Steve Howell 6a5c407b05 user export: Be more selective about exported messages. 2021-12-09 17:20:01 -08:00
Steve Howell fa654fd7a0 user export: Ignore realm icon and logo.
These are not considered to be "personal"
info, even if you upload them, so we
don't export them.

Generally the only folks who upload
these are admins, who can easily get
them in other ways. In fact, anybody
can get these via the app.

Steve Howell 8f991f8eb1 export: Make sure messages are sorted **across** files.
We now ensure that all message ids are sorted BEFORE
we split them into batches.

We now do a few extra "slim" queries to get message
ids up front.

But, now, when we divide them into batches, we no
longer run 2 or 3 different complicated queries in
a loop. We just basically hydrate our message ids,
so `write_message_partials` should be easy to reason
about.

This change also means that for tiny realms with
< 1000 messages you will always have just one
json file, since we aggregate the ids from the
queries before batching.

Steve Howell cef0e11816 export: Add get_id_list_gently_from_database.
This is slightly overkill for the single-user use
case, but for small queries it's barely any overhead,
and it's a nice abstraction.

Steve Howell 8ea320812f user exports: Chunkify messages in sorted order.
This accomplishes a few things:

    * It extracts `chunkify` rather than having us
      clumsily track chunking-related stuff in a
      big loop that is doing other stuff.

    * It makes it so that all message ids
      in message-000001.json < message-000002.json.

    * It makes it easier for us to customize
      the messages we send to a single user
      (coming soon).

BTW we probably have a slicker version of chunkify
somewhere in our codebase, but I couldn't remember
where.

Steve Howell 2a73964e16 user export: Add reactions.
We may eventually try to attach these to the messages
in the message-NNNNNN.json files, but for now they're
fine in user.json.

Steve Howell f810833df5 export: Improve export_usermessages_batch.
We no longer jankily read our input file into

in a type-safe way.

Steve Howell 5c1e8cb8dc mypy: Add MessagePartial TypedDict. 2021-12-09 08:36:40 -08:00
Steve Howell 09c57a3f9f export: Log more consistently and sort ids.
Now all file writes go through our three
helper functions, and we consistently
write a single log message after the file
gets written.

I killed off write_message_exports, since
all but one of its callers can call
write_table_data, which automatically
sorts data.  In particular, our Message
and UserMessage data will now be sorted
by ids.
2021-12-09 08:36:40 -08:00
Steve Howell 6ec49951c6 minor: Avoid creating intermediate list for message_ids.
This probably just postpones the list creation until
Django builds the "IN" query, but semantically it's
good to work in sets where we don't have any
meaningful ordering of the list that gets used.

Steve Howell f8ed099d3c export: Sort table data for most tables.

Steve Howell a1d3f12e53 refactor: Extract write_table_data().
The immediate benefit of this is stronger mypy

We have test coverage on all these lines insofar
as if you comment out the lines, tests will
explode (i.e. more than superficial line
coverage).

Steve Howell 927b04368e minor: Use virtual_parent for custom fetchers.
The distinction here wasn't super meaningful
due to the way we order our "elif" statements,
but we want to reserver "normal_parent" for the
majority of use cases, where you simply tell
the Config what the "foreign_key" is.

2021-12-08 15:58:07 -08:00
Steve Howell 8dd3c1038f exports: Rename parent_key to include_rows.
Even though Django usually treats foo__in
and foo_id__in identically for filters where
foo is a ForeignKey type, we want to insist
on somewhat more consistent syntax, because
we have the odd combo of type and type_id
in Recipient, where type_id is kinda like a
foreign key, but not a ForeignKey.

So we assert for now that all our include_rows
values end in "_id__in".

Steve Howell b0e5c1d3b9 export: Remove paranoid assertion.
There are tactical reasons to remove this assertion.

Basically, the reason it's safe to remove is that it's
been around a long time and we would have seen this
operationally. Also, the check to make sure that the
S3 filename thingy matches the avatar hash is a much
stronger check.

We will soon restore a stronger version of this check
that applies to all of our asset types (emojis/avatars/etc.).

This makes it easier to read the calling code and see
the big picture of how the four asset types are
organized.

I also handle uploads first, to be similar to the local
code.

This code is well tested--you can modify any of the callers
to pass in a wrong value of `object_key` and get a failing
test.

Steve Howell 946e8064a3 user exports: Add several tables to the tarball.
We add the following tables to the user export:

    AlertWord
    CustomProfileFieldValue
    RealmAuditLog
    Service
    UserActivity
    UserActivityInterval
    UserCount
    UserGroup
    UserHotspot
    UserPresence
    UserTopic

Except for UserCount, we achieve this by sharing
code with the realm export via
add_user_profile_child_configs.

UserCount is handled slightly differently than realm
exports due to which key we trigger off.

It's possible that RealmAuditLog is incomplete for
single users, since we may also want rows where they
are the acting_user. This commit finds rows where
they are the modified_user. For non-admins I believe
it's rarely the case that they are the actor, and
they will tend to be the modified user if the two
fields are different at all.  For admins it's
arguable we want to see both changes they enacted
as well as changes that affected them.

sahil839 7d64a9053b models: Ensure every realm has a RealmUserDefault object.
Because we create all realms with do_create_user (including in the

existing realms, and ensure the data import code path correctly
creates these objects.

Note that the import code path will create a RealmUserDefault row with
default values if it is not present in the import data, which is
important for importing data from other tools like Slack.

Mateusz Mandera 1a8ad796f8 models: Replace __id syntax with _id where possible.
model__id syntax implies needing a JOIN on the model table to fetch the
id. That's usually redundant, because the first table in the query
simply has a 'model_id' column, so the id can be fetched directly.
Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.

The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
  y = models.ForeignKey(Y)

then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)

Steve Howell 9662af842f export: Remove stream sanity check.
We also remove the post_process_data option.

The sanity check is just overkill at this point,
since the mechanism to find streams is very
direct due to a recent commit.

Steve Howell 54c596cfc4 export: Just export all streams in a realm.
Before this change we would only export streams
that had actual subscribers, which is usually
harmless, but it was mostly a relic of a one
time migration that we did when we were cleaning
up some dirty data in some of our very early
databases (circa 2016).

Now we work down the table hierarchy in a
more natural way:

    - get Streams in Realm
    - get Recipients matching above Streams
    - get Subscriptions matching above Recipients

Note that for per-user exports, I kept the
same logic (users -> subscriptions -> recipients ->
streams) we had before.

One subtle detail here is that we make our
final Config blocks--which build the final
version of Recipient/Subscription--now hang
off of realm_config.

Fixes #15146.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.

Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start.  I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Graham Bleaney 461d5b1a3e pysa: Introduce sanitizers, models, and inline marking safe.
This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for
extracting user input, and `redirects.pysa` for capturing the risk
of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.

Wyatt Hoodes 5a58b7c549 data exports: Keep deleted export in UI table.
It makes sense to keep a deleted export in the table,
along with the time of deletion, for auditing reasons.

Wyatt Hoodes 82e7ad8e25 data exports: Handle pending and failed exports.
Prior to this change, there were reports of 500s in
production due to `export.extra_data` being a
Nonetype.  This was reproducible using the s3
backend in development when a row was created in
the `RealmAuditLog` table, but the export failed in
the `DeferredWorker`.  This left an entry lying
about that was never updated with an `extra_data`
field.

To fix this, we catch any exceptions in the
`DeferredWorker`, and then update `extra_data` to
encode the failure.  We also fix the fact that we
never updated the export UI table with pending exports.

These changes also negated the use for the somewhat
hacky `clear_success_banner` logic.

Abhishek-Balaji 052368bd3e alert_words: Move alert_words from UserProfile to separate model.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile.  That hacky model reflected the fact that
they were an early prototype feature.

This commit migrates from that to a separate table, 'AlertWord'.  The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).

This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.

Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.

This commit was split by tabbott; this piece covers the vast majority

ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.
