This change adds support for displaying inline open graph previews for
links posted into Zulip.
It is designed to interact correctly with message editing.
This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.
By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.
Eventually, we may want to make this manageable via a (set of?)
per-realm settings. E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
While I was setting up the dev environment, pip failed to install
python-twitter: https://github.com/bear/python-twitter/issues/406
This was fixed by manually installing pytest-runner before trying to
install python-twitter, for both the python and python3 virtualenvs.
We set this up initially with all of the rules that Zulip violates
disabled.
Also, the pep8 linter is substantially slower than the other Zulip
linters, so we've put it behind an option to `tools/lint-all`.
This adds a couple new tools that can be used to determine whether a
particular change in Zulip's backend markdown processor would impact
the rendering of historical messages, without a human actually looking
at the message content. This is a useful way to verify whether a
change to our markdown syntax is likely to create problems.
[commit message and code tweaked by tabbott]
- Use tornado as proxy server for development environment,
replacing twisted (this doesn't support websockets).
- Upgrade tornado version to 4.4.1 (needs to be coupled to the
above since neither change works without the other)
- Add scrapy project with rewrited 'crawl' command and spider to check documentation.
Command was rewrited due to return exit status by the exception existing,
it returns exit code 0 if exception happens inside spider in standard behavour.
- Add scrapy requirements to for dev environment. It was added to twisted requirements list.
Fixes#1492
This updates Bugdown to reflect the changes in the updated
markdown. In particular, we now pass a default config object in the
__init__ for the Bugdown extension, update the make_md_engine function
to take kwargs as opposed to a config list, and have UListProcessor
inherit from ulist as opposed to olist (which no longer works).
We update the (forked from upstream) fenced_code extension's
makeExtension to take args and kwargs, and update
FencedBlockPreprocessor __init__ method with updated Codehilite
arguments.
We update the (forked from upstream) Codehilite extension to
mirror the logic with the latest upstream Codehilite:
Add parse_hl_lines function
update makeExtension to take args and kwarfs instead of config
list
Add regex for highlight lines
use linenums instead of linenos
use get_formatter_by_name instead of HtmlFormatter
user get_lexer_by_name instead of TextLexer
add hl_lines and use_pygments arguments to the codehlite
constructor
This reverts commit de5b6d9e37.
This change appears to have caused problems provisioning due to a
conflict with the `--install-option` feature used by talon.
- All necessary strings was converted to bytestring
- Added twisted as py3 dependency
- Change type annotation for method getchild of class Resource
- Remove activating python2 env section from run-dev.py script
Fixes#1256
This adds a new system for copying packages from old virtualenvs that
are sufficiently similar to the new virtualenv required.
In practice, this results in a huge performance improvement for
re-provisioning Zulip development environments when the requirements
files have changed (which is the dominant performance problem with
provision today).
Fixes: #1507.
In HTML, the line break immediately following a start tag is ignored
(see: https://www.w3.org/TR/html4/appendix/notes.html#h-B.3.1). An
extra span tag has been introduced in the upstream Pygments
HtmlFormatter in order to preserve the first new line. The Bugdown
Tests as well as our fenced_code.js frontend markdown processor have
been updated to reflect this new behavior.
This hasn't been used since before Zulip was open source, and isn't
super reusable, so we can remove it. It'll always be there in the
history if someone ends up wanting it.
While we're at it, we remove the GitPython dependency (only used for
this tool) and the example MSMTP config for the review tool.
We install service-identity to prevent twisted from giving spammy
warnings. However, we don't need the security features provided
by service-identity. So we can remove most of its cryptographic
dependencies.
Since twisted is only used for running tools/run-dev.py, we only
need it in development. Also twisted is not python 3 compatible.
So it should be shifter to requirements/py2_dev.txt.
Upgrade alabaster and sphinx to latest version.
commonmark can't be updated because recommonmark uses an old
version of commonmark which is incompatible with latest version.
