[PATCH 0/3] restore cfgfile library tests

[PATCH 0/3] restore cfgfile library tests

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

Stephen Hemminger (3):
  buildtools: add helper to convert text file to header
  test: restore cfgfile tests
  test: remove unused resource API

[PATCH 2/3] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate before the test.

[PATCH 3/3] test: remove unused resource API

[Stephen Hemminger]

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v2 0/3] restore cfgfile library tests

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

v2 - use mkstemp instead of mktemps since the later does
     not exist on Windows (in mingw).

Stephen Hemminger (3):
  buildtools: add helper to convert text file to header
  test: restore cfgfile tests
  test: remove unused resource API

[PATCH v2 2/3] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate before the test.

[PATCH v2 3/3] test: remove unused resource API

[Stephen Hemminger]

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v3 0/3] restore lost tests for rte_cfgfile

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

v3 - change creation of temp file to support Windows

Stephen Hemminger (3):
  buildtools: add helper to convert text file to header
  test: remove unused resource API
  test: restore cfgfile tests

[PATCH v3 2/3] test: remove unused resource API

[Stephen Hemminger]

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v3 3/3] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate temporary file before the test.

[PATCH v4 0/3] restore lost cfgfile tests

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

v4 - add special treatment for temp directory in Windows
     the test obviously never ran before on Windows.

[PATCH v4 2/3] test: remove unused resource API

[Stephen Hemminger]

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v4 3/3] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate temporary file before the test.

[PATCH v5 0/4] restore unused cfgfile tests

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

v5 - rearrange tests input files
   - use unit_suite_runner
   - more Windows fixes

Stephen Hemminger (4):
  buildtools: add helper to convert text file to header
  test: remove unused resource API
  test: restore cfgfile tests
  test: rearrange test_cfgfiles cases

[PATCH v5 2/4] test: remove unused resource API

[Stephen Hemminger]

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v5 3/4] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate temporary file before the test.

The changes to app/test/meson.build are to handle auto-generated
files (resources) differently. Don't scan these files to look
for test input.

Using common unit test macro allows for simpler management
of more tests.

Small suggestion - I'd move this up to be patch 3, rather than patch 4,
which would save editing the list in the meson.build file to remove the
"etc/" prefix

Sure it would be logical to merge the two, just wanted the patches to
be smaller and easier to review

I actually think they are better separate, just switch the order.

[PATCH v6 0/4] test: restore cfgfile lib tests

[Stephen Hemminger]

The cfgfile tests did not get built since conversion to meson
and they used an awkward way to manage the test data.

This patchset converts the tests to use a helper to take
text file and make it into a C header. Then use the C header
to generate temporary files as needed.

v6 - rearrange patch order for easier review

Stephen Hemminger (4):
  buildtools: add helper to convert text file to header
  test: remove unused resource API
  test: rearrange test_cfgfiles cases
  test: restore cfgfile tests

[PATCH v6 2/4] test: remove unused resource API

This API was used only for cfgfile tests and was never built
after the conversion to meson. Will be replaced by simpler
method of doing cfgfile tests.

[PATCH v6 4/4] test: restore cfgfile tests

[Stephen Hemminger]

These tests were not built since the conversion to meson.
Instead of using embedded resource functions, put data in include
file and generate temporary file before the test.

The changes to app/test/meson.build are to handle auto-generated
files (resources) differently. Don't scan these files to look
for test input.

Using common unit test macro allows for simpler management
of more tests.
