gcc reports:

gui.c:1795:3: error: missing initializer for field ‘padding’ of ‘GActionEntry’ {aka ‘const struct _GActionEntry’} [-Werror=missing-field-initializers] 1795 | { "shutdown", activate_action, NULL, NULL, NULL },

gui.c:1796:3: error: missing initializer for field ‘padding’ of ‘GActionEntry’ {aka ‘const struct _GActionEntry’} [-Werror=missing-field-initializers] 1796 | { "reboot", activate_action, NULL, NULL, NULL },

I've found this only now because: - this is the first time I'm building virt-p2v with GTK3, - the "shutdown_actions" array depends on USE_POPOVERS which depends on GTK3 being selected, - the "missing-field-initializers" warning (treated as an error) has recently been enabled via "-Wextra" in commit 391f9833d398 ("p2v-c.m4: elicit a stricter set of warnings from gcc", 2022-09-23). The C-language documentation for GActionEntry is silent on the "padding" array: https://docs.gtk.org/gio/struct.ActionEntry.html However, the D-language docs expose it: https://api.gtkd.org/gio.c.types.GActionEntry.html Provide the missing field initializer.

The "contrib" directory contains shell scripts and a RHEL-5 patch for building (and testing) the p2v ISO on RHEL major releases 5 through 7. Recently, we've resumed the P2V ISO preparation by adopting a Fedora 35+-based procedure, with the long term plan being the Image Builder service on RHEL-9+. Theferore the "contrib" directory is now obsolete; remove it. (The "contrib/build-p2v-iso.sh" script "blocks my way" because it references gtk2-devel, and in this series I'd like to remove gtk2 support from virt-p2v. We shouldn't be updating dead code.) Checked with "make dist maintainer-check-extra-dist".

Commit eaa5ce8b43e0 ("p2v: Break long lines when displaying virt-v2v output in GUI.", 2016-01-08) introduced *line breaking* as a workaround for a GTK2 regression, under which the handling of long lines from the virt-v2v log would slow down very much. Commit e09b955bdbbc ("p2v: Use virt-v2v --colours option, support colour in the run dialog (RHBZ#1314244).", 2016-06-18) silently changed the *line breaking* workaround into *line truncation*, also adopting a much shorter cut-off length (replacing 1024 with 256). Now, whether this logic remains useful is untestable today. That's because commit 9b057cc1ac5f ("p2v: Don't display debugging messages in the run dialog.", 2016-06-18), from the same series as the one that commit e09b955bdbbc belonged to [*], had relegated the verbose & trace messages -- IOW, all the long lines -- from the GUI to the conversion log file (except maybe the last 50 lines of a failed conversion's log). [*] https://bugzilla.redhat.com/show_bug.cgi?id=1314244#c4 Therefore, the line truncation workaround may have become effectively useless right at the end of that series, and stays most probably dead code today, regardless of the GTK version used. This is relevant because we want to remove GTK2 support from virt-p2v. Some evidence would be nice as to whether the line truncation is obsolete due to (a) GTK3 not suffering from the long line slowdown, or (b) GTK3 still having the bug, but the bug not being triggered due to commit 9b057cc1ac5f. Either way -- that is, even though this is untestable --, just remove the truncating state from the v2v message parsing automaton. The truncating state is only reachable from the normal state, and it also returns to the normal state, so the removal is not complicated. Remove the "dots" helper variable too. The (static) variable "linelen" is only consumed in the normal->truncating transition condition, so drop that one as well.

Remove GTK2 compat code. Open-code conditional compilation directives that evaluate to constant values when virt-p2v is built with GTK3. A special note regarding GTK_SPINNER (because the code does not use a version check for the spinner widget's availability): upstream GTK introduced GTK_SPINNER in commit d21700f5105c ("Bug 319607 – Add a throbber (activity widget) to GTK+", 2009-10-14), which commit was first released in version 2.19.0, and is also contained within release 3.0.0. Even within GTK3, we have multiple compatibility layers. If we only concentrated on RHEL-9+ and Fedora-35+, we could much simplify "gui-gtk3-compat.h" as well (potentially flattening the whole header file into C sources). Given that we build virt-p2v on multiple distro families, establishing a common base version for GTK3, higher than version 3.0.0, is not so simple. So preserve "gui-gtk3-compat.h" for now.
