"git fast-export" with -M/-C option issued "copy" instruction on a path that is simultaneously modified, which was incorrect. * jt/fast-export-copy-modify-fix: fast-export: do not copy from modified file
2017-09-21fast-export: do not copy from modified fileLibravatar Jonathan Tan1-1/+19
When run with the "-C" option, fast-export writes 'C' commands in its output whenever the internal diff mechanism detects a file copy, indicating that fast-import should copy the given existing file to the given new filename. However, the diff mechanism works against the prior version of the file, whereas fast-import uses whatever is current. This causes issues when a commit both modifies a file and uses it as the source for a copy. Therefore, teach fast-export to refrain from writing 'C' when it has already written a modification command for a file. An existing test in t9350-fast-export is also fixed in this patch. The existing line "C file6 file7" copies the wrong version of file6, but it has coincidentally worked because file7 was subsequently overridden.

2017-05-10t3901: move supporting files into t/t3901/Libravatar Johannes Schindelin1-1/+1
The current convention is to either generate files on the fly in tests, or to use supporting files taken from a t/tNNNN/ directory (where NNNN matches the test's number, or the number of the test from which we borrow supporting files). The test t3901-i18n-patch.sh was obviously introduced before that convention was in full swing, hence its supporting files still lived in t/t3901-8859-1.txt and t/t3901-utf8.txt, respectively. Let's adjust to the current convention. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-01-12t9350-fast-export.sh: use the $( ... ) construct for command substitutionLibravatar Elia Pinto1-3/+3
The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}" done and then carefully proof-read.

2013-10-29t: use perl instead of "$PERL_PATH" where applicableLibravatar Jeff King1-1/+1
As of the last commit, we can use "perl" instead of "$PERL_PATH" when running tests, as the former is now a function which uses the latter. As the shorter "perl" is easier on the eyes, let's switch to using it everywhere. This is not quite a mechanical s/$PERL_PATH/perl/ replacement, though. There are some places where we invoke perl from a script we generate on the fly, and those scripts do not have access to our internal shell functions. The result can be double-checked by running: ln -s /bin/false bin-wrappers/perl make test which continues to pass even after this patch.

2013-06-07tests: use test_ln_s_add to remove SYMLINKS prerequisite (trivial cases)Libravatar Johannes Sixt1-3/+2
There are many instances where the treatment of symbolic links in the object model and the algorithms are tested, but where it is not necessary to actually have a symbolic link in the worktree. Make adjustments to the tests and remove the SYMLINKS prerequisite when appropriate in trivial cases, where "trivial" means: - merely a replacement of 'ln -s a b && git add b' by test_ln_s_add is needed; - a test for symbolic link on the file system can be split off (and remains protected by SYMLINKS); - existing code is equivalent to test_ln_s_add.

2012-12-03fast-export: make sure updated refs get updatedLibravatar Felipe Contreras1-0/+15
When an object has already been exported (and thus is in the marks) it's flagged as SHOWN, so it will not be exported again, even if in a later time it's exported through a different ref. We don't need the object to be exported again, but we want the ref updated, which doesn't happen. Since we can't know if a ref was exported or not, let's just assume that if the commit was marked (flags & SHOWN), the user still wants the ref updated. IOW: If it's specified in the command line, it will get updated, regardless of whether or not the object was marked. So: % git branch test master % git fast-export $mark_flags master % git fast-export $mark_flags test Would export 'test' properly. Additionally, this fixes issues with remote helpers; now they can push refs whose objects have already been exported, and a few other issues as well. Update the tests accordingly.

2012-12-03fast-export: don't handle uninteresting refsLibravatar Felipe Contreras1-0/+30
They have been marked as UNINTERESTING for a reason, lets respect that. Currently the first ref is handled properly, but not the rest. Assuming that all the refs point at the same commit in the following example: % git fast-export master ^uninteresting ^foo ^bar reset refs/heads/bar from :0 reset refs/heads/foo from :0 reset refs/heads/uninteresting from :0 % git fast-export ^uninteresting ^foo ^bar master reset refs/heads/master from :0 reset refs/heads/bar from :0 reset refs/heads/foo from :0 Clearly this is wrong; the negative refs should be ignored. After this patch: % git fast-export ^uninteresting ^foo ^bar master # nothing % git fast-export master ^uninteresting ^foo ^bar # nothing And even more, it would only happen if the ref is pointing to exactly the same commit, but not otherwise: % git fast-export ^next next reset refs/heads/next from :0 % git fast-export ^next next^{commit} # nothing % git fast-export ^next next~0 # nothing % git fast-export ^next next~1 # nothing % git fast-export ^next next~2 # nothing The reason this happens is that before traversing the commits, fast-export checks if any of the refs point to the same object, and any duplicated ref gets added to a list in order to issue 'reset' commands after the traversing. Unfortunately, it's not even checking if the commit is flagged as UNINTERESTING. The fix of course, is to check it. However, in order to do it properly we need to get the UNINTERESTING flag from the command line, not from the commit object, because "^foo bar" will mark the commit 'bar' uninteresting if foo and bar points at the same commit. rev_cmdline_info, which was introduced exactly to handle this situation, contains all the information we need for get_tags_and_duplicates(), plus the ref flag. This way the rest of the positive refs will remain untouched; it's only the negative ones that change in behavior.

2012-11-26fast-export: avoid importing blob marksLibravatar Felipe Contreras1-0/+14
We want to be able to import, and then export, using the same marks, so that we don't push things that the other side already received. Unfortunately, fast-export doesn't store blobs in the marks, but fast-import does. This creates a mismatch when fast export is reusing a mark that was previously stored by fast-import. There is no point in one tool saving blobs, and the other not, but for now let's just check in fast-export that the objects are indeed commits.

2012-07-09Merge branch 'js/fast-export-paths-with-spaces'Libravatar Junio C Hamano1-1/+1
"git fast-export" produced an input stream for fast-import without properly quoting pathnames when they contain SPs in them. * js/fast-export-paths-with-spaces: fast-export: quote paths with spaces
2012-06-27fast-export: quote paths with spacesLibravatar Jay Soffian1-1/+1
A path containing a space must be quoted when used as an argument to either the copy or rename commands (because unlike other commands, the path is not the final thing on the line for those commands). Commit 6280dfdc3b (fast-export: quote paths in output, 2011-08-05) previously attempted to fix fast-export's quoting by passing all paths through quote_c_style(). However, that function does not consider the space to be a character which requires quoting, so let's special-case the space inside print_path(). This will cause space-containing paths to also be quoted in other commands where such quoting is not strictly necessary, but it does not hurt to do so. The test from 6280dfdc3b did not detect this because, while it does introduce renames in the export stream, it does not actually turn on rename detection, so they were presented as pairs of deletions/adds. Using "-M" reveals the bug. Signed-off-by: Jay Soffian <jaysoffian@gmail.com> Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-06-12t: Replace 'perl' by $PERL_PATHLibravatar Vincent van Ravesteijn1-1/+1
GIT-BUILD-OPTIONS defines PERL_PATH to be used in the test suite. Only a few tests already actually use this variable when perl is needed. The other test just call 'perl' and it might happen that the wrong perl interpreter is used. This becomes problematic on Windows, when the perl interpreter that is compiled and installed on the Windows system is used, because this perl interpreter might introduce some unexpected LF->CRLF conversions. This patch makes sure that $PERL_PATH is used everywhere in the test suite and that the correct perl interpreter is used.

* jk/fast-export-quote-path: fast-export: quote paths in output
2011-08-05fast-export: quote paths in outputLibravatar Jeff King1-1/+27
Many pathnames in a fast-import stream need to be quoted. In particular: 1. Pathnames at the end of an "M" or "D" line need quoting if they contain a LF or start with double-quote. 2. Pathnames on a "C" or "R" line need quoting as above, but also if they contain spaces. For (1), we weren't quoting at all. For (2), we put double-quotes around the paths to handle spaces, but ignored the possibility that they would need further quoting. This patch checks whether each pathname needs c-style quoting, and uses it. This is slightly overkill for (1), which doesn't actually need to quote many characters that vanilla c-style quoting does. However, it shouldn't hurt, as any implementation needs to be ready to handle quoted strings anyway. In addition to adding a test, we have to tweak a test which blindly assumed that case (2) would always use double-quotes, whether it needed to or not.

2010-07-19fast-export: Add a --full-tree optionLibravatar Elijah Newren1-0/+5
This option adds symmetry with fast-import, enabling it to also work with complete trees instead of just incremental changes. It works by issuing a 'deleteall' directive with each commit and then listing the full set of files that make up that commit, rather than just showing the list of files that have changed since the (first) parent commit. Note that this functionality is automatically turned on when using --import-marks together with path limiting in order to avoid dropping important but unchanged files. This functionality is desired when using hand-written filters along with 'fast-export | some-filter | fast-import' as it can be easier to write <some-filter> in terms of complete trees than incremental changes. We could avoid the need to add this option by simply always turning it on. While the end result would be identical, it would slow things down slightly by printing many more filenames per commit which goes somewhat against the 'fast' in 'fast-export'.

2010-07-19fast-export: Fix dropping of files with --import-marks and path limitingLibravatar Elijah Newren1-0/+9
Since fast-export operates by listing file changes since the (first) parent commit, when using --import-marks and path limiting and using a wider list of paths than in previous runs, files from the new path(s) will silently be omitted from the result unless or until a commit which explicitly changes those files. The resulting repository in such cases is broken and makes no sense. This commit fixes this by having fast-export work with complete trees instead of incremental changes (when both --import-marks and path limiting are used). It works by issuing a 'deleteall' directive with each commit and then listing the full set of files that make up that commit, rather than just showing the list of files that have changed since the (first) parent commit.

2010-07-09fast-export: Fix output order of D/F changesLibravatar Elijah Newren1-1/+1
The fast-import stream format requires incremental changes which take place immediately, meaning that for D->F conversions all files below the relevant directory must be deleted before the resulting file of the same name is created. Reversing the order can result in fast-import silently deleting the file right after creating it, resulting in the file missing from the resulting repository.
