The LoadScriptingModule used by command script import wasn't
initializing the LLDB global variables (things like `lldb.frame` and
`lldb.debugger`). They would get initialized however when running the
interactive script interpreter or running a single script line (e.g.
`script print(lldb.frame)`). This patch fixes that by properly
initializing the globals when loading a Python module.

This reverts commit 21641a2f6d.
It was causing the following test failures:

lldb-Suite.lang/objc/foundation.TestObjCMethodsString.py
lldb-Suite.lang/objc/foundation.TestConstStrings.py

This test is failing on the Fedora bot (staging). Rather than failing
with an IndexError, we should trigger an assert and dump the log when
the regex doesn't match.

Summary:
The path defined in CMakeLists.txt doesn't match the path generated in
our python script. This change fixes that.
LLVM_LIBRARY_OUTPUT_INTDIR is defined as:
${CMAKE_BINARY_DIR}/${CMAKE_CFG_INTDIR}/lib${LLVM_LIBDIR_SUFFIX})
On the other hand, the path of site-package is generaged in
get_framework_python_dir_windows() in finishSwigPythonLLDB.py as:
(Dispite its name, the function is used for everything other than xcode)
prefix/cmakeBuildConfiguration/distutils.sysconfig.get_python_lib()
From lldb/CMakeLists.txt, we can see that:
prefix=${CMAKE_BINARY_DIR},
cmakeBuildConfiguration=${CMAKE_CFG_INTDIR}
And from python source code, we can see get_python_lib() always returns
lib/pythonx.y/site-packages for posix, or Lib/site-packages for windows:
https://github.com/python/cpython/blob/3.8/Lib/distutils/sysconfig.py#L128
We should make them match each other.

This patch completes the dump functionality by adding support for
dumping a reproducer's GDB remote packets.
Differential revision: https://reviews.llvm.org/D67636
llvm-svn: 372046
This moves the dumping logic from the GDBRemoteCommunicationHistory
class into the GDBRemotePacket so that it can be reused from the
reproducer command object.
llvm-svn: 372028
Summary:
These functions are only used in tests where we should test the actual flag values instead of counting all bits for an approximate check.
Also these popcount implementation aren't very efficient and doesn't seem to be optimised to anything fast.

This adds a reproducer dump commands which makes it possible to inspect
a reproducer from inside LLDB. Currently it supports the Files, Commands
and Version providers. I'm planning to add support for the GDB Remote
provider in a follow-up patch.

To support dumping the reproducer's GDB remote packets, we need the
(de)serialization logic to live in Utility rather than the GDB remote
plugin. This patch renames StreamGDBRemote to GDBRemote and moves the
relevant packet code there.
Its uses in the GDBRemoteCommunicationHistory and the
GDBRemoteCommunicationReplayServer are updated as well.

This ensures that if the assertion fails we dump the log content. This
should help me investigate what the output looks like on Windows, where
the test is failing.

The new centralized way of doing API logging through the reproducer
macros is lacking a way to easily correlate instances of API objects.
Logging the this pointer makes that significantly easier. For methods
this is now always passed as the first argument, similar to the self
argument in Python.
This patch also adds a test case for API logging, which uncovered that
we were not quoting strings.
Differential revision: https://reviews.llvm.org/D67538
llvm-svn: 371885
The StringRef should always be identical to the C string, so we
might as well just create the StringRef from the C-string. This
might be slightly slower until we implement the storage of ArgEntry
with a string instead of a std::unique_ptr<char[]>. Until then we
have to do the additional strlen on the C string to construct the
StringRef.
llvm-svn: 371842
This code is not on any performance critical path that would
justify this shortening optimization. It also makes it possible
to turn 'ref' into a function (as this is the only place where
we modify this ArgEntry member).
llvm-svn: 371836
levels:
-- none: no lax vector conversions [new GCC default]
-- integer: only conversions between integer vectors [old GCC default]
-- all: all conversions between same-size vectors [Clang default]
For now, Clang still defaults to "all" mode, but per my proposal on
cfe-dev (2019-04-10) the default will be changed to "integer" as soon as
that doesn't break lots of testcases. (Eventually I'd like to change the
default to "none" to match GCC and general sanity.)
Following GCC's behavior, the driver flag -flax-vector-conversions is
translated to -flax-vector-conversions=integer.
This reinstates r371805, reverted in r371813, with an additional fix for
lldb.

Summary:
InferiorCall is only ever used in Process, and it is not specific to
POSIX. By moving it to Process, we can remove all dependencies on plugins from
Process. Moving InferiorCall to Process seems to achieve this quite well.
Additionally, the name InferiorCall is a little vague now, so we rename
it something a bit more specific.

These tests were temporarily missing when the big Makefile
simplification patch landed, so this just applies the same change
to these tests.
llvm-svn: 371738
After reverting the deletion of the functionalities/breakpoint tests,
we now have some tests twice in the test/ folder which breaks dotest:
* commands/breakpoint/basic
* functionalities/breakpoint/breakpoint_command
After looking over these tests, I think it makes sense to only
keep the original functionalities/ folder. The commands/breakpoint/basic
test are not exclusively testing the breakpoint command itself, so
they shouldn't be in commands/ in the first place. Note that these
folders have identical contents (beside small adjustments regarding
the Makefile which landed after the restructuring).

This just moves the CommandLoader utility into the reproducer namespace
and makes it accessible outside the API layer. This is setting things up
for a bigger change.

Originally the idea was for providers to be defined close to where they
are used. While this helped designing the providers in such a way that
they don't depend on each other, it also means that it's not possible to
access them from a central place. This proved to be a problem for some
providers and resulted in them living in the reproducer class.
The ProcessGDBRemote provider is the last remaining exception. This
patch makes things consistent and moves it into the reproducer like the
other providers.

Summary:
InferiorCallPOSIX directly grabs a ClangASTContext from the Target it
has and does no error checking. I don't think these functions have a
reason to know about clang specifically. Additionally, using
`GetScratchTypeSystemForLanguage` forces us to do error checking since
it returns an Expected.

We never compare these directories (where ConstString would be good) and
essentially just convert this back to a normal string in the end. So we might
as well just use std::string. Also makes it easier to unittest this code
(which was the main motivation for this change).
llvm-svn: 371623
Summary:
This change ensures that the .dynsym section will be parsed even when there's already is a .symtab.
It is motivated because of minidebuginfo (https://sourceware.org/gdb/current/onlinedocs/gdb/MiniDebugInfo.html#MiniDebugInfo).
There it says:
Keep all the function symbols not already in the dynamic symbol table.
That means the .symtab embedded inside the .gnu_debugdata does NOT contain the symbols from .dynsym. But in order to put a breakpoint on all symbols we need to load both. I hope this makes sense.
My other patch D66791 implements support for minidebuginfo, that's why I need this change.

This code is trying too hard and failing. Either the result of
gethostname() is canonical or it is not. If it is not, then trying to
canonicalize it is – for various reasons – a lost cause. For example, a
given machine might have multiple network interfaces with multiple
addresses per interface, each with a different canonical name.
Separably, the result of HostInfoPosix::GetHostname() and latency
thereof shouldn't depend on whether networking is up or down or what
network the machine happened to be attached to at any given moment (like
a laptop that travels between work and home).
