This is a follow up from the patch series called "odb remote" that I
sent earlier this year, which was itself a follow up from the patch
series called "Promisor remotes and external ODB support" that I sent
earlier this year, which was itself a follow up from previous series.
See the links section for more information.
Following discussions of the previous patch series, the mechanism is
renamed from "odb remote" to "remote odb". I hope that this will will
be the last name change.
As with the previous "odb remote" series, this series is only about
integrating with the promisor/narrow clone work and showing that it
makes it possible to use more than one promisor remote. Everything
that is not necessary for that integration has been removed for now
(though you can still find it in one of my branches on GitHub if you
want).
There is one test in patch 8/9 that shows that more than one promisor
remote can now be used, but I still feel that it could be interesting
to add other such tests, so I am open to ideas in this area.
Changes compared to previous patch series
- big rename from "odb remote" to "remote odb"
- rename of field from "dealer" to "remote" in struct odb_helper
- add comments around struct odb_helper
- improve a few commit messages
- add a documentation patch
High level overview of this patch series
- Patch 1/9:
This makes functions in fetch-object.c return an error code, which is
necessary to later tell that they failed and try another remote odb
when there is more than one. This could also just be seen as a fix to
these functions.
- Patch 2/9:
This introduces the minimum infrastructure for remote odbs.
- Patches 3/9 and 4/9:
These patches implement remote_odb_get_direct() and
remote_odb_get_many_direct() using the functions from fetch-object.c.
These new functions will be used in following patches to replace the
functions from fetch-object.c.
- Patch 5/9:
This implement remote_odb_reinit() which will be needed to reparse the
remote odb configuration.
- Patches 6/9 and 7/9:
These patches integrate the remote odb mechanism into the
promisor/narrow clone code. The "extensions.partialclone" config
option is replaced by "odb..promisorRemote" and
"core.partialclonefilter" is replaced by
"odb..partialclonefilter".
- Patch 8/9:
This adds a test case that shows that now more than one promisor
remote can be used.
- Patch 9/9:
This starts documenting the remote odb mechanism.
Discussion
~~
I am not sure that it is ok to completely replace the
"extensions.partialclone" config option. Even if it is fully replaced,
no "extensions.remoteodb" is implemented in these patches, as maybe
the "extensions.partialclone" name could be kept even if the
underlying mechanism is the remote odb mechanism.
Anyway I think that the remote odb mechanism is much more extensible,
so I think using "extensions.partialclone" to specify a promisor
remote should be at least deprecated.
