BTW, Re. source file fetching .... pkg/terminal/command.go printfile() could be the right place to call out to debuginfod-find source BUILDID /foo/bar.go, if it has available to it the buildid of the target thread's current executable.

    dap: support 'Env' attribute for launch requests (#2846)

    * dap: support 'Env' attribute for launch requests

    Env is applied in addition to the delve process environment
    variables. The env setting is done by calling os.Setenv
    as early as possible when a Launch request is received.

    Prior discussion is in

    In Visual Studio Code, setting null for an environment variable
    in launch.json or tasks.json indicates users want to unset
    the environment variable. Support the behavior by accepting
    nil value.

    pkg/terminal: Support `b` and `t` without a linespec (#2863)

    This could probably be more user-friendly, in that you can't give a name
    to such a breakpoint.  To add support for names, we would need to try
    a single arg first as a location, and if that fails try it as a name for
    current line.  That seems somewht dubious, so I didn't try.

    proc/gdbserial: allow rewind to work after process exit with rr (#2815)

    * service/debugger: fix bug internal err with Restart on recorded target

    If Restart is called after a Continue and Rewind on a recorded target
    that has already terminated it will return an internal error.

    * proc/gdbserial: allow rewind to work after process exit with rr

    It is sometimes useful to set breakpoints and rewind a terminated
    process when using rr, for example if interested in the last execution
    of some function.
    RR will not allow a backward continue after the process exit packet has
    been  sent, however rr will also generate a synthetic SIGKILL right
    before process exit.
    Treat this packet as a process exit and change some things so both
    continuing backwards and setting breakpoints can be done, on recorded
    targets, after process exit has been reported.

    proc: fix signal handling during stepping (#2803)

    Fix signal handling during thread single stepping so that signals that
    are generated by executing the current instruction are immediately
    propagated to the inferior, while signals other signals sent to the
    thread are delayed until the full resume happens.

    Fixes a bug where a breakpoint set on an instruction that causes a
    SIGSEGV would make Delve hang and a bug where signals received during
    single step would make it look like an instruction is executed twice.

    Fixes #2801

    service/dap: add config expressions to evaluate requests (#2750)

    We want to provide more flexibility for users to make changes to their configurations while the debug session is running. This could be accomplished by creating a custom request, but that were require a new UI as well, and every client of dlv dap to provide its own UI for this. By using the evaluate context, users can use the already existing debug console to change their configurations.

    This change includes a refactor of the terminal code in order to share the code with the dap package.

    This change provides a very similar to UI as the terminal package, but there are different configuration options that are DAP specific. We plan to use this same mechanism to expose a few other commands including "sources" to help users debug an ineffective substitutePath configuration.

    service/dap: improve shutdown logic and test coverage (#2749)

    This high-level goal is to push more shutdown logic into Session and not rely Server.Stop() because dap's version of Stop() is different from rpccommon. That means triggering the same shutdown steps in multiple places, so additional safeguards are added to make some of the duplicate steps no-ops to avoid errors, extra logging, etc.

    This includes the following changes:

    close client conn when request loop in serveDAPCodec exits (to match rpccommon)
    exit request loop after processing a disconnect request (instead of relying on next read to fail because conn got closed by triggered Stop(), which is skipped in case of accept-multiclient and is not closed in Stop() in rpccommon)
    reset debugger to nil to avoid shutting it down more than once and causing duplicate logging (in case stopDebugSession is called from onDisconnectRequest and Server.Stop or Session.Close as things shut down)
    reset binaryToRemove to "" upon removal to avoid duplicate error (in case Close() is called more than once outside of Stop(), which technically is not the case right now)
    expand testing for all possible server shutdown triggers
    testing for Session-only shutdown as it will be integrated into rpccommon without dap.Server wrapper

    output with spaces to right justify the frame number, which confuses

    * _scripts: pass -buildvcs for Go 1.18 and later on TeamCity

    Go 1.18 will try to stamp builds with the VCS version, this doesn't
    work on TeamCity because the checkout isn't a valid repository (but
    looks like it).
    Pass -buildvcs=false to disable this feature.

    * proc: switch to goroutine stack if first frame's func can not be found

    If the first frame on the system stack can not be resolved to a
    function switch directly to the goroutine stack.

    proc/gdbserial: support call injection with rr backend (#2740)

    Normally calls can't be performed on recorded processes, becuase the
    future instructions executed by the target are predetermined. The rr
    debugger however has a mechanism that allows this by taking the current
    state of the recording and allowing it to diverge from the recording,
    This commit adds support for starting and ending such diversions around
    function calls.

    Note: this requires rr version 5.5 of later to work, see:

    cmd/dlv: add --client-addr flag to run dap with a predefined client (#2568)

    This adds a new `--client-addr=host:port` flag to `dlv dap`.
    If it is supplied, the dap process will dial into the tcp port where
    a DAP client is waiting, and work with only the DAP client.
    The DAP client is supposed to start the normal DAP message
    exchange starting with the 'initialize' request after the dlv dap
    process dials in and the connection is set up.

    VS Code Go extension plans to use this mode for

    * reliably detecting `dlv dap` readiness. Currently it depends on
    watching the log stream. After this PR, it can listen on a network port.
    * running `dlv dap` from any terminal (part of RunInTerminal workflow

    On Windows RequestManualStop will generate an exception on a special
    DbgUiRemoteBreakin thread, sometimes this thread will die before we
    finish stopping the process. We need to account for that and still stop
    even if the thread is gone and no other thread hit a breakpoint.

    Fixes flakiness of TestIssue419.

    When a new thread is created we must reapply all watchpoints to it,

    We can not guarantee that we find all goroutines stopped in a good
    place and sometimes the stacktrace fails on Windows.

    proc: do not assign temporary breakpoint IDs (#2650)

    Internal breakpoints do not need IDs and assigning them from a counter
    separate from the user ID counter can be a cause of confusion.
    If a user breakpoint is overlayed on top of a pre-existing internal
    breakpoint the temporary ID will be surfaced as if it was a user ID,
    possibly conflicting with another user ID.
    If a temporary breakpoint is overlayed on top of a pre-existing user
    breakpoint and the user breakpoint is first deleted and then
    re-created, the user ID will be resurrected along with the breakpoint,
    instead of allocating a fresh one.

    This change removes internal breakpoint IDs entirely, only user
    breakpoints receive an ID.

    pkg/proc: merge register data before writing to register (#2699)

    Right now, if (*compositeMemory).WriteMemory needs to write a value to
    a register that's smaller than the full size of the register (say, a
    uint32 being passed as an argument), then (*AMD64Registers).SetReg can
    later fail a sanity check that ensures the passed DwarfRegister is a
    full size register.

    Fix this by reading the old value of the register and overwriting just
    the relevant parts with the new register. For the purposes of an
    argument, it would probably be fine to just pad with zeroes, but merging
    with the existing value is what gdb does.

    service/dap: add basic log points (#2634)

    Log points are special kinds of breakpoints that do not 'break' but instead log a message and then continue. This change implements basic log points that simply log the provided message, without any interpolation.

    In order to resume execution after hitting a breakpoint, I added a new lock resumeMu and tracked the running state within the DAP server. resumeMu must be held in order to issue a debugger request that would start execution. This means it can be used to make sure that another goroutine does not resume execution while you are holding the lock.

    Most of the synchronization logic is taken from PR #2530

    pkg/proc: update check for system goroutine (#2585)

    * pkg/proc: update check for system goroutine

    The finalizer goroutine can be either a system goroutine or a user goroutine. It is considered a user goroutine only when it calls back to user code. This change attempts to get closer to the implementation in the src/runtime/traceback.go by checking the value of fingRunning.

    We could alternatively adopt the approximation done by src/cmd/trace/trace.go which only special cases "runtime.main", and always considers the finalizer to be a system goroutine.

    Prefer string variant for source-list-line-color config option (#2676)

    The string variant is more powerful and can be passed
    directly to "echo -e" / "printf" and friends.

    Remove the mention of the integer variant from the default config. This
    makes the option appear more consistent with other color options.
    The user shouldn't care about the historic differences.

    terminal: config -list to print strings inside interfaces in quotes (#2680)

    Commit 3d6bbbe9 made "config -list" print strings in quotes to avoid
    the strings being interpreted as terminal escape codes.  This commit
    does the same for "source-list-line-color", which is a raw interface.
    This fixes "config -list" with a config like

    	source-list-line-color: "\x1b[34m"

    The "int" variant is already printed correctly, so just use the
    default case for that.

    service/dap: include selected goroutine in threads request (#2683)

    When we set a limit on the number of threads that would be
    returned, it was possible that the selected thread was not
    included in the list of threads. This could cause issues
    because the stopped reason is associated with the selected
    goroutine, so users could be missing out on important info.

    This change makes sure that the selected goroutine is included
    by adding it to the end of the list.

    dap: define LaunchConfig/AttachConfig types (#2571)

    Formally define these types and document their meaning.
    We will auto-generate the dlv-dap documentation from these Go type doc.

    mapToStruct is a helper that sets the given struct's fields with the
    info in map[string]interface{} (launch/attach's Arguments). We achieve
    this by reencoding map[string]interface{} to json and decoding back to
    the target struct. If go-dap left the implementation-specific arguments
    as json.RawMessage and let the implementation decode as needed, this
    reencoding could've been avoided.

    encoding/json itself does not have mean to enforce required fields.
    There was a test case that checks substitutePath elements must set
    both from/to fields. Path.UnmarshalJSON implements the check.
    I am not yet sure about the need for distinction between missing
    'from/to' and empty strings yet. (empty value is useful when dealing with
    a binary built with trimpath, right?)

    A minor behavior change - previously, if noDebug is not a boolean type,
    we ignored the attribute silently. Since we use json decoding, any
    mismatched types will cause an error and this non-boolean type noDebug
    attribute will result in launch failure.

    service: fix sameuser check (#2642)

    Change the socket search to check both the remote and local fields of the
    socket match the socket we want to find.

    Sockets are identified by the 4-uple

    	local_addr, local_port, remote_addr, remote_port

    Two socket can differ by a single one of this four elements.
    It is possible for the same local_port to be used by two different sockets,
    as long as they are connecting to different remote addresses (or remote

    An example of this bug in action can be seen at:

    There the server starts listening on and rejects a valid
    client connection by finding the following socket:

    60: 0100007F:DD82 0100007F:962D 06 00000000:00000000 03:00000133 00000000     0        0 0 3 0000000000000000

    the local address of this socket is 0100007F:DD82 (, and the
    remote address is 0100007F:962D (

    The reported error is:

    	closing connection from different user ( connections to localhost are only accepted from the same UNIX user for security reasons

    note how the local port does match the socket line (56706) but the remote
    port is wrong (38445 instead of 46011).

    Note also that the state of this socket is 06, or TIME_WAIT, which would be
    impossible if this was the right socket, since the right socket would still
    be open.

    pkg/proc: configure target to not clear stepping breakpoints (#2635)

    In order for DAP to support halting the program (either manually or on a breakpoint) performing some action and then resuming execution, there needs to be a way to stop the program without clearing the internal breakpoints. This is necessary for log points and stopping the program to set breakpoints.

    The debugging UI makes it seem like a user should be able to set or clear a breakpoint at any time. Adding this ability to complete synchronous requests while the program is running is thus important to create a seamless user experience.

    This change just adds a configuration to determine whether the target should clear the stepping breakpoints, and changes the server to use this new mode. Using the new mode means that the DAP server must determine when it expect the next to be canceled and do this manually.

    Now that Delve has internal breakpoints that survive for long periods

    * proc,terminal,service: support stack watchpoints

    Adds support for watchpoints on stack allocated variables.

    When a stack variable is watched, in addition to the normal watchpoint
    some support breakpoints are created:

    - one breakpoint inside runtime.copystack, used to adjust the address
      of the watchpoint when the stack is resized
    - one or more breakpoints used to detect when the stack variable goes
      out of scope, those are similar to the breakpoints set by StepOut.

    Implements #279

    proc: move breakpoint condition evaluation out of backends (#2628)

    * proc: move breakpoint condition evaluation out of backends

    Moves breakpoint condition evaluation from the point where breakpoints
    are set, inside ContinueOnce, to (*Target).Continue.

    This accomplishes three things:

    1. the breakpoint evaluation method needs not be exported anymore
    2. breakpoint condition evaluation can be done with a full scope,
       containing a Target object, something that wasn't possible before
       because ContinueOnce doesn't have access to the Target object.
    3. moves breakpoint condition evaluation out of the critical section
       where some of the threads of the target process might be still

    * proc/native: handle process death during stop() on Windows

    It is possible that the thread dies while we are inside the stop()
    function. This results in an Access is denied error being returned by
    SuspendThread being called on threads that no longer exist.

    Delay the reporting the error from SuspendThread until the end of
    stop() and only report it if the thread still exists at that point.

    Fixes flakyness with TestIssue1101 that was exacerbated by moving
    breakpoint condition evaluation outside of the backends.

    There is already a lock on the actual buffered tracepoints collection
    within proc, and this method call doesn't do anything to mutate Target
    otherwise so we shouldn't be opening ourselves up for a race condition
    error or any other kind of parallelism problem.

    Additionally, with this lock we essentially can never get the data until
    the process has exited becuase `continue` will lock the target. This
    change allows us to get the buffered tracepoint information immediately
    and display it as the program is running.
