29=item Isn't rxvt supposed to be small? Don't all those features bloat?
30
31I often get asked about this, and I think, no, they didn't cause extra
32bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
33that the urxvt binary is larger (due to some encoding tables always being
34compiled in), but it actually uses less memory (RSS) after startup. Even
35with C<--disable-everything>, this comparison is a bit unfair, as many
36features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
37already in use in this mode.
38

41 188985 9048 66616 18222 1788 urxvt --disable-everything
42
43When you C<--enable-everything> (which _is_ unfair, as this involves xft
44and full locale/XIM support which are quite bloaty inside libX11 and my
45libc), the two diverge, but not unreasnobaly so.
46
47 text data bss drs rss filename
48 163431 2152 24 20123 2060 rxvt --enable-everything
49 1035683 49680 66648 29096 3680 urxvt --enable-everything
50
51The very large size of the text section is explained by the east-asian
52encoding tables, which, if unused, take up disk space but nothing else
53and can be compiled out unless you rely on X11 core fonts that use those
54encodings. The BSS size comes from the 64k emergency buffer that my c++
55compiler allocates (but of course doesn't use unless you are out of
56memory). Also, using an xft font instead of a core font immediately adds a
57few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
58not used.
59
60Of course, due to every character using two or four bytes instead of one,
61a large scrollback buffer will ultimately make rxvt-unicode use more
62memory.
63
64Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
65still fares rather well. And compared to some monsters like gnome-terminal
66(21152k + extra 4204k in separate processes) or konsole (22200k + extra
6743180k in daemons that stay around after exit, plus half aminute of
68startup time, including the hundreds of warnings it spits out), it fares
69extremely well *g*.
70
71=item Why C++, isn't that unportable/bloated/uncool?
72
73Is this a question? :) It comes up very often. The simple answer is: I had
74to write it, and C++ allowed me to write and maintain it in a fraction
75of the time and effort (which is a scarce resource for me). Put even
76shorter: It simply wouldn't exist without C++.
77
78My personal stance on this is that C++ is less portable than C, but in
79the case of rxvt-unicode this hardly matters, as its portability limits
80are defined by things like X11, pseudo terminals, locale support and unix
81domain sockets, which are all less portable than C++ itself.
82
83Regarding the bloat, see the above question: It's easy to write programs
84in C that use gobs of memory, an certainly possible to write programs in
85C++ that don't. C++ also often comes with large libraries, but this is
86not necessarily the case with GCC. Here is what rxvt links against on my
87system with a minimal config:
88
89 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
90 libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
91 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
92 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
93
94And here is rxvt-unicode:
95
96 libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
97 libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
98 libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
99 libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
100 /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
101
102No large bloated libraries (of course, none were linked in statically),
103except maybe libX11 :)
104
105=item Does it support tabs, can I have a tabbed rxvt-unicode?
106
107rxvt-unicode does not directly support tabs. It will work fine with
108tabbing functionality of many window managers or similar tabbing programs,
109and its embedding-features allow it to be embedded into other programs,
110as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
111module, which features a tabbed urxvt (murxvt) terminal as an example
112embedding application.

136
137=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
138
139You should build one binary with the default options. F<configure>
140now enables most useful options, and the trend goes to making them
141runtime-switchable, too, so there is usually no drawback to enbaling them,
142except higher disk and possibly memory usage. The perl interpreter should
143be enabled, as important functionality (menus, selection, likely more in
144the future) depends on it.
145
146You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
147system-wide (except maybe with C<defaults>). This will result in useful
148behaviour. If your distribution aims at low memory, add an empty
149C<perl-ext-common> resource to the app-defaults file. This will keep the
150perl interpreter disabled until the user enables it.
151
152If you can/want build more binaries, I recommend building a minimal
153one with C<--disable-everything> (very useful) and a maximal one with
154C<--enable-everything> (less useful, it will be very big due to a lot of
155encodings built-in that increase download times and are rarely used).
156
157=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
158
159Likely not. While I honestly try to make it secure, and am probably
160not bad at it, I think it is simply unreasonable to expect all of
161freetype + fontconfig + xft + xlib + ... + rxvt-unicode itself to all be
162secure. Also, rxvt-unicode disables some options when it detects that it
163runs setuid or setgid, which is not nice.
164
165Elevated privileges are only required for utmp and pty operations on some
166systems (for example, GNU/Linux doesn't need any extra privileges for
167ptys, but some need it for utmp support). If rxvt-unicode doesn't support
168the library/setuid helper that your OS needs I'll be happy to assist you
169in implementing support for it.
170
171So, while setuid/setgid operation is supported and not a problem on your
172typical single-user-no-other-logins unix desktop, always remember that
173its an awful lot of code, most of which isn't checked for security issues
174regularly.
