* 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.
* cron: basic backend work for scheduler
* avoid ipmort loop
* attempt 2 at fixing import loops
* parathensize because operator precedence
* delete file that came back for some reason.
* does NOPing the oauth apps work?
* import late and undo clients.py change
* stringify column names.
* reorder imports.
* remove task reference
* fix missing mapper object
* make coupled to repeatabletask i guess

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.

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.
Using the new assetcache module, we replace (almost) all instances
of `?v=` cachebusting query parameters in Python and in Jinja templates.
The primary exceptions were: user site backgrounds, and some
infrequently changed graphics referenced literally from .js files.
I created a new theme, "TheMotte" in /assests/css. Someone with any design
skill at all should try improving this. Currently it is a copy of light.css
__main__.py defines the experience for a user without an account. I removed the
check for an OS environment variable, and defaulted to the new theme.
/classes/user.py defines the default for a new account. I removed the check for an OS
environment variable, and defaulted to the new theme.
/routes/settings.py has a list of the themes that checks them for... something.
I added the new one here, just in case.
/templates/settings_profile.html has a hardcoded list that controls which
themes appear in the user settings page. Added the new theme here, so you can
select it.
