[Dovecot] looking for IMAP testing tool
by Phil Howard 19 May '10

19 May '10

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need to do the tests on a number of machines, under a number of user and domain names, and with a variety of parameters or destinations. This is for a suite of regression tests I am putting together intended to verify that configuration changes do not break things (or unbreak things that are supposed to not work). Anyone ever heard of such a tool? Open source would be preferred (better yet, my favorite programming languages: C, Pike, Python).

[Dovecot] problem compiling pigeonhole + my fix
by Andreas Schulze 19 May '10

19 May '10

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present. The following make failed with less helpfull errors. -> my fix is to call "autoreconf -i -f" again after autogen.sh should -f be added to autogen.sh ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

Re: [Dovecot] A new director service in v2.0 for NFS installations

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).

That file contribute to performance improvement, so I want to register myself with crontab. Please teach how to make dovecot.index and dovecot.index.cache manyually. Note. Dovecot LDA is not use. -- /*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/* Kenji Iuchi

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.
