2011-08-22read_gitfile_gently(): rename misnamed function to read_gitfile()Libravatar Junio C Hamano1-1/+1
The function was not gentle at all to the callers and died without giving them a chance to deal with possible errors. Rename it to read_gitfile(), and update all the callers. As no existing caller needs a true "gently" variant, we do not bother adding one at this point. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-08-11ls-files: fix pathspec display on errorLibravatar Clemens Buchacher1-1/+1
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.

2011-06-10zlib: zlib can only process 4GB at a timeLibravatar Junio C Hamano1-13/+22
The size of objects we read from the repository and data we try to put into the repository are represented in "unsigned long", so that on larger architectures we can handle objects that weigh more than 4GB. But the interface defined in zlib.h to communicate with inflate/deflate limits avail_in (how many bytes of input are we calling zlib with) and avail_out (how many bytes of output from zlib are we ready to accept) fields effectively to 4GB by defining their type to be uInt. In many places in our code, we allocate a large buffer (e.g. mmap'ing a large loose object file) and tell zlib its size by assigning the size to avail_in field of the stream, but that will truncate the high octets of the real size. The worst part of this story is that we often pass around z_stream (the state object used by zlib) to keep track of the number of used bytes in input/output buffer by inspecting these two fields, which practically limits our callchain to the same 4GB limit. Wrap z_stream in another structure git_zstream that can express avail_in and avail_out in unsigned long. For now, just die() when the caller gives a size that cannot be given to a single zlib call. In later patches in the series, we would make git_inflate() and git_deflate() internally loop to give callers an illusion that our "improved" version of zlib interface can operate on a buffer larger than 4GB in one go.

2011-06-10zlib: wrap deflate side of the APILibravatar Junio C Hamano1-0/+6
Wrap deflateInit, deflate, and deflateEnd for everybody, and the sole use of deflateInit2 in remote-curl.c to tell the library to use gzip header and trailer in git_deflate_init_gzip(). There is only one caller that cares about the status from deflateEnd(). Introduce git_deflate_end_gently() to let that sole caller retrieve the status and act on it (i.e. die) for now, but we would probably want to make inflate_end/deflate_end die when they ran out of memory and get rid of the _gently() kind.

2011-05-15read_sha1_file(): allow selective bypassing of replacement mechanismLibravatar Junio C Hamano1-1/+6
The way "object replacement" mechanism was tucked to the read_sha1_file() interface was suboptimal in a couple of ways: - Callers that want it to die with useful diagnosis upon seeing a corrupt object does not have a way to say that they do not want any object replacement. - Callers who do not want it to die but want to handle the errors themselves are told to arrange to call read_object(), but the function does not use the replacement mechanism, and also it is a file scope static function that not many callers can call to begin with. This adds a read_sha1_file_extended() that takes a set of flags; the callers of read_sha1_file() passes a flag READ_SHA1_FILE_REPLACE to ask for object replacement mechanism to kick in. Later, we could add another flag bit to tell the function to return an error instead of dying and then remove the misguided "call read_object() yourself".

2011-05-15inline lookup_replace_object() callsLibravatar Junio C Hamano1-2/+10
In a repository without object replacement, lookup_replace_object() should be a no-op. Check the flag "read_replace_refs" on the side of the caller, and bypess a function call when we know we are not dealing with replacement. Also, even when we are set up to replace objects, if we do not find any replacement defined, flip that flag off to avoid function call overhead for all the later object accesses. As this change the semantics of the flag from "do we need read the replacement definition?" to "do we need to check with the lookup table?" the flag needs to be renamed later to something saner, e.g. "use_replace", when the codebase is calmer, but not now.

2011-05-15read_sha1_file(): get rid of read_sha1_file_repl() madnessLibravatar Junio C Hamano1-5/+1
Most callers want to silently get a replacement object, and they do not care what the real name of the replacement object is. Worse yet, no sane interface to return the underlying object without replacement is provided. Remove the function and make only the few callers that want the name of the replacement object find it themselves. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-05-10fix overslow :/no-such-string-ever-existed diagnosticsLibravatar Junio C Hamano1-4/+4
"git cmd :/no-such-string-ever-existed" runs an extra round of get_sha1() since 009fee4 (Detailed diagnosis when parsing an object name fails., 2009-12-07). Once without error diagnosis to see there is no commit with such a string in the log message (hence "it cannot be a ref"), and after seeing that :/no-such-string-ever-existed is not a filename (hence "it cannot be a path, either"), another time to give "better diagnosis". The thing is, the second time it runs, we already know that traversing the history all the way down to the root will _not_ find any matching commit. Rename misguided "gently" parameter, which is turned off _only_ when the "detailed diagnosis" codepath knows that it cannot be a ref and making the call only for the caller to die with a message. Flip its meaning (and adjust the callers) and call it "only_to_die", which is not a great name, but it describes far more clearly what the codepaths that switches their behaviour based on this variable do. On my box, the command spends ~1.8 seconds without the patch to make the report; with the patch it spends ~1.12 seconds. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-05-09convert: rename the "eol" global variable to "core_eol"Libravatar Junio C Hamano1-1/+1
Yes, it is clear that "eol" wants to mean some sort of end-of-line thing, but as the name of a global variable, it is way too short to describe what kind of end-of-line thing it wants to represent. Besides, there are many codepaths that want to use their own local "char *eol" variable to point at the end of the current line they are processing. This global variable holds what we read from core.eol configuration variable. Name it as such. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-03-23rerere: make sure it works even in a workdir attached to a young repositoryLibravatar Junio C Hamano1-0/+1
The git-new-workdir script in contrib/ makes a new work tree by sharing many subdirectories of the .git directory with the original repository. When rerere.enabled is set in the original repository, but the user has not encountered any conflicts yet, the original repository may not yet have .git/rr-cache directory. When rerere wants to run in a new work tree created from such a young original repository, it fails to mkdir(2) .git/rr-cache that is a symlink to a yet-to-be-created directory. There are three possible approaches to this: - A naive solution is not to create a symlink in the git-new-workdir script to a directory the original does not have (yet). This is not a solution, as we tend to lazily create subdirectories of .git/, and having rerere.enabled configuration set is a strong indication that the user _wants_ to have this lazy creation to happen; - We could always create .git/rr-cache upon repository creation. This is tempting but will not help people with existing repositories. - Detect this case by seeing that mkdir(2) failed with EEXIST, checking that the path is a symlink, and try running mkdir(2) on the link target. This patch solves the issue by doing the third one. Strictly speaking, this is incomplete. It does not attempt to handle relative symbolic link that points into the original repository, but this is good enough to help people who use contrib/workdir/git-new-workdir script.
