This patch moves the `history` subcommand from the `command` to `session` command. I think it makes more sense to have it there because as the `command` usage suggests, it should be used to manage custom LLDB commands. However, `history` is essentially tied to a debugging session and holds all the commands (not specifically custom ones). This also makes it more discoverable by adding an alias for it (mimicking the shell builtin).

This is how it should've been and brings it more in line with std::string_view. There should be no functional change here. This is mostly mechanical from a custom clang-tidy check, with a lot of manual fixups. It uncovers a lot of minor inefficiencies.

2020-01-24[lldb][NFC] Fix all formatting errors in .cpp file headersRaphael Isemann1-1/+1
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).

2019-09-27remove File::SetStream(), make new files instead.Lawrence D'Anna1-3/+3
Summary: This patch removes File::SetStream() and File::SetDescriptor(), and replaces most direct uses of File with pointers to File. Instead of calling SetStream() on a file, we make a new file and replace it. My ultimate goal here is to introduce a new API class SBFile, which has full support for python io.IOStream file objects. These can redirect read() and write() to python code, so lldb::Files will need a way to dispatch those methods. Additionally it will need some form of sharing and assigning files, as a SBFile will be passed in and assigned to the main IO streams of the debugger. In my prototype patch queue, I make File itself copyable and add a secondary class FileOps to manage the sharing and dispatch. In that case SBFile was a unique_ptr<File>. (here: https://github.com/smoofra/llvm-project/tree/files) However in review, Pavel Labath suggested that it be shared_ptr instead. (here: https://reviews.llvm.org/D67793) In order for SBFile to use shared_ptr<File>, everything else should as well. If this patch is accepted, I will make SBFile use a shared_ptr I will remove FileOps from future patches and use subclasses of File instead.

Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases).

2019-08-22[lldb][NFC] Remove WordComplete mode, make result array indexed from 0 and ↵Raphael Isemann1-8/+6
remove any undocumented/redundant return values Summary: We still have some leftovers of the old completion API in the internals of LLDB that haven't been replaced by the new CompletionRequest. These leftovers are: * The return values (int/size_t) in all completion functions. * Our result array that starts indexing at 1. * `WordComplete` mode. I didn't replace them back then because it's tricky to figure out what exactly they are used for and the completion code is relatively untested. I finally got around to writing more tests for the API and understanding the semantics, so I think it's a good time to get rid of them. A few words why those things should be removed/replaced: * The return values are really cryptic, partly redundant and rarely documented. They are also completely ignored by Xcode, so whatever information they contain will end up breaking Xcode's completion mechanism. They are also partly impossible to even implement as we assign negative values special meaning and our completion API sometimes returns size_t. Completion functions are supposed to return -2 to rewrite the current line. We seem to use this in some untested code path to expand the history repeat character to the full command, but I haven't figured out why that doesn't work at the moment. Completion functions return -1 to 'insert the completion character', but that isn't implemented (even though we seem to activate this feature in LLDB sometimes). All positive values have to match the number of results. This is obviously just redundant information as the user can just look at the result list to get that information (which is what Xcode does). * The result array that starts indexing at 1 is obviously unexpected. The first element of the array is reserved for the common prefix of all completions (e.g. "foobar" and "footar" -> "foo"). The idea is that we calculate this to make the life of the API caller easier, but obviously forcing people to have 1-based indices is not helpful (or even worse, forces them to manually copy the results to make it 0-based like Xcode has to do). * The `WordComplete` mode indicates that LLDB should enter a space behind the completion. The idea is that we let the top-level API know that we just provided a full completion. Interestingly we `WordComplete` is just a single bool that somehow represents all N completions. And we always provide full completions in LLDB, so in theory it should always be true. The only use it currently serves is providing redundant information about whether we have a single definitive completion or not (which we already know from the number of results we get). This patch essentially removes `WordComplete` mode and makes the result array indexed from 0. It also removes all return values from all internal completion functions. The only non-redundant information they contain is about rewriting the current line (which is broken), so that functionality was moved to the CompletionRequest API. So you can now do `addCompletion("blub", "description", CompletionMode::RewriteLine)` to do the same. For the SB API we emulate the old behaviour by making the array indexed from 1 again with the common prefix at index 0. I didn't keep the special negative return codes as we either never sent them before (e.g. -2) or we didn't even implement them in the Editline handler (e.g. -1). I tried to keep this patch minimal and I'm aware we can probably now even further simplify a bunch of related code, but I would prefer doing this in follow-up NFC commits Reviewers: JDevlieghere Reviewed By: JDevlieghere Subscribers: arphaman, abidh, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D66536 llvm-svn: 369624

2019-04-10[NFC] Remove ASCII lines from commentsJonas Devlieghere1-26/+0
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
2019-03-10Quiet command regex instructions during batch executionDave Lee1-5/+5
Summary: Within .lldbinit, regex commands can be structured as a list of substitutions over multiple lines. It's possible that this is uninentional, but it works and has benefits. For example: command regex <command-name> s/pat1/repl1/ s/pat2/repl2/ ... I use this form of `command regex` in my `~/.lldbinit`, because it makes it clearer to write and read compared to a single line definition, because multiline substitutions don't need to be quoted, and are broken up one per line. However, multiline definitions result in usage instructions being printed for each use. The result is that every time I run `lldb`, I get a dozen or more lines of noise. With this change, the instructions are only printed when `command regex` is invoked interactively, or from a terminal, neither of which are true when lldb is sourcing `~/.lldbinit`.

2019-03-02[Reproducers] Capture and replay interpreter commands.Jonas Devlieghere1-1/+1
This patch adds the necessary logic to capture and replay commands entered into the command interpreter. A DataRecorder shadows the input and writes its data to a know file. During replay this file is used as the command interpreter's input. It's possible to the command interpreter more than once, with a different input source. We support this scenario by using multiple buffers. The synchronization for this takes place at the SB layer, where we create a new recorder every time the debugger input is changed. During replay we use the corresponding buffer as input. Differential revision: https://reviews.llvm.org/D58564 llvm-svn: 355249

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.

Summary: Add settings to control command echoing: ``` (lldb) settings set interpreter.echo-commands true (lldb) settings set interpreter.echo-comment-commands true ``` Both settings default to true, which keeps LLDB's existing behavior in non-interactive mode (echo all command inputs to the output). So far the only way to change this behavior was the `--source-quietly` flag, which disables all output including evaluation results. Now `echo-commands` allows to turn off echoing for commands, while evaluation results are still printed. No effect if `--source-quietly` was present. `echo-comment-commands` allows to turn off echoing for commands in case they are pure comment lines. No effect if `echo-commands` is false. Note that the behavior does not change immediately! The new settings take effect only with the next command source. LLDB lit test are the main motivation for this feature. So far incoming `#CHECK` line have always been echoed to the output and so they could never fail. Now we can disable it in lit-lldb-init. Todos: Finish test for this feature. Add to lit-lldb-init.

2018-07-27Narrow the CompletionRequest API to being append-only.Raphael Isemann1-2/+2
Summary: We currently allow any completion handler to read and manipulate the list of matches we calculated so far. This leads to a few problems: Firstly, a completion handler's logic can now depend on previously calculated results by another handlers. No completion handler should have such an implicit dependency, but the current API makes it likely that this could happen (or already happens). Especially the fact that some completion handler deleted all previously calculated results can mess things up right now. Secondly, all completion handlers have knowledge about our internal data structures with this API. This makes refactoring this internal data structure much harder than it should be. Especially planned changes like the support of descriptions for completions are currently giant patches because we have to refactor every single completion handler. This patch narrows the contract the CompletionRequest has with the different handlers to: 1. A handler can suggest a completion. 2. A handler can ask how many suggestions we already have. Point 2 obviously means we still have a dependency left between the different handlers, but getting rid of this is too large to just append it to this patch. Otherwise this patch just completely hides the internal StringList to the different handlers. The CompletionRequest API now also ensures that the list of completions is unique and we don't suggest the same value multiple times to the user. This property has been so far only been ensured by the `Option` handler, but is now applied globally. This is part of this patch as the OptionHandler is no longer able to implement this functionality itself.

Summary: As suggested in D48796, this patch replaces even more internal calls that were using the old completion API style with a single CompletionRequest. In some cases we also pass an option vector/index, but as we don't always have this information, it currently is not part of the CompletionRequest class. The constructor of the CompletionRequest is now also more sensible. You only pass the user input, cursor position and your list of matches to the request and the rest will be inferred (using the same code we used before to calculate this). You also have to pass these match window parameters to it, even though they are unused right now. The patch shouldn't change any behavior.

There seems to be a assumption in some command objects that this parameter could be a nullptr, but from what I can see the rest of the API doesn't actually allow this (and other command objects and related code pieces dereference this parameter without any checks).

2018-07-02Refactoring for for the internal command line completion API (NFC)Raphael Isemann1-22/+23
Summary: This patch refactors the internal completion API. It now takes (as far as possible) a single CompletionRequest object instead o half a dozen in/out/in-out parameters. The CompletionRequest contains a common superset of the different parameters as far as it makes sense. This includes the raw command line string and raw cursor position, which should make the `expr` command possible to implement (at least without hacks that reconstruct the command line from the args). This patch is not intended to change the observable behavior of lldb in any way. It's also as minimal as possible and doesn't attempt to fix all the problems the API has. Some Q&A: Q: Why is this not fixing all the problems in the completion API? A: Because is a blocker for the expr command completion which I want to get in ASAP. This is the smallest patch that unblocks the expr completion patch and which allows trivial refactoring in the future. The patch also doesn't really change the internal information flow in the API, so that hopefully saves us from ever having to revert and resubmit this humongous patch. Q: Can we merge all the copy-pasted code in the completion methods (like computing the current incomplete arg) into CompletionRequest class? A: Yes, but it's out of scope for this patch. Q: Why the `word_complete = request.GetWordComplete(); ... ` pattern? A: I don't want to add a getter that returns a reference to the internal integer. So we have to use a temporary variable and the Getter/Setter instead. We don't throw exceptions from what I can tell, so the behavior doesn't change. Q: Why are we not owning the list of matches? A: Because that's how the previous API works. But that should be fixed too (in another patch). Q: Can we make the constructor simpler and compute some of the values from the plain command? A: I think this works, but I rather want to have this in a follow up commit. Especially when making nested request it's a bit awkward that the parsed arguments behave as both input/output (as we should in theory propagate the changes on the nested request back to the parent request if we don't want to change the behavior too much). Q: Can't we pass one const request object and then just return another result object instead of mixing them together in one in/out parameter? A: It's hard to get keep the same behavior with that pattern, but I think we can also get a nice API with just a single request object. If we make all input parameters read-only, we have a clear separation between what is actually an input and what an output parameter (and hopefully we get rid of the in-out parameters). Q: Can we throw out the 'match' variables that are not implemented according to the comment? A: We currently just forward them as in the old code to the different methods, even though I think they are really not used. We can easily remove and readd them once every single completion method just takes a CompletionRequest, but for now I prefer NFC behavior from the perspective of the API user.

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
2018-04-17Move Args.cpp from Interpreter to UtilityPavel Labath1-1/+1
Summary: The Args class is used in plenty of places besides the command interpreter (e.g., anything requiring an argc+argv combo, such as when launching a process), so it needs to be in a lower layer. Now that the class has no external dependencies, it can be moved down to the Utility module. This removes the last (direct) dependency from the Host module to Interpreter, so I remove the Interpreter module from Host's dependency list.

2018-04-10Move Args::StringTo*** functions to a new OptionArgParser classPavel Labath1-1/+2
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.

2017-05-12Rename Error -> Status.Zachary Turner1-27/+27
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
