* EncodeBuffer.cpp: add VALGRIND guardUlrich Sibiller2017-12-291-0/+7
| | | | | | | Same as in WriteBuffer.cpp Valgrind will complain about uninitialized data, but we are only writing to the memory here.

* nxcomp/src/Log.h: take a reference-type in generic has_newline() function.Mihai Moldovan2017-12-271-1/+1
| | | | Should avoid copy-constructing objects again.
* nxcomp/src/Log.cpp: don't confuse users with useless warning messages in ↵Mihai Moldovan2017-12-271-8/+12

* nxcomp/src/Log.h: make sure we don't pass NULL pointers to strstr().Mihai Moldovan2017-12-271-1/+8

| | | | | | | | | | | Especially don't flush data out mid-append. Doing so will lead to the next append operation failing. Should fix messages queuing up indefinitely (until they are discarded at program termination, at least) and missing messages in general.

* nxcomp/src/Log.{cpp,h}: provide infrastructure for appending to already ↵Mihai Moldovan2017-12-252-23/+89

* nx-X11/programs/Xserver/hw/nxagent/Screen.c: update screen size after ↵Mihai Moldovan2017-12-241-0/+7

* nx-libs.spec: make sure pass additional configure flags through, not discard ↵Mihai Moldovan2017-12-191-1/+2

| | | | | | | include stdlib.h and string.h for memset, malloc and free prototypes. Without that they are only implicitly defined - leading to build failures on *SUSE.

* nxcomp/src/Loop.cpp: log message fixups only.Mihai Moldovan2017-12-181-2/+2

* Drop SHMNAME workaround again, it *is* defined in shmstr.h, which is ↵Mihai Moldovan2017-12-163-8/+2

* nx-X11/programs/Xserver/Xext/shape.c: avoid pulling in Xlib in legacy mode ↵Mihai Moldovan2017-12-161-0/+7

* nx-X11/programs/Xserver/Xext/shape.c: pull in shapestr.h for legacy Xext ↵Mihai Moldovan2017-12-161-1/+1
| | | | proto versions, since shape.h would pull in Xlib.
* Handle SHAPE proto splitup gracefully for legacy Xext proto versions.Mihai Moldovan2017-12-161-0/+4
|
* zlib compatibility: whenever we want -I flags only, assume that the headers ↵Mihai Moldovan2017-12-162-3/+3
| | | | | | are directly available. Especially don't add linking flags willy-nilly.
* nx-X11/programs/Xserver/include/misc.h: add compat define for SHMNAME.Mihai Moldovan2017-12-161-0/+6
|
* Support building with legacy zlib versions that do not ship a pkg-config file.Mihai Moldovan2017-12-165-5/+23
