=head2 hmm..... |
| 13 |
|
| 14 |
A Command is a Request. |
| 15 |
A Task is a Process. |
| 16 |
A Request is a Command. |
| 17 |
A Process is a Task. |
| 18 |
There are just details. |
| 19 |
|
| 20 |
=head2 ahh... |
| 21 |
|
| 22 |
CPAN already *has got* all the tools starting an attempt to do this. |
| 23 |
|
| 24 |
Having enough experience with Perl now, this attempt should work out well..... |
| 25 |
But still, Hmmm...... |
| 26 |
And: lots of work, i believe.... |
| 27 |
|
| 28 |
Okay: |
| 29 |
Look at DesignPattern:: and Data::Transform::Deep & Co. (lowlevel stuff) |
| 30 |
or OEF::, Data::Storage and Data::Transfer::Sync (highlevel stuff). |
| 31 |
|
| 32 |
And then: |
| 33 |
|
| 34 |
|
| 35 |
=head1 Overview |
| 36 |
|
| 37 |
=head2 Rap - Request And Process |
| 38 |
|
| 39 |
|
| 40 |
=head3 Rap's aims are directed to get some of this together |
| 41 |
|
| 42 |
- some concepts of make (->targets) |
| 43 |
- some concepts of ant (->tasks) |
| 44 |
- some code written while developing a custom application with Perl: |
| 45 |
- libraries/modules (CPAN proposals) |
| 46 |
- Data::Storage::Container |
| 47 |
- Data::Storage |
| 48 |
- Data::Transfer::Sync |
| 49 |
- OEF::Component::Task |
| 50 |
- make "old" shortcut programs like "feed.pl", "tell.pl" and such obsolete |
| 51 |
- add more targets in order to make "setup.pl" & Co. obsolete as well |
| 52 |
|
| 53 |
|
| 54 |
=head3 It's using these fine modules from CPAN |
| 55 |
|
| 56 |
- xml, xpath and such (XML::Parser, XML::XPath) |
| 57 |
- local os native (background) process execution (IPC::Run) |
| 58 |
- remote procedure calls with xml payloads: XMLRPC, SOAP and such (RPC::XML, SOAP::Lite) |
| 59 |
- configuration- and property-data inheritance: Hash::Merge |
| 60 |
|
| 61 |
- under the hood: |
| 62 |
- logging: Log::Dispatch |
| 63 |
- data-access: DBI & Co., Tangram |
| 64 |
- data-manipulation: Data::Dumper, Iterate |
| 65 |
- in other words: all modules already included in some declaration inside 'setup.pl' |
| 66 |
|
| 67 |
|
| 68 |
=head3 Rap does networking |
| 69 |
|
| 70 |
- It's a client. (cli program, standalone) |
| 71 |
- It's a server/daemon as well. (cli interacts with daemon via tcp-socket) |
| 72 |
|
| 73 |
|
| 74 |
=head3 Rap is open for enhancements and/or integration into/with other stuff |
| 75 |
|
| 76 |
=head4 Command-Frontends (local and/or remote) |
| 77 |
|
| 78 |
o Commands can be sent via psh (The Perl Shell) or similar frontends (via rap.pl or Rap.pm) |
| 79 |
o Commands can be issued from a php-frontend (via RPC using Rap::) |
| 80 |
|
| 81 |
=head4 Target-Registry (local and/or remote) |
| 82 |
|
| 83 |
x Targets can be defined inside a rap.xml or similar |
| 84 |
o Targets can be stored in arbitrary data structures (e.g. read from an rdbms or ldap-storage) |
| 85 |
|
| 86 |
=head4 Task-Backends (local and/or remote) |
| 87 |
|
| 88 |
x Tasks can run as local native processes (attached and/or background) |
| 89 |
o Tasks can be triggered by issuing RPC-calls to arbitrary multiple hosts |
| 90 |
|
| 91 |
=head4 TODO |
| 92 |
o look at Maven's POM (Project Object Model): |
| 93 |
- http://jakarta.apache.org/turbine/maven/reference/project-descriptor.html |
| 94 |
- http://jakarta.apache.org/turbine/maven/images/project-descriptor.gif |
| 95 |
- http://jakarta.apache.org/turbine/maven/start/integrate.html |
| 96 |
- http://jakarta.apache.org/turbine/maven/reference/dirlayout.html |
| 97 |
o integrate with: |
| 98 |
o POE |
| 99 |
o PP5E |
| 100 |
o integrate with pod (for reporting purposes) |
| 101 |
o look at: |
| 102 |
btw: "expand": look at scripts@CPAN (System Administration): |
| 103 |
there is a perl make with perl |
| 104 |
o refactore child-modules using code from Data::Code only! |
