The computation of roots was buggy, any ancestor of a bundled merge which was

templater: parse \"...\" as string for 2.9.2-3.4 compatibility (issue4733)
As of Mercurial 3.4, there were several syntax rules to process nested
template strings. Unfortunately, they were inconsistent and conflicted
each other.
a. buildmap() rule
- template string is _parsed_ as string, and parsed as template
- <\"> is not allowed in nested template:
{xs % "{f(\"{x}\")}"} -> parse error
- template escaping <\{> is handled consistently:
{xs % "\{x}"} -> escaped
b. _evalifliteral() rule
- template string is _interpreted_ as string, and parsed as template
in crafted environment to avoid double processing of escape sequences
- <\"> is allowed in nested template:
{if(x, "{f(\"{x}\")}")}
- <\{> and escape sequences in string literal in nested template are not
handled well
c. pad() rule
- template string is first interpreted as string, and parsed as template,
which means escape sequences are processed twice
- <\"> is allowed in nested template:
{pad("{xs % \"{x}\"}', 10)}
Because of the issue of template escaping, issue4714, 7298da81f5a9 (in stable)
unified the rule (b) to (a). Then, 576d6c74784b (in default) unified the rule
(c) to (b) = (a). But they disabled the following syntax that was somewhat
considered valid.
{if(rev, "{if(rev, \"{rev}\")}")}
{pad("{files % \"{file}\"}", 10)}
So, this patch introduces \"...\" literal to work around the escaped-quoted
nested template strings. Because this parsing rule exists only for the backward
compatibility, it is designed to copy the behavior of old _evalifliteral() as
possible.
Future patches will introduce a better parsing rule similar to a command
substitution of POSIX shells or a string interpolation of Ruby, where extra
escapes won't be necessary at all.
{pad("{files % "{file}"}", 10)}
~~~~~~~~~~~~~~~~~~
parsed as a template, not as a string
Because <\> character wasn't allowed in a template fragment, this patch won't
introduce more breakages. But the syntax of nested templates are interpreted
differently by people, there might be unknown issues. So if we want, we could
instead remove db7463aa080f, 890845af1ac2 and 7298da81f5a9 from the stable
branch as the bug fixed by these patches existed for longer periods.
554d6fcc3c8, "strip single backslash before quotation mark in quoted template",
should be superseded by this patch. I'll remove it later.

archive: don't assume '.' is being archived for changessincelatesttag
Hardcoding '.' is wrong, and yielded strange results when archiving old
revisions. For example, when archiving the cset that adds the signature to 3.4
(c48850339988), the resulting value was previously 51 (the number of commits on
stable between 3.4 and today), even though it was a direct descendant of a tag,
with a {latesttagdistance} of 2. This still includes all other _ancestor_ paths
not included in {latesttag}.
Note that archiving wdir() currently blows up several lines above this when
building the 'base' variable. Since wdir() isn't documented, ignore that it
needs work to handle wdir() here for now.

hgweb: use css for stripey background in coal
Since "b8ecc3830c89 or 25dae11bb044::c229a5e7511e" paper style used css for
stripes in background for browsing files, for listing branches/tags/bookmarks,
and so on.
Since coal borrows many paper templates (e.g. shortlogentry.tmpl), it actually
tried to do the same, but it didn't have the needed css classes. You can
compare https://selenic.com/hg?style=coal with
https://selenic.com/hg?style=paper and see how log view in coal style has plain
white background, unlike the one in paper style. This wasn't intended.
Let's copy css classes directly from style-paper.css and remove parity classes
from elements that don't need them anymore. This makes plain white background
have stripes again and makes coal/map even more similar to paper/map (which can
ease porting changes or %including paper/map in future).

repair: add functionality to rebuild fncache
Currently, there is no way to recover from a missing or corrupt fncache
file in place (a clone is required). For certain use cases such as
servers and with large repositories, an in-place repair may be
desirable. This patch adds functionality for in-place repair of the
fncache.
The `hg debugrebuildfncache` command is introduced. It ensures the
fncache is up to date by reconstructing the fncache from all seen files
encountered during a brute force traversal of the repository's entire
history.
The command will add missing entries and will prune excess ones.
Currently, the command no-ops unless the repository has the fncache
requirement. The command could later grow the ability to "upgrade" an
existing repository to be fncache enabled, if desired.
When testing this patch on a local clone of the Firefox repository, it
removed a bunch of entries. Investigation revealed that removed entries
belonged to empty (0 byte size) .i filelogs. The functionality for
pruning fncache of stripped revlogs was introduced in f49d60fa40a5, so
the presence of these entries likely predates this feature.

revset: rework 'filteredset.last'

revset: improves time complexity of 'roots(xxx)'
The canonical way of doing 'roots(X)' is 'X - children(X)'. This is what the
implementation used to be. However, computing children is expensive because it
is unbounded. Any changesets in the repository may be a children of '0' so you
have to look at all changesets in the repository to compute children(0).
Moreover the current revsets implementation for children is not lazy, leading to
bad performance when fetching the first result.
There is a more restricted algorithm to compute roots:
roots(X) = [r for r in X if not parents(r) & X]
This achieve the same result while only looking for parent/children relation in
the X set itself, making the algorithm 'O(len(X))' membership operation.
Another advantages is that it turns the check into a simple filter, preserving
all laziness property of the underlying revsets.
The speed is very significant and some laziness is restored.
