hgweb: add .jshintrc with some basic rules This file is picked up automatically by jshint, so no extra changes required in test-check-jshint.t.

hgweb: look up "URLSearchParams" in "window" to work around jshint issues Unfortunately, current version of jshint (2.9.5) doesn't know such a global variable and complains that it's undefined. Since this line tries to look up URLSearchParams in a global scope (i.e. window), let's simply preface it with "window." to work around jshint.

hgweb: define locally used variables as actually local in mercurial.js Variables that are used or assigned without any declaration using var (or let, or const) are considered global. In many cases this is inadvertent and actually causes a variable leaking to a broader scope, such as a temporary variable used inside a loop suddenly being accessible in global scope. (This corresponds to "undef" option of jshint). So this patch limits the scope of variables that don't need to be global. There are a lot of helper variables in Graph.render() used in a loop, I've declared them all on one line to reduce patch size. "radius" is special because it wasn't passed to graph.vertex, but was used there (it worked because this variable leaked to global scope). "window.graph" is created by an inline script in graph.tmpl so that it can be used in ajaxScrollInit() function, this patch makes this fact explicit by assigning window.graph to a local variable.

hgweb: rename an instance of XMLHttpRequest to xhr in mercurial.js "xhr" is a really widespread name for this kind of things, no idea where did "xfr" come from (the original 2228bd109706 doesn't explain that). Let's just change one letter so the name makes more sense.

hgweb: properly iterate over arrays and objects in mercurial.js In JavaScript, using for-in loops to access every property of an object can have unexpected results when inheritance is involved. For example, if some piece of code adds a property (it may be a method too) to Object.prototype, then all for-in loops that iterate over keys of any object (also anything that inherits Object) will get that property on one of the iterations. To filter out such unexpected properties for-in loops have to use Object.hasOwnProperty() method. (This corresponds to "forin" option of jshint). In the two first cases "data" and "edges" are arrays, to it's simpler to just switch to using a regular for-with-a-counter loop.

hgweb: use strict equals in mercurial.js This patch changes "==" (equals operator) to "===" (strict equals operator). The difference between them is that the latter doesn't do any type coercions. It's handy to compare string '1' to number 1 sometimes, but most of the time using "==" is inadvertent and can be replaced by an explicit type conversion. (This corresponds to "eqeqeq" option of jshint). Some of the changes in this patch are straightforward, e.g. when comparing results of typeof (they could only be strings). The same goes for 'none' and similar strings that can't be sensibly coerced to some other type. Two changes that compare values to "1" and "0" can be clarified: getAttribute() returns either a string or null, but comparing null to a string is always false, so no logic is lost.

hgweb: use strict equals, remove non-breaking space in followlines.js The first hunk had a non-breaking space character just before "{", it's not an error or anything, but let's fix it while we're at it. (This corresponds to "nonbsp" option of jshint). Hunks 2 and 3 change "==" (equals operator) to "===" (strict equals operator). The difference between them is that the latter doesn't do any type coercions. It's handy to compare string '1' to number 1 sometimes, but most of the time using "==" is inadvertent and can be replaced by an explicit type conversion. (This corresponds to "eqeqeq" option of jshint). Most of this file already uses strict equals operator, and in the code affected type coercion is not needed, because tagName and selectableTag are both strings and endId and startId are both numbers.

run-tests: make "| foo (re)" not match everything We make "foo (re)" match the entire line by adding a \Z to the regular expression before matching. However, that doesn't help when the regular expression is something like "| foo", because that gets translated to "| foo\Z", where the "|" has lower precedence and it thus matches the empty string, which is of course a prefix of every string. Fix by wrapping expression in a group before adding the \Z to the end. Differential Revision: https://phab.mercurial-scm.org/D1546

tests: fix regex in test-subrepo-git.t to match entire string Due to a bug in the test runner (fixed by the next commit), the regex used for matching lines like " foobar | 2 +-" stoppped at the "|" and the test passed even though the rest of the line did not match. The test seems to have been supposed to match "|" and "+" literally on those lines, so this changes the regex to escape those characters. It also changes a "\s*" to "\s+" since I think we'll always include a space after the "|" in the diffstat output. Differential Revision: https://phab.mercurial-scm.org/D1545

contrib: improve check-code ban on $LOCALIP in output without (glob) Differential Revision: https://phab.mercurial-scm.org/D1553

tests: re-add (glob) for $LOCALIP matches This should fix most of the failing tests on the FreeBSD builder, since it has no 127/8 series IP as a side effect of being trapped in a jail. Differential Revision: https://phab.mercurial-scm.org/D1552

tests: move JSON escape test to test-hgweb-json.t The original tests (kanji and null) in test-hgweb-commands.t come from aff419e260f9 and 823a7d79ef82, but they check json escape filter by using JavaScript variable on /graph page, which is awkward, and I'm planning to remove commit description from this variable soon. Let's move the parts that check json template filter to a more appropriate file and use normal json-* templates.

test-lfs: allow the test server to be killed on Windows Apparently '$!' doesn't return a Win32 PID, so the process was never killed, and the next run was screwed up. Oddly, without the explicit killdaemons.py at the end, the test seems to hang. This spawning is just sad, so I limited it to Windows.

test-lfs: perform the `chmod +x` command in a manner compatible with Windows

hghave: add a check for lfs-test-server This is consistent with how the other tests require a feature.

hgweb: show changeset age in more places (gitweb and monoblue) mercurial.js has a process_dates() function that calculates relative age for a given date, it works for all elements with "age" css class. If those elements also have "date" css class, the original text is preserved and age is added at the end. This patch adds these two css classes in some pages in gitweb and monoblue that weren't already using this feature.

hgweb: remove unused Graph() properties Both of these were introduced in 0dba955c2636, but were already unused.

gitweb: remove unused css classes Looks like they were unused since the very introduction of gitweb theme in 385b8872b8e3.

monoblue: also highlight target line on annotate and comparison pages Clicking on a line link on pages that show any kind of file contents (including diffs) should highlight that line, and in monoblue it works when there's a <pre> element (e.g. diff), but pages that use <table> element (annotate and compare) need this css class. It matches and highlights linked (":target") table rows. This line is pretty much copied from gitweb theme.
