"""remotefilelog causes Mercurial to lazilly fetch file contents (EXPERIMENTAL)
|
|
|
|
|
|
This extension is HIGHLY EXPERIMENTAL. There are NO BACKWARDS COMPATIBILITY
|
|
|
GUARANTEES. This means that repositories created with this extension may
|
|
|
only be usable with the exact version of this extension/Mercurial that was
|
|
|
used. The extension attempts to enforce this in order to prevent repository
|
|
|
corruption.
|
|
|
|
|
|
remotefilelog works by fetching file contents lazily and storing them
|
|
|
in a cache on the client rather than in revlogs. This allows enormous
|
|
|
histories to be transferred only partially, making them easier to
|
|
|
operate on.
|
|
|
|
|
|
Configs:
|
|
|
|
|
|
``packs.maxchainlen`` specifies the maximum delta chain length in pack files
|
|
|
|
|
|
``packs.maxpacksize`` specifies the maximum pack file size
|
|
|
|
|
|
``packs.maxpackfilecount`` specifies the maximum number of packs in the
|
|
|
shared cache (trees only for now)
|
|
|
|
|
|
``remotefilelog.backgroundprefetch`` runs prefetch in background when True
|
|
|
|
|
|
``remotefilelog.bgprefetchrevs`` specifies revisions to fetch on commit and
|
|
|
update, and on other commands that use them. Different from pullprefetch.
|
|
|
|
|
|
``remotefilelog.gcrepack`` does garbage collection during repack when True
|
|
|
|
|
|
``remotefilelog.nodettl`` specifies maximum TTL of a node in seconds before
|
|
|
it is garbage collected
|
|
|
|
|
|
``remotefilelog.repackonhggc`` runs repack on hg gc when True
|
|
|
|
|
|
``remotefilelog.prefetchdays`` specifies the maximum age of a commit in
|
|
|
days after which it is no longer prefetched.
|
|
|
|
|
|
``remotefilelog.prefetchdelay`` specifies delay between background

|
prefetches in seconds after operations that change the working copy parent
|
|
|
|
|
|
``remotefilelog.data.gencountlimit`` constraints the minimum number of data
|
|
|
pack files required to be considered part of a generation. In particular,
|
|
|
minimum number of packs files > gencountlimit.
|
|
|
|
|
|
``remotefilelog.data.generations`` list for specifying the lower bound of
|
|
|
each generation of the data pack files. For example, list ['100MB','1MB']
|
|
|
or ['1MB', '100MB'] will lead to three generations: [0, 1MB), [
|
|
|
1MB, 100MB) and [100MB, infinity).
|
|
|
|
|
|
``remotefilelog.data.maxrepackpacks`` the maximum number of pack files to
|
|
|
include in an incremental data repack.
|
|
|
|
|
|
``remotefilelog.data.repackmaxpacksize`` the maximum size of a pack file for
|
|
|
it to be considered for an incremental data repack.
|
|
|
|
|
|
``remotefilelog.data.repacksizelimit`` the maximum total size of pack files
|
|
|
to include in an incremental data repack.
|
|
|
|
|
|
``remotefilelog.history.gencountlimit`` constraints the minimum number of
|
|
|
history pack files required to be considered part of a generation. In
|
|
|
particular, minimum number of packs files > gencountlimit.
|
|
|
|
|
|
``remotefilelog.history.generations`` list for specifying the lower bound of
|
|
|
each generation of the history pack files. For example, list [
|
|
|
'100MB', '1MB'] or ['1MB', '100MB'] will lead to three generations: [
|
|
|
0, 1MB), [1MB, 100MB) and [100MB, infinity).
|
|
|
|
|
|
``remotefilelog.history.maxrepackpacks`` the maximum number of pack files to
|
|
|
include in an incremental history repack.
|
|
|
|

|
|
|
``remotefilelog.debug`` turn on remotefilelog-specific debug output
|
|
|
|
|
|
``remotefilelog.excludepattern`` pattern of files to exclude from pulls
|
|
|
|
|
|
``remotefilelog.includepattern`` pattern of files to include in pulls
|
|
|
|
|
|
``remotefilelog.fetchwarning``: message to print when too many
|
|
|
