This library contains all the code for the old libtoxcore, libtoxav,
libtoxdns, and libtoxencryptsave. The build for toxav is still optional,
and disabling it causes libtoxcore to simply not contain those symbols
and the pkg-config file to not include opus and vpx as dependencies.
Tests are not actually ran on appveyor for now, since they all fault for
some reason. For now, we just build them. Also, some tests are disabled
on msvc entirely, because they don't even compile. We'll need to look
into those, later. They are disabled using `MSVC_DONT_BUILD`.
This requires that every symbol, even if static (file-scope), is unique.
The idea is that we can easily run "whole" program static analysis on
programs that include monolith.h ("whole" is in quotes, as we don't
include dependencies like libsodium in this static analysis).
Also a little bit of refactoring:
- Moved add_cflag and friends from CMakeLists.txt to a separate
AddCompilerFlag module.
- Build the spectest SUT if msgpack is found, even if spectest itself is
not found, so once it exists, users can run it themselves or
reconfigure cmake.
this updates the version-sync script to generate proper SO versions
which will be used by cmake and libtool to create version symlinks
on the system when a library is installed as well as setting the SO
version in the binary.
To see what this does, you have to configure tox with a prefix:
./configure --prefix=/tmp/tox-with-libtool
mkdir cbuild && cd cbuild && cmake -DCMAKE_INSTALL_PREFIX=/tmp/tox-with-cmake ..
Then run `make && make install`.
in both instances you should see the following installed in `lib/`:
libtoxcore.so -> libtoxcore.so.1.4.0
libtoxcore.so.1 -> libtoxcore.so.1.4.0
libtoxcore.so.1.4.0
inside the binary the soname should be the one with .1 and it should not
contain the full version:
$ objdump -p libtoxcore.so.1.4.0 | grep SONAME
SONAME libtoxcore.so.1
- CFLAG gnu99 was changed to c99.
- CXXFLAG c++98 was changed to c++11.
- CFLAG -pedantic-errors was added so that non-ISO C now throws errors.
- _XOPEN_SOURCE feature test macro added and set to 600 to expose SUSv3
and c99 definitions in modules that required them.
- Fixed tests (and bootstrap daemon logging) that were failing due to
the altered build flags.
- Avoid string suffix misinterpretation; explicit narrowing conversion.
- Misc. additions to .gitignore to make sure build artifacts don't wind
up in version control.
This was just for finding it in toktok-stack, which now uses
haskell-stack, and thus no longer has a .cabal-sandbox. We'll just assume
that the Makefile properly sets up the path such that tox-spectest is
available.
The CMAKE_SOURCE_DIR variable points to the top-level directory of a project while we want to point to the top-level directory of the lib. This change simplifies the integration as a third-party lib. We can use CMAKE_CURRENT_SOURCE_DIR or simply "nothing" ('.') to point to the directory where the CMakeLists.txt file resides.
Also added a `tox_options_copy` function for cloning an options object.
This can be useful when creating several Tox instances with slightly
varying options.
We create and destroy 20k tox instances and run a single tox_iterate on
it. This test is not comprehensive, but provides a simple check to see
whether the destruction properly cleans up memory and perhaps other
resources.
These were generated by the autotools build. Some clients may depend on
these files instead of the newer split pkg-config files. New clients
should be using the toxcore, toxav, toxencryptsave, and toxdns modules.
Having -Werror set by default causes users' builds to fail because
toxcore is not warning-free. Failing on errors is appropriate for the
development phase, e.g. when building it in a CI enviroment, but it
doesn't make much sense to fail builds for users and let them figure out
that they need to pass -DWARNINGS=OFF to make the library build.
This warning is triggered in `av_test.c`, where we have an open issue.
Silencing the warning locally would make the issue less visible. This
way, we will see the warning when we start removing the `-Wno-*` flags.
Also, disable -pedantic on C++, because it's not really useful there,
and causes a lot of warnings on `enum FOO { BAR, };` (comma at end of
enumerator list).
We disable the ones that fire, so we can use -Werror. We can then
investigate each warning individually and see whether to fix it or to
keep silencing it.
Compiling as C++ changes nothing semantically, but ensures that we don't
break C++ compatibility while also retaining C compatibility.
C++ compatibility is useful for tooling and additional diagnostics and
analyses.
We use TRACE=ON (cmake flag) to enable LOG_TRACE. This way, a regular
build can enable DEBUG while not paying the price of TRACE. This is
particularly important for FFI bindings (especially Python), where
invoking callbacks can be an expensive operation.
When cross-compiling to <target> from Linux, cmake might find native Linux
libconfig and decide to build tox-bootstrapd. If the target is Windows, this
will fail, as tox-bootstrapd can't be built for Windows in the first place. If
the target is Linux of some other architecture, then using host native
libconfig will fail too. Thus an option is needed to guard against this.
- Moved apidsl headers next to their generated versions. In the future,
perhaps all (or most) headers will be apidsl-generated, so the sources
should stay together.
- Try to find apidsl/apigen binary and astyle binary and use it for the
format test. Don't run the format test if these can't be found.
All tests must end in `_test` so we can use this convention to slightly
shorten the names in `auto_test` calls. This also enforces the
convention so future tests obey it.
It is still C code, so still compatible with C compilers as well. This
change lets us see more clearly where implicit conversions occur by
making them explicit.
`tox_options_[gs]et_ipv6_enabled` were missing from the version script
because the grep expression only accepted `[a-z_]`. Now it also accepts
digits in the function names.
Enabling this flag will generate and use an LD version script. It
ensures that the dynamic libraries (libtoxcore.so, libtoxav.so) only
export the symbols that are defined in their public API (tox.h and
toxav.h, respectively).
Also, no longer #include the group code into tox.c. Instead, compile it
separately in tox_group.c. This is a bit less surprising to someone looking
around the code. Having some implementations in a .h file is certainly a bit
surprising to a disciplined C programmer, especially when there is no technical
reason to do it.
This removes the global logger (which by the way was deleted when the first tox
was killed, so other toxes would then stop logging). Various bits of the code
now carry a logger or pass it around. It's a bit less transparent now, but now
there is no need to have a global logger, and clients can decide what to log and
where.
The threading networking functions (on windows: winsock and friends) need to be
linked into the toxnetwork library, not the toxcore library, anymore. On Linux
and OSX, there is no winsock. On OSX, there is no need to link against threading
libraries, and on Linux, toxnetwork can have unresolved symbols when linking, so
this failure wasn't caught before.
Tested by building on the iphydf/windows-x86-qt5 docker image.
- This PR also adds a DEBUG cmake option that enables -DTOX_DEBUG.
- We also remove `-Wall`, because there are too many warnings, and nobody really
looks at them at the moment. We'll see about fixing them soon. We'll also want
to enable `-Werror` at some point.
- Finally, this PR enables `-O3` to make sure toxcore still works correctly
under heavy compiler optimisations.
This allows us to more clearly define interfaces between modules, and have the
linker help us ensure that module boundaries are respected.
The onion/tcp/net_crypto layer is a bit too large. This is due to a cyclic
dependency (onion -> net_crypto -> TCP -> onion). We may or may not want to
break that cycle in the future to allow the onion library to exist on its own
without net_crypto.
Also, fix the hstox build that was taking half an hour. It now takes 5 minutes.
Also, perform distcheck on travis to ensure that make dist works. It's not
actually failing the build at the moment due to broken tests.
While doing the checks configure might generate "core" files and will
then try to remove them. Having a "core" directory generates an error
while runing the configure script.
There's no workaround but to rename the core directory.
Added crypto to the DHT communications.
This defeats completely the first attack mentioned in
docs/DHT_hardening.
Also updated the build system to build the latest test (it links it with
libsodium)
