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.

tests: trivial fixes for Windows

py3: use encoding.strtolocal() to convert string to bytes Differential Revision: https://phab.mercurial-scm.org/D1557

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.

unamend: drop unused vars, query after taking lock, use ctx.hex() for extras This is the followup of review on D821. Differential Revision: https://phab.mercurial-scm.org/D1579

test-lfs: drop a hack for ignoring convert devel-warnings This was fixed on stable in 281214150561.

convert: restore the ability to use bzr < 2.6.0 (issue5733) This effectively conditionalizes a234b32b744a. Some Linux distributions (like CentOS 7) use really old versions, and the change referenced was causing exceptions to be thrown. Even though the deprecation warning says 'since 2.5.0', it wasn't marked as such in 2.5.1, but is by 2.6.0. This was tested with 2.4.2 and 2.6.0 with PYTHONWARNINGS=::DeprecationWarning, and both paths were exercized.

run-tests: mechanism to report exceptions during test execution Sometimes when running tests you introduce a ton of exceptions. The most extreme example of this is running Mercurial with Python 3, which currently spews thousands of exceptions when running the test harness. This commit adds an opt-in feature to run-tests.py to aggregate exceptions encountered by `hg` when running tests. When --exceptions is used, the test harness enables the "logexceptions" extension in the test environment. This extension wraps the Mercurial function to handle exceptions and writes information about the exception to a random filename in a directory defined by the test harness via an environment variable. At the end of the test harness, these files are parsed, aggregated, and a list of all unique Mercurial frames triggering exceptions is printed in order of frequency. This feature is intended to aid Python 3 development. I've only really tested it on Python 3. There is no shortage of improvements that could be made. e.g. we could write a separate file containing the exception report - maybe even an HTML report. We also don't capture which tests demonstrate the exceptions, so there's no turnkey way to test whether a code change made an exception disappear. Perfect is the enemy of good. I think the current patch is useful enough to land. Whoever uses it can send patches to imprve its usefulness. Differential Revision: https://phab.mercurial-scm.org/D1477

run-tests: organize options into argument groups And sort arguments so help output is more legible. There are probably a ton of ways to group things. I tried to picture the test harness as a pipeline and attempted to draw boundaries around stages in that pipeline to create the groupings. Differential Revision: https://phab.mercurial-scm.org/D1475
