2014-06-09test: turn EXPENSIVE into a lazy prerequisiteLibravatar Junio C Hamano1-2/+0
Two test scripts (t0021 and t5551) had copy & paste code to set EXPENSIVE prerequisite. Use the test_lazy_prereq helper to define them in the common t/test-lib.sh. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-08-20xread, xwrite: limit size of IO to 8MBLibravatar Steffen Prohaska1-0/+14
Checking out 2GB or more through an external filter (see test) fails on Mac OS X 10.8.4 (12E55) for a 64-bit executable with: error: read from external filter cat failed error: cannot feed the input to external filter cat error: cat died of signal 13 error: external filter cat failed 141 error: external filter cat failed The reason is that read() immediately returns with EINVAL when asked to read more than 2GB. According to POSIX [1], if the value of nbyte passed to read() is greater than SSIZE_MAX, the result is implementation-defined. The write function has the same restriction [2]. Since OS X still supports running 32-bit executables, the 32-bit limit (SSIZE_MAX = INT_MAX = 2GB - 1) seems to be also imposed on 64-bit executables under certain conditions. For write, the problem has been addressed earlier [6c642a]. Address the problem for read() and write() differently, by limiting size of IO chunks unconditionally on all platforms in xread() and xwrite(). Large chunks only cause problems, like causing latencies when killing the process, even if OS X was not buggy. Doing IO in reasonably sized smaller chunks should have no negative impact on performance. The compat wrapper clipped_write() introduced earlier [6c642a] is not needed anymore. It will be reverted in a separate commit. The new test catches read and write problems. Note that 'git add' exits with 0 even if it prints filtering errors to stderr. The test, therefore, checks stderr. 'git add' should probably be changed (sometime in another commit) to exit with nonzero if filtering fails. The test could then be changed to use test_must_fail.

2012-02-17Add a setting to require a filter to be successfulLibravatar Jehan Bing1-0/+37
By default, a missing filter driver or a failure from the filter driver is not an error, but merely makes the filter operation a no-op pass through. This is useful to massage the content into a shape that is more convenient for the platform, filesystem, and the user to use, and the content filter mechanism is not used to turn something unusable into usable. However, we could also use of the content filtering mechanism and store the content that cannot be directly used in the repository (e.g. a UUID that refers to the true content stored outside git, or an encrypted content) and turn it into a usable form upon checkout (e.g. download the external content, or decrypt the encrypted content). For such a use case, the content cannot be used when filter driver fails, and we need a way to tell Git to abort the whole operation for such a failing or missing filter driver. Add a new "filter.<driver>.required" configuration variable to mark the second use case. When it is set, git will abort the operation when the filter driver does not exist or exits with a non-zero status code.

2011-05-26t0021-conversion.sh: fix NoTerminatingSymbolAtEOF testLibravatar René Scharfe1-11/+12
The last line of the test file "expanded-keywords" ended in a newline, which is a valid terminator for ident. Use printf instead of echo to omit it and thus really test if a file that ends unexpectedly in the middle of an ident tag is handled properly. Also take the oppertunity to calculate the expected ID dynamically instead of hardcoding it into the test script. This should make future changes easier.

2010-12-22t0021: avoid getting filter killed with SIGPIPELibravatar Junio C Hamano1-0/+1
The fake filter did not read from the standard input at all, which caused the calling side to die with SIGPIPE, depending on the timing. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-12-22convert filter: supply path to external driverLibravatar Pete Wyckoff1-0/+42
Filtering to support keyword expansion may need the name of the file being filtered. In particular, to support p4 keywords like $File: //depot/product/dir/script.sh $ the smudge filter needs to know the name of the file it is smudging. Allow "%f" in the custom filter command line specified in the configuration. This will be substituted by the filename inside a single-quote pair to be passed to the shell.

2010-04-10convert: Keep foreign $Id$ on checkout.Libravatar Henrik Grubbström1-1/+1
If there are foreign $Id$ keywords in the repository, they are most likely there for a reason. Let's keep them on checkout (which is also what the documentation indicates). Foreign $Id$ keywords are now recognized by there being multiple space separated fields in $Id:xxxxx$.

2010-01-05t0021: use $SHELL_PATH for the filter scriptLibravatar Johannes Sixt1-1/+2
On Windows, we need the shbang line to correctly invoke shell scripts via a POSIX shell, except when the script is invoked via 'sh -c' because sh (a bash) does "the right thing". But the clean and smudge filters will not always be invoked via 'sh -c'; to futureproof, we should mark the the one in t0021-conversion with #!$SHELL_PATH.

2007-10-21t0021-conversion.sh: Test that the clean filter really cleans content.Libravatar Johannes Sixt1-1/+6
This test uses a rot13 filter, which is its own inverse. It tested only that the content was the same as the original after both the 'clean' and the 'smudge' filter were applied. This way it would not detect whether any filter was run at all. Hence, here we add another test that checks that the repository contained content that was processed by the 'clean' filter.

2007-05-28Add test case for $Id$ expanded in the repositoryLibravatar Andy Parkins1-0/+36
This test case would have caught the bug fixed by revision c23290d5. It puts various forms of $Id$ into a file in the repository, without allowing git to collapse them to uniformity. Then enables the $Id$ expansion on checkout, and checks that what is checked out has coped with the various forms.

2007-05-14Use $Id$ as the ident attribute keyword rather than $ident$ to be consistent ↵Libravatar Andy Parkins1-2/+2
with other VCSs $Id$ is present already in SVN and CVS; it would mean that people converting their existing repositories won't have to make any changes to the source files should they want to make use of the ident attribute. Given that it's a feature that's meant to calm those very people, it seems obtuse to make them edit every file just to make use of it. I think that bzr uses $Id$; Mercurial has examples hooks for $Id$; monotone has $Id$ on its wishlist. I can't think of a good reason not to stick with the de-facto standard and call ours $Id$ instead of $ident$.

2007-04-24Add 'filter' attribute and external filter driver definition.Libravatar Junio C Hamano1-0/+9
The interface is similar to the custom low-level merge drivers. First you configure your filter driver by defining 'filter.<name>.*' variables in the configuration. filter.<name>.clean filter command to run upon checkin filter.<name>.smudge filter command to run upon checkout Then you assign filter attribute to each path, whose name matches the custom filter driver's name. Example: (in .gitattributes) *.c filter=indent (in config) [filter "indent"] clean = indent smudge = cat Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-04-24Add 'ident' conversion.Libravatar Junio C Hamano1-0/+39
The 'ident' attribute set to path squashes "$ident:<any bytes except dollor sign>$" to "$ident$" upon checkin, and expands it to "$ident: <blob SHA-1> $" upon checkout. As we have two conversions that affect checkin/checkout paths, clarify how they interact with each other. Signed-off-by: Junio C Hamano <junkio@cox.net>
