Please keep in mind that there are at least 3 different ways of building
libtorrent (boost-build, autotools and cmake). There are also a number of build
time configuration options (TORRENT_*
macros). If it may be relevant, please
include how libtorrent was built in your bug report.
boost-build is the authoritative build platform and autotools is the authoritative package tool. If there's a problem with a build script, please consider posting a pull request with a fix.
Please be explicit about the behavior you see, ideally boil it down to its essentials and provide example code, calling into libtorrent, reproducing the problem.
For bittorrent protocol level issues, please include session, torrent and peer level logs. The logs are available as alerts in libtorrent 1.1 and later (and have to be enabled).
For tracker issues, please include a wireshark dump of the tracker announce and response. It may be useful to also include session and torrent logs.
When creating a pull request, please consider the following checklist:
- make sure both travis-CI and appveyor builds are green. Note that on gcc and clang warnings are treated as errors. Some tests may be flapping, if so, please issue a rebuild of the specific build configuration. (I'm working on making all tests deterministic)
- please make sure to add appropriate comments. For client-facing changes, update the documentation comments in the public header (accepts restructured text)
- If adding a client-facing feature, please add brief entry to
ChangeLog
- Add a unit test (
tests
) or a regression test (simulations
) to confirm the new behavior or feature. Don't forget negative tests (failure cases) and please pay as much care to tests as you would production code. - if your patch adds a new .cpp file, please make sure it's added to the
appropriate
Jamfile
,Makefile.am
andCMakeList.txt
. If it's adding a header file, make sure it's added toinclude/libtorrent/Makefile.am
.
