sdb's Introduction

SDB: Mono Soft Debugger Client

SDB is a command line client for Mono's soft debugger, a cooperative debugger that is part of the Mono VM. It tries to be similar in command syntax to tools such as GDB and LLDB.

Building

Building and using SDB requires a basic POSIX-like environment, a Bash-like shell, the libedit library (or an API/ABI-compatible replacement), and an installed Mono framework.

First, clone the submodules:

$ git submodule update --init --recursive

To build, run:

$ make

If the build succeeds, you can install SDB with:

$ make install

(You may need to invoke it with sudo or some such command.)

You can also run SDB from within the build directory by appending it to PATH and invoking sdb-dev. This is mainly intended for development of SDB itself. An example:

$ export PATH=`pwd`/bin:$PATH
$ sdb-dev
Welcome to the Mono soft debugger (sdb 1.0.5058.39468)
Type 'help' for a list of commands or 'quit' to exit

(sdb)

You can run the SDB test suite with:

$ make check

(This requires an F# installation.)

The following variables can be set in your environment or on the make command line to affect the build:

CAT: Path to the cat POSIX utility.
CD: Path to the cd POSIX utility.
CHMOD: Path to the chmod POSIX utility.
CP: Path to the cp POSIX utility.
ECHO: Path to the echo POSIX utility.
FSHARPC: Which F# compiler executable to use.
FSHARPC_FLAGS: Flags to pass to the F# compiler.
FSHARPC_TEST_FLAGS: Flags to pass to the F# compiler for tests.
GENDARME: Which Gendarme executable to use (optional).
GENDARME_FLAGS: Flags to pass to Gendarme.
INSTALL: Path to the install POSIX utility.
MCS: Which C# compiler executable to use.
MCS_FLAGS: Flags to pass to the C# compiler.
MCS_TEST_FLAGS: Flags to pass to the C# compiler for tests.
MKDIR: Path to the mkdir POSIX utility.
NUGET: Which NuGet executable to use.
PKG_CONFIG: Path to the pkg-config utility.
RM: Path to the rm POSIX utility.
SED: Path to the sed POSIX utility.
TAR: Path to the tar POSIX utility.
MSBUILD: Which MSBuild executable to use.
MSBUILD_FLAGS: Flags to pass to MSBuild.

Additionally, MODE can be set to Debug (default) or Release to indicate the kind of build desired. PREFIX can be set to specify the path that the install and uninstall targets should operate within (defaults to /usr/local).

Finally, MONO_PREFIX and MONO_BINARY can be set to tell the check target which Mono executable should be used. See the description of RuntimePrefix and RuntimeExecutable further down for more information.

Usage

Running a program is simple:

$ cat test.cs
using System;
using System.Diagnostics;

static class Program
{
    static void Main()
    {
        var str = "Foo!";

        Foo(str);
    }

    static void Foo(string str)
    {
        Console.WriteLine(str);

        Bar();
    }

    static void Bar()
    {
        Debugger.Break();
    }
}
$ mcs -debug test.cs
$ sdb
Welcome to the Mono soft debugger (sdb 1.0.5060.15368)
Type 'help' for a list of commands or 'quit' to exit

(sdb) r test.exe
Inferior process '5234' ('test.exe') started
Foo!
Inferior process '5234' ('test.exe') suspended
#0 [0x00000001] Program.Bar at /home/alexrp/Projects/tests/cs/test.cs:22
        Debugger.Break();

A stack trace can be generated with bt:

(sdb) bt
#0 [0x00000001] Program.Bar at /home/alexrp/Projects/tests/cs/test.cs:22
        Debugger.Break();
#1 [0x00000007] Program.Foo at /home/alexrp/Projects/tests/cs/test.cs:17
        Bar();
#2 [0x00000008] Program.Main at /home/alexrp/Projects/tests/cs/test.cs:10
        Foo(str);

We can select a frame and inspect locals:

(sdb) f up
#1 [0x00000007] Program.Foo at /home/alexrp/Projects/tests/cs/test.cs:17
        Bar();
(sdb) p str
string it = "Foo!"

Or globals:

(sdb) p Environment.CommandLine
string it = "/home/alexrp/Projects/tests/cs/test.exe"

To continue execution, do:

(sdb) c
Inferior process '5234' ('test.exe') resumed
Inferior process '5234' ('test.exe') exited
(sdb)

We can then exit SDB:

(sdb) q
Bye

For more commands, consult help in SDB.

Options

SDB has a few command line options that are useful for automation. For the full list, issue sdb --help.

First of all, all non-option arguments passed to SDB are treated as commands that SDB will execute at startup. For instance:

$ sdb "run test.exe"

Or:

$ sdb "args --foo --bar baz" "run test.exe"

This starts SDB and immediately executes test.exe with the given arguments.

The first option is -f. This option specifies files that SDB should read commands from. These commands are executed before any commands specified as non-option arguments. This option is useful for longer command sequences that are easier to maintain in a separate file. Example:

$ cat cmds.txt
args --foo --bar baz
run test.exe
$ sdb -f cmds.txt

The second option is -b. This runs SDB in batch mode; that is, it will exit as soon as all commands have finished and no inferior process is running. This goes well with -f for running programs regularly under SDB.

Settings

One configuration element that you almost certainly need to alter is the RuntimePrefix string value. It is set to /usr by default, regardless of OS, which is probably not desirable everywhere. For example, on Windows, you will want to set it to something like C:\Program Files (x86)\Mono-3.0.10. Or if you have Mono in some other directory, you might set it to e.g. /opt/mono.

The RuntimeExecutable element is another way to specify which Mono executable to use. If RuntimePrefix is empty, then RuntimeExecutable is taken as the full path to the Mono executable. If both elements are non-empty, they are combined as Path.Combine(RuntimePrefix, "bin", RuntimeExecutable). This configuration element is useful for switching between mono32 and mono64 on OS X in particular.

You may want to set DisableColors to true if you don't want the fancy ANSI color codes that SDB emits.

Finally, three useful settings for debugging SDB itself exist: DebugLogging can be set to true to make SDB spew a bunch of diagnostic information. LogInternalErrors can be set to true to log any internal errors that are encountered in the Mono debugging libraries. LogRuntimeSpew can be set to true to log all messages from the Mono VM.

Paths

When configuration elements are changed with config set, SDB will store the configuration data in ~/.sdb.cfg. The content of the file is the .NET binary serialization of the Mono.Debugger.Client.Configuration class. This file is read on startup if it exists.

At startup, SDB will scan the ~/.sdb directory for plugin assemblies. It will attempt to load all command definitions.

Finally, SDB will read ~/.sdb.rc and execute any commands (one per line) from it. This is useful if you prefer to change your settings with commands that you write down manually, rather than storing the data in a binary file.

Environment

The SDB_COLORS variable can be set to disable to tell SDB to not use colors in output. Normally, SDB will not use colors if it detects that stdout has been redirected, that TERM is set to dumb (or not set at all), or if the DisableColors configuration element is true.

SDB_CFG can be set to a specific configuration file to use instead of the default ~/.sdb.cfg. If set to the empty string (i.e. SDB_CFG="" sdb), SDB will not load any configuration file at all, and changed configuration values will not be saved.

The SDB_PATH variable can be set to a list of additional directories that SDB will scan for plugin assemblies in. Each directory should be separated by a semicolon (Windows) or a colon (POSIX).

SDB_DEBUG can be set to enable to make SDB print diagnostic information while debugging. This may be useful to debug SDB itself.

Plugins

At the moment, SDB has one extension point which is the Mono.Debugger.Client.Command class and the related Mono.Debugger.Client.CommandAttribute class. A class implementing Command that is tagged with CommandAttribute will be instantiated at startup time and put into the root command list.

For SDB to find custom commands, they should be compiled into .dll assemblies and put in ~/.sdb (or some other directory specified in SDB_PATH). Plugin assemblies can also be loaded manually with the plugin command.

Here's an example of compiling and using a test plugin:

$ cat test.cs
using Mono.Debugger.Client;

[Command]
public sealed class MyCommand : Command
{
    public override string[] Names
    {
        get { return new[] { "mycmd" }; }
    }

    public override string Summary
    {
        get { return "Performs magic."; }
    }

    public override string Syntax
    {
        get { return "mycmd"; }
    }

    public override string Help
    {
        get { return "Some sort of detailed help text goes here."; }
    }

    public override void Process(string args)
    {
        Log.Info("Hello! I received: {0}", args);
    }
}
$ mcs -debug -t:library test.cs -r:$(dirname $(which sdb))/../lib/sdb/sdb.exe -out:$HOME/.sdb/test.dll
$ sdb
Welcome to the Mono soft debugger (sdb 1.0.5061.14716)
Type 'help' for a list of commands or 'quit' to exit

(sdb) h mycmd

  mycmd

Some sort of detailed help text goes here.

(sdb) mycmd foo bar baz
Hello! I received: foo bar baz

You can look at SDB's own command classes for some examples of things that you can do in your commands.

sdb's Issues

Make configuration extensible

Basically, plugins should be able to declare configuration variables which are stored in a dictionary on Configuration. The cfg commands should be able to work with these.

Does not work on windows because of Mono.Posix dependency

Hey I'm trying to use sdb on windows but it started screaming about that it couldn't load assembly Mono.Posix. So I tried installing gtksharp and copied its Mono.Posix.dll to the directory with sdb.exe. However this didn't work either and is now screaming at me like this:


Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'Mono.Posix, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
   at Mono.Debugger.Client.Program.Main(String[] args)

Installation issue ( git not working, make missing a project file )

Hello,

I apologize if this is way stupid, but I am new to Linux, new to programming and C# in particular. On the flip side I don't like MonoDevelop at all and I wish to compile and debug manually. So many many thanks to all of you smart people making this possible, however I have an installation problem. I can not understand how to properly use the 'git' command and this is ( I presume ) causing make to yell that it is missing Project file "debugger-libs.sln". Would you mind to help out?

Thanks,
Alex

sdb doesn't seem to build on Windows

TL;DR:

Following the instruction in the README, I fail to build sbt because of the error Too many project files specified
I can bypass this error if I remove /nologo from the switches, but it seems I build a corrupted executable since it fails make check and outputs Failed to connect to 'test.exe' whenever I try to use it

I'm trying to build sdb on my Windows [1].

If I run make just after cloning the repo and the submodules, I get

mkdir -p bin                                                                                                       
cp LICENSE bin/LICENSE                                                                                             
mkdir -p bin                                                                                                       
cp README.md bin/README                                                                                            
cd dep/debugger-libs && xbuild /verbosity:quiet /nologo /property:Configuration=net_4_0_Debug debugger-libs.sln    
MSBUILD: error MSBUILD0004: Too many project files specified                                                       
make: *** [bin/ICSharpCode.NRefactory.dll] Erreur 1

using msbuild instead, with make XBUILD=msbuild.exe yields a similar error:

MSBUILD : error MSB1008: Only one project can be specified. 
Switch: debugger-libs.sln

(I get the same error if I run the following commands manually

cd dep/debugger-libs
msbuild.exe /verbosity:quiet /nologo /property:Configuration=net_4_0_Debug debugger-libs.sln

)

It appears I can bypass this issue if I remove /nologo from the switches. I have no idea why it fixes the issue, but running make XBUILD_FLAGS='/property:Configuration=net_4_0_Debug /verbosity:quiet' successfully builds

(It might be worth noticing that when it builds dep/debugger-libs, it outputs the warning

warning CS1685: The predefined type `System.Runtime.CompilerServices.ExtensionAttribute' is defined multiple times. Using definition from `mscorlib.dll'

)

However, running the tests (make check FSHARPC=fsc) fails, with the errors (which I'm unable to output in English) :

fsc --debug+ --nologo --warnaserror --keyfile:mono.snk --out:chk/check.exe --target:exe chk/check.fs

Suspending after having stepped thru code does not work well

I was trying to set a break point after having stepped thru code. I used Ctrl-c. SDB told me teh process was supsended but did not give the usual prompt. Pressing Ctrl-C again gives a warning and the prompt. However any command i type in does not get executed by SDB.

Instruction stepping steps multiple instructions

I'm not sure if this is a bug in this project or this one, but instruction single stepping (using step into instruction or step over instruction) works unreliably for me. Often, it will skip over multiple instructions instead. For example, here SDB skips an entire call to System.Type:GetTypeFromHandle and instead jumps into System.Reflection.Assembly.GetAssembly:

Am I doing something wrong here, or is there any reason SDB might be behaving this way? The number of instructions it skips seems to be a random number (especially if the next instruction is a call or callvirt) as well so I'm not sure what's going on.

watch command displays duplicate

Hello! I'm callmekohei!

Problems summary

watch command displays duplicate

(sdb) watch
#0 's': string it = "aaa"
#0 's': string it = "aaa"

like this

Expected

Support parameter types in method breakpoints

This will be somewhat tricky since we might have to parse a full C# method declaration...

I want to use addCommand (^_^)/

Hello! I'm callmekohei!

Problem

I can not use addCommand.

Expected behavior

I can use addCommand

Like this

[<Sealed; Command>]
type MyCommand() =
    inherit Command()
    override __.Names   = [|"mycmd"|]
    override __.Summary = "aaa bbb ccc"
    override __.Syntax  = "ddd eee fff"
    override __.Help    = "Help Help Help"
    override __.Process(args) =

        AddCommand<StepOverCommand>()  // <---- step over

        // run my code after running step over
        Log.Info("hello world")

work around

(sdb) do , step over , mycmd

reason

Take time to input when we use sdb on command-line.
Flickering screen

like this

Support GDB-like command line arguments

In particular, it would be nice to have something like GDB's --args.

Switch to XML for configuration-like files

For 2.0, we should switch the serialization format used for the debugger database and the configuration file to XML. Humans can't really edit the current format.

Fix the atrocious exception printing hack

Depends on: mono/debugger-libs#11

The current code: https://github.com/mono/sdb/blob/master/src/Debugger.cs#L170

[QUESTION] Does SDB comply to GDB's machine interface?

I don't know if this is the right place to ask this question, but I could not find any info on this topic.

Does SDB comply to GDB's machine interface?

I ask because of Microsoft/MIEngine and remote debugging a mono project from inside Visual Studio?

Xamarin + sdb samples

Would it be possible to show how to debug xamarin apps with sdb?

Noticed this was Xamarin + sdb #8

Building an iOS or Android app should give relevant .exe and .mdb files but I'm not sure how to connect the dots to get it working end to end.

Thanks!

Invalid string to bash in env

I'm not really sure what is the reason but here's what's happening:

cloned the repo
make && sudo make install
run sdb

Then I get the following

/usr/bin/env: ‘bash\r’: No such file or directory

I'm using mono on Linux Mint and my suspicion is that this is a problem with line endings, given Windows's \r\n and Unix's \n.

Using sdb with Emacs GUD

Hi,

I would like to use sdb together with Emacs (25.1.1) in GUD mode. When I run sdb on the command line, the debugger starts up fine. However, when I start GUD with sdb as command, I see the following exception:

Welcome to the Mono soft debugger (sdb 1.5.6151.25963)

Unfortunately, there is not much information out there documenting this setup. Is there any way to make sbd and Emacs play nice with each other?

Thanks,

Extra space after sdb prompt

Hi! There's a usability issue I'm having that's making it rather impossible to use sdb: the cursor has a bunch of spaces between it and the (sdb) prompt. This is a critical problem because if I arrow up, the space is not added and the characters displayed don't match up with the ones I'm editing.

Here is a screenshot of the misbehaviour, from konsole (though it's also shown up in alacritty):

I just built this sdb from the master branch today, 7a408a0. I'm running this mono version on Arch Linux:

Implement process attach support

Breakpoint paths should be converted to full paths

This is needed since certain relative paths (without a leading ./) don't seem to work.

Implement command completion

Additional breakpoint features

I frequently use breakpoints, coupled with expression evaluation features, in other debuggers to alter control flow. I was trying to do the same thing in SDB but couldn't figure out how to do so–I'm not sure if SDB has these features or if I just can't find them. One way I do something like this is by setting breakpoints on individual instructions and then evaluating expressions (to change condition variables) and resuming execution. Does SDB support doing things like this? (Specifically, can I set a breakpoint on a specific instruction in a method and add debugger commands to it that run whenever it gets hit?)

Cannot build due to dependency on xbuild

The sdb makefile depends on xbuild, but mono no longer ships it - only msbuild.

Won't compile using parallel make (-j9)

I detected this while adding mono/sdb to my buildroot setup. It seems that there's some dependency problem if make is executed using multiple jobs (HEAD: b8b3296):

Cannot build on Linux Mint

I must be doing something wrong, but I'm new to Mono and can't seem to get sdb to build.

I've tried googling for the error messages, but come up empty. Am I missing some kind of dependency?

$ cd sdb
$ git submodule update --init --recursive
$ make

Implement decompilation

Ideally, we'd use ICSharpCode.Decompiler if/when it's separated into its own Git repository.

Failure to inspect global variables while suspended in unmanaged

public static void Main (string[] args) { while (true) Thread.Sleep (1000); }
Running this code under sdb and forcing a stop (Ctrl C). If we are in the top frame we fail to inspect global variables ex : print System.Environment.CommandLine. Failing with Result is unrepresentable (Unknown, ReadOnly)

Probably unrelated, I can also get exceptions Mono.Debugger.Soft.VMNotSuspendedException: The vm is not suspended. when suspended in other unmanaged code (like Monitor.Enter)

Make Ctrl-C work

Support setting next statement/instruction

Depends on this: mono/debugger-libs#23

Create a csproj/sln file

I think there should be a csproj/sln file associated with this project so that tools such as omnisharp can be used for code completion.

Prompt is printed strangely when using Mono.Terminal and with colors enabled

A bunch of extra white space is added after the prompt. Only happens when colors are enabled. Seems to happen on all OSs when Mono.Terminal is used.

Support type visualizer plugins

This will most likely require some sort of support in Mono.Debugging.

Stdout in sdb plugin

Hello, I'm callmekohei!

Problem

I want to display app's stdout in sdb plugin.

code

open Mono.Debugger.Client
open Mono.Debugging.Client

open System.IO

[<Sealed; Command>]
type MyCommand() =
    inherit Command()
    override __.Names   = [|"mycmd"|]
    override __.Summary = "aaa bbb ccc"
    override __.Syntax  = "ddd eee fff"
    override __.Help    = "Help Help Help"
    override __.Process(args) =

    Log.Info("-----------------")

    /// I want to display app's stdout!
    ????

    Log.Info("-----------------")

I'm happy to have a tip (^_^)/

Cannot use `make` to build sdb library [Question]

Hi,
In the README.md you write:

First, clone the submodules:
$ git submodule update --init --recursive
To build, run:
$ make

I have problems running the make - command prompt says the make command doesn't exist.
Perhaps I am missing something fundamental, would be appreciated if someone could help me so I can use the debuggin tools.
Thanks in advance,
Alexander

Is it possible to debug NUnit tests?

I tried to do so under Ubuntu with the following command:

sdb "args debug-test.dll" "run nunit3-console.exe"

I put a System.Diagnostics.Debugger.Break() inside a test, but it does not break there. NUnit runs successfully to the end instead. I surely missed something here or isn't it possible at all?

Support catchpoints that don't include subclasses

Depends on: mono/debugger-libs#79

Can I change a variable value?

Hello! I'm callmekohei!

So I want to change a valiable value daynamically.

Fall back to disassembly when no source is available

Depends on: mono/debugger-libs#24

When no source is available, we should fall back to disassembly in stack traces and the like.

It would also be worth having a PreferDisassembly configuration option that would make us always use disassembly.
