Specific characters in path of parent directories of file causes debugger to crash.

[RokeJulianLockhart]

Summary

I've managed to break the path parsing. Specifically, including certain characters in the parent directories of the file being debugged causes the debugger to crash.

I don't know what specific characters cause this, but I'll update the report when(/if) I do.

Reproduction

1. Directory-Caused Crash

   The undermentioned path, which contains a normal filename (testfile.py) but an abnormally named immediate parent directory:

   /home/RokeJulianLockhart/Documents/  [-]	`{title: "Code",	id: ""}`{.JSON5}.dir/testfile.py

   ...causes ms-python.debugpy to crash:

   RokeJulianLockhart@sayw4i:~/Documents$  cd /home/RokeJulianLockhart/Documents/\ \ \[-\]\`\{title:\ \"Code\",id:\ \"\"\}\`\{.JSON5\}.dir ; /usr/bin/env /usr/bin/python3 /home/RokeJulianLockhart/.vscode-insiders/extensions/ms-python.debugpy-2024.11.2024082901-linux-x64/bundled/libs/debugpy/adapter/../../debugpy/launcher 47225 -- /home/RokeJulianLockhart/Documents/\ \ \[-\]\`\{title:\ \"Code\",id:\ \"\"\}\`\{.JSON5\}.dir/testfile.py

2. If I put the file deep enough (like this example) it completely breaks. Enter doesn't work because the path is incorrectly escaped, so ^C is necessary to exit the transient debug state:

   This causes Python Debugger: "Timed out waiting for launcher to connect"  #1677 to occur:

   

3. Debugger Functioning with Unusual Filename

   Note that this doesn't apply to the file's name. Consider the undermentioned example:

   /home/RokeJulianLockhart/Documents/. [-]	``{title: "`platform.uname()`{.Py} Field Output",	id: "sgskr5"}``{.JSON5}.txt.Py

   As the undermentioned "Terminal" log demonstrates, it functions:

   RokeJulianLockhart@sayw4i:~/Documents$  cd /home/RokeJulianLockhart/Documents ; /usr/bin/env /usr/bin/python3 /home/RokeJulianLockhart/.vscode-insiders/extensions/ms-python.debugpy-2024.11.2024082901-linux-x64/bundled/libs/debugpy/adapter/../../debugpy/launcher 38369 -- /home/RokeJulianLockhart/Documents/.\ \[-\]\        \`\`\{title\:\ \"\`platform.uname\(\)\`\{.Py\}\ Field\ Output\"\,\      id\:\ \"sgskr5\"\}\`\`\{.JSON5\}.txt.Py \`\`\{title:\ \"\`platform.uname\(\)\`\{.Py\}\ Field\ Output\",id:\ \"sgskr5\"\}\`\`\{.JSON5\}.txt.Py 
   for k, v in platform_uname_as_dict.items()
   system = Linux
   node = sayw4i
   release = 6.10.10-200.fc40.x86_64
   version = microsoft/vscode-python-debugger#1 SMP PREEMPT_DYNAMIC Thu Sep 12 18:26:09 UTC 2024
   machine = x86_64
   processor = 
   RokeJulianLockhart@sayw4i:~/Documents$

Environment

1. Filename Character Support

   One must be using a filesystem and OS that support such characters. I use BTRFS on Fedora 40, but anything comparable should work. ¹

2. Versions

   1. Code

      1. #!/usr/bin/env sh
         rpm -q 'code' 'code-insiders'

      2. code-1.93.1-1726079369.el8.x86_64

Miscellaneous

Potentially related to microsoft/vscode-python-debugger#233 (comment), although I doubt it, because /home/RokeJulianLockhart/Documents/Text File.txt.py works.

In retrospect, apologies for the insane examples. Luckily, I've managed to reduce the character set necessary to reproduce it. Specifically, the undermentioned path:

[]`{:"",: ""}`{.}

The sole difference is a single tab character, so it's a combination of the tab character and others which breaks parsing, because a directory name which is merely a tab ( ) does function, as the undermentioned log demonstrates:

#1671

Per #1677, I've attempted to collect some logs using this Stack Overflow answer.

Specifically, the aforereferenced most-compact-but-still-breaky path yet (undermentioned):

/home/RokeJulianLockhart/Documents/[]`{:"",	: ""}`{.}/test_file.py

...produces the undermentioned logs in the "Extension Host" (non-"Worker") console:

However, the aforementioned really-breaky-path doesn't create any logs when ^C'd.

[rchiodo]

Looking at the other issue, we seem to translate tab characters into an escaped tab. I would guess that's the root cause of this issue.

[debonte]

I'm not seeing it escaped, but rather stripped out. It happens before the path is given to debugpy. Not sure if this is a vscode-python-debugger issue, a vscode issue, or what.

#1671 (comment)

@rchiodo, indeed, it's the tabs. Working back from the right, I removed one character per test, and ascertained that []`{:"", works as a path:

RokeJulianLockhart@sayw4i:~/Documents/[]`{:"",  : ""}`{.}$  cd /home/RokeJulianLockhart/Documents/\[\]\`\{:\"\", ; /usr/bin/env /usr/bin/python3 /home/RokeJulianLockhart/.vscode-insiders/extensions/ms-python.debugpy-2024.11.2024092501-linux-x64/bundled/libs/debugpy/adapter/../../debugpy/launcher 37961 -- /home/RokeJulianLockhart/Documents/\[\]\`\{:\"\",/test_file.py 
test

...but []`{:"", doesn't:

@debonte, that last log appears to corroborate your observation - /home/RokeJulianLockhart/Documents/test_file.py is definitely not the correct path. Impressively, it even redacted the empty /.

The tab appears to get stripped out between the point where we send the runInTerminal request and where the launcher is actually started. I believe it has something to do with runInTerminal's call to prepareCommand. I tried playing with argsCanBeInterpretedByShell, but the behavior was worse with it set to true.

When we send the runInTerminal request, the path to test_file.py is part of the args array and looks like this (note the \t):

'/home/erikd/issues/debugpy/1671/test/[]`\\{:"",\t: ""\\}`\\{.\\}/test_file.py'

But when the launcher is started, the path it receives from sys.argv is this (no \t):

'/home/erikd/issues/debugpy/1671/test/[]`\\{:"",: ""\\}`\\{.\\}/test_file.py'

Yes, the quote function at https://github.com/microsoft/vscode/blob/393f929eff78295f740f2c801728d9238d8c6ec7/src/vs/workbench/contrib/debug/node/terminals.ts#L163 strips out the tab.
