history

I got another libgit2 issue and will be very grateful for your help. I'm trying to retrieve file history, i.e. list of commits where this file was changed. And it seems to be quite unconventional... As far as I can see, there are no function for that. The only approach I can come up with is to use revision walking API to iterate through revisions, check the tree object attached to commit and search for given file there, if found, add commit to my list, otherwise proceed to next commit. But it looks none-optimal for me... May be is there any other approach, for example, look directly into .git

It has always struck me as strange that the C function "fopen" takes a "const char *" as the second argument. I would think it would be easier to both read your code and implement the library's code if there were bit masks defined in stdio.h, like "IO_READ" and such, so you could do things like: FILE* myFile = fopen("file.txt", IO_READ | IO_WRITE); Is there a programmatic reason for the way it actually is, or is it just historic? (i.e. "That's just the way it is.") One word : legacy. Unfortunately we have to live with it. Just speculation : Maybe at the time a "const char *" seemed more

If we need to write a new line to a file we have to code: file_output.write('Fooo line \n') Are there any reasons why Python does not have a writeln() method? It was omitted to provide a symmetric interface of the file methods and because a writeln() would make no sense: read() matches write() : they both operate on raw data readlines() matches writelines() : they both operate on lines including their EOLs readline() is rarely used; an iterator does the same job (except for the optional size param) A writeline() (or writeln() ) would be essentially the same as write() , since it wouldn't add

I am developing an app with numerous Activities. I would like to create a persistent notification that (more or less) says, "AppName - Return to AppName" that will be present whenever my background services are running. Creating and disposing of the notification was no problem. Now, the user could be on any of several screens/Activities, leave the application, then want to re-enter the app via the notification. The problem is , the notification must have an intent, which launches a predetermined Activity . I want the notification to re-enter the app in whatever Activity is at the top of the

Why are regular expressions called regular expressions? They are based on regular languages . Why are they called "regular expressions?" Regular expressions trace back to the work of an American mathematician by the name of Stephen Kleene (one of the most influential figures in the development of theoretical computer science) who developed regular expressions as a notation for describing what he called "the algebra of regular sets." His work eventually found its way into some early efforts with computational search algorithms, and from there to some of the earliest text-manipulation tools on

Terminating a MySQL query with \G instead of ; will cause MySQL to return the result set in vertical format, which is sometimes easier to read if the number of returned columns is large. Example: mysql> SELECT * FROM help_keyword LIMIT 3\G *************************** 1. row *************************** help_keyword_id: 0 name: JOIN *************************** 2. row *************************** help_keyword_id: 1 name: REPEAT *************************** 3. row *************************** help_keyword_id: 2 name: SERIALIZABLE 3 rows in set (0.00 sec) My question asked out of pure curiosity: Is
