| 23:13 | Fix the "add" command so that it prints "SKIP" instead of "ADDED" for files that are already under management. Code to do this was already in place, but it did not work correctly due to a logic error. ... (check-in: d252cfd6 user: drh tags: trunk) | |

48 49 50 51 52 53 54 | under analysis. For a large file that has many historical changes, this can take several seconds. For this reason, the default [/help?cmd=/annotate|/annotate] webpage only shows those lines that where changed by the 20 most recent modifications to the file. This allows the loop on step 6 to terminate after only 19 diffs instead of the hundreds or thousands of diffs that might be required for a frequently modified file. | | | > > > > | 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 | under analysis.

This allows the loop on step 6 to terminate after only 19 diffs instead of the hundreds or thousands of diffs that might be required for a frequently modified file. As currently implemented (as of 2015-12-12) the annotate algorithm does not follow files across name changes. File name change information is available in the database, and so the algorithm could be enhanced to follow files across name changes by modifications to step 3. Step 2 is interesting in that it is [/artifact/6cb824a0417?ln=196-201 | implemented] using a [https://www.sqlite.org/lang_with.html#recursivecte|recursive common table expression]. |
