2016-05-17fast-import: do not truncate exported marks fileLibravatar Felipe Contreras1-0/+15
Certain lines of the marks file might be corrupted (or the objects missing due to a garbage collection), but that's no reason to truncate the file and essentially destroy the rest of it. Ideally missing objects should not cause a crash, we could just skip them, but that's another patch.

2016-03-05strbuf_getwholeline: NUL-terminate getdelim buffer on errorLibravatar Jeff King1-0/+4
Commit 0cc30e0 (strbuf_getwholeline: use getdelim if it is available, 2015-04-16) tries to clean up after getdelim() returns EOF, but gets one case wrong, which can lead in some obscure cases to us reading uninitialized memory. After getdelim() returns -1, we re-initialize the strbuf only if sb->buf is NULL. The thinking was that either: 1. We fed an existing allocated buffer to getdelim(), and at most it would have realloc'd, leaving our NUL in place. 2. We didn't have a buffer to feed, so we gave getdelim() NULL; sb->buf will remain NULL, and we just want to restore the empty slopbuf. But that second case isn't quite right. getdelim() may allocate a buffer, write nothing into it, and then return EOF. The resulting strbuf rightfully has sb->len set to "0", but is missing the NUL terminator in the first byte. Most call-sites are fine with this. They see the EOF and don't bother looking at the strbuf. Or they notice that sb->len is empty, and don't look at the contents. But there's at least one case that does neither, and relies on parsing the resulting (possibly zero-length) string: fast-import. You can see this in action with the new test (though we probably only notice failure there when run with --valgrind or ASAN). We can fix this by unconditionally resetting the strbuf when we have a buffer after getdelim(). That fixes case 2 above. Case 1 is probably already fine in practice, but it does not hurt for us to re-assert our invariants (especially because we are relying on whatever getdelim() happens to do, which may vary from platform to platform). Our fix covers that case, too. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-01-12t9300-fast-import.sh: use the $( ... ) construct for command substitutionLibravatar Elia Pinto1-34/+34
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.

This does not have an effect now, but will remove some noise from the git diff -b output of the next commit. The change here is entirely automated with this perl command: perl -i -lpe 's/(cat.*<<) *((EOF|(EXPECT|INPUT)_END).*$)/$1-$2 &&/' t/t9300-fast-import.sh i.e., inserts a dash between << and the EOF word (and removes blanks that our style guide abhors) and appends the && that will become necessary.

2015-07-01fast-import: add a get-mark commandLibravatar Michael Haggerty1-0/+13
It is sometimes useful for importers to be able to read the SHA-1 corresponding to a mark that they have created via fast-import. For example, they might want to embed the SHA-1 into the commit message of a later commit. Or it might be useful for internal bookkeeping uses, or for logging. Add a "get-mark" command to "git fast-import" that allows the importer to ask for the value of a mark that has been created earlier.

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.

2012-04-10fast-import: tighten parsing of datarefsLibravatar Pete Wyckoff1-0/+287
The syntax for the use of mark references in fast-import demands either a SP (space) or LF (end-of-line) after a mark reference. Fast-import does not complain when garbage appears after a mark reference in some cases. Factor out parsing of mark references and complain if errant characters are found. Also be a little more careful when parsing "inline" and SHA1s, complaining if extra characters appear or if the form of the dataref is unrecognized. Buggy input can cause fast-import to produce the wrong output, silently, without error. This makes it difficult to track down buggy generators of fast-import streams. An example is seen in the last line of this commit command: commit refs/heads/S2 committer Name <name@example.com> 1112912893 -0400 data <<COMMIT commit message COMMIT from :1M 100644 :103 hello.c It is missing a newline and should be: [...] from :1 M 100644 :103 hello.c What fast-import does is to produce a commit with the same contents for hello.c as in refs/heads/S2^. What the buggy program was expecting was the contents of blob :103. While the resulting commit graph looked correct, the contents in some commits were wrong.

2012-03-16Merge "two fixes for fast-import's 'ls' command" from JonathanLibravatar Junio C Hamano1-0/+39
Andrew Sayers noticed that the svn-fe | git fast-import pipeline mishandles a subversion history that copies the root directory to a sub-directory (e.g. doing `svn cp . trunk` to standardise your layout). As David Barr explained, the bug arises when the following command is sent to git fast-import: 'ls' SP ':1' SP LF Instead of reading back what is at the root of r1, it unconditionally reports the path as missing. After sleeping on it, here are two patches for 'maint'. One plugs a memory leak. The other ensures that trying to pass an empty path to the 'ls' command results in an error message that can help the frontend author instead of the silently broken conversion Andrew found. Then we can carefully add 'ls ""' support in 1.7.11. * commit 'refs/pull-request-tags/jn/maint-fast-import-empty-ls': fast-import: don't allow 'ls' of path with empty components fast-import: leakfix for 'ls' of dirty trees
2012-03-09fast-import: don't allow 'ls' of path with empty componentsLibravatar Jonathan Nieder1-0/+39
As the fast-import manual explains: The value of <path> must be in canonical form. That is it must not: . contain an empty directory component (e.g. foo//bar is invalid), . end with a directory separator (e.g. foo/ is invalid), . start with a directory separator (e.g. /foo is invalid), Unfortunately the "ls" command accepts these invalid syntaxes and responds by declaring that the indicated path is missing. This is too subtle and causes importers to silently misbehave; better to error out so the operator knows what's happening. The C, R, and M commands already error out for such paths.
