Existing users who prefer not to see line-wrapped - output may want to set - - $ git config core.pager "less -S" - - to restore the traditional behaviour. It is expected that people - find output from most subcommands easier to read with the new - default, except for "blame" which tends to produce really long - lines. To override the new default only for "git blame", you can - do this: - - $ git config pager.blame "less -S" - - * A few disused directories in contrib/ have been retired. - - -Updates since v2.0 ------------------- - -UI, Workflows & Features - - * Since the very beginning of Git, we gave the LESS environment a - default value "FRSX" when we spawn "less" as the pager. "S" (chop - long lines instead of wrapping) has been removed from this default - set of options, because it is more or less a personal taste thing, - as opposed to the others that have good justifications (i.e. "R" is - very much justified because many kinds of output we produce are - colored and "FX" is justified because output we produce is often - shorter than a page). - - * The logic and data used to compute the display width needed for - UTF-8 strings have been updated to match Unicode 7.0 better. - - * HTTP-based transports learned to better propagate the error messages from - the webserver to the client coming over the HTTP transport. - - * The completion script for bash (in contrib/) has been updated to - better handle aliases that define a complex sequence of commands. - - * The "core.preloadindex" configuration variable is enabled by default, - allowing modern platforms to take advantage of their - multiple cores. - - * "git clone" applies the "if cloning from a local disk, physically - copy the repository using hardlinks, unless otherwise told not to with - --no-local" optimization when the url.*.insteadOf mechanism rewrites a - remote-repository "git clone $URL" into a - clone from a local disk. - - * "git commit --date=<date>" option learned more - timestamp formats, including "--date=now". - - * The `core.commentChar` configuration variable is used to specify a - custom comment character (other than the default "#") for - the commit message editor. This can be set to `auto` to attempt to - choose a different character that does not conflict with any that - already starts a line in the message being edited, for cases like - "git commit --amend". - - * "git format-patch" learned --signature-file=<file> to add the contents - of a file as a signature to the mail message it produces. - - * "git grep" learned the grep.fullname configuration variable to force - "--full-name" to be the default. This may cause regressions for - scripted users who do not expect this new behaviour. - - * "git imap-send" learned to ask the credential helper for auth - material. - - * "git log" and friends now understand the value "auto" for the - "log.decorate" configuration variable to enable the "--decorate" - option automatically when the output is sent to tty. - - * "git merge" without an argument, even when there is an upstream - defined for the current branch, refused to run until - merge.defaultToUpstream is set to true. Flip the default of that - configuration variable to true. - - * "git mergetool" learned to drive the vimdiff3 backend. - - * mergetool.prompt used to default to 'true', always asking "do you - really want to run the tool on this path?". The default has been - changed to 'false'. However, the prompt will still appear if - mergetool used its autodetection system to guess which tool to use. - Users who explicitly specify or configure a tool will no longer see - the prompt by default. - - Strictly speaking, this is a backward incompatible change and - users need to explicitly set the variable to 'true' if they want - to be prompted to confirm running the tool on each path. - - * "git replace" learned the "--edit" subcommand to create a - replacement by editing an existing object. - - * "git replace" learned a "--graft" option to rewrite the parents of a - commit. - - * "git send-email" learned "--to-cover" and "--cc-cover" options, to - tell it to copy To: and Cc: headers found in the first input file - when emitting later input files. - - * "git svn" learned to cope with malformed timestamps with only one - digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted - by some broken subversion server implementations. - - * "git tag" when editing the tag message shows the name of the tag - being edited as a comment in the editor. - - * "git tag" learned to pay attention to "tag.sort" configuration, to - be used as the default sort order when no --sort=<value> option - is given. - - * A new "git verify-commit" command, to check GPG signatures in signed - commits, in a way similar to "git verify-tag" is used to check - signed tags, was added. - - -Performance, Internal Implementation, etc. - - * Build procedure for 'subtree' (in contrib/) has been cleaned up. - - * Support for the profile-feedback build, which has - bit-rotted for quite a while, has been updated. - - * An experimental format to use two files (the base file and - incremental changes relative to it) to represent the index has been - introduced; this may reduce I/O cost of rewriting a large index - when only small part of the working tree changes. - - * Effort to shrink the size of patches Windows folks maintain on top - by upstreaming them continues. More tests that are not applicable - to the Windows environment are identified and either skipped or - made more portable. - - * Eradication of "test $condition -a $condition" from our scripts - continues. - - * The `core.deltabasecachelimit` used to default to 16 MiB , but this - proved to be too small, and has been bumped to 96 MiB. - - * "git blame" has been optimized greatly by reorganising the data - structure that is used to keep track of the work to be done. - - * "git diff" that compares 3-or-more trees (e.g. parents and the - result of a merge) has been optimized. - - * The API to update/delete references are being converted to handle - updates to multiple references in a transactional way. As an - example, "update-ref --stdin [-z]" has been updated to use this - API. - - * skip_prefix() and strip_suffix() API functions are used a lot more - widely throughout the codebase now. - - * Parts of the test scripts can be skipped by using a range notation, - e.g. "sh t1234-test.sh --run='1-4 6 8-'" to omit test piece 5 and 7 - and run everything else. - - -Also contains various documentation updates and code clean-ups. - - -Fixes since v2.0 ----------------- - -Unless otherwise noted, all the fixes since v2.0 in the maintenance -track are contained in this release (see the maintenance releases' -notes for details). - - * We used to unconditionally disable the pager in the pager process - we spawn to feed out output, but that prevented people who want to - run "less" within "less" from doing so. - (merge c0459ca je/pager-do-not-recurse later to maint). - - * Tools that read diagnostic output in our standard error stream do - not want to see terminal control sequence (e.g. erase-to-eol). - Detect them by checking if the standard error stream is connected - to a tty. - (merge 38de156 mn/sideband-no-ansi later to maint). - - * Mishandling of patterns in .gitignore that have trailing SPs quoted - with backslashes (e.g. ones that end with "\ ") has been - corrected. - (merge 97c1364be6b pb/trim-trailing-spaces later to maint). - - * Reworded the error message given upon a failure to open an existing - loose object file due to e.g. permission issues; it was reported as - the object being corrupt, but that is not quite true. - (merge d6c8a05 jk/report-fail-to-read-objects-better later to maint). - - * "git log -2master" is a common typo that shows two commits starting - from whichever random branch that is not 'master' that happens to - be checked out currently. - (merge e3fa568 jc/revision-dash-count-parsing later to maint). - - * Code to avoid adding the same alternate object store twice was - subtly broken for a long time, but nobody seems to have noticed. - (merge 80b4785 rs/fix-alt-odb-path-comparison later to maint). - (merge 539e750 ek/alt-odb-entry-fix later to maint). - - * The "%<(10,trunc)%s" pretty format specifier in the log family of - commands is used to truncate the string to a given length (e.g. 10 - in the example) with padding to column-align the output, but did - not take into account that number of bytes and number of display - columns are different. - (merge 7d50987 as/pretty-truncate later to maint). - - * "%G" (nothing after G) is an invalid pretty format specifier, but - the parser did not notice it as garbage. - (merge 958b2eb jk/pretty-G-format-fixes later to maint). - - * A handful of code paths had to read the commit object more than - once when showing header fields that are usually not parsed. The - internal data structure to keep track of the contents of the commit - object has been updated to reduce the need for this double-reading, - and to allow the caller find the length of the object. - (merge 218aa3a jk/commit-buffer-length later to maint). - - * The "mailmap.file" configuration option did not support tilde - expansion (i.e. ~user/path and ~/path). - (merge 9352fd5 ow/config-mailmap-pathname later to maint). - - * The completion scripts (in contrib/) did not know about quite a few - options that are common between "git merge" and "git pull", and a - couple of options unique to "git merge". - (merge 8fee872 jk/complete-merge-pull later to maint). - - * The unix-domain socket used by the sample credential cache daemon - tried to unlink an existing stale one at a wrong path, if the path - to the socket was given as an overlong path that does not fit in - the sun_path member of the sockaddr_un structure. - (merge 2869b3e rs/fix-unlink-unix-socket later to maint). - - * An ancient rewrite passed a wrong pointer to a curl library - function in a rarely used code path. - (merge 479eaa8 ah/fix-http-push later to maint). - - * "--ignore-space-change" option of "git apply" ignored the spaces - at the beginning of lines too aggressively, which is inconsistent - with the option of the same name that "diff" and "git diff" have. - (merge 14d3bb4 jc/apply-ignore-whitespace later to maint). - - * "git blame" miscounted the number of columns needed to show localized - timestamps, resulting in a jaggy left-side-edge for the source code - lines in its output. - (merge dd75553 jx/blame-align-relative-time later to maint). - - * "git blame" assigned the blame to the copy in the working-tree if - the repository is set to core.autocrlf=input and the file used CRLF - line endings. - (merge 4d4813a bc/blame-crlf-test later to maint). - - * "git clone -b brefs/tags/bar" would have mistakenly thought we were - following a single tag, even though it was a name of the branch, - because it incorrectly used strstr(). - (merge 60a5f5f jc/fix-clone-single-starting-at-a-tag later to maint). - - * "git commit --allow-empty-message -C $commit" did not work when the - commit did not have any log message. - (merge 076cbd6 jk/commit-C-pick-empty later to maint). - - * "git diff --find-copies-harder" sometimes pretended as if the mode - bits have changed for paths that are marked with the assume-unchanged - bit. - (merge 5304810 jk/diff-files-assume-unchanged later to maint). - - * "filter-branch" left an empty single-parent commit that results when - all parents of a merge commit get mapped to the same commit, even - under "--prune-empty". - (merge 79bc4ef cb/filter-branch-prune-empty-degenerate-merges later to maint). - - * "git format-patch" did not enforce the rule that the "--follow" - option from the log/diff family of commands must be used with - exactly one pathspec. - (merge dd63f16 jk/diff-follow-must-take-one-pathspec later to maint). - - * "git gc --auto" was recently changed to run in the background to - give control back early to the end-user sitting in front of the - terminal, but it forgot that housekeeping involving reflogs should - be done without other processes competing for accesses to the refs. - (merge 62aad18 nd/daemonize-gc later to maint). - - * "git grep -O" to show the lines that hit in the pager did not work - well with case insensitive search. We now spawn "less" with its - "-I" option when it is used as the pager (which is the default). - (merge f7febbe sk/spawn-less-case-insensitively-from-grep-O-i later to maint). - - * We used to disable threaded "git index-pack" on platforms without - thread-safe pread(); use a different workaround for such - platforms to allow threaded "git index-pack". - (merge 3953949 nd/index-pack-one-fd-per-thread later to maint). - - * The error reporting from "git index-pack" has been improved to - distinguish missing objects from type errors. - (merge 77583e7 jk/index-pack-report-missing later to maint). - - * "log --show-signature" incorrectly decided the color to paint a - mergetag that was and was not correctly validated. - (merge 42c55ce mg/fix-log-mergetag-color later to maint). - - * "log --show-signature" did not pay attention to the "--graph" option. - (merge cf3983d zk/log-graph-showsig later to maint). - - * "git mailinfo" used to read beyond the ends of header strings while - parsing an incoming e-mail message to extract the patch. - (merge b1a013d rs/mailinfo-header-cmp later to maint). - - * On a case insensitive filesystem, merge-recursive incorrectly - deleted the file that is to be renamed to a name that is the same - except for case differences. - (merge baa37bf dt/merge-recursive-case-insensitive later to maint). - - * Merging changes into a file that ends in an incomplete line made the - last line into a complete one, even when the other branch did not - change anything around the end of file. - (merge ba31180 mk/merge-incomplete-files later to maint). - - * "git pack-objects" unnecessarily copied the previous contents when - extending the hashtable, even though it will populate the table - from scratch anyway. - (merge fb79947 rs/pack-objects-no-unnecessary-realloc later to maint). - - * Recent updates to "git repack" started to duplicate objects that - are in packfiles marked with the .keep flag into the new packfile by - mistake. - (merge d078d85 jk/repack-pack-keep-objects later to maint). - - * "git rerere forget" did not work well when merge.conflictstyle - was set to a non-default value. - (merge de3d8bb fc/rerere-conflict-style later to maint). - - * "git remote rm" and "git remote prune" can involve removing many - refs at once, which is not a very efficient thing to do when very - many refs exist in the packed-refs file. - (merge e6bea66 jl/remote-rm-prune later to maint). - - * "git log --exclude=<glob> --all | git shortlog" worked as expected, - but "git shortlog --exclude=<glob> --all", which is supposed to be - identical to the above pipeline, was not accepted at the command - line argument parser level. - (merge eb07774 jc/shortlog-ref-exclude later to maint). - - * The autostash mode of "git rebase -i" did not restore the dirty - working tree state if the user aborted the interactive rebase by - emptying the insn sheet. - (merge ddb5432 rr/rebase-autostash-fix later to maint). - - * "git rebase --fork-point" did not filter out patch-identical - commits correctly. - - * During "git rebase --merge", a conflicted patch could not be - skipped with "--skip" if the next one also conflicted. - (merge 95104c7 bc/fix-rebase-merge-skip later to maint). - - * "git show -s" (i.e. show log message only) used to incorrectly emit - an extra blank line after a merge commit. - (merge ad2f725 mk/show-s-no-extra-blank-line-for-merges later to maint). - - * "git status", even though it is a read-only operation, tries to - update the index with refreshed lstat(2) info to optimize future - accesses to the working tree opportunistically, but this could - race with a "read-write" operation that modifies the index while it - is running. Detect such a race and avoid overwriting the index. - (merge 426ddee ym/fix-opportunistic-index-update-race later to maint). - - * "git status" (and "git commit") behaved as if changes in a modified - submodule are not there if submodule.*.ignore configuration is set, - which was misleading. The configuration is only to unclutter diff - output during the course of development, and not to hide - changes in the "status" output to cause the users forget to commit - them. - (merge c215d3d jl/status-added-submodule-is-never-ignored later to maint). - - * Documentation for "git submodule sync" forgot to say that the subcommand - can take the "--recursive" option. - (merge 9393ae7 mc/doc-submodule-sync-recurse later to maint). - - * "git update-index --cacheinfo" in 2.0 release crashed on a - malformed command line. - (merge c8e1ee4 jc/rev-parse-argh-dashed-multi-words later to maint). - - * The mode to run tests with HTTP server tests disabled was broken. - (merge afa53fe na/no-http-test-in-the-middle later to maint). |
