From this release, + we started to discourage its uses and hint people about + filter-repo. + +UI, Workflows & Features + + * We now have an active interim maintainer for the Git-Gui part of + the system. Praise and thank Pratyush Yadav for volunteering. + + * The command line parser learned "--end-of-options" notation; the + standard convention for scripters to have hardcoded set of options + first on the command line, and force the command to treat end-user + input as non-options, has been to use "--" as the delimiter, but + that would not work for commands that use "--" as a delimiter + between revs and pathspec. + + * A mechanism to affect the default setting for a (related) group of + configuration variables is introduced. + + * "git fetch" learned "--set-upstream" option to help those who first + clone from their private fork they intend to push to, add the true + upstream via "git remote add" and then "git fetch" from it. + + * Device-tree files learned their own userdiff patterns. + (merge 3c81760bc6 sb/userdiff-dts later to maint). + + * "git rebase --rebase-merges" learned to drive different merge + strategies and pass strategy specific options to them. + + * A new "pre-merge-commit" hook has been introduced. + + * Command line completion updates for "git -c var.name=val" have been + added. + + * The lazy clone machinery has been taught that there can be more + than one promisor remote and consult them in order when downloading + missing objects on demand. + + * The list-objects-filter API (used to create a sparse/lazy clone) + learned to take a combined filter specification. + + * The documentation and tests for "git format-patch" have been + cleaned up. + + * On Windows, the root level of UNC share is now allowed to be used + just like any other directory. + + * The command line completion support (in contrib/) learned about the + "--skip" option of "git revert" and "git cherry-pick". + + * "git rebase --keep-base <upstream>" tries to find the original base + of the topic being rebased and rebase on top of that same base, + which is useful when running the "git rebase -i" (and its limited + variant "git rebase -x"). + + The command also has learned to fast-forward in more cases where it + can instead of replaying to recreate identical commits. + + * A configuration variable tells "git fetch" to write the commit + graph after finishing. + + * "git add -i" has been taught to show the total number of hunks and + the hunks that has been processed so far when showing prompts. + + +Performance, Internal Implementation, Development Support etc. + + * The code to write commit-graph over given commit object names has + been made a bit more robust. + + * The first line of verbose output from each test piece now carries + the test name and number to help scanning with eyeballs. + + * Further clean-up of the initialization code. + + * xmalloc() used to have a mechanism to ditch memory and address + space resources as the last resort upon seeing an allocation + failure from the underlying malloc(), which made the code complex + and thread-unsafe with dubious benefit, as major memory resource + users already do limit their uses with various other mechanisms. + It has been simplified away. + + * Unnecessary full-tree diff in "git log -L" machinery has been + optimized away. + + * The http transport lacked some optimization the native transports + learned to avoid unnecessary ref advertisement, which has been + corrected. + + * Preparation for SHA-256 upgrade continues in the test department. + (merge 0c37c41d13 bc/hash-independent-tests-part-5 later to maint). + + * The memory ownership model of the "git fast-import" got + straightened out. + + * Output from trace2 subsystem is formatted more prettily now. + + * The internal code originally invented for ".gitignore" processing + got reshuffled and renamed to make it less tied to "excluding" and + stress more that it is about "matching", as it has been reused for + things like sparse checkout specification that want to check if a + path is "included". + + * "git stash" learned to write refreshed index back to disk. + + * Coccinelle checks are done on more source files than before now. + + * The cache-tree code has been taught to be less aggressive in + attempting to see if a tree object it computed already exists in + the repository. + + * The code to parse and use the commit-graph file has been made more + robust against corrupted input. + + * The hg-to-git script (in contrib/) has been updated to work with + Python

If your repo has 10\^5 +files and 10\^5 commits, but each commit only modifies 5 files, then +git-filter-branch will make you do 10\^10 modifications, despite only +having (at most) 5*10^5 unique blobs. + +* If you try and cheat and try to make git-filter-branch only work on +files modified in a commit, then two things happen + + ** you run into problems with deletions whenever the user is simply + trying to rename files (because attempting to delete files that + don't exist looks like a no-op; it takes some chicanery to remap + deletes across file renames when the renames happen via arbitrary + user-provided shell) + + ** even if you succeed at the map-deletes-for-renames chicanery, you + still technically violate backward compatibility because users are + allowed to filter files in ways that depend upon topology of + commits instead of filtering solely based on file contents or names + (though this has not been observed in the wild). + +* Even if you don't need to edit files but only want to e.g. rename or +remove some and thus can avoid checking out each file (i.e. you can use +--index-filter), you still are passing shell snippets for your filters. +This means that for every commit, you have to have a prepared git repo +where those filters can be run. That's a significant setup. + +* Further, several additional files are created or updated per commit by +git-filter-branch. Some of these are for supporting the convenience +functions provided by git-filter-branch (such as map()), while others +are for keeping track of internal state (but could have also been +accessed by user filters; one of git-filter-branch's regression tests +does so). This essentially amounts to using the filesystem as an IPC +mechanism between git-filter-branch and the user-provided filters. +Disks tend to be a slow IPC mechanism, and writing these files also +effectively represents a forced synchronization point between separate +processes that we hit with every commit. + +* The user-provided shell commands will likely involve a pipeline of +commands, resulting in the creation of many processes per commit. +Creating and running another process takes a widely varying amount of +time between operating systems, but on any platform it is very slow +relative to invoking a function. + +* git-filter-branch itself is written in shell, which is kind of slow. +This is the one performance issue that could be backward-compatibly +fixed, but compared to the above problems that are intrinsic to the +design of git-filter-branch, the language of the tool itself is a +relatively minor issue. + + ** Side note: Unfortunately, people tend to fixate on the + written-in-shell aspect and periodically ask if git-filter-branch + could be rewritten in another language to fix the performance + issues. Not only does that ignore the bigger intrinsic problems + with the design, it'd help less than you'd expect: if + git-filter-branch itself were not shell, then the convenience + functions (map(), skip_commit(), etc) and the `--setup` argument + could no longer be executed once at the beginning of the program + but would instead need to be prepended to every user filter (and + thus re-executed with every commit). + +The https://github.com/newren/git-filter-repo/[git filter-repo] tool is +an alternative to git-filter-branch which does not suffer from these +performance problems or the safety problems (mentioned below). For those +with existing tooling which relies upon git-filter-branch, 'git +repo-filter' also provides +https://github.com/newren/git-filter-repo/blob/master/contrib/filter-repo-demos/filter-lamely[filter-lamely], +a drop-in git-filter-branch replacement (with a few caveats). While +filter-lamely suffers from all the same safety issues as +git-filter-branch, it at least ameloriates the performance issues a +little. + +[[SAFETY]] +SAFETY +------ + +git-filter-branch is riddled with gotchas resulting in various ways to +easily corrupt repos or end up with a mess worse than what you started +with: + +* Someone can have a set of "working and tested filters" which they +document or provide to a coworker, who then runs them on a different OS +where the same commands are not working/tested (some examples in the +git-filter-branch manpage are also affected by this). BSD vs. GNU +userland differences can really bite. If lucky, error messages are +spewed. But just as likely, the commands either don't do the filtering +requested, or silently corrupt by making some unwanted change. The +unwanted change may only affect a few commits, so it's not necessarily +obvious either. (The fact that problems won't necessarily be obvious +means they are likely to go unnoticed until the rewritten history is in +use for quite a while, at which point it's really hard to justify +another flag-day for another rewrite.) + +* Filenames with spaces are often mishandled by shell snippets since +they cause problems for shell pipelines. Not everyone is familiar with +find -print0, xargs -0, git-ls-files -z, etc. Even people who are +familiar with these may assume such flags are not relevant because +someone else renamed any such files in their repo back before the person +doing the filtering joined the project. And often, even those familiar +with handling arguments with spaces may not do so just because they +aren't in the mindset of thinking about everything that could possibly +go wrong. + +* Non-ascii filenames can be silently removed despite being in a desired +directory. Keeping only wanted paths is often done using pipelines like +`git ls-files | grep -v ^WANTED_DIR/ | xargs git rm`. ls-files will +only quote filenames if needed, so folks may not notice that one of the +files didn't match the regex (at least not until it's much too late). +Yes, someone who knows about core.quotePath can avoid this (unless they +have other special characters like \t, \n, or "), and people who use +ls-files -z with something other than grep can avoid this, but that +doesn't mean they will. + +* Similarly, when moving files around, one can find that filenames with +non-ascii or special characters end up in a different directory, one +that includes a double quote character. (This is technically the same +issue as above with quoting, but perhaps an interesting different way +that it can and has manifested as a problem.) + +* It's far too easy to accidentally mix up old and new history. It's +still possible with any tool, but git-filter-branch almost invites it. +If lucky, the only downside is users getting frustrated that they don't +know how to shrink their repo and remove the old stuff. If unlucky, +they merge old and new history and end up with multiple "copies" of each +commit, some of which have unwanted or sensitive files and others which +don't. This comes about in multiple different ways: + + ** the default to only doing a partial history rewrite ('--all' is not + the default and few examples show it) + + ** the fact that there's no automatic post-run cleanup + + ** the fact that --tag-name-filter (when used to rename tags) doesn't + remove the old tags but just adds new ones with the new name + + ** the fact that little educational information is provided to inform + users of the ramifications of a rewrite and how to avoid mixing old + and new history. For example, this man page discusses how users + need to understand that they need to rebase their changes for all + their branches on top of new history (or delete and reclone), but + that's only one of multiple concerns to consider. See the + "DISCUSSION" section of the git filter-repo manual page for more + details. + +* Annotated tags can be accidentally converted to lightweight tags, due +to either of two issues: + + ** Someone can do a history rewrite, realize they messed up, restore + from the backups in refs/original/, and then redo their + git-filter-branch command. (The backup in refs/original/ is not a + real backup; it dereferences tags first.) + + ** Running git-filter-branch with either --tags or --all in your + <rev-list options>. In order to retain annotated tags as + annotated, you must use --tag-name-filter (and must not have + restored from refs/original/ in a previously botched rewrite). + +* Any commit messages that specify an encoding will become corrupted +by the rewrite; git-filter-branch ignores the encoding, takes the original +bytes, and feeds it to commit-tree without telling it the proper +encoding. (This happens whether or not --msg-filter is used.) + +* Commit messages (even if they are all UTF-8) by default become +corrupted due to not being updated -- any references to other commit +hashes in commit messages will now refer to no-longer-extant commits. + +* There are no facilities for helping users find what unwanted crud they +should delete, which means they are much more likely to have incomplete +or partial cleanups that sometimes result in confusion and people +wasting time trying to understand. (For example, folks tend to just +look for big files to delete instead of big directories or extensions, +and once they do so, then sometime later folks using the new repository +who are going through history will notice a build artifact directory +that has some files but not others, or a cache of dependencies +(node_modules or similar) which couldn't have ever been functional since +it's missing some files.) + +* If --prune-empty isn't specified, then the filtering process can +create hoards of confusing empty commits + +* If --prune-empty is specified, then intentionally placed empty +commits from before the filtering operation are also pruned instead of +just pruning commits that became empty due to filtering rules. + +* If --prune empty is specified, sometimes empty commits are missed +and left around anyway (a somewhat rare bug, but it happens...) + +* A minor issue, but users who have a goal to update all names and +emails in a repository may be led to --env-filter which will only update +authors and committers, missing taggers. + +* If the user provides a --tag-name-filter that maps multiple tags to +the same name, no warning or error is provided; git-filter-branch simply +overwrites each tag in some undocumented pre-defined order resulting in +only one tag at the end. (A git-filter-branch regression test requires +this surprising behavior.) + +Also, the poor performance of git-filter-branch often leads to safety +issues: + +* Coming up with the correct shell snippet to do the filtering you want +is sometimes difficult unless you're just doing a trivial modification +such as deleting a couple files. Unfortunately, people often learn if +the snippet is right or wrong by trying it out, but the rightness or +wrongness can vary depending on special circumstances (spaces in +filenames, non-ascii filenames, funny author names or emails, invalid +timezones, presence of grafts or replace objects, etc.), meaning they +may have to wait a long time, hit an error, then restart. The +performance of git-filter-branch is so bad that this cycle is painful, +reducing the time available to carefully re-check (to say nothing about +what it does to the patience of the person doing the rewrite even if +they do technically have more time available). This problem is extra +compounded because errors from broken filters may not be shown for a +long time and/or get lost in a sea of output. Even worse, broken +filters often just result in silent incorrect rewrites. + +* To top it all off, even when users finally find working commands, they +naturally want to share them. But they may be unaware that their repo +didn't have some special cases that someone else's does. So, when +someone else with a different repository runs the same commands, they +get hit by the problems above. Or, the user just runs commands that +really were vetted for special cases, but they run it on a different OS +where it doesn't work, as noted above.
