Re: Structures change in versions

As far as I know we do attempt to freeze the API for minor versions; I
believe we even have a build script that is supposed to catch such
breakages and report them. I wonder why it did not catch this one?

Hello,

I recently found out that the frame_data structure had a minor change in the
1.8 branch between 1.8.8 and 1.8.9:
https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blobdiff;f=epan/frame_data.h;h=5ab320541760d412a11ad23422e29b8b8e88635e;hp=dc4f177a34f5a1cd00c2d754f63440301db42f09;hb=0a28fb8f6a354aa9a446b6bf70733c305534e074;hpb=27b5d556cb53bee24e20a9bb5862189ee2e55a61

Unfortunately, this minor change broke my plugin's (pyreshark) interfacing
with Wireshark, with a fix requiring either having two versions for the 1.8
branch (I currently provide a single version of the plugin for every minor
version (1.8, 1.10) of Wireshark) or adding some ugly hack to determine the
version during runtime.

While I can't say it's critical, as I only discovered this change nearly a
year after it was introduced, I do see merit in freezing the API in minor
versions, to keep plugin versions at a minimum.

I apologise if the above seems accusative, I'm not a native English speaker,
so my words might have conveyed the wrong message. My intention was to bring
this issue to your attention with the hope that in the future you'll take it
into consideration during future development.

Thanks for all your hard work!
Eshed
