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).

templatekw: correct typo in activebookmark documentation

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.

verify: print hint to run debugrebuildfncache Corrupt fncache is now a recoverable operation. Inform the user how to recover from this warning.

repair: add functionality to rebuild fncache Currently, there is no way to recover from a missing or corrupt fncache file in place (a clone is required). For certain use cases such as servers and with large repositories, an in-place repair may be desirable. This patch adds functionality for in-place repair of the fncache. The `hg debugrebuildfncache` command is introduced. It ensures the fncache is up to date by reconstructing the fncache from all seen files encountered during a brute force traversal of the repository's entire history. The command will add missing entries and will prune excess ones. Currently, the command no-ops unless the repository has the fncache requirement. The command could later grow the ability to "upgrade" an existing repository to be fncache enabled, if desired. When testing this patch on a local clone of the Firefox repository, it removed a bunch of entries. Investigation revealed that removed entries belonged to empty (0 byte size) .i filelogs. The functionality for pruning fncache of stripped revlogs was introduced in f49d60fa40a5, so the presence of these entries likely predates this feature.

import: cross-reference patch.fuzz option from `hg help import`

import: cross-reference ui.patch option from `hg help import` This is a fairly obscure patch option. It seems reasonable to expose it a bit more from the help text for `hg import`.

doc: document the ui.patch option This option has been undocumented since e56c7e05c7e6 (July 2007).

revset: rework 'filteredset.last' 'isascending' and 'isdescending' are methods, not attributes. This led 'last()' to misbehave on some non-ascending filtered sets.

revset: improves time complexity of 'roots(xxx)' The canonical way of doing 'roots(X)' is 'X - children(X)'. This is what the implementation used to be. However, computing children is expensive because it is unbounded. Any changesets in the repository may be a children of '0' so you have to look at all changesets in the repository to compute children(0). Moreover the current revsets implementation for children is not lazy, leading to bad performance when fetching the first result. There is a more restricted algorithm to compute roots: roots(X) = [r for r in X if not parents(r) & X] This achieve the same result while only looking for parent/children relation in the X set itself, making the algorithm 'O(len(X))' membership operation. Another advantages is that it turns the check into a simple filter, preserving all laziness property of the underlying revsets. The speed is very significant and some laziness is restored. -) revset without 'roots(...)' to compare to base line 0) before this change 1) after this change revset #0: roots((tip~100::) - (tip~100::tip)) plain min last -) 0.001082 0.000993 0.000790 0) 0.001366 0.001385 0.001339 1) 0.001257 92% 0.001028 74% 0.000821 61% revset #1: roots((0::) - (0::tip)) plain min last -) 0.134551 0.144682 0.068453 0) 0.161822 0.171786 0.157683 1) 0.137583 85% 0.146204 85% 0.070012 44% revset #2: roots(tip~100:) plain min first last -) 0.000219 0.000225 0.000231 0.000229 0) 0.000513 0.000529 0.000507 0.000539 1) 0.000463 90% 0.000269 50% 0.000267 52% 0.000463 85% revset #3: roots(:42) plain min first last -) 0.000119 0.000146 0.000146 0.000146 0) 0.000231 0.000254 0.000253 0.000260 1) 0.000216 93% 0.000186 73% 0.000184 72% 0.000244 93% revset #4: roots(not public()) plain min first -) 0.000478 0.000502 0.000504 0) 0.000611 0.000639 0.000634 1) 0.000604 0.000560 87% 0.000558 revset #5: roots((0:tip)::) plain min max first last -) 0.057795 0.004905 0.058260 0.004908 0.038812 0) 0.132845 0.118931 0.130306 0.114280 0.127742 1) 0.111659 84% 0.005023 4% 0.111658 85% 0.005022 4% 0.092490 72% revset #6: roots(0::tip) plain min max first last -) 0.032971 0.033947 0.033460 0.032350 0.033125 0) 0.083671 0.081953 0.084074 0.080364 0.086069 1) 0.074720 89% 0.035547 43% 0.077025 91% 0.033729 41% 0.083197 revset #7: 42:68 and roots(42:tip) plain min max first last -) 0.006827 0.000251 0.006830 0.000254 0.006771 0) 0.000337 0.000353 0.000366 0.000350 0.000366 1) 0.000318 94% 0.000297 84% 0.000353 0.000293 83% 0.000351 revset #8: roots(0:tip) plain min max first last -) 0.002119 0.000145 0.000147 0.000147 0.000147 0) 0.047441 0.040660 0.045662 0.040284 0.043435 1) 0.038057 80% 0.000187 0% 0.034919 76% 0.000186 0% 0.035097 80% revset #0: roots(:42 + tip~42:) plain min max first last sort -) 0.000321 0.000317 0.000319 0.000308 0.000369 0.000343 0) 0.000772 0.000751 0.000811 0.000750 0.000802 0.000783 1) 0.000632 81% 0.000369 49% 0.000617 76% 0.000358 47% 0.000601 74% 0.000642 81%

revsetbenchmark: do not abort on failure to run a revset Instead of aborting the whole process, we just skip entry for revset that failed to run.

osutil: remove Python 2.4 errno conversion workaround

patch: remove email import workaround for Python 2.4 Python 2.6 provides access to the sub-modules just fine. This workaround is no longer needed since we no longer support Python 2.4.
