search: make "repository:" condition work case-insensitively as expected

Before this revision, "repository:" condition at searching for "Commit
messages" never shows revisions in a repository, of which name uses
upper case letter.

Using ID for "repository" of CHGSETS_SCHEMA preserves case of
repository name at indexing. On the other hand, search condition
itself is forcibly lowered before parsing.

- files in repository "FOO" is indexed as "FOO" in "repository" field
- "repository:FOO" condition is treated as "repository:foo:

Then, indexing search itself is executed case-sensitively. Therefore,
"repository:FOO" condition never show revisions in repository "FOO".

But just making "repository" of CHGSETS_SCHEMA case-insensitive isn't
reasonable enough, because it breaks assumptions below, if there is
case-insensitive name collision between repositories, even though
Kallithea itself can manage such repositories at same time.

- combination of "raw_id" (= revision hash ID) and "repository" is
unique between all known revisions under Kallithea

CHGSETS_SCHEMA assumes this.

This unique-ness is required by Whoosh library to determine
whether index table should be updated or not for that repository.

- searching in a repository shows only revisions in that repository

Before this revision, this filtering is achieve by "repository:"
condition with case-preserved repository name from requested URL.

To make "repository:" search condition work case-insensitively as
expected (without any violation of assumptions above), this revision
does:

- make "repository" of CHGSETS_SCHEMA case-insensitive by
"analyzer=ICASEIDANALYZER"

- introduce "repository_rawname" into SCHEMA and CHGSETS_SCHEMA, to
ensure assumptions described above, by preserving case of
repository name

"repository_rawname" of SCHEMA uses not ID but TEXT, because the
former disable "positions" feature, which is required for
highlight-ing file content (see previous revision for detail).

This revision requires full re-building index tables, because indexing
schemas are changed.
.. _troubleshooting:

===============
Troubleshooting
===============

:Q: **Missing static files?**
:A: Make sure either to set the ``static_files = true`` in the .ini file or
   double check the root path for your http setup. It should point to
   for example:
   ``/home/my-virtual-python/lib/python2.7/site-packages/kallithea/public``

|

:Q: **Can't install celery/rabbitmq?**
:A: Don't worry. Kallithea works without them, too. No extra setup is required.
    Try out the great Celery docs for further help.

|

:Q: **Long lasting push timeouts?**
:A: Make sure you set a longer timeout in your proxy/fcgi settings. Timeouts
    are caused by the http server and not Kallithea.

|

:Q: **Large pushes timeouts?**
:A: Make sure you set a proper ``max_body_size`` for the http server. Very often
    Apache, Nginx, or other http servers kill the connection due to to large
    body.

|

:Q: **Apache doesn't pass basicAuth on pull/push?**
:A: Make sure you added ``WSGIPassAuthorization true``.

|

:Q: **Git fails on push/pull?**
:A: Make sure you're using a WSGI http server that can handle chunked encoding
    such as ``waitress`` or ``gunicorn``.

|

:Q: **How can I use hooks in Kallithea?**
:A: It's easy if they are Python hooks: just use advanced link in
    hooks section in Admin panel, that works only for Mercurial. If
    you want to use Git hooks, just install th proper one in the repository,
    e.g., create a file `/gitrepo/hooks/pre-receive`. You can also use
    Kallithea-extensions to connect to callback hooks, for both Git
    and Mercurial.

|

:Q: **Kallithea is slow for me, how can I make it faster?**
:A: See the :ref:`performance` section.

|

:Q: **UnicodeDecodeError on Apache mod_wsgi**
:A: Please read: https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/modwsgi/#if-you-get-a-unicodeencodeerror.

|

:Q: **Requests hanging on Windows**
:A: Please try out with disabled Antivirus software, there are some known problems with Eset Antivirus. Make sure
    you have installed the latest Windows patches (especially KB2789397).
