|
=head4 overall |
127 |
|
|
128 |
|
o try to get this stuff together with SyncML (http://syncml.org/) somehow ...? |
129 |

|
=head4 this code |
132 |
|
|
133 |
|
o sub _resolveIdentProvider |
134 |
|
x wrap _doModifySource and _doTransferTarget around a core function which can change virtually any type of node |
135 |
|
x split this module up into Sync.pm, Sync/Core.pm, Sync/Compare.pm and Sync/Compare/Checksum.pm |
136 |
|
o introduce _compareNodes as a core method and wrap it around methods in Sync/Compare/Checksum.pm |
137 |
|
x introduce Sync/Compare/MyComparisonImplementation.pm |
138 |
|
o some generic deferring method - e.g. "$self->defer(action)" - to be able to accumulate a bunch of actions for later processing |
139 |
|
- this implies everything done is _really_ split up into generic actions - how else would we defer them??? |
140 |
|
- example uses: |
141 |
|
- fetch whole checksum list from node |
142 |
|
- remember source ident retransmits |
143 |
|
- remember: this is convenient - and maybe / of course faster - but we'll loose "per-node-atomic" operations |
144 |
|
o feature: mechanism to implicit inject checksum property to nodes (alter table / modify schema) |
145 |
|
o expand statistics / keep track of: |
146 |
|
- touched/untouched nodes |
147 |
|
o full sync |
148 |
|
- just do a push and a pull for now but use stats for touched nodes in between to speed up things |
149 |
|
o introduce some new metadata flags for a descent |
