Subject: Re: [Tarantool-patches] [PATCH v2 1/5] error: Add a Lua backtrace to error
Date: Tue, 14 Apr 2020 03:11:42 +0200	[thread overview]
Message-ID: <ea40e81a-df85-39e6-01ea-2f9876689ce9@tarantool.org> (raw)
In-Reply-To: <e3ac4d221f1a2a513cbaf64fc429a84458b8e977.1586505741.git.lvasiliev@tarantool.org>

Thanks for the patch!

Sorry, some of my comments may contain typos, because it is
very late and I can't continue polishing it today.

First of all there are some major issues with the
patch, which IMO should be clarified before it is pushed.

1) Why do we need the traceback in scope of 4398? It has
nothing to do with marshaling through IProto, nor with
custom error types.

2) What to do with stacked errors? Currently only the first
error in the stack gets a traceback, because luaT_pusherror() is
called only on the top error in the stack. Consider this test:

    box.cfg{}
    lua_code = [[function(tuple)
                    local json = require('json')
                    return json.encode(tuple)
                 end]]
    box.schema.func.create('runtimeerror', {body = lua_code, is_deterministic = true, is_sandboxed = true})
    s = box.schema.space.create('withdata')
    pk = s:create_index('pk')
    idx = s:create_index('idx', {func = box.func.runtimeerror.id, parts = {{1, 'string'}}})

    function test_func() return pcall(s.insert, s, {1}) end
    box.error.cfg{traceback_enable = true}
    ok, err = test_func()


    tarantool> err:unpack()
    ---
    - traceback: "stack traceback:\n\t[C]: at 0x010014d1b0\n\t[C]: in function 'test_func'\n\t[string

    ... <snipped>

    tarantool> err.prev:unpack()
    ---
    - type: LuajitError
      message: '[string "return function(tuple)..."]:2: attempt to call global ''require''
        (a nil value)'
    ... <snipped>

The second error does not have a traceback at all.


See 10 comments below. Also I started a new branch with review
fixes to speed up the process. The branch is called

    lvasiliev/gh-4398-expose-error-module-4-review

You can find review fixes to this commit in the end of the
email and on this branch in a separate commit. Note, my branch
is rebased on master already. So some changes are related to
cleaning the mess after it.

1. We don't put links when issue is in the same repository.
We always use '#<number>' reference. This concerns this and all
next commits.

2. The option name is utterly overcomplicated. Just use

    traceback_enable

> Adding a traceback can be forced on creation.
> box.error.new({type = "CustomType", reason = "reason", traceback = true/false})

3. CustomType errors are not defined here, you can't use it in
the request description.

4. Please, don't put issue references inside docbot requests. This
concerns this and all next commits.

5. If something is not nil, it does not mean it is a boolean.
Better check lua_isboolean().

6. It makes no sense to call this function on a NULL 'e'. This
should be an assertion. As well as it is not possible to 'reset'
the trace, so e->lua_traceback should be always NULL here.

7. Also I don't think it is a good idea to call traceback attribute
'lua_traceback'. Because we won't have separated 'lua_traceback'
and 'c_traceback'. Anyway there will be always only one. Probably
with C and Lua mixed (it is possible via space triggers to mix Lua
and C in layers).

8. I don't think it is a good idea to add this to
every error object when there is no a trace. Just
leave it nil.

10. Usually every commit should add tests on the feature it
introduces. You didn't add any single test. Why?

Consider my review fixes below and on a new branch in a
separate commit. It solves all the code-related problems,
but I still don't know what to do with the major issues
described in the beginning.

Branch is:

    lvasiliev/gh-4398-expose-error-module-4-review

====================
    Review fixes
    
    New commit message proposal:
    
    error: add a Lua traceback to error
    
    Lua backtrace can be enabled for all errors using a server-wide
    option, or on a per-error basis using box.error() and
    box.error.new() arguments.
    
    Needed for #4398
    
    @TarantoolBot document
    Title: Lua error.traceback
    
    Lua error objects now feature 'traceback' optional attribute.
    It contains Lua traceback. C part is not present here.
    
    Traceback collection is a relatively expensive operation, so it
    is disabled by default. In case you need to enable it, there are
    2 options:
    
    * Global option `traceback_enable` for `box.error.cfg` call:
    ```
        box.error.cfg({traceback_enable = true})
    ```
    
    * Per object option, in case you want traceback only for certain
    cases:
    ```
        box.error.new({
            code = 1000,
            reason = 'Reason',
            traceback = true/false
        })
    ```
