dispatch: replace _earlygetopt(strip=True) with new parser The execution order in cmdalias.__init__() is adjusted to set stripped args to self.givenargs, which is no longer updated in place.

dispatch: replace _earlyreq*() with new fancyopts-based parser

dispatch: alias --repo to --repository while parsing early options This prepares for replacing old _early*opt() functions. My initial attempt was to extend options table to support 'repository|repo' syntax. It worked, but seemed too invasive. So I decided to add an optional argument to fancyopts() instead. This also changes the nevernegate dict to be keyed by a canonical_name, not by an option-name for clarity.

paper: render changesets server-side on /graph page

hgweb: only include graph-related data in jsdata variable on /graph pages (BC) Historically, client-side graph code was not only rendering the graph itself, but it was also adding all of the changeset information to the page as well. It meant that JavaScript code needed to construct valid HTML as a string (although proper escaping was done server-side). It wasn't too clunky, even though it meant that a lot of server-side things were duplicated client-side for no good reason, but the worst thing about it was the data format it used. It was somewhat future-proof, but not human-friendly, because it was just a tuple: it was possible to append things to it (as was done in e.g. 270f57d35525), but you'd then have to remember the indices and reading the resulting JS code wasn't easy, because cur[8] is not descriptive at all. So what would need to happen for graph to have more features, such as more changeset information or a different vertex style (branch-closing, obsolete)? First you'd need to take some property, process it (e.g. escape and pass through templatefilters function, and mind the encoding too), append it to jsdata and remember its index, then go add nearly identical JavaScript code to 4 different hgweb themes that use jsdata to render HTML, and finally try and forget how brittle it all felt. Oh yeah, and the indices go to double digits if we add 2 more items, say phase and obsolescence, and there are more to come. Rendering vertex in a different style would need another property (say, character "o", "_", or "x"), except if you want to be backwards-compatible, it would need to go after tags and bookmarks, and that just doesn't feel right. So here I'm trying to fix both the duplication of code and the data format: - changesets will be rendered by hgweb templates the same way as changelog and other such pages, so jsdata won't need any information that's not needed for rendering the graph itself - jsdata will be a dict, or an Object in JS, which is a lot nicer to humans and is a lot more future-proof in the long run, because it doesn't use numeric indices What about hgweb themes? Obviously, this will break all hgweb themes that render graph in JavaScript, including 3rd-party custom ones. But this will also reduce the size of client-side code and make it more uniform, so that it can be shared across hgweb themes, further reducing its size. The next few patches demonstrate that it's not hard to adapt a theme to these changes. And in a later series, I'm planning to move duplicate JS code from */graph.tmpl to mercurial.js and leave only 4 lines of code embedded in those <script> elements, and even that would be just to allow redefining graph.vertex function. So adapting a custom 3rd-party theme to these changes would mean: - creating or copying graphnode.tmpl and adding it to the map file (if a theme doesn't already use __base__) - modifying one line in graph.tmpl and simply removing the bigger part of JavaScript code from there Making these changes in this patch and not updating every hgweb theme that uses jsdata at the same time is a bit of a cheat to make this series more manageable: /graph pages that use jsdata are broken by this patch, but since there are no tests that would detect this, bisect works fine; and themes are updated separately, in the next 4 patches of this series to ease reviewing.

hgweb: adopt child nodes in ajaxScrollInit on /graph pages too ajaxScrollInit is a function that loads more elements (e.g. changelog entries) when browser window is scrolled down to the bottom of the page. It basically fetches the next page from the server as HTML, finds container element in that document and "adopts" (essentially, moves) all its child nodes to the container in the current document. Currently, hgweb doesn't render any changesets on /graph page (everything is done in JavaScript), so there are no children to adopt. But there will be soon, so let's create a reusable function that does it. Hardcoding #graphnodes selector is suboptimal, but graph code already does this in two other places.

lfs: enable the extension locally after converting to an 'lfs' repo This is consistent with clone and share in the previous commits.

lfs: enable the extension locally after sharing a repo with 'lfs' requirement This is consistent with clone in the previous commit.

lfs: enable the extension locally after cloning a repo with 'lfs' requirement We do the same thing on clone for the largefiles extension, as a convenience. Similar to largefiles, it's probably safer to only enable this extension on a per repo basis because it is trivial to add an lfs file. And that gives the repository some centralized VCS characteristics.

log: translate column labels at once (issue5750) This makes sure that all columns are aligned. getlogcolumns() is hosted by templatekw so the namespaces module can see it. i18n/de.po is updated so test-log.t passes with no error. "obsolete:" and "instability:" are kept untranslated.

log: remove temporary variable 'date' used only once

merge with stable

lock: allow to configure when the lock messages are displayed We add a new 'ui.timeout.warn' config to set a grace period before we display lock related warning: waiting for lock on PATH held by PROCESS The config is based on 'ui.timeout' and expresses a number of seconds before the warning is displayed. Negative values disable the warning altogether. The messages go to the debug output to help people trouble-shooting deadlocks.

lock: add a trylock method handling the timeout and messaging logic We are about to make the messages around lock more flexible. We move all the currently logic into a function in the lock module. We'll update the message scheme in the next changeset.

lock: use configint for 'ui.timeout' config The ui object can do the conversion itself.

scmutil: improve format pattern used in nodesummaries As spotted by Yuya Nishihara, that value is an integer.

archive: pass thru mtime for directory archives, like other archive types do Without this files in the output archive directory have their mtimes set to whatever time they were written their. This is in this inconsistent with the other archivers, eg. zip, which use exactly the same time for all files. Works on my machine (Windows), but I don't have a *nix box available to run anything more thorough, unfortunately.

hgweb: remove negative top from .info line in graph "top: -Xpx" shifts a block up by X pixels, which can be used to visually compress two lines of text to have less space between them, in this case it's used for the changesets on /graph page. But not only it's not needed there (both lines fit fine into their allowed vertical space), but it would also look better (not as crammed, more vertically centered) without these negative values. "position: relative" is needed solely for the "top" property to have effect on the element, no children of the .info element rely on it, so let's remove it as well.
