sieve-dump - Pigeonhole's Sieve script binary dump tool
sieve-dump [options] sieve-binary [out-file]
The sieve-dump command is part of the Pigeonhole Project
(pigeonhole(7)), which adds Sieve (RFC 5228) support to the Dovecot
secure IMAP and POP3 server (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.
Alternative Dovecot configuration file path.
-h Produce per-block hexdump output of the whole binary instead of
the normal human-readable output.
Set the available extensions. The parameter is a space-separated
list of the active extensions. By prepending the extension
identifiers with + or -, extensions can be included or excluded
relative to the default set of extensions. If no extensions have
a + or - prefix, only those extensions that are explicitly
listed will be enabled. Unknown extensions are ignored and a
warning is produced. By default, all supported extensions are
available, except for deprecated extensions or those that are
still under development.
For example -x "+imapflags -enotify" will enable the deprecated
imapflags extension along with all extensions that are available
by default, except for the enotify extension.
Specifies the Sieve binary file that needs to be dumped.
Specifies where the output must be written. This argument is
optional. If omitted, the output is written to stdout.
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.
64 Invalid parameter given. (EX_USAGE)
