version number

[Ren Wang <re...@gmail.com>]

Is there a way or API to set and get a file version number instead of
revision number? For my case, when a file is created, the version by default
should be 1, every change the version number will be incremented by 1.

 

Regards,

 

Ren

No, Subversion doesn't track files individually; it tracks changes, and a change can affect any number of files and directories.

Generally spoken this is a pretty simple matter:

[number of log entries for this file] == "version number"

Since your requirement is compatible enough that the number of log entries
directly corresponds to the version number, we now at least know that there
is no *extra* state data needed which would need to be stored in database
area.


As an svn semi-expert (insufficiently informed since SvnBridge devel), I
don't know which particular APIs might be available to retrieve this
information in the most direct/efficient manner, though.
You are likely looking for something
which directly returns a shallow "number of log entries"
rather than deep (per-entry) log information...

HTH,
