* object_array_entry: fix memory handling of the name fieldMichael Haggerty2013-06-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the memory management of the object_array_entry::name field was inconsistent and undocumented. object_array_entries are ultimately created by a single function, add_object_array_with_mode(), which has an argument "const char *name". This function used to simply set the name field to reference the string pointed to by the name parameter, and nobody on the object_array side ever freed the memory. Thus, it assumed that the memory for the name field would be managed by the caller, and that the lifetime of that string would be at least as long as the lifetime of the object_array_entry. But callers were inconsistent: * Some passed pointers to constant strings or argv entries, which was OK. * Some passed pointers to newly-allocated memory, but didn't arrange for the memory ever to be freed. * Some passed the return value of sha1_to_hex(), which is a pointer to a statically-allocated buffer that can be overwritten at any time. * Some passed pointers to refnames that they received from a for_each_ref()-type iteration, but the lifetimes of such refnames is not guaranteed by the refs API. Bring consistency to this mess by changing object_array to make its own copy for the object_array_entry::name field and free this memory when an object_array_entry is deleted from the array. Many callers were passing the empty string as the name parameter, so as a performance optimization, treat the empty string specially. Instead of making a copy, store a pointer to a statically-allocated empty string to object_array_entry::name. When deleting such an entry, skip the free(). Change the callers that were already passing copies to add_object_array_with_mode() to either skip the copy, or (if the memory needed to be allocated anyway) freeing the memory itself. A part of this commit effectively reverts 70d26c6e76 read_revisions_from_stdin: make copies for handle_revision_arg because the copying introduced by that commit (which is still necessary) is now done at a deeper level.

* bundle: Accept prerequisites without commit messagesLukas Fleischer2013-04-071-1/+1
| | | | | | | | | | | | | | | While explicitly stating that the commit message in a prerequisite line is optional, we required all lines with 40 or more characters to contain a space after the object name, bailing out if a line consisted of an object name only. This was to allow bundling a history to a commit without an message, but the code forgot that it already called rtrim() to remove that whitespace. As a workaround, only check for SP when the line has more than 40 characters. Signed-off-by: Lukas Fleischer <git@cryptocrack.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|\ | | | | | | | | | | | | | | * jk/fully-peeled-packed-ref: pack-refs: add fully-peeled trait pack-refs: write peeled entry for non-tags use parse_object_or_die instead of die("bad object") avoid segfaults on parse_object failure
| * avoid segfaults on parse_object failureJeff King2013-03-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many call-sites of parse_object assume that they will get a non-NULL return value; this is not the case if we encounter an error while parsing the object. This patch adds a wrapper function around parse_object that handles dying automatically, and uses it anywhere we immediately try to access the return value as a non-NULL pointer (i.e., anywhere that we would currently segfault). This wrapper may also be useful in other places. The most obvious one is code like: o = parse_object(sha1); if (!o) die(...); However, these should not be mechanically converted to parse_object_or_die, as the die message is sometimes customized. Later patches can address these sites on a case-by-case basis. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|/ | | | | | | | | | | | | | A more informative message for "complete" bundles was added in commit 8c3710fd3011 (tweak "bundle verify" of a complete history, 2012-06-04). However, the prerequisites ref list is currently read *after* we check if it equals zero, which means we never actually use the number of prerequisite refs to decide when to print the newly introduced message.

| | | | | | | | | | | | | | | | | | | | | | | A bundle that records a complete history without prerequiste is a useful way to sneakernet the sources of your configuration files under your home directory, etc. E.g. $ GIT_DIR=/srv/git/homesrc.git git bundle create x.bndl HEAD master Running "git bundle verify" on such a "complete" bundle, however, gives somewhat a funny output. $ git bundle verify x.bndl The bundle contains 2 refs b2611f37ebc7ed6435a72d77fbc5f8b48a7d7146 HEAD b2611f37ebc7ed6435a72d77fbc5f8b48a7d7146 refs/heads/master The bundle requires these 0 refs x.bndl is okay Reword "requires these 0 refs" to say "The bundle records a complete history" instead.

If in this stage git encounters an unfamiliar option, it writes a message with an unbalanced quotation mark: error: unrecognized argument: --foo' Drop the stray quote to match the "unrecognized argument: %s" message used elsewhere and save translators some work. This is mostly a futureproofing measure: for now, the "rev-list --boundary" command catches most strange arguments on its own and the above message is not seen unless you try something esoteric like "git bundle create test.bundle --header HEAD".

In other words, all that object_array_remove_duplicates() saw was the name of the *last* added boundary object. The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan the log for boundary commits, 2012-02-22) made this slightly worse: we now free the buffer at the end, so it is not even guaranteed that it still points into addressable memory by the time object_array_remove_ duplicates looks at it. On the plus side however, it was now detectable by valgrind. The fix is easy: pass a copy of the string to add_pending_object.

There was a subtle bug in the latter step: it used fgets() with a 1024-byte buffer. If the user has sufficiently long subjects (e.g., by not adhering to the git oneline-subject convention in the first place), the 'oneline' format can easily overflow the buffer. fgets() then returns the rest of the line in the next call(s). If one of these remaining parts started with '-', git-bundle would mistakenly insert it into the bundle thinking it was a boundary commit. Fix it by using strbuf_getwholeline() instead, which handles arbitrary line lengths correctly. Note that on the receiving side in parse_bundle_header() we were already using strbuf_getwholeline_fd(), so that part is safe.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | resolve_ref() may return a pointer to a static buffer, which is not safe for long-term use because if another resolve_ref() call happens, the buffer may be changed. Many call sites though do not care about this buffer. They simply check if the return value is NULL or not. Convert all these call sites to new wrappers to reduce resolve_ref() calls from 57 to 34.

The intent here is to inherit stdout to the child, which is achieved by .out = 0. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* start_command(), .in/.out/.err = -1: Callers must close the file descriptorJohannes Sixt2008-02-231-0/+1
| | | | | | | | | | | | | | | By setting .in, .out, or .err members of struct child_process to -1, the callers of start_command() can request that a pipe is allocated that talks to the child process and one end is returned by replacing -1 with the file descriptor. Previously, a flag was set (for .in and .out, but not .err) to signal finish_command() to close the pipe end that start_command() had handed out, so it was optional for callers to close the pipe, and many already do so. Now we make it mandatory to close the pipe. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
