This feature is intended to support working with legacy + repositories containing such data. ++ +Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but +to accept pushes of such data set `receive.fsck.<msg-id>` instead, or +to clone or fetch it set `fetch.fsck.<msg-id>`. ++ +The rest of the documentation discusses `fsck.*` for brevity, but the +same applies for the corresponding `receive.fsck.*` and +`fetch.<msg-id>.*`. variables. ++ +Unlike variables like `color.ui` and `core.editor` the +`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not +fall back on the `fsck.<msg-id>` configuration if they aren't set. To +uniformly configure the same fsck settings in different circumstances +all three of them they must all set to the same values. ++ +When `fsck.<msg-id>` is set, errors can be switched to warnings and +vice versa by configuring the `fsck.<msg-id>` setting where the +`<msg-id>` is the fsck message ID and the value is one of `error`, +`warn` or `ignore`. For convenience, fsck prefixes the error/warning +with the message ID, e.g. "missingEmail: invalid author/committer +line - missing email" means that setting `fsck.missingEmail = ignore` +will hide that issue. ++ +In general, it is better to enumerate existing objects with problems +with `fsck.skipList`, instead of listing the kind of breakages these +problematic objects share to be ignored, as doing the latter will +allow new instances of the same breakages go unnoticed. ++ +Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but +doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` +will only cause git to warn. + +fsck.skipList:: + The path to a list of object names (i.e. one unabbreviated SHA-1 per + line) that are known to be broken in a non-fatal way and should + be ignored. On versions of Git 2.20 and later comments ('#'), empty + lines, and any leading and trailing whitespace is ignored. Everything + but a SHA-1 per line will error out on older versions. ++ +This feature is useful when an established project should be accepted +despite early commits containing errors that can be safely ignored +such as invalid committer email addresses. Note: corrupt objects +cannot be skipped with this setting. ++ +Like `fsck.<msg-id>` this variable has corresponding +`receive.fsck.skipList` and `fetch.fsck.skipList` variants. ++ +Unlike variables like `color.ui` and `core.editor` the +`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not +fall back on the `fsck.skipList` configuration if they aren't set. To +uniformly configure the same fsck settings in different circumstances +all three of them they must all set to the same values. ++ +Older versions of Git (before 2.20) documented that the object names +list should be sorted. This was never a requirement, the object names +could appear in any order, but when reading the list we tracked whether +the list was sorted for the purposes of an internal binary search +implementation, which could save itself some work with an already sorted +list. Unless you had a humongous list there was no reason to go out of +your way to pre-sort the list. After Git version 2.20 a hash implementation +is used instead, so there's now no reason to pre-sort the list. |
