Bug 25032: Chomp stringified exception
If we catch a Koha::Exception-derived exception, the log is put in a
single line. If the code 'dies' then a newline character is appended to
the string. This patch chomps it so it displays in a single line.

To test:
1. Tweak Koha::REST::V1::Cities::list in the try block so it dies before
   render
2. Restart plack and try the original test plan
=> FAIL: Notice two lines are logged
3. Apply this patch
4. Repeat 2
=> SUCCESS: Only one line in the logs
5. Verify rendering a Koha::Exception works as well:
   Koha::Exceptions::Exception->throw("Nada!");

Bug 25032: Generic unhandled exception handling on API
This patch adds Koha::Logger as the default logger for the API, and
introduces a new helper plugin that takes care of handling the unhandled
exceptions. Basically, with this we would write something like this in
our controller methods:

    try {
        ...
    }
    catch {
        if ( know_exception ) {
            handle_known_exception($_);
        }

        $c->unhandled_exception($_);
    }

Without this, we end up adding more and more handling 'just in case'.

To test:
1. Edit the Koha/REST/V1/Cities.pm 'list' method adding
   die("Nada"); before the render step.
2. Restart plack and try the endpoint
=> FAIL: A generic error is displayed, and no traces of the original
problem are found on the logs.
3. Apply this patches, make sure your instance's log4perl has the
   introduced lines for API with the right path.
4. Repeat 2
=> SUCCESS: The message is still generic, but you see something is
logged in /var/log/koha/kohadev/api-error.log
5. Change die("Nada"); for a real exception like:

    use Koha::Exceptions;
    Koha::Exceptions::DuplicateObject->throw("Nada");
6. Repeat 2.
=> SUCCESS: The message is generic, but a meaningful text is added to
the logs.

Bug 25131: (QA follow-up) Move test for needs_install outside the plugin
This follow-up patch moves the check outside the register routine. The
Mojo plugin won't be loaded unless there's no need to install.

As the original tests rely on V1.pm to be able to load the plugin, they
are still valid, and they should still pass as there's no behaviour
change.

Bug 25131: Skip loading API plugins if Koha is not installed
This patch adds a check on Koha being actually installed to the
PluginRoutes Mojolicious plugin.

If Koha is not installed, plugin routes won't be tried to get installed.
This has the effect of making the webinstaller functional again (when
enable_plugins is set to 1).

To test:
1. Apply the regression tests patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/Koha/REST/Plugin/PluginRoutes.t
=> FAIL: Tests fail!
3. Apply this patch
4. Repeat 2
=> SUCCESS: Tests pass!
5. Reset your working branch
6. Delete your database (e.g. in koha-testing-docker):
   $ mysql -hdb -ppassword
   > DROP DATABASE koha_kohadev;
   > CREATE DATABASE koha_kohadev; \q
7. Set enable_plugins to 1 in koha-conf.xml
8. Restart all:
   $ service memcached restart
   $ koha-plack --restart kohadev
9. Open the staff interface
=> FAIL: Hangs, the logs show nasty errors (koha-plack-err)
10. Apply this patches
11. Restart all
12. Repeat 10
=> SUCCESS: The web installer shows up :-D

Bug 24700: Avoid validating REST API spec multiple times
This patch changes the spec loading so that it is fully loaded and merged with any plugin routes before validation. The individual parts are separately validated only if the resulting complete spec is invalid. Note: the OpenAPI plugin validates the spec given to it, so normally no manual validation is necessary.

Test plan:
1. prove -v t/db_dependent/Koha/REST/*
2. prove -v t/db_dependent/api/v1/*

Bug 20415: Remove UseKohaPlugins system preference
Owen Leonard 2018-03-16 10:47:47 UTC :
<<
I don't think the system preference adds any security. There are already multiple permissions required for working with plugins:

- Configure plugins
- Manage plugins ( install / uninstall )
- Use report plugins
- Use tool plugins

And even with those permissions your server must be configured to allow the use of plugins.
>>

Test plan :
1) Install kitchen sink plugin https://github.com/bywatersolutions/koha-plugin-kitchen-sink
2) Run misc/devel/install_plugins.pl
3) Set config enable_plugins=1
4) Check all parts of the plugin are working
5) Set config enable_plugins=0
6) Check all parts of the plugin are disabled

Bug 24830: Fix parse_prefetch recursion and +count cases
When a child of a prefetched element wasn't found on element's
prefetch_whitelist, no prefetch element was returned.. including element
it self. Now we return element's name if no child was found.

Also, embeded keys that ended with +count where taken literaly. Now we
search the correct key by stripping _count of embedded element if it was
declared as "is_count"

Bug 24528: Add a syntax to x-koha-embed to specify counts
This patch adds a + syntax to specify on the x-koha-embed header that we
want the count of a relation in the response. For example:

GET /patrons/1
x-koha-embed: checkouts+count

Would return a JSON representation of a Koha::Patron, with a new
attribute added: checkouts_count, which will be the result of calling
$patron->checkouts->count.

This is all done automatically in to_api. This patch makes parsing the
x-koha-embed header build the right structure for passing to the to_api
method.

Bug 24191: Add to_model param to _build_order_atom and dbic_merge_sorting
This patch adds a to_model parameter to dbic_merge_sorting so it is
passed when used (for example from objects.search). The to_model param
is passed along to the _build_order_atom method where it is finally
used.

In the process I wrote tests that reflected some problems in the current
code:
- Mojolicious automatically returns a scalar if a query parameter only
happens once on a request. The code expected an arrayref in every case.
- There's a design issue that forced me to use some hacky code in
_build_order_atom.

The first issue is dealth with, by using Scalar::Util::reftype as the
Perl docs recommend.

The second issue, I don't plan to clean it here, as there's ongoing work
on a Koha::Objects->search_from_api method that will obsolete this code
most probably (see bug 23893 for a better picture of where the mappings
will be living soon).

Tomas Cohen Arazi 3fedae85f2 Bug 21116: Add API routes through plugins
This patch adds plugins the capability of injecting new routes on the
API.

The plugins should provide the following methods to be considered valid API-generating plugins:

- 'api_routes': returning the 'path' component of the OpenAPI specification corresponding to the routes served by the plugin
- 'api_namespace': it should return a namespace to be used for grouping the endpoints provided by the plugin

otherwise, they will be just skipped.

All plugin-generated routes will be added the 'contrib' namespace, and
will end up placed inside /contrib/<namespace>, where <namespace> is what the 'api_namespace' returns.

A sample endpoint will be added to the Kitchen Sink plugin, and tests
are being written.

To test:
- Apply this patches
- Run:
  $ kshell
 k$ prove t/db_dependent/Koha/REST/Plugin/PluginRoutes.t
=> SUCCESS: Tests pass!
- Install the (latest) KitchenSink plugin
- Point your browser to the API like this:
  http://koha-intra.myDNSname.org:8081/api/v1/.html

implemented by the plugin has been merged!

Tomas Cohen Arazi 4bd62d0a8c Bug 19686: Add objects.search a 'to_model' param
This patch introduces a new parameter to the objects.search Mojo helper.
The idea behind this, is that if there's any attribute name mapping
between the DB objects and the API exposed ones, we should be able to
pass it to objects.search so the filtering query params are mapped
correctly for building the DBIC query, like this example:

  my $patrons_set = Koha::Patrons->new;
  my @patrons = $c->objects->search( $patrons_set,
                                     \&to_model
                                    )->as_list;
  # and probably
  @patrons = map {to_api($_)} @patrons;

The to_model function needs to avoid autovivification, to prevent
messing with the query parameters (undef params).

- Apply this patches
- Run:
  $ kshell
 k$ prove t/db_dependent/Koha/REST/Plugin/Objects.t

Tomas Cohen Arazi 8430a541af Bug 19370: (QA follow-up) Use OpenAPI's handling of pipe separated values
This patch makes the helper handling _order_by params expect a list of
values instead of a (to-be-splitted) string.

The idea is that the OpenAPI plugin will take care of splitting
pipe-delimited values if the spec is correctly defined.

Note: In the process I noticed + on the URL represents a space, so the
helper function is updated to handle both + and %2B as ascending.

To test:
- Run:
  $ kshell
 k$ prove t/Koha/REST/Plugin/Query.t
=> SUCCESS: Tests pass!
- Sign off :-D

Edit: Removed rebasing leftover making the tests fail.

Tomas Cohen Arazi 5a31321676 Bug 19370: Add helper function for order_by attribute generation
This patch introduces a helper function called 'dbic_merge_sorting'
to Koha::REST::Plugin::Query.

This simple function adds SQL::Abstract order_by attribute to the passed
$filter hashref, as explained in the POD.

It introduces a syntax for passing sorting params on the request to the REST api.
The proposed syntax has been found in the wild, and is pretty trivial to parse/work with:

    GET /api/v1/<endpoint>?order_by=+column_1|-column_2|column_3

As explained on the POD, + stands for 'asc' and - for 'desc'. If ommited, it defaults to the
DB engine default (usually asc).

To test:
- Apply this patches
- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
 k$ prove t/Koha/REST/Plugin/Query.t
=> SUCCESS: Tests pass! And they make sense! :-P
- Sign off :-D

Edit: renamed params to match DBIC terminology. My bad :-D (tcohen)

Tomas Cohen Arazi 54880b1a4e Bug 19278: Make the pagination plugin use RESTdefaultPageSize
This bug introduces a new syspref RESTdefaultPageSize that is used on
the Koha::REST::Plugin::Pagination plugin to default to a valid value
for the page size if the param is not present on the query.

This patch also considers the situation in which no 'page' param is
passed, and no header should be added.

To test:
- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
 k$ prove t/Koha/REST/Plugin/Pagination.t
=> FAIL: Tests fail because the plugin doesn't behave as the tests
expect.

 k$ prove t/Koha/REST/Plugin/Pagination.t

Tomas Cohen Arazi cea8b9c7c5 Bug 19234: Add query parameters handling helpers
This patch introduces a Mojolicious plugin to be used on the REST api.
It adds a helper method:

generate_dbic_query
===================

When used, it generates what's needed to perform a search on
DBIC/Koha::Objects like this:

    my $params  = $c->validation->output;
    my ($filtered_params, $reserved_params) = $c->extract_reserved_params($params);

    my $filter = do_smth($filtered_params, $reserved_params);
    my $attributes = do_smth_reserved($reserved_params);

    my $patrons = Koha::Patrons->search( $filter, $attributes );

It introduces reserved param names:
- _match
- _order_by
- _page
- _per_page

They are reserved for later usage (pagination, matching algorithm on building DB queries)

All the plugin's behaviour is tested.

To test:
- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
 k$ prove t/Koha/REST/Plugin/Query.t
=> SUCCESS: Tests pass!
- Sign off :-D

Tomas Cohen Arazi 26f3ca8d88 Bug 19196: Add Koha::REST::Plugin::Pagination
This patch introduces a Mojolicious plugin to be used on the REST api.
It adds a helper method:

add_pagination_headers
======================

When used, it adds a _Link_ header to the reponse with the calculated
values for pagination, and X-Total-Count containing the total results
like this:

    my $params  = $c->validation->output;
    my $patrons = Koha::Patrons->search;
    my $count   = $patrons->count;

    $c->add_pagination_headers({
            total  => $count,
            params => $params )};

- Run:
  $ sudo koha-shell kohadev
 k$ cd kohaclone
