Issue: https://github.com/tarantool/tarantool/issues/5040
Branch: https://github.com/tarantool/tarantool/tree/artemreyt/gh-5040-interactive-mode-bug
CI: https://github.com/tarantool/tarantool/runs/1929677579

Previous patch version: https://lists.tarantool.org/pipermail/tarantool-patches/2021-January/022144.html

Changes in v2:
  * core:
    - added `part of #5040` to the commit message;
    - rename `errinj_scan_env()` -> `errinj_set_with_environment_vars()`;
    - whitespaces refactored;
    - add test for setting error injections via environment variables;
  * lua:
    - little code refactoring after Sergey Bronnikov review (renames and move
    includes in the alphabetical order);
    - fixed bug, when test failed under high concurrency. There were about 20
    fails with 100 workers. Now, it's ok, tested with 300 workers om CentOS and
    macOS.
    (Bug resolved with removing temporary output_file after each testcase iteration);
    - moved ChangeLog to the last commit.

Artem Starshov (2):
  core: add setting error injections via env
  lua: fix tarantool -e always enters interactive mode

Sometimes, it's useful to set error injections via environment
variables and this commit adds this opportunity.

e.g: `ERRINJ_WAL_WRITE=true tarantool` will be launched with
ERRINJ_WAL_WRITE setted to true.

Errinjs with bool parameters can should be set as "true", "TRUE",
"false" or "FALSE".

Errinjs with int or double parameters should be whole valid ("123s" is invalid).
e.g. for int or double: "123", "-1", "2.34", "+2.34".

Part of #5040

The reason why tarantool -e always enters interactive mode is that
statement after option -e isn't considered as a script.

In man PUC-Rio lua there are different names for statement -e (stat)
and script, but they have the same behavior regarding interactive
mode. (Also cases, when interpreter loads stdin, have the same behaviour).

Fixes #5040
---
@ChangeLog: Fixed -e option, when tarantool always entered interactive mode when
stdin is a tty. Now, `tarantool -e 'print"Hello"'` doesn't enter interactive mode
as it was before.

1. What happen if someone set boolean value to "False"?

May be it's worth to convert env_value to lowercase and then compare? 
The same question for "true".

2. variable name should reflect a purpose of variable.

name is about script file, when variable contains a path to a file.

1. according to name (ISATTY) variable can be in enabled or disabled 
state so

why do you use integer type here?

1. Done. Case-insensetive value can be set to env variable now.

1. I use integer type for ISATTY cause this injection "overrides" return 
value of

standard isatty function for stdin. It can be set to 0 or 1. Default 
value -1 means

to use return value of standard function.

Thanks!

It's worth to add different values for 'true'/'false' to test

for documentation and regression purposes.

Done, added tests for "true", "True", "TRUE" (same for false) and tests 
for numeric injections with plus and minus signs.

Updates you can see on the branch.

HI! Thank you for the patch.
Seems like write a test is more difficult than fixing the bug)
Generally OK.
I'll paste the last variation of the diff with comments.

Subject: [PATCH 1/2] core: add setting error injections via env
Cc: tarantool-patches@dev.tarantool.org

Sometimes, it's useful to set error injections via environment
variables and this commit adds this opportunity.

e.g: `ERRINJ_WAL_WRITE=true tarantool` will be launched with
ERRINJ_WAL_WRITE setted to true.

Errinjs with bool parameters can be set to "true", "false",
"True", "False", "TRUE", "FALSE", etc. (case-insensitive variable).

Errinjs with int or double parameters should be whole valid ("123s" is 
invalid).
e.g. for int or double: "123", "-1", "2.34", "+2.34".

Part of #5040

HI! Thank you for the patch.
Generally OK.
I'll paste the last variation of the diff with comments.

Subject: [PATCH 2/2] lua: fix tarantool -e always enters interactive mode
Cc: tarantool-patches@dev.tarantool.org

The reason why tarantool -e always enters interactive mode is that
statement after option -e isn't considered as a script.

In man PUC-Rio lua there are different names for statement -e (stat)
and script, but they have the same behavior regarding interactive
mode. (Also cases, when interpreter loads stdin, have the same behaviour).

Fixes #5040
