This is a rewrite of the command history facility of LLDB

It takes the history management out of the CommandInterpreter into its own CommandHistory class
It reimplements the command history command to allow more combinations of options to work correctly (e.g. com hist -c 1 -s 5)
It adds a new --wipe (-w) option to command history to allow clearing the history on demand
It extends the lldbtest runCmd: and expect: methods to allow adding commands to history if need be
It adds a test case for the reimplemented facility

- For instance, allows 'gcc' to match x86-64-linux-gnu-gcc as required on some Debian builds.
- Also adds doc-strings and a more consistent naming convention for related helpers.

llvm-svn: 183415

- one test case is due to llvm.org/pr16229
- other test case uses a Linux workaround for above by using os.fork() instead of subprocess module

llvm-svn: 183340

Adding support for stopping all threads of multithreaded inferiors on Linux.  Also adding multithreaded test cases.

llvm-svn: 182809

- Note that this is not correct, as the failure is associated with build options of libc.so, however it's failing on a Debian buildbot that uses gcc 4.6.2 (and the real goal is a complete backtrace even with -fomit-frame-pointer).

- Adds helpers to lldbtest.py to check the expectedCompiler and expectedVersion, with an eventual goal of reducing the number of test decorators.
--- Currently allows a comparison operator and a compiler version to be specified.
--- Can be extended to support ranges of compiler versions.

llvm-svn: 182155

- On Linux, the partial back-trace after an assert can cause the basic test to fail as discussed on lldb-dev.
- Uses SBFrame to walk up the stack to the assert site and tests expression evaluation of locals, globals and arguments.

Thanks to Daniel for review and testing on OS/X.

llvm-svn: 182115

- s/skipOnLinux/skipIfLinux/ to match style of every other decorator
- linkify bugizilla/PR numbers in comments

No intended change in functionality.

llvm-svn: 181913

llvm-svn: 181857

- older versions of clang are unable to include <chrono> from libstdc++
- skipping tests until buildbots are updated

llvm-svn: 181829

llvm-svn: 181341

llvm-svn: 181239

- moved build logic from Makefile and TestPublicAPIHeaders.py into lldbtest to allow reuse
- added decorator @skipIfi386

llvm-svn: 180955

-adds icc to the lit of compilers to run the tests
-adds icc test decorators
-skip TestAnonymous.py for icc

Fix the getCompilerVersion() function to do the right thing with clang 5.0 which now says "LLVM version" instead of "clang version".

llvm-svn: 176282

- pull up logic to get compiler version from TestUniqueTypes.py into lldbtest.py
- work around an GCC 4.6.3 issue

Fixing issues in previous checkin - still figuring out how to make expectedFailureClang take the bugnumber

llvm-svn: 175945

The decorators @expectedFailure (plain and special-case like i386, clang, ...) are modified to optionally take a bugnumber argument
If such an argument is specified, the failure report (or unexpected success report) will include the information passed in as part of the message
This is mostly useful for associating failures to issue IDs in issue management systems (e.g. the LLVM bugzilla)

llvm-svn: 175942

- replace "catch-all" except clause with one that specifically catches what pexpect throws
- handle case where child is already terminated (or is terminating) by the time tear-down is run

llvm-svn: 175844

- rework the way SBDebugger.SetAsync() is used to avoid side effects (reset original value at TearDownHook)
- refactor expectedFailureClang (and add expectedFailureGcc decorator)
- mark TestChangeValueAPI.py as expectedFailureGcc due to PR-15039

llvm-svn: 175523

- fixed cleanup of Popen objects by pushing spawn logic into test Base and out of test cases
- connect subprocess stdin to PIPE (rather than the parent's STDIN) to fix silent terminal issue

Tested on Linux and Mac OS X

llvm-svn: 175301

- set auto-confirm to false when running TestExprs (avoid hang when using API)
- set prompt-on-quit to false in test helper (avoid timeout when using lldb CLI)

llvm-svn: 173485

- Add new decorator "@skipIfGcc" to lldbtest.py

llvm-svn: 173394

The skipOnLinux decorator wasn't calling the test method correctly (no need to pass in the "self") resulting
in errors on MacOS X for the tests so decorated.

llvm-svn: 168662

- use lldb 'settings' command to help testcase find shared library
- pull up dyldPath variable from TestLoadUnload.py to fixture base class (applicable in multiple cases)

llvm-svn: 168612

- add decorators @expectedFailLinux and @skipOnLinux
- skip/mark xfail cases due to open bugzillas # 14323, 14416, 14423, 14424, 14425, 14426

<rdar://problem/12481949> Fixing SBValue.GetValueAsSigned() to do the right thing when dealing with a 32-bit negative value

llvm-svn: 166603

Changed all relevant test cases to verify that MightHaveChildren() works correctly for objects of interest
Added a bunch of convenience methods for test cases to use: target(), process(), thread() and frame() which mimic the lldb.X convenience variables
As a bonus, edited the documentation on the website to describe the new method available for synthetic children providers writers to implement!

That's all folks!

command line to dotest.py, replace / with _ in
the logfile names that mention that compiler so
that we don't try to put log files in weird
places.

llvm-svn: 166038

Fix all the test case breakages caused by folks writing tests all over the place that depended explicitly 
on the output of "break set".  Please don't do this sort of thing!!!!!

llvm-svn: 164433

This feature allows us to group test cases into logical groups (categories), and to only run a subset of test cases based on these categories.

Each test-case can have a new method getCategories(self): which returns a list of strings that are the categories to which the test case belongs.
If a test-case does not provide its own categories, we will look for categories in the class that contains the test case.
If that fails too, the default implementation looks for a .category file, which contains a comma separated list of strings.
The test suite will recurse look for .categories up until the top level directory (which we guarantee will have an empty .category file).

The driver dotest.py has a new --category <foo> option, which can be repeated, and specifies which categories of tests you want to run.
(example: ./dotest.py --category objc --category expression)

All tests that do not belong to any specified category will be skipped. Other filtering options still exist and should not interfere with category filtering.
A few tests have been categorized. Feel free to categorize others, and to suggest new categories that we could want to use.

All categories need to be validly defined in dotest.py, or the test suite will refuse to run when you use them as arguments to --category.

In the end, failures will be reported on a per-category basis, as well as in the usual format.

This is the very first stage of this feature. Feel free to chime in with ideas for improvements!

You run with trace mode by passing '-t' to the test driver.

llvm-svn: 161130

Adds a utility class method to TestBase that checks and removes a temp
file.
Removed every use of system() to execute rm -f.
