* proc/core: off-by-one error reading ELF core files core.(*splicedMemory).ReadMemory checked the entry interval erroneously when dealing with contiguous entries. * terminal,service,proc/*: adds dump command (gcore equivalent) Adds the `dump` command that creates a core file from the target process. Backends will need to implement a new, optional, method `MemoryMap` that returns a list of mapped memory regions. Additionally the method `DumpProcessNotes` can be implemented to write out to the core file notes describing the target process and its threads. If DumpProcessNotes is not implemented `proc.Dump` will write a description of the process and its threads in a OS/arch-independent format (that only Delve understands). Currently only linux/amd64 implements `DumpProcessNotes`. Core files are only written in ELF, there is no minidump or macho-o writers. # Conflicts: # pkg/proc/proc_test.go

## dlv core
|
|
|
|
Examine a core dump.
|
|
|
|
### Synopsis
|
|
|
|
|
|
Examine a core dump (only supports linux and windows core dumps).
|
|
|
|
The core command will open the specified core file and the associated
|
|
executable and let you examine the state of the process when the
|
|
core dump was taken.
|
|
|
|
Currently supports linux/amd64 and linux/arm64 core files, windows/amd64 minidumps and core files generated by Delve's 'dump' command.
|
|
|
|
```
|
|
dlv core <executable> <core>
|
|
```
|
|
|

|
--api-version int Selects API version when headless. New clients should use v2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md. (default 1)
|
|
--backend string Backend selection (see 'dlv help backend'). (default "default")
|
|
--build-flags string Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"
|
|
--check-go-version Checks that the version of Go in use is compatible with Delve. (default true)
|
|
--disable-aslr Disables address space randomization
|
|
--headless Run debug server only, in headless mode.
|
|
--init string Init file, executed by the terminal client.
|

|
|
--log Enable debugging server logging.
|
|
--log-dest string Writes logs to the specified file or file descriptor (see 'dlv help log').
|
|
--log-output string Comma separated list of components that should produce debug output (see 'dlv help log')
|
|
--only-same-user Only connections from the same user that started this instance of Delve are allowed to connect. (default true)
|
|
-r, --redirect stringArray Specifies redirect rules for target process (see 'dlv help redirect')
|
|
--wd string Working directory for running the program.
