demandimport: support importing builtins for Python 3 __builtin__ was renamed to builtins in Python 3. If importing __builtin__ fails, fall back to importing builtins in order to support Python 3.

demandimport: alias __builtin__ as builtins Python 3 renamed the __builtin__ module to builtins. In preparation for supporting Python 3, alias the imported module as "builtins."

bufferedinputpipe: remove N^2 computation of buffer length (issue4735) The assumption that dynamically computing the length of the buffer was N^2, but negligible because fast was False. So we drop the dynamic computation and manually keep track of the buffer length.

bufferedinputpipe: remove an outdate comment This comment is the remains of a intermediate implementation using self._buffer += data This implementation never made it to the repository and we can safely drop the comment.

statichttprepo: kill off sopener

obsolete: replace references to 'sopener' with 'svfs'

exchange: replace references to 'sopener' with 'svfs'

localrepo: kill off sopener (API) sopener is deprecated since 7034365089bf (Mercurial 2.3). It's annoying for extension authors to have to deal with both. Let's just kill it off.

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).

check-code: detect legacy exception syntax We just rewrote all files to use modern exception syntax. Ban the old form. This will detect the "except type, instance" and "except (type1, type2), instance" forms.

global: mass rewrite to use modern exception syntax Python 2.6 introduced the "except type as instance" syntax, replacing the "except type, instance" syntax that came before. Python 3 dropped support for the latter syntax. Since we no longer support Python 2.4 or 2.5, we have no need to continue supporting the "except type, instance". This patch mass rewrites the exception syntax to be Python 2.6+ and Python 3 compatible. This patch was produced by running `2to3 -f except -w -n .`.

check-code: detect legacy octal syntax Now that we have mass rewriting all files to use the modern octal syntax, detect and ban the legacy syntax, which is no longer supported in Python 3.
