Added signature for changeset 540cd0ddac49

Added tag 3.4.2 for changeset 540cd0ddac49

transplant: only pull the transplanted revision (issue4692) For some reason, transplant was pulling all remote revisions when transplanting from a remote repository (unless --branch was specified).

transplant: update test to use hash for remote transplant Transplant is apparently allowing using revision numbers when transplanting through http. I call this nonsense and update the test to use an explicit hash. This "feature" will break in the next change fixing another bug.

changegroup: properly compute common base in changeggroupsubset (issue4736) The computation of roots was buggy, any ancestor of a bundled merge which was also a descendant of the parents of a bundled revision were included as part of the bundle. We fix it and add a test for strip (which revealed the problem). Check the test for a practical usecase.

templater: parse \"...\" as string for 2.9.2-3.4 compatibility (issue4733) As of Mercurial 3.4, there were several syntax rules to process nested template strings. Unfortunately, they were inconsistent and conflicted each other. a. buildmap() rule - template string is _parsed_ as string, and parsed as template - <\"> is not allowed in nested template: {xs % "{f(\"{x}\")}"} -> parse error - template escaping <\{> is handled consistently: {xs % "\{x}"} -> escaped b. _evalifliteral() rule - template string is _interpreted_ as string, and parsed as template in crafted environment to avoid double processing of escape sequences - <\"> is allowed in nested template: {if(x, "{f(\"{x}\")}")} - <\{> and escape sequences in string literal in nested template are not handled well c. pad() rule - template string is first interpreted as string, and parsed as template, which means escape sequences are processed twice - <\"> is allowed in nested template: {pad("{xs % \"{x}\"}', 10)} Because of the issue of template escaping, issue4714, 7298da81f5a9 (in stable) unified the rule (b) to (a). Then, 576d6c74784b (in default) unified the rule (c) to (b) = (a). But they disabled the following syntax that was somewhat considered valid. {if(rev, "{if(rev, \"{rev}\")}")} {pad("{files % \"{file}\"}", 10)} So, this patch introduces \"...\" literal to work around the escaped-quoted nested template strings. Because this parsing rule exists only for the backward compatibility, it is designed to copy the behavior of old _evalifliteral() as possible. Future patches will introduce a better parsing rule similar to a command substitution of POSIX shells or a string interpolation of Ruby, where extra escapes won't be necessary at all. {pad("{files % "{file}"}", 10)} ~~~~~~~~~~~~~~~~~~ parsed as a template, not as a string Because <\> character wasn't allowed in a template fragment, this patch won't introduce more breakages. But the syntax of nested templates are interpreted differently by people, there might be unknown issues. So if we want, we could instead remove db7463aa080f, 890845af1ac2 and 7298da81f5a9 from the stable branch as the bug fixed by these patches existed for longer periods. 554d6fcc3c8, "strip single backslash before quotation mark in quoted template", should be superseded by this patch. I'll remove it later.

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.

share: replace reference to 'sopener' with 'svfs' sopener is deprecated. 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.

global: mass rewrite to use modern octal syntax Python 2.6 introduced a new octal syntax: "0oXXX", replacing "0XXX". The old syntax is not recognized in Python 3 and will result in a parse error. Mass rewrite all instances of the old octal syntax to the new syntax. This patch was generated by `2to3 -f numliterals -w -n .` and the diff was selectively recorded to exclude changes to "<N>l" syntax conversion, which will be handled separately.

revert: change the direction of revert -i After the discussion on the list about hg revert -i, it seems like we are satisfied with what we called proposition 2. It shows the changes to revert in the same direction as hg diff. This patch makes it the default option. It changes all the + in - and vice versa in the tests for revert -i.

revert: change a test to make the change of direction of revert -i easier Currently we are handling editing of newly-added files with the interactive interface. We are not handling editing of deleted files. In the test for revert, we were editing a newly-added file. Since we want to change the direction of revert -i, this editing of a newly-added file will become editing of a deleted file. Since we don't support that, this patch changes the test to make the rest of the series cleaner.

parser: update documentation about tokenizer and elements

parser: accept iterator of tokens instead of tokenizer function and program This can simplify the interface of parse() function. Our tokenizer tends to have optional arguments other than the message to be parsed. Before this patch, the "lookup" argument existed only for the revset, and the templater had to pack [program, start, end] to be passed to its tokenizer.
