# Why this change is necessary and useful
When FixIt was originally implemented, I decided to present the quick fix list containing the set of changes made to the buffers as it was thought this would be helpful and would reassure the user that the changes we made to their code made sense and were safe. Some large part of this decision was paranoia.
Since then we're using fixit code in a lot more places and the feature is pretty mature. I personally find the opening of the quick fix window to be a bit of a pain, and I quickly end up closing it manually to reclaim the space. I have literally never used it to jump to a location that was changed.
I have received recent feedback from users that "Why is it when I do a FixIt, this annoying window appears at the bottom of the screen that I can't get rid of?". Most users who are unhappy with the result of a FixIt can, and do, use the undo command as a matter of habit.
So I propose to just not auto-display the quick fix window anymore for FixIts, Renames, etc. We continue to populate the quick fix list, however, so `:copen` can be used to inspect the results, for those power users that know about quick fix lists.

Java completer can include FixIts which are applied when a completion
entry is selected. We use the existing mechanism implemented for c-sharp
to perform these edits using the CompleteDone autocommand.
However, the existing mechanism relies on pattern matching the source to
work out which item was completed. Vim patch 8.0.1493 introduces support
for user_data on completion items, so when available we populate it with
the completion array index of the item and use that to get the exact
element that was selected. This is both a lot faster and a lot more
accirate.
Of course when applying these 'FixIts' we don't interrupt the user with
confirmation or the quickfix list as this would just be annoying. If the
server reports that an edit must be made, we just make the edit. This is
achieved by adding a silent flag to ReplaceChunks.
When no argument is given to the YcmToggleLogs command, instead of displaying
the list of available logfiles, prompt the user to open (or close if already
open) one of them.
Mention in the docs that you need the exact version of Python that Vim is looking for

Do not call user's completion function if the start column is after the current
column or if there are no candidates. This avoids keeping the user in
completion mode even if there is no completion menu.
- Updated Linux64 instructions for older systems where cmake(2.8) might be causing compilation issues.
- Using cmake3 may likely address issues (in certain scenarios)
Use the timers feature to display diagnostics asynchronously instead of waiting
for an autocommand to trigger.
Increase Vim version requirement to 7.4.1578.
Drop the CursorHold and CursorHoldI autocommands.
Parse buffer on the TextChanged autocommand instead of CursorMoved.
Don't use VimEnter initialization except when stating gui

This is another attempt at:
https://github.com/Valloric/YouCompleteMe/pull/2473
Which removed the apparently flawed attempt at "lazy" loading of YCM. While it fails to get the load out of the critical startup path, it *does* serve the useful purpose when starting up gvim of avoiding a deadlock situation in gvim.
So, this time, we keep VimEnter, but only for the gui-starting case. We update the comment to explain what is actually happening. And we can keep the docs about how to defer loading.

[READY] Add client logfile
We have a lot of issue reports with Python exceptions that interrupt user workflow or even worse make the editor unusable and force users to restart it (e.g. issue https://github.com/Valloric/YouCompleteMe/issues/2192). We really want to avoid that but at the same time we can't just silence these exceptions because they are useful to debug the issue. Logging them to Vim `:messages` is not practical because we can't write to it without displaying messages in the status line which, in addition to distract users, may lead to various issues like the infamous `Press ENTER or type command to continue` message. This is why a logfile is needed.
For now, only server crashes are logged but more logging will be added: connection issues with the server (`ConnectTimeout`, `ReadTimeout`, etc. exceptions), UltiSnips unavailability, requests sent to the server, etc.
The behavior of the `:YcmToggleLogs` command is changed to accept multiple arguments where each argument is a logfile name. Each of these files is opened in a separate window or closed if already open. When no argument is given, the list of available logfiles is displayed to the user. Example:
```
Available logfiles are:
ycm_pz83u7.log
ycmd_23830_stderr_gf6j3i.log
ycmd_23830_stdout_gmpa_k.log
```
With this change and PR #2342, we will add the completers logfiles to the list of files that can be opened with the `:YcmToggleLogs` command.
A bunch of tests are added that cover almost all changes introduced by this PR.

[READY] Bumps required Vim to 7.4.143 and adopts TextChangedI.
Long and personal experience, when TextChangedI gets used, YCM seems
to perform better, diagnostics will trigger much less frequently at
inappropriate occasions, even less with whitespace agnostic triggers,
if I recall correctly...
There's a previous discussion at #1337. At the time this change was bundled in
a single pull request with other changes.
It has gone through the test of the time, sole issue I've stumbled upon was reported
by @puremourning at https://github.com/oblitum/YouCompleteMe/issues/10. This
is what me and other users of my fork use daily.

[READY] Mention all natively supported languages in documentation
We mention all supported languages except C-family languages and JavaScript in the `Semantic Completion for Other Languages` section of the documentation. Add them.
