The macro hardcodes libldap_r for OpenLDAP. OpenLDAP 2.5 and newer has eliminated the libdap_r library and merged that into libldap. I'm not sure how you would want to deal with that. The OpenBSD port just has a diff to s/ldap_r/ldap/ but of course something better is necessary
When I follow the README in plugins/sound_pulse
to let the audio tool report the available
sound devices, then I get the following error:

CentOS 8 4.18.0-240.10.1.el8_3.x86_64
Hello Jan,
it's over a year now since the last release and some important portability fixes have been merges since then.
Would you please be so kind to release a new version?
Thanks,
Gregor
We have an application that uses libh323plus to implement H323 signalling. When that application is shutting down, we are seeing that it hangs for about 10 seconds in H323ListenerTCP::Close()
, after which it aborts with an error "Listener thread did not terminate".
This only reproduces on a Kubuntu 21.10 x86_64 machine. It does not reproduce on other machines running Debian 10 or 11. It also did not reproduce previously on the same machine when it was running Kubuntu 21.04. So it looks like this issue is triggered by something that comes with Kubuntu 21.10.
I have prepared a reduced test case that reproduced the issue on Kubuntu 21.10.
The test case just creates a H323ListenerTCP
object with a single listener and waits for a keypress. Press Enter and it will attempt to terminate the listener and hang for 10 seconds, after which it will abort with the aforementioned error.
I have tried running the test under gdb and I can see that the code is waiting for the connection listening thread to terminate. I can see in gdb output that the thread actually terminates (gdb prints "[Thread 0x7ffff4f3d640 (LWP 133542) exited]" as soon as you press Enter), but the wait does not end until timeout. On timeout the process aborts with the following backtrace:
assert.cxx(114) PWLib Assertion fail: Listener thread did not terminate, file transports.cxx, line 1321, Error=20
Assertion fail: Listener thread did not terminate, file transports.cxx, line 1321, Error=20

I'm using ptlib 2.10.9.4 and libh323plus 1.27.2, both with minor patches updating build system and code for compatibility with our system (some of them are based on the upstream commits made after the released library versions). I'm fairly certain that the patches are not the problem as they have been tested before and don't cause problems on Debian.
I'm not quite sure if the problem is in ptlib or libh323plus, but it looks like threading code is in ptlib, and that is likely where the problem lies, hence I'm reporting it to ptlib.
ptlib/unix/ptlib/pmachdep.h:56:13: error: conflicting declaration 'typedef int socklen_t'
bits/alltypes.h:394:18: note: previous declaration as 'typedef unsigned int socklen_t' typedef unsigned socklen_t;
In commit 8772876, the signature of operator new[]
has been changed to include std::align_val_t
argument on a C++17 compiler. However, the signature of operator delete[]
was not changed and remains without the std::align_val_t
argument, which means it will not be called when the type of the object being deleted is over-aligned (i.e. when the overloaded operator new[]
was called to allocate it).
Furthermore, the operator new[]
does not use its std::align_val_t
argument to ensure that the allocated memory is actually aligned to the value of std::align_val_t
.
Relevant piece of code:
ptlib/src/ptlib/common/object.cxx
Lines 952 to 972 in c01afdc
Either both operator new[]
and operator delete[]
should accept (and use) the std::align_val_t
argument, or none should. Lastly, in order to use std::align_val_t
, <new>
must be included, and this include is missing in object.cxx
.
Relevant documentation for memory allocation functions:
https://en.cppreference.com/w/cpp/memory/new/operator_new
https://en.cppreference.com/w/cpp/memory/new/operator_delete
Line 434 in d2793c8
It causes segfault when compiled with PMEMORY_CHECK and PMemoryHeap::DumpObjectsSince() called after some threads were already deleted. Below is a patch which probably would be nice to apply :)
