[ldapfeed] fix connection leak (closes #2532528)

[zmq] add an introductive docstring on ZMQComm

[server config] on quick start, system source is still activated. Closes #2535714

[web] use `inline` `Content-Disposition` by default (closes #2535734) since known time we have been serving static file with a `filename` parameter on the `Content-Disposition` header. But since d74addac92bb we explicitly serve file as attachment if a filename is provided. However this is valid to have `inline` disposition and `filename` parameter. This changeset revert this part of d74addac92bb, going back to `inlined` by default. `IDownloadable` code explicitly request `attachment` content to preserve expected behavior.

[web] allow configuration of the Content-disposition value The `set_content_type` function now takes and optional `disposition` parameter to control the value of this HTTP header. Use of `Content-disposition: inline` with a filename parameter are valid, so the presence of filename does not allows to choose between `attachment` and `inline`

[downloadable] fix filename HTTP header for simple name with space (closes #2535715) Since d74addac92bb, we export simple ascii filename without any encoding in the `filename` parameter of the `Content-Disposition` header. If this name contains space this will fails, the parameter value will be truncated at the space position. (eg. `filename=jungle babar.txt` read as `jungle`) We need to quote the filename to prevent this (eg. `filename="jungle babar.txt"`). Then literal quote and backslash needs to be escaped too. The new escaping is correct according this extensive test case data base: http://greenbytes.de/tech/tc2231/

prepare 3.15.6

[web] add a digital signature to error form (closes #2522526) Simple (and quite weak) implementation of a digital signature of the content to be submited by email in the error report view generated by ErrorView. The signature is a simple hmac hash computed using a secret key (generated at repository startup) and the "secret" form content to be included in the notification email. The controller can then check this content has not been modified or forged by a malicious user.

[web/views] bugfix: the mime type is text/plain, not text/txt (closes #2526345)

[doc] fix of personnal etc directory in book

[web] add a Forbidden exception This is similar to the Unauthorized exception, but generates a 403 error instead of a 401 (Unauthorized)

[web] add a ``anonymize-jsonp-queries`` option in file configuration (closes #2465388) This option controls connection anonymizing before executing any query for CSRF / safety reason.

[downloadable] fix filename in HTTP header (closes #2522325, #2522324) Before this changeset we use the `filename` header with utf8 encoded filename all the time. However RFC6266 says: The parameters "filename" and "filename*" differ only in that "filename*" uses the encoding defined in [RFC5987], allowing the use of characters not present in the ISO-8859-1 character set ([ISO-8859-1]). Therefore, we alter the code to: 1. Use `filename` and `ascii` encoding whenever possible, 2. use `filename*` with `utf8` encoding otherwise (with a filename fallback for old browser) We also switch the `content-disposition` value to attachement if filename is specified, this will result as a mandatory download according to RFC6266. This mandatory download is the expected behavior. We changes the filename encoding to RFC5987 which is simpler, supported by all and modern browser (including IE from version 6) and does not suffer from the continuation issue. (see ticket #2522324 for details)

docstring typo

[facet] make BitFieldFacet allow special 0 value. Closes #2522697

[doc] ubuntu LTS is now Precise Pangolin

backport stable

[server] implement base_url with secure=True (closes #2508638)

[validation api] properly use yams 0.36 validation error api and update message catalog. Follows bbe0d6985e59 the creation of the `translate` method in the 23a10f049447 yams commit.

[wsgi] saner use of `self.config` instead of `config`

[server] fix repository initialisation Changeset d753d6a6798f was breaking database creation. Dropping the `config.creating` clause lead to trying to load the schema from database even in creation mode. Conditional are a bit altered and reordered to prevent this to happen.

[web test] make unittest_viewselectors work if rdflib isn't available

[js/ajax] documentation of 'reload' is missing an argument

[ldapfeed] move docstring to the class instead of the module

[hook] fix hook base class so access to __registries__ doesn't call check_event, only call it in registered callback. Closes #2517748
