1 | CAUTION: This patch compiles, but is otherwise totally untested! |
2 | ||
3 | This patch also implements --times-only. | |
4 | ||
5 | Implementation details for the --source-filter and -dest-filter options: | |
6 | ||
7 | - These options open a *HUGE* security hole in daemon mode unless they | |
8 | are refused in your rsyncd.conf! | |
9 | ||
10 | - Filtering disables rsync alogrithm. (This should be fixed.) | |
11 | ||
12 | - Source filter makes temporary files in /tmp. (Should be overridable.) | |
13 | ||
14 | - If source filter fails, data is send unfiltered. (Should be changed | |
15 | to abort.) | |
16 | ||
17 | - Failure of destination filter, causes data loss!!! (Should be changed | |
18 | to abort.) | |
19 | ||
20 | - If filter changes size of file, you should use --times-only option to | |
21 | prevent repeated transfers of unchanged files. | |
22 | ||
23 | - If the COMMAND contains single quotes, option-passing breaks. (Needs | |
24 | to be fixed.) | |

359 | +Use of --source-filter automatically enables --whole-file. | |
360 | +If your filter does not output the same number of bytes that it received on | |
361 | +input, you should use --times-only to disable size and content checks on | |
362 | +subsequent rsync runs. | |

364 | +dit(bf(--dest-filter=COMMAND)) This option allows you to specify a filter | |
365 | +program that will be applied to the contents of all transferred regular | |
366 | +files before the data is written to disk. COMMAND will receive the data on | |
367 | +its standard input and it should write the filtered data to standard | |
368 | +output. COMMAND should exit non-zero if it cannot process the data or if | |
369 | +it encounters an error when writing the data to stdout. | |

377 | dit(bf(--protocol=NUM)) Force an older protocol version to be used. This | |
378 | is useful for creating a batch file that is compatible with an older | |
