Using a fixed path as the default output binary means that executing
Delve twice in the same directory will cause the second invocation to
overwrite the output binary of the first instance of Delve, making the
restart command not work correctly.
Fixes#3345
Read the command line of the main target process as well as any other
process Delve attaches to in follow exec mode.
The command line can be viewed using the 'target list' command.
In follow exec mode this command line is used to match the follow exec
regex to decide whether or not to attach to a child process.
On macOS or when using rr the list of arguments is not available for
attached processes since there is no way to use the gdb serial protocol
to read it.
Fixes#2242
A series of interconnected changes to both the terminal command
'config', DAP command 'dlv config', quality of life improvements to how
substitute-path works, and better documentation.
- Let 'config substitute-path' show the current substitute path rules
- Add a -clear command to 'config substitute-path'
- Support 'config-debug-info-directories'
- rewrite SubstitutePath to be platform independent (see below)
- document path substitution more
Regarding the rewrite of SubstitutePath: the previous version used
runtime.GOOS and filepath.IsAbs to determine which filepath separator to use
and if matching should be case insensitive. This is wrong in all situations
where the client and server run on different OSes, when examining core files
and when cross-compilation is involved.
The new version of SubstitutePath checks the rules and the input path to
determine if Windows is involved in the process, if it looks like it is it
switches to case-insensitive matching. It uses a lax version of
filepath.IsAbs to determine if a path is absolute and tries to avoid having
to select a path separator as much as possible

The only part of the reloaded value that was used was the
Children. This caused a bug where the Time format string was
reloaded, but it was not being displayed.
Fixesgo-delve/delve#3342
The compiler produces ABI compatibility wrappers for some functions.
We have changed the support for breakpoints to allow a single logical
breakpoint to correspond to multiple physical breakpoints, take
advantage of that to set breakpoints on both the ABI wrapper and the
real function.
Fixes#3296
Unrecovered-panic and fatal-throw were no longer part of the breakpoint
list because starting in 37e44bf they were created before the logical
breakpoints map was switched to the logical breakpoints map of the
target group.
Adds the ability to automatically debug child processes executed by the
target to the linux native backend.
This commit does not contain user interface or API to access this
functionality.

Delve no longer compiles on Go1.12 and earlier, we don't test it on
these versions and they are 4 years old and unsupported. Remove some
code related to Go 1.12 and earlier, mostly from tests.
This patch allows users to set a breakpoint even when the process has
exited. It will be left in a pending state until the process is
restarted.

- use PT_SUSPEND/PT_RESUME to control running threads in
resume/stop/singleStep
- change manual stop signal from SIGTRAP to SIGSTOP to make manual stop
handling simpler
- change (*nativeProcess).trapWaitInternal to suspend newly created
threads when we are stepping a thread
- change (*nativeProcess).trapWaitInternal to handle some unhandled
stop events
- remove misleading (*nativeProcess).waitFast which does not do
anything different from the normal wait variant
- rewrite (*nativeProcess).stop to only set breakpoints for threads of
which we have received SIGTRAP
- rewrite (*nativeThread).singleStep to actually execute a single
instruction and to properly route signals

This patch modifies the behavior of the exec subcommand such that
you don't necessarily have to write the "./" prefix when trying
to debug a precompiled binary in your working directory.
For example (given foo.test in working dir), before this change:
dlv exec foo.test
Would result in an error, forcing the user to type:
dlv exec ./foo.test
This just makes things a bit more convenient.
Adds field to breakpoint struct to track how a breakpoint was
originally set, moves the logic for disabling and enabling a breakpoint
to proc.
This will allow creating suspended breakpoints that are automatically
enabled when a plugin is loaded. When follow exec mode is implemented
it will also be possible to automatically enable breakpoints (whether
or not they were suspended) on new child processes, as they are
spawned.
It also improves breakpoint restore after a restart, before this after
a restart breakpoints would be re-enabled using their file:line
position, for breakpoints set using a function name or a location
expression this could be the wrong location after a recompile.
Updates #1653
Updates #2551
Changes FindLocation to support multiple targets and adds an AddrPid
member to api.Breakpoint so that clients can set breakpoints by address
when multiple targets are connected (but at them moment this field is
ignored).
Updates #1653
Updates #2551
The logical breakpoints map was created as a side effect of
createUnrecoveredPanicBreakpoint or createFatalThrowBreakpoint, however
with an executable with incomplete debug info (that must be incomplete
in just the right way) both will fail and the logical breakpoint map
will never be created.
It's unknown how such an executable could be created, one easy way is
to debug a non-go executable.
Fixes#3114
Go 1.20 switched to uint64 to represent goroutine IDs, we can't
actually follow suit because we have allowed clients to use -1 to refer
to the currently selected goroutine, however we should at least switch
to int64 and also update the rtype check to accept the 1.20 type.
This changes adds the support to replace relative paths sources with "" as rapresenting current directory.
For example:
Rule like '{from: "", to: "/my/project"}' will map path "src/my/code.go" into "/my/project/src/my/code.go"
Rule like '{from: "/my/project", to: ""}' will map path "/my/project/src/my/code.go" into "src/my/code.go"
Fixes#3082
Change service/debugger.(*Debugger).state and collectBreakpointInfo
methods so that they work with TargetGroup.
Updates #2551
when running custom builds
abstraction
on '5660f9a4'.
This patch removes the old error-prone way of tracking
whether the tracepoint is for a function entry or
return. Instead of trying to guess, let the data structure
simply tell us directly.
service/dap: fix indexing bug for maps
There was a bug that cut off the second half of a map, because the
number of variables was not accurately reported to the client.

In order to support substituting a single file within
a larger package, and not substituting a directory wholesale,
this commit introduces the ability for SubstitutePath
to replace individual file paths if there is an exact match.
This behavior is backwards-compatible with the previous
configuration.
Fixes#3074
Due to dyanmically loaded libraries there could be aribitrarily large
gaps in the address space, between functions. Limit the memory size we
are willing to disassemble.
Fixes#3040
Introduces a new TargetGroup abstraction that can be used to manage
multiple related targets.
No actual management of child processes is implemented here, this is
just a refactoring to make it possible to do that in the future.
Updates #2551
Go 1.19 also formats doc comments according to the new godoc syntax.
Some of our comments, especially unexported symbols did not conform to
the godoc syntax and therefore are mangled by 'go fmt'.
This PR runs 'go fmt' from go1.19 on everything and manually fixes the
problems.

Moves variable evaluation tests to pkg/proc which is where most of the
code they test exists, this also allows the removal of a bunch of
duplicate support code.
Fix pretty printing for CPU register components (created with the
XMM0.uintN syntax) while using format strings
Also fixes printing large literal constants with format strings.
Fixes#3020
Adds a LogicalBreakpoint type to represent logical breakpoints
explicitly. Until now logical breakpoints were constructed implicitly
by grouping physical breakpoints together by their LogicalID.
Having logical breakpoints represented explicitly allows for a simpler
implementation of disabled breakpoints, as well as allowing a simple
implementation of delayed breakpoints (#1653, #2551) and in general of
breakpoints spanning multiple processes if we implement debugging
process trees (#2551).
