Greg Clayton 57ee306789 Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

Enrico Granata c2a96407c5 Remove the #define USE_CACHE since the formatters cache has been operational for a while now and has not caused issues that warrant disabling it
Also, print the cache hits statistics if the log is in debugging mode vs. LLDB being a debug build - this should make it easier to gather useful metrics on cache success rate for real users

2013-04-19 21:31:16 +00:00
Ashok Thirumurthi 6ac9d13e61 Provided a variant of ReadCStringFromMemory that supports null terminators of any character width.
This prevents unbounded reads (i.e. reads of GetMaximumSizeOfStringSummary() bytes)
from causing test failures (i.e. due to ptrace EIO or EFAULT on Linux).

Note that ReadCStringFromMemory is marked as deprecated because the loop that calls
ReadMemory does not continue until the string has been completely read.
The expected behavior is to read until until max_bytes or a null terminator.

Note: As discussed on lldb-dev, further testing will be performed with ReadStringFromMemory
before further changes are made for users of ReadCStringFromMemory.

Thanks to Enrico, Matt and Andy for their review feedback.

Enrico Granata f15ee4e89f <rdar://problem/13563628>
Introducing a negative cache for ObjCLanguageRuntime::LookupInCompleteClassCache()
This helps speed up the (common) case of us looking for classes that are hidden deep within Cocoa internals and repeatedly failing at finding type information for them.
In order for this to work, we need to clean this cache whenever debug information is added. A new symbols loaded event is added that is triggered with add-dsym (before modules loaded would be triggered for both adding modules and adding symbols).
Interested parties can register for this event. Internally, we make sure to clean the negative cache whenever symbols are added.
Lastly, ClassDescriptor::IsTagged() has been refactored to GetTaggedPointerInfo() that also (optionally) returns info and value bits. In this way, data formatters can share tagged pointer code instead of duplicating the required arithmetic.

Reimplemented the NSDictionary synthetic children provider for added performance.

Fixing a bug where LLDB was not handling correctly CFStrings that have an explicit length but no NULL terminator

Greg Clayton 5160ce5c72 <rdar://problem/13521159>
LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Data formatters now cache themselves.
This commit provides a new formatter cache mechanism. Upon resolving a formatter (summary or synthetic), LLDB remembers the resolution for later faster retrieval.
Also moved the data formatters subsystem from the core to its own group and folder for easier management, and done some code reorganization.
The ObjC runtime v1 now returns a class name if asked for the dynamic type of an object. This is required for formatters caching to work with the v1 runtime.
Lastly, this commit disposes of the old hack where ValueObjects had to remember whether they were queried for formatters with their static or dynamic type.
Now the ValueObjectDynamicValue class works well enough that we can use its dynamic value setting for the same purpose.
