111 | ||
112 | Avoids traversal. Better option than a pile of --include statements | |
113 | for people who want to generate the file list using a find(1) | |

117 | File list structure in memory |
118 | ||
119 | Rather than one big array, perhaps have a tree in memory mirroring | |
120 | the directory tree. | |
121 | ||
122 | This might make sorting much faster! (I'm not sure it's a big CPU | |
123 | problem, mind you.) | |
124 | ||
125 | It might also reduce memory use in storing repeated directory names | |
126 | -- again I'm not sure this is a problem. | |

128 | Performance |
129 | ||
130 | Traverse just one directory at a time. Tridge says it's possible. | |
a6a3c3df MP |
131 | |
132 | At the moment rsync reads the whole file list into memory at the | |
133 | start, which makes us use a lot of memory and also not pipeline | |
134 | network access as much as we could. | |
135 | ||
0e5a1f83 MP |
136 | |
137 | Handling duplicate names | |
138 | ||
b3e6c815 | 139 | We need to be careful of duplicate names getting into the file list. |
d2e9d069 MP |
140 | See clean_flist(). This could happen if multiple arguments include |
141 | the same file. Bad. | |
b3e6c815 MP |
142 | |
143 | I think duplicates are only a problem if they're both flowing | |
144 | through the pipeline at the same time. For example we might have | |
145 | updated the first occurrence after reading the checksums for the | |
146 | second. So possibly we just need to make sure that we don't have | |
147 | both in the pipeline at the same time. | |
148 | ||
149 | Possibly if we did one directory at a time that would be sufficient. | |
150 | ||
151 | Alternatively we could pre-process the arguments to make sure no | |
58379559 MP |
152 | duplicates will ever be inserted. There could be some bad cases |
153 | when we're collapsing symlinks. | |
b3e6c815 MP |
154 | |
155 | We could have a hash table. | |
156 | ||
d2e9d069 MP |
157 | The root of the problem is that we do not want more than one file |
158 | list entry referring to the same file. At first glance there are | |
159 | several ways this could happen: symlinks, hardlinks, and repeated | |
160 | names on the command line. | |
161 | ||
162 | If names are repeated on the command line, they may be present in | |
163 | different forms, perhaps by traversing directory paths in different | |
164 | ways, traversing paths including symlinks. Also we need to allow | |
165 | for expansion of globs by rsync. | |
166 | ||
167 | At the moment, clean_flist() requires having the entire file list in | |
168 | memory. Duplicate names are detected just by a string comparison. | |
169 | ||
170 | We don't need to worry about hard links causing duplicates because | |
171 | files are never updated in place. Similarly for symlinks. | |
172 | ||
173 | I think even if we're using a different symlink mode we don't need | |
174 | to worry. | |
175 | ||
0e5a1f83 MP |
176 | Unless we're really clever this will introduce a protocol |
177 | incompatibility, so we need to be able to accept the old format as | |
178 | well. | |
179 | ||
180 | ||
a6a3c3df MP |
181 | Memory accounting |
182 | ||
183 | At exit, show how much memory was used for the file list, etc. | |
184 | ||
b3e6c815 MP |
185 | Also we do a wierd exponential-growth allocation in flist.c. I'm |
186 | not sure this makes sense with modern mallocs. At any rate it will | |
187 | make us allocate a huge amount of memory for large file lists. | |
188 | ||
0e5a1f83 | 189 | |
a6a3c3df MP |
190 | Hard-link handling |
191 | ||
192 | At the moment hardlink handling is very expensive, so it's off by | |
193 | default. It does not need to be so. | |
194 | ||
0e5a1f83 MP |
195 | Since most of the solutions are rather intertwined with the file |
196 | list it is probably better to fix that first, although fixing | |
197 | hardlinks is possibly simpler. | |
198 | ||
a6a3c3df MP |
199 | We can rule out hardlinked directories since they will probably |
200 | screw us up in all kinds of ways. They simply should not be used. | |
201 | ||
202 | At the moment rsync only cares about hardlinks to regular files. I | |
203 | guess you could also use them for sockets, devices and other beasts, | |
204 | but I have not seen them. | |
205 | ||
206 | When trying to reproduce hard links, we only need to worry about | |
207 | files that have more than one name (nlinks>1 && !S_ISDIR). | |
208 | ||
209 | The basic point of this is to discover alternate names that refer to | |
210 | the same file. All operations, including creating the file and | |
211 | writing modifications to it need only to be done for the first name. | |
212 | For all later names, we just create the link and then leave it | |
213 | alone. | |
214 | ||
215 | If hard links are to be preserved: | |
216 | ||
217 | Before the generator/receiver fork, the list of files is received | |
218 | from the sender (recv_file_list), and a table for detecting hard | |
219 | links is built. | |
220 | ||
221 | The generator looks for hard links within the file list and does | |
222 | not send checksums for them, though it does send other metadata. | |
223 | ||
224 | The sender sends the device number and inode with file entries, so | |
225 | that files are uniquely identified. | |
226 | ||
227 | The receiver goes through and creates hard links (do_hard_links) | |
228 | after all data has been written, but before directory permissions | |
229 | are set. | |
230 | ||
231 | At the moment device and inum are sent as 4-byte integers, which | |
232 | will probably cause problems on large filesystems. On Linux the | |
233 | kernel uses 64-bit ino_t's internally, and people will soon have | |
234 | filesystems big enough to use them. We ought to follow NFS4 in | |
235 | using 64-bit device and inode identification, perhaps with a | |
236 | protocol version bump. | |
237 | ||
238 | Once we've seen all the names for a particular file, we no longer | |
239 | need to think about it and we can deallocate the memory. | |
240 | ||
241 | We can also have the case where there are links to a file that are | |
242 | not in the tree being transferred. There's nothing we can do about | |
243 | that. Because we rename the destination into place after writing, | |
244 | any hardlinks to the old file are always going to be orphaned. In | |
245 | fact that is almost necessary because otherwise we'd get really | |
246 | confused if we were generating checksums for one name of a file and | |
247 | modifying another. | |
248 | ||
249 | At the moment the code seems to make a whole second copy of the file | |
250 | list, which seems unnecessary. | |
251 | ||
252 | We should have a test case that exercises hard links. Since it | |
253 | might be hard to compare ./tls output where the inodes change we | |
254 | might need a little program to check whether several names refer to | |
255 | the same file. | |

257 | IPv6 | |
258 | ||
c33e3e39 MP |
259 | Implement suggestions from http://www.kame.net/newsletter/19980604/ |
260 | and ftp://ftp.iij.ad.jp/pub/RFC/rfc2553.txt | |
261 | ||
262 | If a host has multiple addresses, then listen try to connect to all | |
263 | in order until we get through. (getaddrinfo may return multiple | |
c10b0bdd | 264 | addresses.) This is kind of implemented already. |
c33e3e39 MP |
265 | |
266 | Possibly also when starting as a server we may need to listen on | |
267 | multiple passive addresses. This might be a bit harder, because we | |
268 | may need to select on all of them. Hm. | |
269 | ||
a2d2e5c0 MP |
270 | Define a syntax for IPv6 literal addresses. Since they include |
271 | colons, they tend to break most naming systems, including ours. | |
272 | Based on the HTTP IPv6 syntax, I think we should use | |
273 | ||
274 | rsync://[::1]/foo/bar | |
275 | [::1]::bar | |
276 | ||
277 | which should just take a small change to the parser code. | |

280 | Errors |
281 | ||
282 | If we hang or get SIGINT, then explain where we were up to. Perhaps | |
283 | have a static buffer that contains the current function name, or | |
284 | some kind of description of what we were trying to do. This is a | |
285 | little easier on people than needing to run strace/truss. | |
286 | ||
287 | "The dungeon collapses! You are killed." Rather than "unexpected | |
288 | eof" give a message that is more detailed if possible and also more | |
289 | helpful. | |
290 | ||
89b0a3d9 MP |
291 | If we get an error writing to a socket, then we should perhaps |
292 | continue trying to read to see if an error message comes across | |
293 | explaining why the socket is closed. I'm not sure if this would | |
294 | work, but it would certainly make our messages more helpful. | |
295 | ||
b17dd0c4 MP |
296 | What happens if a directory is missing -x attributes. Do we lose |
297 | our load? (Debian #28416) Probably fixed now, but a test case | |
298 | would be good. | |

301 | File attributes |
302 | ||
303 | Device major/minor numbers should be at least 32 bits each. See | |

305 | ||
306 | Transfer ACLs. Need to think of a standard representation. | |
307 | Probably better not to even try to convert between NT and POSIX. | |
308 | Possibly can share some code with Samba. | |

310 | Empty directories |
311 | ||
312 | With the current common --include '*/' --exclude '*' pattern, people | |
313 | can end up with many empty directories. We might avoid this by | |
314 | lazily creating such directories. | |

317 | zlib |
318 | ||
c6e27b60 MP |
319 | Perhaps don't use our own zlib. |
320 | ||
321 | Advantages: | |
322 | ||
323 | - will automatically be up to date with bugfixes in zlib | |
324 | ||
325 | - can leave it out for small rsync on e.g. recovery disks | |
326 | ||
327 | - can use a shared library | |
328 | ||
329 | - avoids people breaking rsync by trying to do this themselves and | |
330 | messing up | |
331 | ||
332 | Should we ship zlib for systems that don't have it, or require | |
333 | people to install it separately? | |
334 | ||
335 | Apparently this will make us incompatible with versions of rsync | |
336 | that use the patched version of rsync. Probably the simplest way to | |
337 | do this is to just disable gzip (with a warning) when talking to old | |
338 | versions. | |
339 | ||
28a69e25 MP |
340 | |
341 | logging | |
342 | ||
343 | Perhaps flush stdout after each filename, so that people trying to | |
344 | monitor progress in a log file can do so more easily. See | |
345 | http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=48108 | |

349 | ||

350 | If a child of the rsync daemon dies with a signal, we should notice |
351 | that when we reap it and log a message. | |

353 | Keep stderr and stdout properly separated (Debian #23626) |
354 | ||
6479c2ed MP |
355 | Use a separate function for reporting errors; prefix it with |
356 | "rsync:" or "rsync(remote)", or perhaps even "rsync(local | |
357 | generator): ". | |
358 | ||

360 | proxy authentication |
361 | ||
362 | Allow RSYNC_PROXY to be http://user:pass@proxy.foo:3128/, and do | |
363 | HTTP Basic Proxy-Authentication. | |
364 | ||
365 | Multiple schemes are possible, up to and including the insanity that | |
366 | is NTLM, but Basic probably covers most cases. | |
367 | ||
368 | SOCKS | |
369 | ||
370 | Add --with-socks, and then perhaps a command-line option to put them | |
371 | on or off. This might be more reliable than LD_PRELOAD hacks. | |
372 | ||
27741d9f MP |
373 | Better statistics: |
374 | ||
375 | <Rasmus> mbp: hey, how about an rsync option that just gives you the | |
376 | summary without the list of files? And perhaps gives more | |
377 | information like the number of new files, number of changed, | |
378 | deleted, etc. ? | |
379 | <mbp> Rasmus: nice idea | |
380 | <mbp> there is --stats | |
381 | <mbp> but at the moment it's very tridge-oriented | |
382 | <mbp> rather than user-friendly | |
383 | <mbp> it would be nice to improve it | |
384 | <mbp> that would also work well with --dryrun | |

386 | TDB: |
387 | ||
388 | Rather than storing the file list in memory, store it in a TDB. | |
389 | ||
390 | This *might* make memory usage lower while building the file list. | |
391 | ||
392 | Hashtable lookup will mean files are not transmitted in order, | |
393 | though... hm. | |
394 | ||
395 | This would neatly eliminate one of the major post-fork shared data | |
396 | structures. | |

407 | I think that would be good too. For example, people uploading files | |
408 | to a web server might like to say | |
409 | ||
410 | rsync -avzP --chmod a+rX ./ sourcefrog.net:/home/www/sourcefrog/ | |
411 | ||
412 | Ideally the patch would implement as many of the gnu chmod semantics | |
413 | as possible. I think the mode parser should be a separate function | |
414 | that passes back something like (mask,set) description to the rest of | |
415 | the program. For bonus points there would be a test case for the | |
416 | parser. | |

424 | gnudiff, etc.) | |
425 | ||
426 | Just diff the temporary file with the destination file, and delete | |
427 | the tmp file rather than moving it into place. | |

437 | ||
438 | A bit hard to believe, but apparently it happens. | |

441 | Check "refuse options works" | |
442 | ||
443 | We need a test case for this... | |
444 | ||
445 | Was this broken when we changed to popt? | |

455 | PLATFORMS ------------------------------------------------------------ |
456 | ||
457 | Win32 | |
458 | ||
459 | Don't detach, because this messes up --srvany. | |
460 | ||
461 | http://sources.redhat.com/ml/cygwin/2001-08/msg00234.html | |
462 | ||
463 | According to "Effective TCP/IP Programming" (??) close() on a socket | |
464 | has incorrect behaviour on Windows -- it sends a RST packet to the | |
465 | other side, which gives a "connection reset by peer" error. On that | |
466 | platform we should probably do shutdown() instead. However, on Unix | |
467 | we are correct to call close(), because shutdown() discards | |
468 | untransmitted data. | |

470 | DEVELOPMENT ---------------------------------------------------------- |
471 | ||
472 | Splint | |
473 | ||
474 | Build rsync with SPLINT to try to find security holes. Add | |
475 | annotations as necessary. Keep track of the number of warnings | |
476 | found initially, and see how many of them are real bugs, or real | |
477 | security bugs. Knowing the percentage of likely hits would be | |
478 | really interesting for other projects. | |
479 | ||

480 | Torture test |
481 | ||
482 | Something that just keeps running rsync continuously over a data set | |
483 | likely to generate problems. | |
484 | ||
485 | Cross-testing | |
486 | ||
487 | Run current rsync versions against significant past releases. | |

495 | TESTING -------------------------------------------------------------- |
496 | ||
497 | Cross-test versions | |
498 | ||
499 | Part of the regression suite should be making sure that we don't | |
500 | break backwards compatibility: old clients vs new servers and so | |
501 | on. Ideally we would test the cross product of versions. | |
502 | ||
503 | It might be sufficient to test downloads from well-known public | |
504 | rsync servers running different versions of rsync. This will give | |
505 | some testing and also be the most common case for having different | |
506 | versions and not being able to upgrade. | |
507 | ||
508 | Test large files | |
509 | ||
510 | Sparse and non-sparse | |
511 | ||
512 | Mutator program | |
513 | ||
514 | Insert bytes, delete bytes, swap blocks, ... | |
515 | ||
516 | configure option to enable dangerous tests | |
517 | ||
518 | If tests are skipped, say why. | |

527 | them every time? | |

551 | ||
a2d2e5c0 MP |
552 | --no-detach and --no-fork options |
553 | ||
554 | Very useful for debugging. Also good when running under a | |
555 | daemon-monitoring process that tries to restart the service when the | |
556 | parent exits. | |
557 | ||
558 | hang/timeout friendliness | |

568 | internationalization |
569 | ||
570 | Change to using gettext(). Probably need to ship this for platforms | |
571 | that don't have it. | |
572 | ||
573 | Solicit translations. | |
574 | ||
3d90ec14 MP |
575 | Does anyone care? Before we bother modifying the code, we ought to |
576 | get the manual translated first, because that's possibly more useful | |
577 | and at any rate demonstrates desire. | |

580 | rsyncsh |
581 | ||
582 | Write a small emulation of interactive ftp as a Pythonn program | |
583 | that calls rsync. Commands such as "cd", "ls", "ls *.c" etc map | |
584 | fairly directly into rsync commands: it just needs to remember the | |
585 | current host, directory and so on. We can probably even do | |
586 | completion of remote filenames. |
