revset: made ascgeneratorset a private class This class is not supposed to be used outside revset.py since it only wraps content that is used by baseset typed classes. It only gets created by revset operations or private methods.

cmdutil: changed walkchangerevs to use spanset instead of baseset Using a spanset takes almost no memory at all. A baseset builds the entire list in memory and is much slower for methods like __contains__.

revset: added sort methods to generatorsets Method needed to propagate sort calls amongst lazy structures. The generated list (stored in the object) is sorted. If the generated list did not contain all elements from the generator, we take care of that before sorting the list.

fix_bytesmod: use the "from mercurial" form of the import to avoid breaking httpclient Without this patch, 2to3's rewrites to httpclient cause it to fail to import. With this patch, it's probably hopelessly broken, but at least won't block forward progress on non-http2 functionality on Python 3.

commit: create new amend changeset as secret correctly for "--secret" option Before this patch, "hg commit --amend --secret" doesn't create new amend changeset as secret, even though the internal function "commitfunc()" passed to "cmdutil.amend()" make "phases.new-commit" configuration as "secret" temporarily. "cmdutil.amend()" uses specified "commitfunc" only for temporary amend commit, and creates the final amend commit changeset by "localrepository.commitctx()" directly with memctx. This patch creates new amend changeset as secret correctly for "--secret" option, by changing "phases.new-commit" configuration temporarily before "localrepository.commitctx()".

hg log: solves bug regarding hg log -r 0:null (issue4039) 'hg log -r 0:null' was showing only one changeset(the '-1' one) instead of the first two changesets.

killdaemons: drop superfluous L suffix from constant As far as I'm aware PEP 237[0] means this suffix is superfluous even on Python 2.4, and we can just drop it, which makes this code happy on Python 3. 0: http://legacy.python.org/dev/peps/pep-0237/

setup.py: fix 2.4 breakage in 77ab0abb

setup: handle more invalid python3 syntax This should keep the file portable to both python2 and python3.

revset: changed __add__ methods on lazy sets to return addsets (issue4191) Performance Benchmarking: $ hg --time log --graph --style compact --limit 6 -r 'sort((::. or bookmark() or heads(public())), "-rev")' time: real 1.540 secs (user 1.510+0.000 sys 0.020+0.000) $ ./hg --time log --graph --style compact --limit 6 -r 'sort((::. or bookmark() or heads(public())), "-rev")' time: real 1.240 secs (user 1.190+0.000 sys 0.040+0.010)

revset: added addset class with its basic methods This class addresses the problem of losing performance on the __contains__ method when adding two smart structures with fast membership testing.

revset: changed _children method to use lazy structures

revset: changed descendants revset to use lazy generators Performance Benchmarking: $ time hg log -qr "0:: and 0:5" ... real 0m3.665s user 0m3.364s sys 0m0.289s $ time ./hg log -qr "0:: and 0:5" ... real 0m0.492s user 0m0.394s sys 0m0.097s

revset: optimized _revancestors method based on order of revisions If the revisions for which the ancestors are required are in descending order, it lazily loads them into a heap to be able to yield values faster.

revset: changed ancestors revset to return lazy generators This will not improve revsets like "::tip" but will do when that gets intersected or substracted with another revset. Performance Benchmarking: $ time hg log -qr "draft() and ::tip" ... real 0m3.961s user 0m3.640s sys 0m0.313s $ time ./hg log -qr "draft() and ::tip" ... real 0m1.080s user 0m0.987s sys 0m0.083s

doc: show short description of each commands in generated documents Before this patch, short description of each commands is not shown in generated documents (HTML file and UNIX man page). This omitting may prevent users from understanding about commands. This patch show it as the 1st paragraph in the help section of each commands. This style is chosen because: - showing it as the section title in "command - short desc" style disallows referencing by "#command" in HTML file: in "en" locale, hyphen concatenated title is used as the section ID in HTML file for this style - showing it as the 1st paragraph in "command - short desc" style seems to be redundant: "command" appears also just before as the section title - showing it just after synopsis like "hg help command" seems not to be reasonable in UNIX man page This patch just writes short description ("d['desc'][0]") before "::", because it should be already "strip()"-ed in "get_desc()", or empty string for the command without description.

templater: make strings in template expressions be "string-escape"-ed correctly Changeset 64b4f0cd7336 (released with 2.8.1) fixed "recursively evaluate string literals as templates" problem (issue4102) by moving the location of "string-escape"-ing from "tokenizer()" to "compiletemplate()". But some parts in template expressions below are not processed by "compiletemplate()", and it may cause unexpected result. - 'expr' of 'if(expr, then, else)' - 'expr's of 'ifeq(expr, expr, then, else)' - 'sep' of 'join(list, sep)' - 'text' and 'style' of 'rstdoc(text, style)' - 'text' and 'chars' of 'strip(text, chars)' - 'pat' and 'repl' of 'sub(pat, repl, expr)' For example, '\n' of "{join(extras, '\n')}" is not "string-escape"-ed and treated as a literal '\n'. This breaks "Display the contents of the 'extra' field, one per line" example in "hg help templates". Just "string-escape"-ing on each parts above may not work correctly, because inside expression of nested ones already applies "string-escape" on string literals. For example: - "{join(files, '\n')}" doesn't return "string-escape"-ed string, but - "{join(files, if(branch, '\n', '\n'))}" does To fix this problem, this patch does: - introduce "rawstring" token and "runrawstring" method to handle strings not to be "string-escape"-ed correctly, and - make "runstring" method return "string-escape"-ed string, and delay "string-escape"-ing until evaluation This patch invokes "compiletemplate()" with "strtoken=exp[0]" in "gettemplate()", because "exp[1]" is not yet evaluated. This code path is tested via mapping ("expr % '{template}'"). In the other hand, this patch invokes it with "strtoken='rawstring'" in "_evalifliteral()", because "t" is the result of "arg" evaluation and it should be "string-escape"-ed if "arg" is "string" expression. This patch doesn't test "string-escape"-ing on 'expr' of 'if(expr, then, else)', because it doesn't affect the result.

templater: apply "stringify()" on sub expression to get string correctly Templating syntax allows nested expression to be specified as parts below, but they are evaluated as a generator and don't work correctly. - 'sep' of 'join(list, sep)' - 'text' and 'chars' of 'strip(text, chars)' In the former case, 'sep' returns expected string only for the first separation, and empty one for the second or later, because the generator has only one element. In the latter case, templating is aborted by exception, because the generator doesn't have 'strip()' method (as 'text') and can't be passed as the argument to 'str.strip()' (as 'chars'). This patch applies "stringify()" on these sub expression to get string correctly.

templater: avoid recursive evaluation of string literals completely Changeset 3d8bfe2ecf6d (released with 2.8.1) fixed "recursively evaluate string literals as templates" problem (issue4103) by introducing "_evalifliteral()". But some parts in template expressions below are still processed by the combination of "compiletemplate()" and "runtemplate()", and may cause same problem unexpectedly. - 'init' and 'hang' of 'fill(text, width, init, hang)' - 'expr' of 'sub(pat, repl, expr)' - 'label' of 'label(label, expr)' This patch processes them by "_evalifliteral()" instead of the combination of "compiletemplate()" and "runtemplate()" to avoid recursive evaluation of string literals completely.
