Fixes#1259
If `ur_string_map_put ` fails then the string that was just `strdup`-ed
will leak memory
Now the return value is checked and memory free-ed in case of failure
- srandom/random provide stronger randomness characteristics than
srand/rand in some operating systems.
- usage of srand/rand is not very consistent in coturn.
There is room for more refactoring and use apputils helper functions in
ns_turn_msg.c too but i'm not sure that dependency from "client" module
to "apps" module is a good idea yet.
Thx @0xdea

Add missing checks for length of realm/nonce/server_name before copying
those values to the buffer passed to stun_is_challenge_response_str.
The function stun_is_challenge_response_str is only used in uclient test
application.
Thank you very much @0xdea

Fixes#823
When you try to delete an alternate server in the list by using "das :" command on the CLI, the session gets stuck and can't response although alternate server is removed.
The problem appears to be related to calling del_alt_server function in the same function recursively.

In some cases the prometheus server was started using SELECT even if
EPOLL was supported.
Some flags were changed in microhttpd and now we use MHD_VERSION to make
sure to use the right ones in all cases (support old version, for ubuntu
16.04 for ex).
This fixes the issue #1167
I also added a log to make sure we know which version is used,
especially to inform the user that the SELECT version might lead to
issues on highly used servers.
PR #855 introduced new include <ssys/sysinfo.h>
It is not required for compilation or turnserver function but breaks
OpenBSD build (which does not have this file)
This PR removes the include to restore OpenBSD build compatibility
Fixes#1162
Test Plan:
TBD - need some one to test build
There is no reason to include the license of openssl - coturn uses openssl just like any other library
As a reference - Apache httpd does not have openssl license
#1049
MacOS CI build started to fail in the PRs because when upgrading python
it was not possible to override one existing file (related to 2to3
package). Apparently this happens because MacOS runners some times have
python versions not installed/compatible with brew.
Example of the failure:
https://github.com/coturn/coturn/actions/runs/3850951324
The proposed workaround is taken from here:
https://github.com/actions/runner-images/issues/2322
This pull request is a split of PR #1061
As @KangLin pointed out in the original PR those sockets should ideally
be permanently non-blocking for performance reasons, but they are NOT at
the moment.
Someone with more knowledge about the code in dtls_listener.c should
probably have a look if it would be feasible to change the sockets to
non-blocking already at creation, similar to what is done in
udpserver.c...
Add some basic contributing guidelines based (almost cloned) on the
Redis ones.
There were some questions about how to contribute and get started with
the project. I see this type of document in other projects that I think
can be useful.
This is not a long term documentation works - this is a temp proposal to
modernize existing documentation
- Create docs folder
- Move existing documentation files into docs
- Split one massive INSTALL files into smaller files (no text editing
was done except small markdown header formatting)
- Rename files to be markdowns for nicer rendering
- Bad md rendering is expected in many places
