monoblue: split a long line in filelogentry template The whole td has a nowrap class, which disallows breaking the line, so it's not required to use non-breakable spaces.

readbundle: fix typo of None compression The test simulates pre-d1b16a746db6 hgweb that sends "unbundle" capability with no argument.

readbundle: map 'HG10UN' to None compression In line with the other previous changes

getsubset: use None to request uncompressed changegroup

bundle: use None when unpacking uncompressed changegroup Let's be more modern!

writebundle: use 'None' instead of 'UN' for the bundle2 case Let's be modern!

compression: use 'None' for no-compression This seems more idiomatic and clearer. We still support both None and 'UN' for now because no user are migrated.

changegroup: move all compressions utilities in util We'll reuse the compression for other things (next target bundle2), so let's make it more accessible and organised.

obsolete: clarify that 'successorssets' returns the latest successors We do not return the first successors we found, we returns the latest (non obsolete (mostly)) one following the obsolete link transitively. We update the documentation to make this clean.

obsolete: drop an empty line at the end of a docstring This empty line is useless, let's drop it.

traceback: allow providing a local support contact point The extensions blaming code is fine for casual users but pretty terrible for corporate environments that can deploy a large amount of extensions to unsuspecting users. Reports will likely blame a random "innocent" extension (in our case crecord) and the hint in the message will triggers endless debug attempts from the user. We introduce a "ui.supportcontact" option that allow such big company to redirect their users to their own support desk. This disables all extensions blaming and just point people to the local support in all cases.

dispatch: pre-indent the extensions blaming logic We are about to put some real conditional here, but pre-indenting in it's own changesets makes next patch much cleaner.

tests: check for inconsistently translated DEPRECATED Mercurial expects DEPRECATED to be translated consistently, not doing that breaks Mercurial.

i18n-fr: reject translation which is missing DEPRECATED

i18n-pt_BR: select a single definition of DEPRECATED Mercurial expects DEPRECATED to be translated consistently, not doing that breaks Mercurial.

i18n-sv: select a single definition of DEPRECATED Mercurial expects DEPRECATED to be translated consistently, not doing that breaks Mercurial.

i18n-ro: use ()s instead of [] for DEPRECATED

i18n-ro: include translation of DEPRECATED

i18n-zh_CN: include translation of DEPRECATED

i18n-it: include translation of DEPRECATED

i18n-da: include translation of DEPRECATED

test-i18n: always run non gettext tests

localrepo: refresh filecache stats only if transaction finished successfully If commit is aborted by pretxncommit hook, in-memory changelog and manifest have entries that would be added. So they must be discarded on invalidate(). But the mechanism introduced by a710936c3037 doesn't handle this case well. It tries to mitigate the penalty of invalidate() by marking in-memory cache as "clean" on unlock assuming that they are identical to the stored data. But this assumption is wrong if stored data are rolled back by tr.abort(). This patch moves the hook to post-close action so that it will never be triggered on abort. This bug was originally reported to thg, which is only reproducible in command-server process on unix, evolve disabled. https://bitbucket.org/tortoisehg/thg/issues/4285/

localrepo: move closure of lock release to class It only captures "self", so it isn't necessary to be created dynamically.

highlight: add highlightfiles config option which takes a fileset (issue3005) Highlight extension lacked a way to limit files by size, by extension, and/or by any other part of file path. A good solution would be to use a fileset, since it can check file path, extension and size (and more) in one expression. So this change introduces such an option, highlighfiles, which takes a fileset and on each request decides if the requested file should be highlighted. The default "size('<5M')" is, in a way, suggested in issue3005. checkfctx() limits the amount of work to just one file (subset kwarg in fileset.matchctx()). Monkey-patching works around issue4568, otherwise using filesets here while running hgweb in directory mode would say, for example, "Abort: **.py not under root", but this fix is very local and probably far from ideal. I suspect there to be a way to fix this for the whole hgweb and resolve the issue, but I don't know how to do it.

posix: shellquote do not require quoting for "+" (issue4818)

hgweb: consume generator inside context manager (issue4756) If code inside a context manager returns a generator, the context manager exits before the generator is iterated. hgweb was using a context manager to control thread safe access to a localrepository instance. But it was returning a generator, so there was a race condition between a previous request streaming a response to the client and a new request obtaining the released but in use repository. By iterating the generator inside the context manager, we ensure we don't release the repo instance until after the response has finished. With this change, hgweb finally appears to have full localrepository isolation between threads. I can no longer reproduce the 2 exceptions reported in issue4756. test-hgweb-non-interactive.t has been modified to consume the output of calling into a WSGI application. Without this, execution of the WSGI application stalls because of the added yield statement.

histedit: use one editor when multiple folds happen in a row (issue3524) (BC) This was the first ever feature request for histedit, originally filed back on April 4, 2009. Finally fixed. In the future we'll probably want to make it possible for other preprocessing steps to be added to the list, but for now we're skipping that because it's unclear what the API should look like without a proposed consumer.

hgweb: replace .sourcelast with .bottomline that does the same In paper and Coal, basically, div.sourcelast was only used to make a 1px border on the bottom of file source view (and only there). It's better to use bottomline class, that also exists for the same purpose (visually), but is used more widely and works without needing an empty <div>.

coal: copy newer things from paper Basically, coal style in hgweb is intended to be functionally equivalent (just different in style) to paper, and does this by reusing almost all templates from paper (except header.tmpl, where it specifies a different css file). Looks like everybody forgot this and so many improvements to paper templates, that should've also made it into coal, were often only half-done there (usually thanks to template reuse). Let's fix this by bulk-copying missing things from paper/map and style-paper.css to coal/map and style-coal.css. There were many improvements to paper that didn't touch coal, and that makes it hard to untangle the code and split this patch into many, but here are some of the changes (paper-only), that now get into coal: 41c4bdd1d585 - hgweb: color line which is linked to in file source view f3393d458bf5 - hgweb: highlight line which is linked to at annotate view f2e4fdb3dd27 - hgweb: code selection without line numbers in file source view 5ec5097b4c0f - hgweb: add line wrapping switch to file source view bf661a03fddc - hgweb: use css margin instead of empty <p> before diffstat table It also fixes line anchor in annotateline template (#42 vs #l42).
