* 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
* sanitize: fix sanitize imports
* import shadowing crap
* re-shadow shadowed variable
* fix regexes
* use the correct not operator
* readd missing commit

let's avoid polluting scopes where we can.
* ...

the master periodically checks to see if the slave is alive, healthy,
and not taking too many resources, and if applicable kills its
child and restarts it.
only one relation is supported at the moment.

* add relationship between task and runs
* fix some ui stuff
* fix incorrect timestamp comparison
* ...
* 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.

* 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.

the random c.sentto == 2 magic numbers in the code is... pretty
unmaintainable and unless you were aware of who "2" was, it's hard to
know what's going on.
in addition, we force modmail to go through the modmail path instead of
letting users bypass validation checks.
Fixes#483. Implement a Jinja template filter to shuffle a sequence
(which surprisingly doesn't already exist) and shuffle the relevant
lists in the sidebar.
The ADMINISTRATORS list contained hardcoded post IDs (in the 30000s)
intended to be used for uploading graphical assets onto a production
instance of the site. This functionality is not needed here, and the
special logic to bypass awards when commenting on those posts was
largely removed in 9d4195a89f.
Borrows code from the upstream which has been working in production
reliably for ~months. Also, most of it was literally copy-pasted,
and the casted ID values aren't used later in the route functions.
Rather than generating the URL in helpers/jinja2.py, we move the logic
to helpers/assetcache.py because there are consumers of asset URLs
in Python code (for better or for worse).
Provides a module `assetcache` to support automatic cachebusting of
static web assets, rather than the current approach of incrementing
a version number.
On module load, it walks the file/assets/ dir, computes a CRC32 of
each asset, and provides those hashes via `assetcache_get(path)` at
runtime. The primary consumer of hashes at present is the new `asset`
filter for Jinja2, which accepts a relative asset path and returns the
full path, with cache busting, suitable for final use in the template.
Ex: `{{ 'css/main.css' | asset }}`
