Ideally the character set should be set with the connection, and so this is
exactly what's being done now.
And now the character set code is attempted to be generalised.
The previous approach sent the key values twice, which for large sets is
twice as bad.
As an optional feature of this approach multiGet now allows retrieving tuples
in exact order and amount of the requested key values.
Before now table definitions could define collations only for MariaDB using the
MariaDB's collation names directly.
Now instead definitions get a slightly more abstract collation name syntax, but
only supporting the collations utf8mb4_bin and utf8mb4_unicode_(cs|ci) (wrapped
as utf8_bin, utf8_general_(cs|ci)), because those are the ones that have
practical use for GNU social.
Which also means that on MariaDB the formerly used utf8mb4_general_(cs|ci) have
been superseded by utf8mb4_unicode_(cs|ci), as they are the more modern
replacement.
Introduce collation support on PostgreSQL which results in use of the C (POSIX)
collation as utf8_bin and the und-x-icu collation as utf8_general_cs.
utf8_general_ci is also mapped to und-x-icu, which makes it case-sensitive,
unfortunately.
This adds a requirement for all definitions that have foreign keys to also
require indices for all source (local) attributes mentioned in foreign keys.
MariaDB/MySQL creates indices for source attributes automatically, so this
serves as a way to get rid of those automatic indices and create clean explicit
ones instead.
In PostgreSQL, most of the time, indices on the source are necessary to
decrease performance penalty of foreign keys (like in MariaDB), but they aren't
created automatically, so this serves to remove that difference between
PostgreSQL and MariaDB.
Instead of relying on the MariaDB's ON UPDATE CURRENT_TIMESTAMP trigger update
"modified" attributes in Managed_DataObject. Every raw query that needs
adjusting is adjusted, as they won't update "modified" automatically anymore.
The main goal behind this change is to fix "modified" updates on PostgreSQL.
Password hashes are now stored in a TEXT attribute, not limited to 199 symbols.
That limitation makes no sense as password hashes are not the kind of
information to be indexed.
Actually replace crypt() with password_verify() for password checking, current
code left password_verify() unused.
Only update passwords when they use a different algorithm from the current
default. Previously "overwrite" meant rehashing every login.
Replace the "argon" boolean option with "algorithm" and "algorithm_options" for
better configurability.
The default remains whichever is default for PHP's password_hash.
This way UNKNOWN (NULL) explicitly turns to FALSE when three-valued logic is
reduced to binary.
In pgsqlschema, however, use "IS FALSE" as boolean attributes in pg_index are
non-nullable, there is no outer join and there's no clear preference for NULL
reduction.
Over-complicated constructions in TagCloud queries have been simplified, which
should not affect their performance.
Additionally, in TagCloud's lib/subscriptionspeopleselftagcloudsection.php
a typing mistake in an equi-join of "profile_tag" and "profile_list" on
"tagger" was fixed.
That regression was introduced in f446db8e2a
After adding a verb condition there, MariaDB now prefers the
("created", "id", "is_local") and ("profile_id", "verb", "created", "id")
indices for that query, even though they are slow for the job.
So replace them with ("is_local", "created", "id") and
("profile_id", "verb", "created", "id") respectively.
Also fix the naming of the ("profile_id", "created", "id") index.
Avoid the use of deprecated MariaDB "zero dates" globally. If they're present
as attribute defaults somewhere, they will be replaced with NULL implicitly.
The existing "zero dates" in MariaDB storage will be left intact and this
should not present any issues.
The "timestamp" type in table definitions now corresponds to DATETIME in
MariaDB with "DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP", which
should be close enough to the original behaviour for compatibility purposes.
It is now the recommended type for "modified" attributes, because of the
update trigger on MariaDB. But there is no such trigger implemented on
PostgreSQL as of this moment.
On big databases these queries from the Nodeinfo plugin choked up:
SELECT profile_id FROM notice
WHERE notice.created >= (CURRENT_DATE - INTERVAL '180' DAY)
AND notice.is_local = 1;
SELECT id FROM "user"
WHERE "user".created >= (CURRENT_DATE - INTERVAL '180' DAY);
Use $object->sqlValue('NULL') (identical to DataObject_Cast'ing) instead and
fix related issues like (email|sms)settings considering these NULLs as a
false positive for the E-Mail address still being set when it's been removed.
There could also be security implications to the now-disabled approach of
considering 'NULL' strings as SQL NULLs.
