Julius Volz acbc2b8cb6 storage: Fix float->uint conversions on some compilers. 
See https://github.com/prometheus/prometheus/issues/887, which will at
least be partially fixed by this.

From the spec https://golang.org/ref/spec#Conversions:

"In all non-constant conversions involving floating-point or complex
values, if the result type cannot represent the value the conversion
succeeds but the result value is implementation-dependent."

This ended up setting the converted values to 0 on Debian's Go 1.4.2
compiler, at least on 32-bit Debians.

Fabian Reinartz dc7d27ab9a retrieval: add honor label handling and parametrized querying. 
This commit adds the honor_labels and params arguments to the scrape
config. This allows to specify query parameters used by the scrapers
and handling scraped labels with precedence.

beorn7 9016917d1c Increment dirty counter only if setDirty(true) is called. 
Currently, we increment the counter even if setDirty(false) is called,
which sets the storage clean.

Fabian Reinartz 1eff186555 Merge pull request #810 from prometheus/fabxc/lmatch 
Match empty labels.
 2015-06-22 15:45:50 +02:00
Fabian Reinartz 5b91ea9b36 storage: improve label matching and allow unset matching. 
Matching of empty labels now also matches metrics where the label
was not explicitly set to the empty string.

Fabian Reinartz aff01e29c3 Limit retrievable samples to retention window. 
The storage does not delete data immediately after the retention period.
We don't want to retrieve this data as it causes artifacts.

Fabian Reinartz a92134a947 Merge pull request #724 from prometheus/fabxc/storage-startup 
Read from indexing queue during crash recovery.
 2015-05-23 16:50:47 +02:00
Fabian Reinartz 6e319532cf Read from indexing queue during crash recovery. 
Change #704 introduced a regression that started reading the queue only
after potential crash recovery. When more than the queue capacity was
indexed, Prometheus deadlocked.

beorn7 3b9c421a69 Weed out all the [Gg]et* method names. 
The only exception is getNumChunksToPersist to avoid naming the struct
member numChunksToPersist in a weird way.

Julius Volz 267fd34156 Switch Prometheus to use github.com/prometheus/log. 
This change is conceptually very simple, although the diff is large. It
switches logging from "github.com/golang/glog" to
"github.com/prometheus/log", while not actually changing any log
messages. V(1)-style logging has been changed to be log.Debug*().

Fabian Reinartz 32b7595c47 Create promql package with lexer/parser. 
This commit creates a (so far unused) package. It contains the a custom
lexer/parser for the query language.

ast.go: New AST that interacts well with the parser.
lex.go: Custom lexer (new).
lex_test.go: Lexer tests (new).
parse.go: Custom parser (new).
parse_test.go: Parser tests (new).
functions.go: Changed function type, dummies for parser testing (barely changed/dummies).
printer.go: Adapted from rules/ and adjusted to new AST (mostly unchanged, few additions).

beorn7 b02d900e61 Improve chunk and chunkDesc loading. 
Also, clean up some things in the code (especially introduction of the
chunkLenWithHeader constant to avoid the same expression all over the place).

Benchmark results:

Note that everything is obviously loaded from the page cache (as the
benchmark runs thousands of times with very small series files). In a
real-world scenario, I expect a larger impact, as the disk operations
will more often actually hit the disk. To load ~50 sequential chunks,
this reduces the iops from 100 seeks and 100 reads to 1 seek and 1
read.

beorn7 c5fa0b90c3 Fix the case where a series in memory has 0 chunks, but chunks on disk. 
This is actually completely normal for a freshly unarchived series.

Test added to expose.

This will make in-memory series maintenance the faster the more chunks
are waiting for persistence.
