📝 Walkthrough

Walkthrough

Adds configurable installation and upgrade paths to deploy/auto-install.sh. The script defaults to /opt/openwisp, accepts optional paths, normalizes them, and derives related environment, backup, installation, and log paths. Path quoting now covers installation, upgrade, Docker, Git, configuration, and logging operations. The quickstart documents these options, and tests cover argument parsing.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 72510

Custom install and upgrade paths can currently allow unsafe or incomplete upgrades, silently mishandle extra arguments, report invalid paths only after later failures, and direct users to the wrong default log location. The PR should not merge until these issues are fixed or explicitly accepted by the owner.

Full details: Description check

Explanation

The description includes the checklist, issue reference, change summary, and screenshot section. The anti-AI policy checklist item is omitted, and the screenshot section has no content, but the required change information is otherwise complete.

Full details: Linked Issues check

Explanation

The pull request implements the main requirements in issue #514 by accepting custom paths for --install and --upgrade and documenting the behavior. However, the upgrade flow can silently continue without an existing environment backup and may finish with an empty .env file, which makes custom-path upgrades unsafe for some invalid or incomplete paths.

Resolution

Validate that the environment backup source exists before upgrading. Fail with a clear error when the specified path does not contain the expected environment file. Also reject unknown or extra arguments with an error and exit status 1 instead of silently selecting help mode.

Full details: Out of Scope Changes check

Explanation

The changes are within scope for issue #514. The script updates, documentation, and argument-parsing tests directly support configurable installation and upgrade paths. No unrelated changes are identified.

Full details: Ui Changes, Regression Test, Docs

Explanation

The check passes. The pull request changes a command-line deployment script and does not change a web UI, so screenshots are not required. It adds TestLocalUtils.test_auto_install_argument_parsing, which covers custom install and upgrade paths, spaces in paths, and the default path. It documents the default path and custom --install and --upgrade usage in docs/user/quickstart.rst.

In `@deploy/auto-install.sh`:
- Around line 72-73: The problem is that the curl and sh invocations use single
quotes around '${USER_INSTALL_PATH}/get-docker.sh' which prevents shell variable
expansion; update the two commands that reference
${USER_INSTALL_PATH}/get-docker.sh (the curl line and the sh line) to allow
expansion by removing the single quotes or using double quotes so the variable
expands at runtime and the script is saved and executed from the intended path.
- Around line 313-321: The issue is the unconditional inner "shift" inside the
case branch handling "-i | --install | -u | --upgrade" which consumes the next
token even when no path was provided or when that token is another flag; update
the case handling around USER_INSTALL_PATH and the shifts so that you only call
"shift" to consume the optional path when a path was actually set (i.e., when [[
-n "$2" ]] is true), leaving the outer "shift" to consume the option flag
itself; locate the case branch that sets USER_INSTALL_PATH and adjust control
flow to avoid shifting away a next flag or shifting past available args.
- Around line 313-327: The script accepts arbitrary USER_INSTALL_PATH and then
builds INSTALL_PATH, LOG_FILE, ENV_USER, ENV_BACKUP but uses those variables
unquoted; fix by wrapping every expansion of $USER_INSTALL_PATH, $INSTALL_PATH,
$LOG_FILE, $ENV_USER and $ENV_BACKUP in double quotes throughout the script
(e.g., change occurrences used in mv, rm -rf, cd, make -C, and any other
commands to use "$INSTALL_PATH", "$ENV_BACKUP", "$ENV_USER", "$LOG_FILE",
"$USER_INSTALL_PATH") so paths with spaces or glob characters are not split or
expanded.

In `@deploy/auto-install.sh`:
- Around line 299-301: The help text prints option labels with a backslash
(e.g., "-i\--install", "-u\--upgrade", "-h\--help") which can render oddly;
update the strings emitted by the echo statements to use a conventional
separator such as "/" or ", " between short and long options (for example
"-i/--install" and "-u/--upgrade") so the usage lines are clear and display
correctly in the help output.
- Line 202: The command substitution for TAG in the make invocation is unquoted;
update the make call (the line invoking make start with TAG=$(cat
"$INSTALL_PATH/VERSION") -C "$INSTALL_PATH/" &>>"$LOG_FILE") to quote the
substitution so the TAG assignment becomes TAG="$(cat "$INSTALL_PATH/VERSION")"
to preserve whitespace and glob characters when reading the VERSION file; keep
the surrounding variables (INSTALL_PATH, LOG_FILE) and redirection as-is.
- Around line 195-198: The current for loop that iterates over command
substitution of grep | cut can break on config names with whitespace; replace it
with a while read loop that reads each config line safely using IFS= and read
-r, feeding the output of grep '=' "$ENV_BACKUP" | cut -f1 -d'=' via process
substitution or a pipe, then call get_env "$config" "$ENV_BACKUP" and set_env
"$config" "$value" inside the loop; target the block using the variables/symbols
ENV_BACKUP, get_env, set_env and the existing loop to implement this change.
- Line 179: The make invocation uses unquoted command substitution for TAG which
can break if the VERSION file contains whitespace; update the make command so
the TAG assignment quotes the substitution (e.g., change TAG=$(cat
"$INSTALL_PATH/VERSION") to TAG="$(cat "$INSTALL_PATH/VERSION")") in the line
invoking make start -C "$INSTALL_PATH/" &>>"$LOG_FILE" to prevent word
splitting.
- Around line 190-192: The upgrade path block should get the same defensive
handling as setup_docker_openwisp: validate INSTALL_PATH is non-empty and
writable, use a safe cd invocation that checks its exit status (so replace the
bare cd "$INSTALL_PATH" with a guarded cd and then call check_status if cd
fails), ensure all expansions use quotes (e.g. "$INSTALL_PATH" and "$LOG_FILE"),
redirect both stdout/stderr to the log consistently, and ensure writing VERSION
uses a safe write (create the directory if missing and handle failures) while
keeping the existing check_status/error handling for openwisp_version; update
the upgrade-path code that touches INSTALL_PATH, LOG_FILE, check_status, and
openwisp_version to mirror the fixes in setup_docker_openwisp.
- Around line 126-128: The script currently runs cd "$INSTALL_PATH"
&>>"$LOG_FILE" but doesn't stop if cd fails and later writes an unquoted
$openwisp_version into VERSION; update the sequence so the cd is checked
immediately (use the cd command's exit status and call check_status on failure
before proceeding) and ensure when writing the version you quote the variable
(write "$openwisp_version" to "$INSTALL_PATH/VERSION"); keep using INSTALL_PATH,
LOG_FILE, check_status and openwisp_version identifiers to locate and change the
lines.

In `@docs/user/quickstart.rst`:
- Around line 75-78: The inline comment-style notation in the example command
"sudo bash auto-install.sh  # [--install install-path]" can cause users to copy
the "#" accidentally; update the docs to present the optional flag separately
and clearly reference the "--install install-path" flag (e.g., show the command
without the "#" and add a following explanatory line or a separate example
demonstrating use of the "--install" flag), ensuring the code block only
contains the exact command to run and the explanatory text describes the
optional flag.
- Line 94: Replace the inline comment in the code block that reads "sudo bash
auto-install.sh --upgrade  # [install-path]" with explicit, separate upgrade
examples: one showing the default upgrade invocation using the auto-install.sh
script with the --upgrade flag, and a second showing how to pass an explicit
install path using the --install-path option (e.g., auto-install.sh --upgrade
--install-path /your/install/path); update the documented line referencing the
script name auto-install.sh and flags --upgrade and --install-path so readers
see concrete example usages instead of an inline comment.

Learning: In the docker-openwisp Makefile, `include .env` is intentionally mandatory (not `-include .env`) because the .env file contains critical configurations that must be present for safe operation. Silent failures with empty values would be more dangerous than failing explicitly when the file is missing.

14-23: LGTM!

Formatting-only changes to the data_ciphers array indentation. No functional impact.

deploy/auto-install.sh (4)

4-4: LGTM!

Default USER_INSTALL_PATH is properly initialized before argument parsing, allowing it to be overridden when -i/-u flags provide a custom path.


72-73: LGTM!

Docker bootstrap paths are now properly quoted, resolving the variable expansion issue from the previous review.


82-84: LGTM!

Path variables are properly quoted, supporting paths with spaces or special characters.


313-328: LGTM!

The argument parsing logic correctly:

  1. Only consumes the path argument when it exists and isn't another flag ("$2" != -*)
  2. Only shifts when a path is actually consumed
  3. Derives dependent exports (INSTALL_PATH, LOG_FILE, etc.) after parsing completes

This resolves the issues raised in previous reviews.

@nemesifier: Here are the real issues I found in deploy/auto-install.sh:


1. No existence check on ENV_BACKUP during upgrade — silent data loss

In upgrade_docker_openwisp, the restore loop runs unconditionally:

for config in $(grep '=' "$ENV_BACKUP" | cut -f1 -d'='); do
    value=$(get_env "$config" "$ENV_BACKUP")
    set_env "$config" "$value"
done

ENV_BACKUP is only created by download_docker_openwisp if $INSTALL_PATH/.env already exists:

if [[ -f "$INSTALL_PATH/.env" ]]; then
    mv "$INSTALL_PATH/.env" "$ENV_BACKUP" ...
fi

With the new custom-path feature, a user who passes a wrong or fresh path to --upgrade will have no $INSTALL_PATH/.env, so ENV_BACKUP is never created. grep on the non-existent file then silently fails, the restore loop runs zero iterations, and the upgrade finishes with a blank .env — no error, no warning.

A guard should be added:

upgrade_docker_openwisp() {
    ...
    if [[ ! -f "$ENV_BACKUP" ]]; then
        error_msg "No backup config found at $ENV_BACKUP. Is $USER_INSTALL_PATH the correct install path?"
    fi
    ...
}

2. The *) action='help' catch-all silently hijacks the action

The argument-parsing loop has two separate case blocks on $1. The first one contains:

*) action='help' ;;

Any extra/unrecognized token that reaches this block (e.g. a stray argument after the path) silently resets action to 'help', discarding the previously parsed install/upgrade intent with no error message. For example:

sudo bash auto-install.sh --install /opt/custom typo
# action ends up as 'help', not 'install'

The catch-all should emit an error instead:

*)
    echo -e "${RED}Unknown argument: $1${NON}"
    init_help
    exit 1
    ;;

79-95: ⚠️ Potential issue | 🟠 Major

Fail fast when git clone fails.

download_docker_openwisp() logs the git clone, but never checks its exit status. Both callers then validate only cd, which can still succeed on a partially created target directory after a failed clone, so the script continues with a broken checkout and reports the wrong step as successful.

🛠️ Proposed fix
 	git clone "$GIT_PATH" "$INSTALL_PATH" --depth 1 --branch "$GIT_BRANCH" &>>"$LOG_FILE"
+	check_status $? "docker-openwisp download failed."

- Around line 18-25: The set_env function currently uses eval to construct an
awk command which risks shell injection; change it to call awk directly without
eval and pass the key, value and target line number via awk -v (e.g., use awk -i
inplace -v k="$1" -v v="$2" -v ln="$line_number" 'NR==ln {$0 = k"="v}1'
"$INSTALL_PATH/.env"), ensure you still handle the append case when the key is
missing and keep using INSTALL_PATH, set_env, line_number and the .env file
variables.

In `@docs/user/quickstart.rst`:
- Around line 101-102: The doc example uses "--upgrade --install
/path/to/install" which is parsed by deploy/auto-install.sh as the install
action; update the quickstart example to use the actual upgrade flag syntax the
script expects (e.g. replace the example with the correct form such as
"--upgrade --install-path /path/to/install" or whatever flag name is implemented
in deploy/auto-install.sh), and ensure the flag name in docs matches the unique
symbol used in the script (the install/upgrade flag parsing logic in
deploy/auto-install.sh) so the command triggers the upgrade flow rather than
switching back to install mode.

status if clone fails, so callers relying on cd won't continue on a broken
checkout—refer to the function name download_docker_openwisp and ensure the git
clone invocation is followed by an if/conditional that handles failure and
terminates the script.

Timestamp: 2026-02-17T17:08:12.144Z
Learning: In docker-openwisp, OPENWISP_VERSION=edge is intentionally set as the default in .env to maintain consistency with the existing TAG=edge default in the Makefile. Production users are expected to override OPENWISP_VERSION in their .env file to pin to a specific stable release tag.

File: Makefile:4-5
Timestamp: 2026-02-17T16:59:43.808Z
Learning: In the docker-openwisp Makefile, `include .env` is intentionally mandatory (not `-include .env`) because the .env file contains critical configurations that must be present for safe operation. Silent failures with empty values would be more dangerous than failing explicitly when the file is missing.

Learning: In docker-openwisp, the OpenVPN container (images/common/init_command.sh) exits silently with exit code 0 when VPN_DOMAIN environment variable is not set. Combined with restart policy "on-failure" in docker-compose.yml, this prevents the container from restarting when VPN is disabled.

1. No existence check on ENV_BACKUP during upgrade — silent data loss
I think #568 should be dealing with that, do you have a way to check?

2. The *) action='help' catch-all silently hijacks the action
If not specific to this PR, I'd create a new issue.

redirection to check both operations, stop when either fails, and display a
clear user-facing error before exiting; do not continue with installation when
the custom path cannot be initialized.
- Around line 356-364: Update the argument parsing case for install/upgrade
options so unknown or extra tokens are rejected instead of being left for the
catch-all help path: report an unknown-argument error, display help, and exit
with status 1. Add focused regression cases in the existing tests to cover both
unknown arguments and extra arguments after an optional install path.
- Around line 232-240: Update the upgrade flow around download_docker_openwisp
to abort unless "$INSTALL_PATH/.env" exists before replacement, and validate
that "$ENV_BACKUP" was created after the download before reading it in the
configuration-restore loop. Preserve the existing failure handling and add a
focused regression test covering an upgrade with no .env file.

In `@docs/user/quickstart.rst`:
- Around line 78-84: Update the quickstart log-viewing guidance to explain that
autoinstall.log is stored under the selected installation path; instruct users
to replace /opt/openwisp with their custom --install path, or provide an
equivalent custom-path example.

Apply the same fix in `@deploy/auto-install.sh` around lines 367 - 370: The script
now derives LOG_FILE from USER_INSTALL_PATH, so the documentation must reflect
that behavior.

Abort upgrades when the previous environment is missing.

download_docker_openwisp creates ENV_BACKUP only when "$INSTALL_PATH/.env" exists in Lines 103-105. The upgrade path does not validate that file before replacement. It then reads ENV_BACKUP without checking whether the backup exists. With an incorrect custom path, the script can continue with an incomplete .env and start Docker without the previous credentials and settings.

Require "$INSTALL_PATH/.env" before the upgrade. After the download, verify that "$ENV_BACKUP" exists before restoring configuration. Add a regression test for an upgrade path without .env.

🐛 Proposed fix
 upgrade_docker_openwisp() {
 	echo -e ${GRN}"\nOpenWISP Configuration:"${NON}
 	get_version_from_user
 	echo ""

+	if [[ ! -f "$INSTALL_PATH/.env" ]]; then
+		error_msg "Cannot upgrade: $INSTALL_PATH/.env does not exist."
+	fi
+
 	download_docker_openwisp "$openwisp_version"

+	if [[ ! -f "$ENV_BACKUP" ]]; then
+		error_msg "Upgrade environment backup was not created."
+	fi

 	cd "$INSTALL_PATH" &>>"$LOG_FILE"

This behavior predates custom installation paths and is separate from the requested path-selection feature. Keeping this PR focused.

@nemesifier, understood. The missing upgrade environment validation predates this change. Keeping PR #515 focused on custom path selection is reasonable.

Would you like me to open a separate GitHub issue for the upgrade-flow validation?
