As some people met in Brussels on the eve of FOSDEM and talked about Wireshark,
here are some notes on what was talked about. We just don't want to leave anyone
out on what was talked about.
As usual: These are personal opinions etc, nothing is set in stone....
ciao
Jörg
Next release:
- we have interesting new features
+ multi interface capture:
o how will people feel about the additional click required to get to capture filter
o how well is it documented
+ default of pcap-ng
o new install: pcap-ng default
o update: keep
o put it prominently into the release notes
o unexpected behaviour, like mergecap - better error messages
+ Gerald may do some blog posts to introduce the new things to
warn users about the upcoming changes
+ gtk3 as default build
o proto_help
o audiograph problems
o tcp-graph: crosshairs not right
o menus lack frames
o gtk2 support on windows has problems as well (no current gtk 2.24 on win64)
o It's too early for making it default for 1.8
+ building Linux packages:
o Jörg will try to get a repo on obs for wireshark to provide packages
for many Linux distros (and offer an alternative with gtk2 and gtk3)
+ Must perform as well or better than the GTK2 version
- release timing
+ well before sharkfest, so people have used it
+ perhaps shortly after easter
+ April / May looks realistic
- we do too few *development* releases
+ do them more regularly (monthly/bi-monthly)
+ do feature releases
- backporting:
+ right now: using the wiki
o it's a lot of work
+ to make it easier: use a magic word in the commit message
Mesa uses: " NOTE: This is a candidate for the 7.11 branch."
and keep the wiki in case the note was forgotten (or enforce every
commit message to HEAD to have a #Backport: 0/1# part
+ can svn hooks help here?
+ Alternatively: give a level of importance for a backport instead of
just yes/no
Bugfixing:
- How do we handle all the old bugs?
- Maybe a top 5 bugs of the week
- Maybe a top 5 bugfixers of the week
- Maybe a testing/bugfixing weekend like Fedora/Ubuntu do
- Maybe Riverbed could hire someone to work on this
- Chris and Jeff seem to do quite a lot of triaging on the bugzilla
- can/should we make use of the voting mechanism in bugzilla?
Annotations:
- Martin has submitted a patch and wants to know whether he is on the
right track
- Is annotating packet #3 in a 4 GB file a problem?
Anonymizing:
- Two use cases:
+ Address anonymization
o replace everything of FT_IPv4 in memory
x more general: transformation function
o ftp, where ip-addresses are embedded in ascii-form
x needs special handling inside the dissector.
x for this particular problem: Maybe add an Encoding
type for it
o Print a csv file for the mapping
o maybe keep the last n bits as an option
+ Content anonymization
o Zero out elements that contain sensitive information, e.g.
credit card information, rtp: audio part
o Have an FT-type that declares that data is available to
anonymization
- Have a white list, zero out all protocol data that's not
on the whitelist
- Order of steps
+ First solve the prolbem of writing the changed data back to file
(take a look at the packeteditor feature)
+ Then discuss the rest.
How do display filters work:
- Nobody present here really understands how display filters work
qtshark:
- maybe we can attract a seasoned qt-developer to help us getting started
with the qtshark design stuff
cmake:
- on windows
+ cmake for VisualStudio would be welcome
+ Find out which features (scripts) are needed on windows
+ Graham is working on getting rid of the cygwin toolchain by writing
powershell replacements. If they are cross platform scripts, they
will be in python. The setup still requires the normal Windows
perl and python packages.
+ cmake would allow out-of-tree builds on Windows
+ starting with a cygwin/nmake alternative would be an idea as there is
no native windows / VisualStudio setup available right now.
iOS version:
- Probably not: Apple does not allow GPLed Software in the applestore:
http://michelf.com/weblog/2011/gpl-ios-app-store/
packet-x11.c:
- Copy the required includes into wireshark sources dissectors/x11/
git:
- Gerald will make the git repo official once he finds the time for it
- Moving to git will probably annoy lots of Windows users (tortoise git
is not comparable to tortoise svn).
- Are there tools to mirror out from git to svn?
- Create use cases for core and non-core developer use of git and svn,
then check whether these use cases can be fulfilled by running svn and
git-svn.
- If not, ask the core developers how they think about git - they are the
only ones that would be forced to interact with git, the rest could use a
svn mirror.
- non-core developers could benefit a lot from git, read-only access
is enough.
docbook:
- can we create one paper type that is compatible with both us and a4, so
we only have to build the pdfs once.
- the windows help files are deprecated by microsoft but the replacement
is not supported on xp
- we don't have oneline help on Unix/Linux/...
- Using a unified help format for all platforms? pdf with links?
- Is docbook really the right format or should the documentation be
moved to odf?
+ Svn has tools to unpack odf files so the diffs are still
visible on checkin.
+ Moving to odf would lower the barrier for most people who might
want to do documentation
+ Ask the people who contributed to the documentation what they think
about such a change.
- Jörg will add install targets and bug package maintainers to add ug and dg
to the packages.
wiretap plugins:
- plugins for reading proprietary packet formats are a good idea
- put an example and explanation into wiretap/README.plugin
- How to handle writing the (read-only) captures into a standard
format? Don't know.
- is there a 1:1 mapping between DLTs and WTAP_ENCAP_... ?
i10n:
- for the GUI OK
- for the dissectors not OK
- if someone wants to do it: don't stop him or her

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
