simple4server: option to advertise obsolescence support We had an option to control the advertising of the obsolescence markers support from the server. The goal of this option is to allow large scale repo hosting service to control the use of obsolescence markers exchange.

export: add test for simple4server We now officially test it over http

exchange: fix push markers over wire protocol for http peer Http actually interpret the data passed to _callpush expecting them to a bundle. Interpretation of a markers stream as a bundle obviously led to crash.

exchange: expose length of pushed markers http wireprotocol will need it.

simple4server: update "from <changeset>" statement Could obviously not do it in the same changeset than the original changes.

exchange: fix changeset pulling over http http compress its stream. The were building a bogus stream where the first 10 bytes where uncompressed. Confusing the client.

simple4server: update "from <changeset>" statement Could obviously not do it in the same changeset than the original changes.

exchange: properly wrap wireprotocol capabilities Just wrapping the module function only works for ssh. Ssh gets capability through the `hello` command. We also need to wrap the function stored in the command dict. This fix discovery for http peer.

simple4server: add origin and documentation to most function

evolve: add 2.9.1 compatibility seal to simple4server

simple4server: fix a missing import

evolve: update version compatibility error message

exchange: fix pull over wire protocol Actually hand pulled obsolescence markers to the pull logic. In the wire protocol case we did not reset the position of the file pointer after writing the pulled data. This lead the pull logic to thing that no markers were send at all. This changeset fix this client side bug. (apparently no test check both markers pulling and wireprotocol)

exchange: enforce permission on new wireprotocol command hgweb needs an explicit declaration of the permission level of each commands.

merge stable

evolve: fix typos in uncommit docstring

simple4server: add the wireproto command for obsolescence markers discovery This come with its usual train of duplicated utility.

discovery: use the discovery process for pull Wow! Such speed! Much functional! Very proof on concept implementation!

discovery: implement a discovery process and use it for push Much faster! So functional! Very proof on concept implementation! Wow!

discovery: first version of the "hash tree" idea We build a hash for each node based on the markers that applies to it and the hash of its parent. This will allow a kind of discovery process for markers.

evolve: update changelog with recent advance

merged 3.3 release into default Some of the default content was released in 3.3.0 the other ones are moved to 3.4

Added tag 3.3.0 for changeset 83882f2fbecb

prepare 3.3.0 release

evolve: drop `latercomer` and `conflicting` compatibility. Those old alias are deprecated for a long time now. All computations related to troubles are in Mercurial core for multiple versions.

evolve: use flag value from core for bumped fix This flag is available from core for a long time, lets use it directly from there. This commit intend to cleanup old stuff from the evolve extention.

test: get rid of all reference to conflicting changesets They are now called divergent for a long time.

merge various improvement to stable We want a good stable state before starting massive changes in default for obsolescence marker update.

exchange: add progress bar when pushing using wire protocol command Progress bar on pull was only available for pushkey based push before this changeset. This implementation is very hacky but we are still at a proof of concept stage for those new exchange method.

exchange: add progress bar when pulling using wire protocol command progress bar on pull was only available for pushkey based pull before this changeset.

exchange: automate the testing process too we now have: dotest TESTNAME [TARGETNODE]

exchange: have a function doing all the common initial setup This will help creation of further test.

exchance: add a common setup script for all test

exchange: add test case for A.2 Testcase defined here: http://mercurial.selenic.com/wiki/ObsolescenceMarkersExchange

exchange: add test case for A.1 Testcase defined here: http://mercurial.selenic.com/wiki/ObsolescenceMarkersExchange

exchange: add the pullmarker wireproto command to simple4server This will allow simple server side support. (yes, code duplication is bad I already told you I won't do it too much mom)

exchange: extract computation of pulled markers boundary in a function I expect massive experimentation on this specific aspect. so we better isolate it.

exchange: pull markers relevant to the pulled subset only With the command recently introduced we can select to pull only markers relevant to some nodes. We are now pull all markers for all node in the relevant subset. We'll try to pull less (just markers for node where local and remote marker diverge) later, but we need some marker discovery mechanism for that. which are not easy.

exchange: add a new method to pull markers It has both local and wire protocol implementation. This command does not requires escaping of the marker and are expecting to me highly faster than the pushkey method. The other main point is that command is to accept a `heads` and `common` argument to select to pull changeset only relevant to a set a of node. We are not using this capability yet but we'll do it soon

exchange: add the pushmarker wireproto command to simple4server This will allow simple server side support. (yes, code duplication is bad, I won't do it too much mom)

exchange: introduce a wireprotocol command to push markers Pushkey is not adapted to transmit a stream of binary data. We used it as a hack so far. We add a new wire protocol command to speed the things up (and also push all the markers in a single transaction). The proper way to do it is to introduce bundle2 in core, but this will already help in the mean time.

exchange: actually use _pushkeyescape fallback The code was still calling `obsolete._pushkeyescape` therefore never calling the fallback we defined. Now that we call it, it had to be fixed to actually work too.

merge with stable

prune: accept '0 0' as a valide --date value I 've no idea why 4c0f6d555032 introduced it with this check.

exchange: only push the set of marker relevant to want we push We now compute all markers relevant to pushed set. And just send just those one. So you are no longer pushing markers that point to changeset your are not pushing. See the in line comment for details about what "relevant" is. Multiple nice output have been added in the process.

evolve: add relevant marker exchange machinery This is going to be needed for obsolescence marker exchange.

fastobs: rename var from `node` to `rev` It contains revision (from repo.revs not node).

fastobs: move the extension to the hgext dir

test-prune: update test with a prune output compatible with newest hg Newest hg can record the parent information in the marker. This change the debugobsstorestate output a lot.

drophack: major speedup to marker stripping It appear that each call to obsstore.add have a significant overhead (in particular the creation of a set form the list of markers and file system operation to the obsstore file. We now compute the marker we need to store and write them in a single call.

evolve: add a cmddebugrecordpruneparents command This command can be used to create prune marker with parent information from prune marker on changeset known locally.

debugobsstorestat: add test for pruning There is multiple prune specific code in this command. So we test it in the presence of prun marker too.

debugobsstorestat: add information about cluster We now display information about independant osolescence markers clusters.

evolve: fix creation of prunedchildren for merge The `p2` code path was broken. (stupid typo)

evolve: add a debugobsstorestat command This commands print multiple some data about the content of the obsstore. This will be usefull to provide some metric and insight for obsolescence marker exchange.

evolve: extend obsstore object to use prune parent information Now that we have the information, we can use it to build a mapping to access all marker that prune a children of a node. This is similar to what we do for successors and precursors. The performance impact is a few tens of second on my mercurial clone. Experimenting is worth the trouble.

prune: wrap mercurial internal to add parent information in prune marker We store as a p1 (and p2) key in the extra dict for marker. This allow us to record this information for future use without requiering a format change.

evolve: drop `latercomer` and `conflicting` compatibility. Those old alias are deprecated for a long time now. All computations related to troubles are in Mercurial core for multiple versions.

test: get rid of all reference to conflicting changesets They are now called divergent for a long time.

evolve: use flag value from core for bumped fix This flag is available from core for a long time, lets use it directly from there. This commit intend to cleanup old stuff from the evolve extention.

importing fastop extension in this repo This repo is dedicated to experimentation on mutable history topic. Fastop is appropriate there.

fastobs: revset refactor related fixes

adapt fastopt extension to mercurial.exchange module The push code have changed to be more modular. the fastop extension need to be rewritten. No backward compatibility preserved for mercurial <=2.9x.

drop unused function `pushmarkerwrapper` I can find any user for this function.

Add initial test.

Deduplicate markers. Depends on __hash__ and __eq__ on obsolete.marker

copy precursor revset from evolve so we don't depend on involve

fastobs: details strategies in the main help

fastobs: fix a bunch of stupid errors that prevented it from working at all

fastobs: clean up logging a little

fastobs: first commit of an extension to test obsolete marker exchange methods This currently implements the "fill in the box" approach discussed at the 2.6 sprint, which seems to handle common cases correctly with significantly less data transferred.

drophack: add a new drop hack extension for Matt Mackall usage This extension is hacky and not intended for real world usage. See documentation for details.

prune: add biject option This option allows two ranges to be given for successors and precursors such that there is a one-to-one match between each range. Test coverage has been added.

evolve: register a summary hook instead of wrapping the summary command

merge stable into default.
