Move Args::StringTo*** functions to a new OptionArgParser class Summary: The idea behind this is to move the functionality which depend on other lldb classes into a separate class. This way, the Args class can be turned into a lightweight arc+argv wrapper and moved into the lower lldb layers.

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860

This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output.

Re-land r313210 - Fix for bug 34532 - A few rough corners related to post-mortem debugging (core/minidump) The main change is to avoid setting the process state as running when debugging core/minidumps (details in the bug). Also included a few small, related fixes around how the errors propagate in this case. Fixed the FreeBSD/Windows break: the intention was to keep Process::WillResume() and Process::DoResume() "in-sync", but this had the unfortunate consequence of breaking Process sub-classes which don't override WillResume(). The safer approach is to keep Process::WillResume() untouched and only override it in the minidump and core implementations. patch by lemo Bug: https://bugs.llvm.org/show_bug.cgi?id=34532 Differential Revision: https://reviews.llvm.org/D37651 llvm-svn: 313655

Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output.

The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output. I needed this behavior recently when debugging a core with 700+ threads.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class.

Introduce new command: thread backtrace unique This patch introduces a new thread backtrace command "unique". The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output.

Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

Thread *thread = thread_sp.get();
Centralized a lot of the status information for processes, threads, and stack frame down in the lldb_private::Process, lldb_private::Thread, lldb_private::StackFrameList and the lldb_private::StackFrame classes. We had some command line commands that had duplicate versions of the process status output ("thread list" and "process status" for example). Removed the "file" command and placed it where it should have been: "target create". Made an alias for "file" to "target create" so we stay compatible with GDB commands. We can now have multple usable targets in lldb at the same time. This is nice for comparing two runs of a program or debugging more than one binary at the same time. The new command is "target select <target-idx>" and also to see a list of the current targets you can use the new "target list" command. The flow in a debug session can be: (lldb) target create /path/to/exe/a.out (lldb) breakpoint set --name main (lldb) run ... hit breakpoint (lldb) target create /bin/ls (lldb) run /tmp Process 36001 exited with status = 0 (0x00000000) (lldb) target list Current targets: target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped ) * target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited ) (lldb) target select 0 Current targets: * target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped ) target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited ) (lldb) bt * thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1 frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16 frame #1: 0x0000000100000b64 a.out`start + 52 Above we created a target for "a.out" and ran and hit a breakpoint at "main". Then we created a new target for /bin/ls and ran it. Then we listed the targest and selected our original "a.out" program, so we showed two concurent debug sessions going on at the same time. llvm-svn: 129695

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Introduce new command: thread backtrace unique This patch introduces a new thread backtrace command "unique". The command is based off of "thread backtrace all" but will instead find all threads which share matching call stacks and de-duplicate their output, listing call stack and all the threads which share it. This is especially useful for apps which use thread/task pools sitting around waiting for work and cause excessive duplicate output. I needed this behavior recently when debugging a core with 700+ threads.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

This change introduces a "ExpressionExecutionThread" to the ThreadList. Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on behalf of the expression parser was using the currently selected thread. But sometimes, e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread we're running on, we instead set the context for the interpreter, and explicitly pass that to other callers. That wasn't getting communicated to these utility expressions, so they would run on some other thread instead, and that could cause a variety of subtle and hard to reproduce problems. I also went through the commands and cleaned up the use of GetSelectedThread. All those uses should have been trying the thread in the m_exe_ctx belonging to the command object first. It would actually have been pretty hard to get misbehavior in these cases, but for correctness sake it is good to make this usage consistent. <rdar://problem/24978569> llvm-svn: 263326

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

This is an idea to make "thread step-in --target" work for the common case where you have: 1 -> foo (bar(), 2 baz(), 3 lala()); 4 You are sitting on line 1, and want to step into foo, but not bar, baz & lala. Unfortunately there are line table entries for lines 1-3, and lldb doesn't know anything about the nesting of statement in these lines. So we'll have to use the user's intelligence... This patch adds: (lldb) thread step-in -t foo --end-line 4 That tells lldb to keep stepping in till line 4, but stop if you step into foo. I think I would remember to use this when faced with some of the long gnarly call sequences in lldb. But there might be ways I haven't thought of to make it more convenient. Jason suggests having "end" as a special token for --end-line which just means keep going to the end of the function, I really want to get into this thing... There should be an SB API and tests, which will come if this seems useful. llvm-svn: 260352

The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set.

Make the "synchronous" mode actually work without race conditions. There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Re-land r313210 - Fix for bug 34532 - A few rough corners related to post-mortem debugging (core/minidump) The main change is to avoid setting the process state as running when debugging core/minidumps (details in the bug). Also included a few small, related fixes around how the errors propagate in this case. Fixed the FreeBSD/Windows break: the intention was to keep Process::WillResume() and Process::DoResume() "in-sync", but this had the unfortunate consequence of breaking Process sub-classes which don't override WillResume(). The safer approach is to keep Process::WillResume() untouched and only override it in the minidump and core implementations. patch by lemo Bug: https://bugs.llvm.org/show_bug.cgi?id=34532 Differential Revision: https://reviews.llvm.org/D37651 llvm-svn: 313655

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Reflow paragraphs in comments. This is intended as a clean up after the big clang-format commit (r280751), which unfortunately resulted in many of the comment paragraphs in LLDB being very hard to read. FYI, the script I used was: import textwrap import commands import os import sys import re tmp = "%s.tmp"%sys.argv[1] out = open(tmp, "w+") with open(sys.argv[1], "r") as f: header = "" text = "" comment = re.compile(r'^( *//) ([^ ].*)$') special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$') for line in f: match = comment.match(line) if match and not special.match(match.group(2)): # skip intentionally short comments. if not text and len(match.group(2)) < 40: out.write(line) continue if text: text += " " + match.group(2) else: header = match.group(1) text = match.group(2) continue if text: filled = textwrap.wrap(text, width=(78-len(header)), break_long_words=False) for l in filled: out.write(header+" "+l+'\n') text = "" out.write(line) os.rename(tmp, sys.argv[1]) Differential Revision: https://reviews.llvm.org/D46144 llvm-svn: 331197

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Don't allow direct access to StreamString's internal buffer. This is a large API change that removes the two functions from StreamString that return a std::string& and a const std::string&, and instead provide one function which returns a StringRef. Direct access to the underlying buffer violates the concept of a "stream" which is intended to provide forward only access, and makes porting to llvm::raw_ostream more difficult in the future.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Very large changes that were needed in order to allow multiple connections to the debugger from GUI windows.

Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235

Clean up the stop printing header lines. I added a "thread-stop-format" to distinguish between the form that is just the thread info (since the stop printing immediately prints the frame info) and one with more frame 0 info - which is useful for "thread list" and the like. I also added a frame.no-debug boolean to the format entities so you can print frame information differently between frames with source info and those without.

2010-06-09 00:52:24 +08:00
Initial merge of some of the iOS 8 / Mac OS X Yosemite specific lldb support. I'll be doing more testing & cleanup but I wanted to get the initial checkin done. This adds a new SBExpressionOptions::SetLanguage API for selecting a language of an expression. I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around.

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Thread *thread = thread_sp.get();
Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

I added adds a new SBThread::GetInfoItemByPathString for retriving information about a thread from that thread's StructuredData. I added a new StructuredData class for representing key-value/array/dictionary information (e.g. JSON formatted data). Helper functions to read JSON and create a StructuredData object, and to print a StructuredData object in JSON format are included. A few Cocoa / Cocoa Touch data formatters were updated by Enrico to track changes in iOS 8 / Yosemite. Before we query a thread's extended information, the system runtime may provide hints to the remote debug stub that it will use to retrieve values out of runtime structures. I added a new SystemRuntime method AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add key-value type data to the initial request that we send to the remote stub. The thread-format formatter string can now retrieve values out of a thread's extended info structured data. The default thread-format string picks up two of these - thread.info.activity.name and thread.info.trace_messages. I added a new "jThreadExtendedInfo" packet in debugserver; I will add documentation to the lldb-gdb-remote.txt doc soon. It accepts JSON formatted arguments (most importantly, "thread":threadnum) and it returns a variety of information regarding the thread to lldb in JSON format. This JSON return is scanned into a StructuredData object that is associated with the thread; UI layers can query the thread's StructuredData to see if key-values are present, and if so, show them to the user. These key-values are likely to be specific to different targets with some commonality among many targets. For instance, many targets will be able to advertise the pthread_t value for a thread. I added an initial rough cut of "thread info" command which will print the information about a thread from the jThreadExtendedInfo result. I need to do more work to make this format reasonably. Han Ming added calls into the pmenergy and pmsample libraries if debugserver is run on Mac OS X Yosemite to get information about the inferior's power use. I added support to debugserver for gathering the Genealogy information about threads, if it exists, and returning it in the jThreadExtendedInfo JSON result. llvm-svn: 210874

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface.

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642

Fix deadlock due to thread list locking in 'bt all' with obj-c Summary: The gdb-remote async thread cannot modify thread state while the main thread holds a lock on the state. Don't use locking thread iteration for bt all. Specifically, the deadlock manifests when lldb attempts to JIT code to symbolicate objective c while backtracing. As part of this code path, SetPrivateState() is called on an async thread. This async thread will block waiting for the thread_list lock held by the main thread in CommandObjectIterateOverThreads. The main thread will also block on the async thread during DoResume (although with a timeout), leading to a deadlock. Due to the timeout, the deadlock is not immediately apparent, but the inferior will be left in an invalid state after the bt all completes, and objective-c symbols will not be successfully resolved in the backtrace.

*** This commit represents a complete reformatting of the LLDB source code *** 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

This checkin is the first step in making the lldb thread stepping mechanism more accessible from the user level. It adds the ability to invent new stepping modes implemented by python classes, and to view the current thread plan stack and to some extent alter it. I haven't gotten to documentation or tests yet. But this should not cause any behavior changes if you don't use it, so its safe to check it in now and work on it incrementally. llvm-svn: 218642
