tests: print the server error log in `test-url-download.t` There was a stray 500 error in CI, but no additional context to know what the issue was. https://foss.heptapod.net/octobus/mercurial-devel/-/jobs/163093 Differential Revision: https://phab.mercurial-scm.org/D9949

      # Oxidized Mercurial

      This project provides a Rust implementation of the Mercurial (`hg`)

      version control tool.

      Under the hood, the project uses

      [PyOxidizer](https://github.com/indygreg/PyOxidizer) to embed a Python

      interpreter in a binary built with Rust. At run-time, the Rust `fn main()`

      is called and Rust code handles initial process startup. An in-process

      Python interpreter is started (if needed) to provide additional

      functionality.

      # Building

      This project currently requires an unreleased version of PyOxidizer

      (0.7.0-pre). For best results, build the exact PyOxidizer commit

      as defined in the `pyoxidizer.bzl` file:

          $ git clone https://github.com/indygreg/PyOxidizer.git

          $ cd PyOxidizer

          $ git checkout <Git commit from pyoxidizer.bzl>

          $ cargo build --release

      Then build this Rust project using the built `pyoxidizer` executable::

          $ /path/to/pyoxidizer/target/release/pyoxidizer build

      If all goes according to plan, there should be an assembled application

      under `build/<arch>/debug/app/` with an `hg` executable:

          $ build/x86_64-unknown-linux-gnu/debug/app/hg version

          Mercurial Distributed SCM (version 5.3.1+433-f99cd77d53dc+20200331)

          (see https://mercurial-scm.org for more information)

      # Running Tests

      To run tests with a built `hg` executable, you can use the `--with-hg`

      argument to `run-tests.py`. But there's a wrinkle: many tests run custom

      Python scripts that need to `import` modules provided by Mercurial. Since

      these modules are embedded in the produced `hg` executable, a regular

      Python interpreter can't access them! To work around this, set `PYTHONPATH`

      to the Mercurial source directory. e.g.:

          $ cd /path/to/hg/src/tests

          $ PYTHONPATH=`pwd`/.. python3.7 run-tests.py \

              --with-hg `pwd`/../rust/hgcli/build/x86_64-unknown-linux-gnu/debug/app/hg
