This was causing a test failure in one of LLDB's tests which
specifically dealt with a limitation in LLVM's implementation
of home_directory() that LLDB's own implementation had worked
around.
This limitation has been addressed in r298513 on the LLVM side,
so the failing test (which is now unnecessary as the limitation
no longer exists) was removed in r298519, allowing this patch to
be re-submitted without modification.

getpwent is not available on android until API level 21, and even then
it is only available when doing a non-static link. Since android's
concept of users is very different from linux, it's doubtful the home
directory resolution would be useful, so I approximate this state by
just not using getpwent on android.
We've had another getpwent occurance in FileSpec for a while -- it
wasn't causing problems because it was stripped out by the linker, but I
disable that also, for consistency's sake.

FileSpec::EnumerateDirectory has a bunch of platform-specific
gunk in it for posix and non-posix platforms. We can get rid
of all this by using LLVM's easy-to-use directory iterators.

This was originall reverted due to some test failures in
ModuleCache and TestCompDirSymlink. These issues have all
been resolved and the code now passes all tests.

this reverts r297116 because it breaks the unittests and
TestCompDirSymlink. The ModuleCache unit test is trivially fixable, but
the CompDirSymlink failure is a symptom of a deeper problem: llvm's stat
functionality is not a drop-in replacement for lldb's. The former is
based on stat(2) (which does symlink resolution), while the latter is
based on lstat(2) (which does not).
This also reverts subsequent build fixes (r297128, r297120, 297117) and
r297119 (Remove FileSpec dependency on FileSystem) which builds on top
of this.

This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap. However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer. To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely. Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

This in turn triggered some fallout where other files had
been transitively picking up includes that they needed from
FileSpec.h, so I've fixed those up as well.

After a series of patches on the LLVM side to get the mmaping
code up to compatibility with LLDB's needs, it is now ready
to go, which means LLDB's custom mmapping code is redundant.
So this patch deletes it all and uses LLVM's code instead.
In the future, we could take this one step further and delete
even the lldb DataBuffer base class and rely entirely on
LLVM's facilities, but this is a job for another day.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

The unit test I added in the previous commit discovered a bug in
PrependPathComponent on windows -- it was calling SetFile with the host native
path syntax, whereas it should be explicitly specifying the path syntax (as
AppendPathComponent does). This fixes it.
llvm-svn: 292106
|
|
Summary:
PrependPathComponent was unconditionally inserting path separators between the
path components. This is not correct if the prepended path is "/", which caused
problems down the line. Fix the function to use the same algorithm as
AppendPathComponent and add a test. This fixes one part of llvm.org/pr31611.

This adds formatv-backed formatting functions in various
places in LLDB such as StreamString, logging, constructing
error messages, etc. A couple of callsites are changed
from Printf style syntax to formatv style syntax to
illustrate its usage. Additionally, a FileSpec formatter
is introduced so that FileSpecs can be formatted natively.

The core of the function was actually handling them correctly. However, the
early exit was being too optimistic and did not give the function a chance to
fire if the path did not contain dots as well.

Summary:
The only usage there was in GetModificationTime(). I also took the opportunity
to move this function from FileSpec to the FileSystem class - since we are
using FileSpecs to also represent remote files for which we cannot (easily)
retrieve modification time, it makes sense to make the decision to get the
modification time more explicit.
The new function returns a llvm::sys::TimePoint<>. To aid the transition
from TimeValue, I have added a constructor to it which enables implicit
conversion from a time_point.

Summary:
.. handling for windows path was completely broken because the function was
expecting \ as path separators, but we were passing it normalized file paths,
where these have been replaced by forward slashes. Apart from this, the function
was incorrect for posix paths as well in some corner cases, as well as being
generally hard to follow.
The corner cases were:
- /../bar -> should be same as /bar
- /bar/.. -> should be same as / (slightly dodgy as the former depends on /bar actually
existing, but since we're doing it in an abstract way, I think the
transformation is reasonable)
I rewrite the function to fix these corner cases and handle windows paths more
correctly. The function should now handle the posix paths (modulo symlinks, but
we cannot really do anything about that without a real filesystem). For windows
paths, there are a couple of corner cases left, mostly to do with drive letter
handling, which cannot be fixed until the rest of the class understands drive
letters better.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

environment and that might not always be set. Our FileSpec class uses this function to resolve any paths that start with "~/" on systems that support home directories as '~'. I have modified FileSpec::ResolveUsername (llvm::SmallVectorImpl<char> &path) to deal with the cases where llvm::sys::path::home_directory() returns false by digging a little further on unix systems and setting "HOME" in the environment so that subsequent calls to llvm::sys::path::home_directory() will succeed.
I also added a test to ensure we don't regress.

Summary:
In D18689, I removed the call to Normalize() in FileSpec::SetFile, because it no longer seemed
needed, and it resolved a quirk in the FileSpec API (spec.GetCString() returnes a path with
backslashes, but spec.GetDirectory().GetCString() has forward slashes). This turned out to be a
problem because we would consider paths with different separators as different (which led to
unresolved breakpoints for instance).
Here, I am putting back in the call to Normalize() and adding a unittest for FileSpec::Equal. I
am commenting out the GetDirectory unittests until we figure out the what is the expected
behaviour here.

Summary:
Even though FileSpec attempted to handle both kinds of path syntaxes (posix and windows) on both
platforms, it relied on the llvm path library to do its work, whose behavior differed on
different platforms. This led to subtle differences in FileSpec behavior between platforms. This
replaces the pieces of the llvm library with our own implementations. The functions are simply
copied from llvm, with #ifdefs replaced by runtime checks for ePathSyntaxWindows.

PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.

Paths on Windows are not case-sensitive. Because of this, if a file
is called main.cpp, you should be able to set a breakpoint on it
by using the name Main.cpp. In an ideal world, you could just
tell people to match the case, but in practice this can be a real
problem as it requires you to know whether the person who compiled
the program ran "clang++ main.cpp" or "clang++ Main.cpp", both of
which would work, regardless of what the file was actually called.

if "foo.txt" was appended to it. With this fix it will be:

We use the symbolic link to resolver to find the target of the LLDB shlib
symlink if there is a symlink. This allows us to find shlib-relative resources
even when running under the testsuite, where _lldb.so is a symlink in the Python
resource directory.
Also changed a comment to be slightly more clear about what resolve_path in the
constructor for FileSpec means, since if we were actually using realpath() this
code wouldn't have been necessary.

Fixes include:
- use FileSystem::Unlink() instead of a direct call to ::unlink(...) when deleting files when iterating through the current directory
- save directories from current directory in a list and iterate through those _after_ the current directory has been iterated
- Use new FileSpec::ForEachItemInDirectory() instead of manually iterating across directories with opendir()/readdir()/closedir()
We should switch all code over to using FileSpec::ForEachItemInDirectory(...) in the near future and get rid of FileSpec::EnumerateDirectory().
