| Summary | 0008962: gnunet-setup fails to find libexec libraries | ||||
| Description | Hi, I'm still trying to make gnunet work on Guix, I'm starting to understand more things and I've encountered an issue caused by gnunet-gtk being in a different directory than gnunet. For context, because Guix needs reproducible builds and because gnunet and gnunet-gtk are two different packages, gnunet is built normally and installed in the /gnu/store/…-gnunet-0.21.2/. This includes the lib/gnunet/libexec directory. Similarly, gnunet-gtk is built with --with-gnunet pointing to the first package and installed in its own directory /gnu/store/…-gnunet-gtk-0.21.0/. The problem arises when gnunet-gtk tries accessing libexec binaries, for example gnunet-daemon-hostlist, it will call « GNUNET_OS_get_libexec_binary_path ("gnunet-daemon-hostlist")» (gnunet-setup-hostlist-server.c:160). This will incorrectly return gnunet-gtk's installation directory instead of the gnunet directory that contains the binaries. As a simple fix, I tried setting GNUNET_PREFIX to the gnunet directory, but this prevents gnunet-gtk from finding its own files. Should GNUNET_OS_get_libexec_binary_path be changed to return its own libexec directory instead of the caller's or is there a variable I can tweak in the packaging ? Thank you for your time, Noé Lopez | ||||
| Steps To Reproduce | Using guix: $ guix shell gnunet gnunet-setup $ touch ~/.config/gnunet.conf $ gnunet-setup then go into the hostlist tab Building from source: install gnunet in directory A configure gnunet-gtk with --with-gnunet=A install gnunet-gtk in directory B $ gnunet-setup then go into the hotlist tab, it should then error saying it doesn't find the libexec binaries | ||||

I am currently trying to use gdb to see exactly where the path finding fails |
|
|
I have found the exact cause of the issue, in the function os_get_gnunet_path(). It first tries getting the path from the GNUNET_PREFIX, but that is not possible. Then it tries from proc maps, but that returns the gnunet-setup's path, instead of gnunet-arm. This is where it returns the wrong value. After, it would have tried getting it from PATH which could work, but it returns a symbolic link's path. Lastly, it would have tried /proc/exe, but that also returns the gnunet-setup path. If I understand correctly, the two /proc functions are assuming that the caller's path is the same as the gnunet path, which is not necessarily the case as gnunet-gtk is a different package and thus might call the function from a different directory. A solution could be prioritizing checking PATH before /proc, and making sure it dereferences symbolic links. I'd be happy to provide a patch for that, or something else if there is a better solution. Thanks for your time and good night :) |

My guess is that this is actually a bug in gnunet-gtk. os_get_gnunet_path() should obviously return the path to gnunet's libexec. The logic for an application return its own libexec path should be different (potentially). We certainly did not indent that gnunet-gtk MUST be installed into the same prefix as gnunet. Unfortunately, I cannot really move this issue into the gnunet-gtk project I think, so let's keep it here. |

Yes it must be an issue with gnunet-gtk as even when changing os_get_gnunet_path() to always return the gnunet path is will fail to find other files from gnunet-gtk. So I think there are two bugs, 1) os_get_gnunet_path() fails to find the good prefix and instead returns gnunet-gtk's. 2) gnunet-gtk is looking for its own files in the gnunet prefix instead of its own. |
