2025-07-10[lldb] Support specifying a language for breakpoint conditions (#147603)Jonas Devlieghere
LLDB breakpoint conditions take an expression that's evaluated using the language of the code where the breakpoint is located. Users have asked to have an option to tell it to evaluate the expression in a specific language. This is feature is especially helpful for Swift, for example for a condition based on the value in memory at an offset from a register. Such a condition is pretty difficult to write in Swift, but easy in C. This PR adds a new argument (-Y) to specify the language of the condition expression. We can't reuse the current -L option, since you might want to break on only Swift symbols, but run a C expression there as per the example above. rdar://146119507

2025-02-20[lldb] Store StreamAsynchronousIO in a unique_ptr (NFC) (#127961)Jonas Devlieghere
Make StreamAsynchronousIO an unique_ptr instead of a shared_ptr. I tried passing the class by value, but the llvm::raw_ostream forwarder stored in the Stream parent class isn't movable and I don't think it's worth changing that. Additionally, there's a few places that expect a StreamSP, which are easily created from a StreamUP.
2024-08-27[lldb] Turn lldb_private::Status into a value type. (#106163)Adrian Prantl
This patch removes all of the Set.* methods from Status. This cleanup is part of a series of patches that make it harder use the anti-pattern of keeping a long-lives Status object around and updating it while dropping any errors it contains on the floor. This patch is largely NFC, the more interesting next steps this enables is to: 1. remove Status.Clear() 2. assert that Status::operator=() never overwrites an error 3. remove Status::operator=() Note that step (2) will bring 90% of the benefits for users, and step (3) will dramatically clean up the error handling code in various places. In the end my goal is to convert all APIs that are of the form ` ResultTy DoFoo(Status& error) ` to ` llvm::Expected<ResultTy> DoFoo() ` How to read this patch? The interesting changes are in Status.h and Status.cpp, all other changes are mostly ` perl -pi -e 's/\.SetErrorString/ = Status::FromErrorString/g' $(git grep -l SetErrorString lldb/source) ` plus the occasional manual cleanup.

2023-11-09[lldb] Change interface of StructuredData::Array::GetItemAtIndexAsString ↵Alex Langford
(#71613) This patch changes the interface of StructuredData::Array::GetItemAtIndexAsString to return a `std::optional<llvm::StringRef>` instead of taking an out parameter. More generally, this commit serves as proposal that we change all of the sibling APIs (`GetItemAtIndexAs`) to do the same thing. The reason this isn't one giant patch is because it is rather unwieldy changing just one of these, so if this is approved, I will do all of the other ones as individual follow-ups.
2023-05-22[lldb] Add support for negative integer to {SB,}StructuredDataMed Ismail Bennani
This patch refactors the `StructuredData::Integer` class to make it templated, makes it private and adds 2 public specialization for both `int64_t` & `uint64_t` with a public type aliases, respectively `SignedInteger` & `UnsignedInteger`. It adds new getter for signed and unsigned interger values to the `StructuredData::Object` base class and changes the implementation of `StructuredData::Array::GetItemAtIndexAsInteger` and `StructuredData::Dictionary::GetValueForKeyAsInteger` to support signed and unsigned integers. This patch also adds 2 new `Get{Signed,Unsigned}IntegerValue` to the `SBStructuredData` class and marks `GetIntegerValue` as deprecated. Finally, this patch audits all the caller of `StructuredData::Integer` or `StructuredData::GetIntegerValue` to use the proper type as well the various tests that uses `SBStructuredData.GetIntegerValue`. rdar://105575764 Differential Revision: https://reviews.llvm.org/D150485 Signed-off-by: Med Ismail Bennani <ismail@bennani.ma>

2022-02-06[Breakpoint] Remove redundant member initialization (NFC)Kazu Hirata
Identified with readability-redundant-member-init.
2021-06-15Convert functions that were returning BreakpointOption * to BreakpointOption &.Jim Ingham
This is an NFC cleanup. Many of the API's that returned BreakpointOptions always returned valid ones. Internally the BreakpointLocations usually have null BreakpointOptions, since they use their owner's options until an option is set specifically on the location. So the original code used pointers & unique_ptr everywhere for consistency. But that made the code hard to reason about from the outside. This patch changes the code so that everywhere an API is guaranteed to return a non-null BreakpointOption, it returns it as a reference to make that clear. It also changes the Breakpoint to hold a BreakpointOption member where it previously had a UP. Since we were always filling the UP in the Breakpoint constructor, having the UP wasn't helping anything. Differential Revision: https://reviews.llvm.org/D104162
2021-03-24Make the stop-on-sharedlibrary-events setting work.Jim Ingham
The StopInfoBreakpoint::PerformAction was overriding the synchronous breakpoint's ShouldStop report. Fix that and add a test. This fixes two bugs in the original submission: 1) Actually generate both dylibs by including the second one in the Makefile 2) Don't ask synchronous callbacks for their opinion on whether to stop in the async context, that info is taken care of by recording the m_should_stop on entry to PerformAction. Differential Revision: https://reviews.llvm.org/D98914

This reverts commit 9406d43138811ac4dfd0ab31434f65a649bc882e. I messed up a test, and when I got it right it was failing. The changed logic doesn't work quite right (now the async callback called at sync time is forcing us to stop. I need to be a little more careful about that.
2021-03-19Make the stop-on-sharedlibrary-events setting work.Jim Ingham
We weren't taking into account the "m_should_stop" setting that the synchronous breakpoint callback had already set when we did PerformAction in the StopInfoBreakpoint. So we didn't obey its instructions when it told us to stop. Fixed that and added some tests both for when we just have the setting, and when we have the setting AND other breakpoints at the shared library load notification breakpoint address.

2021-02-08Reland "[lldb] Make CommandInterpreter's execution context the same as ↵Tatyana Krasnukha
debugger's one"
2020-12-17Revert "[lldb] Make CommandInterpreter's execution context the same as ↵Pavel Labath
debugger's one." This reverts commit a01b26fb51c710a3a8ef88cc83b0701461f5b9ab, because it breaks the "finish" command in some way -- the command does not terminate after it steps out, but continues running the target. The exact blast radius is not clear, but it at least affects the usage of the "finish" command in TestGuiBasicDebug.py. The error is *not* gui-related, as the same issue can be reproduced by running the same steps outside of the gui. There is some kind of a race going on, as the test fails only 20% of the time on the buildbot.
2020-12-12[lldb] Make CommandInterpreter's execution context the same as debugger's one.Tatyana Krasnukha
Currently, the interpreter's context is not updated until a command is executed. This has resulted in the behavior of SB-interface functions and some commands depends on previous user actions. The interpreter's context can stay uninitialized, point to a currently selected target, or point to one of previously selected targets. This patch removes any usages of CommandInterpreter::UpdateExecutionContext. CommandInterpreter::HandleCommand* functions still may override context temporarily, but now they always restore it before exiting. CommandInterpreter saves overriden contexts to the stack, that makes nesting commands possible. Added test reproduces one of the issues. Without this fix, the last assertion fails because interpreter's execution context is empty until running "target list", so, the value of the global property was updated instead of process's local instance.

2020-01-24[lldb][NFC] Fix all formatting errors in .cpp file headersRaphael Isemann
Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).

2019-05-08Propagate command interpreter errors from lldlbinitJonas Devlieghere
This patch ensures that we propagate errors coming from the lldbinit file trough the command/script interpreter. Before, if you did something like command script import syntax_error.py, and the python file contained a syntax error, lldb wouldn't tell you about it. This changes with the current patch: errors are now propagated by default. PS: Jim authored this change and I added testing. Differential revision: https://reviews.llvm.org/D61579 llvm-svn: 360216
2019-04-26[ScriptInterpreter] Move ownership into debugger (NFC)Jonas Devlieghere
This is part two of the change started in r359330. This patch moves the ownership of the script interpreter from the command interpreter into the debugger. I would've preferred to remove the lazy initialization, however the fact that the scripting language is set after the debugger is created makes that tricky. So for now this does exactly the same thing as when it was under the command interpreter. The result is that this patch is fully NFC.

2019-04-10[NFC] Remove ASCII lines from commentsJonas Devlieghere
A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135
2019-02-22When deserializing breakpoints some options may not be present.Jim Ingham

2019-02-13Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere
The `ap` suffix is a remnant of lldb's former use of auto pointers, before they got deprecated. Although all their uses were replaced by unique pointers, some variables still carried the suffix. In r353795 I removed another auto_ptr remnant, namely redundant calls to ::get for unique_pointers. Jim justly noted that this is a good opportunity to clean up the variable names as well. I went over all the changes to ensure my find-and-replace didn't have any undesired side-effects. I hope I didn't miss any, but if you end up at this commit doing a git blame on a weirdly named variable, please know that the change was unintentional. llvm-svn: 353912

to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

2018-02-23Fix breakpoint thread name conditionals after breakpoint options refactor.Jim Ingham
PR36435 llvm-svn: 325958
2017-09-14Make breakpoint names real entities.Jim Ingham
When introduced, breakpoint names were just tags that you could apply to breakpoints that would allow you to refer to a breakpoint when you couldn't capture the ID, or to refer to a collection of breakpoints. This change makes the names independent holders of breakpoint options that you can then apply to breakpoints when you add the name to the breakpoint. It adds the "breakpoint name configure" command to set up or reconfigure breakpoint names. There is also full support for then in the SB API, including a new SBBreakpointName class. The connection between the name and the breakpoints sharing the name remains live, so if you reconfigure the name, all the breakpoint options all change as well. This allows a quick way to share complex breakpoint behavior among a bunch of breakpoints, and a convenient way to iterate on the set. You can also create a name from a breakpoint, allowing a quick way to copy options from one breakpoint to another. I also added the ability to make hidden and delete/disable protected names. When applied to a breakpoint, you will only be able to list, delete or disable that breakpoint if you refer to it explicitly by ID. This feature will allow GUI's that need to use breakpoints for their own purposes to keep their breakpoints from getting accidentally disabled or deleted. <rdar://problem/22094452> llvm-svn: 313292
2017-08-03Add an auto-continue flag to breakpoints & locations.Jim Ingham
You can get a breakpoint to auto-continue by adding "continue" as a command, but that has the disadvantage that if you hit two breakpoints simultaneously, the continue will force the process to continue, and maybe even forstalling the commands on the other. The auto-continue flag means the breakpoints can negotiate about whether to stop. Writing tests, I wanted to supply some commands when I made the breakpoints, so I also added that ability. llvm-svn: 309969
2017-08-02Fix a mis-feature with propagation of breakpoint options -> location options.Jim Ingham
When an option was set at on a location, I was just copying the whole option set to the location, and letting it shadow the breakpoint options. That was wrong since it meant changes to unrelated options on the breakpoint would no longer take on this location. I added a mask of set options and use that for option propagation. I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands since I wanted to use them to write some more test cases. <rdar://problem/24397798> llvm-svn: 309772
2017-05-12Update StructuredData::String to return StringRefs.Zachary Turner

2017-05-12Rename Error -> Status.Zachary Turner
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

This moves the following classes from Core -> Utility. ConstString Error RegularExpression Stream StreamString The goal here is to get lldbUtility into a state where it has no dependendencies except on itself and LLVM, so it can be the starting point at which to start untangling LLDB's dependencies. These are all low level and very widely used classes, and previously lldbUtility had dependencies up to lldbCore in order to use these classes. So moving then down to lldbUtility makes sense from both the short term and long term perspective in solving this problem. Differential Revision: https://reviews.llvm.org/D29427 llvm-svn: 293941

2016-09-26Fix serialization of Python breakpoint commands.Jim Ingham

2016-09-06*** This commit represents a complete reformatting of the LLDB source codeKate Stone
*** 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
