[Bug] health_check.bat creates a stray empty directory (e.g. C:\Program) when the install path contains a space

Inizia da scripts/tools/windows/ops/health_check.bat, concentrandoti sulla routine :local_dirs_check e sulla relativa iterazione delle directory. Riproduci il problema con IoTDB installato in un percorso contenente spazi, quindi verifica che tools\windows\ops\health_check.bat -o local riporti ogni directory configurata come un unico percorso e non crei alcuna directory estranea.

Version

Reproduced on 2.0.8 and current master (identical code). Present since the tool was introduced (#12325); not addressed by #12435 (launch scripts) or #12450 (permission-detection logic).

Environment:

• OS: Windows (reproduces wherever the install path contains a space)
• IoTDB: 2.0.8 and master

Describe the bug and provide the minimal reproduce step

On Windows, if IoTDB is located under a path that contains a space (e.g. C:\Program Files\iotdb), the health-check tool's Installation Environment(Directory Access) check splits directory paths at the space. It:

1. creates a stray empty directory such as C:\Program, and
2. prints garbled results - e.g. "C:\Program" has write permission followed by "Files\...\ext\pipe" has write permission - instead of one line for the real directory.

To reproduce:

1. Unzip/install IoTDB into a path containing a space, e.g. C:\Program Files\iotdb (or C:\test dir\iotdb).
2. Run tools\windows\ops\health_check.bat -o local.
3. Observe a stray empty C:\Program directory, and split/garbled lines in the Directory Access section.

Any configured directory under the spaced install path triggers it; the ext/* dirs (pipe_lib_dir / udf_lib_dir / trigger_lib_dir) hit it by default because they resolve to %IOTDB_HOME%\ext\....

Affected file: scripts/tools/windows/ops/health_check.bat, routine :local_dirs_check.

Root cause:

:local_dirs_check joins the directory variables into spacedirs with spaces and iterates with for %%a in (%spacedirs%). The for ... in (set) form tokenizes on spaces (and ,/;), so a path containing a space is split into two
tokens. The inner for %%b/%%c loops already preserve spaces for the ;/, multi-dir separators via the "!var:;=" "!" technique, but the outer space-join defeats that. Separately, %%c (from for %%c in ("...")) still carries its
surrounding quotes, so mkdir "%%c" expands to mkdir ""C:\Program Files\..."" - a doubly-quoted path the argument parser re-splits.

What did you expect to see?

Each configured directory is checked as a single path; no stray directory is created; the output has one clean line per directory.

What did you see instead?

The tool splits directory paths at the space and creates a stray directory.

Anything else?

The docs recommend a space-free install path, but the tool shouldn't create stray directories or emit corrupt output when that guidance isn't met - especially since Windows users frequently install under C:\Program Files. A minimal fix is
available (see PR).
