Subject: fix for #213 restore old behaviour of --lazy. Even in lazy mode all the data
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d8890f9122d4d9db5abab6beacae8d4d779544b0;p=rrdtool.git

fix for #213 restore old behaviour of --lazy. Even in lazy mode all the data
calculation elements are run. The main time saving comes from the fact that
the graph is not being drawn and the image does not have to be compressed.

 Only generate the graph if the current graph is out of date or not existent.
-Note, that only the image size will be returned, if you run with lazy even
-when using graphv and even when using PRINT.
+Note, that all the calculations will happen regardless so that the output of
+PRINT and graphv will be complete regardless. Note that the behaviour of
+lazy in this regard has seen several changes over time. The only thing you
+can realy rely on before rrdtool 1.3.7 is that lazy will not generate the

+the size of the graph.
