exchange: teach pull about requested stream clones An upcoming patch will move the invocation of stream cloning logic to the normal pull code path (from localrepository.clone). In preparation for this, we teach pull() and pulloperation about whether a streaming clone is requested. The return logic in localrepository.clone() has been reformatted slightly because of line length issues.

streamclone: add explicit check for empty local repo Stream clone doesn't work with non-empty local repositories. In upcoming patches, we'll move stream cloning to the regular pull code path. Add an explicit check on the repository being empty to prevent streaming clones to non-empty repos.

streamclone: refactor code for deciding to stream clone Having this in a standalone function will eventually enable bundle2 to share code with the bundle1 code path. While I was here, I also added some comments to add clarity.

streamclone: move streaming clone logic from localrepo This is the last remnants of streaming clone code in localrepo.py. This is a mostly mechanical transplant of code to a new file. Only a rewrite of "self" to "repo" was performed. The code will be significantly refactored in upcoming patches. So don't scrutinize it too closely.

streamclone: move _allowstream() from wireproto While we're moving things into streamclone.py...

streamclone: move code out of exchange.py We bulk move functions from exchange.py related to streaming clones. Function names were renamed slightly to drop a component redundant with the module name. Docstrings and comments referencing old names and locations were updated accordingly.

streamclone: move stream_in() from localrepo Another basic content move. The underscore from the function name was removed to comply with naming standards.

streamclone: move applystreamclone() from localrepo.py Upcoming patches will modernize the streaming clone code. Streaming clone data and code kind of lives in its own world. exchange.py is arguably the most appropriate existing location for it. However, over a dozen patches from now it became apparent that there was a lot of code related to streaming clones and that having it contained within its own module would make it easier to comprehend. So, we establish streamclone.py. It's worth noting that streamclone.py existed a long time ago, last seen in the 1.6 release. It was removed in 04f76a954842. The function was renamed as part of the move because its old name was redundant with the new module name. The only other content change was "self" was renamed to "repo" and minor grammar in the docstring was updated.

exchange: add docstring to pull() This seems like the kind of important function that should be documented better.

localrepo: allow creating inherited locks This is part of a series that will allow locks to be inherited by subprocesses in limited circumstances.

error: make lock inheritance contract violations a subclass of RuntimeError This is more appropriate, per Pierre-Yves David.

templatekw: hide help of "branches" by DEPRECATED marker See 43e872a35f8a for details.

templatekw: remove dockeywords hack Now all template keywords are defined as real functions.

templatekw: port implementation of showparents() from changeset_templater It isn't cool, but we can peek at ui flag via repo.ui. So, it is possible to implement showparents() in templatekw, and therefore we can eliminate the dockeywords hack.

templatekw: reorder stub of showparents() function It will have an implementation.

changeset_printer: move _meaningful_parentrevs() to scmutil It will be used by templatekw.

test-run-tests: add globs for Windows There are two other unrelated failures in this test. For some reason child1 has a space after it, thus 2 spaces before the glob, otherwise the glob is ignored and removed.

test-commandserver: generate files with a fixed EOL for test stability The hashes were different on Windows.

test-debugextensions: sanitize JSON output for Windows Windows is printing a double backslash, which isn't handled by (glob): --- c:/Users/Matt/Projects/hg/tests/test-debugextensions.t +++ c:/Users/Matt/Projects/hg/tests/test-debugextensions.t.err @@ -47,7 +47,7 @@ { "buglink": "", "name": "color", - "source": "*/hgext/color.pyc", (glob) + "source": "c:\\Users\\Matt\\Projects\\hg\\hgext\\color.pyc", "testedwith": "internal" }, {

cmdutil: handle multiline translations of HG: messages safely Before this, if a localizer/localization included a multiline message, and didn't prefix the intermediate lines with 'HG: ', then the line would be a candidate for inclusion in the commit message -- which isn't ideal.

strip: compress bundle2 backup using BZ Storing uncompressed bundle on disk would be a regression. Strip backup using bundle2 are now compressed when requested.

writebundle: add a compression argument for the bundle2 case Bundle2 compression is more complex than the bundle1 one. Therefore it is handled by the bundler itself. Moreover, on-disk bundle2 will probably have a large number of flavors so simply adding a new "format" for it does not seems the way to go. This will be used in the next changeset to compress bundle2 strip backup.

strip: use bundle2 + cg2 by default when repository use general delta The bundle10 format (plain changegroup-01) does not support general delta and result into expensive delta re-computation when stripping. If the repository is general delta, we store backups as bundle20 containing a changegroup-02 payload. We remove the experimental feature related to strip backup bundle format because this achieve the same goal in a leaner way. Removing the experimental option is fine, that is why it experimental in the first place. Compression of these bundles are coming in later changesets.

largefiles: restore archiving largefiles with hgweb (issue4859) This regressed in 7699d3212994, when trying to conditionally disable archiving of largefiles. I'm not sure if wrapfunction() is the right way to do this, but it seems to work. The mysterious issue with lfstatus getting out of sync in the proxy and the unfiltered view crops up again here. See the referenced cset for more info.

help: hide deprecated filesets, revsets and template items if not verbose This allows us to hide {branches} template keyword in a better way. Currently it is achieved by copying keywords table and deleting 'branches' from it.

help: pass around ui to rewriter hooks (API) makeitemsdoc() will hide DEPRECATED items conditionally.

help: pass around ui to doc loader (API) This is necessary to hide DEPRECATED items conditionally. Flagged as API change because it will break "hg help git|subversion".

gendoc: use real ui in place of stdout ui attributes will be required by a help function, so a file object can't be used as a fake ui.

check-seclevel: use ui to show status and error messages Future patches will require ui module to be passed to a help function, so let's use it where appropriate. Additional parens are necessary to silence a check-code warning.

unbundle: test and fix for clean abort on unknown bundle2 feature This introduce a test for the feature and fix the exception name that is different on default.

localrepo: recreate phasecache if changelog was modified (issue4855) Because _phaserevs and _phasesets cache revision numbers, they must be invalidated if there are new commits or stripped revisions. We could do that by calling _phasecache.invalidate(), but it wasn't simple to be integrated with the filecache mechanism. So for now, phasecache will be recreated after repo.invalidate() if 00changelog.i was modified before.

progress: force a repaint of a printed progress bar after a clear() This avoids some visual flickering of the progress bar in convert and probably some other operations. Previously, a line of output would erase the progress bar, and then it would wait `progress.refresh` seconds (default of 0.1) before redrawing the progress bar. Now if we've ever painted a progress bar, we schedule the progress bar for immediate repainting on the next progress call, which helps lend the illusion that the progress bar is "always" there. In practice, it's merely there more of the time, but it ends up being a lot easier to read during convert.

tests: fix test-bundle2-format output Forgot to amend.

bundle2: allow compressed bundle This changeset adds support for a 'compression' parameter in bundle2 streams. When set, it controls the compression algorithm used for the payload part of the bundle2. There is currently no usage of this except in tests.

test-bundle2: dump bundle content using f --hexdump Thanks to Greg Szorc for pointing this out.

treemanifest: rework lazy-copying code (issue4840) The old lazy-copy code formed a chain of copied manifests with each copy. Under typical operation, the stack never got more than a couple of manifests deep and was fine. Under conditions like hgsubversion or convert, the stack could get hundreds of manifests deep, and eventually overflow the recursion limit for Python. I was able to consistently reproduce this by converting an hgsubversion clone of svn's history to treemanifests. This may result in fewer manifests staying in memory during operations like convert when treemanifests are in use, and should make those operations faster since there will be significantly fewer noop function calls going on. A previous attempt (never mailed) of mine to fix this problem tried to simply have all treemanifests only have a loadfunc - that caused somewhat weird problems because the gettext() callable passed into read() wasn't idempotent, so the easy solution is to have a loadfunc and a copyfunc.

manifest: rename treemanifest load functions to ease debugging I'm hunting an infinite recursion bug at the moment, and having both of these methods named just _load is muddying the waters slightly.

manifest: add id(self) to treemanifest __repr__ Also rename __str__ to __repr__ since that's what we really want for pdb.

bundlerepo: let bundle repo look in the _mancache When looking up a base revision, we were ignoring the contents that were already available in the manifest's _mancache. This patch allows us to use that data instead of reading from the revlog. This is useful in our pushrebase extension (which allows rebasing on the server side during a push) because it allows us to prefetch the bundle base manifest before aquiring the repo lock (1 second saving), which means doing less work inside the lock, which means a 20% higher commit rate.

check-seclevel: wrap entry point by function This is intended to narrow scope of local variables. The global _verbose flag will be replaced later by ui.verbose.

check-seclevel: set executable bit as it has shebang

bundle20: extract core payload generation in its own function We are about to allow compressing the core of the bundle2. So we extract the generation of this bits in its own parts to make this compression phases easier in a later changesets.

unbundle20: allow registering handlers for stream level parameters As a comment in the code have been asking for, it is now possible to register piece of code that handle parameters for the stream. I've been wondering is such function should be class methods or not. I eventually went for externally decorated methods to stick with the culture of extensibility from an extensions that apply to bundle2.

bundle2: allow to specify unsupported value on error A client may support an argument but not some of its values (eg: coming "compression" parameters). We allow this case to be carried in the exception.

bundle2: rename error exception class for unsupported feature The original name explicitly mention "Part", however it is also used outside of parts related feature. We rename from 'UnsupportedPartError' to 'BundleUnknownFeatureError' to fix this.

changegroup: use a different compression key for BZ in HG10 For "space saving", bundle1 "strip" the first two bytes of the BZ stream since they always are 'BZ'. So the current code boostrap the uncompressor with 'BZ'. This hack is impractical in more generic case so we move it in a dedicated "decompression".

monoblue: provide links to branches, tags and bookmarks by name This is adapted from cd842821db2c, that was added to paper for 3.5 release. It adds another way to refer to branches, tags and bookmarks in urls: by name. It's still possible to navigate to a specific changeset hash, but now you can get more descriptive urls straight from /summary page, for example. branchentry template (and so the whole branches table on /summary and /branches) lost the column that had a plain changeset hash, because tags and bookmarks don't have this column and also because there is already a way to address branch by its changeset hash (changeset link just next to it). Maybe we can instead bring this column with a plain changeset hash to tags and bookmarks, but this, more terse, new look feels fine.
