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.

Partly, there's just a lot of unnecessary boiler plate. It's also
possible to define combinations of arguments that make no sense (e.g.
eArgRepeatPlus followed by eArgRepeatPlain...) but these are never
checked since we just push_back directly into the argument definitions.
This commit is step 1 of this cleanup - do the obvious stuff. In it, all
the simple homogenous argument lists and the breakpoint/watchpoint
ID/Range types, are set with common functions. This is an NFC change, it
just centralizes boiler plate. There's no checking yet because you can't
get a single argument wrong.
The end goal is that all argument definition goes through functions and
m_arguments is hidden so that you can't define inconsistent argument
sets.
|
|
This is a follow-on to:
https://github.com/llvm/llvm-project/pull/82085
The completer for register names was missing from the argument table. I
somehow missed that the only register completer test was x86_64, so that
test broke.
I added the completer in to the right slot in the argument table, and
added a small completions test that just uses the alias register names.
If we end up having a platform that doesn't define register names, we'll
have to skip this test there, but it should add a sniff test for
register completion that will run most everywhere.

(#82085)"
This reverts commit 21631494b068d9364b8dc8f18e59adee9131a0a5.

Most commands were adding argument completion handling by themselves,
resulting in a lot of unnecessary boilerplate. In many cases, this could
be done generically given the argument definition and the entries in the
g_argument_table.
I'm going to address this in a couple passes. In this first pass, I
added handling of commands that have only one argument list, with one
argument type, either single or repeated, and changed all the commands
that are of this sort (and don't have other bits of business in their
completers.)
I also added some missing connections between arg types and completions
to the table, and added a RemoteFilename and RemotePath to use in places
where we were using the Remote completers. Those arguments used to say
they were "files" but they were in fact remote files.
I also added a module arg type to use where we were using the module
completer. In that case, we should call the argument module.

(not `bool`) (#69991)
[lldb] Part 2 of 2 - Refactor `CommandObject::DoExecute(...)` to return
`void` instead of ~~`bool`~~
Justifications:
- The code doesn't ultimately apply the `true`/`false` return values.
- The methods already pass around a `CommandReturnObject`, typically
with a `result` parameter.
- Each command return object already contains:
- A more precise status
- The error code(s) that apply to that status
Part 1 refactors the `CommandObject::Execute(...)` method.

This fixes #62068.
After 8d1de7b34af46a089eb5433c700419ad9b2923ee the following issue appeared:
```
$ ./bin/lldb /tmp/test.o
(lldb) target create "/tmp/test.o"
Current executable set to '/tmp/test.o' (aarch64).
(lldb) platform process launch -s
error: Cannot launch '': Nothing to launch
```
Previously would call target->GetRunArguments when there were no extra
arguments, so we could find out what target.run-args might be.
Once that change started relying on the first arg being the exe,
the fact that that call clears the existing argument list caused the bug.
Instead, have it set a local arg list and append that to the existing
one. Which in this case will just contain the exe name.
Since there's no existing tests for this command I've added a new file
that covers enough to check this issue.

This patch should allow the user to set specific auto-completion type
for their custom commands.
To do so, we had to hoist the `CompletionType` enum so the user can
access it and add a new completion type flag to the CommandScriptAdd
Command Object.
So now, the user can specify which completion type will be used with
their custom command, when they register it.
This also makes the `crashlog` custom commands use disk-file completion
type, to browse through the user file system and load the report.

This patch adds process attach capabilities to the ScriptedProcess
plugin. This doesn't really expects a PID or process name, since the
process state is already script, however, this allows to create a
scripted process without requiring to have an executuble in the target.
In order to do so, this patch also turns the scripted process related
getters and setters from the `ProcessLaunchInfo` and
`ProcessAttachInfo` classes to a `ScriptedMetadata` instance and moves
it in the `ProcessInfo` class, so it can be accessed interchangeably.
This also adds the necessary SWIG wrappers to convert the internal
`Process{Attach,Launch}InfoSP` into a `SB{Attach,Launch}Info` to pass it
as argument the scripted process python implementation and convert it
back to the internal representation.

This patch does several things:
First, it refactors the `CommandObject{,Platform}ProcessObject` command
option class into a separate `CommandOptionsProcessAttach` option group.
This will make sure both the `platform process attach` and `process attach`
command options will always stay in sync without having with duplicate
them each time. But more importantly, making this class an `OptionGroup`
allows us to combine with a `OptionGroupPythonClassWithDict` to add
support for the scripted process managing class name and user-provided
dictionary options.
This patch also improves feature parity between `ProcessLaunchInfo` and
`ProcessAttachInfo` with regard to ScriptedProcesses, by exposing the
various getters and setters necessary to use them through the SBAPI.
This is foundation work for adding support to "attach" to a process from
the scripted platform.

This patch is preparatory work for Scripted Platform support and does
multiple things:
First, it introduces new options for the `platform select` command and
`SBPlatform::Create` API, to hold a reference to the debugger object,
the name of the python script managing the Scripted Platform and a
structured data dictionary that the user can use to pass arbitrary data.
Then, it updates the various `Create` and `GetOrCreate` methods for
the `Platform` and `PlatformList` classes to pass down the new parameter
to the `Platform::CreateInstance` callbacks.
Finally, it updates every callback to reflect these changes.

This is currently being done in an ad hoc way, and so for some
commands it isn't being checked. We have the info to make this check,
since commands are supposed to add their arguments to the m_arguments
field of the CommandObject. This change uses that info to check whether
the command received arguments in error.
A handful of commands weren't defining their argument types, I also had
to fix them. And a bunch of commands were checking for arguments by
hand, so I removed those checks in favor of the CommandObject one. That
also meant I had to change some tests that were checking for the ad hoc
error outputs.

Remove File::eOpenOptionAppend from the mode used by 'platform file
open' command. According to POSIX, O_APPEND causes all successive
writes to be done at the end of the file. This effectively makes
the offset argument to 'platform file write' meaningless.
Furthermore, apparently O_APPEND is not implemented reliably everywhere.
The Linux manpage for pwrite(2) suggests that Linux does respect
O_APPEND there while according to POSIX it should not, so the actual
behavior would be dependent on how the vFile:pwrite packet is
implemented on the server.
Ideally, the mode used for opening flags would be provided via options.
However, changing the default mode seems to be a reasonable intermediate
solution.

Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB. Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits. Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write. GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.
In order to future-proof the code for the GDB variant:
1. Add a distinct eOpenOptionReadWrite constant to be used instead
of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.
2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
and eOpenOptionWriteOnly respectively, to make it clear that they
do not mean to be combined and require update to all call sites.
3. Use the intersection of all three flags when matching against
the three possible values.
This commit does not change the actual bits used by LLDB.

This replaces the current use of LLDB's own `StringConvert` with LLVM's

values' to designate parsing problems.
Where needed I also added missing error handling code that prints a parsing
error instead of continuing with the error value returned from `StringConvert`

This patch introduces the `(-h|--host)` option to the `platform shell`

Since the default behaviour of `platform shell` is to run the command of

debugging remote targets, for instances.
This patch also introduces a `shell` alias, to improve the command
discoverability and make it more convenient to use for the user.
