This script uses Documentation/config.txt as input for "git help --config" and "git config" completion but it misses the fact that config.txt includes other txt files. Include all *config.txt as input when scanning for config keys. This could produce false positives, but as long as we stick to the blah-config.txt naming convention, we should be ok.

2018-08-13range-diff: use dim/bold cues to improve dual color modeLibravatar Johannes Schindelin1-2/+4
It *is* a confusing thing to look at a diff of diffs. All too easy is it to mix up whether the -/+ markers refer to the "inner" or the "outer" diff, i.e. whether a `+` indicates that a line was added by either the old or the new diff (or both), or whether the new diff does something different than the old diff. To make things easier to process for normal developers, we introduced the dual color mode which colors the lines according to the commit diff, i.e. lines that are added by a commit (whether old, new, or both) are colored in green. In non-dual color mode, the lines would be colored according to the outer diff: if the old commit added a line, it would be colored red (because that line addition is only present in the first commit range that was specified on the command-line, i.e. the "old" commit, but not in the second commit range, i.e. the "new" commit). However, this dual color mode is still not making things clear enough, as we are looking at two levels of diffs, and we still only pick a color according to *one* of them (the outer diff marker is colored differently, of course, but in particular with deep indentation, it is easy to lose track of that outer diff marker's background color). Therefore, let's add another dimension to the mix. Still use green/red/normal according to the commit diffs, but now also dim the lines that were only in the old commit, and use bold face for the lines that are only in the new commit. That way, it is much easier not to lose track of, say, when we are looking at a line that was added in the previous iteration of a patch series but the new iteration adds a slightly different version: the obsolete change will be dimmed, the current version of the patch will be bold. At least this developer has a much easier time reading the range-diffs that way. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-08-08sideband: highlight keywords in remote sideband outputLibravatar Han-Wen Nienhuys1-0/+12
The colorization is controlled with the config setting "color.remote". Supported keywords are "error", "warning", "hint" and "success". They are highlighted if they appear at the start of the line, which is common in error messages, eg. ERROR: commit is missing Change-Id The Git push process itself prints lots of non-actionable messages (eg. bandwidth statistics, object counters for different phases of the process). This obscures actionable error messages that servers may send back. Highlighting keywords in the sideband draws more attention to those messages. The background for this change is that Gerrit does server-side processing to create or update code reviews, and actionable error messages (eg. missing Change-Id) must be communicated back to the user during the push. User research has shown that new users have trouble seeing these messages. The highlighting is done on the client rather than server side, so servers don't have to grow capabilities to understand terminal escape codes and terminal state. It also consistent with the current state where Git is control of the local display (eg. prefixing messages with "remote: "). The highlighting can be configured using color.remote.<KEYWORD> configuration settings. Since the keys are matched case insensitively, we match the keywords case insensitively too. Finally, this solution is backwards compatible: many servers already prefix their messages with "error", and they will benefit from this change without requiring a server update. By contrast, a server-side solution would likely require plumbing the TERM variable through the git protocol, so it would require changes to both server and client.

Change the handling of fetch.negotiationAlgorithm=<str> to error out on unknown strings, i.e. everything except "default" or "skipping". This changes the behavior added in 42cc7485a2 ("negotiator/skipping: skip commits during fetch", 2018-07-16) which would ignore all unknown values and silently fall back to the "default" value. For a feature like this it's much better to produce an error than proceed. We don't want users to debug some amazingly slow fetch that should benefit from "skipping", only to find that they'd forgotten to deploy the new git version on that particular machine.

Implement support for fetch.fsck.* corresponding with the existing receive.fsck.*. This allows for pedantically cloning repositories with specific issues without turning off fetch.fsckObjects. One such repository is https://github.com/robbyrussell/oh-my-zsh.git which before this change will emit this error when cloned with fetch.fsckObjects: error: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes fatal: Error in object fatal: index-pack failed Now with fetch.fsck.zeroPaddedFilemode=warn we'll warn about that issue, but the clone will succeed: warning: object 2b7227859263b6aabcc28355b0b994995b7148b6: zeroPaddedFilemode: contains zero-padded file modes warning: object a18c4d13c2a5fa2d4ecd5346c50e119b999b807d: zeroPaddedFilemode: contains zero-padded file modes warning: object 84df066176c8da3fd59b13731a86d90f4f1e5c9d: zeroPaddedFilemode: contains zero-padded file modes The motivation for this is to be able to turn on fetch.fsckObjects globally across a fleet of computers but still be able to manually clone various legacy repositories by either white-listing specific issues, or better yet whitelist specific objects. The use of --git-dir=* instead of -C in the tests could be considered somewhat archaic, but the tests I'm adding here are duplicating the corresponding receive.* tests with as few changes as possible.

The documentation for the fsck.<msg-id> and receive.fsck.<msg-id> variables was mostly duplicated in two places, with fsck.<msg-id> making no mention of the corresponding receive.fsck.<msg-id>, and the same for fsck.skipList. I spent quite a lot of time today wondering why setting the fsck.<msg-id> variant wasn't working to clone a legacy repository (not that that would have worked anyway, but a subsequent patch implements fetch.fsck.<msg-id>). Rectify this situation by describing the feature in general terms under the fsck.* documentation, and make the receive.fsck.* documentation refer to those variables instead. This documentation was initially added in 2becf00ff7 ("fsck: support demoting errors to warnings", 2015-06-22) and 4b55b9b479 ("fsck: document the new receive.fsck.<msg-id> options", 2015-06-22).

2018-07-18add core.usereplacerefs config optionLibravatar Jeff King1-0/+5
We can already disable replace refs using a command line option or environment variable, but those are awkward to apply universally. Let's add a config option to do the same thing. That raises the question of why one might want to do so universally. The answer is that replace refs violate the immutability of objects. For instance, if you wanted to cache the diff between commit XYZ and its parent, then in theory that never changes; the hash XYZ represents the total state. But replace refs violate that; pushing up a new ref may create a completely new diff. The obvious "if it hurts, don't do it" answer is not to create replace refs if you're doing this kind of caching. But for a site hosting arbitrary repositories, they may want to allow users to share replace refs with each other, but not actually respect them on the site (because the caching is more important than the replace feature).

2018-06-28upload-pack: implement ref-in-wantLibravatar Brandon Williams1-0/+7
Currently, while performing packfile negotiation, clients are only allowed to specify their desired objects using object ids. This causes a vulnerability to failure when an object turns non-existent during negotiation, which may happen if, for example, the desired repository is provided by multiple Git servers in a load-balancing arrangement and there exists replication delay. In order to eliminate this vulnerability, implement the ref-in-want feature for the 'fetch' command in protocol version 2. This feature enables the 'fetch' command to support requests in the form of ref names through a new "want-ref <ref>" parameter. At the conclusion of negotiation, the server will send a list of all of the wanted references (as provided by "want-ref" lines) in addition to the generated packfile.

2018-06-27gc: automatically write commit-graph filesLibravatar Derrick Stolee1-3/+6
The commit-graph file is a very helpful feature for speeding up git operations. In order to make it more useful, make it possible to write the commit-graph file during standard garbage collection operations. Add a 'gc.commitGraph' config setting that triggers writing a commit-graph file after any non-trivial 'git gc' command. Defaults to false while the commit-graph feature matures. We specifically do not want to have this on by default until the commit-graph feature is fully integrated with history-modifying features like shallow clones.

2018-06-25Merge branch 'nd/complete-config-vars'Libravatar Junio C Hamano1-1/+2
Continuing with the idea to programatically enumerate various pieces of data required for command line completion, teach the codebase to report the list of configuration variables subcommands care about to help complete them. * nd/complete-config-vars: completion: complete general config vars in two steps log-tree: allow to customize 'grafted' color completion: support case-insensitive config vars completion: keep other config var completion in camelCase completion: drop the hard coded list of config vars am: move advice.amWorkDir parsing back to advice.c advice: keep config name in camelCase in advice_config[] fsck: produce camelCase config key names help: add --config to list all available config fsck: factor out msg_id_info[] lazy initialization code grep: keep all colors in an array Add and use generic name->id mapping code for color slot parsing

2018-06-21Documentation/config.txt: camel-case lineNumber for consistencyLibravatar Taylor Blau1-1/+1
lineNumber has casing that is inconsistent with surrounding options, like color.grep.matchContext, and color.grep.matchSelected. Re-case this documentation in order to be consistent with the text around it, and to ensure that new entries are consistent, too.
