Also, introduce new option 'logger-prefix' to determine the prefix of
each log line.

Previously getpwuid() was called to determine the user's home directory,
while the XDG specification explicitely mentions $HOME.
Conveniently our docs always mentioned ~/, which on POSIX-compliant
systems expands to the value of the variable HOME (and the result is
unspecified when the variable is unset). Cf. Shell and Utilities volume
of POSIX.1-2017, sec. 2.6.1:

That is, without leading reference, and where the hierarchy delimiter is
replaced with null characters.
/!\ This changes breaks backward compatibility!

It is passed to `/bin/sh -c` when it contains shell metacharacters; and
split into words and passed to execvp(3) otherwise.

(Since c8fb54897f046a5a3fb4c1d45dc21fd8bcd882e3 the value no longer
needs to stard with a forward slash.)

This is useful for synchronizing multiple remote servers against
different namespaces belonging to the same local IMAP server (using a
different InterIMAP instance for each local namespace ↔ remote
synchronization, for instance with the newy provided systemd template
unit file).

Rather than two pipe(2). Also, use SOCK_CLOEXEC to save a fcntl() call
when setting the close-on-exec flag on the socket (even though Perl will
likely call fcntl() anyway).

SQLite processes every INTEGER values as a 8-byte signed integer, so we
need to manually do the conversion from/to uint64_t client-side if we
don't want to overflow or receive floats.
https://www.sqlite.org/datatype3.html#storage_classes_and_datatypes
http://jakegoulding.com/blog/2011/02/06/sqlite-64-bit-integers/
We could also do the same trick for local/remote UIDs, UIDVALITY and
UIDNEXT values to slim the database down at the expense of pre/post-
processing. (Values of SQLite's INTEGER class are 1, 2, 3, 4, 6, or 8
bytes signed integers depending on the manitudes, so we could save some
space for values ≥2³¹.) But that seems a little overkill.

Setting the 'foreign_keys' PRAGMA during a multi-statement transaction
(when SQLite is not in autocommit mode) is a no-op.

Following recommendation from
https://www.imapwiki.org/ClientImplementation/MailboxList#Hierarchy_separators
Instead, use null characters internally, and substitute them with the
local and remote hierarchy delimiters (which thus no longer need to
match) for IMAP commands. This require a database schema upgrade to
alter the mailbox name column type from TEXT to BLOB. We're using
SQLite's user_version PRAGMA to keep track of schema version; beware
that `.dump` doesn't export its value!
In logging messages, local and remote mailbox names are shown as is
(with their respective delimiters) while database mailbox names are
shown by replacing null characters with the *local* hierarchy delimiter.
Moreover for mailbox names specified on the command line or the
configuration file (with the "list-mailbox" option) the *local*
hierarchy delimiter should be used.
|
|
|
|
| |
Also, accept comma-separated values for --target.
|
|
|
|
|
|
| |
This never happens for a single LIST command, but may happen if
mailboxes from different namespaces are being listed. The workaround
here is to run a new interimap instance for each namespace.
|
|
|
|
|
| |
This is useful for defining names containing control characters (incl.
\0 for unspecified hierarchy delimiter).
|
|
|
|
| |
Also, write which --target to use in --delete command suggestions.

Not 1*ATOM-CHAR / string. Also accept LIST responses mailbox names
containing '%', '*', or ']'.
From RFC 3501:
astring = 1*ASTRING-CHAR / string
ASTRING-CHAR = ATOM-CHAR / resp-specials
list = "LIST" SP mailbox SP list-mailbox
list-mailbox = 1*list-char / string
list-char = ATOM-CHAR / list-wildcards / resp-specials
list-wildcards = "%" / "*"
resp-specials = "]"

Compression asside, this saves 3 bytes and one round-trip on servers not
supporting non-synchronizing literals, and 4 bytes otherwise.

The were returned as escaped quoted specials, like "\\", not as a single
character (backslash in this case).

Also, change "SSL_protocols" default value from "!SSLv2 !SSLv3" to
"!SSLv2 !SSLv3 !TLSv1 !TLSv1.1". I.e., only enable TLSv1.2 and later,
which is the default in Debian's OpenSSL as of 1.1.1-2, cf.
https://tracker.debian.org/news/998835/accepted-openssl-111-2-source-into-unstable/ .

This is most likely useless in our case since the TCP keepalive time is
usually much higher than the IMAP timeout.

“If the server does not know how to decode the section's CTE, it MUST
fail the request and issue a "NO" response that contains the
"UNKNOWN-CTE" extended response code.” — [RFC3516 section 4.3]
Unfortunately the client doesn't know which message couldn't be decoded,
so it can't fallback and use BODY instead.
This made ‘use-binary=NO’ pretty much mandatory. Hence we remove
support for BINARY [RFC3516]. Instead, we increase the thresold for
when to add Zlib full flush points from 4096 to the buffer size (32768).
