Description Milan Crha 2021-06-10 08:45:02 UTC
Okay, the summary is not accurate, I can remove it, but it takes some core things together with it, which is something unexpected. For example I really do not want to remove binutils, neither fedora-packager, nor gcc or vala.

Is that really such a core package, that it cannot be removed on its own?

Is this ok [y/N]:

Comment 1 Milan Crha 2021-06-10 08:51:30 UTC
Note this is Fedora 34. Funny part is, the "How to test" of the Fedora 35 change [1] starts with "install the package", but if the core parts of the system require it, is there a way to *not* have it installed everywhere?

In any case, the most confusing thing for me is it's named *...-client*, which invokes for me that it can be uninstalled on its own, when I'm not interested in the *client* functionality.

[1] https://fedoraproject.org/wiki/Changes/DebuginfodByDefault#How_To_Test

Comment 2 Frank Ch. Eigler 2021-06-10 10:24:40 UTC
Thanks for the report.  We are discussing this also in context of bug #1947876.  I tweaked the Changes page to point out that rpm installation is already done.

Until the time when/if these RPM dependencies are tweaked, uninstalling this package is not the best way of not using it.  Rather do that by keeping $DEBUGINFOD_URLS unset or empty.  See also https://fedoraproject.org/wiki/Debuginfod .

I propose closing this as NOTABUG.

Comment 3 Milan Crha 2021-06-10 11:49:30 UTC
(In reply to Frank Ch. Eigler from comment #2)
> uninstalling this package is not the best way of not using it.

Why not? The uninstall should make sure nothing is doing things I do not want it to do (I really do not want to auto-download 600+MB of the WebKitGTK package debuginfo, which unpacks to more than 2GB, on my relatively slow network (not talking about metered networks, whch you might have covered, I believe)).

> Rather do that by keeping $DEBUGINFOD_URLS unset or empty.

I thought that too, but the change page is sparse on how to do that "for all users and all processes". I checked the /etc/profile.d/ and saw there the new files, which are run I do not know when (their content is also suspicious [1], but it's another story) and then gave up. I want to have it disabled for sure and all processes, not for processes run in terminal being disabled, but those ran by D-Bus not being disabled. The ABRT daemon should also be covered (it calls gdb).


[1] `if [ -n "https://debuginfod.fedoraproject.org/" ]; then` always evaluates to true, the same as
    `if ("https://debuginfod.fedoraproject.org/" != "") then`, thus I miss the idea behind these lines

Comment 5 Mark Wielaard 2021-06-10 13:00:03 UTC
The reason is that you seem to want to keep binutils, which has a hard requirement on libdebuginfod.so.1.
If this really bothers you then you might want to request the binutils package try to turn that into a soft dependency (Recommends) by dynamically loading libdebuginfod.so.1 when available.

Comment 6 Milan Crha 2021-06-10 13:04:56 UTC
Aha, thanks. I tried to find out what brings the lengthy list, but I failed. Let's move this to binutils then.

Comment 7 Frank Ch. Eigler 2021-06-10 13:16:11 UTC
This is not a binutils bug either.  Many other packages link to libdebuginfod too.

If what you're really asking for is an easier systemwide way to disable this function than per-user environment variables, then let's deal with that here in elfutils land.

Comment 8 Milan Crha 2021-06-10 13:21:30 UTC

Correct.

An uninstall was a natural option, but it failed under the hood. I can probably remove the /etc/profile.d/ files, but those would get back on a version update. Having there a specific package for the default functionality on/off (installed => on, not installed => off), which the -client subpackage looked like a good candidate for, then even better.

Comment 9 Frank Ch. Eigler 2021-06-10 13:29:11 UTC

Comment 10 Milan Crha 2021-06-10 14:05:20 UTC
> That way a local admin can remove or update or add more files.

As I'm mostly interested to disable this and do not be surprised that some package added and reenabled the behavior any time later, I do not see how that can be achieved.

Comment 11 Frank Ch. Eigler 2021-06-10 14:12:22 UTC
> I do not see how that can be achieved.

Some combination of clever rpm %config or %ghost properties should handle the reasonably foreseeable cases.

Comment 12 Milan Crha 2021-06-10 14:23:57 UTC
I meant by the user, by me, effectively not knowing which all packages can install the files and how they are named.

Simply to have a global (per user?) on/off, regardless what will be installed or uninstalled after the setting is done.

From what I understood so far, to have the variable in /etc/environment will not help right now, because the /etc/profile.d/ file will set the variable anyway, right? I can add it into ~/.bashrc, but even that is not the right thing for the D-Bus system (not session) processes, or even for gdm.

Comment 13 Frank Ch. Eigler 2021-06-10 14:37:08 UTC
I believe that the programs that would import the environment variable settings via /etc/profile.d/* are the same programs (login shells) that would immediately import overrides from a $HOME/.profile or eqv.

Comment 14 Milan Crha 2021-06-10 15:27:43 UTC
Hrm, I tried this on an up-to-date rawhide machine. My ~/.profile contains only a single line:

   export DEBUGINFOD_URLS=xxx

When I log out and log in again and open a terminal I see this:

   set | grep URL
   DEBUGINFOD_URLS='xxx https://debuginfod.fedoraproject.org/ https://debuginfod.fedoraproject.org/'

Which shows it doesn't work (and it has the URL really twice there, no idea why). My value did not override the one in the profile.d, it had been added to the list. I didn't find a man page for that .profile file, one close thing is [1], where is said the ~/.profile overrides things from /etc/profile.

When I add the same export to the ~/.bashrc then it does override the value.

[1] https://www.ibm.com/docs/en/zos/2.4.0?topic=shell-customizing-homeprofile

Comment 15 Frank Ch. Eigler 2021-06-10 16:12:19 UTC
OK, noted the .bashrc file as an appropriate place for overriding the system profile defaults.

https://fedoraproject.org/wiki/Debuginfod#Disabling

I think there is still a need to have a systemwide file-drop-in gadget like the elfutils RFE describes.

Comment 16 Milan Crha 2021-06-10 16:18:01 UTC
Right, admins may want to override it for all users, at a single place. I'm unsure how that would work for random packages trying to add their own debuginfo sites.

One might even sneak in and add their server just to check which machines are looking for what debuginfo packages, which is something privacy sensitive users might not like at all. But that had been discussed elsewhere in lengthy, no need to open that question here ;)

Comment 17 Milan Crha 2021-06-11 05:24:42 UTC
I just filled bug #1970741, which is partly related to this issue, but it's only about the environment variable, thus I rather split it to a separate report.

I like that idea, but I think it is independent from documenting how to en/disable the DEBUGINFOD_URLS in the user enviroment.
Is there anything more to do for this bug? It seems it is now properly documented.

Comment 19 Milan Crha 2021-06-14 10:09:57 UTC
I still believe the best option is to be able to uninstall the `-client` subpackage, thus it's obvious there will be no search, but if you think the doc update is enough, then feel free to close this bug.

Comment 20 Frank Ch. Eigler 2021-10-13 14:35:08 UTC
The next upstream release of elfutils will use /etc/debuginfod/*.urls drop-in files to load the default $DEBUGINFOD_URLS path.  To disable a systemwide default, just remove or rename any files the distro put there.

That means you have root access on the machine. Similarly as when I tried to uninstall the "client" subpackage.

Does the new method work with `unset DEBUGINFOD_URLS` in ~/.bashrc file, or I should develop a new way of not wanting to download gigabytes of debug info when trying to catch a backtrace of a running application?

By the way, supposing the files will be provided by certain package, when I remove the files and that package will be updated, then the files will be "returned back" by that update, right?

Yes, if you want to make systemwide changes, you need systemwide privileges.

> Does the new method work with `unset DEBUGINFOD_URLS` in ~/.bashrc file,

Yes.

Look into setting $DEBUGINFOD_MAXTIME and $DEBUGINFOD_MAXSIZE also, coming
soon in elfutils 0.186.

Possibly, depending on exact rpm flags.  So you could edit the file (to clear out its contents); then RPM should preserve it like any other changed config file.
