Language code to human friendly name translation is now done with the
help of the ICU library. It works if the line
```
-include $(LANGSRCDIR)/resfiles.mk
```
in the file `source/data/Makefile.in` of the icu4c dependency is not
commented out. Currently, the said line is commented out (along with
some other include's) by the `icu4c_custom_data.patch` patch of the
`kiwix-build` tool.
This changes the output of `/catalog/search` as follows:
- Entire search query (rather than only the value of the `q` parameter)
is put in the <title> node.
- Search performed with an empty query presents itself as "All zims".
- The feed id remains stable for identical searches on the same
library.
/catalog/v2/entries is intended to play the combined role of
/catalog/root.xml and /catalog/search of the old OPDS API. Currently,
the latter role is not yet implemented.
Implementation note: instead of tweaking and reusing
`OPDSDumper::dumpOPDSFeed()`, the generation of the OPDS feed is done via `mustache`
and a new template `static/catalog_v2_entries.xml`.
Note: This commit somewhat relaxes validation of non variable
`<updated>` elements in the OPDS feed - the contents of any `<updated>`
element is replaced with the YYYY-MM-DDThh:mm:ssZ placeholder.
Returning status code 204 in case of an empty results doesn't show the
empty results page as described in #466. Reverting the changes in #396
fixes the issue.
Originally reported against case sensitivity of the Range header
(see issue #387), this fix applies to all request headers (since
according to RFC 7230 all header fields are case-insensitive, see
https://tools.ietf.org/html/rfc7230#section-3.2). However, a
corresponding unit-test was added only for the Range header.
On windows, `httplib.h` must be included before `windows.h`
We do not include directly `windows.h` in the test but it is included
indirectly by other headers.
Let's include httplib first.
libmicrohttpd handles HEAD requests by dropping the body of the response
(if any). Hence letting a HEAD request through into the code that
processes GET requests is safe.
Also added server unit-tests related to the handling of HEAD requests.
This change failed to build under the following platforms
due to an older version of libmicrohttpd missing support for
the MHD_DAEMON_INFO_BIND_PORT query:
- Linux (native_dyn)
- Linux (win32_dyn)
Added a new unit test 'test/server.cpp'. The pre-existing unit test
test/kiwixserve.cpp tests kiwixlib indirectly by running the kiwix-serve
executable which may be built with another version of the library.
Included with this commit is the cpp-httplib C++ HTTP/HTTPS library
(https://github.com/yhirose/cpp-httplib, v0.5.11).
The new file test/httplib.h was copied from
