[PATCH v2 00/10] Platform compatibility fixes

[Patrick Steinhardt <ps@pks.im>]

Hi,

this is the second version of my patch series that includes various
different platform compatibility fixes.

Changes compared to v1:

  - Provide a more in-depth explanation of the gitweb fix.

  - Fix up a stale comment in "lib-gitweb.sh".

  - Add a missing signoff.

Thanks!

Patrick

         t/lib-gitweb: test against the build version of gitweb
     
         When testing gitweb we set up the CGI script as "gitweb.perl", which is
    -    the source file of the build target "gitweb.cgi". This works alright as
    -    long as we run in-tree tests. But we're about to make out-of-tree tests
    -    a reality, and there things will break because "gitweb.perl" will not be
    -    found in the build directory.
    +    the source file of the build target "gitweb.cgi". This file doesn't have
    +    a patched shebang and still contains `++REPLACEMENT++` markers, but
    +    things generally work because we replace the configuration with our own
    +    test configuration.
     
    -    Fix this by using "gitweb.cgi" instead.
    +    But this only works as long as "$GIT_BUILD_DIR" actually points to the
    +    source tree, because "gitweb.cgi" and "gitweb.perl" happen to sit next
    +    to each other. This is not the case though once you have out-of-tree
    +    builds like with CMake, where the source and built versions live in
    +    different directories. Consequently, "$GIT_BUILD_DIR/gitweb/gitweb.perl"
    +    won't exist there.
    +
    +    While we could ask build systems with out-of-tree builds to instead set
    +    up GITWEB_TEST_INSTALLED, which allows us to override the location of
    +    the script, it goes against the spirit of this environment variable. We
    +    _don't_ want to test against an installed version, we want to use the
    +    version we have just built.
    +
    +    Fix this by using "gitweb.cgi" instead. This means that you cannot run
    +    test scripts without building that file, but in general we do expect
    +    developers to build stuff before they test it anyway.

         is the only instance where it has been failing.
