That only works if Guile knows about the fd though, and Guile currently does not know about it's own finalisation pipe, which I think is the cause of <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D48563>, so currently still fragile ...

Just my 2=C2=A2, from my experience, Guile uses a lot of fds (`guile -q` us=
es
15). I'm not sure it would be safe or advisable to move fds, since we
cannot be sure that they're backing ports or not, and if they're not it
would break things. In general, the Guile ports/fds interface works ok,
but there is a lot of code that is fragile and doesn't handle
edge-cases.

Could this help?:
(from man 2 openat (scroll down a fair bit):
-8<---------------cut here---------------start------------->8---
There are two main use cases for O_TMPFILE:
* Improved tmpfile(3) functionality: race-free creation of temporary files that (1) are automatically
deleted when closed; (2) can never be reached via any pathname; (3) are not subject to symlink at‐
tacks; and (4) do not require the caller to devise unique names.
* Creating a file that is initially invisible, which is then populated with data and adjusted to have
appropriate filesystem attributes (fchown(2), fchmod(2), fsetxattr(2), etc.) before being atomi‐
cally linked into the filesystem in a fully formed state (using linkat(2) as described above).
O_TMPFILE requires support by the underlying filesystem; only a subset of Linux filesystems provide
that support. In the initial implementation, support was provided in the ext2, ext3, ext4, UDF,
Minix, and shmem filesystems. Support for other filesystems has subsequently been added as follows:
XFS (Linux 3.15); Btrfs (Linux 3.16); F2FS (Linux 3.16); and ubifs (Linux 4.9)
--8<---------------cut here---------------end--------------->8---
BTW, IIRC, this can be used to create an invisible file that
can be mmap-ed, and the mmap will persist when you delete
the file. Which then can be used as an anonymous buffer
passed to wayland, along with metadate saying what the buffer
contains, e.g. different kinds of rgb or rgba permutations
and encodings, (or anything, which you can tell wayland just
to keep track of for you.
You need a directory for openat, so probably
XDG_RUNTIME_DIR=/run/user/1000
is suitable if it exists. Worked in my case.

Yes, I agree those are good reasons to avoid a temporary file if we can. To that end, do you know if we can somehow force Guile to use a specific file descriptor for the pipe? In the patch I wrote earlier, which uses redirection, the problem was that I could not control Guile's choice of file descriptors. Guile chose file descriptor 19 for one end of the pipe, and I don't know how to make it use anything else. If we can arrange for Guile to consistently use file descriptor 7, for example, then probably it would work in all the shell I've tested. I wonder if maybe I can just duplicate the file descriptor? I don't know; if for example Guile reserves all the file descriptors below 10 for other uses, it might be hard. What do you think? Is there a way to do it? =2D-=20 Chris PGP: https://savannah.gnu.org/people/viewgpg.php?user_id=3D106836 --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQJJBAEBCAAzFiEEy/WXVcvn5+/vGD+x3UCaFdgiRp0FAmK3PUoVHGNtbWFydXNp Y2hAZ21haWwuY29tAAoJEN1AmhXYIkadFZcQAL0FO531KUuCaeazN5nba4ZP/aPS 1qjXKKrWxU9QR2r1HZERoCglSBxOp2Kpkl81mD/3am6hvZWS9Z0h1uIHEh8NzPzB eU6gfZKG26PLD3h2o8ffrxT8UiTuzzFmyRopPnyKIqIxi6yOu9CZENS0Yxrp9D/I GllMJBKRaGYJxidLRhq3uhn6AiEKKSNt6FP3BkSbqmZqrPKGXv1JWVCHDkVG0zXS 3A67Dm9Fk6xP974NjyfDLW3gOkRmRFkRekg8dDNDlh607iHErWmODF5i7XMn8qjp pcXmxGiy9PEGcJd9Y8ZIH9s++96PsZjtWPNvl31gzOaG7RFNuW2itz5xiHhvl8e1 qlXoTNOBKa2qqSXNKn98j+u+RPkxYtnjabLCVh1HPr+RvsMankZgKi3fDX3SQQ+U kH4bPjCyvxHzQuOtj0dVCAoYkBwWxOLu+qL1+7KRwhWowBKyDXDnGmHweeCGSsEJ 3H0Z5s5RqpHeJDZJkoTsJeS7bjZyeivw1Ktg4Rp/GCk/H/oioEoKPk8YWMrAH/T7 65Bq4tcgFODnPenB29a7XiUa6/s3Ov/GGXtD4Sex97acMtPImiMlGn4Vrr+aazVZ Ef+QsquE5SqmifhOZeVkW/duLrQucFhNJX+QipNmXzpwcrinr7HSRY6vF9KrJy9F 33Oj910Xl4imyP8K =0+4i -----END PGP SIGNATURE----- --=-=-=--

Hi Ludo & Everyone,
Chris Marusich <cmmarusich@HIDDEN> writes:
> Is it OK to rely on shell redirection?
It turns out that it is probably not OK to rely on shell redirection in
this case, after all. For example, "dash does not support multi-digit
file descriptors":
https://bugs.launchpad.net/ubuntu/+source/dash/+bug/249620
Indeed, the patch I proposed earlier to rely on shell redirection caused
a command like
./pre-inst-env env SHELL=3D/gnu/store/nm0hccsphymxi8c24xmg6ixm9vcf25xb-dash=
-0.5.11.5/bin/dash guix shell --check --container -D guix
to hang. It hangs because the FD Guile chooses to create and embed in
the script is 19 (on my machine, at least). A redirection like
"env >&19" causes dash to error out, so no environment information gets
sent back to the parent process. The same issue seemed to occur for the
ksh from our oksh package.
To resolve this, I changed the code so that it just writes to a
temporary file. This is simple and more robust. With the attached
patch, I was able to use a command like the one above to verify that
"guix environment --check" works correctly for Guix-built bash, dash,
ksh, fish, zsh, and ash. I also verified that it works for Fedora's
/bin/sh and /bin/bash.
What do you think of this file-based approach? Supporting many
different shells is pretty tricky, but I think this patch does a good
enough job.

Subject: [PATCH] environment: Prevent PS1 from clobbering output in 'check'.
Fixes: <https://issues.guix.gnu.org/51466>.
* guix/scripts/environment.scm (child-shell-environment) [temporary-file-po=
rt]
[temporary-file]: New local variables.
[script]: Redirect stdout to the temporary file.
[lines]: In the parent, send the script to the shell, wait for the shell to
exit, and then read lines from the temporary file. Use a dynamic-wind
expression to ensure we always close port, close temporary-file-port, and
delete temporary-file.

Sorry again, but I found the source:
tl;dr: These functions are defined in
/usr/share/bash-completion/bash_completion
which looks awful kludgey to me, (however clever :)
There is a reference to
http://lists.gnu.org/archive/html/bug-bash/2009-03/msg00155.html
in the header comments for
_quote_readline_by_ref ()
I also found
https://askubuntu.com/questions/571544/bash-tab-completion-bash-unexpected-eof-while-looking-for-matching-bash
My bet is there is at least one bug active now.
Completion is really nice when it works, but IMO they certainly
shouldn't use a name like unadorned ``quote'' in their implementation.
And I think it would be prettier in scheme :)
Lots could be prettier if bash could be extended with scheme.
I'm about out of time to chase this, but I expect to bump into it again ;/
HTH.

There are a couple functions without prefixed underscore too,
which invoke some underscore-prefixed ones that look too trusting
of their arguments if you ask me: can someone declare these safe?
I think I can grok quote () ...
(escape single quotes and enclose result in single quotes, trusting bash state)
But what if I want to define my own function quote?? How would I know I was
overriding this? I really don't like my programming space occupied by unknowns :-(
--8<---------------cut here---------------start------------->8---
quote ()
{
local quoted=${1//\'/\'\\\'\'};
printf "'%s'" "$quoted"
}
--8<---------------cut here---------------end--------------->8---
but this one below will take more time than I want to spend on code
I'm not intentionally going to use, and which invites name clashes
in my command name space :-(
--8<---------------cut here---------------start------------->8---
quote_readline ()
{
local quoted;
_quote_readline_by_ref "$1" ret;
printf %s "$ret"
}
--8<---------------cut here---------------end--------------->8---
where the above calls this:
--8<---------------cut here---------------start------------->8---
_quote_readline_by_ref ()
{
if [ -z "$1" ]; then
printf -v $2 %s "$1";
else
if [[ $1 == \'* ]]; then
printf -v $2 %s "${1:1}";
else
if [[ $1 == ~* ]]; then
printf -v $2 ~%q "${1:1}";
else
printf -v $2 %q "$1";
fi;
fi;
fi;
[[ ${!2} == \$* ]] && eval $2=${!2}
}
--8<---------------cut here---------------end--------------->8---
HTH somehow.

Hi Chris,
Did you observe this behaviour inside a git repo directory?
I wonder if this git security thing could be relevant:
https://lwn.net/Articles/892755/
It makes also me wonder about readline completion stuff
possibly interacting. Isn't that implemented with readline?
I have had some mystery bash parsing errors, and I noticed
set|less
shows a heck of a lot of functions defined that I don't
remember seeing in the past.
Anyway, shouldn't stuff like that have better hygiene than just prefixed
_underscore ? Or maybe set|less doesn't show all that on your system?
Disclaimer: I played a lot of games trying to make stuff conditional
at login, where I renamed .bash_profile and .bashrc (e.g. .my_bashrc)
which brought .profile into play, and I messed with the downstream
of that to source some .my_'s conditionally, so I've go a fragile mess right now ;/
Anyway, did you determine why things changed in the first place?
Or will this be a whack-a-mole game with future weirdnesses? :)
Semms like IWBN to have interfaces governed by contracts :)
Best,
Bengt Richter

Hi Ludo,
Thank you for the review!

Before pushing, I did some more tests to make sure it was still working.
When I did this, I noticed that read-line was no longer returning
strings that end in "\r". This prevents child-shell-environment from
behaving correctly, since it incorrectly assumes that all the lines end
in "\r", stripping it off unconditionally. In the past, I'm sure
read-line was returning strings that end in "\r". I don't know what
changed, but I've attached a second patch that fixes this issue, also.
Unless you have more feedback, I'll go ahead and push both patches to
master in a few days.

Subject: [PATCH] environment: Don't assume that lines have a trailing "\r".
I've noticed that the child-shell-environment procedure is misbehaving on my
computer because the lines returned by read-line do not have a trailing "\r=
".
In the past, I recall that such lines did in fact have a trailing "\r". I'm
not sure why it changed, but it seems prudent to just rewrite this code to
tolerate both cases, since it seems that both cases can happen.
* guix/scripts/environment.scm (child-shell-environment) [lines]: Instead of
checking if the line exactly matches "GUIX_CHECK_DONE\r"; check if the line
begins with "GUIX_CHECK_DONE". Instead of always stripping the trailing
character from the line, only do it if the line has a trailing "\r".

I didn't test one specifically. It might work with just one, but it did
work with three. If we want to proceed with the "echo" approach, let me
know and I'll test just one echo to see if that is reliable enough.

I see. Yes, I'll do that if we decide to go with the echo-based
approach.

I recall that I tried removing PS1, and I still had trouble. I believe
it was because even if we unset PS1 as the very first command we do, the
original prompt is still printed. Foreign distros usually set PS1 to
something, and whatever that is will be printed before we have a chance
to input any commands. It's hard to avoid that in general.
> Thoughts?
One alternative method I tried successfully in a variety of shells was
to use shell redirection (see attached). I like this approach.
However, this will only work in shells that support redirection. I
recall testing with bash, ash (busybox's shell), dash, zsh, fish, ksh,
and csh. I recall that only csh failed, since it doesn't support
redirection.
I personally like the attached patch better than what I proposed
earlier. The earlier patch just echoes a few times. Presumably, it
only works because the PS1 prompt is likely (but not guaranteed) to be
emitted before the last of the echo commands finishes printing. I'd
rather just control the desired output and ignore PS1 entirely, and that
is what the attached patch accomplishes using FDs. However, if support
for shells without redirection is a requirement, then maybe the original
hack (echo a few times) is OK, or perhaps we need something else.
How would you like to proceed? Is it OK to rely on shell redirection?

parent, close shell-pipe-out before sending the script to the shell. Read
lines from shell-pipe-in, not port, so that the shell's PS1 prompt cannot
clobber the lines. Close shell-pipe-in just before waiting on the child.

Should solve https://issues.guix.gnu.org/51466.
This redirects the env command's output to a temporary file so that
there is no way to get it mixed with the shell's output (like PS1).
Additionnally:
- Remove GUIX-CHECK-DONE and read: I don't think there is a need for
them as discarding the output until the shell exits is enough to
guarantee the environment has been dumped. Sadly, Linux doesn't
report EOF but EIO when the shell exits and the pty gets closed hence
the catch/throw.
- Don't try to parse environment variables by splitting them on \n,
instead use env's -0 option to separate environment variables with
\0. This prevent incorrect parsing of some multi-line variables
(e.g.: f() { echo "hello"; }; declare -fx f) but isn't standard.
* guix/scripts/environment.scm (child-shell-environment): make
environment variables parsing more robust.
* tests/guix-environment.sh: add a simple test that was reliably
failing on my machine.

I don't think we have to hack our way around the shell if we can dump the environment variables somewhere else. I added a test but the potato machine I'm running that on is taking a very long time to run the whole thing (I did run the test in isolation with and without my patch), would you mind checking it works for you (and can we use Bash there?). Note I'm still not sure why we have env || /usr/bin/env (in case we mess with the PATH I guess?) so I've kept it. Comments welcome, I haven't coded much in Guile/Scheme.

guix shell: warning: variable 'PKG_CONFIG_PATH' is missing from shell envir=
onment
hint: One or more environment variables have a different value in the shell=
than
the one we set. This means that you may find yourself running code in an
environment different from the one you asked Guix to prepare.
This usually indicates that your shell startup files are unexpectedly
modifying those environment variables. For example, if you are using Bash,
make sure that environment variables are set or modified in
`~/.bash_profile' and _not_ in `~/.bashrc'. For more information on Bash
startup files, run:
info "(bash) Bash Startup Files"
Alternatively, you can avoid the problem by passing the `--container' or
`-C' option. That will give you a fully isolated environment running in a
"container", immune to the issue described above.

As you can see, nothing good is happening when the code parses this
later on:

=2D-8<---------------cut here---------------end--------------->8---
Although I'm sure you see it, for clarity I will explain why the above
is bad: The first variable was actually just the entire script being
echoed back; it is not actually an environment variable. The second
variable "$ PS1" is also not really an environment variable. And the
variable "\x1b[?2004l\rPKG_CONFIG_PATH", again, appears to contain
garbage at the start, probably from my PS1 value.
Basically, I think we can work around these issues if we just read and
discard all that junk at the start. I wasn't able to figure out a
graceful way to force that to happen, but I did find that simply
printing a few lines at the start of the script was good enough to work
around the issue on my computer. Here's my proposed patch, with
debugging statements included:

Subject: [PATCH] environment: Prevent PS1 from clobbering output in 'check'.
Fixes: <https://issues.guix.gnu.org/51466>.
* guix/scripts/environment.scm (child-shell-environment): In the script
executed the child shell, set PS1 to an empty value and then echo three
sentinel lines to try to "flush" the original PS1 value before printing the
environment variables. In the parent process, read and discard all lines up
to and including the last sentinel line. After that, read the remaining li=
nes
as usual.

Hi,
I also observed this bug and reported it as 53355. I tried to search
for bugs, but I didn't find this bug report until Ludo mentioned it. I
think it's probably the same bug, so I've merged them.
Ludovic Court=C3=A8s <ludo@HIDDEN> writes:

Yes, it's also Debian. Debian Bullseye. I've also verified that
similar behavior occurs on Fedora, although the problematic env vars are
different. I tried fiddling with SHELL like Vagrant did, but I couldn't
make the error go away like he did. Maybe I did something differently.
> Could you try the debugging tricks I proposed there?
Sure thing! Thank you for taking the time to make the patch, even
though it was simple. Here is the result on my Debian Bullseye ppc64el
system:

guix shell: warning: variable 'LIBRARY_PATH' is missing from shell environm=
ent
hint: One or more environment variables have a different value in the shell=
than
the one we set. This means that you may find yourself running code in an
environment different from the one you asked Guix to prepare.
This usually indicates that your shell startup files are unexpectedly
modifying those environment variables. For example, if you are using Bash,
make sure that environment variables are set or modified in
`~/.bash_profile' and _not_ in `~/.bashrc'. For more information on Bash
startup files, run:
info "(bash) Bash Startup Files"
Alternatively, you can avoid the problem by passing the `--container' or
`-C' option. That will give you a fully isolated environment running in a
"container", immune to the issue described above.

The presence of the "$" in front of LIBRARY_PATH seems suspicious:
;;; (variable "$ LIBRARY_PATH=3D/gnu/store/hvcq6yjfjjc7060pq09zm1rj02mivg=

I'm not sure why the "$" is being added. I tried various things to
remove it. I tried explicitly setting PS1 to an empty string in my
~/.bashrc. I also tried setting it explicitly to an empty string in
/etc/profile. Maybe if we can figure out where that "$ " prefix is
coming from, we can resolve this issue?

Yes, =E2=80=98--check=E2=80=99 runs $SHELL.
To make sure, could you try with the attached patch to see exactly which
variables =E2=80=98guix shell=E2=80=99 =E2=80=9Csees=E2=80=9D, and whether =
it drops a line it shouldn=E2=80=99t
drop?
TIA,

vagrant@vagranttdgxbookworm:~$ guix describe
Generation 7 Oct 28 2021 11:04:25 (current)
guix 0e6470b
repository URL: /home/vagrant/src/guix
branch: master
commit: 0e6470b47f00470c213fbf20bddc5bcf1e2f8e2a
Most things seem to work fine, but noticed an oddity with guix shell:
vagrant@vagranttdgxbookworm:~$ guix shell --pure --check --development guix guix git less
guix shell: checking the environment variables visible from shell
'/bin/bash'...
guix shell: warning: variable 'PKG_CONFIG_PATH' is missing from shell
environment
hint: One or more environment variables have a different value in the
shell than the one we set. This means that you may find yourself
running code in an environment different from the one you asked Guix to
prepare.
This usually indicates that your shell startup files are unexpectedly
modifying those environment variables. For example, if you
are using Bash, make sure that environment variables are set or modified
in `~/.bash_profile' and _not_ in `~/.bashrc'. For more
information on Bash startup files, run:
info "(bash) Bash Startup Files"
Alternatively, you can avoid the problem by passing the `--container' or
`-C' option. That will give you a fully isolated
environment running in a "container", immune to the issue described
above.
vagrant@vagranttdgxbookworm:~$ guix shell --pure --development guix guix git less
vagrant@vagranttdgxbookworm:~$ echo $PKG_CONFIG_PATH
/gnu/store/9vk59alg27y0cp1za91nfdjiy718cn1f-profile/lib/pkgconfig
So, --check seems to think the environment variable is missing but
running without --check the variable is defined...
I don't see anything obviously relevent in /etc/profile/ or
/etc/profile.d/guix.sh or /etc/profile.d/bash-completions.sh or
~/.profile or ~/.bashrc ... just used the defaults that shipped in
Debian.
live well,
vagrant
