Fixes NODE_OPTIONS when spaces are escaped #24065

@arcanis arcanis commented Nov 3, 2018

This PR fixes #12971. It adds a way to properly escape spaces when found within NODE_OPTIONS. The previous behavior was problematic because there was no way to use --require with paths containing spaces.

Can you maybe also add tests for what happens when a backslash is not followed by a space character? In particular, I’m thinking about Windows-style paths with \ in them

@addaleax will add a test - with this PR such paths would have to be escaped (C:\foo will be interpreted as C:foo), would that be acceptable? There's unfortunately a slight risk to break something.

@arcanis Yes, that would make this a breaking change in its current form…

@addaleax would it be semver-minor and acceptable if I was instead to add support for double quotes? Basically, doing the following:

NODE_OPTIONS='--require foo bar'
# execArgv=['--require', 'foo', 'bar']

NODE_OPTIONS='--require "foo bar"'
# execArgv=['--require', 'foo bar']

NODE_OPTIONS='--require foo\ bar'
# execArgv=['--require', 'foo\\', 'bar']

NODE_OPTIONS='--require C:\a\b\c'
# execArgv=['--require', 'C:\\a\\b\\c']

NODE_OPTIONS='--require "foo\ bar"'
# execArgv=['--require', 'foo bar']

NODE_OPTIONS='--require "foo\\ bar"'
# execArgv=['--require', 'foo\\ bar']

@arcanis I guess the question is whether people currently (successfully) use quotes for NODE_OPTIONS – I can’t really imagine why, but there could be cases where it gets tricky?

(I’m also kinda surprised by your first example, I’d probably expect '--require "foo bar"' to work like shell quoting, i.e. foo bar as a single argument to --require…)

In any case, I’m not more of an authority on “how people use node features” than anybody else, and other people can weigh in too.

@Trott This is related to the comment left by @addaleax here #24065 (review). There are three possible solutions:

  • fix the tests to double-escape the path (replace c:\foo\bar by c:\\foo\\bar)
  • remove support for escaping non-space and non-backslash characters (meaning that \a would stay as \a, and \\ would be collapsed into \)
  • make the parsing logic more complex to support pseudo-strings (c:\foo\bar would be parsed as-is because not quoted, and "c:\foo\bar" would be interpreted as c:foobar because quoted)

I think I'd lean towards either the second or third solutions .. they're not perfect, but changing behavior like this even in a major might be potentially painful otherwise.

I made my way here because I tried to use NODE_OPTIONS with--require with a quoted path and noticed Node didn't handle it. Quotes where the thing I reached for.

My preference is for seeing if the following is doable:

make the parsing logic more complex to support pseudo-strings

arcanis commented Mar 9, 2019

The latest commit changes the implementation to parse a JSON-like string (JSON-like because it really only take " and \ into consideration). It has a better backward compatibility (the only break would be if someone was using " within NODE_OPTIONS), and fixes #26521.

// [0] is expected to be the program name, fill it in from the real argv.
env_argv.push_back(argv->at(0));

bool is_in_string = false;

we have SplitString(), why don't just fix then use it?

I'm not sure that SplitString should contain an actual parsing logic, or double quote/backslash support, does it?

For reference this is the other place where SplitString is used - while it wouldn't be broken by using the same logic, in this case it sounds like it would be slightly overkill:

SplitString(per_process::cli_options->trace_event_categories, ',');

But I think it is necessary to abstract common functions like SplitString and we should maintain these functions instead of hacking code everywhere

If they have the same semantical requirements I'm all for it, but in this case it just doesn't seem the case? I can abstract this behavior in a separate function (SmartSplitString), but it'll eventually be used in a single place.

@arcanis I think having a common function is probably a good idea. How about SplitString check's the delimiter specified and does the new logic only if it is a space? In that way we still have a common function which will do the right thing if you use a space, but otherwise we don't have extra overhead?

Landed in 3ef1512, thanks for the PR and sorry it took so long to get it landed!

addaleax pushed a commit that referenced this pull request Apr 17, 2019
The characters specified within NODE_OPTIONS can now be escaped, which
is handy especially in conjunction with `--require` (where the file path
might happen to contain spaces that shouldn't cause the option to be
split into two).

Fixes: #12971

The characters specified within NODE_OPTIONS can now be escaped, which
is handy especially in conjunction with `--require` (where the file path
might happen to contain spaces that shouldn't cause the option to be
split into two).

Fixes: nodejs#12971

PR-URL: nodejs#24065
