Before this patch, when ACL is involved, narrowspecs are send as bundle2 parameter for narrow:spec bundle2 part. The limitation of bundle2 parts are they cannot send data larger than 255 bytes. Includes and excludes in narrow are not limited by size and they can grow over 255 bytes. This patch introduces a new mandatory bundle2 part and send narrowspecs as data of that. The new bundle2 part is introduced to keep things cleaner and easy to distinguish related to backward compatibility. The part is mandatory because without server's narrowspec, the local ACL narrow repo won't work. This patch makes clients compatible with servers which have older versions. However I left a comment that we should drop the other bundle2 part soon as that's broken and people should not rely on that. I named the new bundle2 part 'Narrow:responsespec' because: 1) Capital 'N' to make it mandatory 2) 'Narrow:spec' cannot be used because bundle2 enforces that there should not be two different parts which resolve to same name when lowercased. 3) reponsespec clears that they are specs which are send as reponse by the server While I was here, I renamed `narrowhgacl` section to `narrowacl` as suggested by idlsoft@ and martinvonz@.

overlayworkingctx class is used to do in-memory merging. The data() function of that class has logic to look for data() in the wrappedctx if the file data in cache is empty and if the file is dirty. This assumes that if a file is dirty and cache has empty data for it, it will exists in the _wrappedctx. However this assumption can be False in case when we are merging a file which is empty in destination. In these cases, the backup file 'foo.orig' created by our internal merge algorithms will be empty, however it won't be present in _wrappedctx. This case will lead us to error like the one this patch is fixing. Let's only fallback to getting data from wrappedctx if cache has 'None' as data.

When building rpm packages for centos 5 and 6, we bundle a mercurial-specific version of Python 2.7 in /opt/python-hg. This change is analogous to 5e947367606c, and bumps the embedded Python version from 2.7.14 (released in 2017) to 2.7.16 (latest as of today).

We now have beta support for Python 3. In my opinion, it isn't yet stable enough to allow `pip install Mercurial` to work with Python 3 out of the box: we don't want people accidentally using Mercurial with Python 3 just yet. But I do think we should be more friendly about informing people of their options. This commit tweaks the error message that users see when running setup.py with Python 3. We instruct them about the current level of Python 3 support, point them at the wiki for more info, and give them instructions on how to bypass the check. As part of this, I also changed which version value is printed, as we were printing a named tuple before.

Yuya observed in a recent review that it is worthwhile to keep setup.py parseable with Python 2.6 so a useful error message is seen when attempting to run with Python 2.6. This commit removes a set and dict comprehension so setup.py is parseable with Python 2.6.

Our in-repo py2exe packaging code uses virtualenvs for managing dependencies. An advantage of this is that packaging is more deterministic and reproducible. Without virtualenvs, we need to install packages in the system Python install. Packages installed by other consumers of the system Python could leak into the Mercurial package. A regression from this change was that py2exe packages contained the virtualenv's hacked distutils modules instead of the original distutils modules. (virtualenv installs a hacked distutils module because distutils uses relative path lookups that fail when running from a virtualenv.) This commit introduces a workaround so py2exe packaging uses the original distutils modules when running from a virtualenv. With this change, `import distutils` no longer fails from py2exe builds produced from a virtualenv. This fixes the regression. Furthermore, we now include all distutils modules. Before, py2exe's module finding would only find modules there were explicitly referenced in code. So, we now package a complete copy of distutils instead of a partial one. This is even better than before. # no-check-commit foo_bar function name

We already displayed information about heads of the common set that are either local or remote heads. We now also do so for heads of the common set that are both local and remote heads too. This is useful because various step in the set discovery algorithm have head specific optimizations.

For trivial cases, the cost of the verify run after `hg recover` is getting in the way. In addition for very large repositories, the cost is simply too high to be paid, making `hg recover` an unusable commands. We introduce a --verify flag, set by default. If is automatically associated with a --no-verify flag that one can use to skip the verify step. We might consider changing the default behavior in the future. However this is out of scope for this series.

_forwardchunks is used to compensate for getbundle protocol deficits. Since it transparently decodes the payload, it also needs to remove the corresponding compression parameter in case the server decides to send one. This the wire protocol part of issue 5990.

This introduces a config option that lets you choose to write copy metadata to the changeset extras instead of to filelog. There's also an option to write it to both places. I imagine that may possibly be useful when transitioning an existing repo. The copy metadata is stored as two fields in extras: one for copies since p1 and one for copies since p2. I may need to add more information later in order to make copy tracing faster. Specifically, I'm thinking out recording which files were added or removed so that copies._chaincopies() doesn't have to look at the manifest for that. But that would just be an optimization and that can be added once we know if it's necessary. I have also considered saving space by using replacing the destination file path by an index into the "files" list, but that can also be changed later (but before the feature is ready to release).

Ideally, the non-experimental version of `experimental.extra-filter-revs` will cover the use case for `server.view=immutable` well enough than having to have this dedicated configuration. Since `server.view` is not part of any release, I would prefer to have it marked as experimental to avoid having it to support it for ever.

This requirement supersedes `exp-compression-zstd`. However, we keep support for the old requirement. Strictly speaking, we do not need to add a new requirement, there are no logic change making "new" repo incompatible with mercurial client using a version that support `exp-compression-zstd`. The choice to introduce a new requirement is motivated by the following: * The previous requirement was explicitly "experimental". Using it by default could confuse users. * adding support for a hypothetical third compression engine will requires new code, and will comes with its own requirement tool. * We won't use it as the default for a while since I do not think we support zstd on all platform. I can imagine we'll gain another (unrelated but on my default) requirement by the time we turn this zstd by default.

When running `hg pull --update`, the update step may fail. Nothing in the error message help to understand the abort is related to the secondary step (update) instead of the primary step (pull). We now add some information to the error message to clarify it comes from the update part. It is useful in various situation (uncommitted changes blocking the update, update to hidden destination, etc...) The pull output is updated from: $ hg pull ../repo-Bob --rev 956063ac4557 --update pulling from ../repo-Bob searching for changes adding changesets adding manifests adding file changes added 2 changesets with 0 changes to 2 files (+1 heads) (2 other changesets obsolete on arrival) abort: filtered revision '6'! to: $ hg pull ../repo-Bob --rev 956063ac4557 --update pulling from ../repo-Bob searching for changes adding changesets adding manifests adding file changes added 2 changesets with 0 changes to 2 files (+1 heads) (2 other changesets obsolete on arrival) abort: cannot update to target: filtered revision '6'! (I am not sure why the actual error, "filtered revision '6'", is not using the more modern format mentioning the obsolescence fate of '6')

Nowadays, it is possible to explicitly pull a remote revision that end up being hidden locally (eg: obsoleted locally). However before this patch, some internal processing where crashing trying to resolve a filtered revision. Without this patches, the pull output result a confusing output: $ hg pull ../repo-Bob --rev 956063ac4557 pulling from ../repo-Bob searching for changes adding changesets adding manifests adding file changes added 2 changesets with 0 changes to 2 files (+1 heads) (2 other changesets obsolete on arrival) abort: 00changelog.i@956063ac4557828781733b2d5677a351ce856f59: filtered node!

For the same reason we want to keep the cache for the `served` view up to date, we want to also keep the `served.hidden` view up to date. If some processes with a readonly access to the repo needs to access it, we better have the cache warm to avoid computing the same data over and over and over. In most case (no secret changesets), the "served" and "served.hidden" set will be identical and no cache will actually have to be updated.

There are multiple usecase for being able to explicitly view or pull obsolete from a server. We need to be able to do so without exposing the secret changesets. We introduces a dedicated repository "view" to do so. Way to expose this "view" to the user will come later. To keep a behavior consistent with expected client/server behavior, the general idea is for the obsolete access to be explicitly requested by the code generating the request. In addition, the will be server side configuration to restrict the access to this feature.

The conditional could lead to wrong computation since we have more unserved changesets than just the "secret" phase. In addition, now that we have efficient caching of phased changesets, we don't need the conditional anymore.

The above are the numbers of perfbranchmapload which shows how much time we saved by not validating the nodes. But we need to validate some nodes. Following are timings of some mercurial operations which have speed up because of this lazy validation of nodes: No-op `hg update` on our internal repository (Avg on 4 runs): Before: 0.540 secs After: 0.430 secs Setting a branch name which already exists without --force (Avg of 4 runs): Before: 0.510 secs After: 0.250 secs I ran the ASV performance suite and was unable to see any improvements except there was improvement of perfdirstatewrite() on netbeans which I think was not related. I looked into the commit code, the command which I am trying to speedup, it looks like it uses revbranchcache to update the branchcache. Differential Revision: https://phab.mercurial-scm.org/D6208
