Cygwin errors after altering Windows command prompt shortcut (???)

Cygwin errors after altering Windows command prompt shortcut (???)

[Pat Tressel]

My Cygwin installation was working fine right up to the point where I
had to restore a Windows command prompt shortcut from backup.
Immediately afterward, commands run in the Cygwin shell window (the
one whose shortcut is created at the end of setup, that runs
Cygwin.bat) failed with errors like:

bash-4.1$ ls
      0 [main] bash 8316 child_info_fork::abort: cygreadline7.dll:
Loaded to different address: parent(0x3C0000) != child(0x320000)
bash: fork: retry: Resource temporarily unavailable
      0 [main] bash 7708 child_info_fork::abort: cygreadline7.dll:
Loaded to different address: parent(0x3C0000) != child(0x320000)
bash: fork: retry: Resource temporarily unavailable
...

Starting a new Cygwin shell instance got errors from bash before
entering a command.

Background:  Ok, this is really weird...  Don't know if any of it is
relevant except perhaps that the shortcut was recovered, but you might
find it amusing.  I did "git diff" in Windows command prompt.  When
git diff's pager happened to stop in some deleted code, which it
colors red by default, I ^C'd out.  Bad move.  That apparent left the
text color set to red.  I changed the color in the properties for the
window back to its original gray.  But after that, the colors were
just mixed up -- when git tried to display red, it came out yellow.
After checking that git had not modified its own color settings, and
that the properties including colors seemed to in settings associated
with the shortcut, the window, or with cmd.exe, I started with the
shortcut -- I recovered it back to the previous Windows restore point.
 That got the colors back to normal, and Windows command prompt was
functioning normally, so I didn't try to recover anything else.  To be
clear, I didn't recover the entire system back to the restore point,
just the shortcut.  But then...the very next command I did in a Cygwin
shell window failed, as above.

I wondered if the restore of the command prompt shortcut had replaced
something that the Cygwin shell or its shortcut or window was using.
(Windows regards both of them as the same in some sense -- both are
started as Windows commands in a Windows window, and Windows lumps
them together on the task bar.)  I made a new shortcut, but couldn't
get it to start in my home directory.  (The old shortcut had nothing
in its "Start in" field, but I don't know if that was due to damage.)
So I figured I'd run Cygwin setup.exe again and let it create the
shortcut.  Got a fresh copy of setup.exe -- it found a few things to
update, so it was doing more than just creating the shortcut.
Unfortunately, setup failed -- it reported a number of "Postinstall
script errors":

Package: _update-info-dir
    update-info-dir.sh exit code 254
Package: coreutils
    coreutils.sh exit code 254
Package: base-files
    base-files-profile.sh exit code 254
    base-files-mketc.sh exit code 254
Package: cygutils
    cygutils.sh exit code 254
Package: libgdk_pixbuf2.0_0
    gdk-pixbuf2.0.sh exit code 254
Package: shared-mime-info
    shared-mime-info.sh exit code 254
Package: libgtk2.0_0
    gtk2.0.sh exit code 254
Package: xorg-server
    xorg-server.sh exit code 254
Package: xinit
    xinit.sh exit code 254

That  update-info-dir isn't a package, but I set the rest to
reinstall, and tried again.  (Tried a different mirror, turned off
anti-virus and backup, in case something was interfering.  But I've
previously updated cygwin while both were running with no problem.)
After several tries, setup got down to failing on only one package:

Package: base-files
    base-files-profile.sh exit code 254

That one doesn't want to complete.  And with errors, apparently setup
won't create the shortcut.

:-(

So...any ideas what might be wrong?  Should I reinstall Cygwin?  Or
keep trying to reinstall base-files?  Or...?

Thanks!!

Did you update to Cygwin 1.7.11-1 already?

I ran the latest setup (see post for details, relevant section quoted
below) so I'd assume it attempted to install the latest version.
However, the main problem I'm reporting is that the install fails
repeatedly, so, no, it did not successfully update.  :-(  (Continued
below quote.)

I'll attach the setup.log.full from the last run (where I asked it to
reinstall base-files) -- that shows errors reported by bash (similar
to the ones in my original post):

It's even weirder, than you'd think.

Close all console windows, cleanup the color assignments, relogin your

Oooooh, that.  I could *not* remember "console".  I was thinking
"terminal" or "you know, whatever it is that Windows runs its command
prompt in" or "the thing that has the text color properties and the
quick edit mode".

(Off topic:  Huh.  So maybe git or msysgit was monkeying around with
the color table...maybe using a non-standard color?)

I rebooted.  Aaaand (drumroll) Cygwin setup ran to completion and
fixed the shortcut.

Yay!  Thanks, Andrey!!

Just curious...I wonder what was giving bash fits...

The MSYS part of msysgit doesn't muck with registry keys.  Maybe
something with tksh that it uses does.

I think it was his own hands.
Windows console colors assignment dialogue have a long-standing behavioral
issues, that can impact the end result, if you're unaware of them.

Forget those other things that might have been possible causes -- they
now look like red herrings.  This happened again recently, once after
the system hibernated, and once after a reboot.  (In the second case,
I believe there were no Cygwin windows open when the system was shut
down, but it's possible that the process had not finished exiting and
was killed by shutdown.)

Recall from the previous occurrence that restoring from the last
restore point caused the error to go away, but that's not a good
workaround, as it takes at least half an hour to make a restore point
or restore from it, and restoring throws away anything installed since
the last restore point.

This is a very recent version of Cygwin -- it was updated 6 days ago.

Any ideas what might be wrong?  Perhaps something that wasn't cleaned
up during shutdown if the process did get killed?

Thanks!

Re: Cygwin errors after altering Windows command prompt shortcut (???)

Just found rebaseall.  After the first run (not as administrator), the
error was still present, but the reported address was different.  Ran
it again as administrator, and after that the error went away.

Odd thing is that although I ran setup last week in order to install
something new, I'd been using Cygwin without errors since then, so
nothing was installed between the time it worked and when it stopped
working.

_Cygwin_ by itself, as in, an application for it's own needs, not rely on
specific registry settings.
However, there's a number of _system_ settings, which may affect behavior of any
application, that fall into certain criteria.
In case of HKCU\Console\*, it is any console window matching the name of a
subkey. Or any console window, for default color/font/behavior settings.
Likewise, application/library registration in
reg:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths
_will_ affect every application in the system.

Aha!  So those subkeys would likely only be present if one had
non-default values...  I already backed up HKEY_CURRENT_USER\Console,
so maybe I can delete its Cygwin subkey and see if anything changes.
(I think Git Bash put its own little self in there -- I see it has a
non-standard font.  I believe I started it once, said "don't need
that", and ignored its shortcut taking up space on my desktop
since...)

On my system, HKEY_CURRENT_USER\Console has a Cygwin subkey (and a Git
Bash subkey, but I don't use Git Bash).  I don't know if that is still
in use (given comments re. Cygwin not needing the registry any longer,
which I may have misinterpreted), but with the odd behavior, maybe it
is still in use.

These keys created when you mess with console properties of a running
application.
I don't touch them and I only have one bogus subkey mentioning "summary.bat"
Don't remember, what was that batch, though. I just deleted the subkey for
now.
