For unknown reasons the alabaster theme on the docs server is always generating
a GitHub link in the side bar. Beside the privacy problems of having an iframe
to some third-party service, we never configured any GitHub integration so
this button just links to the GitHub main site.
The button generation should be disabled by default, but as that's apparently
not true in the alabaster theme on the server, this patch tries working around
the issue by just explicitly turning off the GitHub integration.
Apparently the sphinx version on the server doesn't place <p> tags in the
table cells, so the previous fix from commit 7fce3b240b
didn't fix the bug for that sphinx version. Just expand the CSS workaround
to all <td> tags.
This patch implements a filter that post-processes some of the generated RST sources
of the Python API docs. I mainly want to avoid two things:
1. Filter out all the inheritance boilerplate that just keeps mentioning for
every class that it inherits from the builtin 'object'. There is no inheritance
in the SB API.
2. More importantly, removes the SWIG generated `thisown` attribute from the
public documentation. I don't think we want users to mess with that attribute
and this is probably causing more confusion than it would help anyone. It also
makes the documentation for some smaller classes more verbose than necessary.
This patch just uses the sphinx event for reading source and removes the parts
that we don't want in documentation.

The tables in the new LLDB documentation currently are less wide than their
contents. The reason for that seems to be the `-webkit-hyphens: auto` property
that sphinx is setting for all `p` tags. The `p` tags in the generated Python
documentation seem to trigger some Safari layout issue, so Safari is calculating
the cell width to be smaller than it should be (which ends up looking like this
{F15104344} ).
This patch just sets that property back to the browser default `manual`. Not
sure if that's the proper workaround, but I clicked around on the website with
the changed CSS and nothing looked funny (which is I believe how webdev unit
testing works).

This is mostly SEO so that the new API can take over the old API when people
search for the different SB* classes. Sadly epydoc decided to throw in a -class
prefix behind all the class file names, so we can't just overwrite the old files
with the newly generated ones.

Enums and constants are currently missing in the new LLDB Python API docs.
In theory we could just let them be autogenerated like the SB API classes, but sadly the generated documentation
suffers from a bunch of problems. Most of these problems come from the way SWIG is representing enums, which is
done by translating every single enum case into its own constant. This has a bunch of nasty effects:
* Because SWIG throws away the enum types, we can't actually reference the enum type itself in the API. Also because automodapi is impossible to script, this can't be fixed in post (at least without running like sed over the output files).
* The lack of enum types also causes that every enum *case* has its own full doc page. Having a full doc page that just shows a single enum case is pointless and it really slows down sphinx.
* There is no SWIG code for the enums, so there is also no place to write documentation strings for them. Also there is no support for copying the doxygen strings (which would be in the wrong format, but better than nothing) for enums (let alone our defines), so we can't really document all this code.
* Because the enum cases are just forwards to the native lldb module (which we mock), automodapi actually takes the `Mock` docstrings and adds it to every single enum case.
I don't see any way to solve this via automodapi or SWIG. The most reasonable way to solve this is IMHO to write a simple Clang tool
that just parses our enum/constant headers and emits an *.rst file that we check in. This way we can do all the LLDB-specific enum case and constant
grouping that we need to make a readable documentation page.
As we're without any real documentation until I get around to write that tool, I wrote a doc page for the enums/constants as a stop gap measure.
Most of this is done by just grepping our enum header and then manually cleaning up all the artifacts and copying the few doc strings we have.

sphinx processes text in backticks depending on what 'role' it has (e.g.,
`:code:\`blub\`` -> role is `code`). If no role is provided, the default role is
taken which is right now using the default value of `content`. `content` only
really makes the text cursive which isn't really useful for anything right now.
Sphinx recommends using the `any` role by default [1] as that turns text in
backticks without an explicit roles into some kind of smart reference. If we did
this in LLDB, then we could just reference SB API classes by doing `\`SBValue\``
instead of typing out the rather verbose `:py:class:`/`:py:func:`/... role
before each reference. This would be especially nice when writing the SB API
docs itself as we constantly have to reference other classes.

Right now we're using the 'content' role as default which will just render
these things as cursive (which isn't really useful for code examples). It also
prevents us from assigning a more useful default role in the future.
The build server should now have the missing dependencies.
Original summary:
Currently LLDB uses epydoc to generate the Python API reference for the website.
epydoc however is unmaintained since more than a decade and no longer works with
Python 3. Also whatever setup we had once for generating the documentation on
the website server no longer seems to work, so the current website documentation
has been stale since more than a year.
This patch replaces epydoc with sphinx and its automodapi plugin that can
generate Python API references. LLVM already uses sphinx for the rest of the
documentation, so this way we are more consistent with the rest of LLVM. The
only new dependency is the automodapi plugin for sphinx.
This patch effectively does the following things:
* Remove the epydoc code.
* Make a new dummy Python API page in our website that just calls the Sphinx
command for generated the API documentation.
* Add a mock _lldb module that is only used when generating the Python API.
This way we don't have to build all of LLDB to generate the API reference.
Some notes:
* The long list of skips is necessary due to boilerplate functions that SWIG
is generating. Sadly automodapi is not really scriptable from what I can see,
so we have to blacklist this stuff manually.
* The .gitignore change because automodapi wants a subfolder of our
documentation directory to place generated documentation files there. The path
is also what is used on the website, so we can't really workaround this
(without copying the whole `docs` dir somewhere else when we build).
* We have to use environment variables to pass our build path to our sphinx
configuration. Sphinx doesn't support passing variables onto that script.

Bump the required SWIG version to 3. If my memory serves me well we last

In a discussion with Jim last week we came to the realization that often
we get asked about things that might not be documented on the website,
but that have been pretty well explained elsewhere. In those situations
it's often easier to quickly answer the question than searching for that
presentation you gave 3 years ago if you remember at all.
This often results in us having to answer the same questions over and
over again. We could add the questions and their answer to the website,
but that means we (1) have to duplicate the work and (2) now have to
maintain it.
A more efficient solution is to add a page with external resources with
the caveat that they might be outdated. That's exactly the purpose of
this patch.

Jim pointed out that "every time somebody has touched the documentation
on startup files they have stated that we source the application one and
then the global one, even though in actual fact we’ve never done that."
Indeed, when we read the application specific .lldbinit file, the global
one is not read. This patch updates the man page to reflect that.
This adds a new target `check-lldb-reproducers` that replaces the old
`check-lldb-repro`. The latter would only run the shell tests, while
`check-lldb-reproducers` includes the API tests as well. The new target
will be used on GreenDragon.
It's still possible to run just the shell tests with reproducers,
although now that requires crafting the lit invocation yourself. The
parameters haven't changed and are the shame for the API and shell
tests:
--param lldb-run-with-repro=capture
--param lldb-run-with-repro=replay
This patch also updates the reproducer documentation.
Before the transition to libOption it was possible to specify arguments
for the inferior without -- as long as they didn't start with a dash.
For example, the following invocations should all behave the same:
$ lldb inferior inferior-arg
$ lldb inferior -- inferior-arg
$ lldb -- inferior inferior-arg
This patch fixes that behavior, documents it and adds a test to cover
the different combinations.

Summary:
The ValueObject code checks for a special `$$dereference$$` synthetic
child to allow formatter providers to implement a natural
dereferencing behavior in `frame variable` for objects like smart
pointers.
This support was broken when used directly throught the Python API and
not trhough `frame variable`. The reason is that
SBFrame.FindVariable() will return by default the synthetic variable
if it exists, while `frame variable` will not do this eagerly. The
code in `ValueObject::Dereference()` accounted for the latter but not
for the former. The fix is trivial. The test change includes
additional covergage for the already-working bahevior as it wasn't
covered by the testsuite before.
This commit also adds a short piece of documentatione explaining that
it is possible (even advisable) to provide this synthetic child
outstide of the range of the normal children.
