Some reg tests and their dependencies have been renamed. They may be
referenced by the .vtc files. So, this patch modifies also the references
to these dependencies.
This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more
mnemonic and human readable. It is uses as a filter to run the reg tests scripts
where a commented #REGTEST_TYPE may be defined to designate their types.
Running the following command:
$ REGTESTS_TYPES=slow,default
will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'.
Note that 'default' is also the default value of REGTEST_TYPE when not specified
dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified
there is no filter at all. All the tests are run.
This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files,
'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.
RFC 7232 section 2.3.3 states:
> Note: Content codings are a property of the representation data,
> so a strong entity-tag for a content-encoded representation has to
> be distinct from the entity tag of an unencoded representation to
> prevent potential conflicts during cache updates and range
> requests. In contrast, transfer codings (Section 4 of [RFC7230])
> apply only during message transfer and do not result in distinct
> entity-tags.
Thus a strong ETag must be changed when compressing. Usually this is done
by converting it into a weak ETag, which represents a semantically, but not
byte-by-byte identical response. A conversion to a weak ETag still allows
If-None-Match to work.
This should be backported to 1.9 and might be backported to every supported
branch with compression.
