Bug ID: 28253
Summary: lldb-mi Regression with LLDB_DISABLE_PYTHON=1
Product: lldb
Version: 3.8
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-...@lists.llvm.org
Reporter: pierson....@microsoft.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
When running self-built lldb-mi(3.8.1) with LLDB_DISABLE_PYTHON=1, on execution
time, I'm getting:
MI: Error: Driver. LLDB Debugger.
MI: Error: Driver Manager. Driver 'Machine Interface Driver Version: 1.0.0.9'
(ID:'MIDriver') initialise failed. Driver. LLDB Debugger.
Ilia K helped me determine that it is due to r251082 change.
The suggested workaround is:
1. ignore MI_add_summary's errors by returning TRUE:
```

uint32_t options, bool regex = false)
{
#if defined(LLDB_DISABLE_PYTHON)
- return false;
+ return true;
#else
lldb::SBTypeSummary summary = lldb::SBTypeSummary::CreateWithCallback(cb,
options);
return summary.IsValid() ?
category.AddTypeSummary(lldb::SBTypeNameSpecifier(typeName, regex), summary) :
false;
```
In this case, wide chars will not be expanded unlike simple chars:
```
(gdb) -var-create - * cp
^done,name="var7",numchild="1",value="0x0000000000400cb4
\"\\t\\\"hello\\\"\\n\"",type="const char *",thread-id="1",has_more="0"
(gdb) -var-create - * u16p
^done,name="var9",numchild="1",value="0x0000000000400d64",type="const char16_t
*",thread-id="1",has_more="0"
```
2. or you can try to revert r251082
I did #1 but would probably like wide chars to be expanded (which it does not
with the workaround).
