|
|
|
|
The \module{msilib} supports the creation of Microsoft Installer
|
|
(\code{.msi}) files. Because these files often contain an embedded
|
|
``cabinet'' file (\code{.cab}), it also exposes an API to create
|
|
CAB files. Support for reading \code{.cab} files is currently not
|
|
implemented; read support for the \code{.msi} database is possible.
|
|
|
|
This package aims to provide complete access to all tables in an
|
|
\code{.msi} file, therefore, it is a fairly low-level API. Two
|
|
primary applications of this package are the \module{distutils}
|
|
command \code{bdist_msi}, and the creation of Python installer
|
|
package itself (although that currently uses a different version
|
|
of \code{msilib}).
|
|
|
|
The package contents can be roughly split into four parts:
|
|
low-level CAB routines, low-level MSI routines, higher-level
|
|
MSI routines, and standard table structures.
|
|
|
|
\begin{funcdesc}{FCICreate}{cabname, files}
|
|
Create a new CAB file named \var{cabname}. \var{files} must
|
|
be a list of tuples, each containing the name of the file on
|
|
disk, and the name of the file inside the CAB file.
|
|
|
|
The files are added to the CAB file in the order they appear
|
|
in the list. All files are added into a single CAB file,
|
|
using the MSZIP compression algorithm.
|
|
|
|
Callbacks to Python for the various steps of MSI creation
|
|
are currently not exposed.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{UUIDCreate}{}
|
|
Return the string representation of a new unique identifier.
|
|
This wraps the Windows API functions \cfunction{UuidCreate} and
|
|
\cfunction{UuidToString}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{OpenDatabase}{path, persist}
|
|
Return a new database object by calling MsiOpenDatabase.
|
|
\var{path} is the file name of the
|
|
MSI file; \var{persist} can be one of the constants
|
|
\code{MSIDBOPEN_CREATEDIRECT}, \code{MSIDBOPEN_CREATE},
|
|
\code{MSIDBOPEN_DIRECT}, \code{MSIDBOPEN_READONLY}, or
|
|
\code{MSIDBOPEN_TRANSACT}, and may include the flag
|
|
\code{MSIDBOPEN_PATCHFILE}. See the Microsoft documentation for
|
|
the meaning of these flags; depending on the flags,
|
|
an existing database is opened, or a new one created.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{CreateRecord}{count}
|
|
Return a new record object by calling \cfunction{MSICreateRecord}.
|
|
\var{count} is the number of fields of the record.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{init_database}{name, schema, ProductName, ProductCode, ProductVersion, Manufacturer}
|
|
Create and return a new database \var{name}, initialize it
|
|
with \var{schema}, and set the properties \var{ProductName},
|
|
\var{ProductCode}, \var{ProductVersion}, and \var{Manufacturer}.
|
|
|
|
\var{schema} must be a module object containing \code{tables} and
|
|
\code{_Validation_records} attributes; typically,
|
|
\module{msilib.schema} should be used.
|
|
|
|
The database will contain just the schema and the validation
|
|
records when this function returns.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{add_data}{database, records}
|
|
Add all \var{records} to \var{database}. \var{records} should
|
|
be a list of tuples, each one containing all fields of a record
|
|
according to the schema of the table. For optional fields,
|
|
\code{None} can be passed.
|
|
|
|
Field values can be int or long numbers, strings, or instances
|
|
of the Binary class.
|
|
\end{funcdesc}
|
|
|
|
\begin{classdesc}{Binary}{filename}
|
|
Represents entries in the Binary table; inserting such
|
|
an object using \function{add_data} reads the file named
|
|
\var{filename} into the table.
|
|
\end{classdesc}
|
|
|
|
\begin{funcdesc}{add_tables}{database, module}
|
|
Add all table content from \var{module} to \var{database}.
|
|
\var{module} must contain an attribute \var{tables}
|
|
listing all tables for which content should be added,
|
|
and one attribute per table that has the actual content.
|
|
|
|
This is typically used to install the sequence tables.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{add_stream}{database, name, path}
|
|
Add the file \var{path} into the \code{_Stream} table
|
|
of \var{database}, with the stream name \var{name}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{gen_uuid}{}
|
|
Return a new UUID, in the format that MSI typically
|
|
requires (i.e. in curly braces, and with all hexdigits
|
|
in upper-case).
|
|
\end{funcdesc}

\end{methoddesc}
|
|
|
|
\subsection{Directory Objects\label{msi-directory}}
|
|
|
|
\begin{classdesc}{Directory}{database, cab, basedir, physical,
|
|
logical, default, component, \optional{componentflags}}
|
|
Create a new directory in the Directory table. There is a current
|
|
component at each point in time for the directory, which is either
|
|
explicitly created through \method{start_component}, or implicitly when files
|
|
are added for the first time. Files are added into the current
|
|
component, and into the cab file. To create a directory, a base
|
|
directory object needs to be specified (can be \code{None}), the path to
|
|
the physical directory, and a logical directory name. \var{default}
|
|
specifies the DefaultDir slot in the directory table. \var{componentflags}
|
|
specifies the default flags that new components get.
|
|
\end{classdesc}
|

\begin{methoddesc}[Directory]{start_component}{\optional{component\optional{,
|
|
feature\optional{, flags\optional{, keyfile\optional{, uuid}}}}}}
|
|
Add an entry to the Component table, and make this component the
|
|
current component for this directory. If no component name is given, the
|
|
directory name is used. If no \var{feature} is given, the current feature
|
|
is used. If no \var{flags} are given, the directory's default flags are
|
|
used. If no \var{keyfile} is given, the KeyPath is left null in the
|
|
Component table.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}[Directory]{add_file}{file\optional{, src\optional{,
|
|
version\optional{, language}}}}
|
|
Add a file to the current component of the directory, starting a new
|
|
one if there is no current component. By default, the file name
|
|
in the source and the file table will be identical. If the \var{src} file
|
|
is specified, it is interpreted relative to the current
|
|
directory. Optionally, a \var{version} and a \var{language} can be specified for
|
|
the entry in the File table.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}[Directory]{glob}{pattern\optional{, exclude}}
|
|
Add a list of files to the current component as specified in the glob
|
|
pattern. Individual files can be excluded in the \var{exclude} list.
|
|
\end{methoddesc}
|
|
|
|
\begin{methoddesc}[Directory]{remove_pyc}{}

\subsection{Precomputed tables\label{msi-tables}}
|
|
|
|
\module{msilib} provides a few subpackages that contain
|
|
only schema and table definitions. Currently, these definitions
|
|
are based on MSI version 2.0.
|
|
|
|
\begin{datadesc}{schema}
|
|
This is the standard MSI schema for MSI 2.0, with the
|
|
\var{tables} variable providing a list of table definitions,
|
|
and \var{_Validation_records} providing the data for
|
|
MSI validation.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{sequence}
|
|
This module contains table contents for the standard sequence
|
|
tables: \var{AdminExecuteSequence}, \var{AdminUISequence},
|
|
\var{AdvtExecuteSequence}, \var{InstallExecuteSequence}, and
|
|
\var{InstallUISequence}.
|
|
\end{datadesc}
|
|
|
|
\begin{datadesc}{text}
|
|
This module contains definitions for the UIText and ActionText
|
|
tables, for the standard installer actions.
|
|
\end{datadesc}
