2009-01-06strbuf: instate cleanup rule in case of non-memory errorsLibravatar René Scharfe1-2/+9
Make all strbuf functions that can fail free() their memory on error if they have allocated it. They don't shrink buffers that have been grown, though. This allows for easier error handling, as callers only need to call strbuf_release() if A) the command succeeded or B) if they would have had to do so anyway because they added something to the strbuf themselves. Bonus hunk: document strbuf_readlink. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-11-23add strbuf_expand_dict_cb(), a helper for simple casesLibravatar René Scharfe1-0/+7
The new callback function strbuf_expand_dict_cb() can be used together with strbuf_expand() if there is only a small number of placeholders for static replacement texts. It expects its dictionary as an array of placeholder+value pairs as context parameter, terminated by an entry with the placeholder member set to NULL. The new helper is intended to aid converting the remaining calls of interpolate(). strbuf_expand() is smaller, more flexible and can be used to go faster than interpolate(), so it should replace the latter.

2008-07-22Fix two leftovers from path_list->string_listLibravatar Johannes Schindelin1-2/+2

2008-07-21Rename path_list to string_listLibravatar Johannes Schindelin2-126/+128
The name path_list was correct for the first usage of that data structure, but it really is a general-purpose string list. $ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list) $ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list) $ git mv path-list.h string-list.h $ git mv path-list.c string-list.c $ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path) $ perl -i -pe 's/path/string/g' string-list.[ch] $ git mv Documentation/technical/api-path-list.txt \ Documentation/technical/api-string-list.txt $ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths) ... and then fix all users of string-list to access the member "string" instead of "path".

2008-05-25log --graph --left-right: show left/right information in place of '*'Libravatar Adam Simpkins1-1/+1
With the --graph option, the graph already outputs 'o' instead of '*' for boundary commits. Make it emit '<' or '>' when --left-right is specified. (This change also disables the '^' prefix for UNINTERESTING commits. The graph code currently doesn't print anything special for these commits, since it assumes no UNINTERESTING, non-BOUNDARY commits are displayed. This is potentially a bug if UNINTERESTING non-BOUNDARY commits can actually be displayed via some code path.)

2008-03-05run-command: Redirect stderr to a pipe before redirecting stdout to stderrLibravatar Christian Couder1-3/+4
With this patch, in the 'start_command' function after forking we now take care of stderr in the child process before stdout. This way if 'start_command' is called with a 'child_process' argument like this: .err = -1; .stdout_to_stderr = 1; then stderr will be redirected to a pipe before stdout is redirected to stderr. So we can now get the process' stdout from the pipe (as well as its stderr). Earlier such a call would have redirected stdout to stderr before stderr was itself redirected, and therefore stdout would not have followed stderr, which would not have been very useful anyway. Update documentation in 'api-run-command.txt' accordingly.

2008-01-16close_lock_file(): new function in the lockfile APILibravatar Brandon Casey1-3/+12
The lockfile API is a handy way to obtain a file that is cleaned up if you die(). But sometimes you would need this sequence to work: 1. hold_lock_file_for_update() to get a file descriptor for writing; 2. write the contents out, without being able to decide if the results should be committed or rolled back; 3. do something else that makes the decision --- and this "something else" needs the lockfile not to have an open file descriptor for writing (e.g. Windows do not want a open file to be renamed); 4. call commit_lock_file() or rollback_lock_file() as appropriately. This adds close_lock_file() you can call between step 2 and 3 in the above sequence. Signed-off-by: Junio C Hamano <gitster@pobox.com>
