* Use sessionmaker instead of context block
Essentially there were two bugs:
1) The logging lines before explicit `Session.begin` caused the root
"A transaction is already begun on this Session.", which is
resolved by moving the logging within the explicit session block,
as intended.
2) We were reusing a Session across cron runs. The architecture was
intended to not do so, but we didn't have an actual sessionmaker
available to cron. We probably ought to get rid of scoped_session
elsewhere, but baby steps to resolve the immediate issue.
In testing, this works correctly with the fix to `db.begin`, and
tests with deliberately reintroducing the logging bug, the changes
to session creation prevent the every-15sec stack trace spam.

* Guarantees that the flask db upgrade happens before cron starts
* De-duplicates upgrade logic
* Provides a convenient place to put more startup steps
Investigation of why `@tyre_inflator` didn't appear to ping
`@Tyre_Inflator` revealed that the alerts/notifications system is
correctly case-insensitive. However, the logic in `sanitize` that
converts `@mention`s into user profile links was case-sensitive.
We resolve that here the naive way by normalizing case while comparing.
In some cases, #535 caused comment display to wildly break visible
page formatting. The sidebar often moved to bottom of page, and some
comments would display in a second column alongside the main one.
Root cause was a closing `</div>` left outside of a conditional
which was included in rendered markup even when:
1) A comment is invisible for the current browsing user v, e.g.
filtered or removed.
2) The subtree rooted at said comment is to be hidden based on
the display logic added in #535.
Which left a stray `</div>` with no opening tag where those
comments should've gone.
Most of the testing appears to have been done on reply chains of
comments, which behave correctly. It is specifically the zero
children (or otherwise not even showing a "Removed" message in the
page) which causes the bug.

b46ada9f72 added support for dotenv files to be loaded in lieu of
actual environment variables. This code has since been neglected across
infrastructure changes that removed the need for an env file, moved
its location, and changed dependency management style.
This won't be operative in production (and already isn't, since there'd
be an ImportError on 'dotenv' if so) but makes some local testing
setups more convenient.
* leaderboard: correct LB set when !ENABLE_SERVICES
* leaderboard: fix NotImplementedError
UserBlockLeaderboard did not, in fact, implement `value_func`. Nor did
its superclass. The bug was replicated by having at least one UserBlock
in the test data.
* prepare codebase to create scheduled tasks
there is some prep work involved with this. the scheduler would be happy
if this work was done. simply, we extract out the `created_utc`
interface from *everything* that uses it such that we don't have to
repeat ourselves a bunch. all fun stuff.
next commit is the meat of it.

Two bugs here:
- RepeatableTask.run_time_last <= now: run_time_last is NULL by
default. NULL is not greater than, less than, or equal to any
value. We use NULL to signify a never-run task; check for that
condition when building the task list.
- `6 <= weekday <= 0`: there is no integer that is both gte 6 and
lte 0. This was always false.

* Broad review pass
Review:
- Call `invalidate_cache` with `is_html=` explicitly for clarity,
rather than a bare boolean in the call args.
- Remove `marseys_const*` and associated stateful const system:
the implementation was good if we needed them, but TheMotte
doesn't use emoji, and a greenfield emoji system would likely
not keep those darned lists floating in thread-local scope.
Also they were only needed for goldens and random emoji, which
are fairly non-central features.
- Get `os.environ` fully out of the templates by using the new
constants we already have in files.helpers.config.environment.
- Given files.routes.posts cleanup,get rid of shop discount dict.
It's already a mapping of badge IDs to discounts for badges that
likely won't continue to exist (if they even do at present).
- RepeatableTaskRun.exception: use `@property.setter` instead of
overriding `__setattr__`.
Fix:
- Welcome message literal contained an indented Markdown code block.
- Condition to show "View source" button changed to show source to
logged out. This may well be a desirable change, but it's not
clearly intended here.
* Fix couple of routing issues
* fix 400 with post body editing
* Add error handler for HTTP 415
* fix router giving wrong arg name to handler
* Use supervisord to monitor memory rather than DIY
Also means we're using pip for getting supervisord now, so we don't rely
on the Debian image base for any packages.
* fix task run elapsed time display
* formatting and removing redundant code
* Fix missing ModAction import
* dates and times fixes
* Having to modify imports here anyway, might as
well change it.
* correct documentation.
* don't use urlunparse
* validators: import sanitize instead of from syntax
* cron: prevent races on task running
RepeatableTask.run_state_enum acts as the mutex on repeatable tasks.
Previously, the list of tasks to run was acquired before individually
locking each task. However, there was a period where the table is both
unlocked and the tasks are in state WAITING between those points.
This could potentially have led to two 'cron' processes each running the
same task simultaneously. Instead, we check for runnability both when
building the preliminary list and when mutexing the task via run state
in the database.
Also:
- g.db and the cron db object are both instances of `Session`, not
`scoped_session` because they are obtained from
`scoped_session.__call__`, which acts as a `Session` factory.
Propagate this to the type hints.
- Sort order of task run submissions so /tasks/scheduled_posts/<id>
"Previous Task Runs" listings are useful.
* Notify followers on post publication
This was old behavior lost in the refactoring of the submit endpoint.
Also fix an AttributeError in `Follow.__repr__` which carried over
from all the repr copypasta.
* Fix image attachment
Any check for `file.content_length` relies on browsers sending
Content-Length headers with the request. It seems that few actually do.
The pre-refactor approach was to check for truthiness, which excludes
both None and the strange empty strings that we seem to get in absence
of a file upload. We return to doing so.

PR #547 introduced a UI bug where the comment score tooltip would
show the wrong values (and in fact, the displayed score was also
wrong, though this was not originally noticed).
Specifically, a comment with e.g. +4 | -1 would display in the tooltip
as being +4 | -4 and display a score of 4. The desired behavior would
be +4 | -1 and score of 3. Precisely, the upvote value was displayed
for each of upvotes, downvotes, and net score.
Root cause was the `@lazy` decorator at:
`files.classes.comment._score_context_str(⋅)`
`@lazy` is very dumb. I don't entirely know why we don't just use
`functools.cache`, but we use `@lazy` everywhere. It is entirely
ignorant of the parameters to a function--not a substitute for
memoization.
comments.html contains the following snippet:
{%- set ups = c.upvotes_str(render_ctx) -%}
{%- set score = c.score_str(render_ctx) -%}
{%- set downs = c.downvotes_str(render_ctx) -%}
Each of those three functions internally calls to `_score_context_str`
but with different arguments. The first call to upvotes gets cached by
`@lazy` and the two subsequent calls get the upvotes string, rather than
what they wanted. It's a cheap enough operation that it's not really
worth memoizing, so we just remove the decorator.
