[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

[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.
