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.

Added tag 3.5.2 for changeset 9a466b9f9792

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.

i18n-pt_BR: synchronized with f31ddc9bfa5f

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.
