db1f578f26 simplify visibility states using the new visstates
because of #606, we now have a relatively decent way of representing
how post/comment state is in the database. we'll use this in our code
which is used to determine what is shown in the UI

6fde14a92c Use reddit-style notifs without context
The notifications schema is already set up for reddit-style
chronological notifications. We simply have to remove the logic that
builds the context and patch up a few places in the frontend that
were expecting full reply trees.

`Comment.header_msg` previously expected the user's own comment to
be top-level in comment replies. Logic is revised to expect the actual
reply.

`files.routes.front.notifications_main` now has reduced query volume
because we aren't expiring the session when marking notifications read.
This also allows us to remove the unused `comms` variable, which is a
makeshift "pattern" of storing duplicate database replies across a
commit so the templates don't requery (thus losing data attached to
the runtime object, like `c.unread` / `c.notif_utc`).

We move the `is_notification_page` flag to the route callers rather
than templates checking `request.path`.

Minor UI style: "Clear all notifications" -> "Mark All Read", since
this was a persistent point of user confusion upstream, with people
expecting their inbox to empty out. Also less margin between notifs
to be consistent with tighter comment display elsewhere and removed
need to separate groups of comments vs single comments.

post scheduling (#554)
* 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.

* Fix logic errors blocking scheduled posts

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.

* pasthrough worker process STDOUT and STDERR

* task runs.

* fix submit page

* add alembic migration

* log on startup

* Fix showing edit button

* Fix logic for `can_edit` (accidentally did `author_id` instead of `id`)

* 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.

79b49342ba Fix: Generating permalinks for comments 500's if the associated post isn't loaded. 2023-03-16 11:12:08 -05:00
TLSM
a060f5840c fix: comment score regression
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.

9895fa1bba comments.html: refactor so that something can be sanely
changed in it

the comments.html template (along with submission.html) has numerous
undesirable properties which i will describe now. unless you are very
familiar with the codebase, it can be extremely difficult to grok.

this is pretty insane as there is nothing fundamentally complex about
the goal of comments.html: return a component that shows a username
and info, reports if any, comment content, and actions a user can
take.

this behemeoth was initially 886 lines in the old version of this
codebase, and this is with awards and a lot of other cruft removed.
anyway, the maintainability of this file is about on par with some
legacy application that keels over and dies if you sneeze vaguely
in its direction.

the nicest thing i can say about it is that it isn't currently
crashing.

anyway some of the problems include:

* large, splittable components, are not split into separate files.

this makes it incredibly difficult to find or make changes across
the template and makes it nearly impossible to find or change a
specific thing.

this is most easily exemplified in the modals, which should by all
accounts be separate templates, just inlined into comments.html.

* the nesting is oftentimes incorrect.

inexplicably, probably out of laziness from when the code was first
written, things will end up fully left aligned, while multiple layers
deep into a nesting context.

if an if statement or an endif is changed, it is *incredibly*
difficult to figure out where the error was. you can't trust the
nesting.

* multiple repeated checks for things that are always true.

this is probably a symptom of the above two problems but it's very
noticeable once you fix the nesting. for example there is a block
near the very top of the actions bar which checks for
parent_submission which effectively checks "is this in a post" (this
commit won't complain about parent_submission checks but i do have
opinions on those).

all of the action buttons further down the chain also check for
parent_submission, or even check inconsistently (by using if c.post)
within this context this is a completely unnecessary check in this
context.

while it is potentially useful (and in fact because #251 requires we
dismantle the assumption a little bit) to have these checks now, the
fact that they were initially added shows that when the code was all
initial written, there was little care into thinking about comment
state.

* mobile actions are duplicated and duplicated inline.

i actually do find it probably pretty hard to support this normally
given the codebase's DOM so whatever, duplicate the things, *but* if
we're going to do that, inlining it into the middle of an incredibly
long template is really difficult to comprehend as a design decision.

...anyway yeah this PR intends to fix these problems and enable work
to be done on #251. this is a "perfect is the enemy of good" commit.
it doesn't change much fundamental and is not intended to erase the
sins of the original file, but at least make it maintainable.

this also fixes a minor bug with #473 where the GIF modal was left
in by accident.

Bug accidentally introduced with 70c8a942b6, when a removed clause

Original intent of the logic was for auto-collapsing game comments
like blackjack and slots that necessarily entailed somewhat spammy

dbaf0a1bfd Remove unused polls code to reduce query volume.
Due to use of Submission.{choices, options, bet_options} in realbody,
generating submission_listings resulted in extremely high volume of
SELECT queries.

In local testing with 6 posts, one of which had a poll with 2 options,
the removal of these calls reduced quantity of queries on the homepage
from 84 to 22.

Given that it was previously decided to remove the polls feature after
a regression while adding comment filtering, the remaining dead code
paths for polls were also removed.

e12b0eea1a Remove treasure rewards for comments.
Given that coins are not visible in many contexts, the conspicuous
appearance of treasure chests (random coin rewards on 1% of comments)
seems out of place. This removes the logic which rewards treasure,
the visible display of treasure, and drops the column containing
treasure information which has already been awarded to at least one
comment on prod.

965a4dc157 Fix improper calls to Comment.replies.
In four contexts, Comment.replies(.) was not updated to reflect the
interface changes with comment filtering. This directly caused #170
and #172 (which was a stack trace from the former).
  - Updating notifications for DMs (routes/users.py L690)
  - Updating notifications for modmail (routes/users.py L729)
  - morecomments for logged out users (routes/posts.py L421)
  - JSON for API access (classes/comment.py L347)

All four contexts seem to behave correctly after the change. However,
strictly speaking the JSON generation will not include a user's own
filtered or removed comments, though this is hard to remedy without
passing the user object `v` to json_core. Propagating that through the
codebase seems a worse option than leaving it as is.
