This feature should hopefully be pretty straightforward. We simply
examine some query string arguments to feed into the diff options.
The function to obtain the diff options has been factored into its
own generic function to facilitate an upcoming change to the HTML
interface and to enable diff settings to be controlled via the same
query string arguments on other web commands.
The test output for "ignoreblanklines" didn't change. I'm not sure
why. Our test coverage for --ignore-blank-lines isn't great and I
can't figure out how to make this diff setting do anything meaningful.
On a very brief examination of the code, it is possible the setting
doesn't work because it is operating at the line level and blank lines
detection needs to examine multiple lines. But I'm not an expert in
this code, so I'm not sure.

This is probably only used in the 'unbundle' command, but the code
ended up being cleaner to make it generic and treat *all* httppostargs
with a non-args request body as though they were file-like in
nature. It also means we get test coverage more or less for free. A
previous version of this change didn't use io.BytesIO, and it was a
lot more complicated.
This also fixes a server-side bug, so anyone using httppostargs should
update all of their servers to this revision or later *before* this
gets to their clients, otherwise servers will hang trying to over-read
the POST body.

The repo instance is currently only used to provide a changeset
lookup function as part of parsing revsets. I /think/ this allows
node fragments to resolve. I'm not sure why we wouldn't want this
to always "just work" if parsing a revset string.
Plus, an upcoming commit will introduce a new consumer that needs a
handle on the repo. So passing it more often will make that code
work more.
Passing a repo instance in all callers of revset.match* results in
a bunch of test changes. Notably, branch and tags caches get
populated as part of evaluating revsets. I'm not sure if this is
desirable. So this patch takes the conservative approach and only
passes the repo if we're passing a ui instance.

Add the followlines.js script and corresponding parameters as data attribute
on <tbody class="sourcelines"> element.
Extend CSS rules so that they also match the DOM structure of annotate view.
As previously, only address paper and gitweb styles (other styles do not have
followlines at all).
context.py seems not a good place to host these functions.

It seems sufficiently simple to use "profile(enabled=X)" to not justify having
a dedicated context manager just to read the config.
(I do not have a too strong opinion about this).
When on a filelog head, we are certain that there will be no descendant so the
target of the "descending" link will lead to an empty log result. Do not
display the link in this case.
When this "descend" query parameter is present along with "linerange"
parameter, we get revisions following line range in descending order. The
parameter has no effect without "linerange".
A common exploit in web applications that access paths is to insert
path separator strings like ".." to try to get the server to serve up
files it shouldn't.
We have code for detecting this in staticfile(). A subsequent commit
will need to perform this test as well. Since this is security code,
let's factor the check so we don't have to reinvent the wheel.
When "patch" query parameter is present in requests to filelog view, line ids
in patches diff are no longer unique in the page since several patches are
shown on the same page. We now prefix line id by changeset shortnode when
several patches are displayed in the same page to have unique line ids
overall.
The previous clause for filter out a diff hunk was too restrictive. We need to
consider the following cases (assuming linerange=(lb, ub) and the @s2,l2
hunkrange):
<-(s2)--------(s2+l2)->
<-(lb)---(ub)->
<-(lb)---(ub)->
<-(lb)---(ub)->
previously on the first and last situations were considered.
In test-hgweb-filelog.t, add a couple of lines at the beginning of file "b" so
that the line range we will follow does not start at the beginning of file.
This covers the change in aforementioned diff hunk filter clause.
This is used to filter out hunks based on their range (with respect to 'node2'
for patch.diffhunks() call, i.e. 'ctx' for webutil.diffs()).
This is the simplest way to filter diff hunks, here done on server side. Later
on, it might be interesting to perform this filtering on client side and
expose a "toggle" action to alternate between full and filtered diff.
We now handle a "linerange" URL query parameter to filter filelog using
a logic similar to followlines() revset.
The URL syntax is: log/<rev>/<file>?linerange=<fromline>:<toline>
As a result, filelog entries only consists of revision changing specified
line range.
The linerange information is propagated to "more"/"less" navigation links but
not to numeric navigation links as this would apparently require a dedicated
"revnav" class.
Only update the "paper" template in this patch.
Add support for a "patch" query parameter in filelog web command similar to
--patch option of `hg log` to display the diff of each changeset in the table
of revisions. The diff text is displayed in a dedicated row of the table that
follows the existing one for each entry and spans over all columns. Only
update "paper" template in this patch.
There's apparently no reason to have the "parity" of diff blocks that
webutil.diffs() generates coming from outside the function. So have it
internally managed. We thus now pass a "web" object to webutil.diffs() to get
access to both "repo" and "stripecount" attribute.
This is useful for when repositories are nested in --web-conf, and in the future
with hosted subrepositories. The previous behavior was only to render an index
at each virtual directory. There is now an explicit 'index' child for each
virtual directory. The name was suggested by Yuya, for consistency with the
other method names.
Additionally, there is now an explicit 'index' child for every repository
directory with a nested repository somewhere below it. This seems more
consistent with each virtual directory hosting an index, and more discoverable
than to only have an index for a directory that directly hosts a nested
repository. I couldn't figure out how to close the loop and provide one in each
directory without a deeper nested repository, without blocking a committed
'index' file. Keeping that seems better than rendering an empty index.
Changeset 11e325d162fe removed the mutable default value, but did not explicitly
tested for None. Such implicit testing can introduce semantic and performance
issue. We move to an explicit testing for None as recommended by PEP8:

Function patch.diffhunks yields items for a "block" (i.e. a file) as a whole
so take advantage of this to simplify the algorithm and avoid parsing diff
lines to determine whether we're starting a new "block" or not. Thus we drop
to external block counter and rely on diffhunks iterations instead.
We also take advantage of the fact that patch.diffhunks() yields *lines* of
hunks (instead of a string) to avoid building a list that is ''.join-ed into a
string that is then split.
As lines in 'header' returned by patch.diffhunks() have no trailing new line,
we need to insert it ourselves to match template expectations.
