81I often get asked about this, and I think, no, they didn't cause extra
82bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
83that the urxvt binary is larger (due to some encoding tables always being
84compiled in), but it actually uses less memory (RSS) after startup. Even
85with <code>--disable-everything</code>, this comparison is a bit unfair, as many
86features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
87already in use in this mode.

96<p>When you <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (which _is_ unfair, as this involves xft
97and full locale/XIM support which are quite bloaty inside libX11 and my
98libc), the two diverge, but not unreasnobaly so.</p>

105</dd>
106<dd>
107<p>The very large size of the text section is explained by the east-asian
108encoding tables, which, if unused, take up disk space but nothing else
109and can be compiled out unless you rely on X11 core fonts that use those
110encodings. The BSS size comes from the 64k emergency buffer that my c++
111compiler allocates (but of course doesn't use unless you are out of
112memory). Also, using an xft font instead of a core font immediately adds a
113few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
114not used.</p>
115</dd>
116<dd>
117<p>Of course, due to every character using two or four bytes instead of one,
118a large scrollback buffer will ultimately make rxvt-unicode use more
119memory.</p>
120</dd>
121<dd>
122<p>Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
123still fares rather well. And compared to some monsters like gnome-terminal
124(21152k + extra 4204k in separate processes) or konsole (22200k + extra
12543180k in daemons that stay around after exit, plus half aminute of
126startup time, including the hundreds of warnings it spits out), it fares
127extremely well *g*.</p>

130<dt><strong><a name="item_why_c_2b_2b_2c_isn_27t_that_unportable_2fbloated_2">Why C++, isn't that unportable/bloated/uncool?</a></strong><br />
131</dt>
132<dd>
133Is this a question? :) It comes up very often. The simple answer is: I had
134to write it, and C++ allowed me to write and maintain it in a fraction
135of the time and effort (which is a scarce resource for me). Put even
136shorter: It simply wouldn't exist without C++.
137</dd>
138<dd>
139<p>My personal stance on this is that C++ is less portable than C, but in
140the case of rxvt-unicode this hardly matters, as its portability limits
141are defined by things like X11, pseudo terminals, locale support and unix
142domain sockets, which are all less portable than C++ itself.</p>
143</dd>
144<dd>
145<p>Regarding the bloat, see the above question: It's easy to write programs
146in C that use gobs of memory, an certainly possible to write programs in
147C++ that don't. C++ also often comes with large libraries, but this is
148not necessarily the case with GCC. Here is what rxvt links against on my
149system with a minimal config:</p>

176<dd>
177rxvt-unicode does not directly support tabs. It will work fine with
178tabbing functionality of many window managers or similar tabbing programs,
179and its embedding-features allow it to be embedded into other programs,
180as witnessed by <em>doc/rxvt-tabbed</em> or the upcoming <code>Gtk2::URxvt</code> perl
181module, which features a tabbed urxvt (murxvt) terminal as an example
182embedding application.

215<dd>
216You should build one binary with the default options. <em>configure</em>
217now enables most useful options, and the trend goes to making them
218runtime-switchable, too, so there is usually no drawback to enbaling them,
219except higher disk and possibly memory usage. The perl interpreter should
220be enabled, as important functionality (menus, selection, likely more in
221the future) depends on it.
222</dd>
223<dd>
224<p>You should not overwrite the <code>perl-ext-common</code> snd <code>perl-ext</code> resources
225system-wide (except maybe with <code>defaults</code>). This will result in useful
226behaviour. If your distribution aims at low memory, add an empty
227<code>perl-ext-common</code> resource to the app-defaults file. This will keep the
228perl interpreter disabled until the user enables it.</p>
229</dd>
230<dd>
231<p>If you can/want build more binaries, I recommend building a minimal
232one with <code>--disable-everything</code> (very useful) and a maximal one with
233<a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (less useful, it will be very big due to a lot of
234encodings built-in that increase download times and are rarely used).</p>

237<dt><strong><a name="item_i_need_to_make_it_setuid_2fsetgid_to_support_utmp_">I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?</a></strong><br />
238</dt>
239<dd>
240Likely not. While I honestly try to make it secure, and am probably
241not bad at it, I think it is simply unreasonable to expect all of
242freetype + fontconfig + xft + xlib + ... + rxvt-unicode itself to all be
243secure. Also, rxvt-unicode disables some options when it detects that it
244runs setuid or setgid, which is not nice.
245</dd>
246<dd>
247<p>Elevated privileges are only required for utmp and pty operations on some
248systems (for example, GNU/Linux doesn't need any extra privileges for
249ptys, but some need it for utmp support). If rxvt-unicode doesn't support
250the library/setuid helper that your OS needs I'll be happy to assist you
251in implementing support for it.</p>
252</dd>
253<dd>
254<p>So, while setuid/setgid operation is supported and not a problem on your
255typical single-user-no-other-logins unix desktop, always remember that
256its an awful lot of code, most of which isn't checked for security issues
257regularly.</p>
