[lldb] Turn lldb_private::Status into a value type. (#106163) 2024-08-27T17:59:31+00:00 Adrian Prantl aprantl@apple.com 2024-08-27T17:59:31+00:00 0642cd768b80665585c8500bed2933a3b99123dc 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. 
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.
 [lldb] [Process/FreeBSDKernel] Support finding all processes 2022-01-06T20:53:28+00:00 Michał Górny mgorny@moritz.systems 2021-12-22T07:45:16+00:00 9b1d27b2fa727a3a6f53a803d75beed50a1be999 Include the complete list of threads of all running processes in the FreeBSDKernel plugin. This makes it possible to inspect the states (including partial register dumps from PCB) of all kernel and userspace threads at the time of crash, or at the time of reading /dev/mem first.
