* Fix lldb-server test suite for python3Pavel Labath2019-02-151-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch finishes the python3-ification of the lldb-server test suite. It reverts the partial attempt in r352709 to encode/decode the string via utf8 before writing to the socket. This wasn't enough because the gdb-remote protocol can sometimes (but not very often) carry binary data, and the utf8 codec chokes on that. Instead I add utility functions to the "seven" module for performing "identity" transformations on the byte data. This basically drills back the hole in the python type system that the string/bytes distinction was supposed to plug. That is not ideal, but was the best solution of the alternatives I could come up with. The options I considered were: - make use of the type system to add type safety to the test suite: This required making a lot of changes to the test suite, since most of the strings would now become byte objects instead, and it was not even fully clear to me where to draw the line. One extreme solution would be to just use byte objects everywhere, as the protocol doesn't support non-ascii characters anyway. However, this appeared to be: a) weird, because most of the protocol actually deals with strings, but we would have to prefix everything with 'b' b) clunky, because the handling of the bytes objects is sufficiently different in PY2 and PY3 (e.g. b'a'[0] is a string in PY2, but an int in PY3). - using the latin1 codec (which gives an identity transformation for the first 256 code points of unicode) instead of the custom bytes_to_string functions. This almost could work, but it was still slightly different between python 2 and 3, because in PY2 in would return a unicode object, which would then cause problems when combined with regular strings if it contained 8-bit chars. With this in mind, I think the best solution for the time being is to just coerce everything into the string type as early as possible, and have things proceed indentically on both python versions. Once we stop supporting python3, we can revisit the idea of using bytes objects more prevasively.

* [testsuite] Remove trailing characters from command output.Jonas Devlieghere2019-01-281-1/+1
| | | | | | | | | | | | When running the test suite on macOS with Python 3 we noticed a difference in behavior between Python 2 and Python 3 for seven.get_command_output. The output contained a newline with Python 3, but not for Python 2. This resulted in an invalid SDK path passed to the compiler.

* *** This commit represents a complete reformatting of the LLDB source codeKate Stone2016-09-061-2/+7
| | | | | | | | | | | | | | | | | | | | | | | *** 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. llvm-svn: 280751
* Python 3 - Use universal_newlines when calling subprocess.check_outputZachary Turner2015-11-041-1/+1
| | | | | | | | | | | | | | | | | By default in Python 3, check_output() returns a program's output as an encoded byte sequence. This means it returns a Py3 `bytes` object, which cannot be compared to a string since it's a different fundamental type. Although it might not be correct from a purist standpoint, from a practical one we can assume that all output is encoded in the default locale, in which case using universal_newlines=True will decode it according to the current locale. Anyway, universal_newlines also has the nice behavior that it converts \r\n to \n on Windows platforms so this makes parsing code easier, should we need that. So it seems like a win/win. llvm-svn: 252025

* Create lldbsuite.support package with `seven` file.Zachary Turner2015-11-021-0/+17
This file will be useful for filling in the gaps where `six` is missing some things we need. llvm-svn: 251847
