Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Jonas Devlieghere 72787ac661 Revert "[FileSystem] Make use of FS in TildeExpressionResolver"
The whole point of this change was making it possible to resolve paths
without depending on the FileSystem, which is not what I did here. Not
sure what I was thinking...

Jonas Devlieghere 9560f353ed [FileSystem] Make use of FS in TildeExpressionResolver
In order to call real_path from the TildeExpressionResolver we need
access to the FileSystem. Since the resolver lives under utility we have
to pass in the FS.

Frederic Riss 412f24dd2d Change TestCompletion to only ever look inside of BaseDir
TestCompletion was failing quite frequently on our Linux bots. Some tracing
revealed that when we are iterating BaseDir we are not getting all the entries.
More specifically, we are sometimes missing the entry corresponding to the
TestCompletion directory that the first test in DirCompletionAbsolute is
looking for. BaseDir is the directory where lit is creating all the temporary
files. The semantics of opendir/readdir are unclear when it comes to iterating
over a directory that changes contents, but it seems like on Linux you might
fail to list an entry even if it was there before opendir and is still present
throughout the iteration. Changing the test to only look inside of the test-
specific directory seems to fix the instability.

This commit also removes some assertions that were added to try to track down
this issue.

Frederic Riss 78a10a7a9b File completion bugfix
If you tried to complete somwthing like ~/., lldb would come up with a lot
of non-existent filenames by concatenating every exisitng file in the directory
with an initial '.'.

This was due to a workaround for an llvm::fs::path::filename behavior that
was not applied selectively enough.

Raphael Isemann 6328ccc14c Fixed windows bots that were failing because of PATH_MAX
As we only use PATH_MAX for an assert in a unit test that is supposed
to catch the random failures on the Swift CI bots, we might as well
just ifdef this assert out on Windows.

Raphael Isemann 3e1c793e9d Add more pre-run asserts for the DirCompletionAbsolute test
Summary:
The DirCompletionAbsolute is still randomly failing on the nodes even after D50722, so this patch adds more asserts
that verify certain properties on which the actual completion implementation relies on.

The first assert checks that the directory we complete on actually exists. If the directory doesn't exist on the
next CI failure, this assert should catch it and we know that the 0 matches come from a missing base directory.

The second assert is just checking that we are below the PATH_MAX limit that the completion checks against.
This check could randomly fail if the temporary directories we generate are sometimes longer than PATH_MAX,
and the assert can tell us that this is the reason we failed (instead of the mysterious '0 matches').

(As a sidenote: We shouldn't be checking against PATH_MAX anyway in the code (as this is just wrong). Also
the disk completion API really needs a better error mechanism than returning 0 on both error or no-results.)

Raphael Isemann ffa7010b8c Stability improvements for CompletionTest
Summary:
CompletionTest.DirCompletionAbsolute had a random failure on a CI node
(in the failure, the completion count was 0, while we expected it to be 1),
but there seems no good reason for it to fail. The sanitizers don't complain
about the test when it's run, so I think we don't have some uninitialized
memory that we access here.

My best bet is that the unique directory selection randomly failed on the CI
node because maybe the FS there doesn't actually guarantee the atomic fopen
assumptions we make in the LLVM code (or some other funny race condition).
In this case a different test run could get the same directory and clean its contents
which would lead to 0 results.

The other possible explanation is that someone changed the CI configuration
on the node and changed the working dir to something very long, which would
make our PATH_MAX test fail (which also leads to 0 results), but I think that case
is unlikely.

This patch is just a stab in the dark that (hopefully) fixes this random failure by
giving each test a (more) unique working directory by appending the unique
test name to the temp-dir prefix. Also adds one more ASSERT_NO_ERROR to
one of our chdir calls just in case that is the reason for failing.

The good thing is that this refactor gets rid of most of the static variables
and files that we previously had as shared state between the different tests.

Potentially fixes rdar://problem/43150260

Pavel Labath e17e9579eb Modernize completion tests
Now that we have gmock, we can use its matchers to better express the
test assertions. The main advantage of this is that when things fail,
the test will now print the expected and actual lists of completed
strings instead of just a not-very-helpful "false is not true" message.

Raphael Isemann 517c22041e Fix path completion test case added in rL335905 on Windows
Summary:
The test fails because we don't rewrite the slash behind `foo` to the OS specific
separator (as the completion API doesn't support this kind of rewriting). However,
we assume that this part of the string is rewritten in the test case, which broke
on Windows.

Zachary Turner 8d48cd6009 Resubmit "Delete the remainder of platform specific code in FileSpec."
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.

Pavel Labath bb114f84e7 Fix flakyness in TestCompletion
One of the file name templates was occasionally generating the name
"fooa***", which conflicted with the one of the tests expectation that
there is only one item beginning with "fooa".

There doesn't seem to be a good reason for using random file templates
here, so just switch to a fixed set of files to increase
reproducibility.

Zachary Turner d5bd3a1e6a Make file / directory completion work properly on Windows.
There were a couple of problems with this function on Windows. Different
separators and differences in how tilde expressions are resolved for
starters, but in addition there was no clear indication of what the
function's inputs or outputs were supposed to be, and there were no tests
to demonstrate its use.

To more easily paper over the differences between Windows paths,
non-Windows paths, and tilde expressions, I've ported this function to use
LLVM-based directory iteration (in fact, I would like to eliminate all of
LLDB's directory iteration code entirely since LLVM's is cleaner / more
efficient (i.e. it invokes fewer stat calls)). and llvm's portable path
manipulation library.

Since file and directory completion assumes you are referring to files and
directories on your local machine, it's safe to assume the path syntax
properties of the host in doing so, so LLVM's APIs are perfect for this.

I've also added a fairly robust set of unit tests. Since you can't really
predict what users will be on your machine, or what their home directories
will be, I added an interface called TildeExpressionResolver, and in the
unit test I've mocked up a fake implementation that acts like a unix
password database. This allows us to configure some fake users and home
directories in the test, so we can exercise all of those hard-to-test
codepaths that normally otherwise depend on the host.
