\section{\module{msilib} ---         Read and write Microsoft Installer files} \declaremodule{standard}{msilib}  \platform{Windows}\modulesynopsis{Creation of Microsoft Installer files, and CAB files.}\moduleauthor{Martin v. L\"owis}{martin@v.loewis.de}\sectionauthor{Martin v. L\"owis}{martin@v.loewis.de} \index{msi} \versionadded{2.5} 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 createCAB files. Support for reading \code{.cab} files is currently notimplemented; 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. Twoprimary applications of this package are the \module{distutils}command \code{bdist_msi}, and the creation of Python installerpackage itself (although that currently uses a different versionof \code{msilib}). The package contents can be roughly split into four parts:low-level CAB routines, low-level MSI routines, higher-levelMSI 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} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devnotes/winprog/fcicreate.asp]{FCICreateFile}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rpc/rpc/uuidcreate.asp]{UuidCreate}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rpc/rpc/uuidtostring.asp]{UuidToString}{}\end{seealso} \subsection{Database Objects\label{database-objects}} \begin{methoddesc}{OpenView}{sql}  Return a view object, by calling \cfunction{MSIDatabaseOpenView}.  \var{sql} is the SQL statement to execute.\end{methoddesc} \begin{methoddesc}{Commit}{}  Commit the changes pending in the current transaction,  by calling \cfunction{MSIDatabaseCommit}.\end{methoddesc} \begin{methoddesc}{GetSummaryInformation}{count}  Return a new summary information object, by calling  \cfunction{MsiGetSummaryInformation}.  \var{count} is the maximum number of  updated values.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiopenview.asp]{MSIOpenView}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msidatabasecommit.asp]{MSIDatabaseCommit}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msigetsummaryinformation.asp]{MSIGetSummaryInformation}{}\end{seealso} \subsection{View Objects\label{view-objects}} \begin{methoddesc}{Execute}{\optional{params=None}}  Execute the SQL query of the view, through \cfunction{MSIViewExecute}.  \var{params} is an optional record describing actual values  of the parameter tokens in the query.\end{methoddesc} \begin{methoddesc}{GetColumnInfo}{kind}  Return a record describing the columns of the view, through  calling \cfunction{MsiViewGetColumnInfo}. \var{kind} can be either  \code{MSICOLINFO_NAMES} or \code{MSICOLINFO_TYPES}.\end{methoddesc} \begin{methoddesc}{Fetch}{}  Return a result record of the query, through calling  \cfunction{MsiViewFetch}.\end{methoddesc} \begin{methoddesc}{Modify}{kind, data}  Modify the view, by calling \cfunction{MsiViewModify}. \var{kind}  can be one of  \code{MSIMODIFY_SEEK}, \code{MSIMODIFY_REFRESH},  \code{MSIMODIFY_INSERT}, \code{MSIMODIFY_UPDATE}, \code{MSIMODIFY_ASSIGN},  \code{MSIMODIFY_REPLACE}, \code{MSIMODIFY_MERGE}, \code{MSIMODIFY_DELETE},  \code{MSIMODIFY_INSERT_TEMPORARY}, \code{MSIMODIFY_VALIDATE},  \code{MSIMODIFY_VALIDATE_NEW}, \code{MSIMODIFY_VALIDATE_FIELD}, or  \code{MSIMODIFY_VALIDATE_DELETE}.   \var{data} must be a record describing the new data.\end{methoddesc} \begin{methoddesc}{Close}{}  Close the view, through \cfunction{MsiViewClose}.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiviewexecute.asp]{MsiViewExecute}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiviewgetcolumninfo.asp]{MSIViewGetColumnInfo}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiviewfetch.asp]{MsiViewFetch}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiviewmodify.asp]{MsiViewModify}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msiviewclose.asp]{MsiViewClose}{}\end{seealso} \subsection{Summary Information Objects\label{summary-objects}} \begin{methoddesc}{GetProperty}{field}  Return a property of the summary, through \cfunction{MsiSummaryInfoGetProperty}.  \var{field} is the name of the property, and can be one of the  constants  \code{PID_CODEPAGE}, \code{PID_TITLE}, \code{PID_SUBJECT},  \code{PID_AUTHOR}, \code{PID_KEYWORDS}, \code{PID_COMMENTS},  \code{PID_TEMPLATE}, \code{PID_LASTAUTHOR}, \code{PID_REVNUMBER},  \code{PID_LASTPRINTED}, \code{PID_CREATE_DTM}, \code{PID_LASTSAVE_DTM},  \code{PID_PAGECOUNT}, \code{PID_WORDCOUNT}, \code{PID_CHARCOUNT},  \code{PID_APPNAME}, or \code{PID_SECURITY}.\end{methoddesc} \begin{methoddesc}{GetPropertyCount}{}  Return the number of summary properties, through  \cfunction{MsiSummaryInfoGetPropertyCount}.\end{methoddesc} \begin{methoddesc}{SetProperty}{field, value}  Set a property through \cfunction{MsiSummaryInfoSetProperty}. \var{field}  can have the same values as in \method{GetProperty}, \var{value}  is the new value of the property. Possible value types are integer  and string.\end{methoddesc} \begin{methoddesc}{Persist}{}  Write the modified properties to the summary information stream,  using \cfunction{MsiSummaryInfoPersist}.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msisummaryinfogetproperty.asp]{MsiSummaryInfoGetProperty}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msisummaryinfogetpropertycount.asp]{MsiSummaryInfoGetPropertyCount}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msisummaryinfosetproperty.asp]{MsiSummaryInfoSetProperty}{}  \seetitle[http://msdn.microsoft.com/library/default.asp?url=/library/en-us/msi/setup/msisummaryinfopersist.asp]{MsiSummaryInfoPersist}{}\end{seealso} \subsection{Record Objects\label{record-objects}} \begin{methoddesc}{GetFieldCount}{}  Return the number of fields of the record, through \cfunction{MsiRecordGetFieldCount}.\end{methoddesc} \begin{methoddesc}{SetString}{field, value}  Set \var{field} to \var{value} through \cfunction{MsiRecordSetString}.  \var{field} must be an integer; \var{value} a string.\end{methoddesc} \begin{methoddesc}{SetStream}{field, value}  Set \var{field} to the contents of the file named \var{value},  through \cfunction{MsiRecordSetStream}.  \var{field} must be an integer; \var{value} a string.\end{methoddesc} \begin{methoddesc}{SetInteger}{field, value}  Set \var{field} to \var{value} through \cfunction{MsiRecordSetInteger}.

During MSI construction,  files will be added simultaneously to the \code{Files} table, and  to a CAB file. Then, when all files have been added, the CAB file  can be written, then added to the MSI file.   \var{name} is the name of the CAB file in the MSI file.\end{classdesc} \begin{methoddesc}[CAB]{append}{full, logical}  Add the file with the pathname \var{full} to the CAB file,  under the name \var{logical}. If there is already a file  named \var{logical}, a new file name is created.   Return the index of the file in the CAB file, and the  new name of the file inside the CAB file.\end{methoddesc} \begin{methoddesc}[CAB]{append}{database}  Generate a CAB file, add it as a stream to the MSI file,  put it into the \code{Media} table, and remove the generated  file from the disk.\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}{}  Remove \code{.pyc}/\code{.pyo} files on uninstall.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/directory_table.asp]{Directory Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/file_table.asp]{File Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/component_table.asp]{Component Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/featurecomponents_table.asp]{FeatureComponents Table}{}\end{seealso}  \subsection{Features\label{features}} \begin{classdesc}{Feature}{database, id, title, desc, display\optional{,    level=1\optional{, parent\optional{, directory\optional{,     attributes=0}}}}}   Add a new record to the \code{Feature} table, using the values  \var{id}, \var{parent.id}, \var{title}, \var{desc}, \var{display},  \var{level}, \var{directory}, and \var{attributes}. The resulting  feature object can be passed to the \method{start_component} method  of \class{Directory}.\end{classdesc} \begin{methoddesc}[Feature]{set_current}{}  Make this feature the current feature of \module{msilib}.  New components are automatically added to the default feature,  unless a feature is explicitly specified.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/feature_table.asp]{Feature Table}{}\end{seealso} \subsection{GUI classes\label{msi-gui}} \module{msilib} provides several classes that wrap the GUI tables inan MSI database. However, no standard user interface is provided; use\module{bdist_msi} to create MSI files with a user-interface forinstalling Python packages. \begin{classdesc}{Control}{dlg, name}  Base class of the dialog controls. \var{dlg} is the dialog object  the control belongs to, and \var{name} is the control's name.\end{classdesc} \begin{methoddesc}[Control]{event}{event, argument\optional{,    condition = ``1''\optional{, ordering}}}   Make an entry into the \code{ControlEvent} table for this control.\end{methoddesc} \begin{methoddesc}[Control]{mapping}{event, attribute}  Make an entry into the \code{EventMapping} table for this control.\end{methoddesc} \begin{methoddesc}[Control]{condition}{action, condition}  Make an entry into the \code{ControlCondition} table for this control.\end{methoddesc}  \begin{classdesc}{RadioButtonGroup}{dlg, name, property}  Create a radio button control named \var{name}. \var{property}  is the installer property that gets set when a radio button  is selected.\end{classdesc} \begin{methoddesc}[RadioButtonGroup]{add}{name, x, y, width, height, text                                          \optional{, value}}  Add a radio button named \var{name} to the group, at the  coordinates \var{x}, \var{y}, \var{width}, \var{height}, and  with the label \var{text}. If \var{value} is omitted, it  defaults to \var{name}.\end{methoddesc}           \begin{classdesc}{Dialog}{db, name, x, y, w, h, attr, title, first,     default, cancel}  Return a new \class{Dialog} object. An entry in the \code{Dialog} table  is made, with the specified coordinates, dialog attributes, title,  name of the first, default, and cancel controls.\end{classdesc} \begin{methoddesc}[Dialog]{control}{name, type, x, y, width, height,                   attributes, property, text, control_next, help}  Return a new \class{Control} object. An entry in the \code{Control} table  is made with the specified parameters.   This is a generic method; for specific types, specialized methods  are provided.\end{methoddesc}  \begin{methoddesc}[Dialog]{text}{name, x, y, width, height, attributes, text}  Add and return a \code{Text} control.\end{methoddesc} \begin{methoddesc}[Dialog]{bitmap}{name, x, y, width, height, text}  Add and return a \code{Bitmap} control.\end{methoddesc} \begin{methoddesc}[Dialog]{line}{name, x, y, width, height}  Add and return a \code{Line} control.\end{methoddesc} \begin{methoddesc}[Dialog]{pushbutton}{name, x, y, width, height, attributes,                                  text, next_control}  Add and return a \code{PushButton} control.\end{methoddesc} \begin{methoddesc}[Dialog]{radiogroup}{name, x, y, width, height,                                  attributes, property, text, next_control}  Add and return a \code{RadioButtonGroup} control.\end{methoddesc} \begin{methoddesc}[Dialog]{checkbox}{name, x, y, width, height,                                  attributes, property, text, next_control}  Add and return a \code{CheckBox} control.\end{methoddesc} \begin{seealso}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/dialog_table.asp]{Dialog Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/control_table.asp]{Control Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/controls.asp]{Control Types}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/controlcondition_table.asp]{ControlCondition Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/controlevent_table.asp]{ControlEvent Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/eventmapping_table.asp]{EventMapping Table}{}  \seetitle[http://msdn.microsoft.com/library/en-us/msi/setup/radiobutton_table.asp]{RadioButton Table}{}\end{seealso} \subsection{Precomputed tables\label{msi-tables}} \module{msilib} provides a few subpackages that containonly schema and table definitions. Currently, these definitionsare 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}
