aMule r10874 freeze
« on: September 14, 2015, 08:23:06 PM »

Hi,
I'm using aMule svn built on debian stretch (actual testing). Follow details:
aMule svn r10874
gcc 5.2.1
wx 3.0.2
libcrypt 5.6.2

After 30 minutes of working deamon writes:

It continues to work for about 10 hours then upload drops to zero followed by download.

If you need additional testing I'm here.
Thanks for your work

Try compiling aMule with Boost.Asio (configure --with-boost). That should make the error disappear. aMule uses wxWidgets' networking library in a kind of non-standard way, and different wxWidgets versions (may) fail in different ways... However, for some people it just works :-)

@GonoszTopi: thanks for tip, I will try :)

New issue, trying to compile with boost:

avware@nas:/usr/src/amule$ ./configure --disable-monolithic --with-toolkit=base --enable-amule-daemon --with-boost
...
...
checking for <cxxabi.h> and __cxa_demangle()... yes
checking for Boost headers version >= 1.47.0... yes
checking for Boost's header version...
configure: error: invalid value: boost_major_version=

Maybe it depends to my compiler: gcc version 5.2.1 20150911 (Debian 5.2.1-17)
I found a post on github.com, suggests to use last version of boost.m4, but it never works.

Ok a I found a little workaround,
1) I commented this line on m4/boost.m4 file: AC_MSG_ERROR([invalid value: boost_major_version='$boost_major_version'])
2) Regenerated autoconf file with: ./autogen.sh
3) Configured with boost

Compile done with gcc5, now I'm testing amuled :)

What Boost version are you using?
It should be 1.58 (i'm on debian testing/stretch):

root@nas:~# dpkg-query --list | grep boost
ii  libboost-system-dev:amd64            1.58.0.1                          amd64        Operating system (e.g. diagnostics support) library (default version)
ii  libboost-system1.58-dev:amd64        1.58.0+dfsg-3                     amd64        Operating system (e.g. diagnostics support) library
ii  libboost-system1.58.0:amd64          1.58.0+dfsg-3                     amd64        Operating system (e.g. diagnostics support) library
ii  libboost1.58-dev:amd64               1.58.0+dfsg-3                     amd64        Boost C++ Libraries development files
ii  libtype-tiny-xs-perl                 0.012-1                           amd64        boost for some of Type::Tiny's built-in type constraints

Ok, I'll look into the problem (why it fails to properly detect the version number).

Hi,
I'm trying to understand what is the cause of assertion failed.

I changed these files:

#add signature to updownclient.h
void CUpDownClient::WriteLogPacketInfo(const byte* pachPacket, uint32 nSize)

#add procedure to BaseClient.cpp
void CUpDownClient::WriteLogPacketInfo(const byte* pachPacket, uint32 nSize)
{
            if (m_socket == NULL)
            {
                AddLogLineC(wxT("Socket is NULL"));
            }
            if (credits == NULL)
            {
                AddLogLineC(wxT("Credits is NULL"));
            }
            if (pachPacket[0] != nSize-1)
            {
                AddLogLineC(wxT("Packet size mismatch"));
            }
            if (nSize == 0)
            {
                AddLogLineC(wxT("Packet size is zero"));
            }
            if (nSize > 250)
            {
                AddLogLineC(wxT("Packet size greater than 250"));
            }
}

Row 2143 of BaseClient.cpp: add call to procedure
        if (m_socket == NULL || credits == NULL || pachPacket[0] != nSize-1
                || nSize == 0 || nSize > 250){
                WriteLogPacketInfo(pachPacket, nSize); <--
                wxFAIL;
                return;
        }
       
Row 2169 of BaseClient.cpp add call to procedure
        if (m_socket == NULL || credits == NULL || pachPacket[0] != nSize-1
                || nSize == 0 || nSize > 250){
                WriteLogPacketInfo(pachPacket, nSize); <--
                wxFAIL;
                return;
        }

I write a little more to see if it is a crashing bug or not.

All stacktraces are caused by:
!2015-09-26 16:19:10: BaseClient.cpp(2227): Packet size mismatch
!2015-09-26 16:19:10: BaseClient.cpp(2235): Packet size greater than 250

Maybe it's better don't write to the log in these two cases?

New issue, trying to compile with boost:

avware@nas:/usr/src/amule$ ./configure --disable-monolithic --with-toolkit=base --enable-amule-daemon --with-boost
...
...
checking for <cxxabi.h> and __cxa_demangle()... yes
checking for Boost headers version >= 1.47.0... yes
checking for Boost's header version...
configure: error: invalid value: boost_major_version=

Maybe it depends to my compiler: gcc version 5.2.1 20150911 (Debian 5.2.1-17)
I found a post on github.com, suggests to use last version of boost.m4, but it never works.

Ok, I don't know what the error was - it might be some Debian-specific change, or I don't know. For the error details config.log should have been examined.
Code: [Select]
checking for Boost headers version >= 1.47.0... /tmp/boost_1_58_0
checking for Boost's header version... 1_58

All stacktraces are caused by:
!2015-09-26 16:19:10: BaseClient.cpp(2227): Packet size mismatch
!2015-09-26 16:19:10: BaseClient.cpp(2235): Packet size greater than 250

Maybe it's better don't write to the log in these two cases?

Which leaves us with two cases: either a bogus client sends invalid packets, or there's something strange going on inside aMule.
