2018-08-13cat-file: support "unordered" output for --batch-all-objectsLibravatar Jeff King1-0/+10
If you're going to access the contents of every object in a packfile, it's generally much more efficient to do so in pack order, rather than in hash order. That increases the locality of access within the packfile, which in turn is friendlier to the delta base cache, since the packfile puts related deltas next to each other. By contrast, hash order is effectively random, since the sha1 has no discernible relationship to the content. This patch introduces an "--unordered" option to cat-file which iterates over packs in pack-order under the hood. You can see the results when dumping all of the file content: $ time ./git cat-file --batch-all-objects --buffer --batch | wc -c 6883195596 real 0m44.491s user 0m42.902s sys 0m5.230s $ time ./git cat-file --unordered \ --batch-all-objects --buffer --batch | wc -c 6883195596 real 0m6.075s user 0m4.774s sys 0m3.548s Same output, different order, way faster. The same speed-up applies even if you end up accessing the object content in a different process, like: git cat-file --batch-all-objects --buffer --batch-check | grep blob | git cat-file --batch='%(objectname) %(rest)' | wc -c Adding "--unordered" to the first command drops the runtime in git.git from 24s to 3.5s. Side note: there are actually further speedups available for doing it all in-process now. Since we are outputting the object content during the actual pack iteration, we know where to find the object and could skip the extra lookup done by oid_object_info(). This patch stops short of that optimization since the underlying API isn't ready for us to make those sorts of direct requests. So if --unordered is so much better, why not make it the default? Two reasons: 1. We've promised in the documentation that --batch-all-objects outputs in hash order. Since cat-file is plumbing, people may be relying on that default, and we can't change it. 2. It's actually _slower_ for some cases. We have to compute the pack revindex to walk in pack order. And our de-duplication step uses an oidset, rather than a sort-and-dedup, which can end up being more expensive. If we're just accessing the type and size of each object, for example, like: git cat-file --batch-all-objects --buffer --batch-check my best-of-five warm cache timings go from 900ms to 1100ms using --unordered. Though it's possible in a cold-cache or under memory pressure that we could do better, since we'd have better locality within the packfile. And one final question: why is it "--unordered" and not "--pack-order"? The answer is again two-fold: 1. "pack order" isn't a well-defined thing across the whole set of objects. We're hitting loose objects, as well as objects in multiple packs, and the only ordering we're promising is _within_ a single pack. The rest is apparently random. 2. The point here is optimization. So we don't want to promise any particular ordering, but only to say that we will choose an ordering which is likely to be efficient for accessing the object content. That leaves the door open for further changes in the future without having to add another compatibility option.

2018-08-13range-diff: use dim/bold cues to improve dual color modeLibravatar Johannes Schindelin2-6/+17
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>

2018-08-13Introduce `range-diff` to compare iterations of a topic branchLibravatar Johannes Schindelin1-0/+10
This command does not do a whole lot so far, apart from showing a usage that is oddly similar to that of `git tbdiff`. And for a good reason: the next commits will turn `range-branch` into a full-blown replacement for `tbdiff`. At this point, we ignore tbdiff's color options, as they will all be implemented later using diff_options. Since f318d739159 (generate-cmds.sh: export all commands to command-list.h, 2018-05-10), every new command *requires* a man page to build right away, so let's also add a blank man page, too.

2018-08-09repack: repack promisor objects if -a or -A is setLibravatar Jonathan Tan1-0/+5
Currently, repack does not touch promisor packfiles at all, potentially causing the performance of repositories that have many such packfiles to drop. Therefore, repack all promisor objects if invoked with -a or -A. This is done by an additional invocation of pack-objects on all promisor objects individually given, which takes care of deduplication and allows the resulting packfiles to respect flags such as --max-pack-size.

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.

The following phrase could be interpreted multiple ways: "To pretend you have a file with mode and sha1 at path" In particular, I can think of two: 1. Pretend we have some new file, which happens to have a given mode and sha1 2. Pretend one of the files we are already tracking has a different mode and sha1 than what it really does I think people could easily assume either case while reading, but the example command provided doesn't actually handle the first case, which caused some minor frustration to at least one user. Modify the example command so that it correctly handles both cases, and re-order the wording in a way that makes it more likely folks will assume the first interpretation. I believe the new example shouldn't pose any obstacles to those wanting the second interpretation (at worst, they pass an unnecessary extra flag).

2018-08-07doc hash-function-transition: pick SHA-256 as NewHashLibravatar Jonathan Nieder1-98/+98
From a security perspective, it seems that SHA-256, BLAKE2, SHA3-256, K12, and so on are all believed to have similar security properties. All are good options from a security point of view. SHA-256 has a number of advantages: * It has been around for a while, is widely used, and is supported by just about every single crypto library (OpenSSL, mbedTLS, CryptoNG, SecureTransport, etc). * When you compare against SHA1DC, most vectorized SHA-256 implementations are indeed faster, even without acceleration. * If we're doing signatures with OpenPGP (or even, I suppose, CMS), we're going to be using SHA-2, so it doesn't make sense to have our security depend on two separate algorithms when either one of them alone could break the security when we could just depend on one. So SHA-256 it is. Update the hash-function-transition design doc to say so. After this patch, there are no remaining instances of the string "NewHash", except for an unrelated use from 2008 as a variable name in t/t9700/test.pl.

2018-08-06add a script to diff rendered documentationLibravatar Jeff King2-0/+110
After making a change to the documentation, it's easy to forget to check the rendered version to make sure it was formatted as you intended. And simply doing a diff between the two built versions is less trivial than you might hope: - diffing the roff or html output isn't particularly readable; what we really care about is what the end user will see - you have to tweak a few build variables to avoid spurious differences (e.g., version numbers, build times) Let's provide a script that builds and installs the manpages for two commits, renders the results using "man", and diffs the result. Since this is time-consuming, we'll also do our best to avoid repeated work, keeping intermediate results between runs. Some of this could probably be made a little less ugly if we built support into Documentation/Makefile. But by relying only on "make install-man" working, this script should work for generating a diff between any two versions, whether they include this script or not.
