Unit-tests of search results in XML format should work the same way with
a server that would inject a taskbar into HTML responses. This small
change actually validates that taskbar injection is disabled for XML
responses.
The file starts now to be too long.
- Move testing of the search html result in `test/server_html_search.cpp`
- Move common code used to launch server and so
in `test/server_testing_tools.h'
This is mainly code move with a small change:
Instead of setting the default PORT (8001) as a const int in the
`ServerTest` class, we now use SERVER_PORT.
SERVER_PORT must be defined before include `server_testing_tools.h`.
This allow several test to be run in parallele without trying to open
the same port.
If we keep a reference to a `Reader` it is better to (share) owning
the reference. Else the reader may be deleted after we create the searcher.
This is especially the case now we are creating the `Reader` at demand
and we don't store it in the library's cache.
We have to reuse the query the user give us to generate the
pagination links.
At search result rendering step we don't have access to the query object.
The best place to know which arguments are used to select books
(and so which arguments to keep in the pagination links) is when we
parse the query to select books.
Fix tests (pagination links) with book selector other than "books.id="
(pattern=jazz&books.query.lang=eng)
libzim's search is not thread safe (mainly because xapian is not).
So we must protect our search objects from multi thread calls.
The best way to do this is to associate a mutex to the `zim::Searcher`
and lock the searcher each time we access object derivated from the
searcher (search, results, iterator, ...)
When ConcurrentCache store a shared_ptr we may have shared_ptr in used
while the ConcurrentCache has drop it.
When we "recreate" a value to put in the cache, we don't want to recreate
it, but copying the shared_ptr in use.
To do so we use a (unlimited) store of weak_ptr (aka `WeakStore`)
Every created shared_ptr added to the cache has a weak_ptr ref also stored
in the WeakStore, and we check the WeakStore before creating the value.
The prefix will be used to parse a "query to select book" in different context.
For now we have only one context : selecting books for the catalog search.
But we will want to select books to do fulltext search on them
(will be done in later commit)
