4	FREQUENTLY ASKED QUESTIONS	22	FREQUENTLY ASKED QUESTIONS
		23	I don't like the new selection/popups/hotkeys/perl, how do I
		24	change/disable it?
		25	You can disable the perl extension completely by setting the
		26	perl-ext-common resource to the empty string, which also keeps
		27	rxvt-unicode from initialising perl, saving memory.
		28
		29	If you only want to disable specific features, you first have to
		30	identify which perl extension is responsible. For this, read the
		31	section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
		32	example, to disable the selection-popup and option-popup, specify
		33	this perl-ext-common resource:
		34
		35	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		36
		37	This will keep the default extensions, but disable the two popup
		38	extensions. Some extensions can also be configured, for example,
		39	scrollback search mode is triggered by M-s. You can move it to any
		40	other combination either by setting the searchable-scrollback
		41	resource:
		42
		43	URxvt.searchable-scrollback: CM-s
		44
		45	Isn't rxvt supposed to be small? Don't all those features bloat?
		46	I often get asked about this, and I think, no, they didn't cause
		47	extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
		48	can see that the urxvt binary is larger (due to some encoding tables
		49	always being compiled in), but it actually uses less memory (RSS)
		50	after startup. Even with "--disable-everything", this comparison is
		51	a bit unfair, as many features unique to urxvt (locale, encoding
		52	conversion, iso14755 etc.) are already in use in this mode.
		53
		54	text data bss drs rss filename
		55	98398 1664 24 15695 1824 rxvt --disable-everything
		56	188985 9048 66616 18222 1788 urxvt --disable-everything
		57
		58	When you "--enable-everything" (which _is_ unfair, as this involves
		59	xft and full locale/XIM support which are quite bloaty inside libX11
		60	and my libc), the two diverge, but not unreasnobaly so.
		61
		62	text data bss drs rss filename
		63	163431 2152 24 20123 2060 rxvt --enable-everything
		64	1035683 49680 66648 29096 3680 urxvt --enable-everything
		65
		66	The very large size of the text section is explained by the
		67	east-asian encoding tables, which, if unused, take up disk space but
		68	nothing else and can be compiled out unless you rely on X11 core
		69	fonts that use those encodings. The BSS size comes from the 64k
		70	emergency buffer that my c++ compiler allocates (but of course
		71	doesn't use unless you are out of memory). Also, using an xft font
		72	instead of a core font immediately adds a few megabytes of RSS. Xft
		73	indeed is responsible for a lot of RSS even when not used.
		74
		75	Of course, due to every character using two or four bytes instead of
		76	one, a large scrollback buffer will ultimately make rxvt-unicode use
		77	more memory.
		78
		79	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
		80	this still fares rather well. And compared to some monsters like
		81	gnome-terminal (21152k + extra 4204k in separate processes) or
		82	konsole (22200k + extra 43180k in daemons that stay around after
		83	exit, plus half a minute of startup time, including the hundreds of
		84	warnings it spits out), it fares extremely well g.
		85
		86	Why C++, isn't that unportable/bloated/uncool?
		87	Is this a question? :) It comes up very often. The simple answer is:
		88	I had to write it, and C++ allowed me to write and maintain it in a
		89	fraction of the time and effort (which is a scarce resource for me).
		90	Put even shorter: It simply wouldn't exist without C++.
		91
		92	My personal stance on this is that C++ is less portable than C, but
		93	in the case of rxvt-unicode this hardly matters, as its portability
		94	limits are defined by things like X11, pseudo terminals, locale
		95	support and unix domain sockets, which are all less portable than
		96	C++ itself.
		97
		98	Regarding the bloat, see the above question: It's easy to write
		99	programs in C that use gobs of memory, an certainly possible to
		100	write programs in C++ that don't. C++ also often comes with large
		101	libraries, but this is not necessarily the case with GCC. Here is
		102	what rxvt links against on my system with a minimal config:
		103
		104	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		105	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		106	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		107	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		108
		109	And here is rxvt-unicode:
		110
		111	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		112	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		113	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		114	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		115	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		116
		117	No large bloated libraries (of course, none were linked in
		118	statically), except maybe libX11 :)
		119
		120	Does it support tabs, can I have a tabbed rxvt-unicode?
		121	rxvt-unicode does not directly support tabs. It will work fine with
		122	tabbing functionality of many window managers or similar tabbing
		123	programs, and its embedding-features allow it to be embedded into
		124	other programs, as witnessed by doc/rxvt-tabbed or the upcoming
		125	"Gtk2::URxvt" perl module, which features a tabbed urxvt (murxvt)
		126	terminal as an example embedding application.

		131	When using the rxvtc client, the version displayed is that of the
		132	daemon.
		133
		134	I am using Debian GNU/Linux and have a problem...
		135	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		136	patches that considerably change the behaviour of rxvt-unicode.
		137	Before reporting a bug to the original rxvt-unicode author please
		138	download and install the genuine version
		139	(<http://software.schmorp.de#rxvt-unicode>) and try to reproduce the
		140	problem. If you cannot, chances are that the problems are specific
		141	to Debian GNU/Linux, in which case it should be reported via the
		142	Debian Bug Tracking System (use "reportbug" to report the bug).
		143
		144	For other problems that also affect the Debian package, you can and
		145	probably should use the Debian BTS, too, because, after all, it's
		146	also a bug in the Debian version and it serves as a reminder for
		147	other users that might encounter the same issue.
		148
		149	I am maintaining rxvt-unicode for distribution/OS XXX, any
		150	recommendation?
		151	You should build one binary with the default options. configure now
		152	enables most useful options, and the trend goes to making them
		153	runtime-switchable, too, so there is usually no drawback to enbaling
		154	them, except higher disk and possibly memory usage. The perl
		155	interpreter should be enabled, as important functionality (menus,
		156	selection, likely more in the future) depends on it.
		157
		158	You should not overwrite the "perl-ext-common" snd "perl-ext"
		159	resources system-wide (except maybe with "defaults"). This will
		160	result in useful behaviour. If your distribution aims at low memory,
		161	add an empty "perl-ext-common" resource to the app-defaults file.
		162	This will keep the perl interpreter disabled until the user enables
		163	it.
		164
		165	If you can/want build more binaries, I recommend building a minimal
		166	one with "--disable-everything" (very useful) and a maximal one with
		167	"--enable-everything" (less useful, it will be very big due to a lot
		168	of encodings built-in that increase download times and are rarely
		169	used).
		170
		171	I need to make it setuid/setgid to support utmp/ptys on my OS, is this
		172	safe?
		173	Likely not. While I honestly try to make it secure, and am probably
		174	not bad at it, I think it is simply unreasonable to expect all of
		175	freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
		176	itself to all be secure. Also, rxvt-unicode disables some options
		177	when it detects that it runs setuid or setgid, which is not nice.
		178	Besides, with the embedded perl interpreter the possibility for
		179	security problems easily multiplies.
		180
		181	Elevated privileges are only required for utmp and pty operations on
		182	some systems (for example, GNU/Linux doesn't need any extra
		183	privileges for ptys, but some need it for utmp support). It is
		184	planned to mvoe this into a forked handler process, but this is not
		185	yet done.
		186
		187	So, while setuid/setgid operation is supported and not a problem on
		188	your typical single-user-no-other-logins unix desktop, always
		189	remember that its an awful lot of code, most of which isn't checked
		190	for security issues regularly.
