[Bug] parsing of environment from preconfigure script fails with bash exported functions or multiline environment variables

[diego-santacruz]

Brief Issue Summary

Bash exported functions are exported to the environment with the BASH_FUNC_ prefix as multiline variables. But the parsing of the printenv output in applyEnvironment() does not support multiline variables.

As a result, partial function definitions are saved to the environment and then running any commands via bash fails as bash complains about syntax errors importing function definitions, like this.

/bin/sh: which: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `which'
/bin/sh: module: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `module'
/bin/sh: switchml: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `switchml'
/bin/sh: scl: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `scl'
/bin/sh: ml: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `ml'

If someone uses multiline environment variables a similar problem will occur: the parsed variable values will be incomplete.

Although multiline environment variables are rare, using printenv -0 would output NUL separated variables, instead of newline, with which it should be easy to add robust support for multiline environment variables in applyEnvironment().

Hi @diego-santacruz , thank you for reporting this issue. In order for us to investigate this further, could you please provide a sample project and repro steps to us that can reproduce this issue? Thanks.

[diego-santacruz]

Here you have a bare bones hello world project which exhibits this issue: makefile-tools-issue-754.tar.gz

The preconfigure.sh script defines a dummy function (test_function) that is exported, a simple variable (TEST_VAR) and a multiline variable (MULTILINE_VAR).

The output from Makefile Tools when running "Makefile: Clean Configure" is below; in the output you can see the following error

/bin/sh: test_function: line 1: syntax error: unexpected end of file
/bin/sh: error importing function definition for `test_function'

Note that the output of printenv includes the following.

MULTILINE_VAR=this
is
a
multiline
variable
TEST_VAR=foobar
BASH_FUNC_test_function%%=() {  echo "this is a test function"
}

Note that in my environment there are other exported shell functions inherited from the default Linux environment, itself, like scl, which, ml, etc., so those show errors as well.

This is the complete output from Makefile Tools.

And the output of build is the following, where you can see same errors from the shell.

 *  Terminal will be reused by tasks, press any key to close it. 

Note that in this case the build succeeds despite the error messages, but in more complex setup it does not (e.g., in our case were we use a Yocto cross-compile SDK for which we initialize the environment in a preconfigure script).

Just in case my bash version is 4.4.20.

[yanghhhhhhh]

@diego-santacruz Thank you for the detailed information. We can see that the build output contains error messages, but these are not displayed in the output window (Makefile Tools). Please refer to this video. If we missed something, please let us know. We look forward to hearing from you. Thanks.

Hi, this bit that I pasted in my previous comment is from the output window in Makefile tools. Also, by looking at the code in applyEnvironment() and the output of printenv I pasted above it is clear that applyEnvironment() will choke on any environment variable that has newlines embedded in its value, like it happens with bash exported shell functions (at least on some bash versions).

@diego-santacruz Thanks for your reply. Our Makefile Tools output window still doesn't show these errors. They only show the errors when displaying build information in Terminal. Could you please check the repro video above and tell us what steps we've missed? Thanks.

[diego-santacruz]

I checked the video, and the steps seem good. One step that you may want to add it to remove any cached state and reload the VS code window, otherwise you may see results from earlier. In my environment (remove VS code) I cleaned up the cached state with
rm -rf ~/.vscode-server/data/User/workspaceStorage/*/ms-vscode.makefile-tools

In any case, the fact that the error shows also in the build output window clearly shows that the environment Makefile Tools passes to make is not valid.

[yanghhhhhhh]

Hi @diego-santacruz , thank you for your reply.
Reproduced this issue on VS Code 1.105.0 + Makefile Tools v0.12.17 release version.

Repro Steps:

1. Download the attached project and open it (makefile-tools-issue-754.tar.gz).
2. Run command "Makefile: Clean and build the target All", observe the result.

Details please see following video:
