Guitarix 0.33.0, as of Guix commit 3c3e697, builds
non-deterministically:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix challenge guitarix

--8<---------------cut here---------------end--------------->8---

It appears to create libgxw.so either as a symlink or as a regular file
in a non-deterministic fashion.

It would be nice to see why this happens, and whether this affects all
Waf-based packages.

Hi Ludo,

You reported this bug more than 4 years ago about Guitarix 0.33 and
now it is gone and replaced by Guitarix 0.38.

From my test with Guix d258d9c7d222e6b64531c14293f41bd8d62ea4f7,
"guix challenge guitarix" and "guix build --rounds=3" do not report
issues about reproducibility.

And from my knowledge, the waf-based packages are not affected.

Do you agree to close this bug since it is not relevant anymore?

Thanks in advance for any comments.


All the best,
simon

If you’ve checked that a local build gives the same result several times
in a row (make sure it actually rebuilt things; “guix build --rounds=3
foo” does nothing if “foo” is already in the store), then you can
definitely close it!

Thanks,
Ludo’.

I think I did but how do you do that cleanly?



I am testing with "brute force" method: "guix gc -C" then proceed. I
notice unexpected behaviour; not sure it is the right place to report.


1. The first issue is that the two following commands do not populate
the same way.

(Because my machine is not very powerful, before building I populate
the store with the dependencies from substitutes.)

--8<---------------cut here---------------start------------->8---
$ guix environment guitarix -- echo Done
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------start------------->8---
$ guix build `guix show guitarix | recsel -R dependencies`
--8<---------------cut here---------------start------------->8---

The main issue is about `gettext-minimal`.

(Below, I pinpoint with star (*) which is not common between the both
commands and with sharp (#) which appears twice in the same list.)


2. The second issue is the inconsistent outputs:

--8<---------------cut here---------------start------------->8---
$ guix build guitarix --no-substitutes --dry-run

--8<---------------cut here---------------start------------->8---


Why `ghostscript` is downloaded and not reported; neither by the two
populating commands?
Do I miss the obvious?

So I add it to the store with "guix build ghostscript" then I run
again "guix build guitarix --no-substitutes" and again pieces are
missing:

--8<---------------cut here---------------start------------->8---
[...]
 downloading from
http://downloads.sourceforge.net/project/cunit/CUnit/2.1-3/CUnit-2.1-3.tar.bz2
[...]
 downloading from https://c-ares.haxx.se/download/c-ares-1.15.0.tar.gz
[...]
 downloading from http://www.digip.org/jansson/releases/jansson-2.12.tar.bz2
--8<---------------cut here---------------start------------->8---


Then other pieces are missing. I suppose it is related to BAG and
depth of the dependencies.


Therefore, how is it possible to check the reproducibility of a
package without compiling the World? For example, the test suite of
Git kills my desktop machine. :-)



Thank you in advance.
simon

I would probably do “guix build guitarix” (get the substitute) and then
“guix build guitarix --check --no-grafts -K”, possibly several times*,
which builds guitarix alone from source.

(*) ‘--rounds’ is ignored when combined with ‘--check’, go figure…

That should work.

That gives a different result because ‘dependencies’ does not show
implicit inputs.

This is because of grafts, which lead to a poor UX as things are…

Perhaps there are genuine issues described in the rest of your message
but we’d need to isolate them first.  :-)

Thanks,

Yes, first things first. :-)
And I will open discussion elsewhere because it is not related to this bug.

Dear,

Resume:
The command "guix build guitarix" downloads from ci.guix.gnu.org.
Then "guix build guitarix --no-grafts -K --check" rebuilds locally.
The two differ of one symlink.

--8<---------------cut here---------------start------------->8---
diff -r --no-dereference

--8<---------------cut here---------------end--------------->8---


Inspect:

After more than 10 attempts to reproduce the behaviour where the plain
binary is replaced by the symlink, it never happens locally, so I
conclude that the bug is really hard to track. Kind of bad luck. :-)


My intuition is: the non-determinism comes from the WAF configuration
files (./waf or wscript or wafadmin/).

The process conditionally enters in functions such as "do_install" or
"symlink_as", so maybe something is hidden by Python module "os" or
similar. Moreover, note that wscript:l.990 "add_group()" is used after
"add_subdirs('libgxw/gxw')".


Basically, the output of "--check" is:

--8<---------------cut here---------------start------------->8---

Here the step (3rd *) "symlink
/gnu/store/...-guitarix-0.38.1/lib/libgxw.so (-> libgxw.so.0.1)" is
overridden by the next one "installing
build/default/libgxw/gxw/libgxw.so as
/gnu/store/...-guitarix-0.38.1/lib/libgxw.so".


Replaying with "guix environment guitarix" then from
"/tmp/guix-build-guitarix-0.38.1.drv-0", the classical "./waf
configure --prefix=install" and "./waf build" "./waf install". In this
case, one symlink is not done and the other one is overriden by the
next step.

Interestingly, the 3 last-last evaluations by Cuirass is of the kind "--check".

https://ci.guix.gnu.org/build/1818089/details
https://ci.guix.gnu.org/build/1871705/details
https://ci.guix.gnu.org/build/1903552/details

Therefore, if we were comparing on November 3rd, we would conclude
differently. ;-)


However, the last evaluation is creating the symlink without overriding it.

Well, even this bug is annoying speaking about reproducibility --
because it it not the *exact* same installation -- it is mitigated by
the fact that the same binary is symlinked or not. I will revisit this
bug when WAF will fully use Python 3.


All the best,

My intuition :-) is that waf traverses files using directly
opendir/readdir, which returns files in an order that’s file
system-dependent.  That, in turn, leads it to make .so a symlink or not
in a non-deterministic fashion.

So I would suggest looking for uses of ‘readdir’ (or anything equivalent
in Python).

It would also be worth checking what others involved in the Reproducible
Builds effort have done (Debian, openSuSE, etc.).

Thanks,
Ludo’.

Yes, it should come from the function 'os.listdir' (readdir). The
documentation [1] says: "The list is in arbitrary order."

[1] https://docs.python.org/2/library/os.html#os.listdir


The function 'os.listdir' is called some times ;-)

--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------end--------------->8---

And do not talk about the function 'walk' which internally use 'listdir'. :-)


I have no idea how to address this issue.

Lot of sun for Debian [2] ;-)
I mean from what I understand, they do not find any reproducibility
issue and they apply only this patch [3].

[2] https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/guitarix.html
[3] https://sources.debian.org/patches/guitarix/0.36.1-1/02-libdl.patch/


Do not know about openSuSE.

Hmm.

BTW, did you try comparing both build logs, in particular the lines
corresponding to the creation of the offending .so file?  That might
help narrow the search space.

Also, we can play with disorderfs to perhaps reproduce the problem
locally and be in more favorable debugging conditions.

Guitarix has been updated to 0.41.0 by commit
bf592ef506e1db0340dc11faa0514fe80793e6d6.

I have tried "guix build guitarix --no-grafts --check -K" at least 10
times without noticing an unreproducible behaviour.

Could someone confirm this and then close this almost 5 years old bug?

I propose to open another bug report to track the waf-based packages issues.


All the best,
simon

Confirmed!

This sounds reasonable, given this is 5 years old and perhaps not
relevant anymore.

Closing, thank you!
