In Git 2.0, the default will change to the "simple" +semantics, which pushes: + + - only the current branch to the branch with the same name, and only + when the current branch is set to integrate with that remote + branch, if you are pushing to the same remote as you fetch from; or + + - only the current branch to the branch with the same name, if you + are pushing to a remote that is not where you usually fetch from. + +Use the user preference configuration variable "push.default" to +change this. If you are an old-timer who is used to the "matching" +semantics, you can set the variable to "matching" to keep the +traditional behaviour. If you want to live in the future early, you +can set it to "simple" today without waiting for Git 2.0. + +When "git add -u" (and "git add -A") is run inside a subdirectory and +does not specify which paths to add on the command line, it +will operate on the entire tree in Git 2.0 for consistency +with "git commit -a" and other commands. There will be no +mechanism to make plain "git add -u" behave like "git add -u .". +Current users of "git add -u" (without a pathspec) should start +training their fingers to explicitly say "git add -u ." +before Git 2.0 comes. A warning is issued when these commands are +run without a pathspec and when you have local changes outside the +current directory, because the behaviour in Git 2.0 will be different +from today's version in such a situation. + +In Git 2.0, "git add <path>" will behave as "git add -A <path>", so +that "git add dir/" will notice paths you removed from the directory +and record the removal. Versions before Git 2.0, including this +release, will keep ignoring removals, but the users who rely on this +behaviour are encouraged to start using "git add --ignore-removal <path>" +now before 2.0 is released. + +The default prefix for "git svn" will change in Git 2.0. For a long +time, "git svn" created its remote-tracking branches directly under +refs/remotes, but it will place them under refs/remotes/origin/ unless +it is told otherwise with its --prefix option. + + +Updates since v1.8.5 +-------------------- + +Foreign interfaces, subsystems and ports. + + * The HTTP transport, when talking GSS-Negotiate, uses "100 + Continue" response to avoid having to rewind and resend a large + payload, which may not be always doable. + + * Various bugfixes to remote-bzr and remote-hg (in contrib/). + + * The build procedure is aware of MirBSD now. + + +UI, Workflows & Features + + * Just like we give a reasonable default for "less" via the LESS + environment variable, we now specify a reasonable default for "lv" + via the "LV" environment variable when spawning the pager. + + * Two-level configuration variable names in "branch.*" and "remote.*" + hierarchies, whose variables are predominantly three-level, were + not completed by hitting a <TAB> in bash and zsh completions. + + * Fetching 'frotz' branch with "git fetch", while 'frotz/nitfol' + remote-tracking branch from an earlier fetch was still there, would + error out, primarily because the command was not told that it is + allowed to lose any information on our side. "git fetch --prune" + now can be used to remove 'frotz/nitfol' to make room to fetch and + store 'frotz' remote-tracking branch. + + * "diff.orderfile=<file>" configuration variable can be used to + pretend as if the "-O<file>" option were given from the command + line of "git diff", etc. + + * The negative pathspec syntax allows "git log -- . ':!dir'" to tell + us "I am interested in everything but 'dir' directory". + + * "git difftool" shows how many different paths there are in total, + and how many of them have been shown so far, to indicate progress. + + * "git push origin master" used to push our 'master' branch to update + the 'master' branch at the 'origin' repository. This has been + enhanced to use the same ref mapping "git push origin" would use to + determine what ref at the 'origin' to be updated with our 'master'. + For example, with this configuration + + [remote "origin"] + push = refs/heads/*:refs/review/* + + that would cause "git push origin" to push out our local branches + to corresponding refs under refs/review/ hierarchy at 'origin', + "git push origin master" would update 'refs/review/master' over + there. Alternatively, if push.default is set to 'upstream' and our + 'master' is set to integrate with 'topic' from the 'origin' branch, + running "git push origin" while on our 'master' would update their + 'topic' branch, and running "git push origin master" while on any + of our branches does the same. + + * "gitweb" learned to treat ref hierarchies other than refs/heads as + if they are additional branch namespaces (e.g. refs/changes/ in + Gerrit). + + * "git for-each-ref --format=..." learned a few formatting directives; + e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)". + + * The command string given to "git submodule foreach" is passed + directly to the shell, without being eval'ed. This is a backward + incompatible change that may break existing users. + + * "git log" and friends learned the "--exclude=<glob>" option, to + allow people to say "list history of all branches except those that + match this pattern" with "git log --exclude='*/*' --branches". + + * "git rev-parse --parseopt" learned a new "--stuck-long" option to + help scripts parse options with an optional parameter. + + * The "--tags" option to "git fetch" no longer tells the command to + fetch _only_ the tags. It instead fetches tags _in addition to_ + what are fetched by the same command line without the option. + + +Performance, Internal Implementation, etc. + + * When parsing a 40-hex string into the object name, the string is + checked to see if it can be interpreted as a ref so that a warning + can be given for ambiguity. The code kicked in even when the + core.warnambiguousrefs is set to false to squelch this warning, in + which case the cycles spent to look at the ref namespace were an + expensive no-op, as the result was discarded without being used. + + * The naming convention of the packfiles has been updated; it used to + be based on the enumeration of names of the objects that are + contained in the pack, but now it also depends on how the packed + result is represented---packing the same set of objects using + different settings (or delta order) would produce a pack with + different name. + + * "git diff --no-index" mode used to unnecessarily attempt to read + the index when there is one. + + * The deprecated parse-options macro OPT_BOOLEAN has been removed; + use OPT_BOOL or OPT_COUNTUP in new code. + + * A few duplicate implementations of prefix/suffix string comparison + functions have been unified to starts_with() and ends_with(). + + * The new PERLLIB_EXTRA makefile variable can be used to specify + additional directories Perl modules (e.g. the ones necessary to run + git-svn) are installed on the platform when building. + + * "git merge-base" learned the "--fork-point" mode, that implements + the same logic used in "git pull --rebase" to find a suitable fork + point out of the reflog entries for the remote-tracking branch the + work has been based on.

-NAME ----- -git-p4import - Import a Perforce repository into git - - -SYNOPSIS --------- -[verse] -`git-p4import` [-q|-v] [--notags] [--authors <file>] [-t <timezone>] - <//p4repo/path> <branch> -`git-p4import` --stitch <//p4repo/path> -`git-p4import` - - -DESCRIPTION ------------ -Import a Perforce repository into an existing git repository. When -a <//p4repo/path> and <branch> are specified a new branch with the -given name will be created and the initial import will begin. - -Once the initial import is complete you can do an incremental import -of new commits from the Perforce repository. You do this by checking -out the appropriate git branch and then running `git-p4import` without -any options. - -The standard p4 client is used to communicate with the Perforce -repository; it must be configured correctly in order for `git-p4import` -to operate (see below). - - -OPTIONS -------- --q:: - Do not display any progress information. - --v:: - Give extra progress information. - -\--authors:: - Specify an authors file containing a mapping of Perforce user - ids to full names and email addresses (see Notes below). - -\--notags:: - Do not create a tag for each imported commit. - -\--stitch:: - Import the contents of the given perforce branch into the - currently checked out git branch. - -\--log:: - Store debugging information in the specified file. - --t:: - Specify that the remote repository is in the specified timezone. - Timezone must be in the format "US/Pacific" or "Europe/London" - etc. You only need to specify this once, it will be saved in - the git config file for the repository. - -<//p4repo/path>:: - The Perforce path that will be imported into the specified branch. - -<branch>:: - The new branch that will be created to hold the Perforce imports. - - -P4 Client ---------- -You must make the `p4` client command available in your $PATH and -configure it to communicate with the target Perforce repository. -Typically this means you must set the "$P4PORT" and "$P4CLIENT" -environment variables. - -You must also configure a `p4` client "view" which maps the Perforce -branch into the top level of your git repository, for example: - ------------- -Client: myhost - -Root: /home/sean/import - -Options: noallwrite clobber nocompress unlocked modtime rmdir - -View: - //public/jam/... //myhost/jam/... ------------- - -With the above `p4` client setup, you could import the "jam" -perforce branch into a branch named "jammy", like so: - ------------- -$ mkdir -p /home/sean/import/jam -$ cd /home/sean/import/jam -$ git init -$ git p4import //public/jam jammy ------------- - - -Multiple Branches ------------------ -Note that by creating multiple "views" you can use `git-p4import` -to import additional branches into the same git repository. -However, the `p4` client has a limitation in that it silently -ignores all but the last "view" that maps into the same local -directory. So the following will *not* work: - ------------- -View: - //public/jam/... //myhost/jam/... - //public/other/... //myhost/jam/... - //public/guest/... //myhost/jam/... ------------- - -If you want more than one Perforce branch to be imported into the -same directory you must employ a workaround. A simple option is -to adjust your `p4` client before each import to only include a -single view. - -Another option is to create multiple symlinks locally which all -point to the same directory in your git repository and then use -one per "view" instead of listing the actual directory. - - -Tags ----- -A git tag of the form p4/xx is created for every change imported from -the Perforce repository where xx is the Perforce changeset number. -Therefore after the import you can use git to access any commit by its -Perforce number, e.g. git show p4/327. - -The tag associated with the HEAD commit is also how `git-p4import` -determines if there are new changes to incrementally import from the -Perforce repository. - -If you import from a repository with many thousands of changes -you will have an equal number of p4/xxxx git tags. Git tags can -be expensive in terms of disk space and repository operations. -If you don't need to perform further incremental imports, you -may delete the tags. - - -Notes ------ -You can interrupt the import (e.g. ctrl-c) at any time and restart it -without worry. - -Author information is automatically determined by querying the -Perforce "users" table using the id associated with each change. -However, if you want to manually supply these mappings you can do -so with the "--authors" option. It accepts a file containing a list -of mappings with each line containing one mapping in the format: - ------------- - perforce_id = Full Name <email@address.com> ------------- - - -Author ------- -Written by Sean Estabrooks <seanlkml@sympatico.ca> - - -GIT ---- -Part of the gitlink:git[7] suite diff --git a/contrib/remote-helpers/git-remote-bzr b/contrib/remote-helpers/git-remote-bzr index 054161ae21..332aba784b 100755 --- a/contrib/remote-helpers/git-remote-bzr +++ b/contrib/remote-helpers/git-remote-bzr @@ -44,8 +44,8 @@ import StringIO import atexit, shutil, hashlib, urlparse, subprocess NAME_RE = re.compile('^([^<>]+)') -AUTHOR_RE = re.compile('^([^<>]+?)? ?<([^<>]*)>$') -EMAIL_RE = re.compile('^([^<>]+[^ \\\t<>])?\\b(?:[ \\t<>]*?)\\b([^ \\t<>]+@[^ \\t<>]+)') +AUTHOR_RE = re.compile('^([^<>]+?)? ?[<>]([^<>]*)(?:$|>)') +EMAIL_RE = re.compile(r'([^ \t<>]+@[^ \t<>]+)') RAW_AUTHOR_RE = re.compile('^(\w+) (.+)? <(.*)> (\d+) ([+-]\d+)') def die(msg, *args): @@ -193,8 +193,7 @@ def fixup_user(user): else: m = EMAIL_RE.match(user) if m: - name = m.group(1) - mail = m.group(2) + mail = m.group(1) else: m = NAME_RE.match(user) if m: @@ -884,6 +883,16 @@ def main(args): global branches, peers global transports + marks = None + is_tmp = False + gitdir = os.environ.get('GIT_DIR', None) + + if len(args) < 3: + die('Not enough arguments.') + + if not gitdir: + die('GIT_DIR not set') + alias = args[1] url = args[2] @@ -892,7 +901,6 @@ def main(args): blob_marks = {} parsed_refs = {} files_cache = {} - marks = None branches = {} peers = {} transports = [] @@ -900,11 +908,8 @@ def main(args): if alias[5:] == url: is_tmp = True alias = hashlib.sha1(alias).hexdigest() - else: - is_tmp = False prefix = 'refs/bzr/%s' % alias - gitdir = os.environ['GIT_DIR'] dirname = os.path.join(gitdir, 'bzr', alias) if not is_tmp: diff --git a/contrib/remote-helpers/git-remote-hg b/contrib/remote-helpers/git-remote-hg index c6026b9bed..eb89ef6779 100755 --- a/contrib/remote-helpers/git-remote-hg +++ b/contrib/remote-helpers/git-remote-hg @@ -51,8 +51,8 @@ import time as ptime # NAME_RE = re.compile('^([^<>]+)') -AUTHOR_RE = re.compile('^([^<>]+?)? ?<([^<>]*)>$') -EMAIL_RE = re.compile('^([^<>]+[^ \\\t<>])?\\b(?:[ \\t<>]*?)\\b([^ \\t<>]+@[^ \\t<>]+)') +AUTHOR_RE = re.compile('^([^<>]+?)? ?[<>]([^<>]*)(?:$|>)') +EMAIL_RE = re.compile(r'([^ \t<>]+@[^ \t<>]+)') AUTHOR_HG_RE = re.compile('^(.*?) ?<(.*?)(?:>(.+)?)?$') RAW_AUTHOR_RE = re.compile('^(\w+) (?:(.+)? )?<(.*)> (\d+) ([+-]\d+)') @@ -316,8 +316,7 @@ def fixup_user_git(user): else: m = EMAIL_RE.match(user) if m: - name = m.group(1) - mail = m.group(2) + mail = m.group(1) else: m = NAME_RE.match(user) if m: @@ -416,6 +415,9 @@ def get_repo(url, alias): local_path = os.path.join(dirname, 'clone') if not os.path.exists(local_path): hg.share(myui, shared_path, local_path, update=False) + else: + # make sure the shared path is always up-to-date + util.writefile(os.path.join(local_path, '.hg', 'sharedpath'), hg_path) repo = hg.repository(myui, local_path) try: @@ -538,7 +540,7 @@ def export_ref(repo, name, kind, head): print "commit %s" % ref print "mark :%d" % (note_mark) - print "committer remote-hg <> %s" % (ptime.strftime('%s %z')) + print "committer remote-hg <> %d %s" % (ptime.time(), gittz(ptime.timezone)) desc = "Notes for %s\n" % (name) print "data %d" % (len(desc)) print desc @@ -1165,6 +1167,16 @@ def main(args): global dry_run global notes, alias + marks = None + is_tmp = False + gitdir = os.environ.get('GIT_DIR', None) + + if len(args) < 3: + die('Not enough arguments.') + + if not gitdir: + die('GIT_DIR not set') + alias = args[1] url = args[2] peer = None @@ -1185,16 +1197,12 @@ def main(args): if alias[4:] == url: is_tmp = True alias = hashlib.sha1(alias).hexdigest() - else: - is_tmp = False - gitdir = os.environ['GIT_DIR'] dirname = os.path.join(gitdir, 'hg', alias) branches = {} bmarks = {} blob_marks = {} parsed_refs = {} - marks = None parsed_tags = {} filenodes = {} fake_bmark = None diff --git a/contrib/remote-helpers/test-bzr.sh b/contrib/remote-helpers/test-bzr.sh index 5c50251783..1e53ff9a58 100755 --- a/contrib/remote-helpers/test-bzr.sh +++ b/contrib/remote-helpers/test-bzr.sh @@ -5,7 +5,8 @@ test_description='Test remote-bzr' -. ./test-lib.sh +test -n "$TEST_DIRECTORY" || TEST_DIRECTORY=${0%/*}/../../t +.
