Main issue is git log does not return >0 when file does not exists.
Other possible issues to check - cvs might want to connect to server
with cvs log. In large git archives reaching the proper record might take
longer time than ls-files.
The master_ variable holds a FileName that points to the meta-data
for this file, e.g., CVS/Entries. There is no such thing in SVN or GIT.
So we remove that variable from those classes.
Replace four cases of 'default: ;' in VCBackend.cpp with
default:
break;
Justification: Make consistent with the rest of the LyX source code.
I found no other occurences of 'default: ;' in the source.
Introduce a distinction between being read-only and having the read-only flag. A
buffer is read-only if either it has been externally modified or if it has the
read-only flag.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
FileName::tempName() created a new temp file name by using qt to create a
temporary file with a unique name, and then deleting that file and returning
the name. This was unsafe, since other processes or even other threads of the
running LyX could create files with the same name between deletion and then
using the temp name.
This is fixed by using the TempFile class instead. As a side effect, a few
cases where the temp files were not deleted after usage were fixed as well.
The only place that is still unsafe is createTmpDir().
False positive rate of hints is quite high. Although the includes can be
technically removed (due to other includes) they logically belong to the
header.
This reverts a small part of 0526eb9d and gets rid of the double calls of
SVN::findFile() and GIT::findFile(). Please note that git detection does
currently not work because of 26dd4d0c.
At this moment we do not allow comparison between arbitrary hashes,
but except GUI the code is ready.
Thanks to the powerful way of git addressing we could even ask
for comparisons like '-2 weeks back' if someone wants to play
with GuiCompareHistory.
