[fossil-users] History for a particular file
In src/info.c, just before the finfo_page, add this code
below. Then
fossil finfo
Gives you the change history for a file. This is my first attempt at
doing anything inside fossil. Suggestions welcome.
- Venks
/*
** COMMAND: finfo FILENAME
**
** Print the complete change history for a single file.
*/
void finfo_cmd(void){
Stmt q;
int vid;
Blob dest;
const char *zFilename;
db_must_be_within_tree();
vid = db_lget_int("checkout", 0);
if( vid==0 ){
fossil_panic("no checkout to finfo files in");
}
if (g.argc<3) {
usage("FILENAME");
}
file_tree_name(g.argv[2], &dest, 1);
zFilename = blob_str(&dest);
db_prepare(&q,
"SELECT substr(b.uuid,1,10), datetime(event.mtime,'localtime'),"
" coalesce(event.ecomment, event.comment),"
" coalesce(event.euser, event.user),"
" mlink.pid, mlink.fid, mlink.mid, mlink.fnid, ci.uuid"
" FROM mlink, blob b, event, blob ci"
" WHERE mlink.fnid=(SELECT fnid FROM filename WHERE name=%Q)"
" AND b.rid=mlink.fid"
" AND event.objid=mlink.mid"
" AND event.objid=ci.rid"
" ORDER BY event.mtime DESC",
zFilename
);
printf("History of %s\n", zFilename);
while( db_step(&q)==SQLITE_ROW ){
const char *zUuid = db_column_text(&q, 0);
const char *zDate = db_column_text(&q, 1);
const char *zCom = db_column_text(&q, 2);
const char *zUser = db_column_text(&q, 3);
printf("Ver %.10s by %.10s on %.10s: %s\n", zUuid, zUser, zDate, zCom );
}
db_finalize(&q);
blob_reset(&dest);

Consider using the comment_print() function located in comformat.c in
order to wrap the lines of output to no more than 79 characters per
line.

Re: [fossil-users] History for a particular file
Thanks. Naively:
while( db_step(&q)==SQLITE_ROW ){
Blob line;
const char *zUuid = db_column_text(&q, 0);
const char *zDate = db_column_text(&q, 1);
const char *zCom = db_column_text(&q, 2);
const char *zUser = db_column_text(&q, 3);
blob_zero(&line);
blob_appendf(&line, "%.10s by %.10s on %.10s: %s\n", zUuid, zUser, zDate,
zCom);
comment_print(blob_str(&line), 4, 72);
blob_reset(&line);
}

Hi Venkat,
This is very helpful. Are you planning to commit it?

Re: [fossil-users] History for a particular file
I would like to see this feature in fossil.

i believe that will avoid re-allocating the buffer string on each loop
iteration (it will only need to allocate on the first iteration and on
iterations where the output is larger than any previous iteration).
That is, if i remember the internals of Blob correctly.

Re: [fossil-users] History for a particular file
I am not sure how to get it in, and if it's even worthy of getting in. I made some mods. 1. add help 2. add -l option (for brief and verbose histories) 3. report error for unknown files.
