run-tests: Pass arguments into argument parser Before, arguments were not passed into the optparse.OptionParser instance and were coming from sys.argv. This patch enables consumers to define the list of arguments to parse without having to adjust sys.argv.

bundle2: rename part to bundlepart We are going to introduce an `unbundlepart` dedicated to reading bundle. So we need to rename the one used to create bundle. Even if dedicated to creation, this is still used for unbundling until we get the new class.

bundle2: comment to clarify why the handler call is where it is The reason why it is here is not obvious. I'm the one who wrote it there in the first place and almost moved it 2 weeks later.

bundle2: use chunkbuffer for exchange.getbundle We can use `util.chunkbuffer` instead.

bundle2: lazily generate the changegroup part in exchange.getbundle Now that we have lazy generation of parts, let's use it.

bundle2: support chunk iterator as part data When the `part.data` attribute is an iterator, we assume it is an iterator of chunks and use it. We use a chunkbuffer to yield chunks of 4096 bytes. The tests are updated to use this feature.

bundle2: extract a _payloadchunks method for part We are preparing streaming capability for part. So the generation of payload chunk will becomes more complex. We extract this part in its own function before any changes.

changegroup: move chunk extraction into a getchunks method of unbundle10 This code used to be in `writebundle` only. We needs to make it more broadly available for bundle2. The "changegroup" bundle2 part has to retrieve the binary content of changegroup stream. We moved the chunks retrieving code into the `unbundle10` object directly and the `writebundle` code is now using that. This split is useful for bundle2 purpose, we want to be able to easily stream changegroup content in a part. To keep thing simples, we kept compression out of the new methods. If it make more sense in the future, compression may get included in this function too.

bundle2: use reply part to return result of addchangegroup We now have an official way to return the result of addchangegroup. The tests are updated to check that the return bundle is properly created. It will be used when push is bundle2 enabled.

bundle2: produce a bundle2 reply We do not know yet what kind of data future features and extensions will need to exchange. To handle that, bundle2 allows to send arbitrary content to the server. As a consequence, we need to be able to reply arbitrary content to the client. And, we can use bundle2 to transmit those arbitrary data. When a client will push a bundle2 to the server, the server will reply with a bundle2 itself. This changeset installs the first stone of this logic and test it.

bundle2: add reply awareness to unbundlerecords We need an efficient way to handle bundle replies. The unbundle records class is extended to carry such data.

bundle2: add an integer id to part For sending response to a pushed bundle, we need to link reply parts to request part. We introduce a part id for this purpose. This is a 32 bit unique integer stored in the header.

largefiles: don't prompt when one side of merge was changed but didn't change This can happen after backout or grafts or criss cross merges. We already do the same (but slightly different) thing in manifestmerge and filemerge.

color: fallback and test label as an effect With this changeset, we can now send a color name directly to the label function, e.g. $ hg log -r . -T "{label('red', node|short)}\n"

color: extract method for determining a valid effect This patch is just setup work so that we can reduce code duplication and have one place to define a valid effect.

revlog: use context ancestor instead of changelog ancestor We want to move in this direction.

copies: guard debug section with ui.debugflag

copies: remove _checkcopies wrapper - it does no good mergecopies might be doomed but it is not dead yet ...

transplant: use context ancestor instead of changelog ancestor We want to move in this direction. ctx.ancestor is in a better position for handling a situation with multiple ancestors.

commit: use revlog.commonancestors instead of .ancestor This do probably not make any real difference but is slightly more correct and we would like to get rid of flog.ancestor.

backout: don't limit heritage check to a single ancestor This do probably not make any real difference but is slightly more correct and we would like to get rid of changelog.ancestor.

ancestor: remove unused genericancestor

context: remove unused filectx.ancestor

shelve: add "writebundle()" to invoke "writebundle()" with relative path and vfs

shelve: add "applybundle()" to invoke "readbundle()" with relative path and vfs "applybundle()" also includes "addchangegroup()" invocation to encapsulate "vfs.join()" inside it.

bundlerepo: treat temporarily extracted bundle file via vfs

vfs: add "mkstemp()"

repair: make "strip()" treat bundle files via vfs This patch makes "repair.strip()" treat bundle files via vfs. This patch also avoids applying "vfs.join()" on the value returned by "changegroup.writebundle()", to get relative path from "_bundle()".

changegroup: add "vfs" argument to "readbundle()" to pass relative filename

repair: make paths in "_bundle()" relative to ".hg" This patch makes paths below in "_bundle()" relative to ".hg": - backup directory ("strip-backup"), and - bundle file under backup directory "vfs" is passed to "changegroup.writebundle()" to use relative path directly. This patch applies "vfs.join()" on the value returned by "_bundle()", because the caller expect it to return absolute path. This will be changed by succeeding patch changing the caller side.

changegroup: add "vfs" argument to "writebundle()" for relative access via vfs Before this patch, filename specified to "changegroup.writebundle()" should be absolute one. In some cases, they should be relative to repository root, store and so on (backup before strip, for example). This patch adds "vfs" argument to "writebundle()", and makes "writebundle()" open (and unlink) "filename" via vfs for relative access, if both filename and vfs are specified.

localrepo: make "undofiles()" return list of tuples "(vfs, relative filename)" Before this patch, "localrepository.undofiles()" returns list of absolute filename of undo files. This patch makes it return list of tuples "(vfs, relative filename)" to access undo files via vfs. This patch also changes "repair.strip()", which is the only user of "localrepository.undofiles()".

exchange: fix pyflakes import complaint

hgweb: override the charset attribute in the http request The default http request character set is UTF-8. If the message is not encoded in UTF-8, such as big5, it cannot be shown correctly. The 'charset' is overridden by the root document's, such that the user can select the proper encoding in the browser.

diff: use second filename for --stat reporting on git patches (issue4221)

exchange: drop useless line break

subrepo: check return code for git push (issue4223)

localrepo: add unbundle support Localrepo now supports the unbundle method of pushing changegroups. We plan to use the unbundle call for bundle2 so it is important that all peers supports it. The `peer.unbundle` and `peer.addchangegroup` code path have small difference so cause some test output changes. None of those changes seems problematic.

unbundle: extract the core logic in another function The `exchange` module now contains an `unbundle` function that holds the core unbundle logic. The wire protocol keeps its own unbundle function. It enforces wireprotocol-specific logic and then calls the extracted function. This aims at implementing unbundle for localrepo.

unbundle: extract checkheads in its own function We are going to refactor the unbundle function to have it working on a local repository too. Having this function extracted will ease the process. In the case of non-matching heads, the function now directly raises an exception. The top level of the function is catching it.

phase: apply publishing enforcement for "serve" source When a changegroup is added by a push on a publishing server, we ensure they are added as public. This is used to enforce publishing on server when the client is not aware of phases. It also prevents race conditions where a reader could see the changesets as draft before they get turned public by the client. Finally, this save rounds trip as the client does not need additional request to turn them public. However, this logic was only enforced when the changegroup was from a "push" source. And "push" is used for local pushes only. Wireprotocol push uses "serve" as source since Mercurial 1.9. We now enforce this logic for both "push" and "serve" sources. One could note that this logic was mainly useful during wireprotocol exchanges. So this code is finally put into good use, 9 versions after its introduction.

http: reuse authentication info after the first failed request (issue3567) [This was applied in 181108726ea5 but backed out again in af02783dea65 because of Python 2.4 issues. This edition and test-http.t works with Python 2.4.] Context: mercurial access to repository server with http access, and this server is protected by basic auth. Before patch: * mercurial try an anonymous access to server, server return 401 response and mercurial resend request with login / password information After patch: * mercurial try an anonymous access to server, server return 401 response. For all next requests, mercurial keep in memory this information (this server need basic auth information). This patch reduce the number of http access against mercurial server.

bundle2: use discard to remove bundle2 cap caps.remove('bundle2') was throwing an exception if bundle2 wasn't present in the capabilities. This was causing test-static-http.t to hang. Let's just use discard, so we don't get an exception.

statichttp: respect localrepo _restrictcapabilities The static http repository was doing his own filtering of capability ignoring the filtering done in the local repo main class. This led to static http using the current draft of bundle2. We now apply both.

tests: make unshelve tests more tricky - don't depend on size change One reason shelve and largefiles doesn't work could be rapidly changing standin files. Prove that shelve in general doesn't have problems with that.

shelve: introduce secret option for using fixed date for temporary commit Using a fixed date makes hashes stable and makes debugging simpler. The date and hashes of this changeset are normally not exposed.

mq: repo['.'] is not a wctx, repo[None] is The parameters passed to subrepo.submerge are confusing anyway.
