Subject: [PATCH 1/9] Run the Python variant of web-app-cosmosdb-nosql-api in
 the samples CI

run-samples.sh registered 26 of the 27 sample variants that ship scripts; the Python variant of web-app-cosmosdb-nosql-api was the one missing, so CI only ever ran its .NET counterpart.
It is registered next to the .NET entry with the same deploy, validate and call steps, and, like it, is not added to ARM64_SAMPLE_DIRS.

Subject: [PATCH 2/9] Run the scripts from Git Bash and MSYS2 with
 MSYS_NO_PATHCONV=1

Git Bash and MSYS2 shells rewrite every argument that looks like an absolute POSIX path before starting a Windows program, so Azure values such as the Cosmos DB partition key path /username, resource IDs and the Front Door origin path reached az as Windows paths (SMF-963).
The README now asks Windows users of these shells to export MSYS_NO_PATHCONV=1, which turns the rewriting off, and explains why.
With the rewriting off, the local files the scripts hand to Windows programs need their Windows form: the temporary files read by curl and jq, the Python checks of the Event Hubs samples, the API Management definition and policy, the downloaded blob and the QR code.
A native_path helper in each of these scripts returns that form through cygpath when it exists and the path unchanged otherwise, so Linux, macOS and WSL behave exactly as before.

 ```
 Or by installing and using `dos2unix`.
 
+### Windows: Git Bash and MSYS2
+
+The scripts are written for Bash and run unchanged on Linux, macOS and WSL.
+They also run on Windows from Git Bash or from an MSYS2 shell (for example MINGW64 or UCRT64), provided you first turn off the automatic path conversion of these shells:
+
+```bash
+export MSYS_NO_PATHCONV=1
+```
+
+When Git Bash or an MSYS2 shell starts a Windows program such as the Azure CLI, it rewrites every argument that looks like an absolute POSIX path into a Windows path.
+Azure values that only look like paths are rewritten too, and the commands that receive them fail:
+
+- `--partition-key-path /username` reaches `az` as `C:/Program Files/Git/username`, so creating the Cosmos DB container fails with an invalid partition key path error.
+- Resource IDs such as `/subscriptions/<subscription-id>/resourceGroups/...`, passed to `--scope`, `--ids` and similar options, become paths under the shell's installation folder, for example `C:/Program Files/Git/subscriptions/...`.
+- Paths such as the Front Door `--origin-path /api` are rewritten the same way.
+
+With `MSYS_NO_PATHCONV=1` set, these values reach the Azure CLI exactly as written.
+The scripts convert the paths of the local files they hand to Windows programs, such as the temporary files read by `curl` and `jq`, with `cygpath` when it is available, so they keep working with the variable set.
+On Linux and macOS `cygpath` does not exist, and the paths are left unchanged.
+
+Tips:
+
+- To set the variable in every new Git Bash window, add `export MSYS_NO_PATHCONV=1` to `~/.bash_profile`, or to `~/.bashrc` if your `.bash_profile` sources it.
+- `echo $MSYSTEM` prints a value such as `MINGW64` only in these shells.
+- Any value turns the conversion off, `0` included; run `unset MSYS_NO_PATHCONV` to turn it back on.
+- WSL runs Linux and needs no variable.
+- When you write a script that passes a local file to `az`, `curl`, `jq`, `python` or `docker`, convert its path with the `native_path` helper the existing scripts define.
+
 ## Configuration

Subject: [PATCH 3/9] Hand zip a Windows path for the archives the Event Hubs
 scripts build

The Event Hubs and Event Hubs with Event Grid deployments write their function and dashboard archives to an absolute path under the scripts folder.
Git Bash ships no zip, and a zip.exe built for Windows cannot open a /c/... path once MSYS_NO_PATHCONV=1 is set, so the archive path now goes through native_path as well; a zip from MSYS2 accepts the C:/... form too.

Subject: [PATCH 4/9] Remove the empty file whose name breaks checkouts on
 Windows

Git for Windows refuses to check out a path whose last component ends with a period, so a clone of this repository on Windows stops with "error: invalid path 'samples/web-app-cosmosdb-nosql-api/python/scripts/...'" and leaves no working tree.
The file named "..." is empty, nothing references it, and it arrived by accident in 0f07d42.

Subject: [PATCH 5/9] Discard curl's responses through the NUL device in Git
 Bash and MSYS2

With MSYS_NO_PATHCONV=1 these shells no longer turn a /dev/null argument into nul for Windows programs, so a Windows curl given -o /dev/null cannot open its output and exits with code 23 as soon as a response has a body.
The MySQL readiness loops would then read HTTP_CODE as 200000, the status followed by their || echo "000" fallback, and never finish.
A null_device helper returns NUL for a Windows curl in these shells and /dev/null everywhere else, MSYS2's own curl included, and the 23 curl calls that discard a body in 11 scripts use it.
The README says so, and tells script authors to do the same.

Subject: [PATCH 6/9] Run Maven with the path conversion back on in the Service
 Bus sample

Maven's mvn launcher is a shell script that hands its own paths, such as its classpath, to Java, a Windows program on Windows, and relies on Git Bash and MSYS2 converting them.
With MSYS_NO_PATHCONV=1 Java received the POSIX paths and stopped with "Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher", as the Windows job showed.
The three deploy scripts of the Service Bus sample run mvn in a subshell that unsets the variable, and the README tells script authors to do the same for such launchers.

 - WSL runs Linux and needs no variable.
 - When you write a script that passes a local file to `az`, `curl`, `jq`, `python`, `docker` or `zip`, convert its path with the `native_path` helper the existing scripts define; Git Bash ships no `zip`, and a `zip.exe` built for Windows needs the converted path too.
 - To discard what a Windows program writes to a file, such as `curl -o`, pass it `"$(null_device)"` rather than `/dev/null`, as the existing scripts do. Shell redirections such as `> /dev/null` need no change.
+- A launcher written as a shell script that hands its own paths to a Windows program, such as Maven's `mvn`, needs the conversion: run it as `(unset MSYS_NO_PATHCONV; mvn ...)`, as the Service Bus sample does. Setting the variable to an empty value is not enough, because any value turns the conversion off.

Subject: [PATCH 7/9] Tell Git Bash and MSYS2 users to drop the carriage
 returns of Windows programs

Windows programs such as the Azure CLI and jq end every line with a carriage return, which Bash keeps in $(...) and read, so a name or an ID read from az --output tsv carries a trailing \r.
In the Windows CI run, the App Configuration sample's private endpoint failed twice with ResourceNotFound for a key vault that existed, its name ending in that \r.
MSYS2's bash, which Git Bash ships, drops carriage returns from command substitution and read when its igncr option is on, and an exported SHELLOPTS passes the option to the scripts, so the README asks for set -o igncr and export SHELLOPTS next to MSYS_NO_PATHCONV=1.

+- WSL runs Linux and needs none of these settings.
 - When you write a script that passes a local file to `az`, `curl`, `jq`, `python`, `docker` or `zip`, convert its path with the `native_path` helper the existing scripts define; Git Bash ships no `zip`, and a `zip.exe` built for Windows needs the converted path too.
 - To discard what a Windows program writes to a file, such as `curl -o`, pass it `"$(null_device)"` rather than `/dev/null`, as the existing scripts do. Shell redirections such as `> /dev/null` need no change.
 - A launcher written as a shell script that hands its own paths to a Windows program, such as Maven's `mvn`, needs the conversion: run it as `(unset MSYS_NO_PATHCONV; mvn ...)`, as the Service Bus sample does. Setting the variable to an empty value is not enough, because any value turns the conversion off.

Subject: [PATCH 8/9] Strip the carriage return of the Azure CLI from the
 arrays mapfile fills

On Windows the Azure CLI ends every line with a carriage return, and bash's igncr option drops it from $(...) and read but not from mapfile.
The App Configuration samples read several fields at once with mapfile, so in the Windows CI the key vault ID kept its \r and the private endpoint failed with ResourceNotFound, and the AKS sample read the cluster's OIDC and workload identity flags as "true\r".
Every mapfile that reads az output, in those samples and in the AKS cluster scripts, now reads it through tr -d '\r', which changes nothing on Linux and macOS, and the README says igncr does not cover mapfile.

Subject: [PATCH 9/9] Skip the SQL Database certificate check where the
 container IP is unreachable

call-web-app.sh compares the certificate the web app loaded from Key Vault with the one it serves on port 8443, and reaches that port through the container's IP address.
The host can reach that address only when Docker runs natively on Linux; with Docker Desktop on Windows and macOS, and in the Windows CI, the .NET script timed out and failed a deployment that worked.
Both scripts now record whether the earlier call through the container IP succeeded, and when it did not, they say so and skip the certificate check. On Linux the check runs as before, the .NET one failing when HTTPS on port 8443 is broken.
