Fix example in cw_set method

[merge] incorporate cw 3.17.10 fixes

Added tag cubicweb-centos-version-3.17.10-1, cubicweb-version-3.17.10, cubicweb-debian-version-3.17.10-1 for changeset fe0e1863a137

[pkg] prepare 3.17.10

[web] don't rename resources in gen-static-datadir We should use the result from WebConfiguration.locate_resource to know which file to copy, not what name to copy it to. The destination file should be the name of the resource, as the client will request it. This matters in the case of cubicweb.css which locate_resource might rewrite to cubicweb.old.css. Closes #3206129

[notification] avoid leaking cnxsets (closes #3243810) When sending notifications, we get each recipient as either an email address or a CWUser. In the latter case, we create a temporary session for that user and use it to send the mail. However, if we later decided to not send the mail after all, we'd leak the session and its cnxset. Add a try block inside the loop to make sure the temporary sessions are closed properly.

[book] English fix

[serverctl] complete the schema-diff command with options that will fix & enhance it. Notably: - filter out eids (doesn't make sense for the filesystem schema) - handle permissions, trying to detect the default ones Needs yams #174042. Closes #2996547.

[server] deprecate the old multi-source system It is removed in 3.19. Closes #2919299

[doc] document changed attribute default value storage

defaultval migration for sqlite

[schema] store default attribute values in a Bytes field, allowing python objects as default values Notes: * Binary objects grow two methods * we depend on a newer yams version * the code is quite simplified as a result of the whole change * a very old and nasty bug where bool(default values) evaluating to False not being properly migrated is killed Closes #2414591.

[source/native] fix sqlserver pattern matcher for unique constraints (closes #3227593) The matcher is used to parse the low-level error message and extract meaningful information for the end users. If broken, the users see an alarming and bewildering message. A full & definitive fix is scheduled for CubicWeb 3.18.

[dbapi] Fix broken inmemory:// URLs parsing (closes #3225832) ParseResult.path is what comes after the "domain name" in standard URLs. So in the case of 'inmemory://<instance' URLs, it is always empty. ParseResult.netloc contains the "domain name" part that we really want.

[metadata hook] rename an operation for the sake of readability

[book] Typo fix and rephrasing in devrepo/migration

[cwshell] rename history file to .cwshell_history (erudi is dead, long live cw)

[entity] Entity.related(): add a targettypes argument (closes #2957313) This allows to restrict the entity types returned by the method (passed to cw_related_rql). When such an argument is given, no caching happens.

[source configuration] silent lgc 0.60 deprecation warning

[web] remove action "Got Rhythm" (closes #3093362)

[debian] Break old geocoding It wants cubicweb.interfaces.

[wsgi] remove ages old hack to set base_url Its meaning has been lost in the mist of time.

[wsgi] also provide an example using werkzeug (if available) Related to #3005509.

[wsgi] add the simplest possible wsgi (debug) server This server is able to: * serve on a given port using the stdlib SimpleHTTPServer * run looping tasks Closes #3005509.

[querier/security] instrument a bit the querier read security checks Related to #2920304

[book] Improve PostgreSQL configuration section * Do not advice for specific PostgreSQL version (point to meta-packages if available in Linux distros); * First mention packages from Linux distros, put the link to official postgres documentation at the end; Closes #2725302.

[js] add a selector string escaping function will help use id strings in jquery selector expressions, e.g: "foo.[subject]:42" -> "foo\.\[subject\]\:42" Related to #3154531.

[merge] backport stable fixes

[test/ldapsource] backout 192a748550c7 which broke RQL2LDAPFilterTC

[rset] make sure rset.description is always a list It's more consistent, and avoids pylint warning "Instance of 'tuple' has no 'append' member"

[schema] edit syntax tree instead of playing with strings for RQLExpressions Lets us support more complex expressions involving e.g. "HAVING" clauses. Closes #3202855

[py3k] note about future warning on __eq__ vs __hash__ Closes #3179561.

[formfields] py3k kill future compat warning Related to #3179561.

[entity] do not raise an AssertionError if the kwargs given to set_relations/attributes is empty Regression was introduced in 3.16 with the new cw_set API. Old set_relations and set_attributes methods did not crash on empty kwargs. Closes #3104019.

[packaging] setup.py: don't exclude skeleton/debian/* from being installed Closes #3192725.

[tests/hooks/integrity] kill old and empty skipped test

[server/session] demote log to debug It can pollute the log very fast. Closes #3203391.

[server] fix a number of typos, mostly in docstrings

[skeleton] Install cubes README in Debian packages (Closes #3171971)

[debian] Build-Depends on python-unittest2 | python (>= 2.7) Closes #3175895.

[doc] typos and reformulation

[doc] additional documentation about pip install under both Windows and Debian

spelling: rollbacked -> rolled back

merge two default heads

[pkg] prepare 3.17.9

Use the list of sources instead of an iterator in update-feeds looping task This prevents RuntimeError due to dictionary size change that may occur (as a result of a new source being added) during iteration. Closes #3155843.

[security] fix dumb attribute error when inserting read security. Closes #3196891 This has gone undetected because of erroneous tests...

[entity] give a default reasonnable __eq__ and __hash__ to Entity Using the eid. Closes #3179560.

[debian] add some Breaks for backwards compatibility removal The person and comment cubes used to import the cubicweb.mixins module. The inlinedit cube relied on String.startsWith in javascript.

[js] remove 3.9 bw compat (where apparently unused) - cubicweb.ajax.js - loadxhtml: form.callback support removal - removal of top-level functions: preprocessAjaxLoad, reloadBox, replacePageChunk, loadxhtml - cubicweb.compat.js: - map is undeprecated (jquery.map being not an acceptable replacement) - removal of noop, contains, findValue, filter, addElementClass, removeElementClass, hasElementClass, KEYS mapping - htmlhelpers.js: use non-deprecated functions cw.urlEncode - cubicweb.js: - removal of startsWith and endsWith monkeypatches - note deprecated but still used stuff (for action) - test_utils.js: use cw.utils.sliceList instead of global function Closes #2782004.

Rename cleanup_interface_sobjects into cleanup_unused_appobjects Interfaces are gone in 3.18 Related to #2782004.

remove cw 3.9 bw compat (bw compat other than the interface -> adapter changes) - cwconfig, doc/admin/setup: docstring adjustment wrt 3.9 & virtualenv - testing/rst: windmill (which is gone from the testing infrastructure) - other docs: "stuff introduced in 3.9" cleanup, as we don't care about the version old features were introduced - server/hooky.py: bw compat for propagation hooks - server/schemaserial.py: pre CWUniqueTogetherConstraint migration support - web.__init__.py: dumps bw import - autoform.py: .action ppty is gone, also deprecate set_action and get_action - baseviews: CSVView.subvid gone long ago, secondary view removal - primary.py: _render_attribute & _render_relation signature change - reledit.py: rvid/default_value bw compat, should_edit_* dropped - webconfig.py: resourcefile is gone - formfields.py: old vocabulary handling - request.py: build_ajax_replace_url, external_resource Related to #2782004.

remove 3.9 bw compat In cw 3.9, interfaces are deprecated and replaced with adapters, yielding a lot of bw compat in many places -- most if this patch is concerned with the interface bw compat - cwvreg: interface cleanup - doc/adapters.rst: interface cleanup - entities/adapters.py, wfobjs.py: interfaces bw compat - entity.py: interfaces bw compat, also get_value, delete, attr_metadata, has_perm, set_related_cache, clear_related_cache, clear_related_cache, related_rql - predicates.py: score_interfaces & implements - interfaces.py & mixins.py: 100% gone - view.py: implement_adapter_compat, unwrap_adapter_compat - calendar.py, editcontroller.py, ibreadcrumbs.py, navigation.py, xmlrss.py: interface bw compat - treeview.py: salvage one function from mixins.py Related to #2782004.

remove 3.8 bw compat - cwconfig: old keys such as depends_cubes and non-dict dependencies - cwctl: fall back to docstring if no short descr, forget 'short_descr' - dbapi: session_data, get_session_data, set_session_data, del_session_data - dbapi & testlib, session: eid_key is gone - migractions: cachekey is gone - doc/datamodel/definition, schemaserial: BoundConstraint -> BoundaryConstraint - formwidgets: separator - primary view: render_entity_metadata Related to #2782004.

[hooks/security] Defer entity permission checks to an Operation. Some of these checks may currently happen twice within the same transaction and be costly. This should be semantically safe. If people rely on some internal transaction ordering to be allowed early (thus pass) while the condition wouldn't be met at precommit time, their application is broken. It however seems unlikely to happen in the real life (tm). Closes #2932033

[schema] drop very old bw compat (pre 3.5.10) Closes #2925085.

[devtools,etwist] rename TwistedConfiguration to WebConfigurationBase (follows #2919310)

remove "twisted" configuration (closes #2919310) This was also known as "web only" instances. Not used in production anywhere today.

i18n update

fix typos in workflow constraint error messages

[migractions] rschema.final.inlined -> rschema.inlined Closes #3153086.

[server] Make internal sessions not reset 'safe'-ness on first commit Increment the ctx_count when disabling integrity hooks so the next commit/rollback doesn't reset our transaction and magically turn us into a safe session. Closes #3168027

[facets] Correctly replace old 'edit box' HTML on facet-induced page refresh (closes #3161100)

[debian] replace find | xargs rm with find -delete in cube skeleton. Closes #3161797

[debian] don't require (fake)root to run the clean target. Closes #3161797 It works just fine as a normal user.

[debian] Add ${misc:Depends} to cube packaging skeleton. Closes #3161797 Best current practice is to have that in Depends in all packages using debhelper.

[devtools] fix race when creating backupdir If somebody else creates backupdir between our stat() and mkdir() (like, say, another test running in parallel), we shouldn't crash.

[staticcontrollers] Raise Forbidden, not Unauthorized Unauthorized means "log in to get access", as it results in a HTTP 401. Here, the error is pretty much permanent, and returning 401 instead of 403 confuses things terribly. (This seems to be a pretty widespread confusion :/)

[web] allow /data/ url again (closes #2464798) This feature was broken by 65fecbeb9c3a (which fixed another one itself).

[utils] fix typos in make_uid docstring

[c-c i18ncubicweb] fix crash, closes #3096647

[rql2sql] fix bad sql generated when outer joining 'identity' relation and lhs var comes from a subquery. Closes #3099418 The generated SQL was attempting to access table.cw_eid which doesn't exist.

[web] stop using deprecated StatusResponse. Closes #3098215

[deprecation] add (approximate) version number to deprecation message and set proper stacklevel

[repository] properly use IUserFriendlyError when UniqueTogetherError is raised during entity update. Closes #3096638

[deprecation] add cw version number to the deprecation message and help user to understand the change

[datafeed] fix crash due to bad http_timeout handling. Closes #3096585

[date picker widgets] properly distinguish DOM id and input name. Closes #3096575

[date picker widgets] use bare jquery expression rather than jqNode

Use return in CnxSetTracker context manager methods Just in case.

[web/views] make PrimaryView.entity_call accept kwargs It's useful when using this view in a different context to have it not crash on random arguments.

[ldapparser] demote some logs from warning to debug (closes #2713671)

[doc] add a what's new file for 3.18

merge stable in default (3.18) branch

Added tag cubicweb-centos-version-3.17.6-1, cubicweb-version-3.17.6, cubicweb-debian-version-3.17.6-1 for changeset 5b9fedf67a29

[pkg] prepare 3.17.6

Do not use cubicweb-card in rest_path tests Card overrides the rest_path method, so it does not make sense to use it in cw tests.

[inlined form field] fix regression introduced in 3.16.4/570208f74a84. Closes #3064653 In the above changeset, we changed ordered entities to be edited according to mandatory inlined constraints, though this leads to unpredictable order in cases where there are no constraint. This leads to case where inlined relation field may think there is no value related to a mandatory relation, while this is simply because there is a value specified but to an entity that will be created later (together with the relation). To fix this, we've to use the fact that the RelationField.process_form_value return None in cases where there is some entity to be created, while an empty set when there are no linked entity. The new no_value() method allows to differentiate between those different notion of 'no-value'.

[testlib] temporary_appobjects should call __registered__ if it exists. Closes #3064075

[entities] properly escape in EmailAddress.printable_value when format is html. Closes #3064025

Added tag cubicweb-version-3.17.5, cubicweb-debian-version-3.17.5-1, cubicweb-centos-version-3.17.5-1 for changeset 15dd5b37998b

[pkg] prepare 3.17.5

[pkg] fix debian packaging (closes #3058542) - remove useless Python 2.4 reference, - simplify dh_install configuration to install files consistently instead of having half in /usr/lib/pythonXX and half in /usr/share/pyshared, - incidentally, this makes the package work on squeeze. Regression from eaa58d1c7d5f

[testing] add missing generate_bigint method to ValueGenerator. Closes #3059327

[rql / querier] fix bad interpretation of some RQL SET query when some neged relation is involved. Closes #3058527.

merge stable in default (3.18) branch

Added tag cubicweb-version-3.17.4, cubicweb-debian-version-3.17.4-1, cubicweb-centos-version-3.17.4-1 for changeset c7ba8e5d2e45

[i18n] cleanup dead code also fix small bug introduced in b0f6e8c14e7f

[i18n test] hack to make i18n tests run using a Python interpreter they used to work fine when executed via pytest only. This should be removed as soon as logilab.common.registry is fixed.

[i18ncube] fix crash due to duplicated messages in generated schema.pot Add a test case and fix regression introduced in e713c47a993d. Relates to #2811282

[i18n test] load_po: fix bug in case of multi-lines msgid and ensure there are no duplicated messages

[i18n test] simplify test cube a bit by only providing a views module, no package

[web] consider inlined relations in has_editable_relation. Closes #3049970 In some cases where the user can only add/edit inlined relations (though actually edit perms of the inlined relation doesn't seem checked), the "modify" action doesn't appear while it should.

[web test] silent 3.13 warning

[editcontrollers] Account for role in the ordering of entities (Complements #3031719) Only role='object' was correctly accounted for by 570208f74a84

[session commit] save back exception context to avoid potentiel cluttering if some revert operation raise an exception

[pkg] python-central has been removed from Debian

[pkg] prepare 3.17.4

[pkg] merge centos 3.17.1-2 in stable (prepare 3.17.4)

Added tag cubicweb-centos-version-3.17.1-2 for changeset 965f894b63cb

[rqlrewrite] fix rqlrewrite unpredictability vs relation sharing. Closes #3036144 The relations index used to determine if relation may be shared only considered a single relation node per relation type. So when the same relation type occurs several time, dict order give unpredictable result. We shall properly consider all relations instead. Tentative test case included (but bug reproduction is by definition unpredictable...)

[rqlrewrite] rewrite doesn't need a solutions argument, always use the Select'ones Also, do a copy systematically else it may lead to empty solutions depending on the rewrite path. Test case tentative included in the following changeset.

[rql rewrite] equivalent but much simpler flow

[pkg] Prepare a new RPM release

[pkg] Add log directory to rpm

[repo] normalize ValidationError on edited entity (closes #2509729) In CubicWeb, ValidationError.entity MUST be the eid of the involved entity, not the entity iteself (as done by yams).

[doc] one must now manipulate the req.session.data dict (closes #2842345) instead of deprecated get/set/del_session_data methods.

[datafeed] add a timeout config option (closes #2745677) So a HTTP GET do not hang forever in the datafeed looping task.

[dataimport] ucsvreader should skip empty lines unless specified otherwise. Closes #3035944

[querier] Add timings to debug prints (DBG_RQL) this may ease to spot some problematic queries

[editcontrollers] Ensure entities are created in an order satisfying schema constraints. Closes #3031719 changes below are also necessary to make the whole thing works: * stop considering InlinedFormFile as eidparam field since they don't hold any value * rework 'pendingfields' handling to have separate processing of inlined fields whose subject entity is created during the edition

[editcontroller] extract RQLQuery.set_attribute/set_inlined methods from handle_field/handle_inlined_relation

[editcontroller] req=self._cw makes things easier to read

[facets,js] fix bogus checkbox icon appearing after the first interaction (closes #2790332) This is because of the hardcoding of the data/ url.

fix typos in docstring, doc and comments

[debian] remove workaround for broken sphinx/jquery combination sphinx in squeeze was updated: http://packages.qa.debian.org/s/sphinx/news/20130112T154737Z.html

[schema] mark CWDataImport as an internal type. Closes #3025536

[pkg] remove deprecated dependency on pysqlite2

Fix two crashes in db-check (closes #3024964) Also improves various debugging messages.

[rql rewrite] may_be_shared_with should consider relation's scope (closes #3024730) When a relation's scope is not the current statement, it must not be shared (instead of comparing the statement).

[rql rewrite] fix may_be_shared_with method so that it actually considers all variable infos and not only the first one

[schema/security] add __hash__ to rql expression. Closes #3013535 This is required so that when some rql expression participate to a dictionary key, only the expression is considered (consistent with comparison). This behaviour is expected in security at least, see the related bug for instance. This scramble msplanner unit tests a bit.

[rql rewrite] move some code from querier to rqlrewrite where it makes more sense. Also, make some minor cleanup/refactoring on the way and try to enhance docstrings. Relates to #3013535

Do not compute actions list in TableLayout view when display_actions attribute is unset Closes #3007281

Use the list of cubes from the filesystem when reading the schema from the filesystem Closes #3007259

[migration] when adding a cube, skip infered relations (closes #3005576) Skipped infered relations are recalculated later.

[3.17 migration] when some cube is missing, add_cube raise ConfigurationError, not ImportError. Closes #2981477

[migraction] rename_entity_type simply warn if old entity type isn't in the schema. Closes #3004069

[deprecation] fix uihelper deprecation warning, use the rtag name, not the class, so it may be copy/pasted

[test] makes fti test order-agnostic (closes #3005633)

[web/views/staticcontrollers] Make ConcatFilesHandler write to a tempfile In order to be more resistant to errors such as ENOSPC, and against different threads accessing the same static data, we: - concatenate data files to a temporary file, and rename it once we're done - delete the tempfile in case of errors - protect the creation of the cache_concat file with a lock Closes #3005547

[test] make unittest_schema.py compatible with cubicweb-file 0.14

merge 3.16.6 branch in 3.17

Added tag cubicweb-centos-version-3.16.6-1, cubicweb-debian-version-3.16.6-1, cubicweb-version-3.16.6 for changeset b4ccaf13081d

Prepare 3.16.6

[devctl] properly generate i18n messsages for cubes that uses uicfg instances (closes #2811282)

[test/devctl] add a test case for i18ncube command

Protect against crash in the `relation_possible` predicate with ambiguous relations. It was still possible to get a KeyError when using relations that are ambiguous at both ends, like (Executable, version_of, Program) & (Version, version_of, Project). Closes #3010148.

[test] give a non-ambiguous order to sync_schema assertion (closes #3001959) Sorting by ordernum alone is unstable since several values have the same ordernum. ordernum + name should be stable.

Added tag cubicweb-version-3.17.3, cubicweb-debian-version-3.17.3-1, cubicweb-centos-version-3.17.3-1 for changeset 32b4d5314fd9

[test] typo

[schema,server] add a security debugging aid (closes #2920304) - Add a DGB_SEC debugging flag (to be used with set_debug/debugged). - Add a context manager (tunesecurity) to filter security assertions. Note: this does not address all read-security mecanisms.

[etwist] fix handling of multiple files per field html5 permits multiple files uploads, which can be expressed as:: <input type='file' multiple='multiple' /> This changeset avoids previous crash. Nothing is changed when a single file is uploaded (backward compat is thus preserved). When multiple files are uploaded for a single html input tag, the corresponding web request form key receives a list of tuples like [('filename-1', IStream1), ('filename-2', IStream2), ...]. closes #2847207.

[merge] start 3.18 development

[pkg] prepare 3.17.3

[pkg] Remove obsolete ubuntu hardy packaging It's been EOL for a while.

[book] fix sphinx documentation generation (closes #2991997) changeset 17994bf95d6a ([doc] update Session documentation) added cubicweb.server.session.Session autodoc to the book. This caused errors from sphinx due to a section title not being allowed in the class's docstring.

[test/ldap] fix ldap tests - make sure the url is properly updated on database setup (when the test database already exists and the ldap URI has changed) - fix the ldapuser test setup process.

[test] fix unittest_schemaserial.py A spurious add permission has been added in expected result by d988eec2d5d3

[test] make unittest_schemaserial.py runnable with python used to run fine only when launched using pytest

[facet] use facet name as input name for text widget (eg has_text) we need to ba able to distinguish between text-inputs so we can write a widget for a single facet that uses more than one text input. This fix consists in the diff in cubicweb.facts.js; modifications in facet.py result from this former.

[web doctype] don't give through reset_xmldecl to avoid double deprecation warning

[web doctype test] don't give reset_xmldecl to avoid deprecation warning

[devtool] randomise available ports search in http test This lowers the chance of parallel tests to race for the same port.

[facet] don't crash if no title specified on a facet and filtered rset is empty. Closes #2587883

[css, html] add a css_class attribute on Button, allowing to change easily default CSS class for buttons (think orbui integration)

[view] add 2 missing spaces before the previous link

[server/repository] Go through the repo to close pyro sessions Turns out session.close() doesn't DTRT.

fix migration from pre-3.13.1 versions (closes #2846978) Need to check the existence of the asource column before the first call to eid_type_source.

[constraint] more robust unicity constraint failures reporting for end-users Postgres or Sqlserver have limits on the index names (around resp. 64 and 128 characters). Because `logilab.database` encodes the `unique together` constraint rtypes in the index names, we sometimes get truncated index names, from which it is impossible to retrieve all rtypes. In the long run, the way such index are named should be changed. In the short term, we try to reduce the end-user confusion resulting from this design flaw: * in source/native, the regex filtering ``IntegrityError`` message does not impose an `_idx` suffix, which indeed may be absent (the result being an UI message that resembles a catastrophic failure), * also we avoid including a trailing " (double quote) from the error message * in entities/adapters, the well-named ``IUserFriendly`` adapter is made a bit smarter about how to handle missing rtypes. * the adapter also always produces a global message explaining the issue (and the fact that sometimes, the user is not shown all the relevant info) * i18n is updated Closes #2793789

[hooks/security] Streamline attributes default permission check. The current default permission on attributes delegates the check to the entity permission update policy. Since this is already checked it can be skipped. The equality comparison will work, even with a deserialized schema, because the default update perm is:: ('managers', ERQLExpression(Any X WHERE U has_update_permission X, X eid %(x)s, U eid %(u)s)) which will always be deserialized in this order (groups first). However this is a slight semantic change: entity type level 'update' permissions can now be effectively used to encode update-time rules if the default attribute permissions are used (before this change, the 'update' rules at entity type level were fired at creation time). Closes #2930861.

[test/schemaserial] swap got/expected to get nicer unittest2 diagnostics Prepares #2965518.

[repository] drop safe attribute on ``internal_cnx`` People that need to disable hook can do it explicitly anyway.

[dbapi] deprecated the dbapi

[repoapi] deprecate dbapi compat method

[testlib] deprecated the older api to access the repo.

[connection] deprecated free_cnset and set_cnxset

[session] deprecate all Connection related method on session

[session] drop dead _current_cnx_id Not used anymore for a few commit.

[session] privatise get_cnx and close_cnx The only user, repoapi now use ``new_cnx``

[doc] add documentation for the new API in test

[testlib] add an default testcase.adminaccess (and use it for default session) This adminaccess is the new offical way to get connection, and request on a repo.

[testlib] introduce a RepoAccess class to easily create connection and request Each RepoAccess hold a session for a user and three helper function to help create Connection, ClientConnection of WebRequest related to this session. related to #2920299

[repoapi] make ClientConnection.__enter__ return self This allow the standard idiom:: with repoapi.connect(repo, login='babar', passwork='elephant') as cnx: cnx.execute(…)

[documentation] describe repoapi and web side change. Short version explaining what object replace what and that BC existes for a few version.

[testlib] use internal_cnx instead of internal_session internal_session is deprecated.

[repository] add an ``internal_cnx`` method to replace ``internal_session`` Accessing the repo through a Session is deprecated. We need an easy replacement for ``internal_session``. This API change was a good occasion to stop disabling integrity hook by default. This is huge source of bug in user-code. related to #2503918

[connection] enforce that a connection must be open to be used The same than for ClientConnection, we ensure the connection is used inside a its context. .. note:: We may rely on that for ClientConnection and remove de dedicated code in Client Connection but I prefer the current explicite and duplicated version for now.

use standalone Connection to Client Connection

[session] add a new_cnx factory Having user-code importing cubicweb.server.session.Connection is inconvenient. We add a simple factory fonction on the session.

[connection] allow simple instantiation of standalone Connection Such connection will automatically pick a connection id. Note, They are not automatically closed on session close. But they will fails to grab new cnxset once the session is closed.

[connection] handle and explicitly life cycle on Connection Like ClientConnection, Connection object need to be explicitly started and stop. They aims to be used as context manager.

[sesion] distinction between Connection handled by the session and other. Not mixing the new and backward compat approach seems a good idea. Let's enforce it.

[session] replace _clear_thread_storage with close_cnx There is not good reason to keep two distinct method.

[session] explicitly take Connection object in close_cnx Now that ClientConnection explicitly reference and use the Connection object we do not need to use connectionid here. We can safely change this signature, ClientConnection is the only use of close_cnx for now.

[session] drop the Session._clear_cnx_storage method It is just cnx.clear() now.

[session] wrap too long line Too long line is too long. (Confucius 503 BC)

[session] gather close_cnx with get_cnx and set_cnx They do the same kind of operation and deserve to be grouped together.

[client-connection] remove the _srv_cnx usage It does not do anything special now that we use explicite Connection object with automatic cnx_set handling.

[client-connection] explicitly check that the client-connection is open The check is also perform by the _srv_cnx property. But we do not need those property anymore.

[client-connection] handle the lack of connection id while not open the connection id is computed at opening and forgotten when closing. We can't rely on it in various messages … like the "connection closed" exception.

[connection] transparent cnx_set handling Connection object while take cares of there cnxset themself (as dbapi connection does). The ``set_cnxset`` and ``free_cnxset`` operation are still available for backward compatibility purpose. The ``_auto_free_cnx_set`` is introduced to handle mixed usage. A new context manager ``connection.ensure_cnx_set`` is added for code that access ``cnx.cnxset`` directly and are not wrapped in any specific ``Connection`` method. A ``_with_cnx_set`` decorator is used on all Connection method that need a cnxset.

[client-connection] explicit the client part in __repr__ Now that we have real server side connection we need to remove ambiguity.

[ClientConnection] directly use the Connection object to access the database Now that Connection are a full featured standalone object we can directly reference and use it in the ClientConnection instead of using the session. The session object is kept around for a while to perform various utility role.

[connection] invert __init__ parameter Takes session first. At some point, the connection_id will become optional for Connection created explicitly.

[service] enforce that Service argument and return are json-serialisable The call_service API need to be able to run through RPC. So we ensure front start that it is possible serialise both input and output.

[connection] move call_service on Connection This is the last step toward standalone transaction.

[connection] move the commit method on Connection object One step closer of standalone Connection!

[connection] move the rollback method on Connection object One step closer of standalon Connection.

[connection] pass a Connection object to RQLRewriter RQLRewriter can now directly use a Connection object. No need for specific handling session side.

[connection] Connection.execute touch Session timestamp This allow to keep Session alive while using Connection object only for database access.

[connection] Connection now call _set_user to CWUser object linked to itseld Session.user is linked to the session.

[server/session] better faking of user for InternalManager

[connection] move execute All necessary method are now available on the Connection object. So the Connection can handle RQL execution itself.

[connection] mark Connection as "not a request" The ORM use this information. Having a wrong value will lead to crash.

[server/session] ensure appobject obtained from the session are linked to the session

[connection] have rql_rewriter accession on Connection Code expecting a session search the RQLRewriter on this attribute.

[connection] move local_perm_cache management on Connection It belongs here anyway.

[session] use a rich object for timestamp This allows the Transaction to keep a reference to it

[migraction] do not access session.data directly use set_shared_data and get_shared_data instead

[connection] move relation management method

[connection] give access to shared data method A reference to session data are kept

[connection] move relation cache method to Connection needed for execute (and need execute themself...)

[connection] give access to session execute from connection This allows multiple function that both requires an execute method and are required by the execute method.

[connection] move last part of undo logic in connection Now that Connection have a reference to the repo it can handle all of it itself

[connection] initialize connection.user and connection.lang A RequestSessionBase need a user and lang. For now we use the session ones. Later the Connection will have it's own.

[Connection] inherit from RequestSessionBase This contains a lot method. We need them to move more code from Session to connection.

[multi-sources] drop multi-sources related test. another branch is removing the multi-source itself. We do not want to bother fixing those test.

Use new repoapi for the web stack The publisher now link repoapi.ClientConnection to request. and explicitly control there scope. Web side, appobject._cw.cnx is now a repoapi.ClientConnection. This actually kill webonly possibility until the repoapi is able to use some RPC. The change in the authentication stack is very hasty and need cleanup
