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

		109	When using the rxvtc client, the version displayed is that of the
		110	daemon.
		111
		112	I am using Debian GNU/Linux and have a problem...
		113	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		114	patches that considerably change the behaviour of rxvt-unicode.
		115	Before reporting a bug to the original rxvt-unicode author please
		116	download and install the genuine version
		117	(<http://software.schmorp.de#rxvt-unicode>) and try to reproduce the
		118	problem. If you cannot, chances are that the problems are specific
		119	to Debian GNU/Linux, in which case it should be reported via the
		120	Debian Bug Tracking System (use "reportbug" to report the bug).
		121
		122	For other problems that also affect the Debian package, you can and
		123	probably should use the Debian BTS, too, because, after all, it's
		124	also a bug in the Debian version and it serves as a reminder for
		125	other users that might encounter the same issue.
		126
		127	I am maintaining rxvt-unicode for distribution/OS XXX, any
		128	recommendation?
		129	You should build one binary with the default options. configure now
		130	enables most useful options, and the trend goes to making them
		131	runtime-switchable, too, so there is usually no drawback to enbaling
		132	them, except higher disk and possibly memory usage. The perl
		133	interpreter should be enabled, as important functionality (menus,
		134	selection, likely more in the future) depends on it.
		135
		136	You should not overwrite the "perl-ext-common" snd "perl-ext"
		137	resources system-wide (except maybe with "defaults"). This will
		138	result in useful behaviour. If your distribution aims at low memory,
		139	add an empty "perl-ext-common" resource to the app-defaults file.
		140	This will keep the perl interpreter disabled until the user enables
		141	it.
		142
		143	If you can/want build more binaries, I recommend building a minimal
		144	one with "--disable-everything" (very useful) and a maximal one with
		145	"--enable-everything" (less useful, it will be very big due to a lot
		146	of encodings built-in that increase download times and are rarely
		147	used).
		148
		149	I need to make it setuid/setgid to support utmp/ptys on my OS, is this
		150	safe?
		151	Likely not. While I honestly try to make it secure, and am probably
		152	not bad at it, I think it is simply unreasonable to expect all of
		153	freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
		154	itself to all be secure. Also, rxvt-unicode disables some options
		155	when it detects that it runs setuid or setgid, which is not nice.
		156	Besides, with the embedded perl interpreter the possibility for
		157	security problems easily multiplies.
		158
		159	Elevated privileges are only required for utmp and pty operations on
		160	some systems (for example, GNU/Linux doesn't need any extra
		161	privileges for ptys, but some need it for utmp support). It is
		162	planned to mvoe this into a forked handler process, but this is not
		163	yet done.
		164
		165	So, while setuid/setgid operation is supported and not a problem on
		166	your typical single-user-no-other-logins unix desktop, always
		167	remember that its an awful lot of code, most of which isn't checked
		168	for security issues regularly.
