One of the tests uses a child process which generates SIGSEGV.
On FreeBSD this generates a corefile by default which breaks
the 'make distcheck' process.
The Debian build farm has a number of older and slower machines
which need to run the xrdp test suite.
On these platforms, we occasionally get timeouts where machine load is
high. This results in duplicate issues being raised. It is not obvious
that the issues are duplicates, which wastes time all round.
This commit splits up some test cases into multiple cases and
adds larger timeouts for those cases that are CPU-intensive.
Rename g_file_open() to g_file_open_rw(), and add a new g_file_open_ro()
call that wraps the common g_file_open_ex(file, 1, 0, 0, 0) idiom. This
will make the file access mode more explicit in the code.
Change all calls to g_file_open() to the _ro() or _rw() variant as
appropriate, and replace g_file_open_ex(file, 1, 0, 0, 0) with the _ro()
call.
Lastly, add tests for the two new calls to test_os_calls.c (code
courteously provided by matt335672).
The semantics of this call allowed it to be called more than once when
parsing a message to restart a parse. This is not likely to be
useful in practice, and it also makes reading file descriptors
more complicated. Consequently this function has been removed and
replaced with with libipm_msg_in_get_msgno()
Normally the test runners run in 'forking mode'. When a lot of
messages are logged to stdout, the child process can still be writing
data when the parent writes 'ok' or 'not ok'. This can confuse
the tap-driver.sh process.
- Eliminate duplicaiton for display_size_description
- monitorCount needs to be uint32_t
- width/height -> session_width/session_height
- Update CLIENT_INFO_CURRENT_VERSION
- Also some misc unit test updates.
- Minor log updates.
There are two places where monitor descriptions are passed through the
RDP protocol:
- TS_UD_CS_MONITOR ([MS-RDPBCGR] 2.2.1.3.6 Client Monitor Data)
- DISPLAYCONTROL_PDU_TYPE_MONITOR_LAYOUT ([MS-RDPEDISP] 2.2.2.2)
The processing logic for both of them is similar enough that they should be unified.
Also update to define the constants for the maximum and minimum desktop width/height for monitors and total area.
Also a large number of clarifications for the constants and protocol
requirements.
Note that this is also the first step to making resizing work with the extension GFX channel as well as an important
foundational step to enable HiDPI compatibility.
Also some misc logging updates.
