2010-03-12notes: implement helpers needed for note copying during rewriteLibravatar Thomas Rast1-0/+2
Implement helper functions to load the rewriting config, and to actually copy the notes. Also document the config. Secondly, also implement an undocumented --for-rewrite=<cmd> option to 'git notes copy' which is used like --stdin, but also puts the configuration for <cmd> into effect. It will be needed to support the copying in git-rebase.

2010-03-12Support showing notes from more than one notes treeLibravatar Thomas Rast1-0/+1
With this patch, you can set notes.displayRef to a glob that points at your favourite notes refs, e.g., [notes] displayRef = refs/notes/* Then git-log and friends will show notes from all trees.

append_cr(), remove_cr(), q_to_nul() and q_to_cr() are defined in multiple tests. Consolidate them into test-lib.sh so we can stop redefining them. The use of remove_cr() in t0020 to test for a CR is replaced with a new function has_cr() to accurately reflect what is intended (the output of remove_cr() was being thrown away).

Without this, test-lib checks that the git_remote_helpers directory has been built. However, if we are building without python, we will not have done anything at all in that directory, and test-lib's sanity check will fail. We bump the inclusion of GIT-BUILD-OPTIONS further up in test-lib; it contains configuration, and as such should be read before we do any checks (and in this particular case, we need its value to do our check properly).

2009-11-24Add Python support library for remote helpersLibravatar Sverre Rabbelier1-0/+9
This patch introduces parts of a Python package called "git_remote_helpers" containing the building blocks for remote helpers written in Python. No actual remote helpers are part of this patch, this patch only includes the common basics needed to start writing such helpers. The patch includes the necessary Makefile additions to build and install the git_remote_helpers Python package along with the rest of Git. This patch is based on Johan Herland's git_remote_cvs patch and has been improved by the following contributions: - David Aguilar: Lots of Python coding style fixes - David Aguilar: DESTDIR support in Makefile Cc: David Aguilar <davvid@gmail.com> Cc: Johan Herland <johan@herland.net> Signed-off-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-11-13Do not use VISUAL editor on dumb terminalsLibravatar Jonathan Nieder1-4/+4
Refuse to use $VISUAL and fall back to $EDITOR if TERM is unset or set to "dumb". Traditionally, VISUAL is set to a screen editor and EDITOR to a line-based editor, which should be more useful in that situation. vim, for example, is happy to assume a terminal supports ANSI sequences even if TERM is dumb (e.g., when running from a text editor like Acme). git already refuses to fall back to vi on a dumb terminal if GIT_EDITOR, core.editor, VISUAL, and EDITOR are unset, but without this patch, that check is suppressed by VISUAL=vi.

2009-08-28t/test-lib.sh: provide a shell implementation of the 'yes' utilityLibravatar Brandon Casey1-0/+15
Some platforms (IRIX 6.5, Solaris 7) do not provide the 'yes' utility. Currently, some tests, including t7610 and t9001, try to call this program. Due to the way the tests are structured, the tests still pass even though this program is missing. Rather than succeeding by chance, let's provide an implementation of the simple 'yes' utility in shell for all platforms to use.

2009-08-09tests: allow user to specify trash directory locationLibravatar Jeff King1-1/+8
The tests generate a large amount of I/O activity creating and destroying repositories and files. We can improve the time it takes to run the test suite by creating trash directories on filesystems with better performance characteristic, even though we may not want the rest of the git repository on those filesystems (e.g., because they are not network connected, or because they are temporary ramdisks). For example, on a dual processor system: $ cd t && time make -j32 real 1m51.562s user 0m59.260s sys 1m20.933s # /dev/shm is tmpfs $ cd t && time make -j32 GIT_TEST_OPTS="--root=/dev/shm" real 1m1.484s user 0m53.555s sys 1m5.264s We almost halve the wall clock time, and we utilize the dual processors much better.

2009-08-09tests: provide $TRASH_DIRECTORY variableLibravatar Jeff King1-1/+2
Most scripts don't care about the absolute path to the trash directory. The one exception was t4014 script, which pieced together $TEST_DIRECTORY and $test itself to get an absolute directory. Instead, let's provide a $TRASH_DIRECTORY which specifies the same thing. This keeps the $test variable internal to test-lib.sh and paves the way for trash directories in other locations.

2009-04-21test-lib.sh: Help test_create_repo() find the templates dirLibravatar Michael J Gruber1-1/+1
Currently, test_create_repo() expects that templates can be found below `pwd`/.. This assumption fails when tests are run against a git installed somewhere else or test_create_repo() is called from subdirectiories (several tests do this). Therefore, use $TEST_DIRECTORY as introduced in 2d84e9fb and expect templates to be present in $TEST_DIRECTORY/.. which should be the root dir of the git checkout.

2009-03-25t7502-commit: Skip SIGTERM test on WindowsLibravatar Johannes Sixt1-0/+2
The implementation of exec on Windows is just a rough approximation of the POSIX behavior. In particular, no real process "overlay" happens (a new process is spawned instead and the parent process waits until the child terminates). In particular, the process ID cannot be taken by the exec'd process. But there is one test in t7502-commit.sh that depends on this. We have to skip it on Windows.

2009-03-22Use prerequisite tags to skip tests that depend on symbolic linksLibravatar Johannes Sixt1-0/+4
Many tests depend on that symbolic links work. This introduces a check that sets the prerequisite tag SYMLINKS if the file system supports symbolic links. Since so many tests have to check for this prerequisite, we do the check in test-lib.sh, so that we don't need to repeat the test in many scripts. To check for 'ln -s' failures, you can use a FAT partition on Linux: $ mkdosfs -C git-on-fat 1000000 $ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt Clone git to /mnt and $ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7 t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \ make test (These additionally skipped tests depend on POSIX permissions that FAT on Linux does not provide.)

2009-03-21test-lib: Infrastructure to test and check for prerequisitesLibravatar Johannes Sixt1-5/+39
Some tests can be run only if a particular prerequisite is available. For example, some tests require that an UTF-8 locale is available. Here we introduce functions that are used in this way: 1. Insert code that checks whether the prerequisite is available. If it is, call test_set_prereq with an arbitrary tag name that subsequently can be used to check for the prerequisite: case $LANG in *.utf-8) test_set_prereq UTF8 ;; esac 2. In the calls to test_expect_success pass the tag name: test_expect_success UTF8 '...description...' '...tests...' 3. There is an auxiliary predicate that can be used anywhere to test for a prerequisite explicitly: if test_have_prereq UTF8 then ...code to be skipped if prerequisite is not available... fi Signed-off-by: Johannes Sixt <j6t@kdbg.org>
2009-03-19Tests on Windows: $(pwd) must return Windows-style pathsLibravatar Johannes Sixt1-0/+4
Many tests pass $(pwd) in some form to git and later test that the output of git contains the correct value of $(pwd). For example, the test of 'git remote show' sets up a remote that contains $(pwd) and then the expected result must contain $(pwd). Again, MSYS-bash's path mangling kicks in: Plain $(pwd) uses the MSYS style absolute path /c/path/to/git. The test case would write this name into the 'expect' file. But when git is invoked, MSYS-bash converts this name to the Windows style path c:/path/to/git, and git would produce this form in the result; the test would fail. We fix this by passing -W to bash's pwd that produces the Windows-style path. There are a two cases that need an accompanying change: - In t1504 the value of $(pwd) becomes part of a path list. In this case, the lone 'c' in something like /foo:c:/path/to/git:/bar inhibits MSYS-bashes path mangling; IOW in this case we want the /c/path/to/git form to allow path mangling. We use $PWD instead of $(pwd), which always has the latter form. - In t6200, $(pwd) - the Windows style path - must be used to construct the expected result because that is the path form that git sees. (The change in the test itself is just for consistency: 'git fetch' always sees the Windows-style path, with or without the change.) Signed-off-by: Johannes Sixt <j6t@kdbg.org>

2009-03-19test-lib: Work around incompatible sort and find on WindowsLibravatar Johannes Sixt1-0/+13

2009-03-19test-lib: Introduce test_chmod and use it instead of update-index --chmodLibravatar Johannes Sixt1-0/+9
This function replaces sequences of 'chmod +x' and 'git update-index --chmod=+x' in the test suite, whose purpose is to help filesystems that need core.filemode=false. Two places where only 'chmod +x' was used we also use this new function. The function calls 'git update-index --chmod' without checking core.filemode (unlike some of the call sites did). We do this because the call sites *expect* that the executable bit ends up in the index (ie. it is not the purpose of the call sites to *test* whether git treats 'chmod +x' and 'update-index --chmod=+x' correctly). Therefore, on filesystems with core.filemode=true the 'git update-index --chmod' is a no-op. The function uses --add with update-index to help one call site in t6031-merge-recursive. It makes no difference for the other callers. Signed-off-by: Johannes Sixt <j6t@kdbg.org>

Introduce variables GIT_TEST_INSTALLED and GIT_TEST_EXEC_PATH such that the test suite can be run against a git which is installed at GIT_TEST_INSTALLED with subcommands at GIT_TEST_EXEC_PATH. GIT_TEST_INSTALLED defaults to the git.git checkout, GIT_TEST_EXEC_PATH defaults to the output of '$GIT_TEST_INSTALLED/git --exec-path'.

2009-02-03test-lib.sh: optionally output to test-results/$TEST.out, tooLibravatar Johannes Schindelin1-0/+18
When tests are run in parallel and a few tests fail, it does not help that the output of the terminal is totally confusing, as you rarely know which test which line came from. So introduce the option '--tee' which triggers that the output of the tests will be written to t/test-results/$TEST.out in addition to the terminal, where $TEST is the basename of the script. Unfortunately, there seems to be no way to redirect a given file descriptor to a specified subprocess in POSIX shell, only redirection to a file is supported via 'exec > $FILE'. At least with bash, one might think that 'exec >($COMMAND)' would work as intended, but it does not. The common way to work around the lack of proper tools support is to work with named pipes, alas, one of our most beloved platforms does not really support named pipes. Besides, we would need a pipe for every script, as the whole point of this patch is to allow parallel execution. Therefore, we handle the redirection in the following way: when '--tee' was passed to the test script, the variable GIT_TEST_TEE_STARTED is set (to avoid triggering that code path again) and the script is started _again_, in a subshell, redirected to the command "tee".
