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).

revlog: optionally cache the full text when adding revisions revlog instances can cache the full text of a single revision. Typically the most recently read revision is cached. When adding a delta group via addgroup() and _addrevision(), the full text isn't always computed: sometimes only the passed in delta is sufficient for adding a new revision to the revlog. When writing the changelog from a delta group, the just-added full text revision is always read immediately after it is written because the changegroup code needs to extract the set of files from the entry. In other words, revision() is *always* being called and caching the full text of the just-added revision is guaranteed to result in a cache hit, making the cache worthwhile. This patch adds support to _addrevision() for always building and caching the full text. This option is currently only active when processing changelog entries from a changegroup. While the total number of revision() calls is the same, the location matters: buildtext() calls into revision() on the base revision when building the full text of the just-added revision. Since the previous revision's _addrevision() built the full text and the the previous revision is likely the base revision, this means that the base revision's full text is likely cached and can be used to compute the current full text from just a delta. No extra I/O required. The end result is the changelog isn't opened and read after adding every revision from a changegroup. On my 2013 MacBook Pro running OS X 10.10.5 from an SSD and Python 2.7, this patch impacted the time taken to apply ~262,000 changesets from a mozilla-central gzip bundle: before: ~43s after: ~32s ~25% reduction in changelog processing times. Not bad.

revlog: drop local assignment of cache variable The purpose of this code was to provide thread safety. With the conversion of hgweb to use separate localrepository instances per request/thread, we should no longer have any consumers that need to access revlog instances from multiple threads. Remove the code.

revlog: rename generic "i" variable to "indexdata" Increase readability.

hg: always create new localrepository instance cachedlocalrepo.copy() didn't actually create new localrepository instances. This meant that the new thread isolation code in hgweb wasn't actually using separate localrepository instances, even though it was properly using separate cachedlocalrepo instances. Because the behavior of the API changed, the single caller in hgweb had to be refactored to always call _webifyrepo() or it may not have used the proper filter. I confirmed via print() debugging that id(repo) is in fact different on each thread. This was not the case before. For reasons I can't yet explain, this does not fix issue4756. I suspect there is shared cache somewhere that isn't thread safe.

test-bad-extension: reduce dependencies on other things test-bad-extension would jitter if the format of the first line of hg help changed, which isn't relevant to its goal.

help: fix help argument parsing and documentation support combining -c and -e previously -k was misdocumented: * the first line didn't mention it * the help half implied you could do help -k keyword topic with these changes, -k just changes the search method support -c and -e for -k searches

minirst: establish leveling for nested definitions
