"text" (i.e. be subjected to the autocrlf mechanism) is
decided purely based on the contents.
+ core.safecrlf::
+ If true, makes git check if converting `CRLF` as controlled by
+ `core.autocrlf` is reversible. Git will verify if a command
+ modifies a file in the work tree either directly or indirectly.
+ For example, committing a file followed by checking out the
+ same file should yield the original file in the work tree. If
+ this is not the case for the current setting of
+ `core.autocrlf`, git will reject the file. The variable can
+ be set to "warn", in which case git will only warn about an
+ irreversible conversion but continue the operation.
+ +
+ CRLF conversion bears a slight chance of corrupting data.
+ autocrlf=true will convert CRLF to LF during commit and LF to
+ CRLF during checkout. A file that contains a mixture of LF and
+ CRLF before the commit cannot be recreated by git. For text
+ files this is the right thing to do: it corrects line endings
+ such that we have only LF line endings in the repository.
+ But for binary files that are accidentally classified as text the
+ conversion can corrupt data.
+ +
+ If you recognize such corruption early you can easily fix it by
+ setting the conversion type explicitly in .gitattributes. Right
+ after committing you still have the original file in your work
+ tree and this file is not yet corrupted. You can explicitly tell
+ git that this file is binary and git will handle the file
+ appropriately.
+ +
+ Unfortunately, the desired effect of cleaning up text files with
+ mixed line endings and the undesired effect of corrupting binary
+ files cannot be distinguished. In both cases CRLFs are removed
+ in an irreversible way. For text files this is the right thing
+ to do because CRLFs are line endings, while for binary files
+ converting CRLFs corrupts data.
+ +
+ Note, this safety check does not mean that a checkout will generate a
+ file identical to the original file for a different setting of
+ `core.autocrlf`, but only for the current one. For example, a text
+ file with `LF` would be accepted with `core.autocrlf=input` and could
+ later be checked out with `core.autocrlf=true`, in which case the
+ resulting file would contain `CRLF`, although the original file
+ contained `LF`. However, in both work trees the line endings would be
+ consistent, that is either all `LF` or all `CRLF`, but never mixed. A
+ file with mixed line endings would be reported by the `core.safecrlf`
+ mechanism.
+
core.symlinks::
If false, symbolic links are checked out as small plain files that
contain the link text. linkgit:git-update-index[1] and
so that linkgit:git-pull[1] will appropriately merge from that
remote branch. Note that even if this option is not set,
this behavior can be chosen per-branch using the `--track`
- and `--no-track` options. This option defaults to false.
+ and `--no-track` options. This option defaults to true.
branch.<name>.remote::
When in branch <name>, it tells `git fetch` which remote to fetch.
whenever the corresponding pack is larger than 2 GB. Otherwise
the default is 1.
+pack.packSizeLimit:
+ The default maximum size of a pack. This setting only affects
+ packing to a file, i.e. the git:// protocol is unaffected. It
+ can be overridden by the `\--max-pack-size` option of
+ linkgit:git-repack[1].
+
pull.octopus::
The default merge strategy to use when pulling multiple branches
at once.
