121 | ## We interrupt this relatively sensible macro for an especially awful | |
122 | ## hack. The tripe server emits warnings which are often caused by lack of | |
123 | ## synchronization between two peers. These are harmless and shouldn't | |
124 | ## cause test failures. But we shouldn't just trim out all messages that | |
125 | ## look like the spurious ones: if they appear when we're not expecting | |
126 | ## them, that's bad and they should properly cause a test failure. | |
127 | ## | |
128 | ## So we use the WARN command to insert magic directives into the server's | |
129 | ## message stream. The directives begin with `WARN USER test'; remaining | |
130 | ## tokens may be as follows. | |
131 | ## | |
132 | ## PUSH Introduce a new layer of nesting. Settings between | |
133 | ## this PUSH and the matching POP will be forgotten | |
134 | ## following the POP. | |
135 | ## | |
136 | ## POP End a layer of nesting. See PUSH above. | |
137 | ## | |
138 | ## IGNORE tokens Ignore lines which begin with the tokens. | |
139 | ## | |
140 | ## Token comparison isn't done very well, but it's good enough for these | |
141 | ## purposes. | |
142 | ## | |
143 | ## We also trim out trace lines here, since it's useful to produce them for | |
144 | ## debugging purposes and changing or introducing more of them shouldn't | |
145 | ## cause failures. | |
