While using grep_log it is useful to have a possibility to go through crashed
instance log.
Usage in case of crashed instance:
test_run:grep_log(nil, str-to-find, nil, {path=path_to_log})

Closes #196

The patch looks okay, but I would ask you to do few small modifications
(see below).

WBR, Alexander Turenko.

Please, keep a commit message body within 72 symbols.

Nit: It is rule of thumb to fit comments within 66 symbols.

We already use 'filename' name for this, I would use it for the option
too.

I suggest the following pattern for options:

 | local function f(<...>, opts)
 |     local opts = opts or {}
 |     local foo = opts.foo (or <default_value> if it is not nil)
 |     local bar = opts.bar
 |     <...the rest code...>
 | end

This way it is easy to find them all in code at one glance.

Hi! Thanks for the review.

I have looked thought the patch and fixed it.

You can look at diffs below.

To search custom logs filename option of grep_log can be used.
Usage: grep_log(self, node, waht, bytes, {filename = XXX})

Closes #196

@Changelog
Search custom log grep_log(self, node, waht, bytes, {filename = XXX})

Pushed to test-run with changes in the commit message (see below).
Updated the submodule in tarantool on the following branches: master,
2.3, 2.2, 1.10.

CCed Kirill.

WBR, Alexander Turenko.

Removed 'test_run:' prefix. It is convenient to determine a repository
in tarantool-patches mailing list, but have no much sense in the commit
itself (because it is already in test-run repository).

I suggest to use '--subject-prefix' option for 'git format-patch' when
preparing changes for a repository other then tarantool.

Expanded the description a bit:

 | The option can be used when it is not possible to grab 'box.cfg.log'
 | value from a tarantool instance: say, when the instance is stopped or
 | crashed.


> Usage: grep_log(self, node, waht, bytes, {filename = XXX})

Fixed typo: waht.

I rewrote it a bit to avoid confusion with self / colon and so:

 | Usage:
 |
 |  | local test_run = require('test_run').new()
 |  | test_run:grep_log(node, what, bytes, {filename = <...>})

> 
> Closes #196
>

> Search custom log grep_log(self, node, waht, bytes, {filename = XXX})

Removed the changelog entry from the commit message. It should be in a
email (at least for tarantool), but should not be part of a commit
message.
