[entity] improve deprecation messages

[devtools] use self._parse so AssertionError is properly raised instead of lxml error (test failure introduced in 6711f78c18be)

[testlib] fix page validator selection. Closes #2869456 * use a validator that checks XML well-formness for the html5 doctype (as a convenient side-effect, it does not choke on e.g. a canvas tag like the HTMLParser does) * use a DTD validator if there is an xml declaration * else use the HTMLValidator

[testlib] introduce a validator that check xml-well formness This validator simply check XML is well formed and accept any entities (think HTML defines much more entities than bare XML)

[view] return HTML5 doctype. Closes #2869426 We dropped xhtml support in 3.17 but we kept providing documents using the XHTML strict doctype, while our content wasn't conform to the DTD since we dropped proper namespaces definition as well as declaration of cubicweb DTD extensions.

[testlib] repreprocess content so contextual display has a chance to show the proper line. Closes #2869481 the context is calculated using position information relative to a preprocessed content, not the original source

[web request] drop no more necessary request.document_surrounding_div method This is awful and no more necessary since we dropped xhtml support

[testlib] unspaghettify Validator / PageInfo api

[testlib] update htmlparsers.VALMAP: stop using SaxOnlyValidator and add an entry for html

[testlib] SaxOnlyValidator is deprecated, use XMLValidator instead

[dataimport] minor typo in error handling

[views] attempt to clarify the inline help system documentation

[sobject] fix notification operation regression introduced in bf4003760e02 Operation use self. session. not self._cw. I'm a bit surprised that its not tested. closes ##2870077

Added tag cubicweb-debian-version-3.17.0-2 for changeset 09a0c7ea6c3c

[pkg/debian] prepare release 3.17.0-2

[pkg/debian] update yams runtime depends Only the built depends were updated to 0.37.0.

[pkg/debian] expand all depends and co on multiple line This is more readable and simplifies patching.

Added tag cubicweb-debian-version-3.17.0-1 for changeset 22be40c492e9

Added tag cubicweb-version-3.17.0 for changeset cc1a0aad580c

[test/view] exclude some Blog entity from automatic view testing Some Blog view requires the sioc cubes that we extracted in 3.17 we do not really want to test cubes view here. So we exclude CWEtype that really requires the sioc cubes.

[doc] fix: cubicweb.gmap.js has moved to the geocoding cube

[test/ldap] do not assume order Do no assume a specific order is stable when testing group members

Added tags for version 3.16.4 on changeset 041804bc48e9

[notification] ensure official API is test By using the official API in the hook we ensure it is tested.

fix typo in notification causing NameError introduced by: f5b40b66d36e

[test/notification] merge related test classe They have no reason to be distinct.

merge with stable

[server] add a looping task to free unused cnxsets capture by dead pyro When a pyro client disconnects, we're not necessarily notified so they can hang on to their session/cnxset forever. Don't let them do that. The hacky looping task is only installed when pyro is enabled. This optional activation save this very hacky patch from being rejected. closes #2825380

[pkg/debian] update changelog to 3.17.0

[devtools] Use XMLValidator instead deprecated SaxOnlyValidator The renaming was introduced in 198fdadafed6.o This prevent a meta class conflict introduced by logilab-common 0fcd2e050621.

[pkg] update changelog

[pkg] prepare 3.17.0

[pkg] prepare 3.16.4

[repo] straightforward bootstrap sequence. Closes #2841188 * kill fill_schema method which was doing to much different things, in favor of a deserialize_method which is simply reading schema from the db and returning it * set_schema doesn't bother with cubes This allows to easilly follow what's going on and so to cleanup init_cnxset_pool to get the following boostrap order: 1. load cubes (implies loading site_cubicweb) 2. load schema 3. init data sources 4. init cnx sets

[repo] minor cleanups to bootstrap sequence * fix some docstring/comments * move initialization of HooksManager to the __init__.py, this has nothing to do with pool initialization / boostraping

[schemaserial] serialize additional yams parameter for customs type Yams have a new custom type feature. We add support for extra parameter on CWAttribute in schema serialization handling. Closes #2847151

[sql] preprocess_entity uses lgdb helper's SQL converters. The preprocess_entity does not yield anymore the conversion logic for different base types, but relies on a new SQL_CONVERTERS dictionary of the db helper. This will allow later inclusion of new base types.

[repo] kill rebuildinfered feature from Repository.set_schema This clutters thing and is useless in most cases: when schema just have been readen from the database or from the file-system, infered relations have just be calculated. The only use-case where it should be rebuilt is on migration (ie schema modification by editing the meta-model using rql), so move this feature there.

[test] stop deepcopying for nothing

drop xhtml content-type support (closes #2065651) * HTMLStream does not care about xml any more * reqquest.demote_to_html and .xhtml_browser are deprecated * web config: drop force-html-content-type option * adjust tests

[htmlparser] exclude <script> tag from html source lxml are confused by them :-(

[htmlparser] store unaltered source in pageinfo.source Do not store the parser to preserve the source aspect. Store the initial input in the source argument instead. This is very useful when parsing html. In such case we need to drop ``<script>`` tag.

[htmlparser] rename SaxOnlyValidator to XMLValidator

[htmlparser] add missing deprecation message

[form] remove hard coded id html id should be unique. It is clearly not achieved here.

[server/test] use server config in migration This allows a lighter initialisation (no rtag needed). Execution of those test move from 300 secondes to 220 seconds here. A 25% speedup

[session] deprecate `hijack_user` method The semantic of this method is wicked and lead to very hard violation of sanity. (multiple transaction using the very same cursors). We deprecated the API to be able to drop it as soon as possible. The method was added long ago for some notification trick. It is not needed since we sent notification on ``postcommit_event``. (closes #2781782)

[mail] drop hijack_user usage The transaction is now commited before notification. We can create a new session directly and drop `hijack_user` usage. This prepare #2781782

[notification] merge BaseNotificationView and NotificationView They are in the same module now.

[notification] move notification view in ``sobject.notification`` It has no user outside this module. This enforce serversideness of notification and allow future cleanup. No backward compat is set up to prevent circular import. The class has no other user anyway. (closes 2845144)

remove unused import pyflakes say they are unused. Tests suite confirms.

one more merge

[notification] introduce an official `notify_on_commit` function It provides a proper notification api instead of replacing it by yet another clumsy one. Closes #2837251

[cubicweb/doc] Replace dc_type() by cw_etype dc_type() is may be translated. Leading to terrible terrible damage.

[dataimport] backout 6947201033be (related to #2788402) (and add a try: except to cache the intended error) The problem actually comes from the ``MassiveObjectStore`` in the ``dataio`` cube, so it should be corrected there. Here, we only protect it with a ``RuntimeWarning`` so that the user can see the problem. ``value`` is set to ``None`` (whence to ``NULL`` from a database standpoint), so that the data can be nevertheless inserted in the database. However, only the keys present in ``row`` are actually non-'``NULL``'. The real solution is to work out the issue in ``MassiveObjectStore`` directly. The current try/except should only be a temporary hack.

merge default heads

[c-c serverctl] import locally to speed up c-c

[facet js] minor refactoring and cleanups * extract facetCheckBoxSelect and facetCheckBoxUnselect * use $ as prefix for jQuery variable (facet -> $facet) * other minor rephrasing

[ldapfeed] Add support for LDAP groups (closes #2528116) Groups from the LDAP server are imported as CWGourp entities, and in_group relationships are created between existing CWUsers and CWGroups Unit tests have been refactored a bit, especially ti add helper methods to manage LDAP database.

[test/ldap] small improvement to ldapfeed unit tests better group testing and further testing of imported user life cycle.

[ldap] prepare import of CWGroup All CWUser specific code is put in dedicated sections.

[ldap] handle modification date We are now able to import modification date from ldap.

[ldap] refactor attributes mapping handling * use explicit attributes lists when calling ldap search * direct and reverse attributes maps contains now the same elements.

[ldapfeed] add support for multiple email addresses from ldap Multiple emails case was ignored before this change. email test

merge 3.16.x fix in 3.17.x branch

[session] fix hooks_control backward compat Session object have no ``hooks_control`` control method. it has ``allow_all_hooks_but`` and ``deny_all_hooks_but`` ones. Regression introduced in bd5b5759c9b3.

[facet js] fix reordering of facet check boxes. Closes #2732947 Before this patch, when one select an element, it's moved to the top of the select content. Fine. But when it's later deselected, it stays there instead of moving back to its original location. This patch fixes that by introducing a facetCheckBoxReorder function which properly reorder the whole facet, instead of buggy attempt to locally reorder.

[vreg] (re)build entity classes cache after registry initialization. This fix potential memory fragmentation issue. Closes #2719113

[task] allow negative intervals for add_looping_task (closes #2818280) Instead of rejecting values < 0 with a ValueError, we ignore tasks with a negative interval. This introduce a simple way to disable task from configuration.

[task] allow interval=0 for looping tasks There is valid usecase for perpetual running task.

[portable dump] skip virtual relations, they have no table associated. Closes #2841199

[test] fix skipIf import, currently failing if unittest2 is not there

[test] fix bad merge

merge with other default head

[ldap] an empty 'user-base-dn' disable the user importation process, The same semantic will be used for group. We start by using it for user for the sake of consistency.

drop commented print

[ldap] Major test refactoring Mostly fix tests (previous refactoring), but also refactor a bit the base class to have better/simpler interaction with the slapd server.

[test/ldap] have RQL2LDAPFilterTC use its own database I do not know what RQL2LDAPFilterTC is about and why it does this strange reuse of LDAPUserSourceTC pre_setup_database but it is certainly a good idea to have it use a dedicated database-cache.

[ldap] quieter tests Capture slapadd and slapd output if everything goes well.

[test/ldap source] better source naming, some cleanups (prepares #2528116) ldap uri becomes "ldap" in all cases prepare separation of CONFIGs by source type

use cw_etype instead of __regid__ We have a clean public API now.

[entity] add an official ``cw_etype`` property for entity This property holds the CWEtype id of the entity. This information was previously available through __regid__ but this is an ugly public API. So we have a new clean public API. The ``dc_type()`` method could not be used as it is translated. (closes #2793792)

[notification] use new style operation for notification This results in far less operations created. Operation creation is expensive. We keep some compatibility with the previous API because some cubes have been reported to use it.

[cleanup] drop code deprecated since 3.6 The 3.6 API have been dropped some time ago. Those three lines survived the purge. One of them is even deprecated since 3.5.

[notification] fix documentation The doc say precommit, the code says postcommit. The code is right. We also clarify the documentation of another related operation looking suspiciously wrong but actually correct.

[ldapuser] Deprecated the source We have ldapfeed for some time. maintaining both is cumbersome. This old style source will be dropped in 3.18. closes #2567712

[rql2sql] Remove an XXX by explaining why Int non-substitution is desired (in the current state of the API)

[rql2sql] Boolean values should be substitued like others. Closes #2829481 Furthermore lgdb 1.10 deprecate boolean_value method and this simplify testing.

[toward-py3k] rewrite __cmp__ (closes #2715115) In Python 3k `__cmp__` special method is no longer supported. So we split it in `__lt__` and `__eq__`. details on Python3k behavior here: http://docs.python.org/3.0/whatsnew/3.0.html#ordering-comparisons

skeleton: add RPM spec template (closes #2800884)

[clean_session] revert itervalues usage from 0bb18407c053 self.close(session) changes the self._sessions content. We need to create a full list of value before starting closing them.

merge 3.16.x fix

[ldap] Use correct API for logging message The good practice cat prefer logging to do the substitution himself.

Fix obsolete docstring for add_looping_task The docstring was telling lies since changeset cae198371548 "add_looping_task can be used any time"

[devtools] prevent Xvfb resets Seems like firefox opens more than one connection to the X server in some cases, and things get utterly confused.

[LDAP] rename unittest ldapuser to ldapsource (prepares #2528116) the tests involved are not only for ldapuser module but also for the more general ldapfeed Necessary to prepare LDAP patch for CWgroup

[devtools] protect xvfb-run.sh against clean_up being called twice

[service] make sure synchronous call_service has a cnxset Fixes regression in 3.16.2 (closes #2807720)

Merge testfunc testfunc resurrection Closes #2535377

[web] move qunit test back into web and fix the hanging qunit test can not work outside web. a lot of try/finally clause have been added to prevent qunit to hang on error. A not a test a indeed broken. But we at least put in them a running state again..

[test] drop forsaken windmill test (Closes 2535376) * not run since multiple years * windmill itself is in poor shape not even packaged in Debian. The peace which other seek they find; The heaviest storms not longet last; Heaven grants even to the guiltiest mind An amnesty for what is past; When will my sentence be reversed? I only pray to know the worst; And wish as if my heart would burst.

[server/test] remove dependency on a pyro name server (closes #2801737) Use a direct pyroloc:// url instead of going through a NS.

[packaging] add spec file to build RPMs (closes #2800850)

[predicates] keep making `yes` predicate importable from cubicweb (closes #2790319) The `yes` predicate was moved out in CubicWeb 3.15 but it should have remained importable from the cubicweb.predicates module, for bw compat reasons and also because logilab.common.registry is an implementation detail.

[views/tables|css] backout rev 895e34d9ae0d This changeset introduced a GUI behaviour change that has usability side-effects (eg. shows a non-undoable massive action as a first-class action). The idea is good, but it requires a better implementation; tabs are not the proper GUI solution to the original usability issue.

[webconfig] cleanly handles ``fckeditor_installed`` when no uiprops The previous version of the code relied on a default value with a dummy ``FCKEDITOR_PATH`` entry. The new code check if uiprops is initialized or not.

[webconfig] fallback to default configs if https ones are not defined When cubicweb serves a request with an https scheme, it tries to access ``https_uiprops`` and ``https_datadir_urls``. However if those are not defined we should fallback to unsecure url instead of crashing with a traceback. There are very valid usecases for undefined https url. For example if your ``base_url``, ``datadir_url`` and uiprops content are already https urls. Closes #2786643

[webconfig] explicit some webconfig attribute Explicit declaration of attribute are much clearer. Just do it.

[querier] fix eid relations handling in SET queries (closes #2797052) _extract_eid_consts() implementation must consider arithmetic operators when trying to associate rql variables to specific eids.

[ext/rest] add directive bookmark to rest (closes #2545595)

[c-c create] make post-create step optional (closes #2712041) In this context the "post-create" step refers to the database's creation and initialization. We want to be able to create a new instance but skip the database creation (`db-create` and `db-init` commands) in automatic setup.

[cwconfig] Add optional configuration param to load a UI cube before other cubes Needed later on to load UI cubes such as legacyui, and one day squareui.

[web/views] Move massmailing to its own cube (closes #2788086)

merge with stable fix

[req] explicit `user` attribute The `RequestSessionBase` object needs a `user` attribute. It is initialized by sub class, but having it explicitly declared is much cleaner.

[test] use the right order in some assertEqual The unittest2 function use ``(expected, got)`` order.

[session/transaction] move resource accessors on Transaction

[session/transaction] move multiple utility on Transaction

[session/transaction] handle cnxset repository logic in transaction Interacting with the repo is now handled by the Transaction code directly.

[transaction] keep a reference to the repo object

[session] make security_enabled API private The doc already says "internal API". The old entry point is now officially deprecated and the context manager have been made private.

[session] make hook_control API private The doc already says "internal API". The old entry point is now officially deprecated and the context manager have been made private.

[service] split session retrieval and service execution Internal session are not tracker by the repository and can not be retrieved using _getsession. Moreover their session id is not unique… Closes #2735700

[service] handle cnxset in the async case only The service may be called by a session, we really do not want the call to service to mess with the transaction state. This does not apply to async were thread magic ensure a dedicated transaction.

[service] extract session retrieval from "task" closure The session was retrieved there because `set_cnxset` must be called in the same thread as the code using it. We now retrieve the session beforehand and explicitly call `set_cnxset`.

[cubicweb/doc] Add tutorial on data import in CubicWeb. This involves creating the "tutorials/dataimport" directory structure under "cubicweb/doc" and, inside the "dataimport" directory, putting several files: - a ResT file containing the tutorial *per se*; this tutorial addresses the following issues: * creating a CubicWeb schema for representing a given data set (here, the Diseasome RDF data, for illustration purposes); * parsing the data; * importing the data, by using several stores: + the ``RQLObjectStore``, ``NoHookRQLObjectStore`` and ``SQLGenObjectStore`` from the ``dataimport`` module in CubicWeb; + the ``MassiveObjectStore`` from the ``dataimport`` module in the ``dataio`` cube. The tutorial also provides timing benchmarks of the various stores. - a set of Python files illustrating the data import, in the context of Diseasome RDF data parsing: * a Diseasome RDF data parse module, * a Diseasome data import module, * a CubicWeb schema for representing Diseasome data.

[dataimport] Slight message modification in exception handling code.

[dataimport] Handle various data formats when creating buffers from data. :note: On the long run, this should be addressed before, when these data are created.

[dataimport] Add a ``flush`` method for all stores. For ``ObjectStore``, ``RQLObjectStore`` and ``NoHookRQLObjectStore`` the method tries to call the ``commit`` method. For ``SQLGenObjectStore``, the ``flush`` method is basically unchanged with respect to previous changesets.

[dataimport] Uniformize the API across the different stores. This is achieved by modifying the ``relate`` method so that it takes an extra ``**kwargs``. More specifically, ``SQLGenObjectStore``'s ``relate`` method needs the the type of the subject entity which is passed through ``**kwargs`` as the ``subjtype`` keyword argument. Actually, it is the ``add_relation`` method of the ``SQLGenObjectStore`` who needs this argument. However, as this method is not called directly (but via the ``relate`` method), the ``subjtype`` argument is passed to ``add_relation`` via ``relate``. The other stores' ``relate`` methods do not need this extra argument, hence for the other stores ``**kwargs`` is empty. In this manner, the API is unified across the different stores.

[data] Add a CSS for undo UI rendering The nesting of ordered list and unordered list was badly handled. This has gone unoticed becaused it was not used. But the undo feature use this markup to render the changesets. That's why this minor change to ths CSS is introduced.

[web/views] extract cube geocoding (closes #353000)

[c-c list] add an optional argument to the list command (closes #2709703) This optional argument allows to restrict listing to only a given type of items (cubes, instances, configurations).

default base-url now uses fdqn instead of hostname only (closes #2542815)

[editcontroller] a small debugging help (closes #2518980)

[doc] small doc improvement

[doc] fix Pyro url

[doc] fix Narval project url

[tutorial] minor documentation fixes

server/source/native: fix wrong usage of .lstrip that produce garbled error messages (closes #2777641) Fixed an .rstrip(...) for the general case (untested). Fixed an .lstrip(...) for the sqlite path (tested).

[doc] update 3.17 release note

[migration] fix bug in `CWAttributeAddOp.revertprecommit_event` The `rdefdef` attribute is set during the operation execution. In some the operation crash before this assignment. In such case `revertprecommit` raise an attribute error crashing the whole process and shadowing the original error. This changeset detect and Avoid this situation.

[session] security context directly use transaction object when applicable Most of the security logic have been moved on Transaction anyway.

[session] move context manager logic in the security context manager The `init_security` and `reset_security` method have no other user that the context manager itself. Having dedicated public function is not useful.

[session] hook control context directly use transaction object when applicable Most of the hooks control logic have been moved on Transaction anyway.

[session] move context manager logic in the hook controls context manager The `init_hooks_mode_categories` and `reset_hooks_mode_categories` have no other user that the context manager itself. Having dedicated public function is not useful.

[session] drop the useless set_hooks_mode method It has not external user and trivial code

[session/transaction] move most undo support into transaction A small part that need repo access has not been moved into transaction yet.

[session] simplify mode property We can delegate very thing to transaction utility

[session/transaction] pass the session object to the Transaction __init__ This simplify access to variables. As we are moving more and more logic and states in the Transaction it will greatly helps in future commit.

[session] use a dedicated class to track cnxset We introduce a new CnxSetTracker to track `cnxset` used by Transaction and allows to wait for them. This new class does not use Thread ID not thread joining to work. This allows to use multiple transaction per thread and a transaction in multiple thread. The class itself is totally threadsafe by the Transaction is still not thread safe. The old _threads_in_transaction attribute is dropped in favor of a new logic based on this object. The registration of cnxset used is not done by the Transaction itself. tx.cnset is a property handling the Consistency of its value with the CnxSetTracker instance. Note: The CnxSetTracker instance only track transaction id, not transaction itself, So not reference cycle are created.

[session] cleanup Transaction.cnxset The attribute should always be there. It is None when not cnxset exists.

[session] drop useless getter and setter for security Those function have very few user and does not anything fancy. Internal user now access tx.read/write_security directly. External user have been blessed with a writable property. They are only interested in the write part of they did not used the return of the removed function. They access it through the session since I prefer the external world to not be aware of Transaction yet.

[session/transaction] move read_security subtlety in transaction This is transaction data, itshould be handled by the transaction itself.

[transaction] initialize dbapi_request in __init__ There is not reason to have it implicitly declared. The attribute is renamed to match its public name.

[transaction] use set operation in the hook control code We use direct operator on set instead of looping by hand, This simplify the codes.

[session/transaction] move hook management in transaction itself This is transaction level code.

[session] allow writable tx_attr and use it for commit_state This keep clarifying the code.

[session/transaction] move add operation in session code

[session/transaction] move entity life utility on transaction This access transaction related data and therefor should live in transaction.

[transaction] small simplification in ecache code A single assignation is simpler.

[session/transaction] move entity cache management on session A new utility method is added for that. It is similar to the one used for attribute access. code is copy pasted as his. Function documentation is added.

[session] have a nice helper function to forward access to session This allows a lighter and clearer code. This will also ease the addition of deprecation warning in the future.

[session] drop dead code session._tx is never None. New transaction are created if necessary.

[session] use tx.data directly in session code.

[transaction] rename transaction_data to data Transaction.transaction_data is redundant. A transaction_data property is left for backward compatibility. Deprecation mechanism will come in later changeset

[session] document Session._tx

[session] split session creation from default session assignation This is the first step for more independence for Transaction.

[session] make session lock reentrant We are going to use it for other session related business. It is renamed from _closed_lock to _lock in the same move.

[session] document set_tx

[session] rename txstore variable to tx This is a more accurate name

[session] rename `_threaddata` to `_tx` The returned object is a Transaction object.

[session] rename self.__threaddata.txdata to self.__threaddata.tx This is Transaction object now.

[session] rename _tx_data into _txs The object inside are now Transaction object. Not TransactionData object.

[transaction] relocate method building transaction context manager It is in the middle of methods going to be refactored.

[transaction] move RQLRewriter in Transaction This remove the last ``AttributeError`` magic. The ``RQLRewriter`` needs a Session. Its reset is handled in ``Session`` code to handle that

[transaction] initialize security control attribute in Transaction There is no reason to not initialize them in __init__ time. This simplify the Session code.

[session] move security constant out of the class There is no reason for it to not be global. This will ease it use by ``Transaction object``.

[transaction] initialize hook control attribute in Transaction There is no reason to not initialize them in __init__ time. this simplify the transaction code.

[session] Move hook control constants out of the class There is no reason for them to not be global. This will ease they use by Transaction object.

[transaction] initialize transaction data and state related attribute. There is not reason to not explicitly declare and initialize attribute in Transaction.__init__. This change requires the introduction of a Transaction.clear() method to get ride of some wicked ``AttributeError`` based logic.

[transaction] handle ``mode`` default value in Transaction The transaction mode is now explicitly passed at creation time and always read from the Transaction object. Note that there is a slight behavior change. The transaction mode is now set at the creation of the transaction. Changes made to the default value have no longer any effect on existing transaction.

[transaction] explicit Transaction cnxset attribute The Transaction object have a lot more attribute that those previously declared in __init__. They are just dynamically assigned in Session code. This changeset explicit the ``cnxset`` and ``mode`` attribute declaration.

[server] rename TransactionData to Transaction Transaction will become a full featured object.
