Add a flag to Stackframe that indicates where the stack frame is the bottom-most frame of the stack. This allows clients to know whether the stack trace terminated normally or if it was truncated because the maximum depth was reached. Add a truncation message to the 'stack' command.

Fncall.go was written with the assumption that the object returned by proc.Thread.Registers does not change after we call proc.Thread.SetPC/etc. This is true for the native backend but not for gdbserial. I had anticipated this problem and introduced the Save/SavedRegisters mechanism during the first implementation of fncall.go but that's insufficient. Instead: 1. clarify that the object returned by proc.Thread.Registers could change when the CPU registers are modified. 2. add a Copy method to Registers that returns a copy of the registers that are guaranteed not to change when the CPU registers change. 3. remove the Save/SavedRegisters mechanism. This solution leaves us the option, in the future, to cache the output of proc.(Thread).Registers, avoiding a system call every time it's called.

Normally variables that have a named struct as a type will get a typedef entry as their type, sometimes however the Go linker will decide to use the DW_TAG_structure_type entry instead. For consistency always wrap a struct type into a typedef when we are creating a new variables (see comment in newVariable for exceptions). This fixes a bug where it would be impossible to call methods on a global variable.

Changes (*Variable).setValue so that it can be used in CallFunction to set up the argument frame for the function call, adding the ability to: - nil nillable types - set strings to the empty string - copy from one structure to another (including strings and slices) - convert any interface type to interface{} - convert pointer shaped types (map, chan, pointers, and structs consisting of a single pointer field) to interface{} This covers all cases where an assignment statement can be evaluated without allocating memory or calling functions in the target process.

Use the same connect code path whether we started the server (with debug/exec/test) or we didn't (i.e. the 'connect' subcommand). This fixes a bug where the init file was ignored with the 'connect' subcommand and hopefully prevents future divergence between the behavior of 'connect' and the other subcommands. Fixes #1301

If we send a process to foreground while the headless instance may get a SIGTTOU/SIGTTIN, if not ignored this signal will stop the headless. It's not clear why this only happens the second time we do this but that's how it is. Also removes the direct syscall to TIOCSPGRP and lets the go runtime do it instead. Fixes #1279

Adds a test that compares the output of our state machine with the output of the debug_line reader in the standard library and checks that they produce the same output for the debug_line section of grafana as compiled on macOS (which is the most interesting case since it uses cgo and therefore goes through dsymutil). A few bugs were uncovered and fixed: 1. is_stmt was reset improperly after a DW_LNS_end_sequence instruction 2. basic_block, prologue_end and epilogue_begin were not reset after a DW_LNS_copy instruction 3. some opcodes were not decoded properly if the debug_line section declares fewer standard opcodes than we know about. Fixes #1282

Adds -defer flag to the stack command that decorates the stack traces by associating each stack frame with its deferred calls. Reworks proc.next to use this feature instead of using proc.DeferPC, laying the groundwork to implement #1240.

next/step/stepout should work even if the current frame isn't the topmost stack frame, but their behavior should be different in that case (they should continue inside the function of the selected frame). Most of the logic of next/step/stepout would work correctly if we simply replaced the call to proc.topframe with something that took a frame index. However the breakpoint they set on the first deferred function is wrong, and fixing it requires scanning the defer stack and matching it to the call stack, something we can't do yet. Given that enhancing next/step/stepout will take time and the current behavior confuses users (see issue #1240) return an error if next/step/stepout are called while the currently selected frame isn't frame 0. Updates #1240

There is no guarantee that files will end up stored contiguously in the debug_line section which makes this optimization wrong in the general case. In particular with recent versions of go1.11 and a go.mod file present the go compiler seems to sometimes produce executables that actually violate this assumption.

The JSON-RPC layer doesn't like non-nil error that return an empty string when the Error method is called and when this happens it shuts down the connection to the server. Since we can return a ThreadBlockedError to the client it can't have an empty string as return value. Fixes #1251

Setting the Level field of a logrus logger doesn't actually do anything since the Level field simply reports the log level of the last log message emitted on the logger. The right way to do that is to set logger.Logger.Level. Also cleans up newline characters from log messages emitted through logrus and fixes the direction of the arrows in the messages emitted by rpccommon, which was inconsistent with the arrows of gdbserial.

This pull request makes several changes to delve to allow headless instancess that are started with the --accept-multiclient flag to keep running even if there is no connected client. Specifically: 1. Makes a headless instance started with --accept-multiclient quit after one of the clients sends a Detach request (previously they would never ever quit, which was a bug). 2. Changes proc/gdbserial and proc/native so that they mark the Process as exited after they detach, even if they did not kill the process during detach. This prevents bugs such as #1231 where we attempt to manipulate a target process after we detached from it. 3. On non --accept-multiclient instances do not kill the target process unless we started it or the client specifically requests it (previously if the client did not Detach before closing the connection we would kill the target process unconditionally) 4. Add a -c option to the quit command that detaches from the headless server after restarting the target. 5. Change terminal so that, when attached to --accept-multiclient, pressing ^C will prompt the user to either disconnect from the server or pause the target process. Also extend the exit prompt to ask if the user wants to keep the headless server running. Implements #245, #952, #1159, #1231
