Make your code readable and sensible, and don't try to be clever.
As for more concrete guidelines, just imitate the existing code
- We use tabs for indentation.
- - Case arms are indented at the same depth as case and esac lines.
+ - Case arms are indented at the same depth as case and esac lines,
+ like this:
+
+ case "$variable" in
+ pattern1)
+ do this
+ ;;
+ pattern2)
+ do that
+ ;;
+ esac
- Redirection operators should be written with space before, but no
space after them. In other words, write 'echo test >"$file"'
redirection target in a variable (as shown above), our code does so
because some versions of bash issue a warning without the quotes.
+ (incorrect)
+ cat hello > world < universe
+ echo hello >$world
+
+ (correct)
+ cat hello >world <universe
+ echo hello >"$world"
+
- We prefer $( ... ) for command substitution; unlike ``, it
properly nests. It should have been the way Bourne spelled
it from day one, but unfortunately isn't.
"then" should be on the next line for if statements, and "do"
should be on the next line for "while" and "for".
+ (incorrect)
+ if test -f hello; then
+ do this
+ fi
+
+ (correct)
+ if test -f hello
+ then
+ do this
+ fi
+
- We prefer "test" over "[ ... ]".
- We do not write the noiseword "function" in front of shell
functions.
- - We prefer a space between the function name and the parentheses. The
- opening "{" should also be on the same line.
- E.g.: my_function () {
+ - We prefer a space between the function name and the parentheses,
+ and no space inside the parentheses. The opening "{" should also
+ be on the same line.
+
+ (incorrect)
+ my_function(){
+ ...

+ (correct)
+ my_function () {
+ ...
- As to use of grep, stick to a subset of BRE (namely, no \{m,n\},
[::], [==], or [..]) for portability.
interface translatable. See "Marking strings for translation" in
po/README.
+ - We do not write our "test" command with "-a" and "-o" and use "&&"
+ or "||" to concatenate multiple "test" commands instead, because
+ the use of "-a/-o" is often error-prone. E.g.
+
+ test -n "$x" -a "$a" = "$b"
+
+ is buggy and breaks when $x is "=", but
+
+ test -n "$x" && test "$a" = "$b"
+
+ does not have such a problem.
+
+
For C programs:
- We use tabs to indent, and interpret tabs as taking up to
of "else if" statements, it can make sense to add braces to
single line blocks.
- - We try to avoid assignments inside if().
+ - We try to avoid assignments in the condition of an "if" statement.
- Try to make your code understandable. You may put comments
in, but comments invariably tend to stale out when the code
- Double negation is often harder to understand than no negation
at all.
+ - There are two schools of thought when it comes to comparison,
+ especially inside a loop. Some people prefer to have the less stable
+ value on the left hand side and the more stable value on the right hand
+ side, e.g. if you have a loop that counts variable i down to the
+ lower bound,
+
+ while (i > lower_bound) {
+ do something;
+ i--;
+ }
+
+ Other people prefer to have the textual order of values match the
+ actual order of values in their comparison, so that they can
+ mentally draw a number line from left to right and place these
+ values in order, i.e.
+
+ while (lower_bound < i) {
+ do something;
+ i--;
+ }
+
+ Both are valid, and we use both. However, the more "stable" the
+ stable side becomes, the more we tend to prefer the former
+ (comparison with a constant, "i > 0", is an extreme example).
+ Just do not mix styles in the same part of the code and mimic
+ existing styles in the neighbourhood.
+
+ - There are two schools of thought when it comes to splitting a long
+ logical line into multiple lines. Some people push the second and
+ subsequent lines far enough to the right with tabs and align them:
+
+ if (the_beginning_of_a_very_long_expression_that_has_to ||
+ span_more_than_a_single_line_of ||
+ the_source_text) {
+ ...
+
+ while other people prefer to align the second and the subsequent
+ lines with the column immediately inside the opening parenthesis,
+ with tabs and spaces, following our "tabstop is always a multiple
+ of 8" convention:
+
+ if (the_beginning_of_a_very_long_expression_that_has_to ||
+ span_more_than_a_single_line_of ||
+ the_source_text) {
+ ...
+
+ Both are valid, and we use both. Again, just do not mix styles in
+ the same part of the code and mimic existing styles in the
+ neighbourhood.
+
+ - When splitting a long logical line, some people change line before
+ a binary operator, so that the result looks like a parse tree when
+ you turn your head 90-degrees counterclockwise:
+
+ if (the_beginning_of_a_very_long_expression_that_has_to
+ || span_more_than_a_single_line_of_the_source_text) {
+
+ while other people prefer to leave the operator at the end of the
+ line:
+
+ if (the_beginning_of_a_very_long_expression_that_has_to ||
+ span_more_than_a_single_line_of_the_source_text) {
+
+ Both are valid, but we tend to use the latter more, unless the
+ expression gets fairly complex, in which case the former tends to
+ be easier to read. Again, just do not mix styles in the same part
+ of the code and mimic existing styles in the neighbourhood.
+
+ - When splitting a long logical line, with everything else being
+ equal, it is preferable to split after the operator at higher
+ level in the parse tree. That is, this is more preferable:
+
+ if (a_very_long_variable * that_is_used_in +
+ a_very_long_expression) {
+ ...
+
+ than
+
+ if (a_very_long_variable *
+ that_is_used_in + a_very_long_expression) {
+ ...
+
- Some clever tricks, like using the !! operator with arithmetic
constructs, can be extremely confusing to others. Avoid them,
unless there is a compelling reason to use them.

+Git v2.0.1 Release Notes
+========================
+
+ * 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.
+
+ * 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.
+ * 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.
+
+ * "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.
+
+ * 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.
+
+ * The "mailmap.file" configuration option did not support the tilde
+ expansion (i.e. ~user/path and ~/path).
+
+ * 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".
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+ at the beginning of line too aggressively, which is inconsistent
+ with the option of the same name "diff" and "git diff" have.
+
+ * "git blame" miscounted number of columns needed to show localized
+ timestamps, resulting in jaggy left-side-edge of the source code
+ lines in its output.
+
+ * "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.
+
+ * "git commit --allow-empty-message -C $commit" did not work when the
+ commit did not have any log message.
+
+ * "git diff --find-copies-harder" sometimes pretended as if the mode
+ bits have changed for paths that are marked with assume-unchanged
+ bit.
+
+ * "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.
+
+ * "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.
+
+ * "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).
+
+ * 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".
+
+ * The error reporting from "git index-pack" has been improved to
+ distinguish missing objects from type errors.
+
+ * "git mailinfo" used to read beyond the end of header string while
+ parsing an incoming e-mail message to extract the patch.
+
+ * 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.
+
+ * "git pack-objects" unnecessarily copied the previous contents when
+ extending the hashtable, even though it will populate the table
+ from scratch anyway.
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+ was set to a non-default value.
+
+ * "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.
+
+ * "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.
+
+ * 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.
+
+ * "git show -s" (i.e. show log message only) used to incorrectly emit
+ an extra blank line after a merge commit.
+
+ * "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 modify the index while it
+ is running. Detect such a race and avoid overwriting the index.
+
+ * "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 should not to hide
+ changes in the "status" output to cause the users forget to commit
+ them.
+
+ * The mode to run tests with HTTP server tests disabled was broken.

+Git v2.1 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+ * The default value we give to the environment variable LESS has been
+ changed from "FRSX" to "FRX", losing "S" (chop long lines instead
+ of wrapping). 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 the 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 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 propagate the error messages from
+ the webserver better to the client coming over the HTTP transport.
+
+ * The completion script for bash (in contrib/) has been updated to
+ handle aliases that define complex sequence of commands better.
+
+ * The "core.preloadindex" configuration variable is by default
+ enabled, allowing modern platforms to take advantage of the
+ multiple cores they have.
+
+ * "git commit --date=<date>" option learned to read from more
+ timestamp formats, including "--date=now".
+
+ * The `core.commentChar` configuration variable is used to specify a
+ custom comment character other than the default "#" to be used in
+ the commit log editor. This can be set to `auto` to attempt to
+ choose a different character that does not conflict with what
+ already starts a line in the message being edited for cases like
+ "git commit --amend".
+
+ * "git format-patch" learned --signature-file=<file> to take the mail
+ signature from.
+
+ * "git grep" learned grep.fullname configuration variable to force
+ "--full-name" to be default. This may cause regressions on
+ scripted users that 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" set to the
+ "log.decorate" configuration variable to enable the "--decorate"
+ option automatically when the output is sent to tty.
+
+ * "git merge" without 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?". Among the two
+ purposes this prompt serves, ignore the use case to confirm that
+ the user wants to view particular path with the named tool, and
+ redefine the meaning of the prompt only to confirm the choice of
+ the tool made by the autodetection (for those who configured the
+ tool explicitly, the prompt shown for the latter purpose is
+ simply annoying).
+
+ Strictly speaking, this is a backward incompatible change and the
+ users need to explicitly set the variable to 'true' if they want
+ to resurrect the now-ignored use case.
+
+ * "git replace" learned the "--edit" subcommand.
+
+ * "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.
+
+
+Performance, Internal Implementation, etc.
+
+ * Build procedure for 'subtree' (in contrib/) has been cleaned up.
+
+ * 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) have 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.
+
+ * 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.

+track are contained in this release (see the maintenance releases'

When no remote is specified, by default the `origin` remote will be used,
unless there's an upstream branch configured for the current branch.

+CONFIGURED REMOTE-TRACKING BRANCHES[[CRTB]]
+-------------------------------------------
+
+You often interact with the same remote repository by
+regularly and repeatedly fetching from it. In order to keep track
+of the progress of such a remote repository, `git fetch` allows you
+to configure `remote.<repository>.fetch` configuration variables.
+
+Typically such a variable may look like this:
+
+------------------------------------------------
+[remote "origin"]
+ fetch = +refs/heads/*:refs/remotes/origin/*
+------------------------------------------------
+
+This configuration is used in two ways:
+
+* When `git fetch` is run without specifying what branches
+ and/or tags to fetch on the command line, e.g. `git fetch origin`
+ or `git fetch`, `remote.<repository>.fetch` values are used as
+ the refspecs---they specify which refs to fetch and which local refs
+ to update. The example above will fetch
+ all branches that exist in the `origin` (i.e. any ref that matches
+ the left-hand side of the value, `refs/heads/*`) and update the
+ corresponding remote-tracking branches in the `refs/remotes/origin/*`
+ hierarchy.
+
+* When `git fetch` is run with explicit branches and/or tags
+ to fetch on the command line, e.g. `git fetch origin master`, the
+ <refspec>s given on the command line determine what are to be
+ fetched (e.g. `master` in the example,
+ which is a short-hand for `master:`, which in turn means
+ "fetch the 'master' branch but I do not explicitly say what
+ remote-tracking branch to update with it from the command line"),
+ and the example command will
+ fetch _only_ the 'master' branch. The `remote.<repository>.fetch`
+ values determine which
+ remote-tracking branch, if any, is updated. When used in this
+ way, the `remote.<repository>.fetch` values do not have any
+ effect in deciding _what_ gets fetched (i.e. the values are not
+ used as refspecs when the command-line lists refspecs); they are
+ only used to decide _where_ the refs that are fetched are stored
+ by acting as a mapping.
+
+The latter use of the `remote.<repository>.fetch` values can be
+overridden by giving the `--refmap=<refspec>` parameter(s) on the
+command line.
+
+
EXAMPLES
--------
The `pu` branch will be updated even if it is does not fast-forward,
because it is prefixed with a plus sign; `tmp` will not be.
+* Peek at a remote's branch, without configuring the remote in your local
+repository:
++
+------------------------------------------------
+$ git fetch git://git.kernel.org/pub/scm/git/git.git maint
+$ git log FETCH_HEAD
+------------------------------------------------
++
+The first command fetches the `maint` branch from the repository at
+`git://git.kernel.org/pub/scm/git/git.git` and the second command uses
+`FETCH_HEAD` to examine the branch with linkgit:git-log[1]. The fetched
+objects will eventually be removed by git's built-in housekeeping (see
+linkgit:git-gc[1]).

DESCRIPTION
-----------
-A "patch ID" is nothing but a SHA-1 of the diff associated with a patch, with

+A "patch ID" is nothing but a sum of SHA-1 of the file diffs associated with a

+have the same "patch ID" are almost guaranteed to be the same thing.

OPTIONS
-------
+
+--stable::
+ Use a "stable" sum of hashes as the patch ID. With this option:
+ - Reordering file diffs that make up a patch does not affect the ID.
+ In particular, two patches produced by comparing the same two trees
+ with two different settings for "-O<orderfile>" result in the same
+ patch ID signature, thereby allowing the computed result to be used
+ as a key to index some meta-information about the change between
+ the two trees;
+
+ - Result is different from the value produced by git 1.9 and older
+ or produced when an "unstable" hash (see --unstable below) is
+ configured - even when used on a diff output taken without any use
+ of "-O<orderfile>", thereby making existing databases storing such
+ "unstable" or historical patch-ids unusable.
+
+ This is the default if patchid.stable is set to true.
+
+--unstable::
+ Use an "unstable" hash as the patch ID. With this option,
+ the result produced is compatible with the patch-id value produced

+Subject: Beginner question on "Pull is mostly evil"
+Abstract: This how-to explains a method for keeping a
+ project's history correct when using git pull.
+Content-type: text/asciidoc
+
+Keep authoritative canonical history correct with git pull
+==========================================================
+
+Sometimes a new project integrator will end up with project history
+that appears to be "backwards" from what other project developers
+expect. This howto presents a suggested integration workflow for
+maintaining a central repository.
+
+Suppose that that central repository has this history:
+
+------------
+ ---o---o---A
+------------
+
+which ends at commit `A` (time flows from left to right and each node
+in the graph is a commit, lines between them indicating parent-child
+relationship).
+
+Then you clone it and work on your own commits, which leads you to
+have this history in *your* repository:
+
+------------
+ ---o---o---A---B---C
+------------
+
+Imagine your coworker did the same and built on top of `A` in *his*
+repository in the meantime, and then pushed it to the
+central repository:
+
+------------
+ ---o---o---A---X---Y---Z
+------------
+
+Now, if you `git push` at this point, because your history that leads
+to `C` lacks `X`, `Y` and `Z`, it will fail. You need to somehow make
+the tip of your history a descendant of `Z`.
+
+One suggested way to solve the problem is "fetch and then merge", aka
+`git pull`. When you fetch, your repository will have a history like
+this:
+
+------------
+ ---o---o---A---B---C
+ \
+ X---Y---Z
+------------
+
+Once you run merge after that, while still on *your* branch, i.e. `C`,
+you will create a merge `M` and make the history look like this:
+
+------------
+ ---o---o---A---B---C---M
+ \ /
+ X---Y---Z
+------------
+
+`M` is a descendant of `Z`, so you can push to update the central
+repository. Such a merge `M` does not lose any commit in both
+histories, so in that sense it may not be wrong, but when people want
+to talk about "the authoritative canonical history that is shared
+among the project participants", i.e. "the trunk", they often view
+it as "commits you see by following the first-parent chain", and use
+this command to view it:
+
+------------
+ $ git log --first-parent
+------------
+
+For all other people who observed the central repository after your
+coworker pushed `Z` but before you pushed `M`, the commit on the trunk
+used to be `o-o-A-X-Y-Z`. But because you made `M` while you were on
+`C`, `M`'s first parent is `C`, so by pushing `M` to advance the
+central repository, you made `X-Y-Z` a side branch, not on the trunk.
+
+You would rather want to have a history of this shape:
+
+------------
+ ---o---o---A---X---Y---Z---M'
+ \ /
+ B-----------C
+------------
+
+so that in the first-parent chain, it is clear that the project first
+did `X` and then `Y` and then `Z` and merged a change that consists of
+two commits `B` and `C` that achieves a single goal. You may have
+worked on fixing the bug #12345 with these two patches, and the merge
+`M'` with swapped parents can say in its log message "Merge
+fix-bug-12345". Having a way to tell `git pull` to create a merge
+but record the parents in reverse order may be a way to do so.
+
+Note that I said "achieves a single goal" above, because this is
+important. "Swapping the merge order" only covers a special case
+where the project does not care too much about having unrelated
+things done on a single merge but cares a lot about first-parent
+chain.
+
+There are multiple schools of thought about the "trunk" management.
+
+ 1. Some projects want to keep a completely linear history without any
+ merges. Obviously, swapping the merge order would not match their
+ taste. You would need to flatten your history on top of the
+ updated upstream to result in a history of this shape instead:
++
+------------
+ ---o---o---A---X---Y---Z---B---C
+------------
++
+with `git pull --rebase` or something.
+
+ 2. Some projects tolerate merges in their history, but do not worry
+ too much about the first-parent order, and allow fast-forward
+ merges. To them, swapping the merge order does not hurt, but
+ it is unnecessary.
+
+ 3. Some projects want each commit on the "trunk" to do one single
+ thing. The output of `git log --first-parent` in such a project
+ would show either a merge of a side branch that completes a single
+ theme, or a single commit that completes a single theme by itself.
+ If your two commits `B` and `C` (or they may even be two groups of
+ commits) were solving two independent issues, then the merge `M'`
+ we made in the earlier example by swapping the merge order is
+ still not up to the project standard. It merges two unrelated
+ efforts `B` and `C` at the same time.
+
+For projects in the last category (Git itself is one of them),
+individual developers would want to prepare a history more like
+this:
+
+------------
+ C0--C1--C2 topic-c
+ /
+ ---o---o---A master
+ \
+ B0--B1--B2 topic-b
+------------
+
+That is, keeping separate topics on separate branches, perhaps like
+so:
+
+------------
+ $ git clone $URL work && cd work
+ $ git checkout -b topic-b master
+ $ ... work to create B0, B1 and B2 to complete one theme
+ $ git checkout -b topic-c master
+ $ ... same for the theme of topic-c
+------------
+
+And then
+
+------------
+ $ git checkout master
+ $ git pull --ff-only
+------------
+
+would grab `X`, `Y` and `Z` from the upstream and advance your master
+branch:
+
+------------
+ C0--C1--C2 topic-c
+ /
+ ---o---o---A---X---Y---Z master
+ \
+ B0--B1--B2 topic-b
+------------
+
+And then you would merge these two branches separately:
+
+------------
+ $ git merge topic-b
+ $ git merge topic-c
+------------
+
+to result in
+
+------------
+ C0--C1---------C2
+ / \
+ ---o---o---A---X---Y---Z---M---N
+ \ /
+ B0--B1-----B2
+------------
+
+and push it back to the central repository.
+
+It is very much possible that while you are merging topic-b and
+topic-c, somebody again advanced the history in the central repository
+to put `W` on top of `Z`, and make your `git push` fail.
+
+In such a case, you would rewind to discard `M` and `N`, update the
+tip of your 'master' again and redo the two merges:
+
+------------
+ $ git reset --hard origin/master
+ $ git pull --ff-only
+ $ git merge topic-b
+ $ git merge topic-c
+------------
+
+The procedure will result in a history that looks like this:
+
+------------
+ C0--C1--------------C2
+ / \
+ ---o---o---A---X---Y---Z---W---M'--N'
+ \ /
+ B0--B1---------B2
+------------

-The git-diffall script provides a directory based diff mechanism
-for git.
-
-To determine what diff viewer is used, the script requires either
-the 'diff.tool' or 'merge.tool' configuration option to be set.
-
-This script is compatible with most common forms used to specify a
-range of revisions to diff:
-
- 1. git diffall: shows diff between working tree and staged changes
- 2. git diffall --cached [<commit>]: shows diff between staged
- changes and HEAD (or other named commit)
- 3. git diffall <commit>: shows diff between working tree and named
- commit
- 4. git diffall <commit> <commit>: show diff between two named commits
- 5. git diffall <commit>..<commit>: same as above
- 6. git diffall <commit>...<commit>: show the changes on the branch
- containing and up to the second, starting at a common ancestor
- of both <commit>
-
-Note: all forms take an optional path limiter [-- <path>*]
-
-The '--extcmd=<command>' option allows the user to specify a custom
-command for viewing diffs. When given, configured defaults are
-ignored and the script runs $command $LOCAL $REMOTE. Additionally,
-$BASE is set in the environment.
-
-This script is based on an example provided by Thomas Rast on the
-Git list [1]:
-
-[1] http://thread.gmane.org/gmane.comp.version-control.git/124807

-#!/bin/sh
-# Copyright 2010 - 2012, Tim Henigan <tim.henigan@gmail.com>
-#
-# Perform a directory diff between commits in the repository using
-# the external diff or merge tool specified in the user's config.
-
-USAGE='[--cached] [--copy-back] [-x|--extcmd=<command>] <commit>{0,2} [-- <path>*]
-
- --cached Compare to the index rather than the working tree.
-
- --copy-back Copy files back to the working tree when the diff
- tool exits (in case they were modified by the
- user). This option is only valid if the diff
- compared with the working tree.
-
- -x=<command>
- --extcmd=<command> Specify a custom command for viewing diffs.
- git-diffall ignores the configured defaults and
- runs $command $LOCAL $REMOTE when this option is
- specified. Additionally, $BASE is set in the
- environment.

-Syntax highlighting for git commit messages, config files, etc. is
-included with the vim distribution as of vim 7.2, and should work
-automatically.
-
-If you have an older version of vim, you can get the latest syntax
-files from the vim project:
-
- http://ftp.vim.org/pub/vim/runtime/syntax/git.vim
- http://ftp.vim.org/pub/vim/runtime/syntax/gitcommit.vim
- http://ftp.vim.org/pub/vim/runtime/syntax/gitconfig.vim
- http://ftp.vim.org/pub/vim/runtime/syntax/gitrebase.vim
- http://ftp.vim.org/pub/vim/runtime/syntax/gitsendemail.vim
-
-These files are also available via FTP at the same location.
-
-To install:
-
- 1. Copy these files to vim's syntax directory $HOME/.vim/syntax
- 2. To auto-detect the editing of various git-related filetypes:
-
- $ curl http://ftp.vim.org/pub/vim/runtime/filetype.vim |
- sed -ne '/^" Git$/, /^$/ p' >>$HOME/.vim/filetype.vim

numbers matching <pattern>. The number matched against is
simply the running count of the test within the file.

This may help the person who is developing a new test.
It causes the command defined with test_debug to run.
failed tests so that you can inspect its contents after
the test finished.
+-i::
--immediate::
This causes the test to immediately exit upon the first
failed test. Cleanup commands requested with
in order to keep the state for inspection by the tester
to diagnose the bug.
+-l::
--long-tests::
This causes additional long-running tests to be run (where
available), for more exhaustive testing.
+-r::
+--run=<test-selector>::
+ Run only the subset of tests indicated by
+ <test-selector>. See section "Skipping Tests" below for
+ <test-selector> syntax.
+
--valgrind=<tool>::
Execute all Git binaries under valgrind tool <tool> and exit
with status 126 on errors (just like regular tests, this will
test, or t[0-9]{4} followed by ".$number" to say which
particular test to skip.
-Note that some tests in the existing test suite rely on previous
-test item, so you cannot arbitrarily disable one and expect the
-remainder of test to check what the test originally was intended
-to check.
+For an individual test suite --run could be used to specify that
+only some tests should be run or that some tests should be
+excluded from a run.
+
+The argument for --run is a list of individual test numbers or
+ranges with an optional negation prefix that define what tests in
+a test suite to include in the run. A range is two numbers
+separated with a dash and matches a range of tests with both ends
+been included. You may omit the first or the second number to
+mean "from the first test" or "up to the very last test"
+respectively.
+
+Optional prefix of '!' means that the test or a range of tests
+should be excluded from the run.
+
+If --run starts with an unprefixed number or range the initial
+set of tests to run is empty. If the first item starts with '!'
+all the tests are added to the initial set. After initial set is
+determined every test number or range is added or excluded from
+the set one by one, from left to right.
+
+Individual numbers or ranges could be separated either by a space
+or a comma.
+
+For example, to run only tests up to a specific test (21), one
+could do this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1-21'
+
+or this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='-21'
+
+Common case is to run several setup tests (1, 2, 3) and then a
+specific test (21) that relies on that setup:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1 2 3 21'
+
+or:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run=1,2,3,21
+
+or:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='-3 21'
+
+As noted above, the test set is built going though items left to
+right, so this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='1-4 !3'
+
+will run tests 1, 2, and 4. Items that comes later have higher
+precendence. It means that this:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='!3 1-4'
+
+would just run tests from 1 to 4, including 3.
+
+You may use negation with ranges. The following will run all
+test in the test suite except from 7 up to 11:
+
+ $ sh ./t9200-git-cvsexport-commit.sh --run='!7-11'
+
+Some tests in a test suite rely on the previous tests performing
+certain actions, specifically some tests are designated as
+"setup" test, so you cannot _arbitrarily_ disable one test and
+expect the rest to function correctly.
+
+--run is mostly useful when you want to focus on a specific test
+and know what setup is needed for it. Or when you want to run
+everything up to a certain test.
Naming Tests

+ * 2) t > p[imin];
+ * 3) t = p[imin].
+ *
+ * Schematic deduction of what every case means, and what to do, follows:
+ *
+ * 1) t < p[imin] -> ∀j t ∉ Pj -> "+t" ∈ D(T,Pj) -> D += "+t"; t↓
+ *
+ * 2) t > p[imin]

+ *
+ * 3) t = p[imin]
+ *
+ * 3.1) ∃j: pj > p[imin] -> "+t" ∈ D(T,Pj) -> only pi=p[imin] remains to investigate
