Fedora Project

  • Updated perl-MCE to 1.802 in Rawhide:

    • Default to Storable for serialization in Perl less than v5.12.0; Sereal 3.008+, if available, is loaded automatically in Perl v5.12+

  • Updated perl-Test-Simple to 1.302037 in Rawhide:

    • Restore PerlIO layer cloning on STDERR and STDOUT

Local Packages

  • Updated dovecot to 2.2.25:

    • lmtp: Start tracking lmtp_user_concurrency_limit and reject already at RCPT TO stage, which avoids MTA unnecessarily completing DATA only to get an error

    • doveadm: Previously, only mail settings were read from protocol doveadm { .. } section: now, all settings are

    • quota: Added quota_over_flag_lazy_check setting, which avoids checking quota_over_flag always at startup; instead, it's checked only when quota is being read for some other purpose

    • auth: Added a new auth policy service: http://wiki2.dovecot.org/Authentication/Policy

    • auth: Added PBKDF2 password scheme

    • auth: Added %{auth_user}, %{auth_username} and %{auth_domain}

    • auth: Added ":remove" suffix to extra field names to remove them

    • auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb extra field; the auth will wait until <timestamp> and optionally some randomness and then return success

    • dict proxy: Added idle_msecs=<n> parameter; support async operations

    • Performance improvements for handling large mailboxes
    • Added lib-dcrypt API for providing cryptographic functions

    • Added "doveadm mailbox update" command

    • IMAP commands' output now includes timing spent on the "syncing" stage if it's larger than 0
    • cassandra: Added metrics=<path> to connect setting to output internal statistics in JSON format every second to <path>

    • doveadm mailbox delete: Added -e parameter to delete only empty mailboxes; added --unsafe option to quickly delete a mailbox, bypassing lazy_expunge and quota plugins

    • doveadm user and auth cache flush are now available via doveadm-server

    • doveadm service stop <services> will stop specified services while leaving the rest of Dovecot running

    • Quota optimization: Avoid reading mail sizes for backends that don't need them (count, fs, dirsize)

    • Added mailbox { autoexpunge_max_mails=<n> } setting

    • Added welcome plugin: http://wiki2.dovecot.org/Plugins/Welcome

    • fts: Added fts_autoindex_exclude setting

    • v2.2.24's MIME parser was assert-crashing on mails having truncated MIME headers
    • auth: With multiple userdbs the final success/failure result wasn't always correct: the last userdb's result was always used

    • doveadm backup was sometimes deleting entire mailboxes unnecessarily

    • doveadm: Command -parameters weren't being sent to doveadm-server

    • If dovecot.index read failed e.g. because mmap() reached VSZ limit, an empty index could have been opened instead, corrupting the mailbox state

    • imapc: Fixed EXPUNGE handling when imapc_features didn't have modseq

    • lazy-expunge: Fixed a crash when copying failed, plus various other fixes

    • fts-lucene: Fixed crash on index rescan

    • auth_stats=yes produced broken output

    • dict-ldap: Various fixes

    • dict-sql: NULL values crashed; now they're treated as "not found"

  • I had to add a couple of fixes from upstream to get it to build on older distributions

  • Updated perl-MCE to 1.802 as per the Fedora version

  • Updated perl-Test2 to 1.302037 as per the Fedora perl-Test-Simple package

  • Updated perl-Test2-Suite to 0.000048:

    • ref-ref's can be used in deep comparisons
    • Fix mocking to override a base class's method
    • Fix global destruction warning
    • Minor test fix to keep 5.8 working
