The functionality is not posix specific. Also force the usage of the
gdb-remote process plugin in the gdb platform class.
This is not sufficient to make TestPlatformConnect pass on windows (it
seems it suffers from module loading issues, unrelated to this test),
but it at least makes it shut down correctly, so I change the skip to an
xfail.
We have a plugin.process.gdb-remote.packet-timeout setting, which can be
used to control how long the lldb client is willing to wait before
declaring the server side dead. Our test suite makes use of this
feature, and sets the setting value fairly high, as the low default
value can cause flaky tests, particularly on slower bots.
After fixing TestPlatformConnect (one of the few tests exercising the
remote platform capabilities of lldb) in 4b284b9ca, it immediately
started being flaky on the arm bots. It turns out this is because the
packet-timeout setting is not being applied to platform connections.
This patch makes the platform connections also respect the value of this
setting. It also adds a test which checks that the timeout value is
being honored.
Differential Revision: https://reviews.llvm.org/D97769
Although it is located under tools/lldb-server, this test is very
different that other lldb-server tests. The most important distinction
is that it does not test lldb-server directly, but rather interacts with
it through the lldb client. It also tests the relevant client
functionality (the platform connect command, which is even admitted in
the test name). The fact that this test is structured as a lldb-server
test means it cannot access most of the goodies available to the
"normal" lldb tests (the runCmd function, which it reimplements; the
run_break_set_by_symbol utility function; etc.).
This patch makes it a full-fledged lldb this, and rewrites the relevant
bits to make use of the standard features. I also move the test into the
"commands" subtree to better reflect its new status.
