gio (part of glib2.tcz) shows gnutls-related warning

[GNUser]

Code: [Select]

$ gio info <any_binary_file>
/usr/local/lib/libgnutls.so.30: version `GNUTLS_3_7_4' not found (required by /usr/local/lib/gio/modules/libgiognutls.so)
Failed to load module: /usr/local/lib/gio/modules/libgiognutls.so
...I just noticed this today. I think it's new with TCL15 x86_64.

[GNUser]

The error occurred when I was compiling something and had a lot of extensions loaded. When I boot using my usual (very minimal) onboot.lst, the error does not occur. Strange.

[Rich]

Hi GNUser
Do you have both  gnutls35.tcz  and  gnutls38.tcz  in your
tce directory?

[GNUser]

Hi Rich. Yes, and both of them are loaded:

Code: [Select]

$ tce-status -i | grep tls
gnutls35
gnutls38I'm not getting the error right now.

Both of these extensions were also loaded at the time I was getting the error.

[GNUser]

If I load gtk3-dev.tcz, the error shows up again.

On my system, these are the additional extensions that are loaded when I load gtk3-dev, so the culprit has to be one of these:

Code: [Select]

$ tce-load -wil gtk3-dev
gtk3-dev is already downloaded.

/usr/local/lib/libgnutls.so.30: version `GNUTLS_3_7_4' not found (required by /usr/local/lib/gio/modules/libgiognutls.so)

[GNUser]

I narrowed it down to glib-networking.tcz. When it is loaded, I get the error.

[GNUser]

glib-networking.tcz is the culprit. Error happens if glib-networking is loaded and /usr/local/lib/libgnutls.so.30 points to gnutls35:

Code: [Select]

$ ls -l /usr/local/lib/libgnutls.so.30
lrwxrwxrwx    1 root     root            50 May 10 20:58 /usr/local/lib/libgnutls.so.30 -> /tmp/tcloop/gnutls35/usr/local/lib/libgnutls.so.30
$ gio info test.txt

Failed to load module: /usr/local/lib/gio/modules/libgiognutls.so
If glib-networking is loaded and /usr/local/lib/libgnutls.so.30 points to gnutls38, there is no error:

Code: [Select]

$ sudo rm /usr/local/lib/libgnutls.so.30
$ sudo ln -s /tmp/tcloop/gnutls38/usr/local/lib/libgnutls.so.30 /usr/local/lib/libgnutls.so.30
$ gio info test.txt
-> no errorMy suggestion is for glib-networking.tcz to have a startup script that makes sure libgnutls.so.30 is pointing to gnutls38.

EDIT: It seems this is another example of an unintentional abi breakage between library versions with same major version number (similar to the ncurses issue).

[Rich]

Hi GNUser

I narrowed it down to glib-networking.tcz. When it is loaded, I get the error.

Well yeah. That's because it depends on seeing the correct version of libgnutls.so.

gnutls35.tcz contains:

Code: [Select]

/usr/local/lib/libgnutls.so
/usr/local/lib/libgnutls.so.30
/usr/local/lib/libgnutls.so.30.26.2
gnutls38.tcz contains:

Code: [Select]

/usr/local/lib/libgnutls.so
/usr/local/lib/libgnutls.so.30
/usr/local/lib/libgnutls.so.30.37.1
The dependency file for glib-networking.tcz lists gnutls38.tcz.
It's probably finding libgnutls.so from gnutls35.tcz.
Try swapping the load order for gnutls35.tcz and gnutls38.tcz.

[GNUser]

Try swapping the load order for gnutls35.tcz and gnutls38.tcz.

I don't load either extension manually--they are both brought in as dependencies. To swap the order I'd have to go through every extension that I load, figure out which ones bring in gnutls35 vs. gnutls38, and arrange my onboot.lst accordingly. This is too much work. (Plus I'd have to remember this issue any time in the future that I want to try a new extension with gnutls in the dependency tree.)

If a startup script in glib-networking is not the way to go, let's just let it go. I'll deal with this breakage when I bump into it.

[Rich]

Hi GNUser
Add  gnutls38.tcz  to the beginning of your onboot.lst file.
See if any extensions that depend on  gnutls35.tcz  complain.
I'm hoping maybe  gnutls38.tcz  is backward compatible.

If it helps, the following have some dependency on  gnutls35.tcz.
I filtered out the -dev.tcz extensions to keep the lister shorter:

Add  gnutls38.tcz  to the beginning of your onboot.lst file.

That's a nice idea, thank you. It solves the problem without adding complexity to the system or a burden to my memory.

See if any extensions that depend on  gnutls35.tcz  complain.

None so far.

I'm hoping maybe  gnutls38.tcz  is backward compatible.

It seems so. Which raises an obvious question: If it turns out that gnutls38 is completely backward compatible, why do we need both gnutls35 and gnutls38 in the repo? It would be simpler to:

1. rename gnutls38.tcz to gnutls.tcz, rename gnutls38-dev.tcz to gnutls-dev.tcz
2. remove gnutls35.tcz and gnutls35-dev.tcz from the repo
3. make sure all .dep files that contain gnutls35{,-dev}.tcz or gnutls38{,-dev}.tcz are edited to contain gnutls{,-dev}.tcz

[Juanito]

gnutls38 is only semi-backwards compatible.with gnutls35.

Although both gnutls35 and gnutls38 contain libgnutls.so.30, gnutls35 contains libgnutlsxx.so.28 and gnutls38 contains libgnutlsxx.so.30. I'm not sure how many extensions have a dependency on libgnutlsxx, but there will be a problem if there are some that do.

I've been occupied with eliminating dependencies on openssl-1.1.1 and will now look again at eliminating dependencies on gnutls35 - the most pressing being libcups and libavformat.

[Rich]

Hi Juanito
Supposing gnutls38 were changed to something like this:

Code: [Select]

libgnutlsxx.so -> libgnutlsxx.so.30.0.0
libgnutlsxx.so.30 -> libgnutlsxx.so.30.0.0
libgnutlsxx.so.30.0.0
libgnutlsxx.so.28 -> libgnutlsxx.so.28.1.0
libgnutlsxx.so.28.1.0That should force the newer version when compiling and
still allow older programs to find the gnutls35 version.

[Juanito]

My feeling is that those changes would lead to confusion.

To force compiling against gnutls38, gnutls38-dev needs to be loaded before gnutls35-dev or, failing that, the rootfs symlinks to gnutls35-dev can be removed and replaced with those of gnutls38-dev.

[GNUser]

gnutls38 is only semi-backwards compatible.with gnutls35.

Although both gnutls35 and gnutls38 contain libgnutls.so.30, gnutls35 contains libgnutlsxx.so.28 and gnutls38 contains libgnutlsxx.so.30. I'm not sure how many extensions have a dependency on libgnutlsxx, but there will be a problem if there are some that do.

This is crystal clear. Thank you for the clarification.
