| 6 | IMPORTANT ------------------------------------------------------------ |

| 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. |
| 18 | |
| 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?) |

| 28 | |
| 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 |
| 43 | |
| 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 |
| 49 | addresses.) This is kind of implemented already. |
| 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 | |
| 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. |
| 74 | |
| 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. |
| 83 | |
| 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. |
| 115 | |
| 116 | BUILD FARM ----------------------------------------------------------- |
| 117 | |
| 118 | Add machines |
| 119 | |
| 120 | AMDAHL UTS (Dave Dykstra) |
| 121 | |
| 122 | Cygwin (on different versions of Win32?) |
| 123 | |
| 124 | HP-UX variants (via HP?) |
| 125 | |
| 126 | SCO |
| 127 | |
| 128 | NICE ----------------------------------------------------------------- |
| 129 | |
| 130 | SIGHUP |
| 131 | |
| 132 | Re-read config file (just exec() ourselves) rather than exiting. |
| 133 | |
| 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? |
| 152 | |
| 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. |
