sieve-dump(1) - Pigeonhole's Sieve script binary dump tool

SYNOPSIS

sieve-dump [options] sieve-binary [out-file]

DESCRIPTION

The sieve-dump command is part of Pigeonhole (pigeonhole(7)), which adds Sieve (RFC 5228) and ManageSieve (RFC 5804) support to Dovecot (dovecot(1)).

Using the sieve-dump command, Sieve binaries, which are produced for instance by sievec(1), can be transformed into a human-readable textual representation. This can provide valuable insight in how the Sieve script is executed. This is also particularly useful to view corrupt binaries that can result from bugs in the Sieve implementation. This tool is intended mainly for development purposes, so normally system administrators and users will not need to use this tool.

The format of the output is not explained here in detail, but it should be relatively easy to understand. The Sieve binaries comprise a set of data blocks, each of which can contain arbitrary data. For the base language implementation two blocks are used: the first containing a specification of all required language extensions and the second containing the main Sieve program. Compiled Sieve programs are represented as flat byte code and therefore the dump of the main program is a disassembly listing of the interpreter operations. Extensions can define new operations and use additional blocks. Therefore, the output of sieve-dump depends greatly on the language extensions used when compiling the binary.

OPTIONS

-c\ config-file

Alternative Dovecot configuration file path.

-D

Enable Sieve debugging.

-h

Produce per-block hexdump output of the whole binary instead of the normal human-readable output.

ARGUMENTS

sieve-binary

Specifies the Sieve binary file that needs to be dumped.

out-file

Specifies where the output must be written. This argument is optional. If omitted, the output is written to stdout.

EXIT STATUS

sieve-dump will exit with one of the following values:

0

Dump was successful. (EX_OK, EXIT_SUCCESS)

1

Operation failed. This is returned for almost all failures. (EXIT_FAILURE)

64

Invalid parameter given. (EX_USAGE)

FILES

/etc/dovecot/dovecot.conf

Dovecot's main configuration file.

/etc/dovecot/conf.d/90-sieve.conf

Sieve interpreter settings (included from Dovecot's main

configuration file)
