3 /* |
1955 | 4 Here's a description of how we handle Maildir synchronization and |
5 it's problems: | |
6 | |
7 We want to be as efficient as we can. The most efficient way to | |
3520 | 8 check if changes have occurred is to stat() the new/ and cur/ |
1955 | 9 directories and uidlist file - if their mtimes haven't changed, |
10 there's no changes and we don't need to do anything. | |
11 | |
12 Problem 1: Multiple changes can happen within a single second - | |
13 nothing guarantees that once we synced it, someone else didn't just | |
14 then make a modification. Such modifications wouldn't get noticed | |
3520 | 15 until a new modification occurred later. |
1955 | 16 |
17 Problem 2: Syncing cur/ directory is much more costly than syncing | |
18 new/. Moving mails from new/ to cur/ will always change mtime of | |
19 cur/ causing us to sync it as well. | |
20 | |
21 Problem 3: We may not be able to move mail from new/ to cur/ | |
22 because we're out of quota, or simply because we're accessing a | |
23 read-only mailbox. | |
24 | |
25 | |
26 MAILDIR_SYNC_SECS | |
27 ----------------- | |
28 | |
29 Several checks below use MAILDIR_SYNC_SECS, which should be maximum | |
30 clock drift between all computers accessing the maildir (eg. via | |
31 NFS), rounded up to next second. Our default is 1 second, since | |
32 everyone should be using NTP. | |
33 | |
34 Note that setting it to 0 works only if there's only one computer | |
35 accessing the maildir. It's practically impossible to make two | |
36 clocks _exactly_ synchronized. | |
37 | |
38 It might be possible to only use file server's clock by looking at | |
39 the atime field, but I don't know how well that would actually work. | |
40 | |
41 cur directory | |
42 ------------- | |
43 | |
44 We have dirty_cur_time variable which is set to cur/ directory's | |
45 mtime when it's >= time() - MAILDIR_SYNC_SECS and we _think_ we have | |
46 synchronized the directory. | |
47 | |
48 When dirty_cur_time is non-zero, we don't synchronize the cur/ | |
49 directory until | |
50 | |
51 a) cur/'s mtime changes | |
52 b) opening a mail fails with ENOENT | |
53 c) time() > dirty_cur_time + MAILDIR_SYNC_SECS | |
54 | |
55 This allows us to modify the maildir multiple times without having | |
56 to sync it at every change. The sync will eventually be done to | |
57 make sure we didn't miss any external changes. | |
58 | |
59 The dirty_cur_time is set when: | |
60 | |
61 - we change message flags | |
62 - we expunge messages | |
63 - we move mail from new/ to cur/ | |
64 - we sync cur/ directory and it's mtime is >= time() - MAILDIR_SYNC_SECS | |
65 | |
66 It's unset when we do the final syncing, ie. when mtime is | |
67 older than time() - MAILDIR_SYNC_SECS. | |
68 | |
69 new directory | |
70 ------------- | |
71 | |
72 If new/'s mtime is >= time() - MAILDIR_SYNC_SECS, always synchronize | |
73 it. dirty_cur_time-like feature might save us a few syncs, but | |
74 that might break a client which saves a mail in one connection and | |
75 tries to fetch it in another one. new/ directory is almost always | |
76 empty, so syncing it should be very fast anyway. Actually this can | |
77 still happen if we sync only new/ dir while another client is also | |
78 moving mails from it to cur/ - it takes us a while to see them. | |
79 That's pretty unlikely to happen however, and only way to fix it | |
80 would be to always synchronize cur/ after new/. | |
81 | |
82 Normally we move all mails from new/ to cur/ whenever we sync it. If | |
83 it's not possible for some reason, we mark the mail with "probably | |
84 exists in new/ directory" flag. | |
85 | |
86 If rename() still fails because of ENOSPC or EDQUOT, we still save | |
87 the flag changes in index with dirty-flag on. When moving the mail | |
88 to cur/ directory, or when we notice it's already moved there, we | |
89 apply the flag changes to the filename, rename it and remove the | |
90 dirty flag. If there's dirty flags, this should be tried every time | |
91 after expunge or when closing the mailbox. | |
92 | |
93 uidlist | |
94 ------- | |
95 | |
96 This file contains UID <-> filename mappings. It's updated only when | |
97 new mail arrives, so it may contain filenames that have already been | |
98 deleted. Updating is done by getting uidlist.lock file, writing the | |
99 whole uidlist into it and rename()ing it over the old uidlist. This | |
100 means there's no need to lock the file for reading. | |
101 | |
102 Whenever uidlist is rewritten, it's mtime must be larger than the old | |
103 one's. Use utime() before rename() if needed. Note that inode checking | |
104 wouldn't have been sufficient as inode numbers can be reused. | |
105 | |
106 This file is usually read the first time you need to know filename for | |
107 given UID. After that it's not re-read unless new mails come that we | |
108 don't know about. | |
109 | |
110 broken clients | |
111 -------------- | |
112 | |
113 Originally the middle identifier in Maildir filename was specified | |
114 only as <process id>_<delivery counter>. That however created a | |
115 problem with randomized PIDs which made it possible that the same | |
116 PID was reused within one second. | |
117 | |
118 So if within one second a mail was delivered, MUA moved it to cur/ | |
119 and another mail was delivered by a new process using same PID as | |
120 the first one, we likely ended up overwriting the first mail when | |
121 the second mail was moved over it. | |
122 | |
123 Nowadays everyone should be giving a bit more specific identifier, | |
124 for example include microseconds in it which Dovecot does. | |
125 | |
126 There's a simple way to prevent this from happening in some cases: | |
127 Don't move the mail from new/ to cur/ if it's mtime is >= time() - | |
128 MAILDIR_SYNC_SECS. The second delivery's link() call then fails | |
129 because the file is already in new/, and it will then use a | |
130 different filename. There's a few problems with this however: | |
131 | |
132 - it requires extra stat() call which is unneeded extra I/O | |
133 - another MUA might still move the mail to cur/ | |
134 - if first file's flags are modified by either Dovecot or another | |
135 MUA, it's moved to cur/ (you _could_ just do the dirty-flagging | |
136 but that'd be ugly) | |
137 | |
138 Because this is useful only for very few people and it requires | |
139 extra I/O, I decided not to implement this. It should be however | |
140 quite easy to do since we need to be able to deal with files in new/ | |
141 in any case. | |
142 | |
143 It's also possible to never accidentally overwrite a mail by using | |
144 link() + unlink() rather than rename(). This however isn't very | |
145 good idea as it introduces potential race conditions when multiple | |
146 clients are accessing the mailbox: | |
147 | |
148 Trying to move the same mail from new/ to cur/ at the same time: | |
149 | |
150 a) Client 1 uses slightly different filename than client 2, | |
151 for example one sets read-flag on but the other doesn't. | |
152 You have the same mail duplicated now. | |
153 | |
154 b) Client 3 sees the mail between Client 1's and 2's link() calls | |
155 and changes it's flag. You have the same mail duplicated now. | |
156 | |
157 And it gets worse when they're unlink()ing in cur/ directory: | |
158 | |
159 c) Client 1 changes mails's flag and client 2 changes it back | |
160 between 1's link() and unlink(). The mail is now expunged. | |
161 | |
162 d) If you try to deal with the duplicates by unlink()ing another | |
163 one of them, you might end up unlinking both of them. | |
164 | |
165 So, what should we do then if we notice a duplicate? First of all, | |
166 it might not be a duplicate at all, readdir() might have just | |
167 returned it twice because it was just renamed. What we should do is | |
168 create a completely new base name for it and rename() it to that. | |
169 If the call fails with ENOENT, it only means that it wasn't a | |
170 duplicate after all. | |
