[tests/web] switch previous commit (136b5f995f8) to the new test api Related to #3670209.

[web] remove unused argument from treeview._init_headers

[doc/3.20] mention CWEP-002

[web] stop accepting the magic __message form parameter This has been deprecated for a while, and replaced by _cwmsgid, which doesn't allow arbitrary content.

[web/request] add security_enabled method Just forward to the underlying repo connection. This can be useful in the ORM when dealing with a "code-only" attribute, i.e. something that shouldn't be directly user-visible but must be accessible from a web request.

[dataimport] Fix use of _create_copyfrom_buffer() (related to #3845572) This is used indirectly by SQLGenObjectStore when running on a PostgreSQL database. Regression introduced by commit 70056633085c.

[c-c configure] make it possible to specify the section for sources configuration (closes #3477678)

[server] fix 'cnx' variable confusion in DBG_SQL exception case The rollback handling expects 'cnx' to be the cubicweb Connection, but the DBG_SQL block was replacing it with an sql connection, leading to lulz down the line. Also remove obsolete getattr (the sqlite wrapping is now done at the cnxset level, so cnx.cnxset.cnx should be the right thing already).

Provide sufficient context to check 'delete' permission in AjaxEditRelationCtxComponent Call rdef.check only when both fromeid and toeid are available. Though only call it once (for the first encountered related entity). Factorize a bit to keep handling of CSS/JS addition the same. Closes #3670209.

merge 3.19.6 into 3.20 branch

Added tag cubicweb-version-3.19.6, cubicweb-debian-version-3.19.6-1, cubicweb-centos-version-3.19.6-1 for changeset 934341b848a6

[test] missing unittest.main() call in unittest_http_headers.py

[test] make unittest_webconfig independant of CWD if apphome is unset in ApptestConfiguration constructor, this later looks for a 'data' directory in CWD, making this test runnable only from web/test (and pytest do chdir before executing tests, so we did not noticed this problem).

[webctl] do not ask questions if verbosity is at 0 Closes #4641960.

[web] Slight tweak on jQueryUI's colors on links (related to #4564046) Follow up to commit 16f550b48d57 which was somewhat brutal. This change only overrides jQueryUI's CSS rules inside tab panes and leaves actual tab buttons alone.

[view] Remove unused imports

Remove obsolete __future__ imports Generators have been available since 2.3, "with" statements since 2.6.

[devtools] Remove unused local function Unused since cw's first commit.

[uihelper] Fix a possible NameError in meta_formconfig could occur when using FormConfig with a custom uicfg object. Closes #3802298.

[devtools] Avoid db_cache collisions and mis-loading This is done by stopping to share the db_cache between TestDataBaseHandler instances It may seem overkill, but is the only way I could get it to work properly. I think the whole db caching code needs some rework to better work with different db handlers. Closes #4601328

[devtools][pg] Remove a wrong assertion in _backup_database When using pre_setup_database, a repo gets initialised before calling backup_database. Hence self._repo is NOT None it that case.

[pkg] prepare 3.19.6

[merge] backport 3.18 fixes

Accept '==' operator in cubes dependencies '==' is the operator used in the python dependencies specifications. See PEP 440 http://legacy.python.org/dev/peps/pep-0440/#version-specifiers Using the same operator in cubes dependencies allow to make setuptools handle the cubes dependencies while keeping cubicweb happy about the dependencies. Closes #4375144

[session] don't silently ignore commits commits while in the precommit or postcommit phase are silently ignored. This is OK in precommit since there'll be a commit afterwards anyway; OTOH in postcommit it may surprise the developer who didn't read the documentation for postcommit operations carefully enough. Related to #4383922.

[migration/bootstrap] add explicit index removal for sqlserver, be tolerant to migration replay Closes #4618944.

Added tag cubicweb-version-3.18.7, cubicweb-debian-version-3.18.7-1, cubicweb-centos-version-3.18.7-1 for changeset cb96f4403cf2

[pkg] prepare 3.18.7

[migration/3.18] speed up the migration and be a little bit more informative Closes #4619277.

[schemaserial] be robust against duplicated CWUniqueTogetherConstrain entities arising from bug in the pre 3.18 era Closes #4619278.

[server] Handle unique constraint violations under recent sqlite The error message changed from "columns foo, bar, baz are not unique" to "UNIQUE constraint failed: table.foo, table.bar, table.baz". Closes #3564510

[merge] backport 3.17 fixes
