2008-10-02config.c: Tolerate UTF8 BOM at the beginning of config fileLibravatar Petr Baudis1-0/+19
Unfortunately, the abomination of Windows Notepad likes to scatted non-sensical UTF8 BOM marks across text files it edits. This is especially troublesome when editing the Git configuration file, and it does not appear to be particularly harmful to teach Git to deal with this poo in the configfile.

2008-07-28Make use of stat.ctime configurableLibravatar Alex Riesen1-0/+4
A new configuration variable 'core.trustctime' is introduced to allow ignoring st_ctime information when checking if paths in the working tree has changed, because there are situations where it produces too much false positives. Like when file system crawlers keep changing it when scanning and using the ctime for marking scanned files. The default is to notice ctime changes.

2008-07-13Move code interpreting path relative to exec-dir to new function system_path()Libravatar Steffen Prohaska1-9/+2
Expanding system paths relative to git_exec_path can be used for creating an installation that can be moved to a different directory without re-compiling. We use this approach for template_dir and the system wide gitconfig. The Windows installer (msysgit) is an example for such a setup. This commit moves common code to a new function system_path(). System paths that are to be interpreted relative to git_exec_path are passed to system_path() and the return value is used instead of the original path. system_path() prefixes a relative path with git_exec_path and leaves absolute paths unmodified. For example, we now write template_dir = system_path(DEFAULT_GIT_TEMPLATE_DIR); [j6t: moved from path.c to exec_cmd.c] Signed-off-by: Steffen Prohaska <prohaska@zib.de> Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-01Only use GIT_CONFIG in "git config", not other programsLibravatar Daniel Barkalow1-27/+20
For everything other than using "git config" to read or write a git-style config file that isn't the current repo's config file, GIT_CONFIG was actively detrimental. Rather than argue over which programs are important enough to have work anyway, just fix all of them at the root. Also removes GIT_LOCAL_CONFIG, which would only be useful for programs that do want to use global git-specific config, but not the repo's own git-specific config, and want to use some other, presumably git-specific config. Despite being documented, I can't find any sign that it was ever used. Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-06-18Add config option to enable 'fsync()' of object filesLibravatar Linus Torvalds1-0/+5
As explained in the documentation[*] this is totally useless on filesystems that do ordered/journalled data writes, but it can be a useful safety feature on filesystems like HFS+ that only journal the metadata, not the actual file contents. It defaults to off, although we could presumably in theory some day auto-enable it on a per-filesystem basis. [*] Yes, I updated the docs for the thing.

2008-02-19branch: optionally setup branch.*.merge from upstream local branchesLibravatar Jay Soffian1-0/+8
"git branch" and "git checkout -b" now honor --track option even when the upstream branch is local. Previously --track was silently ignored when forking from a local branch. Also the command did not error out when --track was explicitly asked for but the forked point specified was not an existing branch (i.e. when there is no way to set up the tracking configuration), but now it correctly does. The configuration setting branch.autosetupmerge can now be set to "always", which is equivalent to using --track from the command line. Setting branch.autosetupmerge to "true" will retain the former behavior of only setting up branch.*.merge for remote upstream branches. Includes test cases for the new functionality.

In many places we just check if a value from the config file is not NULL, then we duplicate it and return 0. This patch introduces the new 'git_config_string' function to do that. This function is also used to refactor some code in 'config.c'. Refactoring other files is left for other patches. Also not all the code in "config.c" is refactored, because the function takes a "const char **" as its first parameter, but in many places a "char *" is used instead of a "const char *".

2008-02-06safecrlf: Add mechanism to warn about irreversible crlf conversionsLibravatar Steffen Prohaska1-0/+9
CRLF conversion bears a slight chance of corrupting data. autocrlf=true will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data. If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately. Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data. This patch adds a mechanism that can either warn the user about an irreversible conversion or can even refuse to convert. The mechanism is controlled by the variable core.safecrlf, with the following values: - false: disable safecrlf mechanism - warn: warn about irreversible conversions - true: refuse irreversible conversions The default is to warn. Users are only affected by this default if core.autocrlf is set. But the current default of git is to leave core.autocrlf unset, so users will not see warnings unless they deliberately chose to activate the autocrlf mechanism. The safecrlf mechanism's details depend on the git command. The general principles when safecrlf is active (not false) are: - we warn/error out if files in the work tree can modified in an irreversible way without giving the user a chance to backup the original file. - for read-only operations that do not modify files in the work tree we do not not print annoying warnings. There are exceptions. Even though... - "git add" itself does not touch the files in the work tree, the next checkout would, so the safety triggers; - "git apply" to update a text file with a patch does touch the files in the work tree, but the operation is about text files and CRLF conversion is about fixing the line ending inconsistencies, so the safety does not trigger; - "git diff" itself does not touch the files in the work tree, it is often run to inspect the changes you intend to next "git add". To catch potential problems early, safety triggers. The concept of a safety check was originally proposed in a similar way by Linus Torvalds. Thanks to Dimitry Potapov for insisting on getting the naked LF/autocrlf=true case right. Signed-off-by: Steffen Prohaska <prohaska@zib.de>

When DEFAULT_GIT_TEMPLATE_DIR is specified as a relative path, init-db made it relative to exec_path using prefix_path(), which is wrong. prefix_path() is about a file inside the work tree.

2008-01-02config: handle lack of newline at end of file betterLibravatar Jeff King1-5/+9
The config parsing routines use the static global 'config_file' to store the FILE* pointing to the current config file being parsed. The function get_next_char() automatically converts an EOF on this file to a newline for the convenience of its callers, and it sets config_file to NULL to indicate that EOF was reached. This throws away useful information, though, since some routines want to call ftell on 'config_file' to find out exactly _where_ the routine ended. In the case of a key ending at EOF boundary, we ended up segfaulting in some cases (changing that key or adding another key in its section), or failing to provide the necessary newline (adding a new section). This patch adds a new flag to indicate EOF and uses that instead of setting config_file to NULL. It also makes sure to add newlines where necessary for truncated input. All three included tests fail without the patch. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-12-26Improve error messages when int/long cannot be parsed from configLibravatar Shawn O. Pearce1-10/+21
If a config file has become mildly corrupted due to a missing LF we may discover some other option joined up against the end of a numeric value. For example: [section] number = 1auto where the "auto" flag was meant to occur on the next line, below "number", but the missing LF has caused it to no longer be its own option. Instead the word "auto" is parsed as a 'unit factor' for the value of "number". Before this change we got the confusing error message: fatal: unknown unit: 'auto' which told us nothing about where the problem appeared. Now we get: fatal: bad config value for 'aninvalid.unit' which at least points the user in the right direction of where to search for the incorrectly formatted configuration file. Noticed by erikh on #git, which received the original error from a simple `git checkout -b` due to a midly corrupted config. Signed-off-by: Shawn O.

The `core.whitespace` configuration variable allows you to define what `diff` and `apply` should consider whitespace errors for all paths in the project (See gitlink:git-config[1]). This attribute gives you finer control per path. For example, if you have these in the .gitattributes: frotz whitespace nitfol -whitespace xyzzy whitespace=-trailing all types of whitespace problems known to git are noticed in path 'frotz' (i.e. diff shows them in diff.whitespace color, and apply warns about them), no whitespace problem is noticed in path 'nitfol', and the default types of whitespace problems except "trailing whitespace" are noticed for path 'xyzzy'. A project with mixed Python and C might want to have: *.c whitespace *.py whitespace=-indent-with-non-tab in its toplevel .gitattributes file. Signed-off-by: Junio C Hamano <gitster@pobox.com>
