phase: rename getphaserevs to loadphaserevs This function is: - already loading the data in place, - used once in the code. So we drop the return value and change the name to make this obvious. We keep the function public because we'll have to use it in revset.

test-subrepo-recursion: more aggressively regex 'unzip -l' output for 10.10 The output on 10.10 looks like this: Length Date Time Name -------- ---- ---- ---- 172 01-01-80 00:00 .hg_archival.txt 10 01-01-80 00:00 .hgsub 45 01-01-80 00:00 .hgsubstate 3 01-01-80 00:00 x.txt 10 01-01-80 00:00 foo/.hgsub 45 01-01-80 00:00 foo/.hgsubstate 9 01-01-80 00:00 foo/y.txt 9 01-01-80 00:00 foo/bar/z.txt -------- ------- 303 8 files (2 digit year, shorter -- separators and closer columns). We don't care about any of that, so ignore it.

contrib: introduce an all-revsets.txt file This file should gather all revsets ever thought interesting by anyone. That way one can check the impact of a change when touching something revset-ish. See inline comments for details. This file have been refilled with all the entry I could automatically find from changeset descriptions. I assume we missed some not using 'revsetbenchmarks.py' output.

contrib: rename revsetbenchmarks.txt to 'base-revsets.txt' We rename the file and document its purpose. We'll be introducing another file gathering revsets useful for benchmark of the predicate themsleves in a coming changesets.

revsetbenchmarks: add main documention for the script This allow us to document the fact we can use comment in the file listing revsets.

hgweb: don't dereference symbolic revision in paper & coal style (issue2296) Let's make paper (and coal, since it borrows so much from paper) templates use symbolic revision in navigation links. The majority of links (log, filelog, annotate, etc) still use node hashes. Some pages don't have permanent links to current node hash (so it's not very easy to go from /rev/tip to /rev/<tip hash>), this will be addressed in future patches.

hgweb: don't dereference symbolic revision in gitweb style Let's make gitweb templates use symbolic revision in navigation links. The majority of links (log, filelog, annotate, etc) still use node hashes. Some pages don't have permanent links to current node hash (so it's not very easy to go from /rev/tip to /rev/<tip hash>), this will be addressed in future patches.

hgweb: don't dereference symbolic revision in monoblue style Let's make monoblue templates use symbolic revision in navigation links. The majority of links (log, filelog, annotate, etc) still use node hashes. Some pages don't have permanent links to current node hash (so it's not very easy to go from /rev/tip to /rev/<tip hash>), this will be addressed in future patches.

hgweb: don't dereference symbolic revision in spartan style Let's make spartan templates use symbolic revision in navigation links. The majority of links (log, filelog, annotate, etc) still use node hashes, and many pages also have permanent link to current node hash (i.e. you can go from /rev/tip to /rev/<tip hash> without manual url editing), so it's safe to update navigation.

hgweb: provide symrev (symbolic revision) property to the templates One of the features of hgweb is that current position in repo history is remembered between separate requests. That is, links from /rev/<node_hash> lead to /file/<node_hash> or /log/<node_hash>, so it's easy to dig deep into the history. However, such links could only use node hashes and local revision numbers, so while staying at one exact revision is easy, staying on top of the changes is not, because hashes presumably can't change (local revision numbers can, but probably not in a way you'd find useful for navigating). So while you could use 'tip' or 'default' in a url, links on that page would be permanent. This is not always desired (think /rev/tip or /graph/stable or /log/@) and is sometimes just confusing (i.e. /log/<not the tip hash>, when recent history is not displayed). And if user changed url deliberately to say default instead of <some node hash>, the page ignores that fact and uses node hash in its links, which means that navigation is, in a way, broken. This new property, symrev, is used for storing current revision the way it was specified, so then templates can use it in links and thus "not dereference" the symbolic revision. It is an additional way to produce links, so not every link needs to drop {node|short} in favor of {symrev}, many will still use node hash (log and filelog entries, annotate lines, etc). Some pages (e.g. summary, tags) always use the tip changeset for their context, in such cases symrev is set to 'tip'. This is needed in case the pages want to provide archive links. highlight extension needs to be updated, since _filerevision now takes an additional positional argument (signature "web, req, tmpl" is used by most of webcommands.py functions). More references to symbolic revisions and related gripes: issue2296, issue2826, issue3594, issue3634.

archive: support 'wdir()' This is a step toward replacing the extdiff internals with archive, in order to support 'extdiff -S'. Only Mercurial subrepos are supported for now. If a file is missing from the filesystem, it is silently skipped. Perhaps it should warn, but it cannot abort when working with extdiff because deleting a file is a legitimate diff.

subrepo: allow a representation of the working directory subrepo Some code cannot handle a subrepo based on the working directory (e.g. sub.dirty()), so the caller must opt in. This will be useful for archive, and perhaps some other commands. The git and svn methods where this is used may need to be fixed up on a case by case basis.

templater: comment that gettemplate() has different name resolution order I've tried to unify gettemplate() with buildtemplate(), but it didn't go well because gettemplate() have to bypass mapping dict. For example, web templates have '{tags%changelogtag}' and 'changelogtag' is defined in both mapping, the default, and context.cache, sourced from map file. In general, mapping shadows context variables, but gettemplate() have to pick it from context.cache.

templater: drop strtoken argument from compiletemplate() There's no "rawstring" template now.

templater: do not reevaluate rawstring as template (BC) The previous patch made 'string' is always interpreted as a template. So this patch removes the special handling of r'rawstring' instead. Now r'' disables template processing at all.

templater: take any string literals as template, but not for rawstring (BC) This patch series is intended to unify the interpretation of string literals. It is breaking change that boldly assumes a. string literal "..." never contains template-like fragment or it is intended to be a template b. we tend to use raw string literal r"..." for regexp pattern in which "{" should have different meaning Currently, we don't have a comprehensible rule how string literals are evaluated in template functions. For example, fill() takes "initialindent" and "hangindent" as templates, but not for "text", whereas "text" is a template in pad() function. date(date, fmt) diff(includepattern, excludepattern) fill(text, width, initialident: T, hangindent: T) get(dict, key) if(expr, then: T, else: T) ifcontains(search, thing, then: T, else: T) ifeq(expr1, expr2, then: T, else: T) indent(text, indentchars, firstline) join(list, sep) label(label: T, expr: T) pad(text: T, width, fillchar, right) revset(query, formatargs...]) rstdoc(text, style) shortest(node, minlength) startswith(pattern, text) strip(text, chars) sub(pattern, replacement, expression: T) word(number, text, separator) expr % template: T T: interpret "string" or r"rawstring" as template This patch series adjusts the rule as follows: a. string literal, '' or "", starts template processing (BC) b. raw string literal, r'' or r"", disables both \-escape and template processing (BC, done by subsequent patches) c. fragment not surrounded by {} is non-templated string "ccc{'aaa'}{r'bbb'}" ------------------ *: template --- c: string --- a: template --- b: rawstring Because this can eliminate the compilation of template arguments from the evaluation phase, "hg log -Tdefault" gets faster. % cd mozilla-central % LANG=C HGRCPATH=/dev/null hg log -Tdefault -r0:10000 --time > /dev/null before: real 4.870 secs (user 4.860+0.000 sys 0.010+0.000) after: real 3.480 secs (user 3.440+0.000 sys 0.030+0.000) Also, this will allow us to parse nested templates at once for better error indication.

templater: move runtemplate function out of buildmap/runmap pair The next patch will introduce buildtemplate function that should be defined near runtemplate. But I don't want to insert it between buildmap and runmap.

phase: also overwrite phase's sets when replacing a phasecache We need to copy this new attributes around too. This fix an issue where phases data used by 'not public()' were not invalidated properly.

phase: invalidate the phase's set cache alongside the revs Invalidate was leaving set data around leading to possible bugs in revset.

phase: also copy phase's sets when copying phase cache We forgot to add such copy when we added the attributes.

verify: check the subrepository references in .hgsubstate While hopefully atypical, there are reasons that a subrepository revision can be lost that aren't covered by corruption of the .hgsubstate revlog. Such things can happen when a subrepo is amended, stripped or simply isn't pulled from upstream because the parent repo revision wasn't updated yet. There's no way to know if it is an error, but this will find potential problems sooner than when some random revision is updated. Until recently, convert made no attempt at rewriting the .hgsubstate file. The impetuous for this is to verify the conversion of some repositories, and this is orders of magnitude faster than a bash script from 0..tip that does an 'hg update -C $rev'. But it is equally useful to determine if everything has been pulled down before taking a thumb drive on the go. It feels somewhat wrong to leave this out of verifymod (mostly because the file is already read in there, and the final summary is printed before the subrepos are checked). But verifymod looks very low level, so importing subrepo stuff there seems more wrong.

context: override workingctx.hex() to avoid a crash Since node is None for workingctx, it can't use the base class implementation of 'hex(self.node())'. It doesn't appear that there are any current callers of this, but there will be when archive supports 'wdir()'. My first thought was to use "{p1node}+", but that would cause headaches elsewhere [1]. We should probably fix up localrepository.__getitem__ to accept this hash for consistency, as a followup. This works, if the full hash is specified: @@ -480,7 +480,7 @@ return dirstate.dirstate(self.vfs, self.ui, self.root, validate) def __getitem__(self, changeid): - if changeid is None: + if changeid is None or changeid == 'ff' * 20: return context.workingctx(self) if isinstance(changeid, slice): return [context.changectx(self, i) That differs from null, where it will accept any number of 0s, as long as it isn't ambiguous.
