|
---|
| 57 |
|
---|
| 58 | This is a proposal how to design Monitas before actually start the coding.
|
---|
| 59 | Collecting the ideas here will enforce to think about the structure before
|
---|
| 60 | it is realized in code that cannot be modified later.
|
---|
| 61 | With a little bit of luck this allows us to enhance Monitas' functionality
|
---|
| 62 | quite easy in the future.
|
---|
| 63 | And maybe we get a good user manual as side effect for free.

|
---|
| 73 | software
|
---|
| 74 | \emph default
|
---|
| 75 | that will be realized.
|
---|
| 76 | It is loosely based on the existing alpha version\SpecialChar ~
|
---|
| 77 | 0.1 of Monitas and shall
|
---|
| 78 | be a step by step approach towards Monitas version\SpecialChar ~
|
---|
| 79 | 0.99.
|
---|
| 80 | If improvements to Monitas v0.x and this document will be in sync, we will
|
---|
| 81 | have a good documentation of the internal system structure for Monitas\SpecialChar ~
|
---|
| 82 | v1.0
|
---|
| 83 | (and then this will be called Revision 2.0 of this document).
|
---|
| 84 | So in general the major revision number of the concept paper is 1 higher
|
---|
| 85 | than of the software, the minor revision numbers are both increasing but
|
---|
| 86 | there is no connection between the values.

|
---|
| 100 | Monitas is an extension to mondo/mindi to deal with remote backups between
|
---|
| 101 | TCP/IP connected PCs.
|
---|
| 102 | Monitas consists of two logical parts: a
|
---|
| 103 | \emph on
|
---|
| 104 | "client"
|
---|
| 105 | \emph default
|
---|
| 106 | that resides on the PC where the files (to backup/restore) are and a
|
---|
| 107 | \emph on
|
---|
| 108 | "server"
|
---|
| 109 | \emph default
|
---|
| 110 | on another (or the same) PC where the backup is stored.
|
---|
| 111 | \layout Standard
|
---|
| 112 |
|
---|
| 113 | The backup may be written to/read from a CD, to a file on a hard-disk (or
|
---|
| 114 | later to a revision controlled database).
|
---|
| 115 | \layout Standard
|
---|
| 116 |
|
---|
| 117 | Both together, server and client, will handle the backup and restore process
|
---|
| 118 | in the background.
|
---|
| 119 | Each is controlled via a pipe to send commands and to get status information
|
---|
| 120 | back (error messages, progress information).
|
---|
| 121 | Though it is possible to trigger the backup/restore process with these
|
---|
| 122 | interfaces, they are mainly designed for graphical (or text based) front-ends
|
---|
| 123 | which can dock there to control the process and interact with the user.
|
---|
| 124 | These front-ends aren't described here, but the syntax and semantics of
|
---|
| 125 | the interfaces.
|
---|
| 126 | \layout Standard
|
---|
| 127 |
|
---|
| 128 | We use a 1:
|
---|
| 129 | \emph on
|
---|
| 130 | n
|
---|
| 131 | \emph default
|
---|
| 132 | relation between the server and several clients on different PCs.
|
---|
| 133 | That means there exists only one central server that serves all the clients
|
---|
| 134 | out there.
|
---|
| 135 | \layout Standard
|
---|
| 136 |
|
---|
| 137 | Even if this document distinguishes between
|
---|
| 138 | \emph on
|
---|
| 139 | server
|
---|
| 140 | \emph default
|
---|
| 141 | and
|
---|
| 142 | \emph on
|
---|
| 143 | client
|
---|
| 144 | \emph default
|
---|
| 145 | and the different roles they play for the backup process, it is possible
|
---|
| 146 | that both parts use the same executable as both parts have much code in
|
---|
| 147 | common.
|
---|
| 148 | Like
|
---|
| 149 | \emph on
|
---|
| 150 | gzip
|
---|
| 151 | \emph default
|
---|
| 152 | , which is compressing when executed as
|
---|
| 153 | \family typewriter
|
---|
| 154 | gzip
|
---|
| 155 | \family default
|
---|
| 156 | and decompressing when executed as
|
---|
| 157 | \family typewriter
|
---|
| 158 | gunzip
|
---|
| 159 | \family default
|
---|
| 160 | , Monitas will run as server when executed as
|
---|
| 161 | \family typewriter
|
---|
| 162 | monitas_server
|
---|
| 163 | \family default
|
---|
| 164 | and will run as client when started as
|
---|
| 165 | \family typewriter
|
---|
| 166 | monitas_client
|
---|
| 167 | \family default

|
---|
| 356 | Monitas' functionality is mainly split into 2 independent parts: a
|
---|
| 357 | \emph on
|
---|
| 358 | client
|
---|
| 359 | \emph default
|
---|
| 360 | component on the PC where files are backuped or restored, and a

---|
| 361 | \emph on
|
---|
| 362 | server
|
---|
| 363 | \emph default
|
---|
| 364 | component to write the backup on an external medium or read previous backups
|
---|
| 365 | from an external medium.
|
---|
| 366 |
|
---|
| 367 | \layout Standard
|
---|
| 368 |
|
---|
| 369 | Both parts base on mondo/mindi for accessing files, doing (de)compression,
|
---|
| 370 | creating ISO-files, writing them to CD/DVD, \SpecialChar \ldots{}

| 397 | At startup, a client connects to the server process to establish the connection:
|
---|
| 398 | The client uses a predefined (

---|

| 406 | ) port where the server is listening.
|
---|
| 407 | When receiving a message at this port the server duplicates itself by using
|
---|
| 408 | the system call
|
---|
| 409 | \family typewriter
|
---|
| 410 | fork()
|
---|
| 411 | \family default
|

| 412 | or

---|
| 413 | \family typewriter
|
---|
| 414 | clone()
|
---|
| 415 | \family default
|
---|
| 416 | .
|
---|
| 417 | The child process will serve the connecting client on a new allocated port
|
---|
| 418 | and the parent process will continue waiting for further clients.
|
---|
| 419 | \layout Standard
|
---|
| 420 |
|
---|
| 421 | By that mechanism we need only one predefined port number and only on the
|
---|
| 422 | server PC.

|
---|
| 1643 |
|
---|
| 1644 | There is much work that is common to all the pipe interfaces that use text
|
---|
| 1645 | based messages: extract the command, calculate the number of mandatory
|
---|
| 1646 | parameters, split the arguments, parse for escape sequences, check if an
|
---|
| 1647 | arguments fits the requested type (e.g.
|
---|
| 1648 | filename, IP address, port number,\SpecialChar \ldots{}
|
---|
| 1649 | ), translate the textual argument into
|
---|
| 1650 | its machine readable format, \SpecialChar \ldots{}
|
---|
| 1651 | And equivalent steps are necessary when we
|
---|
| 1652 | want to create and send a message.
|
---|
| 1653 | And different commands use the same argument types that always must be
|
---|
| 1654 | parsed and checked in the same way.
|
---|
| 1655 | \layout Standard
|
---|
| 1656 |
|
---|
| 1657 | At the moment the extent of the complete command set cannot be given, so
|
---|
| 1658 | it would be the best to keep yet unknown extensions in mind and implement
|
---|
| 1659 | the pipe interface as a generic one:
|
---|
| 1660 | \layout Itemize
|
---|
| 1661 |
|
---|
| 1662 | use tables for valid commands (different tables for server- and client-pipes
|
---|
| 1663 | [or flags in a common table to ease common syntax for equivalent server/client
|
---|
| 1664 | commands?])

|

| 1708 | \layout Standard
|
---|
| 1709 |
|
---|
| 1710 | The tables can easily be extended and new commands can introduced with less
|
---|
| 1711 | effort by reusing existing subroutines for the argument handling.
|
---|
| 1712 | (B.t.w.
|
---|
| 1713 | the table contains all information that is necessary for an generic help
|
---|
| 1714 | function to each defined message.) Of course this only concerns the interface
|
---|
| 1715 | handling, not the new functionality.
|
---|
| 1716 | But why reinvent the wheel twice?
