2011-05-27gitweb.js: use setTimeout rather than setInterval in blame_incremental.jsLibravatar Jakub Narebski1-15/+40
If there is a possibility that your logic could take longer to execute than the interval time, it is recommended that you recursively call a named function using window.setTimeout rather than window.setInterval. Therefore instead of using setInterval as an alternate way of invoking handleResponse (because some web browsers call onreadystatechange only once per each distinct state, and not for each server flush), use setTimeout and reset it from handleResponse. As a bonus this allows us to get rid of timer if it turns out that web browser calls onreadystatechange on each server flush. While at it get rid of `xhr' global variable, creating it instead as local variable in startBlame and passing it as parameter, and of `pollTimer' global variable, passing it as member of xhr object (xhr.pollTimer).

2011-05-27gitweb.js: No need for loop in blame_incremental's handleResponse()Libravatar Jakub Narebski1-9/+4
JavaScript is single-threaded, so there is no need for protecting against changes to XMLHttpRequest object behind event handler back. Therefore there is no need for loop that was here in case `xhr' got new changes while processing current changes. This should make code a bit more clear.

2011-05-27gitweb.js: No need for inProgress in blame_incremental.jsLibravatar Jakub Narebski1-18/+3
JavaScript is single-threaded, so there is no need for protection against re-entrancy via inProgress variable. In particular calls to setInterval handler are stacked if handler doesn't finish before new interrupt (before new interval). The same happens with events - they are (hopefully) stacked if even handler didn't finish work. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-05-24gitweb.js: Update and improve comments in JavaScript filesLibravatar Jakub Narebski1-11/+11
This consists of adding a few extra explanation, fixing descriptions of functions to match names of parameters in code, adding a few separators, and fixing spelling -- while at it spell 'neighbor' using American spelling (and not as 'neighbour'). This is post-split cleanup. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-05-24gitweb: Split JavaScript for maintability, combining on buildLibravatar Jakub Narebski1-0/+687
Split originally single gitweb.js file into smaller files, each dealing with single issue / area of responsibility. This move should make gitweb's JavaScript code easier to maintain. For better webapp performance it is recommended[1][2][3] to combine JavaScript files. Do it during build time (in gitweb/Makefile), by straight concatenation of files into gitweb.js file (which is now ignored as being generated). This means that there are no changes to gitweb script itself - it still uses gitweb.js or gitweb.min.js, but now generated.
