This changes the on disk format for new raw reports to be gzip
compressed. Also adds the ability to serve these reports in plain text,
to insulate web browsers from the change (previously we just served the
raw reports from disk using Caddy).
* lib/model: Don't panic on failed chmod-back on directory (fixes#5836)
This makes the "in writable dir"-wrapper log chmod-back errors instead
of panicking. To do that we need a logger so the function moved into the
model package which is also the only place it's used. The tests came
along.
(The test also exercised osutil.RenameOrCopy like some sort of
piggybacking. I removed that.)
This adds a set of magical environment variables that can be used to
tweak the database parameters. It's totally undocumented and not
intended to be a long term or supported thing.
It's ugly, but there is a backstory. I have a couple of large
installations where the database options are inefficient or otherwise
suboptimal (24/7 compaction going on and stuff like that). I don't
*know* the correct database parameters, nor yet the formula or method to
derive them by, so this requires experimentation. Experimentation needs
to happen partly in production, and rolling out new builds for every
tweak isn't practical. This provides override points for all reasonable
values, while not changing anything by default.
Ideally, at the end of such experimentation, we'll know which values are
relevant to change and in what manner, and can provide a more user
friendly knob to do so - or do it automatically based on the database
size.

Per the sync/atomic bug note:
> On ARM, x86-32, and 32-bit MIPS, it is the caller's

All atomic accesses of 64-bit variables in syncthing code base are
currently ok (i.e they are all 64-bit aligned).
Generally, the bug is triggered because of incorrect alignement
of struct fields. Free variables (declared in a function) are
guaranteed to be 64-bit aligned by the Go compiler.
To ensure the code remains correct upon further addition/removal
of fields, which would change the currently correct alignment, I
added the following comment where required:
// atomic, must remain 64-bit aligned

* lib/versioner: Add placeholder to provide the absolute file path to external commands
This commit adds support for a new placeholder, %FILE_PATH_FULL%, to the
command of the external versioner. The placeholder will be replaced by
the absolute path of the file that should be deleted.
* Revert "lib/versioner: Add placeholder to provide the absolute file path to external commands"
This reverts commit fb48962b947358e90a76e87a7794adb6057de476.
* lib/versioner: Replace all placeholders in external command (fixes#5849)
Before this commit, only these placeholders were replaced that span a
whole word, for example "%FOLDER_PATH%". Words that consisted of more
than one placeholder or additional characters, for example
"%FOLDER_PATH%/%FILE_PATH%", were left untouched.
* fixup! lib/versioner: Replace all placeholders in external command (fixes#5849)
Use a global raven.Client because they allocate an http.Client for each,
with a separate CA bundle and infinite connection idle time. Infinite
connection idle time means that if the client is never used again it
will always keep the connection around, not verifying whether it's
closed server side or not. This leaks about a megabyte of memory for
each client every created.
client.Close() doesn't help with this because the http.Client is still
around, retained by its own goroutines.
The thing with the map is just to retain the API on sendReport, even
though there will in practice only ever be one DSN per process
instance...
