[Dextrose] [sugar-toolkit PATCH] sl#3317: Batch Operations on Journal Entries (Copy, Erase)

[Sascha Silbe]

Excerpts from Ajay Garg's message of 2012-02-05 21:47:47 +0100:


The patch summary (subject line) doesn't describe what this patch does,
only in what context it is useful.

Also, please note that sugar-toolkit (GTK2) is in maintenance mode; API
changes need to be targeted at sugar-toolkit-gtk3. For changes that are
required by the sugar package (which is still based on sugar-toolkit),
we may make an exemption and backport them to sugar-toolkit, but they
need to get landed in sugar-toolkit-gtk3 first.

I don't grok your description and I don't see a use case, given that all
you do...

... is to add an optional gobject.idle_add() invocation with parameters
passed in by the caller. Why don't you simply do that on the caller
side?

We can't account for everything some caller might want to do after
executing this method, that would litter the code with special cases and
make it incomprehensible. There needs to be some real value gained from
doing it as part of the API.
