Willy Tarreau | 1a52dbd | 2009-06-28 19:37:53 +0200 | [diff] [blame] | 1795 | * the list when not needed. Any analyser may return 0 |
| 1796 | * to break out of the loop, either because of missing |
| 1797 | * data to take a decision, or because it decides to |
| 1798 | * kill the session. We loop at least once through each |
| 1799 | * analyser, and we may loop again if other analysers |
| 1800 | * are added in the middle. |

| 1802 | * We build a list of analysers to run. We evaluate all |
| 1803 | * of these analysers in the order of the lower bit to |
| 1804 | * the higher bit. This ordering is very important. |
| 1805 | * An analyser will often add/remove other analysers, |
| 1806 | * including itself. Any changes to itself have no effect |
| 1807 | * on the loop. If it removes any other analysers, we |
| 1808 | * want those analysers not to be called anymore during |
| 1809 | * this loop. If it adds an analyser that is located |
| 1810 | * after itself, we want it to be scheduled for being |
| 1811 | * processed during the loop. If it adds an analyser |
| 1812 | * which is located before it, we want it to switch to |
| 1813 | * it immediately, even if it has already been called |
| 1814 | * once but removed since. |
| 1815 | * |
| 1816 | * In order to achieve this, we compare the analyser |
| 1817 | * list after the call with a copy of it before the |
| 1818 | * call. The work list is fed with analyser bits that |
| 1819 | * appeared during the call. Then we compare previous |
| 1820 | * work list with the new one, and check the bits that |
| 1821 | * appeared. If the lowest of these bits is lower than |
| 1822 | * the current bit, it means we have enabled a previous |
| 1823 | * analyser and must immediately loop again. |
