8 | Cross-test versions | |
9 | ||
10 | Part of the regression suite should be making sure that we don't | |
11 | break backwards compatibility: old clients vs new servers and so | |
12 | on. Ideally we would test the cross product of versions. | |
13 | ||
14 | It might be sufficient to test downloads from well-known public | |
15 | rsync servers running different versions of rsync. This will give | |
16 | some testing and also be the most common case for having different | |
17 | versions and not being able to upgrade. | |

19 | use chroot |
20 | ||
21 | If the platform doesn't support it, then don't even try. | |
22 | ||
23 | If running as non-root, then don't fail, just give a warning. | |
24 | (There was a thread about this a while ago?) | |

29 | --files-from | |
30 | ||
31 | Avoids traversal. Better option than a pile of --include statements | |
32 | for people who want to generate the file list using a find(1) | |
33 | command or a script. | |
34 | ||
35 | Performance | |
36 | ||
37 | Traverse just one directory at a time. Tridge says it's possible. | |
38 | ||
39 | Can possibly also be smarter about memory use while looking for hard | |
40 | links by reducing the refcount as we find alternative names. | |
41 | ||
42 | IPv6 | |

44 | Implement suggestions from http://www.kame.net/newsletter/19980604/ |
45 | and ftp://ftp.iij.ad.jp/pub/RFC/rfc2553.txt | |
46 | ||
47 | If a host has multiple addresses, then listen try to connect to all | |
48 | in order until we get through. (getaddrinfo may return multiple | |
c10b0bdd | 49 | addresses.) This is kind of implemented already. |
c33e3e39 MP |
50 | |
51 | Possibly also when starting as a server we may need to listen on | |
52 | multiple passive addresses. This might be a bit harder, because we | |
53 | may need to select on all of them. Hm. | |
54 | ||
a2d2e5c0 MP |
55 | Define a syntax for IPv6 literal addresses. Since they include |
56 | colons, they tend to break most naming systems, including ours. | |
57 | Based on the HTTP IPv6 syntax, I think we should use | |
58 | ||
59 | rsync://[::1]/foo/bar | |
60 | [::1]::bar | |
61 | ||
62 | which should just take a small change to the parser code. | |
63 | ||

64 | Errors |
65 | ||
66 | If we hang or get SIGINT, then explain where we were up to. Perhaps | |
67 | have a static buffer that contains the current function name, or | |
68 | some kind of description of what we were trying to do. This is a | |
69 | little easier on people than needing to run strace/truss. | |
70 | ||
71 | "The dungeon collapses! You are killed." Rather than "unexpected | |
72 | eof" give a message that is more detailed if possible and also more | |
73 | helpful. | |

75 | File attributes |
76 | ||
77 | Device major/minor numbers should be at least 32 bits each. See | |
78 | http://lists.samba.org/pipermail/rsync/2001-November/005357.html | |
79 | ||
80 | Transfer ACLs. Need to think of a standard representation. | |
81 | Probably better not to even try to convert between NT and POSIX. | |
82 | Possibly can share some code with Samba. | |

84 | Empty directories |
85 | ||
86 | With the current common --include '*/' --exclude '*' pattern, people | |
87 | can end up with many empty directories. We might avoid this by | |
88 | lazily creating such directories. | |
89 | ||
90 | zlib | |
91 | ||
92 | Perhaps don't use our own zlib. Will we actually be incompatible, | |
93 | or just be slightly less efficient? | |
94 | ||
95 | logging | |
96 | ||
97 | Perhaps flush stdout after each filename, so that people trying to | |
98 | monitor progress in a log file can do so more easily. See | |
99 | http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=48108 | |

101 | PLATFORMS ------------------------------------------------------------ |
102 | ||
103 | Win32 | |
104 | ||
105 | Don't detach, because this messes up --srvany. | |
106 | ||
107 | http://sources.redhat.com/ml/cygwin/2001-08/msg00234.html | |
108 | ||
109 | According to "Effective TCP/IP Programming" (??) close() on a socket | |
110 | has incorrect behaviour on Windows -- it sends a RST packet to the | |
111 | other side, which gives a "connection reset by peer" error. On that | |
112 | platform we should probably do shutdown() instead. However, on Unix | |
113 | we are correct to call close(), because shutdown() discards | |
114 | untransmitted data. | |

130 | SIGHUP |
131 | ||
132 | Re-read config file (just exec() ourselves) rather than exiting. | |
133 | ||
a2d2e5c0 MP |
134 | --no-detach and --no-fork options |
135 | ||
136 | Very useful for debugging. Also good when running under a | |
137 | daemon-monitoring process that tries to restart the service when the | |
138 | parent exits. | |
139 | ||
140 | hang/timeout friendliness | |
141 | ||
142 | On | |
143 | ||
144 | internationalization | |
145 | ||
146 | Change to using gettext(). Probably need to ship this for platforms | |
147 | that don't have it. | |
148 | ||
149 | Solicit translations. | |
150 | ||
151 | Does anyone care? | |

153 | rsyncsh |
154 | ||
155 | Write a small emulation of interactive ftp as a Pythonn program | |
156 | that calls rsync. Commands such as "cd", "ls", "ls *.c" etc map | |
157 | fairly directly into rsync commands: it just needs to remember the | |
158 | current host, directory and so on. We can probably even do | |
159 | completion of remote filenames. | |
