The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior

dematerialization of registers that caused
conditional breakpoint expressions not to
work properly. Also added a testcase.

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

- skip the attach cases in TestRegisters.py -- caused slowness/sigabrt
- fixed log file removal function (in case test is run with -# flag)

Modified the test programs to use floating point constants that always will display correctly. We had some numbers that were being rounded, and now that we are using clang, we no longer round them and we get more correct results.

that is patterned after its parent TestInferiorCrashing.py.
- The xfail decorator limits the xfail to tool-chains that support this compiler option.
- Included a TODO concerning the platform-specific behavior when 'next' is issued after a crash.
- Toggling -fomit-frame-pointer results in an xpass as mentioned in pr15415.
Thanks to Daniel for the review, and Samuel for the bug report and reproducer.

- 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

Adding data formatters for std::set, std::multiset and std::multimap for libc++
The underlying data structure is the same as std::map, so this change is very minimal and mostly consists of test cases
llvm-svn: 183323
If you want to define a formatter for "array of Foo of any size", ordinarily you would say
-x "Foo \[[0-9]+\]"
this checkin allows you to instead say "Foo[]" (or "Foo []") and LLDB will automatically create the regular expression and add the -x flag on your behalf
llvm-svn: 183272
Fixing an issue where formats would not propagate from parents to children in all cases
Details follow:
an SBValue has children and those are fetched along with their values
Now, one calls SBValue::SetFormat() on the parent
Technically, the format choices should propagate onto the children (see ValueObject::GetFormat())
But if the children values are already fetched, they won't notice the format change and won't update themselves
This commit fixes that by making ValueObject::GetValueAsCString() check if any format change intervened from the previous call to the current one
A test case is also added

command script import now does reloads - for real
If you invoke command script import foo and it detects that foo has already been imported, it will
- invoke reload(foo) to reload the module in Python
- re-invoke foo.__lldb_init_module
This second step is necessary to ensure that LLDB does not keep cached copies of any formatter, command, ... that the module is providing
Usual caveats with Python imports persist. Among these:
- if you have objects lurking around, reloading the module won't magically update them to reflect changes
- if module A imports module B, reloading A won't reload B
These are Python-specific issues independent of LLDB that would require more extensive design work
The --allow-reload (-r) option is maintained for compatibility with existing scripts, but is clearly documented as redundant - reloading is always enabled whether you use it or not

- The original test now passes on Linux with clang because a breakpoint is hit prior to evaluation of text_list, which improves text coverage.
- The new test fails because 4 steps are requested, and only two occur prior to evaluation of text_list.
--- Note that the loss of every second "next" command can be reproduced using lldb manually with this script.

- 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.

- 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.
