Adds 'email' to hiddenuserfields, which allows:
* user to view email on their own profile,
* users with cap site:viewuseridentity to view email on any profile (admins/teachers)
* admin to veto display of email to users without site:viewuseridentity (except viewing their own)
* unprivileged users to view if the profile's maildisplay permits it.
Changes in user/lib.php include removal of is_siteadmin() test, which
is redundant due to checks via has_capability().
Fixes regression from 2.9 (MDL-45774).
Adds a new 'Gradual reindex' link to the search areas page for each
area. When clicked, this takes you to a confirm prompt, and then
adds each context from that search area to the indexing queue.
The search areas page now displays the 'Additional indexing queue'
(if it is non-empty). The table shows the first 10 items in the
queue, and it also indicates the total number in case there are
more. (I don't think people really need to see the entire
contents of it, so I didn't implement paging.)
The patch increases the maximum supported precision (total number of
digits) for numeric (decimal) fields to 38 digits (current limit on
Oracle and MSSQL).
Additionally, we add our own limit for the whole number part of numeric
fields so they are no longer than integer fields (20 digits). This is to
make it easier to eventually convert from one field type to another.
Note that PHP floats commonly support precision of roughly 15 digits
anyway.
Make sure we always checks for failed validation, before redirecting.
A positive return value does not signal that all settings were able
to be written, only that at least one was - errors still need to be
checked!
LTS (3.5) requires previous LTS (3.1)
This just deletes all the upgrade steps previous to 3.1.0. Some
small adjustments, like adding missing MOODLE_INTERNAL or tweaking
globals can also be applied when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2016052300 (v3.1.0) as anti-cheating measure.
Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase.
The new recordset support for Postgres requires transactions and
will cause errors if recordsets are not closed correctly. This
commit fixes problems that were identified during unit tests, and
via some basic code analysis, across all core code. Most of these
are incorrect usage of recordset (forgetting to close them).
