sorry.

If the *terminfo* entry breaks *existing* apps that use *ncurses*, then 
I want to know, and I'll fix it (patches gratefully accepted, etc etc). 
  Otherwise, I don't care.  Termcap is not my baby.

I don't mind, but if you hate doing or being a thing, why do or be it anyway?

It's no problem--I'll just stick with the previous "cygwin" termcap 
entry. But why send a termcap entry and then wash your hands of the 
consequences of it being used? You didn't include any disclaimers, so 
it seemed like the courteous thing to do to let you know about the problem.

terminfo is a fork from ncurses -- but I try to keep it sync'ed. 
Recently, I built ncurses-5.3 for cygwin (it's available as a 'test' 
package right now) and while doing so, I resync'ed terminfo to the 
ncurses base.

I did this because the ncurses maintainer finally folded in most of 
Earnie Boyd's original changes for the "cygwin" terminal.  However, he 
did not include all of them.

In my foolishness, I figured that if the upstream maintainer had seen 
Earnie's patches, but opted to leave out a few codes, that he must have 
had a good reason to do so.  So I followed his lead.  (I never noticed a 
problem pre-release, because I do most of my work in an rxvt window; I 
did only minimal testing in a "DOSbox" TERM=cygwin shell.  Sorry. 
[doesn't everybody use rxvt?? <g>] )

I'll try to figure out which parts are missing, and reinstate them -- 
look for a new release (of terminfo-) sometime in the next week.

OK. So I guess we can consider the symptom confirmed.

Igor's right. We need a name for the windows that are created for 
non-gui, character subsystem. Surely CMD.EXE is not involved in your 
scenario (which is the one I routinely use, too). I think "console" is OK.

When Jurgen mentioned "top" in his report on the output anomalies in 
"procps" I checked it for this symptom. It uses ncurses6 and also fails 
to restore the window contents.

Re: vim quits and cygwin window contents not restored

[lhall]

Hi Randall,

Oh it's a problem alright.  I'm just not sure the exact source and
whether this functionality is in conflict with something else that 5.3-1
was trying to fix.  I looked at the email archives for discussions 
surrounding terminfo and couldn't find anything current, except for 
Chuck's announcement and credit given to Thomas Dickey for some Cygwin
terminal changes.  Hm, guess I should've checked cygwin-apps too.  OK,
that's on my list.

Your interpretation of "updating" and "reverting" below is correct.  It
works for me with terminfo 5.2-3 and doesn't work with 5.3-1.  I'm using 
vim 6.1.300-1 in a cmd.exe window running bash (2.05b-8).

Does the presence of quote marks indicate you don't consider this a problem?

The wording of the "updating ..." and "reverting ..." sentences is 
ambiguous to me. Are you saying that you do see the failure to restore 
the original window contents when Vim is quit or suspended under 
terminfo-5.3-1 and see the proper restore behavior under 5.2-3?

RE: vim quits and cygwin window contents not restored

[Stephen Ehmann]

It used to work fine for me to but I am setting up a new machine with a
recent install of cygwin.  Did you install recently?

Refer to:

I still see that this is not working.  Terminal contents are not restored.
Can I set anything to resolve this?  Will the fix be in soon?
 
Thanks,
