22FREQUENTLY ASKED QUESTIONS 22FREQUENTLY 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.

24 The version number is displayed with the usage (-h). Also the escape 107 The version number is displayed with the usage (-h). Also the escape
25 sequence "ESC [ 8 n" sets the window title to the version number. 108 sequence "ESC [ 8 n" sets the window title to the version number.

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.
