This was done in preparation for removing the `bookName` and `bookTitle`
parameters from `Response::build_404()`, but since the new function
could already be put to some use in this commit that was done too.
Before this change the meaning of test data in the ServerTest.404WithBodyTesting
unit test entirely depended on the number of entries:
- 2 entries: url, expected body
- 4 entries: url, book name, book title and expected body
This was fragile and non scalable (if other combinations of expected
response data are needed).
This commit defines a mini-DSL taking advantage of operator overloading
that allows to define test data in a robust way with the help of the compiler.
Some code in `TestContentIn404HtmlResponse` is obsoleted by this change
however it is not removed in this commit so that the change is easier to
understand. That will be done next.
Previously, the seachURL was not encoded.
This resulted in an XSS vulnerability, a concept of proof is:
start kiwix-serve
visit - http://192.168.18.1:8081/"><svg onload="alert(1)">
This would display an alert message.
This encodes the searchURL before passing it to searchSuggestionHtml
We create a cache for SuggestionSearcher very similar to that of FT
searcher. User can specify a custom cache size using the environment
variable SUGGESTION_SEARCHER_CACHE_SIZE. It has a default value of 10%
of the number of books in the library.
We use the new cache template to implement two kind of cache.
1: The Searcher cache is more general in terms of its usage. A Searcher
can be used for multiple searches without much change to itself. We
try to retrieve the searcher and perform searches using it whenever
possible, and if not we put a searcher into the cache. User can
specify a custom cache length by manipulating the environment
variable SEARCHER_CACHE_SIZE. It's default value is 10% of all the
books available.
2: The search cache is much more restricted in terms of usage. It's main
purpose is to avoid re-searching on the searcher during page changes
to generate SearchResultSet of various ranges. User can specify a
custom cache length using the environment variable SEARCH_CACHE_SIZE
with a default value of 2;
Adds a std::map<std::string, std::string> with display names for language codes not given by libicu
Fault language codes are taken from library.kiwix.org
The `ServerTest.RandomOnNonExistentBook` unit test was replaced with a
more general one testing multiple 404 scenarios where the content of the
body is checked too.
This test was introduced with the purpose of testing the error message
in the 404 page returned by /random for a non-existent book. The actual
expected output currently present in this new unit-test is too much for
that purpose and may become a maintenance burden if more tests of that
kind are added.
